|||->-> Bazhou, also known as the lungs, here and in the Lailai area, are areas with frequent earthquakes. Crustal activity here is very frequent, with more earthquakes and volcanic eruptions than anywhere else.

There are two or three hundred large and small volcanoes in the territory of Bashizhou, and most of them are active volcanoes. Among them, there are seven or eight famous volcanoes. The whole territory of Bake Prefecture is full of smoke, and from time to time there are volcanic eruptions and earth dragons turning over. It's a very dangerous place.

Located in the south-central part of the country, there is not only the world's most famous 'Babel Volcano' in the underground world, but also the extremely famous Rock Sea. This rock sea covers an area of more than 300,000 square kilometers, from the central south to the southeast, reaching the lonely red ridge near the Shenhuo Palace. What flows in the sea of rocks is the rolling magma gushing out of various volcanoes on the side of Yanzhou......

In addition, there are more than 100 large and small lava rivers in Yanzhou. It is an extremely unsuitable area for settlement, but there are many people who are begging for a living here. Bake is a state rich in mineral resources, thanks to the abundant resources brought by volcanic eruptions, there are many 'fire fighters' here, begging for a living here.

The 'firefighters' did not live long, and very few lived past the age of forty. Everyone knows that volcanic eruptions will bring a lot of toxic sulfur gases and other harmful gases. However, the world is difficult, and the people who live here can't manage so much. They live a precarious life, working hard for their own survival, and unyielding in the struggle against fate.

Bake Prefecture is basically controlled by two major families and two medium-sized forces. The two major families are the Huangfu family and the Duanmu family, and the two major forces are the Jinquan Sect and the Rolling Stone Sect. The two great families belong to the Divine Hidden Sect, and the two major forces synthesize the Jinshi Alliance, which belongs to the Wuji Divine Palace.

However, this place now belongs to the Heavenly Dragon Kingdom, because both the Divine Hidden Gate and the Wuji Divine Palace have been merged into the Heavenly Dragon Kingdom.

Guan Zhongjian was a tall and thin man, he was the Great Grandmaster of the Blood Spirit. He was temporarily in charge of guarding the Diyuan of Yanzhou, and except for a very small number of people here, most of the people who were left behind in the Shenyin Gate and Wuji Divine Palace had moved to the underground passage.

Guan Zhongjian didn't want to stay in Bazhou for a day. The master of this bloody hand gate is extraordinary, and he is also one of the top ten masters recognized in the underground world. This is a ruthless guy, the Bloody Hand Gate was originally an underworld, a famous assassination organization.

Looking forward to the stars and the moon, I finally looked forward to Ding Yi and his party.

"Brother Tian, since you are here, can I leave? You don't know, the exercises I practice are in conflict with here, and I really can't stay for a day. As soon as Guan Zhong saw Ding Yi and them, he began to complain.

Xiahou Yi smiled and said: "You don't come, you obviously want to see Hua Cuiping, what kind of exercises do you want to fight." ”

Ding Yi said: "Lao Guan is not lying, I have also practiced the Blood Spirit Exercise, and the rhythm of the leylines here will indeed have a very big impact on the Blood Spirit Cultivators." Mr. Zhuge was not well arranged. Boss, if you want to go back, then let's go. I've worked hard for you these days. ”

Guan Zhong was overjoyed.

Ding Yi took out another storage ring and handed it to Guan Zhongji.

"Before coming to Yanzhou, I joined forces with Ni Gang Sword Forger, as well as Xiao Jinshi and Yanzhong to create a scarlet sword for you, the sword body of Olympic titanium steel, the sword spine is arranged with multiple superimposed magic arrays, the hilt is hollow, and there is a tube of dissipation in it, when you use it, be careful. This is kind of compensation for staying here. ”

This cold-blooded killer is rarely moved.

You must know that after Ding Yi appeared in the underground cultivation realm, there are many records and titles in the cultivation realm, which have changed, such as the title of Huangfu Qi's first organ master in the world, which was replaced by Ding Yi, in addition, Duanmu Lin's first array mage in the world, Xiao Jinshi's first refiner in the world, etc., were all changed hands by Ding Yi.

Although Ding Yi is not yet a Yuan-level Grand Cultivator, everyone unanimously regards him as a Yuan-level Grand Master. Some people even say that he is the first person in the underground world.

Especially Ding Yi was blessed by misfortune, and after he returned, he added the world's number one demon beast to his side, and no one would put Ding Yi as the world's first.

Although Ding Yi is famous for his puppetry, he is the top figure in formation, mechanism, and alchemy. The magic weapons and weapons refined by Ding Yi are all high-quality products. Guan Zhongjian made a lot of money this time.

"Brother Tian, I ......" Guan Zhong gradually felt a little ashamed.

"Don't be embarrassed, we haven't seen each other much, and we've always wanted to get together with you, don't forget, I'm also a Blood Spirit Cultivator, and I've always wanted to talk to you about cultivating the truth. A small meaning, not a tribute. Everyone is their own person, don't see the outside. Ding Yi said.

Guan Zhongjian didn't say anything more, he hurriedly pulled out the scarlet sword, this scarlet sword is a short sword, the whole body is blood red, the total length is one foot and six inches, activate the formation, and it can be transformed into a giant sword with a maximum of twelve meters.

This sword is a narrow sword, only two fingers wide, except for the appearance of scarlet blood, which is a little infiltrating, and the part of the sword body that leans against the sword has some serrations. In addition, the weight of this short sword is not light, it weighs more than 100 catties, and it is made by Ding Yi and the others using a lot of rare cultivation materials, combining cultivation technology, and using the secret method of cultivation to create it.

"Good sword!" Guan Zhong gradually pulled out the scarlet short sword, the style of the short sword made him very satisfied, and the bewitching scarlet color also made him like it very much.

"This sword, it is Ni Gang swordsmith, who spent more than a month studying the plan, combined with the characteristics of the old man, specially designed for you, after you go back, you have to thank him." Ding Yi said softly.

Because Ni Gang is a mortal, he is destined to be unable to refine the 'No. 1 Divine Soldier in the World'. However, he was not discouraged by his mediocre qualifications. Although he is just a mortal, he dares to pursue his dreams, Ding Yi takes special care of him, teaches him a lot of knowledge in smelting and forging, and he has high achievements in forging weapons.

Ni Qiang belongs to the Foundry Research Institute, and he is one of the very few people who has become an academician of the Research Institute with mortal qualifications. In addition, he is also a very famous weapon caster in the Celestial Dragon Kingdom. This scarlet sword

, Ding Yi just made a little effort in the superimposed formation, and at the same time, he pointed out the fire temperature, most of the credit for this sword should be attributed to Ni Gang and Xiao Jinshi.

Ding Yi has associations**, and can deduce the process of forging the sword in his mind in advance and optimize each procedural step. He also has eye spirit qualifications, and his grasp of fire is more accurate than Xiao Jinshi. Without his help, this scarlet sword would not have been able to be successfully refined in one go.

In the storage ring, there is also a page of instructions for the use of the Crimson Sword. After all, this is a magic weapon, not a mortal thing, and there are some formation arrangements in it, which require special techniques and can be activated.

"I forgot to tell you that you have now surpassed Zhou Shuguang after the argument of the Players Alliance, and you are the second master of our Heavenly Dragon Kingdom. Zhuge Qingmin congratulated this old subordinate.

Guan Zhong gradually said: "There is a problem with this ranking, Brother Tian is the number one master." ”

Ding Yi smiled: "According to what you said, the first and second should be Xiao Hei and Xiao Guang." ”

Everyone laughed.

Guan Zhong gradually received the gift, and he was in a good mood, so he stopped being busy and returned to Tianlong Kingdom, he led everyone to check around.

Jigen is located in the crater of the Tsuten Volcano, which is a huge tower-shaped building of nearly 10,000 square meters. Ding Yi didn't go directly to Tongtian Volcano, but followed Huang Fuqi and them to check around.

The whole shape of Baking Prefecture is like a super-large hot pot, with Tongtian Volcano in the middle, surrounding Tongtian Volcano, surrounded by stars, and there are nearly 100 small volcanoes of all sizes. The 'firefighters' of Yanzhou, as well as the forces of the Shenyin Gate and the Wuji Divine Palace, are all on the periphery of Yanzhou.

Even on the periphery, the living environment here is extremely sinister, but Ding Yi doesn't plan to let the people here move out now, because now is not much closer to the time of unification. Ding Yi is confident that this problem will be completely solved in about a month. However, he still asked Zhuge Qingmin and them to raise the price of ore collection, increase the amount of ore collected, and improve the living situation of the 'fire fighter' here.

After the merger into the Tianlong Kingdom, basically the acquisition of ore has been suspended in the past few months. Many of the 'firefighters' who rely on 'taking chestnuts from the fire' are about to lose their lives.

There are all the materials in the underground passage, and the most mysterious super force in the past two thousand years is only thinking about rushing out of the surface. After joining the Tianlong Kingdom, the quality of life and living environment on the side of the Tianlong Kingdom made these traditional cultivators linger and forget to return, and when they went there, they basically didn't want to come back. They have long left the affairs of Yanzhou out of the clouds. It's just that a Guan Zhongjian was sent to stay here to protect the land yuan.

The golden shells and jade shells in their hands are useless to keep, and besides, Xiahou Yi and them have integrated into the Tianlong Kingdom, and they have been somewhat influenced by the Tianlong Kingdom. Ding Yi's opinion was quickly implemented.

Ding Yi and his group of five people, from the outside to the inside, gradually deepened. Ding Yi has a better understanding of this earth element.

The five of them were all masters of the world, and this kind of volcanic area, which was difficult for low-level cultivators to penetrate, was nothing to them.

It must be said that Huang Fuqi's ancestor Huang Fu Guangming is a great strange person. His whimsy, at first glance, is whimsical, but in fact, it is quite operable.

Huangfu Guangming has laid out formations around many small volcanoes, and the purpose of these formations is to limit the eruption of volcanoes and slow down the speed of volcanic lava outflow. For nearly two thousand years, the Duanmu family has been carefully maintaining the operation of these formations.

Huangfu Guangming obviously wanted to use the power of the volcanic eruption to send the people of the Divine Hidden Gate out of the underground world. It's just that there are a lot of technical problems involved, which still need Ding Yi, and in the next time, think about it.

With a pagoda-like magic weapon, it broke through the 100-kilometer-thick rock layer, no matter how you think about it, it is still a little unlikely. However, this still has to go to the Tongtian Volcano and actually investigate it, that Jiyuan, before we can finally draw conclusions.

It took a whole day to go to the vicinity of various volcanoes to take a closer look, and the next day, Ding Yi and the others arrived at Tongtian Volcano.

Looking at the tower-shaped earth element in front of him, Ding Yi was also shocked,

This land is also too big, more than 300 meters high tower body, and there are tens of thousands of square meters of stele forest buildings on the ground. The diameter under the Diyuan Pagoda is more than 300 meters thick, and the diameter of the 39th floor on the top is also more than 20 meters thick.

The ground is not a flat piece, but the use of inlay method, and complex stacking formations, hook Xuan method, and other ancient formation techniques. In addition to the stele forest on the ground, there are many stone slabs, distributed like fish scales, and there are some metal dragons and kans between the stone slabs. However, Ding Yi still saw the doorway in the middle at a glance.

This is a chain stacking array, which is a kind of Jiyuan array. Ding Yi lay on the ground, carefully examined every stone slab, every stone tablet, and finally, he lifted more than thirty stone slabs from the ground.

"These slabs have to be repaired, and it won't take long to repair them, just minor surgery. The other components, nearly 2,000 years old, can still be well preserved, it seems that you have taken a lot of pain. Ding Yi praised from the bottom of his heart.

Huang Fu Qi is the person who knows the most about the mechanism formation in the Shenyin Gate, he has studied Di Yuan for more than 100 years, and he has never been able to get the essentials, but he didn't expect Ding Yi to come and find that there were more than 30 stone slabs on the ground that had problems, which made Huang Fu Qi very admirable.

There are still 100 meters below the ground of the Diyuan Tower, and the control system and power system of the Diyuan Tower are just below it. Everyone followed Ding Yi and entered the tower together. Ding Yi tapped the tower bricks with his fingers from time to time, observing the various reliefs in the tower very carefully, and sometimes he would use his fingers to deduct some floating ash and metal powder. Ding Yi has the qualification of Jin Ling, and it is easy to make a little scrap of scraps.

At the bottom level, there is a very large control room, with intricate and eerie mysterious symbols and patterns painted on the floor, as well as ceilings on the walls

On the board, complex formations are also drawn.

There is an altar in the control room, and in the center of the altar, there is a huge spirit orb, which should be the main hub of the Diyuan Tower. This spiritual orb is one meter in diameter, and there are countless stars and latitude and longitude lines on it.

Once again, I carefully checked the formation patterns, consoles, towers, and machines in this control room. Subsequently, Ding Yi followed Huang Fuqi and them, climbed the stairs, and began to inspect layer by layer, each layer of the tower.

There are 10 floors underground and 39 floors above ground, making a total of 49 floors. Ding Yi checked them all.

In the topmost Diyuan Tower, Ding Yi did not sell Guanzi again.

"Huangfu, tell me what you think. Ding Yi asked Huangfu Qidao.

"Teacher, this Diyuan Tower, according to the arrangement of the ancestors and the content of the notes, it should be that the ancestors wanted to use the kinetic energy generated by the volcanic eruption, accumulate energy, and penetrate the thick rock layer in one fell swoop......"

Ding Yi laughed, and he shook his head.

"This is impossible, even if the Tongtian Volcano can accumulate such a large amount of energy, it is impossible to send such a huge Earth Yuan Pagoda out of the earth. Hundreds of kilometers of thick rock layers are not something that such an earth-yuan tower can break. ”

Xiahou Yi and Zhuge Qingmin showed unbelievable looks on their faces.

"This Diyuan Tower, you can think of it, is a super cannon, the idea of the old man Huangfu Guangming, is to accumulate the energy of the volcano through the sky, keep bombarding the dome, and break through a large hole that can reach the surface. Have you noticed that the one-meter-diameter black iron ball at the top of the Diyuan Tower? This is the cannonball that the Diyuan Tower uses to fire. There is also this Diyuan Tower, it is not straight, it is not at a right angle of ninety degrees to the ground, but eighty-seven degrees five, and the Jiyuan array on the ground of this Diyuan Tower, as well as the Huilong Array and Chongling Array arranged in the tower body, all hint at this......"

After Xiahou Yi pondered for a moment, he asked Ding Yidao: "So, Ah Tian, is this method of the ancestors feasible?"

Ding Yi said: "I said before that this method is theoretically feasible, but I myself do not approve of this method. What if you're unlucky and there are water veins and magma rivers on top of the rocks? Don't think that the underground world is big enough that it should be fine. You must know that the entire Lanhan Star, 70% of the area, is an ocean. The vast majority of the planet is water.

This underground world is, at best, just a large fault space. If it breaks through the water veins of Lan Han Star, within three or two days, the monstrous flood will be able to submerge the entire underground world. ”

After hearing this, Xiahou Yi and the others were a little depressed.

Ding Yi comforted: "It's good that Mr. Huangfu can come up with this method, more than 1,900 years ago, it is very rare to have this kind of thinking and boldness." The design of the Diyuan Tower is very ingenious, and there are many places worth learning from, so don't be so frustrated. ”

Guan Zhong gradually said: "Anyway, the secret of Diyuan has now been solved, and besides, Brother Tian can't take everyone out, what's so sad." Everyone is calm......"

Xiahou Yi said: "Dozens of generations of hard work, but in the end, it is such a result, you are called an old man, how can you be calm?"

Zhuge Qingmin sighed and said, "To be honest, I am also very unwilling, but I believe in Ah Tian's judgment, and this matter will be like this." ”

Xiahou Yi pondered for a moment, and suddenly said to Ding Yi: "Ah Tian, you said that the Diyuan Pagoda is slightly repaired and can still be used, right?"

Ding Yi didn't understand the purpose of Xiahou Yi's question, but he still nodded.

Xiahou Yi asked again: "Ah Tian, I want to ask, if the Diyuan Pagoda is repaired, how far can it hit?"

Ding Yi said: "This needs to be calculated......

Xiahou Yi hurriedly said: "I didn't mean that, I just wanted to say, if we repair the Diyuan Tower, can we launch the Xuantie Ball to the Golden Dragon City?"

Zhuge Qingmin said: "Xiahou, good idea!"

Guan Zhong gradually shouted loudly. Ding Yi shook his head, but the four great masters were all in favor, and he had no reason to oppose it.

Thirty or forty stone slabs, Huang Fuqi used the gold inlay method taught to him by Ding Yi, and they began to be repaired.

Zhuge Qingmin contacted the Golden Dragon City and the spies of the Heavenly Dragon Kingdom near the Golden Dragon City, asked them to set up the observation probe, and then left quickly.

Ding Yi carefully inspected the Diyuan Pagoda again. In the underground control room of the Diyuan Tower, Ding Yi infused spiritual power into the Spirit Enlightenment Ball, and the entire turbid dark gray sphere became snow-white, and the stars and longitude and latitude lines on the Spirit Ball were projected into the control room. It formed a star map, and this star map was the same as the previous Tianyan formation on the dome.

Ding Yi played a few tricks, and soon a red point of light appeared on the Spirit Enlightenment Ball...... So it was, Ding Yi quickly understood the operation mode of this Diyuan Tower.

"Don't get excited, I changed the Tianyan Array before, so the specific point of impact still needs to be calculated. ”

Ding Yi recalculated, it didn't take much effort, and he finally found the target, and Huang Fuqi also repaired the thirty-four stone slabs and restored them.

Huang Fuqi returned to the bottom of the tower, and Ding Yi was still doing the final adjustment.

Soon Zhuge Qingmin received a reply, and he said to Ding Yi: "You can start." ”

Ding Yi nodded, he activated the Spirit Ball again, the star map appeared again, Ding Yi played a trick, controlled the Spirit Ball, and soon the red dot appeared on the star map again, Ding Yi moved the red dot with his spiritual sense, and soon the red dot fell on a position on the star map.

After playing a few spiritual tricks again, a tower-shaped mechanism rose up on the altar, and Ding Yi beckoned Zhuge Qingmin and Xiahou Yi to come over and let them put their hands on top of the mechanism.

"You use your divine sense to enter this kind of hub spirit tower, and you can start the launch......"
