The third level is called "Xuanwu Valley", which is a wide valley, the valley is rich in basalt, and a long dam is built in the middle, and there is a no-fly array on the top.

It stands to reason that the two sides are fighting with earth immortals and monks of the Dao, and they should come and go high and fight in the air, but the fight between immortals and demons also pays attention to step by step, and advances little by little, otherwise they will fly directly to the territory of the immortal family, and in the face of many immortal cultivators, no matter how high their skills are, they may be besieged and killed!

The back of Xuanwu Valley was almost to the periphery of the Lingyun Palace, so the Lingyun Hall sent a large number of masters, and gathered a lot of monks from various sects, and even the Buxu monks gathered tens of thousands of people, determined to defend the dam to the death, and not let the demon gate and the demon clan rush over.

The Four Holy Sects also responded to the call and sent thirty monks of the Convergence Dao, including Jiang Yunmu and Guo Zhenjun.

Before these two people came out, they all communicated with Qin Di.

Qin Di didn't have any more immortal weapons, so he gave Jiang Yunmu eighteen ninth-order spirit treasure flying arrows, and also upgraded the overlord bow to another order, becoming a sixth-order spirit treasure.

With these spirit treasure flying arrows, Jiang Yunmu was able to exert the power of the sunset divine arrow.

In addition, Qin Di also passed on the Nine Heavens of Phoenix Dance to Guo Zhenjun.

Guo Zhenjun's Ziwei Heavenly Fire had been promoted to a third-order immortal fire, and if it was used to display the Nine Heavens Mental Technique of the Phoenix Dance, it would exert a great killing effect.

Thirty monks of the Four Holy Sects, under the leadership of the fifth-order Earth Immortal Luo Xianjing, came to Xuanwu Valley, together with Zhuang Yunqing and others, a total of fifty monks, guarding a section of the dam that was five hundred zhang long.

They have only one mission, which is to hold this section of the dam for a hundred years.

Not only them, but also other sects, each sharing the task of defending a dam.

As the leader of the Immortal Sect, the Lingyun Hall has already issued a death order, demanding that all sects must complete their tasks! If the dam is breached, not only will the monks who participated in the war be imprisoned in the water prison for 50,000 years, but the broken through sect will also have to compensate a number of immortal spirit veins to those sects that bravely fight to defend the dam.

Guo Zhenjun stood on the dam, looking at the black pressure of the Demon Sect and the Demon Clan monks in the distance, and felt very heavy in his heart. He looked left and right, and found that the section of the dam defended by the Four Holy Sects was exactly in the middle, where the pressure was the greatest, and it was the easiest to break through, and once it was broken through elsewhere, they were also the most vulnerable, and they couldn't even escape.

He sent the news back to Xianmiao Peak and expressed his concern.

Qin Di went down to Xianmiao Peak, came to the scene to take a look, and found that what Guo Zhenjun said was not bad at all.

It stands to reason that this is like the water of a big river, and the position in the center has the most rapid current! From a defensive point of view, the position of the Four Holy Sects is in the middle, and it will be under the greatest pressure, which will be extremely disadvantageous to the fifty monks participating in the battle!

Qin Di knew in his heart that this was also a pit dug by the Lingyun Palace, in order to suppress the Four Holy Sects, he simply dug pits everywhere and suppressed them repeatedly! However, since the Four Holy Sects were assigned here, they couldn't directly refuse.

He walked the 500-zhang long section of the dam all over again, looked left and right, and found that the left side was the Tianxin Sect, and the right side was the Shenxiao Gate, both of which were one of the seventy-two side gates, and the strength was not too strong, but the dam defended by the two sects was also relatively short, and each sect only had a hundred zhang defense task!

The heads of the two sects arrived in person, looking at the enemy outside worriedly, not knowing if they could hold the dam and complete the task of the sect. If the task is not completed and the dam is breached, the two sects will have to pay one-third of the fairy veins, which is a punishment that hurts the muscles and bones.

Because of this, the heads of the two sects were worried, and when they saw Qin Di at this time, they hurried over to pay a visit.

Both sects have their own earth immortals to participate in the battle, but the two heads are Hedao monks, so when they meet Qin Di, they are respectful!

"Immortal Qin Chang, we're here for help!"

"In Xia Mo Bin, we Tianxin Sect only have two Earth Immortals, this time there is one, only the second order of Earth Immortals, to be honest, with us people, it is difficult to hold this section of the dam, so please think of a way, it is best to be able to complete the task, and there are not too many people falling. Qin Xianchang, you are powerful, you have the means to the sky, you must help!"

"Qin Immortal Chang, in Xia Ma Yu, although we have three earth immortals in Shenxiao Gate, but one of them has just advanced, and the other has entered the aging period, and there is only one third-order earth immortal who can really fight, compared to the demons outside, the strength is not strong enough, maybe after the first battle, all the monks we participated in the war will fall!"

Qin Di shook hands one by one, exchanged a few words, and said, "Such a long dam will definitely be breached." I don't know, who chose the line of defense, why is it so long?"

Mo Bin was a tall and thin old man, and replied in a low voice: "Immortal Chief Qin, I heard that there are rumors that the four great immortals have come to the door and secretly contacted the demon sect and the demon clan in private, and the reason why they started this big war is to consume a group of people!

Qin Di was stunned when he heard this: "There is still such a statement?"

Mo Bin took a step closer and said, "Immortal Elder Qin, you also know that after the Lingshan Heavenly Pillar topple fell, not only was part of the Immortal Mountain blessed land smashed, but also the number of immortal spirit veins was reduced, except for the spiritual veins that were fixed under the main peak of the Immortal Mountain by various sects, those wild immortal veins were all gone!

Qin Di's heart moved when he heard this, and he secretly thought: "There are so many spiritual veins near Lingshan, some of them may be related to the ancestral witch punishment heaven, and some may be the sweat flowing from his body, which turned into spiritual veins underground. Xingtian has left the locality, and the spiritual surge may indeed disappear. ”

Ma Yu was a middle-aged female cultivator who looked gloomy and said, "What Master Mo said makes sense. I've heard this kind of rumor, too. The four major lords may have reached an agreement with the demon gate and the demon clan, and want to use this battle to make it a meat grinder and let a large number of side door monks fall, so that the remaining monks can get more spiritual veins, so that they have the opportunity to be promoted to the peak of the earth immortals, and then soar into the spiritual world. ”

Hearing these words, Qin Di couldn't help but think of the wars in the history of his previous life, every time there was a large population, there would be a large-scale conquest. For example, at the end of the Qin Dynasty, in just seven years, the population of the whole country dropped sharply from 29 million to 7.5 million, a loss of 70 percent at once! Xiang Yu, the great hero of the overlord of Western Chu, killed 200,000 prisoners after a great battle. In 2 AD, Wang Mang usurped the throne of Liu Xiu and restored the Han Dynasty, and the population plummeted from 60 million to 21 million. Before the Yellow Turban Uprising, the population was 50 million, and after the Red Cliff War, there were still 6.8 million people left. In the early years of the Yuan Dynasty, the Mongolian heroes, who only knew how to bend their bows and shoot eagles, wanted to turn the Central Plains into pastures and slaughtered 20 million people in Sichuan, killing 200 million people to the point that there were still 800,000! In the 50 years of the late Ming and early Qing dynasties, 70 million people died! After each war, the people were wiped out, and the land was thousands of miles away.

He really didn't expect that after crossing the other world and choosing to cultivate immortals, he would encounter such a thing.

Qin Di frowned and thought for a while, and said, "The matter has come to this, two heads, what do you two think?"

Mo Bin spread his hands and said with a wry smile: "We can't think of a way, so we are looking forward to a few fewer deaths, Qin Xianchang, please help." ”

Ma Yu took a step closer and asked, "I heard that you can refine a third-order immortal array, can you put an immortal array out here to protect the areas guarded by our three sects?" This sect is willing to pay spirit crystals or immortal stones to seek the protection of your sect. ”

Qin Di replied: "There are no spiritual veins in the Xuanwu Valley, if you want to support the big array, you can only rely on immortal stones or spirit crystals to provide spiritual energy, and in a hundred years, I don't know how many immortal stones will be consumed." ”

Hearing this, Mo Bin said eagerly: "Do you roughly calculate, how many immortal stones are needed?" I think this battle will not last long, there must be many intervals in it, the immortal array only needs to be activated when the battle is fierce, and the two of us are willing to bear thirty percent of the spirit crystals each, what do you think?"

Qin Di glanced at the left and right sides again, and knew in his heart that he had to put out the immortal array. Because even if the fifty monks of the Four Holy Sects can hold this section of the dam, it cannot be ruled out that the demon clan will break through from elsewhere, and then go around and surround them, once they are surrounded on all sides, it is too dangerous, I am afraid that they will not even be able to escape!

So he nodded and said, "Okay, please pay a part of the spirit crystals for the two sects first, and I'll go and arrange the big array!"

The two of them were overjoyed and hurriedly thanked: "Thank you Master Qin! Thank you so much!"
