The strength of Li Siqi and the three of them is not too strong, they only escaped from Yankai Prison for three days, and their bodies have not fully recovered, so they can not help Ding Yi much.

Ding Yi and Li Siqi surrounded Yankai Prison and walked around for a week. To be honest, the security level of Yankai Prison is quite high, and the defense is very tight, whether it is from the outside or from the inside out, it is not easy to attack or break through.

Li Siqi has imagined how to escape from prison countless times, but not once, he has put the target of escape on the prison side. Because the security level here is too high. There are many talented people in the prison, and in private, he also discusses with his fellow inmates how to escape from prison. Almost all of them are not optimistic about escaping from prison.

Li Siqi once estimated that there are almost 20 checkpoints to face in total to escape from prison, and it is quite difficult to get out and come in.

Yankai Prison, according to the sentence of the prisoners, is divided into three areas, the outermost is for prisoners like Luyuan, who have committed minor crimes. The inner layer is for prisoners who are imprisoned for more than 10 years and not more than 50 years. The innermost prisoners are those who live in life and those who have sentences of more than 50 years.

Petty offenders have more rights, and many of them work to assist in prison management, such as distributing meals, emptying toilets, and sweeping floors.

Prisoners who commit moderate crimes are organized to go to the mines to work on ores. It's just that after work, he is taken into prison and goes back to sleep in prison.

The felons were not assigned to work in production, and they were kept in the iron cells of the felons. The activity area is only three square meters. They only have 10 minutes a day.

Ding Yi carefully observed the environment around Yankai Prison and listened to Li Siqi talk about the situation inside the prison. Circling around the high wall, Ding Yi observed the prison from all levels, and to be honest, the situation was not optimistic.

"What is the situation in the prison cells?" asked Ding Yi.

"There is a cell for four people for minor offenders, two rooms for medium criminals, and a single room for serious offenders, and there is nothing in the cell except beds and the most basic daily necessities. There was a washbasin, and in addition to that, the toilet that was put in after the prisoner. Li Siqi replied.

"Such a big prison, there should be sewers and sewage pipes for eating, drinking, and Lazar, do you know this?" asked Ding Yi.

Li Siqi thought for a moment and said, "The toilets in each prison hall are cleaned by those minor criminals, and the toilets are concentrated in the septic tank on the west side of the prison...... Do you want to start there?"

Ding Yi said: "I'm not sure, but this should be a breakthrough, and the specific situation will have to be seen again." ”

Ding Yi took Li Siqi to the west side of the prison again, and they tried to find it along the perimeter of the prison for a while, but found nothing. Here, they didn't find the outlet.

By this time, the whole sky had already darkened.

"Lao Li, this prison is built on the mountainside, surrounded by dense forests, if we want to find the sewage outlet, we may be looking in the wrong direction, I think the sewage here will eventually be discharged into the surrounding rivers and streams, we might as well start here." Ding Yi said.

The two went to look for it again, and sure enough, in a stream at the foot of the mountain, they found a sewage outlet. The outfall was beneath the stream. If Ding Yi hadn't felt that there was something wrong with the color of the stream, he really couldn't find it.

This is still because Ding Yi has the qualification of eye spirit, otherwise at night, it is pitch black everywhere, and it is really not easy to find.

The two of them didn't shoot the dirty smell, jumped into the stream, and when they saw that the sewage outlet was only about 30 centimeters, Li Siqi was a little depressed.

Ding Yi and Li Siqi returned to Wang Jingxuan and their hiding place. told Dai Sheng and Wang Jingxuan about their discovery.

"It seems that the only people who have entered the prison are me and Lao Wang, and you two are answering outside. ”

Ding Yi took out two fusiform objects and handed them to Li Siqi and Dai Sheng.

"This is Xingshuo, a flying magic weapon, although you can all fly, but with such a flying magic weapon, at least it can save you some spiritual power, and at the same time, its speed is very fast, and ordinary cultivators can't catch up with it. ”

Ding Yi took out more than a dozen iron-shelled balls and said, "The red mark is an incendiary bomb, the black mark is a poisonous smoke bomb, the blue mark is a smoke bomb, and the two largest ones are burst bombs." When you use it, don't make a mistake. ”

"The direction of our breakthrough is still north, so you should pay special attention to the situation in the north, and the time I have set for the riot, it is dawn, you wait for the disturbance on our side before you start to act. Make no mistake. ”

Looking at the prison map drawn by Li Siqi and them, Ding Yi listened carefully to the suggestions of several people, and after figuring out all the details, Ding Yi took the three of them straight to the Shan Dangshan mining area.

The vast mining area is guarded by only more than 40 prison guards. There are several kinds of good quality wood spirit ores here, although the ore types are relatively simple, but Ding Yi still decided to go here first and get some spirit stones.

A few people quickly came to the periphery of the mining area, although there were also some warning formations and mechanisms here, but these were not difficult for Ding Yi. Ding Yi's can be regarded as a formation master, and he quickly led everyone to crack a peripheral warning formation and led them to break into the mining area.

With Li Siqi leading the way, the section they picked was relatively unnoticeable, and when they entered the mining area, they did not attract the attention of the guards at all. You must know that only prison inmates have always wanted to escape, and those guards could not have imagined that someone would sneak in.

There is a warehouse in the mine where spirit stones are stacked, but there are guards over there, and what Ding Yi and they have to do at night is too dangerous, and there is no need to take risks.

At the mouth of the mine, although there were also guards, Ding Yi and the others did not see a single figure when they arrived there.

Several people entered the mine smoothly, there were dozens of mines on the side of Shan Dangshan, and Ding Yi and they directly chose the largest mine.

After entering the mine, Ding Yi once again gave full play to his expertise in 'gambling stones', and without much effort, he found several wood spirit stones.

Compared to those prisoners with spiritual rings, Ding Yi and these cultivators have high mana and great magical powers, and the four of them work together, Ding Yi is responsible for prospecting, Li Siqi is responsible for mining, Wang Jingxuan is responsible for calcing, and Dai Sheng is responsible for vigilance. In about half an hour, Ding Yi and the others got one hundred and ten spirit stones in good condition. Wood spirit stones are accompanied by a small number of water spirit stones and dark spirit stones, these spirit stones are very hidden and are not easy to find, but with Ding Yi, a 'gambling stone expert', there is naturally nowhere to hide. In the end, Ding Yi got one hundred and thirty-one wood spirit stones, seven water spirit stones, and two dark spirit stones.

In fact, Lan Hanxing's application of spirit stones is not very widespread now, and spirit stones are mainly used as raw materials for refining cultivation weapons and cultivation props. In addition, the formation mage will also be used in the formation. Other than that, it is rarely widely used. Especially after the spirit stone may be used to make the spirit stone bomb, the empire has strictly controlled the spirit stone.

Dao Yuan's strong suppression of the puppet system is, in a sense, based on this. As a strategic material, spirit stones were actually noticed hundreds of years ago. The invention of the spirit stone cannon has also been centuries away. These things invented and created by human beings, in Dao Yuan's view, are unstable variables. Although he doesn't necessarily advocate retro, he still can't see that these are enough to cause changes in the entire cultivation realm.

These single spirit stones can't be made into spirit stone bombs, otherwise Ding Yi may make a few more big bombs. However, after harvesting so many spirit stones, Ding Yi was still very happy.

Several people quietly returned along the road, and the guards on this side of the mine did not notice it until the end.

"This operation, there are many variables, I can't guarantee that it will be successful, maybe Lao Wang and I will be lost in it, if you wait until eight o'clock, there is no movement here, you can fend for yourself. Ding Yi made a final confession.

Li Siqi said: "My lord, I believe that you will succeed, you are the pride of the sky with great luck, for this, I am convinced, you will continue to create miracles, this is by no means the end." ”

Dai Sheng said: "That's right, I also believe that this time we will succeed." ”

Everyone's confidence also encouraged Ding Yi to some extent, Ding Yi nodded, he and Wang Jingxuan walked into the stream, waved their hands to the two people on the shore, and one of them stabbed down.

Entering through such a filthy sewage outlet, even if he used a knife against it, Wang Jingxuan would not enter. However, since Ding Yi also went in, Wang Jingxuan had no such thoughts, and he followed Ding Yi and drilled into the sewage outlet one after another.

Halfway up the mountain, the sewage sewer in Yankai Prison is unexpectedly long, from the sewage outlet to the septic tank inside the prison, the total length is almost four or five kilometers. Entering from the bottom up, not only have to overcome the cramped, claustrophobic environment of the sewers, but also endure the extreme stench and slipperyness. In addition, the gravitational pull of gravity must be overcome from the bottom up. If it weren't for the fact that Ding Yi and Wang Jingxuan both had physical skills, ordinary cultivators would not be able to get in no matter what.

The two of them worked hard to climb all the way, but fortunately they were moving in the middle of the night, and there was not a lot of water and filth in the sewers. Otherwise, Ding Yi and the others were climbing up, and a large number of yellow and white things were pouring down on the top, this picture was unimaginable.

It took them an hour and a half to complete the length of four or five kilometers. At the top, there were several Tieshan and several mechanisms, of course, these could not stop Ding Yi and them, and finally they climbed up from the sewer smoothly.

This is a small pond next to the septic tank, where the fermented manure flows down the sewer and directly into the stream. A large iron plate, tightly seamed covered this small pool.

Ding Yi pushed it with his hand, but the iron plate was still a little heavy, and he couldn't push it, and then Wang Jingxuan also climbed up.

Wang Jingxuan is a high-level monk at the spiritual level, and his arms have almost tens of thousands of catties of strength, and this iron plate Ding Yi can't push it, but he has no problem. He lifted it up, and the whole iron plate was lifted up.

However, the iron plate was only raised two fingers high, and it could not be lifted, and it was obvious that the iron plate was still locked. Ding Yi took out the mustache's lightning sword and slashed at the chain, but he didn't expect that the chain was still made of high-strength alloy steel, Ding Yi used this sword with full strength, but failed to cut the chain, but the sound of gold and iron clashing spread far away.

Ding Yi hurriedly asked Wang Jingxuan to put down the iron plate, and the effort was not great, and several guards rushed here. After a while, they didn't notice anything unusual, and then they dispersed.

Ding Yi and the others have been enduring the filthy air for almost two hours, and then they have no choice but to continue to lame, soaking in this stinking sewage pool.

After waiting for another half an hour, Ding Yi instructed Wang Jingxuan to continue pushing the iron plate, and when the iron plate was lifted again, Ding Yi launched the secret method of the dark spirit and took the opportunity to drill out. This time, Ding Yi was not so reckless, he took out a formation disk from the storage bracelet, and first set up a silent magic circle, and then swung the lightning sword to cut the chain.

Wang Jingxuan lifted the iron plate and climbed out. Ding Yi and Wang Jingxuan hurriedly took off their clothes, and Ding Yi condensed several water balloons one after another to remove the filth from the two of them. Ding Yi took out a bottle of ointment from the storage bracelet again, and applied it to Wang Jingxuan. This is an ointment that can block the smell of the body, and has the function of blocking a certain amount of consciousness.

Ding Yi and they broke into the prison, and they had planned it in advance. All they have to do now is infiltrate the prison cells of petty criminals. Although Ding Yi had seen Li Siqi's drawings of the prison structure before, there were still some differences between looking at the graphics and looking at the real thing. The two hurriedly changed their clothes and went inside the prison.

The plan was made in advance, and the two did not panic. Although Wang Jingxuan does not have Ding Yi's dark spirit qualifications and teleportation powers, his physical skills are not practiced in vain, and his movements are extremely vigorous, and he can keep up with Ding Yi's footsteps.

Maybe no one has ever broken into the prison, and the security of Yankai Prison at the moment is not very strict.

'Whoosh, whoosh, whoosh' several thin mastiff figures appeared not far away.

Ding Yi took out a few small bags from the storage bracelet and handed them to Wang Jingxuan. Wang Jingxuan threw out the small bags from a distance.

After not doing much, the mastiffs began to act without shame, completely forgetting their duties.

Ding Yi and Wang Jingxuan sneaked into the prison for misdemeanor prisoners step by step as planned. Ding Yi is a master of formations and organs, and he takes Wang Jingxuan with him to constantly revise the route of progress. If you follow the previous route, you will inevitably encounter those organs and formations.

encountered the locked iron door, aisle, and Tie Shan's aperture, so that the two of them even saved the effort of opening the door and twisting the lock, and the two of them easily passed through with their magical powers.

The efficiency of the two is very high, and they have broken through several lines of defense one after another. Infiltrated the prison cell for the petty criminals.

The prison building of Yankai Prison is a hexagonal oversized building. Each side is more than 400 meters long and more than 40 meters high, and there are five floors in addition to the three floors.

In the corridor of each floor, there is a guardhouse, which may not have escaped from prison for hundreds of years, and the guards here are a little vain, and many people are sleeping directly.

Ding Yi and Wang Jingxuan broke into the side of the hexagon, which was relatively dim, suitable for lurking, and not easy to be discovered, Ding Yi released his divine sense, and found that the guards in this corridor were sleeping peacefully, and he gestured to Wang Jingxuan.

Ding Yi activated his spatial supernatural power and went straight through the wall. He opened the window of the corridor and let Wang Jingxuan in.

When they arrived at the prison area, Ding Yi and the others naturally couldn't break into the prison without any recklessness, in case there were prisoners in the prison who were unwilling to cooperate with them, shouting and screaming, it was not a joke.

As discussed beforehand, there is a suitable person here. Here, Ding Yi fully cooperated with Wang Jingxuan.

Most of the misdemeanor offenders are not willing to escape from prison, but there are also many prisoners who want to go out, and they actually have contact with the offender and the petty offender because of various relationships such as fellow villagers, even cases, brothers, etc.

Wang Jingxuan soon came to a prison cell. The two of them activated the secret method and drilled in.

This is a four-person prison with bunk beds, Wang Jingxuan threw himself on a bed, his hand tightly covering the prisoner who was still sleeping soundly, preventing the person from being frightened and crying out.

"Don't be afraid, lentil, I'm a gourd, I'm here to save you. Wang Jingxuan whispered to the man.

Ding Yi didn't know if the other three prisoners cooperated, so he directly and rudely ordered the three people to the black sweet hole.

Ding Yi arranged a silent magic array and signaled that Wang Jingxuan could let go, and Wang Jingxuan let go of his big hand.

"Wang, didn't you escape from prison, why did you come in again?" asked the prisoner named Lentil.

Wang Jingxuan said: "This prison escape was originally not successful, we didn't expect it to be so complicated outside, but we met a nobleman, you will never guess who we met!"

Ding Yi didn't have time to listen to the chatter between the two, so he walked straight over.

"Lentil, hello, I'm Ding Yi!"

"Lord Demon Emperor!" Lentil was taken aback, and jumped to his feet, hitting his head heavily on the top bunk bed.

Ding Yi said: "This is not the place to talk, we have limited time, this time we are going to be in prison, I only ask you, do you want to do it with us?"

"You are the legend of our Liuhua Continent, my idol, what you didn't say, I'll do it!" Lentil was excited.

"Alright, I'll untie your spirit ring first. Ding Yi motioned for Lentil to sit up, and he took out the filigree and stabbed it into the keyhole on the beam ring. With little effort, he untied the lentil's spirit ring.

The light offender only had a restraint that locked the pipa bone, and Ding Yi took out a pill from the storage bracelet and let the lentils swallow.

"Lentil, we are short on time now, we need your help, my plan is like this......" Ding Yi explained his plan to him when Lentil regained his spiritual power.
