It's an empty field, and there's not even a house, not a tree, which is not true if you judge by common sense.

Cheng Peng slowly spread his spiritual sense, carefully probing his surroundings. There is no phantom array, and there is no one who hides his figure.

Just as he was wondering, his spiritual sense came from a sharp spot on the surface and into the ground.

There are buried potholes! Wan Peng glanced at Xie Ting and pulled her quickly towards the pothole.

The surface of the pit is clearly buried very carefully, and as long as it is ten feet away, there is no trace to be seen. After approaching, carefully observe the entrance of this pit is about three zhang square, the floating soil is the same texture as the nearby, but it is easy to flood after being blown by the wind, and it seems that the digging time is not too long.

Wan Peng walked around the pothole, slowly squatted down, touched the ground with one hand, and launched the ground-breaking technique.

With a muffled sound, a large layer of soil floated directly, revealing a silver metal plate three feet square underneath.

Wan Peng's hand turned over, and this soil layer directly moved to the ground ten zhang away, and in the whole process, not a single sand fell. Xie Ting couldn't help but admire Wan Peng's Five Elements Spiritual Technique, she hadn't seen Wan Peng use this basic technique for a long time.

The metal plate is like a material mixed with aluminum and other metals, and it is covered with dense patterns, which obviously lays out the formation. And this formation, Wan Peng has never seen it, but a trace of it is still known, such as restraint ventilation and the like.

"Yo, there are still people who use this formation now. When Wan Peng was still observing, Liyang came out in his inner world. Wan Peng was overjoyed, and ran directly into the inner world, "What, do you know this formation?"

A layer of memories slowly appeared on the sunny side, "Of course I know." Seven thousand years ago, when the Demon Cultivator War was still in the Great War, this formation was created. It's not an offensive formation, and it's not actually a defensive formation. Liyang sighed, "But in the past, he was very prosperous in your cultivator world, and after only a few years, he was spurned by people again. ”

Wan Peng was originally interested in the formation, and it was even more exciting to hear it. "Let's talk about it in detail. ”

Liyang seemed to be sorting out his thoughts, and after a while, he said slowly, "Things still have to start with war." You must know that war is an extremely cruel thing, and there will be a large number of casualties on both sides of the war, whether they win or lose. Especially in the later stage, first, there may be more masters gradually participating in the war, and the destructive power is amazing, and second, there are many good veterans in the early stage, or people with medium cultivation, who are gradually killed and injured, and after the novices participate in the war, their experience and ability are insufficient. ”

Wan Peng nodded, this is the general law of war, even if there is a one-sided shape in the later stage, the number of casualties on the dominant side may not be less than at the beginning.

"And how to deal with these injured has become a big problem. In fact, at that time, the cultivator world was at a disadvantage, and because the medicine cultivators in charge of medical treatment were also gradually consumed in the war, the pressure on their wounded to treat was much greater than that of the demon world. If the wounded are not treated properly, many other infectious diseases can arise, such as a condition called gas gangrene, as long as one person in a group of injured people gets this disease, and the others will all develop this disease within two days, and then the wound will ulcerate and die. ”

Liyang paused for a moment, then continued, "And in this case, someone invented this formation, which is called the containment array. Its original intention was to gather the wounded together, and then avoid the wounded at different times from feeling infectious diseases and feeling each other. In the early days, it did play a role. Among the people contained in each array, there will be one or two medicinal cultivators left. ”

"But the good times didn't last long. Later, the number of medicinal cultivators decreased again, and the number of medicinal cultivators in the cultivator realm could no longer reach the number of one medicinal cultivator left in each containment array. However, in order to prevent accidents, the cultivator world still uses the containment array to contain the wounded after each war, and because there is no medicine to repair, many of these wounded died due to lack of medical treatment after being concentrated, and even among the wounded in a wave, none of them survived. So, later, it had another name, called the Self-Destruction Array. ”

After a few more years, some sects questioned the use of the array because they thought it was inhumane to ignore the wounded in this way. One stone provoked a thousand layers of Lang, first among the army, there was resistance to this formation, and then forced to respect the warriors, or it may be to coax, the cultivator realm's self-destruction formation, used less and less. Later, after some local war-like changes and the cultivator realm occupied a certain advantage, the number of wounded decreased, and they were used less. Before I was killed, unless there were more than 10,000 casualties in a battle, cultivators would no longer use this formation. ”

Wan Peng roughly understood the ins and outs of this formation, and asked, "What are its characteristics?"

Liyang said slowly, "Speaking of characteristics, this formation is also unique. First, it is based on a natural terrain, and the surface of the ground is covered with a metal compartment, on which the spiritual power is used to carve the pattern. And from the inside of the formation, unless everyone recovers, this metal compartment will automatically lose its isolation effect, otherwise, no matter how high the people inside cultivate, it is impossible to open the metal compartment. ”

"However, from the outside, it can be opened in the order of the array eyes. This one-way prohibition technique alone has a lot to study. Liyang glanced at Wan Peng, "In addition, there is another outstanding feature. Although these people are forbidden below, the air will automatically seep in, and there will be no suffocation. After the formation is activated, inside the formation, there will be some local formations similar to the phantom array, deriving a special kind of fruit tree, the fruit tree will regularly bloom and bear fruit, as if it is a week, and after ripening, this fruit can be eaten as food. ”

Wan Peng nodded slightly, "In other words, the effect of this formation is that you can get in, you can't get out, you can't suffocate, you can't starve?"

Liyang slowly nodded with his finger, "That's right, it's a good summary." He threw a ball of light to Wan Peng, "That's all my research on this formation, and the formation structure I mastered at that time. If you are interested, you can study it slowly, and some parts may be useful to you. ”

Wan Peng took the ball of light and browsed it as quickly as possible, the content involved in it is very huge, it seems to be able to form a system, if you really want to understand it, if your ability allows, it is estimated that it will take at least a day or two. He took a deep breath and looked at Wan Peng, "Have you done your research on how to open an account from the outside?"

Wan Peng nodded, "I knew you would say that." I sue you just that. To open an account from the outside, you must first find the eye of the array. The array eye is on the external pattern, which is the easiest place and pattern to communicate with the outside world. For example, if it is built in water, it may be a water number, and if it is built on a mountain, it may be a stone number.

Wan Peng's spiritual sense swept over, and what can have some characteristics on this external pattern should be a sun not far from him. There is no shelter in this position, and the sun is the easiest thing to connect with the outside world.

Liyang also confirmed it, and then said that it was right. Later, he explained: "Directly below the eye of the array, on the left and on the right, there is a dry character number for each of them, and directly above these three dry fonts, you will find three corresponding Kun font sizes. You correspond to these three sets of symbols, according to your own spiritual power, from Kun in, from Qian, after thirty-two weeks of operation, the external formation can be solved. To do this, you must be patient. Otherwise, the first time you fail, the second time, you need to run for sixty-four weeks, and the third time, it will be one hundred and twenty-eight weeks. Wan Peng nodded, quickly found these six symbols, and then signaled to Xie Ting to help him be vigilant, and he floated into the sky, drove spiritual power, and slowly entered the Kun number of the first group.

The spiritual power runs in this formation pattern for a lap, and it will not consume much, and even the running speed will hardly be affected. It's just that if you run your spiritual power in it for a long time, you will have a trace of confusion in your mind intentionally or unintentionally.

After ten weeks of operation, there was no special change in the formation. However, Wan Peng could feel that as the number of times his spiritual power ran in it increased, his own spiritual power consumption increased significantly. By the fifteenth week, he had basically reached the level of spiritual power consumption in ordinary battles, and by the twenty-fifth week, the sweat on his body was already soaked.

Week 32!

Wan Peng's spiritual power was just exhausted, and the moment he forced himself to output all his spiritual power, he fell from the air at once, and then fell onto this metal plate.

The metal plate naturally shifted to the side, revealing a large pit underneath.

Wan Peng was powerless to see what was under this metal plate, but at this time, Xie Ting stepped forward, but she was so shocked that she couldn't speak, her fingers trembled and pointed downward, and her expression was full of disbelief.

Wan Peng sat on the ground and gasped for air. If it weren't for the fine control of one's own spiritual power, this process, I am afraid that even if a trace of spiritual power is consumed, it is very likely that it will not be able to successfully open this formation. However, such a process of controlling spiritual power and consuming ethereal spiritual power at the same time has not been done for a long time, which has made the spiritual power in his body grow.

After resting for most of the incense or so, Wan Peng stood up, wiped the sweat that was still flowing on his head, and asked Xie Ting, who was still in this position, "What's wrong?"

Xie Ting didn't speak, just motioned to Wan Peng to look down.

Wan Peng frowned slightly and slowly lowered his head.

Everywhere you look, you can give people the first feeling, shocking!

This is a pit with a small belly, about ten zhang deep. There is nothing wrong with the pit alone, the key is that under the pit, there are all people!

All they saw was the bottom of the pit as far as their eyes could see. This pit seems to have a long way to go out to one side. Now, everywhere they looked, people were next to each other, most of them probably because they hadn't seen light for a long time, and they were still using their hands to shade the sun.

It is difficult to distinguish the clothes of these people because they have been mixed with the sludge for a long time, but among them, there are still people who are wearing robes that look like the robes of Poloji Temple.

At the other end of the pit were neatly stacked corpses.

This is actually a human pit, and it is also the initial use of the self-destruction array!
