Cheng Li's use of dark matter is actually inspired by sonar radar.

In nature, bats flying in the sky and dolphins swimming in the sea know how to emit ultrasound. Echo location signals are used to search for food, detect distances, determine targets, avoid obstacles, and evade enemies. Human scientists have been inspired by this to invent various sonar and radar detection systems.

Whether it is sonar or radar, it is a very sophisticated instrument. Even though Cheng Li originally belonged to a world with a very developed scientific level, it was still unable to create a sonar radar system for individual use.

But since Cheng Li has seen sonar radars, he also understands how they work. So at this moment, to use the characteristics of dark matter to turn himself into a human radar, it is not difficult for Cheng Li to say that it is not difficult to say, and it is not easy to say.

The reason why it is not difficult is that after understanding the fundamental principle, as long as you draw a gourd in the same way, you can achieve a detection effect similar to that of sonar radar, or even better. But it's not easy because it requires a very nuanced control of large amounts of dark matter. Otherwise, the detection effect will be blurred, and the details of the detection range will not be available at all, and in the end it will only be a waste of effort.

However, the larger the detection range, the greater the physical and mental burden. The general rudder of the Paijiao covers an extremely large area and has extremely complete facilities, which itself is equivalent to a small town that can accommodate tens of thousands of people.

It is necessary to thoroughly probe the whole small town, and not only the situation above the ground, but also the situation underground. Just imagining how heavy the burden is already teaches people to shudder.

In fact, if it weren't for the fact that Cheng Li had already entered the realm of the third awakening, and his spirit and body had been greatly strengthened, rashly carrying out such a large-scale probe would definitely make his body and mind unbearable, and he would finally collapse with a bang. Either you become a madman or a fool, or you become a paralyzed cripple. The end was terrible.

Although he had never tried to use dark matter in this way, Cheng Li himself had a vague premonition about the consequences that might result from doing so. But it is precisely because he has entered the third awakening and has enough confidence in himself that Cheng Li dares to boldly bring the entire platoon rudder into the detection range in one fell swoop.

In an instant, the detection results were like an endless tide, surging into Cheng Li's mind. He has to sift through the information he gets back one by one before he can get the answers he wants to know.

With his eyes half-closed, Cheng Li immersed himself in the sea of information and continued to analyze. After a long moment, he opened his eyes suddenly, his gaze drooping, and cast himself into a corner to the southwest of the helm. Then, without hesitation, he leaped forward and sprang into the corner.

In the corner where Cheng Li went, there was a warehouse, which was used to store some trivial miscellaneous items. The warehouse itself is located in a remote area, and the materials stored in it are not often accessed. So it's quiet, and there's no one to be seen.

But after Cheng Li passed the detection just now, he found that there was a tunnel hidden in the warehouse.

Cheng Li, who sneaked into the warehouse silently and like a ghost, stood in front of the entrance of the tunnel and looked around. I saw bricks and dirt scattered everywhere. He stooped down to pick up one of the broken bricks, only to see a few finger marks clearly left on it. In Cheng Li's understanding, there is only one kind of power that can leave this kind of finger marks. That's the Taiyin White Bone Claw.

Cheng Li can imagine. The brick was originally laid on the floor. Suddenly, someone used the Taiyin White Bone Claw to grab into the floor at once, and scratched through the bricks fiercely. Then up the area, immediately with bricks and soil, dig out a large piece.

Throwing away this half of the remaining brick, Cheng Li reached out to pick up another one. From the outside, the brick is still in good condition. But Cheng Li's fingertips just touched the surface of the brick, and the whole brick was completely shattered with "sand~". It's as if this fundamental brick is just a brick made of sand.

Bricks, of course, can't be pinched out of sand. There is also an explanation for the way it has become. That is, the destructive force deliberately penetrates deep into the interior of the floor tiles, destroying their structure without damaging the surface. In the usual use of martial arts, that is, the palm power of the shooter is extremely feminine, and he has almost reached the point of returning to the basics.

Those who can use this kind of feminine palm power are two in Cheng Li's understanding. One is Li Yanzhou. His Tiangang is changing, but he can be rigid and soft, yang and yin, changeable, and do whatever he wants. To completely destroy the inside of the bricks, but it looks the same on the outside, for Li Yanzhou, it is just a trivial matter.

But at this moment, Li Yanzhou should still be in Yongzhou City. With Song Shirong and the Golden Dragon Gang. This brick, of course, must not be his masterpiece. Then the only one who can do this kind of thing is obviously - Roujing!

From the remaining clues on the ground, I found clues about Xiaoqing and Bodhisattva. Cheng Lideng was in high spirits. He jumped down the tunnel. It seems that the tunnel is very narrow, and the four walls are uneven. And it's all freshly dug up dirt. It looks very rough and rudimentary. Full of the smell of impromptu urgency.

But after entering the tunnel for a kilometer or so, the situation changed suddenly. Not only is the space wider, but the walls are also smooth and flat, which is clearly once carefully retouched by craftsmen.

Continuing to go deeper, I don't know how long it took, suddenly, Cheng Li only felt that the surroundings were empty, and he had already left the tunnel, as for the middle of the air. Then he couldn't help himself and fell sharply. Fortunately, he had been prepared for a long time, and immediately launched the Jizo Tribulation, causing a local low-gravity area, directly canceling most of this falling force, and landing lightly and safely.

With both feet on the ground, Cheng Li immediately stabilized his body and stood firmly. He looked up at the southeast and northwest, and found that he had entered the huge cave under Yongzhou City again.

However, the cave was extremely vast and wide, and Cheng Li's current position was completely different from the position he had entered the cave before. And the soldering iron-headed poisonous snake that led the way for him before has long been missing. Without the guide, it's not so easy to find the right exit.

Cheng Li shook his head, not thinking about how to get back to the ground for the time being. Looking up at the tunnel where he came out, he couldn't help but feel emotional.

There are no less than 1,000 tunnels in the cave. Some are naturally formed, while others are artificially excavated. Some can get through, while others are dead. The tunnel I passed just now was one of the dead ends. Even at the end, there are only rocks and dirt all around, and it is impossible to step on the ground through it.

However, the way of the world is made by man. Even if it doesn't work, you can force it to work. Just like this tunnel. Xiaoqing and Bodhisattva Man dug out a passage of about a zhang and connected it with the old tunnel. In the absence of a way out, a new way of life was forcibly opened. It really teaches people and can't help but admire it.

However, without the assistance of tools, it is difficult and heavy to dig a tunnel more than a foot deep with both hands, which can be imagined.

Especially considering that Xiaoqing and Bodhisattva Man had been in contact with the sect leader before, maybe they were injured. Then digging a way to escape will definitely make their state even worse. If they want to go back to Yongzhou City through this cave again, they may not still have the physical strength.

Therefore, the best choice for the two of them is to hide somewhere in this cave and recuperate for a while. After waiting for the recovery of strength, he will go back to Yongzhou to join Cheng Li and Li Yanzhou. Merely......

Is this cave really that safe? Don't forget, the patron saint who attacked Cheng Li before escaped into this cave through the tunnels in the temple. So far, no trace of him has been found. If this Patronus happens to collide with Xiaoqing and the others, then the situation will be very dangerous.

Cheng Li's expression was solemn, and he raised his hands to act as a human radar again. But before he could gather enough dark matter again, suddenly, behind a stalagmite not far away, there seemed to be a sound of "da~".

It's not loud. But in this silent cavern, the slightest sound will be amplified many times over. In an instant, Cheng Li's heart moved, and the arms that were originally going to be pushed outward were pulled back instead. A large amount of dark matter rolled upside down, covering the whole body in an instant, making Cheng Li "disappear" into the air again.

Just after the invisibility, after the stalagmite, five figures walked out.

The leader was dressed as a Miao man and wore a sleeveless vest. On the muscles of the arms, there are all kinds of colorful tattoos. The pattern is so strange that you can't tell what it is. On his forehead was a red cloth ribbon with various strange symbols. The face was blue and purple, and there were several knife marks, crisscrossing the entire face. At first glance, it makes people feel that he is full of evil spirits, and he is obviously not a good type.

The four people who followed behind the man were dressed in the same way. It's just that the tattoos on their arms are not weird patterns, but hideous-looking ghosts. But their evil aura is far less intense than that of the leader. It seems that there are big differences in each other's cultivation.

"Uh-huh~"

The man, who was full of evil spirits, stood still and breathed comfortably. said: "It's fine at night, but during the day, the sun is too fierce, the sun is uncomfortable, and it's awkward to do anything." It's best to come back here to feel the most comfortable. Mountain spirits, snow charms, fire spirits, water spirits. You say don't you?"

The four men clasped their fists at the same time and agreed in unison, "Master is absolutely right. ”

The evil man waved his hand: "Since it's comfortable, then work hard for me." Later, if you find a spy, you are not allowed to steal and play tricks. Otherwise, hmph, Lao Tzu plucked your skin. ”

The four of them were sincerely frightened, and said in a loud voice: "Don't dare." But Master, did that spy really escape here? It's so big underground here, it's not so easy to find just two people. Otherwise, notify the other brothers in the sect and come in and search together?"

The evil man snorted disdainfully: "Fart! If you call the others over, won't you forcibly divide the credit that should be my monopoly? If you want to find two spies, why bother looking for outsiders? As long as you have them, it is enough. ”

Before the words fell, the evil man suddenly shouted, clapped his palms together, sat on the horse with a heavy waist, his eyes were half-closed, and there were words in his mouth. His right foot was like a cramp, trampling the ground back and forth. Such a strange posture couldn't help but make Cheng Li next to him look inexplicable. But at this point......

"Whew~"

The cold wind blows, and the yin air is awe-inspiring. In an instant, there were miserable green ghost fires everywhere, swaying and rising into the air, and then they were even more like a hundred birds returning to their nests, scrambling to gather towards the evil man. Finally condensed into a ...... in mid-air

A miserable green grimace with distorted facial features!
