Wei Yi looked at the entrance of the cave and just wanted to walk over, but was stopped by Meng Youcai on the side hurriedly waving his hand.

Wei Yi was stunned, and when he was about to ask what was going on, Meng Youcai whispered to him: "Don't worry, this one is not the entrance." It's just a pretense. Calm down. ”

Wei Yi was stunned. But before he could understand, he saw Xiao Tie take out the card and quickly walk to the crooked neck tree on the other side. With a quick movement, he inserted the card into the tree again.

This time, there was no sound. But to Wei Yi's surprise, not long after Xiao Tie inserted the card, the entrance quickly disappeared underground.

Soon, another hole appeared quietly and silently in front of Wei Yi and the others. This time, the hole was noticeably narrower than the one just now.

Meng Youcai turned sideways and said to Wei Yi: "Don't worry, this is not either." A real entrance, with another organ. ”

Just as Meng Youcai was explaining to Wei Yi, Xiao Tie walked quickly to the entrance of the cave, leaned over and touched a certain place at the entrance of the cave.

There was a crisp "click". When Wei Yi saw it, not far from them, he suddenly opened a hole again. This time, the hole is slightly wider, enough to accommodate two people entering and exiting at the same time.

Xiao Tie said loudly to everyone: "Quick, go in immediately." ”

Meng Youcai pulled Wei Yi and said quickly: "Head, quick, come in with us." Be careful. There are also mechanisms in it. ”

Wei Yi nodded stunnedly. He followed the crowd in. As soon as they entered, the hole behind them quickly disappeared.

Wei Yi didn't expect this place to be so secretive. Even the entrance is so well designed.

He was glad he hadn't come alone recklessly. If you're not careful, you're really doomed.

But at the same time, he thought of Li Mingyu again. Now, I don't know where his eldest brother went? Will he really know about such a secret place?

Thinking of this, Wei Yi began to pray secretly again. He really hopes that his eldest brother doesn't know about this place. Such a strange place must be extremely dangerous.

He was worried that if Li Mingyu broke in recklessly, if he fell here, he would really not be able to save it.

"Head, what do you want? Be attentive! Meng Youcai's sudden voice instantly interrupted Wei Yi's thoughts.

Wei Yi hurriedly looked around, only to realize that he had unknowingly followed them deep into the tunnel. He was thinking about Li Mingyu's possible whereabouts just now, and he didn't check for a while, and almost took a wrong step.

Wei Yi hurriedly apologized: "I'm sorry, I thought of something just now." Distracted. Are we there now? ”

Xiao Tie glanced at Wei Yi and whispered: "Meng Youcai, you take him carefully, this road is full of organs." In case he gets distracted and goes wrong. If we touch the mechanism, then we will all have to die here. ”

Meng Youcai nodded and moved closer to Wei Yi. The corners of Wei Yi's mouth twitched, and he told them with some regret that he had just been distracted.

Wei Yi looked around. When he entered the cave just now, he didn't pay attention to the situation around him, and at this time, it seemed that the surroundings were gloomy and full of Xiao Killing.

With a "whew", a cold wind slowly blew over. Before the wind reached Wei Wei's side, Wei Wei felt a biting chill.

"Hold your breath, there's psychedelics in this wind." As soon as Meng Youcai saw the wind, he hurriedly reminded in a low voice next to Wei Yi.

Wei Yu hurriedly took a deep breath and held his breath.

"Whew, whew" The wind slowly blew through Wei Yi's body with a sound that asthma patients often make. Wei Yi only felt a chill that was cold to the bone marrow, and wrapped himself from head to toe.

But he kept Meng Youcai's warning in mind and stood motionless, not daring to relax at all.

After a few moments, the wind slowly dissipated. Just as Wei Yi secretly breathed a sigh of relief and wanted to open his mouth to breathe, Meng Youcai suddenly shook his hand desperately towards him.

Wei Yi was shocked, hurriedly closed his mouth, and covered his nose with his hand. He held his breath again and stood still.

After a long time, Wei Yi got a hint that Meng Youcai could breathe. He hurriedly opened his mouth and began to breathe heavily.

Wei Yi looked sideways at Meng Youcai, lowered his voice and asked, "Why can't you ventilate just now?" Didn't the wind pass? ”

Meng Youcai pointed to the ground and said, "The wind is not the key, the key is what is under your feet." ”

Wei Yi looked down. By the dim light, he realized that there was a thick layer of dust under his feet. The dust, gray in color, was very strange.

Wei Yi pointed to the dust on the ground and asked, "This?" Isn't this just dirt? ”

Xiao Tie glanced back at Wei Yi and said to the people behind him, "You guys pay more attention." Head, he doesn't know anything about us. You all take care of him. Don't be surprised. Gone, all followed. ”

As he spoke, he took a step and walked slowly.

Meng Youcai took a cautious step, and whispered to Wei Yu as he walked, "Head, you don't know. This soil is mixed with things. As soon as the wind blew just now, if people who didn't know about it would be guilty if they sucked the things in the soil into it. ”

Wei Yi was stunned, and asked as he walked, "Mixed with things?" What's adulterated? ”

Meng Youcai pointed to the ground and said, "It's psychedelics." This thing is a powder, colorless and odorless. When the portion size is large, it looks like white ash. But as soon as it is diluted, there is no color. It is not deadly, but it is dangerous and can give people terrible hallucinations. ”

When Wei Yi heard this, he suddenly thought of the strange hallucination that he and Situ Nan had had. He hurriedly asked again, "What kind of hallucination does this thing give people?" How scary is it? ”

Meng Youcai shook his head and said, "I haven't tried. They told us when we were training before. I've heard that if you inhale a large enough amount, you can keep you unconscious. But I always thought that I was still awake in my head, and there would be a lot of weird hallucinations. ”

"Including your friends suddenly sneaking up on you?" Wei Yi suddenly asked without a clue.

Meng Youcai was stunned for a moment, nodded and said, "There is such a possibility." How? Head, have you tried? ”

Wei Yi shook his head. Although he was not completely sure that he had been infected with this psychedelic drug in the first place, he vaguely guessed that this matter might really be done by Gongsun Jiu as Nangong Ruo had deduced at the beginning.

Thinking of Nangong Ruo, Wei Wei's heart became uncontrollably sad again. That eight-faced, clever and intelligent man disappeared so suddenly. A sad emotion slowly crept into Wei Mi's heart.

Meng Youcai noticed Wei Yi's sudden change in mood. He asked in a whisper, "Head, what's wrong with you?" ”

Wei Yi shook his head and said slowly: "It's nothing, I suddenly thought of a good friend." He's no longer there. ”

When Meng Youcai heard it, he didn't know how to persuade him. He was silent for a moment, then reached out and patted Wei Yi's shoulder, and said, "People always die, don't be too sad." If your friend is still around, he doesn't want to see you like that. ”

Wei Yi smiled faintly at him and said no more. He bowed his head and followed the group of people, walking slowly forward.

Meng Youcai looked at Wei Yi's somewhat sad back and shook his head slightly. He turned around and glanced at the few people behind him, and then quickly caught up with Wei Yi. Here, there are many organs, and it is better for Wei Yi to be responsible for Wei Yi's safety in person.

Handed over to others, his heart still can't be completely reassured. His entire net worth and the safety of his old mother are now counting on Wei Yi.

Wei Yi followed these people, stopping and stopping all the way. From time to time, I have to take a few steps back, and then a few more steps diagonally. The people around Wei Yi reminded Wei Yi from time to time where to go and where not to go.

Wei Yi listened to them one by one in his ears and remembered them in his heart. He looked closely at the ground. After looking at it for a long time, I suddenly realized that the ground was actually made of extremely small stones one after another.

The stones, the same size, were arranged in a neat and orderly manner. Where they fit together, they fit together. If Wei Yu hadn't looked carefully, it would have been really difficult to notice.

He thought carefully about the route they had taken, and realized that they were constantly walking in the shape of the number eight.

In the following journey, Wei Yi's discovery was once again confirmed. Wei Yi found that they really followed this number. He was secretly happy. In this way, he has mastered the rules of entering and exiting here. Once something happens, he can enter and leave this place on his own, and he doesn't have to pretend to be someone else.

"Wait a minute." Just as Wei Yi lowered his head to study the walking route, Xiao Tie suddenly stopped.

He stopped the crowd and walked quickly to the side of the wall. Wei Yi saw that he stretched out his hand and kept groping around the wall, tapping it from time to time.

Wei Yi tilted his head and asked suspiciously, "What is he doing?" Why don't you go? ”

Meng Youcai, who was beside Wei Yi, quickly returned: "If you go any further, you can't go." This road is here, and it is the end. ”

Wei Yi was stunned and asked, "Is this road coming to an end?" So, we're already there? ”

Meng Youcai shook his head and said, "No." That research lab is actually in Yecheng City. This is a secret path. We can only enter and exit when we are on a mission. There is still a long way to go from Yecheng. ”

When Wei Yi heard this, it became even more strange. He asked suspiciously, "Since you haven't arrived yet, why don't you leave?" Is it wrong to go any further? ”

Meng Youcai nodded approvingly and said, "That's right." When the road reaches here, it is the end. If you go any further, you will be sent to death. Xiao Tie was now looking for the entrance to another road. ”

Wei Yi suddenly realized. He raised his eyes and carefully looked at the endless passage ahead, and said slowly: "The person who designed this secret passage is really thoughtful enough. In this way, the truth is true and false, the false and the true are one ring after another, and those who don't know are really coming and going. ”

Meng Youcai said approvingly: "Isn't it." Over the years, there have been many people who have come to investigate this laboratory, but they have all come and gone. That's why, over the years, this place has been so stable and nothing has happened. ”

At this point in their conversation, Xiao Tie finally found the location of the mechanism on the wall. He gently pulled out a stone and reached out and pulled inside.

"Tie, tie"

The sound of rocks rolling and the sound of machinery turning at the same time rang out.

Wei Yi raised his eyes and stared at the wall in front of Xiao Tie. In just a moment's effort, the originally smooth and seamless rock wall slowly parted to the left and right, revealing a portal.
