"But..." Professor Liu's mood was still depressed, "Where can they go?"

We know that the caves are surrounded by big trees. If they leave their attack range, they will escape from the cave area.

There is no one on the trees or on the ground at the moment, and they are as if they have disappeared out of thin air.

But according to my experience, no matter how bizarre things seem, there must be a reason behind it.

It's like magic, it looks incredible, but there's always a trick, it's just hidden by the magician.

Professor Liu was determined to protect his two students, but now the two disappeared together. He was panicked for a moment and we cannot expect him to make rational judgments.

Chen Qinghan borrowed Professor Liu's shovel. He began to dig down from the place where his footprints disappeared, shoveling off a layer of soil on the surface, and a flat stone road was exposed below.

The road to the ‘Downtown’ is not broken, and you can continue to move forward. This should not be the end of this trip.

Chen Qinghan checked the ground around the footprints again. There were no roads in the jungle, and there were wildly growing plants everywhere. There were strange flowers and plants growing on the ground, which were weird but also beautiful.

If someone passes by, they will definitely step on them. Chen Qinghan said he just wanted to confirm whether there were any other 'vanishing points'.

"A dangerous area of ​​five kilometers." Professor Liu suddenly spoke.

"Well, it's like a mechanism, every five kilometers, change it." Chen Qinghan understood what Professor Liu meant and 'translated' it in a way that I could understand.

Professor Liu means that the entire island is a circle, and the jungle is filled with invisible boundaries of areas, which protect the area in the center of the island in the form of a circle.

The species of animals and plants in each ring are different, and it may be to avoid them killing each other, so there is a safe area between the ring area.

In fact, as long as you master the characteristics of all animals and plants, let them grow and reproduce according to their own wishes, and form their own ecological chains.

But that will be a big project, and there are too many variables in the process and it is difficult to control unless someone guards and keeps correcting.

or……

I looked at the stone road dug by Chen Qinghan and remembered the non-corrosion bridge on the underground river.

"Xiao Fu, try it." Chen Qinghan stretched out his index finger and gestured in a circle, meaning around.

He knew my skills very well, and asked me to try it out to see if I could ‘heard’ any news.

The jungle is dense, and there are many small animals, but there is no special sound.

Why are there no large beasts on the island? I realized this problem only then.

Even if there are no tigers, bears, wolves, or wild boars, there should be some, right?

I shook my head gently. Chen Qinghan was not disappointed. He couldn't find care and Cong Zhibo. Professor Liu would not leave. Although Lu Xiaodao didn't say anything, he had no intention of leaving.

He needed Meng Qingyu's antidote, probably because he wanted to find her.

I don't care. Just dig Bishi and He Sudi, I don't want to find them.

Professor Liu has already told me how to leave the sea of ​​shipwrecks. In fact, I can pull Chen Qinghan away now.

But now it is a bit unauthorized to leave. Since I promised Professor Liu to help him bring things out, at least I have to go to the destination and see the situation before talking about it.

Moreover, Chen Qinghan would not give up saving people just now, and it was impossible for others to leave when they were still alive and dead.

When Professor Liu's emotions calmed down slightly, he and Chen Qinghan discussed the possibility of everyone missing.

I squatted aside and listened, but as I listened, I became sleepy, and had no place to sleep in the jungle, or there was no safe place to sleep.

I could only resist sleepiness and accidentally saw Lu Xiaodao prying the bark of a tree with a flying knife.

"What are you doing?" I walked over and wanted to see if he had noticed it.

"Look for something." Although Lu Xiaodao talks little, he will not ignore others. As long as you take the initiative to talk to him, even if there is a word or a syllable, he will always reply.

"Be careful." The trees in the jungle are more ferocious than lions and tigers. It is quite dangerous for him to peel the bark there.

"Yes." Lu Xiaodao responded and continued to use his knife to cut the tree.

I don’t want to listen to the “reasoning” of Chen Qinghan and Professor Liu. They were repeatedly pondering the details of Meng Qingyu and others’ disappearances, and it felt like they were recording a mystery novel, which made me sleepy.

So I squatted to Lu Xiaodao and watched him pluck the bark. He dug a small hole on the trunk, and transparent sap seeped out from it.

He dipped a little branch and put it under his nose to smell it. I didn't make a sound next to him, just watching him do these things, like observing the tomb robbers who were tinkering with the mechanism in the tomb.

He took out two black grass leaves and a colorful mushroom from his arms, stuffed them into a pit on the tree, crushed them with a knife, and mixed them with the sap.

"Anti-drug." He whispered, "try."

After saying that, I lowered my head and sucked the unknown liquid in the tree pit. I widened my eyes in surprise, for nothing else, just for his courage.

He said he wanted to try it, which meant that he was not sure whether this thing was the antidote. The black grass leaves and colorful mushrooms seemed to be poisonous. He dared to put his mouth directly. If he sipped, he might die!

"What are you doing?" Professor Liu noticed his actions, but when he stepped over, Lu Xiaodao had already swallowed the 'anti-drug'.

"He wants to try the antidote." I finished speaking for Lu Xiaodao, and automatically took two steps back to make room for Professor Liu.

Professor Liu approached the tree pit and saw the pile of suspected toxic "ingredients", his face turned as dark as the bottom of the pot.

"Who told you to try it randomly? You're desperate!" Professor Liu waved his arms excitedly, and his stable emotions broke out again.

"It's okay." Lu Xiaodao's reaction was in sharp contrast with Professor Liu. He seemed to have no concern for his life and death.

I have seen many people's eyes when facing death, including Lu Xiaodao, who is indifferent to life and death, and has empty eyes.

Life or death is not the most important thing to them, or even the least important thing.

In this case, why did he use himself to experiment and try the antidote?

"Do you want Yaoyao to become an orphan?" Professor Liu grabbed Lu Xiaodao's collar and swayed him back and forth, tears flashing in his eyes.

Lu Xiaodao still looked expressionless, like an ignorant wooden man.

Professor Liu was so angry that he pushed him. Fortunately, Chen Qinghan came over to prepare to pull the frame and caught Lu Xiaodao who was falling straight backwards.

Teaching Liu realized something was wrong and hurriedly asked Lu Xiaodao what was wrong, but Lu Xiaodao did not respond.

Chen Qinghan checked his eyes and pulse, and his eyes didn't blink, as if they were frozen.
