I started with a seed, luckily I have probability glasses

The experimental subjects who were originally walking slowly and evenly outside suddenly rushed towards the metal pipe leading to Liangcheng like crazy as if they had been injected with chicken blood.

The speed of those super biochemical experimental subjects at the bottom of the pit was even faster, as fast as arrows released from a bowstring. They leaped up from the bottom of the pit and then disappeared into the metal pipe in the blink of an eye.

There is no doubt that they have forgotten each other and started to act.

Bang, bang, whoosh whoosh whoosh…

However, what disappointed Li Chuan was that only about half of the super biochemical experimental subjects in the deep pit left and then stopped. The remaining experimental subjects were no longer agitated and slowly returned to their previous rhythm.

It seems that being able to draw out these experimental subjects is already the upper limit of a city ruin.

Li Chuan calmed himself down and turned to look at Yuan Feifei who was muttering constantly.

"I can do it, I can do it, I will definitely complete the task successfully, it's okay, it's okay!"

Just as Yuan Feifei was cheering herself up in her heart, Li Chuan's dull voice suddenly came from the side.

"Get ready, we're about to jump."

Yuan Feifei was shocked, she couldn't believe it.

“Jump down!?”

Li Chuan nodded.

"That's right. We have no choice but to jump. We can't climb down with the control we have over this body."

Yuan Feifei nervously followed Li Chuan to the edge of the pit.

"Um, I, wait a minute, I'm a little bit stupid!"

Before she could finish her words, Li Chuan dragged her down into the deep pit in front of them.

Bang, bang!

The density of experimental subjects was much lower, but at the bottom of the deep pit, which was still extremely terrifying, two insignificant experimental subjects fell from the top of the pit. Although they made some noise, it was nothing compared to the noisy environment.

Li Chuan controlled the huge body of the experimental subject and slowly climbed up.

"Are you okay? If you are, don't use healing skills. Use Zhang Heng's potion."

Yuan Feifei's voice sounded dull but trembling.

"It's okay, it's okay. I was just a little afraid of heights. I'm okay now."

Li Chuan couldn't help but feel confused when he heard her say that she was afraid of heights.

"Can't you fly? Why are you afraid of heights?"

Yuan Feifei told the truth.

"Then I must be afraid of falling from heights."

This girl is quite good at self-analysis.

"Follow me, walk along the wall, and don't get too close to those giants and super experiments."

Yuan Feifei, who had regained her ability to move, struggled to get up.

"Okay, I understand, President."

The two of them walked along the edge of the pit wall, passing through the gaps between the experimental subjects. Their goal was the colorful door opposite with a stick figure pattern on it.

It was on the way to the bottom of the pit that Li Chuan saw clearly the source of these experimental subjects.

At the bottom edge of the pit, in addition to the brown gravel ground, there is a circular sand pool with a diameter of three to five meters every ten meters or so.

I can't be sure it's sand, but the tiny yellow particles that keep surging like spring water really look like sand.

ho.

Li Chuan watched helplessly as a severely decayed human head emerged from the rolling sand.

Then the shoulders, and finally the torso.

An intermediate-level biochemical experimental subject crawled out in front of Li Chuan in a very lively manner.

I thought that this final experimental base in the bottom area was the birthplace of all biochemical experimental subjects, but I didn’t expect that this was not the place. The real birthplace was in an unknown location under the sand.

Eh?

Li Chuan suddenly stopped.

birthplace?

His mind subconsciously recalled the contents of Secret 2.

Secret 2: Although we are buried in different places, at least we came here together.

The word "buried bones" is quite appropriate for the atmosphere here, and all the experimental subjects are born from these sand pits. Could it be that the clues to the main task are hidden in this sand pit?

When Yuan Feifei saw Li Chuan suddenly stop, she also hurriedly stopped. When she was about to ask Li Chuan why he stopped, she suddenly saw Li Chuan squeeze a low-level zombie into the sand pit next to him that was constantly surging.

The zombie that suddenly fell into the sand pit fell into the sand pit at a loss. After being confused for a while, it stood up from the sand pit and continued to wander aimlessly into the distance.

Seeing this situation, Li Chuan had no choice but to continue moving forward.

This sand pool is one-way. The subjects inside can climb out, but those who have already climbed out cannot go back in.

So if you want to explore under the sand pit, you can't do it from here.

Not far away, an obese super biochemical experimental subject suddenly stopped eating the giant's flesh and blood, and with a trembling body, it turned its eyeless face to the two motionless experimental subjects not far away.

It was not until the two experimental subjects moved again that it continued to lower its head and gnaw on the flesh and blood of the giant beneath it.

Li Chuan and his companion passed through the endless horde of zombies and finally arrived at the door after spending a lot of time.

Just as Li Chuan and the other person were standing in front of the door, the fat super experimental subject raised his head again and turned towards the direction of Li Chuan and the other person.

Roar, roar, roar.

This super-life experiment began to make a low and rapid roar, and then jumped off the body of the chaotic giant and began to walk towards the gate curiously.

The two people who were looking for the keyhole on the door at this time were unaware of this.

"I saw the President! I saw the keyhole."

Li Chuan, who had been searching for a long time without any results, said in surprise.

"Where?"

Yuan Feifei pointed with her arm at a place more than one meter above their heads.

"There! That little black hole on top of me should be it."

Li Chuan quickly looked up.

Sure enough! There was a small rectangular hole in the direction of Yuan Feifei's finger.

"Damn it! How can it be so high up?"

Yuan Feifei said hurriedly.

"It's okay, President. I can fly up."

Li Chuan hurriedly stopped him.

"Don't fly! Using skills will use up mana, and mana will draw energy around you. It would be bad if that energy touched those super experimental subjects."

Yuan Feifei was secretly anxious.

"So what should we do now? Find something to cushion the two of us?"

Li Chuan was about to answer when Arnold's voice suddenly sounded in his mind.

"Master Li Chuan, there is a 'super experimental subject' approaching behind you."

When Li Chuan heard this, his whole body trembled, and beads of cold sweat instantly appeared on his forehead.

Just as I was about to turn around, I heard Arnold continue,

"Don't turn around. It's moving very slowly, as if it's observing. If you turn around, it's likely to pounce on you in an instant."

Li Chuan's heart beat faster and faster, and he quickly asked himself in his mind.

"Can you see who it's targeting? Me or her?"

Arnold's voice was uncertain.

"It should be you."

Li Chuan hurriedly walked to the side and sent a message in the guild channel at the same time.

"Fly up and open that door, quick! There's a monster targeting me, I'm going to lure it away first!"

Now we can’t worry about the immeasurable energy. If we have been noticed by this monster with a certain degree of intelligence, there will be no time to make more preparations and we can only fight quickly and decisively!
