After a brief search of the corpses on the ground, everyone had a general understanding of this secret base.

The zombies here cover elites from all walks of life under the complete social system during their lifetimes.

With so many elites from all walks of life gathered together, discerning people also knew that this must be purposeful, but Song Ziyu couldn't guess what they wanted to do.

After the battle, the people continued to move forward in search of a way out.

The series of accidents made everyone realize that this place was not safe, so the next action was more cautious.

Along the way, both sides maintained an open defensive formation, trying to cover each other to avoid encountering a sudden crisis.

Finally, after killing dozens of ordinary zombies, everyone ensured the safety of the entire environment on the second floor.

"There's something wrong with these zombies!" Chen Tianxing observed the zombies on the ground and spoke.

As a five-star hunter, Chen Tianxing has his own unique understanding of the zombie evolution system.

"What's the problem?" Xu Yingnan asked.

"Look at the teeth of these zombies......" Chen Tianxing broke open the mouth of a zombie, revealing a mouth full of fangs.

"I don't see anything wrong." Xu Yingnan's face was full of question marks.

"You little idiot, have you forgotten all the lessons taught at the Hunter School?" Chen Tianxing scolded.

Xu Yingnan sneered and said, "I'm sorry, I deserted during class." ”

"Let's have fun, little cabbage." Chen Tianxing was a little speechless.

Sometimes, there is indeed not much tacit understanding between the top students and the scumbags.

At this time, Tang Jian took a closer look and said with a puzzled face: "This is 'baby teeth'?" ”

Chen Tianxing nodded and said, "Old Tang, you are an understanding person. ”

Song Ziyu was also interested, so he asked, "What are baby teeth?" ”

Chen Tianxing explained: "Everyone knows that zombies will mutate, and the biggest mutation is to change teeth. ”

"Change your teeth!" Song Ziyu disagreed, don't people have to change their teeth.

"Unlike people, every time a zombie changes its teeth, it means that it has taken another step forward on the road of mutation." Tang Jian seemed to see Song Ziyu's disapproval, so he explained.

"Human beings are different, after human beings get rid of baby teeth, a tooth will be used for a lifetime, and there is no possibility of regrowth after it is lost."

"But zombies are different, zombies can mutate many times!"

"Every time you take a step forward on the path of evolution, the zombie's teeth will be replaced accordingly."

"In other words, the more zombies change their teeth, the more elusive the characteristics of disorderly evolution become."

Speaking of this, Tang Jian changed his words and said: "But these zombies are different, their teeth are all baby teeth!" ”

"In other words, after they transformed into zombies, they didn't get any chance to mutate." Chen Tianxing added.

"What does this mean?" Song Ziyu asked.

Chen Tianxing looked at Song Ziyu like an idiot and said, "You have to know that the outside world has been ravaged by the corpse tide for hundreds of years!" Which zombie hasn't mutated? You won't even find zombies that aren't mutated! ”

Hearing this, Song Ziyu was shocked and realized that things were not simple, but he couldn't think of anything that was not simple!

"You mean, these zombies in front of you are freshly baked?" Song Ziyu asked.

"That's not right!" Tang Jian denied: "It's true that these zombies have not mutated and evolved, but the age of death is definitely a long time ago, you can see that the skin on their bodies has almost no moisture, which is a characteristic of natural air drying." ”

Chen Tianxing also muttered: "These zombies seem to lack the factor of mutation...... It's weird. ”

Suddenly, Chen Tianxing became irritable.

"Oh, no research, I'm not a scientist, how do I know so much." Chen Tianxing slowly stood up and said, "If the matter here is handed over to the Federation, they may be able to organize a project research team for this purpose, but we ...... Forget it, let's find a way. ”

The group continued to walk, passed through the second floor, and found the elevator again.

This time, everyone held their breath and lit up the elevator button on the negative third floor with apprehension.

No one knows what awaits you.

The elevator goes down to the third floor, and there is no danger happening, and you are greeted by a living area.

Self-circulating waters and vegetation, dense greenery envelop the entire space.

"This ......"

Seeing this scene, Ma Senming was stunned!

"The plants and soil here are not polluted!" Ma Senming exclaimed.

For Masenming, this is nothing less than a treasure trove.

Song Ziyu didn't feel so much, just looked around curiously, this is a botanical garden formed by ultraviolet rays simulating sunlight...... Or rather, the farm.

This kind of self-sufficient Eden-like conception is not uncommon in human social experiments, so Song Ziyu didn't take it seriously.

At this time, Song Ziyu was quite interested in the fruit tree in front of him.

It is an apple-like fruit tree.

The branches of the fruit trees are luxuriant, and the fruits are hanging from the branches!

Song Ziyu reached out and picked a fruit, took it to his nose and sniffed it.

Well...... There is the fragrance of apples.

"Level 2 Authority Manager, your actions have violated the dungeon management regulations, and five contribution points will be deducted." A pleasant voice sounded, startling everyone.

Everyone was taken aback, and they all raised their guns to look at the green forest around them.

"Who? Come out for me! Song Ziyu shouted, and then looked vigilantly in the direction where the voice came from.

The environment here is complex, and it is very likely that potential threats are hidden!

Awkward silence......

Tang Jian and Xu Yingnan's faces were ugly, because the enemy had obviously avoided everyone's attention, which made everyone as hunters very shameless.

"Where is the enemy? An Tong? Xu Yingnan asked.

Little Lori looked around nervously, and said with a crying voice: "I can't feel ......"

At this time, Song Ziyu discovered a frightened scene!

A little girl wearing a plaid shirt and school uniform, combing short hair, and thin light bangs appeared in the center of the crowd!

That's right!

She's standing right in the middle of the crowd!
