While Su Lifeng was walking underground with the old woman, Sishui and others were still fighting fiercely with the alien population above.

Suddenly, Hongye's movement paused for a moment. She looked around and kicked a alien species that was pounced on her for a dozen meters away, then turned around and rushed into the grass.

Cheng Xiaomei noticed this scene and turned around and shouted twice, but failed to stop Hongye's petite figure from disappearing into the tall weeds with unusually agility speed.

"What's this for?" Cheng Xiaomei muttered in confusion.

However, after getting along during this period, she has accepted the difference between these two non-human and normal human aliens like her. They basically do things that are not normal. Moreover, her running has also led many aliens to chase her, which makes Cheng Xiaomei, who is closer to her, suddenly feels lighter in pressure.

"Forget it." Cheng Xiaomei focused her attention on the battle again.

When she used a machine gun before, she was pursuing the moment she pulled the trigger, and the sense of determination that she already knew the result in her heart.

There is no need to deliberately aim, and the moment she raises the gun, she knows that she will hit the target.

This feeling can not be achieved by practicing on the shooting range, but is slowly mastered by constantly shooting and killing yourself.

Cheng Xiaomei also had to admit that many of Su Lifeng's theories were correct, even if they were just talking casually.

For example, he said that the birth and evolution of human mutants is to fight against alien species, and their appearance is to kill.

When Cheng Xiaomei grasped this feeling, she understood the meaning of this sentence.

Mutants are indeed born for killing and fighting. Otherwise, they would not have such combat intuition, nor would they have experienced the pleasure of fighting so deeply.

When she pulled the trigger, the bullet shot out from the muzzle, and a dazzling blood burst out from the target's body... Cheng Xiaomei didn't know what others were like. But she did feel that with her personality, she would feel that it was actually quite pleasant at this moment, which was an incredible thing. She accidentally stepped on a bug to death and would be so scared that she didn't dare to look at the corpse!

Therefore, many mutants become cruel and bloody. It is not only because of the high survival pressure, but also because of this sense of pleasure.

Put down the machine gun and fight with her body. At first, Cheng Xiaomei was a little scared, but when the first alien species was entangled by her arm after being mutated like a python, then it was deeply pricked into her body by countless spikes, and then it was quickly thorned into rotten flesh while she twisted, Cheng Xiaomei felt a stronger killing pleasure than using a weapon.

This feeling of fighting with your own evolutionary body can make people feel the attractiveness of evolution!

And at this time, it's underground...

Su Lifeng followed the old woman alien and slowly moved forward along the uneven underground passage.

He was not too worried about Cheng Xiaomei and the others. In fact, if there was any danger, Sishui, the hidden biochemical nuclear bomb, was not a vegetarian.

Of course, this "nuclear bomb" is still in its growth stage.

There was a dead silence underground, with only two people's footsteps coming and going.

At first, Su Lifeng thought that the soil above his head was purely supported by thickness, but gradually, Su Lifeng found that the grassroots above his head were densely covered with grass roots.

It is these entangled grassroots that form a "ceiling" like a net that opens up such a space for the underground.

Only then did Zu Lifeng suddenly realize that after the triple baptism of climate change, plant mutation, and war, the ecological environment and landform structure on the earth are actually undergoing rapid changes.

What I see now is like an underground nest. It is definitely not an exception.

"You guys want to hit the safe city directly through the underground, right?" Su Lifeng suddenly asked vigilantly.

The old woman smiled hoarsely and replied, "How is this possible? Human military has been built underground. There are also special awakeners who always respond. You are not a member of the army at first glance."

"..." He was actually ridiculed.

I still use this sentence "You are not a city man when you see it."

Su Lifeng once again suppressed the urge to kill this dead old woman immediately... Anyway, he was not in a hurry.

"It's almost here." The old woman ignored the murderous aura coming from behind and suddenly stopped.

Su Lifeng looked at a wall ahead in amazement.

To be precise, half a wall.

It was obviously also taken care of by bombs, and the original terrain could only be vaguely seen...

"Reservoir?" asked Su Lifeng.

"You, a human, should be clearer than me. I can't tell the complex things about you humans. Although I am not an old man, I have absorbed the skin of an old man and the memories I have obtained are also from Alzheimer's disease. Don't you think you should take care of such an old man?" the old woman said seriously.

Su Lifeng glared at it: "You won't even let Alzheimer's disease go?"

"Indeed, when hunting, we always choose the weakest prey. We alien species start with the elites among you humans, but there are exceptions. What's more, this is a very good protective color." The old woman alien species said.

"What did you bring me here for?" Su Lifeng had no time to listen to it nonsense. He interrupted it and asked. He had a vague premonition in his heart, but he felt that the answer was really...unbelievable.

"Aren't you going to the Safety City? You can quickly pass through our encirclement along here. As for how to pass through the human blockade line in the future, I think you must have a solution, right? It's not my business, I can only help you get here." The old woman said alien.

It was indeed incredible! Even if it heard it say it in person!

Su Lifeng had to ask a very old-fashioned but had to ask: "Why do you want to help me with a good alien species? If you drink too much or your brain will change?"

"Are you worried that I have bad intentions?" the old woman said.

"Do you still have to worry about this? You obviously have bad intentions. I don't walk through the 'peering passage' you left for the safety city, but I just want to walk around the encirclement. Even with your poor IQ, you can think of me as a toe. It's normal for you to help us in this situation, but what I wonder is how you restrain you from swallowing you? Between helping us and eating us, you should choose the latter as a alien species without thinking, right? This is your biological instinct."

"Unless, you have a reason to be even worse than having bad intentions." Zuli Feng said.
