"No, we're not going to die." Ding Xiu's voice was firm and powerful.

He fell to the ground and lifted an iron lid with all his might, revealing a bottomless hole underneath.

Chen Jianing shone the light into the entrance of the cave and found that an iron ladder extended from there.

"You go down first, I'll cover you." Ding Xiu carried a piece of steel bar that had been pulled out of the crack in the stone and rushed towards the zombies behind him.

Chen Jianing's figure disappeared at the entrance of the cave, Ding Xiu had no worries, let go of his hands and feet to open the bow left and right, and the steel bar instantly knocked several zombies in front of him to the ground.

His attack was fierce and fierce, but he couldn't kill those monsters.

However, Ding Xiu's ruthless goal was not to kill them, but to buy himself a little more time.

There's still a little space.

The steel bar made an arc circle, sweeping away the figure within a meter in front of him. The knocked down zombie tripped over its companion behind it, and the speed at which the corpse squeezed through was sluggish.

Taking this opportunity, Ding Xiu turned around and drilled into the hole. The moment the iron lid was pulled up, it was full of zombies surrounding it.

Ding Xiu climbed the ladder in the cave with one hand, and stuck the steel bar under the iron cover with the other hand.

It was very deep inside, and the two of them climbed the iron ladder for a while before coming to the bottom.

"What is this place?" Below the ladder is the city's sewer, but the environment here is very unfamiliar to Ding Xiu and Chen Jianing.

There is no such thing in the camp where Ding Xiu lives, and if Chen Jianing, who lives in Brilliant City, does not have this experience, I am afraid that he will never have contact with the sewer in his life.

The light shone around, and several circular passages appeared in front of him, and the passages were pitch black and bottomless.

"Which way?" Chen Jianing was a little dazed.

"Take this path." Ding Xiu chose one of the passages, took the flashlight handed by Chen Jianing, and got into it first.

The space in the passage was relatively narrow, and Chen Jianing followed Ding Xiu to the inside, and was a little cramped when moving forward.

"I remember when you were at the Institute, you said that those zombies weren't ordinary zombies." Ding Xiu recalled the process of fighting the zombies outside, and suddenly asked.

"Yes, I'm sure." The girl behind her nodded, "Your biometric device probably hasn't updated the data in a while, and the information it reported misled me at that time." ”

"How did I mislead you?" Ding Xiu had a hunch that he would encounter those dangerous zombies in the future, so it was imperative to understand their information correctly.

"The biometric identifier still contains the information of the first generation of zombies, but from the situation we have encountered, the zombies in the research institute are far more dangerous than the original generation."

"You mean, zombies mutate?" Ding Xiu was a little dumbfounded, "Aren't they infected with viruses and mutated?" ”

"In the past, zombies didn't mutate, but now, it's clear that they do." Chen Jianing recalled the experience along the way, combined with the analysis of some information that he had seen in a book with miscellaneous content in the school before, and said: "The first generation of zombies appeared when my grandfather was young, and they were human beings infected with the zombie virus. About Zombie Virus...... Well...... This is a long story, but in short, the zombies have mutated like other creatures in the following decades. ”

"How so?" Ding Xiu was still a little unsure, because he preferred to believe the biometric identifier that Chen Jiansen gave him.

"I saw it written in the book." Chen Jianing said, and reminded him a little more: "The weakness of zombies is in the head, but do you remember that when you attacked those zombies, one zombie was pierced through the head by you with a bullet but did not die, but then the other zombie died after you completely smashed the head." ”

"Could it be that the weakness of their heads has been strengthened in evolution?" Ding Xiu was a little surprised, because Chen Jianing's analysis was indeed very reasonable, and he also thought about it in combination with his own feeling of fighting zombies, "Their speed is very fast, and the strength of their bodies has also increased. ”

"Yes, this wasn't the case with zombies in the past." Chen Jianing nodded and said, "I'm not sure to what extent they have mutated, but they are definitely not F-class mutated creatures as the bioidentifier says." ”

The two whispered to each other, and suddenly the light spotted some paintings on the walls inside the passage.

"What are these?" Ding Xiu looked at those strange patterns curiously.

"Street graffiti?" Chen Jianing took a closer look, not quite sure.

"What is street graffiti?" Ding Xiu asked, "Is this a code?" ”

"No, you can think of it as a culture. This culture appeared almost a hundred years ago, when disgruntled people painted such patterns on the streets and walls due to the large gap between the rich and the poor. Chen Jianing told Ding Xiu some of what she knew.

The further the two walked, the more patterns appeared on the walls.

"Strange, why do people who are dissatisfied with society stay in such a place?" The girl thought it was a little strange, because this kind of narrow passage did not seem to her to be a place for people to live at all.

"You also said that some people are dissatisfied because of the gap between the rich and the poor, and for these poor people, this kind of place can at least provide shelter from the wind and rain." It is difficult for a noble girl born in a big city to understand the suffering of the people at the bottom, but Ding Xiu is different, he has seen a lot of cruelty in the world.

Ding Xiu's words made Chen Jianing thoughtful.

The two of them quickly completed this section of the passage, and after jumping out of the opening, there was another passage outside, except that it was square, and the spacing between the left and right sides and up and down was twice as large as the previous circular passage.

There are no two ends in the passage, Chen Jianing does not have a strong sense of direction, and Ding Xiu still has to make up his mind at this time.

"I think we should go this way." Ding Xiu said.

"Why?" Chen Jianing was a little curious, because Ding Xiu made a decision quickly this time.

"It's windy over here."

The presence of wind is generally a sign of an exit to the outside.

The two of them walked in the direction chosen by Ding Xiu, and in the dim passage, the range that the flashlight could illuminate was very small.

As Ding Xiu moved forward, he adjusted the angle of the light from time to time so that he could see more clearly.

The two walked a long way, Chen Jianing held Ding Xiu's clothes, and occasionally looked back behind her for a moment or two, although she followed Ding Xiu, she was still a little scared in her heart.

All the girl's fear came from the darkness behind her.

"Don't be afraid, the road we have come along is safe." Ding Xiu noticed her strangeness and comforted her.

"With so much graffiti on the walls, could there have been many people here before? They ...... now" Chen Jianing's voice was very small, and she said what she was worried about, half because she was nervous, and half because she reminded Ding Xiu.

"At least we didn't see anything all the way." Ding Xiu knew that Chen Jianing was worried that there would be zombies in the passage, and to be honest, he wasn't sure if there was any danger in it, but he could only continue walking, and he had to help the girls around him to eliminate their fear.

His words worked, and Chen Jianing was no longer as apprehensive as before.

"Tell me about the outside world." The quiet environment was very depressing, and Ding Xiu didn't want the girl to fall into uneasiness again soon, so he took the initiative to find a topic.

"The outside world? What are you referring to? Chen Jianing asked.

"Hmm...... Country? Something like the Elbrand Empire. Ding Xiu just wanted to find a topic to divert Chen Jianing's attention, and it didn't matter what he was talking about.

"The Elbrand Empire?" Chen Jianing thought for a while, "After the nuclear war, the original order of the world was broken, the previous countries all died in the war, and the survivors established new ones. For example, our motherland Grells, and the Elbrand Empire you just mentioned. Denzer, Tafleur, and Frantic are also big countries, but there are also some small countries in the world, but the overall number of countries is much smaller than before the nuclear war. ”

"Will we fight them?"

"The war has never stopped, it's just big and small." Chen Jianing's father and grandfather are both high-level officials in the Eastern Military Region, and she knows a thing or two about things on the front line.

"Why fight?" Ding Xiu asked again.

"Why?" Chen Jianing was stunned, thought about it, and said in an uncertain tone: "For the sake of resources, it can also be said to be the future living space." ”

Seeing that Ding Xiu was a little puzzled, Chen Jianing added some of his own thoughts: "After experiencing the world war, human society has suffered great damage, and the newly established country will start a new round of competition. We Grellians love peace, but peace needs strength to keep it. The country that poses the greatest threat to us is the Elbrand Empire, and most of the friction on the border is created by them on their own initiative, and as you can see, their hands have even reached the town of Luxu. ”

"The Elbrand Empire is all bad guys."

"It's not all, there is no good or bad between countries, only interests." Seeing that Ding Xiu's understanding was a bit one-sided, Chen Jianing corrected: "And my grandfather once said that if you fall behind, you will be beaten." ”

"If you fall behind, you will be beaten!" After this sentence came out of Chen Jianing's mouth, it began to echo in Ding Xiu's heart.

Ding Xiu thought of Wu Mo and his seventh squad, and thought of more other things.

"Your grandfather must be an amazing man." He thought for a moment and said.

This evaluation did not have a trace of flattery, and it completely came from Ding Xiu's heart, because the truth that if he was backward, he would be beaten.

"You're right, grandpa is the person I admire in the world." Chen Jianing nodded, and Ding Xiu's evaluation of her grandfather made the girl very happy.

"When my grandfather saved my grandmother during the zombie virus outbreak, it was forty years ago." The topic turned to his grandfather, and Chen Jianing's interest was much higher than when he talked about the Elbrand Empire just now.

Listening to Chen Jianing talk about her grandfather's previous experience, Ding Xiu suddenly yearned.

"I'd love to see your grandfather when I have a chance."

"Really? There will be a chance. When she said this, the girl's eyes smiled like crescent moons.
