Seeing Zhang Yang leaving without hesitation, everyone in the car didn't know what to do for a moment. Chu Jianqing's eyes were filled with tears, while Chen Lang punched the dashboard of the off-road vehicle, cursed "bastard", and then stepped on the accelerator.

"Zhang Yang is crazy, are you crazy too? How can we leave him behind!" Chu Jianqing's voice was crying.

"He is not crazy. A madman can't do such a thing. Zhang Yang is the most rational now." Chen Lang's eyes appeared in front of him. Every time a companion died in front of him, he would have this hallucination that made him extremely painful. It seemed that behind the off-road vehicle, a group of souls floating in the air followed him. Through the rearview mirror, Zhang Yang could still be vaguely seen, but Chen Lang did not dare to look at him, and even dared not turn his eyes to the rearview mirror.

He was afraid to see Zhang Yang lying in a pool of blood.

The fat man sat in the passenger seat with a calm expression, as if he didn't care about Zhang Yang's life and death at all.

"Hey, Fang Heng, the situation here has changed." The fat man contacted Fang Heng.

A glimmer of hope appeared in Chu Jianqing's eyes.

Yes, the only one who can save Zhang Yang now is probably Fang Heng.

Because Zhang Yang attracted all the attention of the zombies, the Hummer did not encounter much obstacles on the road. After breaking out of the encirclement, it left.

far away.

The shadow of the tall marble arch becomes more and more blurred in the night, and finally merges with the night.

Only a roar came from the direction of the arch.

At this time, the fat man ended the communication with Fang Heng.

"What did Fang Heng say?" Chu Jianqing asked hurriedly.

The fat man shook his head.

Although there was not even a single word, the result was self-evident.

Chu Jianqing leaned on the seat and felt her shoulders sinking suddenly, and the air made her breathing uncomfortable.

Chen Lang was also in a state of desolation.

I'm afraid that the talkative guy will never see him again.

The fat man said, "I can only pray that he will be blessed and happy."

In the subway tunnel in New York City.

At night, the zombies here are more frequent than during the day. They do not need clocks, but they can also grasp the time when the sun rises and sets all year round, so they can retreat to the ground before sunrise without being exposed to the sun. Zombies are used to hiding out at night, so when the time comes, their biological clocks are automatically dialed to eat and move.

Cao Nian and the other three stood beside a collapsed wall. In addition to mud and bricks, there was also some water accumulation on the ground.

In addition to the rainwater seeping from the upper soil, the accumulated water on the ground also had liquid produced by the corpse's decay and some zombie excrement. Although there was air flowing in the tunnel, the quality of the air was still very worrying. Although he had already put on a mask, Cao Nian still felt that the smell was still irritating his nerves.

Xu Nuo stood on the rails, crossing his feet forward and backward like he was walking on a cat step. She was not pretentious, but the things on the ground were too disgusting. As an exquisite little woman, she would rather choose to walk on the narrow rails than walk through the mud like Cao Nian and Fang Heng.

Cao Nian actually didn't know what the mud was on his feet, so he didn't feel so disgusting. If his eyes were still healthy, he would probably not be so relaxed.

Standing next to the track repair car, Fang Heng said to Cao Nian: "Move this car to the rails outside."

The wall was exactly the piece that Zorro had chiseled through earlier, and this simple repair car was also discovered by Zorro before. Although the wheels were still moving, the power system had been damaged due to long-term corrosion by oxygen and water. Cao Nian stood next to the vehicle and reached out to touch it. The touch felt slightly cool and very rough. He could feel how serious the rust on the surface of the vehicle was.

Cao Nian suddenly thought of something, and he whispered: "Today you ask me the limit of my mental power. In fact, it is to test whether I can move this car, right?"

Fang Heng did not deny this, but said mysteriously: "Yes, but not all."

This answer is plausible, but Cao Nian did not delve into it, but just smiled helplessly. Cao Nian could only accept the fact that he had changed from a combatant to a porter. Although he did not think that this car could be of great use - unless Fang Heng could repair the car. However, all the lines and devices except four wheels were broken. It was no easier to repair it than to rebuild a new car. Fang Heng obviously did not have this ability, and time would not allow it. It was obviously not a wise decision to spend time and energy on this car, and Cao Nian still couldn't keep up with Fang Heng's brain circuit.

"Huh?" Just as Cao Nian was about to take action, Fang Heng suddenly said in confusion: "Is it Fatty and the others?"

"Fatty? There?" Cao Nian was stunned, and then he realized, "Oh, are you saying they are contacting you? Contact us at this time, probably because he is worried about our safety."

Because of the danger of their trip, Cao Nian took it for granted that the fat man contacted them out of concern, just like a greeting to his friend before leaving. Cao Nian was slightly moved. Fang Heng did not respond to Cao Nian's naive thoughts. He just listened quietly to the fat man's voice coming from the other end. Seeing that he ignored him, Cao Nian took this time and moved the construction car on the old railway track to the new railway track according to Fang Heng's order. Although the two railway tracks were built differently, the specifications were the same, so the track maintenance car could perfectly fit the new railway track.

It took Cao Nian less than three minutes to finish all this.

Fang Heng also ended the call and said to the fat man on the other end: "Since that's the case, you can do whatever you should do, and you will give all the command to you, so don't ask me again; of course, if there are still variables... Just do it like this, you can do the rest yourself."

After hearing Fang Heng's words, Cao Nian felt something was strange because he heard a little panic from Fang Heng's words, which was not common in Fang Heng.

Xu Nuo has been standing next to Fang Heng, so he is most clear about his emotional changes. She also clearly felt Fang Heng's anxiety. She asked, "Is there something wrong there?"

Fang Heng shook his head and said, "It's okay, don't worry. Let's continue."

Cao Nian and Xu Nuo both knew that things would definitely not be as simple as Fang Heng said. However, Fang Heng didn't want to say it. Even if they asked, they would just add to their worries. So the two of them made up their minds in a tacit understanding and ignored the matter.

The underground tunnel is connected to all directions and there are many exits. Fang Heng released two reconnaissance aircraft to monitor the surrounding situation. They are lucky. There are no zombies here for the time being, so they don’t have to hide and don’t have to worry about being discovered for the time being.

"First of all, we have to pull out those ordinary zombies." Fang Heng said, while taking out a small suitcase from the space pocket and taking out a tube of reagent from the box. "Some animals communicate with each other by secreting pheromones, so I guess that the reason why blood can attract zombies is because they are extremely sensitive to the chemicals in it. The reason why Zhang Yang's blood is more attractive to zombies is not because the zombies know that their genes are strong, but because the content of this chemical in his blood is higher than that of ordinary people! After research, I found this chemical that attracts zombies, which I call hemopheromones. The structure of this substance is actually very simple, with only twenty-two hydroxyl groups, and... "

Cao Nian quickly made a statement to stop Fang Heng's popular science, "We are not interested in biology, I just want to know what you plan to do next."

Fang Heng hesitated for a moment and said, "Actually, what I just mentioned is mainly chemistry."

"I know I'm an idiot, okay, you'd better tell me your solution."

"good--"

In the lower civilization, the stricter the division of social hierarchies is often, which is particularly obvious in the zombie world. Lord-level zombies are as majestic as rulers in their group and have the power to kill and seize life and death. Those weak zombies are completely slaves, not only at the risk of being killed at all times, but also need to "provid and hand over food" to the lords. The food they get is often only a small part of, while most of them need to be handed over to the lords.

Under such exploitation, ordinary zombies are usually orders of magnitude worse than the lords. In the long run, the lords will become stronger and stronger, while the 'slaves' will become thinner. Therefore, most people live no differently after becoming zombies than before. They are still exploited and exploited, but they are just more naked.

The intermediate lord leaned on the throne made of metal, motionless, as if he was in a half-dream and half-awake state. It is now in the evolutionary stage, like a silkworm, requiring a quiet environment to slowly complete the transformation of his body. Several primary lords guard it next to it, looking loyal.

As for those ordinary zombies, they stood in piles on the rails, like a nest of piglets in captivity.

Some zombies have gone out to find food. Only 70% of the zombies left here are as high as during the day, but the number is still amazing.

The air underground is very dirty. Not only is the oxygen content low, but the air is filled with the smell of rotten and moldy substances. However, zombies have adapted to this environment, so they do not feel uncomfortable. However, due to the large demand for oxygen, they have to increase their breathing frequency. After living in this environment for a long time, these guys are not used to the air on the ground. Too fresh air often makes them dizzy. This situation also occurs frequently in humans, and has a very interesting name called "intoxicated oxygen".

Zombies are grabbing oxygen from the air.

But they suddenly smelled a scent that made them feel extremely excited in the slow-moving air.

All the zombies looked up at the darkness.

There is food there!

Although the environment here cannot attract any animals, especially those large mammals, occasionally animals get lost and come here by chance.

Today seems to be a lucky day!

The smell was so attractive, especially for ordinary zombies that were already hungry, so before the lords issued orders, some zombies left the team and rushed towards the prey. With the first one, there would be a second one. Gradually, hundreds of zombies searched for the darkness.

The originally dead subway tunnel became noisy in an instant, and the roars of zombies came one after another, just like the howling of wild wolves in the dark.

A figure is running in the tunnel.

His speed was very fast, and the harsh environment in the tunnel could not have much impact on him. Behind him were hundreds of zombies. These guys jumped in the tunnel like jumping spiders, and each time they could jump out four or five meters. Driven by the bloodthirsty **, they showed amazing physical strength. These zombies became more and more excited, and their screams even formed air waves in the tunnel.

The figure who was "leading the way" ran all the way and finally escaped from a subway exit. Hundreds of zombies followed him and came to the ground.

In the tunnel.

Cao Nian and his group hid in a small room where subway inspectors were resting. They waited until the sounds outside disappeared before they came out.

They turn on the searchlights.

The ground was full of footprints left by zombies.

It seems that an army has just passed here.

Cao Nian said with lingering fear: "The zombies have left, now we can start the second step."

Fang Heng nodded and said, "In fact, I have started the bomb."

As soon as he finished speaking, he heard a violent explosion from the subway exit in the distance! And the sound continued, just like a series of firecrackers. In less than a minute, more than 20 nearby subway exits were all blown up!

Hundreds of zombies on the ground want to go back to the ground, so they can only go to the subway entrance farther and walk back slowly from the tunnel. If they are smart enough, it may only take a few hours to slowly fumble back, but these guys are still too stupid after all, so it takes far more than a few hours.

The subway exit collapsed and the load-bearing wall collapsed, and the entire platform area was affected. In some places, stones and soil even blocked the entire tunnel. A large amount of dust suddenly rushed into the tunnel.

Cao Nian and others were wearing masks. Although they could not smell the dust, they could vaguely feel some tiny particles coming with the wind and hitting their masks, making a sound like drizzle falling on the glass.

But the situation is not that comfortable now.

"How should we leave the underground tunnel after we kill that monster?" Cao Nian suddenly thought of an important question.

Fang Heng turned his head to look at him and said in confusion: "Leave?"

Cao Nian suddenly had an ominous premonition: "You might not have planned to leave, right?"

Fang Heng said: "Of course not."

Cao Nian said: "Can't we leave from other subway exits? Although the distance may be much further?"

According to Fang Heng's previous statement, the subway exits several kilometers around have been blocked. If you want to leave, you need to go to the exit further.

Fang Heng shook his head: "That was my lie to you - in fact, in addition to blowing up the subway exit, I also blew up all the tunnels connecting this area."

"In other words, we have no other way except moving forward?" Cao Nian realized that he had thought things too simply. Cao Nian thought he was just blowing up the nearby exit, but he didn't expect that he even blew up the tunnel.

It turned out that Fang Heng had no way out at all.

In other words, they are now trapped underground!

Even if the zombies outside find the intact subway entrance, they will never find the way back to their nests. No zombies can come in, and no zombies can go out.

Of course, Cao Nian and his group of three were not good either. Because there was no road here.

And the initiator of all this was Fang Heng.
