The sky was overcast.

The zombies in N City seem to have been affected by this bad weather, and there is no movement. The city of N is as dead and silent as a ghost town.

Lu Li and the others stood on the roof of a six-story building on the outskirts of the city, and they did not move. Ten minutes later, Lu Li lowered his head and glanced at Di Yu. The latter understood, and immediately teleported away from the roof with him. When they reappeared, the two had already arrived at a middle school on the outskirts of the city.

As soon as they appeared, the two of them immediately put on the helmets they had snatched from the men in black. After a slight adjustment, Di Yu raised his hand and pointed to the overgrown football field, and then walked ahead to lead the way.

A short time later, the two entered the football field. Di Yu searched for a long time, his eyes suddenly lit up, and then he walked forward quickly. He crouched down, put his hands into the thick grass, and struggled to lift a steel plate the size of a door panel.

When Lu Li saw it, he quickly stepped forward and assisted Di Yu in lifting the steel plate aside. Behind the steel plate was a staircase that went down into the darkness.

At this time, Di Yu turned on the small flashlight, beckoned, and walked down first. The two of them went down the stairs. Soon, they reached the end.

This is a man-made cave and square. The walls still bear traces of unfinishedness. Apparently this is a secret exit, but for unknown reasons, it is temporarily suspended.

Di Yu walked to the opposite wall with ease, picked up the flashlight and shone it, then grabbed a pull ring on the wall and pulled it hard. A crack appeared in the wall. He let go of the iron ring, and a teleportation carried Lu Li inside.

Behind the door is a world of silvery metal. The ceiling, walls, and floors are covered with silver metal, so clean that it can even refract the light of a flashlight. Only the floor near this door has a lot of dry hard dirt, and it is clear that it has been abandoned for some time.

Di Yu raised the flashlight to shine left and right, then beckoned to Lu Li, and then tiptoed towards the corridor on the right. Lu Li looked funny, and followed with a smile.

After a while, Di Yu sneaked up in front of a half-open and half-closed metal door like a thief breaking through an empty door. He looked left and right for a moment, then slipped in.

Lu Li was speechless and followed in silently. I don't want the room to suddenly light up. He was shocked, but he inadvertently saw Di Yu take off his helmet. His complexion changed, and he immediately opened his mouth to stop it. Before he could say anything, Di Yu had already given an explanation.

"Whew, I'm finally able to speak."

Di Yu hugged the helmet, looked at Lu Li with a smile and urged, "Brother Lu, hurry up and take this thing off." Here is the blind spot of surveillance. No one will find out that we've gotten in. ”

Lu Li was stunned, and then took off his helmet as well. He looked around and asked, "How often do you come here?" ”

Di Yu nodded proudly, his face full of pride: "Of course, a week ago, I found out that they installed that thing here, so I secretly observed it for a while. When they were all done, I took it back with me. But I didn't expect to come here next time, there was no one left. There were also a few times when they chased them closely, and as soon as they fled here, the pursuers were gone. So, now this is my base. Every time I come to get something, I have to hide from the limelight here. ”

Lu Li was quite speechless. Di Yu didn't know, but he knew it very well. The scale of the base in N city is not comparable to that of the No. 1 base. But it's not small. Without the assistance of artificial intelligence, it is not easy to manage such an underground base.

The subsystem was obviously deliberately installed in order to open up new areas and expand the scope of control. Now the subsystem has been taken away by Di Yu. It can only be abandoned temporarily.

But safety is security here, and there is nothing usable. For example, laser weapons, or networked systems.

He didn't believe that the AI had been formatted by the man in gray. Otherwise, not to mention now, Di Yu had already been arrested when he sneaked in for the first time, and he didn't have the slightest power to resist.

He knows the power of artificial intelligence. Especially the management base. Base 1 covers an area of more than 5,000 square kilometers. The base was functioning in an orderly manner without the slightest chaos. This is still the result of the artificial intelligence being left at the base in N City by Professor Hu. He believes that if all the underground bases are connected, AI can also be managed in an orderly manner.

Lu Li looked around, and then looked down at Di Yu: "Where did you get those laser weapons?" ”

Di Yu smiled, flipped his hand over like a trick, and then handed it to Lu Li. Lu Li took a look and saw a square, matchbox-sized silver metal block lying on his palm. He asked, taking the piece of metal and looking at it.

"What is this?"

"This is a small invention of Brother Han."

Di Yu took the metal block in Lu Li's hand and pressed it on the top. The top of the metal block lit up with a little green light. He handed the thing back to Lu Li and explained with a grin.

"We call this thing kill-to-death. This thing can emit electromagnetic waves of a specific frequency that interferes with the brain and makes people faint. It's like a stun gun. ”

Speaking of this, he muttered with some regret: "Easy to use is easy to use, but the scope is a little smaller." You can only press this thing on someone else's head to have enough effect. Now, except for me, they're all putting this thing on iron bars against cyborgs. Lo and behold, there's a transfer switch next to it, which can be adjusted to take effect on humans and on zombies. ”

Lu Li smacked his tongue secretly, turning over and over to look at this inconspicuous thing. Now he understood why the ordinary survivors of yesterday had been able to hold out for so long.

Di Yu looked at Lu Li and looked at it over and over again, and muttered boredly: "It's not good to use this thing to deal with biochemical beasts." You can't stun them, you can only dull them. ”

As soon as the words fell, Lu Li suddenly raised his head and smiled mysteriously at Di Yu: "Do you want to come and play big?" ”

Di Yu's eyes lit up, and he nodded again and again, looking eager to try. In the past, I sneaked into here, only daring to pick up leaks and stun a few lonely people in black. Since Brother Lu is also here, how can he be worthy of himself if he doesn't play a big game.

Lu Li laughed, pulled Di Yu over, and whispered a few words in his ear. Di Yu listened, his face was full of surprise, and he couldn't stop nodding.

……

In the hallway, a two-person patrol team conducts daily patrols with laser weapons. Suddenly, a smug laugh echoed through the quiet hallway.

"Sinners......

As soon as the laughter started, the two men in black immediately followed the direction from which the sound came from and raised their guns and pulled the trigger. Suddenly, two blue beams of light shot out and hit the wall straight away. The silver metal that makes up the entire base is an unknown alloy. These two laser beams hit it, leaving not even a single trace, as if they were completely absorbed by the wall.

"Assert ......"

A series of strange laughter quickly faded away from near and far. Without thinking, the two men in black immediately chased after them. They chased the laughter and scurried all the way. As they turned a corner after the laughter, two thumb-sized steel balls suddenly shot head-on. The two were caught off guard and were hit in the forehead by a steel ball.

When they landed, the two black-clothed men seemed to have been kicked in the head fiercely, and fell to the ground on their backs. Almost at the same time, there were two terrible muffled bangs, and both of them lost consciousness at the same time.

At this time, Di Yu appeared beside the two of them and happily took off the laser weapons in their hands. He carried the two laser weapons onto his body and grinned at Lu Li, who was walking towards him.

"I'll go put it away first, and I'll be right away."

Lu Li smiled and said nothing, acquiescing to Di Yu's plan. When Di Yu teleported away, he walked over to the two men and crouched down, pulling out his dagger and slitting their necks. I don't want to cut the neck of the last person, and the red light in the corridor flashes rapidly. A shrill siren echoed.

"Found out so soon?"

Lu Li was a little surprised. He stood up and casually tucked the dagger back into his waist. After doing this qiē, Di Yu just returned here. As soon as he appeared, he immediately urged excitedly.

"Brother Lu, it's time to do it."

Lu Li nodded happily, and his mental power immediately quietly probed out, enveloping a radius of five hundred meters. After a while, he glanced at Di Yu and walked forward quickly.

Soon there was a dense rush of footsteps in the hallway. Groups of men in black hurried down the hallway towards the area where the alarm had been raised.

The first team was the first to reach the area. There are ten people in this squad. Under the command of the men in black at the head, they slowed down and moved forward with good training. As soon as he walked around a corner, more than 20 steel balls suddenly **** out of the corner at a speed invisible to the naked eye.

The steel balls made a strange turn in the air, enveloping the team. They reacted immediately and immediately opened fire. Dao beams are connected into a dense net. And those steel balls shuttled rapidly, dangerously through the narrow gaps, and smashed straight down.

In the face of this bizarre attack, they did not hold out for long. About half a minute later, ten unconscious men in black fell to the ground and did not move.

At this time, Di Yu showed his figure, quickly picked down the ten laser weapons, and teleported and disappeared again. After a while, Lu Li walked briskly, holding the more than twenty steel balls suspended around him.

"It's a bit far away, maybe it's better to control zhì within twenty meters."

Lu Li whispered to himself as he squatted down to harvest the lives of these black-clothed people. Dealing with ten unconscious people did not delay him much. When the neck of the last person was cut, Di Yu had already returned.

Soon, in the rush of alarms, the team of men in black was attacked. Lu Li and the others walked down the corridor like ghosts. Everywhere you go, there is a bloody storm. No one escaped the duo's murderous hands.

The sirens became more and more urgent, and more and more teams of men in black rushed to the area. Their actions were all under Lu Li's telekinetic surveillance.

He also took it when he saw it, and when he cut the neck of the last man in black, he beckoned to Di Yu, who was rushing back here: "It's time to go back, come back next time." ”

Di Yu scratched his head reluctantly, and then returned to the room with Lu Li as he said. Unbeknownst to them, what they did was faithfully recorded by the surveillance cameras in the hallway.
