Not long after the off-road vehicle drove up the ring road, it stopped in front of a 4S store on the side of the road. Lu Li and the three of them cautiously opened the car door and got out of the car quietly.

This is already the territory of the cyborgs. To this day, even Lu Li is unwilling to provoke an entire city's biochemical beasts. As the saying goes, two fists are hard to beat four hands. A mere beginner evolutionary plus two second-stage enhancers are no match for hundreds of thousands, or even hundreds of thousands, of biochemical beasts. Once encircled, I'm afraid that only Di Yu's teleportation can take everyone out of the encirclement safely.

But the key thing is that Di Yu is not there at the moment.

There was no communication, no advice, and the three of them tacitly walked all the way along the ring road. Except that Yang Yuting came to N City for the first time, Lu Li and the others clearly remembered that there was a hidden base entrance a few hundred meters away.

The city was dark and lifeless, but the weather was not good tonight, not only the moon, but not even the stars. The whole city was shrouded in deep darkness. Ring Road is no exception.

Fortunately, such an environment did not have much impact on Lu Li. Although the night covered the earth, he still walked on the ground, leading the two of them all the way.

Lu Li's body has been strengthened twice, and Su zhì is not bad. And Liu Qiang and the others are pure strength-type enhancers, and Su zhì is far away from him. A few hundred meters away, it takes less than ten minutes.

This is the office building of the Local Taxation Bureau. The three of them walked past the guard room and went straight to the back of the building. At this time, Lu Li raised his hand and patted the two on the shoulder, signaling the two to wait here, and then walked quickly to the foot of the building. With his back against the wall, he walked forward in a very regular manner.

Walking out of Moyo three meters, he stopped. He stepped on it a few times, then crouched down and began to grope on the ground. Soon, he touched a stone that was barely a centimeter above the ground. Finding the mechanism that opened the secret door, he pressed the stone without thinking.

Just press down on the stone. The ground shook slightly, with a low rumbling sound. Lu Li heard the movement under his feet, and immediately got up and retreated two or three meters back.

He had just stood firm when the position he had been standing in suddenly sank, revealing a hole about two meters long and wide. After a few moments, the rumbling sound died down. He immediately walked quickly back to Liu Qiang and the others.

"Let's go."

Lu Li let out a low snort, scribbled his hands left and right, grabbed the hands of the two and walked quickly to the hole. Soon, the three of them walked up the steep staircase in the entrance of the cave.

After a while, the three of them arrived at a platform. Lu Li let go of the two, swept left and right, and then raised his foot to step on a bulge about half a meter away. After a while, the rumble sounded again. A platform extended from the wall above the trio's heads, and they rose straight up.

Only then did Lu Li breathe a sigh of relief and took out a flashlight from his pocket. The flashlight turned on, and the light dispelled the darkness. Liu Qiang and the others regained their light from the darkness at first glance, and subconsciously raised their hands to cover their eyes. After a while, the two of them got used to it and put their hands down.

"It's safe now."

Lu Li smiled and raised his eyes to look at the bottom of a staircase that stretched to an extremely deep depth: "At least don't worry about those things chasing after you when they hear the sound." ”

Yang Yuting also took out a flashlight at this time. She looked around curiously by the light of the flashlight, and finally looked at the staircase with Lu Li's gaze: "Brother, is the entrance to that base below?" ”

"Well, this is one of the many entrances and exits to the base."

Lu Li looked at the long staircase with no end in sight, pondered for a moment, and then briefly ordered: "Let's go, go and see what is going on at the base." ”

The three of them walked up the stairs again. It took nearly half an hour to walk. Half an hour later, the trio came to a spacious artificial cave. This is already the end of the ladder. The surrounding walls were bare, with no sign of a door. This made Yang Yuting puzzled. She looked around suspiciously and asked casually.

"Is this really the entrance to the base?"

Lu Li smiled without saying a word, walked straight to the opposite wall, raised his hand and pressed somewhere. After a while, a crack suddenly opened in the wall, revealing a silver metal door.

Yang Yuting's eyes widened, and she walked quickly to Lu Li's side, looking up and down at this never-before-seen metal gate. Unexpectedly, after waiting for a long time, she didn't see Lu Li's next move. She looked over her head in confusion, but saw Lu Li's face solemn, staring directly at the metal gate.

"No response?"

Liu Qiang stepped forward and hesitantly raised his hand to grope around. Lu Li saw it and explained in a deep voice: "It's useless, every exit of the base will not be locked." Just open the cover on the outside and the door will open automatically. But now...... Something must have happened inside. ”

"I'll try to smash it open."

When the words fell, Yang Yuting had already rolled up her sleeves. She clenched her fists and punched out with all her unbelieving strength. All I heard was an unbearable muffled sound. The whole cave shook slightly, and a lot of fine earth fell from the top. The metal door didn't move, as if it were in two different dimensions from the cave.

"It's so sturdy."

Yang Yuting exclaimed in surprise and withdrew her hand incredibly. While rubbing her slightly red and swollen right hand, she looked up at Lu Li in frustration: "This door is so strong. How do we get in? ”

Lu Li couldn't answer this question. He frowned, and groaned as he stared at the metal door. He had seen information about the metal from the database that Eve had opened.

This is a special alloy that is a hundred times harder than steel and even extremely tough. In addition to this, this special alloy is not only able to withstand extreme impact forces, but also has a memory. Not to mention such things as extreme cold and high temperature resistance. It's a perfect alloy beyond human imagination. And this alloy is one of the mainstream materials used by the Interstellar Federation to make starship shells.

If you can control the zhì base, then the base built of this special alloy can be called one of the safest places in the world. Even if cyborgs evolved to know how to use nuclear weapons, it would not be possible to blast open such a door.

And now this metal has become the biggest problem.

Assault is no longer working. Yang Yuting has already tried it herself. Her evolutionary range is a little higher than that of Liu Qiang. She couldn't shake the metal door. Liu Qiang didn't even think about trying it at all.

Now there is only one way for the three of them - try to contact the people in the base.

And this only option has been given up by Lu Li. As early as City A, he used Eve's communication device tailored for him with extraterrestrial technology to contact Eve. He didn't think about the possibility of being able to contact Eve when he got here.

After thinking about it, Lu Li couldn't come up with a way to break the door if he wanted to break his head. After several hesitations, he gritted his teeth and took out the hologram from the inner pocket of his jacket.

The light curtain flashed, and Li appeared in front of the three of them. As soon as he condensed his body, his brows were already deeply furrowed: "I have reminded you many times. Although I absorbed a lot of Origin Mental Power last time, this holographic photograph was extremely expensive. Don't use ...... if it's not necessary"

As soon as he said this, he suddenly noticed that something was not quite right around him. He looked around hesitantly, and suddenly looked at Lu Li in surprise: "What's going on?" I feel like this base has been tampered with? Who is it? ”

A few questions were thrown in a row, and Lu Li was speechless. He cleaned up his feelings a little and explained briefly to the point: "Something happened here. My people can't get out of it and can't be contacted. So I want to ask you for help. ”

"Huh?"

Li thoughtfully looked up at the metal door in front of him: "This seems to be a phenomenon that only occurs when the base has turned on the defense mode and carried out a comprehensive blockade." At the beginning, I deliberately added an extra command to the program to turn on the defense mode. Only the highest privileges can be unlocked. Did you change the program without permission? ”

Facing Lihu's suspicious gaze, Lu Li was speechless. He is the only one who knows the base's highest authority orders. And he knew he hadn't done anything, and he hadn't even mentioned the supreme directives to anyone. In short, it is absolutely impossible for you or someone else to modify the program with the highest authority.

At this time, Li saw the expression on Lu Li's face, and knew that the abnormal situation of the base could not be caused by this human who he valued. He thought for a moment, then commanded.

"To disarm the defense mode, it must be dismantled by the guò supreme authority directive. If you find a port, call me out. ”

As the words fell, his whole body turned into a little white light, and he suddenly disappeared into mid-air. It was only at this time that Liu Qiang and Yang Yuting were greatly relieved.

"Brother, who was that person just now?"

Yang Yuting stuck out her tongue with palpitations: "I'm standing in front of him, I'm almost out of breath." ”

"Uh......"

Lu Li hesitated. However, seeing Yang Yuting and the two of them having palpitations, they casually perfunctory: "He is not an ordinary person." Luckily, though, he was able to help us solve the problems at the base. ”

At this point, he immediately changed the subject: "Look around and see if there are any external ports." We can't find it here, so we'll have to go to the other entrances. ”

As he spoke, he walked quickly to the wall on the right and searched for it. Yang Yuting and the two looked at each other, not satisfied with Lu Li's explanation at all.

However, Lu Li refused to tell the truth, and the two had no choice, so they had to look for an external port separately according to their words. Although this artificial underground cavern was spacious, it did not cause much work for the trio.

About half an hour later, the three met in front of the metal door. As soon as the information was gathered, the three of them couldn't help but be a little discouraged. Lu Li pondered for a moment, then walked to the wall and sat down.

"Let's rest here for the night, and then we'll leave tomorrow morning to take a look at the other entrances."

……

At the same time, the main control room was brightly lit. None of Qin Hu went to rest. The atmosphere in the base could not be hidden from them. The four of them gathered in the main control room to discuss what to do in case of a riot. After some argument, Qin Hu closed his eyes, took a deep breath, and said categorically.

"If there is really no other way, it can only be suppressed by force."
