Ye Hao cracked the T4's ability camouflage technique in that weird room. After a lot of fighting, at the moment when T4's killing machine was about to break, he used the hole card skill that had been hidden all along, absolutely static, in an attempt to regain the advantage.

Ye Hao used the skill "Absolute Static" to buy a little time, and raised the sapper shovel with both hands and slashed at T4's neck.

"Click!"

Unexpectedly, the sapper shovel actually cut in less than an inch before it became entangled in T4's hair.

Ye Hao's face changed, he definitely didn't expect that the other party's cuticle was so hard, and the glimmer of life that he had tried his best to win by using his skills seemed to be shattered, and the balance of victory was once again tilted towards T4's side.

"Roar!"

T4 quickly resumed his actions, and although he didn't know the reason for his imprisonment, he instinctively knew that he had to deal with the human in front of him as soon as possible. I saw half of its face smiling, and its left claw was raised high, slashing down at Ye Hao's head.

At the moment of crisis, Ye Hao smiled slightly. Launching the skill "Absolutely Forbidden" again, a cold light flashed in his eyes, and he let go of the sapper shovel in his hand, and at the same time, his right hand flipped over, and the electromagnetic rifle in the space appeared in his hand.

He plunged the electromagnetic rifle into T4's roaring throat and pulled the trigger.

"Wow!"

A scorching electric glow passed through his body, and a foul smell came, and a hole appeared from T4's bloody mouth to the back of his skull, and a look of surprise and unwillingness appeared on T4's hideous face. The head was pierced, and T4's claws hung limply.

"Bang!"

Kicking T4's body away, Ye Hao stood up, picked up the sapper shovel that fell to the ground, and cut off T4's head. The crystals in T4's brain are precious items, and when he broke through at the Maple Leaf Base, the T4 crystal that he killed was wasted, which made Ye Hao feel distressed for a long time.

Ye Hao endured the nausea and dug out the green fourth-level crystal, integrated it into the dragon-shaped tattoo on his left forearm, and after kicking the disgusting head, he took out fresh water from the space and cleaned the disgusting liquid on his hands.

At this time, the suppression of T4 was lost, and the large group of zombies gathered outside the door poured into the room, but this room was very large, and there were many server cabinets inside, unlike corridors and other places that were narrow and lacked barriers. Ye Hao took advantage of the terrain and the abundant firearms and ammunition in the system space to quickly slaughter these lowest-level T1 zombies.

The continuous fierce battles exhausted his physical strength, but in this room that had a fight with hell, Ye Hao really couldn't eat, he just drank some water, and after resting, he blew the iron door open.

The space behind the iron door is very large, and it is divided into several areas, each of which is not small, and the largest area is at least 1,000 square meters, which is stored with computer components.

After Ye Hao searched carefully, he finally found dozens of survivors in a place similar to a storage room, all of whom were lying on the ground, dying. Ye Hao thought that these people were corpses at first, because they didn't react to the big movement of the iron gate being blown up, and they also turned a blind eye when they walked in. As a result, he walked over to check it and found that these people were only malnourished for a long time, and it was estimated that they had not eaten for several days.

Ye Hao had to take out the rice and boil porridge on the spot. As a result, without waiting for the porridge to boil, the fragrance of rice porridge attracted these people who were waiting for death one by one. A large pot of porridge was eaten in the blink of an eye, and he had to cook two more pots, but they still swept them away. Under Ye Hao's strong distribution, each of these people was given a small bowl of rice porridge, and Ye Hao didn't cook it again, because they were hungry for too long, and eating too much could easily cause gastrointestinal discomfort, and even life-threatening.

After adding a little food, these people are not in danger of life for the time being, but due to long-term hunger, they are weak and have no strength to leave here, Ye Hao thought about it, returned to the ground and took the members of the team underground, planning to repair it on the second floor of the basement, and wait for the physical strength of these survivors to recover before leaving.

In order not to arouse suspicion, he later found food in another room under the pretext of finding it, and then took out part of the food stored in the space, and if he had food, he stayed on the second basement floor to repair.

Three days later, the survivor, who was originally dying, quickly recovered his health with the supplement of food, and although his body was still a little weak, he was able to walk and run on his own.

During this period, Ye Hao also met Dr. Silan, and through the conversation with Dr. Silan, he finally knew the reason why Dr. Silan and the others were trapped here.

It turned out that after the cataclysm, survivors of Silicon Valley also built a gathering place nearby, with a population of about 30,000. But three months ago, the gathering place was attacked by zombies, and there were about 200,000 masters besieging the gathering place, and the zombies were not necessarily able to break through the defenses by relying on the force of the gathering place, but in this group of zombies, in addition to T2 and T3, there were two T4s. One of them is the female T4 who was killed by Ye Hao, which has the ability to hide traces, and the other has the ability to stimulate the potential of ordinary zombies, which greatly stimulates the ability of ordinary zombies through sound waves.

The two T4s cooperated, the Hidden T4 used his special ability to sweep away the upper echelons of the gathering place, and the Intensifier T4 doubled the ability of the besieging zombies. As a result, the defense of the gathering place was broken in the first round of zombie attacks, and then the survivors of the gathering place were greeted by a horrific massacre.

There may be some survivors who break through, but the number of survivors in the entire colony will not exceed 10% of the original population.

Dr. Slan and a few others retreated to the building during the upheaval, but unfortunately they were targeted by the Hidden T4, and less than 100 people survived. They locked the iron door and got rid of T4's pursuit.

The area where Dr. Slan and the others are located was his laboratory before the cataclysm, because it was built relatively strongly, and after the establishment of the gathering place, it became a storage warehouse for materials and materials in the gathering place. There was some grain stored in it, which was why Dr. Slan and the others retreated here. However, after more than two months, the food in this place slowly dried up, and some people tried to rush out to find life, but in the end, they were all killed by the T4 waiting outside the door, and the rest of the people finally locked the iron gate completely, giving up hope of leaving, and slowly waiting for death as the food ran out.

No wonder Ye Hao found that the corpses were decomposed to different degrees in the room outside, and he thought that it should be survivors who tried to leave at different times.

With Dr. Silan's consent, Ye Hao finally saw the legendary artificial intelligence. In his imagination, artificial intelligence should be similar to the robot in the movie "Mechanical Public Enemy".

To his surprise, Dr. Slan showed him a room of nearly 100 square meters. There were all kinds of machines in the room, and Ye Hao didn't know any of them anyway.

According to Dr. Slan, all the machines in this room are the ontology of artificial intelligence!

These machines, including processors, memory, 3D projectors, and more, were all state-of-the-art technology before the cataclysm, and Dr. Slan and his team officially used these materials to complete the creation of artificial intelligence.

However, after the cataclysm, the ontology of the AI was not harmed due to the fact that it was deep underground, and the laboratory was built with materials to isolate electromagnetic signals. But the small fusion reactor that provides the AI operation has been devastated, so the AI that lacks energy cannot operate and has been kept in this laboratory.

"Robert, can you find a way to get Andy out of the country?" Dr. Slan asked after recounting the whole story.

"Dr. Slan, I'm afraid I'm going to disappoint you. Although Ye Hao had a way to transfer Andy, he didn't tell the truth to Dr. Silan, it was a matter of the system's tasks, and he didn't know how to explain it to Dr. Silan.

"It's that I'm too extravagant, and Andy is of no use to the world right now. Dr. Slan caressed the machine beside him.

"Doctor......" Ye Hao didn't know how to comfort Dr. Silan.

Dr. Slan waved his hand: "I'm just unwilling, Andy has cross-era significance for mankind, but it's a pity that he was born at the wrong time!"

"Doctor, Andy will be useful. ”

"Thank you, Robert. Dr. Slan smiled wryly.

After discussing with Dr. Silan, Ye Hao decided to blow up the exit of this room before leaving, so as to prevent Andy's body from being destroyed.

It's time to leave.

Everyone was ready to go, and Ye Hao accompanied Dr. Silan to the room where Andy's body was placed again.

Ye Hao planted explosives at the door, and Dr. Slan entered the room to say goodbye to Andy.

After installing the explosives, Ye Hao entered the room and said to Dr. Silan: "Doctor, let's go! When the conditions allow, we will come back and transport Andy away." ”

After a moment of silence, Dr. Slan nodded and walked out of the room.

"Doctor, you go first, I'll wait until you leave before blowing up the exit. ”

Dr. Silan thought that Ye Hao was worried that he would be sad to witness the explosion of the exit, so he left silently.

After Dr. Silan walked away, Ye Hao walked into the room, touched his hand on the machine, and silently said in his heart, "System, start working." ”

After a while, Andy's body in the room disappeared in front of Ye Hao's eyes.

"Artificial intelligence has been included in the system space, and this system places artificial intelligence in a specially opened space, which does not consume the volume of the space owned by the host!"

After all Andy's main body was included in the space, the exit of the room was blown up with a loud bang.

Ye Hao rushed to the meeting point, and everyone was waiting here to prepare to leave.

"Let's go!" Ye Hao ordered.

Ten minutes later, Ye Hao and the others walked out of this building that was like hell, and everyone felt as if they were in a different world, especially the survivors such as Dr. Silan, who thought that they had returned to the world from hell.

Ye Hao bumped his head with Barnes, who had left the investigation first. According to Barnes, their arrival didn't cause much movement, so the area didn't change much. In addition, Lawrence is a block away, observing the movement of zombies.

Ye Hao nodded in understanding, and then the group began to evacuate in an orderly manner.

By the time they got back to where the vehicles were parked and arranged for the rescued survivors to get on the buses they had brought, Lawrence had not yet returned.

Afraid of an accident, Ye Hao took a few people back to find Lawrence. This incident also reminded him that there are many inconveniences in whether to buy a batch of walkie-talkie equipment from modern society and put it in the team, and the lack of means of communication.

They returned to the intersection they had entered, and at the end of the street there was Lawrence, behind him a dense crowd of zombies. For Lawrence's physical strength, running a few hundred meters is not a problem, but Lawrence feels like he has run away, completely running at full strength.

Discovering this abnormal situation, Ye Hao's expression that had been relieved because of Lawrence coming back became serious: "Prepare to fight!"

Ye Hao took out a telescope and looked at Lawrence, only to see that there were more than 100 zombies behind him, and they were frantically chasing Lawrence. After searching through the group of zombies, he didn't find any suspicious targets, his gaze extended backwards, and the sides of the street and the buildings were also not found.

When Lawrence was 100 meters away from them, he was heard shouting loudly: "Robert, you guys retreat quickly, there are high-level zombies, retreat quickly!"

As Lawrence shouted, a sharp sound sounded like metal scratching over glass, causing eardrums to ache and produce a sense of irritability.

The zombie group behind Lawrence was in the shrill sound of this life, and the speed of running was slightly slower than that of normal humans, but suddenly it seemed that he had been stimulated by some kind of stimulation, and he actually chased after Lawrence at a speed far beyond the full strength of normal humans.

"What's going on?" Ye Hao looked at the situation in front of him dumbfounded, how did these zombies do this?

Ye Hao looked at Lawrence, who was running for his life, and a look of fear appeared on his face. He couldn't believe that an elite soldier who had been trained, who had always been optimistic and cheerful, and who had been fighting zombies for a year in the last days, would be afraid of zombies.

"Damn, it's the Inspirator, the T4 that broke through the Silicon Valley Cluster!" Ye Hao finally sounded Dr. Silan's description, and the Silicon Valley Gathering Area fell with the cooperation of it and the Hidden One.

Among the zombies that have reached level T4, the individual attack power of the intensifier is not strong, and it is a high-level zombie belonging to the support type. However, this auxiliary ability of his is fatal to humans, he can radicalize the loss of crystals in the brain, so that the zombies can gain a short-term potential explosion. This intensification increases the loss of various abilities such as speed, strength, reflexes, and so on.

The only reassuring thing is that the number of intensifiers is limited, taking T4 as an example, it can only radicalize zombies below 1000 at a time, and it is only effective against T1, otherwise the exacerbators will be a complete disaster for humanity.
