Xiao Yuan did not leave the secret room, but released the nanobot, not only monitoring the secret passage outside the door, but also monitoring his father's office.

When Dangdang, Xiao Yuan had just arranged the nanobot when there was a knock on the door of his father's office, and then he saw his father stand up, walked over and opened the door, and the old man led someone to break in.

"Grab it." The old man waved his hand and commanded loudly.

Xiao Yuan saw that the old man asked his father to be arrested, then took a card to open the secret door, walked towards the secret room where he was, and soon came to the door, and scratched it with the card outside the door, and the door opened, and at this time, Xiao Yuan brought the helmet to his head again, but he did not connect the central system.

The old man asked people to guard the door, and only brought two soldiers to walk in, and after entering the room, he saw Xiao Yuan wearing a helmet and reclining on the black leather seat, so he walked over, took out another black card from his body, and inserted it into a socket on the helmet.

After inserting the card in, the old man seemed to be relieved, sat on another chair in the room, and guarded Xiao Yuan and did not leave.

"It's this kind of card that cuts off the connection between my consciousness, which is stuck in the central system, and the brain system." Xiao Yuan saw the old man's every move clearly through the lenses on his helmet, but this time he didn't connect to the central system, so the card didn't play his due role, Xiao Yuan didn't feel sad because of what the old man did to him, because he knew that the old man's mind should be confused by some kind of confusion at the moment, so it would be so abnormal.

However, Xiao Yuan didn't dare to delay too much time in the helmet, the old man's actions should be fed back into the central system immediately, and his consciousness was not there at the moment, the guy who was waiting there would definitely be aware soon, he had to take action before the other party reacted, and now rescue Tang Sa and the old crocodile to prevent the two of them from threatening him, and then go to the computing center at the bottom of the base to find that guy.

When dealing with that person in the central system, Xiao Yuan learned that although that guy occupied the central system, he was fully aware of controlling those vortices, and he still did not fully grasp the operation of the system, which was his advantage.

These thoughts flashed through his mind, and Xiao Yuan reacted quickly, just like in the training ground in Area 1, using nanorobots to invade the old man's body, destroying the normal contraction skills of his muscles, making him incapacitated, and dealing with the two people who entered the door with him, still using the method of spiritual resonance.

"You!" The old man saw that Xiao Yuan took off his helmet, revealing a face that he was extremely familiar with, with a shocked look on his face, and when he opened his mouth to call out a word, he found that he was speechless again, and the two soldiers who came with him also suddenly fell.

"Master, I'm sorry, I don't have time to talk to you for a long time for the time being, I'll come back to you when I'm done with the matter." Xiao Yuan didn't use nanobots to hide his face, the old man obviously recognized him, so he looked shocked, but at this time, he didn't have time to explain to the old man, so he could only leave such a sentence, stretched out his hand and put a few cards on the old man's body into his pocket, and came to the door, and the remaining few people who followed the old man outside the door were also stunned by him with the spiritual resonance method, dragged into the secret room in turn, locked the door with his backhand, and left the secret passage.

In the office outside, Xiao Yuan untied his father who was tied to a chair.

"It's fine if you're okay." Xiao Changtian was relieved to see that Xiao Yuan was fine.

"I learned a little about the base center system, and now I'm going to find Sister Sa and the old crocodile." Xiao Yuan said.

"How do you get there, they're on the seventeenth floor underground, and they're heavily guarded there." Xiao Changtian said.

Xiao Yuan said that he could go over, Xiao Changtian wanted to go with him, but he also refused, just let him stay here and take care of the old man, he left the thirteenth floor alone, and dived to the seventeenth floor underground, because Tang Sa and the old crocodile were going to be made into a human brain computing unit, and before making a computing unit, they would be imprisoned on the seventeenth floor of the basement and use various medicines and nutrient solutions to nourish their bodies.

After leaving Xiao Changtian's room, Xiao Yuan changed his appearance again, knocked out a researcher halfway through, changed his clothes, and walked into the elevator.

Go down to the fifteenth floor, Xiao Yuan came out of the elevator, and then go down, it is the core layer of the base, ordinary elevators can't go down, only through the high-level of the base, that is, Xuan Nie personally authorized to go down, of course, now Xuan Nie is sleeping, the base center system is controlled by Adam, so if you want to go down, you must have Adam's authorization, Xiao Yuan can't alarm Adam, let alone get his authorization, so he can only find another way, fortunately, his brain system stores a complete map of the entire base, So knowing that there is a very secret passage to go down, although it is a bit risky to go down from there, but it is better to be secret.

The downward passage is in a corner of the fifteenth floor, and to get there, you must pass through a military garrison area, which is very large, and there are thousands of elite soldiers stationed in it, and it is heavily guarded, Xiao Yuan can't use nanobots to get so many people at once, let alone swagger over, so he can only think of another way.

In a passage twenty meters away from the guard area, Xiao Yuan stood in front of a reserved system interface, released the nanobot, and used the nanobot as an intermediary to invade the central system of the base, in fact, more precisely, what Xiao Yuan did should be a normal login, of course, the login process is encrypted, unless he has the highest authority like Xuanne, others will not be able to find him, and Adam still does not have full control of the central system at this time, He found that Xiao Yuan's possibilities were infinitely close to zero.

About half a minute later, there was a sudden alarm of emergency assembly in the garrison area, and at the same time, there was a radio call asking all the soldiers to immediately assemble at the designated place, and after receiving the order, all the soldiers left their original posts one after another and ran quickly to the designated place, and the garrison area was in chaos.

Xiao Yuan blended in from the hidden area on the side of the garrison area, took advantage of the chaos to stun a soldier, dragged him to a corner, quickly changed into his clothes, passed through the garrison area without danger, came to the wall at the end of a narrow passage, reached out and warped on the wall, and then took out the dagger he carried with him and pried a hole in the wall, revealing a small black keypad.

Xiao Yuan entered a series of instructions on the keyboard, and when the wall in front of him slowly began to rise, revealing a black hole passage below, he was also relieved, the passage could be opened, indicating that Adam had not yet paid attention to this passage, nor had he changed the password here.

Walking into the passage, it was a spiraling staircase, Xiao Yuan walked forward one step, one step back, and then two steps forward, stood on that step and counted three seconds silently, took another step forward five steps, stopped for eight seconds, and walked forward thirteen steps, when he stepped on the thirteenth step, the whole passage lit up with a dim light, and the dark door behind him rumbled shut, until this time, Xiao Yuan walked down quickly with confidence, and the steps in front of him were actually a Fibonacci sequence, This sequence is contained in the number of steps and the time of stay, even if people who don't understand this rule can get the password of the secret passage, if they don't understand this rule, and rush down after entering, they will be instantly hit by the laser weapons in the secret passage and turned into ashes.

The passage is almost at the edge of the end, there is a door marked 02, from the inside to the outside, but there is no need to enter the password, Xiao Yuan held the handle of the door, twisted it a few times, and the door opened, outside the door is the penultimate layer of the entire base, the seventeenth floor underground, Tang Sa and the old crocodile are imprisoned on this floor.
