Ji Qi's eyes briefly glanced at Chu Yu's hiding place, and then looked away. But even so, Chu Yu was shocked into a cold sweat. Now, he knew that Ji Qi must be hiding something from him. , and if he was discovered here, would Ji Qi choose to silence him? Chu Yu retracted his body into the cave. Recalling what he had just seen, many doubts arose in his heart. He didn't understand why Ji Qi came here with those heavy machines, and Nie Guichen. He seemed to have some doubts about it. Ji Qi knew everything he had done. Wasn't Nie Guichen in the alliance? When did he come here? Recalling the previous conversation between Li Daoling and Li Daozi outside the Sin Domain, Chu Yu knew that the reason why Nie Guichen was here now was probably because of the reinforcements brought in from the Taoist sect. The Taoist sect asked Nie Guichen to come to the Sin Realm, probably to save Zhang Yitong and himself. Now that Nie Guichen appears here, what about Zhang Yitong? The reason why Chu Yu came to the Sin Domain again was to find Zhang Yiyi, but now not only did Zhang Yiyi not find him, he was also trapped in the Sin Domain. Judging from the situation just now, Nie Guichen obviously knows the situation in the Sin Territory better than anyone else. Has he rescued Zhang Yiyi now? Chu Yu knew that this possibility was very high. If Nie Guichen rescued Zhang Yiyi, why didn't Nie Guichen save himself? Let yourself fend for yourself within the formation? Leaning against the stone wall, thinking about these questions, Chu Yu couldn't think of an answer. Because he didn't know the secret between Nie Guichen and Ji Qi, Chu Yu didn't dare to go out rashly. If he had to choose, he would rather go back to the outside of the sinful realm now. , but although he entered the formation of the Sin Domain, he was not very sure about how to get out. If he went out rashly and fell into the formation again, Chu Yu would not dare to bear such a result, and he would not be able to bear it. After staying in the cave for about ten minutes, Chu Yu stretched his head out of the cave again and looked at the robot factory below. Ji Qi had disappeared from the stone bridge. Chu Yu looked down and found Ji Qi as far as he could see. The existence of Ji Qi is unknown, and the stone door that Nie Guichen walked into before has not been opened yet. Nie Guichen should still be inside. After watching for a while, Chu Yu finally understood the reason for the roar of so many machines here. It turned out that this place could be said to be a small robot processing factory, and robots were being assembled here. Why is Ji Qi assembling robots here? Isn't he willing to be expelled from the Federation? Looking at those large machines, Chu Yu couldn't help but frown. If Ji Qi moved all these things here within three days, Chu Yu would never believe it. If not, he could only say that Ji Qi and Nie Gui Chen had already been in contact with him, and before Bai Qianchi decided to attack Ji Qi, Ji Qi had already found a way out. There is only one explanation for the matter, but what is Nie Guichen's purpose in doing this? And why did Ji Qi build so many robots? Thinking of this, Chu Yu quickly rejected his idea. If robots were to be made, Ji Qi would not be welcome in the federation. Since Nie Guichen agreed, Ji Qi could definitely go to the alliance. There was no need to come here. After all, this is the Taoist forbidden area. , it is very difficult to avoid the eyes and ears of Dao Sect. But now Ji Qi has not only moved the robot manufacturing factory here, but is also manufacturing robots here. What is going on here? Apart from anything else, how could there be a power source to power the machine here? Obviously, the final answer may be behind the stone wall that Nie Guichen entered before. Looking at the stone wall, Chu Yu was silent for a moment, then turned around and retreated into the cave. Back in the cave, Chu Yu did not move around and began to practice exercises to restore his strength. Time passed quickly. When Chu Yu woke up from trance, three hours had passed since he entered the cave. When he opened his eyes, Chu Yu He found that the roar of machines coming from all around had disappeared. When he stretched his head out of the cave to look at the scene below, he found that it was pitch black below. Except for the button lights of some parts that were on, the searchlight in the center of the field had been extinguished. After looking at it twice, Chu Yu turned around and lurked secretly below. It had been a week since he entered the Sin Realm. This week, because of the Tianming Pill, he didn't feel that he was very hungry, but his body had already Seriously short of water, he wanted to find something to drink. When he came to the flat ground below, Chu Yu found that the open space here was much larger than he had imagined. Fortunately, those robots did not know where they had gone. Chu Yu was not too worried. While looking for water, he found that now It was already two o'clock in the morning. Chu Yu didn't know the date or how long he had stayed in the Sin Domain. After finding the water source, Chu Yu unscrewed the water pipe and drank some. The clear water went into his stomach. Chu Yu felt his body relaxed for a while. He sneaked around the simple factory for a while. Chu Yu found that many robots in production had been stored here, and some had already been produced. The finished product, looking at the robots standing in the open space, Chu Yu didn't know how Ji Qi injected consciousness into these robots. Could it be that the origin of computer chips??, Chu Yu thought, looking up at the stone bridge above his head. Nie Guichen disappeared on the other side of the stone bridge. Is Nie Guichen still here now? Chu Yu decided to inquire about it. He looked around and then climbed up the stone wall towards the stone bridge. Soon, Chu Yu came to the stone bridge. When he came to the place where Nie Guichen disappeared, Chu Yu Yu was stunned on the spot. Nie Guichen seemed to have touched some mechanism before, but because the distance was too far at that time, Chu Yu couldn't see clearly. He didn't know what Nie Guichen did on the smooth stone wall. Now Chu Yu came When I got to the stone wall, looking at the smooth soldiers, I felt like I had nowhere to start. After standing in front of the stone wall and looking at it for dozens of seconds, Chu Yu reached out and touched the stone wall. His hands were cold and did not look like there was any mechanism. Just when Chu Yu decided to leave, a strange sound suddenly came from the stone wall in front of him. Hearing the sound, Chu Yu was startled. He knew that the stone gate was about to open. He glanced left and right, turned over and came to the stone bridge. He ducked and came under the stone bridge. He grabbed the bulge under the stone bridge with his body, like a It clung to the stone bridge like a gecko. The people who walked out of the stone gate were Nie Guichen and Ji Qi. The two came to the stone bridge. Nie Guichen looked at Ji Qi and said, "I'll leave this place to you." "Now that the Taoist sect knows I'm here, they I'm afraid they'll be here soon." Ji Qi asked worriedly. Nie Guichen chuckled lightly: "Don't worry, they have been thinking about coming in for thousands of years, haven't they been successful?" Nie Guichen said for a while: "If I didn't lead the way, they wouldn't have found this place. " Ji Qi nodded: "That puts me at ease. " " Just stay here and wait for my news. " Nie Guichen said and walked towards Shiqiao Ling. He planned to leave. After taking two steps, Nie Guichen, who thought of something, looked back at Ji Qi and said, "By the way, Chu Yu has entered the sin zone. I looked for him before but couldn't find him. He may be trapped in the formation. If he can It's best to stay in the formation. If he happens to come here, I think you should know what to do." Ji Qi nodded and said nothing. After Nie Guichen left, Ji Qi stood on the stone bridge for a while, then turned around and walked towards the stone gate. After taking just two steps, he stopped when he noticed something and looked back at the person standing on the stone bridge. people. Chu Yu heard clearly the conversation between Nie Guichen and Ji Qi just now, especially the last paragraph. The purpose of Nie Guichen's hope that Chu Yu would stay in the formation was to prevent Chu Yu from disrupting his plan. Nie Guichen would rather Chu Yu die. If Chu Yu came here, Nie Guichen also gave Ji Qi an explanation, that is, let Ji Qi deal with Chu Yu. Now that Nie Guichen has left, Ji Qi wants to enter the stone gate. Chu Yu thinks about it under the stone bridge and decides to take the risk. He wants to talk to Ji Qi and see what kind of medicine Nie Guichen sells in his gourd. And even if he doesn't show up, if he keeps waiting here, it's still a question of when he can leave the Sin Realm. Therefore, just when Ji Qi was about to enter the stone gate, Chu Yu turned over and came to the stone bridge. Seeing Chu Yu, Ji Qi didn't look surprised. Instead, he said with a smile: "You came here earlier than I thought." "I want to know what's going on." Chu Yu said. Yu said bluntly that he didn't want to make any circles with Ji Qi. "What do you want to know? I can tell you." Ji Qi said for a moment: "But before that, I still have some things to do. Can you wait for me?" Chu Yu remained silent without saying a word. Chu Yu didn't speak. Ji Qi took it as Chu Yu's acquiescence. He turned sideways and continued to Chu Yu: "You can wait for me here now. I'll be back in ten minutes at most." After saying that, Ji Qi turned to Shi Qiao. Walking to the other end, when he came to Chu Yu's side, Ji Qi said to Chu Yu: "You are really lucky." Are you lucky? Listening to Ji Qi's words, Chu Yu didn't think so. A word suddenly appeared in his mind, life is thinner than paper. At this time, Ji Qi had already walked past Chu Yu. Chu Yu looked back at Ji Qi's back and walked towards the stone gate. After entering the stone gate, the first thing that caught the eye was a large and sophisticated machine. There were many light spots flashing on Ji Qi. In addition, there were many buildings that Chu Yu couldn't name. They looked like It was a large palace with two east and west corridors on both sides of the stone gate. The corridors were brightly lit and it was unknown where they led. Seeing this, Chu Yu became more determined - the things here were not built overnight at all. From Zheng Duancheng's words, Chu Yu learned that Ji Qi had self-awareness for a short time. It should take about a year. Within this year, it is obviously impossible for Ji Qi to build an underground world of this scale. Could it be? Nie Guichen? People from the Taoist sect have been unable to enter the Sin Realm. Only Nie Guichen can do this. However, it is impossible for Nie Guichen to build this underground world with the power of one person. Even if there are tens of thousands of people here, Build at the same time??It may not be possible to build it even if it takes only a few years Thinking of this, Chu Yu thought of a possibility - are these things the relics left by the last civilization? Chu Yu came to the central machine and started to check it. He found that these machines did have some ideas, but Chu Yu couldn't understand. If these machines were really left behind by the last civilization, how could they still be running now? These things were beyond Chu Yu's knowledge. When Chu Yu saw a chair beside him, he sat down and waited quietly for Ji Qi's arrival. Since Ji Qi could tell him anything, he would probably be able to untie it soon. The answer. Ji Qi said he would be back in about ten minutes, but in fact he only left for five minutes. When he came back, he had a map in his hand and saw Chu Yu sitting on a chair waiting for him. Ji Qi smiled at Chu Yu He said: "Chu Yu, I didn't expect us to meet so soon." "I want to know what's going on here and the robots outside." Chu Yu said for a while, then stared at Ji Qi and said: "Nie Guichen said Do you want me to kill you when you see me? Even if you want to do it, I hope you will tell me everything and let me be a sensible person, okay?" Ji Qi nodded: "I will tell you the truth." Ji Qi opened his hands, pointed at everything around him and said to Chu Yu: "Chu Yu, take a closer look at this place. This is the relic left by the last civilization."
