Some elders instantly hugged the children, and the old people also closed their eyes and said something in their mouths.

This scene made Zheng Kai, Bi Min and Luo resolutely tremble, and as far as they could see, there was a belt of gravel dozens of kilometers long suspended dozens of meters above their heads, floating slowly like this. These rubble, which are usually difficult to clean up by robots, and the garbage that cannot be disposed of temporarily in life, were obediently transported out of the city under the control of Bing Shijue.

"I'm just helping you clean up some garbage along the river." With a flick of his finger, the muddy black gravel ribbon floated away from the city and landed in some areas outside the city, killing the beasts and strong acid flowers that wanted to flee by the way.

"It's basically solved." Bing Shijue stepped on the solid ground, and he was a little unable to adapt for a while. For the past two months, he has been suspended in the debris of four-dimensional space, and before that, he had galloped back to Yanjiang City from the sea area of the equator, and there was almost no stop on the way.

"You've grown to this point." Zheng Kai just estimated the move of Bing Shijue, and knew that the people in front of him, whether Bing Shijue or not, did not need to do anything to them, this sense of powerlessness was like knowing the level of technology possessed by the Starry Sky Sect, and the moment when it was compared with their technological level, "Bi Min, give an order, don't be vigilant anymore." ”

"Understood." Bi Min also shook his head slightly at the person behind him, and raised his hand to signal that he could cancel the aim. Soon, Bing Shijue felt that the feeling of being watched disappeared, and the soldiers within the range of Divine Perception also put away their guns, and instead looked at Bing Shijue with curiosity.

"It's only been three months since you left Yanjiang City, and the changes are so big." Zheng Kai looked at the somewhat gray sky at this time, "It's already autumn." ”

"Winter is coming." Bi Min stepped forward, and Luo Yiran on the side continued to let people live on the ground, and began to distribute some compressed biscuits with the logistics department, as well as count the planting of farmland on the outskirts of the city.

"But spring will come." Bing Shijue looked at the city along the river after a three-month absence, and found that the city had changed too much, even more drastic than his own.

The refugees in the picnic area were accepted by the riverside city, and although they were sick, they could provide a good labor force to a certain extent. And after being in the picnic area for so long, although I live in the periphery and don't have much technology, I always have better technology than those in Yanjiang City.

The most deadly thing is that after the previous city was breached, a large number of elderly people died, and some middle-aged people in their forties and fifties also suffered from diseases and had no way to participate in the construction.

He has only changed his strength, but the population organization and life pattern of the city along the river are different from before. The robots that were originally rejected by people are now equipped with one in some old and young families. There are also those who follow the team behind Luo Yiran, which are the more rugged robots that are responsible for handling.

At the same time, the excavation of the underground has reached 17 kilometers, and some of the basic facilities of the underground city have been completed. Nowadays, the underground is also responsible for the delicate digging, and it is also a mechanical spider that Bing Shijue has never seen before, and a control room on the ground is in charge.

"By the way, I'm here for a big deal." Bing Shijue looked at Zheng Kai, who had kept a little distance from him, and said in his mind, still in Bi Min's mind, "Aliens have 43 years to reach the earth. ”

"What's ......" Zheng Kai almost didn't move steadily, he stumbled, and Shen Zixuan on the side helped him, while Bi Min also stayed in place, looking at Bing Shijue blankly. Bing Shijue, on the other hand, could instantly detect the changes in the mood of the two people from their rapid breathing and the chaotic thoughts in their minds.

"Looks like you've gained a lot." Zheng Kai calmed his rapid breathing and looked around at the houses around him that were being built with the assistance of robots, "Arrived after 43 years. ”

"If the information I got was correct, I think the Star Sect should have known about it, but the information they got shouldn't be as accurate as mine." Bing Shijue said that he had just finished listening to the topic of people chatting in this city, and by the way, he took the time to search for other cities, but he still didn't find where his parents were, "Zheng Kai, do you know where my parents are?" ”

"Yes." Zheng Kai closed his eyes in pain, his knuckles against the corners of his eyes, "I have to digest what you just said, Bi Min, you called Luo Yiran here." Shen Zixuan, you called Xia Xiaoyan and Huang Jia over. During this time, I went to the managers of other cities and told them the news. ”

“…… Then, Ice Awakening, your mind should be able to know that there is a storage space underground. As Zheng Kai spoke, he stretched out his fingers, pierced into his hair, and scratched hard, "There is a spar similar to a clover underneath, behind a muddy green slime, that thing records the life information of your parents, as long as the clover is still bright, your parents are fine." ”

"Because I have been a manager for a short time, and they die very quickly when I become the director, because the offensive and technological level of the picnic area is too much higher than ours, and I really don't know a lot of things." Zheng Kai let out a long breath, "Three hours later, at six o'clock tonight, we will see you on the first floor of the basement, 3 kilometers underground, it should be enough for you to find your parents." ”

"Thanks, I'll be back soon." The blade that had been hanging high in Bing Shijue's heart for three months finally calmed down a little, and as soon as his mind moved, he instantly came to the entrance of the dungeon, under the huge black tower, slid through the gap, and then came to a small underground square that was generally unfamiliar, but there was still a hint of familiarity.

Overhead, the pure white ball was still levitating. It's just that now it has been transformed into a robotic functional device with other equipment. It seems that a magnetic field is created with levitation, and the magnetic field creates an electric current, which supplements the energy of these underground robots.

The divine thoughts shook slightly, and Bing Shijue captured the white sphere, but now, he could still sense that the white sphere was slowly absorbing the surrounding energy, and it was also absorbing his own divine thoughts, but it was very small.

Moreover, he still couldn't penetrate the divine mind into the sphere to see what it was.

"Marbles of a third-level civilization? Cannonball? Something in some of the core devices. Bing Shijue didn't think much about it, because he didn't feel any threat from the white sphere, so he quickly followed the picture he saw in his thoughts, and gently suspended in the still digging passage, all the way down, to a tunnel mouth that he was not familiar with.

"This must be the place where I researched before." In just a few seconds, Bing Shijue flew thousands of meters underground, and he was used to using such a fast speed. I was also accustomed to sweeping the incomprehensible mathematical formulas or guesses on the walls with my divine thoughts, and I also glanced at the alien objects that had lost their energy and were completely abandoned for research.

In a short time, he came to the end of the tunnel, and saw the puddle of lifeless slime, and the huge hedron that he envied so much, but he did not dare to touch. When he was in the air along the riverside city, he noticed that the energy supply in some places was done with hedrons.

If he touches it now, I'm afraid he will be able to absorb these hedrons in an instant.

"Found it." Bing Shijue carefully walked through the hedron tunnel and saw a safe at the end. According to his observations, he found that under several layers of thick metal, there were thumb-sized clover-shaped mechanical flakes, and these three mechanical flakes were slowly shrinking and relaxing, and the veins of the leaves were flowing as if they were alive.

"It seems to be fine...... Bing Shijue's face finally showed a relaxed smile after three months.

He stretched out his hand, and at a distance of a few meters, as if tearing through plastic film, the safe was torn open, revealing the fine clover inside.

"I guess it's my parents, but who is the other one, Bai Qiuyue?" Bing Shijue carefully observed the agitation of the three leaves, closed his eyes, and his divine thoughts wrapped around the leaves like filaments, to feel where the source of this agitation came from.

In an instant, Bing Shijue felt that his body suddenly passed through a long space and time, as if he had entered a four-dimensional space, but more gently. Later, he noticed that a clover had appeared inside his sea of knowledge, and the leaves had begun to change, as if to guide the way.

"North?" Bing Shijue opened his eyes and was sure that his sea of consciousness space contained this clover, and then as long as his mind moved, the clover appeared in front of him again. And always point in the direction of the north.

"Just go check it out." Bing Shiju's body was slightly suspended, slid through the underground tunnel, and then quietly rose into the sky, and the whole person flew happily in the gray sky. After he left Yanjiang City for a while, he instantly soared beyond his extreme speed, emitted a piercing sonic boom, and rushed to the north.
