The three of them stood in the dark doorway and looked up at the top of the tower, the street was deserted, and some pipes were still spewing the steam and some hot water from time to time.

"I really can't see it from above, this tower is nearly two hundred meters high, you say, what is the mechanical frame in the tower used for?" Li Yi set up a pergola with his crossed hands, tried to look at the top of the tower, and asked Diana and Tianhong.

Tianhong does not have the mentality of Li Yiheng, she is anxiously looking around, looking for a place to hide, better like, it would be best if she could have a bed to rest, but she knew that the most important thing at the moment was not to be caught again.

Seeing that the two of them didn't respond, Li Yiheng knew what they thought, and persuaded: "Don't worry, with me, there is nothing that can't be done." ”

"Really, then you can take us to find a place where we can rest, we really can't run. ”

Diana replied angrily.

"That's not easy, wrap it around me. Li Yiheng pretended to be full of confidence, and glanced around in embarrassment, there was not a sign that said "accommodation", or what looked like a hotel building.

Li Yiheng walked in front again, now he is most worried about Xiao Ji's injury, he has never seen Xiao Ji have the current situation before, sleeping for so long, the outside world is so noisy and has not woken him up, Li Yiheng is afraid that Xiao Ji will fall into unknown injuries.

"Diana!" Li Yiheng said suddenly.

"Huh?"

"It's not that I don't trust your medical skills, can you help me take a look at Xiao Ji's condition again, he hasn't woken up yet, will something go wrong?" Li Yiheng asked worriedly.

Diana looked at Xiao Ji in her hand, slept soundly, and put her hands together for a while, and told Li Yiheng: "It's okay, Xiao Ji's ability is like this, the more serious the injury, the longer he sleeps, this is his own self-healing ability, and there will be no danger." ”

"Then I'm relieved, if anything happens to you, I really don't know what to do. Li Yiheng's seemingly relaxed answer was actually a serious emotion in his heart, and he was now inseparable from Diana and Xiao Ji.

As he was talking, the rumbling sound of thunder presses came from far and near, and Li Yiheng knew that it was the chasing army's thunder truck patrolling nearby, and there should be two more of them.

Rainbow was a little panicked when she heard the voice, and held Diana's hand tightly: "What now, they are chasing after them, let's hide in the tower again." ”

Li Yiheng knew that if he hid in the tower, he might expose these children, and since these children were hiding so secretly, they must be hiding from some people.

"I can't go back, it's going to be dangerous for those kids, and I have a way. Li Yi jumped onto the open pipe in front of him, and hid with the steam that spewed out from time to time, looking for the position of the pursuers.

There are welded narrow nozzles on the pipeline every other distance, and steam is sprayed out from these nozzles from time to time, Li Yiheng dodges the steam that comes out of the cold, looks for the direction of the sound, and sees that the same pipe is also erected on the adjacent street, through the gap between the pipes, Li Yiheng sees two thunder trucks are moving in this direction, each car is sitting with two people, and the two lightning pressure pipes at the rear end of the body are jumping out of faint electric sparks.

Li Yiheng leaned over to avoid the inspection of the pursuers, slowly climbed to the corner in front, waited for the opportunity to wait for the thunder truck to approach, and waited until the second thunder truck drove by, taking advantage of the gap between the two thunder trucks to spew steam, Li Yiheng jumped in, quietly and quickly concentrated the back of the two soldiers' necks, knocked them unconscious, and successfully snatched the brake power of the thunder truck.

Diana threw out the spore filament wrapped around the pipe above her head, grabbed the rainbow and flew up, just in time to see the first thunder car passing by, Diana pulled out her bow and arrow, aimed at another car faintly in the steam behind, and was about to release the arrow, when she found that it was Li Yiheng, and there were two fainted soldiers lying in the back seat of the car.

Li Yiheng suddenly increased his horsepower, and the two demining tubes behind the car burst out with two violent electric columns, crashing into the thunder truck in front.

The two soldiers in the front car were searching intently, and did not notice Li Yiheng's attack in the rear, and it was too late to hear the sound, Li Yiheng had already picked up the pipe on the right, and before the soldiers in front could react, the two cars collided together, twisting into a ball in an instant, and the three soldiers were squeezed beyond recognition, and one soldier was thrown out of the car and hit on a pipe.

The two thunder trucks, which had been scrapped metal, crackled with electricity, and the sturdy depressurized tubes were deformed and lost power.

Li Yiheng walked behind Diana and Tianhong, and said ostentatiously: "How about it, I didn't disappoint you, I did what I said." ”

With a "whoosh", Diana shot an arrow that hit the soldier who threw out, and when Li Yiheng looked over again, the soldier had already run a distance at some point, but fortunately, Diana was quick and did not let him go.

Diana squinted at Li Yiheng and said mockingly: "Cut, be careless, the one who doesn't die is the biggest scourge." ”

"You talk a lot. Li Yiheng complained, turned over and got off the pipe, "Let's go, find a place to rest." ”

Diana and Rainbow glanced at each other helplessly, self-explanatory, and followed, and after Diana landed on the ground, she used the spore to probe again, and found that there was no movement of other vehicles nearby, so she was relieved.

The trio crossed the current street and turned left into a more secluded path, where the ditches on either side of the path were piled up with an unnamed slimy black liquid, like asphalt, but with a fresh fragrance.

Li Yiheng picked up a dead branch and stirred the black slime, pulled up a piece of silk thread, put it under his nose and smelled it, the aroma was very light, Li Yiheng remembered that when he was in Cheng Dong's test ground, he saw a glass tube on the table, which was also black, it should be this kind of thing.

"What, you're so fascinated?" Tianhong asked after looking at Li Yiheng without speaking for a long time.

Li Yiheng threw down the branch and said, "These should be some kind of production waste in Lightning City, but they were discovered by Cheng Dong to have a more hidden value. ”

"How do you know?" Dianna wondered.

"Cheng Dong has this fragrance on his body, and when he was fighting with those two reformed people in the valley, and when he was caught by them in the Death Zesha Realm, I smelled this fragrance on them, and the situation was urgent at that time, and I didn't think about it so much, and now that I am connected, it should have something to do with Cheng Dong. Li Yi walked sideways and analyzed, and came to a door full of garbage.

Li Yiheng suddenly paused, pointed to the door and said, "Let's settle here." ”

Diana and Rainbow couldn't keep up with Li Yiheng's thoughts, and agreed that there was no eye-catching sign on this door, how do you know that this is a place to rest?

Li Yiheng stepped forward and began to knock on the door, the door opened, and Cheng Dong's head poked out, which surprised Tianhong and Diana a lot.

Cheng Dong opened the door completely, looked around, found that there was no danger, and said with a smile: "It's fast enough, it's not half a day's work, it seems that I still underestimated you before." ”

Tianhong asked Li Yiheng puzzled: "What's the matter? Why did you turn around again?"

Cheng Dong turned sideways and motioned for them to enter the door: "This is my house, I didn't turn back, please come in." ”

Rainbow was reluctant at first, Diana kept poking behind her, and Rainbow reluctantly followed Li Yiheng in, and after the three of them entered, Cheng Dong looked around again to make sure that someone else was following before closing the door.

The interior of the house is also very messy, and in the innermost part there is a large lattice table that can be lifted, and each lattice is a small room with beds and other items, like a small hotel that can be lifted.

Li Yiheng stopped in front of the lattice elevator and praised him: "Are these also your own inventions? It's really not too much to call you a genius." ”

Cheng Dong pulled the switch on the wall, and the lattice elevator was lowered one square, and a neat room appeared, "You can rest in it, and it is absolutely safe." ”

Rainbow couldn't hold it back any longer, and asked, "Did you think that we would come to you?" or did you design all this? ”

No matter how much Rainbow scolded Cheng Dong before, Cheng Dong didn't fight back, and this time it was the same, Cheng Dong just smiled, and Li Yiheng picked up: "It's very simple, when we come out of the tower, there is only one way to go, and those black things are also signs that guide us here." ”

"But", Li Yiheng changed his words and asked, "You can easily calculate where we landed, how do you know that we will definitely find here?"

Cheng Dong sat on the messy table and said: "I'm not just good at machinery, I also see people very accurately, the first time I see you, I know that you are not mortal." ”

"It's too exalting me, you must know about the children in the tower?" Li Yi diverted the topic, trying to get the information of the six children in the tower.

Cheng Dong was a little strange: "I didn't know there were children inside, that tower has been abandoned for a long time, and no one wants to go in." ”

Diana asked, "But we saw a poor child in there, like wandering, and besides, there was a ......."

"There's also a mechanical frame that doesn't know what it does, that's what you should know. Li Yiheng immediately interrupted Diana's words, afraid that she would say that girl next, since Cheng Dong didn't know, it was better not to say it, so as not to have other things.

"That mechanical rack was built by the ancestors of Lightning City under the help of an outsider, and I heard that it was to draw more effective energy from thunder and lightning, but for some reason it was not completed, so it was abandoned somewhere. Cheng Dong replied.

I'm also an outsider, so is this outsider like me and doesn't belong to this world? Li Yiheng pondered: It seems that more information will be collected here.

"Okay, since you can find me here, it's also fate, just stay here, if you need anything, just tell me, I'm next door", Cheng Dong walked to the lever on the wall, "If you want to change rooms, just pull this, there are also in the house, turn off the switch in the house before going to bed, it will block this lifting house." ”

"Uncle Dong?" asked Li Yiheng as he lay on the bed in the hut.

"What's the matter?"

"It's still the same old question, why help us?"

Cheng Dong pondered for a while, and said slowly: "Helping you is also helping me, and helping the residents of the entire Lightning City." ”

Diana clicked, pulled the switch, and the room where Li Yiheng was went down, and a new room appeared on it, and Tianhong and Diana went in to live.

"Really, what a mystery. Diana grumbled.

Cheng Dong smiled helplessly and walked to the small laboratory next door.
