"Then you should tell me how to fight, right?" Li Yiheng touched the hot iron wall, and the air temperature here also increased.

Cheng Dong pointed to the lower right corner of the iron wall, where there were three inconspicuous finger prints, which were left by the reformers many times before: "Do you see there? Move that corner to the left, first upward, and then to the right when encountering resistance, you will hear the sound of the iron lock locking, and then to the right, and the door will open." ”

According to the method Cheng Dong said, Li Yiheng really raised the door up nearly two meters high, and heard a click, the iron door was firmly stuck, and a breeze blew in his face.

"This is a labyrinth lock, and you can't open it with brute force. Cheng Dong felt relieved when he encountered the wind, and the previous tension and heavy panting sound disappeared.

"Is he a phobia of claustrophobia?" whispered next to Li Yiheng's ear.

In this environment, no matter how small the voice is, of course, it will reach Cheng Dong's ears, but Cheng Dong, who was walking in front, ignored it and turned straight to the right passage.

Li Yiheng shook his shoulders, signaled Xiao Ji not to speak, and quickly followed Cheng Dong, just turned a corner, and bumped into Cheng Dong, Li Yiheng was just about to speak out, but saw a fence-type current network in front of him, opposite the current network, there was an electric prison, Li Yiheng and their location happened to be in the corner of the ground of the electric prison, it seemed to be a vent, but it was quietly dug up by Cheng Dong.

Li Yiheng walked to the position next to Cheng Dong, looked carefully, and then saw that there was a dull-looking little boy locked in the electric prison, who was sitting in the middle of the electric prison and stretched out his hand to draw something on the ground.

Li Yiheng knew that this was the electric prison where Diana and Tianhong were imprisoned, but why Cheng Dong dug up this position, this is not the first problem Li Yiheng faces, and in the current situation, it is the main difficulty to get into the electric prison.

"What do you do now? Go in directly, or do you have another secret way?" Li Yiheng couldn't help but ask when he saw Cheng Dongleng there, staring at the little boy in the electric prison motionlessly.

Hearing Li Yiheng's urging, Cheng Dong came to his senses, and took out a palm-slap-sized, concave in the middle, and thickened discus on both sides from his arms, and the discus was evenly embedded with beast-finger-like silver protrusions, I don't know what material, Li Yiheng counted it, there were six in total, all fingertips were pointing up, and I didn't know what to do.

I saw Cheng Dong directly throw the discus in the center of the fence-type current network, the discus received the stimulation of the current, and actually stopped moving, the dark yellow pop-up button in the center of the depression suddenly exploded, and by absorbing the power of the current network, the six silver-white "beast fingers" were driven to rotate slowly, and the same current jumped out at the tip of the "beast fingers" to connect with each other, and gradually expanded outward, and the discus that originally seemed to be one was also split from the middle, and all the small components were called "beast fingers" A hollow circle is formed for the nodes, which do not stop until they reach the edge of the current grid, thus opening a passageway.

"Hey, you still have this kind of powerful thing, I'm afraid it's your private goods, and you haven't shown it to your domain king, right?" Li Yiheng felt incredulous about this, and thought that Cheng Dong must have made more of this kind of tool in case he needed it.

Cheng Dong ignored Li Yiheng's blunt speculation, there was only a slight sound of electricity in the whole process, the little boy who was holding his fingers and was burying his head on the ground and kept writing and drawing was attracted by the sound of electricity behind him, and turned his head, the boy was only ten years old, and when he saw Li Yiheng, they didn't scream, but they whispered to Cheng Dong excitedly: "Dad, you're here." ”

"Dad?" Li Yiheng looked at Cheng Dong next to him in surprise, Cheng Dong's face also bloomed with a long-lost smile at this time, and he waved his hand gently at the little boy and said, "Xiao Ran, everything is okay? Dad has had too many affairs recently, and he has been delayed for so long, this time Dad is going to rescue you." ”

Saying that, Cheng Dong stretched out his hands forward and motioned for Xiao Ran to come over, Xiao Ran looked around, and crawled through the separated passage on his stomach, and was hugged by Cheng Dong and placed on the ground.

The boy named Xiao Ran was not surprised when he saw Li Yiheng, but asked Cheng Dong quietly: "Dad, why is there a bird on the shoulder of the transformer you brought this time?"

"What kind of reformer? I'm a normal person. Li Yiheng was very dissatisfied with Xiao Ran's bluntness, and at the same time, Xiao Ran's words verified his guess: Cheng Dong relied on transformers to open this tunnel for him.

"Alas, how could your son be locked up in an electric prison? How can you be a father?!" Li Yiheng asked Cheng Donglai.

Cheng Dong seemed to have planned to rescue his son for a long time, and until now he couldn't help but look around Xiao Ran to see if there was anything unusual, while Xiao Ran stared at Li Yiheng and Xiao Zhen, smiling from time to time, as if apologizing for his recklessness.

Cheng Dong held Xiao Ran's shoulders with both hands, the smile on his face retreated, and said to Li Yiheng: "Don't go and save your companions, ask these useless questions here, save some effort to escape and ask again." ”

Li Yiheng was speechless and asked Xiao Ran: "Did you see that the two beautiful sisters were also locked up here today?"

Xiao Ran pointed to the left side of the separated passage and said, "They're locked up over there, but it's a long way from here. ”

Li Yiheng poked his head out and tried to stretch out his neck to look to the left, only to see that at the end of the left side of this electric prison, Diana and Rainbow curled up in a black and red electric prison around them, and the black looked extremely domineering, and it should not be so easy to break through.

"It's strange, why aren't there any guards here?" Li Yiheng asked the two people beside him, and asked Xiao Ran more, since Xiao Ran has been trapped here for a long time, he will always be familiar with the situation here.

Cheng Dong was not surprised: "These people are very confident in this electric prison, and no prisoner has been able to escape from the electric prison", and then the corners of Cheng Dong's mouth twitched, and continued: "This is also before you came, so the domain king never arranges soldiers to guard, but there are a few people outside this electric prison who are responsible for the daily life of the prisoners here, but I didn't expect that his arrogance has reached this level." ”

Li Yiheng knew that what Cheng Dong said meant that he had torn the floor in the prison and escaped before, which also failed to arouse the vigilance of the domain king, and if Li Yiheng escaped with Diana and Rainbow this time, it should always touch the domain king's new view of the electric prison.

Cheng Dong took out a similar discus from his pocket, but it was slightly larger than the previous one, and there was a small sieve-like net pocket in the center of the depression, which was pitch black inside, and I don't know what it contained.

"Use it, the same way as I did, throw it on the current wall, and you can get them out, the sooner the better, I'll only wait here for you for five minutes, and when the time comes, I'll go back, don't blame me for not being benevolent enough. Cheng Dong handed the discus to Li Yiheng.

Li Yiheng took it in his hand, looked back and forth, Xiao Ji also leaned out his neck to observe, Xiao Ran interjected and said: "This is called 'pushing thunder away, but it is the proudest thing of my father.'" ”

Cheng Dong heard his son's praise, or in front of outsiders, and a slight smile unconsciously appeared on his face, which was fleeting.

Holding a push thunderbolt in one hand, Li Yi slammed up the wall horizontally, and quickly drilled out of the open passage like a loach, first using the push thunder to break through the current fence of Xiao Ran's cell, and then took it down, and walked quickly towards the cell where Diana and Tianhong were.

The surrounding area is densely built like a lattice box, just like the prison field, except that the walls of the electric prison here are made of two different colors of electric currents spaced through, blue and white, purple and white, red and blue, and there is a room like the one where Diana and Rainbow are, which is red and black.

Li Yiheng knew that he could identify the energy contained in the thunder and lightning by the color of the thunderbolt, and thought that this current should be the same as the thunderbolt, and through the energy difference between the currents, they naturally formed a magnetic field, which invisibly formed four walls, which made it more reliable.

Whether it is a person inside or outside the prison, as soon as he touches these current walls, he will not only be subjected to electric shocks, but also will be attracted by the invisible magnetic field, which is interconnected with the magnetic field in the human body, which makes the power of the electric shock even heavier, no wonder the domain king will be so relieved about this, it is not without reason, if it is a person like Li Yiheng who does not know how to use electricity, it is easy to be trapped by this current wall, but when he meets a genius like Cheng Dong, it is a disaster for his own family.

There were prisoners scattered in these electric prisons, Li Yiheng thought of how many people should be caught by the domain king for experiments, these people were men and women, and watched in amazement as Li Yiheng walked quickly through the aisle between the two rows of electric prisons, and no one made a cry for help.

Li Yiheng came to the electric prison where Diana and Tianhong were, they were leaning on each other, sitting on the ground in the center of the electric prison, seeing Li Yiheng, Diana almost jumped up happily, just about to approach, but when she saw the current wall, she took a step back tabooly, and it seemed that she had suffered from electric shocks.

"I'm sorry I'm late. Li Yiheng said, and threw the thunderbolt to the high position of the current wall, and the red and black current was instantly connected to the thunderbolt, and the same as the first one, the six "beast fingers" of the thunderbolt began to move slowly, and many components diverged, but it seemed to have no effect on the black lightning, and the divergent components did not expand outward, no different from a discus pasted on the wall, and the channel was not opened.

Li Yiheng was puzzled, looking in the direction of Cheng Dong's hiding, the hollow net pocket in the middle suddenly opened upward, and the black graphite particles the size of rice grains inside were attracted by the magnetic field of the thunderbolt itself, like a beetle climbing out one by one, covering the edge of the "beast finger", connecting in a circle, the black current touched the graphite circle, as if the spider's web was burned by a torch, and quickly contracted as the graphite circle approached, and finally formed a channel more than one person high.

Diana and Rainbow were also stunned by this thunderbolt function at first, but when they saw that the passage was opened, they immediately ran out, and Diana stepped forward and hugged Li Yiheng and cried: "I thought I would never see you again, leaving us behind, you ran away by yourself." ”

Li Yiheng stretched out his arms a little at a loss, not daring to touch Diana, and looked at Tianhong on the side embarrassedly, as if he was really asking Tianhong for help.

Rainbow understood, patted Diana on the back and said, "Okay, such a greasy thing is waiting for you to hug enough, now we have to run away quickly." ”

Only then did Diana let go of Li Yiheng with tears in her eyes, and pushed him with disgust: "Take us away!"

Li Yiheng was relieved, not in a hurry to leave, and asked where was Tianhong Shixiong Pass?

Rainbow shook his head: "When I was brought here, I had to go through the most central corridor, I paid attention to all the electric prisons, and I didn't see Shi Xiong, so I should have been locked up somewhere else." ”

At this point, Li Yiheng slapped his head three times as if blaming himself, and Tianhong was quite moved when he saw this scene: "It's not your fault that you can't find others, why harm yourself? It's really hard for you to come and help me." ”

"I'm not self-harming, we should have asked Cheng Dong about Shi Xiong's whereabouts, he said before that Shi Xiong was taken away by the reformers, but because we encountered too many things later, we forgot about this stubble. After Li Yiheng finished speaking, he led the way in front and ran in the direction of the tunnel with Diana and Rainbow.

The people around the electric prison got up one after another, and now the center of the electric prison looked at Li Yiheng and them, and they didn't make a noise, nor did they ask for help, everyone's eyes flashed with relief and longing, and they were also eager to escape, but without exception, they didn't say it, because they knew that they would not be able to let the young man in front of them take them all away, the more people, the greater the danger.

Tianhong looked at the people in the electric prison around her, and through her special induction of Leilis, she knew that all the people locked up here were Leilis, most of them were young adults, and there were also many old people.

Rainbow suddenly stopped and said to them: "I, Rainbow from the mountain town, if I leave here safely, I will definitely save everyone out." ”

Li Yiheng and Diana, who were running in front, also stopped, and looked at Tianhong guiltily, Li Yiheng had to do this, because Cheng Dong didn't have much time left for him, and it would take a lot of time to save the people here, and everyone would not be able to leave at that time.

Rainbow solemnly gave a military salute to the imprisoned Lelis, and then decisively ran to Li Yiheng, the Lelix in the electric prison were given a lot of hope by Rainbow's words, and their expectant eyes became more determined.
