Ding Chen's beautiful vision was not realized in the end, and the protagonist's aura played a role at the critical moment, when Ding Chen connected the chipset power supply directly to the input of the three-core cable control module, he heard a low buzzing sound. Pen ~ fun ~ pavilion www.biquge.info

Hearing this sudden sound, Ding Chen knew that something was wrong, this was definitely not the sound of opening the door, so he jumped up like a rabbit with an arrow in his knee, ran away, took out the ability of the armored infantry to board the car in three steps, and got into the room where Uncle Potato and Kiki were hiding in a few steps.

This office has not been damaged, so the furnishings inside are complete. Uncle Potato had a leg injury and couldn't stand for a long time, so he sat down directly on the sofa by the door, not caring about the thick dust on it. Kiki couldn't hold her breath after all, and leaned at the door to peek at Ding Chen's sled door. Suddenly seeing Ding Chen turn around and run over, she hurriedly dodged away and let Ding Chen in.

After Ding Chen got into the house, he didn't close the door with his backhand, just like he said to Uncle Potato just now, this door can't be opened from the inside, if it is closed, he will honestly smash the glass with a hammer.

He stretched out his hand to the door and listened carefully, and felt that there was no special sound in the corridor, so he felt a little relieved, so he carefully probed out.

Except for the buzzing sound, there was nothing unusual in the corridor, the battery light he used to illuminate just now was still on the ground, and under the light it emitted, although it could not be said that there would be any chance of appearing in the corridor, at least there was no blind spot at all, so Ding Chen could be sure that there was nothing here.

He turned his head to look at Uncle Potato suspiciously, and found that Uncle Potato was also looking at him. The two exchanged glances, and Ding Chen motioned for Qiqi to stay away, and slowly pushed open the door to look out.

After looking at it carefully for a while, Ding Chen still didn't find anything abnormal, so he turned his head to Uncle Potato and said, "I'll go out and have a look." ”

Uncle Potato shook his head, "Wait a minute." "It's always good to be careful," he said. ”

Ding Chen was about to complain when he heard this, when he suddenly found that the buzzing sound coming from outside the door disappeared, and was replaced by a dull clicking sound, as if something was moving.

He poked his head out again to check, and was shocked to see that the door was slowly lowering towards the ground.

Uncle Potato and Kiki also heard the movement coming from the hallway. Uncle Potato nervously asked, "What's wrong?" ”

"The door opened." Ding Chen said, his voice sounding a little weird, and he didn't know whether he was happy or sad. To be honest, even he didn't expect to be able to open this door.

Listening to Ding Chen's answer, Uncle Potato's face showed a look of relief, and Qiqi simply leaned over to Ding Chen's side and looked out the door. She has lived with Uncle Potato since she was a child, and she has no experience in dealing with the opposite sex, so she is not afraid to squeeze with Ding Chen.

Feeling the squeeze from Qiqi's body around him, Ding Chen subconsciously gave way to the side, so Qiqi saw the situation in the corridor and immediately screamed in surprise, obviously she still saw the door open down for the first time.

Ding Chen strode helplessly towards the potatoes and said, "You guys wait here, I'll go over and have a look first." ”

When the door sank below the ground, it revealed a staircase hidden behind the door, winding its way underground. Ding Chen stood by the door, looking at the stairs very happily, thinking to himself that fortunately, the designer here is not as brainy as in Hollywood movies, if he gets a cage here, will it go down or not?

Ding Chen had already guessed from the design of this building that there was another mystery under the ground, but at this time, looking at the traces left by the settlement of the gate under his feet, he was still secretly frightened. The thickness of the door is almost as thick as the façade of the building, and even exceeds the previous sealed doors. Luckily, he found a way to open the door, and if he really planned to use a hand-held cutter, he would probably have to cut until he was old, even if he had enough materials.

He stood at the top of the stairs and looked down, but saw no danger, so he beckoned back.

Seeing Ding Chen waving, Qiqi helped Uncle Potato and walked over, and then the three of them stood at the top of the stairs and looked down together.

Uncle Potato frowned and said, "There are vents down here." ”

Ding Chen let out an "um" sound. Now standing at the top of the staircase, you can feel a clear flow of air, and the direction is blowing from the bottom up. Unlike the natural wind outside the building, this one has a cold smell and the temperature is lower. But there is no discomfort in breathing.

"I'll go down first." Ding Chen picked up the battery light and said to the two people beside him.

Uncle Potato glanced at him, turned to Kiki and said, "You can go down with him, so you can have a helper." ”

Ding Chen frowned and said, "If there is really any danger, it is to accompany one and take another." ”

Uncle Potato thought for a moment, nodded and smiled, "That's right." In that case, why don't the three of us go down together. He said to Ding Chen: "Everyone enjoys the blessings, and the difficulties are shared together." If you are unfortunate enough to fall, you can also have a companion on the Huangquan Road. ”

Ding Chen was amused and angry, shook his head and scolded: "It's still falling, you've seen too much fantasy, right?" Besides, why do you like threesomes so much? ”

Uncle Potato didn't mean this, but when he heard Ding Chen's words, he immediately laughed. Kiki didn't know why, so she interjected and asked, "But we are indeed three people." ”

This time Uncle Potato smiled even more. Ding Chen looked at Qiqi helplessly and said, "I mean that if there is an accident, the three of us will have to die together." ”

Qiqi suddenly realized, she looked at Uncle Potato and Ding Chen, and said with a smile: "I am willing to die with you." ”

"Okay, don't tree flags." Ding Chen thought to himself, if there was really danger, it was estimated that neither he nor Qiqi would die, but Uncle Potato would be difficult to say. So he said, "Since we are not afraid of death, let's go down and have a look together!" ”

As the person with the best skills and the most experience, Ding Chen walked in the front without giving up, Qiqi helped Uncle Potato to follow him at a distance of about ten meters behind him, and the three of them walked slowly down the stairs.

The staircase down is long, and there is no turning in the middle, but it goes straight all the way down. The LED lights embedded in the walls of the stairs are not visible, but they emit a faint and cool light that illuminates the staircase. What's even more surprising is that the lights are clearly moving with the footsteps of the three people, and when they approach, the lights around them will turn on in turn, and as they move away, the lights will gradually go out.

Kiki didn't understand what that meant, she just felt curious. But Ding Chen and Uncle Potato obviously knew that to do this, at least prove that there were countless things similar to motion sensors installed in the long stairwell, and it was these sensors that detected their position at any time, and commanded the lights on the wall to turn on or off.

This also confirmed their previous suspicions - it is clear that there is always electricity underground, and there is an abundant supply of electricity.

Uncle Potato looked uneasily at the seemingly endless staircase in the darkness in front of him, and whispered to Ding Chen, "This is not normal. "The city should have been abandoned for at least 50 years," he said. ”

Ding Chen snorted, generally speaking, no large power supply device can continue to operate for fifty years without maintenance. Unless it is an escape pod like the one Ding Chen took when he landed, it only supplies power to the life-sustaining system in the cabin, and the power consumption is relatively small and stable, and it can be designed at any cost, so it can last for hundreds of years. Even so, it was actually the result of the cooperation of multiple power supply devices, if there was only one of them, Ding Chen would have woken up in the desert long ago.

In addition, even the most automated nuclear power plant cannot last more than 50 years on its own, and even if it is sufficiently charged, the slightest accident during operation can destroy the fragile load balance, and then explode without human intervention because it has been operating beyond its design capacity for a long time.

So a guess gradually rose in Ding Chen's heart, he slowly stretched out his right hand to Uncle Potato and made a somewhat complicated gesture, which meant to say, "Don't speak, there may be someone nearby." ”

Of course, it is impossible to hide people on this long staircase, but it is still easy to bury some monitoring devices, and Ding Chen believes that Uncle Potato can understand what he means.
