Dudian took off his coat, found a relatively dry spot on the ground nearby, and placed the coat there. Then, shirtless, he crawled into the garbage hole again. Fortunately, there was no steel or glass among these garbage items. After all, steel could be recycled, and no poor person would be so extravagant as to discard it. As for glass items, the poor couldn't afford them.
The pungent stench constantly assailed Dudian's brain, making his stomach churn. His palms would occasionally touch some wet and soft objects. In the darkness, it was impossible to imagine whether it was a lump of excrement or the decaying and puffed-up body of a rat. Here, even a slovenly poor person would feel that life was worse than death.
Dudian gritted his teeth tightly. After crawling for seven or eight meters, he finally touched a hard object, which was exactly his freezing chamber!
He groped along the gap at the edge of the outer shell and quickly found a button, then pressed it down.
"Verifying your fingerprint..." A cold mechanical voice sounded from the darkness.
Soon, with a click, the freezing chamber opened. The force of the chamber door flipping open pushed the garbage on top of it slightly upward, but more garbage fell into the freezing chamber, almost filling the place where he had once slept.
Dudian glanced at the chamber door, where there was a red number two fingers wide: 300.
This was the year.
It was precisely this that made him know that he had woken up three hundred years later.
The reason it was exactly three hundred years was also because the three energy tubes of the freezing chamber could only supply three hundred years of freezing, which was the limit.
Dudian reached inside and quickly touched a protruding button. With a click, an alloy built-in tray popped out from the chamber, and a screen the size of a palm was supported by several mechanical brackets inside.
"Scanning the iris..."
The previous mechanical voice sounded from inside the chamber, and an iris scanning light shot out from the palm-sized screen.
Dudian immediately leaned forward and aimed his eyes at it.
"Verification passed..." The mechanical voice sounded again, and a three-dimensional virtual image popped up on the screen, with two options: Start and Exit.
Dudian gritted his teeth slightly and chose "Start".
When the disaster broke out, he wasn't the only one who was frozen. There was also this super chip. It could be said that this was the essence of the civilization of the entire old era. It stored all the technologies of the old era, as well as the social histories of various countries. Although these were all documentary materials, with the accompanying pictures, they didn't take up much memory. However, when adding up the social and technological developments of all countries around the world over thousands of years, there was at least a storage capacity of tens of thousands of gigabytes.
Dudian thought of his father's last words: "Remember, you must rebuild human civilization..."
Obviously, since his father could think of using the freezing chamber to escape the disaster, he also considered the survival of humanity after the disaster. The explosion of global nuclear bombs caused a devastating blow, leading to a break in civilization. And the things in this super chip covered all the crystallization of wisdom in the old era!
The basic principles of making gunpowder and firearms were naturally included as well.
"There's no 'electricity' in this world yet. Fortunately, the remaining energy in the freezing chamber, although it can't be used for human freezing, can at least maintain the basic operation of the freezing chamber. Using it to study this, it should last for at least a few months," Dudian estimated in his heart. The power consumption of this small screen in front of him was lower than that of a laptop. It might not even consume one kilowatt-hour of electricity in twenty-four hours.
However, Dudian didn't have so much time to stay here, nor did he have the time to come here often to study, otherwise, it would arouse the suspicion of Mr. and Mrs. Jula.
"I can only hurry up. For now, I'll first learn how to make gunpowder and a generator, and by the way, take a look at the tools of the Steam Age," Dudian lay beside the freezing chamber and began to study seriously.
Surrounded by the stench of decay and the unpleasant smell of a mixture of excrement and urine, he endured it. Gradually, he seemed to get used to it. Instead, his mind was attracted by the content in the chip, and he devoted himself to it wholeheartedly.
"Sulfur decomposition..."
"James Watt's improvement of the steam engine..."
In this narrow and dark garbage hole, Dudian studied attentively. Time passed unknowingly. Dudian wasn't completely engrossed. He had a very strict sense of time. Around four o'clock in the afternoon, at dusk, he rubbed his sore eyes and exited the teaching of the super chip. Having not eaten or drunk anything for a whole day, he felt as if there was a fire burning in his stomach.
"I don't know when I can come next time. The outside of the freezing chamber is covered with moss that has grown over time and the ash from volcanic eruptions. It was regarded as a strange rock and discarded here. When the rock layer cracked when the chamber door was opened last time, if someone saw it, they would surely notice that it was made of metal inside. I must take the super chip away," Dudian made a decision. It was too dangerous to leave the super chip here any longer.
Previously, when he was in Meishan Orphanage, he didn't take the super chip with him because the children in the orphanage all slept together in a large bed, and it was inevitable that someone would notice it. Although others didn't know how to open it and couldn't open it either, they could at least recognize that the player storing the chip was made of metal and glass.
Now it was different. Without a mobile power source, the player was useless. He could only take the super chip away. This small chip wouldn't attract too much attention. Even if it did attract attention, no one would care. After all, the chip looked like a small metal piece on the outside, and for the people in the residential area, it wasn't even worth a second look.
Click. Dudian opened the chip storage slot at the back of the player and pinched out the small chip the size of a fingernail. He felt a bit emotional in his heart. Thousands of years of human history were all contained in this small chip. If the rulers of this world knew what was in this chip, he wondered what kind of expression they would have.
He carefully put away the chip and closed the freezing chamber again. He thought to himself, hoping that he could still see it when he came next time. He turned around with difficulty and crawled out of the garbage pile. The distance of just seven or eight meters felt like going through a baptism in hell. When he crawled out of the exit, the air outside, which had a slightly weaker stench, felt so fresh when it entered his nostrils.
He took a few deep breaths, looked around, and seeing that no one was paying attention and his coat on the ground was still there, he didn't linger any longer. He picked up his coat and quickly left the garbage dump.
Not far from the garbage dump, there was a low-lying area where the radiation rain that had fallen a few days ago had accumulated. The accumulated water was rather clear after precipitation. Dudian didn't bother to care about the radiation or not. He threw down his coat, scooped up the water, and washed his arms and chest. Anyway, with the super chip, as long as he made a stable power source early, he could find a way to reduce the radiation in his body.
Previously, he had searched in the chip and found that there was a record of it. It was just that he didn't have much time, so he didn't read it carefully. After all, it was useless to read it now.
Soon, his body was cleaned a bit. He wiped off all the sticky things on his body. Especially on his left hand, there was even excrement stuck to it, making him feel nauseous.
"It's like I've died once," Dudian felt a sense of rebirth after washing. However, he knew that his hair and body still emitted a strong stench. He could only go home to wash it. Otherwise, if he continued to use this accumulated water, he would get sick after washing.
