Du Di'an took off his coat, found a slightly drier ground beside him and put it on, and climbed into the garbage hole again with his shirtless. Fortunately, there is no steel and glass in this garbage. After all, steel is energy Recycling, no poor people would be so extravagant that they would abandon them, and as for glass products, poor people could not afford to use them either.

The pungent odor constantly eroded Du Di'an's brain, causing his stomach to tumble. From time to time, his palms would touch wet and soft objects. In the dark, it was unimaginable whether it was a lump of shit, or a rotting and puffed mouse corpse, here, even a sloppy poor, will feel that life is better than death.

Du Dian gritted his teeth tightly, and after climbing seven or eight meters, he finally touched a hard object, which was his freezer!

He felt along the gap in the edge of the case, quickly found a button, and pressed it down.

"Verifying your fingerprints..." A cold mechanical voice sounded from the darkness.

Soon, with a click, the freezer opened, and the force of the hatch opening pushed the garbage above it slightly, but more garbage fell into the freezer, almost filling the place where he once slept. Full.

Du Dian glanced at the hatch, where there was a two-finger-wide red number: 300.

This is the year.

It was this that let him know that he woke up three hundred years later.

The reason for three hundred years is because the three energy tubes in the freezer can only supply three hundred years of freezing, which is the limit.

Du Dian reached inside and quickly touched a raised button. With a click, an alloy built-in disk popped up in the cabin, with a palm-sized screen supported by several mechanical brackets.

"Scan the iris..."

The previous mechanical sound sounded from the cabin, and the iris recording light shot out from the palm-sized screen.

Du Dian immediately leaned up and aimed at his eyes.

"Verified..." The mechanical sound sounded again, and a three-dimensional virtual shadow popped up on the screen. There were two options, start, and exit.

Du Dian gritted his teeth slightly and chose "start".

When the disaster broke out, he was not the only one who was frozen, but also this super chip. It can be said that this is the essence of the civilization of the entire old era. It stores all the technologies of the old era and the social history of various countries, although these are all informational. It doesn't take up much memory when it comes to patterns, but thousands of years of social development and technological development in various countries around the world add up to at least tens of thousands of grams of storage.

Du Dian thought of his father's last words: "Remember, we must rebuild human civilization..."

Obviously, being able to use the freezer to escape the disaster, his father also considered the problem of human survival after the disaster, the outbreak of the global nuclear bomb, causing a devastating blow, the fault of civilization, and the things in this super chip, covering the All the wisdom of old times!

The basic principles of making gunpowder and firearms are naturally included.

"There is no "electricity" in this world. Fortunately, the remaining energy in the freezer can not be used for human body freezing, but it can at least maintain the basic operation of the freezer. It can be used to learn this for at least a few months. "Du Di's peace of mind estimates that the power consumption of this small screen is lower than that of a laptop, and it may not consume one kilowatt of electricity for 24 hours.

However, Du Dian didn't have so much time to stay here, and he didn't have time to come here often to watch, otherwise, it would arouse the suspicion of the Jules couple.

"You can only hurry up, let's learn how to make gunpowder and generators for the time being, and take a look at the tools of the steam age." Du Dian lay on the side of the freezer and began to study seriously.

The surroundings were full of stench, decay, and the unpleasant smell of feces and urine. He endured it. Gradually, he seemed to get used to it. Instead, he was attracted by the contents of the chip and devoted himself to it.

"Sulfur decomposition..."

"Watt's improved steam engine..."

In this small and dark garbage hole, Du Di'an studied attentively, time passed by unconsciously, Du Di'an was not completely absorbed, his concept of time was very strict, at about four o'clock in the afternoon, at dusk, he rubbed sour With swollen eyes, he withdrew from the teaching of the super chip. He didn't eat or drink for a whole day. He felt like a fire was burning in his stomach.

"I don't know when I can come next time. The outside of the freezer is covered with moss and rock ash from volcanic eruptions. It was thrown here as a strange rock. The rock layer cracked when the hatch was opened last time. If someone Sees, you will definitely notice that there is metal inside, and the super chip must be taken away." Du Di'an made a decision that it was too dangerous to keep the super chip here.

Previously, he did not bring the super chip when he was in the Meishan Orphanage. That was because the children of the orphanage were all sleeping together, and it was inevitable that people would notice. Although others did not know how to open it, they could not open it, but at least they recognized the memory chip. The player is metal and glass.

It's different now. There is no mobile power supply, and the player is equivalent to a dummy. He can only leave with the super chip. This small chip will not attract too much attention. Even if it attracts attention, no one will care. After all, the appearance of the chip is like a small sheet of metal, for people in residential areas, is not worth seeing at all.

Click, Du Dian opened the chip storage card slot on the back of the player and squeezed out the small chip the size of a fingernail inside. He sighed in his heart that thousands of years of human history are contained in this small chip if this The rulers of the world know what is in this chip, and they don't know how to look.

Carefully putting away the chip, Du Dian closed the freezer again, thinking secretly in his heart, I hope to see it again next time I come. He turned around with difficulty and crawled out of the garbage dump. The distance of just seven or eight meters was like a baptism from hell. When he climbed out of the exit, the air with a weaker smell outside breathed into his nostrils. It was so fresh.

He took a few deep breaths, looked left and right, and saw that no one was paying attention, and the coat was still on the ground, so he stopped staying immediately, picked up the coat, and quickly left the garbage dump.

Not far from the garbage dump, there is a low-lying land on which the radiation rain that fell a few days ago is accumulated. The water is quite clear, and Du Di'an is too lazy to care about the radiation, so he dropped his jacket and picked up the water to clean it. He raised his arms and chest. Anyway, there is a super chip. As long as a stable power supply is made early, he can find a way to reduce the radiation in the body.

He searched it before, and there was a record in the chip, but the time was limited.

Soon, the body was cleaned a little bit, and the sticky things were wiped off, especially the left hand, which was still stained with feces, making him nauseous.

"It's almost dead once." After washing, Du Di'an felt a new life, but he knew that there was still a strong stench in his hair and body. This can only be washed at home, otherwise, he will continue to use this stagnant water. , you will get sick after washing.
