This world has satellites, shelter ground base stations, free communication benefits for all, and unlimited computing resources...... But there is no chat group, no circle of friends, no Weibo, no advertising...... In the shelter passage, you can't yell at everyone.

"According to the Law on the Prevention and Control of Information Pollution, the release of information to more than two unspecified persons requires a hierarchical authorization from the Security Council. Different levels of permissions, when publishing information, there are restrictions on the number of objects, regions, contents, etc. ”

Du Bin gave a lecture on law popularization to Zheng Yi.

Zheng Yi always felt that Du Bin was a legal bully disguised as an engineering student. This guy knows the law before the cataclysm very well, so what engineering student would read the history of the legal system?

"The Information Pollution Prevention and Control Law is a second-level code in the shelter, and our daily lives are affected by it." Du Bin said: "Of course, it also has legal effect on the surface. ”

"There are so many robbers and murderers on the surface, who cares about people building groups and chatting?" Zheng Yi was speechless.

"It's not about killing people and robbing people, it's just that you can't control it." Du Bin said: "The shelter has limited resources and fragile ecology, so we will not interfere in anything that does not endanger the survival of human beings. It's just that it just has the ability to prevent information pollution: it's easy to use AI algorithms to prohibit crowding and control servers. ”

"In the event of a cataclysm, the problem caused by information pollution is very serious." Du Bin said: "The spiritual shock wave brought by the group unconscious is very terrifying. Millions of people were frenzied by false information, which is why the ancients urgently passed the Information Pollution Prevention and Control Law in the early days of the cataclysm. ”

"Okay, okay, we can do it by word of mouth." Zheng Yi said.

Du Bin said: "If you want to advertise, you can apply to the Western Regions Administrative Center, and they will apply for permission after verification and entrust the local publication." ”

Zheng Yi shook his head and didn't dwell on this matter. He's not a network dependent. How can the anatomy of a group of water be interesting? He said to Du Bin: "We're going back tomorrow, what are you doing in the past two days?" ”

Du Bin said: "A gift for you." ”

"Yo?" Zheng Yi's eyes lit up: "What gift?" ”

"You'll find out tomorrow."

Zheng Yi didn't expect Du Bin's cold appearance to give him a gift, and he felt like a subversive personality. He didn't ask, anyway, he would know tomorrow, and now he had to go out to the store.

Zheng Yi heard the palace guards discussing a world-renowned treasure today, and it would be a pity not to go and see it.

And he has to take Du Bin with him.

……

……

Locomotive Shop No. 883 in Hangcheng is displaying the Vault's latest single-person locomotive. The locomotive is powered by a miniature fission reactor and can reach a top speed of 800 kilometers per hour.

When Zheng Yi heard that he could run at 800 kilometers per hour, he decided to meet it.

This speed is more than half Mach, and you can fly properly with your wings.

Du Bin has a special affection for all machinery, and almost never forgets all kinds of data. In front of the empty display table, Du Bin repeated to Zheng Yi the data he remembered:

"Acceleration to 100 km/h in 1.3 seconds. The body weighs 700 kg ......"

Zheng Yi really wanted to pay for it immediately.

It's good to be poor, so I don't spend impulsively.

"How long can it run?" Zheng Yi asked.

Du Bin held up a finger.

"100,000 kilometers?" Zheng Yi plucked up the courage to guess.

Du Bin shook his head.

"1 million?"

Du Bin still shook his head.

"10 million?!"

"Keep running." Du Bin said: "The energy provided by the reactor is enough for it to run for a lifetime. What's more, the faster this car goes, the shorter its lifespan. Do you know how much damage a rock can do to its frame if you run over it at 800 km/h? ”

Zheng Yi shook his head: "If you say that...... No wonder no one buys it. ”

Du Bin said bluntly: "The main reason why no one buys it is expensive." ”

Zheng Yi felt a little pain in his heart, and hurriedly [understood] it.

Fortunately, it's just that the content is too real and causes discomfort.

"The price of the car itself is high, and the cost of using it is also very expensive." Du Bin said: "When it runs, it needs to inject refrigeration gas to cool the tires, and at the same time, the cooling system of the bearings needs to be replaced frequently, which is equivalent to an ordinary motorcycle." So when you turn on the engine, this thing is burning money. ”

Zheng Yi sighed: "Then why did the shelter build it?" ”

Du Bin said: "If you are asked to work for the shelter, are you willing?" Zheng Yi's face stiffened, and he almost blurted out "why".

Du Bin continued: "But there must be people who are willing to work for this car. ”

Zheng Yi was speechless.

Du Bin asked again: "Do you want to buy a car?" Inconvenient to use Mr. Banzhang's car? ”

"It's not inconvenient," Zheng Yi shook his head, "First of all, speed and passion are a man's waste, you don't understand." Secondly, the old class of the car...... Don't you think the comfort level is too low? I'm going to give him a different engine, uh, in the form of a stake, you see. ”

"You can't afford to change it, unless Mr. Executive has another incurable disease." Du Bin is telling the truth. Not only must he be seriously ill, but he must also be a person who cherishes his life, and in the end, this person has a very high status and can open his mouth widely.

Zheng Yi looked at the locomotive and shook his head: "If only the matching engine was added to ...... at that time"

"That's not fair." Du Bin said.

Zheng Yi knew that Du Bin would not lie to him. Although I don't know how this kid met the executive, no matter what their relationship is, the two of them are very fair. This is probably the general character that the shelter has cultivated.

The two chatted while looking at the car. For those who like it, this car is the jewel in the crown of industry, from the curves of the frame to the stitching of the seat cushions, every detail is worth seeing.

Zheng Yi has never seen "flowing metal". This liquid memory metal was a science fiction stuff back home, but in front of you it, a real product – a tyre, that can withstand the damage of huge pressures, keep it running wild on all kinds of ground, have low wear and always maintain grip.

"Hah, this car is still there." A loud voice rang out behind the two of them.

Zheng Yi immediately thought of the "Information Pollution Prevention and Control Law", which is already illegal to publish information to multiple people who are not sure!

The clerk walked quickly, holding a black locket full of black technology.

Probably an electric shock rod or something - Zheng Yi guessed.

"Do you like it? This is the most high-tech representation of the Vault, and there is no production line on the surface, and the number of surviving is extremely low. The clerk was holding a small black box.

Zheng Yi took a closer look at the small black box, which turned out to be a POS machine.

Du Bin gently pulled Zheng Yi and motioned to get out of the C position.

This position is a bit of a camera-grabbing position.

Zheng Yi glanced back, it was a giant more than three meters tall.

In terms of stature, it is indeed worthy of this car.

In terms of strength...... Zheng Yi saw a red spirit body that was stronger than the leader of the Black Hand Legion, and pulled out a trace of ochre red streamer as he moved.

This is a Sequence 5 formidable warrior.
