I am the most prodigal in the world of online literature

In 3000, the super-tech world developed the latest technology, allowing you to travel freely in the universe.

At this time, the earthlings who have already colonized the moon, Mars, and Europa are already focusing on developing new colonies.As early as 2017, people on Earth have discovered a planet that is very similar to Earth and named it Sub-Earth.

The space aircraft carrier developed by scientists from [-] countries flew to sub-earth after five years.

The people on this ship have a major mission, which is to expand the territory and develop technology on the sub-earth.The sub-earth originally belonged to two hundred countries, but when the sky was high and the emperor was far away, the people who first landed on the sub-earth took the lead. In the end, the sub-earth people announced the establishment of six giant empires, It also means directly declaring independence.

After these people become independent, the earth has nothing to do.

This is the formation of the Sub-Earth Empire. After 1000 years of development, Earth and Mars and other planets will send 1000 billion troops, cost 8000 trillion, use [-] space carriers, [-] million landing aircraft, and [-] million tanks. Attack on Sub-Earth.

This battle has been fought for 100 years!

The two sides successively invested more than 20 billion troops, causing countless casualties.

According to incomplete statistics, just the damaged aircraft parts were scattered on the sub-earth, like snow falling for five full years.

In the end, this century-old war ended with a settlement between the two parties.

The sphere of influence in the solar system announced that it recognizes the legitimacy of sub-earth independence, and the two sides will have friendly exchanges.

But during this period, the two sides adhered to the strategy of "I am in you, and you are in me" and sent cosmic spies to each other.On the one hand, it is to steal useful information, and on the other hand, it is natural to steal important technology!

The information Lin Donglai got was that Cheng Yu's father had been targeted by cosmic spies from at least 300 countries.

This was something that no one expected, but Cheng Yu's father knew a strange person in his early years, and this strange person was a hero in the Jianghu in the words of ancient China.The two hit it off and formed a friendship.

It's a pity that this hero was regarded as a cosmic spy and imprisoned in a mysterious prison.

Even the rich and powerful in the empire are not qualified to visit such a prison, let alone visiting such a prison for no reason, even if there is no collusion with the people inside, I am afraid it is unclear.

Therefore, no one would dare to enter such a prison blatantly.

Let's talk about the sewers!
Sub-Earth is just like its name, even the development is in a sub-healthy state.

An empire built in just 1000 years is better than thousands of years of civilization.No matter how advanced the technology is, one problem cannot be avoided, that is, to build high-rise buildings on the soil, in a world of super technology, it will inevitably produce a very serious problem, that is, environmental pollution.

With the development of the ultra-technical world today, this kind of pollution is only controlled to the smallest extent, which does not mean that such pollution does not exist.

So where would this pollution be placed?
It was the sewer where Lin Donglai and Cheng Yu went!
The sewer is the safest area now. No one can live in this sewer for a long time. Even if Lin Donglai can wear protective clothing to shuttle in the sewer, it is impossible to live for a long time.

Because whether it is water or food, as long as it comes into contact with the sewer, it will produce severe toxicity.

Therefore, the empire, which itself does not want to carry out any policies in the sewers, has not invested advanced equipment in the sewers.Instead, the empire above the sewer was built to look magnificent.

No one would have thought that Lin Donglai would take Cheng Yu to walk slowly in the sewer for a few days.

Naturally, Lin Donglai couldn't do it. Cheng Yu's father had already thought of how to do it.He prepared the information for two sleeping bags. As long as Lin Donglai followed suit, he would be able to get two sleeping bags to live in the sewer space, and at the same time, he could eat and drink safely in such sleeping bags.

Even going to the toilet is not a problem.

In this way, Lin Donglai and Cheng Yu safely survived the crisis of being followed in the sewer, so that they could approach the repair factory they were going to in the safest way.

There is an even stranger person in the repair shop!
According to the data, his repair level is only a senior mechanic.

As long as the mechanics who repair cars and produce parts in the factory, everyone is at least a senior mechanic, so there is nothing unusual about it.

But what is strange about him is that he is always able to disappear like a ghost, and all the wages he earns are spent, but no one can find evidence of his consumption from the computer or any consumption place.

You know, in the super-tech world, it is impossible to spend money without leaving traces.

Some people also said, what if this person goes to a physical store for consumption?

Even if you pay in cash to buy a piece of gum in a physical store, the moment you buy the gum will be recorded.

And as long as it is an individual, as long as he needs to investigate this person and can give reasonable procedures, he can check such records.

That's the case!

This strange man was surprised that no one found out that he had any consumption records.

But every month, I really spend all my money!
For this reason, people from the Bureau of Investigation even took money to investigate him!
He came to a conclusion, that is, he had only one possibility, and that was to throw his money into the stinky ditch, otherwise, how could the money disappear for no reason!

His name is Xiao Qingsu!
After Lin Donglai and Cheng Yu went ashore, they immediately came to Xiao Qingsu's house.

Xiao Qingsu just came back from outside!

"You two come to my house, and my house key!" Xiao Qingsu said, "You must be the one looking for me!"

Lin Donglai said: "It's really helpless, but the situation is extremely urgent now!"

"Of course! If there is no urgent situation, it is impossible for the old man to ask you to come to me!" Xiao Qingsu said, "What do you want me to do for you?"

"We want to save someone while you are in prison!" Lin Donglai said.

"What prison, who is it?" Xiao Qingsu asked.

"The strictest prison, rescue a person who is least likely to be released!" Lin Donglai said, "This person is very important to us!"

"That's easy!" Xiao Qingsu said, "I just need someone to come forward and I can help you solve this matter!"

"What kind of person?" Lin Donglai asked.

"This person doesn't exist!" Xiao Qingsu said with a smile.

Cheng Yu asked in confusion, "Why does this person exist?"

"Because I fabricated this person out of thin air!" Xiao Qingsu said, "He has a normal life, and he has all the schooling experience from elementary school to university graduation. When and what diseases he has seen are recorded! All the photos and videos from the birth of the baby to the age of 34, he has an official position!"

"Impossible! How can such a person be fabricated out of thin air?" Cheng Yu said incomprehensibly.

"I think you guys already know about me, otherwise you wouldn't be able to come to me! So are you interested? Why do the money I earn disappear every time!" Xiao Qingsu said mysteriously, "Because I used a Do something!"
