The Three-Body Problem: The Most Competent Wallfacer of All Time

Chapter 250 The Civilization That Passed By

Jiang Yu continued to ask: "Since time travel cannot change history, isn't what you are doing now changing history?"

JK15 replied in Jiang Yu's mind: "Most of the answers to this question cannot be explained, but some of them can be answered. Answers that can be answered require 6000 million fraud points. Will you pay?"

Jiang Yu had a toothache for a while, he couldn't spend all his remaining fraud points here!He has more important things to do!

Jiang Yu pondered for a long time before saying: "Jiang Shiliu didn't communicate with me directly, but communicated with me through you.

"I guess you should be a product of cheating who avoided some rules, or a product of using some loopholes to communicate with me?

"As long as you and I can follow the most important laws, there will be no disastrous consequences, and you can remind me of some key issues, right?"

JK15's voice showed no emotional change: "The answer to your question requires 3000 million fraud points, do you want to pay?"

Jiang Yu said: "No payment."

Through the changes in the fraudulent value of these two questions, Jiang Yu estimated that his guess was correct, maybe not all right, or there may be more important information that he did not grasp.

But this information is not the information he urgently needs now, so he won't waste the money.

Jiang Yu also understood. No wonder the "Wallfacer Store" has become very tasteless for a long time. It turns out that it needs to follow very strict laws.

Without completing the trigger conditions, it is impossible to show a further step.

Even if it has a further effect, it will be an auxiliary effect. After all, it cannot directly answer many questions.

At most, it is to provide some information, and Jiang Yu is still required to make plans and implement the problems encountered.

But this is not bad. Humans in the Trisolaran universe are very ignorant, because they dare not communicate, and most intelligent creatures in the universe are as ignorant as frogs in a well.

With the information of JK15, human beings will no longer ruin themselves because of extreme ignorance.

Although Jiang Yu had a lot of questions, he was not in a hurry to ask them. Good steel should be used on the blade, and his remaining fraud points should be used for other purposes.

As for the information about Jiang Shiliu's future, Jiang Yu didn't intend to mention it to the second person, not even Jiang Shiliu.

First of all, there is insufficient evidence to win the trust of others, and secondly, if it causes Jiang Shiliu's ideological dilemma, then the loss outweighs the gain.

It is good to understand this question in your own mind.

Now Jiang Yu is very interested in the third product. After exiting the JK15 page, he quickly used 1000 million fraud points to unlock the product.

To Jiang Yu's surprise, the product can be used immediately after unlocking.

The name of the item is: Two-Way Foil Strike Countdown!
后面是倒计时：185年6月9日6：51：32
The last number is seconds. When Jiang Yu was staring at the countdown in a daze, 32 became 31, and then 30.

This is the first time that Jiang Yu has such an intuitive feeling about the end of human beings. Before, he always felt that there will be some deterrence era, broadcasting era, etc. in the future. It seems that there is still some time.

But these times add up to less than two centuries!
This made Jiang Yu pay more attention to the No. [-] plan that he will implement. Even if his plan fails in the future, at least human beings still have the No. [-] plan.

When Jiang Yu was in a heavy mood, No. [-] sent him the information he asked for just now.

Jiang Yu opened the information and looked at it. Humans know too little about the planetary systems around the solar system.

It's not that people don't want to pay attention to this aspect, but that the distance from the earth is too far, and the specific conditions in these planetary systems can't be seen clearly with optical telescopes.

For example, human beings' understanding of Barnard's star is limited to knowing that it is a red dwarf star.

Now that the information on the "Wallfacer Store" was determined to be so important, Jiang Yu made a decisive decision and purchased the profile of Luhman's 16 stars.

This time, the "Wallfacer Store" did not reflect its profiteering nature. The general situation of the third planetary system still needs 2000 million fraud points.

Jiang Yu purchased information on two planetary systems, Wolf 359 and Lalande 21185, in one go.

Immediately afterwards, the profile of Sirius required 4000 million fraud points. Jiang Yu hesitated a little, and spent the last 4000 million fraud points.

Now that he has detailed information on the five planetary systems in his hand, Jiang Yu began to make a summary after reading it carefully.

It is not realistic to use the "store" to buy all the information of the surrounding planetary systems, and it is too late to get so many fraudulent values.

So Jiang Yu thought of using the information obtained from these five planetary systems to summarize the general situation of other planetary systems.

This kind of summary can be described as "unprecedented", because human beings do not know the detailed information of other galaxies except the Trisolaran galaxy.

The situation of the Trisolaran galaxy is more extreme and unrepresentative, so until now, human beings don't know much about the situation of other galaxies.

Although I dare not say that the planetary systems within 30 light-years of the solar system can meet the general situation based on the information of these five galaxies, it should not be too different.

After summarizing, Jiang Yu found that no planetary system lacks fuel for nuclear engines and metal deposits required by industry.

Even for the rare double brown dwarf planetary system Luhman16, the two main stars themselves are brown dwarfs that are larger than Jupiter but have not yet reached the star level.

These two main stars are natural nuclear engine fuels. Compared with Jupiter, the gravitational force of the two main stars is much greater than that of Jupiter, and because there are two main stars, the gravitational field is more chaotic than that of Jupiter alone.

A single-handed starship might struggle to get fuel from brown dwarfs in such an environment.

But there is also an terrestrial planet orbiting one of the brown dwarfs, and two terrestrial planets orbiting the two brown dwarfs.

The binary star system is also relatively stable, and there will be no chaos like the three-body galaxy.

There is a lot of ice on these three terrestrial planets and their surroundings. Collect these ices, melt them into water, and then extract hydrogen from the water, and further extract deuterium, and then there will be fuel.

Although the steps are more complicated and the process of finding ice is more troublesome, the fuel for nuclear engines can be obtained from these ices.

Theoretically speaking, with the current level of human technology, new colonies can be built in any planetary system, or use these planetary systems as a springboard for the next step.

In addition, two of these five galaxies once had civilizations, and the remaining three did not have the conditions for the formation of civilizations, at most there were some multicellular organisms.

According to this ratio, the probability of civilization occurring in the galaxy is quite high.

And it is almost "one foot in the sky and one foot in the ground". Planetary systems that were once more suitable for biological evolution will basically evolve intelligent creatures.

If there is no galaxy with such an environment, civilization may never emerge.

Time passed by the civilizations of the various galaxies. Regardless of whether the two civilizations perished or flew away, the surrounding solar system today, except for the Trisolaran galaxy, is either a ruin or a piece of virgin land.

Jiang Yu compared the information he bought from the "store" with the information sent by No. [-].

Today, astronomers' understanding of the surrounding planetary systems is basically limited to the stellar conditions of the planetary systems, and information on one or two planets can only be obtained by accident.

As for the situation of the stars, apart from a slight deviation in the distance, the information in the hands of astronomers is quite reliable, at least it can be used as the navigation target of the spacecraft.

　Thanks to [Luo Ze Long Er] for the 100-point reward.
