In the end, it was of no use at all.

The hatch used to isolate the upper space opened in such an unexpected way, which really left people wondering what to say.

However, this also shows that Xu Lei's previous judgments were correct. Now that the upper space is officially unlocked for him, it also means that the influence he possesses has indeed met the requirements.

It can be said that Xu Lei was filled with great joy at this moment.

As the saying goes, there is no way out of mountains and rivers, and there is a bright future after another. However, no suitable exhibits were unlocked in the hall. As a result, the upper space that I had longed for was unlocked as expected, which somewhat restored some confidence.

But Xu Lei reacted the next second and knew that now was not the time to be stunned.

"By the way, let's first make sure what's inside."

After thinking secretly in his mind, he decisively stepped through the hatch and entered the upper space of the Science and Technology Museum for the first time.

Different from the imagined scene, judging from the things in front of you, it is almost the same as the situation in the hall. They are also neat and uniform booths. There are no other facilities except for them. The only difference is that these booths are all unlocked.

status, you can see a variety of items floating on it.

If the exhibits in the hall require influence to unlock new ones, then the upper space is directly open to Xu Lei.

And if you look around, you can't see the end at all.

It is enough to imagine how rich the exhibits collected here are.

At the same time, it further proves that the special nature of this science and technology museum seems to have transcended time and space and is in an unimaginable dimension.

After determining the true situation in the upper space, Xu Lei was used to seeing big scenes, and he couldn't help but take a breath at this moment.

"Hiss~"

Looking around at the massive exhibits, I felt from this moment that extraterrestrial civilization was not worth mentioning at all.

"This time it really gave me a big surprise. There are so many advanced technological exhibits. I don't believe that we can't handle the invasion of an extraterrestrial civilization." While muttering to himself, Xu Lei actually looked forward to extraterrestrial civilization.

arrival.

I believe it will definitely give them a surprise by then.

But before that, Xu Lei still had one thing to solve, and that was how to choose technological exhibits suitable for human civilization.

There is no doubt about it.

These exhibits in the museum can help human civilization move to a higher dimension.

But after all, museums are just collections. It is impossible to bring these things directly to the Earth and the planet. Humans need to produce them themselves based on the above technology.

This involves the issue of resources.

With Earth Star's current high-tech item manufacturing capabilities, it is very unrealistic to produce large quantities of advanced civilization items in a short period of time, and there are not so many resources and talents to complete it.

Therefore, it is the most appropriate way to select suitable exhibits for research.

It was a good idea, but Xu Lei was faced with so many different exhibits.

I can't really choose whether it's good or not.

Faced with this situation, Xu Lei had no choice but to force himself to calm down, carefully analyze the key to the problem and find a response strategy.

After the Earth Star mastered the controllable nuclear fusion technology and built a fusion power station and put it into use, it has officially entered the level of a first-level civilization. But now it can only control and use the resources of the Earth Star and the Moon. This is different from those of higher civilizations.

There's definitely no way to compare.

Such exhibits from high-level civilizations can basically be discarded.

After all, given the span of civilization levels between the two, it is estimated that even if the detailed technology is obtained, it will not be possible to build it.

In this case, secondary civilization is the main target.

According to Xu Lei's preliminary judgment, the signal from extraterrestrial civilization that was previously broadcast on the Earth Star was at most a second-level civilization level. Otherwise, Star Pupil might not be able to completely eliminate it.

According to this conclusion, even if the opponent is really preparing to invade the solar system, the force it sends in the early stage will definitely not be too much.

As long as human civilization can produce weapons and equipment that are comparable to the opponent's level, it will still have a high probability of victory if it waits for work.

At least it can buy more time for human civilization.

Even if the other party sends more forces to invade the solar system by then, I believe that human civilization will have completely grown up, and it is not certain who will invade whom by then.

After determining the direction, Xu Lei spent the next time searching among the many booths.

Fortunately, there are corresponding exhibits suspended above each booth. You can filter out many by appearance alone. This saves Xu Lei time in finding suitable exhibits. Fortunately, there is almost no time passing in the museum, so Xu Lei looks for

It doesn't matter how long it takes, otherwise it would be bad in the real world.

…

"Eh~"

I don't know how much time had passed, but Xu Lei, who was about to continue walking forward among a large number of booths, was suddenly attracted by a conical exhibit that looked like a rocket.

I couldn't help but let out a light sigh and stopped immediately.

Then he walked towards him decisively.

Coming closer, Xu Lei carefully observed the exhibit and immediately determined that it was an interstellar battleship.

We must know that what human civilization lacks most today is interstellar battleships that can form combat effectiveness in space. If we can master the manufacturing technology of battleships, we will undoubtedly be more confident.

"Finally, I have found a technological exhibit that is suitable for the current stage of human civilization. I hope its civilization level is not too high."

But Xu Lei also understood that whether the exhibit in front of him can be used depends on the level of civilization it belongs to and the difficulty of technological manufacturing. If it is too much higher than human civilization, it will not be usable.

Thinking of this, Xu Lei no longer hesitated, and immediately moved his gaze to the information screen next to the booth with an anxious mood.

But as the familiar template information came into view, Xu Lei's pupils suddenly dilated, and a strange look flashed across his face. Obviously, things were not as smooth as he had imagined.
Chapter completed!
