Road to science and technology

Something like this.

It was given directly without any test.

After a long time, Xiao Yu brought his thoughts back to reality. After he shouted a few words about the lens detector and received no response, he realized that it seemed that the lens detector had really left.

At the same time, he also realized that he still had many questions that he had not yet had time to ask.

For example, Xiao Yu wants to know the details of the war between the semi-fourth-dimensional Taihao and the sweeper civilization. He also wants to know about the semi-fourth-dimensional Taihao and what information is hidden in the four-dimensional protective shield. He wants to know why the Neutron Battle Star is so powerful, and even more. Find out if this inscrutable detector can resurrect the Earth girl.

Xiao Yu believed that the lens detector and even the creator behind it were well-intentioned, at least so far, so he thought that as long as he opened his mouth, the other party would express something, but he left without paying attention.

"Forget it, I can't rely on others for everything. This lens detector has given me enough help."

Xiao Yuxin said something, then turned his gaze to the group of two-way foils outside the porthole again, and said excitedly: "Then let me take a good look at these things!"

Two-way foil was something he had never come into contact with before.

It stands to reason that he should send a detector to observe it first, but this thing is not a strange thing discovered by accident, but a gift from someone else, and it comes with an instruction manual.

So Xiao Yu immediately retrieved the data stored in his storage device by the lens intelligent consciousness.

It feels so cool to have instructions directly.

Then, Xiao Yu began to read carefully.

The instructions are of course very detailed, and there are a lot of rules and regulations, but the focus is without exception on how to use, how to trigger, and the expected effects after triggering, etc.

The format is not much different from normal drug instructions.

Xiao Yu discovered that this was indeed just an instruction manual, and there was no relevant manufacturing technology in it.

In fact, Xiao Yu also knew that even if he had the manufacturing technology, he would not be able to make it himself.

Because Xiao Yu knows that space technology needs to be initially involved in the sixth-level civilization, and space technology generally refers to the space of the three-dimensional universe, that is, the understanding and application of the large universe, and dimensional technology is the deeper level of space technology.

So Xiao Yu didn't think too much. After knowing how the two-way foil was triggered, he realized a problem.

That is, this thing seems to be dangerous, not only to the enemy, but also to the user himself.

Because the two-way foil must be unpacked under a specific force field, and after being unpacked, it means that the two-way foil has entered the triggering state.

According to the instructions, the triggering state of this batch of two-way foils can be long or short. The triggering state of the pile on the left side of the string window is longer, requiring twenty days, while the stack on the right side takes four days, and the pile in the middle needs At the shortest, it only takes one day.

Xiao Yu understands that these are the times after the package is unpacked until the two-way foil actually explodes. In layman's terms, it is the fuse.

But why are they divided into three different batches?

Xiao Yu didn't understand it, but with his intelligence, he probably understood it after thinking for a while.

Sure enough, he didn't need to summon the Lucca scientists to discuss it. He just recalled what the lens detector said before, and combined with the instructions, he roughly understood the reason.

That is the time reserved for yourself to escape.

Xiao Yu had long known from Lucca scientists that the upper limit of the speed of a fourth-level civilization could basically not exceed 10 times the speed of light, and he knew from the lens detector that once the two-way foil was triggered, it would directly cover a 0.6 light-year radius. The space is pulled to two dimensions. This range is reached instantly by the explosion, and then it spreads to a range of 1 light-year.

Therefore, after unpacking the force field and throwing the two-way foil, Xiao Yu must run away at least 0.3 light-years before the two-way foil actually explodes, so as not to be hit by the two-way foil.

So after simple calculations, Xiao Yu came up with the minimum conditions for using two-way foil.

That is, the speed of your fleet must reach at least 5.5 times the speed of light in order to run a safe distance of 0.3 light years before the two-way foil with the longest lead erupts.

If you want to be more stable, consider it 6 times the speed of light.

If you run at six times the speed of light for a little over 18 days, you will be able to run out of this range.

"Well, at the level four civilization stage, I can only use the leftmost pile. According to this setting, the other two piles should also correspond to different speeds."

Xiao Yu secretly said: "This must be the case. The maximum speed of a fourth-level civilization is ten times the speed of light. It will take about eleven days to travel 0.3 light years. If you want to use the batch of two-way foils on the right, you have to reach at least thirty times. The speed of light is considered absolutely safe, and as for the pile in the middle, it needs to be at least one hundred and ten times the speed of light to be considered safe."

"Well, when I, the semi-fourth-dimensional Taihao, was fighting against the sweeper civilization, I asked for help from the Guardian Alliance. The Guardian Alliance once reported on the radio that if you have the ability to sail at a speed of more than a hundred times the speed of light, you can go to the battlefield on your own. , I estimate that to achieve this speed, at least a level 6 civilization can achieve it.

In this way, the one with the longest lead of these three piles of two-way foil should be specially used by the fourth-level civilization, the four-day batch should be used by the fifth-level civilization, and the shortest one is undoubtedly the sixth-level civilization. "

This shows that this thing can even deal with a sixth-level civilization. This is too strong!

Thinking of this, Xiao Yu felt excited in his heart. If he still had a heart, it would be beating violently.

Xiao Yu originally thought that giving himself a gift of a fourth-level civilization could only deal with a fourth-level civilization, but he didn't expect it to be so powerful.

In fact, Xiao Yu also thought about whether he could send a battleship to carry the two-way foil out and unpack the force field alone, but the instructions told him that no, or that it couldn't be done with the technology of his current fourth-level civilization.

Because the energy encapsulated in the two-way foil is so huge that it can instantly two-dimensionalize a 0.6 light-year space, and it also spreads outward to a range of one light-year, so this energy is so huge that it can encapsulate Its force field must also be very solid.

Based on the instructions, Xiao Yu calculated that in order to unseal a piece of two-way foil, the decay power furnaces of at least ten provincial-level spacecraft would need to be fully output at the same time.

You know, the provincial spaceship is the largest spacecraft that Xiao Yu, a fourth-level civilization, can build.

The batch of bidirectional foils with shorter triggering times require greater energy supply to quickly decapsulate.

This is actually determined by the rules of this universe, because this universe is different from the three-body universe. It is a three-dimensional stable universe. The two-dimensionalization cannot be carried out infinitely. It is extremely difficult to two-dimensionalize the three-dimensional space. of.

So these two-way foils are like bomb grenades to Xiao Yu, rather than continuous output of guns. Of course, it is not an ordinary bomb, but something like a strategic weapon.

Understanding this, Xiao Yu immediately counted the number of these three piles of two-way foil and found that he could only use 6,000 pieces at present, while the other two piles contained 10,000 pieces and 20,000 pieces respectively.

"Well, six thousand pieces are enough. The rest will be saved first, and they will be used when you have the strength. Then, the next step is to make a container to store the two-way foil."

Xiao Yu thought about it secretly, and then immediately summoned Luca scientists for a meeting.

The reason for the meeting is that the storage container is not easy to make. Xiao Yu has read the instructions and knows that the two-way foil must be touched with a special force field, and ordinary substances cannot touch it at all.

Moreover, it stands to reason that the energy contained in the two-way foil is so huge that it should show a very strong gravitational effect, but Xiao Yu did not find even a trace of gravitational effect on the two-way foil.

Based on this phenomenon, Xiao Yu felt that he also needed to study it. Although he knew that he would not be able to study anything, he could always collect some data.

Because of this mentality, it was inevitable to bring Luka Science to the meeting.

On the other hand, due to the need to obtain these two-way foils, Xiao Yu had to continue to stay here, and this stay lasted for more than 20 years.

After continuing to struggle for more than twenty years, Xiao Yu finally created a storage container and embarked on his journey.

Somehow, the twenty years that were originally faster than the original work to escape the four-dimensional barrier were consumed again, so that Xiao Yu reached the material-rich star system and closed it secretly.

And all this was seen by the defender, but he still did nothing and just watched.

Not only that, he also knew everything about the lens detector and Xiao Yu, but he still did not take any action, nor did he stop the detector from leaving.

In fact, the defenders did not discover the existence of the lens detector at first, but it was discovered the moment the lens detector came into contact with Xiao Yu.

However, the defender still did not stop him, and still watched quietly as usual, like an eternal god.

It's as if as long as he doesn't interfere with Xiao Yu, no matter what the process is, the completion plan will definitely succeed.
