After several failed attempts, Xiao Yu still had a total of fifteen years left. It would take at least two years to build a gravity bomb ten times the current power.

The power of the gravity bomb, after reaching a certain limit, will increase the difficulty exponentially with each point of rise. This is very similar to the hydrogen bomb. But Xiao Yu believes that this attempt is still worth it.

If this attempt can blow up the four-dimensional barrier, it is the best, even if it can't be blown up, Xiao Yu can still get another data, that is, the artificial gravity bomb, the upper limit of its gravitational force, is not the strength of the neutron star. If this limitation does exist, then Xiao Yu will regain a direction for research and struggle - since there is a limitation, there must be a reason. And as long as this reason is found, it means another technological breakthrough.

"During the period of making gravity bombs, let's continue to discuss and research, and we will list all the means that may have an effect on the four-dimensional barrier under our current level of science and technology, and conduct a feasibility assessment."

It doesn't take much computing power to make a gravity bomb, so Xiao Yu issued such an order to the Lukka people while making the gravity bomb.

"Master, I have a question." Lukka III, the most prominent scientist among the Lukkas, said, "My doubt is whether the Quadruple Hood is really so powerful that we can ignore all the attacks of civilizations of the same level except for the Gravity Bomb attack. This suspicion is based on a very simple contradiction, first of all, except for the flesh and blood of the white dwarf alien beast and the special way of existence of the master, I don't think we will be different from the rest of the fourth-level civilizations in the universe, then. The contradiction comes out, if we can find a way to destroy the four-dimensional maintenance cover, then the rest of the four-dimensional civilization naturally has the ability to destroy it, which proves that the performance of the four-dimensional maintenance cover is not strong. On the contrary, if the performance of the four maintenance covers is strong enough, then we have no possibility of breaking through it, which shows that Taihao is actually malicious to us. ”

"To sum up, my conclusion is that if Taihao is well-intentioned. Then the performance of the four maintenance covers must not be as strong as we imagined, if the performance of the four maintenance covers is strong enough, then Taihao is malicious. ”

Luca III's point of view caused the Lucca scientists present to think deeply, for a while. There was silence in the room.

This point of view also has a great inspiration for Xiao Yu. Xiao Yu also fell into thought.

A moment later. Among the Lucca scientists, the status is second only to Luca Three, and Luca IV Wells stood up and said, "I have some ideas that I can add to Lord Three's point of view. My conjecture is also very simple, I found. In fact, there is a possibility that these two contradictory speculations can be taken into account. That is, Taihao is not only well-intentioned, but also the performance of the four maintenance covers is strong enough. To achieve this result. Then we can only think from the direction of the master that is different from the rest of the fourth-level civilizations and find a way. For example, the master's strong computing power, such as the flesh and blood of the white dwarf alien beast. ”

"I agree with both of these statements." Another gray-haired old scientist stood up and said, "For now, it seems that this is really our only way to live. ”

"Actually, it's not just that." Inspired by Luca 3 and Luca 4, Xiao Yu also has his own opinion.

"There is also the possibility that it is possible to take into account the two contradictory points mentioned by the number three. That is, the means of breaking through the four maintenance covers, all fourth-level civilizations can master them, but this kind of jishu may have some kind of limitation, so it cannot be taken to the battlefield, so naturally there is no way to affect the performance of the four maintenance covers. Xiao Yu thought for a moment and said.

Luca III stood up: "I agree with the master. I think we should put all of these speculations together and prepare for both at the same time. The first preparation is to start thinking from the point where the master is different from the other level 4 civilizations, and the second preparation is to think about the technology that can be mastered by the level 4 civilization but cannot be used as a means of attack. ”

"Well said, Luca Three, you deserve to be my most capable assistant." Xiao Yu praised and concluded: "We still have fifteen years to go, if we still can't find a way after fifteen years, then we can only die together." So in the past 15 years, let's all work together to survive. ”

"The creation of super-large yield gravity bombs continues, but I don't think you should expect too much from them. The focus of our recent work has been on the two speculations that Luca III has said. During this time, everyone should brainstorm and strive to break through the four maintenance covers, regain freedom and the time of beauty and development. ”

After summarizing the meeting, Xiao Yu announced the adjournment of the meeting. So, a group of Lucca scientists dispersed and started their own research. At the same time, at the suggestion of the Chief Social Governor, Luca No. 2, Xiao Yu also specially conceived a questionnaire and distributed it to all Lucca people in Lucca society, trying to break through the current predicament with the help of the wisdom of all Lucca people. Of course, this questionnaire was deliberately disguised, and Xiao Yu hid what he really wanted to master behind a lot of word games, so Xiao Yu was not worried that there would be Lucca people to speculate on his true intentions.

The entire questionnaire was distributed among the New Home and the Paradise, and all Luccas, as long as they were self-conscious individuals, had to do it, even young Luccas who were only two years old and had just received their primary education.

What Xiao Yu attaches the most importance to is also the questionnaire of this part of the young Lucca. Although they don't have any scientific knowledge and don't have any complete logical thinking, it is for this reason that their thinking is also the most unfettered, and they can imagine some things that adults can't think of.

Xiao Yu hopes that he can give himself a little inspiration through the answers of these young Luccas.

The reason why he attaches so much importance to these young Lucas is because Xiao Yu faintly feels that he should have entered a misunderstanding. It is very likely that Taihao is well-intentioned, and the four maintenance covers are also strong enough, but he can destroy them. The way to unify these contradictory points may be hidden in the corners of one's own thinking, but no matter how hard you try, you can't find them.

Another two years have passed, and the radius of the four maintenance hoods has shrunk by more than 100 million kilometers, and correspondingly, the temperature increase rate in the four maintenance hoods has been further accelerated.

Just an hour ago, Xiao Yu had just finished the explosion of the second gravity bomb. Shiyan's result did not surprise Xiao Yu's expectations, and it was still a failure. There is no effect other than the bulge that once again attracts the four-dimensional barrier.

In this explosion, Xiao Yu also confirmed his previous guess, that is, the upper limit of gravity of the gravity bomb is indeed the level of neutron stars. Even if the power of the gravity bomb exploded this time was increased by ten times, the experimental results showed that this ten times only increased the killing range by ten times.

Xiao Yu speculated that this may be due to some slight difference between the gravitational force caused by the conversion of energy and the gravitational force caused by the mass of matter. After understanding this difference, Xiao Yu will once again deepen his understanding of microscopic shijie and fundamental physics. But now during this time, Xiao Yu really didn't have the heart to delve into this problem.

"It's only been thirteen years since death came...... It's been eight years, eight years, until I've used up all my fuel and had to dismantle the ship to get supplies. Xiao Yu thought silently.

During this time, Lukaxing put forward a lot of various suggestions, but most of them were directly shot by Xiao Yu. There were many suggestions that made Xiao Yu cry and laugh, and in the questionnaire, Xiao Yu even received answers such as: "Pray to the true God, the true God will bless us", "What is the four-dimensional barrier?" Is it OK to eat? ”

One of the most bizarre responses came from a kindergarten child, who wrote in the questionnaire, "Our science teacher is so vicious, I think it's the toughest monster in the universe." Just let it go to the four-dimensional barrier and reprimand loudly, 'If you don't get out of the way, I'll hit your palm!' The four-dimensional barrier will obediently disperse. ”

But among the countless strange answers, there are many quite reliable answers. One of them aroused Xiao Yu's great interest.

It was an answer from an unknown Lucca, who said, "I thought it would be possible to try the Large Particle Collider again, and perhaps make it shatter like a droplet of water in the first crusade by hitting the four-dimensional barrier directly with extremely high-speed particles." ”

In order to test this conjecture, Xiao Yu built the super-large yield gravity bomb and carried out the rest of the research, and at the same time, he also allocated a little computing power, and spent five months adjusting the orbit of the large particle collider to perform a collision Shiyan. But Shiyan's result still disappointed Xiao Yu.

The four-dimensional barrier was still good to stay there, not reacting, completely ignoring Xiao Yu's attack.

Looking at the tenacious existence that can't be broken or broken, Xiao Yu is very anxious and powerless.

"Am I really going to die around this red giant star and be its burial object? But how can this be, how can it be? ”

Countless attempts and countless failures made Xiao Yu's state of mind no longer able to remain calm. There have been many times when Xiao Yu thought of giving up, but always at the most critical moment, through strong reason, Xiao Yu suppressed this self-abandonment again. (To be continued......)
