On Planet 8, in a house in Zone C of City 156, a boy with a mediocre appearance of a student returned home. A mother's voice came from inside the house: "Jianqi, you're back." ”

The teenager agreed, and his eyes were drawn to something nearby. He walked over, picked it up, and muttered to himself, "War strategy games...... Gratis...... Marshal ......"

He took the device and walked to his room, and entered the game world. In the game, he owns the first extremely rudimentary village-level spaceship, and then steps into the vast universe. He carefully observed the world, observing the various ships that were constantly shuttling back and forth in space. Most of these ships were the same village-level ships he controlled, and occasionally passing by a township-level spaceship would cause a burst of exclamations. And these township-level spaceships are also like majestic big men, triumphant and proud.

"Hey, it's just a village-level spaceship, and it dares to get in my way, so get out of the way! Lao Tzu is going to upgrade the battleship, delaying my time, Lao Tzu will kill you! When Yang Jianqi was getting acquainted with this world, a township-level spaceship suddenly stopped in front of him and said impatiently.

This township-class spaceship has a very loud name, Aotian. And the name of the spaceship controlled by Yang Jianqi is very ordinary, it is his name, Jianqi.

At this time, Yang Jianqi's heart suddenly moved: "According to the above statement in the novice guide, it seems that I can attack it here, and if I comprehensively analyze the performance of village-level and township-level spaceships...... I'm no match for him, but I still have a chance. He's careless now, the defense system is not doing a good job, and if I can do a fatal blow to his power system, I have every hope of winning......"

Thereupon. The Jianqi of the village-level spaceship began to slowly approach the Aotian of the township-level spaceship......

Just when countless people of the Shenzhou civilization fell into the obsession with this war game and couldn't extricate themselves, Xiao Yu was still working with countless scientists to carry out the scientific and technological analysis and integration of the Radiance spacecraft.

Hundreds of years have passed since the beginning, and a group of scientists have not disappointed Xiao Yu. With Xiao Yu's overall planning and strong assistance, the scientific and technological analysis work has come to an end. Xiao Yu has integrated most of the Guardian Civilization technology into his own technology system. Xiao Yu's technology has made a large-scale leap forward.

"With my current scientific and technological strength, give me enough time to prepare for the construction of a battleship, I'm afraid that without the help of MSI corpses, I can also destroy the Guardian civilization......" Xiao Yu thought secretly.

Now, Xiao Yu is presiding over a wrap-up meeting. All the important scientists were present and were reporting the progress of their current work to Xiao Yu and the rest of the scientists.

"It's a pity. We still haven't analyzed the four-dimensional jumping technology, all we can do is to use this ready-made four-dimensional jumping equipment and install it on the flagship of our civilization, so that the flagship has the ability to jump in four dimensions. A scientist said.

"Four-dimensional jumping is originally a technology that transcends the scope of sixth-level civilization. It's enough to be happy with this result. When our civilization truly becomes a seventh-level civilization, we will be able to completely overcome the scientific and technological problems in this area. There's no rush yet. Xiao Yu said.

Xiao Yu also participated in the scientific and technological analysis of four-dimensional jumping. Naturally, we know how difficult it is to be. This result appears. It was originally expected by Xiao Yu.

"The space fold technology has been analyzed, the holographic defense technology has been mastered by us, and there has been a little breakthrough in the black lightning technology, and it is expected to be analyzed in the future, but this will not affect the progress of our warship manufacturing. According to the current information, it is impossible for Black Lightning to be equipped on the ship. It can only be activated with the help of a large area of space and many stars. The analysis of material science and technology has been completed, and the analysis of the protective cover system has been completed. ”

"It's good, we're going unexpectedly well." Xiao Yu nodded and said, "Here." I would like to solemnly commend the following scientists, Xu Junpo, Luca No. 3, No. 4, and No. 5. It is the existence of these four scientists that we have been able to achieve so much in such a short period of time. In the coming time, due to the existence of the seventh-level barrier, it is unlikely that we will be able to make any more breakthrough technological progress, so you can take a good rest. Before defeating the Sweeper civilization, I don't plan to attack the seventh-level civilization. ”

Yes, by now, Xiao Yu really knew what the seventh-level barrier was, and he also knew why it would be so difficult for a sixth-level civilization to be promoted to a seventh-level civilization. A seventh-level barrier completely separates the seventh-level civilization from the civilization below.

Level 7 barriers come from basic science. Basic science is the foundation of all scientific and technological progress, and without the progress of basic science, there can be no major breakthrough in applied science. And the current situation is that in a short period of time, there will be no major breakthroughs in basic science.

In the research of high-energy physics, fundamental force research, space nature, etc., Xiao Yu found that there will be some uncertainty in his experimental results, and this uncertainty has no law. For example, if the result of this test is one, the result of the second test may be two, and the third test may be nine. It is this uncertainty that makes Xiao Yu feel lost. You must know that physical testing is a very accurate thing, and an error of a few hundred decimal places can cause very serious consequences, let alone such a large error.

Reproducibility is one of the basic requirements of physical experiments, that is, if someone claims to have extracted gold from iron in a test, then your experiment must be repeatable, not only can you refine gold by performing this experiment, but other people should also be able to extract gold according to the same steps, and your experimental data will be convincing. But the current situation is different, when Xiao Yu came into contact with some of the scientific experiments at the pinnacle of the sixth-level civilization, this reproducibility was broken.

The results of the test will be one, one will be two, and one will be nine, and each result will be non-reproducible. Xiao Yu first did a lot of work to make sure that the test machine was free of malfunctions, but this uncertainty continued to appear. As a result, there was no way to carry out the research at all, because Xiao Yu did not know which result was true and which was false.

Xiao Yu knew that this was the seventh-level barrier. Either because of some unknown principle in the universe, or because of an unknown existence, through this chaotic way, the possibility of basic scientific progress is completely locked. Basic science cannot progress, let alone applied science. If you can't break the seventh-level barrier, you can't get the correct test results, and you can't truly become a seventh-level civilization. And the seventh-level barrier is obviously impossible to break in a short period of time.

So Xiao Yu gave up the idea of impacting the seventh-level civilization now. The technology of the sixth-level civilization has advanced to the peak, and the seventh-level barrier cannot be broken, so these scientists can indeed be idle.

"In the future, I will begin a large-scale manufacturing mission, and I will build at least ten ships with holographic defense technology, at least ten billion remaining warships of various types, and a large number of galactic defenses to fight against the Sweeper civilization. Ladies and gentlemen, if your research encounters a level 7 barrier, then give up for the time being, this is a long-term work, and it is unlikely that there will be a breakthrough in the short term. If your research hasn't encountered a Level 7 barrier yet, it means that there is still potential for the research within the scope of Level 6 civilization, so you might as well continue your research for a while. Okay, that's it, adjournment. ”

When Xiao Yu just said the word "distraction", suddenly a message was transmitted to Xiao Yu's mind. Xiao Yu's face immediately began to become cold, and at the same time, this information was broadcast to the conference hall simultaneously.

"Shenzhou civilization, we are a sweeper civilization."

"As a pair of fatalistic enemies, sooner or later there will be a war between our two civilizations. However, we believe that there is no point or use in destroying the weak you. So we gave you plenty of time to develop, and until now, you have touched the present of the seventh-level barrier. ”

"Your conventional technology has reached its peak, so we think it's time to start the war. But we are not in a hurry, and we know that you are not ready for war. Then let's give you another thousand years, and after a thousand years, our Sweeper civilization will come here and destroy you......"

"The road to the universe is long, and between the two of us, only one is destined to continue to survive......"

With the faint sigh of the Sweeper's civilization, the message ended. Xiao Yu didn't speak, but in the middle of the venue, Xu Junpo's expression changed a little. He kept chanting the words "The road to the universe is long, and between the two of us, there is destined to be only one ...... continue to survive", his expression seemed to be confused, and he seemed to be enlightened, as if this sentence was a key, as if something had been opened in his mind.

At this time, on Planet 8, Yang Jianqi, who was playing a game in his room, had just quit the game under the call of his mother. His face was full of satisfaction, because his village-level spaceship had been upgraded to a township-level spaceship after the battle with the Aotian spaceship.

The Autean ship has been reduced to pieces. (To be continued......)
