For Xiao Yu, the important thing is not just the corpse of the MSI civilization. In addition to this, the development of conventional technology is also extremely important. The corpse of the MSI civilization can bring Xiao Yu a huge strength boost in an instant, and the development of conventional technology is a necessary condition for advancing to a seventh-level civilization. These two are indispensable.

In the course of more than 100 years of research, in addition to researching the corpse that allowed the ghost clan to manipulate the MSI civilization without damage, Xiao Yu also conducted a lot of research and made certain progress in other aspects of science and technology. In this case, the fragments of stellar-level warships obtained from the Guardian Civilization, as well as those geometry of the Mechanically Oriented Seventh-level Civilization, have become the most powerful source of Xiao Yu's scientific and technological progress. During this time, at least millions of technologies have been parsed by Xiao Yu, and Xiao Yu's technology has improved a lot compared to when he first left the galaxy.

The most obvious data is that Xiao Yu's maximum speed at the moment has reached one hundred and twenty-five times the speed of light, and the combat power of warships of the same class has increased by an average of thirty percent. Xiao Yu even predicted that even from this moment on, without the help of external forces, relying on his own research alone, Xiao Yu was confident that within 100,000 years, he would develop conventional technology to the level of guardian civilization.

"100,000 years is too long, I can't afford to wait. And...... What if my regular tech outranks the Guardian civilization? As long as it does not reach the level of a seventh-level civilization, it will definitely not be an opponent of the Sweeper civilization with conventional technology alone. Hopefully, Xu Junpo can bring me some surprises. Xiao Yu sighed silently.

In this year's time, Xu Junpo has completed the necessary knowledge reserves. His brilliant scientific thinking played a big role in this process. And what Xiao Yu values is precisely this.

In some ways, scientific thinking is indeed more important than scientific literacy. In terms of knowledge reserves alone, the Shenzhou civilization is complete. Even in the whole galaxy, no one can compare to Xiao Yu, but there are some problems that Xiao Yu can't solve, but Luca No. 3, No. 4, Xu Junpo and others, who have relatively little knowledge, can solve them, which is the difference between scientific thinking and scientific literacy.

Research into the corpses of the associated Ghost Race and MSI civilizations is in full swing. The companion ghost clan entered the scientific research spaceship specially built by Xiao Yu, and stayed with the scientists led by Xu Junpo all day long, undergoing various inspections. Xiao Yu even used the most advanced space cutting tools to cut a few milligrams of material from the corpse of the MSI civilization and put it in the laboratory for decades. for scientists to study.

"The corpse of the MSI civilization seems to be made of a completely new substance, it is not a white dwarf, nor is it a neutron star, and our scientific research equipment cannot find any material that conforms to our microscopic theory in the material of the corpse of the MSI civilization. We can't find electrons, we can't find neutrons. No proton was found either. Not to mention quarks and stuff like that. It seems to be a pure collection of energy, and when pure energy is gathered together, it exhibits the properties of matter such as mass and gravity. ”

Mass and energy are complementary to each other, where there is mass, there must be energy, and if there is energy, there must be mass, and there is no pure mass. There is also no such thing as pure energy. However, the corpse of the MSI civilization seems to have broken this perception, it looks like matter, but in fact it is composed of pure energy.

"I think, before starting this study. We first need to get a few things to the bottom of it. At a scientific exchange meeting, Xu Junpo informed all the scientists present, including Xiao Yu, of the current research progress and some difficulties encountered in the current research, "Judging from the fact that the soul can live without the body, and the rest of the characteristics, we have reason to believe that the soul is life, and life is the soul." And the ghost clan is a collection of souls, that is, a collection of life. According to the owner's description, the ghost clan should be regarded as a composite life. Then the question arises, what is the soul, or life? Why is it that after having life, an individual can move freely, and after losing life, an individual becomes an aggregate of ordinary elements? ”

Xiao Yu knew that this problem had entered the most essential category.

Xiao Yu had conducted a similar experiment before, and this experiment was also very interesting. Xiao Yu imitated a living intelligent creature through very advanced biotechnology and created another intelligent creature. This artificial creature has the same height, the same appearance, the same organs, the same blood, and all its physiological indicators are exactly the same as those of the original sapient beings. The only difference is that the body was created by an instrument, while the original sapient beings were born by natural means.

This body has all the health conditions that Xiao Yu knows, but Xiao Yu knows that it is dead, it has no life. This is a paradoxical phenomenon, because this replica has a healthy body, a healthy organ, physiologically speaking, it is alive, but it is dead, it has only the most basic instinctive responses, and it does not have any autonomous consciousness.

Xiao Yu couldn't figure out the difference between the replica and the original intelligent creature, but the difference did exist. Xiao Yu knows that this difference is life. Proto-sapient beings have life, while replicas have no life.

So, what is life, or soul, exactly?

That earth girl, Zhang Shengya used to have life, she used to be alive, but now she has lost her life, so although her physiological indicators are completely normal, she is still dead.

The meeting convened by Xu Junpo continued: "We don't know what life is, but in the current stage of research, we have found some differences between perfect life and imperfect life. ”

"A perfect life is one who has complete control over one's own consciousness. There is an essential difference between this and imperfect life. To put it simply, a large part of the decisions and behaviors that an imperfect life makes, or the emotions it feels, sadness or anger, are caused by changes in the levels of various chemicals in the body. Taking the Luca people as an example, the No. 1 substance will cause emotional impulses, so when the content of the No. 1 substance in a Lucca intelligent creature increases, the Luca intelligent creature will do some impulsive and irrational things, then, doing these things, it is no longer the autonomous consciousness of the Luca intelligent creature, because in the process, it is affected by the chemicals in the body. All of us here, including Luka, are imperfect beings except for our masters and the Spectres. To put it simply, our bodies control our consciousness to a certain extent. ”

In contrast to imperfect life, there is perfect life. Both the master and the ghost clan are perfect beings. Because they can leave their bodies and live alone. The decisions they make are genuinely self-conscious, not influenced by certain chemicals. They feel angry because they are really angry and not because of an increase or decrease in some chemical in their body that controls anger. These feelings are real feelings and have nothing to do with chemicals. This is the difference between a perfect life and an imperfect life. Combined with the origin of the birth of the Ghost Race, we are convinced that only when a large number of perfect beings die, the Ghost Race will be born. And there must be some important connection between the birth and state of existence of the ghost race, and the factor of perfecting the life form. ”

"Therefore, in the next research, we will use the difference between perfect life and imperfect life as a breakthrough. I will make the following arrangements: the Faculty of Life Sciences will be responsible for research related to the body, and the Faculty of Physical Sciences will be responsible for research on the physical properties of the ghost family......"

The difference between perfect life and imperfect life was first proposed by Xu Junpo. Faced with this proposal, Xiao Yu remembered a long time ago, after separating from his body, why Xu Junpo's predecessor, Vicky, had been inexorably weakened, instead of maintaining a constant fluctuation intensity like himself.

Xiao Yu also remembered what the companion ghost clan told him that human beings on earth have souls, while most alien intelligent creatures have no souls.

This is an unsolved mystery that has been haunting Xiao Yu's heart. Now, Xu Junpo's statement has brought Xiao Yu into contact with the origin of this problem, that is, the difference between perfect life and imperfect life.

At this time, Xiao Yu's heart suddenly moved, and he remembered another point.

According to Xu Junpo's classification method, Vicky is undoubtedly an imperfect life, but Xiao Yu confirmed that after being separated from the body, Vicky, who exists in a soul state, will still have all kinds of emotional changes. Like his love for that female intelligent creature. And according to the classification, after Vicky leaves the body, he should not have feelings.

So, is it because of the existence of feelings that Vicky is constantly weakening? Is this weakness based on the same mechanism as the ghost's manipulation of the corpses of an MSI civilization? This is also worth looking into. ”

Xiao Yu thought about it, and after changing the information about Vicky, he handed it to Xu Junpo. Xiao Yu was extremely tightly sealed off during that incident, so Xu Junpo didn't know that his birth had such a bizarre story. The current Xiao Yu also doesn't want Xu Junpo to know this. Therefore, some changes are necessary. (To be continued......)
