Hearing Xiang Gan's answer, Karya smiled and stretched out his hand, and soon countless points of light began to gather on his palm, and these points of light finally condensed into a ten-carat crystal.

"When you get back, put this crystal on the racial scepter, and then we will sign a contract under the rules of the game. The condition is what I said just now, when your human civilization crosses the ninth-level civilization, help me resurrect Xin'er, if you humans do not cross the ninth-level civilization, then this agreement will be null and void. When the rules of the game are in front of you, you can agree to it if you have no problem. Karya handed the crystal to Xiang Qian.

"Okay, I got it. However, I want to know why Mr. Lin thinks that we humans have the hope of surpassing the ninth-level civilization, and isn't the ninth-level civilization the pinnacle of the universe at the civilization level, is there a more powerful civilization than the ninth-level civilization. Xiang Qian nodded, put away the crystal and expressed the doubts in his heart.

"I think you human beings have this potential, although the ninth-level civilization is the pinnacle civilization in this universe, it doesn't mean that the ninth-level civilization can't be crossed. Although I am not a ninth-level civilization, I also know a lot about the ninth-level civilization, but it is too early to tell you this, and when you become an eighth-level civilization, I will tell you all these things.

Even if I say now, I'll delete your memories when you get out of here, so I'm going to tell you what you need to know the most.

From the third-level civilization to the fourth-level civilization, it can be said that it is a turning point in a civilization, before the third-level civilization. It can only be regarded as a low-level civilization. The fourth-level civilization can be regarded as entering the ranks of intermediate civilizations. So it doesn't matter how many third-level civilizations. It is impossible to defeat a fourth-level civilization, and the gap between them is very huge.

At the same time, all Level 3 civilizations are moving towards this step towards Level 4 civilizations. It is also a starting point for the entire civilization technology system, and since the fourth level of civilization, there are few similar civilizations. This is because the fourth-level civilization is a choice for the evolutionary direction of all races, and when this direction is chosen, it basically cannot be changed.

For example, the current technology tree of your human beings is basically based on the third-level technology system of the left-behind civilization that you have obtained in the small universe as the backbone, and the technology researched by you humans yourself is the branch, and the technology tree formed by plundering the scientific and technological data of other civilizations is the branches and leaves.

Such a tech tree would make you humans a fourth-level civilization. You human beings are also at the bottom of the fourth-level civilization. This is because the trunk of your tech tree is obtained from the left-behind civilizations, and the tech trees used by all the left-behind civilizations in the small universe are called the universal basic tech trees of the universe.

This kind of tech tree is universal to the whole universe, and it is also the most basic, without any racial characteristics, and any civilization that gets such a tech tree can be integrated into its own tech tree.

Although you have now broken through the basic materials science to the level of a fourth-level civilization with the help of this technology tree, it is not a complete level 4 civilization technology. Because the basic material discipline of any fourth-level civilization is to serve the development direction of the overall civilization. Therefore, your current basic materials discipline can only be said to have found the right way to break through the fourth-level civilization.

Only put the scientific and technological data of all civilizations. When all of them are integrated into your own scientific and technological system, forming the technology that is unique to your human beings and is the most suitable for you, that is when you break through the fourth-level civilization. ”

"But there are so many left-behind civilizations in the whole universe, and it is difficult for each left-behind civilization to be different. The living environment is different, so why is the scientific and technological system they studied the same? Xiang Qian said suspiciously.

"Whoever said that those technology systems were researched by them, the third-level civilization technology tree you got was just snatched by the left-behind civilization from the previous left-behind civilization. You don't have to ask where these third-level civilization technologies came from in the first place. All I can tell you is that it's the rules of the game.

This tech tree is spread throughout the universe, and I don't believe you will leave the galaxy in the future. Reach a higher level of battleground, where you can ask a civilization to see if they have the same tech tree they have gotten before. ”

"What is the technology system unique to the race? Is there any difference between that and using the current tech tree to break through to a level 4 civilization? Xiang Qian continued to ask.

"The gap is big, this gap is not obvious in the early stage, but when it comes to the fifth-level civilization and the sixth-level civilization, it is enough to make you desperate. To say that it will be deleted when you leave, there is no hope of breaking through the seventh-level civilization by using the general technology tree to break through the fourth-level civilization, and only the civilized race that forms its own race-specific technology system when the third-level civilization is qualified to break through the seventh-level civilization.

As for race-specific technologies, it is difficult to describe, because each race has its own unique technology, and the difference is only how many special technologies occupy the overall technology tree. I'll show you a video and you'll know, it's more intuitive than I said. ”

With a wave of his hand, the scene in front of Xiang Qian's eyes turned into an endless starry sky, and they sat in the void.

Xiang Qian subconsciously wanted to stand up, but when he felt the touch coming from the seat and under his feet, he immediately stopped his movements and sat quietly on the chair.

At this time, in the starry sky in front of Xiang Qian's eyes, ripples like water ripples suddenly appeared in the space, and then an incomparably huge planet appeared in front of them. The planet has no atmosphere, no mountains, no rivers, not even oceans, and looks like a giant black-brown glass ball.

"This is a group of biochemical sixth-level civilization races, and their technological route is biological evolution and energy evolution, that is to say, when they break through the fourth-level civilization, they use biotechnology and energy technology as the framework of the technology tree, and then go all out to climb these two disciplines, and finally become a sixth-level civilization.

For this race, as long as there is matter, they can transform it into energy and nutrients, and produce endless biological weapons. Unless you can blow up their brood with a single blow, you'll be consumed by an endless array of biological weapons, which is a very difficult civilization to entangle with in a level 6 civilization. ”

With Karya's explanation, Xiang Qian's biochemical civilization in front of them encountered a rocky planet. The entire planet cracks open like petals, and then directly envelops the entire rocky planet inside. Next, countless large holes with a diameter of several hundred square kilometers appeared on the surface, and then from these holes, endless monster-type biological weapons appeared.

See such a situation. Xiang Qian's first reaction was two words, Zerg. This is the real Zerg, look at the body that is hundreds of thousands of kilometers long, and the huge claws that can cut the moon directly. Compared with these biological weapons, those biological weapons made by condensation are simply single-celled organisms.

Then the image in front of their eyes changed again, and this time in front of them was a huge steel planet, and outside of this steel planet, there were dozens of metal rings. The metal rotates slowly. Among them, Xiang Qian also saw countless warships with hideous guns.

"This is a sixth-level mechanical civilization, and their scientific and technological route is mechanical power upgrading and energy discipline assistance plus life transformation, that is to say, when they break through the fourth-level civilization, they are a science and technology tree composed of mechanical technology, energy technology, and biotechnology, which are three kinds of technology, and they gradually abandon biotechnology in the future, mainly climbing the first two technologies.

They are a strange race, they were originally a human-like civilization, but after they became a fifth-level civilization, they gradually began to transform their lives. Transform carbon-based lifeforms into silicon-based lifeforms, and when they become sixth-level civilizations, all the clans of their entire civilization have already become silicon-based lifeforms.

Their combat power is very strong, and they are also the nemesis of biochemical civilizations. Because many of the weapons of biochemical civilizations have no effect on them at all, while their weapons are deadly to biochemical civilizations, especially their main planet. All of them are war fortresses made of special rare metals, and their attack power is among the best among the sixth-level civilizations. ”

Xiang Qian looked at the metal planets of various shapes in front of him. He couldn't complain anymore. It's a zerg just now, and the shape is even a transformer. I don't know what other strange races will appear later.

Karya really didn't disappoint Xiang Qian, and the races that appeared next became more and more bizarre.

What energy class upgrades the civilization race, the technology tree is based on energy technology and quantum theory, and the entire race has been transformed into a pure energy body, even the home planet has been transformed into a huge energy crystal, what positive matter when fighting, antimatter, negative matter, annihilation, death light, etc., as long as it is an energy attack, they will not be. And when there was no ceasefire as soon as the fight started, it was completely a mobile battery, and the firepower Xiang Qian was afraid to watch.

There is also a pure material class to upgrade the civilization race, and the technology tree is based on basic material technology and gravitational theory, transforming the entire planet into a white dwarf battle star, and then upgrading to a neutron battle star, and finally becoming a quark battle star when it reaches the sixth level of civilization.

When fighting, there will be no means of energy attack, and there is no need for protective shields, for them, there is only one word to fight, bump. Xiang Qian also watched a scene of their battle, which was called a murderous, completely unreasonable sideways walk, rampaging across the entire battlefield until all the opposing warships were scrapped.

For two hours, Xiang Qian and Condensation had been looking at the various strange races in front of them, and at the same time listening to Karya's explanation, they didn't even have a chance to interject.

"Okay, let's talk about this first, the planet fortress you left outside was discovered by a pioneer civilization, and I think you are leaving." Three hours later, Karya said suddenly.

"Thank you, Mr. Lin." Xiang Qian said gratefully.

"Don't thank me, I just hope that you can become a ninth-level civilization faster, and then cross the ninth-level civilization to help me resurrect Xin'er."

"Mr. Lin, rest assured, as long as we humans really cross the ninth-level civilization, we will definitely do our best to resurrect Miss Xin'er."

"Well, this is something I haven't finished telling you yet, as well as the third-level civilization science and technology materials I have collected over the years, I hope it can be helpful to you. Now I'm sending you away, and the 5oo warriors will be with you.

Goodbye, I hope that the next time we meet, you will have become a seventh-level civilization. Karya said with a smile.

"Mr. Lin, goodbye."

Brush!!!

In the next second, Xiang Qian and Condensation appeared in front of the Xingchen, and at the same time, the soldiers of the Special Brigade were also beside them.

"Chief, why are you here, aren't we dead?" A soldier saw Xiang Qianhe and condensation, and said stupidly.

They had just chosen to sacrifice, and then when they opened their eyes again, they saw Xiang Qian and Condensation right in front of them, and such a huge contrast made it difficult for them to adapt for a while.

"Everyone is not dead, as for why they are waiting for the next way back, they are saying that they choose everyone to enter the Star, and we will return first." Xiang Qian smiled and said.

"Ah...... None of us died...... Yes, long. ”

The people of the special squad only appeared at this time, and the few people who had disappeared in the hall also appeared.

The Star lifted off and departed quickly. (To be continued!)
