"Formally introduce myself, the leader of the earth's civilization, Ruan Lin."

Ruan Lin closed his eyes and motioned for the Kane people in front of him to turn off the camera.

They also shed tears at this time, and Cado beside them was already in tears. Today is destined to be a day that will be recorded in history.

Ruan Lin stood up and stretched out his right hand.

Kado also understood what he meant, and he stretched out his right paw and grabbed Ruan Lin's hand tightly.

He sobbed and said, "I'm sorry, Mr. Ruan. To make you smile, this may be the happiest day of my life, if we have something you need, please feel free to ask! ”

Ruan Lin smiled: "I'll mention this when I'm ready to leave!" The main problem now is to teach you how to build your ship and how to use it to get your engine. ”

"Until then, I want you to reconcile with your son. Kaze, he should be completely awakened by now, he is indeed a malleable talent. ”

Ruan Lin accompanied Kado downstairs, and at this time Kaze was already kneeling downstairs in the Elder's Mansion.

His eyes caught glimpse of Ruan Lin and Kado, and he sobbed: "I was wrong, father! My thinking was too radical. Mr. Nguyen! I'm so sorry, I've repented now, I was so wrong. ”

Ruan Lin hurriedly walked to Kaze and helped him up: "You can change it after that, and it is very good!" ”

The camera behind him captured this image in time, and this picture was later called "The Beginning of the Stars". Kaze also became the best captain of the Kahn Civilization Fleet, but that's all for later.

"Next, it's time to start teaching you how to make ships!"

Nearly all members of the entire Kahn civilization were mobilized for this ship-building project, and they took turns to carry out survey and mining work on the surface. Ruan Lin also sent all the robots to land on the planet Kahn to help them complete their work.

And the scientists of the Kahn civilization completely let Ruan Lin know what madness is, Ruan Lin can do it without rest or eating, and he can't be counted as a real organism now. He imparts knowledge in the largest conference room at the University of Kahn, and his mouth barely stops.

He was facing hundreds of the most famous scientists of the Kahn civilization.

Their scientists only take a break to eat almost every twenty hours, and several professor-level Kahn people have been forced to rest by Ruan Lin, and they will die suddenly if this continues!

In the course of the constant exchanges, Nguyen Lin also learned about the common age of survival of the Kane people, who lived up to 300 earth years. When they are in a harsh environment, they can take the initiative to "hibernate", which also amazes Ruan Lin.

Most importantly, the Kahn civilization had few weapons of mass destruction, and their civilization had not been at war since the Horde period.

Sure enough, every civilization has its shortcomings, and it also has advantages that are favored as soon as it is born.

Regarding the level 4 civilization and level 6 civilization in the mouth of the Titan civilization, Ruan Lin speculated that it may be recognized as a level civilization after mastering a certain technology, which seems to be a consensus. And if you have mastered controlled nuclear fusion, can you classify it as a level 2 civilization?

Geoscientists have long had fantasies about this.

However, it is too monotonous to certify oneself as a civilization of several levels by virtue of a certain aspect of technology, and does not take into account the number of members, the number of ships, the sphere of influence, and the leading technology in some aspects.

For example, one day a civilization has just developed controlled nuclear fusion technology, and they should logically be classified as a level 2 civilization.

But then they broke through the limits of biotechnology, reaching a level that even Level 6 civilizations look up to, and each individual can survive for hundreds of millions of years, so what level of civilization are they?

This seems to be a paradox, Ruan Lin can say that this civilization is a level 6 civilization, but on the other hand, they are not a level 6 civilization either.

They have biotechnology that has not been discovered by any level 6 civilization, but they also do not have the weapon technology that level 6 civilizations have.

This may be the technology tree that is often said on Earth, and each civilization has its own specialized technology. One aspect of technology is regarded as the main breakthrough goal of civilization, while others are complementary developments.

The universe is so big that there are no surprises.

Maybe in the future, you can still meet civilizations that specialize in computers, and their computers can't even be imitated by level 6 civilizations, which other civilizations can't do, so how many levels of civilization are they?

Ruan Lin felt as if he had fallen into a strange circle, the definition of the level of civilization in the universe was too simple, and the final answer needed to be found out by himself.

At this time, 10 years have passed since Ruan Lin arrived on Kahn Star, and with the help of Ruan Lin, they have made great progress from scratch from scratch to master the theory of controlled nuclear fusion.

They succeeded in building the first meteor-class destroyer of their own civilization, the Kahn, and completed the controllable fusion engine and basic laser weapons.

Ruan Lin also ushered in an improved laser weapon, as well as a kinetic weapon that he had previously completed during his journey, the electromagnetic railgun.

It looks very similar to the anti-aircraft guns on Earth, it consists of two parallel rails, and the projectile is sandwiched between them.

It doesn't have a blue beam of light when it is fired like in a science fiction movie.

Nguyen Lin set them up as a mobile electromagnetic turret, and the accelerator barrel was not set very long. In pursuit of the ultimate rate of fire, each projectile was designed to be small, and at the time of testing, the initial velocity of the projectile reached 10 kilometers per second, and it could be fired twice per second. Each ship is also equipped with ultra-high power energy.

The electromagnetic railgun is like a prize, shooting at the enemy fleet indiscriminately, and if there is a target that is shot, it will win the jackpot, and its main role is to hinder the movement of enemy ships and excessive approach, which is like the anti-aircraft guns on the ships of the Earth Navy.

At present, the most important weapons of destruction still rely on laser weapons, and their firing speed is basically the same as the speed of light.

Nguyen Lin's fleet has also been replenished, relying on the space dock, the number of meteor-class destroyers has been built to 630, and the comet-class destroyer has only one more "Atom". The exterior materials of each ship are made of thermal insulation materials of the Kahn civilization.

Ruan Lin's next step is to build a large particle collider to explore new particles and microscopic quantized particles.

Now, it was time to say goodbye, and Ruan Lin had no other scientific knowledge to teach them.

In the conference room, Ruan Lin said slowly to Kado beside him: "Mr. Kado, tomorrow our earth civilization will leave. ”

Kado met Ruan Lin's gaze as if they had met for the first time: "I know that Ka'en Star can't keep your civilization, thank you for teaching our civilization in these 330 Ka'en years, I have the highest respect for your civilization." ”

This time, he took the initiative to extend his right paw.

Ruan Lin stretched out his right hand and grabbed his right paw tightly, shaking it up and down twice.
