Elder Mensa spoke, and Lei Yaotian gently patted Monica's little ass and balls, letting her get off his lap. Lei Yaotian leaned sideways, leaning on the armrest with his elbows to show a listening look.

"What do you have to offer?"

Mensa looked at Lei Yaotian very seriously and said, "Since you want to join a certain force, then you must have a relationship with the creatures within a certain force. And I don't think you're going to be willing to live like this for the rest of your life after you join, right? So my suggestion is that if you have a choice, then it is best to choose the 'Shenyao Empire' on the periphery of the Savage Star Field. ”

"There are many civilizations in the universe, why do you choose the 'Divine Glory Empire'?"

Lei Yaotian was very puzzled by this.

Elder Mensa seemed to know that Lei Yaotian would have such thoughts, so he explained to him in a good time: "First of all, the Shenyao Empire's sphere of influence is closest to the Barbarian Star Domain, which means that you can quickly get some assistance from our base in the Shenyao Empire, which is an advantage. ”

Lei Yaotian nodded undeniably, and at the same time said in his heart: "I have the golden finger of the plane trader, even if I can't get the base replenishment for a while, I can buy some urgently needed materials from the plane trader." Of course, if I have enough credits......"

Of course, Elder Mensa, Lei Yaotian's little secret, would not know, and he continued: "The second point is that I just have some documents and photos in my hand, and there are some things that can be easily accepted by the Shenyao Empire and become a subject of the empire. Compared to blending into other civilizations, the Divine Glory Empire is the easiest. ”

"The third point is that the Shenyao Empire is not ranked low among the many civilization races in the universe, although it is not the highest civilization level, but it is also ranked in the sequence of middle and high-level civilizations. Therefore, it is recommended that you choose the Divine Glory Empire. ”

"Cosmic civilization level?" , Lei Yaotian heard this for the first time.

Elder Mensa looked at Lei Yaotian and said, "Since that's all I said, then I need to explain to you the situation in our universe well, because you don't know a lot about the situation at that time." Originally, you asked me to learn some relevant knowledge and culture, but we haven't talked about that yet. But now that you have the idea of going out, I need to teach you these things in advance. ”

"Teacher, you say, I'll listen."

Lei Yaotian stared at Elder Mensa very seriously, for fear that he would miss something.

"There are countless civilizations in our universe, but everyone's development is different. Some are very well developed, while others are very low. And the path of development is different, and some are taking the route of scientific and technological development. Some civilizations, on the other hand, have taken the path of developing individual powers, but with the advent of the era of the universe, there have been more exchanges between civilizations. The whole universe seems to have shrunk ......."

"Therefore, in order to protect those civilizations that are still very low-developed, the three most powerful advanced civilizations in the universe have established a 'Pan-Universe Alliance'. All the civilizations found in the universe are recorded one by one. And the known civilization species were divided, and protection decrees were issued. ”

"Teacher, what is the division system of civilized creatures?"

Lei Yaotian interjected and asked.

"That's what I'm going to tell you." , Elder Mensa replied. "The three advanced civilizations list the ten major civilization classes, each with ten levels. Basically, they are determined according to the development of their own scientific and technological civilizations, and all civilizations are divided according to such rules. ”

"The civilization that has just been able to get out of the home planet has been identified as the lowest civilization. Because they can only use some satellite equipment to detect the surrounding situation, they do not have the technology to be able to move freely in the interstellar space. ”

After listening to Elder Mensa's words, Lei Yaotian thought to himself, "It seems that if my original hometown is placed in the current universe, it must be the lowest civilization. Because of the scientific and technological level of his hometown, he is still at the level where he can only launch satellites. ”

Elder Mensa continued: "With the development of science and technology, after being able to immigrate their own civilization species to other planets and successfully develop other planets to settle down and survive, such a civilization can improve its rank, because the development of civilization technology at this time has been able to prove that they have initially mastered the technology to survive in the universe. ”

"This is a tenth-class civilization, and this civilization is divided into ten levels. Of course, you can understand it as the ten stages of the development of civilization, so you can understand it better. ”

As soon as Mensa said this, Lei Yaotian understood.

"The lowest class of civilizations must master the ability to immigrate creatures from their home planet to other planets. It seems that his original hometown still has a long way to go. ”

"Teacher, what about other civilization levels?"

Lei Yaotian continued to ask.

Elder Mensa changed the posture of his body, and it was always a bit tiring to be in one position.

Lei Yaotian turned around and greeted Monica, "Monica, move the sofa out of the room." I've been sitting in this chair for a long time, and I might have been talking to the teacher for a long time. ”。

"Okay, young master."

Monica walked into the room and quickly moved two sofas.

This girl who changed from the brood has a lot of strength, and the two single sofas are completely trivial to her.

One in one hand, it was easy to take it out.

"Hmm~ The little girl has a lot of strength."

Elder Mensa complimented Monica.

You must know that the strength of the Ikerts is not so great. They're just very good at making money, and they're timid and cowardly......

I put the two single sofas on the edge of the lake, and moved the wooden coffee table over. After Monica placed the snacks and milk tea one by one, she greeted Lei Yaotian.

"Young Master, you and Teacher Mensa can sit down."

Lei Yaotian stood up and made a 'please' gesture.

"Teacher, let's go talk over there. Stay in the evening and have a light meal. It seems that you will not be able to go so early today, so we still have to talk. ”

"Hehehehe"

Elder Mensa smiled indifferently, and said as he walked, "Then I will eat more at night, young master, the food you eat is much more abundant than what we eat." ”

What Elder Mensa said was not casual remark, the food that Lei Yaotian ate was all bought from Andrew's plane. All kinds of meats and seasonings were available, and compared to the food rationed to the Ikt people every day, Lei Yaotian ate much better than them.

Although the ration food received by the Iqt people is not very difficult to eat, they always eat a food that has no new tricks and new flavors, and they will get tired of eating it after more than half a year.

That's why Elder Mensa has such a statement.

The two of them came to the platform near the lake and sat down, Lei Yaotian said to Mensa: "For the time being, the teacher's clan will have to endure for a while, after all, our current development is not over. When the development is over, I'll ask the housekeeper to figure out a way to grow some of your favorite food and vegetables on the mountain, so that you don't have to eat rations. ”

"Thank you very much."

After receiving Lei Yaotian's promise, Elder Mensa hurriedly stood up and bowed slightly to Lei Yaotian.

Although Lei Yaotian is his student, he is also the master of these people. Elder Mensa, who is about to become a master, how could he think that if he is Lei Yaotian's teacher, he can stop doing façade work.

Lei Yaotian waved his hand and said, "These are all trivial matters, let's continue to talk about the topic." ”

After Elder Mensa sat down, he continued to explain to Lei Yaotian how to distinguish the levels of the cosmic Chinese species.

"As we mentioned earlier, a civilization can only become the lowest level of civilization if it has the level of technology and can immigrate to another planet. And this kind of technology is an important part of the first order to the second order, and every civilization has to go through such a development. ”

Lei Yaotian listened very carefully to Elder Mensa's story.

"But you know, it's easy to immigrate to other planets. However, the ecological environment of each planet is different, and not every planet can allow living creatures to survive, so second-order civilizations must master the technology of terraforming, even if the technology is very simple, just use some metal plates to build habitable houses on a barren planet, and must do so. ”

"Gravity and survival?" , Lei Yaotian asked tentatively.

Elder Mensa nodded, "Not bad! Throughout the entire stage of the second-order civilization, this field must be explored. When they can fully adapt to any planet, then this civilization can be judged to be third-order. ”

Lei Yaotian knew that what Elder Mensa said was easy, but it was not so simple to do.

To fully adapt to the gravity and environment of a planet, it is necessary to transport materials to transform. This is a very huge project, and it seems that a civilization is already very powerful when it reaches the second order.

"And what about my teacher, the third-order civilization?"

Elder Mensa picked up the milk tea and took a sip, saying that his throat was a little dry for a long time.

"Ha~~"

With a pleasant sigh, he put down the cup and turned his head to Elder Mensa continued: "When a civilization can adapt to survive on any planet, then it is bound to expand its ambitions, and then it will continue to expand the speed of immigration. But you have to know that the distance between planets is not as simple as the distance between the planets and the ground. ”

Lei Yaotian nodded.

"The distances between the planets in the universe are all measured in light years. So a civilization wants to expand its civilization territory, immigrate people to more planets, and solve its population pressure. In this way, it is necessary to have strong inter-space navigation ability and technology, and only then can we explore those distant planets. ”

Therefore, the third-order civilization must master the mature technology of long-distance space travel. The entire stage of the third-order civilization must be developed around the space navigation technology, and finally serve as the gateway to the fourth-order civilization. ”
