Mr. Mu was in a good mood and began to explain: "For thousands of years, the Milky Way has been war-torn, and countless civilizations are intertwined. The reproduction speed and growth cycle of human beings are short, so the development momentum is the strongest. Although there are few areas outside the Milky Way, the Milky Way is basically the world of human beings.

It is not possible to fight the country by equipment, without spacecraft. Over the past tens of millions of spacecraft have been produced and manufactured, so spacecraft can also be divided into ten levels according to the comprehensive values ​​of energy intensity, attack power, defense power, and special abilities. Each level is divided into three grades, middle and lower. Of course, ordinary people cannot involve this knowledge, because civilian spacecraft is only the worst level ten lower grade. Generally speaking, the combat standard ships in the Galaxy Alliance are eight-level top grades, and they can't even make it seventh level. According to this concept, you should have some general understanding of the division of spacecraft, right?" Mr. Mu looked at Yi Shuihan.

Yi Shuihan learned that this evaluation level is very abnormal. The combat ships in the alliance are top-grade eighth grades. What should a spaceship within the third grade look like?

Mr. Mu also said: "The good or bad spaceship and strong attack power only indicate the strength of a single body. No matter how good the spaceship is, it cannot deal with many enemies. Alliance combat ships are often organized and organized. No matter how good the spaceship is, it is useless. Hundreds are not enough for thousands, or even tens of thousands, so don't be stupid enough to think that if you have high grades, you can be invincible. That's incorrect."

After saying that, Old Master Mu added another sentence: "But the high-quality spacecraft will definitely be much better than the lower-level ones when they escape."

"Grandpa, what grade does this giant dragon spacecraft belong to?" Yi Shuihan asked hurriedly.

Mr. Mu stroked his silver-white beard and said happily: "I just got in touch with the master's brain of the spacecraft. Everything here is designed with energy crystals and cutting-edge biochemical technology. It has absorbed energy in the center of the earth for thousands of years. According to the comprehensive ability, it must be at least a second-level medium-grade!"

Yi Shuihan sighed, "Is it only of the second-level mid-level? I thought it was the first-level."

Mr. Mu chuckled and said, "I'm still an insufficiency boy. Do you know that this thing has absorbed the energy of the center of the earth for thousands of years. When we came in, the flare erupted in the core of the earth. He was the one who sacrificed the lifespan of a planet to nurture this spaceship. It can be seen that this spaceship is not easy. I dare say that the emperors of every country in the Milky Way cannot have such a level spaceship, but now my grandfather has one. Those first-class spaceships are all imagined and have not existed yet. When humans designed the level system, they left room for improvement. After all, they cannot guarantee that a better spaceship will be born in the future. Do you think?"

Yi Shuihan nodded in agreement, and Mr. Mu took him forward.

When I came to the control room, it was the center of the dragon's brain. The interior was decorated with antique charm, with beautiful and beautiful flowers, supplemented by cyan crystals, mainly purple crystals, and the light screen in the middle.

Mr. Mu manipulated the light screen, and the screen showed the situation in the underground hall. He saw the rare crystals everywhere, all of which were good things that increased energy and the source of energy in the spacecraft. Don’t be idle.

The dragon's body was about three thousand meters long, and the dragon's scales suddenly reflected tens of light, and then all the crystals were shattered and dropped. The dragon's mouth was wide open, and the powerful traction light swept the hall clean. Fortunately, the storage room in the dragon's body had a dimensional space effect, otherwise it would not be able to swallow so many energy crystals.

After clapping his hands, the completion of the work, Mr. Mu became happier.

"Grandpa, let's go out of this tomb. Maybe this spacecraft can take us back to the ground!"

Mr. Mu waved his hand and said, "Don't be busy going out first. It's very simple to go out. I want to explain some things and decisions to you first."

After saying that, Old Master Mu called out, "Guanglong, come out."

With a shout, a slender light dragon appeared in the room. It was about two meters long, which was similar to the image of the spacecraft, but it was too small.

"Give me the key to the next tomb." Mr. Mu ordered. Guanglong quickly pulled a small box from a wall in the room, and then brought a piece of metal block with the traction beam.

"Han'er, I'll leave this thing to you. If you are interested in the future, you can go to the fat man's tomb, but remember to wait until your own abilities grow before going. This key will be given to you. I'm old and it's time to retire and enjoy my happiness. I'm satisfied with having a good grandson like you take over my class."

Yi Shui said in a heart-warming way that I will take over your work, would I also want to rob the tomb?

Mr. Mu laughed as if he understood his thoughts: "Child, everything is as good as you want. Your ability will be very strong. You will be wronged by staying on this planet with your own conditions. In addition, the core of this planet does not have much energy. Although the planet will not explode, it may fall into an era of ice or dead silence, and the conditions will become worse and worse. If you have the opportunity to go out and stroll, grandpa, I can only take you for another three months, which is to lay the foundation for you in the future."

Yi Shuihan was very moved. Mr. Mu would never repay his cultivation in this life. He vowed in his heart to repay Mr. Mu and his family well in his lifetime.

"By the way, the crystal robot on the Light Dragon spacecraft will be repaired quickly through the Light Dragon spacecraft. Grandpa tried every means to strengthen the pyramid and strive to upgrade it from a fifth-level low-grade spacecraft to a fifth-level top-grade spacecraft. In addition, the energy crystals of the fat man nurturing Light Dragon will be freed up for you. In the future, the energy of the spacecraft and the little thing on your head cannot be separated from energy. You should pay more attention to the collection and saving of energy. Only in this way can you cross the Milky Way."

Yi Shuihan asked foolishly: "Grandpa, can you say you want to give me the pyramid of light? "

Mr. Mu laughed and said, "Silly child, if I have a better spaceship, what do I need to do? It is natural to leave it to you.

Yi Shuihan was ecstatic: "Oh my God, I can actually ask myself to own a legendary spaceship. I am so lucky, and it also fulfilled my childhood dream."

Yi Shuihan accepted the metal square found by Guanglong. This thing is very strange and can be arranged and combined into different shapes, as if it is a three-dimensional puzzle toy. After studying it for a while, there was no change. Yi Shuihan put it into the ancient ring.

Mr. Mu said again: "Child, I'll give you another necklace. I've never used this thing, because it's a bit like something girls use, but you're different. You can't always bring a spaceship with you when you walk. There's still a lot of space when you put the spaceship in. The energy crystals you collect can also be put in." After that, the old man took out an exquisite necklace.

The necklace is divided into three layers inside and outside. Each layer is made of different crystals, with dense patterns engraved on it. The center is a red gem, which is not much different from the special style necklaces sold in jewelry stores, but it is just more exquisite.

"Hehe, this necklace is good, but it doesn't have to recognize the owner, but there is a special way to start it up. It's useless for others to take it away. I'll teach you."

Yi Shuihan quickly learned how to use it and put it on his chest. He didn't think there was anything wrong with a girl's necklace. It would be a pity if such a good thing was not used.

"Okay, let's go out. In the future, your strengthening will be more effective in the light dragon. There is also a physical and mental strengthening system here, and it is very powerful."

After saying that, Old Master Mu controlled the light dragon to fly towards the top of the hall, and opened a passage there, and the two of them finally came out of the tomb.

The days that followed were even more nervous. Mr. Mu filled Yi Shuihan's courses, astronomy, geography, and especially history. In the end, there was nothing we could do. Mr. Mu spent his time making a bracelet for Yi Shuihan. This thing had no other function. It was just a database. And some secrets that the old man knew were lost, so that Yi Shuihan would be able to read it later.

However, the old man often practiced with Yi Shuihan, so he could grasp the key to the coordination between the spirit and the body. He also taught him a set of exercises for internal breathing practice and a set of methods to exercise his mental power. That is, the old man had this kind of trick, and all the things passed on to Yi Shuihan were found in the tombs and were things that only the royal family could enjoy. As for the name of the exercises, the old man named Yi Shuihan and took whatever he wanted. These things were all lost in history. In the opinion of Mr. Mu, he taught him the skills.
