"Why don't we take your 'iron-armored monster' to Weijiaji?" When Liu Fei took over the engineering mecha and put it on the wooden raft, Wei Xiong looked at Liu Fei with an excited look and asked.

"That's not a monster, it's a construction machinery. It's not suitable for long-range flight missions, and it can't accommodate the four of us. In addition, I have to save energy combs. It's very consuming energy combs to let a mecha weighing dozens of tons fly into the sky. Moreover, Wei Jiaji has a flat terrain and a wide field of view. It's easy to find when flying in the sky."

"Discovered..." Manny and Meier looked at each other and couldn't help but fight a cold war. It can be imagined that if Liu Fei's identity was discovered, he would become the enemy of the entire Utopian Republic. At that time, a steady stream of enemies would flow over like poisonous bees.

"Oh...what is an energy comb?" Wei Xiong asked with regret.

"The source of power that drives machinery."

"Oh..." Wei Xiong opened his mouth and did not ask again. For him, both the energy comb and the source of power were too profound.

"Does the earth no longer use gasoline or other fuel?" Mei'er suddenly interrupted and asked.

"I didn't use it very early. Nuclear energy has been fully popularized. One kilogram of uranium-235 can release 23 million kilowatt-hours of heat; some cleaner new energy sources are replacing nuclear energy, such as antimatter energy, etc. Because the high-capacity energy comb solves the energy storage problem that has always plagued humans, the energy comb is currently one of the most widely used energy types in the seven major star domains. It replaces the traditional internal combustion engine engine..." Liu Fei understood these technical and data-related issues thoroughly, and he was also happy to explain to Mei'er. He felt a strong desire for knowledge from Mei'er's wise eyes. Liu Fei understood this desire for knowledge, because he used to be the same.

"Seven Star Domains?" Mei'er couldn't stop talking.

"Yes, as early as hundreds of years ago, humans had entered the era of interstellar migration. In these hundreds of years, there are seven star domains that humans have developed and matured, including the Milky Way. However, the earth is currently occupied by aliens, and there are tens of billions of humans living in the other six star domains."

"The earth is occupied by aliens? What is an alien?"

"Alien are a very powerful creature. They can break through the fiber space and move between the star domains without the help of any mechanical power system. Their bodies are volatile and have strong reproductive abilities. They are mainly black and divided into many levels. The highest level known to humans is the five-colored alien. So far, the biggest enemy of humans is the alien. When we came here, the Zoer Star Domain and Morton Star Domain where humans live had already exploded... "

"Then...will humans be destroyed by aliens?"

"No!" Liu Fei made a decisive move: "Humans have very strong potential for war, and humans have advanced scientific and technological weapons. In fact, in addition to weapons, even humans themselves have the conditions to defeat aliens. Therefore, if an alien wants to destroy humans, it is absolutely impossible for them to appear. The biggest possibility is that the war between aliens and humans is in a stalemate. In this case, it is impossible to decide the outcome in a short period of time..."

Liu Fei's conclusion is not optimistic, mainly because it is due to the strength of the five-colored alien. As long as there are individuals like the five-colored alien, the alien cannot be completely eliminated.

"oh!"

Meier and Manny Weixiong looked at each other and breathed a sigh of relief.

"The water flows too slowly, and we may not have enough time to prepare. We have to find a way to speed up..."

Liu Fei stood at the bow of the boat and looked at the moving river banks on both sides. He made a calculation error. He calculated the flow rate of the water, but forgot to calculate the resistance of the wooden raft. In fact, the resistance of the wooden raft is much greater than that of the wooden raft. At this speed, the time will be in a hurry.

Next, Liu Fei made a large number of tools from the space button, including a mini-assisted engine.

This is a charming engine, shining with metallic luster, and extremely finely made, like a perfect craft.

If the engine experts from the six major star fields see this exquisite engine, they will definitely be shocked, because it is a miniature auxiliary engine on a mecha. At present, there is no such small engine in the human world. Judging from this point alone, Liu Fei has made a great breakthrough in miniature engines.

This micro-assisted engine has a great origin. It is a micro-engine developed by the conquest team led by Wang Yifu. Liu Fei has never stopped improving this micro-engine. Whenever he has time, he will use some mechanical manufacturing to optimize this micro-engine.

Liu Fei’s idea is very simple. For Liu Fei, he has never said that he wasted the use of natural resources. He believes that this is a very cost-effective thing. Any type of energy comb can provide strong power for this micro engine.

To change the purpose of the engine is simple, it is actually a vast project. However, this is not a difficult problem for Liu Fei, and he is even familiar with it. What he is best at is modifying the mecha. It is obviously much easier to modify a wooden raft thruster than modifying the mecha.

It is worth mentioning here that although most of Liu Fei's things are placed in Xiaoqiangguang's brain, this does not mean that Liu Fei is "poverty". Liu Fei still has a large number of space rings. In addition to the mechas seized at Zhuoer University, there are also some basic maintenance tools and survival tools.

In fact, what makes Liu Fei depressed is here. He now has a lot of mechas, almost all of which are from the six major star fields. This makes the energy combs between mechas incompatible. Faced with the current harsh environment, he has to avoid using mechas as much as possible. He doesn't want to suddenly lose the energy combs when driving mechas to fight. It will be a disaster.

The warping space of the small strong light brain mainly stores some large equipment, such as some assembly line fully automatic metal analyzers, etc. Of course, it also includes hundreds of eliminated gg-03 heavy mechas.

Whenever he thinks of the things in the warp space of the Little Rising Brain, Liu Fei will have some fantasies. If the Little Rising Brain follows here, he can form an interstellar force based on the equipment and technology it has. He will definitely be invincible. It is estimated that the entire Ideal Star will be liberated in one week. At that time, he can ask for the metal of the Ideal Star.

Unfortunately, everything is fantasy, and it is said to be building an interstellar force. It is extremely difficult to repair the Brave Enterprise.

In fact, if you have the ability to form an interstellar force, it is impossible to lack metal.

Whether it is a dream or a fantasy, it cannot change the reality after all. Liu Fei can only honestly convert the micro engine into a thruster... an ancient propeller thruster.

Liu Fei's modification was not boring for Mei Er and the other three. Seeing various tools and metals sliding and jumping between Liu Fei's fingers, the light and light sparks flashed and various shapes changed. The three of them were fascinated. What made the three of them puzzle the most was that Liu Fei's focused expression was like having a strange charm. Every move would make people intoxicated and unable to extricate themselves.

As the water of the Nujiang River drifts with the waves, time passed by, a brand new machine had already revealed its prototype. A flat mini engine was fixed on a fixed light metal rack. A long metal rod was welded at the tail of the mini engine, and three metal leaves were welded at the other end of the rod.

Finally, it's finished!

Liu Fei stood up, let out a long sigh, lifted the engine with one hand, and walked towards the stern of the boat.
Chapter completed!
