"Why don't we take your 'ironclad monster' to Weijiaji?" When Liu Fei collected the wooden platoon on the engineering mecha, Wei Xiong was excited and looked at Liu Fei eagerly and asked.

"That's not a monster, it's a construction machine, 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, it is very energy-consuming to let a mecha weighing dozens of tons fly into the sky, not to mention, Wei Jiaji has a flat terrain and a wide field of vision, and the mecha is easy to be found when flying in the sky."

"Discovered...... Manny and Mei'er glanced at each other, and couldn't help but fight a cold war, it is conceivable that if Liu Fei's identity is discovered, he will become the enemy of the entire utopian republic, and when the time comes, a steady stream of enemies will continue to pour over like poisonous bees.

"Oh...... What is Energy Ctenophora? Wei Xiong asked with a look of regret.

"The source of power that drives machinery."

"Oh......" Wei Xiong opened his mouth, but he still didn't ask again, for him, whether it was the source of energy or power, it was too profound.

"Doesn't the earth use gasoline or anything like that as fuel?" Mei'er suddenly interjected.

"It has long been discontinued, nuclear energy has been fully popularized, and 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-capacitance energy ctenophore solves the energy storage problem that has been plaguing mankind, so the energy ctenophore is currently one of the most widely used energy types in the seven star fields, it replaces the traditional internal combustion engine engine...... "Liu Fei has a thorough understanding of these technical and data problems, and he is also willing to explain to Meier, he feels a strong desire for knowledge from Meier's wise gaze, Liu Fei understands this desire for knowledge, because, He used to be like that.

"Seven Star Fields?" Mei'er suddenly closed her mouth.

"Yes, as early as hundreds of years ago, human beings have entered the era of interstellar migration, and in these hundreds of years, there are seven star fields that have been developed and matured by human beings, including the Milky Way, however, at present, the earth is invaded by aliens, and tens of billions of human beings live in the other six star fields."

"The Earth is invaded by aliens? What is an alien? ”

"Aliens are a very powerful kind of creatures, they can break through the fiber space, without the help of any mechanical power system can move between star fields, their shapes are changeable, have a strong reproductive ability, mainly black, divided into many levels, the highest level known to humans is the multicolored alien, so far, the biggest enemy of mankind is the alien, when we came here, the Drow Star Domain and the Morton Star Field, where humans live, have broken out the alien disaster......"

"That ...... That...... Will humanity be wiped out by the Xenomorphs? ”

"No!" Liu Fei said categorically: "The war potential of human beings is very strong, and human beings have advanced scientific and technological weapons, in fact, in addition to weapons, even human beings themselves have the conditions to defeat aliens, so if aliens want to destroy human beings, it is absolutely impossible to appear, the biggest possibility is that the war between aliens and human beings has fallen into a stalemate, in this case, it is impossible to distinguish the winner in a short period of time......

Liu Fei's conclusion is not optimistic, mainly because of the strength of the multicolored alien, as long as there are individuals like the colorful alien, it is impossible for the alien to be completely eliminated.

"Oh!"

The three of them looked at each other and let out a long sigh of relief.

"The water is flowing so slowly that we probably don't have enough time to prepare, so we have to find a way to speed it up......"

Liu Fei stood at the bow of the boat, looking at the moving 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 boat, according to this speed to rush to Weijiaji, the time will be very rushed.

Next, Liu Fei pulled out a large number of tools from the space button, including a miniature auxiliary engine.

It is a fascinating engine, shimmering with metallic sheen, and extremely finely crafted, like a perfect piece of artwork.

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

This miniature auxiliary engine has a great origin, it is the miniature engine researched and developed by the team led by Wang Yifu, Liu Fei has not stopped improving this miniature engine, and whenever he has time, he will use some mechanical manufacturing to optimize this miniature engine.

Liu Fei's idea is very simple, to install this micro engine on the wooden row to speed up, for Liu Fei, there has never been a violent thing, he thinks, this is a very cost-effective thing, any model of energy can provide strong power for this micro engine.

Changing the purpose of the engine is simple to say, in fact, it is a vast project, but this is not a problem for Liu Fei, and even he is familiar with the road, what he is best at is modifying mechas, and it is obviously much easier to modify a wooden row thruster than to modify mechas.

It is worth mentioning here that although most of Liu Fei's things are stored in Xiao Qiangguang Brain, this does not mean that Liu Fei is "poor", Liu Fei still has a large number of space rings, which contain some basic maintenance tools and survival tools in addition to the mecha mecha seized at Zall University.

In fact, what makes Liu Fei depressed is here, he now has a lot of mechas, almost all of the mecha in the six star domains, which causes the energy crotch between the mecha to be incompatible, in the face of the current harsh environment, he has to avoid using the mecha as much as possible, he doesn't want to drive the mecha to fight and suddenly have no energy, it will be a disaster.

In the warping space of the small strong light brain, some large equipment is mainly stored, such as some automatic metal analyzers of assembly lines, etc., and of course, hundreds of obsolete GG-03 heavy mechas.

Whenever he thinks of the things in the warping space of the little Qiangguang brain, Liu Fei will have some fantasies, if the Xiaoqiangguang brain follows here, it can completely form an interstellar force according to the equipment and technology it has, and it will definitely be invincible, it is estimated that the entire ideal star can be liberated in a week, and when the time comes, he can take the metal of the ideal star.

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

In fact, if there is the ability to form an interstellar force, it is impossible to be short of metal.

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

Liu Fei's modification is not boring for Mei'er and the three of them, watching all kinds of tools and metals slide and jump between Liu Fei's fingers, and between the flashes of photoelectric sparks, they change into various shapes, the three of them are fascinated, and the most mysterious thing for the three of them is that Liu Fei's focused downward movement is like having a strange charm, and between gestures, it will make people intoxicated and unable to extricate themselves.

As the time passed, a new machine was revealed, on a fixed lightweight metal shelf was fixed with the flat miniature engine, the tail of which was welded with a long metal rod, and at the other end of the rod, three metal blades were welded.

Finally, it's done!

Liu Fei stood up, exhaled a long breath, lifted the engine with one hand, and strode towards the stern.

Watching Liu Fei walk to the stern, the three of them were stunned, especially Wei Xiong, with his mouth wide open, with a shocked look on his face, he was helping to clean up those metal components just now, although they were not heavy, after being welded together, they weighed at least hundreds of catties, and the hundreds of catties of metal were as light as nothing in Liu Fei's hands......

PS: The eyes are finally slowly recovering, although there is some redness and swelling, but you can code words online, thank you brothers for your concern!
