After a period of continuous experimentation, although I didn't understand the principle of the energy box that the alien took off, I figured out the energy output method of the energy box, which is the most ordinary electric energy, and it really looks like a battery box. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

The 10-kilogram individual energy box provides an energy output of 100 kWh, which can last up to 30 hours at maximum power when filled with 6 litres of water.

What's even more amazing is that the water is not consumed, just stop the power output, and the energy will start to recover slowly, and it will automatically recover about five percent per day, which is in principle the equivalent of a perpetual motion machine.

I don't know what the principle is, but I have a bold guess that when this water is placed there and does not extract energy, it should be able to absorb some special wave in the universe and gradually restore its energy, and what this energy is can only be said to be unknown. I don't know if the water in the real world can be used, but for the sake of insurance, it's better to fill this world with a dozen water back.

These days, we have been collecting good ion thrusters, violently removing those that have not been damaged from some downed alien vehicles, and storing hundreds, if all assembled, at least thousands of tons of heavy objects can be lifted into space.

After more than ten days of continuous attempts, it was really successfully connected to the right energy box, just because there was no power output control system, as soon as the thing was connected, the maximum power injection in minutes, there were often small accidents, but fortunately they were cautious and did not make any injuries.

After more than a dozen small accidents, I finally figured out the way to adjust the power output, and now I use manual adjustment for the time being, and then hire some professionals to do electronic automatic adjustment after I go back, and then ask someone to get a set of control system, maybe it can be controlled by a computer...... Anyway, if you have money, you are not afraid that you will not be able to hire someone to help!

These days, Anna is more like her professional assistant, helping herself with experiments every day, and more often than not, asking herself some strange questions, she is preparing material for future novels. Li Yunfei didn't hide too many things, and told her everything he could say.

……！

After nearly two months of aliens destroying the earth, they finally retreated in full force, and it seemed as if humanity had won the war, but in fact, who had won, smart people would understand at a glance.

The aliens have pumped a huge amount of seawater from the Earth, causing the sea level to drop by nearly 10 meters all over the world, and you can imagine how terrifying the amount of sea water is pumped.

As for the question of whether this group of aliens will hate the earthlings after so many deaths on Earth, this is really not.

Because those so-called aliens are just cyborg soldiers who come down the assembly line to fight cyborgs, they are not their real clansmen at all, and their clansmen are very expensive, of course, they will not fight with the earthlings.

It's just that this time the water grabbing is because of the fierce resistance of the earthlings, so the profit is not big, and the current earth has no great benefit for that group of real aliens, if it really forces this group of natives to be urgent, and the large-scale dropping of large-yield nuclear bombs is not good for everyone, so the robbery can be stopped.

Originally, some time ago, I thought that a new unknown element had been discovered, but that thing appeared from time to time, and I began to wonder if it was real.

It's not because this group of water polo natives deliberately made a false signal to deceive themselves, otherwise why were they wiped out so many times, and none of them came back? This was the real idea of the aliens, so in the end, the interest in the mysterious radiation source was greatly reduced, and in the end, it was not interested at all.

……

If the human world knows that it has killed a large number of aliens desperately, it is just a group of mining security biochemical people filmed by this group of aliens, which can only be regarded as a tool-like existence.

That must be quite uncomfortable in my heart, some things are still not known, I really think it is terrible, it is very desperate, it is rare to be confused.

Humanity has won the war, that is, it has successfully repelled the invaders, and everyone lives in a fairy tale woven by themselves, which is actually quite good, maybe a very few people have discovered this, but they have not said it.

Of course, this alien attack has also benefited mankind a lot, and in the future, space and astronautical technology will get a great leap forward. It's not just Li Yunfei who looks at the thermodynamic system, almost all countries have taken action, cleaning up the battlefield and picking up equipment, and everyone is very active.

……

"Mission complete, return in three minutes!" Li Yunfei, who was having a big meal, suddenly received a message, the task was completed so inexplicably, obviously there were still some aliens in the distance, it seemed that those aliens were abandoned by their organization.

“…… Anna, I'm leaving in three minutes! ”

"Ah, how can it be so fast? Haven't all those aliens been wiped out yet? ”

"Those are just stragglers, they should have been abandoned by their large army!"

"How can this be, those aliens are too bad, right?"

“…… Maybe the aliens we've been exterminating are just a bunch of war machines, not real aliens! ”

"Well, maybe you're right...... It's really sad that humanity has paid such a heavy price and is only dealing with a bunch of tools. ”

"This is a huge gap in technology, and it can only be filled with human lives, and there is no way to do it...... In fact, when your American troops attacked those areas in the Middle East, they also used countless lives to fill your aircraft and artillery. ”

“…… Lee, in fact, I have always been anti-war, and there are many people who are strongly opposed to war, and you can't blame me for those things! ”

"Of course, my team members are good people who protect world peace, how can I blame you."

"Lee, will you come to this world again in the future?"

"I don't know, probably not! So this time it might be goodbye......"

Before she finished speaking, Anna suddenly hugged Li Yunfei and kissed her, which made Li Yunfei stunned for a moment, and also hugged each other.

It's just a kiss goodbye, and there's no need to refuse, I thought that after more than a month of getting along, it was already a pure comrade-in-arms relationship, but I suddenly found that it was really not. After kissing for more than a minute, Anna let go of Li Yunfei.

"Now that we're even, I hope we can see you again one day!"

"Goodbye, then, Anna...... This DV will be returned to you, and this necklace will be given to you as a souvenir, of course, you can sell it when you are short of money to spend, and you should be able to exchange it for some money. Li Yunfei took out a very beautiful gemstone necklace and put it in her hand, Anna wanted to say something.

However, Li Yunfei couldn't hear it, only to see a seven-colored light flash from the center of his eyebrows, which quickly surrounded his entire body, and then the person also turned into a faint rainbow and disappeared.

“…… It turns out that myths are not all deceitful, sitting on the colorful light and walking on the colorful light...... Will you ever come back? Anna muttered to herself as she looked at the disappearing rainbow. The gemstone necklace in his hand is also carefully hidden, in case he really loses this chain when he sees him again, it will be too embarrassing.
