In the last days, although there are birds of prey, human beings can still want to control the air. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

If nothing else, the main thing is to be fast. In addition, having air supremacy gives you an absolute advantage in war.

At the very beginning of this world, when the world became the end of the world, humans still had a large number of warplanes in their hands. Similar to flying machines, they have a wide variety of weapon systems. At that time, as human beings continued to search for new supplies, military bases were cleared out one by one, and people got a lot of fighters.

But it is precisely because of the presence of birds of prey in this apocalyptic world that the number of those fighters is decreasing day by day.

In the last days, a large number of manufacturing plants were destroyed, and coupled with the restrictions on manufacturing residues, it was difficult for people to build warplanes after entering the last days.

In this case, basically one aircraft is damaged, and one aircraft is missing. Twenty years have passed since the end of the world, and there are now very few fighters that can fight normally. Wang Haoyu has been in the end of the world for so long, and he has not even seen it once.

And the north is more developed, he doesn't know if there are fighters in those bases here, which is why Wang Haoyu is in such a hurry to upgrade the system. Compared to weapons on the ground, it is the air that is the real threat.

Sure enough, when he checked the aviation system, Wang Haoyu really saw a fighter that could be exchanged.

This black fighter plane has a strange shape, not like a real-world aircraft, but like a relatively narrow pyramid as a whole.

After reading the introduction, Wang Haoyu knew that this fighter could carry four ground-to-ground missiles. Anti-aircraft weapons are not missiles, but laser cannons.

Although it can carry fewer weapons, the fighter itself is not very large. But what made Wang Haoyu's eyes light up was the flight speed of this fighter.

The flight speed of the fighter plane reached 1,000 kilometers per hour, and it was charged by energy value, but the energy consumption was too high, and it actually required 50 energy points per kilometer.

Not only does it cost money to recharge, but so do the four missiles. The price of 10,000 energy points is not low.

Just imagine, if Wang Haoyu were to attack a target five hundred kilometers away, the recharge alone would reach 50,000 energy points. Coupled with the price of four missiles, a round trip will cost nearly 100,000 energy points.

But after thinking about it, Wang Haoyu still felt that it was not very expensive. Now a strategic missile in the system costs 100,000 energy points, and the distance is limited, with a range of only 10 kilometers. As long as the fighter has energy, it can fly infinitely, and in comparison, the fighter is more cost-effective.

Seeing this fighter, Wang Haoyu had the idea of driving it around the world. But soon, that idea was dispelled.

Despite the fact that the flight speed of 1000 km/h is not slow, the average Raptor cannot catch up with it. But what Wang Haoyu is really worried about is not birds of prey, but humans.

Birds of prey are capable of finding targets within a certain range, while humans are different. With all kinds of detection systems, they are likely to find his fighters from dozens of kilometers away.

For a flight speed of a thousand kilometers per hour, tens of kilometers may be just three or two minutes. But that's enough time for the other side to lock it on with some weapons. Wang Haoyu believes that in this northern base, his fighter planes may not be able to avoid being attacked when they fly at will, let alone abroad.

But this does not mean that this fighter is useless, on the contrary, it is still very useful. It's just that no weapon is absolutely safe, there is no most powerful weapon in the world, only more and more powerful.

The price of the fighter is really not low, and it has reached 10 million energy points.

At present, after Wang Haoyu upgraded the main system, all the belongings on his body were only more than 15 million magic crystals. This number may seem small now, but when we first came to the end times, it would be astronomical. You must know that when Wang Haoyu first earned 300 magic crystals, it took three days to kill wolves.

After all the systems were upgraded to level 7, Wang Haoyu checked the energy value required to upgrade to level 8.

The price of Gene Enhancement Level 8 was as Wang Haoyu expected, reaching 100 million energy points. Seeing that string of numbers, Wang Haoyu couldn't help but have a headache.

Each of the three individual items, such as the weapon system, requires 50 million energy points, which is not as much as genetic enhancement, but the combined price is exceeded.

In the end, if the main system wants to be upgraded to level 8, it also needs 150 million energy points.

In this way, if you want to upgrade all systems to level 8, you need 400 million energy points.

After upgrading all the way before, Wang Haoyu did not feel any difficulty. Only now did he realize that the number was too large.

How many mutant beasts and zombies there are in the entire Tianhua Kingdom, Wang Haoyu doesn't know. But he knew that if he only hunted mutant beasts and zombies, he didn't know how long it would take to get the money together.

Fortunately, there are crystal ores in the last days, and he can also draw energy points from some energy bodies. In this way, there are more channels to get energy points. But just that, it's enough for him to save for a while.

It is worth mentioning that in the current potion column of the exchange system, you can exchange for level 5 enhancement potions. The price is not as high as Wang Haoyu imagined, as long as 5 million energy points. For this price, Wang Haoyu is still acceptable.

In fact, he had long had the idea of taking the enhancement potion to his relatives in the real world, and the reason why Wang Haoyu would rather be questioned than treat Na Ge Lao in the first place was that he had selfish intentions, that is, he wanted to try whether the repair potion was good for people in the real world.

But then Wang Haoyu dispelled the idea of using strengthening potions for his relatives, after all, he can control himself alone, and if the people around him accidentally leak out, they are not normal physique, and they may be arrested as guinea pigs.

If that really happens, Wang Haoyu is not helping them, but harming them. If the people around him are in need, he can take out a repair potion to use for them, instead of strengthening the potion.

"Boss!"

Now that a short time has passed since the upgrade, everyone in the base has awakened. At this time, Wang Jun came to Wang Haoyu's side and spoke.

"Boss, the second task you gave me is complete." Looking at Wang Haoyu, Wang Jun said: "Although it has not reached perfection, it is completely enough according to the background of the kind of technology you envisioned." ”

"Great! Grab it and give me a copy! ”

Hearing the news, Wang Haoyu showed a happy expression.
