I have to say that human beings are really a very tenacious race.

In the case of lack of water, lack of food, poor living environment, surrounded by all kinds of monsters, and these monsters hunted down humans, the human beings outside Huaxia still persevered for a year before they were completely exterminated.

Outside of China, when the last human being was exterminated, it was a dry and cold winter.

There are just three days to go, and it's time for the New Year.

The system carried by Wang Hao suddenly sounded, prompting Wang Hao that the unification of all mankind in the Great Wilderness had succeeded, and the system had been upgraded to a four-level system.

Hearing this news, Wang Hao's first reaction was not to check what new features were available after the system upgrade.

Instead, he climbed the wall of Hwaseong City, stood on it, braved the cold wind, and looked into the distance for a long time without saying a word.

Wang Hao is not a fool, the system can be upgraded to level four, which means that Ming, except for Huaxia, all the human beings in all other places are extinct.

Three days later, at the annual meeting, Wang Hao announced that Huaxia would enter a new era, and in order to commemorate this, this day will be positioned as a day of the new era.

The time of the year and the day in the future will be based on today.

The clansmen did not have any objections to Wang Hao's decision. After all, in their opinion, although the name has been changed, the time will not be reduced, not to mention that this is Wang Hao's decision, so naturally no one will object.

However, only Wang Hao knows that from now on, Huaxia will be completely different.

When the system was upgraded to level four, when Wang Hao checked the downloadable things of the system for the first time, the first thing he looked at was naturally the weapon system he was most concerned about.

At a glance, Wang Hao immediately felt that his spring was coming.

In the four-level system, not to mention anything else, the weapon system alone has comprehensively surpassed the level on the earth.

The nuclear bombs and hydrogen bombs that are shouted every day on the earth are just the most ordinary weapons in the system space.

Among the weapons that can be downloaded from the four-level system, there are countless superweapons that surpass nuclear weapons in different aspects.

For example, in terms of the degree of destruction, a super laser weapon capable of knocking the moon through in an instant.

A super-explosive bomb that explodes and can destroy a planet in an instant.

You can use the rules of nature to form a super typhoon that is more powerful than a super typhoon in a short period of time, and there are basically no super typhoons on the earth that have not appeared in the past 20.

In terms of the degree of harm, it is a virus that can infect all living things in a short period of time, and it is basically incurable, and can be transmitted through various ways such as air, water, and contact.

It can change human genes and mutate humans into the elixir of the zombies in the movie.

Create a radiation area that will be a radiation weapon that has been in radiation for tens of thousands of years within a certain range.

If it's strategic.

The aircraft carrier or something is simply weak.

Those spaceships are large enough to provide living space for tens of millions of people to travel in the universe.

A portal that can create spatial wormholes and transfer large numbers of dead objects from one place to another.

Moreover, the four-level system can not only download these large-scale weapons, but also surpass Wang Hao's imagination in terms of individual weapons.

For example, the combat armor of individual soldiers.

When worn, it can give humans superhuman skills.

As long as you learn to control, even if a child puts on combat armor, you can rely on the armor to fight against powerful third-level creatures.

And some individual weapons that can be used to shoot are also very powerful.

The individual hand-held guns that can be downloaded from the four-level system are as powerful as the main guns of the current tanks in Huaxia.

The sniper rifle in the four-level system can not only fire bullets of various types and functions, but also in terms of strength, it is comparable to the best armor-piercing bullet in Huaxia at present.

As for the heavy firepower of those shoulder resistance, they are even stronger than the most powerful missiles in China at present.

In addition to these, those that make Wang Hao dazzling all kinds of tanks, combat vehicles, and fighters.

Either way, it's basically only in science fiction stories.

At the beginning, Wang Hao saw this, which made him feel excited.

But after watching it for a long time, Wang Hao had a feeling of fear.

If nothing else, the weapons of the fourth-level system are really terrifying.

At every turn, there is the possibility of destroying the entire wilderness, and then destroying mankind.

With such powerful weapons, Wang Hao didn't know, whether it was good or bad to download them.

You know, people's hearts are unpredictable.

These terrible weapons in the fourth-level system, even if Wang Hao is in his own hands, he is afraid that these weapons will be hot.

If one day on a whim, he throws seventeen or eighteen hydrogen bombs at the Great Wilderness, and when the time comes, the entire Great Wilderness will be sunk.

Therefore, if these weapons are downloaded and handed over to others, no matter who they teach them, Wang Hao is a little uneasy.

After all, these weapons are powerful enough to destroy the entire world, and no one dares to guarantee that there will be no accidents.

After hesitating again and again, Wang Hao decided not to worry about the weapon for the time being, he checked it, after the system was upgraded to level four, there were some new functions.

In the past, every time the system was upgraded, it would prompt what conditions needed to be met for the next upgrade.

But this time, it seems that after that, the conditions for upgrading the system to a fifth-level system have not been given.

In other words, although there is a five-level system, Wang Hao has no way to upgrade the five-level system.

But it's okay, the fourth-level system is so terrifying, and if the fifth-level system is upgraded, it will be too terrifying.

Secondly, after the system was upgraded to a four-level system, the number of downloads per day increased to ten.

In other words, Wang Hao can download ten new technologies every day from now on.

And the number of productions per day, as much as Wang Hao unexpectedly, has increased from 1,000 to 10,000.

Moreover, what makes Wang Hao most pleased is that the storage limit of the system space has almost become unlimited.

Moreover, all kinds of things that were stored in the system space by Wang Hao as raw materials can be taken out by now.

It's no longer the same as before, you can only save it, you can't take it.

In the past, Wang Hao stored all kinds of residues in the system space have accumulated a lot of them.

Wang Hao was worried that those residues were encroaching on the space, and now that he could take it out, Wang Hao immediately found a dry lake and poured it out.

At this time, the debris poured out was enough to level a huge lake.

The increase in the number of downloads and productions is just the most basic functional enhancement of the system, which is expected by Wang Hao.

But continuing to look down, a look of surprise suddenly appeared on Wang Hao's face.
