After handing in the system, I became a national treasure by robbing supplies

But above the central command post, a gorgeous firework bloomed in the haze.

For a moment, everyone was attracted by the gorgeous fireworks.

Firecrackers and fireworks are the yearning of the people of Dachuan Kingdom for beauty.

They can no longer imagine such a life after the end.

But now, fireworks are blooming above them again.

This symbolizes hope that everything will pass.

Bang bang!

There were two more fireworks, blooming in the sky.

It was clearly broad daylight now, but the effect of the fireworks was not concealed at all.

It seems that the light of the fireworks itself is enough to cover the sunlight.

Everyone in the central base, as well as the surrounding defensive bases and garrison posts heard the sound, and they all looked up at the sky strangely, with tears in their eyes.

A mother Jiang held her four-year-old child in her arms, her voice choked with sobs.

"Ninny, look quickly, this is called fireworks, it looks good."

The child said in a childish voice, "It looks good."

The fireworks exploded in the air, obviously fleeting, but they felt that the speed of the fireworks dissipating was extremely slow, as if the scattered light spots were pressed by 0.5 times the speed.

Someone took a deep breath, but did not smell the saltpeter smell of firecrackers, but the surrounding air seemed to be getting fresher.

After this wave of zombies, all the plants on the continent were destroyed, and nature lost its balance. If there was no rich land that the system manifested, they would have died of lack of oxygen.

But now, the air is a little cleaner.

As if standing on the top of a mountain, breathing the most primitive air, the air that has not been polluted by urban industrialization.

"How do I feel...the air is fresh?"

"I also feel this way! Before, the air was cloudy and my rhinitis often broke out, but now, the impurities in the air seem to have been removed?"

"This feeling is really amazing! I have returned to our prairie!"

An old man suffering from illness suddenly sat up from the bed, took a deep breath, his originally decadent appearance seemed to have been injected with chicken blood.

He got out of bed tremblingly, and his son, who was guarding outside the door, hurried out when he heard the movement inside.

"Dad, your bones are too weak, don't get out of bed."

The old man coughed a few times suddenly, and a strange brilliance shot out from his cloudy and godless eyes.

"Air, the air suddenly became better!"

The man helped the old man out and looked up at the sky.

At this time, a beam of sunlight came down and poured on them.

The warm light gently caressed their skin.

All the people in the room came out.

After experiencing several catastrophes, the survivors who can survive now are all lucky.

A screen pops up from the chip on everyone's wrist.

On the screen is Wei Zheng.

"Everyone, don't panic. What you see now is the medium-sized air purifier brought back by the soldiers from another world. After the technical transformation of our relevant technicians, the air purification coverage has reached 200 million square kilometers. It can Cover our existing survivor base in Dachuan Country."

"Please pay tribute to our soldiers on the front lines, and for the next three months, everyone can enjoy unpolluted air."

All of a sudden, there were cheers everywhere.

"Haha! Air purification! Our country is really good!"

"Salute to the warriors!"

"Salute to the soldiers!"

"Thanks to them, they are carrying forward for us!"

The thick clouds were finally pushed away, and the dazzling sunlight shone on the ground.

Soon, people's skin felt a little tingling, and they quickly hid indoors.

This time the environmental damage was so serious, the ozone layer was destroyed, and the ultraviolet rays were too strong.

But not long after, the center released an instrument again, and an invisible protective barrier was released towards the sky, greatly weakening the ability of ultraviolet rays.

Luoxu was a little surprised, and stretched out her hand to the sun to feel the soft light.

The old professor at the side said: "This is a magnetic field optoelectronic technology. The country has been developing it for a long time, and now it has begun to bear fruit."

The old professor came forward and patted Luo Xu on the shoulder, "With your system, the country's science and technology are developing rapidly, and you are definitely our biggest contributor!"

Luo Xu just smiled slightly.

"It's all the result of everyone's hard work."

It was almost noon before Wei Zheng finished his other affairs and returned to his residence.

Before he could take off his military uniform, he asked Luo Xu to go to the study for a private chat.

Luo Xu told him the situation after the system improvement, and Wei Zheng's face was solemn.

"Can you take me to the third-level map now?"

Luoxu shook his head, "Once you enter, you can only pass the level or die."

Wei Zheng sighed, "It seems that our advantage is gone. I thought we could enter the system in advance to check the terrain, but now..."

This is only a level three map, will there be level four, level five and level six next?
No one can tell.

"Which of your personal attributes is most likely to be fully qualified now?"

Luo Xu said: "The scientific research technology is already 97, but the remaining three points can't be full, and I don't know why."

Wei Zheng frowned and paced back and forth.

"How about this, you rest for a few days, and I will arrange for you to go to the front line to follow the professor's actual operation and do scientific research."

Luo Xu sighed inwardly, "Uncle Wei, after the system upgrade, there is a mall."

A voice came from Wei Zheng's pager. He was holding the pager and was about to operate it, but when he heard Luo Xu's words, he suddenly looked up at her and turned off the pager.

"You didn't tell me last night."

At the end, he asked again: "What's in the mall?"

If Wei Zheng knew the specific things in the mall, I'm afraid he would try his best to get them.

Now that she had spoken, Luo Xu was silent for a moment, and said: "All, weapons, spaceships, spaceships, interstellar combat weapons..."

Just these few words, Wei Zheng was shocked.

"Can all the things bought in it be turned into reality?"

Luo Xu nodded.

spaceship……

Star Wars Weapons!

can become reality...

Then the whole earth can develop the aerospace industry.

Before the end of the world, their detection distance was very short, and even Mars did not fully understand it. With these technological bonuses, they will soon be able to build a defense line outside the earth and bring the entire earth's technology to full value.

Wei Zheng rubbed his hands excitedly, pacing on the spot.

"Great, great!"

"You have to know that opportunities and risks coexist. Since we already know the existence of these technologies and may use them for our own use, then we must master them and not wait for other forces in the universe to attack us."

"Actually, many years ago, we have discovered the traces left by aliens, the pyramids under the sea, and a string of undeciphered data left on Mount Everest... These are all evidence!"
