But I saw a gorgeous firework blooming in the haze above the central command post.

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

Firecrackers and fireworks are the people of Dachuan Country’s longing 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!

Two more fireworks bloomed in the sky.

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

It was as if the light of the fireworks itself was enough to cover up the sun's rays.

"I feel the same way! Before, the air was turbid and I often suffered from rhinitis. But now, the impurities in the air seem to have been removed?"

Soon, people's skin felt stinging and they hurriedly hid indoors.

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

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

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

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

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

The old man coughed violently several times, and a strange light burst out from his dull and dull eyes.

All can be turned into reality...

"Salute to the soldiers!"

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

Wei Zheng frowned and paced in place.

"Dad, your body is too weak, don't get out of bed."

Luo Xu told him about the improved system, and Wei Zheng looked solemn.

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

"Nanny, look, these are called fireworks, aren't they beautiful?"

"Let's do it this way. You can rest for a few days and I'll arrange for you to go to the front line and follow the professor's hands-on approach to scientific research."

Finally, he asked: "What is in the mall?"

Luo Xu shook his head, "Once you enter, you can only clear the level or die."

Luo Xu just smiled lightly.

Then can the entire earth develop aerospace industry?

An old man who was suffering from illness suddenly sat up from the bed and took a deep breath. He looked decadent as if he had been injected with chicken blood.

After this zombie wave, all the plants on the continent were destroyed, and nature lost its balance. Without the fertile land embodied by the system, they would have died of lack of oxygen long ago.

It's like standing on the top of a mountain, breathing the most primitive air, air that has not been polluted by urban industrialization.

spaceship……

"Everything you buy there can be turned into reality?"

Luo Xu sighed inwardly, "Uncle Wei, a mall has appeared after the system upgrade."

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

Everyone in the central base, as well as several surrounding defense bases and garrison stations, heard this sound. They all looked up to the sky with tears in their eyes.

For a time, cheers broke out from all over.

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

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

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

Fireworks exploded in the air, obviously fleeting, but they felt that the fireworks dissipated extremely slowly, as if these scattered light spots were accelerated by 0.5 times.

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

All the people in the room came out.

It was almost noon when Wei Zheng finished handling other matters and returned to his residence.

Interstellar combat weapon!

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

"This feeling is really amazing! I'm back on our prairie!"

The warm and genial light caressed their skin softly.

"Don't panic, everyone. What you are seeing now is the medium-sized air purifier that the soldiers brought back from another world. After the technical transformation of our relevant technicians, the air purification coverage area has reached two million square kilometers.

It can cover our existing survivor base in Okawa Country."

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

"The air, the air suddenly became better!"

Luo Xu was a little surprised and stretched out her hand under the sun to feel the soft light.

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

"Can you take me to the level 3 map now?"

"Of your personal attributes, which one is most likely to be perfect now?"

"You didn't say anything last night."

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

"Thank you to them for carrying the burden for us!"

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

Just these few words shocked Wei Zheng.

Luoxu nodded.

He got out of bed tremblingly, and his son who was guarding the door quickly came out when he heard the noise inside.

But now, the air is a little fresher.

"Please pay tribute to our soldiers fighting on the front line. In the next three months, everyone can enjoy unpolluted air."

On the screen is Wei Zheng.

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

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

This is only a level 3 map. Will there be levels 4, 5 and 6 next?

No one can tell for sure.

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

"Salute to the warriors!"

At this time, a ray of sunlight shone down and poured on them.

Before the end of the world, their detection range was very short, and even Mars had not fully understood it. With these technological bonuses, they would 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 and paced in place.

"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 purposes, we must master them and cannot wait for other forces in the universe to take action against us."
