However, I saw a brilliant firework blooming in the haze in the sky above the central command post.

For a while, everyone was attracted by this brilliant fireworks.

Firecrackers and fireworks, these are the people's yearning for beauty.

After the end of the world, they could no longer imagine such a life.

But now, the fireworks are once again in the sky above them.

This symbolizes hope that everything will pass.

Bang bang!

Two more fireworks, blooming in the sky.

It was clear that it was broad daylight, but the effect of the fireworks was not concealed at all.

It was as if the glow of the fireworks itself was enough to block out the sun's rays.

The central base, as well as several defensive bases and garrisons around it, everyone heard this voice, and they all looked up at the sky in surprise, tears welling up in the corners of their eyes.

A four-year-old child, a mother, was held in her arms, and her voice was a little choked.

"Look, look at it, this is called fireworks, it's beautiful."

The child's voice was milky, "It's beautiful." ”

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

Someone took a deep breath, but they didn't smell the saltpeter smell of firecrackers, but the air around them seemed to be fresher.

After this zombie wave, all the plants on the continent were destroyed, nature was out of balance, and if there was no fertile land that was systematically manifested, they would have died due to lack of oxygen.

But now, the air is a little fresher.

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

"How do I feel...... Fresh air? ”

"I feel that way too! Before, the air was turbid, and I often had rhinitis, but now, the impurities in the air seem to have been removed? ”

"It's an amazing feeling! I'm back in our prairie! ”

An old man who was riddled with illness sat up from the bed abruptly, took a deep breath, and looked like he had been beaten with chicken blood.

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

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

The old man coughed violently, and a strange brilliance burst out of his cloudy eyes.

"Air, air suddenly got better!"

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

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

The warm light gently caresses their skin.

The people in the room all came out.

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

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

On the screen is Wei Zheng.

"Don't panic, what you see now is the embodiment brought back by the warriors from the other world, the medium-sized air purifier, after the technical transformation of our relevant technicians, the air purification coverage area has reached two million square kilometers, which can cover the existing survivor base of our Dachuan country."

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

For a while, cheers erupted.

"Haha! Air Purification! Our country is really good! ”

"Salute to the warriors!"

"Salute to the warriors!"

"Thank them for carrying the weight for us!"

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

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

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

However, it didn't take long for the center to release a device again, and an invisible protective barrier was released into the sky, greatly weakening the ability of ultraviolet rays.

Luo Su was a little surprised, and reached out into the sunlight to feel the soft light.

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

The old professor stepped forward and patted Luo Xu on the shoulder, "With your system, now that the country's science and technology are developing rapidly, you are definitely our greatest hero!" ”

Luo Su just smiled lightly.

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

When it was almost noon, Wei Zheng finished dealing with other things and returned to his residence.

Before he had time to take off his military uniform, he called Luo Su to go to the study to talk alone.

Luo Su told him about the situation after the system was improved, and Wei Zheng's face was solemn.

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

Luo Su shook his head, "Once you enter, you can only clear the customs or die." ”

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

This is just a three-level map, will there be four, five, and six levels next?

No one can say.

"Which of your personal attributes is most likely to reach full right now?"

Luo Xu said: "Scientific research and technology, it's 97, but the remaining three points can't be full, and I don't know why." ”

Wei Zheng frowned and paced in place.

"In this way, you rest for a few days first, and I will arrange for you to go to the front line to follow the professor to do scientific research."

Luo Xu sighed in his heart, "Uncle Wei, after the system was upgraded, a shopping mall also appeared. ”

A voice came from Wei Zheng's pager, and he was about to operate it with the pager, but when he heard Luoxu's words, he suddenly looked up at her and turned off the call directly.

"You didn't say that last night."

At the end, he said, "What's in the mall?" ”

If Wei Zheng knew the specific things in the mall, I am afraid, he would go to great lengths to get them.

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

Just this few words, Wei Zheng was shocked.

"What you buy in it, can be turned into reality?"

Luo Su nodded.

Spaceship......

Interstellar Combat Weapons!

can be turned into reality......

Then the whole earth can develop the space industry.

Before the end of the world, their detection range was very short, and even Mars did not fully understand it, and with these technological bonuses, they would soon be able to build a line of defense outside the earth, pulling the technology of the entire earth to full value.

Wei Zheng rubbed his hands together excitedly and paced in place.

"Great, great!"

"You must know that opportunities and risks coexist, and since we already know the existence of these technologies, and it is possible to use them for our own use, then we must master them, and we can't wait for other forces in the universe to make a move against us."

"In fact, many years ago, we have found traces left by aliens, underwater pyramids, and a string of undeciphered data left on Mount Everest...... It's all evidence! ”
