Shen Feng did not let the last nanomachines disintegrate on their own, but kept them.

There is nothing wrong with technology itself, only human greed and desire.

On the current earth, human civilization is like a small flame in the strong wind, which may be extinguished at any time.

The existence of nanomachinery clusters is extremely important to human civilization.

After all, if you want to restore the glory of human civilization, it is not enough to rely on the factories left by Shen Feng. It also requires talents, time, and inheritance from generation to generation.

Before that, human beings need strong power to protect themselves from extinction.

Otherwise, a global hurricane or other disaster may destroy the remaining human civilization.

Of course, Shen Feng did not hand over the administrator rights, but gave a group of Salvation Army soldiers super-high-level auxiliary administrator rights.

Although they can control the gray tide, they cannot modify the basic protocol of the gray tide.

Shen Feng placed restrictions on these nanomachinery clusters in the source code.

The first is that they cannot attack humans, and the second is that the number of all nanomechanical bugs has an upper limit. Once this upper limit is reached, they will begin to naturally decline.

At the same time, nanomechanical bugs can attack each other to eliminate some individuals that are damaged out of control.

In this way, gray tide disasters will never happen again.

After all, the number of nanomechanical bugs that can exist in this world has been limited, and their combined size is only the size of a mountain.

Those Salvation Army soldiers with super-high-level auxiliary administrator privileges have the same ability to control the nanomachinery cluster.

This is also a check and balance.

After all, the human heart is the most unpredictable.

Even those who were willing to sacrifice their lives to save human civilization may change in the face of power and desire.

Shen Feng's arrangement also received approval and support from all the Salvation Army soldiers.

They also understand that even they may lose their original intention, and this decision now is the wisest.

After making these arrangements, Shen Feng said to the "Real Doomsday Game" bracelet:

"The cause of the gray tide outbreak has been found, and the gray tide has been completely controlled. The latest iteration of the gray tide sample has been obtained, and structural damage and assimilation have been avoided. Apply to submit the gray tide apocalyptic mission and receive the mission reward."

A few lines of words flashed on the screen of the bracelet:

"Please place the latest iteration of gray tide samples in a sealed container."

Looking at the vast land around him, Shen Feng couldn't help but roll his eyes.

Where can I find an airtight container for you?

After thinking about it carefully, he dug a hole in the ground, put a fist-sized nanomachine cluster sample into it, and sealed the hole with mud.

This should be regarded as the simplest sealed container.

Soon, a line of words flashed on the bracelet screen again:

"Start mission evaluation: mission completion, 95%. Start award distribution: Reward one, an anti-viral serum. Reward two, permission to use the space channel once, and can summon the original apocalyptic world to the mission world, time limit Depends on the upper limit of energy. Reward 3: You can freely choose beings in the mission world to bring back to the original doomsday world, depending on the upper limit of energy transmission. Reward 4: Use the space channel once, and you can summon beings in the mission world to go to the original doomsday world. The time limit depends on It depends on the energy limit.”

Shen Feng couldn't help but raise his eyebrows.

The reward this time is quite generous.

However, he still did not complete the task 100%.

It is probably related to Arthur Seldon's sudden rampage and destruction of the world.

Shen Feng was thinking with his toes at this time and he could guess that behind this, in addition to Arthur Seldon's inner distortion due to the death of his relatives and his own desires, there must also be the shadow of the Whisperer behind it.

Of course, he had not found any information about this before.

But I guess the Whisperers wouldn't miss this opportunity.

The other two space channel usage rights are bidirectional, which is of great significance to Shen Feng.

Now he has two permissions from the mission world to the original world, and one permission from the original world to the mission world.

At special moments, this kind of authority will play an extremely important role.

As for the anti-viral serum, it's a bit strange.

However, Shen Feng has gone through so many experiences and naturally understands that the more inconspicuous something the game system gives, the more likely it is to be very awesome.

For example, "Principles of Nanomachines" and "Basic Principles of Hypnosis".

He did not apply to receive this serum for the time being, but kept it.

After all, this thing shouldn't be used now, but I don't know under what circumstances it will be used.

As for the reward of bringing the existence of the mission world back to the original world, it is naturally even simpler.

Shen Feng chose a part of the nanomachinery cluster without thinking.

Apart from this thing, there really isn't much that can be done in this world.

He was honest and unceremonious and directly selected a gray tide the size of a room, but was told that it exceeded the energy limit. In the end, he reduced it repeatedly and was able to get rid of a gray tide the size of a car.

But that's enough.

After all, this thing can continue to eat and grow, and it is possible to swallow the entire earth.

As for the quantum backpack, he packed several paintings.

Paintings and paintings taken from the museum where Arthur Seldon kept them.

"Mona Lisa", "Sunflowers", "Along the River During the Qingming Festival", "Walking on the Chariot", etc. are all top-notch masterpieces in the world.

Of course, there are also these paintings in the original world. They are all authentic works, but the world is different.

After doing this, Shen Feng looked around under the gray tide and looked at the reborn world again, wanting to make sure there was nothing missing.

"Have you forgotten my dear?" Jingwei said angrily.

Shen Feng was stunned: "What little boy?"

"That's the Dongfeng strategic nuclear missile launch vehicle! Men are indeed heartless and heartless men. They forget about it in the blink of an eye after using it!" Jingwei snorted coldly.

Shen Feng couldn't help but slap his forehead, he had indeed forgotten about the launch vehicle.

Even though the nuclear bomb was fired, the car is still there!

But how did your little boy get his name?

"Where's the car?" Shen Feng asked quickly.

"It has been forcibly sent back a long time ago! The energy reaction is too great, I can only stay for a while, I have let it go back through the space channel on its own." Jingwei said again, obviously very dissatisfied with Shen Feng's neglect of the little boy.

After all, although the on-board computer is a low-level artificial intelligence, it is still artificial intelligence!

Your attitude towards artificial intelligence is not correct!

"Just go back, let's go back too." Shen Feng couldn't help but feel a little confused at this time. He didn't understand why Jingwei was upset, but after all, the advanced artificial intelligence had its own personality template, so it was okay to lose his temper.

At that moment, after saying goodbye to all the Salvation Army soldiers present, Shen Feng ordered the bracelet:

"The mission has been completed, please return to the original world!"

As soon as he finished speaking, under the reluctant gazes of the Salvation Army soldiers, Shen Feng disappeared instantly, leaving only a pair of footprints and the same gray tide as the hill.

Everyone stepped forward one after another, looking at Shen Feng's footprints and the huge gray tide in silence.

After experiencing countless hardships, the world was finally saved.

It's a pity that the savior is no longer here.

After a while, Li Tongchen looked at the comrades around him with firm eyes and said loudly:

"Gentlemen, the savior has said that we are our own saviors! This world needs our salvation! I hope that when the savior needs us, we can also give him enough support! Let's get started!"

With that said, he walked towards Gray Tide.

A huge cluster of nanomachines immediately emerged from the gray tide, wrapping Li Tongchen's body and transforming into a giant.

Immediately afterwards, other Salvation Army soldiers stepped forward to receive their own share of the nanomachinery cluster.

They will rush to all parts of the world with the gray tide they control, to rescue and gather those survivors, and once again ignite the torch of human civilization.

This fire is huge, blooming and falling everywhere in the world, and will eventually illuminate this planet that was once plunged into darkness.

…

The familiar feeling of darkness and dizziness came, and Shen Feng suddenly opened his eyes.

Warm lighting, carpets, big beds, mirrors, and various furnishings in the hotel room.

He has returned to the hotel room again.

There was even a half-drunk Coke on the table in front of him.

It's still the moment he just left.

But after experiencing everything at the end of the Gray Tide, many things have become different.

Shen Feng shook his head, letting his memory return to the time when he was at the end of the Gray Tide, then leaned back, lay on the soft bed, and let out a long sigh of relief.
To be continued...
