Shen Feng did not let the last nanomechanical cluster disintegrate on its own, but left them behind.

There is nothing wrong with technology per se, it is only human greed and lust that is at fault.

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

The existence of nanomechanical clusters is extremely important for 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, you also need talents, time, and the inheritance from generation to generation.

Until then, humanity needs strong forces to protect itself from extinction.

Otherwise, a global typhoon, or other disasters, may destroy the remnants of human civilization.

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

While they were able to contain Grey Tide, they were unable to modify Grey Tide's base protocol.

Shen Feng restricts these nanomechanical clusters in the source code.

The first is that they can't attack humans, and the second is that there is an upper limit to the number of all nanorobotic bugs, and once this upper limit is reached, they will begin to die naturally.

At the same time, nanorobotic worms can attack each other to remove some of the uncontrolled damaged individuals.

In this way, the gray tide disaster will never happen again.

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

The Salvation Army fighters with super-high-level auxiliary administrator privileges have the same ability to control the nanomechanical swarm.

It's also a check and balance.

After all, people's hearts are the most unpredictable.

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

Shen Feng's arrangement was also endorsed and supported by a group of Salvation Army soldiers.

They also know that even they may lose their hearts, and that this decision is the wisest thing to do.

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

"The cause of the outbreak of the Gray Tide has been found, and the Gray Tide has been completely controlled, and the latest iteration of the Gray Tide sample has been obtained, structural damage and assimilation have been avoided, and the Gray Tide Apocalyptic Quest has been submitted to receive the task reward."

A few lines flashed on the bracelet screen:

"Please place the latest iteration of the Grey Tide sample in an airtight container."

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

Where am I going to find you an airtight container?

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

This is probably the most rudimentary airtight container.

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

"Start task assessment: task completion, 95 percent. Start reward distribution: reward one, one antiviral serum. Reward 2: The space channel can be used once, and the original apocalyptic world can be summoned to the mission world, and the time limit depends on the upper limit of energy. Reward 3: You can freely choose the existence of the quest world and bring it back to the original apocalyptic world, depending on the upper limit of energy transmission. Reward 4: The space channel can be used once, and the mission world can be summoned to the original apocalyptic world, and the time limit depends on the upper limit of energy. ”

Shen Feng couldn't help but raise his eyebrows.

This time, the reward is quite generous.

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

It is estimated that it is related to Arthur Shelton's sudden violent demise.

Shen Feng could also think of it with his toes at this time, in addition to Arthur Shelton's inner distortion and perversion due to the death of his relatives and his own desires, there must be the shadow of a whisperer behind him.

Of course, he hadn't found this information before.

But those who want to whisper will not let go of this opportunity.

The access to the other two space channels is considered two-way, which is of great significance to Shen Feng.

Now he has the permission to go to the original world twice, and the original world to the mission world once.

This kind of authority can be extremely important in special moments.

As for what kind of antiviral serum it is, it's a little strange.

However, after so many times of experience, Shen Feng naturally understands that the more inconspicuous the things given by the game system sound, the more likely it is to be very awesome.

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

He did not apply for this serum for the time being, but deposited it.

After all, I shouldn't need it now, but I don't know under what circumstances.

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

Without hesitation, Shen Feng chose a part of the nanomachinery cluster.

There really isn't much else in this world that can be used other than this thing.

He was honest and unkind, and directly selected a room-sized gray tide, but was told that it exceeded the upper limit of energy, and finally reduced it again and again, and it was almost the size of a car to take away the gray tide.

But that's enough.

After all, this thing can continue to devour and grow, and it is possible to swallow the entire earth if you want to.

As for the quantum backpack, he loaded a few paintings.

Paintings and calligraphy taken from the museum that Arthur Shelton kept.

"Mona Lisa", "Sunflowers", "Qingming Riverside Picture", "Walking Diagram" and so on, all of which are the world's top boutiques.

Of course, there are also these paintings in the original world, and everyone is genuine, but the world is different.

After doing this, Shen Feng looked under the gray tide and took another look at this reborn world, wanting to make sure that there was anything missing.

"Have you forgotten your little girl?" Jingwei said angrily.

Shen Feng was stunned: "What little girl?" ”

"It's the Dongfeng strategic nuclear missile launcher! Men are really negative men with no conscience, and they forget it in a blink of an eye after using it! Jingwei snorted coldly.

Shen Feng couldn't help but pat his head, he really forgot about the launch vehicle.

Although the nuclear bomb has been fired, the car is still there!

But how did you come up with your little boy's name?

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

"I was forcibly repatriated a long time ago! The energy reaction is too great to stay for a while, and I've let it go back from the spatial channel on its own. Jingwei said again, obviously very dissatisfied with Shen Feng's snubbing of the little girl.

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

You don't have a good attitude towards artificial intelligence!

"Just go back, let's go back too." Shen Feng couldn't help but be a little confused at this time, and didn't understand why Jingwei was unhappy, but after all, advanced artificial intelligence has its own personality template, and it's nothing to lose a little temper.

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

"Mission completed, request to return to the original world!"

As soon as the words fell, under the reluctant gaze of the Salvation Army soldiers, Shen Feng disappeared in an instant, leaving only a pair of footprints, the same gray tide as the hill.

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

After countless tribulations, the world is finally saved.

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

After a while, Li Tongchen looked at his comrades-in-arms with resolute eyes, and said loudly:

"Gentlemen, the Savior has said that we are our own Saviors! This world needs our salvation! We hope that when the Savior needs us, we will also give him enough support! Let's go! ”

As he spoke, he walked towards the gray tide.

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

Immediately afterward, the other Salvation Army soldiers stepped forward one after another to claim their share of the nanomechanical cluster.

They will travel around the world with the gray tide under their control to rescue and rally those who survive, and once again light the torch of human civilization.

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

……

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

Warm lighting, carpets, large beds, mirrors, all kinds of furnishings in the hotel rooms.

He had returned to his hotel room.

On the table in front of him, there was even a half-drunk Coke.

Still the moment he just left.

It's just that after experiencing everything in the apocalyptic world of the gray tide, many things have become different again.

Shen Feng shook his head, letting his memory go back to the time point when he went to the end of the gray tide, and then leaned back, lying on the soft bed, and let out a long sigh of relief.

Comfortable.

This is the life of man.

Eating and resting in the apocalyptic world of the gray tide is simply to satisfy the most basic needs.

There was a rumbling in his stomach, and now he suddenly wanted to eat Chinese food.

Especially dumplings.

Preferably half leek egg filling, half carrot and mutton filling.

The mutton dumplings must have a meatball and a dumpling, which is called fragrant.

Then dip it in old vinegar and tsk......

Shen Feng thought that his saliva was about to flow out, and he was about to start directly connecting to the wifi to start ordering.

At this time, in the center of the room, there was a silver-gray metal mass, which was the nanomechanical cluster he had brought back.

Shen Feng beckoned, and the gray tide rushed to the side of the bed like a big dog, waiting for his order.

Shen Feng stretched out his hand to touch the gray tide while looking for a suitable restaurant nearby.

At this moment, there was a sudden sound of messy and slight footsteps outside the door.

Shen Feng couldn't help frowning, judging from the shaking of the ground, there were at least dozens of people coming over together, and there was still a load on them.

Although ordinary people can't hear it, it is difficult to hide it from his ears, after all, Gray Tide also has a huge number of sensors.

The men stopped when they walked outside the room he was in.

And they keep gathering outside the door.

Then there was a knock on the door:

Knock knock.

"Hello sir, room service."
