The materials on this shelf are all self-help plans that humans in the old days had implemented not long after the copies appeared.

Jiang Bei pulled out a document that read "A Rough Summary of the Old Times Plan".

The shelves are full of information, and he has read them one by one, and he may not have finished reading them for several days, but fortunately there is an empathetic summary here. It's a little rough, but you can get a general idea after reading it.

Jiang Bei thought as he began to flip through this slightly crude history of human struggle.

In the process of confronting the dungeon, the first plan of mankind is the "Network Breaking Project"

At that time, the number of copies was rapidly increasing and threatening to spread to the whole world, and these copies were like a large net that trapped humanity in it.

So the net-breaking plan began to be implemented.

The human hierarchy selects three pilot areas with dense replicas and launches three nuclear weapons to strike at these three areas, trying to destroy the replicas from the outside.

But failed.

As soon as these three nuclear weapons came into contact with the copy, they were devoured and disappeared, and they were not blown up.

Jiang Bei's gaze stopped at the word "nuclear weapon" for a moment.

"I heard that human technology in the old era was very advanced, and the weapon mentioned above can destroy an entire city with one piece, and if this thing is thrown at our Ark base, the base will definitely be blown up, but unfortunately it is useless for the dungeon." Why did he look at the information in Jiang Bei's hand about the net-breaking plan.

The dungeon does devour things from the outside world and make them disappear, and the original landforms in the area will be covered by the new things in the dungeon after clearing the dungeon.

Jiang Bei continued to look down.

After the failure of the net-breaking plan, the humans tried to break it from the inside of the dungeon.

Someone wants to drive a tank into a dungeon, but driving this thing is like driving in, and the car will disappear when you get in.

The only thing you can leave behind after entering the dungeon is a small belonging.

So people brought various small arms that could be brought into the dungeon and tried to damage the ghosts inside, but they also failed.

In the past few years when humans in the old era tried to fight against the dungeon, there was a new discovery at the top.

Finding that the number of copies near the poles was very small, they decided to embark on the "Great Migration", moving the remaining humans to the north and south poles, away from the danger zone.

"North and South Pole ......"

Here again comes a familiar word.

"Why," Ebetsu looked up suddenly, "Is there a map left over from the old era in the database?"

"There should be." He nodded, "I see that the bookshelf over there is labeled with a map of the old world, I didn't have a chance to look at it before, but now I can."

As he spoke, he ran to a bookshelf, quickly searched for it, reached for a file bag, and ran back.

I saw him reach out and open the file bag and take out a folded coated paper.

"Seems to be a bit big." He carefully spread out the folded paper, and then a world map almost two meters long appeared in front of Jiang Bei.

It was a map he knew best.

There was a map on the head of the bed in his grandfather's house.

The map in front of him was exactly the same as the world map of his previous world.

Ebetsu studied geography before dropping out of school, and his geography teacher forced them to draw maps of famous mountains and rivers on various continents every day.

He looked at the map from his memory, and saw that every river and mountain range on the map could overlap with his memory, and the name was the same.

This is most likely the original world.

For a moment, Jiang Bei wanted to open his mouth and scold his mother.

He had always thought that this was another world, but this was what his original world would look like after it became the underworld.

I just traveled through time, not through space.

He rubbed his head, feeling a headache.

"It's so beautiful," he said, looking at the map in front of him, "Is this big blue the sea in the book?" I've never seen it."

At this time, he found that the Jiang Bei next to him was not big

Right: "Don't brother, what's wrong with you?"

"It's fine." Jiang Bei shook his head.

His relatives died early, so when he crossed over, he didn't have nostalgia for the past, he just wanted to live in this world and make money by the way.

Now that he knew that this was his original world, Jiang Bei's heart swelled with a sense of absurdity.

Suddenly I felt kind, and I felt pity.

The contrast is too great, I didn't expect that the world before to become what it is today.

He continued to look down.

The "Great Migration" began, and when the first people arrived near the poles, they found that the number of copies of this area began to increase.

As soon as people came, the number of copies also increased, and humans also discovered this law and began to speculate about the relationship between humans and copies.

Later, after many years of experiments and verification, they found that the frequency of burst copies is related to human emotions, and negative emotions will promote the growth of burst copies.

Thus was born the "Ark Project".

Jiang Bei already knew about this part of the Ark Project, and the content on the information was similar to what Liu Yan told him before.

He roughly glanced at the section and looked below.

The Ark Base will also be able to communicate with humans from the outside world after it is completed.

The people here communicate with the outside world and learn that the humans outside are still experimenting one after another, including the "New Humanity Project" and the "Mechanical Frenzy"

These two plans are not detailed.

The New Humans project is to genetically and brain-modify to create a new kind of emotionless human being, so that no negative emotions are generated. However, they soon discovered that this emotionless human being would be recognized as an object by the dungeon, and would be removed directly after entering the dungeon.

This plan did not work, and humans tried to modify the human body.

Dismantling the human body and replacing the vacant parts with machines, the survival rate of humans in the dungeon will be greatly increased with the help of the machine.

However, they found that if the machinery bound to the human body was too large, it would also be removed after entering the copy. People who change into mechanical legs and mechanical arms will directly become crippled after entering.

Two plans failed in quick succession.

Then came the Zero Project.

This part is consistent with what the base captain said, and the zero plan is starting to go very well, and even the real sense of the word has been wiped out, and if this trend continues, this plan may really save the world. But the probability is that the mid-range suffered a devastating disaster, and the zeroing plan was never heard from again after a certain day.

At the same time, the communication between the Ark Base and outsiders was completely cut off, and it was not until more than ten years ago that the Torch Base was contacted.

A few pieces of paper are a mere record of the struggles and rebellions of mankind over the years, during which countless people have sacrificed their lives for these projects, but only a few of them.

Why didn't he know the conversation between the base chief and Jiang Bei in the ward, and today was the first time he knew that the zero plan really existed.

"I always thought it was just a legend," he said, looking at the zeroing plan on the last piece of paper, "I didn't expect it to be a real thing...... And it says that humans have wiped out replicas. Since humans have wiped out copies before, we might be able to do the same. Our base has always been at an absolute disadvantage, and we have been passively cleaning up the dungeon, and if we can master the method of actively destroying the dungeon, then the base may be saved."

It's a pity that the base also doesn't know much about the zeroing plan.

It is only known that this plan has caused a very small number of people to change, and then through these people to destroy the dungeon.

They don't know exactly what kind of change, and by what means the changed person is a copy of it.

"We don't know much about this plan, and I think other human bases may know something about the Zero Project, but unfortunately the information launch pad is out of order to communicate with them, and the base is running out of time......
