After listening to Liu Fu's analysis, how to seal the heavens online and the inner world, Lake couldn't help but think of the book-burning pit Confucianism and the Terracotta Army.

The book burning pit should be to erase this ancient main world, all the documents that record the online and inner worlds of the heavens. Let the world, there is no trace of the existence of the heavens online.

As for the Terracotta Warriors, it is very likely that the Heavens Online player warriors have all been turned into ceramic terracotta warriors. Let all players in the heavens online die, or turn into combat terracotta warriors in a special way.

In this way, the sealing conditions envisioned by Liu Fu will meet two.

Lake began to think that the Great Wall built by Great Qin should also be used to fight against the Avatar army in the inner world.

Before the Terracotta Warriors and Book Burning Pit are pitted, they must first send all the Avatar armies in the inner world back to the teleportation gate of Zhao State, or kill them all, in order to meet the conditions that Liu Fu said, and seal the heavens online and the inner world.

Now, Lake finally feels that he has an idea through this copy of Qin Shi Huang, and the idea of completing the main quest has become much clearer.

Liu Fu's idea of the old Taoist priest should be right, with his thoughts, he can indeed seal the Heavens Online, so that the Heavens Online was sealed about two years ago, and then it will appear again in the future.

"Now, all we have to do is defeat the Avatar army first. The civilians of the Overworld, who are much more numerous than the players, let them contribute as well. Otherwise, these people will also be put away, this is our strength, and it would be a pity not to use it. Lake said.

After listening to Lake's words, Liu Fu and Li Si felt that there was some truth. The two of them thought about it, but they couldn't figure out for a while what to do for people who were not players in the main world.

Lake decided to remind them that he still wanted to clear this dungeon and bring out the Great Wall of Black Technology from the dungeon world, and go back to the future two thousand years later to fight against the giant beasts and the invaders that came after.

In ancient times two thousand years ago, if you didn't build the Great Wall of Black Technology, you wouldn't be able to see the Great Wall of Black Technology, but you wouldn't have a chance to take it out.

"How about building a towering wall in our Overworld. It is best that this wall has some special abilities compared to ordinary walls, which can allow our soldiers to stand on it and improve their combat effectiveness. And the previous battles with the Avatar army have proved that there are city walls, which are more suitable for our warriors to fight against the Avatar army. Lake said aloud.

"Yes, build the walls, Ryker the Great is wise!" Lees said.

"If the city wall is short, it has no effect. There is a formation that can be fused into the city walls. But the wall must be long for the effect of the formation to be revealed. Liu Fu said.

Lake smiled and nodded, it seems that the Great Wall of the Great Qin Empire can indeed be built.

But it's not the same as I expected before, it's not the Great Wall of black technology, but the Great Wall of formation.

In the history that was erased two thousand years ago, the Great Qin Empire used the Great Wall of Formation to fight against the Avatar army.

If it's just the Great Wall of Formation, your own black technology alchemy ring may not be able to bring this copy of the Great Wall design drawings. His own black technology alchemy ring can bring out scientific and technological items.

The Great Wall of Formation, no matter how you look at it, doesn't look like a high-tech item.

We must let the people of this world build the Great Wall of science and technology, Lake began to think, the Great Wall of Formation, listening to Liu Fu's old meaning, the power should be good after it is really built.

There is no reason for him to refuse Liu Fu to build the Great Wall of Formation.

But if you let the formation of the Great Wall, combined with technology.

Build the Great Wall that combines the formation with the technology of this era, and you will have the opportunity to bring out the alchemy ring of your own black technology.

"The idea of a formation city wall is good, but I feel that just a formation plus an ordinary city wall is not enough. Are there any other techniques that can be added to the buildings of the city walls that are also suitable for defense? Lake said.

Liu Fu took a step forward, "Your Majesty, I know that there is a hidden organization among the people, and this organization will create some special items, and there are many skilled craftsmen who are good at various mechanisms. This hidden organization is called the Mohists. The founder of the Mo family was Mozi, a strange man. I went to find someone and asked the head of the Mo family if they could integrate the mechanism technology they created into my formation city wall. ”

Lake was overjoyed when he heard this, he had just come to the Great Qin era before, and he had inquired about the Mo family, but there was no news at all.

I still thought that this Great Qin did not exist in the Mo family.

It turned out that the Mo family existed in ancient times, but it was hidden too deep and I didn't find it.

The Mo family is good at defending the city, and can create weapons and many mechanisms to defend the city. These technologies of the Mohists should be regarded as the technology of this era.

The mechanism technology created by the Mo family is integrated into the Great Wall of Formation, and after the Great Wall is built, it should be able to be judged as a scientific and technological item by the black technology alchemy ring.

Lake smiled, when the time comes, this Great Wall of Science and Technology Formation, after clearing the customs by himself, he will have the opportunity to bring the design drawings back to the earth two thousand years later.

"Liu Fu, give you a task, be sure to find the heirs of this generation of the Mo family, and let the techniques such as the Mo family mechanism be perfectly combined with your formation to build a city wall. In our Overworld, build a wall that fuses Taoism and Mojia mechanisms as soon as possible. This high wall is called the Great Wall, and the longer it is, the more powerful it is, the better. In the Overworld, you can call on the human and material resources of all countries. Lake said.

"Your Majesty Xie trusts, Weichen will make every effort to build this Great Wall." Liu Fu kowtowed and said.

"Your Majesty, in fact, the non-player civilians in Great Qin, we have to be transferred. But the other six countries, after all, we are not kings, it is somewhat difficult to mobilize. Weichen has a plan, as long as it is successful, it will be easier to deal with the Avatar army in the inner world, and it will also allow the territory of the Qin State to expand. Li Si spoke on the side.

"Say!" Lake asked Lees with some curiosity.

The strategy that Li Si, the main battle faction, then said, made Lake feel a little cruel.

[The teleportation gate in Xianyang City in the inner world, our Qin country players and soldiers will not guard it first. For the time being, let the soldiers of the Qin State pretend to be invincible, and let the Avatar army enter the Xianyang City teleportation gate. Later, in the Overworld, lure the Avatar army and attack the other six countries. When the fight is almost over, our soldiers of Daqin will block the passage of the Xianyang City Teleportation Gate]

[The Avatar army that invaded the main world, without backup, was wiped out by the Six Kingdoms only a matter of time. After that, the six countries that fought with the Avatar army will win, but their troops will be depleted. At that time, Your Majesty, you will raise your arms and shout, and call against the invaders, unify the seven kingdoms of the world, and join forces to fight against the Avatar army. The remaining six nations have been invaded by the Avatar army, and their people will choose to defect to the powerful Qin state. 】

[At that time, as long as some news is released to the outside world, those who do not take refuge in the Qin State will not send troops to assist when the Avatar army invades again. 】
