After Erqing returned to Xuzhou City, he stayed for ten years.

In his spare time, he took Da Bai and Yang Chan to play in Qinglian World.

Although that world is not vast for them, it is also the size of Nanganbu Continent.

It is shaped like a rooster, with a mountain range in the south, a vast grassland in the north, and two large rivers, one south and one north, running through it from west to east. The earth is surrounded by the sea, and the islands are like green gems, like stars, dotted in the blue sea.

In the center of this land, between the arches of the mountains, there is a lake, like a jade treasure mirror, inlaid in the heaven and earth, surrounded by cliffs on three sides, and facing the forest on one side.

The ancient trees on the cliff support the sky, and the vines spread.

If you look closely, you will find that this lake is quite similar to Qingcheng Mountain Mirror Lake.

Whether it is the green bamboo building in the center of the lake or the aura-filled medicine garden on the island in the middle of the lake, they are exactly the same as Qingcheng Mirror Lake.

The only difference is that there is no 'white-clothed cave' here.

And ten years, enough time for the other half of Erqing's Yuan Shen, in the land of the source of the Dao, to transform those laws that he had already comprehended into the Great Dao Imprint.

Therefore, this half-primordial god of Erqing is also constantly transforming this world. Although he couldn't vigorously mobilize the chaotic qi in the Void Storm, he had no problem absorbing it slowly.

Therefore, the world is still slowly growing and getting bigger.

......

At the same time, his other half of the Yuan Shen also built a city hundreds of miles away from this Mirror Lake.

It was a huge, wallless city, and it was also the only city in this Qinglian world, and it was called Ten Thousand Demon City.

The area of the Ten Thousand Demon City is vast, built around the mountain, and the mountain is named the Ten Thousand Demon Mountain by Erqing.

The Ten Thousand Demon Mountain is not very high, but standing on the Ten Thousand Demon Mountain, you can look around the entire Ten Thousand Demon City built around the mountain. On the top of this Ten Thousand Demon Mountain, there is a palace called the Ten Thousand Demon Palace.

The Ten Thousand Demon Hall is the place where Erqing and the people who manage the Ten Thousand Demon City are in charge.

And the monsters in this Ten Thousand Demon City are all from the spirits of Qingcheng Mountain, as well as the monsters who have been saved by him on the side of Beiju Luzhou.

Erqing has taken the time to take these two groups of monsters to the Qinglian Heaven and Earth. Then, he imitated human beings, built a demon city, and occasionally opened an altar in this demon city**.

Because of this, those monsters did not escape into the mountains and forests, but stayed in this city of ten thousand demons.

Although most of these monsters can already be consumed, the so-called 'Bigu', some still need food to survive.

However, there are no other creatures in this world, not even animals.

So, Erqing introduced the method of cultivating land and animal husbandry of human beings, and taught those monsters and monsters to live like a normal human.

He knew that it was not something that could be done overnight to get these monsters to change their living habits and create a demon civilization.

However, this is his world, which can be changed according to his heart, and he has enough time to make these changes.

He felt that monsters should not have to drink blood, kill each other, and eat the weak...... At the very least, the weak must be guaranteed the right and the opportunity to live.

As a result of cannibalism, they can only breed barbarism, but not civilization.

Demons can seek freedom, they can pursue unrestrained, but they should not be synonymous with barbarism and blood, they are also intelligent beings, and they should also have order and peace.

Not all youkai like to fight, and they are brave and ruthless, and there are many youkai who are naturally peace-loving, innocent and romantic. For example, the butterfly demons in the Valley of Flowers and those flower demons.

Even some of the people who like to fight...... He felt that the struggle under the rules and order was the basis for ensuring the progress of demon civilization.

Everything should be built under the rule order!

Therefore, he took this Ten Thousand Demon City as a pilot, trying to create rules, create order, and guide the demons to develop in the direction of freedom, democracy, equality, justice, integrity, fraternity, and the rule of law.

Those big and small monsters all regard him as a holy master, and although they have some doubts and incomprehensions about his arrangements and decisions, and the rules and order they have established, no one will oppose him.

But Erqing also understands the importance of public opinion, so after 'brainwashing' the little finch and tigress, as well as the monkey, the old ape, and the old cow, let them be the commentators.

With the slogan of 'building a harmonious and civilized country of all demons', Erqing easily fooled these 'disciples'.

And let them fool those monsters who already worship Erqing so much that they can't attach it, and naturally it is very easy to turn those monsters to this road of no return.

In the City of Ten Thousand Demons, almost every monster will recite those slogans.

But whether it can be done or not, it will take time to slowly correct and run in.

In the face of these little demons with basically zero life skills, Erqing had no choice but to 'turn' back from the human world to many human craftsmen, and let those craftsmen teach those monsters.

For this reason, he set up a 'Ten Thousand Demon Technology Academy' in this Ten Thousand Demon City, specializing in teaching all kinds of knowledge. Including but not limited to agriculture, animal husbandry, medicine, metallurgy, pottery, wood and other majors.

When those humans who were 'abducted' by Erqing found out that the students they taught were actually demons with special appearances, they were directly dumbfounded. A few even had cardiac arrest, but fortunately the treatment was timely, otherwise it would have been fatal.

However, after getting along for a while, these human instructors found that although these monsters were a little ugly, they were unexpectedly respectful of their teachers.

It even makes them feel that these youkai are not youkai, but humans in the skin of youkai.

Three years after the professorship, the human faculty members were paid for some gold, silver, and jewelry, and when they were put back, it was like a dream.

When they told their neighbors what they had seen, no one wanted to believe it.

But they weren't stupid enough to prove it.

Among those professors, there were even those who were willing to return to the Ten Thousand Demon City. Although these people are all lonely people who have nothing to worry about, they are willing to stay, and Erqing is naturally infinitely welcome.

This is also a special case of harmonious coexistence between humans and demons.

And this is what Erqing has always wanted to do.

It's just that at that time, he didn't expect that he would create a world.

Yes, although he had thought about letting demons and humans live in peace, he had never thought about creating a demon country, because neither Heaven nor Buddhism would allow this kind of thing to happen.

But in his world, that's up to him.

As for the scientific disciplines of physics and chemistry, Er Qing himself couldn't figure it out, let alone those humans in the human world.

Well, he didn't let anyone do it.

After all, this is a world of myths, and many things, are contrary to science. 2k reading web
