Depose The Dragon

There are dragons in the world here.
Dragon shapes come in all shapes and forms, some swimming in the rivers and seas, some soaring in the mountains, some hiding in the secluded mountains, or soaring among the clouds.
Once you rise up, you can swallow wind and snow, divert rivers and row rivers, drop thunder and spit fire, and divide mountains and avoid seas.
There are also dragons in the human world here.
The dragon among men has great ambitions, a good plan, the opportunity to contain the universe, and the ambition to swallow up the heaven and the earth.
As soon as the opportunity arises, it can turn the clouds and rain, decide the situation, set the cauldron, and become a dragon.
As a lost time traveler, Zhang Xing also wanted to become a dragon at first, but later, he found that this industry was too demanding, so he decided to change his career and go to dethrone the dragons.
It is said that we should go all the way in the world, make heaven and earth accessible everywhere, and dethrone dragons all over the world, so that everyone in the world can be a dragon.

This is an old-fashioned time travel story.
