Sequence Descends: Starting from Punching in Uncle Nine

This is a very chaotic world!
There is not only Huo Yuanjia here, but also Uncle Jiu, the leader of Xiling Mountain, Chen Yulou, Master Zhang of the Nine Gates, and Qin Shihuang, who was cursed by a foreign evil god and turned into a three-headed flying lizard!
If it only stops here, then how can this world be considered chaotic?
When Wu Yao met Qin Shihuang for the first time, Gu Yi, the supreme mage, ran out!
Facing such a chaotic world, he originally thought that he had signed in and obtained the "River of Eternal Darkness", one of the nine sources of the mysterious world, and that the path he would take in the future must be to become the "Grim Reaper" of this world.
But in this world where warlords are fighting, peeping from other places, the people are struggling to survive, cunning is rampant, and monsters are rampant, Wu Yao feels that he should do something for the country where he was born and raised.
Coincidentally, at this time, he punched in and obtained the "wilderness of knowledge", one of the nine sources in the mysterious world, and then he decided to contribute his own strength to the revival of this country.
Wu Yao swears that in this life, we will never let those great powers get stuck in our necks and let them use technology to limit our development!
Since then, Wu Yao has transformed into a shadow that exists in the light, while slaying demons and reducing the source of disasters, while using the power of knowledge endowed by the "wilderness of knowledge" - "the demon of knowledge" and "the secret of madness" His own country has opened up a road of alchemy technology that is different from that of the great powers. He wants to see how the great powers in this life will fight this oriental dragon?
It's just that the weirdness of this world doesn't stop there? ...
