I Am A Stumbling Block For The Villains

In the eighth year of Yanji, the Demon Lord was defeated by the sword of Qingxuan Zhenren, the top master of the Immortal Sect. After that, the sun shone and the world was peaceful.
But no one knew that the real cause of the Demon Lord's defeat was that he tripped over a small stone. Master Qingxuan picked it up and the poor "hero's stumbling block" was trampled to pieces on the spot.

When Shi Jiang woke up, he transformed into the...villain Demon Lord...under his feet...er...the stumbling block...there were still two hundred years before he would be trampled to death...
Shi Jiang felt that the problem was not big. As long as he killed the BOSS first, he would be able to avoid future troubles forever and everything would be fine.
Unfortunately, the "Immortal Tribulation" that Shi Jiang read was a pirated version. The real name of Demon King BOSS was harmonized by the anti-theft system into "Kou Kou"? ? ?
As a result, Shi Qiang was forced to embark on a long journey to find the BOSS. He would rather kill a hundred by mistake than let one go!

Suspect No. 1: The legendary old monster who has lived for three thousand years
Old monster: Damn it, I am your master!
Suspect No. 2: The tall, handsome and poor swordsman
Swordsman: Girl Stone, you misunderstood...
Suspect No. 3: The beautiful and poisonous female pottery maker
Female pottery maker: This little stone is hard and poor!
Suspect No. 4... is being searched for...

After many years of going around in circles, Shi Jiang finally confirmed the identity of the Demon Lord, and was greatly annoyed: It really is you!
The man's eyes were as still as water, and he said gently: "This is inappropriate, you are obviously my inner demon."
