The Evil God Resurrected and Accidentally Joined the Protagonist Group?

(It's not a brainless fun, the pace is slow in the early stage, and the world view is foreshadowed. Those who mind, please proceed with caution) His name is Sishi, which sounds the same as "God of Death", and also carries an ancient and taboo title, Satan. He is one of the ten major orders that once controlled the lifeblood of all things in the world, and is the incarnation of "Hell". Thousands of years ago, the ten major orders were high in the clouds of the world. They turned their hands into clouds and covered them with rain.

However, human beings who did not want to prostrate themselves for eternity unexpectedly received a response from the "stars" and stole the power that was almost like a god. On top of mountains of corpses and countless tragic defeats, humans finally pierced the heart of the gods with their sharp blades. The glorious ten major orders fell into eternal sleep. The history of killing gods, which was regarded as humiliating, was completely erased and replaced by a new legend woven by human hands and full of bright hope. The dust seems to have settled, and the past should be completely forgotten.

In order to get ahead of the end, the highest levels of mankind launched a top-secret plan code-named "Creating Gods." They want to personally create ten gods belonging to humans to fight against or even replace the ten major orders that are about to return, and forcibly reverse the trajectory of destruction.
