Modern humans with their advanced interstellar technology, Feudalism humans with their cultivation path and godhood path, and lastly Zerg civilization that able to fight dominantly against those two human civilizations on their own through their sheer numbers and insane reproductions.

MC being captured by a mad scientist, unable to make even the tiniest struggle.

Here MC's body was about to be possessed by mad scientist after the mad scientist replace all of MC's bones with bones that belong to some sort of immortal angelic god.

In the process, it turn out that the bones possessed it's consciousness and thus also trying to possessed MC's body.

But before that happened it turn out that MC's cheat device: shadow servant was also possessed by godly entity who feel threatened by angelic being for trying to possessed MC's body that it's nurture for future revivals.

Thus two godly beings fight with each other inside MC's soul before they conveniently gave mutual defeat and give MC a mere mortal as third party to fish all leftover benefits such as godly ability and divine core. Yeah, plot armor is too thicc in this one. Biggest crisis conveniently turn to be biggest cheat code in the novel

He needs souls to advance his own soul, okay barely able to understand.

He uses his enemy souls, okay.

BUT why does he revenges innocent people. The people he needs to get revenge are those who command and execute the command, but why destroy an entire planet population to get revenge? He used a normal salaryman, wiped out his soul just to infiltrated in the enemy base and destroyed everyone together.

These noble families, okay that they tried to kill the protagonist. BUT why kill the servants together the civilians. The city was literally turned into a ghost city, ' ah they are loyal and can't be left behind' F*** OFF. JUST EXCUSES. Is this justifications just to kill hundreds of thousands, if not millions of people.

He had loyal people that cared for him, but because of his enemies they killed them and he could not leave a single one of his strongent puppets to protect them? Did water get into his brain, if you provoke someone, of course they will retaliate, if they not find you.

But his pursue of power made him, I don't know how to explain.

He left behind his family, his lover, his friends.

He is strong, okay. But why is he strong? I think he himself forgot.

But I will continue to read to see what will he do and feel when he gets in the apice of the strengh.
