I Returned from New Three Kingdoms and Somehow Ended Up in Type-Moon

Su Yuan accidentally transmigrates to ancient times, specifically the Three Kingdoms period.

A voice from somewhere tells him that he can leave if he accomplishes something great.

He plans to use his knowledge of the future to make a name for himself, then return to modern times and enjoy life again.

But the moment Su Yuan sees Cao Cao, his world comes crashing down.

What the hell, why is this the New Three Kingdoms?!

His knowledge of the future can't withstand the erosion of fate, and Su Yuan dies again and again in the world of New Three Kingdoms.

After each death, he wakes up again at a different point in time, with a different identity.

At last, Su Yuan finds a chance to die alongside Lu Bu, the Three Kingdoms' greatest punching bag.

When he wakes up again, he's in Japan in the 1990s.

Good news: he's back. Better news: he's gone back to a time before he was even born.

From the protagonist of a transmigration story to the protagonist of a rebirth story, I'm definitely going to be a plagiarist!

With Fate/Zero, Su Yuan becomes a bestselling novelist, enjoying both wealth and fame, with financial freedom at last.

That's what he thinks, right up until the day the source of all evil in this world comes knocking.

"What the hell! What do you mean I left New Three Kingdoms only to end up in Type-Moon?"

"What do you mean New Three Kingdoms counts as the Three Kingdoms, and I count as a Heroic Spirit?"

Facing all the mighty and extraordinary figures of the Nasuverse, Su Yuan has to show them what the mighty hand of fate can do.

He'll make them understand what it means to be eroded by fate.
