Holy Grail War: Summon an Emperor of the Ages from the Start

[No Female Lead + Minecraft + Fanfiction + Type-Moon + No System] A magician from an Eastern magical family is determined to become an excellent magician, but accidentally gets caught up in the Holy Grail War. The Einzberns take him on as a student to help their family claim the Grail.

The moment he recites the incantation, there's no turning back.

"Unite the four seas, bring the world to heel! By my will, summon forth the Heroic Spirits! Forge a new empire for me, and display the supreme glory of Great Qin!"

"I do not accept the ideals you pursue."

A brief yet brilliant empire, adrift in the snow and wind.

"It will all be over soon."

Become a Heroic Spirit. Analyze, combine, reconstruct Noble Phantasms.

Survive, create, observe.

"All it takes to accomplish this is a string of code."

With a casual gesture, the new Grail is reconstructed.

"Make whatever wish you desire. I'm more versatile than the Grail."

Sacrifice yourself to become another person's guardian.

(There are lots of Minecraft elements and lore. I'll stick to the main story, covering the Holy Grail Wars in order, including the movies, then the Singularities. That's roughly the plan, and I'll revise it later.)
