Main characters: Lin Yu, Zennos
Introduction: I bought a Heart of God online, but when it arrived, I found that there was no such Heart of God in the game at all.
But, he bought the real thing.
The unknown heart of God burst into light, and Lin Yu had no time to react at all, and was swept to the world of Teyvat by the light.
Only then did Lin Yu realize that what he had purchased online was not the Heart of God.
It is clearly the embodiment of authority.
What kind of sparks will the materialized authority from the high-level figures of Blue Star produce when used by Lin Yu in the world of Teyvat, which is in the midst of the Demon War?
