Genshin Impact: Reincarnated as Hat Guy, I Awaken the National Destiny System

I'm not a hater, so please don't flame me!!!

After I said "Third Brother" to my phone, it exploded right in my face and sent Su Yun straight to Teyvat.

Looking at his puppet body, Su Yun felt like the sky had fallen.

Su Yun: Oh no, I've become Third Brother.

Luckily, he awakened the National Destiny System at a critical moment and escaped Inazuma. With the System's help, he also saved Greater Lord Rukkhadevata and became Sumeru's Grand Marshal.

Su Yun: I shall command all the armies under heaven and unify Teyvat!

Who knows how many years later, when the sleeping Heavenly Principles awaken and see a unified Teyvat, they fall silent.

Heavenly Principles: Where the hell am I? Is this even Teyvat anymore?

Su Yun, with Istaroth in his right hand and Ronava in his left: Heavenly Principles, come down willingly. I can still give you a dignified ending and a place among my consorts.
