The Journey of King Ashes of Teyvat

Ember, who became the King of the Ring, accidentally came to the world of Genshin Impact. Facing the vibrant continent of Teyvat, Ember, who had been fighting forever, put down his sword for the first time.
What is this, a sunset fruit? Try it.
What is this, Fatui? Poke it.
What is this, normal people? Kiss.
……
After putting down the sword, Yu Jin discovered that the sword can be used for more than just killing people, it has many other wonderful uses.
