First, let me apologize if my words offended you, the author. and as for the idea of spreading anime on teyvat, if what you need is someone who can build a computer and set up a network that can connect to all countries, you don't even need to call Veldora or Rimuru, I mean... there are robots in Teyvat, also Sumeru already has a network in the form of Akasha, and don't forget that in Fountain there are mechanical fish to organize and survey the environment that we can catch with a fishing rod, so if you don't see the presence of computers in Teyvat, it doesn't mean that they don't exist, they are just waiting to be discovered by you . (Google Translate)

Ryuhei, as someone who was reincarnated in Teyvat but didn't know that the world was a game world, here he treated a life and death battle as a way to gain experience.... honestly, it sounded stupid to me (google translate)

So... StormTerror (Dvalin) vs Storm Dragon (Veldora)?
