[Emperor Armor + Genshin Impact + winning over characters + no System + decisive and ruthless + not mindless wish fulfillment]
(The protagonist's power will scale according to the destructive feats shown in the TV series and movies. He'll definitely be holding back early on. What fun would it be if he weren't nerfed?
Also, the protagonist and Teyvat exist in different dimensions. The Heavenly Dao of the three-dimensional world can't control the heavens of the two-dimensional world; they have nothing to do with each other. If you insist on splitting hairs, please exit to the right.
Finally, this novel is just for fun. If you like it, please support it, and that'll motivate me to keep updating. If you don't, you have other choices. No pressure.)
My name is Ziyang, Chen Ziyang.
I am the purest-blooded summoner of the Emperor Armor in five thousand years, since the Shadow Realm invaded Earth. In my generation, I have nearly wiped out every mutant beast on Earth by myself. Even the ancient ultimate demon beast they cultivated by exploiting a loophole was hunted down by me, from Earth to beyond the galaxy.
However, the energy released by our battle was so immense that it fractured space and formed a black hole, which swept me inside.
When I woke up again, I found that I had somehow arrived in Teyvat…
You really underestimated the strength of the Emperor's Armor, and it's still in the fifth dimension. You also overestimated Teyvat. A skinny camel is bigger than a horse.
Your acting style is too timid, you should be more decisive
Not bad, I think
