Conquering Teyvat in Iron Armor

What would happen if an ordinary person transmigrated to the world of Genshin Impact with an Iron Man suit? Would they dominate the world, or hold their own against its strongest?

A labor of love from a tiny workshop, a masterpiece of history, a premium history, a rare history.

The purpose of this work is unclear, and its characterization is vague. I seriously doubt whether the author has even a basic command of language (•̀ᴗ•́)و̑̑
