Genshin Impact: A Merchant of the Myriad Worlds in Teyvat

Su Ze transmigrates to Teyvat, where he becomes a wandering merchant. With the Myriad Worlds Merchant System, he travels between Honkai: Star Rail and Teyvat.

He starts selling all kinds of unusual goods.

In Genshin Impact

Kaeya: Fruit from the Great Voyage route? Infinite freezing? Are you sure this isn't a scam?

Zhongli: One card for everything, convenient and easy to use. Interesting, Boss. Put the bill on Wangsheng Funeral Parlor's tab... No, wait, I'll pay by card.

Su Ze: Knowledge changes your fate, and knowledge builds the future. If you want to learn more, all you need is a database.

Nahida: Wandering merchant, you absolutely must sell it to me!

In Honkai: Star Rail

Su Ze: Golden flames ignite a frigid life. You can't go wrong, you won't get ripped off. Honest deals for young and old alike, what a bargain!

Natasha: Thank you for letting the children see the sky.

Su Ze: Golden coins, round and plump, containing the power of the gods. A fine collectible, don't you think?

Herta: Mora forged from the flesh of a god? Worth investigating.

Su Ze: Scenery from different worlds, letting you experience a different life. How about giving it a try?

Black Swan: What a fascinating memory. I like it.

Years later, Su Ze has become the strongest wandering merchant. Sitting on his throne, he idly flips through the signs beside him, lost in thought.

Should he go to Teyvat or Honkai: Star Rail today? Visit old friends on the Xianzhou Luofu, or take a look around the new nation of Fontaine?

The newly opened world seems pretty interesting too...
