I'm Building Phones in Teyvat

Step 01: Promote phones across the entire world of Teyvat.

Step 02: Popularize gacha mobile games.

Step 03: Create a complete "modern culture." Spread a "diverse world" across the entire galaxy.

Have I got this wrong? I'm supposed to promote phones in a fantasy world?
