Genshin Impact, Pouring Polluted Water Back at the Beginning Is Not Too Much, Right?

"Genshin" "Doujin" "No system" "Water Dragon King" "Single heroine" "Funny" Four years ago, Sakura Country ignored dissuasion and discharged polluted wastewater into the sea. Disaster ensued... Was it God's condemnation or the release of the Water Dragon King's wrath... Four years later, a new student came to the School of Elements. Are you called a scumbag at the beginning of school? Small scene, Have you lost face since school started? It doesn't matter, Does everyone know that I'm stupid? Then... It's okay, Wait until I announce the news about living with the goddess and scare you to death! PS: It adopts the settings of Genshin Impact and is partially original. Please be merciful if it offends the XP party.
