I Will Use the Genshin Impact System to Kill Tianli

Jiang Cheng, a low-school student preparing for the college entrance examination, accidentally brought the world of the original god to the real world because of a failed confession. What followed was that Tianli summoned evil monsters to annex the real world, but the real world was not prepared at all. And people in the real world where Genshin Impact exists suddenly seem to have lost their memory and don't remember the game Genshin Impact at all! How should Jiang Cheng and his characters save the world? This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
