Zhang Cheng: "*System, how can I get back to Lan Xin?" System: "It's not difficult, just be invincible in Teyvat." Zhang Cheng: "…" Zhang Cheng: "6" So Zhang Cheng started his "invincible" journey to Teyvat PS: This is my first time writing a novel. Genshin Impact is only level 53. The relationship between the characters may be wrong. Corrections are welcome. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
