When Lin Feng's cultivation broke through level 30, he obtained the Mirror Flow.

General Thunder, Eightfold Son of God, Ganyu, Keqing, Fu Xuan... Countless cards appeared in Lin Feng's hand. Oh my God! This is really a paper wife!
Kafka: Listen to me, anyone who wants to bully Feng will become a dead person.
Eula: I am the Wave Knight Eula Lawrence, and I am willing to be Feng's guardian knight. I will never leave you, for the rest of my life.
Jingliu: If you want to kill Feng, ask the sword in my hand first.

Desperate Tang San: I have tried very hard, but I really can’t beat even one!
