I just played yesterday, and I just stopped playing for 30 days. I borrowed Gao Xing Wuming and hid in the upper left room to slowly grind for a few minutes without selecting the health status.

Bring two shields and start a high-level battle with Wu Ming. Go directly to the boss's face and do crazy output. When the boss uses skills, switch characters or dodge or use skills. It is best to have a true white who can restore blood. Beat the boss to death and then attack the mobs. It's a brainless and fierce act.
