Fairy Sword 4 Wei Zi Road Brush Toad to what level is better?

Ziying joined at level 36. If you were level 30 when you first came to Qionghua School, that would be enough.

Remember, Xianjian 4 doesn't need to brush monsters specially, unless you want to get a corpse. As long as you destroy all monsters in the current scene once in each maze, you can guarantee to reach level 56 in the decisive battle with BOSS. When I first came to Qionghua School, I was only at Grade 28.
