My disciples come from Earth

After his master died, Li Xiaoyao became the head of the Xiaoyao Sect, but he was not happy because he was the only one left in the sect.
In order to promote the Xiaoyao Sect, Li Xiaoyao began to recruit disciples, but he found a group of strange disciples -
They have strange habits, such as being keen on changing their appearance and names; they are fearless and are willing to kill a little demon even if the whole army is annihilated; they always have some strange ideas, even if they are always obsessed, they will modify the skills and Taoist techniques randomly, and they also say that they are DIY players...
They call themselves the fourth disaster.
