Two ways. First, Lin Nasi took over the task and exchanged 1 wormhole for 1 (you can buy it from other players if you lose BOSS). Secondly, I also took the task at Uncle Lin's house. I went to the funeral home to brush the task items (I forgot my name). It costs 25 (it seems so much, I can change two). Tasks are daily tasks, which means at most three tasks a day.

I haven't seen that task for a long time. I wonder if the number of rewards is reversed? Anyway, that's it, three a day, and it must be done for more than one month and four days.
