Zhou Yan found out that he had traveled to the world of immortality and wanted to hang out casually.
I don't want to be tested for the best immortal bone when I join the Jiuyuan Sect with a long-term meal ticket, and I am born with a harmonious Taoist heart. From then on, he was forced to make progress, and the sect elders talked about it every day, and the ducks were full.
Later, Zhou Yan finally made up his mind that someone had to go down this road. Even if there were many difficulties and dangers, he would not give up this unique opportunity. He must become a saint.
Later, Zhou Yan realized that unique might not be a good word.
