I have never heard that martial arts cultivators can cultivate immortality and rejuvenate themselves!
The eighty-year-old Wu Zunyan Tianya transformed himself into a ten-year-old child during his retreat and cultivation. He was also kicked out as an assassin by his disciples, which was really a big problem. (Yan Tianya: You little bastards, let's see how I deal with you after I regain my true form QAQ)
After wandering in a foreign land for three years, he finally returned to his true nature and planned to return to the Immortal Family to cultivate immortality. However, he met his former apprentice Xiao Se - who turned out to be the elder of Xilinmen, one of the five immortal sects? !
Uh, Se'er, as a teacher, you know it's not good for you to cheat your apprentice out of money. Can't this be counted as the previous tuition?
