Rather than witness all living beings, become one of them.
After living as an orphan for eighteen years, he finally got into a Daoist academy through his own efforts. But when it came time to choose a department, he somehow picked fate studies by mistake.
From then on, the eighteen-year-old was forced to play the part of a half-immortal. Good thing he also chose shapeshifting studies, or he wouldn't even be able to run away when people beat him up for telling them they were doomed to suffer a bloody calamity.
Theme: People come first
