True? From youth to old age, I'll stay by your side until the very end.
Zhaoxin Pavilion says, "I have three disciples in my life. The first is an ungrateful wretch, the second became a watchdog, and I'm raising the third..."
The eldest disciple mastered his studies, switched to cultivating ghosts, and made a life's work of swindling people, targeting his own master in particular.
The second disciple mastered his studies, then chose to go their separate ways and live their own lives, becoming a forest ranger steadfastly devoted to their homeland.
The lonely master had only just returned from the brink of death when he found his youngest disciple. If the first two were geniuses, this last one was a hopeless case. How do you teach a hopeless case? Hand over hand, no hesitation, just do it!
Unfortunately, before the third disciple could graduate, the master went to live in the Demon Realm.
Word had it that the Demon Realm had changed hands, and its bloodthirsty ruler had graciously offered to step down. The third disciple followed him to the Demon Realm, only to discover that the new Demon Venerable was their own master, and the Demon Venerable's wife was their grandmaster, who had been in seclusion for ages.
After a series of twists and turns, in the end, the righteous path remained the righteous path, and master and disciple returned home together.
