The way of heaven has been greatly updated to overcome the tribulations. The "nine lifetimes" tribulation involves Yu Xin, the master of Yixing Palace. After nine lifetimes, he can return to his normal life as a palace lord. Of course, in the process, he also found the person who would appear in his tribulation every time.
Purpose: Love is destined for one person's life. No matter how difficult the process is, love will last until death.
