The Journey of Hedao Started with the Death of Family

He was the young master of the Immortal Sect, but his sect was destroyed. The murderer destroyed all his immortal magic, cut off his meridians, and left only the Life Pill, leaving him alive in the world. How can he, who is gentle and kind by nature, seek revenge? What changes will a black cat he encounters by chance bring to him? PS: This book is a world of its own, with a unique cultivation system. If there are any unclear points, please point them out and please bear with me. Thank you.
