Luo Lie, a tough-talking and soft-hearted young man, was exposed as a "trash" in public during a sect competition and became a street rat that everyone shouted at. But he didn't know that the first ancient killing array - the Nine Tribulations Tianluo Formation - was sealed in his body. Every time he experiences a life-and-death crisis, the formation will activate a level, giving him heaven-defying combat power. However, the owner of this formation is not a kind person. It is more like a "humanity experimenter", constantly testing Luo Lie's limits with loneliness, betrayal, and desperate situations. When Luo Lie said vehemently, "I don't need friends" time and time again, he couldn't help but take action for others; when he said with a smile, "I've long been used to it," his fists turned white. This is a cruel trial about "growth and loneliness" - either becoming a god in loneliness, or being destroyed in warmth. Luo Lie chose the most difficult path: with a warm heart, he fought his way through the cold world of immortality. When all the Nine Heavens are activated, what he will face is not the enemy, but the "self" who has been watching him in the darkness.
