As soon as he hears that the battle is going on, Luyue rushes to help Cai Ming and Lin Qiyue. He knows that Cai Ming is stronger than the other two, but he also knows that Lin is weaker than Cai Ming. He is afraid that Lin will die if he does not leave the battlefield. He hears the roar of the tiger and runs to get help. He sees that the quadruple-heavenly demon king has escaped through the side of the mountain. He tells the demon king to blame himself for thinking Lin is his weak point. The truth is, according to the book of yuanchu-mountain, demon-slayer-sword is a divine weapon. It can absorb more demonic aura and become more evil. Since Cai Ming has reached the third stage of his primal soul , he believes that he can control this evil weapon. The bag that he gave Lin contains a lot of valuable things, and Cai Ming returns to the battlefield to find out what has happened. He finds out that Lin has lost the battle and that Lin and his babies are all good. He thinks that Lin's father is dead, but Lin says that he has just left the mountain a long time ago.
