Lu Shubai cut off seven ways to survive with his own hands, just to go back in time and space to regain the life that was wiped out by Shi Jin himself. He is no longer the gentle and gentle genius doctor, but a lunatic who walks within the boundaries of the rules, exchanging lives for lives and burning souls with souls. Shi Jin, the silent enforcer of the taboo, was once Lu Shubai's only light, but now it has become his fate that must be killed with his own hands. When time begins to flow backwards, when memories are torn to pieces and recast, the two of them stare at each other in the rain of blood - one wants to save, the other wants to kill. But who still remembers that life was bought with their heartbeats together?
