Before he died, Bai Yejin, who suffered from the pain of betrayal and experimentation, met Zhan Jinghao who treated him sincerely and risked his life to save him. However, Bai Yejin, who was already disabled, chose to die with the institute in order not to drag Zhan Jinghao down. Then, a miracle happened, and the dead Bai Yejin was reborn. Unfortunately, she became blind and mute, and lost the memory of her previous life (temporarily of course). Let me tell you secretly, Zhan Jinghao is actually reborn. This time Zhan Jinghao is determined to protect his baby and destroy the bad guys who have hurt his baby. So, Zhan Jinghao, Bai Yejin and their friends embark on a doomsday journey of killing monsters and destroying bad things.
