Shen Yuanbai has been an immortal for thousands of years, without desires, demands, ruthlessness and love for thousands of years. He thought he might live like this forever. But there happened to be such a person, who seemed to be destined to pierce his life like a thorn in every life. Even though they were hurting and hurting each other, in the end, Shen Yuanbai and Mu Junyan had to admit that no matter how long it took, no matter how many ups and downs they experienced, how many lives they went through, as long as they would meet each other again, the love and affection that would destroy the world would be poison in their bones and blood that could not be eradicated.
