Jiang Xian has someone he hates. His university teacher, Xie Yan. The two pursue different pursuits. But Jiang Xian didn't expect that the first user of the "Retention No. 31" That he had developed by forgetting sleep and food to retain human souls and achieve immortality would be Xie Yan. While the machine was running, Jiang Xian finally got a glimpse of the secret hidden in Xie Yan's heart.
