Qin Wujiang is a mortal who has been reborn. He was originally a useless time traveler, the seventh young master of the Xiu family. However, because of his natural demon body, he was attracted by the demon cultivator and was forced to agree to the other party's request to seize the body. He lost his original body and became the seventh young master of the Qin family.
Only then did Qin Wujiang realize that he could only rely on himself in this world, and only by cultivating immortals could he live a better life.
After entering the Tianning Sect on the recommendation of his third brother, Qin Wujiang was given special care to grow up as soon as he entered. He didn't have a master, but he was protected by his powerful genius brother. But how can cultivating immortality be smooth sailing...
