Three hundred years ago, he was Yun Zheng, a powerful man in the Tianxuan realm in the Xuanyuan plane, but he was betrayed by his best friend Mo Chen and was poisoned by the strange poison "Erosion Spirit Powder". When he was on the verge of death, he fought for his life with the unknown Bronze Secret Book of Reincarnation, and was actually reborn in the Zhenbei Marquis Mansion of the Great Xia Dynasty - becoming the "good-for-nothing legitimate son" Yun Zheng who was ridiculed by the whole capital for being unable to practice.
As soon as he woke up, he was trapped in the forbidden land of Kunlun. Facing the killer sent by his concubine Yunsong, he relied on his three hundred years of combat experience in his previous life to easily fight back with a rusty iron sword. The fragments of the bronze secret book suspended in his dantian are not only witnesses of his rebirth, but also contain secrets that could subvert the world.
From then on, he wore a dandy's coat as a cover and held a three-foot green blade as a sharp weapon. The "waste" of the past is no longer the vision and means of the Tianxuan Realm, which will set off a storm in the Great Xia Dynasty: those who bully others will be repaid a hundredfold; those who insult others will be expelled with the sword! When the Xuan Qi is reunited, the world will know that Yunzheng is back!
