Fall and rebirth: Demon Lord Xiao Jin was betrayed by his beloved Taoist companion Luo Qingshuang and his best friend Xuan Yangzi at the last moment of his ascension. When his soul was shattered, he activated a secret technique and was reborn back to the time when he first entered the world of cultivation three hundred years ago.
Correcting mistakes: After rebirth, Xiao Jin decided to change his past wrong choices and gave up joining the righteous Xuantian Sect. Instead, he chose the Netherworld Palace, a demonic sect that was hostile in his previous life, and at the same time made plans to deal with future crises.
Demon Gate Trial: Xiao Jin showed extraordinary strength and scheming in the entrance trial of Netherworld Palace, attracting the attention of elder Mo Tianxing. At the same time, he discovered that his former enemy Xuanyangzi also appeared in the trial.
Dual identity: After passing the trial, Xiao Jin was accepted as a direct disciple by Leng Wufeng, the master of Nether Palace. At the same time, he secretly traced the true identity of Xuanyangzi and found that he might be an undercover agent planted by Zhengdao.
Opportunity in the Secret Realm: In the secret realm trial arranged by the sect, Xiao Jin outsmarted the ancient inheritance "Nine Netherworld King's Technique" that should have belonged to Xuanyangzi, and set up a trap to seriously injure Xuanyangzi, sowing the seeds of future revenge.
