[My upcoming novel, “Undercover in the Immortal Sect, but Law-Abiding,” is listed in my author profile. Please add it to your favorites~] As the strongest and most beautiful Demon Lord in the world, Ji Pei felt that clearing his name was the last thing he needed to do. In the eyes of demonic cultivators, he was the perfect embodiment of what a Demon Lord should be. But then the Heavenly Dao struck him dead, and a reputation-clearing System came knocking.. From then on, his second chance at life seemed to be under a spell. Everything he did somehow turned out wholesome and righteous, and no matter what he got up to, people handed him a good-person card. Ji Pei: …Everyone, get a grip! I'm a demon! Everyone: No, you're not. You were forced into it. Ji Pei: emmmm With his reputation as a Demon Lord in tatters, Ji Pei thinks there's still one person who can judge him rationally: Xuan Chen, the leader of the righteous sects and heir to a renowned righteous family, who was his master while Ji Pei was hiding his identity. Ji Pei: Master, I don't want to be your disciple anymore. I want to go back to being the Demon Lord. Xuan Chen: Fine. Ji Pei: ?? Even if I lose control and go mad...and destroy the world? Xuan Chen: If the sky falls, I'll hold it up for you. Right, this is the least rational one of all. He cultivated the Path of Unfeeling, but somehow got the whole thing twisted.

Blurb: Ji Yao, a former law student and now a purebred nine-tailed celestial fox, became a prospective subordinate of the Demon Lord from birth because of an agreement between their elders. Before he even officially started the job, the demonic clan entrusted him with an important mission: infiltrate an immortal sect to be ready for anything. Ji Yao never wanted to get involved in the clan's illegal activities, like destroying the world, which looked like a dead end from the start. Joining an immortal sect and taking it easy suited him perfectly. But only taking it easy... He never planned on becoming the Immortal Venerable's first disciple. “The immortal realm has countless rules, and the Immortal Venerable, who enforces the laws of all three realms, is especially strict. He's never taken a liking to anyone before.” “Then why did he take on a disciple?” “Senior Brother Ji Yao memorized every one of those rules, down to the smallest detail.” “!” When an undercover operation goes too well, the organization tends to saddle you with troublesome assignments. The demonic clan is set on making him dual cultivate with his master and breaking his master's heart of the Unfeeling Dao. If he refuses, he'll soon die from the poison. He has no choice but to comply, then run as soon as the deed is done. Years later, after he's captured, Ji Yao realizes that his master has been an even deeper undercover agent than he was. “You're the Demon Lord?” [Model fox spirit of the immortal path bottom VS dual-personality war god Demon Lord top] Theme:
