[Gui Qin] I Am an Immortal, but I Use Deception to Enter the Tao

Real Immortality! Cruel, Dark, and Unscrupulous to Achieve the Goal!

I want to read a book similar to "Lao Snake's Cultivation of Immortality!"

Want the Male Protagonist to Join the Demon Sect and Practice the Demon Sect Skills

The current protagonist of the Demon Sect is revising his martial arts every day, but the boss of the Demon Sect still can't tell! Are you hiding it well or are the bosses all moles? The protagonist is not required to kill people and practice martial arts, only the male protagonist is required to practice the magic sect's own martial arts. Don't accept books where a few people are all monsters

The Protagonist Is an Evil Cultivator, Decisive in Killing, Highly Intelligent, Not a Holy Mother, Not a Harem.
