I Study Magic in Xianmen

The Great Zhou Dynasty was plagued by evil spirits and chaos. Chen Nian traveled through time and became the third disciple of the Immortal Seat of Xuanmiao Temple in Tianyun Mountain. Unexpectedly, the master went out to travel to the immortals and took away all the money in the temple with a wave of his sleeves. This forced him, who had planned to lie down, to rely on slaying demons to make a living. Fortunately, the immortal swordsmanship taught by his master was quite reliable, and he had never been able to defeat the demons he encountered in the past three years, so he could live a good life. But three years after the demon was eliminated, the late Golden Finger suddenly came... "If you get the nine-tailed fox spirit (remnant), you can learn its clan's charm technique." "If you get the Rakshasa bird demon spirit, you can learn its clan's pupil technique." "If you get the Teng Snake Demon Spirit, you can learn from its clan..." What? You want me, an immortal disciple, to practice sorcery? Wait, this method of using monsters to control monsters seems to work quite well... This is a story about learning from a demon and developing skills to control it.
