Cultivation of Immortality with Strange Patterns: from Totem Tattoos to Hell Scrolls

Traveling to the world of cultivation where demons are rampant, I find that I actually have a game-like proficiency panel. Others have been practicing hard for ten years, but he is not as good as him in painting a strange pattern. When the major immortal sects are still competing for spiritual veins, he has carved taboo totems all over his body. From the lowest [Crow Pattern] to the legendary [Underworld Flower], every time a pattern is unlocked, it will have more power to devour the world. Until that day, the Nine Heavens Thunder Tribulation fell, and he shed his human skin, revealing a wriggling scroll of hell - it turned out that the so-called cultivation of immortality was just the grandest sacrifice prepared for his body.
