Devouring Law: Eternal Hunger

This is a world where the three realms of humans, gods and demons coexist. The world is vast and the avenues are ruthless. An Wuyang, a monk in the human world, encountered the remains of the ancient ferocious beast Taotie that could devour all things during an examination for immortality. After accidentally absorbing it, he gained the ability to gain skills from others by swallowing the soul of a strong person. At the same time, he also suffers from the curse of dying if he doesn't have enough to eat. On the long road to immortality, in a cruel world where traitors are in power and demons are rampant, how can we survive safely?
