Mortal flow, no system. Every time the immortal fate on earth appears, countless people compete for it, but few people can discover the spiritual herbs, caves, and treasures buried deep underground. Li Fei traveled through time and became a scholar, but he had an ancient bronze book in his mind. The book was divided into eighteen pages. Each page that was activated could acquire a magical power. [Tongyou], you can see through the ground at a glance, sneak around easily, and collect medicines and treasures. [Underworld Garden] accelerates the growth of spiritual grass, and can also breed top-grade metals, sacred trees, and spiritual springs, so you don't have to worry about refining elixirs and weapons. [Earth], summon the surrounding monsters for my use, and I no longer have to worry about being beaten in my fighting skills. ... From now on, I am in charge of the underworld!
