Start Cultivating Immortality by Upgrading Dantian

After Lin Mu's erysipelas, who traveled through the realm of immortality, entered his body, a panel appeared in the sea of consciousness, and he was able to regard his Dantian as fertile soil in the cave and upgrade it: [Dantian lv1: Open an acre of thin field in the Dantian, randomly obtain spiritual seeds every day, and the crop cycle is -20%] [Dantian lv2: Space expansion, unlocking the "Spiritual Plant Bond" function, crop cycle -90%] [Dantian lv3: The space expands sharply, unlocking the "Planting Magic Weapon" function, crop cycle -90%, double output] [Dantian lv4: The space is doubled, unlocking the "small cave sky" to continuously nourish the natal magic weapon and Yuanying, the crop cycle is -90%, and the output is ten times] ....... Relying on Dantian, Lin Mu developed steadily, from "Tianling Fruit" to "Enlightenment Vine", from "Qingfeng Sword" to "Dingxu Hoe". Lin Mu transcended from the small realm of Dantian and became the "God of Creation Cave Heaven".
