Lin Xuan was an ordinary office worker on his way to work one day until suddenly, he was fatally hit by a car, ending his life. Fortunately, Lin Xuan transmigrated to another world, a world where mystical energies and monstrous beings roamed free; unfortunately for Lin, he had transmigrated into this world as a giant Toad.
Lin Xuan later discovers he has acquired a breathing cultivation method, enabling him to absorb moonlight essence and devour other creatures to increase his blood qi. This process gradually augments his powers, inching him closer to a significant evolution.
While navigating this completely Surreal world, Lin Xuan encounters a black snake; seeing the potential benefits of working together, the two form an unlikely alliance and work together, facing other demon beasts in hopes of evolving and becoming humans again. Lin Xuan's Toad form evolves through different stages as he defeats and absorbs blood qi from other creatures.
Will Lin Xuan uncover the mysteries of his transformation and the secrets of this mystical realm? And what unforeseen challenges await him as he ventures beyond the forest into the vast, mysterious world? What will Lin Xuan's ultimate form be as he keeps evolving to more powerful forms?
