Mo Chu was reborn. She opened her eyes to find herself in a world where a thousand years had passed. The docile animals and plants became very aggressive, and elemental abilities that existed only in stories and legends now appeared before her eyes! Fortunately, upon waking up, Mo Chu gained a nice-guy brother who had a sister complex. Unfortunately, she had a one-in-a-million sensitive constitution, so she couldn’t consume 99% of the available food. However, there would always be a solution. If she couldn’t eat the food of this era, couldn’t she come up with new food? And so, she made fries, grilled fish, beggar’s chicken, and various other delicacies that were not available in this future world. As a glutton, Mo Chu was satisfied with this outcome. However…

Spiritual energy ecovery brought about fundamental changes throughout the entire world, and posed an imminent threat to it. Chen Yang died in an accident and reincarnated to become a tiny koi fish inside the fish tank in his own home. Just as Chen Yang complained about the unfairness of destiny, he awakened the Evolution System. Thus, with his sister’s feeding, Chen Yang started his insane evolution. As the whole world sank deep into apocalypse, Chen Yang descended from the skies to crush everything.

He had evolved from a tiny koi fish to a gargantuan dragon. “This world shall be ruled by me!” When the fish playing in the waters was frightened by the net, it jumped over the Dragon’s Gate to become a real dragon. This is a story of how a loli raised a giant dragon, and dominated everything.
