Beast Taming Era: My Big Green Worm Loves Grinding for EXP

Fang Yuan was reborn as a big green caterpillar. While the other caterpillars had already spun cocoons, emerged as moths, or transformed into butterflies, he had done nothing but grow bigger. Everyone mocked him, saying he could never become a butterfly and had no hope of growth. Fang Yuan said nothing. He simply kept eating, training hard, and accumulating experience. Decades later, when Fang Yuan stood tall in the world in the body of a caterpillar, everyone finally understood that a green caterpillar could shine in the world without following the rigid path of evolution. (Note: The protagonist retains his original caterpillar form. Only his size and color change.)
