The Hilarious Villain Is Magnanimous

My name is Wu Dashen, and I have been living with my grandfather Wu Hongliang for more than ten years. I have been weak since I was a child, with a pale face and thin body. This is the symptom of the body being hollowed out... I always hope to be cured one day. And on that day I will transform from a "little kidney" to a "great god" in an instant, and from then on I will stand tall and unyielding. This day finally came to pamper me... The seeds stored in Wu Dashen's Dantian shone with golden light, and a golden plant that resembled a tree or a vine emerged. Warm, soft, comfortable... Wu Dashen controlled his thoughts and entered it, blending into it, and he couldn't extricate himself from it! Hey-hey! I, Wu Dashen, also have a cheating artifact, eh? But why no matter how Mao teased it, it didn't react at all? Wu Hongliang stretched out his hand and put it on Wu Dashen's belly, and directed a stream of Qi into Wu Dashen's Dantian. A sudden mutation occurred, and the tree vine stretched out a root to instantly swallow the invading Qi. Wu Hongliang was shocked and turned pale. He wanted to stop his hand but was firmly sucked by a suction force. "Grandson, hurry up... Stop that thing of yours, you won't even let grandpa go!" Wu Hongliang shouted hurriedly. Wu Dashen's face was full of black lines, "You deserve it, Grandpa, you are so old!"
