Am I Not a Natural Disaster? Why Do They Call Me Ancestor?

Xiao Jin died due to losing too much essence and blood while refining the Gu. However, he accidentally traveled to a fantasy world and became an illegitimate son of the royal family who was kicked out of the family. He was ridiculed by everyone as a "natural disaster". Due to his special constitution, refining Gu is as easy as breathing. Xiao Jin: Are you saying that refining the poison essence and blood is almost not consumed? Awesome From then on, Xiao Jin's daily life: practicing, going out to find suitable Gu insects, and refining Gu. A few years later, he looked at the thousands of Gu insects behind him and smiled with satisfaction. The opponent is too strong? Wouldn't it be better if the Gu worm absorbed his spiritual energy? The royal family doesn't want to see him? Sorry, go talk to my army of Gu insects. In the academy competition, when his opponent saw the Gu insect behind him, his legs softened and he knelt in front of him: "Ancestor, don't kill me!" Xiao Jin: Huh? Am I not a natural disaster? They call me ancestor no matter what.
