Why did Zhao Gao eat so much egg yolk before he was castrated in the TV series Myth?

Because the yolk is too dry, most people drink water after eating two yolks. After eating so much, he sucked the water out of his body for several days. Then after castrating him, he won't want to go to the toilet, which is good for the wound. It will avoid inflammation, infection and the like, and the survival rate is relatively high, hehe! In ancient times, the occurrence of this disease would make doctors helpless. I think it should be!
