The legend of the origin of cancer

Hercules was the son of Zeus and alcmene, a folk woman. Foreigners' names are hard to remember. Anyway, Zeus and a strange woman gave birth to a son Xiao Hai. He was born a thorn in Zeus' wife Hera. Hera is really not easy. She has a playboy husband.

So Hera sent two poisonous snakes to hurt Hercules who was sleeping in the cradle. Hercules was indeed the son of God, and immediately killed two poisonous snakes. Hera did not give up the persecution of Hercules. When Hercules grew up, Hera drove him crazy, killed his wife in madness and threw the child into the fire to burn.

Hercules went through twelve very dangerous adventures to atone for his sins. The second of the twelve adventures, I conquered a nine-headed water snake named Xu Dela in Lela swamp.

Every time a nine-headed water snake breaks, two new heads grow immediately, one is long and the other is long. This is a mathematical problem. Here comes the problem. If it breaks 100, how many heads will there be? Please count slowly first. Finally, Hercules found a way to burn the wound of the water snake so that it wouldn't grow a new head. The water snake was wiped out by Hercules.

Hera sent a big crab to help the water snake in the battle with it. The crab caught Hercules' foot, but Hercules trampled him to death at once. Hera lifted the big crab to the sky, that is, cancer, in memory of this huge crab.
