The King of Hell Is a Cancer Patient

In order to survive, I stole all the ocean sediment and developed targeted cancer cell removal technology. In order to control it, I crystallized my emotional energy, gathered my souls into soldiers, and built an underworld with my own hands. I put on the mask and said to the first batch of awakened souls: "The underworld is in civil strife and the space is shrinking. From now on, reforms will be carried out." I use a modern corporate system to manage the underworld, use emotional crystallization to issue currency, and organize a team of scientists to work on life extension and cultivation systems.
