From a Casual Cultivator to the Heavenly Demon Lord

Fang Zheng traveled through the Heavenly Demon Realm and became a casual cultivator in Lingguifang City. His parents disappeared, his family property was devoured, and his only valuable fish pond was taken away. He was so impoverished that he couldn't even pay the rent. Fortunately, with the help of the exotic treasure [Demon Refining Pot], if you put the corpse of the demon into the pot, you can get the spirit liquid, increase your mana, and extend your lifespan. I thought that the [Demon Refining Pot] could only refine demons, until Fang Zheng accidentally took in a Qi training disciple. Fang Zheng not only received a more pure spiritual liquid tempered body, but also obtained the remaining life span of this disciple. The door to the new world is completely opened. During the day, Fang was a simple and honest fish seller. At night, he transformed into a night murderer who hunted for talented people. Thousands of years later, looking back, Fang Zheng has become a giant of demons who lives as long as Tianqi. In order to live forever, Fang Zheng set his sights on the entire world of demons. "The sun and the moon spin in the hand, and the marrow of yin and yang is refined in the pot." "Kill all the demons in heaven to gain eternal life, refine demons and humans to refine heaven!"
