Have you recommended a cultivation novel, but you can't remember the name of the main character?

He only remembered that the main character had to eat a lot of food when he first started cultivating. He was a cleaner in a company. Later, when he went somewhere to cultivate, he absorbed the energy of the volcano. When he returned home, he told his girlfriend about some cultivation…He went to the core of the earth to get something to use to cultivate his armor. After that, he fought with a cultivator…Then he went to the cultivation world…I don't remember anything else ~~~
