Eight Hours of Double Rest to Cultivate Immortality

In the 12 hours of my 24th birthday. I was dumped by my girlfriend who just went to graduate school. My brother and my boss were so dissatisfied that I was laid off. The compensation was only five thousand. My rental house burned down because a kid set off fireworks. 24Th birthday? The quagmire days at 24 are pretty much the same. When I was on the rooftop planning to smoke my last cigarette before entering the factory. An old man came out and offered me an eight-hour job in the cultivating world. I'm not afraid of anything anymore. What is the best fire root in the world of immortality? I gave it to my cute little senior sister on my second day at work! What! There are two worlds of training spells at the beginning! What? It's not just my junior sister who likes me, but also other people? Okay, okay, life is getting better now.
