Does Cultivating an Immortal Also Require a Part-Time Job?

The unscrupulous author wrote this novel on a whim because of his dream of being a boss. Realistic daily assembly line The system boss protagonist in the book is working part-time "Protagonist: I have a system, I am awesome, I am the best in the world" The author chuckled Just give me a call honestly. Otherwise I will kill you Hahahaha This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
