The Immortal Scum's Survival Guide

Su Wenwen was an errand boy in a black shop, and was sold by his bastard father to Yao Guang, a genius disciple of the Evergreen Sect, as a slave. For such a beautiful fairy to become his master, oh no, to become his master should have been a blessing that he had cultivated for several lifetimes. But gradually, he felt that something was very wrong. The master was too kind to him. He could learn the best magic skills at will, and stuff heavenly and earthly treasures into his mouth at will. He is like a young seedling that is carefully cared for. One day it will grow into a big tree, then blossom and bear fruit, and then... Become food for others. However, Su Wen doesn't have the consciousness that food should have. Survival is his eternal mission on the road to immortality!
