Who Told You to Raise Pigs with the More Children, More Blessings System?

[Raise pigs to become a saint + more children, more blessings + hand them over to the sect + mecha spiritual roots + if they won't give me pigs, I'll take them] Zhou Xingxing transmigrated to a world of immortal cultivation and obtained a multi-child System. Unfortunately, Zhou Xingxing was a lowly pig-farming servant and couldn't find a cultivation partner. On top of that, he had been selected for the Investiture of the Gods List, and in ten years he would have to enter the battlefield and compete against the geniuses of the Myriad Worlds. With no other choice, Zhou Xingxing decided to transfer his traits to Bajie, the big fat pig he raised. It shouldn't have worked, but luckily he exploited a bug in the System and successfully transferred the traits. Although the rewards for the traits were halved after the transfer, pigs could have lots of piglets! He also handed himself and his big fat pig over to the sect. With the sect's help, rewards poured in, and he harvested so much from the System that it was left in tears! [Ding! Reward: Aptitude-Enhancing Pill. Reward: Bloodline-Enhancing Pill. Reward: One hundred years of cultivation. Charm increased by 100. Reward: Piggy Heaven-and-Earth Fart Technique.] [Ding! Piglets exceed one thousand, breaking the System record. Host rewarded with a premium mutated mecha spiritual root. Big Fat Pig rewarded with a trace of the Heavenly Canopy Divine Beast's bloodline.] [Ding, ding, ding...] The System cried itself unconscious in the restroom. From then on, Zhou Xingxing had only one goal in life: find a wife for his Bajie. Saintess, please wait. Name your price! Hey, hey, hey, Saintess, what are you doing? It's not me and you. My spirit beast is supposed to pair up with your spirit beast. Miss, please behave yourself. I'm an honorable man. For the sake of my Bajie, I'll endure... Ten years later, the Investiture of the Gods battlefield opened, and the geniuses of the Myriad Worlds descended. Where were all those geniuses they promised? How come not a single one could put up a fight?
