Zhang Ziyu transmigrates into a chaotic world with a monster ranch, where he raises monsters and collects their materials.
"Ding! Your hopping vampire has eaten its fill and produced a portion of zombie essence."
"Ding! Your Licker is very pleased with that fat pig and has produced a portion of primal strength."
"Ding! The female ghost is very pleased with your service and has dropped a portion of pure ghost energy."
"Ding! The Tyrant is very pleased with the blood meal you provided and has dropped an equipment blueprint: Tyrant's Gauntlets."
Looking at the monsters being raised in their separate pens, Zhang Ziyu muses, "There's no money in selling raw materials. Looks like I'll have to start a little side business processing them."
