Shi Lin, a lonely, elderly forest ranger, is reborn in 1984 at the age of 21. Right from the start, he accidentally disturbs a hornet's nest and unexpectedly activates the Beast Servant System. He contracts hornets as beast servants, allowing them to track down every beehive hidden across the mountains! As their master, Shi Lin reluctantly follows the hornets around to collect the honey. He contracts a sable as a beast servant, and suddenly there are more wild rabbits, pheasants, and cuckoos than he could ever eat. He contracts a giant bear, and the entire mountain becomes his own backyard! In his previous life, he was so poor that he couldn't afford to marry. In this life, however, aunts and older women are competing to introduce him to potential brides, leaving him with quite a headache.
