In the 1990s, Chen Shan returned to Kaoshantun because of a leg injury. To earn food for his blind old mother, he took on the patrol job that no one dared to do, accidentally saving a little tiger cub and activating the "Lord of All Beasts" system — from then on he could understand beast language and command all beasts, with the tiger cub as his guide, the black bear as his guard, and the Goshawk as his high-altitude scout! Others went into the mountains entirely relying on luck, while he strolled with the tiger cub to pick up leftovers all over the mountain; when wolf packs surrounded the village, at a single roar from him, the black bear charged over, and the wolf king was subdued on the spot. The system even repaired his old injuries, allowing him to straighten his back again. For others, guarding the mountain was making a living; for him, guarding the mountain turned the entire Changbai Mountain into his own hunting ground!
