Sam, a snake who recently transmigrated with a system, faces immediate danger when his parents present his tiny beast core to Lord Redfang. They call him useless; Sam insists he'll die without it. Lord Redfang scorns the core, accepts a Bloodspirit Fruit, and orders a hunt in three days to collect wolf beast cores. Sam's system detects critical life signs, activates automatic devour, consuming bones and rotten flesh and gaining one evolution point. He switches to manual mode, devours common bones, and his beast core begins repairing. He has three days to recover before the hunt.
