[Beast Transformation + Cautious Cultivation + Sign-In in Hidden Corners + Lighthearted Power Fantasy]
Reborn as a gray field mouse with only three days left to live, Yu Mo binds himself to a Hidden Corner Sign-In System: the narrower and darker the place, the more outrageous the reward!
[Sign in in a gap in the woodshed and receive a top-grade Marrow-Cleansing Fruit!]
[Sign in beneath the floor tiles of the Saintess's bedchamber and score a critical hit: the Taiyin Demon Codex!]
While righteous and demonic factions fight a bloody battle aboveground, Yu Mo nibbles on the earth-vein marrow underground and secretly empties their treasure vaults.
“Go ahead and fight as hard as you like. By the time you're done, the very foundations of this cultivation world will belong to this mouse!”
