Gatekeeper Rat

Cangyan is an ordinary gray mouse who was born in the gap under the threshold of the ruined temple. His brothers and sisters were all dead, and he survived on half a sweet potato. It has no golden fingers, no system, and it doesn't even understand what cultivation is. It only knows that there is danger outside the threshold, that the whole grain buns are sweet, and that the old man with a bent back comes to put a bowl of paste every day. Later, it swallowed a grain of divine blood dust and opened up its spiritual wisdom. Later, it got into the Cave of Ten Thousand Books and chewed half a volume of "Xuanji Yin". Later, it made friends - a one-eyed black mouse, a mute old man, a girl who sang a requiem, and a monk who had just learned his luck. Later, it lost all its friends and was guarding a door that could not be opened, waiting on the beam for tomorrow's package of coarse grains. Four hundred years of waiting. This is its story. A mouse's long, quiet, and never-confronted history of cultivating immortality.
