God has a total of eleven books, and two of them, [Kui] and [Qing], can transform into human forms because of their special abilities. One day, they accidentally knocked over God's bookshelf and were scolded by God, and then asked them to find nine books. Those nine books have half of the power to rule the world. Aoi and Qing, who have the other half, must fight against the ambitions of humans. But humans are not as simple as they thought.
Yin Kui, Mo Qing, they slowly have unnecessary feelings during this journey. Is this a blessing or a curse for them, the right and left hands of God?
