Li Guihe, an illegitimate son of the Duke of Dingguo's household, has been confined to a remote courtyard in his wheelchair ever since his mother died when he was three. For thirteen years, he has secretly woven a web of spies, gaining control over the capital's intelligence network. Amid the struggle for the throne, he turns his enemies' strength against them and sends his mother's murderers to hell one by one. But after taking his revenge, he chooses to let it all go and retire amid the rivers and mountains of Jiangnan. This is the legend of a cripple who rose from the shallows, soared above the clouds, and ultimately returned to the simple comforts of ordinary life.
