Zhao Kuo of Wuchang was from Qi. He studied the Way with Yong Shi Gong of Wu. In the third year, asked to return. The Gong said: “The disciple’s Way is not yet ready; how can return be appropriate?” He then expelled him. On reaching Qi he had just stopped for a rest when a clerk resting alongside him, thinking him a criminal, was about to seize him. Kuo went more than a hundred paces, then transformed into a blue deer. The clerk pursued him. He ran into a narrow alley. Feeling extremely tired, he squatted down for a rest. The clerk spotted him and resumed the chase. He transformed again, becoming a white tiger, and fled in haste. Seeing a pile of manure, he entered it, changing into a mouse. The clerk spoke in sudden realization: “This man can change shape! This must be him!” He then grabbed the mouse and tied it up. Then, expanding and returning to his shape, he was committed to prison, and sentenced to execution and exposure in the town. When Yong Shi Gong heard of this, he sighed: “This is my fault.” He thus went to see the Prince of Qi, and said: “I hear the great realm has a convict who is able to change shape.” The prince then summoned Guo, and commanded his troops to surround him. Guo attempted to transform into a mouse. The Gong immediately changed into an owl, grabbing the mouse and departing, then flying into the clouds.
