Lin Yue'e, the queen of shadow puppetry, uses light and shadow as advice, predicting what will happen in the next three days. The prince fell off his horse and escaped, and the flames in the granary were extinguished early, but he was denounced by the emperor as a witchcraft. When the shadow puppet staged the bloodbath of the emperor, she cut off the assassin's leg, the shadow bit back the limp, and hid the last half of the fragment. The prince pressed down on the afterimage, and the assassin's mask fell off, just like the cracks in the shadow puppet. The emperor lifted up the lame queen, and the burned shadow puppet finally became a bond of mutual trust between the king and his ministers. Light and shadow are blades, and silk threads are strings, affecting nine levels of people's hearts.
