On the first day after Su Wanyue, a water conservancy engineer, was deposed in the cold palace, the tyrant Xiao Heng pinched her chin and mocked her: "A despicable useless person is only worthy of eternal life to cleanse my chamber pot."
Faced with the malicious intentions of the palace and the scarce water source, she silently used her professional knowledge to renovate dry wells and design waterwheels, and finally let the clear spring flow into the cold palace, freeing the tired palace maids from their hard work.
The news reached the imperial court, and the tyrant broke into the cold palace late at night and imprisoned her in his arms: "Who allowed you to touch my water veins?"
He forcibly named her the "exclusive living spring eye" and imprisoned her in the center of the crystal palace made of fine gold. He had to drink the blood of her fingertips every night to stay alive: "Without you, this country would be meaningless."
Su Wanyue's fingertips were bleeding and her eyes were calm: "Does Your Majesty know that the imprisoned 'spring' will eventually become corrupted?"
Xiao Heng obsessively kissed away the blood on her wrist: "Then let us kill each other until we are dry and fall into the abyss together."
