To hide his ambition, he found a substitute who looked exactly like Bai Yueguang and took her as his concubine, acting affectionate day and night. She followed the current, put on the mask of ignorance, and carefully lurked beside his pillow, weaving a web in secret. He was acting, but he couldn't tell the difference between drama and reality; she was calculating, but she failed to calculate the price of her heartbeat. It wasn't until he put on his yellow robe and tried to wipe away her knowledge that he realized that the source of all the evidence against his political opponents in the Long Case pointed to this trembling "fake". It turns out that he was never the only player in this game of power.
