In the Medicine House of the Cold Palace, Shen Ruoyan, an orphaned imperial doctor, practiced "happy and sad" to spit out secret pungents, and "forgetful of sorrow" to wipe away the past. However, the elixir is full of tricks. It can control people for a while, but it can also eat away at yourself. The Queen Mother wanted to use her hands to weave a web of power, but she used "half truths and half lies" as a chess piece to arouse the Emperor's suspicion. Her pulse condition gradually became disordered, and her drug addiction became like silk. She struggled between control and backlash. Finally, with the kindness of a doctor, she turned the strange pill into a good way to calm the nerves and break the nine deep barriers.
