Shen Qinghuan's life plan has three steps: 1. Become the number one actor in Beijing. 2. Earn enough money to buy a big house and raise a group of actors. 3. Retire, listen to theater, bask in the sun, and spend your old age peacefully. However, before her death, her invisible master grabbed her hand and said with anger: "Qing Huan, our trip to the Liyuan is actually... A hidden stake of the imperial court... You, you want to take over from me, lurk in the enemy camp, and help the country..." Shen Qinghuan: "...?" Master, can you say it again? With my small body, in addition to singing, chanting, fighting, eating, drinking and having fun, you want me to get information? I'm afraid I won't get killed at the beginning! From then on, Shen Qinghuan was forced to start a double life. During the day, she was the star of a crowd-pleased song in Zuixian Tower. Her eyes were dancing and her sleeves were dancing, attracting Prince Wang and Sun Gong to spend huge sums of money. At night, she climbed over walls to listen for secret reports, becoming the sharpest eyes and ears for the army behind enemy lines. But this part-time job is too difficult! The general he was facing was incomprehensible and selfless. Every time we met, he was like interrogating prisoners: "Singing opera singer, where is the information?" Shen Qinghuan's inner OS: Brother, I just finished singing Farewell My Concubine, and my throat is about to smoke. Can you please let me rest for a while! What's even worse is that the target she wants to lurk in - the enemy marshal, is actually her number one theater fan! Marshal: "Miss Qing Huan's Palace of Eternal Life, the lingering sound is really lingering for three days. I wonder when will the girl sing again?" Shen Qing was stealing the battle map. Huan: "..." Help! I just wanted to sing a show quietly, why did I become an undercover agent jumping left and right in front of the enemy coach!
