The background of the story is that during the period of the Republic of China, warlords scuffled and Japanese troops attacked. At that time, China was in chaos. At this time of life and death, a group of hot-blooded children stood up and bravely fought against the invaders, and the heroine Fang Ya was one of them.

Wu Baotong, the male leader, was a great traitor and a traitor with outstanding ability. He made great contributions to the Japanese nation by using his excellent military talents and became the key protection object of the Japanese nation.

Fang Ya is very beautiful, her beauty is her biggest weapon, so the organization gave her a dangerous task - to assassinate Wu Baotong.

Fang Yasheng had a rough life. He was wandering in troubled times. When he nearly starved to death, he was saved by a group of kind-hearted students. They were friendly and kind-hearted. They gave her food and water and took her to escape alone. Unfortunately, they met the Japanese army. The students hid her in the forest, but they died because they didn't have time to escape, She watched that group of innocent and kind-hearted students were treated as playthings in the hands of the Japanese army. The male students were tortured and killed, and the female students were taken away to become comfort women after being insulted. She looked at their desperate eyes, cried in pain, and could not help rushing out. It was one of the male students who tried to stop her with her eyes.

She didn't have the weapon of interest, and she didn't have the martial arts of peerless. Rushing out was just a plaything for the Japanese army. Life would be worse than death, let alone revenge. So she could only look at it stiffly, let her tears flow down her cheeks, but she didn't dare to make a sound. She wanted to see these people's atrocities in her eyes, engrave them in her bones, and revenge her!

She didn't dare to move until the Japanese army left. When it was almost dark, a group of people came to collect the corpses of their compatriots and found her. These people were as kind as the students. They gave her hot water and food and took care of her. They asked her to take care of herself after she came to the city. By this time, she already understood what they did, They are a brave team to fight against the aggressors. In order to save the Chinese people from the abyss, they shed their blood without regret.

Fang Ya decided to stay. Before performing the task, she organized a three-month strict special training, taught her how to use Morse code to transmit information, taught her how to use life-saving weapons and some martial arts, and even began to learn some etiquette and dancing of aristocratic ladies in order to cater to her role.

The organization inquired that Wu Baotong once had a childhood sweetheart's neighbor sister. When they were young, they studied in a school and had a good relationship. Later, the neighbor's sister moved, and they had no contact with each other. Therefore, Fang Ya wanted to approach Wu Baotong in such an identity to gain trust and ensure the success of the assassination.

Because Wu Baotong was suspicious, Fang Ya wanted to use this identity, but she couldn't bring it up by herself. Instead, she wanted to let Wu Baotong guess by herself through details. In order to let them meet by chance, a special Comrade inquired about Wu Baotong's itinerary. Because he was the key protection object, he was restricted from freedom. He could only come out between 1:00 and 3:00 every afternoon, And he likes to listen to plays, and every day he goes to Liyuan to sit down.

Because singing can't be learned overnight, Fang Ya can't sing to attract her, so she becomes a tea serving boy in the theater.

She disguised herself as a man and splashed water on Wu Baotong's body when she served tea to attract the attention of the other party. Unexpectedly, people just waved her down and didn't care.
