In order to suppress the peasant association, Liu Li, the battalion chief of the joint defense of human life, nicknamed him Yanshitjue, arrested the chairman of the peasant association and released him from the plane. Afterwards, he rewarded Chunhua, the daughter of servant He Feng, and destroyed the love between Chunhua and Mami Black Bull.

Wan Xuan also ordered the black cow to shoot He Feng as a living target, provoking the relationship between He's father and daughter and the black cow. In order to avenge the masses, the armed forces decided to attack Taoyuanbao. Taoyuan Castle is strong and well-defended. It can only be outwitted, not stormed.

Under the cover of underground party member forest, she dispelled Liu Liren's doubts with wit and courage, gained Huei-fang's trust, escaped Wan Xuan's questioning several times, and found out the enemy's situation. She deeply mobilized the masses, turned Chunhua's grief into strength and became her right-hand man; Help He Feng get rid of mental shackles and become a revolutionary soldier; Enlighten and educate the black cow to recognize the gratitude and resentment, and fight back.
