Xiaolong grew up in the mountains and studied martial arts with Master (Huang Yifei). One day, master realized that Xiaolong had lived alone since childhood and knew nothing about the world, so he asked him to go down the mountain, understand the world and do something meaningful.

Xiaolong was ordered by the teacher to go down the mountain. When he first arrived in the city, he felt like a country bumpkin. Everything was fresh, but he found the interpersonal relationship in the city alienated and treated his enthusiasm coldly. Xiaolong often jokes, only to know that it is not easy to do something meaningful, and he is very discouraged.

Cheng Fei's nickname "Gefei" is also called "Niu Marufei" (Lu Jianming). His father is the famous king of Niuwan, and he created a kind of "Super Niuwan" with excellent taste. However, the secret recipe was lost in Gefei's hands, and Gefei's beef pill stall business was extremely poor. His daughter Miner (Zhen Xi) advised him to change careers, but Ge Fei insisted on changing careers. He studied the formula of the lost beef balls all day, ignoring his family.

Xiaolong passed by Gefei's beef ball stand, just as Gefei threw the unqualified beef balls out of the store. Xiaolong, who grew up in the mountains, has never tasted such delicious food. It happened that Brother Fei's assistant resigned because he couldn't get paid. Xiaolong thought it was meaningful to make delicious beef balls, and offered to help him make them for free, only asking for two meals a night. Brother Fei took Xiaolong home and taught him how to make cow pills. Xiaolong quarreled as soon as he saw Gefei's father and daughter, and was determined to make up with Gefei's father and daughter.

At this time, the International Food Group is trying to buy Niuwan stalls and nearby shops, transform them into a large bar city, and entrust the real estate developer Jin Brothers to buy them on their behalf. Although the business is extremely poor, Fei Ge is still unwilling to give up his ancestral business, and firmly believes that one day he can study the formula of Niuwan and restore his father's reputation as King Niuwan. The Kim brothers tried their best to finally make Brother Fei bow. Xiaolong was quite disappointed. He vented all his grievances on the beef and slapped it with his cold palm. Who knows this is the secret recipe of Niuwan lost. The next day, Cai Nan (Liu Xixian), a famous gourmet, passed by the Niuwan stall and tasted the Niuwan made by Xiaolong with kung fu. He was amazed at the reappearance of Niuwan, and named it "Playing Niuwan with Ice and Fire", which was widely publicized on TV. Niumaru Downton R has a prosperous business and is overwhelmed every day. Mins came back to help, and the father and daughter made up. Xiaolong was very pleased and finally did something meaningful.

Brother Jin discovered that the stall of Niuwan came back to life because Xiaolong used kung fu to beat beef and secretly poisoned the seasoning of Niuwan. Xiaolong was poisoned by playing beef with qigong. Boss Jin also brought hooligans to smash the field, and Xiaolong was poisoned, just as Master Xiaolong went down the mountain to fight off the hooligans and drive away the poison for Xiaolong. Niu Ma Rufei found that Xiaolong's master was A Gui, his father's great disciple.
