This drama describes how the declining king Sun Tiemuzhen overcame many difficulties, revived his family business and became a great hero in unifying Mongolia. "Genghis Khan" Temujin of Qiu Yan was hunted down by his enemies, but was saved by Chi Laowen and He Jinkui.
After Temujin escaped from danger, he found his own clan and reorganized his home with his brother Cesar, vowing to revive the beggars. The enemy attacked Temujin one after another and took his wife's Kyle Polo post. Temujin had to help his sworn brother Jamukha and his adoptive father to save his wife. After this battle, Temujin gained momentum and became more and more powerful, and he was called "Three Outstanding Prairie Men" together with Jamukha and Bieli.
Jamukha was very interested in Kyle Polo's post and tried his best to approach it, but Kyle Polo's post was faithful. Jamukha held a grudge against Temujin from then on. Sang Kun, the son of Bieli, fell in love with Temujin and proposed to him. Temujin refused to get married. It turns out that Temujin has been secretly in love with Temujin, and Marco Polo thinks Temujin is really pure, which makes them come together.
Sang Kun was unwilling and often vilified Temujin in front of his father. On the other hand, Jamukha's brother was killed by Temujin, and Jamukha made enemies, vowing to destroy Temujin. The "Three Heroes of the Grassland" launched a fierce struggle from then on.
