When the second prince of the fire tribe, Xin Jue (Jiang Chao), was mysteriously killed during his visit to the Ice Tribe for Ka Suo’s coming-of-age ceremony, the Fire King Huo Yi (Hu Bing) finally has an excuse to start the second war between the Fire Tribe and Ice Tribe. With their parents captured and older siblings killed, the two remaining Ice Princes Ka Suo (Feng Shaofeng) and Ying Kong Shi (Ma Tianyu) escape to the mortal world and seek help from realm guardian Li Luo (Victoria Song) to help obtain ice crystals from six tribes. After the Fire Tribe was defeated with the Deicide Sword, Ka Suo reluctantly battles his brother for the throne, but he wants nothing more than the freedom to be with his lover Li Luo. Ying Kong Shi does everything in his power to take the throne away from Ka Suo, while Yan Da (Zhang Meng), the Fire Princess, is willing to give up everything for Shi. Then, Ka Suo’s loved ones all die off one by one under the conspiracies of Yuan Ji (Yan Yikuan) and Lian Ji (Kim Hee-sun), and he is determined to find the legendary “veiled lotus”. A war between the Ice and Fire Tribe commences again, with Li Tian Jin joining the Fire Tribe to get his revenge on Ka Suo.
