Revealing himself to be a Dual Knight, Long Hao Chen triumphs in his match within his temple and advances to the finals. But before the grand finals can begin, ranking matches are conducted in each temple to determine the strongest within. During the rankings, Hao Chen is injured, enraging Sheng Cai'er and driving her to seek vengeance for what happened to him. Her actions cause a fight between the Knight Temple and Assassin Temple, only to be subdued after a shocking revelation—that Sheng Cai'er is a Reincarnated Saint. The finals for the Demon Hunting Team Competition begin with the division of the sixty remaining participants into six groups. The top sixteen participants are then further pitted against each other to determine the top three. Each of the top three will be rewarded with a spiritual stove and the right to pick their teammates. In order to become a knight that is capable of defeating the Demon Lord, Long Hao Chen must strive to be first in this competition so he can select the best teammates to give him a fighting chance.

The story takes place between the first and second season, where Rimuru confronts the swirling conspiracies in the Coleus kingdom.

In the vast desert grasslands of northern Novoland, there was a nomadic society that cherished martial arts, believed in the god Pandeng and worshiped heroes. The men there were all hot-blooded and the women were all strong-willed. Their kingdom was called Qingyang. The story is set in Qingyang and depicts the power struggles within the northern nomadic tribes, as well as the grievances between Qingyang and the East Land. As a child, the Qingyang crown prince Lü Guichen was sent to live with the Yanzhen Tribe by the Great Lord. After the tribe rebelled, Lü Guichen was brought back to Beidu city. However, his older brothers did not value this young and weak crown prince, instead focusing solely on competing against each other for the throne's succession. Yet, after experiencing the baptism of war and the ups and downs of life, Lü Guichen, with his gentle personality, gradually matured and gained strength amidst his older brothers' power struggles... During that time, the royal family of the East Lands was in decline, and several feudal states had emerged. The Great Lord of Qingyang sought to use an alliance with the Xia Tang State to achieve his ambition of dominating the East. As a result, Lü Guichen was sent as a hostage to Xia Tang. It was there that he met the unruly Tianqu warrior, Jiye, and was drawn to Jiye's tenacious and unyielding spirit, eventually becoming close friends. This is the story of the young Zhaowu Duke and the young Yulie King of the Xie Dynasty-to-be.
