Juntian founded the country for three hundred years, and it was passed down to Emperor Qi Kun. Although he was the co-lord of the world, his country's power was gradually declining, and his control over the subordinate states was not as good as before. Among the vassal states named "Big Dipper", Tianquan, Tianxuan, Tianshu, and Tianji were the strongest.
Tianquan is located in the western border and is rich in resources. He was the first to claim the throne. He relied on the natural dangers of Yuzhao Mountain and rarely interacted with other countries. Tianshu was located in the northern border and was rich in fine horses and fine iron. The people of Shu were good at dexterity and construction skills. After establishing themselves, they annexed and connected with other countries. Kaiyang, a small vassal state in the southeast; Tianxuan, a small vassal state in the southwest, has strong horses and strong people. After the new king came to the throne, he actively opened the reins and expanded the soil; Tianji, a small vassal state in the southeast, followed witchcraft rituals and focused on farming. Although he has not yet become the king, he has annexed another small vassal state, Yuheng.
In the 329th year of the Juntian calendar, Tianxuan launched an army to attack Yaoguang, a state directly under Juntian's minting. Emperor Qikun was angry and sent troops to surround Tianxuan. The army of hundreds of thousands was overwhelming, but he was assassinated on the eve of the war. From then on, the world In the chaos, the four major vassal states are ready to move, and the Yinsu Kingdom, whose true appearance is difficult for the world to see, is also waiting for the opportunity. The assassins join forces and choose their master for fame, profit, self, love, kindness, and the righteousness of the country.
