Chongsong year.
The Western Yi invaded the Qi and Jin Dynasties on a large scale.
The war was about to begin, and Weiyi general Su Shi took command of the expedition. On the way, he was suddenly attacked by rebels and was seriously injured. In order to boost the morale of the army, Su Shi's sister Su Hui concealed Su Shi's serious injury, then pretended to be Su Shi and conquered the barbarians on behalf of her brother. During the battle to pacify the captives, when the Qi army was on the verge of victory, they were seriously injured by a spy in the army. He died over time and unfortunately died in battle. Later, Tao Hua, Jiang Mei and others arrived in time to turn the tide and finally drove the barbarians out of Qi and Jin.
The battle was over, Qi and Jin narrowly won.
Soon after the war broke out, the whole country mourned Su Hui's death.
The new emperor Chongsong announced to the world that he granted Su Shi's sister Su Hui the title of Princess Yunhuan in order to mourn the deceased.
When Su Shi learned that his sister had died in the battle, he was so sad that he was seriously injured and fell into a coma. He had to recuperate for a long time before recovering from his injuries.
In the second year of Chongsong.
Su Shi asked Emperor Chongsong to resign as general, but Chongsong repeatedly persuaded Su Shi to stay. Soon, Su Shi reluctantly asked Emperor Chongsong to give up martial arts and follow literature, but he no longer wore military armor and held a bloody blade.
