In the tenth year of Shaoxing (1140), the Jin Kingdom tore up the peace treaty and invaded the south on a large scale. Shucheng County on Huaixi Road was raided by Jinqi. Seventeen-year-old Shen Ji went out and escaped, but when he returned, he found that his mother had fallen into a well, and his grandmother and aunt had been brutally killed by swords. Overnight, he went from being a pharmacy apprentice to a homeless orphan.
Shen Ji fled to Lu'an City with his uncle Shen Yaozi who was lucky enough to survive, only to find that the Jin people had camped outside the city and were not attacking, waiting for reinforcements. Zhou Tong, the captain of Lu'an County, was determined to defend the city. Shen Ji took the initiative to avenge his family and asked Ying to leave the city to lure the enemy. This was the beginning of a revenge with great disparity in power.
However, Shen Ji soon discovered that he had to face more than just the Jin soldiers outside the city. In troubled times, officers and soldiers, bandits, gangs, and anti-Jin rebels all had their own agendas. Some took advantage of the situation to rob, some took the opportunity to cause trouble, and some secretly collaborated with the enemy. The blunt knife in his hand could not kill a few people, but it could split open a world he had never seen before.
