During the former emperor's reign, there were many battles both in the north and south.
At that time, the loyal and courageous Earl went to the battlefield, followed by Li Dan's elder brother, who was also Li Zishu's father, as the eldest son and the princely heir.
As mentioned earlier, Li Zishu's mother was from Jiangnan, and her family background was not prominent.
Her family was a well-known medical lineage in Jiangnan.
That time, Li's mother also traveled the world with her father, healing and saving lives.
Firstly, it was a family mission to do good deeds, and secondly, to take the younger generation on worldly travels to see the suffering of the world, understand the ailments of different places, and encounter more difficult and complex diseases to improve their skills.
This battle dragged on for several years, with constant back and forth.
There were occasional casualties.
