He was an orphan after both of his parents died before his eyes when he was still a teenager. Fortunately, the emperor was willing to let him live under his care after he had no adults to rely on.
The emperor entrusted him with several tasks at that time, and it started with the task of becoming the prince's bodyguard. The prince was originally a cheerful and talented child, but he became more gloomy after suffering from a mysterious illness. At that time, he was given another task: to be the prince's friend and restore the prince's motivation to live well.
It was actually not an easy task, but he managed to do his job perfectly. Gradually, the prince returned to his old self, and the emperor rewarded him by giving him a position in the army. As a soldier, he was very talented, and he even became a general at a fairly young age.
