Meng Pei's family ran an escort agency. At that time, they were transporting goods to the capital, where they planned to rest for two days before returning.
He was staying not far away and, in a half-asleep state, he heard the noise and got up, following the crowd toward the commotion.
That's when he encountered Song Xin.
In fact, Meng Pei had seen Song Xin before, when he was still a teenager, setting out with his uncles from home for the first time to escort goods. Then, youthful and spirited, he fought back when they were attacked by robbers. After the confrontation, despite his uncles' advice, he chased after the culprits.
As a result, he got separated from his uncles and lost his way, finding himself penniless. It was with great difficulty that he reached the gates of the capital, but he couldn't get in.
With no other choice, he had to find someone to help him enter the city to find his uncles and deliver a message.
