Reincarnated Escort Warrior

My dream is to become an escort warrior that rides on a cool horse and transports goods. But Ive got a limp leg and Im unable to learn decent martial arts. Ive lived as a porter working odd jobs for the entirety of my life. Until I died because of the mountain bandits that I met during an escort mission.

But

I became the fourth young master, Lee Jungryong?!

When I died and woke up, I was reborn as the Heavenly Dragon Escort Agencys infamous good-for-nothing youngest son.

The weakling, Lee Jungryong, will become the best escort warrior in this life!
