I'm the Heir of the Duke Who Guards the Nation, and You Want Me to Make a Good-for-Nothing Comeback?

[You've transmigrated. In this life, you were born into poverty with an inferior physique. With no other way out, you could only sell yourself into servitude at the Duke of Zhenguo's residence.

You're now over twenty, yet you've achieved nothing. You're stuck doing the lowest-level chores, spending every day feeding horses and chopping wood. Are you really content with that? As a good-for-nothing, don't you want to turn your life around?]

Good news: I've transmigrated.

Bad news: The System is broken.

Lu Yuan transmigrates into the heir of the Duke of Zhenguo in the Great Yu Dynasty. At just eighteen, he has already reached the Marrow-Refining Stage of martial arts.

The Duke of Zhenguo's family has guarded the northwest for generations, commanding the military and government of thirteen provinces, with an army of over two hundred thousand at its disposal.

What does the Marrow-Refining Stage mean? It qualifies you to serve as a battalion commander in the army.

For an ordinary martial artist, breaking through to Marrow Refining before the age of forty is already an extraordinary feat.

Anyone who breaks through before thirty is considered to have limitless potential.

And you want me to turn from a good-for-nothing into a success?

Until...

[Zhong Xiyu of the Embroidered Uniform Guard will investigate a case on Jia Shen Street tonight and be ambushed on the way]

[Why not follow along, then strike at the right moment and put on a grand show?]

This System may be crazy, but it seems to have its uses!
