Great Tang: From the Start, I Mistook Li Er for My Father!

Li Mu transmigrated to the Tang dynasty ten years ago. His father left on a business trip thirteen years ago, but a letter arrived ten days ago saying he was coming home.

That year, a severe drought ravaged the land. Starving refugees were everywhere, and bandits ran rampant. Li Er traveled incognito to inspect the realm and learn how the people were faring.

When Li Er was drawn to a waterwheel and knocked on the Li family's door, Li Mu thought his father had returned.
