A fun little story inspired by a random idea. The writing might be a bit messy.
An accident gave Li Shimin an unbeatable trump card from the Sea of Chaos, allowing him to defeat the king of Goguryeo without lifting a finger. After that, Li Shimin couldn't stop exploiting the Sea of Chaos. It was so vast, so what was wrong with taking a few trump cards for himself? The more he took, the happier he got. But could someone tell him why he had to pay them back? Heavens, how much merit could his mighty Tang dynasty possibly have? Wait, no. I seem to recall a monk went traveling west and came back with a mountain of merit. Fine, tell that monk he doesn't need to go. I'll go myself.
