A trading analyst, due to an accident, is transported to the Wanli era of the Ming Dynasty, becoming the live-in son-in-law of a major tooth merchant.

He originally thought he could, like the protagonists in time-travel novels, make a name for himself in ancient times, amass wealth rivaling nations, and have wives and concubines in abundance.

That was until he met the Wanli Emperor—the very same famous one from the Annals of Wanli...

“Your Majesty, about the commoner’s commission...?”

“Don’t worry, you won’t be shortchanged. I’ll have the Ministry of Revenue send it to you right away.”

“Your Majesty, you previously asked me to empty out the national treasury to fill the inner palace. Now there’s nothing left in the treasury but rat droppings!”

“In that case, I’ll contract the treasury out to you again.”

“...Your Majesty, may this commoner speak frankly?”

“Go ahead, speak freely.”

“MMP!”
