Made a Marquis from the Start: Saving Crown Prince Zhu Biao

Physical transmigration, no System, no golden fingers, no harem: just an ordinary person's journey to another time. Lan Bin, son of Lan Yu, travels alone in the flesh six hundred years into the past. With the one remaining cefixime capsule he brought along, he saves the ailing Ming Crown Prince Zhu Biao! If Zhu Biao survives, will Lan Yu still die? If Zhu Biao survives, will Zhu Di still rebel? If Zhu Biao survives, will the Tumu Crisis still happen? As the wheel of history rolls onward, how can Lan Bin turn the tide alone? He tries making glass, distilling liquor, and refining white sugar: all three golden fingers of a transmigrator fail! He achieves nothing and wins the title of the weakest transmigrator in history. Getting rich is out of the question. If he wants to rise through the ranks, he can only cling tightly to the Crown Prince's leg!
