Exiled for the Throne, Now Begging Me to Return

When others transmigrate, they stack buffs; when Zhu Feng transmigrates, he stacks bugs. With the Tatar enemy outside and plague raging inside, this illegitimate prince is packed off to the epidemic zone as a sacrifice. He bullies, loafs, and tries to escape repeatedly, only to be caught. Not until he realizes his father isn't unaware of his uselessness but truly has no one else to rely on, and he can't stand by while the people die, does he risk disaster relief and turn the hellish disaster zone into a paradise. His eight royal brothers fight to the death for the throne in the capital, until one day they suddenly discover that the cannon-fodder fool brother has quietly stood at the pinnacle of power?! Zhu Feng: "Don't look at me, I just want to lie flat. Don't count me in for the succession." Ministers / Royal Brothers / People: "No, you must become emperor!"
