MTL - I Built a Territory in Ancient Times

The youngest, silly fourteenth son of the Yan Emperor had reached the age where he should be given a separated territory now. He rejected the wealthy land, neighbouring the capital city, and instead chose the wildest land in the western region— Liangcheng. Everyone shook their heads and sighed. A fool is indeed a fool. If you go to Liangcheng, you will be killed by barbarians in less than three to five years. One year later, the watermelon presented to the Emperor as the tribute from Liangcheng in the west was sweet and crispy. There was no one in the palace who did not love it. Two years later, Liangcheng presented corn as a tribute to the Emperor. The yield was high, and the taste was good. No one in the country could resist liking it. Three years later, Liangcheng defeated the barbarians and presented their prisoners in front of the imperial court. The people of Yan were excited and their morale was greatly boosted. Four years later… Everyone said that the fourteenth prince Mingyu was a fool, while the little fatty Yu, who transmigrated with the golden finger, chuckled. Let’s see how you guys look at this fool build his own territory, then. - Description from Novelupdates
