In the winter of the 22nd year of Hongwu, Prince Zhu Biao patrolled the border and angrily investigated the misdeeds of the vassal king. The King of Qin worked hard for the people and the King of Jin was murderous. Two consecutive disappointments made him exhausted mentally and physically. Arriving in Datong, the fiefdom of King Zhu Gui, during a snowy and windy journey, he disguised himself as a businessman and made an unannounced visit. However, he saw that the streets were free of frostbite and the people were avoiding outsiders. He mistakenly thought it was another farce to whitewash peace. The moment you step into the inn, a billowing heat wave hits your face. It turns out that Zhu Gui's collective heating magic method is hidden. The steel giant spewing white smoke in the snow curtain turns out to be a steam engine that can drive heating and drain the water from waste mines! The shopkeeper's eloquent story shocked him even more: He collected waste mines and turned them into gold mountains on behalf of the king, but did not compete with the people for profit. He had long been regarded as a "living Bodhisattva" by the people of Datong. From full of worry to dumbfounded, this young prince who was underestimated actually created unparalleled political virtues in the bitter cold border with wisdom beyond his time. Let's see how Zhu Biao uncovers the unparalleled work of the king, and witness the beginning of the most amazing legend of the vassal king in the Ming Dynasty!
