Ming Dynasty: I Am the Prince of the Country. Chongzhen Begs Me to Ascend the Throne.

Start by traveling through the Ming Dynasty and become a prince. However, because of his biological mother, he was demoted to the border. Fortunately, the god-level system was awakened. As long as you keep guarding the border, you can get various rewards. And relying on the rewards given by the system, the border is also made unbreakable. But at this moment, Chongzhen sent an urgent message, begging me to drive out the Tartars and return to the imperial city to ascend the throne.
