You Agreed to Be My Substitute, Why Did You Ascend the Throne?

​Zhao Zheng traveled through time and became the substitute for the Prince of Daxia. ​​But he accidentally activated the Dragon Swallowing Way! As long as you are rewarded by the king, promoted to a court official position, and receive support from the people, you can transform Daxia's dragon-qi national destiny into supreme cultivation! ​Being appointed an imperial envoy? Obtain the true dragon's purple energy and go straight to the master's realm! Take control of the household department? Hang up every day to absorb the national luck and upgrade while lying down! Reclaim the border? With the faith of all peoples gathered together and the supreme energy of Kowloon, they are invincible in the world! "Your Highness has the style of Taizu, and is truly the master of the Great Xia Zhongxing!" "Is it true that the imperial court is weak and can be bullied? The prince brought 30,000 cavalry and razed our thousand-year-old mountain gate to the ground!" "I, the nomadic nation of Dajin, were slaughtered as cattle and sheep today!" "I just asked you to block the bullet for me, why do you ascend the throne and proclaim yourself emperor?!" The prince was furious. Zhao Zhengduan was sitting on the dragon chair, condescending, and smiled calmly: "The civil and military officials of the entire dynasty and all the people in the world only recognize me. As for you? Which road is it?"
