800,000 Border Troops Entered Beijing. Why Did the Emperor Rebel?

Since ancient times, there have been many elite border troops, and they are not allowed to enter the capital without an imperial edict. With 800 frontier troops in hand, they marched into Beijing. To the emperor, they were nothing more than a ragtag group of people who had nothing to worry about; With eight thousand border troops in hand, they marched into Beijing. To the emperor, they were, at best, just a group of rogue bandits of some size and threat; With 80,000 frontier troops in hand, they marched into Beijing. To the emperor, this was a large-scale rebel force that could shake the foundation of the country; However, if 800,000 border troops march to Beijing, it is not the border soldiers who are rebelling, but the emperor! Chen Chuyan's soul traveled through the Dayu Dynasty, became a member of the Dayu Frontier Army, and awakened the [Unlimited Food and Pay] system, earning 1 point per second, which can be exchanged for silver and food. At this time, the Yu Dynasty of Guozuo, which lasted for 279 years, had already turned from prosperity to decline and entered the final years of the decadent dynasty: There is a barbarian invasion outside, and powerful enemies are waiting for you; There are treacherous ministers in power and the emperor is fatuous; Dayu's 800,000-strong frontier army in the important nine-border town has been deducted and owed food and pay by the imperial court for several months. The soldiers are not clothed and fed, and their families are displaced and miserable; Chen Chuyan, who traveled through time, relied on the 86,400 points he received every day to exchange for money and food, allowing the soldiers of the border army to eat well, wear warm clothes, and receive sufficient pay; Within five years, Chen Chuyan had grown step by step from a young captain guarding the Shuobei border to the 'Governor-General' of the nine-border military and political affairs of the nine-border town of the Dayu Dynasty, the general of Pinglu, and the chief military officer; It coincided with the civil strife in the dynasty and when the border troops entered Beijing under the imperial edict, a soldier from the border army put on a yellow robe for Chen Chuyan and asked the emperor why he was rebelling on behalf of the 800,000 frontier troops.
