I Am The God Of Martial Arts. What Happened To The Emperor's Brother Who Was Given The Death Palm?

Carrying a plug-in and traveling through time to become an Emperor, Chen Xun wanted to stay in peace for a while after he managed the country in an orderly manner. However, he did not expect that the civil and military officials of the entire dynasty thought he was fatuous, and the emperor's brother who was in charge of the army even wanted to usurp the throne.
Chen Xun didn't bother to explain, and directly ordered the death of the emperor's younger brother who commanded 600,000 troops. The whole country was shocked!
When 600,000 troops came to the city, Chen Xun stood up straight and stretched.
"I originally wanted to get along with you as an emperor, but what I got in exchange was rebellion. Then I stopped pretending and showed my cards. I am invincible, you can do whatever you want!"
...
Many years later, Chen Xungao sat on the nine heavens, overlooking the immortals below, and let out a long sigh: "Oh, to be honest, I really just wanted to lie down. You have really hurt me!"
