This King Is Only One Year Old, You Want Me to Counterattack and Become Emperor?

When he woke up, Lu Xuan traveled through the ancient dynasty and became the second son of a powerful official, King Beining. Unexpectedly, Lu Xuan was poisoned in his previous life and was left alone for half his life. He unexpectedly awakened the counterattack and proclaimed emperor system. Isn't this ridiculous? "Holy crap, what's wrong with a system that came to me when I was in my thirties and was about to die? But now I'm reborn, but I've just turned one year old. Isn't this a big deal?" Lu Xuan shook his head, and then broke the jar. Unexpectedly, it turned out to be a system bug. He replaced the shotgun with a cannon, and then planned to usurp the throne. What happened to one year old? Is it too late to rebel and become emperor at the age of one?
