I, the Fake Prince, Was Demoted to the Wilderness and Took over the World with My Own Hands.

Xiao Yu traveled through time and became the crown prince of the Yan Kingdom. At a time when the country is in ruins and the family is in ruins! Xiao Yu worked hard to invent gunpowder, horseshoes and other artifacts to save the country from fire and water, and also invented modern items such as soap, paper, and printing... Just when the Great Yan Kingdom was developing rapidly and was about to rise again. The emperor said he was a fake prince! Xiao Yu had everything taken away from him, suffered all kinds of torture, and was even exiled three thousand miles into the wilderness! Fortunately, before leaving, he awakened the strongest system. "I hold the jade seal of the country in my hand, step on the dragon of luck, and control the territory of hundreds of millions of miles! I have tens of millions of cavalry and hundreds of millions of soldiers under my command! I suppress the eternal rivers and mountains, and turn my hands to make clouds and rain!" "All the creatures in the world prostrate themselves at my feet." … His Majesty the Emperor: Yu'er, come back quickly! This country was created by you! As long as you are willing, you are my biological son! Prince: Xiao Yu, spare my life, I am willing to serve you! Emperor of other countries: My Chongwu Empire is invincible, but I never dare to shout in front of Xiao Yu.
