Is It Too Much for Me to Become a Prince by Making Guns and Cannons?

Military expert Zhao Chen died suddenly and traveled through time, becoming the most disliked ninth prince of the Great Yan Dynasty. Others laughed at him as a waste, but he devoted himself to drawing blueprints, smelting steel, and making guns, cannons, and tanks. When the enemy's cavalry pressed on the border, he led an army of tanks and opened an era. After five years of sweeping through six kingdoms, he ascended to the position of crown prince with his hard-core military exploits, and even stood side by side with the prime minister's daughter Yu Yao. On the day when the new emperor ascended the throne, he looked down at the mountains and rivers thousands of miles away. In this prosperous age, we should protect it with guns and cannons.
