I'm the Crown Prince of Great Tang, and Zhou Jie Is Livestreaming Me!

After transmigrating to the Tang Dynasty, he became Li Chengqian, the Tang crown prince! But as someone well versed in Tang history, Li Chengqian knew all too well what the future held for the dynasty. So he decided to use the knowledge from his previous life to change the Tang Dynasty's fate. Wherever the sun, moon, and stars shine, there lies Tang territory! My name is Zhou Shuyi. I'm a streamer who accidentally transmigrated to the Tang Dynasty and became a princess sent there for a political marriage. And right now, the Tang Dynasty is at war with Goguryeo! Luckily, for some reason, a livestream function suddenly appeared in my mind, letting me interact with my viewers. I thought they could help me get out of this crisis, but none of them believed me! Just as I was about to lose all hope, a dashing man on a white horse, armed with a long spear, suddenly appeared before me as if no one could stand in his way. One man and one spear, enough to take on a million soldiers! Zhou Shuyi and the viewers watching the livestream were all stunned! Since when did the Tang crown prince get so powerful???
