Space-Time Invasion: Great Tang Is the World's Strongest Line of Defense

In the year 439 of the New Era, aliens sought to exterminate the humans of Hailan Star. But their army of magical beasts could no longer overcome Hailan Star's military might.

So the alien sorcerers opened a space-time gate to Hailan Star three thousand years in the past. If they exterminated every human there, all humans in the present would disappear as well.

"It's all over now. Three thousand years ago, the only weapons humans had were cold weapons. How could they possibly hold back the alien army of magical beasts?"

"Three thousand years ago, the strongest nation was the Tang Dynasty of Huaxia. That means the Tang Dynasty is humanity's strongest line of defense in this war of time-space invasion. But even the Tang army would struggle to hold back the alien army of magical beasts..."

Yet Li Ye, a young man from Earth, transmigrates to the Tang Dynasty ahead of time, becomes a prince of the dynasty, and binds himself to a Card Draw System...
