Great Tang: Summoning Sword and Armor to Crush Li Er's Rebellion

On the eve of the Xuanwu Gate Incident in the Tang Dynasty, a transmigrator became Li Chengdao, the Crown Prince's grandson.

Was Li Er going to wipe out his entire family tomorrow? Was the Tang Dynasty about to undergo a massive upheaval?

No way!

He awakened the National Destiny System. The stronger the Tang Dynasty became, the greater the rewards.

From the start, he summoned Li Chun'gang, the Sword Armor of the Spring and Autumn era!

At the Xuanwu Gate Incident, one sword was enough to suppress everyone!

Li Er: "I'm done for. Who is this old man? He's ruined my grand plan!"

Li Jiancheng: "My son, save me!!!"

At that moment, Li Yuan stood atop Xuanwu Gate.

"Stop fighting. I shall abdicate at once and appoint the Crown Prince's grandson, Li Chengdao, as heir to the throne!"

And so, a great demon king was born.

The Turks: "I'm sick of this. Even his random retainers are Celestial Beings. How are we supposed to fight that?"

Tibet: "We surrender. We beg the Tang Dynasty to take us in. We'll gladly be your lackeys."

Byzantium: "Who could have imagined that such a prosperous empire existed in the East? This is the realm of immortals!"

One day, after the Tang Dynasty unified the world and the growth of its national destiny began to slow, Li Chengdao turned his gaze toward the sea of stars.
