I’m Terminally Ill, So What If I Lead the Tang Dynasty Astray?

I transmigrated into the Tang dynasty as Li Kuan, the second prince who was destined to die young. From the start, I was terminally ill and on the verge of death, yet I somehow bound myself to the [Shameless Life-Extension System]!

Stir up trouble, make people lose their cool, overturn history, and I can replenish my life indefinitely!

Li Kuan simply gives up trying: I’m coughing my lungs out anyway, so what’s wrong with being a little shameless?

When Crown Prince Li Chengqian, driven into depression by rotten Confucian scholars’ abuse, comes into view, Li Kuan hands him a sack while coughing up blood:

“Big Brother, forget your manners. Put that old scholar in the sack and take your frustrations out on him!”

The next day, the Crown Prince’s tutor shows up at court with a bruised and swollen face, and the whole Tang dynasty goes completely off the rails.

Li Chengqian awakens: dignity belongs to whoever has the stronger fists. Father, I want to hold military exercises at Xuanwu Gate!

Li Tai follows right behind him: Blowing up Goguryeo sounds way better than fighting for the throne. I’m with Second Brother: let’s give them a physical send-off!

Years later, Li Shimin looks at the Crown Prince, overflowing with martial spirit and shouting “Charge!” every day, then glances at Li Kuan, who is coughing up blood and going mad while the entire court has to humor him. He loses it on the spot.

“You rebellious brat! I told you to teach the Crown Prince to read, and you taught him to rebel against me?!”

Li Kuan coughs out a laugh. “Your Majesty, I just want to live a few more years!”
