I Am an Immortal of the Tang Dynasty

I transmigrated to the Tang dynasty, where immortals filled the sky, flying on swords, enormous silver waterfalls cascaded down, and talisman puppets roamed...

I gradually realized that civilization had reached its peak thousands of years ago!

The peerless Li Bai was a sword immortal, the world-renowned Wu Meiniang was a saintess of the Demon Cult, and the golden age of the Zhenguan era was actually thanks to immortal cultivation!

Now that I have a Heaven-defying System, I have to do something truly momentous!

I'll start with a modest goal: overthrow the Li Tang dynasty and unite this vast land!
