Great Tang: Imprisoning Li Er for Ten Days and Nights from the Start

He transmigrates to the Tang Dynasty with an Inventor System and becomes Crown Prince Li Chengqian.

Bicycles, roller skates, juicers, shampoo: all sorts of inventions roll out of his laboratory and into the everyday lives of the people of the Tang Dynasty.

Li Chengqian's laboratory also becomes the only forbidden place in the imperial palace. No one is allowed inside except Li Chengqian himself, not even Li Shimin or Empress Zhangsun!

In the second year of the Zhenguan era, Li Chengqian leaves Chang'an in search of materials.

Before departing, he repeatedly warns Li Shimin not to let anyone break into the laboratory.

But after several ministers egg him on, Li Shimin can no longer resist his curiosity. He sneaks over to Li Chengqian's laboratory with Cheng Yaojin and a few others.

Soon, a cry rings throughout the entire Tang imperial palace:

"Someone, come quick! His Majesty has been captured by a monster!"
