Now That You Have Become the Prince of the Tang Dynasty, Why Can't You Lie Down?

I camped at Wulao Peak in Lushan Mountain, and when I woke up, I traveled through time and became King Teng of the Tang Dynasty. Did I build Prince Teng's Pavilion? My father, Tang Gaozu! Brother Li Shimin! My nephew Tang Gaozong! Overnight, from cows and horses to Rome, isn't this a wonderful life? But my father is gone, my brother is dead... By nephew? Li Yuanying felt a little unreliable! I wanted to lie down, but in order to live a more comfortable life, I had to make hundreds of millions of changes. This change... Everything in the Tang Dynasty has changed!
