The Imperial Master Is Dead, Here I Come

Understand that Wang Xianchuan was engaged in scientific research when he was a state minister - he wanted to build a steam engine, but ended up building a "motor that couldn't steam", and he was guillotined. I was a postdoctoral fellow in history and became a seventh grade public speaker. On my first day at work, I heard that my former colleague would be killed in three days. In the prison, Wang Dong held the doctor's hand: "Brother, I walked too fast, please take your time..." Doctor:? ? ? I can't even get into this class!
