Wang Jiao passed through the Tang Dynasty, and it was the Zhenguan period "three hundred years of Zhenguan? Clam?" this is a Tang Dynasty that has been smashed by the predecessors of the piercers.

Words are daggers, knives, swords, and occasionally fascia guns, buzzing, buzzing, buzzing... PS: the world outlook of engineering students in the Tang Dynasty.
