Time Travel: Guys, Take Me to Fly

"Doctor of Finance" Shi Xing accidentally traveled to a magical world: here history reappeared, the five great powers of Qin, Han, Tang, Song, and Ming came to dominate the human world, and the "four emperors and one king" pattern lasted for thousands of years; here demons are rampant, including Baron Nash, Black Mountain Old Demon, Nine-tailed Demon Fox, Yamata no Orochi... Seven dark restricted areas dominate one side. (PS: The Qing Dynasty died)
