I Became the Daughter of the Stars

In the seventh year of Emperor Tianwu's reign, the Child of the Stars was born in Xilin Commandery.

Later, the Imperial Preceptor prophesied that the Child of the Stars would overthrow the entire Daxuan Empire. (Here, “overthrow” means destroy the whole of Daxuan.)

Emperor Tianwu sent troops to Xilin Commandery to kill the Child of the Stars.

But the child escaped. Enraged, Emperor Tianwu ordered the execution of every infant born in the empire that year, plunging all of Daxuan into turmoil.

Twenty years later, the Child of the Stars reappears. What kind of storm will follow?
