Li Zhao transmigrates into the Tang dynasty during the Shangyuan era and becomes the crown prince.
But! Unfortunately, this crown prince is Wu Zetian's son.
But! Fortunately, the protagonist awakens a System as well.
But! Who would have guessed the System would be called the “Ultimate Slacker System,” encouraging him to slack off?!
But! Luckily, this System can evolve.
But! What on earth is the “Ultimate Rat Race System”?!
What's more, the protagonist discovers that the System has even changed the course of history just to give him missions. A rebellion that should never have happened breaks out ahead of schedule, and from that day on, the protagonist never knows peace again…
The starting point is quite novel, and the words are very interesting, but it's a bit short, isn't it?
