System Sign-in, I Actually Became the Empress

(No romantic pairing + time travel + system + strong female lead + daily check-in + invincible)

Reborn as a princess, Qin Xiyue originally wanted to live a carefree life.

Unfortunately, circumstances did not allow it, so they had no choice but to rise up.

Start by signing in and achieving Nirvana Phoenix Body.

The next day, I checked in to practice the cultivation technique.

Sign in on the third day to obtain divine weapons and imperial artifacts.

What??

They actually gave me the Investiture of the Gods, and a pardon for all the gods?!

She originally wanted to be a lazy bum, so how did she become an empress?
