The Burying Maid Has a Pocket Dimension, Saves the Crown Prince, and Makes Him Her Husband

They are both each other's one and only. She was an all-powerful queen in the 23rd century, but was killed by a villain:

"I've seen the King of Hell!"

"Who sent you here? You still have an unfinished romantic debt from a past life. Hurry and save your Crown Prince!"

"Your Highness, wake up! The King of Hell sent me to save you!"

"What Crown Prince? I'd gladly give up all my wealth and glory to live in seclusion with you!"

The clash of blades shattered the peace: "Your Highness, you cannot abandon all the people of the realm!"

The military command has been seized?

Shen Qiuyi: Don't worry, Your Highness. I have a weapon dimension. I alone can take on a million troops.

Not enough military funds? No problem, I have a gold mine!

After reclaiming all of China, the ministers cried out in unison:

"Your Majesty should take a concubine first. The future of the nation depends on having heirs!"

Shen Qiuyi furrowed her brow...

"From this day forward, my realm shall practice monogamy!"
