Transmigrated? Life with an Ancient Crown Prince

[One-on-one, both leads are each other's only partners, a future scientific prodigy x a beautiful but tragic ancient prince, upending time and space!]

This world really is one enormous slapdash operation.

How could Heaven possibly let people from two different eras live together!

Xia Denglan stared at the objects in her home that didn't belong to her, her eyes shining. Antiques, antiques! They're all antiques!!

Then she saw a man, and Xia Denglan's jaw dropped. Wait, why is there an ancient person here too?

Yu Feng didn't believe in gods or Buddhas, but he entered a temple.

He knelt down. "Is there any way to keep her here?"

Xia Denglan watched as his tomb was excavated. Inside was a letter:

To my wife, Denglan. May these words find you well...

I want to place this phoenix crown on your head with my own hands.
