- Description from novelbuddy

Wei Suo, a low level cultivator from the Spirit Peak City was scammed in a transaction. He ended up purchasing a damaged low level magical treasure. However, this worthless damaged magical treasure had an artifact spirit that already lived for several tens of thousands of years… On top of that, compared to several tens of thousands of years ago, many of the rare and sparse things were abundant now.

The dominant forensic doctor who traveled back in time to the era of the Great Tang's Zhenguan reign, became a distinguished family's abandoned girl.

Hit by a truck as a young man, after winning God’s ultimate lottery prize, I got to create a HOLY sh*t-like cheat ability of my choosing, create a harem, make loads of money, sleep with a random babe, and do anything I liked; it’s that kind of story.
