Nice scene — I'll polish grammar, spelling and flow while keeping every sentence and idea intact and avoiding the em dash. Here's the cleaned-up version:
Ethan was looking around the city and spread out his mental domain.
It covered the entire place. It was the size of the solar system.
"Space manipulation? Who created this place? Any ancient Earth civilization or any alien civilization?"
Ethan had scanned the entire area, but there wasn't a single living being present.
He did, however, see some interesting things in the laboratories.
He entered a laboratory. It was a biological lab. There were many glass capsules, and inside those capsules he could see some abominations.
"Appraisal."
[Name: Vampwolf Abomination
Tier: 10
Talent: None]
"So this place was creating some abominations by crossing the DNAs of vampires and werewolves?" Ethan muttered.
"Interesting. They created a Tier 5 level being, but who created them? Humans or aliens?"
"System."
