'I can't advance any further.'
Klein looked into the sky and instantly made a decision.
Klein still remembered the system's notification.
Not only was this crypt creature's blood magic extremely destructive, it even had a lasting effect.
Although Klein had advanced to tier 8 and his physical strength had increased a lot, he still didn't dare to be careless.
This was because the magic skills of these crypt creatures were likely terrifying innate spells.
Innate spells were the strangest.
Klein had felt their power time and time again.
For example, the Stone of Destruction stood on the earth with infinite magic power.
The Armored Scorpion could quickly burrow into the ground and come out.
As well as the Rouge Archer's invisibility and so on, all of them had brought great trouble to Klein.
If he couldn't find a solution, Klein would be exhausted to death!
