He wasn't that kind of person.
The reason Xia Nan left one alive after clearing out the entire goblin nest and "watched" it die.
Was mainly to test the [Gravity Compression] (simplified version) he accidentally acquired in a Wild Mage's journal.
No need to filter original magic power through the Magic Net, nor pre-construct a Magic Model.
In the simplest way, using spiritual power to induce magic particles in the air, affecting the intangible "gravity."
Just like the Beast Priests and Bloodline Mages of ancient wilderness, no need to learn complex and extensive magic knowledge.
Which is very suitable for someone like Xia Nan who picked this up midway as an outsider.
It's just that, maybe he really has no talent in this area.
Over two months have passed since he got the journal.
With very little progress.
According to the method left by the Wild Mage, he concentrated his attention, and could vaguely feel his consciousness extending outward like tentacles.
