"Mental strength... after my breakthrough, there was a metamorphic change in my mental strength... Could it be that the previous enhancement of mental strength using the Cosmic Trading System wasn't a real enhancement? Or perhaps, something else wasn't enhanced?"
Suddenly, Lin Yun pondered on a matter that came into his mind.
If this was true, then he would have to be careful with the Cosmic Trading System's enhancement of various abilities.
"Brother Lin, have you just made a breakthrough to the Golden Core realm? But the impact... it seems too significant..."
Just then, Star Blue came over and looked at Lin Yun, speaking in slight astonishment.
He had also sensed the disturbance from Lin Yun's recent breakthrough, which appeared to be from breaking into the Golden Core realm, but found it somewhat hard to believe.
He himself was the practice of martial arts, and his civilization was mostly engaged in such practice too.
