Actually, it's not very significant, at most it's just icing on the cake—having ample Passive Points allows for such indulgence.
So, what qualifies as offering someone charcoal in the winter?
Xu Xiaoshou looked at the two "Sovereign (stage) Lv.1" passive skills that were out of place among his "Holy Emperor Level 0" skills:
"Cooking Expert (Sovereign stage Lv.1)."
"Drawing Expertise (Sovereign stage Lv.1)."
When Expertise Passive Skills reach the Sovereign Lv.0 stage, combining with his current abilities and evolved mindset, he could definitely achieve remarkable results.
A Level Four Skill Point isn't expensive, just fifty thousand Passive Points each.
With a million, he could resolve these two major passive skills, gaining a fresh way to enjoy the Demi-Saint level "Cooking" and "Art"...
This is very good!
It will definitely change his current battle tactics!
Of course, there's another path.
