Damned if you do, damned if you don't

System: Congratulations! You have level up. You gained 3 base points and 1 skill point.

As soon as the Sorting Hat Spider fell, Ye Yan heard the system notification telling him that he had leveled up. 

Ye Yan was really surprised by it because he had reached level 8 just yesterday and thought it would take at least until tomorrow for him to get one level. 

The experience he got from the mausoleum was huge. Ye Yan was killing monster two levels higher than him alone and many were elite at the very minimum. And he even killed a Lord-level monster in the end. 

Even if killing monster two levels higher than him didn't give a bonus in experience, the amount it gives is higher than level 8 monsters. And the amount of experience he got from the elite monster and bosses was too huge. The last boss alone gave 1,200 experience points.
