So you can refine all those Ninjas once a day to ac*ulate points. When you've ac*ulated enough points, the following are the exchange "programmes".

Basic Refining (200 Points) : 20,000 Coins OR 500 Cultivation Runes
Medium Refining (3000 Points) : 10 Iruka Fragments + 2 Seal Scrolls OR 4 Summoning Scrolls
Advanced Refining (15,000 Points) : 1 Naruto Fragment + 8 Seal Scrolls OR 16 Summoning Scrolls

*Note: When there's an option between the OR, you don't get to choose which of those you want. Meaning you don't get to choose coins or ruins, neither will you get to choose seal or summoning scrolls. Those items are given randomly. The 10 Iruka fragment or 1 Naruto fragment is guaranteed though.

Omg... This really got to me. I can't stop laughing. :lol
