Among the options displayed on the payment window, other than using federation coins to pay, there was actually another option.
Chu Nan looked at this option in confusion, "What are contribution points?"
After thinking for a moment, Chu Nan closed the payment window and opened the Help Menu to search for contribution points.
After reading the relevant explanation, Chu Nan understood.
It turned out that this so-called contribution point was the reward value given according to the contribution of every account on the forum. It could be used to do many things on the forum, including directly buying martial techniques.
This thing was probably equivalent to the virtual currency on the forum, but it could only be used on this forum.
