Greedy System: Charge To Level Up

Do you want to become stronger? Please charge!
Wang Jiu, who originally had nothing, suddenly received a system to get stronger.
There was almost nothing that could not be done as long as the money was paid. 
Too slow for cultivation speed? Charge, please!
Unable to learn the secret scripture of the Divine Arts? Charge, please!
As long as he recharged the money, he could become even stronger! Thus, Wang Jiu embarked on the path of charging!
