Fantasy: I Have Billions of Spiritual Stones

What? Traveling through a fantasy world? Becoming a useless disciple? This is not the point. The point is that I have bound myself to a super powerful system? "Ding dong! After receiving the main mission, 100 million spiritual stones will be spent within one year!" Regarding such a low request, Xiang Nan said righteously: "Give me another 100 million!" "Ding dong, the main mission has been updated, and 200 million spiritual stones will be spent within one year!" Faced with the 200 million spiritual stones at the beginning, Xiang Nan started an extravagant consumption. A few years later, the powerful people in the fantasy world discovered. The Danyun grade elixir that they regarded as a treasure was eaten by Xiang Nan like candy! He used an artifact that he had never seen in his life as a fire stick. Even the ancient secret technique is used as a piece of paper to wipe one's butt. It's so arrogant!
