The sudden upgrade was a bit strange. Zhao Yu didn't plan to open any new hexagrams over the holiday, as he wanted to have a peaceful New Year. So, without new hexagrams, his adventure points shouldn't have grown.
This made him wonder… Why did the system upgrade automatically? Did the system give me extra points because of the New Year holiday?
He took a good look at the upgraded system interface. It had turned into a 3D interface and looked beautiful.
However, the system functions remained the same. It showed that he had only 400 points left at present, and the next upgrade required 10,000 points.
Zhao Yu clicked the device bar and found several new functions. One function enabled him to replace the devices that he didn't need with what he might find useful. However, each time that this device replacement was used, it would require a certain amount of points, which was not a good deal in Zhao Yu's opinion.
