Whether it is necessary to change the requirement of shape multiplier upgrade from completely requiring thousands of study points to requiring the coexistence of a portion of study points and some difficult graphs or thousands of study points. The shape multiplier upgrade after Level 3 requires thousands of study points, which is too difficult to obtain, and the number of shapes required for the researcher upgrade has increased too much, while the number of study points produced by the task has not increased. The output of the study points for these two points is too different from the points required for the shape multiplier upgrade. This makes it possible to hang up for a long time to get enough research points. It was a bad experience.
