CONSTANCY: It is one of the unique properties of Otherworld, which is also the theme of this work.Otherworld, as a projection of reality, not only contains natural scenery such as mountains and rivers and human creations such as towers and cars, but also contains the human spirit. The projection formed by human spiritual activity in otherworld is constancy. Just as there are hot and cold temperatures, there are also positive and negative constancy.The constancy that is ubiquitous in Otherworld radiates various areas and materials of Otherworld. Normally, this radiation is harmless - the radiation of positive and negative constancy will neutralize and cancel out to maintain a dynamic balance.Once the dynamic balance is disturbed, the areas and materials will be distorted due to the influence of too much unipolar constancy and mutated towards the unipolar constant, which will cause a disaster.

Positive Constancy: Human spiritual activity tends to the irrational side. On one hand, it respects the human heart, illusions and beliefs, and the beautiful expectations that are idealistic and detached from reality; on the other hand, it rejects logic, refuses to analyze and understand, and even refuses to acknowledge the facts of the moment. For people with extreme positive constancy, there is no need for logical reasons to hold on to a belief, and there is no need to argue at all. It is enough to simply believe and hold on.

Negative Constancy: Human mental activity is inclined to the rational side. On one hand, it respects logic. The "Observe-Analyze-Understand-Predict-Control" thinking process is its best expression, which can often bring the optimal solution to man. On the other hand, it is the embodiment of cold reductionism and parameters. It sees people as a collection of parts or a mass of problems to be solved, rather than as a complete living human being. It rejects the unquantifiable fuzzy sensibility and tries to parameterize everything.
