One's own will stood above all else.
For Tian Yuanli's Truth of One's Own Heart, this was reality. It was not merely a description, much less some boring fantasy.
Without needing to pay any price, one could use one's own thoughts to revise the world's fundamental rules and forcibly mold the world into whatever shape one needed.
In short, this was an ability that allowed its wielder to customize the world.
In a sense, it was rather similar to Xi Shenlian's Environment Adjustment Sandbox, except it was far more advanced. It was a power that truly required no price whatsoever.
As a device specifically used to adjust the environment, the Environment Adjustment Sandbox essentially modified the world based on existing conditions whenever it operated.
For example, when faced with a mountain, it could dismantle and reshape it, successfully transforming it into a desert, an ocean, metal... But it could never directly create the corresponding things from nothing and use them to cover the mountain.
To a certain extent, everyone could regard it as something that was at least somewhat scientific. Its operation required vast amounts of energy and matter to modify the world. It was not a reality-overwriting power that ignored every fundamental law.
At most, it could only be considered a reapplication of various fundamental rules.
Tian Yuanli's Truth of One's Own Heart, however, was far more unreasonable and far more arbitrary than the Environment Adjustment Sandbox.
It completely disregarded the so-called laws of conservation of energy and conservation of matter. By casually modifying reality, it could twist the world into all sorts of forms its user needed, even when doing so was utterly unreasonable.
Take the example above. If Tian Yuanli wished, she could create matter from nothing and enlarge that mountain countless times over. Or she could
