Changing the world is simple. It is enough to choose an object and perform a number of easy operations on it. When an object (which is part of the world) changes in accordance with our wishes, a dispersing wave of distortions arises around it, and the world adapts to the new conditions under which the object can exist.
The easiest way is to operate yourself. To influence others or the environment in such a way as to the desired result, and not just to forge a sludge, can only true masters. Only an idiot can change himself.
