Jumping out of the river's dominion, Cave Heaven Comparison Ruler, relativistic effects...
These are different civilizations' attempts at understanding the same phenomenon. When two objects are in different reference frames, a situation arises where they cannot influence each other.
Except for the one and only measure that can cross different reference frames, the constant and absolute speed of light, nothing else can transcend it.
This is an ironclad rule. The iron rule of spacetime, the iron rule of motion.
For immortals, jumping out of the river is a defensive method superior to any protective Gang Qi. Once you jump out of the river, you are protected by the laws of spacetime and motion itself, and ordinary events can't affect you. And when others can't know what your personal time is, the harm they can inflict on you is extremely limited.
And now, has this layer of relative defense been breached?
How did he accomplish it?
