But it existed in other indescribable and incomprehensible ways.
For example...
Right in front of him, what had just given him a fright...
The Mirror at 00:42.
"Space-Time Rift."
Lin Xian muttered the concept:
"Perhaps the existence and appearance of the Space-Time Rift are related to 00:42, this particular time. After all, the ultimate answer to the universe is 42; the time I travel through dreams and leave them is also 00:42; and so is the time related to Millennium Stakes."
"Thinking about it this way, the occurrence in the Mirror at 00:42, if thought of in connection with the Space-Time Rift, becomes not difficult to explain."
With that thought...
Lin Xian couldn't help but sigh with relief...
Thankfully.
Thankfully, theoretical science can explain it.
Never mind whether this theory is temporarily correct or not, at least it can prove that the situation just now wasn't some kind of scary ghost story or supernatural event.
Human cognition is strange on this point.
