Shinshiki had declared from the outset that this real Tsukuyomi World was an eleven-dimensional space, just like Takamagahara, so none of Yu's spatial techniques could let him escape.
But even in this desperate situation, Yu decided to try!
Again and again, he tried to open Yomotsu Hirasaka using familiar spatial coordinates, but those coordinates, which had never failed him before, no longer worked.
With different dimensions came different rules.
Yes, the real Takamagahara was the same.
No spatial technique could grant entry or exit. The Heaven-Piercing River, which crossed dimensions, was the only way in or out.
That was why the Ōtsutsuki operating outside could not flee back to Takamagahara, even when their lives were in danger.
When Yomotsu Hirasaka failed, Yu tried sucking himself into the Kamui Dimension... but that failed too.
After a long period of thought, Yu reached a conclusion. "Just like the Double-Moon Space, time flows differently here, so Kamui can't reach it directly."
In this Tsukuyomi World where Yu was trapped, Shinshiki had complete control over the flow of time. One second outside could be a year here.
Meanwhile, time still flowed normally in the Kamui Space-Time Dimension. The difference between these two spaces was hundreds of thousands of times greater than that between the Double-Moon Space and the outside world, if not more.
What did that mean? Even if Yu were ten times stronger than he was now, he might still be unable to cross that temporal barrier!
That meant... Kamui was completely useless in this Tsukuyomi World too!
Yu felt both helpless and relieved.
At least everyone in the Space-Time Dimension would not have to endure a century of torment like him!
With every means of escape exhausted, Yu stopped wasting chakra pointlessly.
He sat cross-legged on the desolate ground beneath the moon
