Additionally, another method was to know the spiritual frequency of this Heart Domain and actively seek it out in the Fourth Dimension. By verifying access, one could enter.
Brian had used this method the second time he entered the collective Heart Domain of the Big Octopuses.
Two methods.
The former was applicable to both the strong and the weak.
The latter only suited the strong.
Ordinary people, even general Third Rank Lifes, lacked the ability to perceive the Fourth Dimension, let alone actively approach it in that dimension.
Thus, for Brian, the only option was the first method.
This method had two issues to resolve.
The first issue was how to align someone else's spiritual frequency.
The second issue was how Brian could ensure his "door" had a broad enough reception range.
For the second issue, Brian already had a solution.
However, it was the first problem that he didn't quite know how to handle.
Blu hadn't provided him with an effective solution either.
