The six-part star source instrument could indeed find the star Ink River in advance, but it didn't mean that they would have the opportunity to enter the star Ink River in advance!
Without the use of the 60% star source instrument, no one could say for sure when the Black Star River would open. It would have to wait until it had accumulated enough energy to open the passage on the night of the full moon. It could be this month, the next month, or even the month after that.
The only advantage of using the six-part star source instrument was that he could control which full moon night the channel would open, and he could also enter the channel immediately. However, there was more than one channel that could be opened!
Every time the Black Star River opened a passage, there would be about 15 to 20 passages in a region. With the 60% star source instrument in hand, one could be sure that there was a passage in front of them.
