The missing requirement

He couldn't use his SCRY mode without his eyes, and was too busy when he got one back. He had checked, though, and the option to use it was there.

He wanted to check on Annoue, but he needed to first use it for the other target he could — Dormon.

He focused on his mode to activate it and then picked his target.

His sight started moving up through the floors at great speed, but he couldn't get many details through the trip about those floors. 

His sight reached the cell that he had seen Dormon being each time he had used his SCRY on him. No signs of anyone else in the other cells this time.

Shingi focused on his current form made by the Spell-like ability given by the System and tried to reproduce what he did last time with Annoue. In addition, he focused on manipulating the surrounding Spirit Mana to change his current form and allow him to communicate with Dormon.
