Noah didn't have the power to pull the entire Pterodactyl outside of the cage, and he found it hard to do even with the creature's new form.
The metal bars hurt the Pterodactyl's mind inside the dark matter, but the fact that a trail of higher energy connected it to the outside created a minute path where it could pass.
Noah's pulling force didn't rely on bare strength. His mind didn't have such capabilities. The higher energy's unique properties confused the cage's restricting ability, allowing him to retrieve the invaded part of dark matter if he went all-out.
The procedure for him was relatively easy compared to what the Pterodactyl was going through. The mysterious inscription method used on the bars ripped its mind apart whenever part of it escaped the imprisonment.
Noah felt delighted at that sight. His worries eased when he saw how badly the cage hurt it.
