On the ninth floor of the Gray Tower, Levi looked at the proficiency panel and pondered.
Previously, when he fused the breathing technique, he had used low-level to fuse it with high-level ones. He had never fused it with anyone of the same level.
The Man-Faced Spider Breathing Technique and the Night Owl Breathing Technique were both at the Maximum level 6. Their levels should be about the same.
When Levi fused the Night Owl Seed with the Human-Faced Spider Seed, he felt the Night Owl's struggle. It seemed that it was more challenging to fuse at the same level as the high-level fusion.
The two evenly matched breathing technique seeds were unconvinced and fused with each other.
In the end, a strange seed appeared in Levi's heart.
"Seed of the Human-Faced Owl."
In the legends, there was no such thing as a human-faced owl, so this should be considered a mutation...
