Ash encountered the Trial he least wanted to encounter—a maze.
The twelfth level of Silent Helix was, shockingly, a gigantic maze. Its walls connected heaven and earth, leaving no gap that could be flown over, and the walls, the ground, and the ceiling were joined into a single whole. Even if you attacked only one point on a wall, the damage would be distributed across the entire level of the helix.
However, Qikala, who was best at destruction, had stayed on the tenth level. Ash was good at cutting, Igula's hypothetical enemies were all intelligent beings rather than walls, and Gwen was not only merely a Two-Winged Sorcerer, but had also lost quite a few Spell Spirits due to the collapse of the "Multistar Concept" some days ago. His combat power could basically be ignored.
If they really wanted to brute-force their way through the twelfth level's maze, it would probably require over an hour of high-intensity output. But by then, their Spell Power would basically be completely exhausted. If they ran into the Mercury Trojan Horse on the next level after that, it would be practically delivering themselves to its doorstep, the heartwarming kind of situation where they took the initiative to let the Mercury Trojan Horse dig out their hearts.
So they had no choice but to honestly walk the maze. Still, the maze was not without clues. At every fork, a question would appear, such as "what is the most beautiful music in life," followed by three branching paths. Each path had a different sound: the white noise of rain passing through a forest, pure music with instruments flowing along, and a silent passage with no sound at all. If they took the wrong path, after going round and round, they would encounter the same fork again.
