Or?

It took Dyon 16 years to reach the peak of the comet level. During the monotonous 13 years he spent killing hundreds of thousands of beasts in his third trial, his mind was constantly reflecting upon the [Dao of Array Alchemy]. Still, he was simply too far from the planet level.

His first task should have been to find the location symbols of the array, but the moment he tried to, he realized that planet level arrays were organized very differently than what he was used to.

Every symbol was actually built upon each other like a complex, interconnected puzzle piece. To alter a single portion, one had to have enough knowledge to bypass the other layers without disrupting them.

The worst part was that this array was inextricably linked to 20-30 others, maybe more. This made it even more difficult to change the location symbols than Dyon had previously thought. For context, it was already wildly impressive that Dyon realized even this much.
