Atlas followed the winding tunnels that the qi channels flowed through. If he were to follow the same path without deviating at all, he would have circled all the way back to the place where he started.
In reality, the web of tunnels that connected all of the tomb's mechanisms and traps was more like a labyrinth. To those who knew its structure, navigating it was simple and efficient. To an outsider, however, it was like an infinite maze.
When he realized that finding his way to the final destination wasn't so simple, he immediately channeled his qi into his eyes, activating [Intrinsic Foresight].
He couldn't perfectly see through these walls, as they'd been reinforced with qi, but he could see a vague picture of what was beyond.
As long as he had it, he could at least choose which few paths seemed best and compare them instead of moving randomly.
