As Lin Caisang just started speaking, she heard the voice of her elder brother.
Lin Changhong held his chin in one hand, gazing at the vortex door with a thoughtful look.
"Mechanism?"
Several people reacted to his words and spoke up simultaneously.
They had never heard of anyone setting up a mechanism at the vortex, only knowing about formations.
"Could it be a formation then?"
"It's not a formation, it's a mechanism."
Sui Zimo also examined the vortex seriously before confirming that it was indeed a mechanism; the entire vortex was made up of a mechanism.
If they wanted to enter the eighteen layers, they had to unlock this mechanism.
"What to do? We've never heard of such a mechanism," a female team member asked everyone.
They couldn't even get close to the vortex, let alone figure out how to unlock the mechanism. Even Young Master Sui, with the deepest spiritual power, was repelled.
"How do we unlock this mechanism? It's too difficult, isn't it?" Captain Liu also asked.
