Tampering something made by a strong being like Placake was always risky. That's why Rean took great care with the removal. "Sister Orb, can you see anyone coming to the room where the claws are located?"
[You can see the outside, too, no? Anyways, I can't see anyone.]
Rean and Roan nodded after hearing that. "Better to be safe than sorry. Let's go."
Rean and Roan's appearance then immediately changed, making them look like some random member of the System Sect. They didn't use the Circuitry Teleport Formation in the Dimensional Realm, though. That thing would teleport them randomly in a specific direction. The experts watching the System Sect know where the exits of its teleport formations were located. So it would be too suspicious if the twins suddenly appeared somewhere different.
