If it weren't for the system's prompt, Lin Shiming would hardly believe this was a Transmission Formation, let alone one belonging to the Sea Demon King Court.
This simplicity is a bit too much!
On the altar, there's still a layer of light-colored Spirit Shield, which evidently is the Spirit Formation for blocking detection and also protects the Transmission Formation.
However, Lin Shiming doesn't care much about this. Such detection-blocking Formations that are activated all year round actually don't offer much defense. Even a Third-Rank Supreme Grade blacktip shark can break the Spirit Shield.
Thus, Lin Shiming knows that there must be something hidden. As he probes further, he spots two Fourth-Rank Black-Scaled Pythons only showing their tendrils, undulating like seaweed in the water – if one does not look carefully, they are indiscernible.
Lin Shiming scans the surroundings once more, making sure nothing is missed, and then takes out a Jade Talisman.
