After Li Yan saw the formation activate, in scarcely five breaths, the spiritual radiance on its surface completely vanished. Even the seawater seemed to have lost its opposing force.
This made Li Yan increasingly aware of how extraordinary the formation was. After sitting cross-legged, he sent his Divine Sense outward without any concealment.
The three people in the distance showed no reaction whatsoever to Li Yan's actions. His Divine Sense then flew directly out of the formation.
Li Yan was not at all surprised that his Divine Sense could extend so easily. Formations like this were usually protected by one-way restrictions.
Otherwise, if those within the great formation could not inspect the situation outside, they would not even know when enemies approached. That would be no different from setting up obstacles for themselves.
After extending his Divine Sense, Li Yan discovered that spiritual power was still continuously radiating from the formation's surface, especially at a distance of around two inches from the great formation.
Two forces were continuously colliding there. Yet after the formation was powered by top-grade spirit stones, the spiritual energy driving it had been transformed by the great formation and became markedly stronger.
While resisting the force outside that was pulling away spiritual power, it unexpectedly formed a wrapping state. Nearly ninety percent of the colliding force spread outward in the form of waves.
This caused the force that diffused into the pitch-black seabed, amid the surging undercurrents around them, to flow away like seawater itself. The entire formation actually blended remarkably well into the environment...
As Li Yan's Divine Sense sensed the collision between the great formation and the seawater outside, he naturally would not entrust all their safety to the formation. Since matters had reached this point, he would do everything he could to help
