After a moment, Fang Heng withdrew his mental strength.
The barrier before them should have been an accidental byproduct.
Originally, the sealed barrier had been a standard one-way passage structure.
Its purpose was aimed at life forms attempting to escape from inside the barrier.
This design logic was easy enough to understand.
The original intention of the Sea Abyss seal had been to seal ancient sea monsters. If the seal were ever broken, the outer seal could continue holding for a while longer while simultaneously detonating the outer spatial turbulence, using the power of the spatial turbulence to destroy most of the Sea Abyss giant monsters.
Therefore, the barrier's defenses were mainly directed toward the inside.
Due to a series of coincidences, Charlene and the others had accidentally triggered spatial fluctuations, causing the Sea Abyss spatial undercurrents to surge and unexpectedly fuse with the defensive barrier, leading to a further mutation of the barrier.
