Unlike the technological structure before,
the corridor where Han Dong currently stands is composed of ancient stone blocks etched with patterned rules,
with metallic particles embedded at the junctions and corners of the stone surface patterns, forming a highly restrictive closed structure.
Even Han Dong, who was originally unaffected in the Deep Layer, can perceive a sense of restraint.
Since the restriction here has further strengthened, it essentially indicates that the area Han Dong is about to reach is the true face of the Deep Layer, the core containment zone of the B.B.C.
Similarly, the metal bracelet is also being blocked,
however, the red light that flashed before being blocked was exceptionally bright, indicating that the area Han Dong is in is considered an "absolute forbidden zone" by Director Charles.
"It seems the area I'm about to reach is no longer the previous 'office area', but a true containment zone.
