「Boom——!」
The blast gun emitted a dull low-frequency shockwave, instantly tearing a savage gap in the protective mesh of the ventilation duct forged from reshaped alloy. Scorching smoke and debris exploded within the narrow secret room, only to be sucked deep into the pipes by the powerful negative-pressure wind.
Almost at the same second, the blast door was forced open by an external spiritual-energy projectile.
「Don’t move! Special Operations Bureau executing a search—」
Several icy spiritual-pressure infrared dots instantly pierced the smoke and dust, precisely sweeping across the interior of the secret room.
Yet all that greeted them was an empty obsidian room, and on the floor a pair of scattered gold-rimmed half-frame glasses reflecting a cold residual glow.
「Damn it! There’s an emergency escape passage behind!」The Special Operations Bureau captain’s expression changed as he looked at the gap leading into the unknown depths, barking orders: 「Pursue! Set the spiritual-pressure detector to maximum power! Once the Cold Marrow Toxin in his body activates, he absolutely cannot have gone far!」
However, the light spots on the detector screen remained eerily calm—only traces of violent heat left by pure yang energy remained; not a single trace of Shen Huai’an’s cold-poison spiritual pressure could be detected.
—Because at this moment, Shen Huai’an was being pinned down by Lu Xiao in an extremely domineering posture inside the vertical exhaust duct that could barely accommodate one person.
