Andre always held a butterfly knife in his hand, and as his face suddenly changed, he immediately stabbed the knife into that unlucky bastard's arm.
Andre's two bodyguards held the captive firmly on the ground, while Andre's knife was slowly slicing down the unlucky bastard's arm. He wasn't lying; he truly intended to skin the captive alive.
The captive screamed like a pig being slaughtered, and he howled desperately, "Stop! Stop! I'll talk! The exit is in that building, but part of the secret passage uses the existing sewer, and they might have missed another entrance and went the wrong way! Stop it!"
Gao Yang shouted fiercely, "Where does the sewer lead to!"
The captive screamed, "The Dnieper River! All the sewers here lead to the Dnieper River!"
Djo Malthael must have encountered some accident, otherwise, he should have left through the exit long ago. Since he hasn't left, then he must have taken the wrong path rather than being trapped in the tunnel.
