Chapter 5698“His mind has been corrupted by demonic energy and these chains!” David instantly realized.This fourth floor was nothing short of a trap, amplifying evil thoughts and luring people into demonic possession! Those so-called “treasure” illusions were just bait!Old Hei’s mind was relatively simple, making him easier to exploit!Facing the frantically charging Old Hei, David couldn’t deliver a fatal blow, only able to passively defend and parry.Boom! Boom! Boom!Old Hei’s fists crashed down like meteors, each strike containing the power to shatter mountains and split the earth.David, relying on his exquisite footwork and sword intent, maneuvered around them, the Dragon-Slaying Sword colliding with Old Hei’s fists, producing a deafening metallic clang. David‘s blood surged from the impact, his tiger’s mouth splitting open.Killing Lao Hei would be easy for David, but controlling him without harming him was a different story.David hesitated, constantly retreating.“Mr. Chen, this won’t do! We must awaken him!”Cen Biqing tried to soothe him with the Azure Dragon’s Voice, but the sound waves were easily deflected by the demonic energy surrounding Lao Hei.“I know!”David struggled to defend himself while observing.He discovered that the black flame chains were the key!They weren’t just attacking Lao Hei, but also continuously injecting demonic energy into his body!“I must sever these chains first!”David’s eyes sharpened, and he abruptly activated all the sword intent within him, transforming himself into a drawn sword!“Slash!”A highly condensed, thread-like sword aura, seemingly capable of splitting yin and yang, shot out, its target not Lao Hei, but the black chains connecting him!Chichichichi!The sword aura severed several chains in response! The broken chains emitted a sharp screech as they dissipated into black mist.The chains snapped, and Old Black’s body jolted violently. The crimson in his eyes faded slightly, and his movements froze for a moment.“Now!”David seized the opportunity, lunging forward and pressing his palm against Lao Hei’s forehead. The pure, regal golden dragon essence surged into Lao Hei’s consciousness without reservation! “Lao Hei! Wake up! You are a noble black dragon, how can you be controlled by demonic thoughts!”The golden dragon essence, like the sun melting snow, rapidly purified the demonic energy in Lao Hei’s consciousness. Lao Hei let out a painful roar, his body trembling violently, but the crimson in his eyes was rapidly receding.A moment later, Lao Hei’s massive body shuddered violently, vomiting a mouthful of foul-smelling black blood. The madness in his eyes finally vanished completely, and clarity returned.“Mr…Mr. Chen…I…” Lao Hei looked at David and his disheveled state, his face filled with fear and guilt.“It’s alright.”David withdrew his hand, his face somewhat pale. The continuous high-intensity battle and exhaustion had taken their toll.Having rescued Lao Hei, David didn’t dare delay and immediately went to the stairs leading to the fifth floor.The protective barrier here was incredibly thick, with runes flowing across it like living tadpoles, emitting a chilling spatial repulsion force.“That pseudo-dragon guy on the fifth floor is incredibly cunning; he ambushed us last time,”David said in a deep voice.“Let’s attack together!”noveldramaLao Hei, now recovered, was full of fighting spirit.David, Cen Biqing, and Lao Hei stood in a triangular formation.David circulated his Five Elements Origin and sword intent, Cen Biqing activated the Azure Dragon Power, and Lao Hei unleashed the Black Dragon’s brute force.“Attack!”The three attacked simultaneously! A five-colored sword aura, a blue dragon breath, and a black shockwave slammed into the protective barrier on the fifth floor!Rumble—!The entire Demon Suppression Tower shook violently! The protective barrier flickered wildly, the runes on it flashing and cracking, but it stubbornly remained unbroken!“Not enough!”David gritted his teeth.He could sense that the restriction was connected to the core of the entire tower, and its power was continuous.
