"Talk?" Lu Chen's lips curled up in an icy arc. There was no warmth in that smile, only a chilling murderous intent. "Okay. Let him come. Bring his sincerity... and his brain."

He turned, his mithril arm wielding the magic blade, which traced a cold trail through the air. "The fortress can no longer passively accept attacks. We need supplies, information, and even more so... the power to proactively attack." His gaze fell on Wen Shifei's bandaged hands. "Any progress on the upgrade of the 'Resonance Virus' and the cracking of the Qingyi chip?"

Wen Shifei looked down at her hands, smiled bitterly and shook her head: "The injuries on my hands have affected the accuracy of my operation, and my mental strength has not yet fully recovered. Cracking the chip... is even more difficult. It uses multiple biometric codes and quantum encryption. Forcible cracking may cause Qingyi..." She didn't say anything else.

Lu Qingyi's face turned even paler, and she subconsciously hugged her arms tightly.

"Then let's change the route." Lu Chen's voice was firm, his mithril arm pointing towards the fortress below. "Integrate all forces that can still fight. Qingyi," he looked at his sister with a sharp gaze, "I need you to carefully recall all the people you have come into contact with who may know the details of the chaebol's 'Zero' plan or have researched biological weapons, regardless of their current stance."

He looked at Wen Shifei again: "Use the resources you have at your disposal to analyze the source of the stimulants in the Black Snake Gang's injectors. There must be someone behind Marcus providing him with these 'things'. Find the source."

"Brother...what are you going to do?" Lu Qingyi's voice was filled with uneasiness.

Lu Chen's gaze drifted toward the fortress's perimeter. Beneath the leaden sky, countless greedy eyes seemed to be hidden. "The fortress is the last bastion, but it's not a prison." He gripped the magic blade tightly, the energy lines on his mithril arm illuminating faintly. "The Game of Thrones has begun. They want the fortress's resources, Qingyi's 'key,' and my life... Let them take it."

His voice echoed across the observation deck like a cold declaration:

"But if you want to take it away, you have to pay with your life!"

As if to confirm his words, the fortress's shrill air raid sirens suddenly and shrilly tore through the oppressive air without any warning!

Woo-woo-woo-woo!!!

The sharp buzzing sound instantly spread to every corner of the fortress!

"Warning! High-energy reaction detected! Approaching at high speed from multiple directions! It's the chaebol's 'Razor' stealth attack drone! Number... twenty! Target: The fortress's upper defense nodes and energy centers!" The cold and rapid alarm of the "beacon" was heard from the fortress's internal broadcasting system!

Lu Chen entropy raised his head abruptly, and the pupil of his only remaining right eye instantly contracted! The magic blade held by the mithril arm hummed and vibrated, and the mercury luster flowed rapidly on the blade!

Wen Shifei and Lu Qingyi's expressions suddenly changed!

"Everyone! Take cover! Anti-aircraft fire! Full force!" Lu Chen's roar resounded like thunder, instantly drowning out the shrill alarm! He stepped forward, his icy mithril arm raised high, pointing the magic blade at the leaden sky! The blade pointed directly at the drone swarm that suddenly swooped down from the clouds, like the razor of death!

On the chessboard of power game, the first drop of blood has already fallen!
