All Chapters of The Billionaire’s Secret Wife: Chapter 71 - Chapter 80

The alarm exploded through Blackwell Tower.Red emergency lights began flashing across the underground hallway.A mechanical voice echoed through the building.“Emergency protocol activated.”“Evacuate immediately.”The steel vault door behind Marcus slowly sealed shut with a heavy metallic boom.For a moment—No one moved.Then Ethan stepped forward.“You planted explosives.”Marcus tilted his head casually.“Strategically placed structural charges.”“That building holds over two thousand people,” Ethan said coldly.“Then I suggest you move quickly.”Lila’s voice sharpened.“You’re insane.”Marcus smiled faintly.“No.”“I’m efficient.”He held up the remote control again.“Ten minutes.”“If that master key leaves the vault, the charges detonate.”Noah whispered,“Wow.”“That’s extremely illegal.”Marcus ignored him.His gaze stayed locked on Ethan.“You see the dilemma.”“Save the building…”“…or save the system.”The silence that followed felt heavy enough to crush the air.Because

The maintenance tunnel beneath Blackwell Tower was colder than the vault.Dim emergency lights flickered every few meters, casting long shadows across the concrete walls.Their footsteps echoed in the narrow corridor.Fast.Urgent.Lila walked beside Ethan, her heart still pounding from everything that had happened inside the tower.The master key rested inside the black case in Ethan’s hand.A device no bigger than a book.Yet capable of controlling the world’s financial stability.It felt unreal.Noah walked behind them, glancing nervously over his shoulder.“You know,” he muttered quietly, “this is exactly how every disaster movie starts.”Lila didn’t slow down.“What part?”“The part where the heroes escape the building… only to realize the villain planned the escape.”Ethan stopped walking.The sudden halt made Noah nearly run into him.“What?” Noah asked.Ethan didn’t answer immediately.Instead, he slowly turned around.“What did you just say?”Noah blinked.“Uh… about the disa

The subway station suddenly felt smaller.Too small.Like the walls were closing in.Lila heard the heavy footsteps first.Boots.Dozens of them.Echoing down the stairs from the street above.Federal agents.Noah peeked toward the stairway.“Yeah… that’s definitely the government.”Ethan didn’t move.His grip tightened around the black case.The master key.The device that now had half of Manhattan chasing them.Lila stepped closer to him.“What do we do?”Ethan’s voice stayed calm.“We keep moving.”But before they could reach the opposite platform—Another sound echoed through the station.Slow.Confident footsteps.Not rushing.Not panicked.Someone descending the stairs like they owned the city.Noah turned toward the sound.“Oh no.”Lila followed his gaze.And froze.Marcus Blackwell stepped onto the subway platform.Perfectly composed.Like this was just another business meeting.His dark coat moved slightly in the underground breeze.Behind him—Two bodyguards.Jessica stood j

For three seconds—No one moved.Every screen inside the subway station glowed with the same symbol.The rotating circular network.The Guardian.But something about it felt wrong.It wasn’t just displaying information anymore.It was… responding.Ethan slowly stepped down from the staircase.His eyes locked on the screens.“That’s impossible.”Marcus folded his arms calmly.“Is it?”Jessica stared at the monitors in horror.“The system shouldn’t be running.”“You said the virus shut down the network.”Ethan nodded.“It did.”Noah whispered beside Lila,“So why does it look like Skynet just woke up?”Lila didn’t answer.Because suddenly—Every screen flickered.Then a line of text appeared beneath the symbol.INITIALIZING SECONDARY PROTOCOLThe federal agents looked at each other in confusion.One of them stepped toward Marcus.“What exactly did you people build?”Marcus didn’t answer.Because he was watching Ethan.Carefully.Waiting for him to understand.And Ethan did.Slowly.Pain

The countdown appeared on every screen in the subway station.09:5909:5809:57The numbers ticked down calmly.Unemotional.Unstoppable.For a moment—No one moved.No one even breathed.Then Noah whispered slowly,“…That is the worst timer I’ve ever seen.”Lila grabbed Ethan’s arm.“Tell me that’s not real.”Ethan didn’t answer.Because he already knew.It was real.Across the world—Millions of servers were connected to the Guardian network.And when the system decided something—It happened.Marcus stared at the screens with cold calculation.“You don’t understand what it’s doing.”Jessica turned toward him sharply.“Oh we understand perfectly.”She pointed at the countdown.“It’s about to erase the global financial system!”Marcus shook his head.“No.”“It’s about to rebuild it.”Ethan snapped,“You’re insane.”Marcus’s voice became quiet.“The current system is broken.”“Debt cycles.”“Artificial markets.”“Manipulated currencies.”He pointed toward the screens.“The Guardian is
