Underwater Glass Tunnel Action Sequence Seedance 2.0 Prompt

Hyper-realistic cinematic action sequence, 15 seconds, 16:9.
Deep beneath the ocean at night. A futuristic transparent glass transit tunnel runs along the ocean floor, surrounded by a massive black abyss. Outside the curved reinforced glass: dark water, glowing marine life, distant gigantic shadows moving through the depths. Inside: flashing blue emergency lights, wet reflective floor, warning alarms.
The scene begins already in chaos.
Two covert agents, a man and a woman in sleek black tactical clothing, faces visible, no helmets, no masks, are sprinting at maximum speed through the tunnel. They are not jogging. They are running for their lives. Their breathing is heavy, arms pumping violently, footsteps exploding through ankle-deep water. The camera flies backward inches in front of them, shaking with their movement.
Behind them, security forces sprint after them.
The tunnel suddenly violently shakes.
A deep crack rips across the glass wall.
The agents do not stop. They accelerate.
Glass fractures race across the tunnel like lightning. Water blasts through in powerful jets, throwing spray across their faces. They duck under falling metal beams while maintaining full speed. The floor becomes flooded, forcing them to slide and fight for balance without slowing.
The camera switches to a side tracking shot as the tunnel begins collapsing behind them. A massive section of glass ruptures. A violent ocean surge tears through the corridor, swallowing the security team and racing toward the agents like a tsunami inside the tunnel.
Ahead, the blast door is still open.
They are almost there.
Emergency sensors detect the incoming flood.
The blast door begins closing.
The agents are only meters away.
They sprint harder than ever. Their feet slip on the flooded floor. One falls forward, the other grabs their arm and yanks them upright while both continue running. No hesitation.
The water wave is seconds behind them.
The door opening becomes smaller.
They dive through the gap at full speed.
The blast door slams shut immediately behind them as the ocean crashes into it with explosive force, shaking the entire chamber. The agents slide across the floor, soaked and exhausted, while water pounds against the sealed door.
