"Boom!"
The sound of wood exploding suddenly came from the front.
Casio had unknowingly turned his gaze to the front while holding an umbrella in his left hand and a giant heavy machine gun in his right.
The machine gun was a Silver Monsoon model, meaning its silver bullets shot out in a frenzy, incredibly fierce like a storm sweeping the battlefield. Its caliber was 11.43mm, the gun weighed 27.20 kg, and it theoretically had a firing rate of 600 rounds per minute, or 10 rounds per second.
Click.
"Ta-ta-ta-ta-ta-ta..."
Machine gun bullets were spraying out crazily, drilling long, narrow paths through the rain and creating a powerful strafing of silver bullets.
The recoil hit Casio's strong body. His expression remained unchanged, only the umbrella held above his head trembled slightly.
Scattered raindrops splashed on the surface of the black umbrella and onto Casio's shoes, pant legs, lapel, and cheeks.
Meanwhile, directly in front.
