Just as he thought that, an armored vehicle with treads came out from behind a different building. It was about 20 meters away. It had a rotating gun turret with barrels lined up in parallel on both sides. It also had a plate-like antenna. It may have been more of an anti-aircraft gun than a tank.

They put aside the guns and fired a surface-to-air missile instead.

With a trail of white smoke, the explosive flew toward the half-destroyed gun emplacement.

“God dammit!!”

Hamazura frantically jumped to the side away from the gun emplacement he had been using as a shield.

An explosion occurred immediately afterwards.

His sense of hearing was blown away.

His body floated in the air from the intense blast. After landing on the snow, he looked around the area. He just so happened to be behind a building. He was pretty sure he was 10 meters away from the gun emplacement. That was not due to his own ability. That was just how great the blast had been.
