He is a brave firefighter.

This festival is held every year.

The firefighters quickly carried out the fire extinguishing operation.

The fire was extinguished immediately.

He solved the problem rapidly.

I'm always amazed at the speed of his work.

The fire department works around the clock to prevent fires.

He was immersed in his work all day.

He was working all day.

He always had the spirit of a samurai in his heart.
