997 Archimedes Trouble

Boom!

A round was fired out of the muzzle.

Lu Zhou felt the heat of the bullet on his arms. The shell peeled from the casing, leaving behind a trace of smoke.

However, he didn't have time to react; his attention was totally focused on pressing the trigger.

Bang!

Bang!

The gun fired ten times.

All within ten seconds.

Lu Zhou turned off the safety switch and placed the gun on the table. He took off his noise-canceling ear muffs as Yan Yan spoke to him.

"Hit half of them in the chest target… Not bad, it only took you three days to get to this level. It took me a week to get to your level. Is there anything mathematicians can't do? Do you calculate the trajectory of the bullet?"
