Tommy cradled the barrel in his arms, took two steps back, then turned and sprinted before dropping to one knee. He placed the barrel onto the deck, gripped it with his left hand, and with his right hand swiftly slipped a mortar shell, already fitted with a fuse, into the muzzle.
With a blast, a target on the sea surface shattered in response.
Using just a barrel, Tommy demonstrated a rapid, single-person firing technique, relying solely on memory to hit a target without sight.
Surprise, Tommy's demonstration was a pleasant surprise for Gao Yang.
The thing about mortars is that they're not particularly technical; a few glances and one could use them. But it's one thing to launch a shell, quite another to hit the target accurately.
