This was the latest model of general-purpose hand grenade produced by the Great Tang Group, smaller than the previously used stick grenades to facilitate soldiers carrying them and reduce the logistical support pressure.

Although stick grenades could be thrown farther and could prevent rolling upon landing, they were far too large compared to the egg-shaped grenades, taking up a significant amount of transport volume and increasing usage costs.

Moreover, for individual soldiers, carrying egg-shaped grenades was obviously easier than carrying stick grenades, and they could carry more of them in relative terms.

The troops of Zheng Country had clearly never seen such a round explosive, so when one soldier saw something fall at his feet, his first reaction was to look at the object engraved with horizontal and vertical lines.

The next second, as the fuse ran out of time, the grenade exploded inside the trench, creating a storm of metal.
