"Boom!" A loud explosion sounded, dirt flying, smoke lingering.
Luo Zheng quickly picked up another grenade, calmly opened the safety pin, and threw it inside the Dark Fortress. To achieve the element of surprise, Luo Zheng dared not get too close before throwing the grenade. The first grenade exploded at the fortress entrance, scaring the people inside into retreating, intimidating them greatly, but with no actual effect.
"Boom!" Another dull explosion sounded; the grenade exploded inside the Dark Fortress. This kind of fortress couldn't be built very large; the people inside had nowhere to hide. Luo Zheng watched the collapsing fortress and quickly ran back the way he came, taking a moment to glance at Wu Yuan, who had also succeeded and was retreating.
