Deep Diver ambushes, as Lu Zixun expected, were bound to happen.
But Lu Zixun hadn't expected Sea Energy could also be used like this.
By using Sea Energy to create whirlpools, Deep Divers hid within them, infiltrated the Merfolk army, and began a massacre aided by the whirlpools.
The strategic plan to establish fortifications every kilometer in Hai Xin was utterly useless.
Because the Deep Divers didn't provide any opportunity to retreat while engaging in battle.
After the whirlpool dissipated due to Sea Energy, the Deep Divers had already perfectly withdrawn from the battle zone, leaving only a few corpses behind.
And the vanguard of the Merfolk army suffered heavy casualties.
Having just left Jerusalem and getting ambushed successfully by Deep Divers dramatically decreased the morale of the Merfolk army.
Facing this, Hai Xin sighed deeply.
