At the same time as the Bone Prison shattered, the shrimp leader snuck up and attacked Dean McKenzie with its remaining pincer, smashing against his Bone Armor.
This strike gave Dean a fright.
With one blow, the Bone Armor protecting Dean was shattered.
Even the Earth Guardian passive from his Meditation skill housed within the Bone Armor had been broken. If not for Dean's Invisible Shield, he would have perished on the spot.
A quick estimate put the Shrimp Commander's strike at over 70,000 in power.
This level of attack power was simply cheat-level.
Luckily, Dean was a cheat too, so he eventually triumphed.
After withstanding the attack, Dean retaliated by sticking his Bone Fang smack on its forehead, killing it on the spot.
With the death of the shrimp leader, the remaining shrimps posed no threat.
Dean tried to beat them into submission and confine them to the Land of Bone.
But it was impossible.
Old Six's dungeon couldn't contain such high-level beings.
