Before they knew it half of level-5 wizards had fallen down to the ground.
Mark's expression turned ugly when he saw the situation. He then made a decision to fully blast open it.
Boom~
The 5 level-6 wizards acted by releasing rule-based attacks. The unknown metal door wasn't able to block the attack.
Then it fell backwards down on the ground.
Swoosh~
Smoke rose from the ground and started to sweep away the hidden tunnel.
Then 5 of them quickly retreated backward to check everyone's condition. The unknown gas didn't cause any damage apart from the nauseating feeling.
But it's different for level-5 wizards. The level-5 wizards' mana core and mind are not well protected.
A few minutes later,
The unknown gas receded. But the expressions of the group leaders are ugly.
"Everyone's mana core and mind has been polluted," Daisy said in a solemn tone.
