Slowly Eliminating the Enemies
The group of one of the heads, oblivious to what had happened above, entered the building before entering the two elevators that led to the highest floor. The group had 20 members, but only 7 of them were Tier IV combatants. The elevators were large, but they couldn't fit 10 people each, so in the end, the 7 Tier IV combatants, alongside 4 more members entered the two elevators.
The man that called for them, whose name was Jack, entered one of the elevators with them. The strongest amongst the 11 was a mid-grade Tier IV combatant while everybody else was a low-grade Tier IV.
Previously, upon the destruction of the last floor, the groups panicked as debris started falling down, even injuring some of them. They realized that the situation above was far more dangerous than they thought, but upon seeing Jack, they all relaxed as they were certain that they had won.
