After leaving the lab room Aqua, Eclipse, and Snow led the shadow undeads to fight against the monsters who were present in the laboratory.
While they were fighting, Nekros and Astronox rushed forward, going straight towards the back of the laboratory where the elevator was located.
Some monsters tried to stop them but the power of Nekros and Astronax was very best among the A+ rank monsters so no one was able to stop them.
Nekros was using strength enhancement skill to increase his power by 100% so all the monsters who tried to stop them were torn apart by him.
Meanwhile, Astronox was stopping the attacks of the monsters who were attacking them from the distance.
Both of them worked in perfect harmony and soon they reached at the back of the laboratory.
