Mark nodded at her fast reaction and was also shocked to some extent. If the zombie growls all the zombies in the staircase would instantly turn towards them and they would have to retreat up. Mona caught the head before it could fall down and slowly placed it down, not taking any risk.

Mark couldn't react as quickly as Mona, and he understood this as they killed the zombies. His physical condition wasn't at its peak and needed much more work to put into. All three of them continued their way down slowly and silently.

As they continued to go down the number of zombies increased in numbers. Mark and Mona continued to kill all the zombies either stealthily not to make it more problematic. Denton continued to stay behind them and lend a hand when he could.

At the 5th floor, Mark killed the last zombie off and looked around for any other zombie left. He also noticed the zombies on the stairs leading to the 4th floor were not disturbed. He slowly turned around and whispered to both of them, "Ok! Let's take a slight break here. I think the zombies would only be much more from now on."

Mona and Denton agreed as they slowly made their way up to the 6th floor and sat down. Mark felt exhausted as his body has still not adapted to the intense energy consumption he was going through. He slowly took out the water bottle in his bag and drank some water.

He handed the water bottle to Mona and sat there looking at the zombies they killed on the 5th floor. There were 7 bodies lying around at different places on the floor and stairs around them. It quite surprised Mark at the good teamwork he got with Mona.

Mona was able to cover him every time, and her agility and fast reflexes helped at various places. Her swordsmanship was opposite to how Mark practiced his back in the day, it was more refined and neat.

After a couple more minutes of resting, Mark stood up and said, "Ok, let's get going. The military must be waiting for us to open the door for them outside."

Mona and Denton could only nod and get up. Gripping his machete once again, Mark led the group to the 5th floor and then peeked over to the stairs leading below. He noticed there were only 2 zombies there. Turning around, he motioned Mona about this and both of them slowly made their way down.

Slowly descending, both of them quickly finished off the zombies and Denton followed them. Turning around towards the 4th floor, Mark noticed there were 5 zombies in the stairs and the floor.

Mona and Mark slowly went to the first zombie on the stairs and after killing it off, they turned towards the next one. They noticed the next one was already looking at them and before Mark could kill it; it let out a slight growl.

This caught the attention of the other 3 zombies on the floor and made their way towards them. Mark sliced the zombie off and looked at Mona. Mona gave a nod and both of them rushed towards the 3 zombies.

Mona was up against only 1 zombie while Mark took on 2. He kicked the first zombie away before using the same strength to slice the other head. He looked at the zombie on the floor and rushed towards it. He quickly slashed its head before it could get up.

He noticed Mona was already done with her zombie and Mark motioned Denton to come down. They continued their way down again and after killing the zombies on the 2nd floor, Mak noticed the stairs leading to the first floor had 3 zombies. He killed off 2 of the zombies while Mona killed one without a hitch.

As they turned around to the last couple of steps to the 1st floor, they noticed 8 zombies there. Mark could only exhale at the number of zombies. There were only 3 zombies on the stairs while the rest were on the floor.

Mark and Mona quickly went to the 3 zombies and quickly finished them. As Mona was done with her zombie, the body fell backward towards the floor and before Mona could stop it, it already rolled down making noises. As the body reached the last step all the zombies left already turned their attention towards them.

The five zombies ran towards them, Mona and Mark could only hold their weapons tighter and wait for them. Mark and Mona could successfully intercept 2 zombies each while the last one jumped on Denton who was at the back.

Mark quickly dodged the first zombie by ducking down and went for the one behind it first. He quickly tried to slash the zombie's head off. As the machete went right through the neck, separating the head from the rest of the body, he turned around and noticed the 2nd zombie already jumping at him.

Mark ducked again as the zombie went over his head and fell down. He acted quickly and slashed off its head and turned around. He noticed Mona was already almost done, but as he saw Denton, he rushed up to him.

Denton was completely struggling on the floor with the zombie on top of him, almost biting his head, only getting pushed back by the rod in his hand. As his arms almost lost strength, Mark quickly sliced off the head and kicked the body away.
