"There are about three hundred Alabaster Bullmen; he killed all of them." said one young man in a shaking voice. 

"How much time it had been since he left us, not even three minutes, but he killed more than six hundred Grimm Monsters in that time," he added.

He is no weakling who can not handle death; he had participated in the battles where hundreds of thousands of Grimm Monsters died within an hour and saw the tens of Platinum Elites fighting against each other, even surviving the attack of Platinum at once.

But seeing this range of killing at such swift speed, even he was shaken seeing this, as he is aware that the Alabaster Bullmen that came to attacked the Camp was not the normal Grimm Monster, even he will need at the least one minute minutes to finish off, but the other party did not take even a second.

"Excelsior.' 

Muttered a girl beside him, when he heard that he couldn't help but shake a little, it had been quite a while since he listened to this word, but when he thinks about it, he indeed has the power to be called 'Excelsior.'

"Find that bastard and kill hi" Was saying one Alabaster Bullman, but before it could off the sentence my knives pierced through it and those beside it. 

I am currently on Wing 29 and facing about five hundred Grimm Monsters, or 300 as I had killed two hundred in the past three minutes.

Such numbers of monsters could not be killed through the confrontation in the packed spaced like a camp; they could easily drown me in their attacks, which is why I am playing hide and seek with them.

It was a good thing. Grace not only gave me maps but also the authorization, which helped many open doors and launch sneak attacks in them. In each attempt, I would kill fifty to hundred Grimm Monsters before running away.

These bastards have broken several doors to chase after me, but by that time, I would be already launching the attack.

It is all being possible due to the Featherlight Method, the speed it had given me is beyond amazing, it had made me invincible in my level, if not for we are fighting in the close space, I wouldn't have felt any fear to confront them directly.

But since it is closed spaces, I have to be careful and attack them sneakily before running away, as getting hit by their attack means dying.

I continued launching the sneak attack on them, and finally, three minutes later, I killed all of them. Just as I did above to move away, I saw the people I've left behind in Wing 8.

"There are some Alabaster Bullmen hiding, help me clean them before you come down," I said. I had deliberately left some Alabaster Bullmen when I saw them coming.

The Grimm Monsters numbers are going to increase lower ones go, and these twenty-some people are no match for such numbers, especially in limited spaces where hundreds of monsters could easily drown you in their attacks.

Their self-confidence would have taken the hit if I had directly said that which is why I had decided to leave some Alabaster Bullmen for them to deal with, by the time they finished dealing with it, I would be able to clear the floor below.

Soon I reached Wing 30, and there I sensed more than 600 Alabaster Bullmen lying in wait for any humans that would come from above. I could see bodies of humans lying around and some Alabaster Bullmen even eating them in passing as they wait.

After killing the sentries, they have places to alert them of any human activity; I take a look at the map and plan my attacking strategy in a few seconds before I use authorization to open the door.

Sup Sup Sup…

I opened several doors, till I opened the door that leads me toward the center where Alabaster Bullmen gathers. 

I opened that door and released knives at my greatest speed, and four seconds later, when Alabaster Bullmen finally reacted, I closed the door and moved toward another to use the same strategy. 

The small spaces have many disadvantages, but they also have many advantages, especially when a single person kills a shit load of people. I continue to sneak attack and finally am able to kill off all the Alabaster Bullmen on Wing 30.

After making sure no Alabaster Bullmen remained on the Wing 30, I sped toward the Wing 31, I saw completely different scenes that I saw in the other wings. In Wing 31, there are more than a thousand Alabaster Bullmen, but few hundreds of humans are also fighting against them.

Though humans are suppressed heavily as there are barely two hundred of them, they are still fighting bravely without any sign of Cower, seeing that smile couldn't help but appear on my face.

This time, I did not use my knives; instead, I took out the red sword I hadn't taken out in quite a while and sped into battle. I want to get the feeling of killing with my own hands.

Puchi Slice Puchi Slice Puch…

Faint purple lines covered my body as I moved in the battlefield, I and my sword have completely become phantom in the battlefield, taking cutting lifelines of several Grimm Monsters every second.

I was quite surprised to find that the killing speed of my sword is not much lower than that of my knives, but the contentment I am feeling through killing them with my sword is far too greater.

With the sword, I could watch life leaving the eyes of Grimm Monster from up close. I did not enjoy watching life leaving the Grimm Monster but I still feel content killing them.

With each kill, I am saving some humans as these monsters if they survive going to kill hundreds of humans, so it is important to kill them before they kill us, and this is not the thoughts of the killer but the doctrine that passed in Grimm Battlefield.

The more Grimm Monsters you kill, the more humans you will save. This doctrine likely was created to maintain the psychological balance of the people who fight in Grimm Battlefield to create purpose in their heart, which is purer than the War.

A minute after I joined the battle, everybody had noticed me as my rate of killing is too high and Grimm Monsters came at me with tooth and nail but funny things, more than half of the Grimm Monsters thwarted by humans and while those who came at me were killed by me easily.

This is closed space, and given the six-meter sizes of the Grimm Monsters, not many of them came at me at some time which helped really killing them and another thing, the closes space also helped me quite bit surviving against the attacks of Alabaster Bullmen as I would use the bodies dead and alive Alabaster Bullmen as a meat shield.

As such, twenty fifteen minutes had passed, and in these fifteen minutes, all the Grimm Monsters on the Wing 31 had been slaughtered by me.
