Another morning has come, and now we have a very clear edge over the Grimm Monsters and cutting them like grass, but Grimm Monsters are also fighting with their all, making us lose many people too. 

I wish the battle would end soon and wishing that since I knew the battle would prolong till the end. There are too many deaths happening around me that I, who had fought over a hundred battles, started to feel suffocated.

I am not the only that is feeling that; many people are feeling suffocated seeing so much death, but they could not do anything but fight like an emotionless machine if we did not fight with our all, the Grimm Monsters, and seeing they still have a higher number than us, it will take them minutes to flip the trend of the battle.

Any human on the battlefield did not want to see it happen, so they are fighting. Despite knowing more people will die, holding back even slightly will result in grim consequences for all humans.

My team and I also killing any Grimm Monsters we are coming across; with the constant fighting of the two days, we are quite tired and liked to sleep, but we could not; there are still millions of Grimm Monsters present on the battlefield, and we have to kill them in considerable numbers to make them concede.

The special profession Grimm Monsters have become quite rare on the battlefield; we had to search across the battlefield before finding one. Instead of wasting too much time, we started to focus on stronger Grimm Monsters, who have a similar level of destructive power as Special Profession Grimm Monsters.

We target them; this way, we did not spend too much time tracking the special profession Grimm Monsters across the battlefield, but we always kept our senses active so that if we come across any Special Profession Grimm Monsters we would kill it first.

The afternoon came, and soon after the evening, the bodies of both Grimm Monsters and Humans littered across the battlefield, but there is no sign of battle ending could be seen.

Seeing so much death, I somehow have shut my emotions and continued fighting. If I had continued to see such deaths longer, I don't know whether I would have been able to remain sane or not.

"RETREAT!"

Suddenly at midnight, the word I was hoping to hear throughout the battle finally rang out through the Grimm Monsters mouth, and second, after that, they started to make a retreat.

I watched silently as the Grimm Monsters made the retreat, counting all three armies of them, Grimm Monsters have about twenty millions-strong fighters, and now only half of them have remained.

I looked at Grimm Monsters before turned toward our battlefield and bodies littered on the ground; massive numbers of bodies littered on the ground.

I was seeing bodies of hundreds of thousands of dead humans, near million. All the emotions I had been suppressing till now suddely burst out, breaking the dam that I had built to suppress them.

I felt all the death, and tears couldn't help but stream down my eyes. I never cried on the battlefield, but now I am crying; the flood of emotions I am feeling had been transformed into tears.

I rarely had any emotional outburst in my life but seeing so many deaths, it came, and I am in no position to stop it; hell, I am barely in a state of control of my own body.

On this deathly battlefield, I am riding an emotional rollercoaster, and I was drowning in the emotions of death present all around; I felt like I understood something about death.

I can't explain what it is in words as I could not find the current words for it, but I know I understood something profound, and just as I understood that thing, I felt a change in me.

It took me a moment to realize what that change is. It is my Killing Rule; it had leveled up from Intermediate Grade to Advanced Grade. 

The Ribbon inside growing and the blood-red glow that it used to exclude have become a little gloomy like a death.

The Killing is Rule is an offshoot of Supreme Death, so I am not surprised that my Rule advanced when I understood something about death; my killing rule had advanced immediately, but the advancement did not make me happy.

I would have preferred if these deaths did not have happened; the deaths here are too much for me to be happy about my Rule advancements.

Feeling I should focus on something other than death, I looked at Ribbon growing inside my source. As it grows, it brought more power to my Killing Rule and some new abilities.

A few seconds later, the advancement stopped, and I get to see the full glory of my Advanced-Grade Killing Rule, and that moment, I wish, it had not been advanced.

Sensory powers of the Killing Rule have multiplied manifolds; I could see everything, hear everything, feel everything around me, especially Killing Intent and Death.

Before advancement, I used to feel death, but it was nothing compared to what I am feeling right now. If it had been trickle before, it floods right now; the overpowering feeling of death had overwhelmed me so much that I had to clutch my head tightly.

It had taken me a while to get control over myself, and I saw myself on the floor with my teammates calling my name worriedly.

"I am fine," I said in a raspy voice as I got up, and when I look at them, I saw some shadowy or gloomy darkness around them. Not only them but all the humans around me have it.

'Death Imprint,' I thought inside me when I looked at the darkness that is enveloping them. I know what it is instinctively; I did not even have to think about it.

The darkness represents the people they have killed, and the more they killed, the darker will dark mist around them.
