Nil blur into motion appearing next to the undead in the next instant, and before the undead could register the movement it's form have started crumbling as Nil have dislodge it's core from wherever it is position.
[Ding!]
[You have kill an undead human at the 7th stage of Liquid gathering realm.]
And as soon as the rest of the undead sense an intruder among their midst.
They stirred.
Not just one undead moving at Nil, but the whole grave stirred— undead humans at various cultivation level, ranging from the 1st stage of Liquid gathering realm to the peak of Liquid gathering realm all lunged at Nil.
Not only undead humans, but also undead beasts, which Nil suppose are the mount of the dead warriors.
Beast of various race, horse being be most abundant among them, ranging in the hundreds.
And it is the beasts that first reach Nil, attacking him with their dreadful claw.
"What a delightful experience this will be." Nil smiled and then he is not at where he was before.
Dissolving into the shadow with [Form] coupled with the skill [Charge], he blurred.
Not out of sight of the undeads.
But into the shadow.
And before the beast could try to comprehend Nil movement, he is already beside them.
And immediately he appear beside them, they are not whole again.
Before he fully dissolve into the shadow, he have activate see, peering into each of the undead body, locating their core each.
And before he even fully rise out of the shadow, he have dislodge their core from their body and in less than a heartbeat they fell.
Then one by one, the undeads fell.
One falling in the heart of the battlefield, in the next moment another falling right at the rim of the battlefield, and the next moment another falling at the far back of the battlefield.
He did not just slaughter at one position, but at everywhere in what seem like once.
If a mundane mundane human is watching the battle right now, they would have thought they are many people fighting the undead at once because of the speed Nil is weaving through the battlefield.
And on the slaughter continues, then the undead bled.
But they did not bleed blood.
Blood is something the undeads have lost a long, long time ago.
So they bled the next closest thing to blood.
They bled their bones.
The battlefield turned into one made of bone.
And as numerous more undead ran at Nil, they inadvertently trample over their fallen friends, trampling the rest of their fragile bone into dust.
Fine dust, in fact.
Among the beast that are running in Nil direction, one of them suddenly step on one of the fallen undead bones and stumble to the side.
Using that moment of disorientation, Nil step out of the shadow beside it and before the nearby undead could register Nil, he have step into the shadow again, disappearing from their view.
Leaving the corpse of the beast he came for in his wake.
As Nil was teleporting all across the battlefield, he was creating another intended effect.
Disorderliness.
Once he teleport to one location, the beast will all run to that location, and after doing his deed there he would instantly step into the shadow and appear in another location which will make the mindless undeads abandon their previous pursuit and start running in the new direction they sense Nil.
Truly, a senseless beast they are.
And like that, Nil continued weaving through the battlefield, leaving chaos in his wake.
"I don't think I will be able to win this battle at this rate." Nil mumble at one point as he is inside the shadow.
Not long after Nil have that thought, when Nil was about to dissolve into the shadow again.
He suddenly felt that he is not alone in the shadow anymore, that someone has follow him.
And as someone that does not ignore his intuition, he peered into the shadow, and there he saw it.
Standing a couple of meter away from him, which is not really a distance since the entity can reach his position in an instant.
The law that govern the shadow realm is not that of the material realm.
The entity that follow him into the shadow is a humanoid being, completely composed of skeleton holding a dagger in one hand whereas its left hand seems to be shattered.
And, no flesh could be sighted on its being.
Except for the physical details Nil could discern with his physical eyes, he couldn't see anything else, so he activated a skill.
[Ding!]
[Skill See activated.]
[Beast profile.]
[Beast name: Unnamed.]
[Beast bloodline: Undead human (Mortal rank)]
[Beast title: None]
[Beast mana core rank: 3rd stage of Liquid Crystallization realm.]
[Beast racial skill: Corrupt, Decay touch, shadow transverse, shadow manipulation.]
[Lore: A dead human turned into an undead by lord of the 8th demonic realm after dying on the battlefield.]
"So, you were part of the Peak Shadow before dying on the battlefield."
Nil pieced together after seeing the undead having shadow type skills which could only suggest that the undead was part of Peak Shadow when he was alive.
The beast being at the 3rd stage of Liquid Crystallization realm is something to be concerned of.
That is if they were in the surface.
"But man, you had to follow me to the shadow dimension.
That's a gross mistake."
The undead did not wait for Nil to complete his sentence and lunge at Nil.
Not physically, but by manipulating the shadows in such a way that he weaved shadows the size of thread and choke Nil with it.
However, that is a futile action.
Without even bothering to acknowledge the thread as a threat.
Nil dismiss them, and instantly they dissolve into harmless plain shadow.
When the undead saw that Nil negate it's attack easily, he manipulated the shadow again, trying to weave then into deadly projectiles but couldn't.
Nil have already order the shadow to refuse any command the undead give them.
After realizing that it couldn't manipulate the shadow again, the undead then dash at Nil trying to attack him physically.
Then did it realize that the shadows have completely bound it's leg, it's arm.
Not leaving any part of his body, they have bound him to the position he stood at.
"Wait here for me, I have some pests to deal with." Nil disappear from the shadow realm after securing the undead shadow in tight bonds.
At the end of the day it's skill shadow transverse fail him too as it could not leave the shadow realm.
