In fact, Mitsuki was secretly sighing, realizing he had underestimated the power of this combo.
He had released the attack too early, failing to wait for more Hell demons to appear and cause greater casualties.
But outside the Dimensional Battlefield, unseen by him, the demons in the Hell Dimension who were clamoring just moments ago were now nearly scared to death.
Especially the row of demons on the edge of the Dimensional Battlefield, with one foot already stepping in.
The luckier ones might have just put a foot in while their upper bodies remained in the Hell Dimension.
The incoming "Reaper's Scythe," after shredding the demons in front of them, vanished before their eyes due to the battlefield's rules, transported to the Hextech Dimension.
At most, they were drenched in the blood and gore of the demons ahead.
But the unlucky bastards who had half their bodies in the battlefield were torn apart by the slash, dying instantly the moment they stepped in.
At this moment, in the Hell Dimension, the line symbolizing the Dimensional Battlefield boundary looked like the line between life and death to all the demons who hadn't crossed it yet.
Even though these demons were agents of chaos and disorder, biological instinct made them fear such cheap, meaningless death.
At this moment, many demons at the front who witnessed the Reaper's Scythe retreated slightly in fear.
However, demons were still demons.
After the initial fear, their chaotic nature once again occupied their undeveloped brains, and the roaring and howling resumed.
It was then, perhaps dissatisfied with the slow advance of his underlings, that a massive Flame Demon—over ten meters tall, with two horns on his head and a lower body with four legs like a centaur—impatiently waved his flaming greatsword and charged to the very front, trampling everything in his path.
Yes, his reckless charge and burning flames killed quite a few weaker demons on the spot.
But at least these demons died within the Hell Dimension, so Hell itself suffered no loss.
Of course, given their nature, even if they were on the Dimensional Battlefield, he wouldn't care about the deaths of fodder demons.
Back to the topic.
This Flame Demon Warlord, possessing more intelligence, had clearly seen the slaughter caused by Mitsuki's jutsu.
However, facing the ground littered with demon corpses, he showed no concern. Stepping on flames, he charged straight into the Dimensional Battlefield, galloping towards Mitsuki, who stood alone on the vast ground.
His action naturally spurred the other demons to charge even more recklessly.
Watching the demons pass through the ripple-like boundary and appear in his sight, Mitsuki, still standing in place, wasn't surprised.
If a single attack could stop the demon offensive, he would have underestimated dimensional warfare and the Hell Dimension itself.
Seeing countless demons charging again led by the giant Flame Demon...
This time, Mitsuki didn't use a wide-range attack to clear the fodder. Instead, he flashed backward, creating distance between himself and the incoming wave of demons.
After all, while blocking demons at the battlefield edge protected the base better...
Killing them all at the enemy line made recovering corpses difficult.
They would simply be digested by the Dimensional Battlefield, unavailable as materials for the "Grinder" to convert into resources for his side.
Of course, even if he retreated, Mitsuki wouldn't retreat all the way to his base.
Reactivating "Speed Force," Mitsuki retreated to the center of the battlefield in the blink of an eye.
Watching the giant Flame Demon chugging towards him, leaving a trail of explosions and sparks...
Mitsuki ignored the probing barrage fire Dunshan had started from the rear. After a moment of thought, he bit his finger and quickly formed hand seals, deploying a sealing array on the ground.
By the time Mitsuki finished drawing the array...
The Flame Demon Warlord, whose speed wasn't slow and had long left the demon army behind, was charging straight at Mitsuki, stepping on a long trail of scorched earth and waving his flaming greatsword.
Facing Mitsuki, who was crouched in a strange posture, the Flame Demon Warlord had no intention of slowing down.
Like a burning bull, carrying heat waves and momentum, he turned into a flaming meteor.
"Kneeling won't save you! Die, insect!"
Terrifying flames erupted abruptly. The massive demon, over ten meters tall, swung his sword down the moment he reached Mitsuki.
However, before the greatsword wreathed in hellfire could truly fall...
A demon that speaks human language? Pity, still brainless.
As the thought flashed, Mitsuki suddenly clapped his hands together.
The next moment.
"Cursed Seal of Self-Binding!"
Pitch-black sealing patterns rapidly covered the Flame Demon's entire body.
The Flame Demon Warlord, charging with the force of a thunderbolt, froze instantly, his greatsword held high, motionless.
Even the violently burning hellfire on his body couldn't shake the thin layer of seemingly insignificant black markings.
"Wh... what magic is this...?!!"
Subdued in a single encounter, the Flame Demon roared in anger with difficulty.
But Mitsuki, still crouched, ignored him completely. He calmly changed hand seals to activate another pre-set sealing jutsu.
"Fire Sealing Method!"
As his voice fell, a new array quietly appeared on the ground.
At the same time, the hellfire constantly erupting from the bound Flame Demon, trying to break the seal, was drawn like water by an invisible force, rapidly converging into the small black array pattern on the ground.
This seal seemed unreasonable, completely disregarding whether the ordinary ground could withstand so much hellfire.
It simply absorbed and stored it, the speed becoming more and more terrifying, eventually turning into a torrent of fire.
In an instant, the Flame Demon Warlord before him completely "extinguished" and dimmed.
"NO————"
Amidst a miserable shriek...
Just as Mitsuki prepared to finish off the defenseless Flame Demon, he was surprised to find...
Without the hellfire, the Flame Demon crumbled like dry, scorched earth, turning into a pile of warm ash in the blink of an eye.
Slowly retracting the "Pandora Greatsword" in his hand, Mitsuki looked at the massive number of demons surging forward like a flood.
With a rare chuckle, he flashed backward while throwing a kunai backhand, nailing it into the "Fire Sealing Method" array on the ground.
BOOM—
The sealed hellfire erupted explosively.
Countless follow-up demons were instantly reduced to ashes in the terrifying flames, equivalent to the self-destruction of a Flame Demon.
