Taixuan Sword God, also known as Edge of Taixuan: Divine Essence.
It is the ultimate move of Edge of Taixuan, possessing an unblockable characteristic. Its essence is a move that permeates the entire space, and the reason for this special attack method is due to the nature of Edge of Taixuan, which manipulates Honkai Energy outside the body.
The DanMachi world does not have Honkai Energy, so the original Edge of Taixuan could no longer be used.
During her treatment, Fu Hua modified the operation method of Edge of Taixuan based on the magic power she learned about in this world.
Its essence did not change much, but the Honkai Energy required for its operation was converted into magic power.
However, due to the scarcity of magic power in the atmosphere, even to use Edge of Taixuan, one would need to prepare a large amount of magic-containing substances themselves.
But upon seeing Nidhogg absorbing the dense magic particles around it, Takatsuki thought of Edge of Taixuan, which also manipulates external energy.
However, relying solely on Edge of Taixuan naturally wouldn't be able to outcompete this evil dragon.
"Although it's only theoretically usable, let's give it a try."
His bloodied arms assumed a circular embrace posture, and the surrounding magic power continuously gathered with Takatsuki's movements.
The pain from his arm injury could not affect Takatsuki.
Compared to the agony of being near death from Honkai Energy erosion, this was truly nothing.
"Divine, the extreme of change..."
As the words were uttered, the surrounding magic particles suddenly surged towards Takatsuki like a storm; even Nidhogg's absorption speed couldn't keep up with Takatsuki's speed of gathering magic power.
And Takatsuki's voice also spread with the surging magic power.
On the 13th Floor, Fu Hua had just defeated the bull-shaped monster. Hearing the voice, she looked up towards the ceiling, a slight smile of relief on her face.
On the 12th Floor, the Sword Princess, consumed by hatred, continuously clashed her Sword of Despair with Revis, who was encased in red fleshy armor.
Ever since Revis donned this armor, she seemed to have endless energy, instantly recovering from torn flesh and quickly restoring severed blades.
The entire Dungeon seemed to be her backing.
Meanwhile, Ais's magic power and stamina were constantly depleting.
Even with the strongest Revenge Princess, this ominous power, driven by hatred, grew stronger with hatred but also continuously consumed her own life force.
It wouldn't be long before Ais would burn herself out, just like the wailing Sword of Despair in her hand.
Even the sword, possessing the attribute of immortality, was now covered in cracks, on the verge of shattering.
"Subtly speaking of all things..."
A familiar voice entered Ais's ears, which were clouded by hatred.
"Teacher…"
Ais, who was immersed in battle, instantly sobered up.
"What am I doing…"
The girl, who had severed her connection with the world due to hatred, reconnected with it.
"What's wrong! Keep going!"
Revis mocked Ais, who had stopped her continuous attacks.
But Ais was indifferent to her mockery.
"What should I do?"
Ais knew that with her current strength, she couldn't defeat the enemy in front of her, but the opponent was an obstacle she had to overcome.
"Do not question the form!"
Listening to the completed chant, she felt the surrounding magic particles beginning to flow.
"God is the ultimate of change, speaking of myriad things wonderfully, not to be questioned by form… I understand, Teacher."
No one knew what Ais understood in that instant.
The black karmic flames instantly vanished as if extinguished.
The black hurricane transformed into the familiar Spirit Wind.
"Hey! What do you mean! Not fighting anymore!"
No sooner had Revis voiced her dissatisfaction than she saw Ais in front of her raise her head. The black gleam in her eyes had disappeared, but the will contained within them had not weakened in the slightest.
The fighting spirit had not vanished; it had merely hidden deeper.
Instantly, Ais disappeared.
"What!"
Revis instantly raised her sword to block in front of her. The moment she raised it, a silver-white rapier struck her sword.
And the moment they collided, both swords shattered simultaneously. The Sword of Despair, which had accompanied Ais for a long time and possessed the property of indestructibility, finally broke in such a fierce battle.
"Ha! You have no weapon, and my…"
Just as Revis was about to repeat her trick of drawing a weapon from the green flesh, she saw Ais's hand enveloped in a black layer, which then pierced her body.
"Nani!"
Rip!
A familiar Magic Stone was pulled out by Ais and then shattered in her hand.
"How… could this be…"
The monster whose Magic Stone was pulled out, like other monsters, would instantly turn to dust.
Looking at the spot where Revis disappeared, Ais picked up the scattered fragments of the Sword of Despair.
"Thank you, Teacher."
Meanwhile, on the 13th Floor… after the chant, a golden greatsword appeared in mid-air.
"Edge of Taixuan · Divine Essence!"
The golden greatsword thrust towards Nidhogg.
"Can you block this sword!?"
Nidhogg also unleashed its strongest attack towards the incoming greatsword.
But was it useful?
The answer was clear. Although it had the shape of a sword and was called Taixuan Sword God, it actually used the entire space as a means of attack, and a segment of Taixuan Sword God's attack was not physical damage but a spiritual attack.
As long as one could not withstand the spiritual attack of one segment, one could absolutely not defend against Taixuan Sword God's attack.
This was the secret of Taixuan Sword God's undefendability.
Only once, with Sirin, the Will of Honkai helped Sirin block a segment of the spiritual attack, thus saving her.
Nidhogg's breath, when facing Taixuan Sword God, was like a flame striking a hammer; it left no trace and was completely swallowed by Taixuan Sword God, becoming part of the attack on Nidhogg.
In terms of controlling surrounding energy, nothing present could compare to Takatsuki, or rather, Taixuan Sword God.
After all, Nidhogg merely absorbed Magic Power Emission, while Taixuan Sword God actually changed its nature, forming an omnipresent attack.
The golden greatsword pierced Nidhogg's body. The result was beyond doubt; Nidhogg was cut down by Taixuan Sword God without suspense, and the Magic Stone on its body was also pulverized.
Watching Nidhogg completely disappear, Takatsuki finally breathed a sigh of relief.
"It's finally over… now…"
A wave of fatigue suddenly surged into his heart.
How could Taixuan Sword God, with its powerful spiritual attack, only need to consume surrounding energy? The mental effort required by its main body was also exaggerated.
"Takatsuki-kun!"
As Takatsuki fell into the large hole, a figure rushed over and held him in her arms.
Mei looked at Takatsuki, who had fallen into a deep sleep in her arms, and sighed in relief.
"You worked hard, get some good rest…"
