Sword Master Feng and Sword Master Chen exchanged glances, both seeing the solemn expression in the other's eyes. They were well aware of the Undying Demon Lord's combat strength, and his hasty arrival this time was certainly for the Seal beneath the Nether Water.
A great battle was inevitable!
"Yun Jian, you take Elder Li and leave first." Sword Master Feng looked at Fang Yunjian, ordering seriously.
Li Mu could now refine Seven-Order Dao Weapons. If anything were to happen to an Artifact Refiner of this Rank, it would be an incalculable loss for Xuantian Sword Sect.
Fang Yunjian nodded in agreement, pulled the still-stunned Li Mu, and flew off in the opposite direction on his sword.
In the sky, the fleet led by the Undying Demon Lord was getting closer and closer. Rolling Devilish Qi seemed to obscure the entire sky. Sword Master Feng and Sword Master Chen smiled at each other, their Sword Qi crisscrossing as they prepared for battle.
At this moment, Li Mu, who was being rapidly evacuated by Fang Yunjian, looked back and saw the two Sword Masters standing like two mountains on the spot, their Sword Intent soaring into the sky, as if to tear apart the rolling Devilish Qi.
On the flagship's deck, the Undying Demon Lord's gaze was like a knife. He scanned the crowd below, and suddenly, his gaze fixed on Li Mu, who was being rapidly evacuated by Fang Yunjian. He remembered that face too clearly.
Back then, when he led his forces to launch a war of annihilation against Qingxuan Sect, he was defeated by a Cultivator who had just passed the Nascent Soul Tribulation, losing his armor and weapons, and his Physical Body was completely destroyed. If it weren't for his great fortune in gaining the favor of the Eternal Demonic God, becoming a Demonic Body, and cultivating the Undying Demonic Technique, he wouldn't be where he was today.
Recalling the past, the Undying Demon Lord's anger flared even more. Now that they met again, that Cultivator must not be let go.
"Leave him to me!" The Undying Demon Lord roared, his voice shaking the nine heavens: "This time, let's see how you die!"
With that, the Undying Demon Lord's figure flickered, transforming into a black light, and he directly pursued Li Mu. His speed was astonishing.
Sword Master Feng and Sword Master Chen saw this, and a hint of solemnity flashed in their eyes. They knew that if the Undying Demon Lord caught up to Li Mu, the consequences would be unimaginable.
At the same time, they were also quite curious as to why Li Mu, with his mere Soul Transformation Middle Stage cultivation, could provoke the Undying Demon Lord to such a deep-seated hatred, wishing to tear him into pieces immediately.
"Stop him!" Sword Master Feng roared, and together with Sword Master Chen, they transformed into two streaks of Sword light, heading to confront the Undying Demon Lord.
In the sky, a gold, a green, and a black stream of light suddenly collided violently in the air, and a great battle erupted.
Sword Master Feng's figure was like the wind. His Wind Sword Domain unfolded, and green Sword Qi crisscrossed, as if a strong wind had risen, forming a wind battlefield. Every wisp of Sword Qi was like a sharp hurricane, cutting through space and pressing towards the Undying Demon Lord.
At the same time, the spirit sword in Sword Master Chen's hand shone with a golden light. The Gold Sword Domain descended like a scorching sun, and brilliant Sword light enveloped all directions. Golden Sword Qi, like golden Giant Dragons, roared and charged towards the Undying Demon Lord, seemingly wanting to completely engulf him.
Facing the encirclement of the two great Sword Domains, the Undying Demon Lord showed no fear on his face. He sneered, and black Devilish Qi surged around him, forming an Immortal Devil Domain, resisting the attacks from Sword Master Feng and Sword Master Chen. The Devilish Qi, as if alive, transformed into various forms under the Demon Lord's control, fiercely colliding with the two great Sword Domains.
"Undying Demonic Art!" The Undying Demon Lord roared, and the Undying Demon Qi all over his body suddenly became even denser, as if night had fallen, obscuring the entire sky. In this dense Devilish Qi, the Undying Demon Lord was like a Demonic God descended, unrivaled.
Sword Master Feng and Sword Master Chen couldn't help but look solemn. The Undying Demon Lord's Undying Demonic Art was no small matter; a slight carelessness could lead to a backlash. But at this moment, they had no retreat and could only fight the Undying Demon Lord with all their might until the end.
Green and golden Sword Qi intertwined, forming powerful Sword currents that launched an even more ferocious assault on the Undying Demon Qi. In the sky, the two Sword Domains and the Devilish Qi collided violently, producing deafening roars. The battle had just begun and had already entered a white-hot stage.
"Loser, get lost!" The Undying Demon Lord waved his hand, unleashing a stream of Undying Demon Qi that transformed into a black Dragon, sending Sword Master Feng flying.
Sword Master Feng tumbled several times in the air before barely stabilizing his figure, his Sword Intent becoming even more solid.
Sword Master Chen roared, and the Gold Sword Domain suddenly erupted. Countless golden Sword Qi converged into a giant golden Sword shadow, fiercely slashing towards the Undying Demon Lord.
The Undying Demon Lord sneered, his Undying Demon Qi surging, easily blocking that sword. He glanced at the repelled Sword Master Feng and mocked: "Is that all you're capable of? Still want to stop me?"
Sword Master Feng ignored the Undying Demon Lord's sarcasm and once again activated the Wind Sword Domain. This time, his Sword Qi was even sharper, and countless green winds formed streaks of Sword shadows across the sky.
Sword Master Chen cooperated with him, and relying on the compatibility of their Sword Domains, they unleashed several times their combat power, bringing no small amount of trouble to the Undying Demon Lord.
A hint of impatience flashed in the Undying Demon Lord's eyes. Seeing his old enemy, he wished he could capture him immediately, but he was entangled by these two guys. He decided to end the battle quickly and deal with these two troublesome fellows first.
The Undying Demon Lord calmed down and fully activated the Undying Demonic Art. Devilish Qi surged around him, forming black whirlpools. These whirlpools emitted a powerful devouring force, attempting to drag the two Sword Masters into them.
However, Sword Master Feng and Sword Master Chen were not ordinary individuals. They each displayed their unique techniques, skillfully evading the whirlpools' devouring power, and seizing the opportunity to launch counterattacks. For a moment, Sword Qi and Devilish Qi intertwined in the air, forming a spectacular picture.
In a short while, the two Sword Masters combined forces and exchanged thousands of blows with the Undying Demon Lord, but they remained in a stalemate, unable to determine a victor.
Sword Master Chen and Sword Master Feng exchanged glances. They cooperated tacitly, jointly unleashing their ultimate technique—the Combined Sword Art!
In an instant, the two Sword Domains merged into one, transforming into a brilliant Sword glow that slashed towards the Undying Demon Lord with lightning speed. The power of this sword was so immense that even space seemed to be torn apart.
The Undying Demon Lord felt this powerful Sword Qi, and a solemn expression finally appeared on his face. Not daring to be careless, he fully activated the Undying Demonic Art to resist.
"Boom!" A loud sound echoed, shaking the entire sky. When the dust settled, the Undying Demon Lord's Immortal Demon Armor was completely unharmed; he had only been forced back a few steps.
Sword Master Chen and Sword Master Feng's expressions were solemn. Compared to a few years ago, the Undying Demon Lord's Demonic Technique was even more profound. Their combined sword strike was actually unable to break through the Demonic Armor he wore.
"Haha! You think you can break my Demonic Armor with just that? What a pipe dream!" The Undying Demon Lord laughed wildly, his voice shaking the heavens and earth.
The Demonic Armor on the Undying Demon Lord's body shimmered with a cold, eerie light in the sunlight. After a surge of Devilish Qi, the sword wound left by that incredibly powerful sword on the Demonic Armor instantly healed, returning to its original state.
Seeing this, Sword Master Feng and Sword Master Chen's expressions simultaneously darkened.
The Undying Demonic Art cultivated by the Undying Demon Lord was closely related to the Demonic Armor on his body. When the Demonic Technique operated, the Demonic Armor could automatically repair any damage it sustained, which almost made the Undying Demon Lord invincible in battle.
"What should we do?" Sword Master Feng asked telepathically with a deep voice. He clearly hadn't expected the Undying Demon Lord's strength to reach such a degree.
A hint of determination flashed in Sword Master Chen's eyes. He replied telepathically, "There's a method we can try. You cover me, and I'll attack his unarmored vital points."
Sword Master Feng nodded upon hearing this. This might be their only chance at the moment.
Thus, the battle resumed. Sword Master Feng moved around the periphery, distracting the Undying Demon Lord, while Sword Master Chen secretly accumulated strength, looking for an opportunity.
Finally, under the cover of a fierce exchange between Sword Master Feng and the Undying Demon Lord, Sword Master Chen seized the opportunity, his figure flashing, and he struck fiercely at the Undying Demon Lord's neck with lightning speed.
"Swish!" With a soft sound, Sword Master Chen's long sword pierced towards the Undying Demon Lord's neck like lightning.
For a moment, time seemed to stand still, and both their gazes were focused on this single sword strike.
"Pfft!" With a muffled sound, Sword Master Chen's long sword actually struck the Undying Demon Lord's neck, and a gush of blood spurted out. However, the Undying Demon Lord did not fall; he waved his hand, sending out a stream of Undying Demon Qi that sent Sword Master Chen flying.
He hadn't expected this attack to actually succeed.
But what shocked the two Sword Masters even more happened. The Undying Demon Armor on the Undying Demon Lord's body once again shimmered with a cold, eerie light. After a surge of Devilish Qi, the wound on his neck miraculously healed!
"This... how is this possible?!" Sword Master Feng exclaimed.
The Undying Demon Lord, however, showed a sinister smile: "You think you can defeat me like this? How ridiculous! My Undying Demonic Art has been cultivated to its extreme; I am immortal and indestructible. You can't kill me!"
After speaking, the Undying Demon Lord suddenly waved his hand, and a powerful surge of Devilish Qi swept towards the two of them. Sword Master Chen and Sword Master Feng hurriedly swung their swords to block, but they were still sent flying backward.
Sword Master Feng stared at the Immortal Demon Armor on the Undying Demon Lord's body, as if he had discovered a clue, and also understood the reason for the Undying Demon Lord's immortality.
A flash of realization crossed Sword Master Feng's eyes. He said in a deep voice, "I understand now. This Immortal Demon Armor is not an ordinary protective armor; it is actually closely connected to the Undying Demon Lord's Demonic Technique, almost becoming a part of his body. Whenever he is injured, the Demonic Armor will automatically repair itself with the power of the Demonic Technique, making him virtually invincible in battle."
Sword Master Chen frowned upon hearing this: "In that case, aren't we helpless against him?"
Sword Master Feng shook his head and said, "Not entirely. Although the Immortal Demon Armor can automatically repair itself, the operation of the Demonic Technique will inevitably consume a large amount of Devilish Qi. As long as we continuously attack and deplete his Devilish Qi, we might find a Breakthrough."
The Undying Demon Lord couldn't help but laugh loudly upon hearing their conversation: "You think you can exhaust my Devilish Qi like this? How naive! My Devilish Qi is endless; you will never exhaust it!"
With that, the Undying Demon Lord launched another fierce attack, his Devilish Qi surging, as if to engulf the two of them.
However, Sword Master Feng and Sword Master Chen did not retreat and continued their entanglement with the Undying Demon Lord.
For a time, Sword Qi and Devilish Qi filled the sky over the Nether Water Sea Domain, and the heavens and earth changed color.
This battle lasted for a long time, and both sides gave their all, but Sword Master Feng and Sword Master Chen gradually realized that the Undying Demon Qi emanating from the Undying Demon Lord showed no signs of weakening, as if it were endless and inexhaustible.
"No! This Demonic Armor, combined with his Demonic Technique, makes the Undying Demon Qi inexhaustible." Sword Master Feng asked Sword Master Chen telepathically. He hadn't expected the Undying Demon Lord's strength to reach such a degree.
"There's no other way. Prepare to retreat! If Elder Li can help us refine a Dao Sword, then taking down this fiend with a Dao Sword in hand will be effortless." Sword Master Chen replied telepathically.
"It can only be so!" Sword Master Feng nodded in agreement, responding.
Thus, the two Sword Masters began to change their tactics, no longer attacking fiercely, but adopting a strategy of skirmishing and harassment. Instead, they adopted a defensive stance, fighting and retreating, preparing to disengage and escape. Their sword techniques were exquisite, and their movements were agile. Although their attack power was greatly reduced, they prevented the Undying Demon Lord from easily defeating them.
The Undying Demon Lord was quite annoyed by this tactic. He tried to capture them multiple times but was easily blocked by their close cooperation. Undying Demon Qi surged from his Immortal Demon Armor, and the Undying Demonic Art operated at full power, transforming into Demonic Hands attempting to capture them, but each time they returned empty-handed.
"You two cowards, can you only hide and sneak around?" The Undying Demon Lord roared loudly, his Devilish Qi surging, clearly enraged by this delaying tactic.
However, Sword Master Feng and Sword Master Chen acted as if they hadn't heard him, continuing their tactics, preparing to disengage and retreat. The Demonic Armor on the Undying Demon Lord was too overbearing; they found it difficult to inflict fatal damage on him.
Only when Li Mu refined a Dao Sword for them would it be the time to slay this fiend.
The battle continued, but the situation on the field had clearly changed. The two Sword Masters used defense as offense. Although they were at a disadvantage, they were never defeated by the Undying Demon Lord. And although the Undying Demon Lord's attacks were like a tide, he was always unable to break through the opponent's defense, which made him extremely frustrated.
Overwhelming Devilish Qi, rampant in the sea domain.
At this time, Fang Yunjian, riding a sixth-Rank spirit sword, had led Li Mu to escape ten thousand miles away from the Nether Water Sea Domain, and they could no longer see the vast aftershocks of the great battle between the Undying Demon Lord and the two Sword Masters.
"Elder Li, that Undying Demon Lord seems to recognize you. Do you have a grudge with him?"
Fang Yunjian's taut nerves relaxed, and he looked at Li Mu with a hint of curiosity, asking with concern.
Just now, he was standing next to Li Mu and felt the chilling killing intent that the Undying Demon Lord directed at him. That killing intent was completely aimed at Li Mu, as if Li Mu had a deep-seated hatred with him.
If it weren't for the two Sword Masters intervening in time to block for them, his Divine Soul would have been injured by that chilling killing intent.
Hearing Fang Yunjian's question, Li Mu's eyes flickered, and he gave a wry smile, nodding: "Indeed, I didn't expect him to become the Undying Demon Lord; it's truly unbelievable!"
Fang Yunjian silently watched Li Mu, waiting for him to continue.
"More than a hundred years ago, when he was still a Soul Transformation Cultivator, he tried to annihilate my Qingxuan Sect and was slain by me. I didn't expect that after he escaped, he would Cultivate such a Demonic Technique and even achieve the Combined Body Realm. Now, he is the Undying Demon Lord, and I am far from being his opponent!" Li Mu frowned deeply, speaking with apprehension.
"So that's how it is!" Fang Yunjian realized after hearing this. After a moment of silence, he suggested: "Elder Li, you are now targeted by the Undying Demon Lord. Why not return to the sect for temporary refuge? For a short period, it's best not to venture out of the sect!"
"It can only be so!" A hint of unwillingness flashed in Li Mu's eyes, and he nodded with a wry smile.
