A faint yellow light flashed on the mountain wall, and a young figure emerged. There was a faint smile on the familiar face, it was Sun Xiaofei himself. The attack just now was just that he wanted to test the other party's reality, Sun Xiaofei glanced at those people of the Underworld Sect, and then snorted coldly, his mind moved slightly, and an astonishing number of swords instantly condensed and shot towards those people of the Underworld Sect.

In an instant, the screams and exclamations were endless, and those lowly Underworld Sect disciples were unable to resist Jian Gang's fierce attack at all, and they died one after another. Only a part of the strong men with rich combat experience and strong strength will be able to resist it.

The old man turned a blind eye to what was happening in front of him. His expression was focused, single-mindedly summoning the Undead King of the Otherworld. At this time, he didn't dare to be distracted in the slightest, if this undead magic was not successful, the backlash would be unbearable for him.

Therefore, even if he knew that Sun Xiaofei had already appeared, he could only wait, suppress the impatient thoughts, summon the Undead King as soon as possible, and use it to deal with Sun Xiaofei.

Sun Xiaofei frowned and watched the old man's actions, and from the crack in the ground below, he sensed an extremely terrifying fluctuation of death aura. Sun Xiaofei realized that he had to hurry up and stop the Immortal Elder from continuing to summon the undead, and if the Immortal Elder succeeded in bringing the Undead King out, it would bring great threats and troubles to his operation.

Sun Xiaofei naturally couldn't let him get his wish so easily, his eyes were cold and his heart changed, the power of the five elements was mysteriously transformed, and all kinds of magical and powerful attacks ruthlessly slaughtered those people in the Underworld Sect.

People who fall into the power of the five elements are all attacked by the power of the five elements, and the power of the five elements restrains each other, and the cycle never ends. Amazing soul fluctuations poured out of Sun Xiaofei's body, and the entire cave was shrouded in spiritual power, and the invisible coercion made people's souls difficult to resist, and some people couldn't bear it and were almost crushed, Sun Xiaofei's terrifying strength was exposed.

The power of the five elements changes at will, and between the changes of the handprints, the cold and soft water power, the tough wood power, and the thick and heavy earth power cooperate with each other to restrain their actions. The raging blazing flames, filled with the power of the gold system, and the sharp sword gang gave them a great threat...... The ever-changing attack force made it impossible for the people of the Underworld Sect to adapt to it, and they were unable to form a tight and solid defense at all.

In just a few moments, nearly half of the people were killed by Sun Xiaofei. The screams continued to sound, and those Underworld powerhouses who had survived Sun Xiaofei's attack all gathered around the Immortal Elder. Because they knew very well that with the strength of their people, they would not be able to resist Sun Xiaofei, a fierce god.

The Immortal Elder was indifferent to the casualties of his men, his face did not change, he had already vaguely seen the undead king who had crossed the border from the underground, and he was about to come out. Some of the Netherworld's powerhouses protected the periphery against Sun Xiaofei's attacks, and several necromancers summoned the undead to deal with Sun Xiaofei's attack with a huge number of undead.

I only saw one undead after another emerging from the ground, most of the undead were not weak, and if they were placed outside, they would definitely set off another bloody storm. However, now here can only be reduced to cannon fodder to resist Sun Xiaofei's offensive.

When Sun Xiaofei saw this scene, he felt a headache in his heart. Fight against a mage who practices necromancer, and if you can't deal with each other as soon as possible, the latter will summon a staggering number of undead legions, trapping people inside and dying with all their strength.

Sun Xiaofei no longer concealed his true cultivation, the light flashed in his hand, the Sky Sword appeared in his hand, and the other hand quickly pinched the trick and tapped at the underworld powerhouse in front of him. I saw that the aura of heaven and earth around him suddenly boiled, merging with the power of the five elements, forming a huge giant lion with a huge body and a mighty demeanor.

The giant lion let out a roar, and the invisible sonic impact spread instantly, and those Nether Sect powerhouses and a large number of undead came into contact with it, and their bodies trembled suddenly, with a soft click, and their souls were fragile and shattered like a porcelain bottle.

The giant lion's figure suddenly blurred, and the next moment it appeared in the crowd, and with a bang, its body changed dozens of slightly smaller golden lions, each of which pounced towards a Nether Sect powerhouse. This change came very suddenly, whether it was those powerhouses who were trying their best to resist or unleash the undead magic, they did not expect Sun Xiaofei to have such an attack.

The mysterious runes emerged, sealing the magic recipe nine-character true recipe Dafa seal, fusing the power of the five elements, and bursting out with irresistible power. Everyone's bodies and souls were imprisoned at this moment, unable to move and let Sun Xiaofei attack.

"Broken heart and hatred!" Sun Xiaofei unleashed the sword move of the Rainbow Sword Technique, full of grievances and sad artistic conceptions, which made people feel unbearable to resist.

The misty sword light is like a dream, but it brings terrifying power, and if it is hit, it will be a shattered end. Seeing this, the old man didn't dare to be careless, and immediately urged the magic power to condense a bone wall in front of him. The bone wall was covered with dense skulls and screamed terrifyingly, making people's scalps tingle when they heard it.

"Snort!" The sword stabbed on the bone wall, and many skeleton skulls burst in response, and suddenly the bone wall sank, and the surrounding skulls surged wildly, chewing and devouring the true yuan power contained in the sword.

Sun Xiaofei could clearly sense that the power in the sword light he emitted was disappearing rapidly. Sun Xiaofei frowned, his attack methods were not limited to this, and then he opened his mouth and shouted: "Explosion!"

"Boom!" the sword light shot around, tearing a huge hole in the bone wall. The violent power gushed out from it, Sun Xiaofei's eyes looked through this crack, his face was cold, he didn't have a good impression of the people of the Underworld Sect, the relationship between the Underworld Elder and Reeves, Sun Xiaofei naturally would not let him go easily.

"Go!"

Almost when Sun Xiaofei's attack tore through the bone wall, Sun Xiaofei's hands pinched it, and the Sky Sword turned into a streamer and shot out, the old man was shocked when he saw this, the bone wall he had condensed just now was already the strongest defensive force he could play, and now in the face of the more terrifying power of the flying sword spirit treasure, how could he deal with it?

"Roar ......!"

Suddenly, Sun Xiaofei's heart skipped a slight beat, and he felt an astonishing fluctuation appear, and the terrifying Undead King finally appeared in his field of vision at this moment.

The Undead Monarch's huge mouth bit the Sky Sword, but after Sun Xiaofei's refining several times, the quality of the Sky Sword has now reached the level of a spirit treasure, and it is not easy for the Undead Monarch to destroy it. The rich aura of death permeated the sky, eroding the spirituality of the Sky Sword.

Disheveled...... Sun Xiaofei saw that the flying sword attack was blocked, and he manipulated the Sky Sword to break free from the Undead Monarch and fly back into his hand. In just a moment, the Sky Sword was eroded by the power of death, the luster of the sword body dimmed, and the true yuan power contained in it was consumed.

Sun Xiaofei stretched out his hand, and the Sky Sword seemed to be re-empowered, and it glowed with dazzling brilliance. After doing this, Sun Xiaofei turned his head to look at the old man, and his eyes narrowed slightly at the Undead King.

The Undead Monarch was tall, breaking through the ground with his head on the top of the cave, his entire body was made of hard bones, covered with a thick layer of bone-like scales, and the soul fireworks that danced in his two eye sockets were turquoise,

"Kill him for me. The Elder slashed his fingers, squeezed out a few drops of essence blood and put them into the mouth of the Undead King to sacrifice, and then pointed at Sun Xiaofei.

"Roar!" the Undead King received the sacrifice of the Immortal Age's blood, and the red light on his body flickered, and the soul flames in his eyes beat even more violently. Yang Tian let out a loud roar, and then took a step with a rumbling sound, and rushed towards Sun Xiaofei with a terrifying sound.

Seeing this, Sun Xiaofei was secretly surprised. I didn't expect this Undead Monarch to have such amazing power once he attacked. However, he is not afraid of anything. Sun Xiaofei has hole cards that can deal with such a strong existence. His current strength is no longer the same as that of Wuxia Ameng in the past, and he will not have the slightest panic because of this.

Sun Xiaofei's mind turned, and he already had a way to deal with it, and under the pinching of his hands, five battle swords burst out from the sword heart space of the Sky Sword one after another, suspended around him, and the different five elements of gold, wood, water, fire, and earth appeared in the sword body, and each war sword had amazing fluctuations emanating out.

"Five Elements Sword Formation, Condensation!"

With Sun Xiaofei snorting, the dazzling imprints of change on his hands, the five battle swords disappeared in a flash, and disappeared into the void.

The next moment, five battle swords flashed beside the Undead Monarch, forming a mysterious sword formation at once, and the power of the five elements was endless, erupting with terrifying power, trapping it in it.

The old man looked at this scene with a solemn face, at this time he had no way out, since he and Sun Xiaofei had met, it was impossible for the latter to let him go. There must be a break between him and Sun Xiaofei.

The victory or defeat of the King of the Dead is a matter of life and death. The elder knew that if he couldn't keep Sun Xiaofei behind, the result waiting for him would be only death.

Naturally, the old man would not sit still, he condensed all kinds of magic attacks and bombarded Sun Xiaofei, trying to contain his attack power, so that the Undead Monarch had a chance to harm Sun Xiaofei. It's just that his attack, in the face of the sword formation derived from the power of the five elements, can't shake it in the slightest.

The Undead King was trapped by the sword array, unable to break out, and its attack shook the sword array. The sword array formed by the power of the five elements, each sword burst out with terrifying power, completely suppressing the power of the Undead Monarch. Sun Xiaofei used the power of the magic seal of the nine-character true technique, and it was difficult for the Undead Monarch to break through the sword formation.

Sun Xiaofei's current cultivation has skyrocketed much compared to what he did before, even in the face of a saint-rank powerhouse, he is confident that he will get out safely. If you use all means and magic weapons, you will be able to fight with the powerhouses at the peak of the Holy Rank. His current cultivation is between the late Yuan Infant stage and the Transformation Stage, but the strength he exerts in real battle is much more powerful than that of ordinary Transformation Stage monks.

Sun Xiaofei's figure disappeared suddenly, and in the next moment, he appeared on the other side of the sword array, crossed the Undead King and attacked the Immortal Elder, with a flick of his wrist, the sword gang shot out from the Sky Sword Burst. Several Underworld Sect powerhouses who were close to the Immortal Elder, and before Sun Xiaofei could react, they were shot and killed by the sharp sword gang at the moment Sun Xiaofei appeared.

For these characters that have nothing to do with the overall situation, Sun Xiaofei doesn't care at all. His eyes were fixed on the old man, and with the assistance of the nine-character Dafa seal, the Rainbow Sword Technique launched a fierce offensive, the sword moves were fast or slow, and the sword and sword did not leave the vital points of the old man's body, forcing the old man to deal with it in a hurry, trying his best to distance himself from him.

There is nothing that people who practice magic fear more than to be approached by an enemy in close quarters. As we all know, magicians generally have a weak physique, which is not suitable for hand-to-hand combat. They are even better at chanting spells from a distance, gracefully unleashing all kinds of powerful magic to bombard their enemies.

Seeing Sun Xiaofei using his sword move to attack, the old man immediately dodged and retreated, the bone wall just now couldn't resist Sun Xiaofei's attack, how dare he take it face to face. A burst of black mist appeared for no reason, obscuring the figure of the old man, and the latter's body turned into several swift black smokes, and swept away towards the surroundings.
