In a flash, Wu Sen changed into a tall human-shaped demonic beast.
Wu Sen was now over three meters tall and had gruesome ink-black hair that looked like steel needles.
His hands changed into wolf claws. His ten sharp fingernails were each more than 33 cm long.
His face also changed a lot. Although it had not completely changed into a wolf head, it was ferocious and terrifying.
"Beast transformation?" Su Mo squinted slightly as he stared at Wu Sen. The other party had clearly become beast-like.
However, he knew it was not simply beast transformation because he felt Wu Sen's aura skyrocketing.
This was a substantial change. Wu Sen's strength had increased to a great extent.
"Su Mo, I will now show you the difference between you and a Martial Emperor."
Wu Sen shouted coldly and then stepped in the void. He strode toward Su Mo, covering more than 3,000 meters with each step.
Su Mo looked solemn. The 24 Natal Spiritual Swords revolved around him like spiritual snakes that were ready to launch fierce attacks.
Thud! Thud! Thud!
Wu Sen's every step made a muted thud. The void under his feet collapsed and cracked, creating huge black holes.
Soon, Wu Sen was less than 5 km away from Su Mo.
This time, Su Mo struck first. He wouldn't stand around and wait to be attacked.
With that in mind, the 24 Natal Spiritual Swords immediately shot forward. The 24 Constellations Sword Formation was arranged, enveloping Wu Sen.
With a straight face, Wu Sen strode ahead as if he did not care about Su Mo's Constellations Sword Formation.
"Kill!" Su Mo snapped. In a flash, 24 Spiritual Swords shone with dazzling brilliance and tremendous momentum as they rushed toward Wu Sen.
Swish!
Wu Sen finally moved. His figure instantly went downward.
As he went down, he was able to avoid getting surrounded by the Spiritual Swords, which was convenient for resistance.
Whoosh! Whoosh! Whoosh!
The 24 Natal Spiritual Swords moved in a mighty formation like a long river of sword Qi. Carrying a mysterious Constellations Force, they simultaneously rushed toward Wu Sen below.
"Break!" Wu Sen shouted loudly while repeatedly waving his claws. In an instant, the claw shadow filled the sky, severely crushing the 24 Spiritual Swords.
The claw shadow and the 24 Natal Spiritual Swords collided against each other.
Boom! Boom! Boom!
Explosions rang out in rapid succession. A Spiritual Sword flew out with each explosion.
Swoosh! Swoosh! Swoosh!
With claw shadows over the place, space disintegrated. The 24 Natal Spiritual Swords flew out in various directions.
"Su Mo, now your time is up!"
After dispersing the Natal Spiritual Swords, Wu Sen flashed across the void and instantly drew close to Su Mo.
He fiercely struck out with his claws and suddenly a huge claw shadow hit Su Mo's head.
"So powerful?"
Su Mo's face had a severe expression. Even with the 24 Constellations Sword Formation, he could not defeat Wu Sen.
Seeing Wu Sen's rapidly approaching claw shadow, he immediately withdrew.
Meanwhile, he extracted 40% of his essence, qi, and spirit by using the Three Secret Techniques.
If he did not use the Three Secret Techniques, he would be unable to defeat the other person, so he did not hesitate to pay the price.
Swish!
Su Mo moved backward rapidly but his aura increased wildly.
His aura had increased by several levels in half a breath. The raging aura broke through the sky.
The Three Secret Techniques was one of the most powerful secret skills, and it was rare in the world.
However, Su Mo found that as his cultivation improved, the increase afforded by the Three Secret Techniques had reduced a lot.
For example, while in the True Darkness Realm, Su Mo took 40% of his essence, qi, and spirit in order to quadruple his strength.
Afterward, every time he used the Three Secret Techniques, the increase was slightly lower.
Now, he that was at the Lv 4 Martial Royal Realm. If he drew 40% of his essence, qi, and spirit, it would only triple his strength.
Su Mo did not understand it but he did not bother to figure it out.
"Crush!"
As his strength greatly increased, Su Mo immediately stopped retreating. He brandished his sword to cut the approaching claw shadow.
Whoosh!
The brilliant sword radiance flew up to the sky and left a beautiful arc. With a boundless force, it instantly sliced at the claw shadow.
Chi!
The sword radiance was incomparably sharp, invincible, and mighty. It tore the claw shadow and cut through it.
"What?"
Seeing this, Wu Sen changed his face. Surprisingly, Su Mo had shattered such a powerful strike with a wave of his hands.
"Secret skill!" Wu Sen immediately perceived that Su Mo had greatly increased his strength by using some kind of secret skill.
"Kill!"
With a howl, Su Mo charged at Wu Shan like lightning.
The Emperor Sword shone with boundless brilliance. As he waved it heavily, earthshaking sword Qi, like a three-colored rainbow, went across heaven and earth and chopped toward Wu Sen severely.
A great sword power surged toward the open sky. Even if the sword was more than 30,000 meters from the ground, a huge sword mark instantly appeared on the ground.
Wu Sen withstood such pressure as he confronted the sword Qi.
"Kill!"
A deep voice came from Wu Sen's throat. He swiftly reached out his sharp wolf claws.
Radiating black light, the claws looked sharper and had more terrifying power.
Boom!
Shaking sword Qi collided so violently with the sharp claws that the surrounding area within a radius of 500 kilometers was obliterated.
Rolling blast wave swept out in all directions. The broken Emperor Xuan Mountain Range was destroyed and turned into a big crater more than 500 kilometers wide.
Pfft!
Wu Sen spat out a mouthful of blood. The Qi strength disappeared and vanished into nothing.
Whoosh!
With a harsh blast, Wu Sen flew backward like an arrow.
He stopped after flying backward for 500 kilometers. He tasted something sweet in his throat and spat out another mouthful of blood.
"Damn!" Wu Sen's eyes were full of killing desire. He had completely exerted the power of the Fighting Soul with the Human and Soul Combination, but he still could not defeat Su Mo.
After getting repeatedly wounded by Su Mo, his killing desire was almost-solid.
"A Martial Emperor Realm expert is just so-so."
Su Mo disdainfully spoke as he stepped onto the Natal Spiritual Sword and chased after Wu Sen at high speed.
"How dare you use a secret skill and still call yourself brave?" Wu Sen shouted angrily. His aura began to soar. His body swelled again. The black hairs became denser and the sharp claws grew faster and became longer and sharper.
Both of them used secret skills. Like fire beacons, their auras were soul-stirring.
The mood of the spectators kept fluctuating as if tossed around by a rough sea.
This was a peak battle. The battle situation changed quickly, and it kept changing.
People no longer believed that Su Mo was doomed to lose.
Based on the current combat situation, either of them could win. Anyone who was at a disadvantage might turn the tables anytime.
Therefore, the ultimate winner would depend on their hidden cards.
Right now, aside from the grim-faced Yin Zong, there was another person with an ugly expression in the Netherworld Devil Sect camp一it was Huangfu Qing.
Huangfu Qing's face was as dark as the bottom of a pan. He knew that the secret skill that Su Mo used was the Three Secret Techniques that he had imparted.
