I cultivate the Chaos Technique

The stone gate of the Heavenly Annihilation Tower slowly opened, and a chilling aura surged out from within, seemingly emanating from the depths of the earth, carrying an extremely ominous presence. All the cultivators' gazes were fixed on the deep, dark passageway, their hearts filled with a mixture of anticipation and fear of the unknown.

Just then, a deep voice came from inside the tower, a voice with a mechanical indifference and ruthlessness that echoed in the ears of every cultivator.

"The Tower of Heavenly Annihilation was built in ancient times to test cultivators. The tower has nine levels, each with different trials. Those who pass each level will receive generous rewards. However, each level is also full of life-or-death dangers. Those who fail to pass the tower will be buried here forever, their souls scattered."

The voice was deep and sinister, as if from the abyss, as if some ancient will was governing everything. The cultivators outside the tower became even more vigilant; the danger inside the tower was clearly beyond their imagination. But at the same time, the words "generous reward" excited many of them.

“The Nine-Story Pagoda is fraught with danger on every level, but the rewards are absolutely substantial.” Ling Yunfeng stood beside Zhang Yifan, his gaze stern, and said in a low voice, “We must go all out to conquer each level.”

Zhang Yifan nodded, already considering his next move. The trials within the Heavenly Annihilation Tower were clearly more than just simple battles; the tower was riddled with traps and heavily guarded, each level potentially a fatal challenge.

Just then, the voice continued, "The rules for conquering the tower are as follows: Each floor has a time limit, and those who exceed the time limit will be eliminated; each floor you pass will grant you a corresponding reward, which can enhance your strength or heal your injuries. However, the restrictions within the tower are merciless, and any violator will be immediately expelled from the tower and never allowed to re-enter."

As the sound faded, a deep tremor emanated from within the tower, as if some enormous mechanism had been activated. A faint light flickered in the darkness within the tower, seemingly awaiting the arrival of the cultivators.

"A time limit, and a generous reward?" Zhang Yifan's heart tightened. This trial not only required cultivators to have strong combat abilities, but also demanded that they pass the test within a specified time. The slightest mistake could mean permanent demise.

"It seems this trial is definitely not simple," Lin Qingzhu whispered beside him, a hint of worry in her eyes.

"We must remain calm and not act rashly," Ling Yunfeng said in a deep voice. Although he appeared extremely composed, Zhang Yifan could sense that Ling Yunfeng was also under immense pressure. The appearance of the Heavenly Annihilation Tower was not only an opportunity, but also a tremendous test for all cultivators in Qingzhou.

At that moment, General Fei Hong of the Tianyuan Dynasty took the lead. He led more than thirty cultivators, striding towards the tower gate with resolute expressions. The cultivators of the Tianyuan Dynasty followed him without hesitation, clearly having made thorough preparations. General Fei Hong glanced back at the cultivators from the other sects and nodded slightly, as if indicating that they could follow.

"Let's go too," Ling Yunfeng said firmly, looking at Zhang Yifan and his fellow disciples.

Zhang Yifan and Lin Qingzhu exchanged a glance, nodded, and followed closely behind. They entered the entrance to the Heavenly Tower, and the stone door behind them creaked and slowly closed, completely shutting out the outside light.

The tower was pitch black, filled with dense spiritual energy fluctuations, as if every corner was fraught with danger. Zhang Yifan gripped his sword warily, cautiously observing his surroundings. He knew that the trials within the tower could begin at any moment.

Suddenly, a soft humming sound came from inside the tower. As the humming sound continued, beams of light suddenly lit up on the ground beneath their feet, quickly converging into a massive teleportation array. Before Zhang Yifan and the others could react, the array's light intensified, instantly enveloping them.

In a dizzying spin, the scene before Zhang Yifan suddenly changed, and he and the others from the Lingyun Sword Sect were teleported to a completely new space. This was the first level of the Heavenly Annihilation Tower.

The first level wasn't large, surrounded by tall stone walls covered in densely packed runes that emitted a faint glow, casting a dim and oppressive light over the space. A dangerous aura permeated the air, as if some powerful being was lurking in the shadows, watching them.

"Is this the first level of the Heavenly Tower?" Zhang Yifan frowned, his eyes fixed on his surroundings, secretly on guard.

Just then, a cold voice rang out again in the air: "First Trial - Undead Invasion. Cultivators, defeat all undead within the allotted time. Those who exceed the time limit will be annihilated."

As the sound faded, the surrounding stone walls suddenly began to tremble, and a low, hissing roar came from all directions. Immediately afterward, an extremely eerie aura filled the air, and countless black cracks appeared on the ground, from which streams of black mist surged forth. The black mist quickly condensed and took shape, transforming into undead warriors.

These undead warriors wore tattered armor, wielded rusty swords, and their eyes gleamed with a cold, eerie light. They seemed to have once been powerful cultivators of a bygone era, now reduced to guardians of the Heavenly Tower, forever wandering in this world of death.

"Undead?!" Lin Qingzhu exclaimed, gripping her longsword tightly, ready to fight.

"Kill them with all your might! Don't let them get close!" Ling Yunfeng calmly issued the order, wielding his longsword. Spiritual power erupted, and the sword light, like a rainbow, rushed straight towards the foremost undead.

Without hesitation, Zhang Yifan charged forward, his sword energy swiftly slashing towards the undead. The sword light collided with the undead's bodies, producing a loud "bang," and the undead's body was instantly cleaved in two. However, the undead that was cut in half did not disappear, but instead turned into a cloud of black mist, which instantly reformed.

"These undead seem unkillable?" Zhang Yifan frowned, a sense of foreboding creeping into his heart.

"They are souls resurrected by the power of the Heavenly Annihilation Tower. We must find their weakness to completely destroy them!" Ling Yunfeng said coldly. His sword energy once again slashed at the head of the undead. This time, the sword light directly hit the core of the undead. The undead instantly let out a shrill wail, and its body turned to ashes and disappeared completely.

Zhang Yifan immediately understood, and his longsword unleashed even stronger spiritual power, specifically targeting the core of the undead. In no time, he had slain several undead warriors, but the undead seemed endless, continuously pouring out from the cracks.

Meanwhile, the cultivators of the Tianyuan Dynasty were also engaged in fierce combat not far away. Their battle formations were extremely well-coordinated, and each cultivator displayed exceptional combat prowess, quickly eliminating the surrounding undead. General Fei Hong stood at the forefront of the group, wielding his greatsword, his sword energy sweeping across the battlefield, instantly annihilating a large number of undead.

"We need to hurry, this is only the first level," Ling Yunfeng said in a deep voice, a hint of anxiety in his eyes.

As time passed, the number of undead gradually increased, and the battle became increasingly fierce. The atmosphere within the tower also grew colder, as if some even more terrifying force awaited their arrival.

"We must get through this level as soon as possible!" Zhang Yifan gritted his teeth, his sword flashing brightly. He knew that time was running out.
