I cultivate the Chaos Technique

As Zhang Yifan and the members of the Lingyun Sword Sect stepped into the teleportation portal, the scene before them instantly changed. The third level of the Heavenly Annihilation Tower felt particularly oppressive and eerie, as if they had stepped into another world. All around was a crimson rocky area, with magma gushing from the ground, and the air thick with heat, as if everything was about to be consumed. The sky was shrouded in thick gray clouds, with dark red flames flickering within them, making the entire space a terrifying inferno.

"Is this...purgatory?" Lin Qingzhu looked at the scene before her and couldn't help but whisper, her voice filled with suppressed emotions.

Zhang Yifan raised his head, his gaze fixed on the blood-red sky, and he thought to himself, "It seems that the test on the third level is related to fire, and the harshness of the environment is far greater than that of the first two levels."

Ling Yunfeng walked at the front, his feet treading on the scorching rocks, his eyes always on alert. He soon noticed something wriggling in the lava pool ahead.

"Everyone be careful, there's something ahead!" Ling Yunfeng warned in a low voice, gripping his longsword tightly, ready to face any unknown threat at any moment.

As Ling Yunfeng finished speaking, a deep roar suddenly erupted from the lava pool. Immediately afterward, a blazing pillar of fire shot into the sky, and from the flames slowly emerged a colossal figure—a behemoth formed from fire and rock. Its body seemed to be constructed of molten lava, its eyes burning with scarlet flames, like a demon resurrected from hell, carrying the power to destroy everything.

"Lava Beast!" Lin Qingzhu exclaimed, her expression changing slightly. The Lava Beast is an extremely powerful fire-attribute demon beast that lives in extremely high-temperature environments. Its body is composed of rock and flame, making it impervious to ordinary physical attacks. Worse still, this demon beast also possesses powerful fire magic, allowing it to continuously summon flames to attack its enemies during battle.

Zhang Yifan's expression turned serious. He quickly retreated, putting distance between himself and Lin Qingzhu: "Ordinary attacks cannot cause effective damage to it. We must find a way to exploit its weakness."

“That’s right, we can’t fight it head-on!” Ling Yunfeng’s expression was stern as he quickly scanned the lava beast’s body, trying to find its weakness.

The lava beast let out an angry roar, raised its massive rocky claws, and slammed them down onto the ground. Instantly, the entire earth trembled violently, and scorching magma surged from the ground, splashing everywhere and forming walls of fire that forced Zhang Yifan and the others to retreat repeatedly.

"These flames are extremely hot, we must avoid them!" Lin Qingzhu hurriedly dodged, but even so, she could still feel the scorching flames burning her skin.

Zhang Yifan swiftly swung his longsword, releasing a burst of sword energy in an attempt to cut through the wall of fire. However, the sword energy was instantly incinerated upon contact with the flames, unable to budge the scorching wall of fire.

"The wall of fire cannot be broken by the sword energy! Its power is too strong!" Zhang Yifan thought anxiously.

At the same time, Ling Yunfeng kept his eyes fixed on the lava beast's movements. Suddenly, a glint of inspiration flashed in his eyes: "Its core is in that red crystal on its chest! That's its Achilles' heel!"

"The core?" Zhang Yifan looked in the direction Ling Yunfeng pointed and sure enough, there was a crystal that was faintly shimmering with red light on the chest of the lava beast. The rocks around the crystal seemed to be more fragile, as if it were the source of its power.

"We must attack its core! Only in this way can we defeat it!" Ling Yunfeng decisively gave the order, and with a flash, he quickly rushed towards the lava beast.

Zhang Yifan followed closely behind, his longsword gleaming with a sharp light. He knew there was no time to hesitate; the lava beast's power was overwhelming, and if they couldn't strike its core in time, destruction would be their only fate.

The lava beast seemed to sense their intentions, letting out an angry roar as its massive claws swung down, unleashing scorching flames that erupted around its body, forming burning barriers in an attempt to block their attack.

Zhang Yifan swiftly dodged, avoiding the attack of the flame barrier. At the same time, he concentrated his sword energy to its maximum and slashed down at the core of the lava beast's chest. The sword light was like a rainbow, heading straight for the red crystal. However, just as the sword energy was about to touch the crystal, a powerful burst of fire energy erupted from the lava beast's body, directly shattering the sword energy.

"It's no use, its defense is too strong!" Zhang Yifan frowned, feeling anxious.

“We must find a weakness, otherwise we won’t be able to hit its core.” A calm, thoughtful glint flashed in Ling Yunfeng’s eyes. “Although the Lava Beast is powerful, each burst of flame consumes a large amount of spiritual energy. We just need to wait for the moment its spiritual energy weakens, and we will find an opportunity!”

Zhang Yifan nodded, realizing they couldn't launch a direct attack and had to wait for an opportunity. He and Ling Yunfeng worked together, maintaining their distance from the lava beast and searching for the moment when its spiritual energy was exhausted.

The lava beast swung its claws repeatedly, and scorching flames surged from the ground, making the surrounding air seem to ignite. However, as time passed, Zhang Yifan gradually noticed that the lava beast's movements became slower, and the bursts of flame were no longer as intense.

"The opportunity has come!" A sharp glint flashed in Ling Yunfeng's eyes. He quickly moved to the side of the lava beast, raised his longsword high, and gathered spiritual power on the blade, forming a dazzling sword light.

"Attack with all your might!" Zhang Yifan cooperated without hesitation, and his sword energy erupted in that instant, heading straight for the core of the lava beast.

The lava beast let out a final roar, attempting to use its last fiery barrier to block their attack. However, its spiritual power was clearly insufficient to sustain it, and the fiery barrier shattered instantly. Zhang Yifan and Ling Yunfeng's sword energy simultaneously struck the lava beast's core, and the massive red crystal shattered under the intense impact of the spiritual power.

As the crystal shattered, the lava beast's body rapidly collapsed, and the scorching rocks and flames instantly turned to ashes, dissipating into the air. The entire space returned to calm, the intense heat gradually subsided, and the lava pool slowly cooled, transforming into a tranquil red stone ground.

"We did it!" A joyful smile finally appeared on Lin Qingzhu's face.

Zhang Yifan let out a long breath, feeling the tension in his body instantly relax. The lava beast's strength far exceeded their expectations, but they ultimately defeated it through teamwork and patience.

"This test will assess our composure and judgment when facing a formidable enemy." Ling Yunfeng walked to Zhang Yifan's side, his eyes filled with satisfaction. "You all performed very well."

Zhang Yifan smiled slightly, about to speak, when suddenly, the ground around them began to tremble again. A deep voice echoed in the air, as if from the heavens:

"The Trial of Purgatory is over; the challenger has passed the third level."

As soon as they finished speaking, a familiar light appeared before them—a portal leading to the fourth level of the Heavenly Tower.

"Looks like we've passed another hurdle," Zhang Yifan said softly, his heart filled with mixed emotions. Each level of the test was more difficult than the last, and he didn't know what awaited them next.

"Let's go, let's continue forward," Ling Yunfeng said steadily, leading everyone back into the teleportation portal.

The trials on the fourth level of the Heavenly Tower are already waiting for them.
