At this critical moment, a deafening tiger roar suddenly resounded, shaking the very air. "Roar!" Immediately, a strange light shone from Bai Zhiwen's body, and he instantly transformed into an immense white tiger. Like a moving mountain, he burst forth from the deep pool of chaotic spiritual water. It turned out that he had successfully ascended to the physique of a peerless demon king, his strength instantly increasing dramatically.

As soon as Bai Zhiwen appeared, he raised his steel-hard tiger claws and slashed at Huang Gangchen. Huang Gangchen's face changed drastically, and without a second thought, he quickly used his agility to dodge. With a loud "boom," the giant claws slammed down onto the ground, sending dust flying and creating a massive crater. The Tai Chi diagram shifted to the side, whizzing past Yu Kai's side. The powerful airflow cut through like a sharp blade, sending Yu Kai flying.

Before Bai Zhiwen could even move forward to check on Yu Kai's injuries, the Tai Chi diagram roared toward him again. Undeterred, he raised his claws once more and slapped them with all his might. "Boom!" A powerful recoil surged like a surging tide, leaving him no time to dodge. His massive body was directly struck by the Tai Chi diagram, slamming into the earth like a falling meteor with a deafening roar. The entire Lingyun Valley shook violently, as if on the verge of collapse.

"Roar!" Bai Zhiwen roared angrily, turned over and stood up like a bloody god of war, shook off the dirt on his body, and pounced on Huang Gangchen again, with a bloodthirsty gleam in his eyes, vowing to tear Huang Gangchen to pieces with his sharp claws.

Seeing Bai Zhiwen's tough skin and flesh, being hit time and time again yet still stubbornly charging forward, Huang Gangchen couldn't help but feel a little frightened. But he remained tough, snorting coldly, "You evil creature, you're really courting death!" Then, he once again manipulated the Tai Chi diagram, sweeping it towards the white tiger like autumn wind sweeping away fallen leaves.

This mysterious Tai Chi diagram was truly terrifying. Each time, it accurately blocked Bai Zhiwen's attacks, even returning the force, sending him flying again and again. As time passed, even Bai Zhiwen, with his formidable physique, became battered and bruised, his body covered in horrific wounds and dripping with blood. But he remained resolute as steel, charging forward again and again, engaging Huang Gangchen in a desperate struggle.

Meanwhile, Yu Kai seized the opportunity to rapidly recover. He channeled his spiritual energy, constantly invoking the Law of Evolution and engaging in in-depth deductions with the Law of Chance. Since the Taiqing Xuande Hall contained a supreme treasure like the Tai Chi Diagram, it stands to reason that the Wahuang Lingyun Valley, also founded by a sage, would not also contain similar treasures. Now, the entire Lingyun Valley was ravaged by their fierce battle, yet why was the mysterious treasure still missing? And where were the legendary spiritual insights left by the sage? A sage wouldn't deceive future generations, would he?

"Nuwa has devoted so much effort to establishing this Lingyun Valley, intending to cultivate a peerless demon king. Naturally, she wouldn't let the treasure fall into the hands of humans. And Bai Zhiwen already possesses the physique of a demon king, so why hasn't this treasure been chosen for him?" Yu Kai fell into deep thought. "A peerless demon king might not be enough to change the fate of the demon race. Otherwise, Sun Wukong wouldn't have converted to Buddhism. So, to whom will Nuwa bestow this treasure? To truly change the fate of the demon race, a saint may be needed!" Yu Kai's eyes suddenly lit up, as if he had grasped a key clue. "A saint... do I need the potential to become a saint to obtain this treasure?"

With this thought in mind, Yu Kai secretly activated the Law of Chaos with all his might, and with an almost frantic frenzy, he launched a blanket search throughout Lingyun Valley. The Chaos Body was truly heaven-defying. If even a Chaos Body couldn't achieve Sagehood, what other physique could possibly qualify? However, Yu Kai searched every corner of Lingyun Valley, yet still found nothing. "What on earth is going on? Where is this treasure?" He grew increasingly anxious, as Bai Zhiwen, now completely exhausted, was struck once again by the Tai Chi diagram. Blood rained down, and he was sent flying.

As another fatal blow approached, the Tai Chi diagram whistled past like a deadly ghost, slashing directly at Bai Zhiwen, seemingly intent on taking his life. Yu Kai, terrified, was about to rush to his rescue, Yueling Sacred Sword in hand, when the Qilin Beastmaster, Ruiying, unleashed a deafening roar. A mountain-sized Qilin, radiating auspicious light, charged towards Huang Gangchen like a blazing star. The Qilin raised its arm, thick as a celestial pillar, high in the air and struck Huang Gangchen with a fierce blow.

At the same time, Shen Xingze also took off into the air and shouted loudly: "Brother, come here quickly to recover, let's go kill him!"

Yu Kai, overjoyed at their improved physical condition, no longer hesitated, transforming into a streak of light and dashing towards the soon-to-drain pool like lightning. With a "splash!" he sat down in the pool, rapidly refining the Chaos Spirit Water. As if summoned by some mysterious force, the Chaos Spirit Water surged toward Yu Kai like a joyful stream. Nourished by the Chaos Spirit Water, his injuries healed at a visible rate. His Chaos Body, under the influence of this Chaos Spirit Water, grew even stronger, his spiritual power rapidly recovering like a surging river.

Watching Yu Kai rapidly recover in the Chaos Spirit Water, Huang Gangchen felt a surge of anxiety. He was consumed with anxiety, desperate to escape the clutches and restraints of Shen Xingze and the others. However, after their physical upgrades, the two demons had both experienced a qualitative leap in strength, becoming immensely powerful. Although the Tai Chi diagram in his hands offered unparalleled defense, he gradually began to struggle against the combined attack of the three.

The trio's coordination grew increasingly seamless. Each time, Qilin Beast Master Ruiying, clad in sturdy golden armor, would brazenly attack the Tai Chi diagram, drawing Huang Gangchen's attention. Shen Xingze and White Tiger Demon King Bai Zhiwen would seize the opportunity and launch a furious, violent assault. As a result, Huang Gangchen's injuries steadily intensified under the trio's relentless assaults, suffering repeated blows. He knew that if he didn't escape today, he would truly perish in this Wahuang Spiritual Valley.

With this thought, Huang Gangchen steeled his resolve and unleashed his full strength. The Tai Chi diagram shone brightly, instantly growing several times larger. Like a gigantic Yin-Yang wheel, it swept towards Shen Xingze and the others with overwhelming force. Simultaneously, he transformed into a streak of light, taking advantage of the moment the three men dodged the Tai Chi diagram's attack and dashing desperately toward the distance.
