Eight days later, outside the Valley of Absolute Yin. "We won't enter the Valley of Absolute Yin today.

Everyone rest well; we'll step inside first thing tomorrow morning." Zhua Qi stopped outside the valley, his expression grim. "Once we enter, the Nine-Headed Celestial Serpent will immediately detect us, and a great battle will be unavoidable." "Mm." Chi Xiao took out the treasure map again, beckoning Zhua Qi and Xia Xinyan over.

"On this last night, let's examine the map again. It would be best if we could pinpoint the exact location of the Heavenly Gate before we enter the Valley of Absolute Yin." Zhua Qi and Xia Xinyan gathered around, both frowning as they looked down at the map together.

Shi Yan, as usual, found a secluded spot and sat down, maintaining a distance from Zhua Qi and Chi Xiao, continuing his silent, arduous cultivation of the Profound Yin Art. For these eight days, Chi Xiao found excuses every evening to make the group stop and rest, all with the intention of giving Zuo Shi ample time to cultivate the Black Tortoise True Gang.

Shi Yan wasn't idle either. Whenever the others stopped, he knowingly found a place to quietly practice the Profound Yin Art, guarded by Han Feng and Ku Long.

After eight days of cultivation, Shi Yan had amassed a significant amount of Yin energy in the three acupoints in his chest: Tianque, Shenque, and Yindu. He spent his days meticulously using his consciousness to control this Yin energy, dividing it into wisps that revolved around the three points.

As the Yin energy increased, the speed of the circulating Yin energy at these three points gradually quickened, on the verge of truly forming Yin Vortices. Taking a deep breath, steadying his spirit, Shi Yan focused all his attention on controlling the Yin energy.

Wisp after wisp of Yin energy, like slender grey threads, slowly coiled around the three acupoints in his chest. As his thoughts shifted, the grey, thread-like Yin energy rapidly circled.

Every time this happened, Shi Yan could clearly sense the surrounding ambient Yin energy of the heavens and earth being drawn towards his body, quietly converging on him. Having practiced the Profound Yin Art for eight days, Shi Yan was gradually gaining some insight into the nature of Yin energy.

After circling in his chest for several days, the Yin energy seemed to be subtly altering his physical form... Now that he was outside the Valley of Absolute Yin, although the Yin energy of the heavens and earth was even denser, having cultivated the Profound Yin Art for eight days, he did not find it difficult to adapt.

On the contrary, the closer he got to the Valley of Absolute Yin, the more proficient he felt in practicing the Profound Yin Art; even inhaling the Yin energy gave him a sense of revitalization. Han Feng and Ku Long had no idea what martial art Shi Yan was practicing.

They stood guard faithfully by his side, not daring to let their guard down in the slightest. Time flowed quietly by.

Suddenly, Zuo Shi, who was being watched by Wu Yunlian and Chu Ping, jumped up with sudden joy. A strange glow flickered across her body as she exclaimed, "Ha!

I've reached the third heaven of the Human Position!" Chi Xiao, who had been poring over the treasure map, was overjoyed. He rushed over immediately, grasping Zuo Shi's small hand to check her pulse, his aged face filled with relief.

"You little brat, truly..." From the reaction of the vital essence in Zuo Shi's body, Chi Xiao could tell she had indeed entered the realm of the third heaven of the Human Position. He was both shocked and delighted.

Zuo Shi had cultivated the Black Tortoise True Gang for eight days, and although she hadn't fully refined it, she had suddenly broken through to the third heaven of the Human Position. Such talent left Chi Xiao at a loss for words.

Other than genius, Chi Xiao could find no other term to describe Zuo Shi's innate talent. Since entering Tianyun City from the Cloud Mist Mountain Range, Zuo Shi hadn't seriously cultivated for a single day, spending all her time wandering around.

Yet, even so, she managed to reach the third heaven of the Human Position in such a short time. This greatly exceeded Chi Xiao's expectations.

"Mr. Chi Xiao, you have taken on a fine disciple." Xia Xinyan's beautiful eyes also flashed with a hint of surprise; she was secretly startled by Zuo Shi's astonishing talent.

"Heh heh, this girl certainly has amazing talent, just a bit too lazy," Chi Xiao replied, in an excellent mood. He patted Zuo Shi's shoulder with a smile.

"Keep working hard! Strive to fully comprehend the Black Tortoise True Gang as soon as possible.

Girl, if you could focus all your mind on breakthroughs in the martial path, your realm would be at least one level higher than it is now!" With that, Chi Xiao walked back over to Xia Xinyan and Zhua Qi, bowing his head with a faint smile. "Forget about that girl for now; let's get back to the map." ...

Two more hours passed. Shi Yan sat there silently.

His body suddenly shuddered, followed by a slight tremor. At his chest, the continuously gathering and coiling Yin energy began to spin faster and faster.

Looking inward, he found that at the Tianque, Shenque, and Yindu acupoints, the wisp-like grey Yin threads began to slowly lengthen, revolving rapidly around the three points. The Yin energy absorbed by his body suddenly poured madly into those three acupoints.

Large amounts of Yin energy were injected, immediately refined and decomposed, transforming into more grey threads. More and more grey threads gathered in the small eddies at his three acupoints, causing the vortexes to spin faster and faster...

After an unknown amount of time, a chilling aura suddenly radiated from the three vortexes, causing Shi Yan to grow cold all over and involuntarily shiver. More Yin energy from all directions converged, flooding into his pores and injecting into the center of the three vortices.

The speed of the vortex rotation increased further! Looking inward, Shi Yan was horrified to see that the three spinning vortexes had blurred into an afterimage.

Within the three acupoints, a powerful suction force suddenly erupted from the vortexes. It was complete!

The emergence of a strong suction force within the vortexes meant the Yin Vortices had officially formed! The ability of the Yin Vortices to devour the Yin energy of the world was triggered instantly!

Suddenly, the pervasive Yin energy swirling across the Absolute Yin Plain seemed to have found an outlet, gathering frantically from all corners, surging towards Shi Yan's location like a bursting river. About ten meters above Shi Yan's head, three strange vortexes, each the size of a human head, gradually formed.

These vortexes bore a striking resemblance to the Yin Vortices inside Shi Yan's body. Clearly influenced by the Yin Vortices in his chest, they rotated along with the spinning of his internal vortices, generating an immense sucking force that drew in even more Yin energy from the heavens and earth.

The incredibly dense Yin energy surged into the three head-sized vortexes above Shi Yan's head, causing their volume to increase rapidly! In just ten minutes, the vortexes grew to the size of washbasins, continuing to devour the Yin energy gathering from all directions with ferocious speed.

Chi Xiao, Zhua Qi, and Xia Xinyan had long stopped discussing the treasure map. They all stood up, staring with astonishment at the anomaly above Shi Yan's head.

The volume of the three vortexes continued to swell! One hour later, the three vortexes above Shi Yan's head were as massive as tornadoes, shooting skyward like three columns of wolf smoke, appearing incredibly terrifying.

The vortexes spun wildly, as if attempting to devour every single bit of Yin energy in the entire Absolute Yin Plain in one go! Shi Yan sat there motionless, his expression grave and solemn, seemingly unaware of the abnormality above him, as he continued to control the three internal Yin Vortices.

He distinctly felt the rotational speed of the three Yin Vortices in his chest increase several times over! Even his thoughts could no longer keep pace with the speed of their rotation.

Han Feng and Ku Long watched the bizarre phenomenon above Shi Yan's head with looks of utter horror, unsure of what to do. The grey Yin energy that had shrouded the Absolute Yin Plain for countless years isolated it from the outside world, preventing even the light of the sun, moon, and stars from penetrating.

But today, all the Yin energy covering the entire plain seemed to have gone mad, pouring desperately into the gigantic vortexes above Shi Yan's head. At some point, the three vortexes above Shi Yan had grown as tall as three mountains, threaded with traces of strange electric light, resembling three giant mouths ready to swallow the heavens and earth, intent on devouring all the Yin energy in the world.

"This, this looks like..." A towering man beside Xia Xinyan suddenly cried out, as if remembering something. "What?" Xia Xinyan turned towards him, her eyes gleaming with a strange light.

Under Xia Xinyan's gaze, the giant hesitated for a moment, then quietly started moving to the side. Zhua Qi and Chi Xiao also experienced drastic changes in expression, staring in disbelief at the phenomenon above Shi Yan.

Hearing that the giant seemed to have made a discovery, they quickly looked over. Xia Xinyan frowned and, along with the giant, distanced herself from Zhua Qi and Chi Xiao, listening to the giant's anxious explanation.

"Are you sure?" A sentence faintly carried from Xia Xinyan's direction. The giant nodded repeatedly, appearing somewhat anxious, staring at Shi Yan with fear.

"Absolutely no mistake, it must be that..." Xia Xinyan's expression shifted dramatically, and she nodded slowly. Then, she suddenly turned to Chi Xiao and Zhua Qi.

"Prepare for battle. The Nine-Headed Celestial Serpent should be coming out of the Valley of Absolute Yin soon.

Since it relies on the Yin energy of heaven and earth for three of its heads to cultivate, it will surely attack at all costs. We don't need to go into the Valley of Absolute Yin." "Miss Xia, my young master, what...

what exactly is happening to him?" Ku Long stepped forward, flustered and panicked. "Ask him yourself when he wakes up," Xia Xinyan replied, her brow deeply furrowed, her eyes full of a strange color.

"But you can rest assured, the abnormality emanating from his body is not harmful to him. On the contrary, this is a huge opportunity.

If no one disturbs him, he alone can swallow all the Yin energy covering the entire Absolute Yin Plain!" "Ah!" Chi Xiao, Zhua Qi, Wu Yunlian, Zuo Shi, and the others all cried out, their faces filled with disbelief. "This kind of cultivation technique is just that domineering; I don't know how it fell into his hands," Xia Xinyan's expression was immensely complex.

"The Nine-Headed Celestial Serpent will be here soon. It will never allow anyone to devour the Yin energy here.

We might not have to wait until tomorrow; we may have to face its wrath any moment now!" "Roar! Roar!

Roar!" A series of frantic roars suddenly erupted from the Valley of Absolute Yin, roars filled with overwhelming fury. "Boom boom!

Boom boom!" A ground-shaking roar suddenly came from the direction of the Valley of Absolute Yin. The group trembled slightly, feeling the earth shake beneath them, sensing a colossal being rapidly approaching.

"It's coming!" Zhua Qi shrieked. ...
