"Good!" Liou Yuan responded in a deep voice, immediately activating the Treading Flowing Waves technique, heading swiftly toward the direction where he had set up the Refined Gold Breaking Mountain Array.

Meanwhile, Tuoba Xin remained motionless in place.

He had just handed Liou Yuan a Jade Scroll of a Thousand-Mile Ear, a high-quality artifact allowing the two to communicate instantly within the canyon.

He was waiting for Liou Yuan’s signal to begin the attack.

"Mr. Liou’s expertise in array formations is quite impressive, being able to set up an array that can trap a Half-Step Foundation Establishment cultivator."

Tuoba Xin stroked his chin, recalling Liou Yuan’s confident expression when he mentioned being able to block that Foundation Establishment Star Erosion.

"Moreover, with a pair of Mutated Spiritual Eyes, among this batch of disciples with Five-Star Star Acupoints, Mr. Liou is truly the most outstanding."

Before the Refined Gold Breaking Mountain Array, after Liou Yuan returned, he first used the surrounding mud and sand to crudely cover the traces of the array, then placed several stones on the front, only feeling satisfied when the place looked indistinguishable from the environment. He nodded with satisfaction, thinking to himself, "That Star Erosion has been residing in the Erosion Land without ever encountering an array. Without any defense in mind, it’s easy to fall into a trap."

After completing all this, Liou Yuan took out the Thousand-Mile Ear given to him by Tuoba Xin at parting and communicated, "Mr. Tuoba, I am ready."

Without waiting for Tuoba Xin’s response, Liou Yuan put the Thousand-Mile Ear into his pouch and activated the Night Concealing Mask on his face.

Buzz~

With a shimmer, Liou Yuan’s figure quietly merged into the darkness at the bottom of the canyon.

"I only need to control the array, no need for direct confrontation, so hiding in the dark is the most prudent," thought Liou Yuan as he started climbing the rock wall to the side.

Until he reached a protrusion on the rock wall, over a hundred feet above the ground.

From this position, Liou Yuan could clearly see the two arrays and the environment at the bottom of the canyon.

"This is it, just waiting for Tuoba Xin to lure that Purifying Dark Demon over," Liou Yuan surveyed his surroundings, grinning.

He hadn’t expected to be able to enlist Tuoba Xin’s help so smoothly.

Having such a powerful ally, he felt confident about killing the Purifying Dark Demon this time, firmly believing, "As soon as that demon enters the array, there’s a sixty to seventy percent chance of killing it."

On the other side, after receiving Liou Yuan’s transmission through the Thousand-Mile Ear, Tuoba Xin smiled slightly.

Without any delay, he summoned the Wind of Spirit and rushed towards the end of the canyon where the Purifying Dark Demon was located.

This time, he did not hide his tracks, spiritual power agitating around him, creating a fierce gale in the canyon.

Soon, Liou Yuan, lurking above the Refined Gold Breaking Mountain Array, heard a deafening, fierce sound emerging from the depths of the canyon.

Moo!

The sound was like the grating noise of two rough stones rubbing together, extremely sharp.

The sound traveled from the depths of the canyon, shaking loose sand from both sides before reaching Liou Yuan’s ears, giving him goosebumps.

"It’s starting!" Liou Yuan held his breath, opening his Evil Eyes to gaze in the direction of the Purifying Dark Demon within the canyon.

After the sound, a slight tremor emanated from the canyon’s interior.

The vibrations traveled through the rock walls on both sides of the canyon, reaching Liou Yuan, who was clinging to the cliff.

He could clearly feel the rock wall beneath his feet trembling.

In addition to the violent shaking of the rock wall,

a fierce and powerful gust surged through the canyon, lifting stones and sand into the air.

Suddenly, the central canyon was filled with flying sand and pebbles, making an already dim environment even harder to see.

The tremor in the canyon must have been caused by the Purifying Dark Demon.

So, it was obvious that the sudden gale within the canyon was created by Tuoba Xin.

Liou Yuan squinted in the gale, feeling the grit hitting the Night Concealing Mask on his face, thinking, "Tuoba Xin indeed has a Wind Acupoint!"

In the Cultivation Realm, there are many cultivators with Star Acupoints, mostly categorized under the Great Five Elements: Metal, Wood, Water, Fire, and Earth.

Each of the Great Five Elements has its own derivative Star Acupoint categories.

For example, Liou Zhen’s Ice Acupoint and Liou Tao’s Fog Acupoint are derivatives categorized under Water.

And the Wind Acupoint falls under Wood.

In the Eight Trigrams, Xun represents Wind, stands in the East, and belongs to Wood.

Similarly, the Thunder Acupoint is also akin to the Wind Acupoint.

Thunder is in the Zhen position, also stands in the East, and belongs to Wood.

Representative figures include Zhao Feiyue.

In his previous life, Liou Yuan loved reading many novels, where many authors incorrectly categorized Thunder under Fire, which he always found amusing.

The reason Liou Yuan was so concerned about Tuoba Xin’s Star Acupoints Five Elements was due to a realization.

"The highest transmission of Five Extremes Mountain, a Grade B Top-grade Foundation Establishment Skill, seems to be a Wood Acupoint Skill."

"Tuoba Xin really is blessed by destiny; if there are no mishaps, he will likely be given that Grade B Top-grade Foundation Establishment Skill by the Sect Leader to practice."

As a rare possessor of a Six-Star Star Acupoint in Five Extremes Mountain’s hundreds of years, if Xuanyi, the Sect Leader, is far-sighted enough, he would not hesitate to grant that Grade B Top-grade Foundation Establishment Skill.

Remembering this, Liou Yuan felt a pang of envy.

"Grade B Foundation Establishment Skill, while I strive desperately to enter the top three to acquire a Grade C Foundation Establishment Skill."

"Tuoba Xin just effortlessly attains the highest-level skill in Five Extremes Mountain."

Fortunately, Tuoba Xin is just an exception; not all geniuses in Five Extremes Mountain enjoy treatment akin to his, which slightly consoled Liou Yuan.

Liou Yuan’s thoughts wandered.
