I'll make you the furnace and the cauldron, so you can refine Yin and Yang and prove the Great

The moment the teleportation array lit up beneath my feet, everything in my field of vision was stretched into countless blurry lines. Heaven and earth turned upside down, and even breathing became difficult.

When he regained his sense of grounding, he found himself standing on a platform in a mountain hollow hidden by dense forest. The concentration of spiritual energy in the air was much thinner than in Wanxian City, but there was a familiar, chilling lingering demonic aura, like a very thin mist covering the surrounding mountains and forests.

Several array flags, slightly blackened by spiritual energy, were planted around the platform, and the array patterns on the ground were mostly covered by a layer of dark gray moss, indicating that this teleportation array had not been used for a long time.

"This is a hidden spy of the Immortal Alliance on the Demon Sect's territory." Yin Yue stepped down from the edge of the array, her silver veil fluttering gently in the night breeze. "It is located at the junction of the three major sects of the Demon Sect. To the north is the territory of the Joyful Union Sect, to the west is the direction of the Heavenly Demon Sect, and to the east is the territory of the Yinming Sect. It is a no-man's-land, and no one will spend too much effort patrolling it."

Li Hanshan stepped down from the platform, his feet resting on the soft layer of fallen leaves. He slowly circulated his pure Yang energy through his meridians, confirming that the teleportation had not left any hidden injuries.

He surveyed the surrounding terrain. The valley was surrounded by mountains on three sides, with only a narrow exit facing south. The ridge was covered with a dense forest of ancient trees, completely obscuring the platform. From the outside, it was impossible to detect that there was a teleportation array here.

After the two emerged from the mountain valley, Yin Yue summoned the silver-white flying boat. Instead of flying directly north, the boat first glided westward along the treetops in a large arc, avoiding several areas along the way that faintly emitted spiritual energy fluctuations, before turning due north.

Li Hanshan stood at the ship's railing, gazing at the vast mountain range below, which stretched out in the night like the spine of a sleeping behemoth. These mountains were even more rugged and primitive than those of the Immortal Alliance. Occasionally, a few scattered lights could be seen in the valleys, the gathering places of small sects or rogue cultivators affiliated with the Demonic Sect. Although the concentration of spiritual energy in the air was not high, it carried a more untamed and primal aura.

"Has the Immortal Alliance built quite a few teleportation arrays on the Demon Sect's territory?" he asked.

Yin Yue stood at the bow of the ship, her silver-white veil billowing to her chin in the oncoming wind, her calm eyes gleaming with a cool light in the moonlight. She didn't turn around; her voice came from ahead: "Of course. The Immortal Alliance has deployed at least a dozen teleportation arrays around the three major sects of the Demonic Sect, scattered in various hidden locations. These arrays are larger than the one you just saw, and their range is much greater; some can even connect directly from the Immortal Alliance's southern defense line to the edge of the Demonic Sect's heartland."

Li Hanshan's brows twitched slightly: "Since there are so many teleportation arrays, why not just use them? It's much faster than flying boats."

Yin Yue shook her head: "Those teleportation arrays are too large and too far away. Once activated, they will generate extremely strong spatial fluctuations. These fluctuations are very noticeable in the Demonic Sect's detection arrays, and can be sensed by patrolling cultivators within a radius of thousands of miles. The Immortal Alliance's hidden teleportation arrays are usually only used in two situations: one is to send spies to infiltrate the Demonic Sect to carry out missions, and the other is for troop mobilization before a large-scale attack. Nobody touches them under normal circumstances."

She turned half her face to the side, her eyes gleaming with a faint silvery-gray light in the moonlight: "Moreover, most of these teleportation arrays are deployed in the outer areas of the three major sects of the Demonic Sect, making it impossible to build them inside the core territory. The Demonic Sect's patrol density in its core area far exceeds your imagination. There are detection networks underground, patrol lights in the air, and even the spiritual energy fluctuations deep within the earth's veins are monitored regularly. Although the Immortal Alliance has many spies planted within the Demonic Sect, it is almost impossible to build a teleportation array in the core area. Even if it were built, once discovered, not only would the array be destroyed, but the spies would also die, and the entire secret network would be severed."

Li Hanshan felt that there was one more thing she hadn't mentioned: there were too few array masters capable of building teleportation arrays, and the Immortal Alliance wouldn't risk letting them venture deep into the core area of ​​the Demon Sect.

If even one is lost, the loss would be enormous.

"Moreover, even if it were built within the core territory of the Demon Sect, it wouldn't be of much use," Yin Yue continued.

"Not very useful?" Li Hanshan asked, puzzled.

Yin Yue nodded slightly: "The protective formations of the three major sects of the Demonic Sect are too sturdy. The Dragon Spine Spiritual Vein of the Joyful Union Sect, the Heavenly Demon Blood Array of the Heavenly Demon Sect, and the Myriad Ghosts Soul-Locking Array of the Yinming Sect—each of these formations has been reinforced over thousands of years and is sufficient to withstand attacks at the Dao Integration level. Even if the Immortal Alliance's army breaks out from the teleportation array, as long as the other side activates its protective formations and holds firm, we simply cannot break through. Furthermore, the three sects of the Demonic Sect support each other; once one sect is attacked, reinforcements from the other sects will definitely arrive. Therefore, a simple teleportation raid is actually of limited use."

As she spoke, she turned around and looked at Li Hanshan's face: "That's why I need you to set up an array inside the Heavenly Demon Sect. When that happens, the Immortal Alliance's army will appear directly inside the Heavenly Demon Sect, and even if the other two sects come to its aid, it will be too late."

Li Hanshan suddenly realized a problem: "Since the Immortal Alliance can be discovered if they build a teleportation array on the Demon Sect's territory, wouldn't it be even more dangerous if I build one inside the Heavenly Demon Sect? Once discovered, I won't even be able to escape."

A faint smile appeared in Yin Yue's calm eyes. The smile seemed particularly gentle in the moonlight, like a crescent moon that had been hidden by clouds for too long and was finally revealing its outline.

She spoke, her voice as clear and crisp as ever, yet with an added layer of certainty: "Don't worry. With me here, we won't be discovered."

Li Hanshan looked at her face, which was mostly covered by a silver veil, and remained silent for a moment.

The flying boat continued its northward flight through the night. The terrain beneath its feet changed from rolling hills to steeper mountain ranges, and then from mountain ranges to deep valleys shrouded in dense spiritual mist.

The further north you go, the higher the concentration of demonic energy in the air becomes. Even the array patterns on the surface of the flying boat begin to show a very faint dark gray luster, which is the cold and yin components in the demonic energy continuously eroding the spiritual energy circulation paths at the edges of the array patterns.

Just as Li Hanshan was about to return to his cabin to rest, he suddenly sensed an extremely familiar aura rapidly approaching from behind the airship. That aura carried a strong Yin energy, like a shattered dark tide, drawing an almost invisible dark trajectory in the night sky, and was chasing after the airship at an extremely fast speed.

He turned his head and saw the dark trail slow down slightly as it approached the airship, then land precisely on the edge of the ship's side. When the light faded, a hunched figure was revealed, his gray-black robe fluttering in the night wind, his cloudy eyes turning slightly in the moonlight, like an old demon that had just emerged from the deep mountains.

It was Yin Lingyue. Her disguise was still that of a withered old woman, but the spiritual energy fluctuations around her at the Nascent Soul level could not be completely concealed, and a very faint dark ripple appeared in the array light of the flying boat.

She had been waiting for Li Hanshan north of the Immortal Alliance's defense line. After Li Hanshan left the Immortal Alliance, he used Yangwen to send Yin Lingyue to find him.

Between Yin and Yang patterns, they can already sense location across great distances. Li Hanshan can sense the location of all Yin pattern owners. As for reverse sensing, Li Hanshan needs to actively release location information.

It can also convey some simple information.

Yin Lingyue saw Li Hanshan and her face lit up with joy. She was about to speak.

Yin Yue had already walked over from the bow of the ship. Her gaze fell on Yin Lingyue's withered disguise, and a faint scrutiny appeared in her eyes beneath the silver veil. She tilted her head slightly, her tone still clear and cold: "Who is she?"

Li Hanshan turned to the side, his tone calm: "Don't worry, she's my woman."

Yin Yue's gaze lingered on Yin Lingyue's old woman appearance for a moment, her lips slightly parted beneath the silver veil, her voice clear and calm: "You want such an old woman?"

Yin Lingyue's eyes suddenly turned. A natural anger, born of being publicly offended, surfaced on her withered face.

She suddenly raised her right hand and formed a hand seal. Dark gray spiritual energy rapidly condensed in her palm, and her hunched figure quickly expanded, stretched, and reshaped like ashes scattered by the wind.

His withered skin regained its whiteness, his cloudy eyes turned into a clear dark purple, his hunched back straightened, and a slender and well-proportioned silhouette was revealed beneath his gray-black robe.

Yin Lingyue stood by the ship's railing, her long, dark purple hair fluttering in the night wind. Her face, now restored to its original appearance, carried a suppressed stubbornness. Her gaze fell on Yin Yue's face, and her tone was icy: "Who are you calling old?"

At this time, Yin Yue had not yet revealed her aura, otherwise Yin Ling Yue might not have dared to speak to Yin Yue like this.

Yin Yue's gaze lingered for a moment on the woman's face, now restored to its original state, and the corner of her mouth twitched slightly beneath the silver veil. She tilted her head, as if re-examining the female cultivator who had just transformed from an old woman into a young woman, and after a moment spoke: "That's more like it."

She turned around, her gaze passing over Yin Lingyue and landing on Li Hanshan: "We have important things to do, let's not waste time here."

Li Hanshan walked up to Yin Lingyue and embraced her delicate body: "You go on your way, don't delay my business."

Yin Yue guessed what Li Hanshan was planning to do, her gaze filled with disdain: "Why are you thinking of doing that kind of thing?"

"I'm trying to improve my cultivation," Li Hanshan tilted his head, his gaze falling on Yin Lingyue, his tone somewhat matter-of-fact. "You know I'm only one step away from the Void Refinement stage. My physical strength needs to catch up, and dual cultivation with Yin Lingyue will definitely help me. Why don't you help me?"

Upon hearing this, Yin Lingyue's beautiful eyes instantly showed deep surprise, followed by a hint of admiration.

Li Hanshan has only been in the Immortal Alliance for less than ten years, yet he has already reached the peak of the Nascent Soul stage!

She naturally didn't know that Li Hanshan had entered the Flowing Light Array.

Yin Yue's gaze lingered on Li Hanshan's face for a moment. Beneath the silver veil, a faint ripple stirred in her calm eyes, and an almost imperceptible blush rose at the base of her ears, spreading downwards and disappearing into the edge of her silver collar.

After she finished speaking, she turned around and said, "We still have a lot of time to travel, so you can make your own arrangements. There is an empty room in the cabin, so don't make too much noise."
