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

Yin Yue nodded slightly: "The Heavenly Demon Blood Array is integrated with the entire earth vein, taking advantage of the terrain. The orientation of those mountains is not natural, but was deliberately adjusted by the powerful figures of the Heavenly Demon Sect throughout the ages. Each ridge is a spiritual energy guide, continuously transmitting the spiritual energy from the depths of the earth vein to the core node of the array. The entire array has become completely integrated with this terrain. Unless this entire mountain range is flattened, it is impossible to find its weakness."

Li Hanshan remained silent for a moment, repeatedly simulating the dark red sky in his mind. If the teleportation array wasn't placed inside the Heavenly Demon Blood Array, even if it were placed outside the Heavenly Demon Sect's gate, the Immortal Alliance army wouldn't be able to breach this barrier in a short time. Furthermore, the Heavenly Demon Blood Array covered an area of ​​several thousand miles, with crisscrossing mountains and valleys, and complex and ever-changing spiritual energy flows within it; placing a teleportation array within it would indeed be difficult to detect.

Of course, this is on the premise that there is a hidden moon to conceal it; otherwise, it would be very difficult to arrange it like that.

He withdrew his divine sense and his gaze fell on Yin Yue's face: "How do you plan to get in?"

Yin Yue took out a completely black token from her sleeve. The token was about half the size of her palm, with an ancient character "圣" (Saint) engraved on its surface. Fine dark gold patterns flowed along its edges, giving it a cold, eerie luster in the demonic wind. She held the token in her hand and propelled the flying boat forward, heading towards the dark red blood array dome.

As the airship approached the edge of the blood array, a thick, dark golden beam of light shot out from the surface of the dome, precisely sweeping across the airship's hull, like an invisible giant ruler measuring the entire airship's size and spiritual energy fluctuations. Immediately afterward, a deep, resonant voice echoed from within the blood array: "Who goes there? Show your token!"

Yin Yue did not slow down; the flying boat continued towards the direction of the scanning beam. She stood at the bow, her silver veil fluttering in the demonic wind, her calm eyes surging with coldness.

The moment the airship passed the edge of the blood array, the scenery abruptly changed. The dark red sky overhead closed again, and the ground beneath their feet transformed into a valley covered by a dark golden light membrane. The stone walls on both sides of the valley were inscribed with dense, dark red array patterns, and dozens of patrolling disciples' escape lights converged from all directions, forming a semi-circular array to block the airship's path.

The leader, dressed in a dark red robe, had a stern face. His gaze swept across the hull of the flying boat and landed on the silver-white figure at the bow. His movements suddenly paused, and the sternness on his face instantly turned into respect.

"So it's Her Majesty the Holy Maiden." He clasped his hands in greeting, his voice a few decibels lower than before. "This subordinate was unaware of the Holy Maiden's return to the sect and failed to greet her from afar. Please forgive me."

Saintess? Li Hanshan stood at the cabin door, his gaze fixed on Yin Yue's silver-white figure.

She was actually the Holy Maiden of the Heavenly Demon Sect. She had infiltrated the Immortal Alliance for so many years, establishing herself within its core with her late-stage Void Refinement cultivation, while simultaneously holding the title of Holy Maiden within the Demon Sect. This double-edged pawn carried far greater weight than he had previously anticipated.

Yin Yue didn't turn around, but simply nodded slightly to the patrol leader, her voice as clear and crisp as ever: "Open the door."

The patrol leader hesitated for a moment. His gaze passed over Yin Yue's shoulder and landed on the dark gray figure at the cabin door. His tone was cautious: "Your Excellency, according to the rules, all accompanying personnel entering the sect must have their identities verified. This person is…"

The patrol leader tensed slightly for a moment. But he did not back down, only clasping his hands and saying, "This subordinate knows that you are Her Majesty the Holy Maiden's demon slave, but rules are rules. This subordinate dares to ask Her Majesty the Holy Maiden to cooperate with the investigation."

Yin Yue's gaze fell on the patrol leader's face, and she remained silent for a moment. She neither reprimanded nor lashed out, but simply turned her head slightly and spoke to the dark gray figure at the cabin door, her voice colder than before: "Come here."

Li Hanshan stepped out of the cabin and stood by the ship's railing. He concealed his aura, suppressing the spiritual energy fluctuations around him with the Demon Slave Seal. From the outside, all that could be sensed was a faint, chilling aura indistinguishable from that of an ordinary demonic sect servant.

The patrol leader raised his right hand and formed a hand seal. The seal transformed into a dark golden beam of spiritual energy, striking Li Hanshan precisely between the eyebrows. The demonic slave mark planted by Yin Yue on his forehead surfaced under the stimulation of the spiritual energy beam, resembling a dark rune branded onto the surface of his soul, radiating intense demonic energy fluctuations, completely identical to Yin Yue's own spiritual energy mark.

After confirming that the slave's aura was genuine, the patrol leader nodded slightly, withdrew his magic seal, and gestured for the patrolling disciples behind him to let them pass. He then clasped his hands in a fist salute to Yin Yue again: "Your Excellency, Holy Maiden, please."

Yin Yue didn't even glance at him, urging the flying boat through the patrol array and continuing to fly deeper into the heart of the Heavenly Demon Sect.

Li Hanshan stood at the ship's railing, his pure Yang energy flowing slowly through his meridians, calming the Demon Slave Seal, which had been slightly heated after being stimulated. He gazed at the increasingly thick, dark red sky ahead, rapidly calculating the next move in his mind's eye.
