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

When Yin Yue entered the cave, Li Hanshan was standing in the center of the stone chamber, the unsealing jade slip in his hand already put back into his sleeve.

He sensed Yin Yue's presence emanating from the cave entrance and also realized that the people outside had left, leading him to roughly guess what had just transpired outside.

Yin Yue emerged from the passage, her face beneath the silver veil revealing no obvious emotional fluctuations. However, the spiritual energy emanating from her body was slightly more taut than when she left, like a bowstring that had been moderately stretched but not yet fully released.

"What is it?" Li Hanshan asked.

Yin Yue walked to the stone platform, took out the "Saint" token from her sleeve, and placed it on the stone surface in a slow and unhurried manner.

She sat down on the stone bench, picked up the cup of now-cold spiritual tea from the stone table, took a sip, put it down, and spoke, her tone returning to its usual clear and calm tone: "It's nothing. Just some petty scoundrels."

She paused, her gaze falling on the array positioning lines that Li Hanshan had already carved on the stone chamber floor. After a moment of silence, she continued, "How many arrays have you set up over there?"

"The seventh one," Li Hanshan said truthfully, "has been embedded and is currently calibrating the spiritual energy circulation between it and the previous six. The calibration should be completed in another day or two, and then we can start working on the eighth one."

Yin Yue nodded slightly.

She stood up, walked from the stone platform to the edge of the rock wall on the east side of the stone chamber, which Li Hanshan had polished with his spiritual power. She squatted down and gently brushed her fingertips along the surface of the array artifact that was already embedded in the groove, as if sensing the connection between the array artifact and the original spirit-gathering array patterns of the cave.

After a moment, she withdrew her hand, stood up, walked back to the stone platform, and sat down again.

"Continue setting up the array." She spoke, her voice as steady as ever, revealing no lingering emotion. "Before the array is complete, anything can happen. Although the Enforcement Hall has been dealt with this time, Ye Feiyan may not give up. She won't act openly, but she has plenty of ways to send messages to places where they shouldn't be. Every day you delay, the risk of the teleportation array being exposed increases."

Li Hanshan nodded slightly and did not ask any further questions. He walked to the array device embedded in the rock wall, squatted down, and condensed his divine sense into an extremely thin thread, slowly traveling along the spiritual energy loop between the seventh and sixth array devices.

The trajectory and flow rate of that loop deviated slightly from his previous calculations, requiring subtle adjustments at several key points using pure Yang energy. He focused all his attention on those points and began to calibrate them one by one.

Over the course of three months, he renovated almost every inch of the cave floor and every rock wall.

The teleportation array's components were eventually embedded in the floor of the central stone chamber, arranged in a ring, like twelve stars simultaneously ignited lying quietly in dark blue rock. Each component was positioned at a suitable angle to the direction of the earth's ley lines, neither completely detached nor generating any spiritual energy connection with them.

The moment the twelfth array device was embedded in the ground, the spiritual energy loop of the entire teleportation array finally formed a complete closed loop.

He crouched at the edge of the array's core, using his divine sense to perceive the stable flow of spiritual energy between the twelve array artifacts.

The cycle was like a clock that had been repeatedly adjusted, with each gear precisely meshing with the pitch of the next. The silvery-white light on the surface of the teleportation array receded into a thin layer of glaze, adhering to the surface of each array device, quietly settling into the dark blue background of the stone chamber floor.

He stood up, stretched his knees which were slightly stiff from squatting for so long, and turned around. Yin Yue was standing at the entrance of the passageway to the side of the stone chamber, her silver veil gleaming coolly in the light of the luminous pearl.

During these three months, she hardly disturbed him. Every day, she would sit quietly by the stone platform and read the jade slips. Occasionally, she would hand him a cup of spiritual tea while he was meditating, and then return to her seat to continue in silence.

"The formation is set up." Li Hanshan said, his voice slightly hoarse than it had been three months ago, a natural consequence of the continuous depletion of his divine sense.

Yin Yue put down the jade slip in her hand and walked to the center of the stone chamber. Her gaze swept over the twelve array artifacts one by one, like a ruler that had been repeatedly calibrated measuring the direction of each line.

After a moment, she nodded slightly: "The spiritual energy circulation is very complete, and the response frequencies between the array artifacts are also aligned. Your array-setting skills are indeed more refined than those of ordinary array masters."

She paused, then looked away from the array and onto Li Hanshan's face: "Can it be activated now?"

Li Hanshan did not answer immediately.

He crouched down again, placed his palm on the ground at the edge of the array eye, and channeled spiritual energy from his palm into the base of one of the array artifacts, gently touching the activation node embedded deep within the artifact.

The silver-white patterns on the surface of that array artifact lit up for a moment, and then the patterns on the surfaces of the other eleven array artifacts lit up one after another, like a string of lamps being strung together.

The light from the entire teleportation array gradually increased in intensity, eventually converging into a silver-white pillar as thick as an arm. This pillar slowly rose from the center of the array's core, casting a straight line of light through the void.

When the beam of light reached its highest point, it did not continue upwards but hovered in mid-air, like a fixed thread, trembling slightly in the void.

Li Hanshan used his divine sense to perceive the suspended pillar of light and confirmed that the intensity of the spatial fluctuations contained within it was extremely weak, like tiny ripples on the surface of a lake ruffled by the wind, almost imperceptible to the outside world under the cover of the cave's restrictions.

Then he slowly withdrew his spiritual power, pressing the pillar of light back into the array's core. The light of the teleportation array receded layer by layer, eventually returning to its initial quiet and stable state.

"The connection is working." He stood up, brushing the fine stone dust off his hands. "The alignment of the array devices and the isolation of the ley lines have been achieved. The teleportation channels at both ends are technically connected."

Yin Yue stood before him, her gaze, hidden beneath a silver veil, fixed on his face: "Then why not activate it?"

"Because it can't be hidden once it's activated." Li Hanshan leaned against the stone wall, his tone calm. "The spiritual energy loop of the teleportation array can be completely isolated from the earth's veins, and it can be driven by spirit stones to avoid being detected by the Heavenly Demon Blood Array. But once the teleportation channel is officially established, the space between the two array eyes will experience a fluctuation that cannot be concealed."

He paused, his gaze falling on the dark blue dome above his head. "Although the mark is very faint, the Heavenly Demon Blood Array is connected to the entire earth vein of the Heavenly Demon Sect. Any abnormal fluctuations will be automatically recorded and reported by the array. Given the sensitivity of the Heavenly Demon Blood Array, that mark will be detected in a very short time, and even the Void Refinement and Dao Integration experts of the Heavenly Demon Sect will personally investigate it."

Yin Yue remained silent for a moment.

She was well aware of the significance of a Dao Integration cultivator from the Heavenly Demon Sect. No detail, no matter how small, could escape his notice within the entire Heavenly Demon Sect's territory.

Although the spatial fluctuations caused by the activation of the teleportation array were small, in the perception of a Dao Integration cultivator, the fluctuations were like a lamp suddenly lit in the dark night, making it difficult to miss.

"Are you sure?" she asked, her voice a few decibels lower than before.

Li Hanshan nodded: "Confirmed."

How long does it take to boot up?

"The connection will be quick, it will only take the time it takes for an incense stick to burn," Li Hanshan replied truthfully. "The alignment of the array devices is already done. All that's left is to activate the array eyes at both ends and lock their coordinates together. Once the coordinates are locked, the spatial channel will form instantly, but it will take the time it takes for an incense stick to burn to be fully connected."

He finished explaining the details one by one, then looked at Yin Yue: "So, I can set up the formation, but you need to solve the problem of concealing it at the moment of activation. You have to find a way to divert the Heavenly Demon Sect's attention. Even if it only takes the time it takes for an incense stick to burn, that will be enough."
