The Eternal Saint of Alchemy

He reached out and pressed his hand on the scales of the stone pillar. The scales sank inward, and with a soft click, a hidden compartment was revealed at the bottom of the pillar, exposing the space inside.

It was a jade slip as thin as a cicada's wing. Xiao Fan took out a jade slip and probed it with his divine sense. The information inside immediately surged in like a tide—this stone palace was the first experimental product designed by the Taixu Pill Saint when he was young to verify his core idea of ​​"using fire to suppress yin".

The red crystal inside the dragon's mouth is the most basic array base. Its function is similar to the Bone Burning Furnace, continuously releasing pure fire-attribute spiritual power to suppress the trace of Yin energy within Prince Shi's body.

The jade slip reads: "This formation has been in operation for over a hundred years. If anyone comes here, they should replace the pure yang flame in the center of the formation with yin-yang fire, so that it can resonate with the other two great formations."

In this way, the three great formations are interconnected, leaving no weaknesses.

He shifted his position. Xiao Fan carefully put away the jade slip, then looked up at the blood-red crystal in the dragon's mouth, his eyes gleaming.

More than a hundred years have passed, and its spiritual power is far less than before. Next, he only needs to cultivate a new fire seed in the Burning Bone Abyss Furnace to replace the original array eye, while ensuring that the seal of the stone hall is not broken.

"I'll be staying here for a while longer," he said, looking at Gu Yuan and Yun Ruoxi. "Once I figure out the flow of spiritual energy within this stone chamber, I'll change the location of the array's core."

Gu Yuan nodded slightly and walked out of the portal with Yun Ruoxi.

Xiao Fan sat cross-legged in front of the dragon pillar, his eyes closed, and slowly probed his divine sense into the bronze array plate on the wall, beginning to sort out the spiritual energy channels of this ancient array.

This process is extremely meticulous and time-consuming, but once completed, the Taixu Dansheng Sealing Network will be fully connected, and the three major array eyes of Qingyun Mountain, Burning Bone Abyss, and the Imperial Capital will spread from the Daqing Empire to the entire continent.

On the third day, Xiao Fan left the portal, spoke to Han Fei, and asked him to ride to the Pill Tower to inform them before setting off. He sent one letter to Ye Ruolin and another to Zhou Yanzhi, saying that a major incident had occurred at Qingyun Mountain and that they urgently needed manpower, urging them to come immediately.

Five days later, Ye Ruolin arrived travel-worn from the foot of the mountain. Upon seeing him, she immediately dismounted and looked around. "Only a few words were exchanged; what exactly happened?"

Xiao Fan led her to an open space and told her the location of the underground stone palace. Ye Ruolin crossed her arms, looking thoughtful.

"Didn't you already test it in the Burning Bone Abyss? What he needs to do now is move the array eye into the new array, so that the stone hall cannot be sealed temporarily, and the Yin energy below will naturally rebound. Someone must simultaneously reinforce the seal outside the stone hall."

Xiao Fan nodded, remaining silent. This was also the reason he summoned Ye Ruolin; the Ye family was quite accomplished in Yin Fire Barriers and was particularly adept at reinforcing restrictions.

The next day, Zhou Yanzhi brought a box of old scrolls and a large hammer. Although this guy was not good at fighting, he was first-rate at engraving runes and assisting with formations.

After the three met and exchanged a few pleasantries, Xiao Fan briefly explained the mission and then led Lin Huang and the other two through a portal of light that afternoon.

Zhou Yanzhi glanced at the bronze plaque hanging on the wall, a glint of shrewdness flashing in his eyes, and muttered something to himself.

Ye Ruolin walked around the stone hall again and again. Every so often, she would squat down and use her fingers to draw marks on the stone wall.

"The structure of this seal has surprised me somewhat." Ye Ruolin stood up, dusted off her clothes, and said, "Change your clothes in fifteen minutes. I'll be watching over you."

Xiao Fan stood in front of the coiled dragon pillar, looking at the last step recorded on the jade slip. A Thunderfire Token hung at his waist, and a ball of dark golden flame on his chest was ready to be unleashed.

"Tonight, Brother Zhou, you will monitor the spiritual energy fluctuations of this array plate. If anything seems amiss, report to me immediately. Ruolin, first set up a barrier in the hall, and you can activate it when I give the order."

Zhou Yanzhi nodded, and Ye Ruolin nodded. Xiao Fan glanced at the white jade dragon pillar, then at the red crystal in the dragon's mouth, which had been operating for a hundred years.

After tonight, the three great formations will merge into one.

As night deepened, the bronze plaque in the stone hall had become dim and lost its luster, yet it still shone brightly.

Xiao Fan stood before the dragon pillar, took a deep breath, and stretched out the dragon's mouth. The flames of creation enveloped the originally bright red core of the array, and slowly pulled it out.

As the core of the formation rotated, all the runes on the walls of the entire hall lit up. A faint, almost imperceptible chill seeped out from the cracks beneath the stone pillars, like a flood that had been suppressed for many years suddenly breaking through a breach.

Outside the stone hall, Ye Ruolin had already set up a barrier, placing one hand on the outside to block the invasion of the cold air.

Xiao Fan did not stop.

With its other hand, it used the dark gold fire that it had been refining in the Burning Bone Abyss for several days. Under the harmony of yin and yang, it transformed into a ball of light that was exactly the same as the center of the original magic array, and disappeared into the dragon's mouth in a flash.

As the new array core descended, the white jade dragon pillar suddenly burst forth with boundless golden light. Each scale seemed to come alive, opening and closing slightly before returning to silence.

The rune discs on the wall lit up simultaneously. The chilling aura that had been seeping from the cracks had vanished, replaced by a layer of pale golden patterns, as if it had just been infused with spiritual energy.

Xiao Fan stood still, sensing that the array base within the dragon's mouth had connected to the new array base. The three array eyes—Qingyun Mountain, Burning Bone Abyss, and the Imperial Capital—simultaneously lit up.

"It's done." He looked at Ye Ruolin and Zhou Yanzhi and said calmly, "All three formations will be deployed simultaneously!"

Zhou Yanzhi walked to the nearest array plate, squatted down, looked at the data on it, wiped away his sweat, and a smile appeared on his face. "My spiritual power cultivation has increased by thirty percent, very steadily, much smoother than expected."

Ye Ruolin withdrew her hand, shook her numb fingers, looked at Xiao Fan, raised her eyebrows slightly, and asked, "Who are you?" "So what? What kind of effect will these three things have when combined?"

Just as Xiao Fan was about to say something, the entire stone hall began to shake, and a terrifying pressure descended upon it.

A deep, resonant hum came from the depths of the earth, as if something enormous was rolling within it. The golden light on the white jade dragon pillar grew stronger and stronger before finally stabilizing.
