The Eternal Saint of Alchemy

The dark gold patterns on the surface of the metal shell began to spin rapidly at a speed visible to the naked eye the moment they came into contact with the light sphere, gradually forming a halo.

Line after line of text, as thin as a hair, made of light, floated in mid-air and slowly arranged itself.

"The Nine Towers seal off the outside world, burning bones and melting bodies; between you and me, this is a catastrophe!"

The three lines of moonlight form a ring, hidden from view. If future generations come here, they can use the Fire of Creation as a key to open this formation. Once the formation is complete, the Yin energy will be contained within the earth's core, and for a hundred years, no one will disturb it.

Xiao Fan read on, word by word, and the more he read, the more shocked he became. After reading this, he was completely stunned.

This light sphere array eye is the most basic safety measure in the entire sealing system of the Grandmaster of the Void. Once activated, it will automatically start, continuously gathering the Yin energy that is constantly dissipating from the ground to the core for sealing.

To activate it, you need not only the Fire of Creation, but also the dark golden flame deep within the Burning Bone Abyss as a medium.

He took out a small jade bottle, took out a wisp of dark golden flame, and carefully placed it inside. When the Creation Fire touched the dark golden flame, the originally dark purple core suddenly shone brightly, and a faint golden halo spread outward.

The array patterns on the entire hall floor lit up one by one, with the light spreading outwards from the center of the sphere, extending in all directions along the patterns carved on the stone slabs.

Just then, Xiao Fan suddenly felt the ground tremble, as if the spiritual veins beneath the capital had awakened.

He withdrew his hand and stepped back. A dark golden ripple spread outwards steadily, and when it touched the wall, it would return to the wall, repeating this cycle until it formed a closed loop.

The last line of defense left by the Grandmaster of the Void Pill was activated once again, and this time, it was truly a great success.

Xiao Fan stood in the hall and waited until all the array diagrams lit up before turning around and walking towards the stone steps.

When he returned to the sewers, Zhou Yanzhi was already waiting at the door. Seeing that he was alright, he finally breathed a sigh of relief. He asked, "How are you?"

"He's alive," he uttered. Xiao Fan clapped his hands and said, "The array's core has been activated. For the next five years, we will have no worries."

Zhou Yanzhi's eyes lit up, and without asking any further questions, he followed him back the way they came. By the time they emerged from the drainage outlet, it was already quite late. Ye Ruolin was already waiting under the old locust tree outside the warehouse area's wall. Upon seeing the two of them come out, she immediately came to greet them.

"What's going on?"

Xiao Fan briefly explained the situation at the array's core. Ye Ruolin thought for a moment, then gently patted his shoulder. "Okay. Let's go back for a drink after we're done."

Master Gu Yuan was warming wine in the tavern, drinking it in large gulps. Back at his lodgings, Xiao Fan plopped down in a chair, the warm wine sliding down his throat. Outside, it was pitch black, but brightly lit.

The array's core returned to normal, and the array foundation in the sea of ​​consciousness also stabilized considerably. Layers of dark golden spiritual energy halos enveloped the dark purple moon core, floating silently beneath the capital city.

From then on, breathing underground in this city had an additional layer of protection.

During the few days since the array's core was activated, Xiao Fan did not rush to leave the capital, but chose to stay.

He used the old jade slips he borrowed from the Zhou family and the cultivation techniques from the Burning Bone Abyss to make a preliminary understanding of the Yin-Yang Fire. Every day, he would make new discoveries and revisions, and the originally somewhat vague theoretical framework gradually became clearer.

These days, Zhou Yanzhi comes here almost every afternoon. Sometimes he brings new manuscripts, sometimes he just sits down and chats. His fervor for the Yin-Yang Fire Harmony System has reached an almost insane level.

Seeing his serious expression, Xiao Fan explained some basic chapter content to him.

After Zhou Yanzhi returned, he read it over and over again. When he came back the next day, he was able to retell the entire content and even give two or three insightful conclusions.

Xiao Fan nodded slightly. He was exceptionally talented and had a solid foundation. He was destined for greatness.

Old Hu also sent someone to tell Xiao Fan that if the two ancient books were useful to him, they would not have to be returned.

Xiao Fan had someone deliver a bag of fire-attribute spiritual materials as a return gift from the Pill Tower. Although the items were not valuable, their quality was excellent. After accepting them, Elder Hu sent someone to tell him, "You're young and impetuous, so be cautious in your actions."

That night, Xiao Fan finished writing the first draft of "The Beginner's Guide". He read it from beginning to end, and after confirming that the logic and steps were correct, he wrote "Introduction to Yin-Yang Fire" on the title page.

I closed the booklet and placed it on the table; it was already getting dark.

He stood by the window, the evening breeze carrying wisps of smoke rising from the alleys of the capital. At dusk, the rooftops of the imperial city were cast in a deep blue shadow, and the entire city was shrouded in a tranquil and solemn atmosphere.

Ye Ruolin walked out of the courtyard, carrying a food box in her hand. She looked up at the window, then shook the food box in her hand.

"Today, the Ye family's cook made braised pork hock. I was thinking that you've been eating bland and tasteless food at the inn these past few days, so I brought a box over."

Xiao Fan came downstairs with a smile on his face. The two sat down at the stone table in the backyard of the inn and took out the side dishes from the food box. The fragrant braised pork knuckle, with a dish of pickled cucumbers and two bowls of steaming rice, was simply delicious.

"When are you going back to Danta?" After finishing her meal, Ye Ruolin picked up her teacup, took a sip, and asked.

Xiao Fan swallowed the rice in his mouth, lost in thought. "Alright, then you can stay here for a few days. I'll go through the basics with Brother Zhou, covering a few key stages, before I go into seclusion. As for the second half of the Burning Bone Abyss, I've only memorized the general outline; I'll have to digest the rest slowly."

Ye Ruolin nodded slightly. "Alright, I brought a batch of fire-attribute ores for you to see this time. Some of them are quite special, but I don't know what they're used for."

"Okay." He readily agreed.

The moon was high in the sky, and the courtyard was quiet except for the sound of the wind rustling the locust leaves. The two drank tea and talked about the weather in the capital and their observations of the city. The evening breeze carried the aroma of tea mixed with the fragrance of locust blossoms.

Three days before arriving in the capital, Xiao Fan went to the old bookstore in the north of the city.

According to Zhou Yanzhi, there is an old man here who sells antiques. He has collected many years ago the handwritten notes of a wandering cultivator. Although they are severely damaged, some are still missing.
