Brother Yuan, you've gotten even more amazing!

This kind of Heaven and Earth Spiritual Fire is a highly coveted treasure for any Cultivator, and for an Alchemist, it is an Opportunity that can fundamentally transform their Alchemy Skill.

He was preparing to go to the perilous Demon Falling Valley. If he could obtain this Earth Core Nether Fire and combine it with his Fire Control Technique, his strength would surely increase greatly.

However, to be safe, Lin Yuan still asked, "Are you sure there is only one Crimson Flame Lizard there?"

"I personally saw the Earth Core Nether Fire. There is indeed only that one Yao Beast guarding it. As long as we kill it, the Spiritual Fire will be within easy reach."

Seeming to notice Lin Yuan's doubts, Wei He sighed and revealed an even bigger secret.

"I know Brother Lin is wondering why a treasure like the Earth Core Nether Fire would be discovered by a mere Qi Refining Cultivator like me."

"Speaking of which, have you ever heard the name of the Yin Corpse Old Ancestor from over a hundred years ago, Brother Lin?"

Lin Yuan's heart stirred.

"I have naturally heard of him. Legend says this Old Ancestor was once the Peak Master of Green Bamboo Peak, and later even advanced to the Nascent Soul Stage, but eventually his Lifespan ran out and he passed away."

"That's right."

A hint of arrogance appeared on Wei He's face.

"That Yin Corpse Old Ancestor is the ancestor of my Wei Family. This Earth Core Nether Fire was accidentally discovered by my revered ancestor during one of his travels."

"However, the fire hadn't fully formed at the time, and its fire nature was volatile and difficult to collect. So, the ancestor set up a Concealment Grand Formation here, completely sealing the area. Only descendants bearing my Wei Family Bloodline can enter with a Token."

So that was it.

The last trace of doubt in Lin Yuan's heart vanished.

This explanation was logical and perfectly accounted for why the Earth Core Nether Fire had not been discovered by others until now.

With a Formation set up by a Nascent Soul Old Ancestor, plus the Bloodline restriction, this Opportunity was indeed secure.

It seems the Earth Core Nether Fire truly exists, and aside from that Crimson Flame Yao Lizard, there aren't many other dangers.

This trip is worth making.

"Alright."

Lin Yuan finally nodded.

"You should focus on healing first. Once your injuries are recovered and you successfully upgrade your Ironclad Corpse, we will set off."

"I will also take this time to prepare properly."

Afterward, the two discussed some details carefully, and only then did Lin Yuan get up, bid farewell, and return to his residence.

Han Shuang had already prepared breakfast and was sitting quietly by the Stone Table, waiting for him.

After Han Shuang served Lin Yuan breakfast, he immediately plunged into the East Wing Room and did not come out again.

The rising furnace fire illuminated his aged face, making it flicker between light and shadow.

One day later.

Lin Yuan placed a Medium Grade condensing yuan pill into his mouth.

As soon as the Medicinal Pill entered his throat, it transformed into a pure, gentle warm current that flowed freely through his dry Meridians, finally converging in his Dantian.

A moment later, Lin Yuan's body trembled slightly.

He opened his eyes, and a difficult-to-suppress look of joy appeared on his aged face.

The Eighth Layer of Qi Refining was successful.

"From the Eighth Layer of Qi Refining to the Ninth Layer of Qi Refining, eight hundred Attribute Points are needed."

"One High Grade condensing yuan pill can provide forty points. Calculating it, only twenty pills are needed."

"Continue Alchemy to push my Cultivation to the Ninth Layer of Qi Refining!"

He closed his eyes again, sinking his entire focus into the Pill Furnace before him.

Time flew by.

In the blink of an eye, another five days passed.

The door creaked open, and Lin Yuan stepped out, full of vigor.

Days of sleepless effort did not make him look tired; instead, the light in his eyes shone even brighter.

Just now, he successfully achieved a Breakthrough and officially stepped into the realm of the Ninth Layer of Qi Refining.

At this moment, Han Shuang was Cultivating the Golden Body Art in the courtyard; every punch and every kick carried a fierce Qi.

Upon seeing Lin Yuan, the determination on her face instantly melted away, replaced by surprise.

She quickly stopped her practice and rushed over, hugging Lin Yuan's arm, her face filled with deep affection.

Lin Yuan looked at her, scooped her up in his arms, and turned to walk back into the room... One hour later.

"Brother Yuan, I feel like you've changed again."

Han Shuang lay languidly on Lin Yuan's chest and spoke softly.

"How have I changed?"

"You've become... more powerful."

Han Shuang whispered.

"You're not bad either."

Lin Yuan's gaze fell upon her.

"Are you at the Second Layer of the Copper Skin Realm now?"

Now, every time Han Shuang undergoes arduous Cultivation, she can provide him with four Attribute Points.

This investment yields a considerable return.

"It's all because Brother Yuan uses Medicinal Pills without regard for the cost. Otherwise... Shuanger how could possibly progress so quickly?"

Han Shuang's voice was filled with gratitude.

Lin Yuan smiled and took out a Porcelain Bottle from his Storage Pouch, handing it to her.

"There are thirty qi gathering pills inside. Cultivate well."

Han Shuang took the Porcelain Bottle, and mist immediately gathered in her eyes.

"Thank you, Brother Yuan."

"Why are you crying?"

Lin Yuan reached out and patted her head.

"I only found out two days ago that this kind of Medicinal Pill actually costs four Spirit Stones per piece."

"Here in the Yin Corpse Sect, most low-level Immortal Masters don't even earn that many Spirit Stones in a month."

Han Shuang's voice trembled slightly.

"Brother Yuan, you are too good to me."

"Did you hear that from Su Qingyan?"

Lin Yuan's movements paused slightly.

Han Shuang nodded.

"In the past two days, Immortal Master Su... she suffered quite a bit. That Immortal Master Wei frequently struck and beat her..."

Lin Yuan's heart tightened.

Their two homes were separated by only a wall, so he naturally knew that while Wei He and Su Qingyan couldn't be called affectionate in the past, they were respectful of each other, and he had never heard of Wei He striking her.

Could it be that his affair with her had been discovered?

"The last couple of days, I went to consult Immortal Master Su about Spirit Plants, and I happened to run into Immortal Master Wei yelling at and hitting Immortal Master Su." Han Shuang's body trembled slightly.

"The day before yesterday, I even saw several bruises on Immortal Master Su's wrist..."

"She said that Immortal Master Wei found the qi gathering pills she had secretly hidden, and that's why he hit her... It was only from her that I learned how valuable these Medicinal Pills are."

"Brother Yuan, you didn't give me all the Medicinal Pills you refined, did you!"

"Don't let your imagination run wild."

Lin Yuan patted her head, interrupting her thoughts.

"I haven't had a proper meal in days, and my mouth is getting bland. Go prepare something to eat."

"Okay..."

Han Shuang agreed, quickly put on her clothes, and left the room, blushing.

Lin Yuan watched her retreating figure and sighed softly.

Regarding Su Qingyan's matter, he didn't seem to have any reason to intervene.

He shook his head, throwing this distraction out of his mind, and took out a Paper Crane folded from light golden Talisman Paper from his Storage Pouch.

Spiritual Power was injected from his fingertip.

The Paper Crane's wings began to flutter slightly, as if it had come alive.

"Senior Sister Mu, the Alchemist has agreed, but some details still need to be discussed."

Lin Yuan spoke softly to the Paper Crane.

He let go, and the Paper Crane transformed into a streak of light, instantly flying out the window and disappearing into the horizon.

Currently, his apparent Cultivation level was still the Fifth Level of Qi Refining.

His actual Cultivation, however, had already reached the Ninth Layer of Qi Refining.

Since he was going to seize the Earth Core Nether Fire, he naturally had to make thorough preparations.
