Hunter and prey, you know how to deliver treasure!

Xiong Kaishan grinned, revealing a mouthful of ghastly white teeth: "Haha... You want me to go? That Black Stone City is a dragon's pool and tiger's den now, why don't you go, Situ Piaomiao?"

The four of them were all old monsters who had lived for hundreds of years; no one was willing to do anything without benefits.

"To infiltrate Black Stone City, we must first break through the City Protecting Grand Array," Murong Yue pondered aloud. "I can provide a World-Breaking Divine Talisman, sufficient to tear a silent and invisible gap in their City Protecting Grand Array. This Talisman can be used three times; entering this Black Stone City once is enough."

Ji Wushuang spoke indifferently: "I can provide Soul-Corroding Incense. This poison can corrupt a person's Divine Soul, and it spreads incredibly fast. Using it against a Foundation Establishment junior is foolproof."

"Very well," Situ Piaomiao finally said. "I will add a 'Breath Concealing Veil'. It can completely conceal all your aura and fluctuations, making it difficult even for a Nascent Soul Divine Sense to detect. After the matter is accomplished, this treasure will belong to Fellow Daoist Xiong. With this, is Fellow Daoist Xiong willing to give it a try?"

These three items were each worth a fortune.

A flash of greed crossed Xiong Kaishan's eyes as he calculated rapidly in his heart. Given his Cultivation, even if he failed, it wouldn't be difficult to escape.

"Deal!" He slapped his chest. "I've long wanted to go twist off that brat's head and use it as a chamber pot!"

...

After sending off Ye Youmeng and Xuan Yin, Lin Yuan immediately returned to the Quiet Room.

He did not rush to study the Pill Formula, but instead took out all the mountain of Materials that Ye Youmeng and Xuan Yin had contributed.

"The Materials are enough, but unfortunately, the grade is a bit lacking. It is beyond my ability to set up a First-Grade Grand Array that combines offense and defense."

Lin Yuan rubbed his chin, a shrewd light flickering in his eyes.

"However, it is more than enough to set up a top-tier trapping array."

He was cautious by nature and had always believed in the philosophy: "If you can't beat them, run; if you can't run, hide." A killing array was indeed powerful, but his own safety came first.

The Earth Core Nether Fire roared, and the terrifying high temperature instantly distorted the light in the Quiet Room.

Pieces of rare Ore were tossed into it, rapidly turning into colorful Spiritual Liquid.

Lin Yuan was focused, his Divine Sense manipulating the Spiritual Liquid, fusing them according to a certain profound ratio, then rapidly shaping and cooling them.

His movements were fluid and natural, full of the beauty of a naturally formed dao rhyme.

Soon, three hundred and sixty-five palm-sized black Formation Flags, along with a pitch-black Formation Plate engraved with countless complex patterns, were refined.

"Go!"

Lin Yuan flicked his long sleeves, and the three hundred and sixty-five Formation Flags turned into streaks of light, silently merging into every corner of Tingfeng Courtyard, perfectly combining with the previous Heavenly Cycle Spirit Gathering Grand Formation.

Hum—!

The space of the entire Tingfeng Courtyard seemed to solidify for a moment, becoming immensely heavy.

"This array is called the 'Heavenly Cycle Star Constellation Dragon Trapping Array'. The Materials are solid, and the technique is exquisite. Not to mention an Early Stage Nascent Soul, even a Late Stage Nascent Soul Cultivator would find it impossible to escape for a while once trapped inside."

Having set all this up, Lin Yuan finally felt completely at ease.

Only then did he take out the Jade Slip recording the "Nine-Turn Purple Gold Pill" and began to study it carefully.

"The train of thought is good, but unfortunately, it took a wrong turn."

In just a moment, Lin Yuan pointed out the flaws in the Pill Formula with pinpoint accuracy.

In the eyes of this First-Grade Alchemist, this ancient incomplete formula was like a student with severe academic imbalances; both its strengths and weaknesses were equally prominent.

He immediately began to improve the Pill Formula.

With his current attainments in Alchemy, completing and optimizing an incomplete formula was simply a task he could perform with ease.

Just half an hour later, a brand new Pill Formula had taken shape in his mind.

Not only had the medicinal efficacy not weakened, but due to the structural optimization, it had increased by at least thirty percent!

In high spirits, he immediately started the furnace for Alchemy.

Two hours later, two Medicinal Pills, purple-gold all over, the size of dragon eyes, and with nine miraculous pill patterns on the surface, were freshly produced.

Lin Yuan put away the Medicinal Pill and stretched his muscles. "I was so busy working that I almost forgot the main business!"

He took out a Sound Transmission Talisman, his voice carrying a hint of playfulness: "Meiniang, the night is deep. I have recently gained some insights into the Yin and Yang Dao. Come quickly to Tingfeng Courtyard, shall we have an in-depth discussion?"

...

Three days later, early morning.

Ye Youmeng arrived as promised.

She was still wearing a beautiful, colorful dress of ten thousand poisons, but her stunningly beautiful face carried a hint of expectation and nervousness that was difficult to conceal.

The Old Ancestor Xuan Yin also accompanied her.

"Fellow Daoist Lin, everything is ready." Ye Youmeng's voice was slightly hoarse.

Lin Yuan nodded. Without any unnecessary chatter, he directly handed over the two purple-gold Medicinal Pills: "This pill is called the Nine-Turn Purple Gold Pill; it is an improvement I made based on your incomplete formula. The medicinal efficacy is more than thirty percent stronger than the original version. One pill for each of you two Fellow Daoists."

Ye Youmeng and Xuan Yin took the Medicinal Pills. Just the nine miraculous pill patterns circulating on the Medicinal Pill caused her heart and soul to shake violently. She could clearly feel the terrifying Spiritual Qi contained within this Medicinal Pill.

"Many thanks!" She thanked Lin Yuan solemnly, her soul-stirring, charming eyes now filled with gratitude.

"Enter the Quiet Room first and prepare for the Breakthrough." Lin Yuan pointed to the Quiet Room in the main courtyard. "Senior Xuan Yin, please trouble yourself to act as the Protector outside, just in case."

"Rest assured, Fellow Daoist Lin!" The Old Ancestor Xuan Yin nodded solemnly.

Ye Youmeng took a deep breath, hesitated no longer, turned, and walked into the Quiet Room, sitting cross-legged. Then, she tilted her head back and swallowed the Medicinal Pill.

A terrifying medicinal force that seemed capable of burning everything to ash exploded within her body!

Even with her Middle Nascent Soul Stage Cultivation, she was jolted by this force, her beautiful body shaking violently. Her eyes were filled with excitement; this massive impact force would absolutely be able to break through her Bottleneck.

Lin Yuan sat cross-legged opposite her, hands forming seals, triggering the Heavenly Cycle Spirit Gathering Grand Formation.

"Rise!"

In an instant, the Spiritual Qi in Tingfeng Courtyard formed a tide of Spiritual Qi, turning into a massive, deep blue tornado that pierced into Ye Youmeng's body!

The sky over the entire Black Stone City changed color, and thunder rolled.

A terrifying pressure, far exceeding that of an ordinary Early Nascent Soul Stage Cultivator, began to brew between heaven and earth.

"What an overbearing method!" Old Ancestor Xuan Yin watched with a palpitating heart.

Just as everyone's attention was drawn by this earth-shattering scene of the Breakthrough.

Outside Black Stone City, a blurred figure that had almost merged into the darkness silently approached the light curtain of the City Protecting Grand Array.

It was none other than Xiong Kaishan from Hundred Beasts Mountain!

In his hand, he held a silver Talisman covered in mysterious runes; it was Murong Yue's World-Breaking Divine Talisman.

He pressed the divine Talisman onto the light curtain. Without making a single sound, the light curtain split open like melting ice and snow, creating a gap just wide enough for one person to pass through.

Xiong Kaishan did not hesitate in the slightest, his figure flickering as he slipped inside.

He was draped in a light veil as thin as a cicada's wing, which completely concealed all his aura, even the sounds of his heartbeat and blood flow; it was Situ Piaomiao's Breath Concealing Veil.

After infiltrating the city, Xiong Kaishan did not rush to act.

Like the most experienced old hunter, he patiently lurked in the shadows, a glint of greed and vigilance flickering in his small eyes.

"Such rich Spiritual Qi! This array... it truly is a work of divine craftsmanship!" He was shocked in his heart, and at the same time, greed surged within him.

"Those idiots, they sent me here to kill! What a pity to kill such a person. If I could capture the person who set up the array and plant a Restriction on them, why would my Hundred Beasts Mountain have to worry about not uniting the Eastern Region!"
