Mortal: Fairy Song Yu has issued you a task.

Chapter 48, "The Great Luo Illusion Technique," is in hand.

The next morning.

The head of the Shen family was hunched over his desk in his study, sketching and planning, when suddenly there was a knock on the door.

Lin Jingchu: "Greetings, Patriarch Shen. My senior sister and I have come to say goodbye."

Upon hearing this, the head of the Shen family rose and opened the door: "Are you two about to depart already? Or won't you stay a few more days?"

"We have been away from the sect for too long, and I fear my master will worry. It would be best if we returned as soon as possible."

"We have been busy with clan affairs recently, so please forgive us if we have not been able to entertain you properly."

"You flatter us, Patriarch. We have been the ones who have troubled you the most." Lin Jingchu said, taking out a jade slip and handing it over. "This jade slip contains secrets. Please read it by yourself tomorrow."

He joined forces with Song Yu to add multiple layers of restrictions to this jade slip, with the seal lasting for twelve hours. Once the time limit was up, the restrictions would automatically dissipate.

Even if Patriarch Shen, out of curiosity, sought out a formation master to forcibly break the seal, only a master formation expert whose skill far surpassed theirs could break the restriction in a short time. Even so, breaking the seal would still take seven or eight hours.

By then, he and Song Yu had already fled far away.

The jade slip contained his warning that Qin San Niang was suspected of being a demonic cultivator in disguise.

The head of the Shen family casually put the jade slip into his storage bag: "I order Steward Shen to escort the two of you out of the city."

Lin Jingchu declined, saying, "There's no need to trouble ourselves. We have other matters to attend to." With that, he and Song Yu bowed to each other and formally took their leave.

The two then left the Shen residence, but instead of heading straight to the Qin residence in the east of the inner city, they turned towards the outside of the city.

As they approached the city's border, the flying boat suddenly came to a stop, and the two of them plummeted to the ground. After landing, they walked straight into a large cloth shop on the side of the street.

Located on the border and at an important ferry crossing on the Tongjiang River, Tiantong City was a thriving commercial center. Its shops displayed a variety of silks and satins, some vibrant and eye-catching, others simple and elegant, and still others luxurious and opulent.

Song Yu raised his hand and pulled out a piece of blue-green fabric. His fingertips brushed across the surface of the fabric, revealing subtle cloud and rosy patterns hidden within its texture. The fabric was soft, smooth, and firm.

"This material is of superior quality. If you like this color, junior brother, I will use it to make you a new garment."

"No matter what color it is, as long as it was made by my senior sister, I will cherish it."

A smile appeared on Song Yu's lips, as gentle as a spring breeze and the blossoming of pear blossoms.

"Then when we get back safely, I... umm~ umm~"

Before she could finish speaking, Lin Jingchu stepped forward and covered her mouth tightly: Senior sister, you can't say such things!

After purchasing the cloth, the two took to the air again, leaving the city, but then went their separate ways.

Song Yu went alone to Phoenix Perch Mountain, while Lin Jingchu turned back and headed straight for the Qin residence.

Just as the two parted ways, a bearded, well-dressed martial artist strolled out of the back door of the cloth shop and followed the crowd out of the city.

"The mundane art of disguise, which I haven't used for many years, has come in handy here."

This martial artist was none other than Lin Jingchu himself. He disguised himself as an ordinary mortal by using his vertical pupils.

Knowing the other party's background, he naturally couldn't risk it himself. The one sailing towards the Qin residence at this moment was merely his illusory clone.

As long as the distance between this clone and the main body is no more than fifty miles, the clone can last for four or five hours, which is enough to complete the task of setting up the formation.

Qin Mansion in Tiantong City.

Lin Jingchu hadn't even finished his cup of tea in the main hall when Du Dong swayed in with an air of nonchalance.

"Fellow Daoist Lin has arrived early." Behind him followed the cultivator surnamed Zhao and an elderly man with white hair and beard.

"As entrusted by the fairy, I will do my best to complete it as soon as possible." Lin Jingchu stood up and greeted her with a smile.

"In that case, I won't keep you any longer for our chat. I have important matters to attend to and cannot accompany you personally." Du Dong turned to the white-haired elder beside him. "Elder Qin, please take Fellow Daoist Lin to the Class B spirit mine to set up the array."

The white-haired old man bowed deeply: "I obey your command. Fellow Daoist Lin, please follow me immediately."

Lin Jingchu nodded to Du Dong and then left with Old Qin.

Only Du Dong and the cultivator surnamed Zhao remained in the waiting hall. Du Dong lightly waved his fan, but his tone was icy: "Let's make our move. Since that Qin family head won't listen to reason, then he'll have to suffer the consequences. Once we have the goods and this charade is over, we'll leave."

……

The Qin family's spiritual mine, which I visited yesterday.

After Lin Jingchu and Qin Lao had their identities verified by the mine guards, they passed through the protective array and landed in front of the giant stone gate.

Elder Qin: "I will not accompany you inside. All the spiritual materials needed for setting up the formation are already prepared here. Please come up and let me know when you have finished setting up the formation."

Lin Jingchu nodded in agreement and went straight into the mine.

Following the route he remembered from yesterday, he quickly arrived at the cave that needed to be sealed. Beside the cave entrance, various spiritual materials were piled up.

Talking two ends.

Song Yu rode his jade flute and stopped above the Shen family's spiritual mine.

The former attendant, now the manager of the spirit mine, leaped forward, greeting her with a smile, "Is Fairy Song here again to re-inspect the magic array?"

Her gaze swept over the pale blue protective shield enveloping the entire mine, and she asked, "How is the Six Harmonies Heavenly Formation operating?"

Supervisor: "The magic array is operating smoothly, the spirit stone consumption is balanced, the protective barrier is stable, and there are no hidden dangers."

Song Yu, with gentle eyes and a soft voice, replied, "Yesterday we only examined the Six Harmonies Heaven Formation; the other formations in the mine haven't been thoroughly investigated yet. My junior brother Lin and I will be returning to the sect soon, so we came to check one last time before we leave, just to put our minds at ease."

After saying this, she gracefully descended like a crane and headed straight for the depths of a side path.

Finally, she silently passed through layers of warnings and the Earthly Fiend Formation, disappearing into the darkness of the mine in her white robes.

Several hours passed in the blink of an eye.

Deep within the Qin family's spirit mine, as the last core array tower was firmly in place and activated by embedded spirit stones, the cave entrance that had been constantly gushing gray-black corrosive mist suddenly stopped!

A pale golden spiritual light barrier firmly sealed the corrosive mist inside, its brightness flickering as the mist was emitted.

[Mission Completed: Qin Family Spirit Mine Array Setup]

[Quest Reward: Top-Tier Secret Technique "Great Luo Thousand Illusion Technique"]

Lin Jingchu, who was thirty or forty miles away, moved his mind slightly and directly imprinted a top-level secret technique manual that was obscure and complicated into his mind.

Inside the mine, Lin Jingchu's clone smiled slightly, "Since I'm in a good mood today, I'll throw in a complimentary service for the Qin family!"

As soon as he finished speaking, he activated the mechanism inside the array tower, and each cave began to breathe, drawing in the corrosive mist that permeated the mine tunnels.

Judging by its efficiency, it can absorb all the erosion fog in three days and nights.

"All done!" He clapped his hands, humming an off-key tune, and was about to turn and leave when a faint, strange sound suddenly reached his ears.

"Squeak—squeak—"

A small, monstrous mouse darted out from a side path and suddenly stopped.

The moment their eyes met, Lin Jingchu's expression changed drastically, and he exclaimed in a low voice, "Double-pupiled rats! There are actually double-pupiled rats here that can find rare treasures and blessed lands rich in spiritual energy?"

The two-eyed rat glanced at him and continued darting towards the opposite fork in the road.

Lin Jingchu followed the spirit beast with a look of wild joy on his face, but inwardly he sneered.

Is it finally here? Let me see what your true purpose is.

Lin Jingchu quickly followed, his divine sense locked onto the double-pupiled rat, which was moving fast and slow in the corrosive mist, about a few feet ahead.
