After the destruction of the Immortal Realm, I took in the fallen fairy.

After receiving Lin Heng's affirmative answer, the shrewd demon merchant also put away his smile and kicked the wooden door next to him hard.

"Hey, I told you to get up and cooperate with the young master to form the slave spirit seal, didn't you hear me?"

The fairy, who was squatting on the threshold, trembled.

Only then did her dazed expression gradually return to normal.

Clearly, she was both thirsty and hungry, and her mental state was on the verge of collapse, having reached its limit.

So much so that she didn't react at all when the demon merchant and Lin Heng were negotiating the price right next to her.

Even so, after hearing the demon merchant's words clearly, she could only retort firmly but without any force: "Slave Spirit Seal? No, impossible..."

It's important to know that in the ancient times of immortality, the Slave Spirit Seal was a ritual used by cultivators to form a master-servant contract with spirit beasts.

Even if the spirit beast is unwilling, it will be transformed into a docile and obedient cat or dog after the slave spirit seal takes effect.

But now, someone actually wants to use the Slave Spirit Mark on her...

Instinctively, she wanted to look up and glare.

But a harmless smiling face appeared before her: "My lady, this isn't some ancient immortal era anymore; it's already the 153rd year of the Demonic Calendar. Cooperate a little; it'll be good for both of us."

"Ha, cooperate with you? How could I, a lowly commoner with no ambition, possibly... Ah—!"

Before she could react, she felt her long hair being pulled upwards forcefully.

Even though his limbs were weak, he could only stagger to his feet after Lin Heng.

"You really know these fairies' weaknesses very well."

The demon merchant watched all this with a smile, then handed the fairy's chains to Lin Heng: "Young Master, please bring her to this room to perform the hand seals."

A human and a demon, along with a fairy who was biting her lower lip tightly, came to the next room.

Upon entering the house, the demon merchant eagerly asked Lin Heng, "Young Master, would you like me to fetch some water so you can see her face clearly? My century-old shop never sells inferior celestial slaves."

Lin Heng shook his head: "No need for that trouble, let's start forming the hand seals quickly."

"Young Master is insightful!"

The demon merchant gave a thumbs up, "Immortal slaves are nothing more than tools to nourish spiritual roots. Once the lamp is blown out, even the most beautiful faces look the same."

"..."

Listening to their conversation, the fairy, whose hands and feet were bound, could only quietly glance at them sideways.

After all, she no longer had the strength to even glare.

"Take it."

Lin Heng took out ten spirit stones from his pocket.

"Okay!"

The demon merchant's eyes lit up, and he immediately cupped the spirit stone in his arms.

Since the beginning of the Demon Calendar, there has been no natural spiritual energy in the world, and spirit stones that are imbued with spiritual energy have become the hard currency of the human world.

In the past, people relied on spiritual energy to cultivate immortality.

Now, because small waves of demonic tides invade every now and then, the spiritual energy that counteracts these tides can play a very good role in resisting them.

The demon merchants have always been very shrewd; they know that every demonic tide will be accompanied by the fall of celestial fairies.

If, by using the spiritual energy within the spirit stone, one could pick up a celestial servant during the demonic tide, then a virtuous cycle of making money from wealth could be established…

"Young master, I'll wait at the door. Call me anytime you're ready."

After obtaining the spirit stones, the shrewd demon merchant left the room to Lin Heng and waited outside.

After the door was closed again, Lin Heng didn't waste any more words: "Sit down."

But this fairy was very stubborn, and she just stared at Lin Heng without moving.

"You won't even sit down when I offer you a seat..."

"..."

The fairy was pushed into a chair by Lin Heng and sat down.

Then, Lin Heng walked behind her and lifted the tattered cloth from her back...

"ah--"

As Lin Heng gently tapped her back, the fairy suddenly raised her head, opened her eyes wide, and let out a miserable scream.

Almost simultaneously, a red light shone behind her, and the immortal mark in the center of her forehead also lit up.

A burning sensation instantly spread throughout my body.

In just a few seconds, the fairy's pain reached its peak.

She felt as if some force within her was frantically demanding more from her.

Even though all her strength had been drained, the force that demanded more did not diminish but rather increased...

A few seconds later, the light finally disappeared.

The fairy in front of Lin Heng had already slumped down, her head hanging low, staring blankly at the floor.

The Slave Spirit Seal is complete.

Lin Heng's Immortal Slave Handbook also contains this additional information:

[Bound to Immortal Slave: Yun Qinghe, a prodigy with a Wood Spirit Root.]

[Spiritual Root Purity: 70%]

[Realm Level: Late Nascent Soul Stage (Already Declining)]

Loyalty: -100

A loyalty score of -100?

Upon seeing this message, even Lin Heng almost lost his composure.

However, since the Slave Spirit Seal is already complete, loyalty is no longer important.

After all, the purpose of the Slave Spirit Seal is to force the other party to absolute obedience.

In other words, if Yun Qinghe had even the slightest resentment towards Lin Heng, the slave spirit mark on her lower back would cause her unbearable pain.

Even if she doesn't express it, but only has a thought in her mind, the Slave Spirit Seal will still take effect immediately.

Even because of the existence of the Slave Spirit Seal, Yun Qinghe had to obtain Lin Heng's consent before she could even die.

This is absolute obedience...

However, what truly interested Lin Heng was the information that followed:

[Celestial Servant Title: Golden Jade Fairy]

She was once the personal disciple of the sect leader of a famous sect in the immortal realm, enjoying the resources of the entire sect...

[Title Talent: Automatically replenishes the spiritual energy of the slave master's crystals.]

Good guy!

Lin Heng's eyes lit up.

This fairy is actually a rich woman? She even has an economic skill that can automatically generate spirit stones!

With enough spirit stones, he didn't even have to worry about the demonic tide that might appear at any time, unlike ordinary people.

But when he continued reading...

[A new title will be unlocked for every 50 points of loyalty gained by the celestial servant. The amount of spiritual energy replenished increases with loyalty; currently, the daily replenishment limit is 0.]

It's 0!

Lin Heng almost fainted.

On the bright side, at least the negative 100 loyalty level didn't cause the replenished spiritual energy to become negative as well.

How do you raise a loyalty rating of -100 to 50?

Since she has already become his fairy slave, he can deal with it another day.

……

After confirming all the information in the Immortal Slave Manual, Lin Heng came to Yun Qinghe's side.

She kept her head down, a few strands of hair hanging down with the dust and dirt, her eyes, which were covered, just staring blankly at the floor.

Her chest, still slightly heaving, proved she wasn't dead, but she was practically as good as dead.

It's likely that when the slave spirit seal was formed, her -100 loyalty level caused her to subconsciously resist.

But this resistance actually activated the newly formed slave spirit seal!

Seeing that she was unable to move and even seemed somewhat delirious, Lin Heng had no choice but to personally remove all the shackles from her hands and feet.

"Get up, let's go."

Lin Heng threw the iron chain aside.

"Walk……"

Yun Qinghe slowly raised her head, her eyes blank as she looked at Lin Heng.

"Come home with me."

"Who wants to be with you... Ah—!"

Yun Qinghe let out a scream, and her body, which had just sat up straight, collapsed to the ground in an instant.

Lin Heng said calmly, "You've become my immortal slave now. If you don't want to die, behave yourself."

"..."

With trembling hands, Yun Qinghe scrambled to her feet, too exhausted to utter another word.

She could only quietly follow behind Lin Heng to the door.

"Young Master, is the hand seal complete?"

As soon as the door opened, the demon merchant greeted him with a beaming smile, continuing his sales pitch to Lin Heng, "Would you like to take a look at some other immortal slaves? They're all high-quality goods from those major sects. Buying another immortal slave will add a bit more excitement..."

"You don't need those in your yard."

Lin Heng had already confirmed that those fairies simply could not meet the conditions of the Immortal Slave Manual.

However, seeing that this demon merchant was more reliable than the individual merchants on the street, Lin Heng took out another spirit stone and placed it in his hand: "If you have any new immortal slaves, remember to notify me immediately."

A glint of shrewdness flashed in the demon merchant's eyes, and he quickly flattered, "Thank you, young master! Young master's spiritual root is eighteen!"

"..."

"By the way, may I ask where you live, young master? I'll personally inform you when the goods arrive!"

The demon merchant felt that he had definitely met a young master from a prestigious family today.

Using spirit stones to buy information is an extravagant act!

Lin Heng pointed in the direction of the market exit: "Keep going south, the first house is my home."

After saying that, Lin Heng led Yun Qinghe away in the direction he had indicated.

"Go south... south?!"

At this moment, the demon merchant, who was still standing at the gate of the courtyard, was stunned.

South? Isn't that the slums on the outskirts of Linxian City?

How could the poor in the slums, who struggle to make ends meet, afford to enjoy the luxuries of the immortals?

But Lin Heng actually did walk in that direction.

And behind him followed a barefoot fairy servant, whose body was covered only by tattered cloths...
