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

One transformation of the Azure Tortoise caused Mu Tinglan's strength to degenerate to a level inferior to that of an ordinary mortal immortal.

In the past, she would have been frustrated by her inability to help her master.

However, she now knows that her help to her master has never been limited to her own strength.

"I'm so sorry, Master."

Turning her head, though her words were an apology, she smiled lightly at Lin Heng: "For a long time to come, I probably won't be of much help in the battles at my current level. But I will definitely help you in other ways, such as reading books on the Answering Platform, and when you need the nourishment of the water spirit root..."

"There's no need to worry about your cultivation level."

Lin Heng shook his head and said, "After we get back, I will plant some spiritual herbs for you to help you recover."

Mu Tinglan nodded with a smile at the corners of her eyes: "Yes, thank you, Master..."

Just then, the black fog that had filled the sky began to gradually dissipate.

Everyone looked up.

Gesang Nazha said calmly, "It seems we've successfully weathered this demonic tide..."

"However, I haven't finished what I need to do yet."

Suddenly, Lin Heng, who was supporting his arm, gently tapped his chin with his hand.

Everyone around him looked at him.

"Is there anything else you need to do, Master?" Yun Qinghe asked, puzzled.

Lin Heng pondered for a moment and said, "Shen Zu is already dead, so this place... seems to be lacking in dedicated personnel."

"I understand, Master."

Before Lin Heng could finish speaking, Mu Tinglan already understood his meaning.

"Junior sister, give me a spirit stone."

She walked up to Yun Qinghe.

"Oh, here you go, senior sister."

Yun Qinghe took out a spirit stone from her bosom and placed it in her palm.

Mu Tinglan nodded, then held the Mermaid's Tear Tide-Calling Flute in one hand, stood in the center of the pit, and raised her eyes.

She took a deep breath and placed the azure flute next to her delicate, thin lips.

As a night breeze lifted her purple sleeves, a melodious flute tune began to play.

"This, this is..."

The immortal servants around Lin Heng all looked down at their own injuries.

The injured area healed rapidly as this piece of music played.

They can't even feel pain.

As the healing melody resounded throughout the entire Xuanji Mine, some of the fairies who had been lying unconscious on the ground, barely clinging to life, gradually opened their eyes, raised their heads, and then propped themselves up to stand up.

The melodious tune, through its gentle nourishment of their spiritual roots, reawakened their vitality.

And they were the immortal maidens that Mu Tinglan had previously discovered with her men; they had not yet been bound by the slave spirit seal, and their spiritual roots were still intact.

Lin Heng knew.

This is the third stage ability of the Mermaid's Tear Tide-Summoning Flute, the Azure Tide Healing Melody, which has powerful healing effects.

"Goddess, fairy! Goddess, fairy is here!"

Soon, the fairies whose lives had been reawakened knelt around Mu Tinglan, bowing and kowtowing: "Goddess Fairy, thank you for saving our lives!"

As the flute music of the Azure Healing Melody ended, the spirit stone in Mu Tinglan's hand turned into a dull, ordinary crystal.

"You're welcome."

She shook her head at the fairies around her, then looked at Lin Heng beside her: "He is my master, he saved you."

"Thank you, young master! Thank you, young master!"

The twenty or so fairies turned to face Lin Heng and kowtowed to him.

Mu Tinglan also came over and whispered to Lin Heng, "Master, the spiritual roots of the other fairies and cultivators have all been destroyed by Shen Zu. Even the Bilan Healing Spirit Melody can only save them."

As she finished speaking, Mu Tinglan was also thinking to herself: the only benefit of saving them is that, if the master has a cleanliness obsession, they, who have not yet formed the slave spirit seal, would naturally meet the master's requirements.

The downside is that they might not meet the owner's need for professional help...

"That's enough."

Lin Heng nodded and calmly said to the fairies around him, "Saving you all means I need your help."

"what?"

For a moment, all the fairies were stunned.

To work for this young master?

Subconsciously, they thought of the mine owner of Xuanji Mine.

Those fairies who swallow mineral water and absorb toxins are also doing him a favor...

"But there's a problem."

Suddenly, Lin Heng glanced at the fairies suspiciously: "Do you even know how to mine?"

"Dig, mine?"

The fairies looked at each other in bewilderment.

This was the first time they had ever heard such a request before, even after being brought to the mine.

"Mining...wait, what?"

Suddenly, one of the water spirit fairy's children seemed to understand something.

Although this young master's request was somewhat strange, it was still better than making them absorb poison and spiritual moss...

Her face flushed, she said to Lin Heng, "Young Master, we water-elemental fairies... are quite skilled at mining!"

"You water-elemental fairies are also good at this?"

Turning his head, Lin Heng looked at Mu Tinglan with some confusion.

"I...I don't know either."

Mu Tinglan shook her head.

"never mind……"

Lin Heng waved his hand and continued speaking to the fairies, "Since you say you are good at mining, then pick up your pickaxes and teach the other fire-elemental fairies a thing or two."

The water spirit fairy was taken aback: "Do we still need a pickaxe?"

Lin Heng asked suspiciously, "What do you use to mine if you don't use a pickaxe...?!"

He seemed to understand what the water spirit fairy meant by mining halfway through his sentence.

Not only him, but Mu Tinglan next to him also turned her head away, a blush appearing on her face.

After all, she had actually done mining, as the water spirit fairy had mentioned.

And at that moment, all I could think about was my owner beside me...

Realizing that his words had caused a misunderstanding among these water-spirited fairies, Lin Heng had no choice but to explain helplessly, "What I meant by mining is that you extract the ore from here."

"We can do that!"

In an instant, the fairies kneeling on the ground also nodded in agreement.

One of the fairies explained to Lin Heng, "Young master, we've been here for a long time. Even if we didn't know how before, we learned by watching the miners work!"

"That's good."

Lin Heng breathed a sigh of relief: "However, the prerequisite is that I need to form a slave spirit seal for you. Otherwise, I will not feel comfortable letting you use the magic array set up here."

"Wait, young master, you said you'd teach us how to use the magic array here?"

The fairies stared at Lin Heng in disbelief.

With Shen Zugang gone, the mine is now without an owner, and anyone wanting to take it over will naturally need certain defensive measures.

"Hmm, but these magic arrays are too basic. I'll set up some more advanced arrays later."

Lin Heng nodded and continued, "And to mine for me, you'll naturally need to become my celestial slaves. As for the work arrangement... you'll mine for four hours a day, with normal rest in the morning and evening, and half an hour of rest after meals. The rest of the time you can arrange your own time at the mine."

"..."

One sentence silenced the fairies kneeling on the ground.

They mine for four hours every day.

Serving the master is the duty of a slave.

But what does it mean to arrange the rest of the time arbitrarily?

Even the new rules of Dawn that appealed to them never mentioned the word "casual".

In an instant, a bold guess formed in their minds.

One of the bolder fire-elemental fairies even trembled as she blurted out, "Young master, what you mean by 'arranging things as you please' is... freedom?"

Lin Heng nodded: "Yes, as long as you finish the work, you can do whatever you want, and I will give you spirit stones, which you can use as you please."

"!!!"

In an instant, almost all the fairies turned their backs and lifted the backs of their clothes.

Lin Heng's eyes widened.

What's going on?

Has the once bustling city of Jinlu fallen to such a state of moral decay?

The next moment, the fairies cried out impatiently, "Young Master... no, Master, please form the Slave Spirit Seal for us!"
