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

With the end of this demonic tide, Lin Heng completed the process of imprinting slave spirit seals on all the fairies in the mine.

But even if he didn't steal this mysterious mine himself, he still illegally occupied it during the demonic tide.

If Mi Yuanzheng of the City Lord's Mansion wants to take this seriously, there will inevitably be another round of trouble.

Therefore, when establishing the slave spirit seal, Lin Heng only allowed Mu Tinglan and Gesang Nazha to stay behind.

The rest of you should return to the Cloud Oasis first. Those who need to replenish their spiritual energy should do so, and those who need to rest should rest. They will return to take over the shift at dawn...

As for why Mu Tinglan and Gesang Nazha were left behind, it was because Gesang Nazha possessed the strength of the Enlightenment Realm. Even without spiritual power as support, she could still accurately perceive the power of the rules.

Although Mu Tinglan has fallen to the Qi Refining Realm, her Mermaid Tear Tide-Summoning Flute can still exert some of its powerful effects.

For example, in the first stage, the ability to double the power of immortal techniques and secret arts can be used on the Extinction Fire Pearl in Lin Heng's palm's Mind Pattern.

If any unexpected event occurs, it can also be used in conjunction with the mine's magic array to protect itself.

The demonic tide has ended; he doesn't believe any threat can withstand the full force of two Nascent Soul cultivators...

Before long, as Lin Heng completed the slave spirit seals one after another, he had twenty-seven immortal slaves in the mine.

However, there are still many things to do tonight.

For example, assigning them specific mines to manage and explaining to them how to use the magic arrays within the mine.

After all, he couldn't stay in the mine every day, nor could he set up the array he was proficient in in a short time.

In case they encounter any danger, these magic arrays can also help them protect themselves.

Gradually, the sky over Jinlu City began to lighten slightly.

Lin Heng, who had been busy all night, couldn't help but stretch.

Fortunately, since the end of the demonic tide, the entire Xuanji Mine has been at peace for the time being.

At this moment, Mu Tinglan walked over and said softly, "Master, you should actually ask your junior sister to stay; she could help you relax."

She now seems to have gained a power since last night.

However, this ability is very special. It has nothing to do with the level of cultivation or strength, but mainly with its master.

It seems she can now understand her master's needs better than before, and naturally considers her master's needs wholeheartedly...

"She's already here."

Lin Heng looked toward the entrance to the mine.

"Um?"

Mu Tinglan looked up and saw Yun Qinghe coming from the center of Jinlu City, accompanied by two fire spirit root immortal slaves who had recovered their strength in the Blazing Fire Camp.

However, at this moment, Yun Qinghe's expression was extremely cold.

Because standing next to her was a familiar-looking demon.

Mu Tinglan remembered that this demon was the old demon merchant who lived on the Oasis in the Clouds and was originally a seller for Yun Qinghe.

If this old demon merchant hadn't also been working for their master, Mu Tinglan would have had no doubt that, given her junior sister's personality, she would have used her recovered spiritual power to kill him...

"Master, this demon merchant says he has something important to report to you in person."

When Yun Qinghe reached Lin Heng, she also brought the old demon merchant over.

"Yes, go ahead and speak. There are no outsiders here."

Lin Hengchao nodded to the old man, the venerable merchant who had been a slave for centuries.

At this moment, Mu Tinglan also pulled Yun Qinghe aside.

"Junior sister, actually... I don't think you need to hate him too much."

Mu Tinglan glanced at the old demon merchant standing in front of their master.

Yun Qinghe frowned slightly: "Senior sister, but back on Mount Linxian, it was he who put me in shackles and then took me to the market in Linxian City..."

"But isn't he now working diligently for his master?" Mu Tinglan smiled.

"Of course I know that."

Yun Qinghe snorted coldly, "If it weren't for the fact that Master kept him around for his own good, I would have already used the Thousand Branches Vine Sword..."

"Junior sister, you still don't understand."

Mu Tinglan smiled and shook her head, interrupting.

"Hmm?" Yun Qinghe looked at her senior sister in confusion.

Mu Tinglan winked at her: "If it weren't for this demon merchant, would you have met your master?"

"Eh?"

Yun Qinghe paused for a moment, then lowered her head and fell into deep thought.

That sounds kind of reasonable...

Mu Tinglan patted her shoulder: "It's not that we have to get along, but at least don't be too hostile. Just treat her as... a fellow disciple from the same sect, but someone whose temper you don't get along with."

Yun Qinghe took a deep breath: "Yes, Senior Sister, I understand."

Mu Tinglan nodded slightly, glancing at Lin Heng out of the corner of her eye.

After all, their master probably wouldn't want to see any potential infighting among those who work for him...

At the same time, the old demon merchant brought by Yun Qinghe hurriedly said after seeing Lin Heng, "Young Master, actually, it wasn't mainly me who came to find you this time."

"Didn't you call for me?"

Lin Heng was surprised.

The old demon merchant explained, "I got up early this morning intending to find a fairy slave for you in Golden Deer City... but when I passed the inn east of Dawn Square, Elder Tian from the General Administration Department stopped me."

"The old man called you over? He wants you to deliver a message?"

"That's right, young master."

The old demon merchant nodded repeatedly and said, "Elder Tian said that when the demon tide occurred last night, the General Administration sent him an urgent message overnight, forcing him to leave for a while."

Did the General Headquarters order Tian Qianchen to return?

"Young Master, before Elder Tian left, he asked me to leave you this letter, telling me not to open it under any circumstances, but to give it to you so that you can unravel the spiritual energy on it yourself."

As he spoke, the old demon merchant also took out a piece of paper sealed by the spiritual energy of the spirit stone from his pocket, which was covered with a layer of obvious golden light.

No one can see the contents of this letter before absorbing its spiritual energy.

Lin Heng knew that the old man must have written something important in the letter.

So after he took the letter, he had one of Yun Qinghe's fire-elemental immortal servants absorb the spiritual energy from it.

As the golden sheen on the surface of the letter disappeared, the text on it became visible:

"Damn it, little teacher, those idiot elders from the General Administration sent someone to call me back..."

Upon seeing this first line, Lin Heng's eyelids twitched involuntarily.

He didn't even need to examine the handwriting closely; based on the highly refined tone of the voice, he could tell that it was indeed the old man's own handwriting.

Although he really wanted to complain, Tian Qianchen's identity seemed to be that of the foolish elder he himself had described...

But Lin Heng also knew that the letter the person had left behind was definitely not just a few curse words to vent their dissatisfaction:

"They called me back mainly for two reasons."

"Firstly, the demonic tide that occurred last night caused an anomaly in the tomb of the Five Source Immortals. As an elder, I need to go back and organize research."

"Secondly..."

In this spot, Lin Heng clearly shows very heavy ink marks.

It's estimated that Tian Qianchen considered this for a long time before writing it.

Looking further ahead, it seems that Tian Qianchen made a very big decision at that time:

"Alright, little teacher! You've taught me so much about array construction, and even left me a way out in the Cloud Oasis. And the biggest secret of this capital city... I'll tell you too!"

"In fact, the granddaughter of the King of Tian Shu Kingdom, who is also a princess with a fiefdom on the southern border, was once an immortal who attained enlightenment."

"But after entering the Demon Calendar, the princess fell from the Immortal Realm and has been in a coma ever since. The King has been using special methods to maintain her life force."

"It is said that during last night's demonic surge, the princess seemed to show signs of awakening, so the king ordered the elders of our General Administration to rush over immediately to check on her..."
