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

"it!"

Without even thinking, Tian Qianchen pointed directly at the Spirit Suppressing Tower Formation.

The fervor in his eyes for the knowledge of array construction almost surpassed his loyalty to the Tian Shu Kingdom...

"Actually... I've studied the Spirit Suppressing Tower Formation before."

Tian Qianchen rubbed his hands together sheepishly and said, "But I seem to have made a slight mistake in understanding the arrangement of the rules. If you could guide me... the 'Lin' in 'Linxian City' is the same as the 'Lin' in 'Lin Heng'!"

Lin Heng smiled and said, "Isn't that a bit inappropriate, Elder Tian? I remember that kings and nobles who possess legitimate territory all have a relevant document from the General Administration Office?"

"Hmph, isn't that simple?"

Tian Qianchen clapped his hands, then simply said three words: "Pen, paper, ink!"

Lin Heng winked at Yun Qinghe beside him, and she obediently went back into the house to get her things.

Soon, the items were handed over to Tian Qianchen.

He also wrote a lengthy imperial edict on the paper regarding the ownership of Linxian City...

"You've come to the right place at the right time. Over the years, I've written the most imperial edicts concerning the granting of territories in the General Administration."

With that, Tian Qianchen simply handed the imperial edict to Lin Heng.

At the same time, his gaze towards Lin Heng became intense again: "Then now..."

"bring it on."

Lin Heng didn't try to fool Tian Qianchen. He squatted down behind him and began to explain the rules and arrangements of the Spirit Suppressing Tower Formation.

However, the array construction knowledge he explained to Tian Qianchen was different from the array construction knowledge he used himself.

If the Spirit Suppressing Tower array is constructed according to the array construction knowledge he is now explaining, it can directly launch a defensive attack with the power of the Spirit Realm without the injection of immortal techniques.

However, its power is clearly much weaker than the Spirit Suppression Tower Formation in the slums.

The array formation unlocked by the Immortal Slave Manual is different from the array formations that were previously passed down in the Immortal Ancient Era.

For example, his Resurrection Array.

When Yun Qinghe first saw the Spirit Restoration Array he constructed, it had a completely different function from the Spirit Restoration Array of the Yunling Sect.

Therefore, strictly speaking, the array formations passed down in the Immortal Ancient Era are a weakened version provided by the Immortal Slave Manual.

To Lin Heng's surprise, even though he shared his knowledge of array construction, the explanation did not go smoothly...

Why is it arranged this way?

"Shouldn't they be connected?"

"Isn't the arrangement of these stone bricks a bit too hasty?"

Tian Qianchen kept asking basic questions, which finally made Lin Heng question, "Elder Tian, ​​are you really at the level of an intermediate array constructor?"

"Well……"

Tian Qianchen rubbed his hands awkwardly and said, "That's what my own subordinates say, although those four old guys all said I'm at most a beginner array constructor..."

"..."

Is it really from an agency?

At best, he can only be considered a framing enthusiast...

But since it was a collaboration with the General Administration, Lin Heng kept his promise and completed the explanation.

Because he knew very well how much the developing slums needed this kind of official endorsement.

Although it was already late at night, he still wrote a whole notebook for Tian Qianchen.

"Take some time to thoroughly study these basic rules before trying them out..."

"Okay, okay, I'll stay up all night tonight!"

Facing Lin Heng, who was explaining the knowledge of array formation to him, Elder Tian Qianchen of the General Administration Division was already as respectful as a student.

"Alright, I need to rest, you too..."

Lin Heng rubbed his temples wearily, but suddenly realized something.

This old guy suddenly popped up from underground, where will he stay tonight?

"Why don't you try to squeeze in with the demon merchants at the border?" Lin Heng asked tentatively.

"No problem! I'll be right there."

As a result, Tian Qianchen not only did not find it objectionable, but also agreed very readily.

After all, in his mind, Lin Heng's willingness to let him stay meant that he would have more opportunities to learn about array construction in the future...

"Oh, right."

Suddenly, Lin Heng realized a crucial issue.

"What? Is there any knowledge you've missed?"

Tian Qianchen immediately handed over the notebook and pen.

"That's not it."

Lin Heng shook his head and asked Tian Qianchen, "Since you said the General Administration Division is also researching array construction, but many arrays require spiritual energy as a driving force, how do you manage to do it? Is it entirely based on the spiritual energy in spirit stones?"

For example, the Spirit Restoration Array cannot be operated using spiritual energy.

Lin Heng's method, however, uses Yun Qinghe's wood spirit root as a medium.

"Well... forgive my bluntness, but I really can't tell you."

Tian Qianchen bowed apologetically to Lin Heng, "After all, if this news gets out, it could very well cause a stir throughout the entire Tian Shu Kingdom..."

But after a pause, he seemed to think that it might not be right to keep it a secret from Lin Heng, who had taught him all night.

In addition, Lin Heng's own array-building skills made him feel that he far surpassed those old guys in the General Administration Division.

Even if he didn't say it, he could probably guess...

"never mind!"

So Tian Qianchen gritted her teeth and said, "I'll give you a subtle hint."

"The reason our General Administration Division studies array formations is because we discovered that the spiritual energy of this world has not completely disappeared. And the key point... lies in the immortal slaves who have fallen into the mortal realm."

After saying that, Tian Qianchen looked up at the sky and said, "Hmm... It's good that a celestial slave has fallen to the mortal world! Back when I was young, I even brought back a fox spirit from the Western Regions. Its tail was so bristling... tsk tsk!"

With his hands behind his back, he slowly walked towards the residential area near the demon merchant's residence...

It seems that there are still secrets hidden from the world within the General Administration Office?

Lin Heng narrowed his eyes slightly, watching Tian Qianchen's figure gradually disappear into the distance.

After a short stay, they returned to their own courtyard.

"Master, shall we go to the Immortal Spring?"

As soon as she entered the room, Yun Qinghe took the initiative to ask.

Mu Tinglan, who was reading a book, also looked up and looked at Lin Heng.

Song Jingyu snorted and pretended not to hear...

"etc……"

Lin Heng walked over and came to Mu Tinglan's side.

Mu Tinglan gently placed the book aside and asked in a low voice, "Master, do you want the nourishment of the water spirit root?"

Lin Heng shook his head, simply gazing at the ample bosom subtly concealed by the purple robes—the location indicated in the Immortal Slave Manual.

[The Nine Seas Goddess's Platform for Resolving Delusion: Unlock progress 2%, unlock attempts: 1.]

[Available Unlocks: 1. Increases the loyalty of the Goddess of the Vulture to 300. 2. Displays the next Celestial Slave title.]

【use or not? 】

Last time, the effects of the title "Goddess of the Vulture" were only partially revealed.

So this time, Lin Heng decided to fully understand the role of Yun Qinghe's title.

Yes! Choose option 1!

[Goddess of Manluo (After unlocking the Goddess title, the next title requires a maximum loyalty of 300 and unlocking a powerful Goddess Array for the slave master.): Goddess of Manluo Statue, granting the celestial slave with the Goddess of Manluo title true access to the goddess's divinity.]

[Construction requirements for the Manluo Goddess statue: The celestial servant must achieve 100% spiritual root purity, the Thousand Branches Vine Sword must be unlocked in all five stages, and the servant must complete joint cultivation with the servant master to establish a connection between the Five Sources Immortal Venerable and the Manluo Goddess.]

Wait, no...

Why are there more unlock conditions than the description of its function?

Lin Heng couldn't help but mutter a complaint to himself.

However, he also knew.

The mere description of obtaining true divinity carries immense weight!

This is probably the ultimate form that a Celestial Slave can be cultivated to using the Celestial Slave Manual...

But clearly, this is not an area he can currently get involved in.

Spend half of the unlock attempts to fully reveal its effects, just like taking a peek into the future.

Since it only costs half a unlock point, he still has one more chance to unlock:

[Fairy Maiden's Effect: 1 unlock attempt remaining.]

Lin Heng glanced at the three fairy servants in the room, and finally focused his gaze on Song Jingyu, who currently had the lowest loyalty and had also seen the greatest improvement.

【Yanxi the Heavenly Maiden of Illusion: A fire spirit fairy who is proficient in the rules of Origin Fire, capable of covering her eyes with flames to see through truth and falsehood and the future...】

[Obtaining the title of "Flaming Dawn Celestial Maiden" unlocks the array: Demon-Seeking Platform.]

[The Demon-Seeking Platform: Possessing the eyes of the Radiant Dawn Celestial Maiden, it can accurately predict the timing and level of the approaching demonic tide.]

Predicting the Demon Tide?

Lin Heng's eyes lit up.

In the current Magic Calendar, isn't this array a bit too practical?

Lin Heng then turned his attention to Song Jingyu, whose loyalty was only 28.

He walked over and patted the red, spiky hair on Song Jingyu's head.

"What are you doing?"

Song Jingyu trembled, her hands nervously gripping the hem of her brocade robe.

Lin Heng said calmly, "Tonight, you'll come with me to soak in the Immortal Spring alone."

"Huh?!"
