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

Boom boom boom!

A noise came from the other side of the wall.

Xia Feng, who was next door, frantically pounded on the wall and shouted, "Young Master Lin! Did you hear the bells of Linxian City?"

"I heard you, what's going on?"

"I forgot to tell you before, once the bells of Linxian City ring... it means a demonic tide will sweep in that night!"

"Damn it, the demonic tide has come early... Anyway, good luck, Young Master Lin. I have to get back to building the wall myself now."

After saying that, Xia Feng continued cursing at his servant, "You bitch, hurry up! If you don't finish building the wall by tonight, I'll finish you off before I'm done for!"

"..."

"Owner……"

Having witnessed the power of the demonic tide, Yun Qinghe couldn't help but ask Lin Heng, "Do we need to build a wall too?"

"Need not."

Lin Heng glanced at the Immortal Slave Manual and said casually, "I have my own rhythm."

……

Upon learning that the demonic tide was about to strike, Yun Qinghe, who had just been enjoying her meal, frowned deeply.

After dinner, it gradually got dark outside.

"It seems the demonic tide is really coming..."

Looking out the window, Yun Qinghe gently bit her lower lip.

After all, it was still far from dark, and the early arrival of night was a sign of the approaching demonic tide.

Subconsciously, she looked at her master, Lin Heng.

The demonic tide is something even cultivators struggle to withstand, so how could he...?

Yun Qinghe stared blankly at Lin Heng, who was pacing back and forth in the room.

He was so confident just now, saying he had a solution, but judging from his current reaction, it doesn't seem like he has one.

"First, construct a spirit-restoring array to generate spiritual energy, then construct a demon-repelling array to conceal ourselves amidst the demonic tide..."

This was Lin Heng's line of thinking, and he felt that there was nothing wrong with his idea.

Why does the Immortal Slave Manual keep saying that this target cannot be constructed at this location for the Spirit Restoration Array?

Suddenly, Lin Heng noticed Yun Qinghe looking at him...

Yup!

She used to be a fairy. The Spirit Restoration Array and such are all celestial formations, so why not just ask her directly?

"Do you know where the spirit restoration array should be built?"

"A spirit restoration array?"

Upon hearing this familiar yet unfamiliar name, Yun Qinghe was momentarily stunned.

After all, there was no spiritual energy left in the world after the invasion of the demonic tide. Although the Spirit Restoration Array is a formation that can gather spiritual energy, its principle still relies on the natural spiritual energy in the world.

"Generally speaking, spirit restoration arrays are built in the places where immortal disciples usually rest."

That's right!

Lin Heng couldn't help but touch his chin. This is my house, so why can't I set up an array here?

Yun Qinghe continued, "The advantage of this construction is that it allows the Spirit Restoration Array to collect residual spiritual energy from the surrounding area while the immortal disciples are resting, and it also provides spiritual energy replenishment for the immortal disciples even when they are sleeping..."

Upon hearing this, Lin Heng immediately turned his gaze to his bed.

It was called a bed, but it was really just a large mound of earth covered with a layer of weeds...

[The conditions for constructing the Spirit Restoration Array are met. Shall we proceed with the array construction?]

That's right! It's in bed!

Following the instructions in the Immortal Slave Manual, Lin Heng quickly went to the bedside.

Yun Qinghe looked at him blankly, only to see Lin Heng bring back a few bricks from outside and place them in front of the bed...

and many more!

Suddenly, Yun Qinghe opened her eyes wide in surprise.

Although the bricks looked broken and dilapidated, Lin Heng arranged them into a shape that was both familiar and unfamiliar to Yun Qinghe!

Thinking back to the spirit restoration array that Lin Heng had asked about earlier...

That's right, this is how the Spirit Restoration Array is constructed!

But what made Yun Qinghe feel unfamiliar was that she had never seen such a small array before.

In the immortal realm, her sect naturally also had a spirit-restoring array.

The area occupied by the Restored Spirit Array is even larger than the slums here!

Of course, the bigger the array a builder constructs, the better. On the contrary, the higher the builder's skill level, the more complex the array they can construct in a small space.

So her master was actually an excellent array builder?

"alright."

After working for a while, Lin Heng stood up and looked at the completed Spirit Restoration Array with satisfaction.

However, Yun Qinghe frowned.

Indeed, the slave master she constructed was a spirit restoration array.

Although the Spirit Restoration Array is a low-level array, Lin Heng's array construction level is definitely not low, given that he was able to successfully construct it in such a small space!

The problem is...

"Owner."

After discovering that Lin Heng was very likely a highly skilled array builder, Yun Qinghe became much more adept at calling him "master."

However, she said with concern, "This Spirit Restoration Array requires natural spiritual energy as a foundation to activate..."

"Need not."

Lin Heng shook his head and pointed to the bed, saying, "You go up there."

Yun Qinghe's body trembled instantly.

She couldn't help but think of another use for the Spirit Restoration Array.

In the immortal realm, the main function of the Spirit Restoration Array is to gather spiritual energy for cultivation.

However, in the human realm, especially among wealthy families, women are often brought into the spirit restoration array.

Nourished by spiritual energy, they can experience a sensation in women that is very similar to that of fairies.

Unfortunately, as a fairy servant, she had already lost the fairy's spiritual energy.

So Lin Heng told her to go to bed now...

"There's no time."

At this moment, Lin Heng looked at the sky outside and frowned.

"what!"

Yun Qinghe, who remained standing still, triggered the effect of the Slave Spirit Seal once again.

The force that forced her to submit caused her to fall to the ground.

He collapsed onto the bed that had been constructed as a spirit-restoring array.

"This, this is..."

Suddenly, Yun Qinghe, lying on the bed, opened her eyes wide in disbelief.

Although she had lost her spiritual power, she could clearly feel that at the moment she fell onto the bed, the Spirit Restoration Array and the area around her were filled with the flow of spiritual energy!

Although this spiritual energy is very thin, it is absolutely impossible for it to occur in the year 153 of the Demon Calendar!

Subconsciously, Yun Qinghe looked at Lin Heng.

Lin Heng calmly said, "As long as you stay in bed, the Spirit Restoration Array can generate spiritual energy using your wood spirit root. That's the only prerequisite. If you want to survive today's demonic tide, you'd better stay still and not move around."

"Yes...yes, Master."

Yun Qinghe nodded somewhat blankly.

To be honest, this was the first time she had ever seen a spirit restoration array activate like this.

Lin Heng's idea of ​​relying on the spiritual energy produced by the Spirit Restoration Array to survive the demonic tide was, in Yun Qinghe's view, very difficult to achieve.

Although the Spirit Restoration Array has indeed begun to generate spiritual energy, this spiritual energy is too thin, not even comparable to half a spirit stone. How can it resist the invasion of the demonic tide?

However, she didn't say anything more this time.

Because her master had taken some bricks to the doorway, seemingly constructing a new formation...

Whoosh!

Almost the instant Lin Heng completed the Demon-Sealing Array, the silent night sky seemed to open its scarlet eyes.

Lin Heng, who had just stood up at the door, saw a thick, dark fog descending from the sky.

In the slums, wriggling worms began to devour the surrounding withered trees and even the walls.

But Lin Heng's home was like a deserted island in the ocean, completely ignored by the vast swarm of demonic insects...

"Perfect."

Lin Heng looked down at the activated demon-concealing array and knew that he would definitely be able to safely weather tonight's demonic tide.

"Go to sleep."

Turning around, Lin Heng stretched wearily.

But the next moment, he stared blankly at the scene before him.

Yun Qinghe, who had fallen from a fairy to a celestial slave, had actually closed her eyes and curled up her long legs, asleep on his bed...
