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

However, judging from the rules given in the Immortal Slave Manual, constructing the array in the Cloud Oasis is definitely a huge project.

Besides requiring a large number of spirit stones, a large plot of land is also needed. Most importantly, the place where the array is set up must be underground in the territory.

Fortunately, beneath the Zhang family's ancestral graves lies a passage leading to the city lord's mansion's underground chamber...

After Lin Heng had someone clean up the entrance to the passage, he decided to take Song Jingyu down to take a look first.

After all, she used to live in this cave, so she's definitely more familiar with the environment inside than I am.

"Hey, hey, Young Master Lin!"

Just as they reached the cave entrance, Xia Feng arrived.

"Young Master Lin, are you... going downstairs?"

Xia Feng pointed to the passageway to Old Zhang's house.

"Okay, let's go down and take a look."

"That's true! With so many celestial slaves now, you must really need the 'strength-enhancing grass' from there!"

Xia Feng nodded, but said with some worry, "But Young Master Lin, don't forget, there might be demons inside..."

"The monster you're talking about is her."

Lin Heng patted Song Jingyu's red, upturned hair next to him.

"Me? A monster?"

Song Jingyu blinked, puzzled.

"what?"

Xia Feng was also taken aback.

This little fairy servant... doesn't look like a demon at all!

Lin Heng shrugged and said, "In short, there are no more of the monsters you mentioned down there, and I'm not going there to collect essence herbs."

"Not picking the strongest, most vigorous plants?!"

Suddenly, Xia Feng's eyes lit up: "Those spirit herbs..."

"Do you really need it?"

Lin Heng looked at his kind neighbor with a smile.

The reason he allowed Xia Feng to stay in his territory was that he saw through Xia Feng and realized that Xia Feng was a very pure person.

This guy wears his heart on his sleeve, no matter what he's thinking.

"hey-hey."

Xia Feng rubbed his hands together slyly and said, "Didn't I give my fairy servant a little bit of status at home a while ago?"

Lin Heng nodded.

He remembered that Xia Feng had specially brought back this fairy slave in a small cart back then...

"The result was just as good! Young Master Lin, your method really works!"

Xia Feng gave Lin Heng a thumbs up.

"Does it work?"

Lin Heng looked at Xia Feng with suspicion.

At that time, Xia Feng said he wanted to treat the immortal slaves well, guessing that Yun Qinghe and Mu Tinglan used immortal energy because they had gained respect from Lin Heng and then unleashed their potential...

But Lin Heng knew very well that Yun Qinghe and Mu Tinglan were able to use immortal techniques entirely because of the effect of the Immortal Spirit Spring.

But looking at Xia Feng's expression now...

Could it be that his vivid imagination has actually come true?

"Yeah, of course it works! Damn, I never knew immortal slaves could do this..."

Xia Feng, rubbing his aching lower back, said, "I not only served tea and water to my fairy servant, but I also bought her silk clothes from the Sand Fox family. Today, I had her change into that silk, and then step on my spiritual root... the feeling... I even thought I could become an immortal!"

"..."

"Young Master Lin, don't look at me like that. Let me tell you, that feeling was probably more exciting than becoming an immortal! I even felt my house shake a couple of times..."

That damn old fox has grown bigger!

At this moment, Xia Feng suddenly sighed: "It's a pity, but for the first time I feel that my fire spirit root is a bit powerless... If I don't use the strengthening grass to replenish it, I'm worried that my spirit root will become a fire poker in the future."

Lin Heng finally understood. It turned out that his neighbor wanted to come down with him to pick some strong grass...

"You can go get it yourself. We have other business to attend to downstairs."

"That would be great!"

With Lin Heng's permission, Xia Feng followed him eagerly into the cave.

Perhaps in this magical calendar, blind trust in others is a major taboo.

But in Xia Feng's heart, Lin Heng was even more reliable than his parents...

Just look at the Rock Armored Demon Bear from last time.

Even the Immortal City was completely razed, but he survived thanks to the stone tower built by Lin Heng.

Therefore, Xia Feng knew very well that if his neighbor really wanted him dead, Lin Heng wouldn't even need to lift a finger; he would end up like Old Zhang in the grave above...

Halfway there, Xia Feng saw a large amount of sturdy grass and stopped to pick it.

Lin Heng, led by Song Jingyu, arrived at a deeper part of the cave.

Sure enough, after walking through the passage, they arrived at Song Jingyu's former residence.

"Teacher, actually, this passage was dug out by Xiaohezi back then."

After returning to the cave, Song Jingyu led Lin Heng on a tour of the cave where she had lived for nineteen years: "This cave is very large, but it no longer has the spiritual energy it once had."

"Because my sister's tree baby... is a keepsake that my mother entrusted to me and then gave to my sister."

"Under the protection of the tree babies, this place used to have spiritual energy comparable to that of the celestial realm."

Lin Heng nodded slowly.

After all, he had seen a description of the Thousand Branches Vine Sword in the Immortal Slave Manual.

In the past, the Thousand Branches Vine Sword was a divine weapon used by the Goddess Vine to open up the rules of the immortal realm.

Being able to temporarily preserve some spiritual energy in a world where spiritual energy is depleted is merely one of its insignificant functions.

It should be noted that just a short while ago, Yun Qinghe, who was only at the early stage of the Nascent Soul realm, used the Thousand Branches Vine Sword to bind Bai Ma Meiduo, who was at the Enlightenment realm.

"This place looks pretty good."

After walking around the cave a few times, Lin Heng nodded in satisfaction.

The vast underground space perfectly meets the array construction requirements of the Cloud Oasis!

"Let's go up first."

After the survey was completed, Lin Heng took Song Jingyu back to the ground and then gathered the fairy servants together.

"There's nothing to do today, let's move all the spirit stones from my courtyard down first."

"Yes, Young Master Lin!"

The celestial servants all began to work.

Just then, another servant rushed over: "Young Master Lin, we've finished building the house!"

"Is the house finished?"

Lin Heng's eyes lit up. "You guys move the spirit stones over first... Oh, and leave all the fire spirit roots behind. Then come with me to the newly built house."

"good!"

Lin Heng quickly arrived at the newly built house and immediately opened the Immortal Slave Manual:

[Construction requirements for the Fiery Camp: Met.]

It became.

From now on, his territory will also form a formidable fighting force!

Thinking this, Lin Heng turned to one of the immortal servants and said, "Go to my warehouse and bring over a box of stone bricks."

"Yes, Young Master Lin."

"Teacher, I'll go too!"

Song Jingyu volunteered to help.

"You stay."

Lin Heng stopped her and then looked at the entrance of the new house: "Here, I will build you a special fairy farm."

"what?"

Song Jingyu looked at Lin Heng with surprise and delight: "Really, teacher?"

[Song Jingyu's loyalty has increased by 10, now standing at 63.]

"But there's a prerequisite."

Lin Heng rubbed her head and said, "But from now on, you'll be spending most of your time working here."

"Work?"

Song Jingyu was stunned.

"Um."

Lin Heng nodded: "The array of the Blazing Fire Camp can cultivate fire spirit root fairies who can recover a certain amount of spiritual power. Your job from now on is to stay here and maintain the operation of the array. If you have nothing to do... you can just plant some spiritual herbs here."

There are two prerequisites for operating the Blazing Camp.

One is to consume the spiritual energy in the spirit stones at the core of the formation.

Secondly, just like the Spirit Restoration Array, it requires a fire spirit root fairy bound to the Immortal Slave Manual to stay here.

"Yes, I will definitely complete the task assigned to me by the teacher!"

[Song Jingyu's loyalty has increased by 5, now standing at 68.]

Song Jingyu looked at Lin Heng with gratitude.

Just as my sister said.

Becoming a master's immortal servant means not only avoiding inhumane treatment, but also being able to fulfill one's value just like a disciple of a sect!

So, how should we thank our teachers?

Song Jingyu lowered her head and pondered.

At this moment, the fairy servants brought over the stone bricks.

Yun Qinghe, who had already placed the Thousand Branches Vine Sword on the Spirit Restoration Array, also helped move some stone bricks over, just like these fire spirit root immortal servants.

"Sister...that's right!"

Song Jingyu's eyes lit up, and then she tiptoed and whispered in Lin Heng's ear, "Teacher, tonight I can repay you like an older sister."

"?"

Lin Heng looked at her suspiciously: "What kind of repayment?"

Song Jingyu whispered, "I remember my sister saying that you really enjoy receiving nourishment from my sister's spiritual roots while sleeping, using a pillow as a pillow? Actually... I can do that too!"

"..."

Lin Heng lowered his gaze slightly, his eye twitching slightly: "What you're saying is unnecessary."

"Why? My fire elemental root is very warm! And I promise it won't hurt you, teacher!"

Song Jingyu was eager to try.

But this has absolutely nothing to do with her fire elemental root...

Wait, fire elemental root?

Suddenly, Lin Heng thought of a crucial piece of information: Song Jingyu's first title.

Open the Immortal Slave Manual:

[Celestial Slave Title: Blazing Jade Saintess]

[Title Talent: Blazing Jade Spirit Fire, a powerful flame capable of incinerating all demonic creatures and possessing a refining effect.]

Refining...

Turning to Song Jingyu, Lin Heng asked, "Can your flames refine the demonic energy within my spiritual root?"
