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

"Please fetch some stone bricks from the warehouse."

"Yes, Master."

"Then take out all the spirit stones."

"Um!"

Back in the house, Lin Heng had Mu Tinglan and Yun Qinghe fetch stone bricks and spirit stones.

After obtaining the Thousand Branches Vine Sword in the cave, his Slave Master Manual unlocked two new arrays.

An oasis in the clouds, and a guardian in the forest.

At the entrance, Lin Heng first set up the formation of the forest guards.

It occupies only about half the size of a table.

The formation of the forest guardian was not complicated, and the rules of the formation were similar to the spirit-suppressing tower formation that he had constructed many times.

After he completed the entire array and placed a spirit stone into the array eye, a sapling quickly grew out of the array.

"This is……"

Mu Tinglan and Yun Qinghe watched the sapling grow bigger and bigger, and in the end it stood at the door in the form of a tree person.

And the appearance of this tree-man was almost identical to that of the giant tree-man that the Thousand Branches Vine Sword had transformed into.

Lin Heng stood up and said to Yun Qinghe, "Throw the sword you usually practice with at it."

"it is good."

Yun Qinghe took her iron sword from beside the bed.

"Use force, like... to kill someone."

"Um!"

At Lin Heng's command, Yun Qinghe suddenly threw the iron sword in her hand.

Before the iron sword could even get close to the treant, the treant used its branches to entangle the sword in mid-air.

Immediately, the branches and leaves binding the iron sword tightened abruptly.

The iron sword, which had been perfectly intact just moments before, instantly turned into tiny iron filings that fell to the ground.

Lin Heng went over and picked up the tree man's branches and leaves to examine them.

Even though the branches on the treant were wrapped around sharp blades, there was not a single scratch on them.

Yun Qinghe said in surprise, "This seems to be... a defensive formation similar to the Spirit Suppressing Tower Formation?"

"No, junior sister, it's different from the Spirit Suppressing Tower Formation."

Mu Tinglan shook her head.

"That's right."

Lin Heng smiled, then squatted down and changed one of the stones in the array.

The tree-man also moved from the left side of the door to the right side...

"Oh, right, it can move!"

Yun Qinghe immediately realized its biggest difference from the Spirit Suppressing Tower Formation.

Not only that...

Lin Heng was even more aware that the forest guards had the potential to become even stronger.

Because he could clearly see in the Immortal Slave Manual that there was an upgrade option in the array of the forest guards:

[Nine Seas Goddess Title Effect: Upgrades Forest Guardian]

[Forest Guardian Upgrade: Ancient Tree Roots grant the Forest Guardian greater size and strength.]

However, the reason Lin Heng did not upgrade the forest guard was simply because the spiritual energy it consumed was too terrifying.

A single Xuan Root Ancient Tree costs one hundred spirit stones and can only last for one day.

No matter how hard Yun Qinghe works, she can't withstand this kind of drain...

Moreover, Lin Heng currently has another array to construct, which further increases his demand for spirit stones.

After looking at the "Oasis in the Clouds" in the Immortal Slave Handbook, he simply moved all his spirit stones over there.

Because the requirements for building an oasis in the cloud are not as simple as just using stone bricks.

The entire array can only be constructed using spirit stones that possess spiritual energy!

But as Lin Heng gradually arranged all the spirit stones...

He suddenly stopped constructing the magic array, stood up, and said helplessly, "Never mind, let's put these spirit stones away first and deal with them later."

"it is good."

Mu Tinglan nodded and began to tidy up the spirit stones.

Seeing Lin Heng's helpless expression, Yun Qinghe stepped forward and asked, "Master, is it because you don't have enough spirit stones?"

"Yeah, much worse."

Lin Heng sighed.

Because he had only just tried to arrange the array, he discovered that the array of this oasis in the clouds actually required tens of thousands of spirit stones!

However, Lin Heng had already vaguely discovered from the rules of the formation that the Oasis in the Clouds was definitely worth the consumption of so many spirit stones...

"I'm sorry, Master, Qinghe has been practicing her sword more than usual these past few days..."

At this moment, Yun Qinghe immediately lowered her head and apologized.

But soon, she raised her head and said firmly to Lin Heng, "But Master, please rest assured, I will no longer practice swordsmanship, and will only use spirit stones for you!"

"It's not your fault."

Lin Heng shook his head and said, "After all, the difference isn't just a few dozen or a hundred spirit stones... I estimate that even if you were squeezed dry, you still wouldn't produce as many spirit stones as I need."

"Then, is there any other way?"

Yun Qinghe asked anxiously.

"Another way...that's it!"

Lin Heng suddenly remembered another page in the Immortal Slave Manual.

The title of Goddess of the Vine allows the Thousand Vine Sword to perfectly replicate the Goddess of the Vine...

"Come here."

Lin Heng directly invited Yun Qinghe to their bedroom.

Yun Qinghe stared blankly at Lin Heng, looking at the bed with the spirit-restoring array set up on it: "Master... are you going to start draining me dry?"

However, the surprise on her face quickly turned into determination.

Since the master needs it, then I'll just squeeze myself dry!

In any case, the nature of those with wood-elemental roots is the ultimate in endurance...

"Just put the sword up there."

Lin Heng pointed to the Thousand Branches Vine Sword at her waist.

"what?"

Yun Qinghe was taken aback at first, but after regaining her senses, she immediately placed the sword where she was sleeping: "Master, I've put it away."

The next moment, the Spirit Restoration Array, which had not been operating before, actually started to operate!

Just like when Yun Qinghe is in bed laying eggs...

"It...it can actually provide spirit stones for its master just like I can?"

Yun Qinghe looked at Lin Heng in surprise.

Although this is a good thing, as the master now has more ways to produce spirit stones.

However, at the same time, her mood also became slightly depressed.

The contrast between her original uniqueness and her current inability to be replaced by a sword left her with a sense of loss...

"That makes things much easier."

Suddenly, Lin Heng looked at the Spirit Restoration Array that was operating with satisfaction, and said to Yun Qinghe, "This way, having you by my side won't interfere with the production of spirit stones, and you can also do other things..."

Yup!

Suddenly, Yun Qinghe's eyes lit up.

The egg-laying work for producing spirit stones has already been taken care of by the Thousand-Branched Vine Sword...

Then wouldn't she be able to stay by her master's side at any time?

Moreover, the owner said it would give him more freedom...

[Immortal Slave Yun Qinghe's loyalty +5, now 84.]

"What does Master need me to do now?"

Yun Qinghe immediately looked at Lin Heng expectantly.

"It's about time."

Lin Heng nodded slightly and muttered something, then said, "And now your job is to be the older sister..."

what?

Yun Qinghe stared blankly at Lin Heng.

No wonder the master seems closer to his senior sister most of the time; so the master's hobby is...

"Cough cough cough."

Because of the unique characteristics of her title, Fairy Yingyu, she quietly cleared her throat.

Since this is the master's preference, should I imitate my senior sister's more mature tone of voice...?

"Let's go out and see your new little sister."

"Oh……"

So when the master said "as an older sister," he meant as Song Jingyu's older sister?

Pushing open the door, Lin Heng and Yun Qinghe returned to the courtyard.

However, Song Jingyu was no longer standing blankly at the door, but squatting in a corner of the Immortal Farmer's Spirit Field.

Her red brocade skirt fell onto the muddy field, but she didn't seem to care at all. Instead, she looked curiously at a spiritual herb in front of her.

Song Jingyu excitedly muttered to herself, "So this is the Gathering Yuan Grass? I heard that the requirements for growing it are extremely demanding. I've tried planting it underground several times and failed each time. I never thought I'd actually have a chance to see it..."

"Are you researching cultivation methods for *Gynostemma pentaphyllum*?"

Suddenly, Lin Heng's words interrupted her.

Song Jingyu immediately stood up and turned her head away: "I, I didn't!"

But out of the corner of her eye, she glanced at Lin Heng with anticipation and longing...
