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

Tian Qianchen wrote down the reasons for her departure very clearly.

Even just through written words, Lin Heng could sense that the old man truly didn't want to return to the General Headquarters unless absolutely necessary.

Finally, Tian Qianchen's final words expressed his reluctance to part with the oasis in the clouds:

"This trip will probably last ten days to two weeks."

"If I finish my work and you're still in Jinlu City, I'll definitely come back."

"When you come to the capital, just give me my name and I will send someone to open the door for you."

"Anyway, little teacher, this old man has only one request: please keep a close eye on that kid Xia Feng and don't let him take the fairy slaves to my home in the Cloud Oasis. I'm afraid I'll come back to find my home destroyed..."

After reading the entire letter, Lin Heng put it away, feeling a sense of感慨 (gǎnkǎi, a complex emotion encompassing both emotion and reflection).

Suddenly losing that old guy by my side, it really feels like something's missing.

Just as Tian Qianchen was reluctant to leave his home in the Cloud Oasis...

"Ahem, by the way, young master."

At this moment, the old demon merchant said apologetically, "The spirit stones I was going to use to help you choose a celestial servant, young master, are still at the inn. Could you... reimburse me for them?"

"Inn?"

Lin Heng was stunned.

That's right.

The old merchant truthfully stated, "The innkeeper said that a lot of furniture in Elder Tian's room was destroyed in the explosion, and compensation is required."

"..."

In an instant, Lin Heng suppressed his previous reluctance, waved to Yun Qinghe, and gestured to give the old demon two spirit stones.

Forget about the sentimentality of parting. Let that old bastard go back to the General Administration Headquarters as soon as possible; it'll save me some spirit stones...

However, Lin Heng felt that he probably wouldn't be leaving Jinlu City anytime soon.

Just look at this vast mine and you'll know.

Even with the addition of over twenty new celestial slaves, it will still take considerable time to mine the ore needed for the Nine Seas Goddess statue.

After sending the old demon merchant away, Lin Heng began to plan for this mysterious mine.

After all, the goddess titles he has unlocked now are not only Mu Tinglan's Nine Seas Goddess, but also Yun Qinghe's Manluo Goddess.

If nothing unexpected happens, the future statue of the Goddess Manluo will definitely require a large amount of ore to construct.

Therefore, regarding this mine...

Lin Heng believed the best plan was to develop "sub-mines" within his own territory.

This allows his expertise in array construction to extend beyond the cloud oasis and be applied throughout the mysterious mine.

After thinking for a while, Lin Heng turned to Yun Qinghe and Mu Tinglan and said, "You two go back to the Oasis in the Clouds first, then take out all the spirit stones you got from exchanging the strong grass, open the Spirit Restoration Array, and restore the spiritual energy and spiritual root purity first."

Thanks to the blessing of the Spirit Restoration Array during this period, the spiritual roots of the immortal slaves bound to his Immortal Slave Manual have been significantly improved.

Gesang Nazha: 100%

Song Jingyu: 58%

Yun Qinghe: 79%

Mu Tinglan's level had originally reached over 80%, but because she used the fifth stage ability of the Mermaid Tear Tide-Summoning Flute, it has now been reduced to zero again.

Although the Spirit Restoration Array is not as effective as the Immortal Spirit Spring in restoring strength, the problem is that Lin Heng himself still needs to stay in the mine, so he can only let them recover some strength in this way for the time being...

"Well, Master, I'll be going now."

Mu Tinglan nodded gently.

Just as Yun Qinghe was about to leave with her, Mu Tinglan called out to her, "Junior sister, come back to your master as soon as you recover."

"Um?"

Yun Qinghe was stunned: "But didn't Master tell us to go back?"

Mu Tinglan smiled: "Master didn't rest all night, he definitely needs you."

"Oh……"

Yun Qinghe pursed her thin lips.

Indeed, only I can relieve my master's fatigue...

The two left.

Lin Heng then instructed the two fire-elemental immortal servants brought by Yun Qinghe to guard the entrance of the mine and report to him immediately if anything happened.

He personally found some stone bricks from the mine and began to construct an array in this "sub-mine".

First, there are two spirit restoration arrays.

One is a regular spirit-gathering array.

The other is the same Spirit Restoration Array as the Oasis in the Clouds, but it doesn't have the effect of upgrading Spirit Essence.

After all, with the Thousand Branches Vine Sword in existence, he could completely separate the Thousand Branches Vine Sword from Yun Qinghe in producing spirit stones.

Ordinary spirit-restoring arrays can release the spiritual energy from spirit stones and then condense it to activate other arrays in the territory at any time.

Then, Lin Heng began constructing the forest guards in the mine.

Compared to the Spirit Suppressing Tower Array, which can only stand in a fixed position and requires magical energy to charge, this is a significant improvement.

Forest guards, which can move freely and only require spirit stones to charge, are more suitable as defensive fortifications for this vast mine.

Gradually, it became afternoon.

The immortal slaves that Lin Heng had arranged to rest at the camp after the slave spirit seal was established last night have gradually woken up.

They have now completed the transformation of multiple identities.

From a fairy in the celestial realm to a fairy maiden in Golden Deer City, then a lamb to the slaughter in the mine, and finally a fairy slave to Lin Heng.

So after getting up, they all left the camp with a sense of apprehension.

Although Lin Heng's promises before establishing the slave spirit seal sounded very tempting.

But upon closer reflection, didn't the new regulations of Dawn in Golden Deer City also tempt them at one time?

What if their current master is also like the officials of Golden Deer City, saying one thing and doing another...

correct!

The fairies here all have water and fire spiritual roots.

Back when they were fairy maidens in Golden Deer City, they had heard about the concept of "ice and fire in two worlds" from many wealthy merchants.

Purchasing multiple water-elemental and fire-elemental spirit slaves has become a hobby for wealthy merchants.

That's why their current master saved them...

No.

They couldn't bear to think any further, nor did they dare to fathom the meaning behind the wealthy businessmen's talk of "two extremes of life."

Now, no matter how cruel the future may be, they can only grit their teeth and face it.

After all, the Slave Spirit Seal has already been formed; even if someone wants to die, they need Lin Heng's permission...

However, when they stepped out of the camp, they found many neatly stacked piles of stones in the mine, as well as strange tree people patrolling the area.

They cautiously observed the tree-man for a while, and only after confirming that he would not attack them did they carefully walk to the center of the mine.

As it turned out, upon arriving at the center of the mine, they saw Lin Heng, who had become their slave master the previous night, squatting in front of a pile of stones.

Lin Heng took out a spirit stone and placed it in the middle of the mortar.

A brand new tree-man, just like the ones they had seen before, appeared in the mine.

"That should be about right."

Lin Heng clapped his hands and stretched wearily.

"Master, are these treants in the mine... a formation you created?"

One of the immortal servants stepped forward and asked Lin Heng uncertainly.

"You're awake?"

Lin Heng then realized that he was surrounded by fairy slaves.

He nodded and said, "These treants are used to defend against external enemies. I will later have someone specifically place spirit stones in these array eyes."

The celestial servants were stunned. It turned out that their seemingly exhausted master had spent the entire night building arrays in the mine to protect their safety.

The celestial servants are resting, while their master is working...

How could this be?!

This isn't something that can be faked with just a few words...

"Alright, now that you're awake, go get something to eat and then clean up the mine. After all, last night's demonic tide left behind quite a few corpses and ruins."

Lin Heng waved to the servants, "Perfect timing, I should go and relax too."

But they didn't move.

The two water-elemental fairy servants exchanged glances, then stepped forward and said to Lin Heng, "Master, if you would like to find a place to rest... would you like us to use spirit stones to activate the characteristics of your water-elemental roots to make you more comfortable? We water-elemental fairy servants have the ability to make our master comfortable."

"No need."

Suddenly, a clear, cold voice attracted the attention of the celestial servants.

Yun Qinghe quickly walked to Lin Heng's side and said arrogantly to the servants, "Master, I am enough to relieve your fatigue."

"Um."

Lin Heng nodded. He said that relieving fatigue meant that he knew Yun Qinghe had arrived through Liu Hun Yu Ji's ability.

"Well, alright then...we'll go work for our master too."

The two water-elemental immortal servants were stunned for a moment, then nodded in understanding.

After all, the characteristics of the wood elemental root have a more direct effect on relieving fatigue.

But as they turned around, they suddenly heard a noise behind them.

So they turned their heads to look again out of curiosity.

Their master was already enjoying himself, embracing the supple branches and absorbing the tender leaves of the wood spirit root...

Wood Spirit Root Fairy, to relieve fatigue, doesn't seem to need this kind of contact, right?

and many more!

Suddenly, they realized an even more crucial problem.

The white-clad fairy did not seem to activate the spiritual root's characteristics through the spirit stone.

In this demonic calendar era where spiritual energy is depleted, how can one unleash the characteristics of a spiritual root without the spiritual energy within a spirit stone as a driving force?

Could it be that……

The white-robed fairy's spiritual root still harbors inexhaustible spiritual energy?!
