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

In today's world, Lin Heng didn't think his kind neighbor would be so generous as to share spiritual herbs with him.

After all, for anyone, a large quantity of spiritual herbs would be an invaluable treasure.

Xia Feng told him all of this information.

But Xia Feng himself was clearly just a poor man living in a slum...

"...Alright, Young Master Lin, I won't hide it from you anymore!"

After hesitating for a few seconds, Xia Feng looked up at Lin Heng and said, "After digging down into Old Zhang's ancestral grave, I unearthed a tunnel, and it's true that there are many spiritual herbs inside. But..."

"But what?"

Lin Heng knew that the real key was what followed.

"But I think I heard the howling of monsters inside..."

Xia Feng's face turned pale, clearly indicating that he had been badly frightened while in the tunnel.

"But there really are a lot of spiritual herbs inside, I'm not lying to you!"

Xia Feng patted his stomach firmly, then whispered, "How about it, Young Master Lin? Should we work together to think of a way... to secretly get those spirit herbs out? If we succeed, we'll be rich!"

Judging from the fanaticism and greed in his eyes, Lin Heng was certain that Xia Feng was telling the truth this time.

However, Lin Heng remained calm: "What are the chances that we can steal those spiritual herbs right under the monsters' noses without them noticing?"

"this……"

The excitement in Xia Feng's eyes noticeably diminished.

"What are the chances that we'll survive if the monsters discover us?"

"...There is no probability."

Lin Heng's two questions completely demoralized Xia Feng.

He clenched his fists and said, "Damn it, I can't die like this!"

Lin Heng nodded with satisfaction.

Money is important, but you can't risk your life.

"Damn it, I haven't even enjoyed the immortal slave I bought for long, it's such a waste for him to die like this!"

Xia Feng gritted his teeth, as if he had made up his mind.

Then, there was relief...

"Luckily, I brought two spirit herbs with me, so I can exchange them for some money! Tomorrow I'll go to the market to check the prices; maybe I can even buy a high-grade one from a major sect to play with!"

"..."

"Let's go, Young Master Lin. Oh, by the way, consider that spirit herb a gift from me!"

Watching Xia Feng's departing figure, Lin Heng felt a surge of emotion.

It must be said that this kind neighbor truly considered him a friend; otherwise, he wouldn't have given him the expensive medicinal herbs.

"It seems that after bringing the spiritual herbs up, I should at least share some with him..."

Muttering to himself, Lin Heng slowly returned home.

Indeed, he dared not venture into a tunnel inhabited by monsters.

But what if he had two more fairies at the mid-stage of the Nascent Soul realm and the late-stage of the Spirit Realm by his side?

"How's the digging going?"

When Lin Heng got home, he saw Mu Tinglan carrying a shovel as she returned from the newly built room at the back.

"The master has been dug up."

Mu Tinglan caught her breath, put the shovel down beside her, and leaned against the wall.

Lin Heng nodded slightly, then picked up a spirit stone from under the bed: "You all come with me."

Yun Qinghe nodded to Mu Tinglan and followed Lin Heng.

From now on, this will be a hot spring room.

Seeing the huge pit in front of him, Lin Heng had already given the room a name.

He squatted down beside the pit and looked around. Immediately, a prompt from the Immortal Slave Manual popped up in front of him:

[The conditions for constructing an array for the Immortal Spring are met. Shall we proceed with constructing the array?]

"Bring me some stone bricks."

"Yes, Master."

Not long after, Mu Tinglan and Yun Qinghe each moved some stone bricks and placed them next to Lin Heng.

Then, Lin Heng began to carefully arrange the stone bricks.

"Junior sister, what's wrong with Master...?"

Mu Tinglan spoke very softly, afraid of disturbing Lin Heng by speaking too loudly.

"The master is a powerful array builder."

Yun Qinghe explained in a low voice, "The demonic tide of the past few days was resolved by the Master using the Spirit Restoration Array and the Demon Concealment Array."

"A formation master?!"

Mu Tinglan's eyes widened in surprise. "But isn't there no spiritual energy left now? And the Spirit Restoration Array can only gather spiritual energy..."

"But the master's spirit restoration array is different."

Yun Qinghe gently shook her head: "It seems that the master has changed the structure of the Spirit Restoration Array, which can generate spiritual energy by relying on my wood spirit root. That's how the spirit stones under the bed are produced."

"Can it generate spiritual energy out of thin air?!"

Mu Tinglan was even more surprised.

You must understand, this is a demonic calendar year where spiritual energy is depleted.

Even powerful figures like the Snow-Maned Lion Demon and the City Lord's Mansion cannot produce spiritual energy!

But now, her junior sister is telling her that their slave owner, who lives in the slums, can do it with ease...

"But even for a formation master, a room this small..."

Seeing that her senior sister had the same question as her, Yun Qinghe interrupted, "The Spirit Restoration Array only used the space of one bed, the one we sleep on."

"Then our master's array-building level might not have reached that of a high-level array builder?"

Mu Tinglan watched Lin Heng's retreating figure with growing astonishment.

As Yun Qinghe's senior sister from the same sect, she has a better understanding of array builders.

The levels of array builders are divided into beginner, intermediate, advanced, and master.

Even a sect like the Yunling Sect, which they belong to, is considered quite good in the Immortal Realm, but it can only hire one intermediate array master to help with array construction.

Only advanced, or even master-level, array builder can narrow the array's scope to its extreme.

Array builders of this caliber are usually independent and do not belong to any sect.

Do you want them to take action?

Even if it were a more powerful sect, even if the sect leader personally went to invite them, they might not be able to persuade them...

"I don't know, after all, the master has only constructed a low-level formation for now, but the level must be quite high."

Upon hearing Yun Qinghe's words, Mu Tinglan couldn't help but glance at her junior sister.

In the past, none of those proud male cultivators had ever caught the eye of her.

But at this moment, Yun Qinghe's gaze towards their master clearly carried admiration...

Suddenly, the sound of flowing water gradually came from nearby.

Mu Tinglan and Yun Qinghe also turned their gazes forward.

Beside him, the spirit stone that Lin Heng had placed in the center of the array emitted a ray of light.

In the middle of the pit, a spring of clear water suddenly appeared and gradually filled the pit.

The golden glow shimmering above the spring water is the spiritual energy floating on its surface…

This is the Spring of Immortal Spirits!

Mu Tinglan immediately recognized Lin Heng's current formation.

In the past, the Immortal Spring was a formation used by major sects for their core disciples to cultivate.

Unfortunately, their Yunling Sect was not of a high enough level to hire a formation master who could create formations that could summon the Immortal Spirit Spring.

However, on one occasion, she accompanied the sect leader to an ancient sect, where she had the good fortune to witness the Immortal Spring...

"Listen to the Waves".

Suddenly, Lin Heng turned around and looked at Mu Tinglan: "You go and rest outside first."

Mu Tinglan was taken aback for a moment, but quickly nodded and said, "Yes, Master."

She turned and left.

Then, Lin Heng jumped directly into the Immortal Spring.

Subconsciously, Yun Qinghe shifted her gaze elsewhere, her face flushing.

"Master, then I..."

"Get down."

"what?"

"Let's wash together."
