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

Lin Heng, who entered the livestock farm with Tao Hongzhou, heard that Song Jingyu seemed to have cried at the end.

After all, he had already disappeared for some time, except for Mu Tinglan.

I've only been with them for a short time, and now I have to go somewhere else on my own...

He himself felt a mix of emotions about the sadness of parting.

After all, since coming into this world, they have been the people Lin Heng has come into contact with the most.

Even now, thanks to the enhancements provided by the Immortal Slave Manual, he possesses abilities that are powerful enough to rival those of the world today.

However, without them by his side, Lin Heng felt that it was not just a matter of losing combat power.

But he also knew.

I absolutely must go to this ancient and mysterious realm hidden in the cave.

Because this demonic tide served as a very good warning.

With a large number of demonic generals appearing, even though Lin Heng believed he had improved quickly enough, he was still helpless against such a powerful demonic tide.

Even their eventual dissipation was due to the disappearance of the demonic energy that had possessed Bao Haifeng.

If he doesn't find a way to improve, he might not be able to handle an even stronger demonic tide next time.

Although he was only allowed to enter the Immortal Ancient Secret Realm alone, and he didn't know what was inside or how long he would have to stay there...

But at least, this Immortal Ancient Secret Realm was specifically shown to him in the Immortal Slave Manual.

Therefore, Lin Heng believed that entering this ancient immortal realm would allow him to obtain even more powerful abilities from the Immortal Slave Manual...

With Tao Hongzhou leading the way, the two of them traveled without any obstacles.

"Lord Lin Heng."

As they began ascending the steps leading down into the cave, Tao Hongzhou kindly reminded them, "Have you made arrangements for your immortal servant?"

"Yes, everything is arranged." Lin Heng nodded.

Tao Hongzhou nodded slowly: "That would be best. After all, although this demonic tide at Zaxi Pass is a special case on a small scale, it is second only to the demonic tide that opened up the demonic calendar. If we don't make arrangements in advance, we may have difficulty dealing with it."

Lin Heng smiled easily: "Some of them know how to use the Demon Detector, so making preparations in advance shouldn't be a big problem."

"A celestial slave?"

"Um."

Tao Hongzhou was taken aback.

However, considering Lin Heng's way of getting along with his immortal servant, he nodded and said, "I really didn't expect that you would teach the art of array construction to your immortal servant."

As he spoke, he couldn't help but shake his head with a wry smile.

In this respect, he felt he was even inferior to a celestial servant...

They remained silent the entire way until they reached the depths of the cave.

Now, the array in the underground cave is under strict guard by the General Administration.

Tao Hongzhou waved to the guards blocking his way, then extended his hand in invitation, saying, "Lord Lin Heng, please."

"it is good."

Lin Heng took a deep breath and then walked to the core of the array.

[Enter the Immortal Ancient Secret Realm? (Only the slave master is allowed to enter the Immortal Ancient Secret Realm.)]

The prompt from the Immortal Slave Manual appeared before my eyes once again.

This time, Lin Heng was fully prepared and did not hesitate, choosing "yes" directly!

The instant he made his choice, the power of the rules in the array began to operate rapidly, covering Lin Heng's body.

As a layer of spiritual energy enveloped Lin Heng and emitted a dazzling golden light, the array was fully operational!

"This, this is..."

The guards standing next to the formation were dumbfounded.

Lin Heng, a living, breathing person, simply vanished right under their noses!

"Don't be surprised."

Tao Hongzhou calmly said, "Lord Lin Heng has already gone elsewhere... Next, according to the princess's instructions, unless Lord Lin Heng returns safely from the formation, we must protect the formation to the death."

"yes!"

……

The feeling of entering the Immortal Ancient Secret Realm is similar to the feeling of using the Source Water Path for teleportation, but it is not quite the same.

Lin Heng felt as if his mind was being pulled.

During the struggle, he actually lost consciousness!

Until it seemed like someone patted his face...

"Hey kid, wake up!"

"Boss, could this guy be dead?"

"That's not right. His pulse is perfectly normal... Could it be that the mortal princess brought some kind of mind-altering drug to the immortal realm after she became an immortal?"

"What should we do then? Should we still go and peek at those fairies taking a bath?"

"I'll try again... Holy crap!"

Suddenly, Lin Heng's eyelashes trembled slightly.

Upon opening his eyes, he found himself seemingly in a cave, with four menacing-looking middle-aged men in front of him...

"Who are you?"

Lin Heng frowned, then his heart skipped a beat.

Because he could clearly sense that these four middle-aged men all possessed the aura of good spiritual roots!

Logically speaking, since the beginning of the Demonic Calendar, the spiritual roots of mortals should have been exhausted.

Even when using magic, it's done through other means.

But how could these four people have real spiritual energy fluctuations?

Wait, something's not right...

Lin Heng looked around.

He discovered that not only these four people, but also the surrounding environment, were filled with spiritual energy.

Lin Heng had only seen such a spiritually rich environment before, in the Source Water Dream, with Mu Tinglan.

"Holy crap, kid, you scared the hell out of me!"

At this moment, one of the four people in front, a middle-aged man wearing a black eye patch, muttered a curse under his breath.

Seeing them about to get angry but not daring to raise their voices, Lin Heng couldn't help but wonder, "What are you doing?"

It's not that I'm so carefree after just entering the Immortal Ancient Secret Realm and encountering strangers.

Rather, Lin Heng had already sensed their strength.

The strongest middle-aged man was only at the peak of Foundation Establishment, while the middle-aged men who appeared to be his three underlings had barely reached the Foundation Establishment stage.

"Damn it, shouldn't we be asking you that?"

The blindfolded man leading the group sized Lin Heng up and down: "You... could you have just ascended to the Immortal Realm too?"

"The Immortal Realm?"

Lin Heng paused for a moment.

correct!

Mu Tinglan had said that back when they were in the dream world of the source water.

Such abundant spiritual energy seems to belong only to the former immortal realm…

Lin Heng had a vague guess, but he wasn't quite sure.

After thinking for a moment, he pretended to be confused and scratched his head: "Brothers, I did just ascend to the Immortal Realm and have been asleep for a long time... Could you tell me what year it is?"

"Kid, are you still half asleep?"

Behind him, one of his subordinates said speechlessly, "Right now, of course, it's the Immortal Ancient Era, year 73758!"

"73758..."

The Immortal Ancient Era is the Demon Calendar Era that began in 74242.

and so……

Lin Heng couldn't help but gasp.

That ancient immortal realm actually transported me to the immortal realm more than four hundred years ago?

"Damn it, why are you wasting your breath talking to him!"

At this moment, the man with the eye patch slapped the subordinate who had just spoken to Lin Heng in an annoyed manner.

"Don't forget, we came to see the fairies bathing! We just happened to run into someone like this, of course we have to..."

Suddenly, the blindfolded man looked at Lin Heng, rolled his eyes, and then gave him a friendly smile.
