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

"The properties of the Purifying Spirit Crystal?"

Lin Heng and Yun Qinghe both looked at Song Jingyu with suspicion.

"That's right!"

Song Jingyu said confidently, "For example, the purification crystal that my teacher gave me was transformed from a Golden Core Realm demon and a Nascent Soul Peak Demon."

"When I was absorbing it, I felt that the spiritual energy within was more suitable for cultivators in the Spirit Realm or Nascent Soul Realm."

"If you, teacher, absorb this, you'll at least reach a higher level!"

"However, by the time I sensed this, I had already absorbed all the spiritual energy..."

After saying that, Song Jingyu stuck out her tongue shyly.

"In other words, the closer a cultivator is to transforming into that spirit crystal demon, the more effective it will be."

Yun Qinghe nodded thoughtfully and then looked at Lin Heng.

"Therefore, Jingyu, whose realm is far beyond Chu Jiangfeng's, doesn't see such a noticeable improvement..."

Although Lin Heng did learn how to better utilize the Purifying Spirit Crystal through Song Jingyu's absorption of it, his tone sounded somewhat helpless.

After all, Song Jingyu is now at the Nascent Soul stage, and finding a Dark Sect cultivator of the same level is not an easy task.

"Back when you were in the Immortal Realm, were cultivators at the Nascent Soul and Enlightenment Realms as rare as they are now?"

Turning his head, Lin Heng asked Yun Qinghe.

"Master, are you referring to before the demonic tide arrives?"

Yun Qinghe looked at Lin Heng.

Seeing Lin Heng nod, she also told Lin Heng the truth: "In fact, as far back as I can remember, almost all the core disciples painstakingly cultivated by the major sects in the Immortal Realm have reached the Nascent Soul Realm."

"Although I was still in the Nascent Soul stage before I fell, the sect leader told me that my talent had not yet been realized."

"And those who oversee a sect, such as the sect leader and the sect elders, have all reached the Enlightenment Realm..."

That's true.

Lin Heng clearly remembered that when he formed the Slave Spirit Seal for Yun Yue, Yun Yue was already in the late stage of the Enlightenment Realm.

This is also what puzzled him: "Why is it that, apart from a handful of sect leaders, there aren't many cultivators at the Enlightenment Realm in the Immortal Realm right now?"

"Teacher, I know that!"

Song Jingyu volunteered, saying, "I used to... I used to hear Sister Lan tease me, saying that I missed the best time of the Immortal Ancient Era!"

"The best time?"

Lin Heng nodded, signaling her to continue.

"She said that during the most prosperous period of the Immortal Ancient Era, everyone's spiritual root purity improved rapidly, and the speed of cultivation was several times that of before."

Song Jingyu recalled, "And this is all because of the Hongmeng Empress, who caused a qualitative change in the spiritual energy of the Immortal Realm."

"The Primordial Empress?"

Upon hearing this brand new name, Lin Heng turned to look at Yun Qinghe, who had personally experienced the Immortal Ancient Era.

"I...I don't know..."

Yun Qinghe said somewhat awkwardly, "Back in the Immortal Realm, I was only focused on cultivation and didn't know much about the figures who appeared in the Immortal Realm's history. But the spiritual energy in the Immortal Realm was indeed easier to absorb back then than it is now."

After all, when Lin Heng first inquired about the Five Source Immortal Venerable, she had never heard of him, and it was Mu Tinglan who had a vague impression of him in the end.

As Yun Qinghe was Yun Yue's direct disciple, and given her dedication to cultivation, it was perfectly normal for her to be oblivious to everything else and only focused on improving her cultivation level in the past...

"Master, I'm sorry."

Seeing Lin Heng's somewhat helpless expression, Yun Qinghe quietly took one of Lin Heng's hands and held it in her palm.

I'm not blaming you.

Lin Heng shook his head, then looked at Song Jingyu: "I was thinking that in the current Immortal Realm, it's very likely that the so-called Hongmeng Empress hasn't appeared yet, so there aren't many cultivators who have reached the Nascent Soul Realm. Therefore, if we want Jingyu to reach the Enlightenment Realm as soon as possible, it might be difficult to achieve it through purifying spirit crystals..."

"Teacher, no!"

Suddenly, Song Jingyu smiled mysteriously: "Look closely at me, haven't I changed a bit?"

"Um?"

Lin Heng stared intently at her, while simultaneously opening the manual about her as a fairy slave.

[Immortal Slave Song Jingyu, Loyalty: 150, Spiritual Root Purity...]

Holy crap?!

Lin Heng's eyes widened instantly: "When did your spiritual root purity level increase to 90?"

Song Jingyu chuckled, "The Spirit Restoration Array in the Immortal Realm seems to be even more effective than the Demonic Calendar!"

Spiritual Restoration Array...

Of course, Lin Heng knew that the two spirit restoration arrays in the room had actually been upgraded by him to the Spirit Abundance Spirit Restoration Array.

After all, the immortal realm has pure spiritual energy, unlike the demonic calendar which required spirit stones to operate.

Therefore, in order to build a cloud oasis in the future, Lin Heng simply upgraded them as a matter of course.

"Huh? Master, Master doesn't know?"

At this moment, Yun Qinghe also turned her head and looked at Lin Heng in surprise.

Lin Heng paused for a moment, then immediately went to check Yun Qinghe's information:

[Immortal Slave Yun Qinghe, Loyalty: 285, Spiritual Root Purity: 96!]

Holy crap, holy crap, holy crap!

Lin Heng was so excited that he kept exclaiming "Holy crap!" three times.

Unexpectedly, sending my immortal servants to the immortal realm has improved the purity of their spiritual roots.

It should be noted that one of the conditions for constructing the Yun Qinghe Namanluo Goddess Statue was to raise the purity of the spiritual root to 100%!

Song Jingyu patted Lin Heng on the shoulder and said with a smile, "Teacher, don't be so excited. My spiritual root purity has improved now, so my cultivation speed will definitely be faster than before in the Demon Calendar. Hmm... the Enlightenment Realm, I'll reach it sooner or later!"

"Young Master Lin!"

At this moment, Yu Zhiyue, who had just been in the courtyard, hurriedly pushed open the door and entered.

Seeing that Lin Heng and the other two had turned to look at her, Yu Zhiyue said anxiously, "Just now... the disciples of the Immortal Alliance sent word that there are Dark Sect disciples lurking less than five miles outside our North Gate!"

"Walk."

Lin Heng immediately called everyone to go, and Yun Qinghe also immediately took her Thousand Branches Vine Sword and followed.

Although it is difficult to find Dark Sect disciples in the Nascent Soul stage, there are plenty of Dark Sect disciples in the Spirit Realm who are suitable for him, or in the Golden Core stage who are suitable for Yu Zhiyue!

Originally, Lin Heng's gaze fell on Yu Zhiyue, and he wanted to suggest that she come along as well.

Before he could even speak, Yu Zhiyue followed along on her own...

Led by a fairy from the Immortal Alliance waiting outside the farmhouse, Lin Heng and the others flew towards their destination using their spiritual power after leaving the city.

"Lord Lin Heng, this is the place."

The fairy from the Immortal Alliance pointed downwards.

A Dark Sect disciple, who had transformed into a demonic rat, was using its two somewhat broken teeth to unleash demonic energy at a Golden Core Realm Yunling Sect fairy.

"The fairy's clothes are the ones worn by our Yunling Sect when managing the cultivation of spiritual herbs."

Yun Qinghe frowned slightly and simultaneously channeled her spiritual power into the Thousand Branches Vine Sword.

As the fairy mark on her forehead and the vines on the Thousand Branches Vine Sword both lit up with a verdant glow, the fairy who had led the way couldn't help but glance at her with a puzzled look.

Our Yunling Sect?

She wondered to herself, "When did Lord Lin Heng's lover join the Yunling Sect?"

You should know that she herself was a fairy who had stayed in the Yunling Sect for nearly a hundred years...
