When Duan Yi opened his eyes again, he had already returned to the first secret realm of the underground palace.

But Duan Yi had not left yet, and stood at the door of the teleportation array, staring at the fragments of the spirit-gathering stone in his hand in a daze.

"Although the system's attribute panel detected that the fragment of the Spirit Gathering Stone is of orange quality, why do I feel that except for emitting a faint blue light, I can't feel any power?"

"It's really strange."

Duan Yi tried to inject spiritual power into the fragments of the Spirit Gathering Stone, but it still did not play any role.

"Forget it, let's put it away first. I'll find some time to ask the teacher to see what this spirit-gathering stone is."

After observing for a while, Duan Yi received the fragments of the Spirit Gathering Stone into the storage ring. At the same time, he summoned all his three strange beasts back and walked out of the underground palace with great strides.

As Duan Yi left the underground palace, the Panlong Stone Pillar gradually rose, and the original entrance to the underground palace disappeared.

The buzz-headed uncle next to the Panlong Stone Column pulled out the small card from the card slot and looked at Duan Yi several times again.

"Bronze Five Stars, it seems that this day's cultivation has made you more diligent."

The buzz-tie uncle noticed Duan Yi’s current cultivation level, nodded slightly, and said.

"Yes, this holy place of cultivation is really great. Unfortunately, I can only stay for one day, otherwise I will definitely be able to break through to the silver level in one fell swoop." Duan Yi said to the buzzing uncle after walking out of the underground palace.

"If you want to enter in the future, it depends on yourself. If you are talented enough, hard-working enough, and are noticed by the teacher, you still have the opportunity to enter for free, so don't worry."

The buzz-tie uncle naturally knew about Duan Yi and also praised this young man very much. If it were not for his responsibilities and needed to guard the first secret realm, he would definitely apply to guide Duan Yi in person.

"Well, I will keep working hard."

"By the way, teacher, do you know what the Spirit Gathering Stone is?"

Duan Yi was about to leave, but suddenly his eyes lit up, stopped and turned to ask.

The buzz-haired uncle in front of him should also be a teacher at Yanhuang Academy, otherwise his cultivation level would not be so high. Moreover, he has always been in the first secret realm, so he might know something. Duan Yi was thinking about seeing from him whether he could know what the Spirit Gathering Divine Stone was.

"Spiritual Gathering Stone?"

After hearing Duan Yi's words, the buzz-headed uncle's pupils suddenly shook and asked in surprise: "Where did you hear this spirit-gathering divine stone?"

"What I saw from...some ancient books is just curious and want to know about it."

Duan Yi originally wanted to tell the buzz-tie uncle directly that he had obtained fragments of the spirit-gathering divine stone in the first secret realm, but after thinking about it carefully, he felt that it was inappropriate.

The fragments of the Star Moon Bird's Spirit Gathering Stone should have been obtained by accident. If the Yanhuang Academy knew that the orange-quality spirit stone in this first secret realm had been mined long ago, and where would Duan Yi be able to get it?

So Duan Yi believes that this must be a secret that has not been discovered by Yanhuang Academy and I don’t want to explain it explicitly at the moment.

"So that's it. Unfortunately, I don't know what this spirit-gathering divine stone is."

The buzz-headed uncle shook his head slightly and said, "But I don't know the Spirit Gathering Divine Stone, but I know what the Divine Stone is."

"The so-called divine stone is actually a golden-quality spirit stone. It is very rare, almost as precious as the spiritual treasure, and generally has very powerful power."

"I have also read an ancient book that introduces an unknown divine stone, which is used to set up a sealing array. Unfortunately, what is the sealing, it is unknown."

"If nothing unexpected happens, this spirit-gathering divine stone should also be a very powerful golden quality divine stone, but as for what its function is, this teacher doesn't know."

"If you want to know, you can find time to go to Yanhuang Academy Library. The library director is knowledgeable and should be clear."

The buzzing uncle is also a teacher at Yanhuang Academy, so he is still very happy to answer questions from students.

"Okay, thank you teacher."

Duan Yi bowed slightly at the buzz-headed uncle, then turned around and left here, and walked towards his classroom.

Although this buzz-headed uncle didn't know it, at least Duan Yi understood one thing, that is, the golden-quality spirit stones belong to the ranks of divine stones and can also be used as seal formations.

When Duan Yi heard the words of the buzz-haired uncle, he immediately recalled the dark environment in the first secret realm.

Why are there fragments of the Spirit Gathering Stone inside, why is there an invisible barrier, and why is the Xingyue Bird still lost after entering? Duan Yi began to wonder if the dark environment was once a sealing array, but later it was broken, and the Spirit Gathering Stone also shattered and turned into a large number of fragments.

But what is the lake water that emits blue light and has extremely rich spiritual power? Why is there a floating stone platform? For a while, Yi had countless questions in his mind.

Duan Yi vaguely began to have a hunch that if he unlocked the secret of the fragment of the Spirit Gathering Stone, he might find a huge secret.

"It seems that I need to find some time next week to go to the Yanhuang Academy Library to have a good look."

Duan Yi was walking towards the classroom while thinking about those questions in his mind.

......

Before he knew it, Duan Yi came to the first-grade teaching building and took the elevator to his classroom.

Today is Friday, and there is also an open class, which is a medical course. Just listening to this name, Duan Yi knew that it should be explaining the medical issues of strange animals to students.

In fact, Duan Yi has a system panel, which can tell at a glance how the alien beast is and how to treat it. Therefore, this medical course is not necessary for Duan Yi to attend.

But why Duan Yi came still? It was mainly because he had to go to open classes twice a month, and if he performed well, he could be rewarded with points by the teacher, so Duan Yi came over directly.

After leaving the elevator, Duan Yi habitually walked to the regular teaching classroom, but found that there was no one inside.

"Oh, I almost forgot. It seems that Teacher Cheng Ling had reminded me last time that some explanations of special courses are required for special courses."

Duan Yi was stunned for a moment and immediately ran towards the special classroom.

At this time, it was already past 8 o'clock, and the teachers who explained the medical course had arrived long ago. The students in the class did not arrive, only about one-third of them, and the rest did not come because they were open classes.

"Report."

Duan Yi knocked on the door lightly and shouted politely at the teacher in the special classroom.
