"Huh?!"

Mu Jinyu saw this scene and couldn't help but look at the Corpse-Wrapping Cloth radiating a faint brilliance all over. He felt a mix of surprise and delight, completely unexpected.

He had originally planned to give up on these scattered bits of Luminous Substance, feeling it was too much of a waste of time.

But he still felt a bit of regret in his heart.

Unexpectedly, the Corpse-Wrapping Cloth seemed to understand his intentions and summoned all the scattered Luminous Substance back.

"Speaking of which, what exactly is this material? Is it Soul Light? Or something else?"

Mu Jinyu watched the continuously surging Luminous Substance, thinking it seemed to have a good effect on the Earth Emperor's Tome, a Soul-related Magic Treasure.

But it seemed to be useless for other Magic Treasures.

He couldn't figure out what it was.

"Shoo, shoo, shoo!!"

As time slowly passed by.

Soon, bit by bit, the Luminous Substance gathered together.

Finally forming a mass of Luminous Substance about the size of a human head.

This showed just how much energy the Corpse-Wrapping Cloth had scattered outside...

After waiting for more than ten minutes.

No more Luminous Substance returned.

Mu Jinyu knew that all the Luminous Substance scattered by the Corpse-Wrapping Cloth had been summoned back.

And the Earth Emperor's Tome stored in his Dantian was slightly excited, eager to appear and refine and devour these Luminous Substances.

But perhaps thinking of Mu Jinyu's previous attitude, the Earth Emperor's Tome only weakly expressed a desire and didn't act impulsively.

"Hmm..."

Mu Jinyu also pondered, thinking about how to distribute this head-sized Luminous Substance.

Logically, these were originally scattered energy from the Corpse-Wrapping Cloth and should be returned to it.

But the Corpse-Wrapping Cloth didn't seem to care about these scattered energy.

Otherwise, it wouldn't have acted only after he transmitted a sense of regret to summon these scattered Luminous Substances back.

And once the Luminous Substances were gathered back, it didn't seem to want to retrieve them, letting them remain outside.

It seemed like it was waiting for him to deal with them?

Could it be that the Corpse-Wrapping Cloth wanted to make good relations with the Earth Emperor's Tome, so it did this?

Mu Jinyu wasn't sure, so he tried to communicate with the Corpse-Wrapping Cloth.

Finally confirming that the Corpse-Wrapping Cloth indeed didn't need the Luminous Substances. It summoned them back partly because the Earth Emperor's Tome wanted them and partly because he felt it was a waste.

"Then should I give it to the Earth Emperor's Tome?"

Mu Jinyu said with slight embarrassment.

Feeling like an unfair parent, wanting to give the sister's toy to the brother.

It made him feel a bit guilty.

As soon as he spoke.

The Corpse-Wrapping Cloth immediately conveyed a thought of agreement.

Since that was the case, Mu Jinyu finally gave all the head-sized Luminous Substance to the Earth Emperor's Tome.

And after the Earth Emperor's Tome devoured this Luminous Substance, it also emitted a faint glow all over, similar to the Three-Leaf Youlian that swallowed a strange coffin lid, seemingly digesting the large mass of Luminous Substance.

Soon, the Earth Emperor's Tome finished digesting this mass of Luminous Substance.

Afterward, it also sent a message of gratitude to the Corpse-Wrapping Cloth.

No longer having that wary and cautious demeanor, nor the previous eagerness to swallow the other.

"Hmm, good, it's best if they get along..."

Seeing this, Mu Jinyu was quite happy.

Then, seeing there wasn't much else to explore in the Secret Realm, he returned to the starting point, opened the passage to the Secret Realm, and passed through the light curtain.

He exited the Secret Realm.

"Buzz!!"

Mu Jinyu turned around and saw the blue light curtain behind him disappear.

And by the pile of rocks where the Secret Realm was located, Xuu Changqing was nowhere to be seen.

Probably seeing him enter the Secret Realm, there was no need to wait outside, so he went back to handle matters like moving his parents' graves?

Mu Jinyu thought for a moment and decided not to return to the Xuu Family to bid farewell to Xuu Changqing, not wanting to disturb him.

He just used his Identity Plaque to send a message to Xuu Changqing, notifying him that he had left the Secret Realm and was returning to Dongyue Mansion.

...

A day later.

After some time of Void Shift.

Mu Jinyu finally hurried back from Muyun Province to Donghua Province.

"Finally back. I guess the formal promotion for students is about to start?"

Mu Jinyu returned to Donghua Province, then went back to the Examination Mansion, entered the Teleportation Platform, and entered Dongyue Mansion.

"Seems like it hasn't started yet..."

Mu Jinyu pondered slightly, then walked towards the Intermediate Student's residence, Courtyard No.96.

Arriving at Courtyard No.96.

After entering, Mu Jinyu found Chu Huannian and the others were there.

"Brother Jinyu, you're back? How was the mission?"

Ji Xiaoyun saw Mu Jinyu return and couldn't help but show a bright smile, greeting sweetly.

"Mm, just completed the mission. By the way, hasn't the promotion selection started yet?"

Mu Jinyu nodded and answered the question, then asked them.

"Not yet, there's still two days." Chu Huannian replied.

"That's good..." Mu Jinyu showed a relieved expression.

Seeing this, Chu Huannian asked, "Why? Are you planning to participate too?"

She remembered that Mu Jinyu initially didn't want to participate in this promotion selection, but now since he asked with such concern, was he planning to join?

"Yes, I do plan to participate in the Senior Student promotion selection."

Mu Jinyu nodded.

He originally wasn't very interested in these things.

But now, he really needed to enter the Advanced Gravity Training Room for cultivation.

It's not just about needing academic credits to enter, but also requiring someone to ensure his safety.

Otherwise, he feared he might really die in there.

But with his Intermediate Student status, it was clearly not enough to gain the attention of the Mansion Master and the Institute Head of the College of Physics.

He still needed to become a Senior Student first, then find a way to get their help.

This way, the success rate would obviously be much higher than with his current Intermediate Student status.

So after considering for a while, he decided to participate in the promotion selection.

"Alright, I'll go out for a bit first to pay back some academic credits I owe a mentor!"

After chatting with Chu Huannian and the others for a while, Mu Jinyu remembered he still owed the old mentor fifty academic credits, so he left the courtyard again, heading towards the cultivation area over there.

Soon, Mu Jinyu arrived at the gravity training area and saw the old mentor again.

"Kid, finally here, huh? When are you going to pay back those academic credits you owe me? I thought you ran away and weren't coming back..."

The old mentor saw Mu Jinyu appear, slightly stunned, then showed a teasing expression and joked with him.

Mu Jinyu smiled and said, "I had to go out for a mission, of course I needed time to earn credits, I couldn't exactly rob someone, right."

"So how many credits did you earn?" The old mentor asked with a smile, "You owe me fifty credits, and if you want to enter the Advanced Gravity Training Room, an hour is one hundred credits. You need to earn at least one hundred fifty credits, right?"

"In just these few days, you didn't just earn fifty credits to pay off your debt, did you?"

Mu Jinyu shook his head and said, "No, I earned one thousand credits, so for now, that's just enough."

"After advancing to a Senior Student, there will be bonus credits too, so I won't have to worry then!"

"Huh?!" Hearing Mu Jinyu's words, the old mentor froze, unbelieving, and said, "How is that possible? You earned one thousand credits in just these few days?"

"What task could earn so many credits?"

"I don't believe it!"

The old mentor shook his head vigorously, firmly denying this, thinking Mu Jinyu was teasing him!
