"If you don't believe it, then don't."

Mu Jinyu was too lazy to argue, so he said directly, "Mentor, please take out your Identity Plaque, and I'll return the credits to you."

"Alright."

The old mentor took out his Identity Plaque, curious to see how many credits Mu Jinyu would return to him.

"Click!"

Mu Jinyu then took out his Identity Plaque and tapped it against the mentor's, transferring over fifty credits.

The old mentor's eyes widened slightly, filled with disbelief.

Because on Mu Jinyu's Identity Plaque, there were indeed more than a thousand credits.

After returning fifty credits, there were still nine hundred and fifty-three credits left.

Did he truly earn a thousand credits in just a few days?

How did he earn them?

As a mentor, making a thousand credits would require quite some effort!

"Hey, did you borrow those credits from others, or did you actually earn them by completing tasks? It feels unbelievable to me."

The old mentor couldn't help but ask Mu Jinyu again.

Mu Jinyu sighed and said helplessly, "I really earned them by doing tasks. I just had good luck and took on a task that wasn't too difficult but offered a lot of credits, so I earned over a thousand credits."

"Alright, what task was that?" the old mentor asked, unwilling to give up.

Mu Jinyu sighed again, not bothering to hide it any longer, and answered, "It was a task to encircle and kill a cultivator at the Second Layer of the Life and Death Realm, and I basically relied on myself to bombard that cultivator to death. So, are these thousand credits expensive?"

"Hmm?!"

The old mentor's eyes widened slightly at Mu Jinyu's words, "You killed a cultivator from the Life and Death Realm? That's impossible!"

"You're only at the Fourth Layer of the Void Breaking Realm! And you just broke through not long ago!"

His tone was full of disbelief.

Mu Jinyu glanced at the old mentor. He couldn't quite decipher his mentor's cultivation level, but it seemed to be somewhere between the Life and Death Realm and the Creation Realm.

Mu Jinyu said, "How about this, Mentor, you suppress your cultivation to the Second or Third Layer of the Life and Death Realm, don't use other means, and let's have a match. Then you'll know if it's true..."

In truth, he was too lazy to explain and prove himself.

If it were another mentor or the Institute Head, like Zhao Donglai and the others, he probably wouldn't care if they believed him or not.

But this old mentor was different. After all, he had borrowed credits from him before, and although he returned double the amount, he still felt indebted. Ignoring him entirely would be too cold-hearted.

So, he patiently explained more than necessary.

"Sure, let's try!"

The old mentor agreed, thinking that actions speak louder than words, and nodded with a smile.

"Hah!"

Then, they began their battle in the spacious hall.

The old mentor, being a powerful figure in the Creation Realm, though suppressing his cultivation to the Early Stage of the Life-and-Death Realm, had keen insight and experience, also understanding the Life and Death Law well.

So, when Mu Jinyu started fighting him, it was quite challenging.

He was completely suppressed, struggling to turn the tide.

In fact, fighting against him, Mu Jinyu was somewhat restrained, unable to use the Earth Emperor's Tome to suppress his cultivation or other tactics.

Unlike when facing ordinary cultivators in the Early or Middle Stage of the Life-and-Death Realm, in life-and-death combat, utilizing such methods made it much easier to ambush and kill opponents than facing the old mentor.

Yet, even so, Mu Jinyu eventually found an opportunity, unleashing the Life and Death Twin Dragon Fist, leaving the old mentor powerless to continue fighting.

"Cough, cough..."

The old mentor, severely injured, coughed lightly, blood clotted in his palm, yet his eyes were full of surprise, surpassing despair and dejection.

"Mentor, are you alright? I'm sorry, you're too strong, and my usual tactics didn't work, so I had to use my trump card."

Seeing the old mentor injured, Mu Jinyu hurried to support him, apologetically saying.

Indeed, if facing a typical Early Stage cultivator in the Life-and-Death Realm,

A single White Bone Sword Dragon Slash would have sufficed to blast them apart.

But just now, even employing the White Bone Sword Dragon Slash didn't affect the old mentor.

Finally, using the Life and Death Twin Dragon Fist, he managed to strike the opponent down.

"I'm fine, nothing serious!"

The old mentor waved off the concern, saying.

He looked at Mu Jinyu with appreciative eyes, despite coughing blood, "You're really something, defeating a Life-and-Death Realm me. I even felt, had you intended to kill me while I was suppressing my strength, I might truly have died under your fists..."

"Well, sorry, I didn't hold back, please don't mind..."

Mu Jinyu helped the mentor up and fed him a Healing Medicine, then assisted in accelerating the healing using Blood Essence.

"Hey, what kind of pill is this? It's so effective!"

The old mentor asked, surprised.

Mu Jinyu chuckled, "It's a secret formula, I won't say more."

"Alright." Seeing this, the old mentor didn't press further.

Mu Jinyu then took his leave, "Well, I've returned the credits, Mentor, I should head back. The advancement assessment is in a few days; I need to prepare more..."

"Alright, but I'm sure you'll advance to Senior Student!" the old mentor nodded.

Although he felt Mu Jinyu didn't need further preparation to stabilize his advancement, he didn't stop Mu Jinyu from preparing more if he wanted to.

After all, if Mu Jinyu faltered in the advancement selection, what face would he have to meet him?

So, the old mentor reluctantly watched Mu Jinyu leave.

Mu Jinyu wasn't lying about preparations. He truly had things to do.

After leaving the gravity training area, he headed directly for the Scripture Pavilion.

Although he intended to make breakthroughs reaching the Fifth Layer of the Void Breaking Realm through the Advanced Gravity Training Room,

But based on his past experiences, one more breakthrough to reach the Fifth Layer of the Void Breaking Realm, and the Advanced Gravity Training Room would become ineffective for him.

What to do then when he needs further training breakthroughs?

Should he really wander the world seeking a Super Gravity Training Room, then a Top-grade Gravity Training Room, and a Final-Level Gravity Training Room...

And then breakthrough to the Peak of Void Breaking Realm?

Not to mention whether the Canglan Realm has such terrifying gravity training rooms, even if they exist, entering rashly without the help of a top-grade expert would likely leave him dead and formless.

Therefore, he couldn't place all his hopes on the self-refined "Marrow Nourishment Chapter."

He prepared to read more scriptures and related classics, seeking alternative paths without such risky breakthroughs.

Instead, it allowed for gradual cultivation growth.

Soon, Mu Jinyu entered the Scripture Pavilion, heading straight to the last visited Human Race Classics Area.

The classics here were cheap to view and suited him perfectly, Mu Jinyu felt it was just right.

Upon entering the Human Race Classics Area, Mu Jinyu grabbed a book that required no academic credits and began reading silently, hoping to find some methods within.

Just as he became engrossed and gradually immersed, suddenly, he sensed something amiss with the atmosphere around him.

He turned abruptly, discovering behind him, at some unknown time, a long-haired figure with their face covered was standing behind, reading alongside him.

The sight sent shivers down his spine, and goosebumps crept up on him instantly.
