"Very well, this is what you call marrow nourishing!"

Mu Jinyu felt the breakthrough in his cultivation, his entire body's strength growing, yet without that insatiable hunger, he couldn't help but marvel in his heart.

He was now certain that he hadn't strayed from his path; this truly counted as the genuine Marrow Nourishment Chapter cultivation method.

Then, Mu Jinyu stopped overthinking and immersed himself in this incredibly wonderful state of cultivation.

A small white stream of Qi moved between his nose and mouth, his chest rising and falling, while his entire body surged with dazzling divine light, as if he were bathing in the morning glow.

In this selfless state of cultivation, two hours passed in the blink of an eye.

"Crack, crack!"

A sudden mechanical clicking sound came from the Intermediate gravity training room, and the overwhelming gravity vanished abruptly.

This immediately drew Mu Jinyu out of the wonderful cultivation state.

"Did it end so soon?"

"It felt like only a few minutes had passed..." 𝚏𝗿𝗲𝐞𝚠𝕖𝐛𝗻𝗼𝐯𝕖𝚕.𝚌𝗼𝗺

Mu Jinyu whispered in a somewhat disappointed tone.

Then he got up and walked to the activation slot of the cultivation room, where he saw his identity plaque in the slot, displaying only three remaining academic credits.

If he were in the Beginner gravity training room, he could have cultivated for another hour.

But in the Intermediate gravity training room, three credits weren't even enough for an hour.

"With my current physical condition, the Intermediate gravity training room is still useful for me. I can't just leave it at that; I need to quickly earn credits and continue cultivating!"

Mu Jinyu muttered to himself as he pulled out the identity plaque from the activation slot and quickly walked out of the Intermediate gravity training room.

After rounding a corner, he entered the outer hall.

The old mentor, lounging on a wicker chair, saw Mu Jinyu appear, a glint of astonishment in his eyes, and said, "Young man, why are you out so quickly? Could you not take it?"

He thought Mu Jinyu might have struggled to handle the Intermediate gravity training room.

This assumption was quite normal.

After all, in Dongyue Mansion, there weren't many mentors or institute heads who could endure the Intermediate gravity training room.

And Mu Jinyu was just a student, though he was currently refining his flesh, claiming he could endure long periods in the Intermediate gravity training room seemed unrealistic.

In fact, this mentor even speculated that Mu Jinyu had likely been unable to endure for a while but couldn't stop since he had activated it, so he had probably suffered inside for quite some time.

Thinking of this, he couldn't help but chuckle to himself.

Mu Jinyu was unaware of the other's thoughts and shook his head, "No, I still want to continue cultivating, but I ran out of credits, so I have to go earn more credits before coming back to cultivate."

"No worries, don't get discouraged. In all of Dongyue Mansion, those who can endure in the Intermediate gravity training room for two hours are few and far between — counting me, there are only about five. For someone as young as you, just a student, being able to last for an hour is pretty remarkable..."

Without clearly listening to Mu Jinyu, the elderly mentor began to comfort him of his own accord.

He even intended to boast that he too could endure in the Intermediate gravity training room for two hours.

But before he could finish, he quickly came to a realization.

He stared wide-eyed at Mu Jinyu, his clouded elderly eyes filled with shock and disbelief, "What? Did you say you could continue, but you just ran out of credits?"

Speaking thus, he looked Mu Jinyu up and down, the latter's slight and non-muscular frame, shaking his head vigorously, "I don't believe you!"

"Then don't believe it!"

Mu Jinyu couldn't be bothered to explain further.

He prepared to leave directly, not caring about the other.

But then, considering the person might be the mentor in charge of the gravity training room, and he wasn't sure if he might encounter obstacles from him,

Mu Jinyu softened his tone a bit, "I'm leaving first, I'll come back once I've earned enough credits."

"Hey, wait a moment..."

As Mu Jinyu was about to leave, the old mentor called out to him.

At the same time, his body moved, springing from the rocking bamboo wicker chair and landing in front of Mu Jinyu, blocking his path.

"What is it?"

Being blocked, Mu Jinyu felt rather annoyed.

After all, he was planning to quickly earn a few hundred credits and then practice well in the Intermediate gravity training room.

No time to be tangled up proving he could endure long periods in the room.

So, Mu Jinyu's tone turned slightly impatient and wasn't as polite.

The old mentor clearly didn't mind Mu Jinyu's tone, hastily asking, "You mean you could keep practicing in the Intermediate gravity training room, but you ran out of credits, so you have to earn more?"

"Isn't it okay now? I couldn't bear it and want to leave; is that alright?"

Mu Jinyu directly shifted his words, conceding.

Still, this time, the old mentor wasn't planning on letting him leave. Hearing Mu Jinyu's impatient response, he realized the young man wanted to quickly dismiss him, so he wasn't angry.

He looked seriously at Mu Jinyu, noticing no signs of injury on him.

And he had indeed heard the Intermediate gravity training room activate, suggesting Mu Jinyu had truly cultivated there for an hour unharmed?

"If you're short of credits, I have some. I can lend you 160 credits for eight hours of practice in the Intermediate gravity training room. How about you go back and show me?"

The old mentor suddenly said.

"Hmm?!"

Originally impatient, Mu Jinyu's eyes narrowed upon hearing this, concealing the flash of excitement in them.

Then he looked at the old mentor, frowning, "Are you serious?"

"Yes," the old mentor nodded, "So, are you up for it?"

Mu Jinyu shook his head, "I wouldn't dare!"

"Then why the nonsense?" the old mentor, hearing Mu Jinyu, vented his irritation sarcastically.

Mu Jinyu shook his head, "Eight hours is too little. How about at least twenty-four hours?"

The old mentor, hearing him, lost his irritation, replaced by a peculiar look, "Twenty-four hours, you have quite an appetite!"

An hour in the Intermediate gravity training room requires ten academic credits, so twenty-four hours would cost 480 credits!

Close to five hundred credits!

The reward for an Intermediate student ranked between fifty and a hundred for five months!

And after deducting the fifty credits accommodation fee Intermediate students have each month, it would take ten months of saving to accumulate.

Mu Jinyu requested such a large number of credits right away, which was indeed a sizable appetite!

"So, do you dare?"

Mu Jinyu asked the old mentor.

The situation suddenly reversed; just now, the old mentor was questioning Mu Jinyu's bravery.

Yet in an instant, it was Mu Jinyu questioning him if he dared provide that many credits.

The old mentor stared at Mu Jinyu with a suspicious look, hesitated, "I dare!"

Then, after a pause, he added, "But there's a condition. These twenty-four hours of credits must solely be used in the Intermediate gravity training room and must be used up within twenty-four hours, not stretched out over years..."

"And you can't activate the room and leave it on, wasting my credits..."

"Would you agree to that?"
