Regarding the departure of the old mentor.

Mu Jinyu, who was deeply immersed in cultivation, was not entirely unaware of it and vaguely knew something.

After all, both were cultivating in the same room, and he had to be cautious if the other suddenly lashed out?

But after the mentor chose to leave, the heavy stone gate fell once more, sealing the door completely.

With the drop of the stone gate, Mu Jinyu could finally retract the strand of vigilance outside and completely immerse himself in the intoxicating cultivation state.

And so, he quietly cultivated.

In the blink of an eye.

Four days had passed.

"Crunch, crunch..."

Accompanied by a slight sound of mechanisms turning, the terrifying gravity shrouding the cultivation room quietly dissolved.

"Hmm?!"

Sitting cross-legged on the ground with eyes tightly shut in cultivation, Mu Jinyu suddenly opened his eyes, which were full of frustration and displeasure.

Just a bit more!

He felt that in the four days of cultivation, he was just a step away from the Fourth Layer of the Void Breaking Realm.

Just a bit more, and he could have taken that step and successfully ascended to the Middle Stage of the Void Breaking Realm.

But right at this moment.

The twenty-four hour cultivation time was up.

Leaving him in a situation of neither here nor there, leading to total failure.

"Damn it, how can I be so unlucky!"

"Clearly, if I was given another hour, I could break through!!"

Mu Jinyu cursed in utmost frustration.

Then he thought of something, quickly jumped up from the ground, rushed to the activation slot at the door, and quickly turned to stop cultivation, allowing the door to open.

"Boom!!"

With Mu Jinyu's actions, the heavy stone gate slowly lifted upwards.

Before the stone door fully ascended and withdrew, Mu Jinyu bent down and squeezed out when it rose just half a meter.

"Mentor, mentor, mentor..."

He muttered anxiously, quickly turned a corner, found the old mentor sitting on a bamboo and rattan chair in the cultivation hall, eyes shining with excitement, and dashed over.

"What are you doing?"

Seeing Mu Jinyu appear, the old mentor still wanted to scrutinize whether he made any progress in cultivation?

But he saw Mu Jinyu staring at him eagerly, eyes longing, like a stray dog on the street seeing a piece of juicy meat, and he became alert, asking sternly.

"Mentor, I was so close to breaking through to the Middle Stage of the Void Breaking Realm. Would you kindly sponsor me one more hour of cultivation time, just enough to make it an even five hundred credits sponsorship..."

Mu Jinyu rushed over, holding the mentor's hand, speaking softly.

"Shoo, shoo, you tricked me once, and now you want to trick me again? You think I'm truly senile?"

The old mentor flung away Mu Jinyu's hand, speaking in an equally frustrated tone.

Hearing this, Mu Jinyu smiled sheepishly, knowing he could no longer sway the elder to sponsor him more than four hundred eighty credits; it wouldn't be easy to persuade him anymore.

So, he stopped asking for sponsorship, changed his tone, and said: "Well then, Mentor, could you lend me twenty credits first? I feel I'm about to break through, this feeling is fading, please help me? Afterwards, I can return forty credits to you!"

"Oh? Really?"

The old mentor's eyes lit up hearing Mu Jinyu's words, speaking quickly.

Honestly, when Mu Jinyu mentioned he was close to breaking through and asked to borrow twenty credits, he was already planning to help him.

Mu Jinyu then offered to repay forty credits; this came as a surprise.

He decided to take advantage of the situation.

Though twenty credits were far from making up for the lost four hundred and eighty credits.

He could deceive himself into thinking it balanced out; Mu Jinyu had taken some credits, and now Mu Jinyu would deliberately give credits back, making it even.

He wouldn't be that foolish anymore.

"Hmm, it is certainly true!"

Mu Jinyu quickly assured.

"Alright then, I'll trust you once more..."

The old mentor initially intended to ask Mu Jinyu for various assurances but thought it over; hadn't Mu Jinyu mentioned the feeling was fading?

What if delaying led to that breakthrough feeling disappearing, wouldn't it be my crime?

It would needlessly cause resentment from Mu Jinyu.

Thus, he didn't talk much.

After all, it was just twenty credits.

Even if deceived by Mu Jinyu, it wasn't a big deal.

So he directly took out his identity plaque, bumped it against Mu Jinyu's, and said: "There, transferred to you."

Mu Jinyu, hearing this, glanced at his identity plaque's marker, discovered he gained forty credits.

Did the elder transfer forty credits to him?

It seemed the mentor worried twenty credits might not be enough later, leading to a rush for more credits, thus missing the breakthrough opportunity, so he simply lent forty credits.

Mu Jinyu felt slightly warmed, smiled: "Alright, I'll repay you eighty credits then!"

With that said, Mu Jinyu dashed back to the Intermediate gravity training room.

"Hey, this kid..."

The old mentor heard Mu Jinyu's words, watching his hurried departure, couldn't help but smile.

Although Mu Jinyu promised to repay eighty credits, probably it was just beautifully said, unlikely he would genuinely repay that much, maybe used twenty credits, then returned twenty more before earning credits and repaying forty credits.

But regardless, even if just beautifully said, he felt joyful!

At least he had the intention too.

He could amuse me happily.

Shaking his head slightly, the old mentor stopped pondering, closed his eyes slightly, rocking on the rattan chair, descending into a drowsy state.

On Mu Jinyu's side.

After acquiring the needed credits, he rushed into the Intermediate gravity training room.

He then inserted the identity plaque into the activation slot and opened the activation switch.

"Boom!"

With the stone door closed, the room was once more enveloped in terrifying gravity.

But this time, although Mu Jinyu had not enhanced his cultivation, he was no longer as embarrassed as when he initially entered the Intermediate gravity training room, barely holding steady and almost being crushed by gravity!

Because, despite no breakthrough in cultivation over these four days, his entire body—every organ, every cell—under the pressure of gravity, reached a perfectly balanced cultivation state, significantly enhancing his overall strength.

Relying solely on physical strength, he could already cautiously battle against the gravity.

Then, Mu Jinyu closed his eyes again, commenced the cultivation method of the Marrow Nourishment Chapter, causing his internal organs to resonate, breath gradually entering that mystical rhythm.

With each breath, a small golden dragon appeared slowly at his nose and mouth.

Upon closer inspection, it was merely the Qi he exhaled.

In this slow cultivation state, time swiftly passed.

In the blink of eye, an hour went by.

"Boom!!"

After refining a substantial portion of the Space Law Fragment within, Mu Jinyu finally succeeded in advancing from the Third Layer to the Fourth Layer of the Void Breaking Realm!

Becoming an expert in the Middle Stage of the Void Breaking Realm!

"Swish!"

Mu Jinyu's eyes suddenly opened, sparkling with dazzling light, but the next moment, his gaze revealed a look of helpless frustration.
