In Martial Universe, Signed in at the Start with Yao Lao's Ring

Of course, Lin Yan did not continue teasing Little Marten.

At this moment, seeing that Little Marten had already softened up and restrained his arrogant attitude, Lin Yan did not press him further.

With a flick of his finger, he directly sent the prepared pill into Little Marten's hands.

Little Marten caught the pill with one hand and immediately stuffed it into his mouth. After a brief chew, he swallowed it completely.

Instantly, a powerful medicinal force surged within Little Marten's body.

"What potent medicinal power!"

Little Marten's eyes lit up, and without hesitation, his Heavenly Demonic Marten physique activated, quickly absorbing the energy. His previously weak aura began to strengthen.

"Lin Yan, you've won me over! Grandfather Marten is making you my friend!"

"If you get more of these in the future, bring them to Grandfather Marten!"

"When Grandfather Marten recovers his strength, you'll be well rewarded!"

Little Marten pounded his chest confidently while speaking to Lin Yan.

Lin Yan simply chuckled and didn't say much.

After all, he understood Little Marten's personality very well. This guy was the epitome of arrogance.

Even if he wanted to express his gratitude, his eccentric personality wouldn't allow him to say the words directly. Instead, he would repay the favor in his own way.

So, Lin Yan considered this to be Little Marten's way of acknowledging his goodwill.

Little Marten then turned his gaze toward Lin Dong and suggested, "Since we're already here, why not take Lin Yan to try out your Mind Millstone?"

"Although it's painful, it's incredibly effective for training mental energy."

Lin Dong nodded in agreement.

He then looked at Lin Yan. "Want to give it a try?"

Lin Yan nodded. He was indeed quite curious about what the Mind Millstone experience felt like.

"Alright! Let's give it a try."

Seeing Lin Yan's willingness, Lin Dong immediately took the lead, guiding Lin Yan and Little Marten toward the Mind Millstone.

On the way, Lin Dong briefly explained the principles behind it.

Simply put, the Mind Millstone involved throwing Lin Yan's mental energy construct into the grinding mechanism, where it would be repeatedly crushed and rebuilt. This cycle of destruction and rebirth would rapidly enhance his mental energy.

However, due to this extreme process, the pain experienced during the grinding was excruciating.

"To be honest, the pain is quite terrifying," Lin Dong admitted, recalling how he had nearly passed out from the experience.

Little Marten casually added, "Grandfather Marten tried it once long ago, and after that, I never wanted to do it again. So if you feel like you can't handle it, just consider it a test run and stop when needed."

Hearing this, Lin Yan's curiosity only grew. He turned to Lin Dong and asked, "How many cycles did you last?"

Lin Dong smiled. "Ten cycles."

It was clear that he was very satisfied with his first attempt. Even Little Marten had acknowledged his endurance.

"Ten cycles, huh?"

"Alright, I'll give it a try too."

Lin Yan smiled as he spoke.

Soon, under Lin Dong's guidance, they arrived at the Mind Millstone.

Since Lin Dong had yet to fully recover his mental energy, he wasn't planning to train with the millstone this time.

Instead, he and Little Marten stood aside to watch Lin Yan's attempt.

"Alright, here I go."

Lin Yan wasted no time.

The moment he stepped into the millstone's grinding mechanism, an overwhelming force enveloped him.

Lin Yan instantly lost control of his body.

Under the terrifying pressure of the millstone, his body began to break apart inch by inch, and an unbearable pain surged through him.

It hurt. The pain was indescribable!

Only after experiencing it firsthand did Lin Yan finally understand why even Little Marten had refused to use it a second time.

Although it indeed brought a massive boost to mental energy, the pain was simply beyond reason.

However, Lin Yan had always possessed immense willpower.

While the initial grinding nearly made him wish for death, as time passed, he adapted to the pain.

Eventually, he became numb to it, and the excruciating agony faded into the background.

Outside the Mind Millstone

Little Marten and Lin Dong had been watching Lin Yan undergo the Mind Millstone grinding process.

However, the more they observed, the more shocked they became.

Gradually, they realized that the number of grindings Lin Yan had endured had already far exceeded normal limits. Yet, inside the millstone, he still didn't appear to have reached his limit.

"Twelve times..."

"Fifteen times..."

"Twenty times..."

"Damn! This guy is a total freak!"

Little Marten had originally thought Lin Yan would be like him—try it once and never want to use this torturous training method again.

But he had completely underestimated Lin Yan. He had already endured twenty grindings and was still continuing.

At this point, Little Marten couldn't help but twitch his mouth and curse out loud.

"I can only say… that's Lin Yan for you," Lin Dong chuckled bitterly.

He had initially thought his record of ten rounds was already insane.

But Lin Yan took it to another level—doubling his record and still showing no signs of stopping.

They continued watching as Lin Yan underwent the grinding process.

"Twenty-two times."

"Twenty-five times."

"Twenty-seven times."

Finally, after reaching twenty-seven rounds, Lin Yan showed signs of struggling and decided to stop.

At this moment, both Lin Dong and Little Marten were completely dumbfounded, looking at Lin Yan as if they had just witnessed a monster in human form.

"Unbelievable! Absolutely insane!"

Lin Dong and Little Marten couldn't hold back their exclamations.

Lin Yan, however, immediately took a pill to recover.

As soon as the pill entered his mouth, his complexion visibly improved. A quick internal check confirmed that his mental energy had significantly increased.

He decided that he would continue this training in the future whenever he had the time.

Even though the process was painful, the clear and tangible results made the suffering worthwhile.

In fact, he even felt a strange kind of exhilaration in the self-torture aspect of the training.

Of course, Lin Dong and Little Marten could not comprehend his mindset at all.

Especially after learning that Lin Yan found the process somewhat exhilarating, their gazes toward him became even more bizarre.

"Damn… this guy is a total maniac!"

Naturally, Lin Yan did not continue training that same day.

After exiting the mysterious space, he accompanied Lin Dong to eat.

For the next few days, whenever he fully recovered using pills, he would enter the mysterious space to train with the Mind Millstone.

As he continued to push himself, the number of rounds he could endure increased, leaving both Lin Dong and Little Marten even more dumbfounded.

That day, Lin Yan had originally planned to resume his training with the Mind Millstone.

However, just as he stepped out, a loud voice rang across the Lin Family estate.

"Blood Cloth Sect at the gates! Lin Family, come out and meet your death!"

Hearing this, Lin Yan's brows furrowed. He immediately unleashed his mental energy, scanning the area outside the Lin estate. As expected, a large force of Blood Cloth Sect members had arrived, surrounding the Lin Family estate completely.

The voice just now had come from them.

Lin Yan's expression instantly turned ice-cold.

"As expected… the Blood Cloth Sect has arrived!"
