Fox Demon: Heaven rewards diligence; I will eventually achieve divine mastery of martial arts.

Lin Yu said casually, enduring the pain as he continued practicing his boxing.

As someone who grew up in a peaceful era, it's impossible to say that yesterday's street murder had no impact on him at all.

Thinking about what happened yesterday, Lin Yu realized that his sense of crisis was still not strong enough.

I woke up in the middle of the night and immediately got up to start practicing boxing.

He was just a short distance from breaking through the Mighty Bull Technique.

I've been practicing since midnight, and I'm finally close to a breakthrough.

It's unclear what will happen after the Mighty Bull Technique, which has already reached its limit, breaks through its limits.

But now, this is the only thing that can bring Lin Yu help and a sense of security.

"Oh."

Feng Qi responded and went to the kitchen to begin her daily washing and grooming, but her eyes remained fixed on Lin Yu.

As Lin Yu pounded his fists on the wooden stake, the notification sound kept ringing in his ears.

[You have diligently practiced the Mighty Bull Kung Fu and gained some insights; proficiency +2!]

Lin Yu stared at his system panel, where the proficiency level of the Mighty Bull Technique was steadily increasing.

Mighty Bull Technique LV.2 (497/500)

Mighty Bull Technique LV.2 (498/500)

Mighty Bull Technique LV.2 (499/500)

Mighty Bull Technique LV.2 (500/500)

[The Mighty Bull Technique has been upgraded to LV.3 (0/1000), and your understanding of the Mighty Bull Technique has increased.]

With the upgrade notification, a lot of insights into cultivation suddenly flooded my mind, including how to exert force most quickly and effectively.

It's as if after years of diligent study and practice, it's natural and effortless.

The heat that had appeared before surged through my body once again.

This time, however, it will come even more fiercely and powerfully.

A torrent of heat, like a flash flood, washed over his entire body.

(End of this chapter)

Chapter 12: An Astonishing Improvement From the Outside In

Every inch of skin, every inch of muscle, every inch of bone.

As the heat spread throughout his body, a slight pain also began to emanate from him.

These heat streams spread out like ants, tearing apart the body's muscle fibers one by one, only to have them regenerate and heal.

The tearing pain almost made Lin Yu cry out in agony for a moment.

Fortunately, he reacted quickly, clenching his teeth tightly and not making a sound.

However, the skin exposed on the body surface began to turn bright red during the process of the muscle fibers being torn and then regenerated.

My heart raced and my body temperature spiked.

At this moment, if Feng Qi were to come over and lift up Lin Yu's clothes, she would surely find that his entire body was as red as a crayfish.

Snowflakes landed on me and melted instantly.

Beneath the skin, there were bulges that looked like small snakes, constantly writhing.

It was as if some unknown and eerie thing was lurking within his body.

The pain intensified over time.

Feng Qi, who had already finished washing up and was eating breakfast, seemed to sense something and looked in Lin Yu's direction.

When he saw that the exposed skin on his body had turned bright red, he paused in his movements, his eyes filled with confusion and doubt.

The next second, she appeared behind Lin Yu, the soup in her hand not causing a ripple. She frowned and reached out to grab Lin Yu's neck, wanting to check the situation.

Just as her hand was about to touch Lin Yu's skin, a sigh of relief rang out.

"call!"

After feeling the heat in his body completely dissipate and disappear, Lin Yu finally breathed a sigh of relief.

This feeling is completely different from the last time, and it's really torturous.

The pain was so terrifying that even fainting was a luxury.

Every muscle seemed to have malfunctioned, and he couldn't even control his entire body; he wanted to scream but couldn't make a sound.

"Before, I always read novels about how painful the process of advancement was, how it felt like ants were crawling inside your bones, or like being burned in a raging fire. I never imagined I would experience it myself."

Lin Yu wiped the sweat from his forehead and realized that his clothes were already soaked with sweat.

It's stuck to my body right now, sticky and uncomfortable.

However, what Lin Yu cared about even more was the change in his own body.

Last time, the biggest boost from the heat flow, besides increasing his own strength, was the toughness of his skin.

While it's not quite capable of withstanding sharp blades yet, its resistance to blows has improved considerably.

So what about this time?

During the previous strengthening session, Lin Yu clearly felt that the target of this heat flow was his muscles.

Looking down at his hands, which seemed to have changed little, Lin Yu resisted the urge to experiment here.

Last time Feng Qi saw it, I barely managed to brush it off, but if he sees it again, it's hard to say.

Thinking of this, Lin Yu turned his head, intending to check if Feng Qi had finished eating, as he was about to boil some water for a bath.

Then I saw a delicate face appear before my eyes.

So close, Lin Yu could even feel the warm, faintly fragrant breath brushing against his face.

"!!!!!!"

"How come you walk so quietly?!"

The sudden approach startled Lin Yu.

"Were you feeling unwell just now?"

Feng Qi ignored Lin Yu's words, but frowned and stared at him, especially at the skin on his neck.

"No, it's just that I suddenly had some inspiration while practicing just now, so I thought about it."

"Your skin is all red."

"It's so hot. I've been training for too long today, and my clothes are all soaked with sweat. I was just about to go take a shower."

Lin Yu casually tried to cover it up, tugging at his collar as a wisp of steam rose up.

Feng Qi stared at Lin Yu for a long time, but couldn't figure out anything.

She took her bowl back to the kitchen and quietly went to eat.

Seeing that he had glossed over the matter, Lin Yu reminded himself that next time he needed to break through, he would definitely need to find a safe and secure place.

I boiled some water and went to the side room to pour it into a wooden bucket.

Lin Yu took off his clothes and stood in the room.

Unlike when he first came into this world, his originally ordinary body has now become strong and muscular.

On that naked body, the sharply defined muscle lines flowed incredibly smoothly.

At first glance, it looks like a masterpiece created by the world's most skilled sculptor.

The golden ratio division makes everything look so beautiful.

'Just as I thought.'

Lin Yu looked at his muscles and thought to himself.

After being strengthened by the heat flow, I became much stronger.

The power contained within his body was incomparable to anything he had ever possessed before.

Lin Yu glanced around, picked up a piece of discarded brick from the corner, and casually tapped it lightly. With a crisp sound, the brick broke.

He clenched his fist slightly, and the veins on his arm bulged.

A surge of power coursed through his body.

Lin Yu looked at the earthen wall in front of him, slowly exhaled a breath of stale air, and his scabbed fist pressed against the wall, causing a slight vibration.

'His strength has increased considerably again; if he were to unleash a full punch, breaking through this earthen wall would be no problem at all.'

Looking at the shallow fist mark left on the wall, Lin Yu gained a deeper understanding of his current strength.

'Not only that, my reaction time and speed have also improved significantly.'

'The limit of the Mighty Bull Technique is the second level, where the outer skin becomes tough and the strength increases.'
