Starting as dockworkers, they swept through Chongqing.

Xilun found a huge old willow tree.

The dense shade of the trees and the drooping willow branches act as a natural barrier, enclosing this place into a private little space.

The ground was flat and covered with a thick layer of fallen leaves.

"This place is nice."

Xilun took a deep breath.

The air by the lake has a very high oxygen content. When you breathe it in, you feel a cool and refreshing sensation, which is much more comfortable than being in a training room filled with the smell of sweat.

There was no one around.

Xilun closed his eyes and composed himself.

Stand with your feet shoulder-width apart.

Its ten toes grip the ground, digging into the soil like tree roots.

With knees slightly bent, the spine slowly stretches, and the tailbone curls inward, as if to seal off the body's base.

Iron Wall Breathing Method.

"suck--"

Siren began to breathe in the same rhythm as Professor Ryan.

Inhale through your nose, the airflow is thin and even, as if trying to draw all the surrounding oxygen away.

The chest remained still, while the abdomen slowly swelled up, like an inflated ball.

As the airflow rushed in, a strange pressure began to accumulate within the body.

Although he hasn't developed a sense of qi during these few days at the club, his body has already formed muscle memory.

At this moment, on this quiet lakeside, my mind is at peace like never before.

There was only the sound of the wind, the sound of the water, and the sound of my own heartbeat.

"call--"

Exhale the stale air and your abdomen will contract.

Xilun felt as if his body had turned into a bellows.

Once, twice, ten times...

As time went by, that familiar soreness returned.

My thigh muscles were trembling, and my spine felt incredibly heavy, as if it were filled with lead.

Ryan's words echoed in my mind:

"Strength originates from flesh and blood, yet transcends flesh and blood."

"You need to imagine yourself as a blast furnace, and your breathing as the blower, squeezing out the energy from your flesh and blood and igniting it!"

press!

In this cruel world, who isn't being exploited?

Xilun gritted his teeth, veins bulging on his forehead, and increased the depth and frequency of his breathing.

Squeeze out every last bit of potential!

The high-calorie offal and fat we just ate now seemed to have turned into real fuel.

My stomach started to feel hot.

This heat flows through the blood vessels, washing away the fatigue in the muscles.

Just as Xilun was about to reach his limit, his legs could barely support him.

Sudden.

"boom!"

It was as if a muffled thunderclap echoed in my mind.

The subtle heat that was originally scattered throughout the limbs and bones suddenly converged towards the lower abdomen, as if drawn by some kind of magnetic field.

It was like a warm mouse that suddenly woke up three inches below its navel.

This heat rose from the lower abdomen, traveled up the spine, rushed past the coccyx, through the spine, and straight to the occipital bone!

Crackling sounds!

Guided by consciousness, this energy seeps into the subcutaneous layer through the pores, constantly tearing apart the originally loose epidermal structure, and expelling the dull dead skin and impurities like dust during exhalation.

His skin used to be rough and cracked from years of hardship, like dried parchment.

At this moment, after hundreds of breaths of breath-inducing refinement, a faint, translucent film of light began to flow across the surface of his skin.

When he stopped breathing and opened his eyes, his whole body looked as if it had been polished, his skin had the texture of alabaster, and it reflected a cold luster like jade or metal in the sunlight. Even mosquito bites could not leave any marks.

Xilun heard a series of popping sounds coming from inside his body.

The body, which was originally heavy, became incredibly light at this moment.

The soreness vanished instantly, replaced by an unprecedented feeling of fullness.

Become!

Xilun suddenly opened his eyes.

A captivating glint flashed deep within his pupils.

at the same time.

In front of his retina, in that crimson void visible only to him, a line of blurry writing began to distort, recombine, and eventually become clearly visible.

[Skill: Iron Wall Breathing Technique (Beginner)]

[Progress: 1/100]

【Characteristics: Initial energy generation, unblocking acupoints and meridians】

at last……

I've gotten the hang of it!

Xilun slowly finished, exhaling a long breath of white air.

The white vapor condensed and did not dissipate, shooting out half a meter into the air before slowly dissipating.

He looked down at the heat flowing through his body, pondered for a moment, and stood in front of the old willow tree.

He slowly clenched his right hand, and the heat that had just been generated in his body, which was darting around like a frightened mouse, traveled with great difficulty to his palm under the guidance of his mind.

It was a strange feeling, like holding an invisible, scorching hot hammer in your hand.

"drink!"

Xilun let out a low shout and slammed his right fist like a heavy hammer into the tree trunk.

The bark is rough, with years of accumulated dust between the grains.

boom!

A dull thud was heard.

The old willow tree trembled violently, and its withered yellow leaves fell in a rustling sound, as if a rain had fallen.

Xilun withdrew his fist, and saw that the hard bark of the tree where he had just struck had cracked open, revealing the pale white wood fibers inside, with a shallow fist mark on them.

"This is strength..."

Xilun looked at his fist; his knuckles were a little red, but it didn't hurt.

Enveloped in that heat, his fist seemed to turn into a hard iron stone.

An ordinary person throws a punch by contracting their muscles; but someone who has mastered breathing techniques relies on the breath they exhale.

As long as the energy remains, the strength will not be exhausted.

Xilun took a deep breath and assumed the posture for practicing breathing techniques once again.

He wanted to verify a hypothesis.

Breathe, practice, guide your energy.

That warm current surged again, though still weak, but a little smoother than the first time.

Xilun did not stop.

The third time, the fourth time, the fifth time...

Each time, that energy could be successfully channeled.

Although it is sometimes strong and sometimes weak, it always exists and has never disappeared.

Xilun stopped what he was doing, and with a thought, looked at the deep red panel in front of him.

[Skill: Iron Wall Breathing Technique (Beginner)]

[Progress: 6/100]

[Status: Stable Qi Sensation]

Looking at the number "6", Xilun's breathing became rapid.

His guess was correct.

One certificate for life, with a constant progress!

For the average person, learning breathing techniques is just the beginning.

As Renn said, even if you have mastered the feeling of Qi, you still need to practice frequently and not become rusty if you want to successfully guide Qi every time.

This is like fumbling for a light switch in the dark; an average person might press it ten times and only light up the bulb once.

As for Xilun, as long as you press it, the light will definitely turn on.

The progress bar will not rewind.

"As long as you practice, you will get feedback."

A glint of fanaticism flashed in Xilun's eyes.

With a strong liver, you can become stronger!

"One hundred times."

Silen silently calculated in his mind, "As long as I practice effectively for a hundred times, I can advance my breathing technique from the 'beginner' level to the next stage."

At his current pace, even excluding meals and sleep, he can practice more than twenty times a day.

In other words, it only takes five days.

Five days later, he will have mastered the breathing technique!

This speed is practically cheating.

It should be noted that among the thirty-odd students under Raine's tutelage, most of them had been practicing for half a year and still couldn't even grasp the basics of Qi sensation.

Even those four "geniuses" chosen by Renn took at least three months to go from beginner to proficient in using their strength.

"call……"

Xilun exhaled a breath of stale air, calming his excited emotions.

He glanced at the sky.

The sun had begun to set in the west, turning the lake surface a blood red.

Before I knew it, the afternoon had passed.

Xilun wiped the sweat from his brow and turned to walk back to the camp.

Now that you've already gotten started, there's no need to get stuck here.

The body has a limited capacity to withstand stress; excessive strain can damage its foundation.

Back at the lakeside campsite, the lively atmosphere had dissipated.

The charcoal fire had gone out, leaving only a pile of ashes.

Everyone is packing their things, preparing to return home.
