Where's my golden core? Did you think I removed a kidney stone?

Su Ye gave Li Tong a few more instructions, repeatedly explaining the rhythm of breathing, how to deal with an attack, and the importance of never using medication indiscriminately. Finally, he told Li Tong to go back and study it on his own.

Before leaving, Li Tong still looked both respectful and fearful, standing at the door, clutching his phone as if it were a lifeline.

The two also exchanged contact information.

This way, it will be easier to contact them later.

The ward door closed.

The room fell silent.

Su Ye leaned back, casually flipped the book on the table over, and placed it directly on his face. He sank into the old rocking chair, which creaked and groaned as if it were helping him organize his thoughts.

In his mind, the changes that had just occurred within Li Tong's body were replaying in his mind.

Just as he expected.

Once the heart begins to change, it doesn't just bring about a change in a single point, but rather an improvement in the whole person. The heart fire resonates, bringing with it blood, breath, and all the limbs and bones. Strength will be greater, and breath will be longer. The body is as if it is being propelled by an invisible engine, and the whole person will be elevated to a higher level.

The heart, indeed, is the engine of spiritual energy.

This idea was initially just Su Ye's own guess, but now, Li Tong's situation has gradually verified this guess.

Thinking of this, Su Ye's lips curled up slightly.

Interesting.

In the shadows of this city, the scattered "evolvers" are like special problems, and he happens to be the one best suited to solve them. The mental enhancement brought by the water-based golden core allows him to see things more clearly, reason faster, and extract the true patterns from scattered appearances.

He liked this feeling.

It was as if the times had laid out a test paper in front of him, and he was sitting in the front row, head down, solving the problems.

However, the more Su Ye tried to understand, the clearer the outline in front of him became.

Li Yuefeng and Li Tong are clearly not the same person.

Li Yuefeng's changes are reflected in his limbs, muscles, and localized power techniques. It's like a "skill" that has evolved from his own flesh and blood. In the end, it's a kind of "local" evolution. It's impressive and fierce, but it hasn't truly touched the root of life's evolution.

Li Tong, however, was different.

His change was felt in his heart.

It falls at the level of the five internal organs.

That's a deeper level of change, and it brings you closer to yourself.

Otherwise, Su Ye wouldn't have immediately mistaken his condition for a nascent fire elemental form about to crystallize at the marathon.

However, Li Tong was ultimately one step behind him.

There's fire in his heart.

But no crystals formed.

Thinking of this, Su Ye slowly removed the book from his face, sat up straighter, and his eyes gradually brightened.

"It now seems that localized evolution is just a minor path."

"The next level up is people like Li Tong, whose evolution points are located in the internal organs."

"And further up..."

He raised his hand and pressed his left waist.

The water-based golden elixir rested there quietly, like a tranquil spring.

"This is the formation of crystallization, the prototype of the Golden Core."

Su Ye nodded.

I already have a general idea in mind.

He picked up the notebook, turned to a blank page, and wrote down his deductions.

The kidneys belong to water, the heart to fire, the lungs to metal, the liver to wood, and the spleen to earth.

Metal, wood, water, fire, and earth are the five elements.

The transformation of the Five Elements, manifesting as inner visions, is what makes people like Li Tong.

The inner realm of elixir formation is what I am capable of.

As he wrote this, Su Ye suddenly smiled.

I understand now.

At least some of the chaotic mist in front of him had been dispersed by him.

The previously scattered and disorganized clues have finally been connected by a single thread. Although it is not yet complete and there are still many parts that are not clear, it is much better than the initial state of complete ignorance.

It's a sense of understanding that's hard to describe.

It's like someone groping in a thick fog for a long time, finally standing on a slightly higher place, where they can see a few steps ahead.

This is enough.

Take it one step at a time, and you'll eventually make it through.

Su Ye sat in the rocking chair, his mind gradually calming down.

The breath naturally sinks down.

call.

suck.

At that very moment, he suddenly realized that his breathing technique had changed slightly.

It wasn't a change that was deliberately deduced, but rather an improvement that came naturally. It was as if, after sorting out those layers of evolutionary pathways, one's mind became clear as well. As a result, the flow of energy became smooth, and the rhythm that could only draw a dozen or so strands of spiritual energy suddenly seemed to have opened some kind of key.

next second.

Suddenly, all the spiritual energy that was originally as fine as a wisp of silk surged toward him.

A wisp.

Two strands.

Three strands.

……

Twenty strands.

Twenty strands of spiritual energy followed his breath, like a silent drizzle, which he swallowed into his body one sip at a time.

Su Ye's expression changed instantly.

Another step forward in breathing techniques!

He dared not be careless and quickly calmed his mind, guiding the twenty strands of spiritual energy to flow slowly along the meridians that had already formed in his body. The moment the spiritual energy entered his body, it did not immediately bring a stinging pain. Instead, a warm current slowly spread from his chest and abdomen.

Followed by.

boom!

Su Ye's heart skipped a beat.

That familiar yet strange feeling has returned!

A warm current exploded from his heart, then swept through his entire body like a warm tide. His skin tightened, his bones tingled, and it felt as if countless tiny impurities deep within his flesh were being violently washed away. A mixture of sensations—soreness, itching, swelling, and heat—almost made Su Ye jump right out of his chair.

His eyes flickered slightly.

At this moment, he could clearly feel his skin being washed again. The already warm and resilient skin membrane became tighter, finer, and had a jade-like texture. It was as if tiny impurities were being squeezed out from deep within the pores, and a layer of light gray-black sweat even floated on the surface of his arm, carrying a faint fishy smell.

And the spiritual energy meridian within his body suddenly lit up under this round of cleansing.

It was originally just a thin strip.

Now it resembles a riverbed that has been eroded by the river, with clearer edges and a more spacious interior, allowing spiritual energy to flow through it much more smoothly.

Even their strength is increasing.

Su Ye subconsciously clenched his fist, and a series of subtle cracking sounds came from the squeezing of his knuckles. In the instant his arm muscles tensed, he had a strange feeling that he could punch through a wall.

"This is……"

Su Ye's pupils dilated slightly.

He wasn't unaware that cultivation would bring about changes.

But this time, the change was too obvious.

Skin, meridians, and strength all improved simultaneously.

And that feeling...

so similar.

It felt just like that day on the mountain, when I was sitting cross-legged next to the stone statue, and my whole body was being repeatedly washed by a warm current.

Cleansing the essence and marrow.

Su Ye's Adam's apple bobbed, and he felt a surge of heat in his heart.

"Marrow cleansing".

He whispered those two words.

This is the second time the marrow has been cleansed!
