Simultaneous transmigration, but with low martial arts and low magic.

Chapter 9: The Internal Energy System of Wuxia and the Breathing Technique System of Demon Slayer

Upon hearing Li Ke's words, Kai Yue looked up in astonishment.

"Sir, you mean...?"

Kaigaku was overjoyed, knowing that he would survive.

Although turning from a Demon Slayer into a demon is a disgrace to the Demon Slayer Corps.

But he didn't care about the honor of the Demon Slayer Corps, nor did he care what the Demon Slayer Corps thought.

Kaigaku is extremely arrogant and selfish, and only cares about whether he can live.

"Blood Demon Art: Parasite".

As the Blood Demon Art was unleashed, a tiny, wriggling bud appeared on Li Ke's finger, a sight that filled one with dread.

Seeing this, Kaigaku had a bad feeling, but he dared not resist.

He could only let Li Ke place the strange fleshy bud on his forehead and let it burrow into his head.

"ah!"……

The excruciating pain of the granulation tissue burrowing into his head caused Kaigaku to tremble in agony. When the pain reached its limit, he couldn't help but clutch his head and roll around in agony.

Finally, after rolling around for a few minutes, Kaigaku stopped moving and slowly stood up.

He touched his smooth forehead and, apart from a patch of blood, did not find the dent he had expected.

Clearly out of instinct to protect its host, the granulation tissue that burrowed into the head and completed its parasitic growth actively repaired the hole in Kaigaku's forehead, preventing Kaigaku from dying from excessive bleeding.

"This power!"

Feeling the power surging within his body, and a mysterious energy that he could mobilize, Kaigaku was immediately overjoyed.

"come over."

Upon hearing Li Ke's words, Kai Yue instinctively wanted to comply.

But in an instant, Kaigaku revealed a mocking smile, his right hand gripping the hilt of his Nichirin Blade, radiating killing intent.

Kaigaku is an extremely arrogant and selfish guy who will never truly submit to anyone.

Now I feel the powerful force surging within me, and I can feel the mysterious energy that I can control at will.

Kaigaku immediately felt a rebellious intent and wanted to turn against the person he had just sworn to serve for life.

"He really is an ungrateful wretch."

Lee Ke, who sensed Kaigaku's emotional state through his actions and the flesh buds, was not surprised.

Because in the original work, Kaigaku is such an unruly and ungrateful person, expecting him to be grateful is like hoping for an end to war.

Then Li Keyi had an idea.

"How is this possible?!"

Feeling that he could no longer control his body, Kaigaku revealed a look of fear in his eyes.

At this moment, he could no longer tremble with fear; his body remained firmly in place.

"You don't actually think I have no backup plan, do you?"

Hearing Li Ke's calm words, Kaiyue immediately begged for mercy:

"My lord, I was wrong. I only wanted to show you my newly acquired power."

"I absolutely had no intention of rebelling against you, sir. Please forgive me!"

As he spoke, Kaiyue inwardly wanted to slap himself repeatedly. What stupid thing had he done?

However, Li Ke ignored him and placed his hand directly on Kai Yue's shoulder.

Crimson internal energy surged forth and poured into Kaiyue's body, probing the condition inside his body.

It was discovered that the granulation tissue originated from the brain and grew along the body's meridians, at which point it had already occupied most of the twelve meridians within Kaiyue's body.

It is slowly growing into the eight extraordinary meridians, twelve divergent meridians, fifteen collateral meridians, twelve muscle meridians, and twelve cutaneous regions.

It's just that when Li Ke used the Blood Demon Art: Parasite, the concentration of demon blood he gave to this bud wasn't very high.

This granulation tissue naturally cannot grow fully and directly occupy the positions of all the meridians in the human body, connecting them from top to bottom.

"No wonder I could sense your internal energy."

Li Ke said, somewhat as if he had just realized something.

He didn't know whether the humans in this world could cultivate internal energy by practicing the internal energy cultivation methods of the Condor Heroes world.

After all, the Demon Slayer world and the Condor Heroes world are completely different worlds, and the rules of the two worlds may have slight differences.

However, regardless of the circumstances, it is a fact that he did possess internal energy after synchronizing with the gray fog space.

Given his special circumstances, it's quite normal for Kaigaku to be able to gain internal energy through the flesh buds.

"Is this powerful, mysterious energy called internal force? A very nice name!"

As he spoke, a glint of ambition flashed in Kaigaku's eyes.

The Thunder Breathing Technique he mastered essentially enhances the body's cardiopulmonary capacity and blood oxygen-carrying efficiency by inhaling a large amount of air.

This, in turn, increases muscle strength, nerve reaction speed, and wound healing ability, but in essence, it is still the strength of the physical body itself.

The so-called "constantly focused breathing" simply means maintaining the breathing technique while walking, sitting, lying down, or even sleeping.

This subtly transforms the body, making it stronger and stronger.

Therefore, the longer one concentrates on mastering the Thunder Breathing Technique, the stronger one's physical strength and overall power will become.

Ultimately, as people age, their physical abilities decline due to aging.

However, the energy within the body called internal force is a real and genuine supernatural energy.

It wasn't a technique like the Thunder Breathing Method that simply strengthened the body, which naturally fueled Kaigaku's immense ambition.

He harbored a burning ambition to rely on this magical inner strength to forge a great career.

However, Kaiyue dared not show it. In front of Li Ke, he remained as obedient as a quail and dared not harbor any rebellious thoughts again.

He dared not harbor any rebellious thoughts until he found a way to overcome the ease with which Li Ke could control his body.

"Next, I want you to teach me the Thunder Breathing Technique and its accompanying sword skills."

"To teach you, sir, the Thunder Breathing Technique and its accompanying sword skills?!"

Kaigaku's eyes widened in disbelief.

Simply because compared to internal energy, this magical supernatural power.

In Kaigaku's eyes, everything, whether it was the Thunder Breathing Technique or anything else, was utterly weak.

At this moment, this person actually wants to learn the Thunder Breathing Technique and its accompanying sword skills. Isn't this like throwing away the watermelon to pick up a sesame seed?

However, Li Ke was not stupid, because he knew that the breathing techniques in Demon Slayer were not as bad as Kaigaku thought.

For example, when Tanjiro was undergoing special training under Sakonji Urokodaki, the large rock that Tanjiro had to cut to graduate was a testament to his skill.

That huge rock was 2.5 meters wide and 2 meters high, weighing at least 5 tons, yet Tanjiro managed to cut it in half with a single stroke.

Even Hao Datong, the master of the martial arts novelist Li Ke and the most skilled swordsman among the Seven Masters of Quanzhen, couldn't cut such a huge rock in half with a single sword strike.

But Tanjiro did it, and not only Tanjiro could do it, but the other Pillars could do it too.

From this point of view alone, the breathing techniques and sword skills of the Demon Slayer world have their own unique features.
