People in Demon Slayer: The Journey That Began with Demon Slayer

A violent earthquake struck the island, followed by a black beam of light shooting into the sky, which then rapidly spread outwards, annihilating everything in its path.

The immense power caused the once calm sea to surge and churn, creating a gigantic tsunami that seemed poised to swallow the sky and blot out the sun.

Yekura and Jugo stared in disbelief at the scene before them, which seemed like a divine punishment.

The approaching tsunami caused Yekura and Jugo to abandon the ship, which was in danger of being destroyed at any moment, and choose to stand on the sea surface with their chakra to deal with the tsunami.

The tsunami caused a light rain to fall from the sky.

"Wind Release: Wind Slice Technique!"

Yekura transformed the wind into sharp blades, attempting to cut a gash in the tsunami.

However, when faced with natural disasters, Yekura's ninjutsu appeared extremely insignificant and powerless.

Yekura solemnly warned, "Jugo, be prepared, don't drown!"

Before Jugo could understand what Yokura meant, he saw Yokura begin to form hand seals.

"Wind Release: Tornado Hurricane!"

A tornado appeared beneath Yekura and Jugo's feet, continuously blowing them into the sky until they reached a height exceeding that of a tsunami.

The tsunami roared away, destroying the tornado in Yekura.

However, this allowed Yekura and Jugo to successfully avoid the tsunami, falling freely from the sky into the sea.

The two emerged from the sea and looked in the direction of Yosuke.

Yosuke remained in the same position, suspended in mid-air.

The island beneath their feet had completely vanished, becoming part of the sea.

Yosuke's consciousness was unaware of what his physical body had done and still believed he was in a cave on the island.

Yosuke pondered a solution, while the illusion of Kibuyaku Muzan continued to tempt him relentlessly.

This kind of natural energy is too unfamiliar to Yosuke so far, since he has only seen it in Jugo and Jiraiya.

However, why was Jiraiya able to control natural energy?

Yosuke began to recall the details of when Jiraiya defended against Deidara's clay bomb in Konoha.

Yosuke vaguely remembered that Jiraiya's face had developed strange markings, and his nose had become very large, with many toad-like spots on it.

In other words, Jiraiya used some means to gain control over natural energy.

So how did Jiraiya control it...?

Yosuke subconsciously thought of chakra.

All ninjas are inseparable from chakra; one could say that chakra is the essence of a ninja.

Chakra is a product of the balanced mixing of one's spiritual energy and physical energy.

Since it is a product of chakra mixing, is it possible to stabilize it by mixing in natural energy as well?

Having no other option, Yosuke could only begin to experiment.

Yang Jie began to mix his spiritual energy, physical energy, and natural energy.

However, no matter how hard Yosuke tried, the natural energy was too violent to be mixed at all.

When natural energy is mixed in, it will instantly devour both spiritual and physical energy.

Yang Jie was once again in a predicament.

Chapter 262 Demon Transformation Immortal Mode

Yang Jie was struggling with how to combine natural energy and chakra.

Meanwhile, Kibuyaku Muzan's seductive voice gradually eroded Yosuke's patience.

His mindset changed again, causing Yosuke's demon horn to gather power once more, and the black sphere reappeared.

To avoid being accidentally injured, Yekura and Jugo landed on a nearby small island and observed Yosuke's movements from a distance.

Yekura asked Jugo with alarm, "Jugo, when you completely lose control, is the damage you cause really this great?"

Jugo shook his head and smiled bitterly, "How could that be? My best achievement when I lost control was defeating Orochimaru's five subordinates besides Kimimaro. Those four were all skilled in using cursed seals and possessed the strength of Jonin. That was my limit."

Jugo looked at the island that Yosuke had destroyed and trembled with fear: "I can't even imagine the destructive power that Yosuke-sama has."

At this moment, within Yosuke's consciousness, Kibuyaku Muzan was mocking Yosuke.

"Why do you want to master such useless power, Yosuke Ubuyashiki? You're a demon! How can you, a demon, want to master human power? You don't think that mastering human power will make you human, do you?"

"Ubuyashiki Yosuke, don't you have the human-transforming drug? Since you want to become human, then inject yourself with the human-transforming drug. In the end, you are proud of your identity as the Demon King, and deep down you still believe that demons and humans are two different kinds of beings."

Yosuke, who was already irritable, became even more furious. He was about to refute Kibuy Muzan when he suddenly stopped.

Yosuke was inspired by the selfless and ruthless words of the demon.

The power of demons!

Natural energy can be compared to the power of demons.

Is it possible to fuse the four types of energy?

The power of the demon is completely controlled by Yosuke, and can be used to suppress the violent natural energy, and then mix it with spiritual energy and physical energy.

Feeling that there was a chance, Yosuke immediately began to experiment.

Yosuke manipulated the demonic power within his body to forcibly merge with natural energy, suppressing the raging natural energy.

As expected, under the suppression of the power of the demon, the violent and uncontrollable natural energy gradually stabilized.

As the natural energy gradually stabilized, Kibuy Muzan's illusion became transparent and gradually disappeared.

Kibuyaki roared in resentment, "Ubuyashiki Yosuke, don't think I'll just disappear like this! I'm deep inside your heart! One day, I will reappear and crush your will!"

After Muzan Kibutsuji disappeared, Yosuke was finally able to conduct his experiments in peace, undisturbed by anyone.

The natural energy, spiritual energy, and physical energy that merge with the power of the demons begin to mix.

However, the difficulty involved is still very high.

Yang Jie originally thought that the four types of energy would be evenly distributed and maintain a balance.

However, after being evenly distributed, the power of the demons and the energy of nature became too skewed, directly devouring spiritual and physical energy, making it impossible to mix.

Therefore, Yang Jie increased the proportion of spiritual energy and physical energy, and finally, through continuous testing, the four types of energy reached a balance.

After successfully merging, Yosuke's body changed once again. His blood-red hair turned deathly white, his pair of bone wings split into two pairs, and dark green lines resembling tear stains extended from his face to his chin, making him look as if he were crying.

Yosuke's true form also regained consciousness.

While Yosuke was still wondering how he ended up in the sky, he looked down.

"Huh? Where's the island? Where did it go? Did it fly off somewhere else?"

Yosuke scratched his head in confusion, only to bump his forehead.

Sensing something was wrong, Yosuke flew to the sea, where his reflection was mirrored.

Yosuke was startled. What was going on with those bone wings, those demon horns, those tear stains, and that eyeshadow?

Just then, the system displayed a notification.

[Congratulations, host, you have obtained the Demonic Immortal Mode (Pseudo) and have been granted one chance to draw a prize.]

Yosuke was completely bewildered: "Demon-transformed Sage Mode? And it even has a fake version, what's going on?"

The system explained:

The new power generated by the combination of natural energy, spiritual energy, and physical energy is called Sage Chakra in this world. Sage Chakra allows one to enter Sage Mode, significantly increasing one's offensive and defensive capabilities.

[The host's current form is Sage Mode, but because demonic power has been incorporated into it, the Sage Chakra now contains demonic energy, making it Demonic Sage Mode.]

[As for why it's considered fake, it's because the host forcibly mixed the four types of energy together, so the Demonic Immortal Mode is merely an unfinished, half-finished product.]

"I see..."

Yang Jie breathed a sigh of relief. He had underestimated natural energy, thinking that he could easily tame it with his strength, but he almost failed.

Risk and reward go hand in hand; this could be considered a blessing in disguise.

Recalling Kibu Muzan in his mind, Yosuke asked somewhat seriously, "System, is Kibu Muzan really completely dead?"

[Kibu Y Muzan is dead; there is no doubt about that.]

Although Yosuke knew in his heart that Kibuy Muzan in his mind was just an illusion caused by the violent natural energy, Yosuke still wanted to get a clear answer. After receiving the answer, Yosuke felt relieved.

Yosuke sensed the location of Yekura and Jugo, and flew away with his bone wings.

Upon arriving at the island where Yosuke and Jugo were, Yosuke and Jugo instinctively took a step back when they saw Yosuke's posture.

Yekura asked cautiously, "Yosuke, have you regained your senses?"

Yosuke deactivated his demonic sage mode and asked in confusion, "Did I just lose my mind?"

Jugo swallowed hard: "Yes, Yosuke-sama, you just lost control and destroyed the island we were on."

"What?!" Yosuke's eyes widened in disbelief.

The island used to cover an area of ​​about ten square kilometers, and I actually destroyed it.

Although Yosuke is very powerful, destroying an island is almost impossible for him.

This is different from destroying a country; it's about making an island completely disappear from the map.

Moreover, even if Yosuke were to re-enter Demon Sage Mode, he felt he wouldn't be able to destroy the island.

Yosuke has no memory of losing his mind during that period, so he has no idea what he did to destroy the entire island.

This reminded Yosuke of Zenitsu, who would become several times stronger after losing consciousness.

Chapter 263 Orochimaru's Base Outpost

Although Yosuke forcibly suppressed the natural energy using the power of the demon, he managed to barely resolve the problem of the natural energy's rampage.

Since the power of the demon can suppress natural energy, Jugo's problem should be temporarily solved.

All you need to do is inject Yosuke's blood into Jugo's body, using the demonic power within the blood to slow down Jugo's absorption of natural energy.
