Starting in The Boys to Become the Ultimate Lifeform.

159. Chapter 159: Infinity Castle, Muzan, Enraged by Humiliation

The next second, a black Swamp appeared under their feet. Murata was startled, and his legs were firmly grabbed by demon hands extending from the Swamp.

"You... how could this be?" Murata widened his eyes, looking at the Swamp Demon in front of him, then at the demon hand by his leg, his eyes filled with confusion.

"Die." The Swamp Demon grinned maliciously and swung out both hands.

Instantly, Murata felt a strong pulling sensation erupt at his ankles. His legs suddenly exerted strength, wanting to break free from the restraint of the demon hand.

But because he was standing on the Swamp, he was completely unable to exert strength and could only watch helplessly as he continuously sank.

Calm down! The more dangerous the moment, the calmer he needed to be. The opponent's ability was very special, and Lord Xia Shang was also grabbed by demon claws; it seemed he had no time to attend to him.

Murata fiercely pulled away the white cloth wrapped around his Nichirin Blade and swung his blade straight downwards.

Squish!

The blade directly sank into the Swamp Demon's forearm but did not cut it off. His strength was still not enough; after all, a demon's body strength far surpassed that of an ordinary human.

"Ah!" Murata gritted his teeth and pulled the blade out. At this moment, his lower legs were already completely swallowed by the Swamp.

"Caw, caw!! Danger, danger."

Hutaro saw that the situation was wrong. A hint of human-like tension was revealed in its black eyeball. It anxiously flapped its wings, repeatedly warning Murata to be careful not to be completely swallowed by the Swamp.

Bang! The movement from beside him instantly attracted Murata's attention.

When he turned his head to look, he happened to see Xia Shang tearing off the demon's arm, stepping with steady strides, and stepping out of the area covered by the Swamp.

"I'll count to ten. If you can't deal with it, I'll take over."

Xia Shang slightly furrowed his brow. In his eyes, the struggle between Mukago and the Swamp Demon was no different from playing house.

One move from you, one move from me, it felt like a turn-based game.

Seeing Xia Shang urging her, Mukago had no choice but to unleash a powerful technique. She saw a thumb-sized scarlet seed emerge from her palm. "Blood Demon Art - Parasitic Plant."

With a whoosh! The seed in her hand was thrown out by her at an extremely fast speed, like a high-speed bullet, accurately hitting the Swamp Demon's forehead.

"What the hell is this?"

A hint of astonishment flashed in the Swamp Demon's eyes. Before it could dig out the seed embedded in its forehead, the seed itself exploded violently. In an instant, countless root hairs like blood vessels instantly expanded. The tip of each root hair was like a sharp steel needle, fiercely piercing into its body, and with the expansion and contraction of the blood vessels, turned the blood inside the Swamp Demon into nutrients.

"Get off me!"

Seeing the blood being continuously drained, the extremely angry Swamp Demon extended its arm covered in bulging veins, frantically tearing at the plant vines wrapped around its body. But with little effect; the vines it tore off grew even more root hairs in less than a second. Finally, amidst unwilling roars, the Swamp Demon turned into a spherical object wrapped in vines.

But this was not the end.

Silently, a hint of green appeared at the top of the spherical object. After the green sprout received the nutrients transported by the roots, it grew rapidly at a speed visible to the naked eye. Soon, it grew to several meters tall, and its emerald green branches were hung full of scarlet fruits.

Subsequently, under Mukago's control, the fruits immediately turned into countless cannonballs and blasted towards the black Swamp!

At the same time, she also took the opportunity to manipulate a vine and pulled Murata out of the Swamp.

"Th- thanks." Murata wiped the cold sweat from his forehead. To be honest, this was the first time in his life he had been saved by a demon. Boom! Boom!!

The moment the fruits touched the Swamp, they immediately exploded. Their power was not small.

"Damn it! That master won't spare you!"

After the Swamp Demon showed its head, it immediately shrank back in. Luckily, it had hidden its main body within the Swamp. Otherwise, it really might have been killed by that Lower Rank Four.

In Xia Shang's eyes, there were several ways a demon could die: one, being burned to death by the sun; two, being decapitated by a Nichirin Blade; three, being poisoned to death by poison made from Wisteria Flowers; four, Muzan controlling a curse to kill it directly. And the fifth type, which was also a move Xia Shang and Mukago had used, was to deplete the regeneration within the demon's body.

Once a demon's regeneration is completely consumed, it will completely collapse because it cannot regenerate.

"Caw, it wants to escape, quickly stop it." Hutaro, flying in the sky, could easily lock onto the direction the Swamp was moving.

Just at this moment.

Xia Shang drew the blade from his waist and gripped the hilt in a reverse grip. Whoosh... the surrounding air was inhaled into Xia Shang's lungs, then he used his Breathing Style to the extreme. When hot steam overflowed from the corner of his mouth, the next second, he threw out the Nichirin Blade wrapped in giant waves and blazing flames!

He saw two streams of different colored airflow rolling and roaring on the blade, emitting a startling sound similar to a sonic boom!

This is... For some reason, when Mukago saw the blazing flames wrapped around the blade, her body couldn't help but tremble, as if every cell in her body felt a deep fear towards that blaze. This fear even reached Muzan.

...

Inside the Infinity Castle, countless buildings were stacked upon each other, as if countless old Tokyo prefectures were crammed into the same space.

Here, it was brightly lit. In front of every House, hung two wooden Japanese lanterns.

The orange-yellow light emanating from them added a touch of warmth to this extremely silent space.

"Strumming!" The sudden sound of a biwa broke the tranquility of this place. In an instant, countless buildings were like a scrambled Rubik's Cube, constantly changing.

The buildings here were connected roof to roof, making it impossible to distinguish up, down, left, right, or one's location.

Even the most cunning hunter, once they entered, could not find the way out.

"Stop!" In the center of the Infinity Castle, a man with sickly pale skin suddenly opened his scarlet eyes. He wore a black patterned Haori embroidered with flowers, a cascade of black hair draped neatly over his shoulders.

And beside him was Nakime, kneeling on a bamboo mat. Nakime's skin on the back of her hands was grayish-white, and she slightly lowered her head, covering her eyes with her bangs. She was Muzan Kibutsuji's attendant, usually playing the biwa for Muzan with a plectrum. Because her face couldn't be seen, it was impossible to know if she was an Upper Rank or which Lower Rank.

Upon hearing Muzan's angry roar, Nakime stopped her playing.

"This familiar feeling is coming from a certain Lower Rank. In this world today, how could there still exist something that can make my blood feel fear." The fear buried deep within Muzan's cells awakened his memory of that man.

Under the moonlight, that sword, that unparalleled sword.

Whoosh! Muzan instantly woke up from his memory. His breathing unconsciously deepened.

"Go summon Mukago, Lower Rank Four. I want to know who he is! Why does he possess that thing!"

The humiliated and enraged Muzan Kibutsuji forcibly suppressed the anger in his heart, waved his hand and pulled Nakime in front of him, looking at Nakime with plum-red pupils. His voice was incredibly cold.
