Xuan Fang didn't know how strong Onimusuji Muzan was at his peak, and he didn't need to know. He only needed to know that Enichi Tsujikuni could kill Onimutsuji Muzan.

What remains is what method can be used to ensure that Kibutsuji Muzan will be killed 100% under normal circumstances.

Bear!

Fighting energy surges crazily, forming a flame-like phenomenon while clinging to the blade. Try the first method first, using the fastest speed and the strongest power to kill Wu Mei in an instant!

Bang!

The monstrous flames were instantly detonated under the feet, and the ground collapsed. The ultimate power brought about the ultimate speed.

Almost instantly, Xuan Fang appeared behind Kibutsuji Mukai from ten meters away. There was no trace of blood on the dark red sword. The veins on the back of his hand popped out and his brows were slightly furrowed.

Puff! Puff! Puff! Puff!!

boom!

As blood burst out from dozens of knife edges, Kibutsuji Mumei's flesh and blood dispersed into thousands of pieces in a terrifying shock wave, flying in all directions.

It's not that he can only split so many, but that his remaining body can only split so much. The blow just now not only destroyed all of Kibutsuji Muzan's heart and brain, but also burned half of his flesh and blood in an instant!

Back then, Jiguo Yuanyi's attack also burned part of his body in an instant, but it was the first time he saw Wu Mei. After all, he was careless, and Jiguo Yuanyi did not have as inhuman strength as Xuan Fang.

"Hiss!" After breathing for the second time, Xuan Fang turned around and used the Breath of the Sun move. Countless sword strikes in the sky filled with fire burned all flesh and blood.

A few seconds later, when all the dust settled, Xuan Fang looked at the ground that seemed to be burnt. With a knife, the last piece of flesh and blood hidden underneath completely disappeared.

[Congratulations to the host for successfully challenging! Obtaining perfect blood! 】

[Perfect Blood: It can transform the user into an immortal and perfect creature. The side effect is that it will become dependent on human flesh and blood. 】

Xuan Fang had seen this thing before, just when the shopping mall system appeared. It was one of the most valuable things in Demon Slayer World, worth 50 trial points. Another thing of the same value was the Breath of the Sun, also worth 50 trial points.

If it hadn't had that side effect, I'm afraid the value of this thing would have doubled.

"It's not enough..." Xuan Fang was not satisfied with this result. If it weren't for the system's limitations, a few seconds would have been enough for Kibutsuji to escape.

Onimusuji Muzan's strength is only for other pillars and demon slayer swordsmen. For Xuan Fang, what is really difficult to deal with is Onimutsuji Muzan's caution.

To put it bluntly, he was afraid of death. It was precisely because of this that Xuan Fang managed to escape when he first encountered Wu Misai, but now it was just the opposite.

In reality, it is absolutely impossible for Oni Wu Tsuji to escape, so Xuan Fang has two choices, either to trap him, or to kill him in an instant, neither of which is easy to do.

Especially the former.

The power of the shock wave released by Onibatsuji Mumei is terrifying. It is impossible to trap him by conventional means, even with magic...

Buzz!

The scene in front of him changed. Xuan Fang left the challenge space and suddenly asked: "Sara, what level has your magic practice reached?"

About two months have passed since Sara relied on his magic power to complete her transformation. Xuanfang knows that he has no magic talent. Although he is still accumulating magic power, the effect is not ideal and the increase in magic power is quite limited.

.

As an elf, Sarah is born with a strong affinity for natural elements. Coupled with her unique natural abilities, her magic ability can be said to be maxed out.

"You can already use advanced magic, Master." Sara's figure appeared beside her. She seemed to like long skirts, so she transformed into a black long skirt.

Xuan Fang never paid attention to it, but at this time he discovered that Sarah seemed to have grown a little taller. She had a baby-fat face before, but now her facial features looked more obvious.

"Advanced magic..." Xuan Fang was silent for a moment, then raised his hand and rubbed his eyebrows.

I have been pondering over it for so long, and even used magic crystals to barely be able to use intermediate magic, and it will be empty after using two.

If the magic power consumed by high-level magic is calculated in terms of quantity, even the lowest high-level magic is at least several times that of mid-level magic. This does not include the quality of magic power, and I am afraid it will be more than that.

"By the way, I forgot about it." At this time, Xuan Fang also remembered that he still had a few magic crystals. He took one out of the system space and put it directly into Sara's hand, saying: "This is for you, for you

Improving your magic power or using magic should help."

"...Well." Sarah was a little at a loss, but after seeing Xuan Fang's eyes, she whispered: "Thank you, Master."

"It's okay, tell me all the magic you can use."

"yes."

At that moment, Sarah talked about the magic she had learned. Xuan Fang didn't know many of them, but most of them were elemental magic. Other than that, it was her racial talent magic.

For example, like the dark elves that were summoned before, you can use the corpse to directly summon dark slaves with a certain strength, or even death knights, but whether the latter can be controlled is another matter.

Xuan Fang finally settled on two magic spells, Dark Barrier, and one of her racial talents, Dark Wen Yao.

Although the former also belongs to the elemental magic of the dark system, Sara is naturally more compatible with dark elements, so she is better at these magics and the effects are better.

As for the latter, Xuan Fang has seen it before. Sara possesses him, and the patterns on his wrists will appear on his body, allowing him to temporarily gain Sara's physique and magic power, and even master the magic. It's quite scary.

Talent, but it corresponds to a huge consumption of magic power.

"I'll give this to you. If necessary, if the magic power is not enough, just use it." Xuan Fang finally gave her the bottle of special magic potion. It was too wasteful for him to use it.

"Master, I..." Sara grabbed the corner of her clothes and hesitated, which made Xuan Fang look at her with some confusion. He seemed to have mustered up the courage, looked up at Xuan Fang and said seriously: "Thank you."

"...It doesn't matter." Xuan Fang scratched his head, thinking it was something important.

"I..." Sarah's face turned red and her face bulged, but seeing that Xuan Fang had turned around and left, she quickly followed him.

…

When Xuan Fang returned to Butterfly House, the sky had already darkened. Nezuko was standing at the door, looking around, apparently waiting for Tanjiro.

"Yeah!" Seeing Xuan Fang approaching, Nezuko ran over excitedly, dancing and gesticulating something.

After learning that Tanjiro would not be back today, Nezuko's eyes instantly filled with tears, and she looked like she was about to cry.

"Nezuko, you can't run around. Okay, come with me, uh... Master Xuanfang, I'm sorry I didn't see you." Kanzaki Aoi ran over. Nezuko couldn't run around at this time, but he saw Xuanfang again.

Fang, salute quickly.

"It's okay." He waved his hand. The Demon Slayers were very hierarchical. Even if they knew each other, they would keep a certain distance. He pointed at Nezuko and said, "Take her back. I have some things to deal with."

"Yes." Xiaokui then took Nezuko away.

After the two left, Xuan Fang turned his head and looked at the woods nearby. A black figure was already standing quietly under a tree.

Xuan Fang asked: "It's so late, what's wrong?"

"My lord is looking for you." Where the black shadow stepped out of the shadow, it was Immortal Kawa Saneya. This guy was so violent that he couldn't hide his aura even if he wanted to.

Not to mention Xuan Fang, if he hadn't moved quickly enough, even ordinary people would have been able to feel the violent aura like a wild beast.

"I got it, I'll go now." Xuan Fang nodded and went directly to Ubuyashiki Residence, followed by Saneya Immortal.

A few minutes later, the two came to Ubuyashiki Yoshiya, who was staggering from a nearby house and needed Ubuyashiki Amane's support during the process.

"Shiya, please go back first. I want to talk to Xuan Fang alone." This was the first thing Uyashiki Yōya said after sitting down.

"Yes." The only one Shiya was convinced by was Ubuya Shiki Yōya. After hearing this, he bowed and left.

Xuan Fang looked at Ubuya Shiki Yaoya calmly, somewhat confused about the other party's intention of coming to him. Could it be that Mingyu Xingming had told Ubuya Shiki Yaoya about his plan?

If Ubuyashiki asked, maybe he would tell him, otherwise with his sad personality, since he agreed to Xuanzang, he wouldn't tell Ubuyashiki Yoshiya, at least not now.

"Lord." Xuan Fang nodded. In his opinion, even if Ubuya Shiki Yaoya died, he would not be able to bring much advantage. In this case, it would be better to follow his own plan.

"Cough!" Before he could speak, Ubuya Shiki Yoya coughed first, and Xuan Fang could clearly feel the smell of blood drifting over.

"We Uyashiki clan have a talent, that is, our intuition is very keen, ahem... we rarely make mistakes." Even at this time, Uyashiki Yaoya's voice had an inexplicable affinity.
Chapter completed!
