Uchiha's Blade

Immortal Genya, 15 years old, does not know any breathing techniques, but passed the final selection of the Demon Slayer Corps.

According to his trembling confession when pressed by Mana, he relied on his ability to eat ghosts to pass the selection.

"Eat... ghost?"

Zhenna asked hesitantly: "Is this what I understand?"

Even Mana finds it hard to believe that someone can actually eat ghosts.

When you take the food, it looks very unpalatable, okay?

Immortal Kawakawa Genya said: "I can eat the flesh and blood of ghosts and obtain a short-term 'ghost transformation'. I can gain the same powerful physique as a ghost, and I may even be able to use the vampire ghost technique to release ghosts."

Although it sounded unbelievable, Mana somewhat believed it after thinking about the reactions of the previous rescue team members.

"Does your ability have any side effects? For example, if you eat too much, you will completely turn into a ghost and never come back? Also, are you afraid of the Nichirin Sword when you become a ghost? Can you bask in the sun? Have you tried it? How long can it be maintained for the longest time? Does your physical strength affect the amount of ghost power you can use? And more..."

Immortal Kawagenya's physique made Mana's research desire explode instantly. She looked at Immortal Kawagenya with gleaming eyes: "You are really a treasure!"

Immortal Kawa Xuanya: "..."

I feel like I'm afraid I won't be able to walk out of this laboratory alive QAQ

The next second, Zhenna handed something in front of him: "Here, it's part of the winding string. Let's take a bite and try it?"

Immortal Kawa Genya: "Do you really want to eat? Now?"

Zhenna said: "We agreed that you would do research for me and I would teach you the communication skills with Mr. Fusukawa."

Thinking of being able to be as close to his brother as before in the future, Genya Fusugawa gritted his teeth, took a small fragment from Mana's hand and ate it.

Then, Mana saw the appearance of Genya Fusugawa changed.

He grew ghost-like fangs, and the whites of his eyes turned black, making him look like a ghost.

Mana pulled out his Nichirin sword: "Do you mind if I chop you?"

Immortal Kawakawa Genya: "Of course I mind! - Ouch! You did it!"

Throwing the Nichirin sword aside, Mana took out the Ninja sword again: "Do you mind if I slash you again?"

"Does it help if I say you mind - ow!"

After the second slash, there was a long wound on each of Immortal Kawagenya's arms.

The difference is that the side injured by the ninja sword is recovering quickly, just like a ghost. If it is only injured by an ordinary weapon, it will recover quickly.

It wasn't until the wound opened by the Ninja Sword had fully recovered that the area injured by the Nichirin Sword began to heal.

Mana's tone was a little disgusting: "You are so weak. What I gave you was one of the upper strings. When Mr. Tomioka and I met him before, he could recover quickly even from wounds caused by the Nichirin Sword. Oh, it’s the same as being beaten or not, you just have to be so slow.”

Genya Immortal: "Hey, you slashed me twice! Are you going to tell me this after you slashed me?"

Mana blinked: "What do you want to say?"

Immortal Kawagenya: "...No, it's nothing."

I finally know how you got the name of the Great Demon King.

She is a girl who looks so cute, but is actually an out-and-out devil!

"Okay, let's draw some blood next. I'm a little curious about your condition."

From a human to a ghost, he can change back to a human again.

Mana felt that if Immortal Kawagenya's magical ability could be applied, it might be possible to turn ghosts back into humans in the future.

Next, Genya Fusugawa fully realized that the Demon King of the Demon Slayer Squad was not just as simple as slashing him twice and drawing some blood from him.

Every second in the research room is as long as an hour.

If he hadn't been worried about not being able to put it back together like a ghost after cutting it into pieces, Genya Fusugawa would have no doubt that Mana would have sliced ​​him up and studied it.

When Mana finally announced that it was over for the time being, Genya Fusugawa lay down as if he was exhausted. He felt that he would rather face one of the real top strings than be studied by Mana again.

However, Mana squatted beside him and asked curiously: "Xuanmi, how long will it take for you to transform back into a human?"

Immortal Kawagenya said: "The flesh and blood I ate is not much, I should be able to recover soon."

Mana held her watch and waited beside him. After Genya Immortal Kawakawa transformed back, Mana took another tube of blood.

Fortunately, this time she didn't just draw her sword and kill someone.

He even gently lifted Xuanya Immortal Kawa and sat on the chair next to him: "Xuanya, do you feel better? Will becoming a ghost consume a lot of physical energy? It's all because of my lack of consideration. You just passed the selection. , I’ll just let you do the experiment with me, you must be feeling very tired.”

The girl's round, almond-shaped eyes were full of worry, which was so heart-warming.

Immortal Kawakawa Genya, who was not good at getting along with girls, was on pins and needles: "Well... don't be like this, I didn't work very hard. If you don't fight or get injured, the ghost transformation will not consume too much energy."

Mana asked cautiously: "Is it really okay?"

"Of course!" Genya Fusugawa almost assured him by patting his chest: "I'm fine. I feel very good now. There's no problem at all!"

Hearing what Immortal Kawagenya said, Mana smiled: "That's great!"

Immortal Kawakawa Genya breathed a sigh of relief and was about to nod when he saw Mana turn his face and take out a tray with several pieces of ghost flesh and blood neatly placed on it: "Eat all of these from different ghosts." Give it a try? I wonder if different ghosts will have different effects on your body? You said before that you might use the bleeding ghost technique, right? Use it and let me see, and this... one of the upper strings I'm not too afraid of ordinary wisteria flowers, so I didn't try it for you, but ordinary ghosts should be effective. By the way, Miss Shinobu's poison is also here. I diluted it, and it shouldn't be fatal. Try it and let me know. I feel……"

Immortal Kawa Xuanya: "..."

Brother, I may have to give up my brotherhood with you.

The Demon Slayer Squad is really scary!

Then at night, Mana heard that someone else had passed the selection in the examination room, and then she remembered that it was getting late. Although she felt as if she had forgotten something, but...whatever, it is definitely not an important thing if she can forget it. .

Looking at Immortal Genya lying on the table with blank eyes, Mana clicked his tongue: "It's a bit weak, this one."

You just cooperated with so little work and you can’t hold on anymore?

Back then, Hashirama-sensei could hold on for a whole day and even go to the casino in the middle of the night and lose 1000 million ryo.

So she carried Immortal Kawagenya with one hand and walked out: "Xiaokui? Xiaoqing? Is anyone here? Come get some food, there is someone here who is about to starve to death!"

Fusukawa Genya was lucky enough to lie on the hospital bed in Butterfly House on the first day he officially joined the Demon Slayer Corps.

Mana was very sorry.

If I had Byakugan today, I would be able to better observe the physical condition of Genya Immortal Kawakawa.

Unfortunately, the Sharingan has excellent insight, but it does not have the clairvoyance ability of the Byakugan, let alone the flow of power and changes in the meridians in the human body.

If blood inheritance is not enough, science will make up for it.

Mana thought for a while, pulled out a piece of paper and started writing a list of instruments.

The Demon Slayer Squad must add new equipment. She had wanted to tell Ubuyashiki Yōya about this before, but unfortunately the equipment was too expensive, and there were many that could not be purchased in this world. She had to buy the materials and make them herself.

Mana mentally calculated the current research progress and crossed out some equipment that was not urgent to use or could be replaced by other methods, leaving only the most necessary parts.

"...Ah, at this price, I hope Teacher Yaoya won't scold me for spending money indiscriminately after seeing it."

But there’s no other way. That’s what scientific research is all about. How much money you invest will lead to results.

Even with a small investment, results can be achieved, but Mana feels that it can no longer be called results and should be called a miracle.

Most of the time, the power of scientific research is linked to funding.

The previous butterfly ninja was too miserable. He managed to survive for so many years relying on the Demon Slayer Corps' pile of equipment that Mana considered extremely crude, and even became a bug pillar.

...In fact, the butterfly ninja is the greatest genius of the Demon Slayer Corps, right?

The next morning, Genya Fusukawa had a nightmare all night. When he suddenly sat up and woke up, he saw Mana standing beside his bed, holding a notebook in his hand. When he woke up, he He smiled: "Are you awake? We are today - ugh! What's wrong with you, Xuanmi!"

After Xuanya Fusukawa saw her, he rolled his eyes and simply fell down.

——It must be that I haven’t woken up from the nightmare yet!

Mana: "...Well, I just want to say that I am going to the master today and our experiments will be suspended for a while."

The final selection is coming to an end. Most candidates have either passed the selection or have given up. Only a few are still persisting in playing the survival game.

Mana heard that some candidates have formed their own teams and plan to spend the last two days together.

In fact, this is not a bad idea.

There are only the last two days left. If you want to kill the ghost, this is your last chance.

Some candidates will choose to attack ghosts during the day.

As long as you collect good intelligence and survey the terrain in the past few days, you can launch an attack during the day when the ghosts are hiding because they are afraid of the sun.

Due to the limitations of sunlight, ghosts can only fight within a limited range. Even if they have a speed that far exceeds that of humans, they cannot have much effect. In addition, if you encounter a type that you cannot win, you just need to run to the sun quickly. , the ghost will not dare to chase you, which is undoubtedly a guarantee for your own safety.

Therefore, after a few days of running in, the children who participated in the assessment formed their own teams and formed a group to kill ghosts together. As long as they killed enough, everyone could average the number of kills enough to pass the exam.

Mana noticed that some Demon Slayer members did not agree with this approach, but Mana didn't think so.

Of course it would be best to have the power to kill ghosts by yourself, but if you can't do it alone, it's not a bad thing to learn to cooperate with others.

As long as you can kill ghosts, who cares if it's one person or a group of people?

However, Mana has no intention of saying this herself. The real person in charge of this selection is Tomioka Yoshiyuki. He should be the one to say these words. In addition, some of the problems exposed in this selection should also be made by him. Tomioka Giyu proposed.

Mana's point of view is as usual, the so-called "pillars" cannot be existences that can only fight and not use their brains. They are "pillars" and must bear more responsibilities.

Therefore, when Mana went to see Uyashiki Yōya, she did not take the initiative to mention the matter of selection. She only gave a purchase order that made Uyashiki Yōya almost unable to maintain a gentle expression.

"In addition, the Hidden Force complained to me last time that they were short of manpower. From my recent correspondence with everyone, it seems that the pillars have already mastered chakra to a certain level. I think it is time to come It's a special group training, and it can also help Yin solve part of the work. It's basically a good thing that kills two birds with one stone."

Ubuyashiki Yōya nodded: "Since you think it's time, let's all do special training together."

Although the chakra levels of the pillars are not high, even if they can only learn one substitute technique, their survival rate can be greatly improved.

The Ghost of Winding is far more powerful than they thought before.

"By the way, Mr. Yoya," Mana said: "As for what I said last time about tutoring cultural classes for pillars, let's take this opportunity to do it together. Special training all day long is boring. Join the cultural class. The class can just enrich their spiritual entertainment."

Ubuyashiki Yoshiya said: "I will tell them this."

"Uh-huh!"

Mana smiled and said: "After all, after the school is established, the cultural level of the team members will definitely be improved. If the level of Zhu is too low, it is not suitable. I will prepare the test papers."

Ubuyashiki Yōya looked at her happy expression, and could almost imagine Hashira's confused expression as he looked at the test paper. However, he just said unhurriedly: "Mana, don't bully her too much. , it is a pillar after all.”

After all, it's a pillar, and it's ugly to fail classes continuously.

Mana made no response.

How can you be afraid of failing the exam if you are a pillar?

After thinking about it, she turned to another matter: "As for the sacrifice for the reincarnation of the dirty land, one should be mature in the next few days, but the current technology is not mature yet, and the sacrifice itself is very weak. Before Several of them have died. Although the ones cultivated this time may be usable,... because the strength is too low, even if Tsukuni Enichi is reincarnated from the dirt, he may not be able to exert his pre-birth strength."

Yoya Shiki comforted her: "Mana, don't be anxious, your progress is already very fast."

Mana said: "Actually, this time, thanks to the blood of Black Death Mou, I found that he and Enichi Tsukuni are particularly compatible, so I used this as inspiration to specially customize a special sacrifice for Enichi Tsukuni, even though it is very weak. , it will definitely fail if used to reincarnate others in the dirty soil, but if it is Jiguo Yuanyi, the possibility of success will be very high."

Ubuyashiki Yoshiya said: "Are you going to ask him about Hinazuki's breathing?"

Zhenna nodded: "The breath of the sun is very strong, there is no need to doubt this, but obviously, the requirements for practitioners are also very high, but Muichiro is not a rare genius, you can let Muichiro try it, and I also want to ask Ask him about Hei Shimo and Wu Mei. Hei Shimo must know Jiguo Yuanyi, otherwise he would not forge the information related to Jiguo Yuanyi, but Wu Mei... I always feel that this matter has something to do with him. It must have something to do with it.”

"I understand," Ubuyashiki Yoshiya said, "Mana, I'll leave the rest to you."

If a user of Breath of the Sun can really appear in the Demon Slayer Corps again, this will undoubtedly greatly enhance the strength of the Demon Slayer Corps.

Mana was full of confidence: "No problem! But regarding Black Death Mou... Teacher Yaoya, cultivating sacrifices consumes materials very quickly. Two swords are not enough. With this experience, I will definitely be able to cultivate it next time." A better sacrifice is coming, so... I think it is necessary to steal another knife and bring it back."

Yasuoya Shiki: "..."

Please let Hei Shimo go.

I'm almost ashamed of being stolen by you.
