The Fruit of Surgery

For the hand ghost, the person he hated the most in his life was undoubtedly Urokodaki Sakonji. He had just become a demon and was about to rely on this power to do whatever he wanted, but he encountered Urokodaki Sakonji who was captured in the deserted Fujiki Mountain and became the test target of the Demon Slayer Corps.

This kind of jealousy imprinted in the depths of his heart made the hand ghost keep staring at the disciples of Urokodaki Sakonji to kill after he became powerful. It was originally difficult to distinguish who was the disciple of Urokodaki Sakonji, but who made Urokodaki Sakonji have the habit of giving masks to his disciples? In addition, he caught the hand ghost with that mask in the first place. If he couldn't beat the old one, he couldn't beat the young one. The hand ghost was in this mentality and kept staring at the people wearing masks to kill.

Later, after Urokodaki Sakonji learned about this from Tanjiro, he felt extremely regretful. He originally gave the mask to his disciples as a talisman, but it turned out to be a death warrant.

Over the years, every generation of disciples died at the test site of the Demon Slayer Corps, which made Urokodaki Sakonji doubt his ability and think that he was not a good trainer, otherwise why did every generation of disciples die there.

Under such psychological effects, Urokodaki Sakonji became more and more demanding on his disciples. The biggest possibility that his own disciples could not pass the test was that they were too weak.

Therefore, the last stone-cutting test of Urokodaki Sakonji became bigger and bigger every year. When Tanjiro appeared, it was directly changed to the biggest one, which was a circle bigger than the stone cut by the rabbit that year.

And the training time was changed from one year to two years.

Even Ubuyashiki Yoya did not find that there was a powerful demon in Fujiki Mountain that was far beyond the ability of ordinary test members to deal with.

The hand demon was extremely smart. Every time he took action, he would kill everyone who had seen him, and he would not kill all the testers, always leaving some alive to pass the test.

"Boy, who is the person who gave you the mask?" The hand ghost stopped about three meters in front of Shen Fei.

"Urokodaki Sakonji." Shen Fei said calmly.

"It's him, are you his disciple? I didn't expect to meet him again this year, hahaha." The hand ghost laughed.

At the same time, the ground under Shen Fei's feet suddenly began to bulge, and the next moment a huge green fist rushed out from the ground and attacked Shen Fei.

The hand ghost is actually a ghost who can use blood ghost arts, but his blood ghost arts are just a lot of hands. The sudden attack on Shen Fei is to cripple Shen Fei and torture him slowly to get rid of the bad breath of being imprisoned by Urokodaki Sakonji.

Whoosh.

A cold light flashed, and the sun wheel sword on Shen Fei's waist was unsheathed, instantly cutting off the hand. At this moment, the other arms of the hand ghost attacked directly from the front, and more than a dozen arms attacked together, just like a rubber machine gun.

If Tanjiro and the others were facing this attack, they could only dodge it, but for Shen Fei, these arms were nothing. With the swing of his right hand, all the arms of the hand ghost were cut off at the first time.

"This is impossible." Although all the arms grew out quickly, the situation in front of him still made the hand ghost take a step back involuntarily.

In all these years in Fujixi Mountain, the hand ghost has never met anyone who can cut off all his arms. Even the most powerful Santo, only cut off his arms four times.

The hand ghost is very clear about how hard his arms are. Most of the people who came to test it, the sun wheel sword cut on his arms, and they couldn't even break the defense.

Speaking of this, the hand ghost waved the arms that had grown again and attacked Shen Fei again, but the next moment, all his arms were broken and flying in the sky.

After several times in a row, the hand ghost looked at Shen Fei who was walking slowly, and his body couldn't help but tremble. With Shen Fei's footsteps, he kept retreating.

"You have killed many people wearing this mask over the years, why are you scared this time?"

"You."

Faced with Shen Fei's ridicule, although the hand ghost was extremely angry, he did not dare to say the next words because of the difference in strength.

"Room, slaughterhouse." Seeing that the hand ghost did not dare to do it again, Shen Fei immediately activated the operation fruit and cut it into several pieces.

"Is this guy quite smart?" After catching the hand ghost, Shen Fei came to the cave where the hand ghost was hiding. This was a very empty cave, which should have been dug out by the hand ghost with his own power.

Compared with other ghosts in Tengxi Mountain, the hand ghost is much larger. There is nothing at night, but it is easy to be exposed to sunlight during the day.

At the same time, because of the existence of the hand ghost, other ghosts hide far away. For Shen Fei, it is a good quiet place.

"DNA, ATP, is very different from humans. By the way, why is Nezuko different?" Even ghosts need to replenish energy. Why do ghosts eat people for this? But Nezuko does not need to eat people, will?

"Forget it. If we dig deeper, there will be more and more questions." After analyzing the hand ghost's genes, Shen Fei threw the hand ghost into the refining array of the Philosopher's Stone.

In fact, there are many projects that can be studied about ghosts, such as why sunlight can have a great killing power on ghosts, why the sun wheel sword cuts off the neck of ghosts, why it can kill most ghosts, why the poison of wisteria flowers is so effective against poisons, etc.

However, since it would take too much time to study all of them, Shen Fei had to give up most of them. After all, he was not a dedicated scientist like Tony. For Shen Fei, the most important thing was personal cultivation.

The regeneration ability of ghosts was not a big secret for Shen Fei. It was related to the number of people they ate. In fact, these ghosts were very similar to the artificial people in the world of Fullmetal Alchemist, and they mainly relied on soul energy.

In fact, for Shen Fei now, it was very simple to make weapons with wisteria flower poison, and he could even make standard weapons in this regard. If he had such weapons, the speed of the Demon Slayer Corps killing ghosts would definitely be much faster.

Shinobu Kocho and others could not make it, not because they did not want to make it, but because of the limitations of the times. This era was almost the early stage of industrial civilization, which was a world apart from the technology of the Marvel world.

If there was no Philosopher's Stone Alchemy Array, Shen Fei might have done this, but now who let him have the Philosopher's Stone Alchemy Array.

"It's a pity that the sword skills of the breathing method are just special effects. In this era, they are just simple sword skills." The various sword skills of the breathing method seen in the memory are all special effects, but in reality, there are only swords, and there will be no attributes such as water, fire, and thunder.

"In this way, Urokodaki Sakonji should be able to untie his knot, and there should be no similar problems in Fujixi Mountain in the future. However, it will not take a few years. After Muzan died, this place should be abandoned." Before leaving the cave, Shen Fei blocked the entrance of the cave with a large amount of wisteria flowers, facing the ghosts running in.

Then let his little sparrow send the written letter back.

There are two letters in total, one is to Kocho Shinobu of the Demon Slayer Corps, asking her to pass it on to the head of the Ubuyashiki Yoya, and the other is to Urokodaki Sakonji, asking the Demon Slayer Corps to send it over.

In the house of the Ubuyashiki family, Ubuyashiki Yoya's face looks much better at this time, but the curse on his face has increased a lot compared to before.

After reading the letter handed over by Kocho, Ubuyashiki Yoya sighed deeply, "I didn't expect such a thing to happen in Fujishi Mountain. This is my mistake. It's a pity for those good kids all these years." His voice was full of self-blame.

"You can take a look too." Seeing Kocho's puzzled expression, Ubuyashiki Yoya immediately handed the letter to Kocho.

"Fujishi Mountain, how could it be there?" Kocho's face changed immediately after reading the content in his heart.

"I underestimated the ghost too much. Fortunately, he found it this time, otherwise I don't know how many people would be sacrificed." Shen Fei gave a very good reason in the letter, that is, he caught a person who had just become a ghost and was going to put it in Fujishi Mountain, and then he accidentally found the hand ghost.

Those things were asked from the mouth of the hand ghost, and the reason here is impeccable.

"The test at Fujishi Mountain seems to be changed later." If the hand ghost appears, there may be a retreating ghost. Before, whether it was the leader or the pillar of the Demon Slayer Corps, they didn't care about the problem there because they didn't expect that the captive ghost could survive until now.

Generally speaking, few ghosts in Fujishi Mountain live beyond five years, but here there is one who lives for nearly fifty years.

As for how to change it, it is very simple. Before the test, the pillars can just check it roughly.

"Sakuto, Makoto, and Yihang, it turns out that I harmed you." After receiving the letter and seeing the cause and effect in it, Urokodaki Sakonji's tears kept flowing down.

Thirteen disciples, all died young because of a ghost he caught casually that year. Urokodaki Sakonji certainly blamed himself.

But at the same time, because the doubts in his heart were finally solved, Urokodaki Sakonji relaxed his mind.

"Speaking of which, since Giyuu and Sakuto are in the same class, Sakuto seems to have died because of saving him. Didn't Giyuu see the hand ghost that year?"

Shen Fei was still fighting ghosts as always. Soon, because of the number of ghosts he fought, he became quite famous in the Demon Slayer Corps, which caused a lot of discussion, so that everyone in the Nine Pillars had heard of his deeds.

That is to say, now the nine pillars are complete. If there is a missing one, maybe he can become the next pillar.

Normally, a member of the Demon Slayer Corps cannot always be on the road to defeat demons. This is because of injuries. Demons have too much advantage over humans. In this case, the members of the Demon Slayer Corps want to kill demons without getting injured. Except for the nine pillars, ordinary members of the Demon Slayer Corps cannot do it.

If you are injured, you have to heal your wounds. People don’t have the recovery speed of demons. This takes time. In this case, a member of the Demon Slayer Corps who defeats a demon in two or three months is very powerful.

In this case, Shen Fei’s actions will certainly attract attention. Most of the Demon Slayer Corps admire Shen Fei, a demon-killing madman.

Of course, some people are very unhappy and think that Shen Fei has stolen their limelight. This person is the senior brother of Agatsuma Zenitsu. He is one of the few who joined the Demon Slayer Corps. He is not unhappy to kill demons for justice, but for power.

Finally, after encountering a powerful demon, he voluntarily became a demon, which caused his teacher to commit suicide.

Although there are many cowards in the Demon Slayer Corps over the years, this is the second person to become a demon. The first one is of course Yoriichi Tsugakuni's brother.

"Is the Nichirin Sword finished? It's time to go back to the Butterfly House and take a rest." After looking at the news brought by Sparrow, Shen Fei decided to go back to the Butterfly House to rest for a while after thinking about it.

"This is the exclusive Sun Wheel Sword." The exclusive Sun Wheel Sword is made with a more advanced forging method than the standard Sun Wheel Sword, and is stronger and sharper than the general Sun Wheel Sword.

Among all the Sun Wheel Swords, the Sun Wheel Sword of the Love Pillar is the most peculiar. No matter what the shape of the others is, they are all in the shape of swords, while the Sun Wheel Sword of the Love Pillar is like a whip.

Shen Fei asked himself that he could not forge the metal to such an extent even if he had alchemy.

For Shen Fei, as long as there is ore for making Sun Wheel Sword, he can directly make it with alchemy, but it is still different from the one forged by a professional foundry.

This is probably the difference between handmade products and standard items.

Just like the same clothes, with similar styles, why do you sell them so expensively, while mine are just street stall prices.

"Forget about the Nichirin Sword. It's not used in today's society. Besides, there are no ghosts that need to be killed with it. The uniforms of the Demon Slayer Corps are pretty good."

The uniforms of the Demon Slayer Corps are made of special fibers, which are breathable, thin, not easy to get wet, not easy to burn, and have certain defensive capabilities.

Although this defensive power is better than nothing for ghosts, it is definitely a big selling point if it is brought to modern society.

Huh, after taking a deep breath, Shen Fei blew hard on the big gourd in front of him. The next moment, he heard a bang, and the big gourd exploded directly.

This scene made the three little ones on the side clap their hands excitedly. As the logistics personnel of the Demon Slayer Corps, the three little ones also practiced breathing methods, which are flower breathing, which is extended from water breathing. Although they are too young and have not made much progress, it is enough for the three little ones to complete their current work.

Because the three little ones are very cute, Shen Fei took good care of them during his time in the Butterfly House, and even made some cakes and candies for them.

"Flame, water, thunder, fire, wind, five basic breathing methods." During the time in the Butterfly House, Shen Fei studied breathing methods except for occasionally playing the role of a guest doctor.

The Demon Slayer Corps is not very secretive about breathing methods. Basically, as long as you apply, you can see the relevant content of breathing methods. Of course, there are only basic contents, no extended content.

For example, the two breathing methods of fire and water, at the Demon Slayer Corps headquarters, only the basic type is available, and there are no later derivative types. For example, the derivative type of water breathing is mainly in the line of Sakonji Urokodaki.

If others want to learn water breathing, they can only expand from the basic type.

The Flame Pillar family is the breathing of fire, which is the breathing passed down from generation to generation in their family. Its extended power is very powerful.

"Thunder breathing, this is good. Maybe we can find a way to get the sun breathing from Tanjiro. With his personality, he shouldn't care too much about this."
