After Ichiro finished washing up, he was about to go out when Minoru Immortal called him and took out a wooden knife from the entrance cabinet of the guest house.

This wooden knife didn't look special, but it felt extremely heavy in the hand, and Ichiro squeezed it hard, and was surprised to find that the material was harder than iron, and the force of up to twelve points actually pinched it without moving.

"What is this?"

Immortal Chuan took out a wooden knife with the word "wind" written on the hilt of the knife, and swung a pale cyan wave at the door, and then the wave spread into an invisible air flow in the sunlight.

"How can an ordinary wooden knife survive the training of the column! This is a custom-made training knife for those of us, and it is said to be stronger than the train tracks, and I don't know if it's real or not. ”

After all, the cost of training with a Japanese wheel knife is too great; An ordinary wooden knife can be broken in less than a few swings.

This particular wood is just right.

Ichiro suddenly discovered that there was a blue piece of iron on the side of the wooden knife in Immortal Chuan's hand.

"Speaking of which, you don't know if you're fit for the Wind Breath."

Immortal Chuan pointed to the cyan piece of iron and said, "In order to simulate the effect of the breathing method when practicing, a piece of Japanese wheel iron is also installed on the side edge of this wooden knife. ”

"It just so happens that no one has used this wooden knife in your hand, and this piece of iron has not changed color, so you can grasp it like this...... I'll take a look at ......"

Ichiro followed his instructions and gripped the hilt of the wooden knife, and the silvery-white metal visibly changed.

At first, it was a little yellow, like autumn leaves, but immediately a blue-black mist poured out, like a thin veil covering the yellow, and finally the iron sheet turned into a deep and bold dark gold.

It's like the kind of old gilded Buddha statue, which looks old and luxurious, and it is also quite in line with the identity of Genichiro as a Sengoku daimyo.

"Is there anything special about this color?"

Ichiro asked if he didn't understand.

He remembered that the blade of the butterfly shinobi was purple, and the Butterfly Chanae's Hinawa knife was peach.

"If it's golden, then you should be more suitable for Thunder's Breath. However, there has been a cyan ...... just now. So, you and the breath of the wind should be about the same. ”

[Thunder and wind? 】

Ichiro wasn't too surprised.

Practicing Ba Zhilei and Ba Liu's swordsmanship, which requires a short period of time in the air, originally relied on these two powers.

It was not surprising that the Nichiren knife would turn into this color.

In this way, the two set off from the guest house and went to the martial arts arena near the gate.

Along the way, the immortal Minoru explained to him the principle of the breathing method according to his own understanding.

In short, the breathing method can increase the physical functions of the swordsman, especially the strength and toughness, by increasing the body's temperature and breathing efficiency, so that they can perform all kinds of unbelievable movements and complete those extremely powerful sword shapes.

For beginners, a few minutes of breathing is the limit, while senior team members can last up to an hour. As for the column, it is necessary to turn the breathing method into an instinct that is no longer harmful to the body.

After an overdose of breathing, there will be a long recovery period.

In Stringichiro's understanding, using the breathing method is equivalent to knocking a Yaksha candy.

And this is just the first buff of the Demon Slayer Swordsman.

On the second level, there is their Nichiren knife.

Not only can the Nichiren sword attract various forces in nature like a medium, but the Japanese wheel sword of the right color can increase the power of the swordsman's slash.

For example, blue is to water; Cyan is in the wind; Yellow to the thunder......

In turn, the swordsman's breathing method can also enhance the tenacity of the Nichiwa sword.

This also explains why the Nichiren knife used by Koichiro always "does not live long".

Since a Nichiren knife has changed color, it is difficult for another person to use it, so the Nichiren knife of the Ghost Slayer Team cannot be reused.

Therefore, the Japanese wheel iron is really a piece less than a piece.

Then again.

The two walked along the way, and the passing team members saluted one after another.

Although the immortal Minoru Kawa almost changed his face, his white hair and open-chested dressing style were still retained, and the team members immediately recognized his identity.

This is the only person who has met with the ghost king in hundreds of years and returned completely, which is simply a living legend.

In order to boost morale, Mrs. Tianyin announced the news last night. The swordsmen finally have some idea of Onimai Tsuji.

Because of these reasons, the team members looked at him with admiration and respect, and with Immortal Chuan's still handsome face, their senses of the wind pillar were also a little less afraid of the past.

As for Genichiro, almost all the team members who were not scheduled last night went to see his "performance".

The headless monster that had plagued them for several days was so easily cleaned up by him.

The purple flames and the gorgeous and intricate sword skills had long been deeply engraved in my mind.

In fact, it didn't take much effort to solve the headlessness.

Although the leaderless was released by Oribe Masayuki, it was controlled by him, and Ichiro just used the Flying Divine Paper to perform a restraint relationship, and he easily cleaned it up, which can be regarded as a relief for the warriors of the past Ashina Country.

After killing the headless, Genichiro also obtained a special item, namely the Attack Royal Spirit Descent, which has the same effect as the Attack Candy, except that he does not need to eat sugar.

As a result, he has more inventory to sell to the Demon Slayer.

But the biggest gain is the huge amount of prestige.

The 200,000 reputation points that were planned to be collected before the year were completed in less than a day after coming to the Ghost Slayer Team.

Sure enough, this is the right place to gather wool.

When the two arrived at the martial arts arena, Kuano Kuang had been waiting for a long time, and there was another familiar figure beside him, which was Butterfly Ninja.

"Hey, you guy, what's ......?"

The moment Butterfly Shinobu saw the immortal Kawa Minoru, the diary of the sick leaf in his hand fell, but Ichiro still caught it with a wooden knife in time and scooped it up for her.

"Hahahaha, Xiao Shinobi, look," Kuano Kuangjin suddenly reached out and hugged the neck of the immortal Kawa Minoru, "After those scars, is it less manly?" ”

"Poof." Butterfly Shinobu was amused by Immortal Chuan's unbearable expression, "You said yes, right?" ”

Seeing that the two were scuffling again, Ichiro went to Shinobu Butterfly and handed her back the diary.

"Miss Shinobi, I think you seem to love this diary."

Ichiro asked, "Could it be that there is any important information in it?" ”

If so, then when the sick leaf comes out of the confessional bath, he will have to ask about it.

"Well, although the diary is written by a ghost, most of the recipes in it are unbearable to look at......"

Butterfly Shinobu frowned and flipped through a few sheets of paper full of ingredient lists, stopping at an illustration, "But I have to say, this guy is still a daring naturalist. ”

"Like here, you see ......"

She pointed to the illustration, which looked like small white umbrellas clustered together, "This plant is called poison ginseng, not a native Japanese plant. ”

"He wrote in his diary that the so-called poison ginseng (poison hemisine) is the kind of poison that once poisoned Socrates, and the poisoned person will start from the lower limbs and gradually feel paralyzed (yes, it is the kind of poison that made the prostitute Taro unable to move in the Battle of Flower Street, the effect is similar, and the author only found this prototype)."

Ichiro was stunned, "Who is Su Ge......"

"It doesn't matter."

Butterfly didn't bother to explain, but turned back a few pages excitedly, "Look here, Kazuha writes, he thinks that the life of ghosts is so tenacious, not because they are naturally immune to many poisons, but because they can produce antibodies to different poisons faster than other creatures. ”

"This means that although Kimai Tsuji has overcome many poisons in Japan, it is likely that he will not be immune to those foreign toxins that he has not seen."

"In order to test my guess, the diseased leaves made an extract of poison ginseng......"

At this point, her dark purple eyes even began to glow.

"The result is right with what he thought, this foreign poison will have an effect on him immediately!"

"For the first time, he only consumed an extract that could be lethal to ordinary people, and his body stiffened for up to an hour or two! It wasn't until he drank it a dozen times that he developed resistance to the poison, just as he was able to resist wisteria flower poison. ”

"But what if we mix this poison with wisteria flower poison?"

"I can't wait to see the results."

Looking at Butterfly Shinobi's smile that was getting more and more off, Genichiro felt deeply worried about the future of ghosts, especially those ordinary ghosts.

"That's a good idea." Genichiro nodded, "Then I'll call the people below to prepare the experimental site and medicine as soon as possible, and you will be able to devote yourself to research soon." ”

"Well, we'd better find some more poisonous plants native to the Americas and Africa." Butterfly Shinobu suggested, "Since the sick leaves can think of overcoming weaknesses, Onimai Tsuji can also think of it sooner or later, so the faster we go, the better." ”

"I see."

The strength of Onimai Tsuji is not natural.

In order to become the strongest creature in the world, he is constantly searching for and overcoming those that can threaten him.

There is no weakness in order to be called perfect.

The so-called survival of the fittest and survival of the fittest, the first sentence is often not necessarily true, but the latter sentence is the truth.

It's just that the fittest often mistakenly think that they are better than other species and are the winners.

It's like Oni Mai Tsuji no miserable.

"If only I knew where the other notebooks were." Butterfly Shinobi's expression was a little regretful, "Who knows how many good things are in it." ”

Ichiro left a little more heart on this sentence.

Soon, the senior brothers over there won and lost in two points, and it was still Immortal Chuan's victory.

The Devourer had healed many of his dark wounds, and Immortal felt that his manipulation of his body was obviously more comfortable than before, but he couldn't release the wind blade with his bare hands like he did yesterday anyway. It's like yesterday, but it's just a flash in the pan.

"Ahem, ahem!"

Masashi Isono expertly got up from the ground, coughed into his fist a few times as if nothing happened, and came to Genichiro and Butterfly Shinobi.

"I just let him just now, you can't underestimate me like this."

"Next, let's talk about your training mission today." Speaking of business, the smile on Kuang Jin's face narrowed a little.

"Xiao Shinobi, today I have to learn the five types of the Wind Breath to make up for the lack of killing distance of the Flower Breath and the Water Breath Sword Type."

"As for Genichiro, in addition to the basic breathing method of the Wind Breath, you have another task today......"

Masano raised the index finger of his right hand.

"It's that you have to think about what kind of wind you want to become."
