To be more specific, the origin of the breathing method is a fighting technique developed against "humans", but since Tsugakuni Yoriichi introduced the breathing method to the Demon Slayer Corps, based on other breathing methods derived from the Sun Breathing, their targets have become "demons".

Why explain this?

Because the recovery ability of the ghosts in the Demon Slayer World is too terrifying, when the techniques against "ghosts" are applied to creatures that have no self-healing ability, Zhang San will let them know what cruelty is! It was mentioned before that the thunder knife in Zhang San's hand is not a product of the earth-covering forging method (the blade will bend), and its shape is similar to the Tang sword style, with a long and straight blade.

With such a sword, not to mention using the Iai Slash with the help of the Iai Belt, if one is not tall enough, even pulling it out would be a luxury, let alone coordinating it with the Thunder Breathing to create a Thunderbolt Flash.

In order to make up for this shortcoming, the Demon Slayer's alt-account simply gave up the practice of Iai and instead adopted the Tang Dynasty's horizontal sword holding method.

First, turn the direction of the thunder sword so that the blade is always facing the enemy. Secondly, raise the position of the sword to the waist position, rotate the body, and thus speed up the sword drawing process to achieve the standard of thunderbolt flash.

To be honest, compared to Iai, Zhang San's way of drawing the sword requires extremely high physical fitness, especially waist strength, but he still chose this method without hesitation.

Cultural pride is certainly one of the reasons, but more importantly, in Zhang San's eyes, Iai is not what a gentleman does! (My personal opinion, if you are interested, you can go to Baidu to find out the role of Iai, please don't criticize me) Maybe this is the reservedness of men...

Without further ado, at the moment when the innate Qi reached his left foot and when Zhang San swung the knife, he was in a state of transparent world and felt that even time had slowed down.

After breaking the balance, Zhang San was given ultimate power. If reflected in the outside world, it was the world's original force - heat!

Lightning flashed, and where Zhang San's feet stepped on, apart from the scorch marks left by the heat, the floor was not even broken by such a huge force.

This is called making light of a heavy task.

Use every bit of power where it should be, this is called mastering power! Within ten steps, I am invincible. At such a speed, if you have not specially practiced the pupil technique, human dynamic vision alone is definitely not enough.

At that time, let alone swinging the sword to kill the enemy, you should be thankful if you don't hurt yourself.

Fortunately, Zhang San's transparent world has already been fully developed at this time. Even if the speed is twice as fast, it will not affect his judgment.

It was a very handsome face, pale but still defiant. Although he was shouting for help, his gestures showed his confidence! Wearing a jade ring on his waist and carrying a sachet, he must have been a famous young talent in the local area or even in the state. It seemed that what he said before was not all lies. At least the identity of "student" could stand up to scrutiny.

He became famous at a young age, and had a beautiful wife. For a while, he had endless romantic stories and endless strategies for maintaining the country. If the timing was not wrong, Zhang San really wanted to ask him, why didn't you freeze to death after ten years of studying? Zhang Zai, a great scholar in the Northern Song Dynasty, once said, "Establish a mind for heaven and earth, establish a destiny for the people, inherit the lost knowledge of the past sages, and bring peace to the world for all eternity!"

A great scholar of our time, Lu Wangxin, the former chief minister of the cabinet, once evaluated it as the Four Sentences of Hengqu, and used it to encourage himself.

He also called on students all over the world that if they could achieve one of these, they would have no regrets in their life. If they could achieve all four, he would not change even if it meant being offered the position of a Confucian sage.

What is Confucianism? What is the responsibility of Confucian scholars? After leaving his position as the Prime Minister and becoming a Confucian sage, the old man used his half-life to give the best interpretation.

But in the "student" or "scholar" in front of him, Zhang San did not see any expectations as the old man had said.

Indeed, genius is a aptitude, relying on talent and being unrestrained is a sentiment, and youthful romance is a temperament!

For Confucianism, or even for a young person, these are not problems. As long as the original intention of studying is not changed, after more experience in the future, it will naturally calm down. After all, who hasn’t been young? Even the most difficult Xuanmen monks have the saying "If a young man does not practice, he will indulge himself", let alone other sects?

But the premise of all this is that the original intention remains unchanged. Looking back at the time when I worked late into the night, whether it was for the future or for the people, desire is not useless. Knowing what can be done and what cannot be done is achieving something.

But now that you have become an accomplice, helping the tyrant to commit atrocities, and abandoning propriety, righteousness, integrity, filial piety, brotherhood, and loyalty, are you still qualified to talk about your original intention? Are you still qualified to call yourself a "Confucian scholar" or a "student"?

Zhang San would naturally not ask this kind of person, no, this kind of ghost, mainly because the other party did not have time to react.

Lightning flashed by, and his left hand turned into a tiger claw, first blocking the opponent's left hand, and with the help of the speed of thunder, the thunder knife in Zhang San's hand flashed by - the basic skills of kendo - against the wind!

The battle between the two lasted only a moment, and before everyone in the temple could even react, Zhang San had already appeared at the door.

In contrast, the "student" who had originally asked for help had his left arm missing, and a horrific wound that was terrifying appeared on his chest.

In order to cultivate martial arts, Zhang San had in-depth exchanges with Butterfly Kanae. With the support of modern medicine, he had a very good understanding of the human body structure. (Those who understand will understand) With just this one cut, from bottom to top, the femoral artery, aorta, pulmonary artery, and brachial plexus nerves were all irreversibly damaged, which was why the blood was pouring out.

If this knife had been inflicted on a human, even if the person had a strong will, they would still be able to stay awake under such pain. However, with such a horrific amount of bleeding, if there were no magic medicine to save his life, even if Hua Tuo were alive, he would have been unable to save the situation.

But unfortunately, the one who was injured now was a lackey, and this kind of injury was not even considered an injury to them.

Don't get me wrong, this is not to say how powerful their self-healing abilities are. The main point is that they have sold even their souls to the tiger demon, so do they still have the qualifications to say that this is their own body?

Logically speaking, the one who was injured now was only the puppet of the tiger demon, and it had nothing to do with him! As a qualified old coin, after the knife was finished, Zhang San didn't even give the other party a chance to explain, and swung the knife again.
