Chapter 10

"Ahem, learning and training are very hard, are you ready for this?"

After reading the recommendation letter, Kuwajima Jigoro had a full understanding of Ji Qingfeng. The recommendation letter described what Ji Qingfeng had done in the Demon Slayer Corps headquarters in the past two months without any exaggeration.

He was very satisfied with the person recommended by the lord, and he also knew that the other party had practiced hard in the past two months. Now he said this just to show that he had agreed to accept him as a disciple.

"No problem, please train me as much as you want, Mr. Kuwashima."

Ji Qingfeng understood what Kuwashima Jigoro meant and said solemnly

""Yeah."

Kuwajima Jigoro looked at Ji Qingfeng with satisfaction, then stared at Agatsuma Zenitsu

"Let me introduce you first. This is Daoyu Xiyue, the first disciple among the three of you."

"Hello, Brother Daoyu, my name is Ji Qingfeng.

Ji Qingfeng greeted Daoyu Xiaoyue with a kind smile.

Of course he knew who Xiaoyue was. It was understandable that he was afraid of death, but it was disgusting if he had a bad character. It was a waste of air for him to be alive.

"Um"

"Teacher Kuwashima, I'm going to practice."

After saying hello, Daoyu Xiyue said something to Kuwashima Jigoro and walked towards the woods on the mountain.

Daoyu Xiyue's temperament made Kuwashima Jigoro shook his head helplessly, and he didn't explain much, but continued to introduce his disciples to Ji Qingfeng.

"This is my wife Zenitsu, my second disciple."

"Hello, Senior Brother Shanyi, my name is Ji Qingfeng"

"Eh? Hello, hello, I'm Zenitsu Agatsuma."

It was the first time that Zenitsu Agatsuma was called senior brother by someone else. He was a little embarrassed and hurriedly stood up to respond. Because Ji Qingfeng looked much older than him, he didn't call him junior brother.

Seeing his appearance, Ji Qingfeng smiled from the bottom of his heart. He still had a good impression of Zenitsu Agatsuma, who made a sword every season and was handsome every season.

"Qingfeng, do you mind me calling you that?"

"Master."

Ji Qingfeng shook his head slightly and looked at Kuwajima Jigoro seriously.

"The letter said that you have been exercising and practicing sword swinging every day for the past two months?" Kuwajima Jigoro looked up at his new disciple.

"Yes, Master, it is a little late for me to start learning swordsmanship at my age. If I want to achieve something, I must study hard and practice diligently."

Ji Qingfeng took a breath and continued,"Before, no one taught me and I only practiced swinging the sword."

"Yeah, show me."

"Yes, Master."

Ji Qingfeng stepped back a few steps, turned sideways, drew out the sword from his waist, took a deep breath and began to concentrate his attention, imagining that the green-skinned ghost was standing in front of him. Whoosh

, whoosh.

He swung the sword continuously without giving himself a chance to breathe.

Agatsuma Zenitsu on the side had his eyes wide open.

What did I see? Didn't he come here to become his disciple? How come his sword is faster than mine? Does grandpa have such high requirements for his disciples now?

After being surprised, Agatsuma Zenitsu was delighted. Since the master had accepted such a powerful disciple, he should not force me to practice too much.

""Huh~"

Ji Qingfeng felt his stamina was decreasing and his sword speed was slowing down, so he sheathed the sword. He rarely used all his strength during training, as it was too exhausting. During training, he practiced swinging and finding ways to draw the sword faster. He only had so much stamina, and the faster he used it up, the less time he had to practice.

"Master."

Ji Qingfeng took a breath and waited quietly for Sangdao Jigoro's instructions.

"Well, the knife-holding posture is very standard, and the speed of the knife is also good."

Sangdao Jigoro looked at Ji Qingfeng with burning eyes.

"The only problem is that the force used during the chopping process is too strong, which makes the process of connecting the previous chopping to the next chopping very stiff."

"I think you should use more strength to force the next cut to make up for the stiffness, right?"

"Yes, Master."

"Did you feel that your physical strength was decreasing very quickly just now, and each swing of the sword was more tiring than the last?"

Ji Qingfeng's face showed a look of realization when he heard this. When he first started practicing, he really used 70% of his strength, leaving 30% for defense and changing his moves.

But later, when he thought that he didn't need to defend, he started to swing the sword with all his strength. In addition, he rarely swung the sword so quickly and continuously, so he didn't realize his problem.

It seems that even if his body is special, he can't use all his strength for every swing, and he still needs to keep some strength for changing his moves.

"I understand, Master."

My wife Zenitsu looked at her grandfather with a confused mind, then looked at Ji Qingfeng.

What did he understand? Why didn't I understand?

Isn't swinging a sword the same as swinging it with all your strength?

""Yeah."

Kuwajima Jigoro smiled and nodded, looking at Ji Qingfeng with more satisfaction.

"You came to Taoshan to learn breathing techniques, right?"

"Yes, teacher."

"Do you know the principle of breathing method?"

Kuwajima Jigoro asked with a serious look.

"To be clear, the breathing method is to adjust the rhythm of breathing, absorb a large amount of oxygen into the body, and integrate it into the blood to enhance the cardiopulmonary function."

Ji Qingfeng knew the principle of the breathing method, but knowing the principle did not mean that he could use it.

Rhythm, what kind of rhythm?

How does oxygen integrate into the blood?

It's not that he hasn't tried it before, but in the end, he only felt tired, chest tightness, and dizziness.

Based on his experience, he came to a conclusion that he was drunk on oxygen.

He had similar symptoms after returning home from Tibet before the time travel.

So if no one taught him, he couldn't figure it out by himself. He wasn't God's biological son, Tsugikoku Yuichi.

"That's right, ghosts are stronger and faster than us, their injuries can heal quickly, and their limbs can grow back after being cut off, but we humans can't do that."

Kuwajima Jigoro tapped his cane.

"Therefore, we can only rely on breathing techniques to resist and fight against ghosts."

"A long time ago, ghosts appeared in this world. Our ancestors created a breathing method to fight ghosts. The breathing of thunder is"

Before Kuwajima Jigoro could finish his words, Agatsuma Zenitsu started wailing."

"Zenitsu!!"Kuwaijima Jigoro glared at Agatsuma Zenitsu who interrupted him.

"Ah~ Grandpa, I was wrong!!"

Agatsuma Zenitsu knew that he had done something wrong again, but he really couldn't control it. Grandpa had repeated these things too many times, and his ears were calloused from hearing them.

"It seems that the days ahead will be very lively."

Ji Qingfeng smiled with emotion as he watched their master being kind and their disciples being filial.
