Kaida paid the bill a for home, where he met Yomi, who was just about to leave for her training.

  "Hi, Yomi. How's your training going?" Kaida asked.

  "Leave that aside. You actually trained for three days straight! What about your health? Didn't we promise each other that we wouldn't be reckless anymore?" Yomi's face was full of as she spoke.

  "Don't worry, Yomi. Sensei gave me a pill that keeps a person awake and full of energy for three days straight, with only one downside: a full day of exhaustion. Because of this, today is my holiday."

  "Who said I was worried about you, IDIOT!" Yomi retorted before st off.

  'I will never uand her,' Kaida thought as he headed toward his bed for some mueeded sleep.

  Kaida fell asleep at 5 AM, and when he woke up, the clock showed 1. He assumed it was 1 PM and that he had slept fht hours straight. But whe out of bed to stretch, he was shocked to see that it was dark outside. He hadn't slept for just eight hours—he had been asleep for a full 20 hours!

  This was surprising, as in both of his lives, he had never slept that long. Now he uood why Yukihiro Seold him to eat twice his normal serving—because he knew Kaida would be out for such a long time. It made sense now; the 20 hours of sleep was due to the pound exhaustion of three days of exercise.

  Kaida went to his fridge, unsurprised to find only nutrient bars inside. He took out a few and ate them. With nothing else to do, he meditated for two and a half hours, the his es in different dires to buy things for breakfast.

  At 4 AM, Yomi woke up, not because of her arm but because of the smell of breakfast ing from Kaida's house. She quickly pleted her m routine, and just as she was about to opee, the bell rang.

  "Yomi, I made breakfast for both of us, so do a nutrient bar right now. After you freshen up, e to my room for breakfast."

  "I'm ready now, let's go," Yomi replied, excitement apparent on her face. Kaida just nodded, and they went to his house.

  One of Kaida's es opehe door and served breakfast while another ed the kit utensils.

  "I'm really gd you learhe Shadow e Jutsu. This is the best way to use it," Yomi said.

  Kaida just ughed at this.

  After breakfast, they headed to the training area.

  Yukihiro was once again waiting for them. He handed Kaida another soldier pill, and ahree-day sparring session began. Kaida could feel the improvement in himself.

  Yukihiro was surprised that Kaida hadn't pined about his teag methods. It wasn't the first time he had taught someone, and most of his students would usually pin about only learning the basics, which they could have learned on their own.

  But Kaida was different; he did exactly what he was told without question. Occasionally, he would ask for crification, but it was mostly about their duels and how he could rectify his mistakes.

  Yukihiro was also impressed by Kaida's talent. He was now fident that Kaida could handle any non-ninja swordsman on his own. Although ninjas were a different case, Kaida had only been practig for six days. Yukihiro was starting to believe that Kaida might not only reach his level iure but might even surpass him.

  After ahree days of tinuous practice, Kaida slept for 21 hours straight. After a hearty breakfast, he made his way back to the training area with Yomi.

  This time, the training was different. Yukihiro's e taught Kaida how to parry and defend against attacks. They spent a full day on this before resuming their duels.

  But this time, it was more iing. Yukihiro started attag Kaida, so Kaida had to block his attacks as well as unch his own. For two days straight, they sparred against each other, day and night. O day, with only ten hours left before Kaida had to rest for a day, Yukihiro gave him a break.

  Kaida realized that while his growth arent, he still hadn't learned what he inally wao when he asked to learsu. He wao learn chakra flow, the teique of coating your on in chakra to make it super deadly.

  He only had 15 days with Yukihiro at the start, and now only one more round of three days of training was left before Yukihiro would leave for a mission. Kaida decided to ask if he was ready to learn chakra flow or if there was something else he o do.

  He approached Yukihiro and asked, "Sensei, I read about chakra flow in the library, and I was curious about it. It was written that chakra flow makes kenjutsu capable of peting against ninjutsu asu, but you haven't taught me anything about it yet. Am I not qualified enough to learn it?"

  "Kaida, I think you have a misuanding. It's not chakra flow that makes kenjutsu powerful; it's the user. No matter how powerful or sharp a sword is, it 't kill the oppo if the wielder isn't strong enough. As for chakra flow, it's not that difficult, but the problem is your sword. Let me give you an example."

  Yukihiro picked up Kaida's sword but paused just before eling his chakra into it, remembering the sword's price. He set the sword down and, with a *poof*, two swords emerged from the bracelet he was wearing. He picked one up and passed his chakra into it.

  Slowly, the sword started glowing red. Yukihiro swung the sword at a boulder, slig through it like a hot khrough butter. But as it exited the boulder, the sword began to melt down.

  "The reason you 't learn chakra flow is because…"
