After having lunch, Haruki went out and found a blacksmith's shop.
Although this wasn't the Land of Craftsmen, due to the large number of samurais, the demand for relevant products naturally emerged.
After explaining his requirements to the boss, Haruki got a complete set of weight - bearing equipment.
Back at the inn, he called Kakashi over.
"Try these."
Haruki pointed at the weight - bearing equipment on the ground.
Seeing this familiar equipment, Kakashi couldn't help but think of his lifelong rival, Kai.
He often used such weight - bearing equipment.
After strapping the weights on his hands and feet, Kakashi felt like a robot, and every move was a struggle.
Haruki smiled and said, "If you want to become a master of kendo, you can relax the requirements for chakra, but you can't neglect your physical fitness."
"I understand."
Kakashi took a deep breath. He had to get used to the suddenly increased burden first.
Haruki checked the time, led Kakashi out of the inn, and expanded his sensory ability.
The Land of Iron was full of mountains and snow, so it was easy to find a quiet place.
He expanded his sensory ability, activated the Flying Thunder God Technique, and when he opened his eyes again, they were in front of a mountain peak.
"Okay, let's run around the peak ten times first."
Haruki estimated that one lap was about five or six hundred meters.
Since Kakashi had just put on the weights, he definitely couldn't overexert himself to avoid getting injured.
Hearing these familiar words, Kakashi thought of Kai again.
Should he shout something about the passionate youth at this moment?
Kakashi couldn't help but shake his head, trying to drive this terrible thought out of his mind.
No matter how embarrassing it would be, he would never imitate Kai.
Although such a man was really terrifying.
Kakashi glanced at Haruki without saying a word and started running.
Haruki stared at his back and regretted not bringing Kai along.
If Kai were here, Kakashi would probably be more motivated.
Time passed.
Kakashi increasingly felt that his limbs were like they were carrying heavy mountain peaks.
The more exhausted a person was, the more sensitive they became.
This was exactly his current state.
What he originally thought was a bearable burden had now become an unbearable weight.
However, his character was quite tenacious and positive.
Moreover, he didn't lose his teammates, dad, or teacher like in the original story.
After ten laps, he barely managed to steady himself. In front of Haruki, he gasped for air like a fish out of water.
Haruki threw him a scroll.
"This scroll records the details of Niten Ichi - ryu. These days, you should first work on your physical fitness, then memorize Niten Ichi - ryu. Once your body gets used to it, start your practice."
"O...Okay, Teacher."
"Yeah, of course, you can't abandon your family - inherited swordsmanship. When you're facing an enemy, only draw your second sword when you can't defeat them with the first one."
Thinking of such a scenario, Haruki couldn't help but smile.
Some people will definitely be deceived.
They thought your strongest swordsmanship was one thing, but they didn't expect you to have an even stronger one.
Kakashi felt Haruki's scheming again.
But for things that were beneficial to him, he naturally whole - heartedly agreed.
Just when he thought he could rest, Haruki placed green chakra on his body.
The fatigue in his body disappeared instantly.
"Come on, Kakashi."
"..."
Kakashi grimaced and started his running exercise again.
This repeated several times.
By evening, Kakashi collapsed on the ground.
Everyone has their limits.
To prevent him from being unable to rise the next day, Haruki used a regular [Healing Jutsu].
Chakra appeared in his eyes, and he could see Kakashi's physical condition clearly at a glance.
"Kakashi, how are you?"
Haruki withdrew his chakra, asking while thinking about what medicinal herbs to buy to nourish his body.
Training warriors or [Ninjas] consumes a great deal of resources.
Although [Ninjas] in the [Naruto] world are naturally strong, there is a limit.
It's impossible to over - train without end.
Kakashi didn't want to talk. After a moment, he said weakly, "I don't even want to move a single finger."
"This means the training was effective."
Haruki waited for a moment and then asked him to get up.
The two didn't return to the [inn] immediately.
To Kakashi's astonishment, Haruki spent tens of millions to buy all kinds of rare tonics.
"Teacher, are these all for me to eat?"
Kakashi glanced at the dazzling array of medicinal herbs. He always felt that his future days would be tough.
These things didn't look good to eat at all.
"Yes. You're still young and your body isn't fully developed. To avoid causing damage to your body, I'll provide you with medical treatment according to your condition."
After paying the [inn] [boss], Haruki requisitioned his kitchen.
Although he wasn't a traditional Chinese doctor, he was at least a [Medical Ninja].
He could be considered a doctor with superpowers.
Near midnight, a bowl of black potion was ready.
"..."
Kakashi's face was full of protest.
He knew that Haruki was a great cook, but decocting medicine had nothing to do with [cooking skills].
It all depended on the medicinal herbs themselves.
Unfortunately, most medicinal herbs had a very peculiar taste.
"Drink it, Kakashi."
Haruki lifted his eyelids. For some reason, he really wanted to laugh.
Sure enough, human nature is inherently evil.
He subconsciously derived pleasure from others' pain.
Kakashi closed his eyes and gulped it down.
After finishing, he opened his mouth and stuck out his tongue like a dog.
It was both hot and numb.
Haruki patted him on the shoulder and said with a smile, "Have a good sleep."
He returned to his room.
Tsunade was already asleep.
However, when he opened the door, she woke up again and mumbled, "You're back."
Haruki walked to the bedside, knelt down and kissed her forehead. "Go back to sleep."
He still had some things to do.
He sat down at the table and took out a notebook.
[Report on the Social Survey of the Ninja World]
Haruki wrote it like a diary, first recording what he saw and heard. He would summarize it after returning to [Konoha].
The first topic was to put an end to gambling.
It was his feeling after going to the [casino] with Tsunade.
It's true that one should stay away from porn, gambling, and drugs.
Of course, the so - called "porn" between husband and wife was an exception, as it was legal and compliant.
One shouldn't mess with other men's wives.
Speaking of which, the nicknames of the [Sannin] of [Konoha] are related to porn, gambling, and drugs.
They completely failed to abide by the [Ninja] code.
Haruki thought there were many aspects of the [Ninja] code that were worth learning from.
The second installment is about Kakuzu.
Don't act impulsively. Make sure you're well - informed to avoid getting into a bind.
The third installment is set at sea.
The fish is unpalatable.
The fourth installment is supposed to be set in the Land of Iron, but it hasn't been started yet.
Haruki plans to train Kakashi before meeting Mifune.
Of course, he doesn't want Kakashi to challenge Mifune. It's pointless and just a suicide mission.
Although Mifune isn't as strong as he was during the Fourth Great Ninja War, he's still on par with any Jonin.
Just then, Haruki looked up and went to the window. In the far distance, on a rooftop, a Ninja was dashing.
A Ninja?
It's quite rare to see a Ninja in the Land of Iron.
Haruki pondered slightly. Maybe the Ninja was from the neighboring Taki Hidden Village.
When he thought of Taki Hidden Village, his first reaction was the Tailed Beast.
To be honest, it's quite amazing that such a village has a Tailed Beast.
