Starting Training

One night has passed...

Rio naturally woke himself up at dawn, he was used to getting up at dawn, so he didn't need an alarm clock to wake him up from sleep.

"You're awake Rio."

"Good morning Jigoro Sensei."

Kuwajima Jigoro nodded slightly as a greeting, he continued to stir the soup in the cauldron.

Rio raised his right hand to cover his yawning mouth, moved his neck left and right, a 'Crack' sound came from his stiff neck.

Then he walked out of the hut, he immediately felt the cold winter morning temperature.

"Huhhh... It's so cold, it's my first time seeing real snow."

Rio noticed that there was white dew as he spoke, this was a new experience for him. He has no experience of traveling abroad and indonesian is a tropical country that only has two seasons, namely summer and rainy season.

Walking to the wooden bucket of water beside the hut, he scooped up water with both palms and put the water in his mouth to rinse his mouth.

After gargling, he washed his face with cold water which instantly made him fully conscious.

"The sense of taste, sense of touch, and sense of smell prove this is all real."

"Even though I'm in an anime, but it doesn't feel 2D at all, it feels very real and there's no difference with 3D."

"The Reincarnation Room is really mystical to be able to bring humans into anime..."

Staring at the snow-covered surroundings like a white blanket, Rio wouldn't believe this was all 2D if he didn't know.

Rio went back into the hut, he was greeted with the fragrant aroma of the soup in the cauldron.

Jigoro poured soup into two bowls, he handed one to Ren.

"Eat breakfast before starting today's training, you will need a lot of stamina while training."

"Thank you Jigoro Sensei."

Sitting in front of Jigoro, Rio took a bowl. When he saw that the soup was only broth and some vegetables such as potatoes and sweet potatoes, he didn't complain.

Apart from not being a picky eater, he didn't expect much from the variety of food in the Taisho era.

When Rio was about to sip the soup with a wooden spoon, his hand hurt when a small pebble hit his hand.

"Where are your manners, at least say Ittadakimasu before eating."

"Sorry Jigoro Sensei, there is no such custom in my country."

"Rio, since you have become my disciple, it is my duty not only to teach you how to exterminate demons, but also to teach morals and manners so that you don't take the wrong path."

On the surface Jigoro looks like a fierce old man, but he has an unwavering dedication to raising his disciples, he doesn't want his disciples to choose the wrong path one day.

"From now on, before eating you must say Ittadakimasu."

"I understand Jigoro Sensei."

Rio nodded, as long as it didn't harm him, he obediently accepted Jigoro's teachings.

"Ittadakimasu!"

Putting their hands together, the teacher and disciple started their breakfast.

Rio and Jigoro walked up the hill, the gust of cold wind didn't stop their footsteps.

Jigoro led the way in front, wearing only a yukata on his body, he walked steadily without caring about the cold wind in winter.

But Rio couldn't, his body shivered, his teeth chattered, his eyebrows and hair even hardened from freezing. Even in such a state, he did not let out any complaints and his expression was always indifferent.

Jigoro glanced back from time to time, he was amazed by Rio's determination to endure this extreme cold without uttering a single complaint.

"Rio, have you remembered the Thunder Breathing Style pattern I gave you last night?"

On the way to the top of the snowy hill, Jigoro asked.

"I have it memorized, sensei." Rio nodded slightly.

Last night, Jigoro handed Rio a scroll containing the Thunder Breathing Style method. He was required to memorize the Thunder Breathing Style method before morning.

And to Rio's surprise, he was able to recall the extremely complicated method of the Thunder Breathing Style in just 30 minutes. He guessed it was because his high INT 20 stats allowed him to have a strong memory.

"That's good, Thunder Breathing Style is a Breathing Style that imitates lightning, specifically lightning-like fast attacks and moves that pierce the sky, and replicates them with the user's moves, techniques, and abilities."

"This Breathing Style focuses on transmitting force to the user's legs, and maximizing the output of each muscle and blood vessel within it."

"And to be able to use the Thunder Breathing Force, a strong body is required for the user to withstand air pressure, air resistance, and gravity."

"So now you need physical training to improve you physical quality."

"We have arrived."

The two of them arrived at the top of a hill which was completely covered in thick snow.

"Huh huh huh huh..."

Rio felt difficulty breathing once he reached the top of the hill and his chest felt tight.

Seeing Rio who was having a hard time breathing, Jigoro wasn't surprised by this and started his teaching.

"In the highlands, the oxygen levels are lower than the lowlands, so humans living in the highlands adapt to low oxygen levels."

"Rio, from now on you should get used to breathing here with the Thunder Breathing Style."

"Flow oxygen throughout your body, control your breathing!"

"Your practice now is to come down from this hill and then back up this hill, repeat this until the sun goes down."

"Are you up to it?"

Jigoro gave very tough training for beginners like Rio.

"I'll do it Jigoro Sensei!"

Rio who started breathing with the Thunder Breathing Style method answered without changing his expression.

Jigoro was used to his disciples not being able to show his expression, he nodded in satisfaction.

"There is one more thing, on this hill there are many traps, be careful to trigger traps when going down the hill."

After saying that, Jigoro descended the hill leaving Rio alone at the top of the hill surrounded by pine trees covered in snow.

"Trap… This won't be an easy training."

"Before going down the hill, I better get used to breathing with Thunder Style Breathing…"

Rio didn't rush down the hill, he sat cross-legged under a pine tree.

He practiced the Thunder Breathing Style first to get his body used to breathing in the low oxygen levels at high altitudes.

"Huhhh.... Hahhh... Huhhh... Hahhh..."

Inhaling, then exhaling, Rio repeated this cycle many times.

Without realizing it 2 hours have passed...

Due to the falling snowflakes, Rio who was sitting quietly under the pine tree had now become a snowman.

For 2 hours, he just sat while catching his breath. If it weren't for his chest rising and falling indicating he was still alive, he was like a frozen dead man.

"After mastering Thunder Style Breathing, breathing becomes a lot lighter."

Rio opened his eyes, now he doesn't feel short of breath like 2 hours ago when he arrived.

Now he can breathe normally as if he was not at high altitude.

As soon as Rio stood up, the snow that had accumulated on his body and his body shivered with cold.

"Huhuhu… Even though breathing is no longer difficult, I'm still cold."

"I'd better start down the hill to get my body warm again."

With this the training hell begins!
