Surya decided to find water for Hashira, but he was worried that if he explicitly asked Hashira to train him, he would be kicked off the mountain. Most importantly, he cannot try other breathing techniques. Surya called his breathing technique the Infinite breathing method.
Around noon, he went directly to a nearby town and looked for a house with a wisteria sign. This house has served the demon slayers as a token of gratitude for saving them. A middle-aged guy received him inside the house, and Surya explained what was going on. That man instructed him to rest, and the following day he saw Sakonji Urokodaki, a former water pillar. Surya explained his condition, and Sakonji agreed to his terms.
*****************************
"Your training will be at Mount Sagiri; keep up with me."
Sakonji began sprinting along the road. Behind him, Surya began to pursue him. It took about half a day to reach Mount Sagiri. Surya's performance surprised Sakonji off guard. Throughout his journey, he saw that the Surya breathing method remained constant.
"Get some rest today; your training will begin tomorrow."
Surya wanted to question him about why he accepted his condition. All he remembers is that Sakonji was picky about disciples. Surya chose to focus on his training for the time being.
Surya's training began the very next day. Sakonji first led him to the top of the mountain and instructed him to descend. The entire mountain was shrouded in fog, and Surya was struggling to breathe, but he persisted. There were various traps in the mountain. Pits, rock flinging, and many types of tarps.
He was slightly hurt during the first week, and training progressed gradually. He also descended the mountain with the sword in his hand, avoiding all the traps. This type of exercise increased Surya's strength by ten times. Sakonji was likewise pleased by the development and felt he had discovered a jewel.
"Today, I'll explain the breathing method."
"I've noticed you already have a breathing method."
"Yes, Urokodaki-san."
"I don't ask anything about it."
"Now I'll demonstrate my breathing method. So, pay attention.
Surya observed Sakonji, who diligently executed all breathing techniques. Water Breathing is a Breathing Style that imitates water, specifically the fluidity, flexibility, and adaptability of the liquid, through the user's movements, techniques, and skills. Most, if not all, known techniques require the user to bend their body, arm, and weapon in a continuous manner to mimic the movements of rushing or flowing water.
Surya benefited much from observing Sakonji's breathing techniques. Surya has the confidence to develop new methods, even though he currently lacks them.
Sakonji also discussed the demons and the Demon Slayer group. The new demon slayer's selection two months two months later. Surya decided to enhance his training.
*********************************
Surya examined the boulder, which had been ripped into pieces by his newly created move. He derived the new from the water element.
"Two months have already passed. It is time to attend the selection."
Surya moved carefully down the mountain, and he heard a faint voice behind him.
'Brother, please kill the demon and be safe.'
Surya knew who they were and turned around. He just noticed small shadows in the fog and nodded at them. He knows who they are and wants to talk to them, but they have only been watching him from the shadows up until now.
This is mainly due to his Infinite breathing technique. This technique is extremely harmful for all types of evil things. Although they were most likely souls, there could be some effect on them. In two months, he had an in-depth understanding of the technique.
The infinite breathing method constantly draws energy from the atmosphere, strengthening his body. That energy is most likely derived from sunlight. If he were in a magical or spiritual world, his physique would have grown several hundred times stronger.
It also absorbs all negative substances in the body, including poison. His recuperation time and healing speed are likewise remarkable.
"It appears you've created a good move for your breathing technique."
"Yes, Sakonji-san."
"Good, I've arranged everything for your journey."
"Sakonji-san, why did you accept my conditions?"
"My disciple, Giyu, told me about you."
Surya was surprised to hear Sakonji's words.
"Giyu was the one who went after the demon."
"After discovering that you had killed it, he looked into it and instructed me to train you."
"Maybe he recognized your potential."
Surya was also startled to hear it. He expected that the demon Salyers would look into it sooner or later, but he was astonished that Giyu did. According to Sakonji, Giyu joined Demon Slayers a year ago.
"Thanks, Sakonji-san." Surya bowed before him.
"It's fine; if you have time, please look after Giyu."
"I am confident that you will become a new Hashira in no time."
"Rest well tomorrow; you'll have a long travel."
Surya also nodded.
**************************
Surya left the next morning towards Mount Fujikasane. The mountain is utilized by the Demon Slayer Corps for the Final Selection when individuals aspiring to become official Demon Slayers can demonstrate their abilities. The examinees who pass will be acknowledged and given their own Demon Slayer Uniform, Nichirin Sword, and Kasugai Crows.
To assure the success and expertise of the crop of Demon Slayer candidates, the Mountain itself houses a significant number of demons captured by past Demon Slayers and used to test the applicants' survival and combat skills.
The mountain's dense growth of Wisteria trees has transformed it into a massive prison for demons. The Wisteria trees keep demons from leaving the mountains, forcing them to starve until the Final Selection.
Surya also obtained some information from Sakonji-san. Currently, there are four Hashiras: Flame Hashira, Stone Hashira, Sound Hashira, and Flower Hashira. With this information, he may be certain that the plot has not begun. The Demon Slayer organization is currently understaffed as a result of several Previous Hashira retired.
In the evening, Surya arrived at Mount Fujikasane, which was completely covered in wisteria trees. The entire mountain was stunningly lovely. He knows in that mountain Demons are waiting for their prey.
