After hours of meditation, with eyes closed, Madara released his qi, enveloping his body with it, then gradually infusing it with lightning elements. Once he achieved this, he applied his comprehension of the shockwave technique.

As he applied his learning, Madara opened his eyes, gazing at his transformed body. He noticed a change in the lightning element surrounding him, which had become a vibrant yellow, accompanied by frequent bursts of lightning strands throughout his body. Madara smiled at the sight. To test his technique, he needed a living target.

Scanning his surroundings, Madara spotted a green frog near the waterfall. Slowly rising from his seated position, he prepared to approach. However, as he was about to take a step, he noticed his lightning qi gradually fading away from his body. This made him pause in his tracks to observe it.

"It seems like I need to maintain this technique while I move or act."

He sat down again and repeated what he had done earlier. After finishing, he slowly stood up and walked in the direction where he saw the frog while maintaining the release of lightning qi throughout his body. As he approached the riverbank from the waterfall, he searched again for the green frog. When he spotted it in the distance, Madara carefully approached, finding the frog with its back turned to him. Without wasting time, he quickly grabbed it with his right hand and said,

"Shockwave!"

As he uttered those words, a fast yellow lightning strand release from his body towards his right hand. Because of that, he electrocuted the frog. Despite the shock, the frog convulsed but did not die; instead, it became immobilized due to his technique.

When he saw this, Madara placed the frog on a nearby rock where he was standing. Because he used qi from the technique he employed, he sat on the rock near the frog in a meditative position to replenish the qi he had used. Once Madara felt he had recovered from the depletion of his qi, he opened his eyes again. Upon opening his eyes, he found the frog still unable to move, so he continued observing it.

While observing the frog, he spoke softly, "From what I recall, it's been 30 minutes and it still can't move."

Because of this, he focused his observation on the frog, and after a few minutes, it began to move slowly from its position. When it finally moved, it jumped in another direction. Upon witnessing this, Madara furrowed his brow as he watched the frog move away.

"Based on my estimation, it's been immobile for about an hour. Adding to that, I couldn't sense the cultivation level of the frog, so it seems it's only at the body tempering realm. This means the duration of immobilization depends on whether the target is cultivating or not."

Madara let out a sigh as he sat down. After a while, he stood up again and resumed his training. After a few hours, he successfully maintained the shockwave technique while walking or moving. 

Noticing that he finished early, he decided to continue his training with his cutting technique. As he observed the sun starting to set, he went to find Li Lu to head home.

When Madara returned home, he had dinner and then went to his room to change clothes. After changing into his new clothes, he lay down on his bed, reminiscing about the training he had undergone to learn the techniques he had chosen. Despite the short time, Madara smiled as he recalled that he had managed to reach the initial stage of all the techniques he had selected. Before he fell asleep, he remembered that his sister would be returning the next day.

Initial Stage: This is the basic stage where the practitioner learns the fundamentals of the technique. They may struggle with control and precision, but they can still produce some effects.

The next morning, after showering and grooming himself, Madara headed to the dining area and noticed that breakfast was served with a letter beside it.

"Madara, continue practicing with Li Lu. I'll take a short nap and will join you later. Your sister, Xiao Yun."

Upon reading the note, he quickly went to his sister's room. Upon entering, he saw his sister soundly asleep after her long journey. Madara couldn't help but smile as he watched her sleep. After leaving her room, he returned to the dining area to write a note in response to his sister's message.

"Sister Yun, please rest first. Li Lu and I are okay, and don't worry, I will protect her," Madara thought as he wrote on the paper.

After that, he left the note in the dining area and went out to train. As he left the house, he saw Li Lu waiting for him.

"Good morning, Madara."

He responded to Li Lu's greeting, and they both walked towards the training area. While walking, Li Lu asked Madara if Sister Xiao Yun had returned. Upon hearing this, he replied,

"She's back now, but she's tired from the journey, so she's resting in her room and asking us to continue our training."

Li Lu simply nodded upon hearing this from him. When they reached the training area, they resumed their training on their techniques. After a whole day of training, when Madara returned home, he saw his sister setting up dinner. Because of this, Xiao Yun paused what she was doing and invited his little brother to have dinner. While eating, she asked him what happened while she was away.

"It's nothing new, Sister Yun. Li Lu and I just trained all day," Madara replied with a smile to his sister.

Seeing and hearing Madara's response, Xiao Yun simply nodded, and they continued their meal. The next day, at the training area, Xiao Yun set up two dummies again to teach and guide the two youngsters on how to use a sword with one hand while employing their cutting technique. While the two practiced, she moved around them, observing their actions, and after several hours, they finished their training. After they were done, Madara looked up at the sky and realized it was still early, knowing they had time for the next training session. Out of curiosity, he asked his sister.

"Sister Yun, what will you teach us next?"

Upon hearing this, Xiao Yun smiled sadly and replied, "To be honest, I have nothing more to teach you."

Seeing the disappointment on the faces of the two youngsters, she spoke again.

"Don't worry, remember the book I gave you? It contains all the basic sword techniques and guides you'll need."

"As we cultivators advance our cultivation levels, we often experience improvements not only in physical strength and martial prowess but also in mental faculties such as perception, concentration, and memory."

"So, you won't have to worry about memorization anymore. The only obstacle when learning a technique is comprehension or understanding of a technique."

After Xiao Yun finished explaining, Madara asked her with a hint of sadness in his voice, "Sister Yun, in that case, what will you do now?"

Xiao Yun couldn't help but smile upon hearing this from Madara. "I will collect herbs, and Li Mei will accompany me to gather medicinal plants because we haven't saved enough money to buy techniques that match your nature affinity."

Upon hearing this, Li Lu smiled at her older sister and said, "Big sister Yun, thank you for everything. We don't know how to repay your kindness."

Xiao Yun just smiled at what she heard from her. "You don't need to think about that. Just seeing you achieve your dreams makes us happy."

"But Sister Yun, can I come with you to gather medicinal plants?" Madara asked.

Xiao Yun shifted her attention to him. "I'm sorry, Madara, but you can't. Even if I wanted to, you need to continue your training with Li Lu."

Because of that, he didn't pester his sister anymore.

"Big sister Yun, where are you and mom going?" Li Lu asked her.

Because of Li Lu's question to her, she drew on the ground using her sword. When it was over, there was a circle, and inside it were houses. Then she explained it to the two children.

"These houses represent our village. In the north, here we will try to look for medicinal plants."

After that, she pointed out their location. "Your training area can be found here in the southern part of our village."

When Madara heard this, he asked, "Sister, do you know the name of the forest surrounding our village?" Madara gestured his index finger with a circular motion towards the drawing, as their village was surrounded by tall, lush trees.

"Yes, I know, and as far as I know, it's called (Yúnwù Sēnlín) - Cloud Mist Forest."

"Big sister, when will you leave?" Li Lu asked her.

"Tomorrow, Li Lu." Upon hearing this, Madara also asked his sister, "Sister Yun, when will you return?"

Xiao Yun placed her hand on her waist while furrowing her brow in thought. After a few seconds of pondering, she answered. "I think it will take us about three weeks to search for herbs and medicinal plants."

After that discussion, they headed home early. And the next morning, Xiao Yun left various ingredients and food that would last for three weeks. Along with these was a small notebook containing guides on cooking. When Madara read it, he could only gulp and mutter.

"I don't know how to cook; all I know is to eat."

Seeing his reaction, Xiao Yun laughed and gently patted Madara's head. "You need to learn that too."

Madara remained silent, and instead he focused on the items he would bring for training. After preparing, Madara and Xiao Yun left their house, and upon exiting, they saw Li Lu and her mother, Li Mei, waiting for them.

After exchanging pleasantries, the two bid farewell to them. As the two moved away, Madara and Li Lu began walking towards the training area. After hours of walking, they reached the training area. Upon arriving, Li Lu went to the top of the waterfall, while Madara headed to the grassy training ground below.

As he approached the training ground, he began his training.

....

After three weeks of training.

....

As the sun began to set, Madara decided to add one more training session. Standing in the middle of the training ground, he faced a dummy. Without hesitation, he utilized the Wooden Clone Technique using his mind. After its activation, a figure emerged behind him. It looked exactly like him in terms of physique, clothing, and hair, and even the facial expression mirrored his own emotionless demeanor.

As the wooden clone emerged, it quickly released qi from its feet and swiftly ran towards the back of the dummy. Meanwhile, Madara moved slowly towards the dummy. While doing so, he uttered, "Fireball."

He released it from his mouth effortlessly, not needing a deep exhalation, as if it were a natural action for him. The fireball hit the dummy directly, causing it to skid backward. Seeing his attack connect, Madara then used the Body Flicker Technique. Then, releasing Qi from his feet, he disappeared from his position and reappeared in front of the dummy in a blink of an eye, which was still skidding backward. Sensing that he was still mid-air, Madara swiftly executed a 360-degree right kick towards the dummy.

Due to the speed and power of his attack, the dummy was propelled towards his wooden clone. As the dummy approached the clone, Madara quickly commanded his clone mentally to release Qi from its right hand to punch the skidding dummy approaching. Following Madara's command, his clone punched the dummy with force, sending it back towards him.

Upon landing from his mid-air maneuver, Madara looked at the approaching dummy. As it came closer, he attempted to halt its advance using his right hand. With his action, he began to step back while trying to stop the skidding dummy. Once he successfully halted the dummy's progress, he quickly released lightning qi from his right hand and exclaimed, "Shockwave."

Upon being electrified, the flaming dummy was shocked. Seeing this, Madara quickly grabbed his wooden sword from his waist. As he retrieved it, he swiftly released sword qi and swung his wooden sword to the right, hitting the dummy. Upon impact, the dummy split vertically and fell to the ground.

Seeing this, he smiled and said, "Finally, all the hardship was worth it."

Afterward, his wooden clone returned to his body. Then he took a cup from his sack to fetch water from the river to extinguish the remaining fire on the dummy. Afterwards, he retrieved the paper containing his technique from inside his clothes. After retrieving it, he released fire from his left hand and burned the paper.

While doing this, he muttered, "For security purposes, it's better if others don't see or read the contents of this paper."

Once the paper turned to ashes and disappeared from his palm due to the wind, he sat cross-legged and meditated to restore the qi he used during training.
