"Really!" Izuna immediately stopped the action of condensing chakra and looked extremely excited. "Then teach me some more, big brother! The Lightning Release you used before was so awesome! Teach me Korega!"
Ling shook his head slightly. "That's not possible."
"Eh - Please teach me, big brother - I tested my attributes before. I also have the lightning attribute. I can learn it!"
Ling could almost imagine his younger brother's disappointed expression. While finding it funny, he also felt a bit of regret, but he didn't change his words. He just softened his voice. "It's different, young Izuna. It's not that big brother doesn't want to teach you, but you can't learn it yet, young Izuna."
Izuna tilted his head in confusion. "What's different? Why can't I learn it?"
"Well, Izuna also knows that chakra is classified into five attributes: wind, fire, water, earth, and lightning. If there isn't the corresponding attribute of chakra in the body, one can't learn the corresponding attribute of ninjutsu."
Ling reached out and gently tapped Izuna's forehead, speaking gently. "But besides that, there's also another extremely important point, which is one's own chakra amount. When the power of ninjutsu remains constant, Lightning Release ninjutsu consumes more chakra and has higher requirements for the body.
Moreover, Izuna doesn't have enough chakra at present to release that ninjutsu."
Izuna wasn't the kind of person who would keep making a fuss just because he couldn't get what he wanted. After getting an explanation, he was just a little disappointed and didn't keep bugging. Instead, he turned his attention to another question. "Then how much more chakra do I need to learn that super cool ninjutsu?"
"Well—for safety reasons, you need to at least increase your current chakra by twenty times. Moreover, Izuna, you also need to learn nature transformation and fast hand - seals..."
"You also have to continue improving your physical fitness. You won't be able to use it smoothly with your current constitution. After all, that ninjutsu was second - developed by me, so it suits me better. The requirements will be a bit harsher for others to practice."
Izuna opened his cat - like eyes wide. "Eh—? Twenty times?"
"Yeah, Lightning Release also has high requirements for the body. You see, big brother recovers quickly after each mission, right? That's all thanks to big brother's continuous hard training. You need a strong body to use cool fighting methods."
Izuna, who had just started learning about chakra, was completely confused. He lowered his head and started counting on his fingers. His voice even sounded as if he was questioning the meaning of life. "Twenty times more chakra, more physical training, learning nature transformation and fast hand - seals... Is it really that hard to fight coolly?"
"Well—Izuna, you don't need to be in a rush. When you get a little older, your body will be able to condense chakra more easily. For now, it's better to focus on improving your physical fitness and practicing hand - seals."
Ling softly laughed and reached out to ruffle his little brother's hair. "But there are also things you can learn now. If you work hard at it, you'll be far ahead of your peers in the future."
Izuna immediately perked up and grabbed Ling's arm. "What is it? Is it also cool?"
Ling tilted his head back, his voice a bit hesitant. "Well—should be. After all, this is a skill that is supposed to be learned after hand - seals."
"Then I want to learn!"
"Haha... Okay, but remember to be careful when you practice, all right?" Ling stood up, leaned on his blind stick, and felt his way to a wall. "Watch closely."
After Izuna responded, he fixed his eyes on Ling. He saw Ling take off his shoes and step on the wall, then slowly walked up along the wall. Finally, he stood firmly on the wall.
Izuna had seen other clan members run up the wall in a few steps and then dash along the rooftops, but he rarely saw someone stand on the wall parallel to the ground in such a leisurely manner. His eyes immediately lit up. "Is this also done by using chakra?"
"Yeah, but it requires high - level chakra control. Izuna, you can put a cushion under you and practice on the big tree in the yard."
Ling turned around, slowly walked down, and sat down beside Izuna again. "During missions, we always encounter all sorts of bad environments. The ground beneath our feet isn't always solid. There are muddy swamps, slippery moss, and water surfaces with no footholds..."
"When we encounter such situations, we must condense our own chakra under our feet to provide ourselves with a place to stand, so as to better unleash our combat power."
Izuna tilted his head. "Why can we use chakra to move steadily in those places against the normal rules? Is it because we use chakra to form a plane to stand on?"
"No, a more accurate way of putting it is that we use chakra to attach ourselves to those objects, tricking them into thinking that we are the same kind of substance as them. Chakra also evenly distributes the weight of our bodies. That's how we achieve the goal of stability and supporting our bodies."
"And different places require different amounts of chakra. The more unstable the ground beneath our feet is, the more chakra we'll consume. We have to make timely adjustments to move freely. However, the chakra consumed in this kind of movement is negligible compared to that used in releasing ninjutsu, so there's no need to worry too much about running out of chakra because of this."
"So, at your age when you have relatively less chakra, it's better to do this kind of practice than to learn ninjutsu. It can give you better training. I'll tell you some key points next. If you don't understand anything, ask me at any time. Don't hide it, okay?"
"Yeah! I'll definitely listen carefully and ask when I don't understand!"
When Madara came out after tidying up the house, he saw his big brother barefoot in the yard, raising his hand to guide his younger brother up the tree step by step.
A smile involuntarily appeared on his lips, and he slightly raised his voice. "Big brother, are you teaching Izuna the skills of climbing trees and walking on water?"
"Yeah," Ling maintained a semi-squatting position and always held his arms loosely about a palm's distance from Izuna. "Our Izuna is very talented. He can already walk steadily for seven or eight steps now."
"Eh - so Izuna is really great?" Madara also walked into the yard with a smile. "I could only take three or four steps at this age."
Just as Madara was speaking, Izuna slipped and fell again. Ling caught him and hugged him up smoothly. "Not bad. Our Izuna walked ten steps this time."
"How on earth can I channel chakra under my feet?" Izuna's little face looked puffy with anger. "If I use too little chakra, I can't stand on it. If I use too much, my foot gets stuck and I can't lift it, and I might even get bounced off. And there's also a feeling of losing my balance when standing on it... Korega is so difficult!"
"Haha, this is normal. It took me a whole day to learn it back then." Madara laughed. "But there's a trick to it. At first, you can try to sense it with your hands. After you roughly figure out how much chakra to release, then switch to using your feet. In this way, even if you don't walk steadily, you're less likely to fall."
Izuna's eyes sparkled with excitement. Just as he was about to say something, Ling interrupted him with a smile and said, "Wasn't it because Madara fell from a tree into the water, couldn't swim, and the adults were nowhere around that he accidentally learned Korega?"
Madara blushed. "Big brother! You don't need to mention that!"
"Hahaha, it doesn't matter! I learned Korega because I was being naughty and climbed too high, and then I couldn't get down. I had to learn it to get home on time." Ling burst out laughing, holding Izuna in his arms. "I was so clumsy when I first used this technique, flailing my hands and feet everywhere. What you guys did is nothing compared to that."
