Chapter 51 - 51: The Strongest Summoning Beast

"Oh? What kind of Ninjutsu?" Tsunade also looked over at his words. Recently, unable to go out gambling, Tsunade was too bored, so she patiently taught Kushina and Rinka. As for Kazuki, he was temporarily overlooked by her. She felt that besides Medical Ninjutsu, she didn't have much else to teach Kazuki. As for the Yin Seal, she wasn't sure if Kazuki could learn it. It was tailor-made for her, and girls could learn it, but for a boy like Kazuki, it would be very difficult. "Guess." Kazuki looked at Tsunade mysteriously, then pulled out two kunai from his backpack, gripping them with both hands. Under the gaze of Tsunade, Kushina, and Rinka, the characters "World Peace" appeared on the kunai. "This is? A Flying Thunder God Mark? You've mastered the Flying Thunder God Technique?" Tsunade looked at Kazuki in disbelief. Tsunade had some understanding of the Flying Thunder God Technique. Like Hiruzen and the others, she had also studied the Flying Thunder God Technique back then. Unfortunately, like everyone else, her spatial perception was only average, better than ordinary people, but far from reaching the standard for learning the Flying Thunder God Technique. Although she had some expectations for Kazuki before, she felt the success rate wouldn't be too high, and even if he did master it, it probably wouldn't be usable in a short time. She didn't expect Kazuki to actually succeed in learning the Flying Thunder God Technique? "It's not a complete success yet. I've solved some key issues, but it might still take some time to truly apply it in combat." "I need some battles to adapt, because as you know, in high-level combat, the difference is often just a tiny fraction. One careless mistake, and the enemy isn't killed, but I die instead." Kazuki frowned and said, "Even if I truly master the Flying Thunder God Technique, for now, I can only use it for travel." "That's already very impressive." Tsunade mumbled. She already knew Kazuki was a genius, but she hadn't expected him to actually learn the Flying Thunder God Technique. If her granduncle knew about this, he would probably question life itself. After all, the Flying Thunder God Technique was definitely one of the most difficult Ninjutsu in his mind. It is said that when Tobirama created the Flying Thunder God Technique, he spent at least ten years. "Kushina, Rinka, you two should take these. If anything happens in the future, I can come to your side immediately." Kazuki instructed. "Unfortunately, I don't have chakra metal, so you can't use Chakra to activate the Flying Thunder God Mark on them." "Otherwise, if you encounter danger, as long as you activate the mark on them, I can come over." Tsunade said regretfully, "Chakra metal is hard to find. My grand-uncle didn't seem to forge many Flying Thunder God kunai back then, and they were all left in the Land of Lightning." "They won't return the kunai to us either." "And you gave them to Kushina and Rinka. Why didn't you give one to me?" "Sure enough, I, your teacher, have no standing in your heart, do I?" She felt like she was going to be infuriated. Kazuki was too heartless. She had poured her heart out to him, teaching him her super strength and Medical Ninjutsu. The Sword of the Thunder God was also something she specifically asked Hiruzen for to strengthen Kazuki's power, seeing his interest in Lightning Release. After that, she even gave him the Flying Thunder God Technique. Her grandmother, Mito, was willing to teach Kazuki, at least half of that was probably due to her influence, right? But what about Kazuki? After learning the Flying Thunder God Technique, he didn't even give her a kunai, this was too heartless. Could it be that she wasn't good to Kazuki? "No, it's not that. You probably don't need me to protect you for now, do you?" Kazuki looked at Tsunade somewhat exasperated. "Ultimately, these two kunai are temporary. Later, I still need to find a way to create those special Flying Thunder God kunai." "Hmph!" Tsunade crossed her arms and turned her head away, clearly not satisfied with Kazuki's answer. Kazuki pointed to Kushina and Rinka beside him and continued to explain, "Alright, in my opinion, you don't need my protection, they do." "Aren't we going to fight strong enemies later? Providing them with some assurance is reasonable, isn't it?" "You said before that if we inject chakra to this kunai, you can immediately rush over, is it very difficult to forge?" Rinka asked while playing with the kunai in her hand. Kazuki quickly explained, "It's not that I can immediately rush over, but rather that when you inject Chakra, I can sense it immediately, and then use the Flying Thunder God Technique to get to you." "Of course, whether I come or not still depends on whether I'm willing." "If it's too far, I can't sense it." "It's pretty much like a summoning beast." Rinka glanced at Kazuki. Although it depended on whether Kazuki was willing, if it could really be done like that, it would be a safeguard for her. Kazuki definitely had strength comparable to a Jonin, he just hadn't shown it normally. Kazuki's face instantly darkened and he said, "I am not a summoning beast." "When my grand-uncle first created the Flying Thunder God Technique, he got the inspiration from summoning beasts." Tsunade's lips curved into a smile. Rinka was a very interesting child. Tsunade liked it when Kazuki was put in a difficult position. Later, she could secretly spread the word that Kazuki was the strongest summoning beast, which would definitely put Kazuki in a difficult position for a while. That would be quite interesting. "So, does that kunai require chakra metal?" Rinka asked, gazing at Kazuki. "Yes, if possible, chakra metal is the best choice." "If there's no chakra metal, a good special refined iron could also work, but Chakra transmission would require more consumption." Kazuki thought of chakra metal and felt a pang. He had money, that was true. Kagami had left him a considerable inheritance, and he had completed many missions during this time, so Kazuki was quite wealthy. But even with so much money, he couldn't buy much chakra metal. The entire Konoha didn't have much chakra metal in stock. "The Hyuga clan does have some chakra metal. I'll get it for you after I go back." Rinka nodded thoughtfully. "Then thank you very much." "No need to thank me. Anyway, the kunai that are forged will be in my hands, so they're actually mine." "…"
