He hadn't finished selecting items yet, so Torifu temporarily suppressed his thoughts and continued to see if there were any useful items. He also tried to refresh the list, wondering if other flesh-and-blood type items would appear. But after refreshing for a long time, he didn't encounter any more flesh-and-blood items. Torifu didn't pay it much mind; after all, it had taken twenty years to only find three such items. His current attention was focused on the item before him, which seemed perfectly suited for Konan's use.
[Source Matter, 100,000 Peace Points] (Select any substance to be a constant item. Once selected, the Source Matter will continuously absorb chakra to produce that constant item, and its quality will increase severalfold.)
Seeing this item, Konan was the first person Torifu thought of. The paper Konan used for her ninjutsu didn't appear out of thin air; she carried it with her. Moreover, its quality was relatively low, merely paper treated with oily substances, making it harder and waterproof. It had virtually no other advantages. Therefore, even though Konan had already developed B-rank ninjutsu, her offensive power remained weak. But this Source Matter could solve that problem. Without a second thought, Torifu paid directly. Putting everything else aside, he simply had a lot of money.
A flash of white light passed, and a greenish-blue, orb-like object appeared in Torifu's hand.
"This is the Source Matter, it's quite amazing."
He first put away the Source Matter and walked to the training posts where the two of them practiced, taking a fresh sheet of white paper. This was the kind of paper Konan typically used.
"Master, what are you doing?" Konan asked, puzzled, but Torifu merely waved his hand. "It's nothing. I need to conduct an experiment. If it succeeds, you'll be very happy." Konan was curious after hearing this, but didn't stop her training.
After Torifu returned to his reclining chair, he chose to face away from Yahiko and the others and took out the Source Matter from his ring. Holding the white paper in his other hand, he mused, "What would happen if I injected chakra into the paper? Would it stabilize along with the chakra?"
Overthinking was useless, so he proceeded directly to action. Pale blue chakra was injected into the paper. This chakra was very weak and wouldn't damage the paper. Instead, it continuously swirled around the white paper, similar to how chakra is infused into ninja tools. Then, Torifu fed the white paper, imbued with a faint wind-nature chakra, to the Source Matter.
Almost instantly! The Source Matter absorbed the white paper, along with that wisp of weak chakra. Torifu rejoiced at the sight, and then watched as the Source Matter began to continuously shake and flicker. It emitted a pale blue light and finally, under Torifu's gaze, gradually transformed into a sheet of white paper. It was identical to the white paper he had just fed it.
Torifu tried inputting chakra into the Source Matter. Perhaps because the paper's quality was too low, just a small wisp of chakra produced a pile of white paper. Torifu casually picked up a sheet and felt it. He could clearly feel that the quality of this white paper had improved. It had become sharper and tougher. He lit a small flame beneath it, and it took almost a minute of burning before there were any signs of combustion.
"This thing is really good!"
Moreover, that faint chakra hadn't disappeared. Each sheet was infused with Wind Release chakra and had even become more abundant. He hadn't expected such a casual little experiment to actually succeed. Konan's primary chakra nature was wind. If the paper she used already possessed the wind attribute, then her strength would definitely see a significant increase.
"Yahiko, Konan, come over here for a moment, both of you." The two children, who were training, immediately ran over upon hearing Torifu's call. They just didn't know why Torifu had called them.
"Master, is something the matter?" Yahiko was the first to ask.
Torifu smiled and took a fruit from his ring. It was precisely the Bloodline Fruit he had just purchased from the system store. Seeing the bright red fruit, Yahiko felt an inexplicable longing. His intuition told him that if he ate this fruit, he might gain powerful strength.
"Yahiko, since you became a Chunin, Master hasn't given you a reward yet. Consider this fruit your reward; it can awaken a kekkei genkai within you."
Yahiko was completely bewildered upon hearing this. "Huh? Master, I'm not sure I understand what you mean."
Torifu lightly patted Yahiko's head. "What's there not to understand? This is a fruit refined by the Kumotsuru Clan using a secret method. The cost is extremely high, but the benefits are also very clear. Go on and eat it."
A kekkei genkai! That was an incredibly rare talent! Yahiko could be said to desire it immensely; he dreamed of possessing one. But after hearing Master say the cost was very high, he hesitated.
"Master, you should save this for Akihara. I'm doing quite well practicing Water Release; I'm already getting the hang of it." He scratched the back of his head, showing a simple, honest smile.
Torifu shook his head at the sight. "I refined five of these in total, so don't worry and just eat it. You are my disciple, isn't it only natural for a master to give things to his disciple?" Yahiko's nose tingled upon hearing this. Even in a master-disciple relationship, a fruit capable of awakening a kekkei genkai wouldn't just be given away for free. Only Torifu would do such a thing.
"Master, I will definitely train hard! I'll become a Jōnin as soon as possible!"
"Alright, alright, go into the house and eat it now." Torifu said with a smile, waving his hand at him. After Yahiko took the fruit, he bowed repeatedly, then took the fruit and returned to the house.
Konan, who had witnessed everything from the side, was still somewhat dumbfounded. Master made Yahiko awaken a kekkei genkai? That was right, wasn't it? She hadn't misheard, had she?
Seeing Konan's dazed expression, Torifu also called her name. "Why are you just standing there blankly? Do you want a kekkei genkai too?" Konan's heart rate quickened upon hearing this, and her breathing intensified. Was Master going to give her one too?
"Can I… Master."
"It's not that you can't, but Master has something even better for you."
"Huh?" Konan grew even more puzzled. What could be better than a kekkei genkai?
Then, she watched as Torifu took a sheet of white paper from his ring…
"Master… is this the better thing?" Konan could feel that it was just ordinary white paper, seemingly with a faint wisp of wind chakra.
"Try injecting chakra into it." Konan obediently complied. As soon as chakra entered, a large number of white papers surged out of it, fluttering around Konan.
"Master, what—what exactly is this?" Each of these papers was infused with wind-nature chakra, and the paper's quality also seemed much better than what she usually used!
