I Made a Negative Emotion Collection System (9/10)

Some grassland outside Amegakure, in the Land of Rain. Black Zetsu slowly emerged halfway from the ground with a Pitcher Plant on his head.

In front of him, Obito's robes fluttered in the breeze.

"That Earth Pig became a Genin?"

"Yes. I didn't enter Konoha to investigate, so I wouldn't expose myself. But that's more or less what happened. Sarutobi Hiruzen held a practical combat test. Guess who he defeated?"

Obito's lazy voice came from behind his mask. "Who did he defeat? Kakashi?"

"No, Konoha's Eternal Genin, Maruboshi Kosuke."

"How is that possible?" Obito naturally knew of this legendary ninja. "That old man Kosuke could kill that Earth Pig with just one of his prosthetic legs, couldn't he?"

Black Zetsu layered the word "crafty" into his unique voice. "I thought so too."

"Has he awakened his Sharingan?"

"No, he really hasn't. If he had, I definitely would have collected the relevant information."

"Heh, Maruboshi Kosuke really went easy on him... Maybe Sarutobi Hiruzen was pulling the strings. Our Third Hokage really loves using this method of establishing bonds." As Obito spoke, he adjusted the Akatsuki Organization's Crimson Cloud Black Robe and raised his hand in a handsome pose. "Speaking of bonds, those two civilians and my foolish little brother, could it be that..."

"Your little brother couldn't have helped them graduate early just to find two lackeys, could he? I hear quite a few people want to become his lackeys now. Speaking of which, your little brother has enjoyed everything you never did..."

Obito sneered at that.

"Speaking of which, the three of them really do have a good relationship. In that case, it's time to give him a present. A present for becoming a ninja, and also the coming-of-age ceremony of the Uchiha Clan. He'll definitely like it."

"You're really going to do this?"

"Won't Retsuo be ruined?"

As Black Zetsu spoke, White Zetsu also spoke up. Their voices overlapped, but Obito ignored them.

"Without Rin in this world, nothing matters anymore."

Black Zetsu cackled as he sank into the ground, thinking, There's no way nothing matters. Otherwise, why did you become so anxious and furious when you heard that everything between you and Uchiha Izuna was exactly the same?

But Uchiha Retsuo really is troublesome. We can't deal with him too early...

In the small woods outside Konohagakure.

Uchiha Retsuo squatted on the ground, drawing circles.

In Konoha, Maruboshi Kosuke could be a Genin while Minazuki could be a Jōnin. There was nothing more ridiculous than that.

On the grass nearby, Minazuki was fighting Tenma and Shinji at the same time. Since he was using Konoha Style Steel Fist, the battle was extremely noisy.

Both sides were attacking first, so they could only dodge and did not block at all.

Retsuo had to fairly admit that Minazuki's Taijutsu was stronger than Tenma's and Shinji's. The problem was, you're a Special Jonin...

What makes you special? Your Taijutsu is even worse than that of old man Maruboshi Kosuke?

Soon, Minazuki was suppressed by Tenma and Shinji working together and had no choice but to leap out of the circle and form hand seals!

Snake–Rooster. "Be careful, you two. Wind Release: Gale Palm!"

This technique required simple hand seals and was indeed the first choice when switching from Taijutsu to ninjutsu. But Tenma and Shinji were not polite either, both using Cat Travel Mad God Technique...

A strong gust of wind swept past, instantly blowing the two of them away. Minazuki trembled as he punched at the air. "Go away! Go away!"

Soon, Minazuki escaped the cats' assault by disrupting his own Chakra. His pancake-like face was covered in sweat.

After casually wiping away his sweat, Minazuki sat down on the ground. "Are Genin really this strong nowadays? It would've been great if Shinku hadn't died. He would've been very suitable as your team leader."

Retsuo remained expressionless. "If Third Grandpa had arranged for Shinku to be my Jōnin team leader, our Uchiha Clan would probably have exploded."

"Haha, that's true."

Minazuki scratched his hair awkwardly as he accepted the boxed lunch Shinji handed him. "You two should've run left and right first, then used Genjutsu. That way, my Gale Palm could only attack one of you. It isn't wise to compete in speed with a Jōnin. Wow, Shinji's cooking is really delicious."

"Then please eat more." Shinji smiled sweetly, narrowing her eyes as she acted cute before asking, "Speaking of which, how were you evaluated as a Special Jonin, Teacher Minazuki?"

Hey, hey, is it really okay to ask so directly? Retsuo felt embarrassed. But Minazuki was completely at ease. "Of course there's a reason, and it's a village secret."

It's good that there's a secret. If there's a secret, I don't have to feel awkward anymore! Retsuo lowered his head and wolfed down his food. These past few days, he had been catching cats, finding dogs, cleaning, and continuing to develop his Kekkei Genkai. His days were tiring yet fulfilling, but he was often hungry.

Naturally, the sharp increase in his training efficiency made him hungry.

Previously, his Chakra had been insufficient, so he needed Tenma and Shinji's share as well. Not only did this require their cooperation, he also had to go to Orochimaru's house and make Shinnō serve as a useful tool. The efficiency was extremely low.

Things were different now. Retsuo had made a Negative Emotion Collection System himself.

The Slime only absorbed the purest Dark Chakra, but the Dark Chakra it swallowed always contained some impurities—in other words, positive energy. Sometimes, there was quite a lot of it.

As long as the Light Chakra filtered by the Slime exceeded the Chakra consumed to sustain the second stage of the Yin Release Barrier, he was making a profit.

It sounded as if there wouldn't be much left over.

But it wasn't useless! After conducting several experiments, he discovered that when the barrier was in its first stage, the Slime could not filter anything. In other words, all the Light Chakra was being stored inside the Slime. Once the second stage was activated, it could discharge it all at once—no, filter it with all its might!

Huh? Wasn't this essentially a Yin Seal in another form? When Retsuo discovered this key point, he couldn't help falling into deep thought...

The Yin Seal sealed one's own Chakra, while his sealed Chakra he got for free. If he weren't sure whether this Chakra counted as Yin Release or Yang Release, he could even call it a "Yang Seal."

The only flaw was that he could collect only intense negative emotions. Only Chakra that reached the level of "Darkness" could trigger the Slime's appetite. The kind that increased by +1 and +1 couldn't be collected. The system still wasn't powerful enough.

People like Minazuki had easygoing personalities and laughed everything off. Even when mocked, they could respond calmly. Their mental fortitude was first-rate, leaving Retsuo completely helpless.

After the group finished eating, Retsuo patted his rear and stood up to leave. He caught cats and found dogs in the morning, trained at noon, and spent the afternoon doing what was happiest every day.

Watching Retsuo's departing back, Tenma, Shinji, and Minazuki all fell into deep thought.

Shinji asked, "Should we follow him?"

Minazuki's pancake-like face wrinkled tightly. "Maybe we shouldn't?"

Tenma said, "I'm not afraid of someone attacking me, but based on my many years of experience with Retsuo, he must have a deeper meaning behind this."
