Quantum Mechanics

"Do you have any Summoned Beast?" Obito looked at Honoka.

Honoka hesitated for a while, but finally nodded.

In addition to a large amount of money, the reward for this mission was also a bird Summoned Beast. This was one of the main reasons why she accepted the mission.

Although she knew that it was definitely not a good thing to do as the masked man asked, she had no other choice in this situation.

"Summoning Technique!"

Honoka quickly made a series of hand seals, and then fiercely slapped the ground to summon a big bird.

Before the big bird could understand what was going on, Obito kicked it toward of the Ultimate Summoned Beast.

Seeing that there was food in front of it, the Ultimate Summoned Beast did not just sit idly. Several thick tentacles tied up the big bird and stuffed it into the huge mouth full of fangs in its abdomen.

After a while, two bulging meat buns appeared on the originally smooth back of the Ultimate Summoned Beast. Then, a pair of gray wings stretched out from the meat bag.

Perhaps because it had just grown out, its wings were not big and had not yet broken through the Ultimate Summoned Beast's back. It looked a little funny.

"Interesting." Obito looked at the Ultimate Summoned Beast that had grown wings after eating the bird. He nodded in satisfaction.

Although it was still weak now, if it had the ability to devour other Summoned Beasts, it could be considered a potential stock. Unfortunately, it was too ugly. Otherwise, Obito might have used it as a Summoned Beast.

The Ultimate Summoned Beast that had grown wings was very excited. It waved its little wings hard. With the support of Chakra, although the wings were very small, it could actually make him fly.

With a new ability, the Ultimate Summoned Beast could not help but look at Obito with greedy eyes again.

This food had just hit it so painfully that it wanted to take revenge.

It could not beat it just now, but it should be able to beat him now that it had become stronger.

"Roar!" The Ultimate Summoned Beast once again used the sound wave illusion that it had obtained from the dog-type Summoned Beast. It wanted to use this to leave Obito in daze and then launch an attack.

However, the Ultimate Summoned Beast was still too naive. Just swallowing an ordinary bird type Summoned Beast did not bring much improvement to him. It only had the ability to fight in the air.

"Monsters are monsters, no brains." Obito felt the weak mental attack, and the corner of his mouth revealed a mocking expression. Then, he quickly formed hand seal, and a black tree flew out from the ground.

The Ultimate Summoned Beast had just learned how to fly. It was not fast and could not fly steadily. It could not dodge Obito's attack and was directly pierced by the black tree. 

"Woo ---" The Ultimate Summoned Beast let out a sad cry and fell to the ground.

Then, Obito used his Chakra and kicked the Ultimate Summoned Beast into the wall of the research base.

"Remember this lesson. Do not try to challenge me." Obito said coldly.

He knew that the Ultimate Summoned Beast had intelligence and could roughly understand what he meant. Otherwise, he would not have been so obedient after being beaten up just now.

It simply thought it had the chance after devouring a Summoned Beast.

However, the gap between them was not something that could be compensated by swallowing one or two Summoned Beasts.

"Roar!" The Ultimate Summoned Beast used its tentacles to pull itself out of the wall and nodded rather obediently.

It was unknown if it was because of the effects of the Dog Gene in his body, but it even stuck out its forked tongue and waved its tentacles, as if trying to get on Obito's good side.

However, even Zetsu found the Ultimate Summoned Beast ugly and ridiculed it.

Even he did not like it, let alone Obito. He almost couldn't help but dish out another Great Fireball Technique on the Ultimate Summoned Beast's face.

Did he not know how he looked?

"Well, can I go now? I can give you all the money I have. Although it is not a lot, 800,000 Ryo should be enough, right...?" Honoka said weakly.

Obito looked at Honoka indifferently. He thought it was pretty good. Finding the pure-blooded Uzumaki sure was hard.

Obito quickly used a Genjutsu on Honoka.

Honoka's eyes instantly became empty, and he slowly walked behind Obito.

...

"Hu hu!"

Nagasawa, who was sitting in his room, let out a long breath and adjusted his state. He was ready to enter the Hell Difficulty Challenge Mission.

No matter how much you think about it, it would be better to practice Sage Mode in the Challenge Mission, and then fought those so-called Six Paths-level enemies.

Nagasawa entered the system, chose Tobirama Senju's template, and clicked on the challenge mission.

[ - Tobirama Senju's challenge: Defeat Obito Uchiha, Madara Uchiha, and Kaguya Otsutsuki as the main fighting force. Reward: 10% fusion rate. ]

[Do you want to attempt the challenge?]

"Yes."

[Due to the difficulty of the challenge, after entering, you will not directly replace the template character. ]

Nagasawa thought about it, probably because the system also felt that it was a bit too much to let him fight three Six Paths-level big bosses at once, so it did not replace Tobirama and create another character instead.

From this perspective, it seemed that the system was also quite good... That was weird.

Although Tobirama was very strong, it depended on who his opponent was. With Six Paths Obito, Six Paths Madara, and Kaguya Otsutsuki as opponents, Tobirama could only play the role of a support support.

[Because you're not replacing the template, you can choose whether to use your real face or not. Do you want to use it? ]

"No." Nagasawa directly refused.

Of course, he had to use the Second Hokage's face.

With his own face, if the people in that timeline did not know him, how could they happily clear the ordeal together?

As for how to explain that there were two Second Hokage, it would be easy to solve it.

When faced with problems, you can always answer it with "quantum mechanics or parallel universe."

Just tell them that he was a Tobirama Senju from a parallel universe.

He had 90% fusion rate on Tobirama's template. He knew the Ninjutsu that Tobirama could use. If someone doubted him, he could immediately use Tobirama's classic Water Release and Flying Thunder God Technique.

With such a combination, Tobirama himself would have to seriously think whether parallel world did exist or not.

After all, he had the exact same appearance as him, and he also had the exact same Ninjutsu. as him!

Of course, Tobirama was also a master of Forbidden Techniques. He had a big brain hole, so he might be able to guess that Nagasawa was an existence like his clone.

[ - Entering Challenge... ]

Nagasawa instantly felt his vision go black and he lost consciousness.
