When we returned, it was the middle of the night, so Roshi and Lettu went to sleep in Kame House, while I went out to test out my new ability from the Summoning System, Cross-World Summoning.

"System, tell me, what were the limitations for Cross-World Summoning again? I forgot" I said.

[The limitations are, the summon cannot have a power level less than 100 or exceeding 100000, and it can only be used once a year] The system stated.

"Okay... I somewhat remember the first two... but I don't remember that last part..." I said.

[That is because you weren't informed] The system stated.

"Okay... well then... Cross-World Summoning!" I said, using the ability.

[What world do you want the summon to be from?] The system asked.

This novel is published on a different platform. Support the original author by finding the official source.

"Um... let's stay with the anime theme... the Naruto world" I said.

[Commencing Summoning of Jonin level missing-nin Zabuza Momochi, power level 12000]

"Wait, why is his power level that high?" I asked.

[People from the Naruto world are twice as strong as others, due to the use of Chakra, and ninja are at least 10x stronger than average people. It goes like this, an Average person has a power level of 10, Ninja students have 30, Genin 100, Chuunin 1000, Elite Chuunin 1500, Jounin 10000, Elite Jounin 15000, Kage 200000, Tailed Beast 100000-900000] The system stated.

"Wow... the Kage are ridiculously powerful..." I said, in awe of the Kage's power levels.

[Completed Summoning of Zabuza Momochi] The system stated, as an unconscious injured man covered in blood appeared out of nowhere, in front of me.

"Why is he injured?" I asked.

[Zabuza is near-death because he was summoned during his final fight] The system stated.

"Wait, doesn't that mean that I risk summoning an almost dead person like now?" I asked.

[Yes] The system stated, simply.

"Crap, I have to save him!" I said, as I pulled a senzu bean out of my pocket and made him eat it.

"Master Roshi! I need your help!" I said, as I ran inside, holding the unconscious Zabuza up.

"What do- who's this?" Roshi asked.

"I... saw him washed up on the shore, he looked really hurt so I gave him a senzu bean... but, he needs rest so I'm going to put him on the couch" I said, as I dropped Zabuza onto Roshi's couch.

"Okay... we'll talk to him in the morning, now... get some sleep" Roshi said, as he went back to bed.

"Yes Master Roshi" I said, as I walked to my bed, that was right next to Lettu's and laid down.

"Hey... what was the commotion about?" Lettu asked.

"You'll know in the morning, now get to sleep" I answered, as I fell asleep.
