In The Dragon Ball Universe With The Summoning System

I looked at Master Roshi, shocked. We were going to meet, either Ox King. Chichi's father, or the original Son Gohan, adoptive grandfather of Goku.

"Um... who are we going to meet first?" I asked.

"Hmm... I want to see what Ox King's up to, so we'll meet up with him first. Maybe he can show you a few moves of his" Roshi said with a small smile.

"Okay, let's go!" I said, as I tried to fly to the Ox King's house, but I forgot two important things. I didn't know where it was, and I forgot to cancel the summoning of the Saibaman, who was still under orders to attack Lettu...

"Yeah! Let's g-" Lettu said, before getting punched in the face by The Saibaman.

"Oh crap! Right! Sorry! Cancel Summon!" I shouted. And the summoned Saibaman simply, disappeared.

"What in the world was that Tomant?" Roshi asked, obviously shocked.

"I... um, have a special ability that allows me to contract beings and summon them... can you keep this a secret?" I admitted almost instantly to Master Roshi, mostly because I know that I can trust him to keep this a secret.

"Of course, my dear disciple... do you have access to any other... summons?" Roshi asked, his curiosity peaked.

"No, just that one... I should really consider naming him too..." I said.

"So, how are we going to get to the Ox King?" I asked, slightly confused.

"By using the flying nimbus" Roshi said, as a yellow cloud appeared right next to him.

"Now, you must know, the nimbus only allows those of a pure heart onto it, like so," Roshi said, as he tried to hop onto the nimbus, but fell straight through.

"Um..." I just looked at him, awkwardly.

"Pfft! Hahaha!" Meanwhile, Lettu was rolling on the floor laughing "Looks like you're not so pure of heart, are you old man!?"

"..." Roshi just looked at Lettu in shock. 'This is the first time I've seen him so... happy' he thought, as he slowly got up and whacked Lettu on the head. "Don't laugh at your master, brat!"

"Argh! That hurt! You're going to pay for that you old bastard!" Lettu shouted as he readied a ball of ki.

"Damn it Lettu, hopefully, you'll get a hold of yourself in the morning" I shouted, as I fired a ki blast at the back of the head, knocking him out.

"Okay... I think I have an idea of what to do... get your plane and we'll go on that!" I said to Roshi, slightly annoyed.

"Alright... damn brats are going to be the death of me..." Roshi muttered in annoyance, as he grabbed the capsule out of his pocket. "You do know, that was actually my backup plan, right?" Roshi asked.

"..." I just ignored him, as I carried Lettu to the passenger's seat of the plane. "Alright, you go on ahead, I'll catch up!" I said, with a small smile.

"Alright..." Roshi said, as he flew off.

"Now... I do think it's time to see what my power level is..." I said with a small smile, as I walked into Kame House and looked at myself in a mirror.

[11000]

"Damn... I've already reached 10000!" I said with a grin.

[Congratulations host, you have the chance to unlock one of three functions of the Summoning System] The system said.

"What functions?" I asked.

[Mutation, Cross-World Summoning and Self-Fusion] The system stated.

"Okay... can you give me a more... in-depth analysis of the functions?" I asked.

[Mutation: Mutates a summon of your choice over 10000 years. Cross-World Summoning: Allows the host to choose a world to summon beings from, with a few limitations. Self-Fusion: Allows the host to temporarily fuse with a summon of their choice] The system stated.

"Okay... can you tell me the limitations of Cross-World Summoning?" I asked.

[The limitations are, the user cannot summon anyone with over 10 times their power level, and cannot summon anyone with a power level of less than 100]

"Okay... I choose Cross-World Summoning... now, I have to start following Master Roshi... right after I grab that Dragon Ball..." I said, as I quickly grabbed the three-star Dragon Ball and flew off.

"I can't wait to meet the Ox King!" I said with an excited grin.

__________________________________________________

Meanwhile, the Ox King was sleeping in a small house, completely unaware of his new arrivals.

His daughter Chi Chi, was playing by herself, alone, ever since her mother died of an illness and their castle was lit ablaze, there wasn't anything to do, so she was incredibly bored most of the time.

That was, until she met an old man and two little boys.

"Hello, there little girl... can you give me directions to The Ox King's Castle?" The old man asked.

"Why should I tell you?" Chi Chi asked.

"Because, my disciple Ox King lives up there, and I want to introduce him to his martial juniors" The old man said with a smile.

"Ox King? Do you mean my papa?" Chi Chi asked, confused.

"Papa? You're Ox King's daughter?" The old man asked, shocked.

"Yeah!" Chi Chi said with a grin.

"Okay... can you tell him that Martial arts Master of the turtle school, Muten Roshi is here to see him?" Roshi asked.

"Okay... PAPA!" Chi Chi shouted loudly.

"What, sweetie?" Ox King asked loudly.

"There's an old man named Roshi here for you!" She said.

"Tell hi- Roshi? Muten Roshi!?" Ox King asked.

"Yeah!" Chi Chi shouted, and suddenly you could hear loud clanging and the sound of glasses smashing.

"Give me just a second!" Ox King shouted.

"He said he'll be here in a second" Chi Chi said.

"...We heard" Roshi said, slightly awkwardly.

Almost seconds after Roshi said that, a large man wearing armour appeared, this was the Ox King.

"Hello Roshi" Ox King said, with a big smile.

"Ox King, it's good to see you after so many years," Roshi said, with a smile.

"You too Roshi... hmm, who are these younglings?" Ox King asked out of curiosity.

"These two are the latest Turtle School disciples, I wanted them to meet their seniors, before their official training, maybe they could learn a few moves off of you and Gohan" Roshi said, his smile turning into a grin.

"Of course, I would be completely willing to help whip these younglings into shape" Ox King said, wiht a menacing grin.

"Actually, I've done that for you. They spent a year as my personal disciples before I deemed them worty of the turtle school" Roshi said.

"Ah, good... how strong are they?" Ox King asked.

"Strong enough to kill me" Roshi smiled.

"Really!? These brats could kill the martial arts god Muten Roshi!?" Ox King asked, completely shocked.

"Yes, in terms of raw power, they could easily kill me. But, in terms of techniques, I vastly outclass them" Roshi said with a proud smirk.

"Yeah right old man, we can easily beat you if we want to!" Lettu said with a cocky grin.

"Shut up Lettu, or I'll take out my Saibaman" I said, threateningly.

"...Fine!" Lettu harrumphed.

"So, what are these kids' names?" Ox King asked.

"The cocky one's Lettu and the other's Tomant" Roshi said.

"Okay, now... what's a Saibaman?" Ox King asked, slightly confused.

"Oh, do you want to see him? I've yet to name him! But, he's really strong!" I said with glee.

"Okay..." Ox King said, slightly cautious.

"Summon!" I shouted, and the Saibaman popped into existence.

"Gah! What is that!?" Ox King asked, shocked.

"That's Tomant's Saibaman... a pet... so to say" Roshi said.

"O-okay... so, do you children want to learn some of my techniques? I'll just tell you now, over half of them involve the use of an axe... so I'll show you the other two" Ox King said, as he walked outside.

Lettu and I simply followed him, Chi Chi and Roshi were also watching.

"Okay, so this one I call, Gigantic Rock Throw... you simply grab a large rock, like this" Ox King said, as he grabbed a large rock "And throw it... like this! Hya!" he then threw the large rock towards the distant castle.

"So... you just... threw a large rock?" Lettu asked, unimpressed.

"Lettu, imagine how much strength it must have taken for him to have thrown it that far!" I said, in Ox Kings defence.

"Okay... now, this one's called... Charging Mad Bull!" Ox King said, as he charged directly into a tree, knocking it down. "So, how was that?" Ox King asked.

"You... just ran into a tree..." Lettu said, still unimpressed.

"Lettu, do you know how much strength and speed it would take to knock down a tree with just your body!?" I shouted, still in Ox King's defence.

"No... it's okay... you don't have to defend my unimaginative moves... I just smash or throw, not much else... not suited for ya younglings..." Ox King said, as he slumped down.

"Well, they may not be good for us, but... why don't you try teaching your daughter?" I suggested.

Ox King just looked at me, then looked at his daughter. And his face visibly brightened.

"Yes! You're right! I can train my daughter into a might martial artist!" Ox King said with a grin.

"So, Ox King... do you want me to help you out with your fire problem?" Roshi asked.

"Um... please?" Ox King asked.

"Okay... Kame...Hame...HA!!!!" Roshi shouted, as he shot a Kamehameha directly at the Ox King's castle, destroying it in the process. "Uh... sorry..." Roshi said, apologetically.

"Nah... it's fine, you got rid of the fire... now, we can rebuild..." Ox King said with a smile.

"Well then... we have to go" Roshi said, as he hopped back into his plane. "Off to Gohan's!" Roshi shouted.
