Old Kai

With loud explosions, energy waves detonated in the sky.

"Whoosh..."

Mechickabura flickered and instantly appeared in front of Son Goten, thrusting his staff forward to attack.

Son Goten flickered and appeared behind Mechickabura.

Mechickabura was startled and quickly turned around, seeing a fist flying towards his face.

Mechickabura's body shot backward like a ray.

Seizing the opportunity, Son Goten clasped his hands behind his back.

"Kame~hame~ha~Wave!"

A deep blue energy wave gathered in Son Goten's hands and shot towards Mechickabura.

Mechickabura was greatly alarmed, but it was too late to dodge.

Bang!!

With a violent sound, the Kamehameha hit Mechickabura, pushing his body backward.

Immediately after, with an immense explosion, the Kamehameha detonated in the sky.

A massive storm appeared, sweeping outwards in all directions.

Son Goten gathered his ki and formed a semi-transparent shield to block the raging wind.

After a while, when the explosion stopped, a system voice suddenly sounded in Son Goten's ear.

"Ding! Congratulations to the host for defeating Mechickabura. You have learned Dark Body, Dark Ki Blast... and Darkness Devour."

Upon hearing this, Son Goten immediately looked forward.

As the thick smoke gradually dissipated, Mechickabura's body slowly became visible.

Mechickabura panted heavily, his clothes torn in many places, looking extremely disheveled.

"Immortality?"

Mechickabura had devoured much of history, so his body likely possessed "Immortality."

Mechickabura did not reply but raised his staff and fired an energy wave at Son Goten.

Son Goten easily dodged to the side.

At that very moment, Time Patrol Son Goku arrived with Kaiin and the others.

Time Patrol Son Goku: "Goten!"

Son Goten nodded and reverted to his base form.

"Since you're here, I'll leave this guy to you!"

"Wait!"

Kaiin shouted at Son Goten with extreme seriousness.

"What is it?"

"Who are you, and how can you travel through time and space?"

"I am Son Goten. As for why I can travel through time and space, I cannot tell you. We shall meet again!"

After speaking, Son Goten immediately opened a time-space gate and left the Dark Demon Realm.

"Supreme Kai, should we pursue him?" Time Patrol Gohan asked.

"No, let's deal with this guy first!"

Time Patrol Son Goku and the others immediately looked at Mechickabura.

"Supreme Kai!"

Mechickabura gritted his teeth upon hearing this.

Then, the Time Patrol engaged Mechickabura in a fierce battle.

Finally, Mechickabura was permanently sealed by the Time Patrol using the Key Sword.

Main Timeline.

Son Goten returned to the main timeline. Since there was nothing to do at home, he borrowed Gohan's Kaioshin Sword.

At this moment, he was wielding the Kaioshin Sword in the mountains behind his house.

After swinging the Kaioshin Sword for a while, Son Goten transformed into Super Saiyan 4 and firmly gripped the blade of the Kaioshin Sword with his right hand, bending it outwards.

"Crack..."

With the sound of a long sword shattering, the Kaioshin Sword was broken in half.

Son Goten looked around and found nothing.

After a while, an old man in a Supreme Kai uniform suddenly appeared behind Son Goten.

This person was Old Kai.

Son Goten turned around as if sensing something and saw the hunched-over Old Kai.

"Did you save me?"

Old Kai asked.

"Mhm!"

Son Goten nodded.

"Then what's your name?"

"My name is Son Goten!"

"Son Goten!"

"Then how did you know I was trapped in the sword?"

"Lord Champa told me!"

"Lo... Lord Champa? Are you talking about the God of Destruction from Universe 6?"

"That's right!"

"Then how did you get the Kaioshin Sword?"

After hearing this, Son Goten immediately told Old Kai about Majin Buu.

When Son Goten finished speaking, Old Kai looked at him calmly and said.

"I see, so it was actually your brother who pulled out the Kaioshin Sword?"

"Mhm!"

Son Goten nodded.

"This is troublesome, because my original plan was to repay the person who pulled out the Kaioshin Sword!"

"Repay?"

"Yes, I'm a Supreme Kai, after all. I know about repaying kindness!"

"Are you very strong?"

"Of course!"

"Then how about we have a fight?"

"Cough cough!"

Old Kai coughed.

"The strength I'm talking about is different from what you understand as strength!"

"Different?"

"The strength I'm talking about refers to my abilities. I can raise a person's power to beyond their limits. Do you understand, beyond their limits?"

"Oh, then can you fight me?"

"..."

Old Kai was speechless.

"I already told you, I'm not strong in fighting. My abilities are what's strong!"

"It's okay, Old Kai, I won't use my full power!"

"..."

Old Kai was speechless again.

Was this a matter of using full power or not?

"Goten, look, I'm already an old man. Do you think I can still fight you?"

"Why not? Grandpa Master Roshi can still fight Dad!"

"Who is Master Roshi?"

"My dad's master!"

Old Kai looked at the "innocent" Son Goten and couldn't do anything about him, so he could only agree and say.

"Alright, alright, but I'm just an old bone now. You can't be too rough when you attack!"

"Okay!"

Son Goten smiled and nodded.

Looking at Son Goten's smiling face, Old Kai had already made up his mind to immediately admit defeat once their fight began.

"Then Goten, go ahead and attack!"

"Okay!"

As soon as the words fell, Son Goten punched the Old Kai hard in the face.

The Old Kai let out a loud scream and was sent flying backward like a ray, crashing into the large mountain behind him.

"Ding! Congratulations to the host for defeating the Old Kai, obtaining Clairvoyance (able to see insect battles on Earth from the Kaioshin Planet), learning Godly Instant Transmission... An additional reward of a crystal ball (can use magic to see everything in Universe 7)."

"That hurt so much!"

Just then, the Old Kai clutched his head and shouted.

"Son Goten, I told you to go easy on him, and you still hit him so hard!"

Seeing this, Son Goten quickly ran over and offered him a Senzu Bean.

"I'm sorry, Lord Old Kai, this is a Senzu Bean. As long as you eat it, your injuries will heal!"

"Senzu Bean?"

"Yeah!"

Son Goten nodded.
