Arriving at the middle of a desert, far away from civilization and especially Goku, Krillin pulled the seven dragon balls out of his storage and tossed them onto the floor.
Krillin didn't even hesitate for a second lest Goku see the dragon balls in his radar and come rushing over, he waved his hands over the 7 balls and said the activation phrase.
"Arise Shenron!" As he finished saying this the seven dragon balls turned into orbs of golden light and flew into the sky.
Suddenly, the whole sky darkened and the golden lights flew around the sky in a circle, before they merged and everuall turned into a glowing giant green dragon!
"Tell me your wish," A large booming voice emanated out from the mouth of the green dragon, an invisible power different than ki was felt from it.
It was the first time that Krillin had seen such a huge dragon. The deafening sound made Krillin freeze in place, it took him a few seconds to react.
"I...I wish for the power to heal all ailments, whether they be broken bones, heart viruses, infection or even brain eating amoeba!" Krillin yelled out to the giant dragon.
"Your wish.... Has been granted" suddenly a beam of green light flew out of the dragon and into Krillins brain, knowledge of a healing magic began pouring into Krillins brain.
With his wish completed Shenron immediately split apart into 7 orbs of light and flew off to different locations on the earth, Krillins compass was still work and knew immediately where the closest one had landed.
With the dragon completely gone, Krillin followed along with the knowledge Shenron had granted him when suddenly a green energy collected around Krillins right hand.
'Good! With this i don't have to worry about any timeline BS!'
Once Krillin realize that their was some other force affecting this worlds events he came to a horrifying idea, what if this was the orignal timeline and not the tv show timeline!
Later in the show Goku contracts a lethal heart virus that would kill him, it was only because trunks from a future timeline goes back to give Goku medicine that he survive.
The thing is that the Goku in the orignal/future timeline didn't have a future trunks to help them, so Goku just died from the virus and the androids destroyed the world!
The idea that Krillin was in the timeline where Goku dies was terrifying, the whole universe was at risk without the loveable fight maniac to protect it.
'With this I ensured Goku's and humanity's future whilst gaining a powerful healing magic, sorry Bora but your revival isn't worth guaranteeing the survival of the planet and universe!'
Krillin quickly got on his nimbus and flew away from the spot, not wanting to be caught if Goku doubled back to find out who made the wish.
Krillin knew that stronger and stronger Androids would keep coming, the Anomaly that is Dr Gero has somehow increase the strength of his Androids drastically.
He couldn't let his powerlevel stagnate again like he did with Annin, at the end of the day physically strength and Ki played an equally big part as control and technique.
There are even some beings like Buu, Frieza and Broly who have little to no fighting technique or control and relied entirely on their physical strength and overwhelming ki to crush their opponent. Krillin needed to raise his power level as well as technique and thankfully he just gained the Paradise Herbs!
On his nimbus Krillin rode back to West City, there he made a solid illusions of Zenni to buy enough food, water and clothing needed for a couple years. Krillin found it much harder to create illusions of actual money like zenni than gold because of their serial numbers but he managed to get buy.
He bought all the material he needed to train and even stopped by the antique shop he robbed the Bansho Fan from and gave them enough money that even their great grandkids wouldnt have to work.
With all of his debts and necessities taken care of, Krillin went back to Korins tower.
Arriving at the tower again, the sweaty Korin watched Krillin hop off the nimbus and began walking over to the nervous cat.
"So much action for one day, first it was an assassin with a powerlevel that rivals Kami then It was a cyborg that's powerlevel surpassed all known creatures in history multiple times over. Yet you managed to defeat him!" Korin said as he watched Krillin conjured up a syring with his solid illusions.
"Your right, we came so close to dying and this entire world wouldve been doom... That's why I'm gonna need a favour's from you Korin, I need some of your blood to become powerful enough to stop the incoming dangers!" Korin realized why Krillin had a syring now and only continued to sweat further.
"I don't know about that Krillin...I know there's all sorts black magic spells that can curse or bind someone with blood. I don't fee-" infront of korins eyes, Krillin suddenly dissappear via timestamp and a hand was now hanging on his shoulders causing the cats eyes to widen in shock.
If krillin could've, he would've already gotten the blood via timestop but even the needle couldn't puncture skin during time stop so had to do it the normal way.
"Master Korin not to offend or be disrespectful, if I wanted to you'd already be dead. I'm already faster than you can perceive and you stand no chance at defending against me. Why would I need to go through some convoluted blood curse, I need your blood to help save our planet from destruction so I plead with you, please let me collect some of your blood." Krillin hyped up his strength with time stop to help his message.
Korin opened his mouth to refuse, his mind trying to come up with a valid reason to refuse when he just let out a sigh as he looked at Krillin's clear honest eyes.
"Fine...." Lifting up his arm, Korin hesitantly relented and gave Krillin his blood.
"Thank you master Korin, ill put your blood to good use and grow much stronger because of it. I'll be going up to Kami's lookout and won't come down until I forge myself into a force of nature!"
Opening the window at the tallest part of the tower, Krillin simply floated out leaving Korin to watch the bald monk begin ascend into the air and towards the god of earth!
