“I will teach you all that I know, but you must not pass it on to anyone else, especially to some people who are not honest at heart, got it?”
“Don’t worry. We won’t pass on what you teach to others. If I meet someone with good qualifications, I will personally send him here for you to examine!”
North Kai was satisfied with what Ayaka said and had a receptive expression on his face. He then turned his head to look at the sisters, “Your strength is powerful. Even if my North Kai’s Planet has ten times the gravity, it won’t do much for you. So, get your weights back on, increase the weight on your body, and I will train you properly!”
Launch and Lancy nodded respectfully, then manipulated the clothes on their bodies to slowly change the gravity. The body was suddenly under huge weight, coupled with North Kai’s Planet’s ten times special gravity. They felt like their bodies were filled with weight. Every movement was challenging.
They didn’t even walk a few steps, and crystal sweat oozed out of their faces. Their breathing became difficult, with a crackling sound coming from their bones.
Ayaka looked at their difficult walking appearance and was somewhat surprised. It seemed that North Kai’s Planet’s special gravity was really different from the gravity of other planets. Even if they were ten times, the effect was different.
North Kai looked at them, and a faint smile appeared on his face. He then said, “Launch and Lancy, for your first training, grab Bubbles. You have to keep overcoming the limits of your body under difficult conditions so that you can grow faster.”
The two nodded knowingly. Then their bodies awkwardly lunged towards Bubbles, who lightly screamed and dodged to the side in a flash.
Seeing that they had seriously captured the fleeing Bubbles around, North Kai turned to Ayaka, “Ayaka, you are different from them. You are very powerful, and to be honest, I do not have much to teach you anymore.”
Ayaka understood this. With her power level of more than 2.4 million, she already had a certain level of power and basic skills. She had mastered almost everything on Earth. Now, what she lacked was only a variety of techniques, mastering a variety of combat skills, and achieving an increase in power, which was her future path to become a strong person.
Finally, after a moment of silence, North Kai said what she was expecting in her heart, “Since I have nothing to teach you in terms of strength and combat skills, I’ll teach you something a little more special.”
“North Kai, what is it that you are going to teach me?” Ayaka asked, pretending to be confused.
“Ahem, that is some knowledge about the training of various races that I have observed from the Lower Realms through countless years, as well as the result of my lifelong research – Kaio-ken!”
North Kai said proudly, “Twice Kaio-ken can raise twice the power in your body. Twice Kaio-ken means twice the power, and as long as your body can withstand it, you can keep raising your power!”
“But if you exceed your body’s tolerance range, Kaio-ken will be dangerous for your body. You can’t use Kaio-ken continuously, for safety’s sake. It’s best not to make a Kaio-ken that exceeds four times!”
Ayaka’s clear and flawless face emerged with a faint smile, as quiet and elegant as a breeze. She knew that Kaio-ken was not as magical as North Kai thought it was. Because of North Kai’s strength limitations, he did not know that Kaio-ken actually had a ceiling. Like the Saiyan Giant Ape Transformation, the Saiyan Giant Ape Transformation could only reach a maximum of 100,000 power levels. After that, it would not increase the power level.
Kaio-Ken was also the same; only its limit was more lenient, which was 10 million power level. When the power level exceeded 10 million, the role played by Kaio-ken would become negligible.
In the original story, after becoming a Super Saiyan, Son Goku would no longer perform Kaio-ken, mostly using the Spirit Bomb to defeat the opponent. The reason was when Son Goku became a Super Saiyan, the power of Kaio-ken had been negligible.
Ayaka learned Kaio-ken from North Kai. She had some vague ideas in her mind to fuse Kaio-ken with her researched Heavenly Thunder Shock Surprise to develop a perfect punching technique.
“North Kai, teach me Kaio-ken!”
“Mmm, okay. Just get ready to learn my Kaio-ken. After you learn Kaio-ken, you’ll feel that it was worth the trip!” North Kai shouted passionately. His bloated body trembled violently, and then he began to explain to Ayaka the mysteries of using Kaio-ken.
…………
A few days later, after the sisters had successfully captured Bubbles, North Kai brought in a new assistant, the cricket Gregory, to capture. After capturing Gregory, North Kai increased their weight and began to carry out a new round of training.
On the other hand, Ayaka slowly understood the wonders of Kaio-ken. North Kai was worthy of being a martial arts master after a long period of time. There were many wonderful martial arts that Ayaka had never even thought of. After the detailed explanation of Kaio-ken, many incomprehension suddenly opened up.
………..
Looking at the three who were doing their training, North Kai leisurely sat on a rocking chair to the side.
“These three girls are all so outstandingly qualified. The two are two-soul with connection, and the other has almost black hole-like potential. With a little training, they might be able to become a terrifying existence comparable to Frieza. Then it will be possible not to let Frieza do whatever he wants. The evil Frieza Clan might be able to be restrained a bit.”
After several more months of research, Ayaka finally mastered the release of Kaio-ken. She then slowly try to integrate Kaio-ken into her Heavenly Thunder Shock Surprise. Her strength also reached a 2.8 million power level after many days of hard work.
North Kai was surprised and relieved at Ayaka’s rapid growth.
As her strength grew, the thoughts in North Kai’s mind were slowly changing, “It seems that Ayaka’s strength will catch up with Frieza within a matter of time. If she performs the Kaio-ken, she can be temporarily comparable to Frieza! In the future… she can even be more powerful than Frieza!!!”
