"Now you all know the power of my [Kaio-ken], don't you? Whoa, whoa, whoa..."
Kai, laughing heartily, approached along with Bubbles and Gregory.
Although he had recognized Yuujin and Goku's potential, even Kai hadn't expected them to reach this level, filling him with great astonishment.
"Indeed, it's truly worthy of being the martial art created by Lord Kai. We owe it to your guidance."
"Lord Kai, we've already disturbed you for a whole year. After this, I plan to bid farewell with Goku and the others," Yuujin said. Kai didn't show any surprise at his words.
"Go ahead, go ahead. If you don't leave soon, my planet will eventually be torn apart by you. Besides, there's nothing more I can teach you."
Seeing Kai's expression of disdain, Yuujin couldn't help but blush.
Due to frequent sparring sessions, Kai's Planet often ended up in ruins because of Yuujin and Goku's training, almost getting destroyed multiple times. Thinking back, Yuujin couldn't help but feel guilty.
But it was time to end things here. They had been training for a year, and with the Kaio-ken and Spirit Bomb techniques already mastered, there was no need to stay any longer.
Besides, Bulma and Tights were still waiting on Earth. His longing for the girls made Yuujin eager to fly back immediately.
Even so, there was no need to rush.
After all, Kai had painstakingly guided them for an entire year, even teaching them his two unique techniques. It wouldn't be polite to leave abruptly after learning everything.
Yuujin and Goku returned to their quarters to freshen up and change clothes. Yuujin then asked Princess Snake and her attendants to prepare a lavish feast to thank Kai for his year-long guidance, marking a perfect conclusion to their training.
Everyone gathered, eating and drinking heartily. After the feast, Yuujin, Goku, and the girls were ready to leave.
Having packed their belongings, Kai, Bubbles, and Gregory were there to see them off on Kai's Planet.
"Yuujin, Goku, Chichi, it's impressive that you completed the training here and mastered my [Kaio-ken]. You are all outstanding martial artists," Kai said.
"But I hope you remember not to let power cloud your true selves, and never use the martial arts I taught you for harmful purposes."
"Yes, Lord Kai," Yuujin, Goku, and Chichi replied earnestly as Kai adopted a rare serious tone.
Nodding, Kai continued, "Besides the [Kaio-ken], you two have also learned the [Spirit Bomb]. However, I hope you won't teach the [Spirit Bomb] to anyone else."
"The [Spirit Bomb] is even more dangerous than the [Kaio-ken]. If it falls into the wrong hands, it could bring great catastrophe to the universe. Do you understand?"
During their year on Kaio's Planet, Yuujin, Goku, and Chichi all learned the [Kaio-ken], but only Yuujin and Goku managed to master the [Spirit Bomb].
Although Chichi's talent was impressive, as a human from Earth, she couldn't quite match the pure Saiyans, Yuujin and Goku. Learning the [Kaio-ken] had already pushed her to the limit, and mastering the [Spirit Bomb] proved too challenging.
"Don't worry, Lord Kai, we won't teach the [Spirit Bomb] to anyone else," Yuujin assured. He understood that such a secret technique should remain exclusive, so Kai's reminder wasn't even necessary.
Satisfied, Kai nodded and said no more.
"Lord Kai, thank you for your guidance over the past year. We shall take our leave now."
"Goodbye, Kai, Bubbles, Gregory!"
"Chichi, Goku, come visit again sometime."
After bidding each other farewell, Princess Snake transformed into a small snake and wrapped around Yuujin's waist. Then, Yuujin, Goku, and Chichi erupted in energy, shooting into the sky like three bolts of lightning...
On Earth, West City—
Night had fallen, and the city lights illuminated the dark land.
In a corner of West City stood a tall building of several stories.
Although it appeared to be an ordinary building, it wasn't. It was one of the many secret research bases of the Dragon Ball Corporation in West City.
Back when Yuujin entrusted Bulma with advanced alien technology beyond Earth's level, it wasn't ready for immediate use. It had to undergo extensive calculations and testing to develop products suitable for humans on Earth.
To achieve this, Bulma had established numerous research bases, assembling a large number of scientists and technicians to analyze the alien technology and develop advanced products, earning substantial profits for the Dragon Ball Corporation.
Since it was already after hours, the staff had left the building, with only security personnel patrolling to ensure the facility's safety.
However, tonight, an unexpected visitor arrived.
It was a woman with beautiful blonde hair and a voluptuous figure, silently landing on the rooftop using a glider like a bat.
The research building was tightly secured, with the entire structure completely enclosed. Yet, the woman skillfully opened a window and slipped inside.
Numerous surveillance cameras and laser defenses lined the corridors, ready to trigger the alarms within seconds of detecting an intruder.
But the woman moved with disdain for these security measures, effortlessly avoiding the cameras and lasers like an agile panther. She easily made her way into the central laboratory.
Inserting a pre-prepared USB device into the computer, she used a trojan program to breach the system's defenses and quickly began downloading the research data.
The download took over half an hour due to the large amount of data. Once the transfer was complete, she breathed a sigh of relief.
As expected, everything went smoothly.
Although she had no interest in the research data, and didn't even know what it was, it didn't matter. As long as someone needed it, that was enough.
Once she delivered the USB to her employer, she would easily earn a $1,000,000 reward.
A smile appeared on her lips as she prepared to leave and enjoy a relaxing bath at home, but suddenly, a cold voice spoke behind her:
"Put it down, Hao Siqi!"
