Steel Temple - The Prosperity of New Vegeta City

Kashu led the group toward a mountainous region hundreds of kilometers west of West City. Among the peaks stood a peculiar mountain shaped like a giant fist, stretching from the ground toward the sky with a flattened summit that formed a platform. A metallic structure stood upon it; from a distance, it looked like a castle, but up close, it was clearly a base that fused Earth technology with extraterrestrial science. "This is..." Bulma's eyes widened. "This is Dr. Gero's Northern Laboratory!" "That's right," Kashu said, landing on the edge of the platform. "Dr. Gero had over a dozen laboratories on Earth, and this is the largest one. He conducted his research here after Android 16 was activated." Bulma walked up to the metal building, carefully observing the structure of the exterior walls. "These materials are completely different from Capsule Corporation's technology... they're closer to the tech we found in the alien ruins." "That's because Dr. Gero found these technologies in those alien ruins," Kashu explained. "The ruins were on the far side of the moon, left behind by ancient extraterrestrials. Dr. Gero spent ten years excavating them and brought back a massive amount of technology and samples." He walked to the main gate and pressed his palm against the identification panel. The panel glowed blue, scanned his palm print, and the gate slowly slid open. "You can still open the door?" Krillin asked in surprise. "My father was Dr. Gero's assistant, and he had high-level clearance. My genes contain his DNA, so the system recognized me." Kashu walked inside, and the sight within left everyone stunned.

The hall was as spacious as a football field, with a ceiling dozens of meters high hung with massive holographic projectors. The walls were embedded with countless screens, flickering with various data and images. The floor was covered in all sorts of instruments, some still running, others long dormant. In the center of the hall stood a massive circular device over twenty meters in diameter, composed of countless metal rings that rotated slowly. "What is this?" Gohan asked, approaching it curiously. "An Energy Aggregator," Kashu said. "It can extract energy from a planet's core and compress it into a usable form. I used this device to modify Android 17, Android 18, and Android 16." Bulma's eyes lit up. "Incredible... what is the energy conversion efficiency of this device?" "Nearly one hundred percent," Kashu said. "The technology of that alien civilization is far beyond our imagination." He led the group through the hall to a room. Inside were dozens of incubation tanks; some were empty, while others held strange things—severed mechanical limbs, beating artificial hearts, and eerie biological tissues. "This is where Dr. Gero created the Androids," Kashu said. "Every tank once held a life. Some were volunteers, and some were... forced." Android 18 looked at the tanks, her body trembling slightly. She recalled the scenes of being strapped to an experimental table, injected with various serums, and having an energy reactor implanted in her. Those memories, though suppressed, had never truly vanished. Kashu walked to her side and gently patted her shoulder. "It's over," he said softly. "All of that is in the past." Android 18 looked up at Kashu's face. His expression was gentle—no pity, no sympathy, only understanding. A true understanding of her pain.

She nodded, took a deep breath, and pushed those dark memories back into the depths of her heart.

Over the next few days, everyone threw themselves into training. Kashu taught Goku and Vegeta how to compress their ki. He had them maintain their base state, then slowly ascend to Super Saiyan, gradually compressing the energy to prevent it from leaking out. Goku learned quickly. By the third day, he had mastered the basic technique, compressing his Super Saiyan ki by half, which actually doubled his power. His body no longer radiated a golden aura, making him look like an ordinary person, yet a casual punch could shatter a boulder. Vegeta learned more slowly, but his tenacity was immense. He trained sixteen hours a day, eating and sleeping in the training room. Kashu designed a specialized program for him, forcing him to perform compression training under one hundred times gravity. Gohan followed Kashu to learn a different technique—the awakening of the Mystic Form. Kashu told him that the Super Saiyan transformation was a shortcut that used anger to stimulate potential, but it had a limit. True power did not lie in transformation, but in fully integrating one's potential into the base form. "You must forget about being a Super Saiyan," Kashu told Gohan. "Don't think about transforming, don't think about anger. You just need to... be yourself. Be a pure person, unaffected by any emotions." Gohan found it hard to understand at first. He was used to using anger to trigger his power, and being told to abandon it felt like losing his direction. But Kashu taught him meditation, how to feel the flow of every thread of energy within his body, and how to guide that energy from his dantian throughout his entire being. It was a method close to ancient martial arts, but far more refined than the Turtle School's training.

On the seventh day, Gohan suddenly succeeded. He was sitting in the center of the training room meditating when his body suddenly emitted a soft glow. It wasn't the golden aura of a Super Saiyan, but a silver-white halo, like moonlight shimmering on a lake. His hair didn't change color, remaining black; his eyes didn't change, remaining deep brown. But his ki underwent a qualitative change, shifting from a violent flood into a deep, vast ocean. The Mystic Form. Kashu stood outside the training room, watching the change in Gohan, and nodded with satisfaction. "Success," he said. "Son Gohan, you are now a warrior on the level of a Super Saiyan 3. Yet, you look like an ordinary person." Gohan opened his eyes, feeling the power surging within him. He clenched his fist lightly, and the surrounding air vibrated. "Is this... the Mystic Form?" "To be precise, it is the initial stage of the Mystic Form," Kashu said. "You still need to consolidate it further. Once you fully master this state, your power will increase even more." Gohan stood up, walked to Kashu, and bowed deeply. "Thank you, Mr. Kashu." "Just call me Kashu," Kashu smiled slightly. "We are family now." After the Cell Games, New Vegeta City entered an unprecedented era of peace. The Saiyan population surpassed one thousand, and the city underwent its fourth expansion, doubling in size. New Vegeta City now had its own schools, hospitals, shopping centers, parks, and even playgrounds. Saiyans and Earthlings lived in harmony, their cultures blending to form a unique Saiyan-Earth hybrid civilization. The relationship between Bulma and Vegeta had undergone a subtle change. Although Vegeta wouldn't admit it, he began to take Bulma seriously after Trunks's prophecy. The two began dating (though Vegeta called it "training"), and Bulma was overjoyed. Krillin and Android 18 (Lazuli) lived a very happy married life. 18 was pregnant, and Krillin was so excited he spent all day grinning like a fool. Tien Shinhan and Chiaotzu became the "guardian deities" of New Vegeta City. Although Tien Shinhan had inherited the throne of the Three-Eyed Clan, he chose to remain on Earth to protect the land that had given him a new life. The relationship between Piccolo and Gohan grew even closer. Piccolo taught Gohan combat techniques, and Gohan taught Piccolo how to read and write. They were teacher and student, friend and friend, father and son.

Kashu's three children—Kariel, Kabrun, and Kassis—attended school in New Vegeta City. Kariel inherited her father's talent, learning to transform into a Super Saiyan at age nine; Kabrun inherited her mother's intelligence, building simple robots by age eight; Kassis inherited his father's hyper-perception, sensing ki from thousands of miles away by age eight. In the evening, Kashu returned home. His three wives—Launch, Bulma, and Tights—were chatting in the living room. His three children were in their respective rooms doing homework. "You're back," Tights looked up. "How was training today?" "Very good," Kashu sat on the sofa, and Bulma immediately leaned in. "Kashu, Vegeta asked me to go to the movies today!" Bulma said excitedly. "He called it 'training to observe Earth culture,' but I know it was a date!" "Congratulations," Kashu laughed. "Aren't you jealous?" Bulma blinked. "Jealous of what? You're my wife, and he can't take you away." "You're so boring," Bulma pouted. Launch walked over with a cup of tea: "Kashu, have some tea." "Thank you, Launch." Tights adjusted her glasses: "Kashu, I wrote a new book about Cell. I want you to see if there are any inaccuracies." "Alright, I'll look at it tomorrow." Three wives, three kinds of love. Kashu felt fortunate to have transmigrated into this world and met them. He went upstairs to check on the children. Kariel was practicing punches in her room, hitting a sandbag over and over, sweat soaking her hair. "Kariel, it's time to rest." "Just a little longer, Dad. I'm going to surpass you!" "We'll see when you're older." Kabrun was reading in her room, her desk piled high with physics, chemistry, and biology textbooks. She was only eight, but she was already studying high school courses. "Kabrun, don't overwork yourself." "I'm not tired, Dad. Learning is very interesting." Kassis was meditating in his room, his silver eyes closed, his aura as calm as water. "Kassis, how do you feel today?" "Dad, I can feel it. A very powerful aura is approaching in the universe." Kashu's pupils contracted: "What kind of aura?" "I don't know. But it's very powerful, even stronger than Cell." Kashu was silent for a moment, then said: "Keep sensing. Tell me if anything changes." "Okay." A new threat—the powerful aura Kassis sensed was approaching Earth from the depths of space.

It was the God of Destruction Beerus and his Angel Whis. Beerus had learned from the Oracle Fish's prophecy that a warrior called the "Super Saiyan God" would appear in a few decades and become his rival. He decided to wake up early to go to Earth and find this legendary warrior. On Earth, Kashu also sensed Beerus's aura. "The God of Destruction... he's finally here." Kashu clenched his fists. Kariel, Kabrun, and Kassis looked at their father, not knowing what was happening. But they knew that a new battle was about to begin.
