Inside the Parallel World Created by Buu

This world was almost identical to the main world. The only difference was that there were no androids, no Cell, and no Majin Buu. It was a peaceful world, free of war. Goku took a deep breath and sensed the energy in the air. "The energy here... is very pure," Goku said. "There's no pollution, no interference." Vegeta had already started warming up. "Enough talk. Let's get to training!" Kashu established a temporary base in the parallel world, using his divine power to create a vast training ground. Inside, time could be accelerated even further, to a ratio of 1:1,000. "One day of training here is equivalent to three years in the main world," Kashu said. "But be mindful of the strain on your bodies. Saiyan bodies can withstand intense training, but your minds might not."

"Your minds?" Gohan frowned. "In an environment where time is accelerated, your minds will age faster," Kashu said. "If we train here for a year, our minds will age by 365 years. Our bodies won't grow old, but our minds might not be able to take it." "What should we do?" Goku asked. "Meditate," Kashu said. "Set aside time every day to meditate and rest your minds. Buu will teach you how—he has the Grand Supreme Kai's memories." Buu nodded. "Buu can teach." The training began.

Goku and Vegeta began training to compress Super Saiyan 3. Kashu taught them to compress the power of Super Saiyan 3 into their base forms, just as he compressed his own ki. Gohan continued training in Mystic Form, trying to combine it with Super Saiyan 3 to create an entirely new form.

Cell focused on evolving his cells. He sought to make every one of them as powerful as those of his Perfect Form, so that even if he were blown to pieces, he could instantly reassemble himself.

Buu trained in the Supreme Kai's abilities. He wanted to master divine techniques such as teleportation, healing, and mind reading, and become a true divine emissary.

Kashu trained as well. God Form was only the beginning. He still had higher levels to break through to—God Form 2, and perhaps even a third stage.

Time flew by as they trained. One day, two days, three days... equivalent to three years, six years, nine years in the main world. Goku finally mastered the technique for compressing Super Saiyan 3. Even in his base form, he could now wield the power of Super Saiyan 3. His hair no longer turned gold, and his eyes no longer changed color, yet his battle power had increased by an entire order of magnitude.

Vegeta refused to be outdone. He found a path of his own: a hybrid form combining Super Saiyan 3 and Super Saiyan Second Grade. It was more ferocious and powerful than Goku's compressed form, but it also placed a greater strain on his body.

Gohan finally combined Mystic Form with Super Saiyan 3. His body began to change. He no longer looked like an ordinary human; he became taller and more elegant. His hair turned silvery white, his eyes deep blue, and a silver aura surrounded him. "This is... the ultimate form of Mystic Form," Gohan said, looking at his hands. "Beast Form."

Cell's cellular evolution also made a breakthrough. Every one of his cells reached the strength of those in his Perfect Form. Even if he were blown apart at the atomic level, he could reassemble himself in seconds. His body became more adaptable, allowing him to change shape at will—larger, smaller, harder, softer. He could do anything.

Buu mastered most of the Supreme Kai's abilities. He could use teleportation to travel to any parallel world, heal any injury with his healing technique, and read anyone's mind. His battle power hadn't increased by much, but his support abilities had raised the strength of the whole team by a level.

Kashu's God Form also advanced. He had reached the second stage. His hair turned pure white, his eyes pure gold, and a sacred halo surrounded him. His perception expanded across the entire galaxy, allowing him to sense planets tens of thousands of light-years away. But his heart grew colder. He no longer laughed, cried, grew angry, or felt sadness. His expression was always calm, like a still pool of water. He still loved Android 18, but that love had become a pure desire to protect her, stripped of all warmth.

Android 18 watched Kashu change, and a dull ache stirred in her heart. She began to regret letting him accept divine power, but she didn't say anything. She knew everything Kashu did was to protect them all. All she could do was support him in silence. The training in the parallel world lasted a full year.

Only one day had passed in the main world. Kashu opened a portal, and everyone stepped through. Their bearing had completely changed. They were calmer and more reserved, but each of them had confidence shining in their eyes. Bulma stared at her husband, her mouth falling open in surprise. "Vegeta, you... you look younger?"

Vegeta gave a snort. "That's the result of training. I can now wield the power of Super Saiyan 3 in my base form." "That's incredible!" Bulma clapped excitedly.

Goku walked up to Chi-Chi and smiled. "Honey, I'm back." Chi-Chi looked at Goku, tears streaming down her face. "You... why do you look older?"

Goku froze. "Older? No way. Only a day passed for us..." "It wasn't a day," Kashu said. "It was 365 days. Your mind aged by a year." Goku touched his face and did notice subtle changes—the fine lines at the corners of his eyes, the white hairs at his temples. But he didn't care. What mattered to him was his strength.

Evil Buu appeared the next day, stronger than ever. He hadn't wasted that day of "rest." Instead, he had absorbed a large amount of human energy and reached a new level of power. His body was more muscular, his skin had turned pure black, and the horns on his head had grown longer. His eyes no longer glowed red. They were pure darkness, like two black holes swallowing all light. "Earth Guardians," Evil Buu rumbled, his voice like thunder. "Your end has come."

Kashu stepped forward and faced Evil Buu. "Buu, I'll ask you one last time—are you willing to give up evil and return to goodness?" "Give up evil?" Buu laughed. "I am evil! Without evil, there is no Buu!" "Then there's no other choice." Kashu's ki erupted—not in a violent burst, but in a serene, sacred surge. His hair turned pure white, his eyes pure gold, and a sacred halo encircled him.

God Form 2. Evil Buu's pupils contracted sharply. "What is this power?" "Divine power," Kashu said. "Power beyond mortal limits." He moved.

He was so fast that Evil Buu's eyes couldn't follow him. One punch landed squarely in Evil Buu's chest. A huge hole tore through his body, its edges burning with golden light that prevented the wound from healing. "What is this...? This light is stopping me from regenerating!" Evil Buu cried in alarm. "Divine energy," Kashu said. "It can suppress your ability to regenerate." He attacked again and again, every punch leaving a wound on Evil Buu that refused to heal. Evil Buu groaned in pain. Against divine energy, his body was like paper—utterly defenseless. But Evil Buu didn't give up. He opened his mouth and fired a massive blast of energy. The blast roared toward Kashu, who raised a hand to block it. It ricocheted into space and shattered an asteroid.

"Too weak," Kashu said. "Is this the result of your training in the parallel world?" Only then did Evil Buu notice that Kashu's ki had risen by more than one level since before his training. That day of "rest" had actually been a year of hard training for the Earth Guardians. "You... you..." "We trained in a parallel world for a year," Kashu said. "You stood still." Evil Buu finally realized he had been tricked. Fear flashed in his eyes—he had never felt fear in his life before. "No... impossible... I'm the strongest!" "No," Kashu said calmly. "You're not." He brought his hands together and formed a golden sphere of energy before his chest. It was only the size of a fist, but the energy packed inside it was terrifyingly dense. Its sacred light illuminated all of West City. "What... is that?" Evil Buu asked, trembling. "Divine Judgment," Kashu said. "Your end." The sphere shot toward Evil Buu. He tried to dodge, but it had locked onto his ki. No matter how he moved, it stayed the same distance away. The sphere struck him. There was no explosion. No loud crash.

Evil Buu's body began to disintegrate from the edges inward, turning bit by bit into points of light. He screamed in terror and struggled, but divine energy had completely nullified his ability to regenerate.

"No... don't... I don't want to disappear..." More and more points of light appeared, and Evil Buu's body grew smaller and smaller. At last, he became a tiny ball of light that floated in the air for a moment before fading away. Evil Buu had vanished completely. It wasn't death, but a return. His energy returned to the universe and became part of the stars. His consciousness dissolved, leaving him unable to sense anything. Fat Buu stepped out from the crowd and looked at the place where Evil Buu had disappeared. Tears ran down his face.

"Buu... Buu lost his other half..." Kashu walked over and patted him on the shoulder. "No, you haven't lost him. You've gained your freedom." Buu looked up at Kashu. "Buu... what is Buu now?" "You're yourself," Kashu said. "Neither good nor evil. You're just Buu." Buu fell silent for a long time, then nodded. Buu understood.
