The Blue Planet

In the Cosmic Era of AGE 738, on Earth, a rugged, medium-sized spacecraft pierced the atmosphere and landed on Mount Paozu, a place surrounded by mountains.

The moment the hatch opened, a breath of fresh air surged into the cabin. The scent of green grass, the fragrance of wildflowers, and the crisp smell of earth after rain felt both strange and novel to every Saiyan stepping out of the ship. On Planet Vegeta, the air was always dry, filled with dust and the stench of blood. Here, however, the air seemed to carry a hint of sweetness. Kashu stepped off the ship, cradling the one-year-old Kakarot in his arms. His younger brother looked around curiously, his large eyes filled with wonder. At one year old, Kakarot was much sturdier than human infants of the same age and could already speak simple words.

"Brother, where... is this?" Kakarot asked in a muddled voice. "This is Earth, our new home," Kashu replied with a smile. Bardock was the last to exit the ship. He surveyed the surroundings—the lush forest, the clear stream, the rolling mountains in the distance, and the deep blue sky above. "This is Earth?" Bardock took a deep breath. "It is indeed completely different from Planet Vegeta. The gravity is only one-tenth of that on Planet Vegeta, and the oxygen content in the air is higher. It is very suitable for training." Kashu said, "We will establish a temporary base here first, then expand it slowly." Over the next few days, the 120 Saiyans began building a camp on Mount Paozu. With the physical prowess of Saiyans far exceeding that of humans, combined with various tools salvaged from the ship, a simple yet fully functional camp was completed in less than a week.

The camp included a residential area (fifty wooden cabins), a training ground (a leveled clearing with a simple gravity room), a research area (a laboratory converted from the ship's cabin), and a supply warehouse.

Bardock organized the fifty warriors into five squads of ten, responsible for patrolling, training, and defense. Among the fifty female Saiyans, twenty scientists were assigned to the research group, led by Gine (though Gine herself was not a scientist, she was skilled at coordination), while thirty technicians were responsible for camp maintenance and logistics.

The eighteen children formed a "Youth Group," led by Kashu. That's right, five-year-old Kashu had become the leader of eighteen Saiyan children. "Brother Kashu, when can we start training?" asked a four-year-old boy named Laya. "Yeah, yeah! I want to fight just like my dad!" a three-year-old girl named Sali waved her small fists. Kashu looked at this group of hyperactive Saiyan children and felt a headache coming on. The Saiyan gene for combat manifested from a young age, making it nearly impossible to keep them still. "Starting tomorrow, we will have basic physical training every morning and study culture and science in the afternoon," Kashu announced. "Huh? We have to study?" the children wailed. "No study, no food," Kashu said with a straight face. The children immediately shut their mouths. The Saiyan obsession with food was etched into their genes...

A month later, the camp had basically stabilized. Kashu handed the daily affairs over to Bardock and Gine, while he began to focus on two important tasks: first, finding the Dragon Balls, and second, finding martial artists on Earth. "System, scan for the locations of the Dragon Balls on Earth." [Scanning...] [Scan complete. The seven Dragon Balls are distributed as follows:] Four-Star Ball: Near Mount Paozu (5 km in a straight line); One-Star Ball: Eastern Desert region; Two-Star Ball: Northern snowy mountains; Three-Star Ball: Western city area; Five-Star Ball: Southern island; Six-Star Ball: Central plains; Seven-Star Ball: An unknown space (suspected to be kept by the Lookout).

"The Four-Star Ball is right on Mount Paozu?" Kashu was a bit surprised. According to the original story, the Four-Star Ball should be Grandpa Son Gohan's heirloom, hidden in his home. But in this timeline, Son Gohan should still be a young man, so the Four-Star Ball might still be in its original place. Taking Kakarot with him, Kashu followed the system's guidance and found the Four-Star Ball in a cave on the east side of Mount Paozu. It was an orange orb the size of a fist, with four red stars floating inside. Kashu held it in his hand and felt a warm, ancient energy. "Is this a Dragon Ball?" Bardock walked over, looking curiously at the orb in his son's hand. "Yes. As long as we gather all seven, we can summon the Eternal Dragon and grant any wish," Kashu said. "But we are in no rush; let's find them slowly. The top priority is training." "Training?" Bardock frowned. "How do you intend to train?"

"Father, have you noticed that the spiritual energy on Earth is very rich?" Kashu asked.

Bardock nodded. "Indeed. The energy density in the air here is much higher than on Planet Vegeta." "That is because there is an energy called 'Ki' on Earth," Kashu explained. "Every living being has Ki, but humans don't know how to use it. If we can learn to sense and utilize Ki, our combat power will increase much faster." Bardock looked thoughtful. "Furthermore," Kashu continued, "there are many martial artists on Earth. Although their combat power may not compare to Saiyans, their fighting techniques and application of Ki are worth learning." "You want to take a human as your master?" Bardock's expression was subtle. Saiyans were a warrior race, inherently proud; asking him to take someone with far less combat power as a master was truly hard to accept. "Not as a master, but for exchange and learning," Kashu corrected. "Father, our goal now is to become stronger. As long as we can become stronger, any method is worth trying." Bardock was silent for a moment, then finally nodded. "You are right..."

In the autumn of AGE 738, Kashu left Mount Paozu for the first time to head toward human-inhabited areas. He took Laya (a four-year-old boy, the son of Bardock's comrade Reg) with him, under the pretext of "letting Laya see the world." In reality, Kashu wanted to find someone suitable—Master Roshi or Son Gohan—to teach the children the basics of martial arts. The two flew for about an hour and arrived at a large city called "East City." East City was one of the most prosperous cities on Earth, filled with high-rise buildings and bustling traffic, scenes familiar to Kashu from his past life. Although he had lived here for less than a year, the sense of familiarity was something Planet Vegeta could never provide. "Brother Kashu, what are those iron boxes?" Laya pointed at the cars on the road. "Cars, a type of transportation," Kashu said. "Similar to our ships, but they run on the ground." "So slow," Laya pouted dismissively. Kashu smiled and took Laya into a restaurant. The appetite of Saiyans was astonishing; even at five and four years old, the two of them could eat the portions of a dozen people in one sitting. Fortunately, Kashu had brought some precious metals from the ship and exchanged them for Earth currency, so they didn't have to worry about dining and dashing.

While eating, Kashu heard people at the next table talking about the "World Martial Arts Tournament." "I heard the next tournament is in three years, and many experts will participate! The champion of the last one was Son Gohan; that guy's martial arts are simply divine! His master, Master Roshi, is even more powerful, but he never competes."

Kashu's heart stirred. Son Gohan, Master Roshi. Weren't these the master and grandfather of Son Goku from the original story? He walked over to their table and asked politely, "Excuse me, may I ask where Mr. Son Gohan lives?" The humans looked Kashu up and down—a five-year-old child wearing strange clothes (Saiyan battle armor), with long, messy hair, looking like a wild child. "Kid, why are you looking for Mr. Son Gohan?" an older man asked.

"I want to become his student," Kashu said bluntly. The humans burst into laughter. "Kid, Mr. Son Gohan is a martial arts master; not just anyone can be his student. You should go home and find your mother." Kashu didn't get angry. He extended his right hand, and a visible ball of golden Ki condensed in his palm. The Ki orb rotated, expanded, and contracted, finally forming a small golden bird that flew above the table.

The laughter of the humans stopped abruptly, their mouths hanging open wide enough to fit an egg. "This... what is this?! Internal energy! It's the legendary internal energy!"

"This kid knows sorcery!" Kashu retracted the Ki and said calmly, "Now, can you tell me Mr. Son Gohan's address?" ... According to the information he gathered, Son Gohan lived on a small mountain about 300 kilometers south of Mount Paozu. When Kashu and Laya flew to that mountain, it was already dusk. The setting sun dyed the sky orange-red, and an old man with white hair but a straight back was practicing punches in the courtyard. His movements were slow and fluid, each strike and stance seemingly integrated with nature.

Son Gohan. Master Roshi's top disciple, the God of Martial Arts. Kashu landed at the gate of the courtyard, with Laya following closely behind.

Son Gohan stopped his practice and turned to look at these two uninvited guests. His gaze lingered on Kashu for a moment, then he frowned slightly. This child possessed an aura he had never seen before—powerful, pure, and carrying a sense of primitive strength. "Little ones, who are you?" Son Gohan asked. "My name is Kashu, and this is my younger brother, Laya," Kashu bowed. "We are Saiyans from outer space. I would like to ask you to teach us martial arts." "Saiyans? Outer space?" Son Gohan's eyebrows arched. Kashu didn't hide anything. He briefly recounted his origins (partially), the destruction of Planet Vegeta, and their experience of escaping to Earth. Son Gohan listened in silence for a long time. "How old are you?" Son Gohan asked. "Five." "Five years old and you have such strength?" Son Gohan's gaze became sharp. "The speed at which you flew here is faster than any martial artist I have ever seen." "Saiyan physiques are stronger than humans, but that doesn't mean we don't need to learn techniques," Kashu said sincerely. "Mr. Son Gohan, I have heard of your reputation. You are a true martial arts master, and I hope that my brothers and I can learn the spirit and techniques of martial arts from you."

Son Gohan looked into the eyes of this five-year-old child. There was no arrogance or murderous intent expected of a Saiyan, only a maturity and determination that transcended his age.

"Very well." Son Gohan nodded. "I can teach you martial arts, but I have one condition."

"What condition?" "You must use the martial arts you learn to protect the weak, not to bully them." Kashu smiled: "I promise you." From that day on, Kashu went to Son Gohan's place twice a week to learn martial arts. Laya and several other older Saiyan children followed as well. Son Gohan taught them not just fighting techniques, but the spirit of martial arts—how to control their power, how to remain calm in battle, and most importantly: the greater the power, the greater the responsibility. Bardock was initially skeptical about his son learning human martial arts, but when he saw Kashu's combat power increase from 1800 to 2500 in just a few months, his skepticism turned to surprise. "Are human martial arts that useful?" Bardock asked. "It's not that the martial arts themselves are useful, but their method of using 'Ki' is," Kashu explained. "Father, would you like to come and learn too?" Bardock hesitated, then shook his head: "I'm not used to bowing to others. But you can teach what you've learned to the other warriors." "Of course..."

In early AGE 739, under the introduction of Son Gohan, Kashu met the legendary Master Roshi. Master Roshi was a short, bald old man wearing sunglasses, a floral shirt, and large shorts, looking like an unserious old man. But Kashu could feel that within this seemingly comical old man, there was a formidable amount of Ki. "Gohan, you say this little brat is an alien?" Master Roshi circled Kashu twice, looking him over curiously. "Yes, Master," Son Gohan said respectfully. "He is a Saiyan, his combat power far exceeds that of ordinary people, but he is willing to learn our martial arts." "Combat power? What is that?" Master Roshi scratched his bald head. "I only know Ki. Little one, let me see your Ki." Kashu extended his right hand and released a ball of golden Ki. The Ki orb rotated and changed in his palm, finally condensing into a crystal-clear energy sphere. Master Roshi's expression changed. He had lived for over three hundred years and had seen countless martial artists, but he had never seen a five-year-old child who could release such pure and powerful Ki. "Good kid." Master Roshi dropped his joking expression. "This Ki of yours is much stronger than mine was when I was young. But you don't know how to control it, do you?" Kashu nodded: "Yes, Master Roshi. Although my Ki is strong, it is not refined, and I waste a lot of it in battle." "Then you've come to the right place." Master Roshi grinned. "I may not have other skills, but I have a knack for teaching people how to control Ki. However—"

"However what?" "You have to do one thing for me. Help me find a magazine, the latest issue of Fitness Girls." Master Roshi said solemnly. "It's sold out everywhere, and I've been looking for a long time." Kashu: "..." Beside him, Son Gohan covered his face, wishing he could find a hole to crawl into. Kashu eventually helped Master Roshi find the magazine (redeemed from the system store for 5 points). After getting the magazine, Master Roshi was grinning from ear to ear and immediately agreed to take Kashu as a registered disciple.

Although he was only a registered disciple, Master Roshi taught him very seriously. He didn't teach specific moves, but the fundamental method of controlling Ki—how to circulate Ki within the body, how to achieve the greatest effect with the least amount of Ki, and how to maintain the stability of Ki during battle. This knowledge was a treasure to Kashu. Although he had seen the use of Ki in anime in his past life, theory and practice were two different things. With Master Roshi's guidance, his ability to control Ki improved by leaps and bounds. New book, three things! Please read, please add to library, please tip!
