Goku and Chi-Chi's wedding went smoothly, held at King Ox's home. As Goku's friends, John Doe, Krillin, Yamcha, Bulma, Master Roshi, Turtle, Launch, Tien Shinhan, Chaozu, Oolong, and Pu'er all attended the celebration.
Everyone at the wedding banquet was filled with emotion, surprised that the youngest among them, Goku, was the first to get married.
Bulma reminisced about the days when she, John Doe, and Goku had set out together to search for the Dragon Balls. She couldn't believe how many years had passed since then. The once mischievous Goku was now a husband, while she was still searching for her Prince Charming.
Bulma glanced at Yamcha, who was chatting with some girls, and her dissatisfaction grew.
The wedding ceremony began, and Goku, in a white suit, and Chi-Chi, in a white wedding dress, walked down the aisle, greeted by thunderous applause.
When the host asked about Goku and Chi-Chi's love story, Goku stumbled over his words, unsure of what to say. Chi-Chi, however, confidently shared how she met Goku, how she pursued him at the World Martial Arts Tournament, and how they eventually got married.
Chi-Chi's story captivated the audience, revealing a girl's journey of falling in love with a boy. Everyone was moved by Chi-Chi's courage and warned Goku, "Goku, don't let Chi-Chi down. Don't ever look at other pretty girls and fall for someone else."
Goku looked bewildered at the mention of infidelity. He blinked a few times and asked, "What is infidelity? Can you eat it?"
The guests burst into laughter at Goku's innocence, reassured that such a pure-hearted person would never cheat.
However, what they didn't anticipate was that while Goku wouldn't cheat, he was obsessed with training. Except for the first few years after his marriage, he spent most of his time away from home, leaving Chi-Chi to raise their two children alone.
The wedding soon came to an end, and the guests gradually dispersed. But John Doe stayed behind to teach Goku his modified Kaioken and Instant Transmission, including Krillin, Yamcha, and Tien Shinhan.
Unfortunately, only Goku, who already knew the Kaioken, quickly mastered the improved version. The others lacked the necessary strength to use the Kaioken.
Based on Goku's power level when using the Kaioken in the manga, John Doe estimated that they needed to increase their power levels to 3000-5000 to use the technique.
As for Instant Transmission, it was a shame that only Goku had made some progress, while the others still couldn't use it due to their insufficient strength.
After training together for a while, they eventually parted ways.
Before leaving, John Doe reminded everyone, "There may not be any formidable enemies in the next few years, but don't slack off in your training. We are the strongest on Earth."
"But in the vast universe, our strength is still inferior. If invaders from space come to Earth, we must be ready to fight them."
Upon hearing John Doe's words, everyone except Goku was jolted. Their hearts, which had been relaxed, now stirred with excitement.
Goku nodded in agreement, "John Doe is right. I've heard from King Kai that the universe is far from peaceful. Planets like ours, suitable for life, are highly sought after."
"If our Earth is discovered by aliens, they won't let us off easily. They will find ways to occupy our planet, enslave us, and sell our planet for a good price."
"Rest assured, John Doe, Goku. We will continue to train hard and strive to master the Kaioken as soon as possible," Krillin, Yamcha, and Tien Shinhan said in unison.
And so, they parted ways, each embarking on a new journey of self-improvement.
As John Doe bid farewell to Goku and returned to West City, Android 17 and Android 18 also faced a significant crisis.
The two had taken advantage of John Doe's defeat of the Red Ribbon Army to escape from the organization.
Currently, they were starting a new life in a small town, unaware that they had been on Dr. Gero's radar for his modification plans.
Previously, due to their disobedience, Gero had been frustrated. But through his connections with the Red Ribbon Army's higher-ups, he learned that Dr. Gero had been collecting exceptional martial artists to transform them into Androids.
So, Gero had reported Android 17 and Android 18's names for the experiments.
However, he hadn't anticipated that John Doe would intervene, allowing the two to escape from the Red Ribbon Army.
By this time, Dr. Gero had set his sights on them, especially since they had managed to escape from John Doe. This gave Dr. Gero the misconception that they were powerful, and he believed that once they were transformed into Androids, they could defeat both John Doe and Son Goku.
Dr. Gero deployed his small robots to search for them across the Earth, eventually locating Android 17 and Android 18 in a small town.
In the quiet of the night, the town was peaceful. After a long day, Android 17 and Android 18 returned home, ate dinner, and retired to their rooms.
In the middle of the night, when everyone was in deep sleep, a squad of Red Ribbon Army soldiers stealthily approached Android 17 and Android 18's house.
At the commander's signal, the soldiers stormed into the house.
Android 17 was the first to react. He quickly got up and knocked down several soldiers who tried to attack him. Then he rushed towards Android 18's room.
However, as he reached the hall, a dozen soldiers fired tranquilizer guns at him. With a dosage strong enough to knock out an elephant, Android 17 staggered a few steps before collapsing to the ground.
As he wearily closed his eyes, he saw his sister being carried out of her room by the soldiers. Helpless, he closed his eyes and fell into a deep darkness.
The squad leader waved his hand, and the Red Ribbon Army soldiers took the two away from the town, heading towards Dr. Gero's laboratory.
A few years later, when Android 17 and Android 18 woke up, they were shocked to discover significant changes in their bodies. Dr. Gero, standing beside them, said with delight, "From today onwards, you will be known as Android 17 and Android 18. I am your creator, Dr. Gero, and your mission is to eliminate Son Goku and John Doe..."
