"So, a Super Saiyan 4 transformation requires a tail! But neither Vegeta nor I have tails anymore. What's going on?"
Goku asked, utterly confused.
"Once a person's power in their base form surpasses that of their Great Ape form, the tail will no longer grow back," Gogito explained.
"So, that means only Kid Gohan can grow a tail now."
"Huh??"
Goku felt a bit dejected. Seeing the Super Saiyan 4 form, he really wanted to try transforming into it himself.
"If it can't grow back naturally, you can use external force. Doesn't Earth still have the Dragon Balls?"
Gogito's words brought Goku back to life instantly.
"That's right! Earth still has the Dragon Balls!" Goku said excitedly.
Vegeta was also stirred by the idea. If he could become a Super Saiyan 4 before Kakarot, he would finally be able to surpass him.
At the thought of this, Vegeta clenched his fists in excitement.
Following this, the group began their training inside the Hyperbolic Time Chamber.
Elsewhere, the two Bulmas were discussing something.
"Truly amazing. To think of such a brilliant machine and even have the blueprints—I really am incredible," Bulma said, looking proud.
In front of her lay a stack of blueprints; indeed, they were the designs for the Time Machine.
"Although the blueprints exist, they aren't perfect yet. There are still some issues that need resolving, and I need your help," Future Bulma said to Bulma. She knew that her younger self was just as talented and could help her complete the construction of the Time Machine.
With Bulma's help, the Time Machine might appear earlier than it did in the original timeline. Although there was no longer a need to use it to return to the past, Future Bulma still wanted to create it. It was the fruit of her labor for so many years; how could she just give up on it?
The two began their grand project of researching the Time Machine.
As for Tights, she was busy gathering information about the Androids. After witnessing the tragedy of this world, she felt an urgent need to write the story of this world into a novel.
Tights hopped into her plane and flew everywhere searching for survivors, telling them the news that the Androids had been defeated.
However, people didn't believe her, as the cunning Androids had used this trick before to lure hidden humans out and slaughter them.
Tights did not lose heart, though; she continued to travel from place to place, spreading the word that the Androids had been wiped out.
In one particular region, people discovered the debris of the Androids that Vegeta had blasted to bits, and finally, they believed they were dead. The news spread rapidly—from one person to ten, from ten to a hundred. Before long, all the survivors on Earth knew. People poured out of their shelters to cheer, their voices ringing out to the heavens.
The rising sun seemed to be celebrating this hard-won peace as well.
Now, at Bulma's house, the recently resurrected Krillin, King Piccolo, Tien Shinhan, Master Roshi, and the others were discussing their future strategy.
They had previously visited Grand Kai's Planet and witnessed the martial arts atmosphere there, which had left a deep impression on them. Back then, when they were dead, they hadn't thought much of it, but now that they were resurrected and Earth had suffered so many disasters, they wanted to make the people of Earth aware of martial arts, learn them, and develop Earth into a planet similar to Grand Kai's Planet.
First, King Piccolo ruled the world, then the Saiyan invasion, the resurgence of Frieza, and now the rampage of the Androids—Earth had endured too many catastrophes.
They had to ensure that Earthlings had the ability to protect themselves. They didn't expect them to be able to eliminate invaders, as the enemies were becoming stronger each time.
The aliens were all monsters. At first, Krillin, Tien Shinhan, and the others could barely keep up, but later they gradually fell behind, eventually only able to watch as Goku grew stronger and stronger.
Yamcha had recognized the reality and started to let himself go. Perhaps that was why Bulma had seen through him and broken up with him. Her man didn't have to be the strongest, but he couldn't lose his fighting spirit or his dreams. And it just so happened that Vegeta appeared before Bulma at that very moment.
At that time, Vegeta didn't feel despair because Goku had transformed into a Super Saiyan; on the contrary, he trained even harder, even if he was often cursing and swearing.
Moreover, his attitude toward Bulma was of the domineering type. When Bulma first met Yamcha, he was also arrogant, spirited, and invincible. Upon meeting him, Bulma had been attracted to that side of Yamcha, but at some point, Yamcha changed. He became timid and even acted weak when facing her. Eventually, they had a peaceful breakup, which ultimately benefited Vegeta.
Tien Shinhan, however, did not change; he continued to train diligently. During the Majin Buu era, Tien Shinhan was still training in the deep mountains, but whenever Earth faced a crisis, he would still step forward. It could be said that Tien Shinhan was the most outstanding martial artist on Earth.
Although Krillin also saw the reality of the situation, he didn't give up. He continued to train hard, quietly doing his part. By the Super era, Krillin chose to become a police officer, still silently guarding the Earth.
At the Tournament of Power, all of Earth's warriors participated, except for Yamcha. Perhaps this was the reason; they all saw that Yamcha's heart for martial arts had shattered.
These were matters for another time.
The immediate priority was to rebuild their home and then promote martial arts.
As for how to develop martial arts, they didn't have any good ideas yet.
Inside the Hyperbolic Time Chamber, Three months had passed inside.
Goku was training the two Gohans. Kid Gohan needed to build a solid foundation, so his power hadn't increased too drastically, but he still had a combat power of over ten thousand. Goku taught him techniques, the control and application of Ki, and some energy wave skills. Even so, Kid Gohan's power had seen a massive increase—dozens of times greater than before.
Future Gohan was also learning along with him, as he had never truly been taught and had figured everything out on his own. If Future Gohan's foundation were properly laid, those two Androids would be no match for him.
In the Cell era, Gohan had gone from not being able to transform into a Super Saiyan to reaching Super Saiyan 2 in less than a year. Part of this was due to Gohan's talent, but another part was the foundation Goku had laid for him. Goku had taken many detours on his own journey, so when he taught Gohan, he could help him avoid those same mistakes, allowing him to advance by leaps and bounds.
Having someone to clear the path ahead was a completely different concept.
Now, Future Gohan had reached Super Saiyan Full Power and was only one step away from transforming into Super Saiyan 2.
Vegeta was teaching Trunks. He had high hopes for his son and wanted him to surpass Kakarot's son, but Trunks idolized Future Gohan so much that it made Vegeta incredibly annoyed, forcing him to increase the intensity of the training. Now, Trunks was one step away from reaching Super Saiyan Full Power.
Vegeta trained Trunks while also training himself; he had already mastered the power of Super Saiyan 2 and had progressed quite a bit further.
Gogito was busy familiarizing himself with Super Saiyan 4. Thanks to Vegito's talent, Gogito's training speed was lightning fast. He had mastered the Super Saiyan 4 transformation and was halfway to reaching Super Saiyan 4 Full Power.
