Time passed quickly, and within a short while, a year had gone by in the Spirit Time Chamber.
Although Goku's physique among the Saiyans was that of a lower-class warrior, it must be said that Goku truly lived up to his role as the protagonist in the Dragon Ball universe. It seemed that the entire fate of the Dragon Ball world was gathered within him.
Regardless of whether they were his companions or enemies, and regardless of how much stronger they were than Goku before they met him, Goku always managed to catch up in a very short time.
Even someone like John, a time traveler with precognitive abilities, was no exception. In just a short time of training in the Spirit Time Chamber, Goku's strength had already caught up with John's.
This was the first time the two had fought to a draw in the Spirit Time Chamber. Both of them were covered in wounds, their faces bruised and purple, and blood hung from the corners of their mouths.
Goku looked at John with a happy face and said with a laugh, "Haha, John, I finally caught up with you!"
In contrast to Goku's happiness and joy, John was feeling quite dejected. He couldn't understand why he and Goku, both being Saiyans, had such a vast difference in the rate of strength improvement, especially considering Goku's status as a lower-class warrior.
The only explanation could be that Goku was the protagonist of the Dragon Ball universe, blessed with immense cosmic fortune. As the protagonist, this fortune dictated that Goku could never be weaker than anyone else, be they friend or foe.
John took out two Senzu Beans, gave one to Goku, and ate the other himself. Instantly, both of them were restored to their peak physical condition.
John said, "Alright, Goku, let's end our training for today. Now that your strength has caught up with mine, we need to change our training methods. I'll also tell you about the Saiyans."
Goku was taken aback but followed John into the palace within the Spirit Time Chamber.
The two didn't sit on the chairs but casually sat on the ground, and John began his explanation.
"Saiyans are not the original life forms of Earth; they are life forms from other planets in the universe. So, Goku, you were actually sent to Earth from another planet in a spaceship when you were very young."
"I won't go into detail about the current situation of the Saiyans; you can find out about these things later when you have free time, or you can investigate them yourself. Anyway, it's pretty boring stuff."
"What I'm going to tell you next is the most crucial thing. Right now, we are in the state of ordinary Saiyans. Although we can improve our strength through training, this improvement will eventually slow down and become increasingly gradual, to the point where the increase in strength is almost negligible."
"Therefore, the ancestors of the Saiyans chose to evolve in order to enhance their cultivation faster. They evolved from ordinary Saiyans to Super Saiyan 1."
"Then from Super Saiyan 1 to Super Saiyan 2, and from Super Saiyan 2 to Super Saiyan 3."
"In theory, Super Saiyan transformation can continue indefinitely, but just like with ordinary Saiyans, Super Saiyans will also find it increasingly difficult to continue improving after reaching a certain level."
"At this point, they need to find a new path of evolution."
What John had said about the Saiyans had already left Goku feeling dizzy and bewildered. He had never imagined that there could be a higher level of evolution beyond Super Saiyan 1, 2, and 3.
Goku couldn't help but ask, "Is there a Super Saiyan 4?"
John nodded and said, "Super Saiyan 4 definitely exists, but in this universe, the rulers of all life are the Gods."
"So, our path of evolution should be towards becoming Gods."
"Gods?" Goku was a bit confused. "John, do you mean the Earth's God?"
John shook his head and said, "The Earth's God isn't that powerful. They are merely managers of a planet and the lowest-ranking gods in the entire universe's divine hierarchy."
"Above the Earth's God is the King of the Underworld, who is in charge of managing the afterlife and the souls of the dead. Your grandfather is also under his jurisdiction. When the Fortuneteller Baba brought your grandfather back, she needed the approval of the King of the Underworld."
"Above the King of the Underworld is the King of the World, and above him is the Grand King of the World. Above the Grand King of the World is the King of the Worlds."
"In a universe, the King of the Worlds is the highest-ranking god."
"Does that mean the higher the rank of the god, the stronger their power?" Goku asked curiously.
"Not necessarily," John explained. "These gods, kings, and kings of the worlds are managers of a universe, a galaxy, or a planet, and their strength may not necessarily be the greatest."
"Oh..." Goku felt a bit discouraged after hearing John's words. He had thought that these gods were all very powerful, but it turned out that their strength might not even be as great as his own.
"Since the strength of these gods is not as great as ours, why do we need to evolve towards becoming gods?" Goku asked.
John continued to explain, "Goku, let me first tell you that evolving into a god is not the only path. However, since gods exist, I believe it's better to follow this well-established path rather than trying to figure it out on our own."
"Although the King of the Worlds and the King of the Worlds of the Worlds are not that powerful, the God of Destruction, who holds the same position as the King of the Worlds of the Worlds, is a formidable powerhouse."
Goku was surprised to learn that there was also a God of Destruction, a name that sounded very domineering. So, he excitedly asked John, "John, how powerful is this God of Destruction?"
John thought for a moment, unsure how to describe it to Goku. After a brief silence of about ten seconds, John said, "The God of Destruction can casually release a tiny bit of his power and destroy an entire planet."
"How tiny is this bit of power? It's probably one-millionth, or even one-hundred-millionth, of his full power."
"Wow! That's incredible!" Goku exclaimed in astonishment. Everything John had explained so far completely shattered Goku's understanding, leaving his mind in a state of confusion.
Just as Goku was marveling at the power of the God of Destruction, John continued, "The God of Destruction is not the most powerful being in the universe."
"What? There's someone even more powerful than the God of Destruction?!" Goku, who was still digesting the power of the God of Destruction, was immediately surprised to hear that there was someone even stronger.
