After Louis returned to the God of Destruction Realm, three more years passed.
In these three years, Universe 7 underwent earth-shaking changes.
Because the Saiyan joined the Galactic Patrol Headquarters, the organization grew stronger by the day, and in the North Galaxy, the Frieza Force began to be suppressed.
This was mainly due to a shortage of manpower in the Frieza Force, as Frieza's strongest subordinate, Ginyu, only possessed a combat power of 120,000.
As for the Saiyan race, ever since they joined the Galactic Patrol Headquarters, their combat power had skyrocketed for reasons unknown.
Nowadays, every Saiyan possessed at least 15,000 combat power.
The strongest Saiyan was a man named Bardock, whose combat power had broken through to 150,000!
King Vegeta was also not to be underestimated, boasting a combat power of 120,000.
The entire Saiyan race numbered over two thousand people!!
Their overall strength was formidable!
However...
No matter how impressive they were, if Frieza were to take action personally, the current strength of the Saiyan would be of no use, even if every single one of them transformed into a Great Ape!
But because Louis and Tights had visited the Frieza Force headquarters three years ago, Frieza knew Louis's identity and dared not act rashly.
He also dared not openly hunt down the Saiyan, which was one of the reasons the Saiyan were able to steadily improve their strength.
Beyond the aforementioned changes in Universe 7, the average human level index had also risen significantly, moving from second-to-last to third-to-last.
This change left the Gods of Destruction from other universes dumbfounded.
Over a decade ago, Beerus had made a terrible decision to let a little brat become a Candidate God of Destruction.
Now, 14 years later, not only had Universe 7 not been destroyed by Zeno, but its ranking had actually risen by one spot.
As Universe 7 changed, Earth changed as well.
Although Earth was not directly interfered with by Louis, the plot of Earth still proceeded normally.
However, Earth was still affected by the butterfly effect: four years ago, Louis had asked Tights to have Dr. Briefs build a gravity chamber for Son Goku to use.
Son Goku used the gravity chamber, and his combat power improved significantly.
However...
Son Goku belonged to the slow-growth type of Saiyan, so his combat power did not increase in an exaggerated manner.
Today, 14 years after being sent to Earth, the 17-year-old Son Goku only possessed 5,000 combat power.
Beyond this change, four years later, three visitors from outer space appeared on Earth.
These three invaded Earth a full three years earlier than in the original story!
At Kame House.
"Goku, these three auras are extremely evil and exceptionally powerful. Can you handle them?" Krillin stood at the door, staring fixedly at the sky.
"I don't know, but if they want to harm Earth, I won't let them get away with it." Son Goku looked at the sky as well, his voice sounding youthful.
The 17-year-old Son Goku was still a child because he belonged to the slow-growth type of Saiyan; he would only suddenly grow tall once he reached adulthood.
This was different from Louis and Vegeta.
"I didn't expect that on the very day Goku was supposed to go to the Lookout to train, enemies would invade Earth." Master Roshi's face was filled with worry.
"You guys stay here; I'll go over and see what's going on first."
Son Goku took to the air and flew toward the direction where the three spaceships were landing.
On the outskirts of West City.
Vegeta, Raditz, and Nappa emerged from their ships.
Each of them was in rags, with caked blood staining their bodies, looking extremely disheveled.
"Damn it, Frieza wouldn't let us return to the Galactic Patrol Headquarters at all!"
Raditz lay on the ground, gritting his teeth. "But fortunately, Frieza's elite troops didn't come out personally, otherwise..."
"Vegeta, what do we do now? We've been running for 14 years; are we going to keep running?" Nappa asked bitterly.
"Shut up!"
Vegeta clenched his fists. "It's been over a decade; why hasn't Louis returned yet? If Louis came back, Frieza would surely be torn to shreds!"
Vegeta still remembered the scene from fourteen years ago when Louis was taken in by the God of Destruction Beerus as a Candidate God of Destruction.
That was a Candidate God of Destruction!
Who would dare provoke him!
"That's right, if Louis were back, we wouldn't be in such a sorry state."
Raditz and Nappa nodded one after another.
"Enough, stop saying useless things. This planet is the one Kakarot was exiled to. Let's go find him; one more person means one more bit of strength!"
Vegeta shook his head and pressed the scouter on his ear.
[Beep! Beep! Beep!]
[Southeast direction: Power level 2000!]
"What is going on? A power level of 2000?"
Vegeta was startled and checked again, only to find there was no error.
"Vegeta, could this be the power of Kakarot? Why would a low-class warrior like him be this strong?"
Nappa also checked once and was taken aback.
One must know that among the three of them, Vegeta was the strongest with a power level of 30,000.
He himself possessed a power level of 8000, while Raditz stood at 2000.
The data for the three of them was significantly higher than their power levels during the invasion of Earth in the original work.
This was because the three had been constantly hunted by the Frieza Force, forced to face life-or-death situations at every turn.
"A power level of 2000 is indeed hard to believe. If it really is Kakarot, then we have gained another source of strength."
Vegeta looked up at the sky in the southeast.
"He's coming!"
Raditz clenched his fists. The power of the person approaching was identical to his own, making him grow cautious.
Whoosh!
A beam of white light descended from the sky.
"Who are you people?"
Son Goku looked at the three ragged figures in front of him and asked in a stern voice.
Given his youthful voice and small stature, Vegeta and the others couldn't help but be stunned for a moment.
However, Raditz quickly recognized Son Goku's identity: "Vegeta, it's Kakarot. He looks exactly like my father."
Vegeta also realized why the other party was still so small, saying: "Born with only a power level of 2, low-class warriors grow slowly, but I estimate he will reach adulthood in another year."
"Who exactly are you? Why have you come to Earth?" Son Goku knitted his small eyebrows together.
Earth?
He must be referring to this planet.
Vegeta checked his scouter again and found many other readings that were pitifully weak.
"Kakarot, you haven't killed the people on this planet yet?"
Nappa was stunned and said: "You haven't wiped them out? That's not right. With a power level of 2000, he should have slaughtered the natives here long ago."
Raditz shouted: "Kakarot, what is the meaning of this?"
Son Goku looked at the three of them, puzzled: "Tell me, why are you here? And who is Kakarot?"
As soon as these words were spoken, the three of them looked at each other, seeing the confusion in each other's eyes.
"You aren't Kakarot?"
Raditz was taken aback, but looking at Son Goku's appearance, he was the spitting image of Bardock: "No, you must be Kakarot!"
Vegeta and Nappa nodded; Son Goku simply looked too much like Bardock.
"..."
Son Goku scratched his head, completely bewildered. He was clearly Son Goku, so why did these three guys keep calling him Kakarot?
Vegeta asked: "Do you know that you are a Saiyan?"
Son Goku blinked his small eyes and replied: "What is a Saiyan?"
Raditz and the others exchanged glances again. There was no doubt about it; he had forgotten about the Saiyans.
Raditz hurriedly asked: "Did you injure your head when you were a child?"
"How did you know I hurt my head?"
Son Goku pouted his small lips and said: "I fell off a cliff when I was little and hit my head. It was Grandpa who saved me and brought me back."
These were all things his grandfather had told him.
Thinking of Son Gohan, Son Goku's mood dampened.
"Just as I thought!"
Raditz held his head and looked at Vegeta, saying helplessly: "Vegeta, what do we do now?"
"If we were still following the Frieza Force, I wouldn't hesitate to slaughter everyone on this planet and sell it off."
Vegeta's gaze sharpened: "However, since we Saiyans have joined the Galactic Patrol Headquarters, we can no longer do such things."
Raditz and Nappa recalled this as well.
Years ago, after the Saiyans followed the orders of the God of Destruction Beerus and joined the Galactic Patrol, they no longer obeyed the commands of the Frieza Force.
Nowadays, the Saiyans acted more like mercenaries within the Galactic Patrol, taking on missions issued by the Galactic Patrol Headquarters every day and no longer engaging in burning, killing, or looting.
Raditz looked at Son Goku and said, "Your real name is actually Kakarot. I am your brother, and neither of us is from Earth."
"My name is Son Goku, I am an Earthling, and I am definitely not your younger brother!"
Son Goku clenched his fists, angry.
He was clearly an Earthling; why did these people keep saying he wasn't?
Influenced by his anger, his hidden power began to leak out.
"Beep, beep, beep!"
Combat Power: 3000! Combat Power: 3500!
Combat Power: 5000!
Son Goku's combat power soared all the way, finally stopping at 5000.
Nappa's eyes widened: "How is that possible!"
Raditz swallowed hard: "This has to be fake, right? Isn't he a low-class warrior? Why is his power stronger than mine, a high-class warrior?"
Vegeta's gaze sharpened: "This must be his true combat power. The fact that it was only 2000 before means he was hiding it."
Vegeta saw through Son Goku's secret at a glance. He stepped forward and said, "Saiyan never use techniques like this. This planet has something interesting going on!"
It was clear that Son Goku must have learned this concealment technique on this planet.
"Kakarot, where did you learn this technique?"
Vegeta flashed behind Son Goku and grabbed his small shoulder.
Son Goku erupted with a burst of power, shaking off Vegeta's hand. He leaped forward a few meters and said angrily, "My name is Son Goku, and I am an Earthling!"
"Tell me, are you here to harm the Earth?"
"Rest assured, we have no intention of harming the Earth."
Vegeta twisted his wrist; being shaken off by the kid actually stung a bit.
"Really?"
Son Goku asked innocently, no longer angry.
"Really!"
The corner of Vegeta's mouth twitched slightly. This kid was so easy to fool.
However, what he said was indeed true; he had no intention of harming the Earth, and in fact, he had become somewhat interested in the martial arts of this planet.
"Then I'll take you to learn how to control ki. To be honest, I haven't even fully mastered it myself. I was just about to head up to the Lookout to train when you guys arrived from the sky."
Son Goku tilted his head, blinking his large eyes, looking adorably clueless.
Son Goku flew into the sky, and the three of them, Vegeta, Nappa, and Raditz, exchanged glances before following him.
And just like that, through a twist of fate, the three Saiyan "invaded" the Earth.
However, instead of wantonly destroying the planet as in the original story, the three followed Son Goku up to the Lookout to receive guidance from Popo.
