And so, time passed day by day, and before long, a year had gone by. Everyone's strength had improved significantly, and now they were all waiting for the Saiyans to arrive on Earth.
That day, while Goku was still training with John Doe, he received a message from King Kai.
"Goku, the two Saiyans will arrive on Earth in less than a day. You'd better be prepared," King Kai said, sending the message directly to Goku's mind from the planet of King Kai.
Of course, it wasn't just Goku who received a message. God also sent a message to the Z Warriors who were training in the Temple of the Gods.
John Doe saw that Goku had suddenly stopped what he was doing, so he asked, "What's wrong, Goku"?
Goku replied, "King Kai just told me that the Saiyans will arrive on Earth in less than a day."
"Really? That's great. This time, we'll give them a lesson they'll never forget, so they won't dare to invade Earth again," John Doe said.
John Doe didn't think it was necessary to kill them. In the Dragon Ball storyline, Raditz would die because Goku had no other choice. If he didn't kill Raditz, Goku and everyone on Earth would die, including Chi-Chi and Gohan.
But if given the choice, Goku would never choose to kill his brother. So later on, when Nappa and Vegeta arrived on Earth, Nappa was killed by Vegeta, and Vegeta was let go by Son Goku.
So as long as those three Saiyans didn't act recklessly, John Doe could let them go too.
After finishing their training, Goku called back Piccolo and Gohan, who were training far away. Everyone prepared to take a good rest in the remaining day, getting ready for the battle the next day.
The next day, Goku, John Doe, and Piccolo, who were all very strong, could sense three powerful auras outside the Earth, one of which was particularly strong. Sensing this aura, even Piccolo felt a lot of pressure.
Piccolo looked at Goku and John Doe and asked, "Son Goku, John Doe, can you handle the strongest of those three enemies?"
John Doe and Goku smiled at each other, and John Doe said confidently, "Don't worry, Piccolo. Until you defeat us, no one can defeat the two of us."
After hearing John Doe's words, Piccolo was immediately silenced and rolled his eyes in speechless frustration.
Based on the location and speed of the auras, everyone flew towards the landing point of the spaceship.
But when they arrived, they found that the spaceship's landing point was actually a city.
"We can't let them land here. Otherwise, the residents of this city will be in trouble," Goku said.
"Let's choose another battlefield and emit our auras to attract the attention of the invading Saiyans. If they sense our auras, they'll definitely fly towards us," John Doe said.
Everyone agreed with John Doe's suggestion, so they chose a more remote wasteland as the battlefield and emitted their auras to attract the attention of the Saiyans.
In the space above Earth, Vegeta's battle power detector suddenly sounded a loud alarm.
Vegeta took a look and his face changed immediately. The detector showed several battle powers in the thousands and tens of thousands, gathered in one place on Earth, as if they were waiting for them.
Nappa's anxious voice also appeared on the detector, as he was asking Raditz, "Raditz, what's going on? Why are there so many people with such high battle powers on this planet?"
Raditz was also nervous and confused. He said, "That's not right. I remember that a year ago, apart from Kakarot, everyone else's battle power was only in the hundreds. Why has their battle power increased so much in just one year?"
"Hmph, you don't know. Is it because you've been lying to us all this time?" Nappa suspected that Raditz was up to something.
"Nappa, you're slandering me. Why would I want to set a trap for you with the Earthlings?" Raditz was anxious to defend himself in front of Vegeta.
"Who knows what you're up to? Maybe after seeing your brother Kakarot, you felt a sense of kinship and wanted to kill Nappa and me," Nappa said.
Raditz was even amused by Nappa's reason. He sneered, "Nappa, you're joking with me. Do Saiyans have any sense of kinship?"
Vegeta was annoyed by their bickering and immediately spoke up, "Both of you, shut up. No more wild guesses. Anyone who keeps arguing, I'll kill them!"
Immediately, the communication channel of the detector fell silent, with only the sound of three people breathing.
After a while, Vegeta spoke up, "Since they have no intention of hiding their battle powers, that's good. It saves us the trouble of looking for them. Let's go straight there."
"You don't need to worry about them. Although their battle power is strong, we have a trump card. This time, I deliberately chose to come at the time of a full moon. If our normal strength is not enough, we can transform into Great Apes."
"I don't believe that even after our strength increases tenfold, we won't be able to defeat them," Vegeta said harshly.
After hearing Vegeta's words, Nappa and Raditz, who had been very nervous before, felt much calmer.
Yes, we can still transform into Great Apes. Even if our Great Ape forms can't defeat those Earthlings, Vegeta's Great Ape form can. In the end, it will still be our victory.
And so, the three egg-shaped spaceships drew a semicircle in the sky above the city and then flew away.
The people in the city were all startled. Just now, everyone thought that three huge meteorites were about to fall, and they all drove out of the city in a panic.
Fortunately, they turned away in the end, but even so, they still scared the people in the city.
On the battlefield chosen by the Z Warriors, as Vegeta and the others were turning the spaceship, Goku immediately reminded everyone, "Be careful, they're coming!"
Then everyone looked up and saw three small spaceships flying towards them at high speed.
As the spaceship flew over everyone's heads, both sides stared deeply at each other through the spaceship's porthole.
Finally, the spaceship flew over and landed not far away, leaving three deep craters on the ground.
John Doe said to everyone, "Let's go and welcome our distant guests. At least we should let them know how warm and hospitable we are."
"Yes!" Everyone immediately raised their hands in agreement and flew towards the landing point of the spaceship.
