Four years later, when Gohan was four years old, Raditz would come to Earth and say to Goku, "My foolish little brother..."
Then he would be killed by his foolish little brother.
Now, if Raditz came again, he would probably die even more cleanly... Hm? No!
Ethan suddenly realized that a big reason for Raditz's arrogance was that he looked down on the power levels of Earthlings. Even his own younger brother, Goku, at that time had a maximum power level of only a little over four hundred, and could only raise it to around a thousand by concentrating all his energy to unleash a Kamehameha.
With that level of strength, Raditz could naturally act as contemptuous and mocking as he pleased.
But what about now?
Ethan did not know the exact value of his current power level, because he was not sure about the basic standards used by Frieza and his group.
But he was certain that even if Vegeta came now, he would not gain any advantage against him.
In that situation, could Raditz still remain arrogant?
On top of that, Goku habitually let "weak opponents" go, so Raditz would have a chance to save his life. After all, he was Goku's older brother, so everyone would give Goku some face before Raditz did something beyond redemption.
"Huh? This makes things interesting."
Would there be one more surviving Saiyan in the future?
Looking at Goku doing warm-up exercises across from him, Ethan was also curious whether someone like Raditz could be saved. After all, Saiyan temperaments and personalities were not exactly good.
"What's wrong?"
After finishing his warm-up, Goku saw Ethan standing there staring blankly at him. He thought something was strange with him.
"Nothing!"
Ethan saw that Goku had loosened up and nodded at him.
"Fifty times gravity, activated!"
"Let's begin!"
As Ethan flipped the switch, the gravity system started, and the number shown on the screen kept rising, quickly reaching fifty.
"Oh, oh, oh!"
Goku stood in a horse stance with his fists clenched, veins bulging on his forehead and body. The pressure of fifty times gravity exceeded his expectations.
Ethan was not in much better shape, barely able to maintain a standing posture. Although he was standing beside the control panel, he felt like he could not even reach out and touch it.
"Fifty times gravity... it really is a bit too much."
In this environment, let alone doing intense exercise, he could not even move. He felt as if an invisible mountain was pressing down on him, the immense weight making him want to just lie flat on the ground.
He knew lying down would not help. That was the advantage of gravity training. Even if you lay there, your body was still under tremendous pressure and forced to "train."
However, going past the limit was not training. It was easy to be crushed outright by the terrifying gravity. So everyone had always been very careful and cautious. Only a training fanatic like Son Goku would suddenly come up with the idea of jumping straight to fifty times gravity, and only Ethan would be willing to try it with him.
Everyone else had gathered in the next room, watching the situation in the training room through the monitor. Seeing the state Goku and Ethan were in, everyone was very worried, but including Chi-Chi, no one used the emergency controller nearby to turn off the gravity in the room.
"It's truly terrifying. They can actually still stand."
They were all martial artists who had undergone gravity training. Krillin and Tien Shinhan, for example, had already adapted to twenty times gravity and were now training under thirty times gravity.
Yoruichi performed even better. She had adapted to thirty times gravity, but had not challenged fifty times gravity.
As for Yamcha, he was currently training under twenty times gravity. He was gradually beginning to feel his limit, and his improvement was getting slower and slower.
Besides them, there were also a few instructors from the martial arts school present. They were among the earliest batches to join the school, outstanding students who had received guidance from several martial artists, including Goku. After achieving some results in their training, they chose to stay and work at the school, where they were responsible for teaching new students various basics.
These instructors, who had signed employment contracts with the martial arts school, also had the opportunity to use the school's gravity training room. It was a weakened version, without temperature control and with a maximum of only ten times Earth's gravity, but so far no instructor had successfully cleared it.
Many instructors had thought it was impossible for normal people to endure such a terrifying environment, until Krillin, Yamcha, and the others demonstrated sparring in a ten-times-gravity environment in front of everyone and dispelled their doubts.
These people, whose eyes had now been opened to a new world, soon learned that the several martial artists residing at the school could already endure much higher levels of gravity. For example, Goku, already known as the strongest man on Earth, could move freely in a thirty-times-gravity environment.
Now, they were even witnessing Goku challenge fifty times gravity with their own eyes...
Gulp!
The sound of someone swallowing was very obvious at that moment, but the person next to him did not make fun of him, because he himself was so shocked that he had forgotten to swallow his saliva, which was now running down the corner of his mouth. That looked even more embarrassing than the person beside him.
If it were a new student who had just joined the martial arts school seeing this scene, they probably would not be able to understand how terrifying what was happening before them really was.
But these instructors had all entered the gravity room before and knew exactly what it felt like.
Let alone fifty times, even five times gravity already felt like an unreachable realm to them.
"As expected... worthy of being the headmaster!"
As for Ethan, they all knew he was the champion of the 22nd World Martial Arts Tournament and also a powerful martial artist. Being able to endure such a terrifying environment like the headmaster was something they could still accept.
Ethan had his own income and was not officially on the martial arts school's payroll, but he lived nearby and often visited, so almost everyone at the school knew him.
While everyone was still in shock, Goku had already started moving. His posture was awkward, as if his feet were stuck to the ground, and it took all his strength just to lift one foot and take a step forward. That single step already made Goku gasp for breath.
None of the onlookers laughed at him. Instead, they were amazed all over again.
Being able to take a step and walk proved that Son Goku's body could withstand this level of gravity. Based on past experience, it would not be long before he could move freely in a fifty-times-gravity environment.
As Goku took his first step, Ethan actually moved as well, but no one noticed, since he was standing a little off to the side.
After a while, everyone saw Ethan and Goku in the gravity room begin running, or walking in circles, step by step around the room.
"Alright, you can all disperse. There's no danger."
No one had really been worried that the two of them were in danger. They had just wanted to confirm whether the gap between themselves and those two had widened again.
At the moment, it seemed that everyone except Ethan, who was also an alien, had been left far behind by Goku.
"Fifty times gravity..."
After Goku desperately completed one hundred times gravity training, his base power level was around ninety thousand. Using the Kaio-ken, he could unleash a power level of one hundred eighty thousand, and if he pushed himself further, he could keep increasing it exponentially from that ninety-thousand base.
However, the current Goku had not learned explosive techniques like the Kaio-ken, so that point could be ignored.
Moreover, Goku's training at that time had been extremely rushed, and he had not had enough time to train properly. He had only reached that number by relying on the special physique of a Saiyan.
"Perhaps the reason Goku's power level skyrocketed later was because the training during that period greatly increased his potential, but he did not have time to fully tap all of it."
In other words, if he truly completed one hundred times gravity training, his power level definitely would not stop at around one hundred thousand. If he had more time to draw out that potential, reaching several hundred thousand should be very easy.
"No!"
Ethan remembered that Vegeta had also undergone gravity training. With plenty of time, Vegeta directly achieved Super Saiyan, and his power level surpassed Goku's when Goku had become a Super Saiyan on Namek. It was hard to judge exactly what Goku's actual power level had reached by the time he fought the Androids because of his heart disease.
"In short, once gravity training is completed, raising the power level to several hundred thousand should be very stable."
A power level of several hundred thousand would be enough to instantly kill all enemies in the battles that might break out a few years later, except for Frieza.
Frieza at full power had a power level exceeding one hundred million. A power level of several hundred thousand could not even defeat his first form.
"Should I keep upgrading the gravity room?"
Carefully recalling the original plot, Goku's later training method was still the same simple and brutal weighted training, except the weights had become ridiculously heavy, measured in tons. That seemed to imply that as long as the gravity room could be built to higher multipliers, it could keep being used indefinitely.
"This is the only way..."
Ethan did not pursue explosive techniques like the Kaio-ken or transformations like Super Saiyan. He preferred to raise his base power level, feeling that this was the correct path.
In his eyes, both the Kaio-ken and the Super Saiyan transformation were techniques that increased "output power." Although they were powerful, they also increased the burden on the body and reduced stamina, as shown by the fact that Super Saiyan 3 could only be maintained for a very short time.
"Although I don't really like this kind of technique, if I can't raise my power level to one hundred million in a short period of time, then I'll have to study techniques like the Kaio-ken."
Otherwise, Frieza could only die by Goku's hand. Ethan did not care who got the kill, but before someone took the kill, he had to defeat Frieza first.
"I originally thought this mission would not be challenging at all, but now it seems the difficulty is not small."
Ethan suddenly realized that he had not been working hard enough and that he should train desperately like Goku. So he quickly made a decision: strive to complete one hundred times gravity training within a month!
