Son Goku's expression returned to normal when he heard that.
After all, he knew Kami was not wrong. Right now, the only thing that could help them was that place.
And Kami knew why Son Goku reacted like this the moment he heard "Hyperbolic Time Chamber."
Because after Son Goku defeated the old Piccolo, he had once gone inside at Kami's suggestion, but he had lasted less than an hour before running out. [PS:1]
That time was the first time Kami had ever seen Son Goku look so flustered and panicked.
After all, even though Son Goku was a Saiyan with an incomparably powerful physical potential, the Hyperbolic Time Chamber did not merely torment the body; it tormented the mind as well.
Training alone in an endlessly empty place, with no one to speak to at all—anyone who knew about it could understand just how unbearable that state was.
"You know what kind of place that is, right?" Son Goku turned to Son Gohan and asked.
"I know," Son Gohan replied.
"If it were before, I wouldn't agree to let you go in, but the current you can do it if I'm with you," Son Goku said with a nod.
"No, Father." Son Gohan shook his head and said, "I'm planning to go in alone."
"What!?" Son Goku was shocked again.
"I know what you're thinking, but right now I want to go in by myself. First, it can temper my mind. Otherwise, even if my strength improves in the future, I'll still be limited," Son Gohan explained.
First of all, Son Gohan knew that in the early Saiyan Saga of Dragon Ball Z, he was not the protagonist, and no matter how strong he became, it was impossible for him to surpass Son Goku.
As long as Son Goku entered the Hyperbolic Time Chamber, then Raditz would not really amount to much.
First, according to Son Gohan's memories from his previous life, Son Goku's combat power at this time was probably around 300 to 400, and Piccolo was also at the same level.
Raditz was roughly around 1500, but that was under the circumstance that Son Goku encountered Raditz out of nowhere. If Son Goku trained in the Hyperbolic Time Chamber, there was no need to worry at all.
No matter how poor the result was, after training, Son Goku could still raise his combat power above 10,000. Beating Raditz into the ground would not be a problem at all.
One had to know that when gathering and firing a Kamehameha, Son Goku's combat power would also briefly erupt. With that alone, this part was already secure.
Son Gohan, without having trained, also had an instant burst of combat power around 1300 when he was furious to the extreme.
So Son Gohan could judge that after drinking the Super God Water and then entering the Hyperbolic Time Chamber, no matter how bad things got, his combat power could not possibly be lower than 6000.
Therefore, what he needed now was to raise his mental realm. That way, once Raditz was defeated, he could go with Son Goku to train at King Kai's place, and everything would be perfect.
After training in the Hyperbolic Time Chamber, the ten-times gravity on King Kai's Planet would not be a problem. The most important thing was the technique King Kai had created.
This was an overpowered cheat tool in Dragon Balls that stood alongside the Senzu Bean and was called one of the three great BUGs—Kaioken!
It was a terrifying amplification technique that Son Goku could still use even after reaching Super Saiyan God Super Saiyan Blue.
Son Gohan had to learn this technique. There was absolutely no room for argument!
That way, before heading to Namek and receiving the Grand Elder's potential unlock, Son Gohan could greatly increase his own potential.
As for Vegeta, that combat power of less than 20,000 would be a piece of cake for Son Goku and Son Gohan after their double training.
Of course, Vegeta's combat power after using the Great Ape cheat could reach as high as 180,000. That was indeed a little tricky.
But when the time came, with him, Son Goku, and Piccolo joining forces, there would be no need to worry about that at all.
At worst, he could use his trump-card killer move and have Piccolo and Kami fuse ahead of time. Defeating Great Ape Tragic Vegeta would not be a problem either.
In this way, under the arrangements Son Gohan had already planned out, all the problems before heading to Namek would already be solved.
You say Piccolo might turn around and kill Son Goku and Son Gohan?
What kind of joke was that? They were all fans of Dragon Balls—did that even need to be asked? Of course, as for the possibility of this happening, Son Gohan had already prepared a trump card too.
That was, if Piccolo really did betray them, then Son Gohan would transform into a Great Ape!
Tragic Vegeta had once said that on Planet Vegeta, only a super-elite warrior like him could control his reason after transforming into a Great Ape.
This was why Son Gohan wanted to cultivate his mental realm right now.
In his view, Saiyans losing control after transforming into Great Apes was nothing more than their mental realm being polluted by massive slaughter amid the Saiyans' warlike, ceaseless fighting, making them prone to losing control after becoming Great Apes.
As long as his mental realm reached that level, controlling his reason after transforming into a Great Ape would not be difficult. Son Gohan still had that much confidence.
You ask what if he could not control it?
Son Gohan had also left himself a fallback. That was, both Son Goku and Master Roshi knew that in Great Ape form, as long as the tail was cut off, one could return to their original human form.
All of this had long since been included in Son Gohan's calculations.
In this world where danger could descend at any time, Son Gohan had to seize every detail and possibility, doing his best to create trump cards for himself.
"Are you sure you can train alone in that space?" Son Goku asked in an extremely doubtful tone.
After all, no matter how mature Son Gohan had acted before, Son Goku still needed to worry about this.
"Dad, don't worry. If I can't hold on, I'll come out early. After all, as long as the time limit isn't reached, I can still go in again," Son Gohan said with a confident expression.
"That's true," Son Goku said with a nod.
For the two of them, the Hyperbolic Time Chamber would not pose a fatal threat, so they could indeed use this opportunity to see just how great Son Gohan's potential really was.
"In that case, you can go in alone," Son Goku said, convinced by Son Gohan.
"Dad, I suggest you go look for Piccolo. If he's willing to go in and train with you, your strength will improve very quickly, and you'll also gain a powerful helper," Son Gohan suddenly suggested.
Son Goku and the deity beside him were both taken aback when they heard this. After listening, the former looked tempted, while the latter's expression turned grave.
Son Gohan knew what Kami was worried about, so he turned and said, "Kami, if you're worried that Piccolo will become like his father, then you don't need to be."
"I can say for certain that right now, Piccolo only wants to defeat my father. And after fighting those evil aliens, even if he wanted to, there's no way he could keep his mind on a little place like Earth anymore."
Son Gohan folded his arms and looked at Kami, his face and eyes filled with a kind of confidence.
"And if we really can't beat them, then he and you are our final trump card for protecting Earth, aren't you, Kami?"
Son Gohan looked at Kami with blazing eyes.
