A completely different sensation crashed over him.
If ten times gravity was like carrying a heavy pack, then twenty times gravity felt like the entire sky had collapsed, crashing down hard on every bone and every strand of muscle!
Son Mirai could barely breathe, and even moving was becoming difficult.
"I was born on Planet Vegeta. I should be able to move freely under ten times gravity. This is only twenty times gravity, so why is it so hard..."
Son Mirai wiped the sweat from his forehead.
"Never mind. I'll get used to it first. I don't have any Senzu Beans, so I can't afford to get hurt..."
Under twenty times gravity, Son Mirai began his basic training again.
Goku had Senzu Beans, which was how he managed to adapt from ten times gravity to a hundred times in seven days.
But that was only possible because he had spent a year adapting to ten times gravity on King Kai's Planet, and had recovered from severe injuries during the battle with Vegeta.
At this point, Son Mirai's foundation was nowhere near good enough. Under this kind of gravity, he couldn't move freely at all.
He stopped aiming for smooth, fast movements and focused instead on completing simple basic exercises.
Under such intense gravity, every time he raised an arm, it felt as if he were struggling to push away a mountain. Every time he bent his knees, his thighs trembled.
By the time he finished a simple set of basic exercises, Son Mirai was completely exhausted. He collapsed onto the floor and panted heavily.
"Whew... whew... whew..."
"This kind of gravity is dangerous. I could die suddenly if I'm not careful. I need to be cautious."
At noon, Son Mirai left the Gravity Chamber.
The intense training that morning had taken too much out of him. He felt so hungry that his stomach was practically touching his back.
Fortunately, Bulma had come home from school, and it was time for lunch.
This time, Son Mirai didn't hold back. He wolfed down his food.
Watching him devour his meal, with plates piled up beside him higher than he was tall, Bulma and her family stared in astonishment.
Mrs. Brief covered her mouth and giggled. "Hehehe, young people sure have healthy appetites!
"Don't worry. I'll have the kitchen make you some more..."
Son Mirai thanked her as he ate. "Thank you..."
Bulma exclaimed, "How did you get so hungry? It's terrifying!"
"Yeah, you'd think he'd never eaten before!" Dr. Brief chimed in.
As Son Mirai ate, he said, "I should go to Korin Tower when I have time and get some Senzu Beans."
"Senzu Beans? What are those?" Bulma asked curiously.
Mrs. Brief smiled. "Are they beans that immortals eat?"
Son Mirai thought about it, then nodded. "More or less. You only need to eat one, and you won't feel hungry for ten days."
Bulma rested her chin in her hands and asked with some interest, "Really? Do they taste good?"
Son Mirai swallowed another chicken drumstick in one bite. "I don't know. I've never eaten one,
"but they probably taste like regular beans. They're just really effective."
"I see!"
Bulma instantly lost interest in Senzu Beans.
After all, she thought enjoying good food was one of life's pleasures. Going ten days without eating would be so boring.
He didn't want Senzu Beans to replenish his strength or exploit a loophole.
Son Mirai had suffered plenty of setbacks because of his recklessness, and he didn't want to die in there because of a mistake.
Even if he died, Bulma could use the Dragon Balls to bring him back, but it would be so embarrassing.
With Senzu Beans, he'd be completely safe.
He'd go there after the World Martial Arts Tournament.
Thinking of the tournament, Son Mirai realized he should tell Bulma about it. He'd almost forgotten.
"By the way, Bulma. The World Martial Arts Tournament is being held in a month. Master Roshi is taking us to compete..."
Bulma asked, "Is that the World Martial Arts Tournament that's held every few years?"
"Yeah. It's held every five years now, but I think they'll reduce that to every three years later!"
Bulma said, "Got it. Our school will be on break in a month, too. I'll come watch."
"Great. I knew you'd come. You can go there on your own. I'm flying there with Master Roshi and the others."
Bulma didn't want to ride Son Mirai's Log-Riding Flight, either. She didn't object and simply nodded. "Okay. Remind me when the time comes, and I'll go on my own!"
Before long, the table was covered with empty plates. Fortunately, Son Mirai had finally eaten his fill.
"Whew, I'm stuffed..."
Son Mirai rubbed his stomach and leaned back in his chair, relaxing.
Dr. Brief and his wife had already left.
Bulma smiled. "You eat so much. Can you afford your living expenses? Do you need me to give you more?"
Son Mirai shook his head. "No. I don't get this tired at Master Roshi's place, so I don't eat this much every day."
Bulma covered her mouth and giggled. "It's fine. Eat as much as you want. I can afford to feed you even if you eat this much every day..."
Two days of rest and relaxation came to an end.
Son Mirai spent the days in the Gravity Chamber, ate lunch with Bulma, and kept her company in the evenings.
After two days, he felt that he'd improved, but not by much.
However, Son Mirai didn't pay much attention to the small increase in his stats.
Training was like losing weight: it was a long journey. A couple of days of intense effort now and then wouldn't lead to any unbelievable improvement.
Unless he exploited a Saiyan loophole.
But depleting his potential like that wouldn't mean much for him right now.
What mattered most was keeping a level head and sticking to steady, day-by-day training.
After returning to Kame House, Son Mirai continued training as usual.
Although Master Roshi no longer trained them, the three of them didn't slack off.
After all, the World Martial Arts Tournament was coming up, and they all wanted to do well.
So they added suitable weights again and continued their previous basic training.
In their spare time, the three of them also sparred with each other.
In the blink of an eye, time passed, and the day of the tournament arrived.
Master Roshi wore a suit and was dressed smartly.
"All right, our training is on hold for now. The World Martial Arts Tournament is tomorrow, so we're leaving for South City!"
"We're going tomorrow? Great!"
Son Goku was thrilled. He could finally fight some strong opponents.
Master Roshi nodded. "That's right. You can take off your Turtle Shells now."
Krillin exclaimed in delight, "Great! I thought we'd have to wear them to the tournament. That would've been so embarrassing."
Soon, all three of them took off their Turtle Shells.
Krillin stretched and said, "It feels so much lighter without the Turtle Shell. It's like there's no gravity!"
Goku stretched, too, seemingly getting used to his unburdened body again.
Master Roshi smiled. "All right, try jumping!"
Goku gave a light hop and suddenly soared more than ten meters into the air, startling Krillin.
"Whoa, that's high!"
"I'll try, too!"
Krillin jumped as well.
In an instant, he rose almost as high as Goku.
The two of them looked at each other in midair.
"Hahahaha, this is amazing!"
"I can jump this high, too!"
Krillin couldn't help laughing.
The next second, Son Mirai launched himself into the air and shot past the two of them.
Goku and Krillin were both startled, then looked up in unison.
Son Mirai had jumped more than twice as high as they had.
"Whoa, Son Mirai, you're incredible..."
Seeing Son Mirai almost reach the clouds, Master Roshi's pupils suddenly shrank.
"Uh-oh. He seems to be stronger than I expected. What if my student beats me?"
Just then, the blond-haired Launch walked over.
"What are you all dawdling around for? If we don't leave now, we'll miss the plane to South City!"
