Seeing this, Master Roshi's jaw dropped, and he was too shocked to speak.
"When did you become this strong?" Master Roshi asked in astonishment.
Hearing this, Ziye chuckled and explained indifferently, "Perhaps the devilish training over the past half-month has improved my strength!"
"Haha!"
Hearing this, Master Roshi naturally didn't believe it. After an awkward laugh, he turned around and scolded Goku and Krillin, "Did you see that? It's because you two are lazy and don't train that you can't even push such a small rock!"
Upon hearing this, Krillin and Goku couldn't help but lower their heads in shame. Seeing that this method worked, Master Roshi finally breathed a sigh of relief.
"Do you really want to learn martial arts?" Master Roshi asked in a serious tone.
"Mm-hmm."
The two nodded in unison.
"Good. As long as you can meet my requirements in the upcoming training, I will teach you!"
"Furthermore, I will take you to participate in the quinquennial World Martial Arts Tournament."
Master Roshi said with a solemn expression.
"World Martial Arts Tournament? What is that?" Goku asked curiously.
"It is the place all martial artists yearn for. Every expert in the world will attend, and I hope you can achieve good results there!"
Hearing this, Goku and Krillin jumped up in excitement.
"Alright, the next phase of training is devilish weighted training."
As he spoke, Master Roshi took out three purple turtle shells of different sizes from behind him and continued, "These two shells weigh twenty kilograms, and this one weighs forty kilograms. From now on, you must wear them while eating, sleeping, and training!"
"Do you understand?"
"Understood!"
The three of them nodded quickly in response.
Afterward, the three stepped forward and strapped on the shells. Ziye naturally chose the heaviest one, and in the days that followed, they resumed their routine training life.
Five months later.
"Grandpa!"
Goku rushed into Kame House with a twenty-kilogram shell on his back!
"What is it, Goku..."
Before Master Roshi could finish his question, Goku pulled him and ran outside!
"Goku, slow down. What happened?"
Soon, Master Roshi was brought by Goku to the giant rock, where Krillin and Ziye were already waiting.
"Grandpa, we can finally push this rock!" Goku said excitedly.
"How is that possible..."
Master Roshi shook his head with a smile, but the scene that followed completely shocked him. He saw Goku exert all his strength, and the rock actually shifted several meters.
"My turn! I might not push it as far as Goku!"
With that, Krillin stepped forward and used all his strength. The next second, the rock moved several meters again.
"I don't need to demonstrate, do I?"
Ziye asked with a smile.
"Old man, can you teach us martial arts now?" Goku asked sincerely.
Hearing this, Master Roshi couldn't help but feel a bit troubled. After some thought, he answered truthfully:
"This..."
"Actually, I don't have any specific martial arts techniques. The essence of the Turtle School martial arts has already been integrated into your daily training!"
"Perhaps you haven't noticed it yourselves, but every part of your bodies has been tempered, and your strength and speed have undergone a qualitative leap!"
"I have nothing left to teach you now!" Master Roshi shook his head and said in a flat tone.
"Old man, but without martial arts techniques, how are we supposed to defeat others?" Goku asked in confusion.
"The most important thing in martial arts is not defeating others, but surpassing yourself!" Master Roshi said meaningfully.
"The World Martial Arts Tournament is one month away. You can continue your training as usual, but the weight of the turtle shells will be doubled!"
"Yes!"
Immediately after, the three changed into their new gear and began their day-after-day devilish training once more.
Time passed quickly, and the day of the World Martial Arts Tournament quietly arrived!
"Tomorrow is the start of the tournament. You may take off the shells you've been wearing," Master Roshi said to them.
"That's great!"
"I was worried I'd be laughed at by the other contestants for wearing this thing!"
Hearing this, the three of them happily shed the weights from their bodies, and a sudden feeling of lightness washed over them.
"Wow, my body feels so light!" Goku said excitedly.
"Try jumping with all your might."
Hearing this, the three of them quickly leaped, and in the next second, they soared dozens of meters into the air!
"Haha, alright, let's head out!" Master Roshi chuckled and said.
"Launch, I'll leave the house to you!"
Hearing this, Launch made an OK gesture and said with a smile, "No problem!"
"Oh, Ziye, these are the new clothes I prepared for you all. You must do your best in the tournament!"
"Thank you."
After taking the clothes from Launch, the three of them followed Master Roshi and headed toward the World Martial Arts Tournament.
After leaving Kame Island, the group boarded a plane bound for the World Martial Arts Tournament. After flying for nearly half a day, they finally arrived at their destination.
"Wow, there are so many people here!"
"Indeed, it's certainly lively."
"Such a nostalgic feeling," Ziye said with a calm expression.
"You all wait here; I'm going to go register you!"
With that, Master Roshi headed toward the registration desk at the entrance of the World Martial Arts Tournament!
"Hey, Goku, Ziye, long time no see!" Suddenly, a handsome man with short hair walked over and greeted the two of them.
"Who are you?" Goku asked with a puzzled look.
"Are you... Yamcha?" Ziye said with a look of surprise.
"That's right!" Yamcha nodded with a smile.
"How did you end up like this? You changed your hairstyle so much I almost didn't recognize you!" Goku said in surprise.
"Haha! Bulma said long hair is too unfashionable in the city, so I cut it!" Yamcha rubbed his head and said with a smile.
"This is Krillin, who trained with us under Master Mutten!"
"And this is our friend, Yamcha." Ziye introduced the two to each other.
"So you're a top disciple of Master Mutten, a pleasure to meet you."
"I've heard about you from Ziye and Goku; I hear you're very strong."
The two then exchanged polite greetings.
"Ziye, Goku!"
At this moment, Bulma walked over with an ice cream, smiling alongside Oolong and Puar.
"Everyone, long time no see," Ziye said with a smile.
"Lo... long time no see!" Seeing Ziye, Bulma's cheeks turned bright red.
"Huh? Bulma, why is your face so red? Are you sick?" Goku asked with a confused look.
"She's just thinking about men!" Oolong licked his ice cream and said flatly.
