Master Roshi saw that Gaino and Laiya held no hostility toward him, so he relaxed his guard.
Master Roshi turned to Gaino and said, "You said you're Saiyans from outer space. What kind of race are Saiyans? I've never heard of them. We Earthlings have always lived on this planet and have never been to space. How did you find out about Earth?"
Gaino said, "That's a secret." (Am I supposed to tell you I'm a transmigrator who knows the Dragon Ball plot?) "We mean no harm by coming to Earth, so please don't be so tense, Master Roshi."
At the Lookout, the Guardian heard Gaino's words and asked Popo, "Popo, do you know about outer space? And what about Saiyans?"
"I don't, Guardian. I'm only your servant. I've always stayed on Earth and never left it," Popo replied.
"It seems these two Saiyans mean no harm to Earth. If they wanted to destroy this planet, there'd be nothing we could do. I can feel an immense amount of ki from them both."
Popo could feel it too. He spoke woodenly.
"You said you came to Earth to get better at controlling ki, right?" Master Roshi asked.
"That's right. We came to Earth from far away because we heard that Earthlings focus on ki in their training. A master like you, Master Roshi, has already achieved perfect control over it." Gaino showered Master Roshi with praise.
As Master Roshi listened to Gaino's compliments, his mustache curled upward. He hadn't expected to be so famous even out in space.
"Of course! Who in the universe hasn't heard of Master Roshi?"
Laiya looked at her big brother, Gaino, her eyes wide. Her big brother could spin one tall tale after another without even blushing!
Gaino seemed to notice Laiya's stare. He coughed, then said to Master Roshi, "Master Roshi, please teach us how to train our ki!"
"All right. Since you've come all this way to Earth, I can't send you back empty-handed. And don't call me Master Roshi anymore. My name is Mutaito—just call me Master Mutaito!"
"All right, Master Mutaito. Let's start training our ki!"
Laiya called him Master Mutaito, then said, "Big brother Gaino, is this old man really up to it? Can he actually teach us? His battle power isn't even as high as ours!"
"Laiya, don't be rude. You can't judge someone by their battle power. Master Mutaito is a martial arts master, more than qualified to teach us how to train our ki. Watch what you say."
Gaino cupped his hands toward Mutaito. "Master Mutaito, my sister doesn't know her manners. Please forgive her."
Mutaito laughed. "It's all right, it's all right. Your sister certainly speaks her mind!"
Mutaito turned to Laiya. "That's right, young lady. You and your brother have far more ki in your bodies than I do, but your control over it is indeed very crude."
Laiya scoffed. "You talk a good game. Then show us what you can do! Let me tell you, old man, we Saiyans only respect the strong. Words alone won't convince us."
"Then how would you like me to prove it, young lady?" Mutaito asked.
"How about a beam clash? You said our control over ki is too crude, right? Let's see whose beam is stronger. If you beat me, I'll believe you're the real deal, old man. What do you say?"
"Laiya, don't be reckless. Your ki is so powerful. What if you hurt Master Mutaito?"
"It's fine," Master Mutaito said. "It's just a beam clash. My ki may not be as plentiful as yours, but I'm confident in my control over it. Come on, young lady."
Laiya held out her palm, and a Ki Blast appeared in it. Across from her, Master Mutaito clasped his hands together and unleashed his special move: the Kamehameha.
The two energy waves collided, and the sea around Master Roshi's island exploded. As the clash continued, Laiya gradually fell behind.
Master Mutaito unleashed another blast, and the Kamehameha slammed into Laiya, sending her flying.
Laiya plunged into the sea. Gaino hurried toward the spot where she had fallen. Master Mutaito said, "Don't worry. The young lady's fine. I was careful not to hurt her."
Sure enough, a moment later, a figure shot out of the water. Laiya went straight to Master Mutaito, bowed slightly, and said, "Old man, I keep my word. You won. I'm convinced."
Mutaito nodded.
"All right, then let's begin training. Sit down here, both of you. Use your minds to sense the ki inside you, then let it flow slowly through your bodies. That way, when you fight, you'll be able to draw on your ki, and you'll use up your stamina more slowly."
Gaino and Laiya began training with Master Roshi. A month passed.
One day, two figures darted across Master Roshi's island, and the sounds of battle rang out. Laiya and Gaino were sparring. After more than a month of training, they had mastered the use of the ki in their bodies.
High above the island, Master Mutaito watched Laiya and Gaino spar. The thud of their blows rang out now and then, and the sea churned. Suddenly, a figure shot up from the water, nearly crashing into Master Roshi.
It was Laiya. Gaino had knocked her flying, and he came over to her. Laiya said, "Big brother Gaino, I'm done. You win every time we spar. This is no fun, no fun at all."
Gaino said, "Laiya, you still need to keep working hard." After a month of training, Gaino's ki had risen to 100,000, while Laiya's had grown even faster, from 3,000 to 90,000. Her battle power had increased so much that Gaino was jealous.
Gaino was always saying, "Laiya, how did your battle power grow so quickly? No wonder you're an elite warrior."
"Haha, of course! I feel like if I train hard a little longer, I'll be able to surpass you, big brother Gaino."
Gaino said, "Then you'd better keep working hard."
"Mm, I will, big brother Gaino," Laiya replied.
Just then, Master Mutaito said to Gaino, "I've never seen talents like you two. You've mastered ki to this degree in just one month. I'm jealous of your talent!"
Laiya said, "Old man, that's not something you can envy. We Saiyans keep growing stronger through battle."
"Growing stronger through battle? Your race really was born to fight."
"You're right. The Saiyans are known throughout the universe as a warrior race."
"No wonder. I have nothing more to teach you. You can leave now."
Gaino said, "Master Mutaito, thank you for your guidance. Until we meet again."
With that, Gaino flew off.
"Old man, I'm off too. Goodbye." Laiya followed Gaino, disappearing from Mutaito's sight.
