After dropping Yamcha and Oolong off where they wanted to go, Goku returned to West City with Bulma.
Bulma's home was right in the center of West City, and Goku couldn't help marveling at how much space it occupied downtown.
Goku had just followed Bulma inside when Mrs. Brief came over to greet them.
"Bulma, you're finally back! Did you have fun out there? Hmm, who's this handsome young man?"
Mrs. Brief had wanted to chat with Bulma about everyday matters, but when she saw Goku, she asked Bulma about him instead.
"He's a friend I met on my trip. His name's Son Goku, and he came back with me to teach me martial arts."
"A friend? He's teaching you martial arts?"
"Yeah, he promised he would."
"Hello, Bulma's mom. My name is Son Goku."
"Hello, Goku. Just call me Mrs. Brief."
Mrs. Brief had more to say, but when she saw that Goku and Bulma were still standing by the door, she ushered them inside.
When they reached the living room, they saw Dr. Brief.
"Dad."
Hearing Bulma call him, Dr. Brief turned toward them. He spotted Goku at once and looked at Bulma and her mother in puzzlement.
"Hello, Bulma's dad. I'm Bulma's friend. My name is Son Goku," Goku introduced himself.
"Hello, Goku. Just call me Dr. Brief. Come, sit down. Would you like some tea?"
Dr. Brief poured tea from the pot into a cup and invited Goku to sit down and drink.
After sitting down, Goku picked up the cup and took a sip. In an instant, the aroma of tea filled his mouth.
"Excellent tea!"
Unlike most young people, Goku had enjoyed drinking tea before transmigrating.
"Hmm? I didn't expect someone so young to know tea. Not many young people do, you know. This was brewed from the finest tea leaves on Earth," Dr. Brief remarked.
Goku scratched his head, feeling a little embarrassed.
"All right, Dad, I'll take Goku to pick a room first," Bulma said impatiently, seeing that her father seemed ready to strike up a conversation with him.
"Pick a room?" ×2
"Yeah, Goku's staying at our house. He still has to teach me martial arts!"
"Come on, Goku."
"Oh, all right. Dr. Brief, Mrs. Brief, I'll take my leave."
After saying goodbye, Goku left with Bulma, leaving the couple thoroughly bewildered.
The two exchanged a glance and nodded.
"Goku, you can stay in this room from now on."
Goku looked at the room, which had its own balcony and was at least fifty square meters, and nodded.
"Okay."
"So when are you going to teach me to train?" Bulma was clearly growing impatient.
"Tomorrow. I still need to try out the gravity room today."
"You can put the gravity room in that empty space."
With that, Bulma pointed to a huge open area.
Goku looked in the direction she pointed. It was beside a huge swimming pool, with a large landscaped strip between them.
"Okay."
"Go on and get busy. I'll call you when it's time to eat." Bulma knew Goku couldn't wait to try the gravity room.
Goku nodded and flew toward the huge open area.
When Bulma reached the first floor, she saw that her parents seemed to be waiting for her.
"Bulma, come here a moment."
"Oh, okay?"
"You go away. I want a proper chat with my daughter."
After Bulma came over to them, Mrs. Brief sent Dr. Brief away.
"Bulma, what's going on with that boy Goku? You actually like younger boys?"
Bulma bristled the moment she heard that.
"What do you mean, what's going on? He's just my friend! Besides, he's only twelve. How could I?"
"A friend? You brought a friend home and let him live here? Yes, he's twelve now, but that doesn't mean he won't grow up. Don't think I can't tell-he'll definitely be handsome when he's older. If you don't make a move, I will!" Seeing Bulma still refusing to admit it, Mrs. Brief couldn't resist teasing her.
"Hmph! I'm not talking to you! Think whatever you want! You always have an answer for everything I say anyway!"
With that, Bulma stormed off.
She went to her room and pulled the covers over her head.
Yes, she didn't know why she had brought Goku home either.
After setting up the gravity room, Goku went inside.
Back then, Goku had been able to withstand ten times gravity with a battle power of over four hundred. With his own battle power just over three hundred, five times gravity wouldn't be a problem.
When Goku switched on five times gravity, the sudden pressure made him stagger, and he nearly fell to the floor.
"Whew, no wonder they say a gravity room is a must-have when you transmigrate into Dragon Ball. You have to experience it to know just how much the pressure of gravity on every cell helps raise your battle power," Goku said as he trained.
Evening.
"Goku, come out and eat."
"Okay."
At dinner, the Briefs were especially warm toward Goku.
They thought Goku was bound to become their son-in-law someday, so how could they not be warm toward him?
As for Goku's family background, did it matter? No matter how good it was, could his family be richer or more powerful than theirs?
Goku's appetite did surprise them a little, but they didn't think much of it. Instead, they thought eating a lot was a good thing. Eating a lot meant good stamina, so they wouldn't have to worry about their daughter's future happiness.
The Briefs' enthusiasm left Goku a little overwhelmed.
After dinner, Goku chatted with Bulma.
"Bulma, why are your parents so nice to me? It's making me a little embarrassed."
"H-how would I know? If they're being nice to you, just enjoy it."
Bulma rolled her eyes at Goku. Between how enthusiastic her parents were and her earlier conversation with them, she had actually guessed a little, but she certainly couldn't tell Goku.
"Goku, school starts in a little over twenty days. Can I master that flying martial art of yours before then?"
"I don't know. It depends entirely on your talent. If you're talented, you can. If not, you can't."
"Then how many days did it take you to learn?"
Goku felt like laughing at Bulma's question. Wasn't she just asking him to show off?
"I learned it myself. How many days? I sensed Ki almost instantly, then figured it out in less than half a day, I think."
"You!"
Bulma raised her fist and punched Goku hard, but he didn't react at all. Instead, her hand hurt a little, and she began to sulk.
"Hmph! I'm done talking to you. I'm going to bed."
Bulma turned and left. After watching her go, Goku returned to his own room.
Early the next morning.
Bulma sought Goku out early.
"Goku, you promised to teach me to train today!"
"All right, all right, I know," Goku said with a wry smile.
In the yoga room, Goku sat down cross-legged with Bulma.
"To learn the Flight Technique, the first step is to sense the Ki inside your body."
"The Ki inside my body?" Bulma was a little puzzled.
"Yes. Everything has Ki inside it, but the vast majority can't sense or control it. The stronger a person is, the easier it is to sense their own Ki."
"Then how do I sense it?"
"That depends on each person's talent. Calm down and clear your mind. You might not understand if I put it that way, so give me your hand."
Following Goku's instructions, Bulma obediently held out her right hand to him.
"I'm going to move a tiny strand of Ki into your body and circulate it. Try to sense it."
And so, time passed minute by minute. Nearly half a day went by, and it wasn't until mealtime that Bulma finally managed to sense the Ki inside her. The effort nearly exhausted Goku to death.
He had to control that tiny strand of Ki as it flowed through Bulma's body at every moment while making sure it didn't harm her. Anyone who tried it would know how tiring it was.
Seeing Goku's pale face and how close he was to exhaustion, Bulma felt a little embarrassed.
"Sorry, Goku."
"I-it's okay. Let's eat. I should feel much better after a meal."
In the end, Goku only made it to the dining table with Bulma supporting him.
Seeing Goku like that, the Briefs looked at Bulma in surprise.
Goku was still so young. It couldn't be!
"Bulma, what happened to Goku?"
"Whatever it is, it's not what you're thinking."
Bulma knew her parents weren't thinking anything decent and answered irritably.
That afternoon, after Goku had caught his breath, Bulma ruthlessly dragged him away again.
"Bulma, for now you just need to meditate and exercise, and keep strengthening the Ki inside your body."
With that, Goku hurriedly flew away.
Ten days later.
"Woo-hoo! I'm a genius! I learned to fly in ten days!"
Bulma couldn't help boasting as she flew through the sky. Beside her, the corner of Goku's mouth twitched when he heard her.
If he hadn't used his Ki to guide Bulma on the first day, she might not even have sensed Ki before school started.
