"Yes, you should know by now how to use it, right?" Fein smiled.
Hearing his question, Roger shook his head bitterly, "Not really. This thing you gave me seems a little complicated to use. There's a lot of unfamiliar things even with the instruction manual."
"Well, Let me teach you then..." Fein walked beside Roger and took out another phone and started to explain the functions of the mobile phone attentively.
Just like how he taught Kassandra, he also patiently demonstrated each of the applications use to the point that even elementary students on Earth would understand.
Roger just kept nodding as he listened attentively. His eyes shined over time as he became more familiar with the use of the phone.
'This thing would revolutionize the aspect of communication in the future!' Roger's eyes turned serious.
As a businessman, he knew the prospects of the thing in his hand in the market. With this, communication with people would become easier. Trades and countless things would improve, and Roger can't fathom just how much change the mobile phone in his hand would bring. But he was certain of one thing: the world would develop at a pace that was faster than before!
He couldn't help but take a deep breath when he thought of this. Now, he just wants to hug the thigh of the person in front of him!
Fein felt an inexplicable shudder. 'Damn, is someone cursing me on their mind right now?' He looked left and right but he didn't find anything. 'Must be my imagination...' He shook his head and decided not to think too much.
"So I would just contact you here?" Roger tapped one of the applications.
It looks like a book that has a drawing of a person with a question mark design. The mobile phone blinked, and he saw an 11-digit number saved on the list. When he clicked the number, there's two fill in the blanks of information appeared, namely - Name and address.
Fein looked at the screen of the mobile phone and says, "Yeah... That's my mobile phone number that I saved on that device in advance. You just need to click the white logo and it would automatically call my device."
Roger nodded. He still had confidence in his comprehension speed. So he just clicked the blank information and typed the other party's name 'Fein Bonifacio'.
"What is your address?" Roger turned his head at Fein.
"Well, you can leave that for now. It doesn't matter, anyway."
"Okay..." Roger nodded, and he tapped the white button.
*Beep!* *Beep!* *Beep!*
Fein heard the ringtone of his phone in his ears as he felt the black mobile phone in his hands vibrate.
He looked at the name of the caller and turned his head at Roger, who was staring with curiosity at his phone.
"That's what happens?" He asked.
"Yeah," Fein answered as he saw a green button on the left screen and a red button on his right screen.
If Earth people saw this, they would know that once you swipe the green button, it would answer the caller, while the red button is for the decline.
He swiped the green button on the left without hesitation. "Hello," He raised the phone to his ears.
Roger became stunned when he also heard Fein's voice on the device that he holds. He also raised the speaker of the phone to his ears.
"Bastard talk, or I will find you and I will kill you!"
Roger looked at the smiling Fein with doubt and says, "Fuck you!"
*Fuck you!*
Roger only heard his voice echoed at Fein's mobile phone. 'Damn! it's really working!'
"See?" Fein lifted the corner of his lips as he gazed at the astonished Roger.
"It really is... Are you also the one invented this?" Roger stared at Fein as he held his breath.
"Yeah, see how smart am I?" Fein entered his flexing mode instantly when he saw the opportunity.
"..." Roger didn't know what to say, and he just stared at Fein with a numb expression. He just experience a lot of things today, and each of them is enough to subvert his cognition.
'I'm getting better at this,' Fein thought with a smirked in his face. 'What about the time when I invent a nuclear bomb? Just what would their reaction be??' but suddenly he shook his head to throw this idea at the back of his mind. 'It's better not to invent that heinous thing. Or this crazy would become crazier.' he sighed.
He knew just how powerful a nuclear bomb was... A nuclear bomb was enough to severely injure an A-rank or even S-rank! Of course, that's only possible if the target S-rank didn't resist, but if an S-rank is prepared. He could still get away with easily.
Fein waved his hand at the dazed Roger and asked loudly, "Hey buddy, are you okay? Why do you look like someone who lost their soul?"
"I'm okay... It's just feels surreal to me that's all. You're kinda awesome, I must say." Roger felt emotional...
This is the first time he saw a human that was as talented as Fein. No, this might even be the last time!
'It's as if God took his time when he created this bastard.' Roger sighed, then he placed his hand inside his pocked. He rummaged it for a few seconds before he finally felt the thing he wants. A black-red card appeared on his hand and he gave it to Fein.
"What's this?" Fein inquired as he scanned the card's appearance.
The card has the same as the design as the one in Roger's shop. It's also has a huge VIP letters etched on top of it with a five star drawing.
"Well, it would be embarrassing if I'm the only to receive something. That's a VIP card in my shop." Roger smiled. "Every time you buy at any branch of my shop, they would give you a fifty percent discount. And they would also give you the highest quality of service."
"Thanks, this is a good thing." Fein smiled, and he stored the VIP Card to his system's storage.
"Since we're done here, Let's go." Roger jumped with full strength and went through the hole in the sky where they entered earlier.
