The Heroine Eavesdropped on My Voice Heart

What Qin Tian took out of his system inventory was a small square box that contained many small bottles filled with blue-colored liquid.

"What is that?" Rias stared at the small bottles in his hand curiously.

"Is it some kind of magic potion?" Grayfia was also curious.

She knew a lot about the magic potions that were usually sold in the underworld, but all those potions mostly had poison effects or magic regeneration effects. There are only a few types of potions in the underworld, and those are actually rarely used, except for magic regeneration potions which are usually often used during wars or long-term battles. The effect was also not good enough and only doubled the speed of magic regeneration on the devil's body, but it was better than nothing.

Everyone stared at the bottles in Qin Tian's hands curiously.

Qin Tian smiled and explained. "This is a dual experience potion. After you drink it, you'll gain 50 times the experience when you train, meaning your training effectiveness will increase 50 times after drinking this potion. The duration of this potion's effect is 1 day per one bottle."

"This... Isn't this too precious for us to use, Tian?" Rias felt bad about receiving something so precious like that for her and her peerage.

"Rias is right, this potion is too valuable, right?" Akeno also thought the same as Rias.

Grayfia had an serious expression after hearing the effects of the dual experience potion.

If news of this potion spread, wouldn't many supernatural beings in the underworld jump for joy with their eyes full of greed?

After all, the effect of a 50-fold increase in training effectiveness is quite tempting, it could shorten the time for someone to become stronger in a short period of time.

Before Rias' Rating Game against Riser started, she was certain that Rias and her peerage would experience a huge increase in skill and power in just a few days after drinking Qin Tian's dual experience potion.

Li Yan wondered where her little Tian got such items from? Even in the treasured Qin family treasury, there wasn't anything like that experience potion.

Was that potion also useful for increasing cultivation speed to 50 times?

"If you guys feel bad about receiving this potion for free, how about buying it?"

Qin Tian smiled wryly, for him this experience potion wasn't very valuable, he even had many similar things within his inventory that he had collected in the previous round.

That experience potion was just a drop from the items inside his inventory. So he didn't think much of it, even he didn't mind giving it away for free, especially if it was to help his girlfriend and friends.

"The Gremory family will pay for this experience potion. What do you want for payment, Tian-kun?"

Grayfia wanted to negotiate about the dual experience potion, she was sure the Gremory family was willing to pay top dollar, especially after knowing the potion's effects.

She didn't suspect that Qin Tian was lying about the potion's effects, after all there was no point in him lying to them for something like this.

"Let's think about payment later, I'll think about it first. Now let's start the training!"

Qin Tian said to everyone.

Grayfia nodded, she began instructing Rias and her peerage to drink the dual experience potion first before starting the training.

Then Grayfia began to train Rias and Akeno's magic control.

Li Yan brought Koneko to the other side where she could train her freely. She will teach this loli a good martial art for her.

As for Qin Tian? He looked at Yuuto with a smile and said. "Are you ready to accept my training Yuuto?"

"I'm ready Tian-senpai!"

Yuuto nodded with determination in his eyes.

"Then you will have to endure the headache you will experience while I am transferring my sword techniques directly into your brain."

"Yes?" Yuuto replied in confusion, it seemed that this training did not match what he thought.

What does it mean to transfer sword techniques directly into his brain?

For some reason he became nervous.

"Alright I'll start."

Qin Tian said as he reach out his hand.

"T-please be gentle with me Senpai." Yuuto said nervously.

Don't say such ambiguous sentences damn it!

People will misunderstand!

Qin Tian roared in his mind.

This young master is not interested in men, please calm down readers!

Don't get me wrong, all this nonsense is just a joke!

Without saying much more, she reach out her finger to Yuuto's forehead.

...

While Qin Tian was busy in the underworld.

In a fairly crowded cafe, there were two people who were currently sitting side by side.

The two people were beautiful girls, the people in the cafe even occasionally glanced towards their seats, as the two girls' appearances were very attractive.

"Maria, are you sure your plan will go well?" The beautiful red-haired girl asked the girl sitting next to her.

"Don't worry, Mio-sama. I've confirmed that the family consists of only the father and one son. I've hypnotized the father into believing that he just remarried and his wife had two daughters before marriage and those two daughters are us."

The girl called Maria said to the red-haired girl whom she called respectfully.

Her full name is Maria Naruse, she is a 15-year-old girl who looks like a loli. Her hair is long white with two small black ball-shaped ornaments and pink ribbons hanging on either side of her head.

Her appearance is more cute than pretty, especially with her black gothic loli dress with white lace that she is wearing.

Despite her human appearance, she is actually a succubus!

"So now we need to meet that father and daughter pair at a fast food restaurant, right?"

The red-haired girl named Mio asked Maria again.

Her full name was Mio Naruse, her last name was the same as Maria's, that was because the two of them were half-sisters. Mio was Maria's older sister, because she was 16 years old.

Mio's appearance was very beautiful, she had waist-length red colored hair and pink eyes. Her body was very developed for a 16-year-old girl, especially her large breasts.

And she's not fully human, she's a hybrid of human and demon.

Mio is the girl who a few days ago complained about wanting to watch the villain Qin Tian and protagonist Issei fight on a park bench while eating jelly.

She of course couldn't watch the fight, because she didn't know where the fight was.

She could only imagine the situation from the inner voices of Qin Tian and Issei.

Mio could hear the inner voice, meaning she was a heroine!

Of course Mio didn't know this yet, she was just living her life as usual and considered the inner voice a kind of entertainment in her head.

"The truth is at the McDonalds restaurant, Mio-sama. It's not far from the cafe we're at right now."

Maria said while correcting the correct name of the restaurant.

Mio's lips twitched.

"Isn't that the same thing? McDonalds is a fast food restaurant after all.

"But Mio-sama..."

"Enough, don't continue."

Mio raised one hand in front of Maria's face, she drank the juice on the table and said. "Let's go there now."

"Okay, Mio-sama let's go."

Then the two of them walked out of the café and walked towards the McDonalds restaurant which was quite close.

On the way the two walked together like a pair of sisters.

Maria asked idly.

"Mio-sama, Mio-sama, do you still hear that inner voice in your head?"

"Yes, I can still hear those voices. Do you still?"

Mio looked at Maria, she knew Maria could also apparently hear Qin Tian and Issei's inner voices.

Actually, she and Maria already knew that both of them could hear other people's inner voices as well.

They were both surprised at first, but quickly got used to it, and would sometimes talk to each other about the content of the inner voices they heard.

"I still am! I'm getting more and more curious about the owner of that voice, especially Qin Tian! It seems like he's very strong, if only we knew where he was, we might be able to ask him for help."

Maria said earnestly.

After hearing the voices in her head for quite a while, she was very interested in finding the man named Qin Tian whose voice she often heard.

As for the protagonist Issei? She seemed to be still offline after fighting with Qin Tian before.

The person was said to be in a coma, so he was probably being hospitalized or something.

Well, she didn't want meet with Issei, because he didn't seem like a good person for her and Mio-sama to meet.

Mio sighed.

"Even if we meet him, I doubt he'll help us."

"Why do you doubt it Mio-sama? Qin Tian seems like a good person, even he helped that heroine named Asia Argento.a few days ago."

Maria also knew about this, and she did have a good impression of that man named Qin Tian.

"But our situation is complicated and not as simple as Asia Argento... Are you sure Qin Tian will help after knowing our situation?"

"That..."

Maria hesitated to answer.

Mio shook her head and patted Maria's head.

"Forget about it. Now we have to acting well when we meet the people waiting for us at the restaurant.".

"Alright Mio-sama."

Maria complied, then the two of them finally arrived at the restaurant.

After entering the restaurant, Maria looked around for the person in her memory.

"That person is sitting over there Mio-sama."

Maria pointed towards a brown-haired man with glasses sitting in the corner of the restaurant.

Mio also looked at the man's direction and nodded, she was about to walk towards the man with Maria, but suddenly she felt like peeing.

Strange, even though she didn't drink too much in the cafe before.

"Maria, you go there first. I'll go to the bathroom for a while."

"Oh, okay Mio-sama."

After that, Mio went straight to the women's bathroom inside the restaurant.

Inside the bathroom, she peed for quite a while which made her sigh patiently.

Suddenly she heard the bathroom door she entered open, making her startled and hurriedly put on her pants.

The person who opened the door was a man!

She was about to scream, but the man quickly covered her mouth with his hand.

Bastard!

Remove your filthy hand from my mouth!

But she could only say that in a muffled voice.

The man spoke with a panicked expression.

"Wait a minute!"

"Please don't panic and listen to me for a moment!"

"You misunderstood, okay?"

"The sign on the door said the door was broken, but I realized it too late!"

"We're both victims!"

Shameless man!

Mio was angry, like she was being harassed in the bathroom right now.

She tried to remove the man's hand from her mouth, but the man was too strong, she can't even push him away.

But that's not all, the moment the man spoke that she misunderstood, he continued to approach her, even pressing her body against the wall!

This man is a cheater!

She wants to attack the man in front of him using magic, but somehow her magic couldn't be used.

Why at a time like this?!

This makes no sense!

"Please calm down, okay?"

"I'll release your mouth, please don't scream."

The man smiled like a gentleman, yet his body was dishonest and continued to press her against the wall.

Making her doubt, did this man really accidentally peep at her in the bathroom?

She was about to nod so that the man would understand that she wouldn't yell, of course she was lying about that.

Even though she was 70% sure that the man seemed to have really accidentally peeked at her, but she would still yell and plan to slap him for touching her!

She felt she was being harassed, making her unable to accept the man's request not to yell.

But before she nodded, she suddenly heard a voice in her head, like when an inner voice is heard.

{Ohhh! F*ck this girl is really pretty like in the anime! Look at that red hair and pink eyes. This is really a fictional beauty! Makes me so excited!}

{Oops, calm down, I need to calm down. Now I have to pretend to be a gentleman, although I'm enjoying pressing her body against the wall right now. I must be patient and must not rush, don't ruin my cool and calm image, after all this girl will be mine in the end.}

What is...

Mio was dumbfounded at the inner voice she heard, clearly it wasn't Qin Tian's or Issei's.

Then who did that voice belong to?

But it seemed to belong to the man in front of her...

The other heroes were also dumbfounded, they heard a new voice they didn't recognize.

In the underworld, Qin Tian who was watching people practicing was also dumbfounded.

[Whose voice is it? It's not Issei's voice...]

[Damn, am I hearing another man's voice in my head? Ahh! Ahh! I've heard enough of Issei's voice in my head, now there's another? And it's also a man?]

[Is this the other protagonist?!]
