It was a Balor, holding a sword and wearing metal enchanted armor, shouting loudly and unkindly.

Roy calls Yumia and passes the voucher Alice has given.

The doorman's expression froze for a moment, and he immediately put on a flattering smile, and led the way with a courteous face:

"Four guests, please."

Taken to a teleportation array, the four of them went up to the teleportation array and entered the teleportation coordinates, Reading Room 0.

Delivery completed.

Roy looked around.

This is a very large indoor space, a cylindrical library with neatly arranged books on the surrounding walls, extending up a hundred meters. Looking up, you can see that at the top is a transparent flower room, in which various potted plants are planted, and a ray of sunlight shines down obliquely, illuminating half of the collection.

There is a large table in the center of the flower room, and two people sit on chairs.

From the bottom view, you can only see the slender legs and delicate high-heeled soles that are close together.

"There's a teleportation array around."

Alice's voice came.

Roy looked around and found a small teleportation array, and the four of them stepped forward and were directly teleported to the top flower room.

Got off the teleportation array.

In addition to Alice, there is also a super beautiful demon royal girl, with long golden hair falling to her waist, with delicate jewelry, a dress full of lace and decorations with intricate craftsmanship, the skirt is no more than the knee, the long legs are covered with white silk, and she is wearing high heels, and her already slender thighs are even more sultry.

In addition to books, there are also delicate snacks and black tea on the table.

The two are bathed in the sun, and their bright blonde hair seems to be glowing, forming a hazy halo that envelops them, giving people an unreal sense of dreaminess, as if they are in an elaborate CG painting.

The various flowers in the flower room exude a faint floral fragrance, constantly drilling into people's nostrils.

Roy was stunned.

Until the blonde girl stood up and beckoned to Lolina and Lilina.

"Ahh

Hearing that familiar voice, Roy immediately confirmed that this Demon Imperial Maiden was Vivian.

It seems that this is her true nature.

The face is better-looking, the legs are longer, the chest is larger, and the waist is thinner. The hair has turned blonde, and with the unique sense of luxury and sacredness of the Demon Imperial Family, it is three points more beautiful than before.

Roy's eyes moved a little.

People can be so beautiful.

Vivien noticed Roy, snorted, and looked away proudly. Enthusiastically pulled Luo Lina and Lilina, the two cat girls began to be a little restrained, and under Vivian's warm greeting, the two slowly let go of their restraints, talking and laughing.

Roy shrugged his shoulders and pulled a seat to sit down.

Alice looked at Stewart.

Roy Road:

"My friend."

"Hi, hello."

Stewart was very calm, don't expect him to react in a normal way. After introducing each other, Roy said:

"Where's the book I want?"

Alice waved her hand, and there were a bunch of books on the table.

Roy flipped through it, he had indicated what he wanted, and put the book away satisfied.

Alice took out a small notebook and asked Roy to ask questions about mathematics, but Roy didn't hide it, and taught him everything, all of which were some basic mathematical problems, and there was nothing difficult. Of course, Roy doesn't say it all at once, teaching only a small part a week, a little bit in exchange.

Vivien and Alice are smart and basically understand everything.

It's boring for Roy to be a teacher.

"A theoretical system and conceptual tree about the foundation of the six elements of magic that you have improved."

"I'll tell you more about this later, you learn math well first, otherwise you won't understand what I'm saying at all."

Vivien questioned:

"You're not lying to us, are you?"

Roy didn't speak, just spread his five fingers upward.

Six elemental spheres appeared in his hand, distributed in a regular hexagonal shape. With the flow of Roy's magic and spiritual power, these spheres continued to grow, and finally converged towards the center, and the six elements fused together without any conflict, turning into a small colorful ball.

The eyes of everyone present widened.

It's a fusion of six elements!

"How did you do that?"

Alice asked, breathless, staring at Roy.

Roy shrugged and said:

"When I give you the theoretical system and concept tree of the foundation of magic, you can easily do this."

The eyes of the people in the room staring at Roy were a little different, excited, scared, shocked, impatient, disbelieving, etc.

Vivien bit her lower lip, looking aggrieved, she wanted to refute Roy, but there was no excuse or reason.

Roy clapped his hands and smiled:

"That's all for today's study, let's try the drink produced in my Demon King City."

Roy took out a bucket of Fat House Happy Water and placed it on the table.

Lolina and Lilina immediately became excited, erecting their ears and shaking their tails, waiting for Roy to feed. Seeing that the two of them were full of anticipation, Luo Yi first poured two cups of fat house happy water for the two cat girls. The two cat girls happily held the cups and licked them with their little tongues.

Pour Fat House Water for Alice, Vivien, and Stewart.

Vivien said disgustedly:

"What is this? Witch's Elixir? It's cold, why is it bubbling? ”

"It's a drink~"

Roy doubled himself, drank it all, and exhaled comfortably after drinking.

"Look, drink it like that."

Stewart picked up the cup and drank it in one gulp:

"There's no smell."

"Do you have a tongue?"

Roy asked rhetorically.

Stewart was silent.

Alice and Vivien glanced at each other, and the two gracefully held their glasses and took a small sip of the lady.

And then.

"Ahem!"

The two coughed together, and the fat house happy water almost spilled, and hurriedly put down the cup and covered his mouth.

"This ...... What is this?! ”

Vivian stared at Roy with her waist thrust on, pretending to be majestic, but unfortunately she didn't know that she would only make people think about it like this...... Ahem.

Roy poured himself a glass and said:

"It's just a little stimulating, but it tastes good."

Alice didn't speak, but continued to pick up the cup and take a sip. If you are prepared this time, you will not be choked. Her eyes lit up, and she quickly finished her glass.

Seeing this, Vivien also tried to take small sips, drinking slowly, and after a while, she finished a glass.

The two pushed the cups over.

Fill up another glass.

Luo Yi propped his chin in his hands and stared at the two Demon Emperor girls with a smile.

Vivien was a little shy and glared back.

"Don't you think it's rude for you to do that...... Hiccup~......"

Vivien hurriedly covered her mouth.

Roy chuckled.

Vivien let go of her little hand and wanted to speak again.

"Hiccup~~~~"

Alice on the side also started.

The two of them covered their small mouths and endured it desperately, their little stomachs bulged and were round.

Roy Road:

"If you hold it like this, your qi will go down, and you will fart in the end."

The faces of the two girls turned white.

Stewart, who had not spoken, suddenly said:

"Oh my God! Roy, how did you get the two of them to have their bellies bigger? That's too fast, right?! Is this what you are talking about, staring at who is pregnant? You've made it?! ”
