It's time for dinner.

The family got together.

Helena's mother and daughter were also assigned seats, and under normal circumstances, servants were not allowed to serve at the table. But after a long time together in daily life, there are not so many rules.

The dinner was very good.

When Loya and Aranda saw it, their appetite increased greatly.

Loya asked:

"Who made dinner tonight?"

Lolina and Lilina proudly raised their little hands, receiving compliments from Loa and Elanda.

The two kitten mothers are very proud.

Under the influence of the maid's skin, Lilina's cooking skills have reached the pinnacle. There was only the sound of eating and grabbing things at the table, and no one cared about chatting.

After the meal, several people sat on the sofa, touching their round bellies, and moaning in pain.

After eating and drinking, Luo Ya began to pay attention to his son's career, saying:

"Roy, how is the development of Demon King City? Has the maze been built? Is the shaped hourglass on? ”

"Almost."

Roy didn't elaborate.

He didn't plan to open the hourglass of energy gathering, but wanted to convert the productivity of Demon King City into wealth through some other means.

Lolina raised her small chin and said proudly:

"The young master is amazing, he has already captured a team of brave men!"

Loya and Aranda were stunned.

Elanda raised her voice:

"Really?"

"Hmmm......"

Roy nodded.

The husband and wife became excited at once.

"Well done! It is worthy of Lao Tzu's species! Ha ha! Your father and I fought for the first time that year, opened the hourglass for 1 month, but were attacked by the brave. Those grandsons are very cunning, and they come to attack at night, how can there be a brave man who sneaks into the Demon King City at night? Who taught them? While I was still sleeping, they blew up the soul crystal. ”

"Mom, it took me two months to catch a brave man with a trap. At that time, I got a ransom of 5,000 element coins~"

The husband and wife reminisced about the past.

"Son, work hard. I'm worried about your abilities. My friend's friend's brother's daughter's daughter is very good, and she will graduate next year, do you want to see each other? Acquaintance? ”

"No...... No need ......"

Roy hurriedly waved his hand and rejected the offer of a blind date.

"Son, this can't be done, when will you get a partner and come back? You see, my mother and I got married when we were in school. ”

Roy was in the middle of his face.

When you are a nodding monk, you nod your head when your parents say anything.

The chat ended.

Loya and Alanda play with Amy, and Roy goes back to his room and calls Lolina and Lilina by the way.

"The development of Demon King City in the future, as well as my ability, don't talk about it casually, and neither can my family."

"Why?" Lolina asked puzzled.

"Because of trouble."

The entire Demon Capital advocates a fighting ethos, and the only way to recognize ability is to defeat the brave and plunder the resources of the brave world. Everything else is crooked. If Loya and Elanda find out that Roy is 'not doing his job', he will definitely have to mix doubles to correct his son's 'wrong' thoughts.

Lolina and Lilina suddenly realized.

The two had no intention of leaving, kicked off their slippers, and rolled around on the Roy bed.

Helena knocked on the door and came in, calling the two away.

Roy lay on the bed, called out Yumia, and went to the forum of the magic web. He found out that someone had left him a message, which anonymous person was last week.

Roy replied, and the other party replied in seconds.

"As for the basic research on magic you mentioned, I tried for a week and didn't find any patterns to speak of."

"There is a rule, the relationship between the two variables is f(x)=......"

Roy replied with a string of formulas.

It took 1 minute before the other side gave a reply.

"What is this?"

"It's a function."

"What is a function?"

"A mathematical tool."

"What is math?"

Roy was speechless.

As a traverser, his basic quality is not comparable to these demon kings.

Mathematics is the basic discipline of all things, but the research of the demon kings on mathematics only stays at the very simple four operations, and there is no concept of similar functions.

Lowy explains mathematical concepts.

As a result, a whole bunch of problems were pulled out, geometry, probability, calculus, matrices, and so on. If you don't learn systematically, you won't be able to solve the problem at all.

Roy got impatient.

One or two questions are fine, and he still has the patience to answer them.

This had to make him teach from scratch, and he didn't have the patience. After all, the two met in Pingshui and chatted, but he didn't want to teach boring at all.

Roy said a few words in response, wanting to end the conversation.

Suddenly.

[Ding~ You receive an anonymous transfer of 10,000 element coins, and according to the transaction rules, 20% will be taken as a handling fee. The actual arrival of 8000 element coins. 】

Roy's eyes widened.

After confirming that the collection was real, and his account book really had 8,000 element coins, Luo Yi only felt his little heart pounding.

His first reaction was to encounter a big sum.

The demon king is mostly an iron rooster.

This is the image left by Roy after ten years in the magic capital.

Elemental coins are used for the establishment of the Demon King City, and most of the Demon Kings are not rich. There is also a high amount of fees for transferring money between each other. The only people who can throw 1w element coins like this are those powerful demon kings, or their children.

Lowy is almost certainly the former.

The Demon King is the lord of a city, who doesn't have any servants?

When the king is used to it, most of the demon kings have arrogant personalities, and they can't tolerate other people's doubts about themselves, and it's difficult to pull down their faces and learn from other people's things.

A group of demon kings get together to socialize.

It's almost like bragging about how powerful you are, and whoever doesn't accept it will fight.

The children of those powerful demon kings are even more swaggering.

At school, that kind of guy Roy saw a lot.

In his opinion, this person who is willing to spend a lot of money to learn math knowledge is the first rare creature at the root.

"Tomorrow day off, can you teach me some math? I can pay. ”

The other party was respectful and respectful, and they all used honorifics.

Roy agreed.

Now that he is shy in his pocket, he has a way to get money, so he naturally won't let it go.

It's just that he asked Stuart to meet in the library tomorrow to discuss the development of Demon King City.

"Tomorrow morning, I'll go to the library to meet a friend. If you don't mind, you can come early and be at the Z-4 library in the Aurora District. He'll leave in the afternoon, so you can come to me at that time. ”

End the conversation.

Roy looked at the extra 8,000 elemental coins on the account, and it was a little inflated. Getting so much money at once is a windfall.

Roy couldn't control his heart.

If the other party is a young, beautiful, studious, and deceitful little rich woman, he can give full play to his personal charm and bragging...... Phew, excellent eloquence ability captures rest assured, and then ...... Again...... At last......

Thinking is like a wild horse, thinking wildly for 5 minutes.

Roy shook his head, sober from YY.

The reality is brutal.

How could I meet a young, beautiful, studious, and deceitful little rich woman?
