The Magical Guild is a bottomless pit that requires astronomical amounts of gold coins to fill.

Just now, Chen Luo was still worried about the matter of gold coins.

However, looking at the math puzzles posted on the wall, he found that he seemed to have found a new way to make money.

He looked at the young man behind him and asked, "Your name is Gal, right?"

Garr stood behind Chen Luo, and was puzzled, when a familiar voice suddenly sounded in his ears, he immediately raised his head and said respectfully: "Yes, may I ask if there is anything that can help His Excellency Blair?"

Chen Luo pointed to the wall in front of him and asked, "Do you have any extra backups for these bounty questions, I want to take them back to study and study." ”

"Yes. This request was not too much for an honorary scholar, and Gal immediately nodded and said, "I'll go get it for you right away." ”

......

After leaving the Mathematics Association, Chen Luo went to the market again, bought some ingredients, and bought a lock for his room, and when he returned home, Teacher Britney and Isabella had not returned.

They will definitely go home for dinner in the afternoon, and it is still early, Chen Luo steamed the steamed buns first, and then put the rice used to make porridge into the pot.

Although the main ingredient of bread and steamed bread is flour, and bread tastes better for many people, Chen Luo still likes to eat steamed bread.

As for Ms. Britney and Isabella, if they can't get used to eating steamed buns, there is bread in the fridge.

In addition to steamed buns and porridge, Chen Luo only made two side dishes, after all, it is best not to eat too much for dinner, in case Teacher Britney Spears or Isabella are fed fat by him in the future, maybe Chen Luo will be blamed in turn.

Women are extremely concerned about their figures, and they are often unreasonable, if Teacher Britney has a belly, Chen Luo is not sure if she will care about the relationship between master and apprentice at that time.

As for Isabella, she is more likely to be unreasonable.

Near lunchtime, Ms. Britney and Isabella appeared outside the door just in time.

Isabella didn't have much to do, only packed two bags, threw them on the sofa, and couldn't wait to sit down at the table.

Teacher Britney and Isabella are much more receptive to steamed buns than Chen Luo imagined, although they have never eaten this kind of food before, but this does not prevent them from learning Chen Luo to break the steamed buns first and then put vegetables in them......

Watching Isabella and Britney skillfully use chopsticks to pick up the dishes, Chen Luo was a little skeptical that they would still use knives and forks a year later......

Thinking of something, Chen Luo took out the bounty he received from the Mathematics Association and said, "Teacher Britney, this is the bounty for those two difficult problems, you can put it away......

Britney shook her head and said, "Take the money Blair, this is what I was going to buy you for ingredients." ”

Isabella raised her head and said, "Didn't you say okay, I'll buy the ingredients......

Chen Luo didn't dissuade Teacher Britney like Isabella, after getting along for so long, he had already figured out her temper, she was a very assertive person, even a little stubborn, and would not easily change her decision, so Chen Luo didn't shirk it again.

"Good night Teacher Britney, good night Sister Isabella......" After eating, Britney and Isabella cleaned up the dishes and chopsticks, Chen Luo said to them, and went back to his room.

When he returned to his room, he first installed the lock he bought today on the door to prevent Miss Britney and Isabella from breaking in.

Chen Luo is not ready to let Teacher Britney and Isabella know about the things that the Mathematical Association has offered to solve difficult problems, nor is he ready to use Blair's identity to complete them, whether it is the Nine Bridges problem or the riddle of Raus or irrational numbers, it can be attributed to his ingenious thinking, and it is possible for any scholar to do it.

But if he solves all the problems offered by the Mathematical Association, he can't explain it anyway, a scumbag of mathematics, because after reading the book for two months, he has a superior mathematical ability than all scholars......

Moreover, this kind of one-pot thing is too high-profile, Chen Luo just wants to make money in a low-key manner, and he doesn't want to attract the attention of others like before.

In addition, Chen Luo still has a lot of secrets that cannot be discovered, and a private space that is not disturbed by others is particularly important to him.

After locking the door, Chen Luo took out a few pieces of paper locked in the drawer, which recorded the problems of the Mathematics Association that had not been solved for the time being.

During the day, Chen Luo had already browsed these topics, he first picked out the questions he had ideas for, put them aside for the time being, and then picked up the quill and began to write hard.

In the kitchen, Isabella put the cleaned dishes on the table, looked back at Chen Luo's closed door, and wondered, "Why did Blair sleep so early today......

In his eyes, although Blair has the shortcomings of being greedy for money and not being a gentleman enough, he can't hide his biggest advantage, that is, his extraordinary efforts and diligence.

Isabella had never met anyone harder than Blair, he hardly missed any time to study magic, even on his days off he had to go to the Magic Society, and even forgot to cook for his favorite teacher Britney.

How could such a person go to bed after just having dinner, this is not logical, Isabella slowly approached Chen Luo's door with curiosity.

She moved to Chen Luo's door and gently pushed the door, but the door was not pushed open by a small crack as she expected, but did not move at all.

The puzzle on Isabella's face was even stronger, Blair's room was originally unlocked, and it was just getting dark, so he hid in the room alone and locked the door, it couldn't be that he was doing something bad inside......

Isabella knocked on the door, and after a while, Chen Luo opened the door, looked at Isabella standing at the door, and asked, "Is there something wrong with Senior Sister Isabella?"

Isabella looked into the room and asked, "Blair, what are you doing alone in the room?"

Chen Luo said: "I found a few math problems in the Mathematics Association today, I think it is very interesting, I want to try to see if I can solve it." ”

"What math problem, I'll take a look......" Isabella slowly paced into Chen Luo's room, it was still very early before her time to go to bed, she was a little bored by herself, and wanted to find someone to talk to.

And there are only three people here, Britney's identity is a teacher in the end, in front of her, Isabella is a little uneasy, although Blair is a little boring, but if Isabella chooses to chat alone, it is better for Blair.

The only thing that is bad is that Blair has been together for a long time, and her pocket money is always spent very quickly......

She picked up Chen Luo and copied a geometry problem, sat at the head of the bed and looked at it, Chen Luo didn't say anything, sat down at the desk and continued to solve the problem.

Isabella is indeed very smart, and in the talented St. Donnas College, she can be regarded as an excellent student with excellent character and learning, and under the teaching of Ms. Britney, she often gets full marks in mathematics.

However, she still had some delusions when she wanted to solve that geometry problem.

Although there are several ways to prove the seemingly simple geometric proof problem, the simplest method also needs to make eight auxiliary lines, and at the same time, it also needs to be applied to a geometric theorem that has not been discovered by mathematicians in this world......

The proof problem of the Mathematical Association is not difficult, but the process is a little more cumbersome, and this hidden theorem is the difficulty of this problem.

It took Chen Luo twenty minutes to finish the detailed proof process, and after putting down the pen, she realized that there had been no sound behind her for a long time, she looked back and found that the paper had been thrown aside by Isabella at some point, and she had kicked off her shoes and fell asleep wrapped in Chen Luo's quilt.

Chen Luo didn't pay attention to her, sorted out the process of solving that question, put it in a drawer, and copied it again, thinking about it seriously.

Although these topics can only be regarded as classical topics in the early stage of mathematics, the mathematics researchers at this time have studied geometry in depth, and even in later generations, they can also be used as the finale questions of the senior high school exam, which tests the students' real mathematical skills, and only a very small number of top students can make that.

Compared with the Nine Bridges problem, for Chen Luo, these problems are more challenging, but fortunately, he has a wealth of knowledge reserves, as well as a lot of knowledge ahead of the mathematical community, and solving these problems is nothing more than spending a little more time.

After some time, Britney knocked on the door, walked into the room, glanced at the bed, and was surprised, "Why did Isabella sleep here?"

Chen Luo said helplessly: "She was just sitting at the head of the bed just now. ”

Britney shook her head, picked Isabella up from the bed, and said, "Blair, you should go to bed early, you have class tomorrow." ”

Even if Teacher Britney didn't remind her, Chen Luo was ready to sleep.

Casting magic is very energy-consuming, he must ensure enough sleep, besides, Isabella has already warmed his bed, and her body temperature is still left in the quilt......
