In the bathroom, a cloud of steaming water gathered above Chen Luo's head. Under the control of his mental power, the water elements that had been heated fell like rain.

When I was having a snowball fight with Isabella just now, a lot of snow was poured down his neck and wet the clothes inside. Isabella had just finished taking a shower, and it was Chen Luo's turn now.

At present, the greatest effect of magic on Chen Luo is to facilitate life. When the water and fire magic are combined, taking a bath is simply not too convenient.

What he said to Isabella just now was just a joke.

He is now younger than seventeen years old, so it is too early to discuss love now.

Even if he really plans to get married and have children here, it will be a few years later.

In the bedroom, Isabella, who had already taken a shower, wrapped herself in a quilt and thought about something in her heart.

She is just Blair's senior sister, not his wife. Blair likes to date whoever he likes, and this has nothing to do with her.

But when Blair just said that he chose Alice, the discomfort still burst into her heart uncontrollably, as if she had been betrayed.

Even though she knew that this mentality was wrong, she could not control her own thoughts.

The girl's thoughts began to slide into the tangled abyss.

...

When Chen Luo came out after taking a shower, Teacher Britney told her that Isabella had already returned home.

The long winter vacation begins today. No student is willing to stay in school during the winter vacation. In the last month before the New Year, people are used to staying with their families.

Chen Luo has no family and no homeless.

The late baron father of Blair was the only son of the family and had some distant relatives, but since his death, those people have cut off contact with Blair.

Even though they have some blood relationship with Blair, in Chen Luo's eyes, they are no different from strangers.

Britney walked out of the room and asked, "Blair, are you going to stay at school during the winter vacation?"

Chen Luo nodded and said, "I have nowhere else to go, and Teacher Britney won't go home?"

Britney sat opposite him and said, "It seems that there are only two of us in this building during the winter vacation."

Chen Luo was homeless, and Teacher Britney obviously had family. As for why she didn't go back, Chen Luo didn't know.

However, it is naturally a happy thing for Teacher Britney to stay with him. Since I can remember, Chen Luo has spent the New Year with his family.

In this strange world, Chen Luo has long regarded Teacher Britney as his family.

For the next week, Isabella did not come to school, and Chen Luo's ears became much quieter. Without Isabella, no one disturbed his and Teacher Britney's life.

The only regret is that without Isabella, he has to sleep in the cold bed every day.

These days, in addition to cooking with Teacher Britney every day, he practices magic.

Now, the teacher-student relationship between him and Mr. Britney is no longer so obvious. Chen Luo asked her about magic problems, and she asked Chen Luo about math problems. They have been in this state for a long time.

In addition to academic exchanges, as is now, the situation of two people going out to buy groceries together is almost every day.

The vegetables I bought that day were freshest and there was no need to attend class, and there was nothing important. Chen Luo changed his previous habit of buying vegetables.

At the entrance of the Mathematics Association, Teacher Britney went in to submit the latest paper. Chen Luo was waiting outside with a vegetable basket and heard several math enthusiasts whispering something.

Chen Luo vaguely heard them mention the "gold coins", and a light flashed in his eyes and moved a distance towards their position.

It’s not that he is greedy for money, but because he fills the bottomless pit of the Magic Association, the amount of gold coins he needs is too large, so that Chen Luo is thinking about gold coins these days, and he must find a new way of wealth.

Two days ago, Chen Luo went to the Magic Association and replaced all the more than 12,000 gold coins with primary variant magic.

The junior magician needs greater mental power to advance. The consumption of new magic is still above Chen Luo's expectations. He spent all his gold coins, which should not be enough to keep his mental power as growing as a magic apprentice before he advanced to the intermediate magician.

Conservatively estimated that in order to maintain the rapid growth of mental power, the Magic Association will need 5,000 gold coins to fill it out.

And this was completely asked by Chen Luo.

After all, if the Magic Association is compared to a store, other magicians buy one or two items at most in this store, but Chen Luo wants to buy the entire store, and the gold coins they spend are naturally hundreds or thousands of times that of theirs.

Chen Luo moved to the people and listened carefully to their conversation.

"Since the last time Luo Shen solved all the reward problems, it was finally possible that a reward was solved again..."

"That question was added to 100 gold coins. I just found my idea today. It's a pity, it's really a pity..."

"What a pity, I've proved it, it's just one step late, one step, my one hundred gold coins..."

...

If mathematical researchers encounter problems that they really cannot solve, they will offer a reward from the Mathematics Association.

This is the same as people in later generations who have encountered problems and ask for help, but it is paid.

Most of these problems will be solved by other scholars shortly after they are published. If no one solves them for a long time, they will be left on the wall and accumulated.

Among them, if someone is interested in the reward topic, he will also increase the reward. A few days ago, someone gave a reward of ten gold coins and added 100 gold coins. This morning, it was solved by a scholar.

Listening to everyone's discussion, Chen Luo's eyes gradually became brighter.

Although one hundred gold coins are nothing to him now, he has to make a living by calculating the amount of money. There are no problems for him to solve, and he can offer his own rewards...

Think about it, the problem of his reward of ten gold coins. If someone adds one hundred gold coins, wouldn’t he make a net profit of ninety?

If they add two hundred gold coins, he will make a net profit of one hundred and nineteen.

If others add more rewards, then as long as he has enough reward questions, he can fill in the loophole of the 5,000 gold coins of the Magic Association.

What made Chen Luo the most regrettable was that the 23 problems he solved originally had extremely high bounties, but because no one solved them for too long, after the bounty period, the owners who added the bounty took back the gold coins.

After all, even Chen Luo himself would not invest so much money in a question that might not have answers.

He did it as he said, and after returning home, Chen Luo anonymously offered a reward from the Mathematics Association for a question the next day.

What he offered was a proof of a geometric theorem.

The butterfly theorem is a theorem proposed by W.g. Horner in the early 19th century. The graph of this theorem is like a butterfly, which is quite beautiful. The mathematical researchers here like to study such fancy things.

In order to select suitable questions, Chen Luo spent a lot of effort. Mathematicians have a special liking for geometry, so he found a wonderful geometry theorem for them to prove that from past experience, such questions are the easiest to be rewarded.

It is said that an extremely wealthy mathematical researcher once added a reward for a certain problem to 10,000 gold coins...

Although that question was finally proven that there were no necessary conditions that could not be answered, at least it was proved that mathematical researchers also had some stupid people with more money.

Chen Luo looked forward to a math enthusiast who was stupid and had a lot of money to add a reward for this problem until Teacher Britney handed over ten gold coins to him.

"Just just passed by the Mathematics Association and saw a mathematical problem worth ten gold coins on the reward wall, so I solved it." Britney put the ten gold coins in Chen Luo's hand and said, "Please keep the money and keep it for your family to buy vegetables..."

It is difficult to prevent any thieves from defending themselves.

Chen Luo defended against other scholars, but failed to defend against Teacher Britney. Sure enough, only seven auxiliary lines were needed to prove the question, which was not too difficult for Teacher Britney.

So he came up with something even harder.

This proof of the problem of the dwelling group is much more difficult than the butterfly theorem. After all the auxiliary lines are finished, several triangles and circles are nested with each other, and countless dotted lines and solid lines are interlaced. Not to mention proof, ordinary mathematicians feel dizzy at first glance.

Even so, in order to be foolproof, Chen Luo has taken the initiative to run errands on behalf of Teacher Britney in recent days, so as not to destroy Chen Luo's plan because she was worried that the family's food was not enough.

Fortunately, this question did not disappoint Chen Luo. When Chen Luo directed and acted by himself, he raised the bounty to fifty gold coins again and again, the reward question had attracted the attention of scholars. One day, he was rewarded with two hundred gold coins by scholars from a mathematical family in Yabo City.

Although Chen Luo paid fifty gold coins, he still made a net profit of 15 yuan, which is not a loss.

However, when he couldn't wait to come to the Mathematics Association with a few pages of problem-solving process, he found that the wall was empty.
