In the bathroom, a steaming cloud of water gathered above Chen Luo's head, and under the control of his spiritual power, the water element that had been heated fell like rain.

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

At present, the biggest effect of magic on Chen Luo is to facilitate life, the combination of water and fire magic, it is not too convenient to take a bath.

What he had just said to Isabella was, of course, just a joke.

He is not even seventeen years old now, and it is too early to discuss the matter of love.

Even if he really planned to marry and have children here, it would be a few years later.

In the bedroom, Isabella, who had finished taking a shower, wrapped herself in the quilt and thought about something in a mess.

She is just Blair's senior sister, not his wife, and Blair can socialize with whomever he likes, which has nothing to do with her.

But when Blair just said that she chose Alice, her heart still uncontrollably welled up with that uncomfortable feeling, as if she had been betrayed.

Knowing that this mentality is wrong, she can't control her thoughts.

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

......

When Chen Luo came out of the shower, Teacher Britney told her that Isabella had gone home.

The long winter break starts today, and no student wants to stay in school during the winter break, and in the last month before the new year, people are used to staying with their families.

Chen Luo has no family and no home.

Blair's late baronial father, the only son in the family, had some distant relatives, but since his death, those people have also cut ties with Blair.

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

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

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

Britney sat across from him and said, "It seems that there are only two of us in this building during the winter break." ”

Chen Luo is homeless, and Teacher Britney obviously has a 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 he can remember, Chen Luo spent the New Year with his family.

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

For the next whole week, Isabella didn't come to school, and Chen Luo's ears were much quieter, without Isabella, and no one disturbed his life with Teacher Britney.

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

In the past few days, in addition to cooking with Teacher Britney every day, he is practicing magic.

Now, the teacher-student relationship between him and Teacher Britney is not so obvious, Chen Luo asks her for magic problems, she asks Chen Luo for math problems, and they have been in this state for a long time.

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

The vegetables he bought that day were the freshest, there was no need to go to class, and there were no important things, so Chen Luo changed his previous habit of buying vegetables.

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

Chen Luo faintly heard them mention the "gold coin", his eyes flashed, and he moved some distance towards their position.

It's not that he's greedy for money, it's really because the amount of gold needed to fill the bottomless pit of the Magic Association is too huge, so that Chen Luo's mind is full of gold coins these days, and he must find a new way to make money.

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

The promotion of a junior magician requires a greater amount of spiritual power, and the consumption of new magic is still above Chen Luo's expectations, and he has poured out all the gold coins, which should not be enough to keep his spiritual power growing at the same rate as that of a magic apprentice before he is promoted to an intermediate magician.

It is conservatively estimated that in order to maintain the rapid growth of spiritual power, the Magic Association still needs five thousand gold coins to fill it.

And this is completely Chen Luo's own fault.

After all, if the Magic Association is compared to a store, other magicians can buy one or two things in this store at most, but Chen Luo wants to buy the entire store, and the gold coins spent are naturally a hundred times and a thousand times that of them.

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

"Since the last time Roselle solved all the bounty problems, it was finally possible to have a bounty, and it was solved again......"

"That question has been added to a hundred gold coins, I just found an idea today, but it's a pity, it's a pity, it's a pity......"

"What are you sorry for, I've already proven it, it's so late, one step, my hundred gold coins......"

......

Mathematics researchers, if they encounter a problem that they can't solve, are offering prizes to the Mathematical Society.

This is the same as posting for help when people in later generations encounter problems, but they are paid.

The vast majority of these problems will be solved by other scholars not long after they are released, and those that have not been solved for a long time will be left on the wall and accumulated.

Among them, if someone is interested in the topic of the bounty, the bounty will be raised, and a few days ago, someone offered a reward of ten gold coins, and someone added it to one hundred gold coins, and just this morning, it was solved by a scholar.

Listening to everyone's discussions, Chen Luo's eyes gradually brightened.

Although a hundred gold coins is nothing to him now, it adds up to a lot, and he has to live a careful life, and there are no problems for him to solve, so he can offer his own reward......

Think about it, if he offered a bounty of ten gold coins, if someone added it to one hundred gold coins, wouldn't he make a net profit of ninety?

If they add two hundred gold coins, he will net one hundred and nine.

If someone else adds a more bounty, then he can fill in the hole of the 5,000 gold coins of the Magic Guild as long as he has enough bounty questions.

The most regrettable thing for Chen Luo is that the 23 problems he solved originally had a very high bounty, but because no one had answered 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 an answer.

Just do it, after going home, the next day Chen Luo used ten gold coins to anonymously offer a reward to the Mathematical Association for a question.

What he offered was a proof of a geometric theorem.

The butterfly theorem is a theorem proposed by Horner in the early 19th century, and the figure of this theorem is like a butterfly, which is quite beautiful, and the mathematical researchers here like to study this kind of bells and whistles.

In order to pick out a suitable topic, Chen Luo spent a lot of thought, mathematicians have a soft spot for geometry, so he found a wonderful geometric theorem for them to prove, from previous experience, this kind of problem is the easiest to be rewarded.

It is said that there was once an extremely wealthy mathematical researcher who increased the bounty on a problem to 10,000 gold coins......

Although that problem proved to be unsolvable due to the lack of necessary conditions, it at least proved that there are also mathematical researchers who are stupid and have a lot of money.

Chen Luo was looking forward to such a stupid math enthusiast with a lot of money to increase the reward for this question, until Teacher Britney handed him ten gold coins.

"Just now I passed by the Mathematics Association, and I saw a math problem worth ten gold coins on the bounty wall, so I solved it easily. Britney put ten gold coins in Chen Luo's hand and said, "You can put away this money and keep it for the family to buy vegetables......

Thousands of precautions, home thieves are difficult to prevent.

Chen Luo guarded against other scholars, but not against Teacher Britney, sure enough, only seven auxiliary lines of proof questions were needed, which was not too difficult for Teacher Britney.

So he came out with a harder one.

This proof of the perpendicular group problem is much more difficult than the butterfly theorem, after all the auxiliary lines are done, several triangles and circles are nested with each other, and countless dotted lines and solid lines are intertwined.

Even so, in order to be sure, regarding the matter of the Mathematics Association, Chen Luo has taken the initiative to run errands for Teacher Britney in the past few days, so as not to ruin Chen Luo's plan because she is worried that the family's food money will not be enough.

Fortunately, this question did not disappoint Chen Luo, when Chen Luo directed and acted by himself, anonymously raised the bounty to fifty gold coins again and again, this reward question has attracted the attention of scholars, and one day, a scholar from a mathematical family in Apor City offered a reward of 200 gold coins.

Although Chen Luo paid fifty gold coins, he still made a net profit of one hundred and five, which was not a loss.

However, when he came to the Mathematics Society with the multi-page solution process, he found that the wall was empty.

Chen Luo looked at the blank wall in a daze, and exclaimed, ", what about me!"
