After listening to Ye Qingyin's introduction, Mu Heng roughly understood that this was a mathematical problem, the topic was a rich commercial bamboo basket containing copper coins, of which there was only one copper coin in the first bamboo basket, two copper coins in the second bamboo basket, three copper coins in the third bamboo basket, and so on, there were 1,000 copper coins in the 1,000th bamboo basket, and asked the rich merchant how many copper coins were in this thousand bamboo baskets.

Knowing the general meaning, Mu Heng sighed in his heart, it turned out to be just a topic of summing the difference series, or the most basic difference series.

"This merchant is really strange, can't he exchange good copper coins for silver taels, why do you have to work so hard to load copper coins." Luo Yunjin heard the question, but it was a big one, and he couldn't help but blame the rich businessman who didn't exist.

"What do you know, people are here to solve the problem, and the environment created is not compatible with reality." Liu Qing'er understood the meaning of the topic this time, but she didn't know the reason, so she could only find fault with Luo Yunjin.

Luo Yunjin didn't want to ignore her, the eldest brother didn't talk about the second brother, and no one laughed at anyone.

"I roughly summed it up, and this question boils down to one plus two, plus three, all the way to a thousand, and find the sum." Ye Qingyin had obviously figured out the essence of this sequence. But it stops there, it seems simple, but there is a huge amount of calculation, and it is not a question that can be answered in a while.

Mu Heng looked at the other people on the field, and there were not a few who could get the same result as Ye Qingyin, but it was a little difficult to calculate this problem by using calculations.

The amount of data is so large that it must be counted by several people, otherwise it will not be finished in three days and three nights. If the amount of calculation is large, it is easy to make mistakes, so no one here has calculated any credible results.

It's troublesome to add up with the current Arabic numerals, not to mention that the calculation is still in use at this time. As long as one person in the middle makes a mistake, it will not be the right outcome. I can't review the calculation process, and I don't even know how to check it.

Fortunately, the first question couldn't be easier for Mu Heng. The most basic equal-difference series, even the formula is too lazy to apply. However, it is not appropriate to say it now, for fear of attracting unnecessary attention.

Luo Yunjin and Liu Qing'er had already given up the study of the topic, only Ye Qingyin was still frowning, pondering the algorithm of the topic. This question is difficult to say, and it is not difficult to say that it is not difficult, after all, as long as you can use the calculation chip, you can fiddle with it.

But this is a huge amount of calculation, and it is extremely difficult to get the right result without the slightest error. She likes to delve into problems, has a different interest in the topic, and after explaining the topic to Mu Heng, she has been thinking hard, thinking about whether there is any easy way to calculate the answer.

"Senior brother, do you have eyebrows?" Luo Yunjin has never been interested in numbers, but when he thought of the ruler invented by Mu Heng, he had honey-juice confidence in Mu Heng, and asked with anticipation.

Hearing Luo Yunjin's question, the other two people also looked at Mu Heng.

"It's not hard." Mu Heng didn't want to hide it from them, so he told the truth.

"Huh?" Ye Qingyin was surprised when she heard this, she had been thinking and meditating since she came in the morning, but she had no clue, and now Mu Heng just listened to what she said about the topic, so she answered so firmly, which really made her a little unbelievable.

But as a person who understands Mu Heng, she believes what Mu Heng said.

"Can you really solve the problem?" Liu Qing'er looked around at the people who were still struggling again, and asked with a curious and puzzled expression.

"Hmm."

"Great, senior brother, I know that senior brother is the most powerful, tell me what the answer is?" Luo Yunjin was proud of his trust in his senior brother, so he immediately wanted to announce the answer so that this group of people would be envious.

"Don't rush yet, wait until you finish reading the other four questions. If there is something I don't know, then it is not appropriate to disclose the answer, and I will explain it to you when I go back. Mu Heng politely rejected Luo Yunjin.

"What the layman said is reasonable, if you can answer all of them, then there is a need to show your face. As long as there is a question that cannot be answered, it will not attract attention. Ye Qingyin understood what Mu Heng meant and agreed.

"Senior brother, why did you come?" Not far from the bulletin board, a familiar voice sounded in the ears of the four people, and then a white slender figure appeared in front of the three people.

"Senior brother, why are you here?" Mu Heng saw that the person who came was Lu Siqi, and he couldn't help but be surprised.

Mu Heng's "junior brother" caused Liu Qing'er and Luo Yunjin to be speechless, wondering whether Mu Heng knew that someone was a daughter.

However, although the two of them don't look down on Lu Siqi, they are not nosy enough to expose other people's old secrets. can only let Mu Heng, who doesn't know whether he really doesn't understand or fake, shouts out this "junior brother" without any psychological pressure.

Ye Qingyin's weak temperament is destined to not like to mix with things that have nothing to do with him.

"There's no need to be so surprised, brother." Lu Siqi replied to Mu Heng without being salty.

"Not either." Mu Heng looked at the familiar Steward Zhao behind Lu Siqi, as well as several bookkeepers with the same beard, and the table of the Eight Immortals was full of bamboo calculations.

It turned out that Lu Siqi also came to participate in the Saiwen Meeting, and even the domestic servants brought it, so he must have been immersed in the first math problem just now. Thinking of this, Mu Heng's heart swelled with infinite emotion.

If Lu Siqi is just to explore the purpose of the National Teacher's Tournament, then as long as he understands the general situation and then stares at the movement of the scene, there is no need to really participate, after all, the opportunity to practice is nothing for Lu Siqi.

Now that he came here early with his servants, there would be no other purpose except for the matter of Mu Heng Daoji.

"Thank you, junior brother." Mu Heng didn't know what words to use to express his gratitude in his heart, and he could only mean it verbally.

"Hey, senior brother, look at what you said..."Lu Siqi saw that Mu Heng had changed her usual smug appearance and became very emotional, and she was still a little uncomfortable.

Mu Heng looked around at everyone around him, whether it was Luo Yunjin, Ye Qingyin, Liu Qing'er, or Lu Siqi, they all came to participate in the Saiwen Meeting.

They knew very well that there was a conspiracy behind the Severn Society, even against them, but they did not hesitate to risk their lives to help them get a way to reshape their spiritual roots.

I thought that Liu Qing'er was an ordinary mortal woman, but now she "said that it was a coincidence" to catch up with this Saiwen Society, and the person who suddenly appeared during the sensitive period, if it was really just a coincidence, Mu Heng didn't believe it a hundred times, so he didn't wait to ignore it anymore.

Things are gathered by like, and people are grouped. Whether this Liu Qing'er is a person in the Dao Sect or not, it is inevitable that he has cultivation on his body.

Mu Heng didn't know what to use to repay them, and all he could do now was a simple thanks: "Thank you." ”

"Oh, senior brother, what are you talking about?" Luo Yunjin sneered. Since I met Mu Heng, I have never regarded him as an outsider, seeing Mu Heng so polite, it is too much to see outsiders.

"I'm not here for you, I'm just curious." Liu Qing'er didn't have the right mouth, her face was full of satisfaction that was recognized by the other party, but she didn't admit it.

Ye Qingyin is still as calm as ever, but responds with tenderness full of maternal brilliance.

"How's it going?" After speaking, Mu Heng then asked about Lu Siqi's calculation progress. Seeing the account room on the table wiping the sweat from his forehead from time to time, Mu Heng knew that their work was not easy.

"Hey, this morning, it's only one hundred and fifteen, and if it is one thousand, it is estimated that it will take at least four days." Lu Siqi said dejectedly.

"It's going to take so long." Luo Yunjin didn't know how to calculate a copper coin, it was so laborious, it took four days to calculate, which made her a little unimaginable. Look at Mu Heng again, what the senior brother said is not difficult, and I don't know how much time it will take.

"The bigger the numbers get in the future, the more complicated it will be to fiddle with the calculations, and the progress of the calculations will be slower, and four days is already considered a quick one." Mu Heng looked at Luo Yunjin and explained.

"Ouch, I don't know how many of the most outstanding protector generals in the entire Star Country have counted, but I have already counted two hundred and two." The discordant voice interrupted the discussion on Mu Heng's side, and his words were full of pride in himself and belittlement of Mu Heng's side.

Mu Heng is also strange, no matter where he goes, there are always some who like to pretend to be bi and want to be a bad guy. But if you pretend to be too much, it will be very embarrassing, and if you don't get it right, you will be struck by lightning.

The people who came over, dressed in gorgeous clothes, gave people the feeling of being a monkey, obscene and domineering temperament, and a proper style in the ya. Looking familiar, this is not Dong Cang, who robbed the people's daughter that day.

"What are you going to do?" As soon as Lu Siqi saw this guy, he turned cold, and he couldn't wait to beat him up on the spot with a disgusted face.

"Everyone is here to participate in this Saiwen meeting, of course I can come, after all, with fairy fate as a prize, it is very attractive." Dong Cang put his hands behind his back, and his head looked up at forty-five degrees, showing the gentleness of the second generation of officials.

Mu Heng was a little surprised by Dong Cang's high profile at this time. The last time he was scared away by Lu Siqi in a few words, this time he took the initiative to provoke, could it be because of the support of the demon clan?

"It's just you, a guy who doesn't learn and doesn't know how to do it, and you still want to win this championship?" Lu Siqi has a certain understanding of Dong Cang, a guy who does all kinds of evil, where can he do knowledge.

"That's not exactly. Didn't I tell you just now, I've already counted two hundred and two. Dong Cang's forward-facing nostrils blocked his eyes, and the hands stuck in his waist and his right leg that kept shaking made Mu Heng want to beat him down.

"The villain is ambitious, but he started half a day early, and he felt that he had the capital to show off his might. How fast the calculation is, and whether you can get the right result is a matter of two questions. "Lu Siqi is not angry, he has been chasing Dong Cang since he was a child, when did he have such courage to dare to provoke himself.

"Hey, the accounts of the General's Mansion in my town are all dedicated to taking care of the money village, and it is not easy to calculate this account." Dong Cang couldn't help but feel a little frightened when he saw Lu Siqi's imposing appearance. The shadow of being played by Lu Siqi at a young age is not easy to eliminate.

According to his usual habits, Lu Siqi rushed up and punched and kicked him, making it difficult for his parents to recognize. However, with Mu Heng present, Lu Siqi couldn't help it, not wanting to give him the impression of a man's wife.

"How about it, General Lu, I'll ask you if you dare to bet with me." Dong Cang saw that Lu Siqi didn't speak, so he felt a sigh of relief, and then his face was full of obscene smiles, and he opened his teeth and claws to stimulate Lu Siqi.

Dong Cang, who has always seen himself like a mouse seeing a cat, now dares to openly provoke, how can Lu Siqi swallow this breath. As a general, she shouldn't have been so impulsive, but as the leader of the young generation in the capital, when did Lu Siqi be so underestimated.

"Why don't you dare?" After Lu Siqi returned to Dong Cang, he realized that the calculation progress on his side seemed to be inferior to that of the other party, and he looked at his own account team with a little weakness, and his head shook like a rattle, and his heart suddenly sank to the bottom.

Sensing that something was wrong, Lu Siqi set his eyes on Mu Heng again.

Mu Heng knew what she was worried about, and nodded at her, reassuring her to gamble boldly.

With Mu Heng's encouragement, Lu Siqi became more confident and asked loudly, "How do you want to bet?" ”

"Take this first math problem to bet, the one who is fast and accurate wins."

"I agree."

"If you lose, you will send your general's mansion to me, do you dare?" Dong Cangcheng has a bamboo in his chest, and the bet is big enough.

"Why don't you dare. But what if you lose? Lu Siqi didn't think she would lose, and Mu Heng behind her gave her great confidence.

"I'm losing, that's impossible, I'm already seventy steps ahead of you, at least half a day ahead of you. However, since it is a bet, there must be a bet, otherwise I will also press my family's mansion? Dong Cang replied.

"Hmph, don't talk big, I don't believe you can be your father's master." Lu Siqi saw that the other party was also going to press the mansion, and sneered.

I am the head of our family, and there is nothing wrong with pressing the mansion. You are only the young master of the family, how can you decide whether to stay in the house?

"I..." only tried to speak quickly, forgetting that it was not my turn to be such a master. Dong Cang, who couldn't fight back against Lu Siqi, his face was pale, but he had nowhere to vent, so he could only grit his teeth and say hatefully: "Then what do you want?" ”

"Not to mention that you can't be your father's master, but if you do, what is there in your family that I can value?" Lu Siqi struck while the iron was hot, refusing to let go of a chance to hit him.

The current Lu Siqi is no longer what it used to be, and the mundane things in the mortal world don't mean much to her. Her current goal is the sea of stars, the end of the avenue, and the senior brother Mu Heng in front of her, how can she care about Dong Cang's two jujubes.
