There were no Arabic numerals in this era, of course, not to mention linear equations of two variables. Mathematics, in this era, could only be called arithmetic at best, and those who studied arithmetic were, at best, accountants who were just trying to make ends meet.

People like this are just scratching the surface, and slightly more difficult math is still in its infancy. It will take at least a few hundred years for a master of mathematics to emerge! At this time, he really knows how to do it.

People who are more arithmetic are basically ascetics like Dong Ming...

At this time, the world was in chaos, and the selection of talents in various countries basically relied on recommendations. Some countries held imperial examinations without arithmetic. Therefore, arithmetic was not taken seriously at all. Questions like chickens and rabbits in the same cage were difficult for those in the Imperial College and Imperial College of various countries.

It is not difficult to get a PhD in mathematics.

Xiao Chen did not use the bimonthly equation at the beginning, but used some incomplete solutions from the ancient arithmetic classic "Sun Tzu's Suan Jing". However, judging from everyone's reaction, Xiao Chenxuan could easily deduce that although "Sun Tzu's Suan Jing" existed in

In this world, there are only some incomplete problem-solving methods, and it is normal for these people not to understand these incomplete problem-solving methods, so it is natural that Xiao Chenxuan said a simpler and easier-to-understand problem-solving method, and everyone is eager to know.

"This is called the equal sign, this is the plus sign, the minus sign, and this cross can be understood as a number that is not yet known..." Originally, Xiao Chenxuan didn't think so much at first, and just told everyone casually, but he really started to explain.

At that time, Xiao Chenxuan discovered that these scumbags from Zhanwu, popularizing the knowledge of linear equations in two variables to them was like teaching a group of children who had just entered elementary school, it was very brain-consuming.

But now that the explanation had begun, Xiao Chenxuan felt that he couldn't give up halfway, so he had to be patient and move forward bit by bit.

"That's it, after solving the two unknown numbers, it's the number of chickens and rabbits." It wasn't until about ten minutes later that Xiao Chenxuan breathed a long sigh of relief and finally popularized it to these scumbags from beginning to end.

Once again, I felt quite exhausted.

"It's really unbelievable that there is such a problem-solving method." Dong Ming couldn't help but admire when Xiao Chenxuan explained the problem-solving method.

As for the missions from several countries, in fact, they are not very interested in learning arithmetic. They just want to see if Xiao Xuanchen can really solve problems. Of course, most of the missions from several countries are students who will learn one or two and return to their own countries.

It's good to show off, and at the same time, it can impress the masters who teach them when they go back. But everyone thought for a while, and then tried out the correct answer to this question in their minds, and then used Xiao Chenxuan

This new way of finding a new way was really useful. It only took everyone two breaths. At this time, the eyes of everyone looking at Xiao Chenxuan were filled with all kinds of admiration.

Xiao Chenxuan, who had not pretended to be cool for a long time, saw the admiration in everyone's eyes, and actually analyzed it for everyone very kindly. No, Xiao Chenxuan was very proud, squinting and said: "It's incredible, isn't it? Otherwise, I will use other questions of the same type again.

Let me tell you."

Upon hearing Xiao Chenxuan's words, everyone in the banquet hall turned their heads towards Xiao Chenxuan and kept exclaiming.

"There are other ways? Then tell me about it."

Xiao Chenxuan curled his lips and said seriously: "First of all, you need to remember these new counting methods and symbols..."

Hearing this, everyone once again

Looking at those strange simple graphics, even though Xiao Chenxuan had just said it, they had never seen it before, and they were still very curious. The combination of these strange symbols turned out to be a new counting method.

Of course, everyone has received aristocratic education and has a profound background. Although this thing seems novel, it is not difficult to understand. After Xiao Chenxuan's simple explanation, it took a little time to neutralize this set of rules.

I was amazed in my heart. This method is undoubtedly much better than today's counting method, and it is more convenient and simple...

Seeing everyone nodding incessantly, Xiao Chenxuan suddenly felt that teaching and educating people was pretty good. These Zhanwu scum could fool themselves by just making up some story. If someone asked him if he didn't understand something in the future, would he make up a story?

The answer is also very good.

"Do you understand?" Xiao Chenxuan looked at everyone and asked expectantly.

Although he was in the process of several competitions, and although some people suspected that the process was a bit tortuous, Xiao Chenxuan felt that there was no shortage of talents in the banquet hall who could govern the country and love the people. If the Chu State were to dominate the world in the future, these personnel would learn more mathematical knowledge and be arranged in the future.

They are good at running the place. Thinking of this, Xiao Chenxuan feels a little comforted.

"No." But what Xiao Chenxuan didn't expect was that everyone in the banquet hall, except Dong Ming, denied it without any hesitation.

Hearing everyone's answers, Xiao Chenxuan could only say a bunch of dead wood, but what Xiao Chenxuan didn't expect was that Dong Ming, the only one who could understand, actually held his chest and took a few deep breaths, then dragged his body that seemed a little exhausted without looking back.

left.

Xiao Chenxuan won three out of three battles and won the prize. The banquet has come to an end. The rest of the trivial matters naturally have nothing to do with Xiao Chenxuan, especially the details of the hunting conference a few days later. Naturally, Huang Qiushui, the deputy envoy of the mission,

Discuss with the six countries.

Naturally, Xiao Chenxuan was also very happy, so if nothing happens in the next few days, I would like to make an appointment with Xu Qingchen to make love to me. I would just treat it as a trip for a few days. The only bad thing is that I win all of a sudden.

Although the Western Zhou Dynasty Li Gui was given to Xu Qingchen, it was inevitably targeted by thieves.

On the night after the banquet, the Chengying Sword brought back by Xiao Chenxuan was actually targeted by someone with ulterior motives. A group of men in black discussed in the novel not far from Xiao Chenxuan's house.

"Steal! Find a few good thieves to work with you. Look for the right opportunity tonight and find a way to steal the Shadow Sword for me. Whoever wants to solve this matter for me will be heavily rewarded." Good speaker.

Top Ten = Go all out and make a direct commitment to the people under you.

However, opposite the speaker, the man in charge of stealing the Shadow Sword for the man in black was not moved, but said in a deep voice.

"Master, although the Chu State Mission was attacked a few days ago, except for the death of some guards, the Chu State Mission did not lose anything. This proves that there is no shortage of experts around Xiao Chenxuan. Therefore, we want to steal the inheritance."

The Shadow Sword is not that easy, so I think even the thieving experts I send may not be able to succeed. If we miss it, none of us who go there may come back."

Hearing this, the man in black gritted his teeth and said, "Okay, then let the people who go put poison in the teeth. If you miss it, I will definitely take good care of your family."

"It's the master." The person in charge of stealing the Shadow Sword whispered.

The man in black nodded, and then told the people in front of him: "Remember, we are definitely not the only ones who are eyeing the Chengying Sword. You all should be careful."

The night was getting darker, and the area around Xiao Chenxuan's house was extremely quiet.

But at this moment, there was a trace of fire where the Shadow Sword was placed in the house where Xiao Chenxuan was. An Tingyong, who was in charge of patrol, and the soldiers of the escort army were shocked when they saw the bright one, because the bright place turned out to be Cheng Ying Sword.

The place where the Shadow Sword is placed.

After a while, there were actually figures fighting in the room where the Chengying Sword was placed. Even the fire was getting bigger and bigger, as if something had happened.

Of course, I don't know if someone suddenly attacked or what happened in the house, but no matter what the possibility is, Xiao Chenxuan's guards must rush there quickly. The Chengying Sword was won by the prince after the Duolun battle, so naturally they can't

Let an accident happen to Chengying Sword.

If anything happens to the Chengying Sword, how can they, as Xiao Chenxuan's bodyguards, be worthy of Xiao Chenxuan's painstaking training and trust in them.

However, the guards who placed the Shadow Sword seemed to be a little far away. Even if An Tingyong on patrol could fly over walls and walls, it would be too late for them to fly to the light of the fire.

But when they arrived at that place, it was too late. Several of the guards guarding Chengying Sword had fainted and fell in a pool of blood. Fortunately, the guards were only seriously injured and did not really die, but Chengying Sword did not know.

Whereabouts.

An Tingyong looked at this scene and didn't know what to say. In the past few days, our Chu State mission was attacked twice, which is unimaginable!

In order to understand the situation at that time, Anting Yong found the accompanying military doctor, looked at several guards and asked.

"What happened then?"

One of the guards seemed to feel guilty and a little scared and said: "At that time, a thick smoke blew in from the window. We suddenly became a little sleepy and couldn't help but want to take a nap. But after a while, a group of

The men in black entered through the window. When we reacted, the men in black rushed towards us and started hacking and killing me. So, we lit the curtains next to us and sent a signal to the generals, but

Those people were strong and strong. After a while, you and I were seriously injured and fell to the ground. Those black people took the Prince's Shadow Sword and ran away."

An Tingyong checked the scene, and based on what the two guards said, he roughly understood the situation at that time. The purpose of the black people was obviously the sword. However, don't these black people have brains? Don't confirm it either.

Take away the authenticity of the sword.

An Tingyong let out a long sigh. The prince was still very powerful. He had expected that someone would attack the Yingying Sword early in the morning, so he arranged for replacements early and minimized the number of guards guarding the sword. Thinking of this, An Tingyong looked at Xiao Chenxuan.

He smiled in the direction of the house, then turned to the guard behind him and said.

"What are you still doing there? The divine sword has been stolen. Why don't you report it to the authorities immediately?"

Hearing An Tingyong's words, the guards around him realized that the Prince had won the Shadow Sword and it had been stolen less than a day later. He must report it to the officials as soon as possible, otherwise how would he and others face the Prince.

"Yes, General, I'll wait here."
