Arithmetic is closely related to everyone's life and will be used in all walks of life. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 The Ministry of Household Accounts needs to accurately calculate taxes and appropriations to various ministries; the Ministry of War has to accurately calculate the budget, salary, grain, and grass of the Ministry of War; relatively speaking, there are not many things that need to be accurately calculated by the Ministry of Rites and the Ministry of Criminal Justice, but they are not without need.

Not to mention the various ministries of the imperial court, even all walks of life are inseparable from calculation, which shows the importance of arithmetic, but countries still do not attach importance to arithmetic.

Not only Tianqi and Beichen, but also Tianwu, a country that values business, does not attach importance to arithmetic, and there are even fewer people who are proficient in arithmetic.

It's not that no one learns, but the court doesn't pay attention to it, in this era when you learn literature and martial arts, you can only sell goods to the emperor's family, the court doesn't reuse people who learn arithmetic, and naturally no one will study it.

Now that Xu Ziqi asked, Ji Yunkai wanted to have a good chat with Xu Ziqi about the role of arithmetic in the military, but ......

"General Xu, the calculation is not something that can be explained in three or two sentences, can we talk about it later?" Xu Ziqi has no foundation, she wants to explain to Xu Ziqi clearly the calculation speed, calculation of wind resistance, and calculation angle, and she has to explain from scratch, which takes a lot of time.

However, now that the soldiers and horses of the Demon Sect have surrounded Xiao Zhuangzi, they must lead their troops over as soon as possible, and there is no time to talk nonsense with General Xu here.

Although Xu Ziqi wanted Ji Yunkai to talk about it first, he also knew that nothing had been done, and there was no reason for someone to teach him, so he immediately nodded and said, "Yes." ”

Afraid that Ji Yunkai would lose it when he ran out of things, Xu Ziqi added: "Later, please ask the girl to tell us carefully." ”

In other words, they will seriously do what Ji Yunkai confessed, but they also ask Ji Yunkai to do their best afterwards.

There was no intersection with each other, Xu Ziqi just listened to Liu Yuan's words and came to help, and they didn't even know who they wanted to help.

Although as soldiers, they will obey orders, but there is a difference between doing things according to orders and doing things desperately.

With Ji Yunkai's hand, even if Xu Ziqi will not work hard for Ji Yunkai, he will do things seriously, instead of having to do it because of Liu Yuan's order.

"General Xu, don't worry, I will not hide my secrets. "Ji Yunkai is not a person from one of those famous families, she will not treat what she has learned as her personal property, and the education she has received allows her to teach everything she has learned to others without reservation, and she will not worry that others will trample her on the soles of her feet if they learn her things.

"Let's leave now, how about it?" With Ji Yunkai's consent, Xu Ziqi no longer delayed.

The matter should be done as soon as possible, and it should be done quickly, so that he could let Ji Yunkai talk about computing as soon as possible.

"Good. "Ji Yunkai doesn't know if the people from the Demon Sect have done it, it must be best to go earlier.

"I'll go back first, I'll leave it to you. Xiao Jiuan did not interfere with Ji Yunkai's decision from beginning to end, seeing that Ji Yunkai successfully made Xu Ziqi willing to do things for her, Xiao Jiuan left with confidence.

It is better to be able to make people do things willingly than to just listen to orders.

In addition to Xu Ziqi's soldiers and horses, there are also secret guards in the shadows to protect Ji Yunkai, and he doesn't need to worry about Ji Yunkai's safety.

"Okay, I'll be careful. "Being in the barracks, Ji Yunkai has a sense of security and is not worried about any accidents.

Xu Ziqi saw that Xiao Jiu'an was leaving, and did not stay, although General Liu didn't say anything, only asked him to bring troops to Heishi Mountain, but the king of Yanbei of the Apocalypse was in Heishi Mountain, he could guess some, but ......

As a subordinate, some things are guessed, and he can't say a word more.

Xiao Jiu'an returned the same way, returning to Xiao Zhuangzi from the secret road, and no one on the Zhuangzi knew that he had left halfway except for Xiao Jiu'an's henchmen.

Outside Zhuangzi, the people of the Demon Sect were still surrounding Zhuangzi, and during the time Xiao Jiu'an was out, they launched an attack, but unfortunately, their first attack ended in failure.

Don't look at the fact that there are not many people on Zhuangzi, but everyone brought by Xiao Jiu'an is a good hand, and the people arranged by Mo Qixi here are not weak, and there is also a master like Li Yuan, it is not easy for the people of the Demon Sect to rush in.

As soon as Xiao Jiu'an came back, his henchmen reported the situation outside to him: "Ninth Master, the situation outside is extremely unfavorable to us, after the first wave of attacks failed, the Demon Sect sent more people, and all of them were masters. ”

The three hundred disciples surrounding Zhuangzi were just ordinary thugs, the real main force of the Demon Sect was the Great Protector, and after fighting with Xiao Jiu'an's people, the Great Protector decisively transferred a group of masters from the sect.

Now, there are more than 20 masters around the Great Protector, and the strength of these people is above the seven sons of the Demon Sect, which shows how much the Demon Sect attaches importance to Xiao Jiu'an.

Let Li Yuan continue to drag. "Drag it until Ji Yunkai comes over with the soldiers and horses.

With the 5,000 soldiers and horses in Xu Ziqi's hands, whether it is an ordinary sect member or a demon sect protector, they can only become prisoners.

"Yes, Ninth Master. With Xiao Jiu'an in charge, the guard's high heart was relaxed.

No matter what happens, as long as there is their prince, they will not be afraid.

Outside, Li Yuan stood at the gate of Zhuangzi, confronting the Great Protector of the Demon Sect, the people of the Demon Sect did not move, Li Yuan did not move, and the two sides were so stiff......

"Great Dharma Protector, if this stalemate continues, it will not be good for us. "When the people of the Demon Sect saw the people on Zhuangzi and were surrounded by them, they still didn't panic for a while, and for a while they were beating drums in their hearts, and he always felt that King Yanbei had a backhand.

"I also know that dragging it out will not be good for us, but which of you is Li Yuan's opponent?" the Great Protector of the Demon Sect glared at the person beside him with a gloomy face.

The stared man's face turned pale with fright, and he still said dutifully: "Great Protector, why don't we go together?" No matter how powerful Li Yuan is, there is only one person, and there are so many of us, even if we consume him, we will consume him to death." ”

"Let's go together?" the Great Protector of the Demon Sect sneered.

This is a good idea, Li Yuan's reputation is too great, and he has an enmity with the Demon Sect, no one dares to confront him alone, if everyone goes together, there will be nothing to say.

"Okay, let's go together, no matter what, we must break through the defense line today and capture King Yanbei. "As long as the king of Yanbei falls into their hands, just one Li Yuan is not enough to worry about.

The Great Protector of the Demon Sect ordered that except for the two Great Elders and a few old men, everyone else would go with him to attack Li Yuan. With the Great Dharma Protector taking the lead, others have no objections.

"Kill him!" the Great Protector of the Demon Sect took the lead, followed by more than a dozen good players.

Li Yuan saw this group of people rushing over, he didn't worry but was excited: "It's just right to come, the old man is trying to slaughter you one by one." ”

If it weren't for King Yanbei's confession, try to delay the time and not make a move with the people of the Demon Sect, he would have killed all the people of the Demon Sect a long time ago......
