Ten calculations?

"What is the Ten Heavenly Machines?"

Chu Yun subconsciously blurted out that he didn't know what the Ten Heavenly Machines here had to do with the Ten Heavenly Machines on the Azure Planet.

In fact, there is no qualitative definition of what the Ten Calculations of the Heavenly Machines of the Azure Planet are, and the so-called Ten Calculations of the Heavenly Machines that Chu Yun saw from the Nine Chapters of Arithmetic and some other ancient books are just individual representative arithmetic problems collected by some people.

These arithmetic problems are really profound truths that the ancients couldn't understand even after racking their brains, but for Chu Yun, a product of nine-year compulsory education, although there are some difficulties, most of them still know the solution, but they don't want to spend their minds to figure it out.

There is such a thing as the Internet, what arithmetic problems do you need to count with your fingers?

The reason why Chu Yun subconsciously blurted out was just that he was too curious, as for whether Xue Wuhua knew it or not, he probably couldn't understand it without thinking about it.

Sure enough, Xue Wuhua was stunned for a moment, and after hearing Chu Yun's words, he shook his head with a wry smile and said: "Even the old man of Tianji and the Xuannu of Tianji can't solve the ten calculations of Tianji, even if the old man is interested, he will not delve into it, not to mention that the old man is not interested at all." ”

Obviously, Xue Wuhua is also a person who doesn't know the content of the Ten Calculations of the Heavenly Machine.

Chu Yun looked at the people around him, everyone around, you look at me, I look at you, a group of people who even have to count the addition and subtraction within a hundred for a long time, where can the knowledge involve this?

However, many people naturally set their eyes on Chu Yun.

Xue Wuhua once said that the path Chu Yun was going to take was similar to Mu Qianqian's, in this case, whether the Ten Heavenly Machines could be solved or not, it was also a point of curiosity for everyone in Chu Yun, so naturally they all looked at it.

Chu Yun pursed his lips and said, "It's useless for you to look at me, I'm not very good at arithmetic!"

This is not bad at all, compared to those people on the Azure Planet, Chu Yun is simply like a layman.

Not to mention those famous mathematicians, they are the top students in major schools, and it is also a big deal to find someone who can beat Chu Yun.

Chu Yun just happened to know the ancient lectures of some algorithms and the descriptions and solutions of some examples, and most importantly, it was Chu Yun who traveled to Xianyun Kyushu, which is where half-hung mathematics comes in.

Xue Wuhua had a look on his face that I believe you are a ghost, and patted Chu Yun on the shoulder with a smile and said: "The old man said that your luck is against the sky, not to say anything, if the old man guessed correctly, this time the heaven and earth in the extreme north is from the ruins of the Tianji Palace, whether the secret is opened The old man does not dare to judge, but there are some situations, let's go and see." ”

With a smile on his face, the head of the Northern Royal Family stepped forward and said: "Chu Yun Xiaoyou's great kindness to the Northern Imperial Family, the old man doesn't dare to say thank you, but the honor of the foreign surname elder is none other than Chu Yun Xiaoyou, from today on, whenever there is a sending, the Northern Imperial Family will not hesitate to ......."

Speaking of this, the old man of the Northern Imperial Family Master looked at Chu Yun sourly regardless of the people around him, and then said: "Regarding the ruins of the Tianji Palace in the Far North, the old man knows something. ”

"Oh?"

Hearing this, Chu Yun's eyes lit up and asked, "The ruins of Tianji Palace, is there really a secret hidden?"

Before the head of the Beiyu family could speak, the Han Zhu next to him jumped to Chu Yun's shoulder and said: "Boy, you don't care if he has a secret secret, let's go and see, Tianji Palace still has something, if you go late, you may be taken by someone else." ”

The head of the Northern Imperial Family laughed, shook his head and said, "This ...... Pig Daoyou, obviously I don't know much about the ruins of Tianji Palace. ”

Pig...... Pig friends?

Chu Yun almost didn't burst out laughing, and looked at Han Zhu with a strange expression.

Sure enough, Han Zhu looked uncomfortable, saw Chu Yun looking over, glared and said, "What do you see, I have never seen such a handsome and chic pig?"

Chu Yun laughed, he really couldn't help it, even the Butterfly Mulberry Fairy and the Qingyue Fairy next to him couldn't help but laugh and turned their heads.

With a solemn look on his face, the head of the Northern Imperial Family said: "The Northern Imperial Family is where the Northern Imperial Qingzhou is located, and I have also visited the ruins of the Tianji Palace several times to investigate, but the phantom array in it is that even the ancestors can't see through it, and they almost can't get out, and the long-term cracking has not progressed, and the Northern Imperial Family has been changed by the dragon vein, so I didn't take this matter to heart." ”

Phantom Array?

Chu Yun asked curiously, "What kind of phantom array?"

The head of the Northern Imperial Family said with a wry smile: "It is said that it is the Phantom Array, but it is just the name of the Northern Imperial Family, the valley there looks unremarkable, but we just can't go to the valley, and as we walk, we lose our way, always going around in one place, and the old man can conclude that for so many years, even if it is a saint or a great sage, there is no one who can successfully walk in!"

Oh yo!

Chu Yun's eyes lit up, this Mu Qianqian's attainments in the formation had obviously surpassed the understanding of the vast majority of people in Xianyun Kyushu, which was a bit interesting.

Looking at it this way, Senior Brother Ben has cleared the wasteland this time?

Chu Yun turned his head to look at Han Zhu, and sure enough, he found that the eyes of this thing were also shining, obviously, he thought of going with him.

One man and one pig glanced at each other, and laughed.

Whether you can go in is another matter, the momentum can't be bad!

"In that case, what are we waiting for, let's go and see. ”

As he spoke, Chu Yun was about to walk forward.

The head of the Northern Imperial Family suddenly said loudly: "Chu Yun is slow!"

As he spoke, the head of the Northern Imperial Family made a move in the shocked eyes of countless people, and there was a buzz, and in the ice lake, a ball of golden light flew towards everyone.

Countless people's eyes lit up, and they looked at the long sword standing in the air in front of them, and their faces showed a look of horror.

This is a nearly transparent long sword, made of ice, exuding a cold air, which makes people feel like they are shocked when they look at it, as if they are facing endless fierceness.

Obviously, this longsword is not ordinary.

Sure enough, the head of the Northern Imperial Family said in a deep voice: "This sword is called Yutian, and it is a holy soldier used by the first ancestor of the Northern Imperial Family, but in a life-and-death battle in the ancestor's later years, the sword spirit of the Imperial Heaven was injured and annihilated, but it is precisely because of this that it can become an ownerless thing." ”

Saying that, in the midst of a group of people exclaiming, the head of the Northern Imperial Family waved his hand casually, pushing Yutian towards Chu Yun, and then said: "This sword has been frozen in the ice lake for thousands of years, and no new owner has been found, and now the old man has nothing to repay, so he will give this sword to you, hoping that Yutian can shine in your hands again." ”

Hearing this, countless people around immediately burst into an uproar.

Nangong Hengtian on the side showed a look of shock on his face, and after pondering for a long time, his eyes lit up, with a strange expression on his face.

"This ...... Elder Hengtian, Yutian is the inheritance treasure of the Northern Imperial Family, I don't know how many people want to keep it for themselves, and even there are many saints and great saints who come to ask for swords without success, why did the head of the family give him to Chu Yun now...... Elder Chu?"

After Nangong Hengtian heard this, he took a deep breath and muttered to himself: "You don't understand, in terms of vision, we are not as good as the head of the family." ”
