The map was waited until the next day, and Zhao Ziyun personally sent it over.

After letting the traitor go last time, Zhao Ziyun and a group of spies were worried all day.

If it is a normal mission, it will not have any serious consequences, the problem is now related to the deployment map, and they still have the information in advance before arresting people, which also makes people run away, if the matter is transmitted back to the palace, they will all have to fall to the ground one by one.

Fortunately, Chen Ze suppressed the news for the time being.

After all, everyone makes mistakes sometimes, and there are indeed many difficult objective factors in the whole thing, so it would be a bit too much to blame them all on these palace agents.

In short, after Chen Ze explained the task of the map, this group of palace agents immediately began to get busy, this time they really didn't dare to rest at all, until the next morning when the map was put on Chen Ze's desk, all the palace agents did not close their eyes.

"Shizi, I have verified this map three times, and all the places that were missed before have been filled."

Looking at the map of Qingzhou City, which can almost cover three large tables, it is very detailed, and even some unknown alleys are specially marked.

Glancing at Zhao Ziyun, who had black bags under his eyes, Chen Ze said with his hands behind his back: "Okay, it's hard work, let's go back and rest first!" If there is any news, I will let Mr. Li inform you at that time. ”

"Yes, retire from your duties."

Zhao Ziyun hurriedly retreated, while Chen Ze hurriedly took the map to find Jiang Taigong.

Mrs. Jiang lived in another guest room, but at this time he was still tormented by Chen Ze's question, and it seemed that he hadn't closed his eyes for a day and a night.

Chen Ze couldn't laugh or cry at this, he thought that if Jiang Taigong couldn't figure it out, he wouldn't continue to count it, but he didn't think that he was still struggling with this question!

"Taigong, Taigong?"

Jiang Taigong glanced up at Chen Ze, and after answering without being salty, he lowered his head and continued to think.

"Taigong, don't forget it." Chen Ze persuaded: "The body is important, rest first." ”

"The old man has his own measure."

Chen Ze secretly rolled his eyes, no matter how you look at it, it seems like you have fallen on the bar with this math problem!

"Taigong, the junior of the map has already got it for you, do you want to see it now?"

"Just put it on the table, I'll see."

"Okay."

Chen Ze put the rolled map on the table, and saw that the old man didn't pay attention to it, so he had to say: "Taigong, the matter is urgent, please take a look at it first." ”

"Got it, got it!" Jiang Taigong said a little impatiently: "Why are you so annoying in your later life? I said I'd take a look, and I'll see. ”

"Yes, yes, the juniors are talking too much, so retire."

Chen Ze gave his hand, but as soon as he exited the door, Qin's sister-in-law hurriedly beckoned to Chen Ze.

"Sister-in-law, what's wrong?"

"Brother Chen, Taigong has been counting it for a day and a night, hasn't he calculated it yet?" Sister-in-law Qin smiled bitterly: "Is that arithmetic problem you came up with so difficult?" ”

"It's really hard."

For modern people who have received nine years of compulsory education, it may not be so difficult, especially for those in the third year of high school, it may be solved in a few minutes, but the problem is Dachu, in this problem involves the area of the cone and pi, etc., and you want to calculate it without a formula......

Chen Ze couldn't figure it out anyway.

"Brother Chen, it's not a way to go on like this." Sister-in-law Qin hurriedly said, "Taigong, he didn't even eat breakfast!" His body bones are not very good, and if he continues like this, he will collapse! ”

Chen Ze didn't expect Jiang Taigong to be so shafted!

You have to struggle with a math problem.

"Brother Chen, why don't you tell me the answer?" Sister-in-law Qin secretly said again: "I want to find a way to let the princess know." ”

When Chen Ze heard this, he hurriedly shook his head and said: "No, no, he is stubborn like this, if you tell him the answer at this time, this is equivalent to insulting him for not being able to do it!" When the time comes, I will be emotional, and if I really get a cerebral thrombosis, I will wait for the feast! ”

It's one thing, it's another...... Chen Ze didn't know the answer either.

If he can't count him, the formula has long been forgotten.

"Brother Chen, what should I do?"

"The bell must be tied to the bell." Chen Ze spread his hands helplessly: "That's my question, I want to find a way!" ”

After all, if it goes on like this, Jiang Taigong may not have the heart to look at the map, and Chen Ze still expects Jiang Taigong to come up with advice!

After thinking about it, although he didn't know the formula, Chen Ze could still help provide ideas.

Seeing Qin Jinke playing with mud and pinching clay figures there again, Chen Ze suddenly had a plan.

"Jinke!"

"Huh? Uncle Chen? ”

"Why do you play with mud every day, didn't you buy you toys?"

Qin Jinke was still a little angry at the mention of this matter, and said unhappily: "Uncle Chen, the toys you bought me are only toys for children who wear open crotch pants, why did you buy them for me when I was already past the age of wearing open crotch pants?" Isn't it a joke to take it out? ”

"......" Chen Ze laughed dryly: "I'll make it up to you next time!" Uncle is looking for you to do something now! ”

"What's the matter?"

"I'll pinch a mud now, and you'll take it to your old lady in a while, so that your old lady can see it."

"I knew you wanted to play with me!" Qin Jinke said proudly: "What are you still looking for excuses to do? ”

"Yes, yes, I just want to play with you."

Chen Ze didn't bother to argue, so he hurriedly started to pinch out a model.

The top is a cone, and the bottom is a cylinder.

"Jinke, when you see your old lady later, you will say that if you want to calculate the area of this circle, you must have a pi, otherwise you can't calculate it."

"Uncle told you what is pi...... Chen Ze drew a circle and gestured: "This circle is the circumference, and the horizontal one is the diameter, and it must pass through the center of the circle, and the center of the circle is this point......"

Chen Ze explained that pi is the ratio of circumference to diameter, and this value is about three, so he hurriedly asked Qin Jinke to carry the pinched model into Jiang Taigong's house.

After a while, Qin Jinke ran back with the model.

"What did your old lady say?"

The old lady said she didn't need to remind him. Qin Jinke said: "He knows the circumference, and he also said that Uncle Chen, you can't be sure, the circumference is between three, one, four and five." ”

On the contrary, Chen Ze looked confused.

it!?

Jiang Taigong's pi is so accurate?

"That's not right! Since your old lady knows what the circumference is, why can't he figure it out? You go and ask. ”

Qin Jinke ran back again, and came out again after a while.

"What did the old lady say?"

"The old lady said that arithmetic must be rigorous, he has been calculating for the past two days, and now he has pushed between three and one four-one and three and one four-two, and he will continue to push back ......."

When Chen Ze heard this, his scalp immediately went numb.

"Damn!? Hard calculation of pi!? ”
