Unlike Cang, Fatzitun was not interested in carpentry skills, but in knowledge of arithmetic and physics.
The reason why Fatty Tun was assigned to the artillery division was not because he knew carpentry, but because he knew magic.
He calculates all the wood and stone needed by the gunners, as well as how many trebuchets can be produced.
It is said that this is a skill that Fatty Tun learned from his father doing business since he was a child.
This is exactly what Shen Bing wants.
Because if Fatty Tun was interested in carpentry skills, Shen Bing wouldn't be able to teach him.
Taking advantage of his free time, Fatty Tun moved a folding stool to sit next to Shen Bing, took out a piece of sheepskin from his arms and asked carefully:
"master."
"These weird symbols you drew, I understand the rest."
"It's just that this circle... I really don't know what it means."
"Please give me some advice, master."
When Shen Bing took a look at the sheepskin, he couldn't help but say "Hey".
That was exactly what Shen Bing had done on the ground to calculate whether the trebuchet could throw linen bombs into the city.
I don’t want this Fatty Tun to copy it word for word.
Another thing that surprised Shen Bing was...this guy actually said that he already understood these numbers?
Although it is not difficult to understand these Arabic numerals, it is not easy if the drafts are arranged like ghost symbols and have to be calculated back.
"Do you really understand?" Shen Bing asked without answering.
Fatty Tun touched his head in embarrassment and replied:
"The disciple saw that the master was busy, so he didn't dare to ask more questions."
"I guessed at this picture for several nights."
"Guessing around, I secretly thought that the vertical one should be one, and the curved one should be two."
"And this should be three..."
This surprised Shen Bing secretly:
Yes, I guessed everything from one to nine correctly. It seems that I have put in some effort.
After finishing speaking one by one, Fatty Tun asked with uncertain eyes:
"master."
"I wonder if my disciple's guess is correct or not?"
Shen Bing nodded in affirmation.
Fatty immediately became excited and asked:
"But why can't I see Ten?"
"At first I thought this circle was ten, but if it was ten, the calculation would be wrong."
"Also, what do these symbols mean?"
…
Fatzitun is talking about arithmetic symbols.
In fact, he has roughly guessed "addition, subtraction and multiplication" from the changes in numbers, but he cannot understand division.
It’s no wonder that in this era, the three operations of addition, subtraction, and multiplication are relatively common.
Among the unearthed cultural relics of the Qin Dynasty is a quite complete multiplication table, which is more than 600 years earlier than the West.
It's just that the division methods in this era were relatively simple, such as "two and a half make one" and "four and a half make two."
Moreover, since the dividend is large and there are abdication and remainder, Fatty Tun will not be able to guess it.
So Shen Bing explained to Fat Zitun the so-called "circle" (0), and then talked about the four calculation rules of addition, subtraction, multiplication and division.
I don't want this fat guy to be able to explain everything at once.
While listening, he nodded and said in a shocked tone:
"That's right!"
"How can...it be calculated like this?"
"It is indeed possible, and the calculated results are exactly right!"
…
After some calculations, Fatty Tun said excitedly:
"This algorithm is much more convenient than the algorithm I'm waiting for."
“Not only is it accurate, but it’s also much faster.”
"Thank you, Master, for your teaching!"
After saying that, he excitedly gave Shen Bing a big salute.
This may be nothing to Shen Bing, it is just basic knowledge in modern times.
But it opened a door to Fatty Tun, a brand new world of computing.
From then on, Pangzitun could easily solve calculations that seemed impossible to others by just arranging some drafts.
These are small things.
Originally, the final battle of Qin destroying Zhao could continue like this.
After all, the war situation has been decided, and the Qin army only needs to wait a few months, and it will be over when Handan runs out of food.
But some people are not willing to play like this.
In Xianyang Palace, King Qin Yingzheng walked anxiously around the palace, and all the civil and military officials did not dare to say a word.
Before Li Mu died, Ying Zheng was not so impatient.
Because it was still unknown to destroy Zhao at that time, and judging from the battlefield situation, most of them would return without success as before.
But now that Li Mu was dead and 200,000 Qin troops surrounded Handan, Ying Zheng could no longer sit still.
If there is any country among the Six Kingdoms that Ying Zheng wants to destroy the most, it is definitely Zhao.
This is not because of Zhao's important strategic position, nor because Zhao's army has superior combat power to Qin's army.
What's more important is that Zhao Guo is humiliation, stain and torture to Ying Zheng.
Ying Zheng couldn't wait to erase it from the map, just like erasing those unbearable past events.
Now that the destruction of Zhao is imminent, how could Ying Zheng agree to let Wang Jian take his time?
After walking for a while, Ying Zheng suddenly stopped and asked sharply:
"Li Mu is dead and the morale of the Zhao army is low. This is a great opportunity to destroy Zhao! Why doesn't Wang Jian attack?"
"Is it possible that I am already old and have more ambition than strength?"
Li Si knelt down and replied:
"Your Majesty."
"Although the morale of the Zhao army is low, Handan is still capable of fighting."
"A strong attack will only result in loss of troops and casualties."
"The best strategy is to besiege rather than attack. We just have to wait for Handan to run out of food..."
Anyone with a discerning eye will know that the correct approach is to "encircle but not attack" at this time.
In particular, Zhao State had experienced earthquakes and droughts before, and the city of Handan did not have enough food to last long.
But Ying Zheng even had the manpower ready to build the Zhao Palace...
Ying Zheng had a hobby: "Every time he destroys a prince, he writes and releases his palace."
That is to say, every time a country was destroyed, the emperor built a replica of that country's palace in Xianyang Palace.
And he was most impatient for Zhao Guo, so how could he listen to these words.
Ying Zheng waved his hand to interrupt Li Si and said:
"It may change later."
"How can we know whether Chu, Wei and other countries will send troops to help!"
There is some truth to this concern.
Because this has happened before:
The Zhao State suffered 400,000 deaths due to the Battle of Changping. The Qin army took advantage of the victory and pursued it and was about to destroy Zhao.
However, Lord Xinling of Wei State came to save Zhao State by stealing a talisman and averting Zhao State's crisis.
The current situation is similar to that of that time. It is difficult to guarantee that any country will understand the principle of "a lip is dead and a tooth is cold" and will bring troops to help.
However, this is actually just an excuse made by Ying Zheng.
This time, that time.
Not to mention that it is not easy for other countries to protect themselves now that their national strength has declined, how can they save Zhao?
Moreover, with the death of Li Mu, the State of Zhao ceased to exist in name only, and it was impossible to save it even if it wanted to.
But Li Si said nothing more, because he knew that Ying Zheng had already made up his mind and it would be useless to say more.
Sure enough, the next moment Ying Zheng ordered:
"Someone is coming!"
"Eight hundred miles urgent!"
"I ordered Wang Jian to attack Handan as soon as he received the letter. He must not disobey the order."
The messenger followed the order and left.
This was not the end yet. After retreating from the court, Ying Zheng was still restless in his bedroom.
Whether you are sitting or lying down, scenes of Handan's past will flash in your mind.
In the end, Ying Zheng couldn't bear the torture anymore, so he ordered Zhao Gao, who was standing by to wait on him:
