When they came to the lake again, Luo Yunyan whispered to Xi Pei, "With my skills, I should be able to handle three or five of them. Just follow me. Although this guy looks good, I can't guarantee who he is."
Wang Xipei smiled with her eyes curved when she heard this and leaned closer to Luo Yunyan.
The three of them went into the water and witnessed the strange whirlpool. When the young man came out of the water, he took a branch and drew on the ground. Xi Pei was curious and went over to take a look. It seemed that he was calculating something.
The young man explained to Wang Xipei, "I threw two stones weighing one jin and five jin. From the different distances they bounced off, we can estimate how much force would be applied if we ourselves wanted to enter.
"I think only speed can break this force." The young man pointed to the location of the second waterfall. "Use two large bamboos, bend them into a bow, and send the three of us out like arrows at the right angle... Once we gain speed, we should be able to rush into the vortex and see what happens."
Luo Yunyan asked, "Do you need help?"
The man said, "We need fifteen people and tools."
Luo Yunyan mobilized people from the Gu tribe and collected the necessary tools from Ye Zhou and Prefect Yun Zhao.
This man led fifteen people to start working, and he seemed confident and methodical.
Wang Xipei looked at him and said he was in business, but... suddenly asked, "May I ask your name, sir?"
The man hesitated for a moment, and finally said, "Jiang Tao."
Wang Xipei listened and agreed, then asked, "Excuse me, who is your lordship, the world-famous hydraulic master Jiang Yan?"
The young man could only bow and say, "Father."
This young man was Jiang Tao, the third son of Jiang Yan. Jiang Tao's talent for algorithms had been revealed to everyone in an astonishing manner since he was young.
When Xuanyuan Hao was building the four major granaries at Tai, Bian, Hu, and Guang, the ministers of the Ministry of Works argued endlessly over the location of the four granaries. Jiang Tao, who was about eight or nine years old at the time, was taken by his grandfather to visit his former colleagues in the Ministry of Works.
The two old men were chatting and mentioned that Xuanyuan Hao had set a time limit for the completion of the four major warehouses, but the people in the Ministry of Works were arguing over the site selection.
The location was wrong and the inconvenience was discovered after use. Your Majesty will definitely blame the Ministry of Works for its incompetence.
But you will still be scolded if you fail to complete the work within the specified time.
Xiao Jiangtao listened to them and based on the grain storage capacity of the four major warehouses they mentioned, the differences in grain production and use, transportation capacity, required area and manpower, he roughly selected four addresses through his calculations.
Then little Jiang Tao told the two grandfathers everything. They didn’t understand, but they felt it was impressive and took him to the Ministry of Industry.
At first, no one took eight or nine-year-old Jiang Tao seriously until he started calculating on the spot.
There were many pure technical experts in the Ministry of Industry, and they immediately realized that the young man was not talking nonsense. Not only could he really calculate and use the algorithm accurately, but he also did it at an astonishing and incredible speed.
The Minister of Works tested Jiang Tao with a previous calculation by a large number of people from the Ministry of Works. Eight people had spent a month calculating the data, while Jiang Tao spent less than an hour, achieving the same result. Young Jiang Tao said their method was too time-consuming; it should have taken them only half a month at most.
The Minister of Works acted decisively. The data discussed by the two old men was extremely rough, so he asked someone to bring a large amount of accurate relevant data, even including meteorological data from various grain collection and transportation areas, to Jiang Tao.
Xiao Jiangtao asked a question: "After the granary is built, what are the ten most important requirements that need to be met? Please rank them for me and distribute the number of one hundred to these ten requirements in order of importance."
The technical experts in the Ministry of Industry understood and explained it to the Minister of Industry. When the Minister of Industry heard that he could not make the decision, he reported to Xuanyuan Hao.
After Xuanyuan Hao understood what it meant, he became interested. After the ten requirements, he marked fifty, thirty, ten, five, three, and several other different numbers, and crossed out three requirements.
The Ministry of Works received the order and gave it to Jiang Tao. Jiang Tao looked at the request and told the people in the Ministry of Works that a small part of the information could be moved away and no longer needed to be considered, and then began to calculate.
Xuanyuan Hao frequently visited Jiang Tao throughout the day to see him calculate. He had originally intended to have the Ministry of Works recalculate the same number of times, but he found no one could keep up with the boy.
So he said, "This young man is a genius, and ordinary people can hardly compare to him. Let's just check three or four small details."
Jiang Tao calculated for a day and selected four best addresses.
The Ministry of Industry only reviewed the calculation results of three small parts, and it took all the manpower to calculate for eight days.
The worker sighed, "It's like butchering an ox like Ding." Mathematical problems for Jiang Tao are like an ox lying in front of him, his skin, flesh, tendons, bones, and internal organs clearly visible. He can take whatever he wants as easily as taking something out of a bag. His natural talent for calculations is nothing more than a sharp blade in his hand. His greatest strength lies in his knowledge of calculations, which he masters like a fish in water.
For us, it is just like the blind men groping in the fog of difficulty.
Xuanyuan Hao liked this young man very much and intended to make an exception to keep him in the Ministry of Works, but when he asked Jiang Tao, he found out that he was interested in water conservancy because of his father's name.
Xuanyuan Hao thought that was a good idea. With the guidance of his grandfather and father, another great master would emerge in the future.
So the child was taken back by his grandfather, but little Jiang Tao, who was not yet nine years old, was given a nominal position in the Ministry of Works with Xuanyuan Hao's approval and received a monthly salary.
The Ministry of Works saw that this was a colleague. A colleague who could calculate quickly and accurately was very useful. For a period of time, people from the Ministry of Works came to see Xiao Jiangtao every day. Xiao Jiangtao calculated for them and found their mistakes every day.
It wasn't until Xuanyuan Hao found out and called the Minister of Works to scold him that the situation finally subsided. After being scolded, the Minister of Works established a rule in the Ministry of Works that anyone who wanted to settle accounts with Jiang Tao had to first get approval from him, the Minister of Works.
