"The banks of the Bailu River are rich in water resources, which is convenient for the application of the most advanced magic machinery such as water turbines and steam engines, one hundred and twenty miles to the south of the Great Falls City, two hundred and seventy miles to the north to Krasbourg, and there are direct railways in the north and south, and you can go back and forth within one day, the transportation is very convenient, Your Highness decided to build an industrial zone here is really a wise choice, far-sighted——"

"What do those marks mean?" Roland interrupted Semyon's words, too lazy to listen to him.

Semyon followed his gaze and saw a large number 3 in the center of the field circled by white ash, and another smaller field next to it was marked with the number 2.

"Oh, Your Highness is asking about the venues that are enclosed in white ash, right?" Xie Miao smiled knowingly, "It is all planned to build a factory area, because the factory located in the Karon Industrial Zone can enjoy tax deductions, from Colasbourg to Great Falls City, many large and small industrialists around the area want to rent a piece of land in the industrial zone, some want to move the factory over, some plan to open a branch factory, there are currently more than 40 in total, when signing the contract, I asked them in detail how much the new plant in preparation for construction occupies an area, how much power is needed, and then plan the site according to the intention, The numbers marked in the center of the site are the predetermined plant power, and at the same time as the construction of the plant, it is necessary to order the corresponding power scale of the water turbine from the manufacturer in Baiougang in advance to ensure that the water turbine is in place at the same time as the plant is completed, so as not to delay the start of the new plant. ”

"What do you mean by 'factory power'?" Roland asked Semyon Ivanovich.

"It's a bit complicated to explain...... "Semyon stopped and pointed to the surging White Deer River in the distance, "Your Highness, do you know how much the White Deer River flows in this section of the watershed near Karon Falls and how much power it can provide?" ”

Roland shook his head frankly, "I planned the industrial zone downstream of Karon Falls to take advantage of the abundant water resources in the area, but if you ask me how much power this watershed can provide, I really don't know. ”

"His Royal Highness is only responsible for the overall planning, and of course you don't have to worry about such trivial matters as measuring the flow of water, just leave it to us grassroots civil servants." "After being appointed by the cabinet as the director of the industrial zone, I asked professionals to measure the flow of the river in this vicinity, and a few days ago I took a postal airship to Baiou Harbor, and visited all the factories that produce hydro turbines, and after communicating with local engineers, I learned that the power that different sizes of hydro turbines can provide is also different, which is suitable for factories of different sizes." ”

"The turbine model corresponds to the factory power, so how is the unit of measurement of the factory power defined? For example, how much energy is the power of 1 factory? Roland asked.

"Oh, it's actually quite simple, one plant is equivalent to 30 cubic feet of water falling from a height of 25 feet per second, which is just enough to drive the smallest 'Type 1' turbine, enough to provide enough energy for most craft workshops." Semyon pointed to the site marked with the numbers, "There is a plan to build a sawmill, which requires 2 factory power, and a type 2 water turbine is ordered, and a paper mill is planned next to it, which requires 3 factory grades, and a type 3 water turbine is ordered......"

"It turns out that there are so many doorways, and I didn't come here in vain today, it's really a long insight." After the emotion, Roland asked Semyon another question, "How much factory power does the mint need?" ”

"It takes 5 factory power," perhaps because he never found a chance to talk to Roland, Isaac was a little uneasy, and rushed to answer without waiting for Semyon to speak, "The mint needs to use a large stamping and minting machine, and the water turbine with too little power can't be moved." ”

"As Mr. Isaac said, the mint needs a Type 5 water turbine, and as far as I know, the arsenal that manufactures cannons only needs 8~10 factory power, and the National Mint is the largest factory in the Karon Industrial Zone." Semyon added.

"If you only count this small section of the Bailu River flowing through the industrial zone, how much factory power can be provided in total?" Roland himself felt that this question was a bit tricky, but Semyon Ivanovich, who was wide and fat, gave a precise answer without thinking.

"This section of the Bailu River flows through the industrial zone, calculating factors such as weather and drop that affect the flow, even in the dry season, it can provide at least 750 factories of power, assuming that each factory needs an average of 3 power units, then the entire Karon Industrial Zone can build at least 250 factories, Your Highness, I have made a detailed plan for the land of the industrial zone based on this estimate."

Roland nodded quietly, but his heart was quite shaken. Semyon Ivanovich, a seemingly slippery guy, has a problem with sloppy horses, but it is really impossible to find fault with his business ability, and the old man Zinovi does have the wisdom to select a competent manager for the industrial zone.

Continuing along the river beach, Roland also learned from Semyon about the peculiarities of this section of the river.

"The White Deer River has a large drop in the Great Rapids River Basin, and the river flows quite fast, so it forms a peculiar phenomenon - even in the harsh winter season, the river does not freeze!"

Roland looked at the white waves of the river, and thought back to his poor knowledge of physics, as if it were true—the faster the river flowed, the less likely it was to freeze. This is a godsend for factories on both sides of the river that rely on water power, and can still start production in the winter.

Semyon Ivanovich was again prescient in the chattering praise of His Royal Highness the Prince, and specially chose the section of the river that does not freeze in winter to build an industrial zone.

Roland could only smile bitterly, in fact, he didn't realize this at all, and now it seems that he is just crooked, where is the "no last resort" and "foresight" touted by Semyon.

The river beach was rough and muddy, and the road was very difficult to navigate, and it took Roland and his party nearly an hour to reach the mint. After this journey, the high-end leather shoes of the four gentlemen were almost destroyed. Fortunately, Antron was here, and he used a 0-ring trick "magic trick" to help everyone clean up the mud on their shoes and socks, which somewhat preserved some decency.

Roland and the others came quite coincidentally, just in time to see an airship hovering over the mint, like a wild goose rising in the sky, slowly flying north.

At first, Roland thought it was the "Aurora", but after asking Isaac, he learned that it was actually the "Aurora 2" postal airship, which was the same model as the "Aurora", and sent four new "stamping mints" from Baiou Harbor.
