After drawing on the map, Yao Ran pointed to the map in the notebook and said, "Look, this is a triangular city, and this is a square city. The pen "Fun" Pavilion www.biquge.info their area is nearly doubled. ”

After finishing speaking, Yao Ran was silent and handed the leather notebook in his hand to Yao Huo. Yao Huo took Yao Ran's notebook and looked at it carefully, sometimes gesturing with his hand on the map.

After looking at Yao Huo for a long time, he said, "Is it made in a circle, is the city area large?" The curious Yao Huo watched it for a long time.

Yao Ran nodded in surprise and said, "Compared to the situation, the same city wall has a larger circular area. Yao Huo is indeed very smart, such a later life has been proven to come to a positive conclusion, he looked at it for a while and guessed a positive answer.

Looking at Yao Huo as if he was looking at his own child, Yao Ran was very satisfied, thought for a while and began to explain to Yao Huo in detail,

In fact, with the same length of the city wall, the area of a circular city is indeed larger than that of a square city, but the naturalization of a round city is not as simple and straightforward as that of a square city. There is not much difference in size, and the square old city wall will be easier to plan for future expansions.

Moreover, if the round city wall is definitely more difficult to build than to make a square city wall, with the current city wall, you only need to cut down the forest behind it, and then build it in the same place.

Then use their simple frame method to fill directly into the middle of the foundation and the pile, and it is easy to build the foundation of the city wall, and the outside of the green bricks can slowly continue to supplement the construction.

This method is simple and convenient, but the firmness is not so good, but the outer city wall is stronger than nothing, if you really want to carry out secondary reinforcement, you can expand on the basis of the original city wall.

Yao Ran made various explanations in the car, Yao Huo listened carefully on the side, and it didn't take long for Yao Ran's entire convoy to arrive, this special small city on the edge of Yao Zhai, which is located on the traffic artery of Yao Zhai and the city to the south, and what really needs to be dike is actually the direction to the south.

That is, one of the directions of the most populous and concentrated area of goods in Yao Ran's territory, if you count the salt lake fortress, there are five strongholds and five cities in the south and up of the blast furnace camp.

But why is it said that the blast furnace camp is mainly guarded against in the south, because although the five cities in the south can not watch each other, but in fact the forest is dense, and it will take a long time for the defense between cities to be established. So if someone, or a beast, infiltrates the forest and crosses to attack the blast furnace camp, it is more suitable to attack the blast furnace camp.

Therefore, the safety of the blast furnace camp is both in terms of terrain and its own importance, as the cradle of the most advanced technology of the whole Yao Ran, as the origin of steel, there is an endless stream of vehicles coming and going, mainly to transport iron ore and other corresponding materials.

In the blast furnace camp, Yao Ran finally saw the businessmen on his feet, and a large number of convoys, the headquarters of the blast furnace camp produces steel, and the gate of the Emperor of the Public Security Road Yin is made of pure iron, which seems to have the most weight of a thousand miles.

As soon as Yao Ran arrived in this Shun City, Xiaoping had already brought more than a dozen people to stand at the gate of the city gate and wait for Yao Ran's arrival

After adding noodles, Yao Ran hugged his disciple lightly, and then Yao Ran didn't talk nonsense, Yao Ran also has his own palace in the high campsite, Yao Ran now has eleven strongholds under his name, and all Yao Ran's palaces have been built at this moment, that is to say, Yao Ran brought his wife, and it was very comfortable to sleep there.

After getting out of the car, Yao Ran didn't talk nonsense, and didn't say anything to Xiaoping, he walked straight in the direction of the blast furnace, no matter whether the blast furnace was here or in Yao Village, he was the tallest building at present.

Yao Ran hurried over to check whether the steam engine of the external combustion engine could operate normally. How much horsepower can be achieved.

Yao Ran walked fast, although he was fatter, but he was better than his long legs, fat and strong, and the apprentices behind him hurriedly trotted behind Yao Ran to chase after him.

The appearance of the blast furnace camp has changed dramatically, and the original small open-air sheds are gone, replaced by huge steel frames with huge shelves, and the roof is filled with whole ceramic panels, which are more insulated than the grass huts of the past, and can also be more effective in preventing fire. It's just that the whole sheet is too thin and easy to break, too thick and wastes raw materials, so the number of production is not very large.

It is only used in some places where stoves are commonly used, a huge blacksmith's shed, which is like a honeycomb, arranged one compartment after another, each compartment has a huge vent to the outside, and there is also a fan blade for exhaust at the back of the room to use air circulation.

This huge blacksmith's workshop can accommodate forty blacksmiths at the same time, and twenty other sheds can be used at the same time, and with the apprentices carried by the blacksmith door, a total of about sixty people can be used at the same time. The pipe has an exhaust window and exhaust port. But the temperature inside the blacksmith's shack will still be very high and hot.

It was morning, and the blacksmith's shed was bustling with banging, and there was another one that didn't even have a wall around it. There was only one big shed, and everything that looked like a stove, and something like a huge pot was set on it, and something like a propeller had something like a shovel above and below that could be placed in the cauldron below.

Above the rotor vane there is a push rod, in the position of the eccentric shaft. Push back and forth to push the rod, and you can stir-fry the contents of the cauldron below.

And what is being stir-fried in the cauldron below at the moment is not a delicacy, and a pot full of iron sand is fried iron. In the past, it was just fried in a pan with a small spatula. Now, after various design semi-mechanization improvements, a lot of work has been optimized, but because of the power, only human labor can be used to complete these physically demanding tasks.

Of course, this kind of dirty and tiring work, no one likes to do, it is all done by slaves, and the slaves are all hard workers for a few months after they come here, and there is no other reason because of good food.

And over time, the slaves persevered, because it had become a habit, and only a few people felt that their work was not fair.
