Chapter 83 Planning
After the Penglai entered Baishi Bend, Liu Xinqi saw that a small wooden pier had been built on the seaside inside Baishi Bend. The pier extended about fifteen feet into the sea. The Penglai barely parked half of its hull on the pier.

The soldiers and the laborers began to unload supplies. Liu Lisheng took Liu Xinqi ashore first and walked towards the leveled land.

Walking two hundred steps in from Baishiwan, about a hundred tents have been set up here. These tents were the tents used on the Liujiabao migration route. They are now set up here to provide for the tribesmen and laborers working in Baishiwan. live.

Since there is no need for quick loading and unloading, the tent is reinforced and a thick layer of straw felt is laid on the outside of the tent for thermal insulation.

Liu Xinqi opened a tent. It was not messy inside. It seemed that the previous military training was still useful.

"After the military training, our collective labor has been under military management, so this tent still looks decent." Liu Lisheng followed and said.

There was an earthen coal-burning stove in the middle of the tent. The fire was being heated with charcoal ash, and some warmth was emanating from the stove.

"When working during the day, I would warm the fire like this, and then light the fire to keep warm when I come back at night." Liu Lisheng explained when Liu Xinqi noticed the carbon stove.

"You must pay attention to ventilation, otherwise you will be poisoned." Liu Xinqi said.

"I understand that lessons have been passed down since ancient times, and the principles of this phenomenon are included in the textbook you compiled, so every tent has a vent at the top." Liu Lisheng said, and pointed upward with his hand.

Liu Xinqi looked above his head. Sure enough, there was a large skylight in the middle of the tent, and a large cover was set three feet above the outside of the skylight. This not only ensured ventilation, but also prevented rain and snow from falling from the middle skylight.

After watching for a while, Liu Xinqi walked out of the tent and walked towards the construction site. Unexpectedly, as soon as he walked into the gap between the two tents, he stepped on a puddle of feces.

"The people living here are all rough men, so..." Liu Lisheng explained awkwardly.

"This won't work. Camp hygiene cannot be guaranteed, and people who live here will get sick very easily." Liu Xinqi said: "On the migration route before, centralized urination and defecation spots were established in the campsites. Now we cannot relax."

"Later, you need to arrange for people to build public toilets and public bathrooms to improve the environmental sanitation and personal hygiene of workers here."

"I will make arrangements soon." Liu Lisheng responded.

"Collecting manure in toilets can not only fertilize the land, but also build nitrate fields to produce nitrate." Liu Xinqi said.

"Are you talking about the 'nitrate' used to make gunpowder?" Liu Lisheng asked.

"Yes."

Then Liu Xinqi explained to Liu Lisheng what saltpeter is.

There are two types of nitrate fields: "Pile manure to make nitrate" and "Urine to make nitrate". The former has few restrictions on raw materials, while the latter only uses urine.

The method of making nitrate in later generations required sealed and high-pressure-resistant jars, and the chemical industry also needed to develop to a certain extent before it could be produced in large quantities.

In ancient times, in addition to mining natural saltpeter, saltpeter could only be made from saltpeter fields.

Use the nitrate field to produce nitrate soil, and then use the nitrate soil to boil the nitrate. "What do you want saltpeter for? You can go to the drugstore to buy it. Why do you have to go to so much trouble?" Liu Lisheng asked in confusion.

"I plan to make a weapon that uses gunpowder to shoot projectiles faster than bows and arrows, farther than bows and arrows, and easier to operate and learn than bows and arrows." Liu Xinqi replied: "As long as there are a large number of these weapons, our Liujiabao will be here In this troubled world, neutrality has been established, and no one can bully it. And making gunpowder requires a lot of saltpeter, and the amount in the pharmacy will definitely not be enough."

"But the pharmacy also needs to buy it. Once things are settled in Baishiwan, I will go back to Laizhou to develop it with Uncle Zhimu. During the development period, a large amount of gunpowder will be needed, and it will definitely be too late to wait for the nitrate field to be manufactured."

"Is this what your ancestors taught you?" Liu Lisheng asked gossiping.

"That's right." Liu Xinqi replied vaguely.

The two came to the leveled land. Currently, they have leveled an open space of one hundred feet long and wide, which is about the same size as Liujiapu in Qizhou.

At this moment, only a small number of people are busy in the flattened space, and the others are busy beside the red stone mountain in the distance, beside a row of fire kilns, and you can see that there are piles of earth bricks piled up like hills, and A small portion of the fire burns the bricks.

"This is too small." Liu Xinqi said.

Then he took out the plan he had made on the boat before.

Liu Xinqi planned to build a small town in Baishiwan this time. The planned town was two miles long and two miles wide, regardless of the inner and outer cities.

The city has a city wall, but due to the development of artillery and other siege weapons in the future, the defensive role of the city wall will become weaker and weaker, so Liu Xinqi does not plan to spend more time on the city wall and only plans to build a simple rammed earth wall.

The outer part of the city wall is made of adobe bricks, and the inner part is filled with soil, and then tamped. Each layer is about half a foot, and the layers are built up one by one. The lower part of the city wall is planned to be one foot wide and two feet high. Because the wall is diagonal, the wall is horizontal. The cross-section is trapezoidal, so the top of the city wall is six feet wide, which is about the width of a strong adult man lying down.Finally, a female wall one foot wide and five feet high was built on the outside of the top of the city wall.

"This city wall is a lot of work. According to your plan of two miles in length and width, the city wall will be eight miles in length. It will probably be enough for all of us to fight for a year." Liu Lisheng said.

"Don't build the city wall first, build houses within the planned city wall first, and then slowly build the city wall after everyone has a house to live in." Liu Xinqi explained, and then continued to describe his plan to Liu Lisheng.

Nine main roads, three vertical and three horizontal, were built inside the city wall, dividing the city into sixteen districts. The doors opened on all four sides, and the north gate faced the sea.Counting from Fangshi in the northeast corner to the west, they are [-]st, [-]nd, [-]rd... and [-]th Fangshi respectively.

Fangshi is divided into residential area (fang) and trading area (city). The second and third fongcities near the north gate are set up as trading areas, namely East City and West City respectively. They will be divided in detail according to different transaction contents in the future.Temples and stages will also be set up in the East and West Markets.

The 36st, 200th, [-]th, [-]th, [-]th, [-]th, [-]th, [-]th, [-]th and [-]th quarters near the city wall are all residential areas. The residential quarters are divided into three horizontal and nine vertical small alleys. There are [-] small squares, which are six feet wide and fifteen feet long. This small square is then divided into five small courtyards (about [-] square meters) three feet wide and six feet long, arranged side by side.

In this way, each courtyard has a front and back door, and both front and back doors lead to alleys. There are a total of 180 small courtyards in Dafang City.

There are a total of [-] small courtyards in the ten residential communities, which can accommodate [-] households. Even if some of the small courtyards are removed, they will be used for other purposes, such as municipal management, small markets in the communities, public bathhouses, etc. Wait, the remaining courtyard is more than enough for all Liujiapu people to use.

The remaining four cities in the middle will be used as workshops, the sixth and seventh cities will be used as workshops, the tenth city will be used as schools and research institutes, and the eleventh city will be the location of various management departments of the city.

Since these four squares are located in the middle, a square with a length of [-] feet and a width of [-] feet must be left at the middle intersection. Therefore, the squares are not regular squares, and one corner is missing towards the middle.
