Presumably, the yin owl man that Xia Lin saw yesterday was the permanent staff set up by the Northern Military in the imperial capital.

Seeing Harper walking out of the station in a cold sweat, Xia Lin knew that Harper had also met the soldier who seemed to be a little disabled yesterday, and he shook his head speechlessly.

It seems that his friend's psychological quality is not too good, which is not good, after all, he still has a lot of affairs to deal with later.

"Xia Lin, what are we going to do next?"

Harper, who had finally come to his senses, looked at the northern military garrison not far away, and asked Xia Lin.

"Accompany me to the North End to buy a house to settle my family, and then go to the market to look for some lucrative business to support our magical research."

Xia Lin concisely explained the next itinerary, and finally asked:

"Harper, do you know where to find the property?"

"Buying a house, yes? I want to think about it...... Then we should go to the Adventurer's Guild. ”

Harper pondered for a moment, and named a place that made Xia Lin feel a little puzzled, in fact, he had thought that Harper would take him to someone similar to a real estate agent in his previous life to see the house.

He doesn't have access to this, but kids like Harper, who grew up in Midland, should know a lot of people who do it.

"Aren't adventurers' guilds all places to post quests for hiring adventurers? Where can I buy a house? ”

"Of course, I remember that the Adventurers' Guild had a board where trading information was posted, and for a single silver mar, all kinds of sales and purchases could be posted.

A lot of people will post their homes for sale there. If you look for those hateful intermediary merchants, the intermediary fee will be a lot of silver mar. ”

Harper patiently explained when he saw that Xia Lin seemed to regard the Adventurers' Guild as the terrifying existence of adventure stories played by bards on the street that was only associated with the feat of slaying dragons.

"I see, then let's go and see!"

Xia Lin nodded thoughtfully, he didn't expect that there were already people in this world who realized the role of traffic, and even tried to use it.

Sure enough, there are smart people in any era, but in a world where the illiteracy rate is more than 90 percent, Xia Lin is quite skeptical about how useful those advertisements can be.

When they arrived near the Adventurer's Guild in the central area of the Imperial Capital, the people around them seemed to be much more full of martial virtues, and there were basically seven or eight adventurers with weapons wrapped in cloth on their backs among ten pedestrians.

Seeing two rare mages appear in such a place, and the deputy head of a large mercenary group claiming to be the Wind Wolf Mercenary Group came to try to recruit the two of them, he looked very sorry after being rejected by the two.

Xia Lin found the notice board standing outside the Adventurer's Guild, and found that there was indeed a lot of trading information written in charcoal on the plastered surface on it.

He and Harper searched together, and when they saw the news of the sale of the house in the North End, they wrote down the contact address on the parchment they had brought with him, and prepared to look at them one by one later.

However, there are not many houses for sale in the North District, and there are only four houses for two people looking for on the notice board.

Xia Lin felt that Harper alone was enough to deal with it, and in order to increase efficiency and exercise Harper, Xia Lin simply gave Harper five gold lunds and asked him to go over and buy a suitable house for him alone.

In order to buy a house that meets his heart, Xia Lin roughly explained his requirements to Harper:

First, it is necessary to have at least two floors, and it is better to have a yard, but it is not possible to combine one floor and a yard, so that he can have enough space for his next small workshop production.

The second is that there should be more rooms, Xia Lin's family of five people must have at least four rooms to be convenient, Xia Lin doesn't want to live with his eldest brother who will snore that night.

Mage meditation is the most taboo from outside interference, so even the academy's non-commissioned officer dormitory is a narrow single room, and the wooden doors and walls are specially made quite thick for sound insulation.

Of course, if the mage's mental power and concentration are strong enough, it is not impossible to meditate in a noisy environment, but the efficiency will be reduced a lot.

As for the rest, it would be great if he could buy the matching furniture with a small amount of money, and Xia Lin can't spare the time and budget to match the house with new furniture one by one.

Xia Lin himself went to the market to see what raw materials could be found, what the cost of various raw materials was, and what to use to make some research funds next.

After agreeing on a meeting place with Harper, Charlin arrives at Hema Market, the largest market in the Central District.

Although the scale of this market is not as large as that of the dock markets in the southern and northern districts, the convenient transportation allowed most of the guilds and chambers of commerce in the imperial capital to set up a base here to distribute goods in the central and western districts.

These strongholds are connected to each other, and the result is a huge Hema Market that covers three or four blocks.

In the face of such a huge market, if you have no clue, I am afraid that you will not be able to find what you need after looking for half a day.

Xia Lin naturally wouldn't waste time so aimlessly, as early as when formulating plans B, C, and D, he had already set a general goal.

The dye industry is one of the origins of modern chemistry in the previous life, according to Xia Lin's knowledge of chemical history, in the era of natural dyes, if you want to make the dyeing of cloth bright and uniform, and the water cannot be washed off, you need the role of mordant.

Among the commonly used mordants are alum, saponum, bile alum, etc., and these minerals are the target of Xia Lin.

Needless to say, herbal medicine shops.

The Sassen Empire is located in the south of the continent, the climate is humid and hot, and the terrain in the south is mostly swampy and dense forests.

Herbal medicine is a new medical system established by doctors who have absorbed the potion system of witch doctors and the potion system of alchemists for hundreds of years, and in it, there should be some rare animal, plant and mineral ingredients.

As for the stone shop, Xia Lin only uses quicklime, a raw material widely used in the chemical industry.

The grain store is trying to find out the price of the cheapest oils and soybeans, and see if they can try to produce soap, a must-have money-making commodity for travelers.

Originally, Xia Lin was just hoping to be satisfied with finding a few raw materials he needed here, but after going around according to the plan in the huge market, Xia Lin's harvest was even greater than he expected.

Alum, alum, alum, miscanthus salt, lime, diatomaceous earth, sulfur, saltpeter, these chemical basic raw materials, he has found a stable supply channel from the corresponding stores.

Although sulfur and saltpeter are used by physicians as small doses, and herbalists have very limited sources, they are a definite source of sulfuric acid and nitric acid.

And even if there are only the first six chemical raw materials, Xia Lin can already play a lot of flowers.

Not to mention anything else, with diatomaceous earth, a natural adsorbent, Xia Lin can easily obtain a clear sugar solution as long as he buys brown sugar in bulk, and then adds diatomaceous earth to the brown sugar solution, and then he can get white sugar.

Adding soybean milk to the white sugar solution can also obtain crystal clear rock sugar after a series of processes. And these two things, in this era, obviously mean huge profits.

After an afternoon of data gathering and market research, Xia Lin left Hema Market with this key information contentedly, and after meeting with Harper, he got another piece of good news.

There is a seller who is in urgent need of funds to fill the shortfall in his business because the maritime trading ship he invested in the port of Dafa has capsized in a storm, and the asking price of a standard two-story house of almost 60 square meters is only four gold lundes.

You must know that the average price of houses in the North District is at least five gold lundes, and Harper decisively finalized the intention to buy it the moment he heard the seller's offer.

However, out of a responsible attitude, Harper still haggled a little, and finally bought the house for 3 gold and 50 silver mar on the condition that it included all the contents of the house.

After getting the title deed, the house deed and the rest of the money from Harper, Xia Lin couldn't wait to go to his new home with Harper.

And this house, located in the seventh building on the north side of Silverfish Street on the west side of the North District, is also very satisfying to Xia Lin.

The first floor has a kitchen, dining room, vestibule and small toilet, and the second floor is separated by a corridor with two rows of four rooms, and there is an attic above which you can store miscellaneous items, and even a large pile of old furniture.

These include two sets of tables and chairs and various kitchen utensils on the first floor, two commodes in the small toilet, wooden beds and some bamboo baskets for the four bedrooms on the second floor, as well as wooden boxes and shelves.

Looking at the house, which could almost be called a bag to move into, Xia Lin decided to take his parents and siblings from the slum tomorrow.

Then we are going to start a business of making white sugar, and if possible, we will also make some refined salt, and use the brine filtered out of the coarse salt to prepare the raw materials for the next plan.

In order to thank Harper, after seeing the condition of the house, Xia Lin did not hesitate to give Harper a bonus of ten silver mar.

He then invited Harper to a nearby restaurant for a seafood risotto worth thirty copper pes, and gave him a half-day off tomorrow morning.

After sending off the contented Harper, Charlin returned to the house he had just bought, lit two candles for lighting, and sat at the dining table on the first floor in the dim light to plan the production of sugar, refined salt, and soap.

The source of raw materials, the manpower required, the size and quantity of containers for boiling sugar and salt, the source of charcoal fuel, the source of water for dissolving materials, and all other factors must be clearly planned.

The drawings of the simple centrifuges and filtration devices that need to be built, Xia Lin also has to draw.

While making the plan, Xia Lin looked up at the layout of the kitchen on the first floor, thinking that he would probably have to hire stonemasons and carpenters to expand the number of stoves and make fire prevention measures.

On the first floor of 60 square meters, there should be no problem in planning a workshop area of 30 or 40 square meters, and after adding a partition wall, the front hall can also be transformed into a façade for the future sale of sugar, rock sugar, refined salt and other goods.

However, when you make money later, you still have to consider buying a manor outside the city, which is convenient for secrecy, and there is enough land to accommodate the various factories needed in the future.
