The water supply system has built a large reservoir outside the city. The water from Hongsha River can not be drunk directly. Although the river was clear in this era, many people drank it directly.

Take water directly from the river. In case of animal carcasses upstream, the drinking water of the whole city will be threatened. One of the purposes of sulun's reservoir is to disinfect.

Pebbles, fine sand and charcoal will be paved in the reservoir to filter the river water. Of course, these can only filter the sundries in the water. Su Lun also prepared a fine screen made of pure silver, which will be filtered through the previous processes and then disinfected with silver screen. After several processes, the water source can be safe.

It took a long time to complete the construction of the water supply system. When the water supply facilities were being built, the caravan from kart came to buy white sugar.

.....

After gene left, Karen city.

Fernander is the leader of the caravan sent by Flamingo chamber of Commerce to zhenbeipu, and is also the largest of the eight chambers of commerce that have come here together. The skylark chamber of commerce that has cooperated with zhenbeipu is also among them, but the scale of skylark chamber of commerce is only the fourth among the eight chambers of Commerce.

In addition to Robert of the skylark chamber of Commerce, there is also an old acquaintance of Su Lun in these chambers of Commerce, Owen, the manager of the Bauhinia caravan. Yes, he is the fat man who was bitten by Su Lun last time.

At the beginning, he came here to dig the foot of the wall. He didn't want to pay any price. As a result, Su Lun and the barbarian warrior dug a hole together. Unexpectedly, he dared to trade this time. Of course, Su Lun will not deliberately pit him. He needs Zhenbei fort to prosper. It's better to do less to pit people. Of course, if someone thinks Su Lun is easy to bully, he doesn't mind playing with these people.

"Mr. fernander, I think we should form an alliance to monopolize the sugar trade here."

"Yes, I think so too. As long as we can monopolize the white sugar trade here, our annual profit can easily double."

"I agree too." other caravan managers agree one after another. They have completely taken the white sugar of Zhenbei castle as their bag.

"Now that everyone agrees to monopolize the sugar trade, we need to divide some shares," Fernand nodded.

Then fernander looked around at the heads of the other seven chambers of Commerce, and said impolitely, "I want 20% of the sugar share, and you can negotiate the remaining 80%."

The other seven chambers of Commerce had no opinion on this. Obviously, this was the norm. The next seven chambers of Commerce began to negotiate and quarrel for a little more share, and the whole scene became very hot. Instead of interrupting, fernander took out a pair of delicate scissors and carefully trimmed his nails.

It was not until the directors of these chambers of Commerce determined the share that they began to speak: "now that the share has been agreed, let's determine the purchase price."

"Robert, what was your last purchase price, Kinnard?"

"Fifty dinars a catty."

"The price is too expensive. We should let him reduce the price!" Owen said as soon as Robert's voice fell.

"Yes, the price is reduced. I think it can only be accepted when it is reduced to at least 35 jinnars." the manager of another caravan also agreed.

"You think of the problem too simply. In order to get a high price, he is likely to prepare an auction." Robert threw cold water on Chris when he knew she was difficult.

"So what? We negotiated the price. If it exceeds this price, we won't shout."

"Yes, that's it."

A group of people agreed.

"What if he doesn't want to sell?" one of them said suddenly.

"Very simply, if he dares to refuse the transaction, let him see the power of our eight chambers of Commerce. I think he will agree." others laughed one after another. As the eight largest chambers of Commerce in kart City, they controlled more than 60% of the trade in kart city. They are qualified to say this.

After discussing the matter, the group held a small banquet, and then went to prepare the caravan to Zhenbei fort.

......

Su Lun didn't know that the eight chambers of Commerce had agreed to monopolize the sugar trade. Of course, even if he knew, he wouldn't care. In his opinion, the alliance of these people is not reliable at all. With only a small external force, the alliance will fall apart.

Eight caravans came to Zhenbei castle. Except Robert, several other caravans were shocked by Zhenbei castle. In their mind, this small territory located in the Northern Wilderness should be inferior to those in the countryside.

As a result, I found that although the town is small, it is extremely clean and tidy. All the roads are paved with stones. There are drainage ditches on both sides of the road. There is no stench of fecal fermentation in the air. All the houses are arranged neatly, which looks like a different kind of beauty.

Everyone was informed of the rules here before entering the town. Many caravan guards and mercenaries found it difficult to accept such cumbersome rules for the first time. The city even had to walk on the right? How old is your little broken town?

As a result, all the caravans agreed after the two barbarian axe warriors directly taught the restless mercenaries a lesson. I can't help it if I don't agree. Who would have thought that two barbarian soldiers killed most of a caravan's dozens of guards and mercenaries.

After knowing the force value of Zhenbei fort, even those caravan managers were honest. After a downfall, the caravan was arranged in the trading market.

Sulun is not very interested in the arrival of the caravan. He is busy building water supply channels. The water supply channels from the river are gradually reduced. The starting point of the river channel is about half a meter lower than the end point of the reservoir. Moreover, the closer to the town, the higher the ground, the less the workload of the water supply canal and the faster the construction speed.

After turning mud into stone, Su Lun rode a black maned horse to the tavern. During this time, he would sit in the tavern every day. After all, the properties of the tavern said, is it possible to attract some heroes here? He's just going to try his luck in the tavern. If he meets a hero, he'll make money.

After arriving at the tavern, Su Lun found that today's tavern is very busy. The tavern that can accommodate 80 or 90 people is actually full. Fortunately, the bar is a three-story building, and there are many vacancies on the second floor.

Su Lun ordered a cup of rum, then found a corner and began to observe the guests in the tavern. To his disappointment, although there were many people in the tavern today, these people didn't find any special people except guards and mercenaries.

These mercenaries like rum very much. Although the price is twice as expensive as wheat wine, it is still very popular. It seems that rum can also sell at a good price.
