Distant Ding tribe, Ding Qi is accompanied by Ben and Yan with torches to check the processing of stones.

Yan Zheng and the people of the original graystone tribe are working on a batch of stones, which are carried out under the direction of Ding Qi, and this batch of stones is mainly used as sewer baffles.

On both sides of the avenue, two drainage and sewage channels were dug according to the plan for the discharge of domestic sewage and natural precipitation, and special personnel were arranged to be responsible for collection and treatment of defecation. Just like in ancient times, there was a profession called night incense worker or honey picker, which was specialized in cleaning up feces "business". It is important to note here that this is the business, because the night incense workers collect the manure and send it to a specific place for processing, and then sell it to farmers who need it for a fee.

Naturally, such people are needed in Tinch's city, but they are done by slaves, and they are not called night incense workers, but sewage workers. These sewers are responsible for the entire city's drainage, not only human waste, but also sewage, animal waste, slaughtered animals, and sometimes sewer blockages.

And now Ding Qi is looking at a batch of stone slabs that he arranged for them to process, which are being processed in a mountain in the middle of the tin and limestone mines, and now Ding Qi is looking at a dozen samples that have been transported down from the mountain.

These dozen or so stones are all processed uniformly according to the measuring stick made by Ding Qi. It is 80 centimeters long, 40 centimeters wide, and 10 centimeters thick, and it is covered with small chisel marks with potholes, which are very rough, but they are all square, angular and angular, and they are all made according to the standard.

Ding Qi tested the strength of the stone slab, easily lifted the nearly two-hundred-pound stone with both hands, and then threw it on the ground in front of him.

Boom!

The slate fell down, smashing a large hole into the ground, but it did not change in itself. He put the slate between the two stones, and let Ben and Yan step on it, but they didn't see the slate breaking.

"Well, it's good, it's sturdy, it's been hard for you all this time. How many of these slabs have been processed now? ”

Ding Qi patted the stone, felt the strength of the stone slab feeding back to him, and looked up to Yan and asked.

"Chief, nearly three hundred of these slabs have been processed now, according to the current progress, one person processes one slate a day, forty stonemasons, to process two thousand five hundred slates, it still needs to, um... Let me do the math. ”

Iwa has been in the tribe for so long, and he has mastered basic math*operations, and he can also calculate addition, subtraction, multiplication, and division. Now the whole tribe has popularized the education of the second grade of primary school, and even the Qiang and Ren tribes have learned this knowledge in the evening.

"Well, it's worked out, and it will take another 55 days."

Ding Qi nodded, frowning slightly, as if 55 days was a bit too long.

"Well, 55 days, this time is a bit long, I'm afraid I can't catch up with the progress of the whole project. In this way, now that the people have moved to the construction of residential houses in the city, you can send some more people to help you. I'll double your manpower, but you'll also be more efficient at gathering and processing stones.

The speed of processing the slate per day has been increased to one and a half, so that all the slate can be laid down to the sewer in half a month, Ben, and the deployment of manpower will be coordinated by you, and the arrangement will be in place tomorrow morning, including the tools they use. ”

Ben nodded and hurriedly responded, and he had already begun to think about where to coordinate the passage of people.

The sewers of the two main roads should be dug and built in advance, so that the operation of the whole city can be more harmonious and clean, and the level of hygiene can be greatly improved.

In addition to sewers and sewers, twenty public toilets were built throughout the city, large and small, mainly concentrated in residential areas and artisans

districts and barracks, on both sides of the main road there are also a number of toilets for pedestrians and outsiders. Each toilet has a sewer who is responsible for cleaning and ensuring that the toilet is clean and hygienic.

After arranging the slate, Ding Qi took Ben and Yan back to his cabin and prepared to eat. Ding Qi has been busy, sometimes he can't even take care of eating, every time as long as Mei doesn't see Ding Qi go to eat, she will arrange someone to send Ding Qi over alone. I don't count eating a small stove, because the meat and broth sent over are made in the cafeteria, and they are the same as everyone else.

Today, Ben negotiated with the canteen in advance, and they delivered the food for three to the cabin. Because after the meeting, a coordination meeting will be held, mainly on the issue of matching the progress of the construction in the city with the bricks, lime and charcoal fired by the ash kiln and the cave kiln.

These tasks are linked one by one, and any link that goes wrong will affect the progress of the internal construction of the entire city.

But Tinch didn't think there was anything wrong with it.

It is unreasonable to say that all four walls were built with the efforts of everyone, but there were problems in the internal construction. Therefore, Ding Qi does not take this as a matter at all, it is nothing more than a matter of balance in resource allocation.

It's just that the principals involved in several aspects have not yet risen to the level of overall planning, and will only do a good job of the work at hand or the work arranged, and will not think about how much it would be more appropriate. In other words, I can't grasp that degree.

Ding Qi was very lucky, glad that he was able to have so many clansmen who could be uniformly deployed. Everyone is very simple-minded, and the goal is the same, as long as it is a word from the leader, they will work hard to achieve the goal.

In order to accomplish something, Ding Qi can unify everyone as a whole and use collective strength to accomplish it. However, it is also necessary to carry out overall planning, otherwise it may waste manpower, materials, and time, and may hinder the achievement of the goal.

After eating and solving the problems of the coordination meeting, Ding Qi held a bedtime communication meeting with the Bucks and Ben, mainly to help the Bucks and Ben solve some problems or difficulties during the day. This can be regarded as a convenience for the two of them, who let the two of them live in a wooden house with the leader!

Of course, these questions are also asked by the two of them at any time, and Ding Qi answers them at any time, and sometimes they are solved during small talk.

No, tonight's bedtime meeting was also mentioned by the Bucks after they came back from outside. The three of them chatted while washing their feet, and they were also very casual.

"Shhh Ha~, it's so comfortable! By the way, Chief, it's no wonder that the cafeteria has been throwing things out lately, mainly meat, especially the meat stewed in the pot for the next day's breakfast. We suspected that a tribesman was hungry at night, so we sneaked over and got some to eat. ”

The stag taps his feet twice in the clay pot and then puts his feet in whole, feeling the comfort of the hot water stimulating the soles of his feet. While rubbing his feet around, he told Ding Qi a strange thing that had happened in the past two days.

"I looked into it and didn't find anything out of the ordinary. He also arranged for people to be on duty there at night, but no one was found to have passed, but the food was still lost. The other tribes reported that no one went out at night, and that there was no light or campfire at night, let alone the cafeteria. The fire was buried under the ashes, and there was no light, and it was black and rumbling that could not see anything. Now everyone wonders if some animal used to secretly eat the food. It's weird! ”

The buck is responsible for the entire defense of the tribe, like the previous investigation of the blind well of the Baipu tribe, he is the main one, and this loss of things is naturally responsible for him.

Ding Qi glanced at the little cutie sleeping on the animal skin cushion next to him, and reached out to stroke it fiercely. This made the cutie very dissatisfied, direct

Roll over to expose your belly and let Tinch tickle it.

After a quick scratch twice to cope with the errand, Ding Qi turned his head to look at Xiao Jin sleeping on the scaffold, and then said to the buck:

"Could it be that Xiong Da and Xiong Er have nothing to do at night to steal food and eat, I remember that these two goods often go out at night! Also, did you send the little cutie over to be on duty for two days to see, it's clever! ”

Ben, who was there with his hands in the basin and his feet buckled, heard Ding Qi say this, and laughed:

"Hehe, Elder Stag is inviting a little cutie, but this thing is just because it's too clever and recognizes people! It used to be better, and it will help you with some food and teasing. But this trick hasn't worked recently, except for what you say, no one else listens, could it be that it's * spring? ”

Ben talked to the end, but he lowered his voice, for fear that the little cutie would hear it, and ask her doubts.

Ding Qi directly shook his head in denial.

Although the little cutie is now very big, even bigger than the Canadian lynx that Ding Qi used to see on the Internet, with a body length of nearly 1.8 meters and a weight of about 60 kilograms, like a leopard.

Ktinch knew that the male lynx was in heat when it reached adulthood, between two and a half and three years old. Females will be earlier, between one year and eight months to two years old. And the cutie is obviously a male lynx, and it's still early for it to come into heat!

Elder Bucks continued Dingch's question:

Although Xiong Daxiong and Xiong Er said that they went out at night, they both went to eat the fish and some tubers that Mei gave them in the yard, and they couldn't get out of the yard. And our canteen is close to the bamboo forest outside the courtyard, so everyone thinks that it may have been stolen by animals. ”

Ding Qi gave Elder Buck a direct look:

"Have any of you ever seen an animal that eats from a hot pan? I've grown so big, why haven't I seen it? Animals that are not afraid of hot food, there really aren't! ”

Ding Qi said that he had never seen anything, based on the amount of knowledge he had gained from the twenty-first century, and this sentence was really only he dared to say in primitive times!

"Well, so be it, I'll settle this matter. How many days has it been since I lost something? ”

Ding Qi thought about it, and it is estimated that only he and the little cutie can solve this matter. Why?

The main reason is that primitive people are night blindness, and they can't see anything at night without light, which is worse than a blind person. Although Tinch has been working hard to improve the situation, it will not happen overnight.

Night blindness is mainly caused by a deficiency of vitamin A in the body and can be treated by supplementing with fruits such as apples, spinach, liver and fish.

Among the above-mentioned foods, apples are still growing in Xinjiang, and spinach is a product of Iran. Ding Qi can only work hard from animal liver and fish, and now fish has become a staple food for daily consumption, but the effect is not great, and it needs to be insisted on, I believe there will be an effect.

And animal offal made Ding Qi a little puzzled, primitive people didn't eat animal offal! The reason is that the internal organs are too dirty and difficult to deal with, at most they eat the heart, like the liver, lungs, stomach, intestines, etc., and they don't eat it at all, and they just throw it away! Ding Qi listened to it at the time, scolded his mother, and said that he deserved not to see it at night.

Animal liver is an important source of vitamin A for humans.

Therefore, since then, the internal organs of animals in the tribe have to be cleaned and eaten. As for how to deal with it, with the guidance of Ding Qi from the countryside and the army, it is not a problem!

"These days, I've been throwing food away every night, and I guess that guy will come over tonight."

Elder Buck talked about the situation and called each other "guy", which was also a species that he couldn't figure out the other party, so he could only use these two words to describe it.
