Qi Ke is not the only one who has found this difference, there are many smart people, not worse than Qi Ke, but others don't know how to use some statistical methods like her, but just by looking at it with the naked eye for so many days, you should be able to see something.

"Xiao Ke, have you noticed? The necks of the natives are not the same as ours. Qian Youqiao and several girls of the same age huddled on Qi Ke's ox cart to talk to her, Qi Ke's behavior these days made their small circle of people believe that she must have read a lot of books and know a lot of knowledge they don't understand.

"Hmm." Qi Ke withdrew his gaze from the passers-by, and instead glanced at the necks of the girls around him one by one, and then touched his neck, "You have lived on the border for a long time, have you ever wondered why your neck is so thick?" ”

The girls looked at each other, and their eyes fell on Qian Youqiao.

Qian Youqiao smiled bitterly and nodded slightly, "Have you ever thought about it, the water and soil in the north are not good, there are many people with big necks, everyone is used to it, we are from different backgrounds from ordinary military households, so we know some from childhood." ”

"It's good that you realize that this is a disease, think about the passers-by who passed by before, they are all dressed as poor people, but their necks are of normal thickness, which shows that there is food to improve the big neck disease in the local area."

"That's right!" The girls became excited and chattered quietly, "I see, the group of people who passed by earlier are all thin-necked!" ”

"The seaside is a good place, and after settling down, find a few locals to learn a few local dishes, eat more local vegetables and meat, and it will definitely get better after a long time." Qi Ke said calmly.

"I think so too, but I don't know the bottom of my heart, and now that you say the same, then I'm relieved."

Qian Youqiao patted his chest, looked at each other and smiled with his sisters, northerners who had never seen the sea came to settle down and live by the sea in the south, not to mention girls of their age, older people would have the same worries, afraid of all kinds of discomfort, but at this time they had less than half of their worries, just like taking a reassuring pill.

"I've been thinking all the way, after walking such a long way, I must have a good meal when I settle down, but looking at this environment, I feel that the flood has not receded at all, it is wet everywhere, and the local people are so hungry that their faces are yellow and thin." A little sister sitting next to Qian Youqiao said.

"Dong'an Mansion is the easternmost big city in Heyang Prefecture, it should belong to the estuary, after passing the state capital of Heyang Prefecture, you found that no, the water network is getting denser and denser, and we are no longer short of water, and it is also a large plain suitable for farming, what are you afraid of, it is not good to farm without lack of water, however, the disadvantage is that there is a big flood every year."

Qi Ke seems to be talking nonsense, but it still acts like the maximum imagination that ordinary people can do, in her own opinion, in fact, one sentence can summarize the current geographical situation - flood water carrying sediment accumulation - alluvial plain, flat and open, fertile land, as long as the flood continues, sending sediment every year, this great plain will continue to expand the area.

Once these geographical conditions are well managed, it will be a land of fish and rice with developed economy and prosperous commerce.

"Don't scare us!" The girls are trembling, they are going to settle here, who can stand the flood every year.

"I'm scaring you, when you settle down, hurry up to the street to buy, what to buy, here is a dense water network, the climate is humid and warm, the advantage is that the water and soil support people, men and women are born beautiful. But, dampness is a breeding ground for disease, remember what I said? ”

The girls nodded in unison, and then eagerly asked what moisture-proof things to prepare.
