The Baqili teacher said with a somewhat embarrassed face, "Mr.
Fan, I followed the patriarch's instructions and began to conduct a survey and statistics on the poisoned families, but I found that they were not evenly distributed, and the farmland at home did not match each other.
Not to mention, the food they eat is different, and the time for children to be poisoned also varies.
There is really no rule of thumb.
What's the clue?
And since the villages are spread out so widely, it's impossible for them all to get together.
If you said that the children are chronically poisoned, then it should be the constant absorption of toxins that causes the problem.
This disease shouldn’t happen quickly, so it’s harder to find commonalities.”
Fan Wei frowned after listening to the words of Teacher Baqili and said, "It would be a bit strange to put it like this.
It is obviously chronic poisoning, but there is nothing in common, that is to say, there is no fixed root cause of toxin absorption. , This is obviously impossible.
This kind of chronic poisoning must occur after a long period of excessive intake of elements, so the poisoned children must have something in common, but this commonality is very secret. " The old patriarch glanced at Baqili and said thoughtfully, "Baqili, couldn't you find anything in common between the poisoned children?
Even if they didn't eat together, maybe they ate the same dish from the same field.
Rice” "Old patriarch, this is simply impossible.
Think about it, this gathering area is so big.
Even if there are frequent exchanges between several villages, it is impossible for them to give away all their own rice and vegetables.
Doesn't he want to Living in the gathering area, rice and vegetables are all It is the greatest guarantee for a family’s life.
Who would give all the food grown in their own fields to others for no reason?
Others will not buy it.
Wouldn’t they have none in their own fields?
So, I think eating the same vegetables It’s not possible with rice.”
After hearing Baqili's words, the old patriarch stopped talking.
Because he is the patriarch, he naturally knows the situation in the clan best.
It is obvious that Baqili's analysis has been recognized and affirmed by him.
The problem, it seems, is not the food.
Fan Wei was a little confused now.
He obviously didn't live in the same village and didn't eat the same food, but why were the children in these villages poisoned?
How did the poison spread?
What is the root cause?
What is the reason why the children in several villages were poisoned by absorbing excessive phosphorus?
These are all questions that remain in his mind and need to be solved urgently.
The investigation has hit a bottleneck, and naturally there is no follow-up.
It seems that it is not simple and easy to find the root of the culprit.
Fan Wei thought for a long time before slowly saying, "Old Patriarch, Teacher Baqili, tell me, besides food, is there anything else that all villagers must use in their daily lives and that is very inconspicuous?
There is no problem with the food, it seems we need to look for other clues.”
"Daily life," the old patriarch thought for a while and said with a helpless smile, "We Ainu tribesmen are all trapped in this gathering area.
There is no rich life.
We are all farmers who work at sunrise and rest at sunset. , daily life is to work in the fields, go home to eat and sleep, to put it simply, eat, drink, poop and sleep.
It is impossible for the toxin to be absorbed into the body through the air."
"That's impossible.
The gathering area is so vast.
If it were spread through the air, how much phosphorus would be needed to poison people?
Not to mention that phosphorus is colored and cannot be seen by the naked eye.
Airborne transmission is unrealistic."
Fan Wei shook his head and said Denying the absurd suspicion of the old patriarch, he pondered, "Of the five things that must be done in daily life, eating, drinking, urinating, and sleeping, eating has been eliminated, and urinating and urinating are both excretion and cannot be absorbed.
As for sleeping, that's even more important.

It’s impossible.
By the way, there’s still something to drink.”
"Drink."
When Baqili heard this, he smiled helplessly and said, "You suspect that those toxins come from the water?"
"It's very possible," Fan Wei said, the more he thought about it, the more doubtful he became.
"Think about it, water is liquid, phosphorus is soluble in water, and water has great fluidity, not to mention water is the source of life and everyone must drink it every day.
Yes, doesn’t this have something in common?
Where does the water you generally use and drink in your gathering area come from?
Is it tap water, river water or stream water?”
After the old patriarch and Ba Qili looked at each other, he said to Fan Wei with a strange expression, "Mr.
Fan, you have never lived in this gathering area and don't know the specific situation.
Hokkaido is a large island located in the north.
Although the weather is good, there are not many streams and rivers.
There are relatively few rivers and streams in this gathering area, so sometimes they will even dry up in dry years.
So, we thought.
As a solution, a number of large reservoirs were built on the mountain.
The drinking water sources in the village come from there.
Such reservoirs are built on the mountains near every village.
The possibility of drinking water poisoning is not very high. , After all, it is possible that the phosphorus content in one reservoir exceeds the standard, but it is somewhat unlikely that the phosphorus content in so many reservoirs exceeds the standard at the same time.
Our sick children are scattered throughout the gathering area."
"Reservoir" Fan Wei was stunned and couldn't help but said with some surprise, "So, you don't drink water from streams and rivers, but directly use the water stored in the mountains.
Where does this water come from?
It's from the mountains.
Spring water?
Do these springs come from the same source?
If the spring water on the mountain comes from the same source, then no matter how many reservoirs you build, the water quality will be the same. " "The water in this reservoir is a bit complicated.
Some are mountain springs, some are streams and rivers, and some are rainwater.
I really can't tell the difference."
Baqili said at this time, "But what I can confirm is that each of us The villages are relatively far apart, or at least the mountains they are adjacent to are different, so no matter what water flows into the reservoir from the mountains, it cannot come from the same water source.
In other words, the water quality in each reservoir is the same.
Different.”
"If that's the case, then it may not be a water problem."
Fan Wei smiled helplessly, "It's really weird.
What is the source of phosphorus exceeding the standard?
If we can't find it in daily life.
If there is a problem, then I really don’t know how to start.”
The old patriarch's face didn't look very good either.
After all, if the root cause of the poisoning could not be found, it would mean that as long as the overdose of phosphorus still occurs among the children of the clan, they would get this strange disease again and never recover. .
Even if Fan Wei cures the sick children, it won't be long before the children are poisoned again and fall into life crisis again.
This is like a vicious cycle.
If the key point is not found, there will be no good changes at all
