Lu Fan smiled.
He is now certain that there is definitely an invisible hand behind this matter.
Otherwise, how could Wu Lihui, an ordinary worker and perhaps an ordinary farmer before, know the title of heavy metal toxicology expert? How could it be possible to hire someone like Professor Ma?
The workers may not see the trick, and they may be happy that the experts are here.
But Lu Fan knew that this matter was not that simple at all.
Of course, he didn't care about some bullshit heavy metal toxicology expert. It wasn't easy to cause trouble in front of him.
It would be fine if this expert could speak and act according to his conscience.
If he wants to play any tricks, Lu Fan is not a vegetarian.
"I heard that you want to find the source of his cadmium poisoning here? I think it is a waste of effort. How can ordinary people have sources of cadmium poisoning?" Professor Ma looked a little impatient.
Obviously, he felt that it was a waste of time to go to the patient's home to find problems.
Who has a source of cadmium poisoning at home?
According to his wishes, just go directly to where Wu Lihui works.
Of course, this was also the intention of the person who invited him.
"How can you know if you don't look for it?" Lu Fan did not argue with him.
Facts speak louder than words. Once he finds the source of the poisoning, let's see what this so-called expert says.
"Let me look around, is there any problem?" he asked Wu Lihui.
Wu Lihui looked back at Professor Ma: "No problem, you can read whatever you want."
Since Professor Ma said there could be no source of poisoning in his home, he was relieved.
A big expert from the province must know more than a bumpkin in the village, right?
Seeing Lu Fan wandering around the room, Professor Ma's expression became even more disdainful.
"Do you know the common ways of cadmium poisoning?"
He suddenly asked the other people loudly.
Without waiting for the people to answer, he asked himself and answered: "There are three main ways. The first is to work in places where cadmium and its compounds are smelted and used for a long time."
"The second type is living or working on cadmium-contaminated soil for a long time."
"The third type is engaged in research on cadmium metal for a long time."
Professor Ma made a popular science expression.
"So, it is impossible for my family to have a source of cadmium poisoning, right?" Wu Lihui felt that he understood what Professor Ma meant.
"That's right!" Professor Ma gave him a positive reply.
Zhao Qian looked at Lu Fan, who was still looking around, and suddenly felt helpless.
Even experts have said this, and there is basically no other possibility for this matter.
So Lu Fan's current busy schedule seems like a joke and a tragedy.
Zhao Qian wanted to run over, grab Lu Fan, and tell him to stop working.
At this time, it is better to consider how to compensate.
But Lu Fan obviously didn't think so: "Professor Ma, you missed one more situation."
He straightened up.
"Young man, do you know who you are talking to?" Professor Ma snorted coldly.
"I am forty-three years old and have studied heavy metal toxicology for more than twenty years. Do you think there will be situations that I haven't thought of?"
"Then I can only say that all your research in the past twenty years has been on dogs. There is indeed a situation that you did not mention." Lu Fan said with a smile.
Professor Ma's expression changed drastically.
Zhao Qian and Wu Lihui’s expressions changed drastically.
The two worker representatives who came with me also changed their colors.
None of them expected that Lu Fan would attack Professor Ma, a great expert from the province, so directly!
This is too rude!
Professor Ma was so angry that his whole body trembled.
"what are you saying?"
He took out a bunch of things from the bag he was carrying and threw them on the table.
"Please take a closer look. These are my identity certificates and achievements. My academics cannot tolerate your insult!"
Zhao Qian looked towards the pile of things.
There are several certificates of various kinds in there, as well as work certificates, expert certificates and the like.
It seems that Professor Ma is indeed not an ignorant person. Ordinary people can't get so many things.
Even people like Zhao Qian who have seen the world think Professor Ma is a bit powerful, not to mention Wu Lihui and the two workers' representatives.
These people have always admired great experts and scholars the most. When they saw the proofs that Professor Ma presented, they all wanted to pay homage to Professor Ma.
Only Lu Fan just glanced at those things: "So Professor Ma's academic level must be proved by these waste papers!
So many certificates and documents, in his eyes, are like waste paper!
But even Professor Ma had to admit that Lu Fan was indeed on to the point.
A truly capable and knowledgeable person does not need to carry around his various certificates to show off.
Only people who are not confident enough will readily use these things to bluff people.
"Stop talking nonsense!" Wu Lihui shouted loudly without reacting.
"We all have great trust in Professor Ma's skills, and we believe what he said is correct. But you, since you said there is another case of poisoning, why didn't you just say it?"
"You're right." Lu Fan actually nodded, "Another situation is that using cadmium-plated containers to store food can also lead to cadmium poisoning in humans."
Wu Lihui originally wanted to say something more, but he suddenly remembered something and couldn't continue.
But Professor Ma himself reacted: "Impossible! Modern people have common sense, how can it be possible to use cadmium-plated containers to store food?"
"It's hard to say. Whether it's there or not, we can just go into the kitchen and have a look." Lu Fan smiled, turned around and walked into the kitchen.
"I want to see what tricks you can pull off!" Professor Ma snorted coldly and followed in.
He didn't believe that in this age of advanced information, there would still be people using cadmium-plated containers to store food.
He must follow him and expose Lu Fan on the spot.
Zhao Qian and the two worker representatives also followed in. Only Wu Lihui, who had been thinking about something, walked very slowly. As the owner, he was the last one to enter the kitchen.
As soon as he entered the kitchen, his heart skipped a beat.
He saw Lu Fan standing next to his gas stove, holding a bowl in his hand.
There was half a bowl of dark liquid in that bowl, whether it was soy sauce or vinegar.
"This must be vinegar, right? It smells sour." Zhao Qian sniffed. "Yes, this is jealousy." Lu Fan handed the vinegar bowl to Professor Ma, "How about Professor Ma, now, is there anything else you want to say?"
