Regarding the toxicity of mercury, Li Yuanjia did not go into too much detail.

He can mention things without evidence, but he will definitely not "swear", let alone guarantee anything. The only thing he could do was to remind Han Cheng several times and ask them to take precautions when experimenting with mercury.

There is too much to say, and there is no good reason.

After all, even in Datang, Li Yuanjia can't escape the unique place where medicine is compared with other sciences, that is, it takes a long time and a sufficient sample size to prove it.

Among the various disciplines, medical certification is probably the most difficult.

Because of the prevalence of individual differences, it is difficult to explain any single case, even dozens or hundreds of cases, and there must be enough to prove it. For example, if a woman gives birth too early, it will affect her health and longevity, and the 1,000 cases counted by Li Yuanjia alone may not be able to convince the high-level people of Datang, let alone the common people. After all, a fixed mindset formed for hundreds of thousands of years, where is it so easy to change?

In the history of mankind, there are countless such things.

Not to mention anything else, just a yapian, which Europe and North America have been used as a miracle medicine to cure diseases in the nineteenth century, and has the same "noble" status in the medical world as brandy and leeches; Even in the first half of the twentieth century, many doctors swore that smoking was good for your health, until a large-scale survey involving hundreds of thousands of people began in Europe to finally determine that smoking is harmful to the human body......

Far from it.

As a mature doctor, Li Yuanjia certainly understood this truth, so he would warn Han Cheng and them, and ordered them to take precautions when using mercury, but the reason could only be prevaricated by "what appears in the book", and it was impossible to directly give a very definite conclusion.

"In this life, it's a stable!"

After secretly sighing in his heart that it was not easy for him to survive, Li Yuanjia waved his hand and said, "Okay, everyone else is scattered...... Han Cheng, you come with me, let's talk about this mercury matter. ”

"Yes, King!"

The others bowed in unison, looking at Han Cheng with a hint of envy in their eyes.

This tone obviously values this kid very much...... No, it should be said that I value the glass workshop and this mirror very much! However, the others didn't think much about it, after all, everyone now knows the vast "money" of glass, and they also know that although the reputation of the glass in the Han Wangfu is not obvious, it is because of the lack of production......

……

Just when Li Yuanjia and Han Cheng were discussing the possibility of making mirrors with mercury in the house, the ...... in Han Wang's Mansion No, it should be said that it is the overturning workshop of the imperial court now, and Zhang Cambodia is also continuing to discuss the problem of the assembly line with Wang Pu with high interest.

"Mr. Wang, I still don't understand!"

After visiting the entire assembly line, Zhang Cambodia frowned and asked suspiciously: "There are still so many people, and the tools are still those tools, why do you use this...... Pipeline huh? In this way, you can make several times more rollovers? This...... That's weird, isn't it? ”

"Haha, is that weird?"

Maybe it's because I've seen too many questions like Zhang Cambodia, Wang Puha smiled, and said with a relaxed smile: "To be honest, when I first heard the king talk about the assembly line, I also felt ...... Ahem, I think it's weird! But then I built it in its entirety according to the king's orders, and watched the carpenters make the tenth overturner, and I understood it completely! ”

"Oh? Why? ”

Frowning, Zhang Cambodia hurriedly asked.

"Well...... this"

After thinking for a while, Wang Pu took a deep breath and said: "In my opinion, there are two main points, one is that everyone focuses on making a part, so that they will become more and more proficient and faster...... The second is that one person has a limited amount of energy, and each of us is, and doing only one thing can make everything easier, not only to make those parts, but also to assemble them...... Xiao Langjun, do you understand? ”

When this sentence was finally asked, Wang Pu couldn't help but scratch his head.

In fact, although he now knows the assembly line of the dumping workshop, if he really talks about the principle, Wang Pu always feels that he still hasn't eaten these words thoroughly.

To put it bluntly, it is to know it but not to know why.

So after saying this, Wang Pu couldn't help but sigh: "Alas, if only the king was here, he would definitely be able to explain this matter......"

If Li Yuanjia heard what Wang Pu was thinking at this time, he would inevitably pout and reply to him: "Don't worry, your king and your level ...... Well, it should be a little higher than you, but that's it! ”

Li Yuanjia, who has never been on the assembly line, understands this thing purely on paper.

The key is that because the overturning thing is too simple, the assembly line is naturally simple, even if Li Yuanjia has only heard of the concept, but has never been in any assembly line, he can create it.

But in fact, any worker from the twenty-first century should do a much better job than him.

Li Yuanjia is like this, not to mention Zhang Cambodia, who is just looking at the flowers and flowers - don't think about the assembly line too simply, otherwise Ford has already built an assembly line for cars at the beginning of the 20th century, why are so many countries producing some small things still a small workshop-style production method, and it has lasted for decades?

This thing is really not as easy as imagined.

At least for Zhang Cambodia, who has been in Zhenguan for thirteen years, just listening to Wang Pu and then taking a look at the overturning workshop, it is impossible to completely figure it out.

So after frowning and thinking for a while, he asked seriously, "Mr. Wang, can you allow me to ask for advice here for a few days?" ”

"Huh? Doesn't Xiao Langjun need to study? ”

After a pause, Wang Pu asked in surprise.

In his opinion, the reason why this Zhang Xiaolangjun came to the dumping workshop should be just curiosity, like many officials who came before, can't he just take a look? How can you listen to the meaning of this, and wait a few more days to think clearly? What about the studies that are too learned? Didn't you pick up the sesame seeds and lose the watermelon?

"Hehe, I just got a clothes leave!"

After taking a deep breath, Zhang Cambodia hurriedly explained: "There is one month, which is enough for me to figure out this assembly line." ”

"This ......"

Frowning, Wang Pu hesitated.

This dumping workshop was built by Han Wangfu, and to put it bluntly, it is the credit of him and Chen Mu, so after the previous official was transferred, there was naturally no problem with bringing someone over to take a look, and everyone would give this face.

But if Zhang Cambodia wants to stay a few more days, it is not suitable.

Seeing the embarrassment on his face, Zhang Cambodia raised his eyebrows and asked, "Mr. Wang, is it inconvenient?" ”

"Well, it's a little bit."

After hesitating for a moment, Wang Pu nodded and said with a wry smile: "Now that this place is under the control of the imperial court, my words are not particularly effective." But Xiao Langjun, if you just want to understand the truth of the assembly line, there are actually a few workshops that can also be ......"
