The difference between activated carbon and ordinary charcoal is that it only needs to be steamed in a steamer. When he understood this truth, Li Mengxi was extremely emotional. He thought activated carbon was so difficult, but it was so simple.

Looking back on the entire charcoal-making process, Li Mengxi thought to himself that if he had to think of a way by himself, he would never think of using steam to process charcoal.

Li Mengxi carefully thought about everything. When he thought of activated carbon and the word "activated", what he thought at that time was that it must be a living thing, bacteria. He thought of using microorganisms to process charcoal, and wanted to use biological organisms to process charcoal.

Method to work backwards to deduce the principle of activated carbon.

However, if this is the direction, it will never be possible to reproduce activated carbon. Therefore, as long as it involves microorganisms, the difficulty of selecting microorganisms, the cultivation of microbial living conditions, pH nutrients, and other conditions that need to be maintained, as well as the conditions that need to be maintained in Han

Microorganisms cannot be visually observed at all under low-tech technology, which means that if you choose the direction of microorganisms, you may not be able to complete all microbial tests in your lifetime.

The truth is hidden in endless uncertainty. However, Li Mengxi was lucky to have a young brother. Fortunately, most children like to ask questions. They will ask why the sun rises and why the leaves fall. When apples fall from the tree,

If it falls from the sky, they will also ask why the apple fell to the ground instead of flying into the sky. There must be many children who will ask this question.

Children who have a simple and infinite curiosity about the world are naturally suitable for exploring the infinite mysteries of nature.

My younger brother is just one of countless ordinary children. Fortunately, Li Mengxi never ignored the weird questions his younger brother liked to ask and encouraged him to think more.

Why does the sun rise in the east and set in the west, why does the wind blow, why does the rain fall, why are the flowers bright, and why do birds fly? Li Mengxi clearly knows how much children can have endless questions and curiosity about these ordinary things.

A huge achievement.

Fortunately, Li Mengxi discovered his younger brother's unique way of thinking about problems. Even more fortunately, he did not ignore what his younger brother said just because he was a child or because he was childish and ridiculous. Only then could he discover that children have miraculous scientific intuition.

Li Mengxi only guided his younger brother to use his imagination when teaching him, instead of forcing his younger brother to learn as many words as possible every day, and beating him if he couldn't finish learning; he just showed more respect and respect to his younger brother.

Although every sentence my brother said was childish and ridiculous, it was all based on thinking and observation. As a result, the rewards were so rich.

When Li Mengxi encountered an incomprehensible problem in papermaking, his younger brother came and asked curiously what he was busy with.

At this time, Li Mengxi did not ignore his younger brother because he was a child, nor did he ignore his younger brother because he was upset about the complexity of papermaking. Instead, he casually told his younger brother about the problems he encountered, "When making paper,

I have to sink the hemp into the pond. I wonder why it is like this? My brother can’t figure it out.”

As a result, the younger brother thought about it innocently in Li Mengxi's arms and said, "Put it in the water to wash it."

Of course it won't be washed. If it's just for washing hemp, it won't be thrown into the pond for a year or two.

Li Mengxi smiled and gently rejected his brother's answer.

The younger brother's curiosity did not stop because of this. The younger brother added that it was for feeding the fish.

Another more hilarious answer.

At that time, Li Mengxi's idea was that growing hemp and sinking it into the pond was not a way to feed the fish - because there are not many nutrients in hemp and bark, so hemp and bark are not food for fish - fish do not eat bark - they eat bark.

The ones should be bacteria and microorganisms - such as mushrooms, which grow on the bark of trees.

Look, his brother said that raw sesame is used to feed the fish. What a ridiculous answer. Li Mengxi did not laugh it off. Instead, he thought about what his brother said seriously, reasoned about it carefully, and then prepared to deny his answer.

It was precisely because Li Mengxi thought about it for a while.

My brother said that the raw sesame pond is for feeding fish, which is certainly not true. However, this answer has already touched the edge of the truth.

On a marginal basis, Li Mengxi naturally associates fish with other creatures. When he infers microorganisms, inspiration comes naturally.

Relying on limited scientific knowledge, Li Mengxi figured out the principle of making hemp in the pond, which is microorganisms.

This was the first time that Li Mengxi got important inspiration from his brother's casual words.

From here on, Li Mengxi realized the precious imagination and curiosity of children.

Since this time, Li Mengxi has deliberately used his younger brother to solve the problem.

If you have any questions that you can't figure out, you might be able to answer them by asking your brother.

In papermaking, after the raw sesame is sunk in the pond, when it is time to make paper, the pulp must be boiled for two days or even longer.

It was winter, and firewood was in short supply. If it hadn't been for winter, Li Mengxi wouldn't have been obsessed with the issue of firewood and dye. It would take two days to boil the pulp, so how much firewood would he need?

Li Mengxi was wondering whether he could save some firewood, and why the pulp had to be cooked for two days?

Li Mengxi asked his brother this puzzled question. He asked, why did it take two days to cook?

My younger brother casually said, "Is it not cooked properly?"

This... is not rice, why is it not cooked properly? My brother must have thought that cooking is the way to cook something.

This childish and innocent answer was just another answer.

The reason why the pulp needs to be cooked for two days is because it is not cooked properly.

The reason why it was not cooked well was because the meat could not be cooked well in the high mountains, which involves air pressure, boiling point, and a lot of other things. Then, Li Mengxi thought of the pressure cooker.

Thus, another important improvement in papermaking was born.

After advancing to the pressure cooker, Li Mengxi's exploration has stopped here. He is satisfied. However, his younger brother's curiosity and doubts are much more than Li Mengxi's.

The younger brother asked why he had to boil the hemp to make paper, and why he couldn't make paper if he didn't boil it.

Yes, why?

Li Mengxi began to think about the core principle of papermaking.

He figured out that there must be a substance in the bark. After this substance is eaten by microorganisms, the cellulose can be boiled out and paper can be made. This must be the case.

At this point, Li Mengxi has understood the core key to papermaking.

If he didn't have his younger brother, it would be the end of the world, and he wouldn't think about taking another step forward.

But the younger brother said naively that he didn't want the microorganisms to eat, so he drove him away and refused to let him eat.

Oh my God, what an innocent and cute answer. My brother thought that microorganisms were birds, and could they be driven away?

But if you think about it seriously, hey? Yes! In addition to using microorganisms to remove components from the bark, is there any other way to complete this process? The biological treatment method takes too long after all, and the papermaking process takes up to two years.

Years later, it would be very unfavorable for mass production.

The idea is extended here, combined with the knowledge already known, and then associated with the industrial papermaking technology of later generations. The papermaking industry is a very low-end industry. Since it is an extremely low-threshold industry, it does not use too high-end chemicals. Since

If high-grade chemicals are not used, it means that only low-grade chemicals are used.

What can low-level chemicals be? Acid and alkali salts, grease, alcohol, etc.

So without much testing, Li Mengxi luckily found out that the key ingredient for pulp processing is alkali.

After that, the pulp could be made in an alkaline environment of high pressure and high temperature. Li Mengxi asked his brother, what should I do if the pulp is black?

The younger brother said to wash it and spread some noodles.

The washing and bleaching method was born, and so was the dyeing method.

The charcoal color removal method was finally a good method that Li Mengxi came up with. Charcoal can decolorize. This was Li Mengxi's common sense and he knew it without thinking about it. However, Li Mengxi didn't know how charcoal became activated carbon.

Li Mengxi once again brought his younger brother into the investigation process.

After the wood model close to the microstructure of charcoal was made, after the twine balls were poured into the wood model, and when Xiao Bian wanted to use a stick to pull out the twine but could not, Xiao Bian thought about it while playing, and thought that he could blow it out.

At this time, Li Mengxi thought he had found a way to reuse charcoal, but unexpectedly, he accidentally discovered the creation of activated carbon.

There are so many creations - the principle of hemp sinking, high temperature and high pressure pulp cooking method, non-biological material treatment method of alkali pulp cooking, pulp water washing and decolorization method, pulp dyeing and paper making method, and finally activated carbon, in just a short time

Over time, many extraordinary creations came from my younger brother's innocent, curious and childish questions and innocent answers.

How can one be called a scientist if he has so many creations? Even if he creates indirectly, he is still a scientist.

But, you know, Xiao Bian is only three or five years old and doesn't even know how to read.

The method of training scientists is so simple, so fast, and can produce results.

Li Mengxi just did not force his younger brother to read and learn Chinese characters every day, and did not let boring study take up more important time for observation and imagination; Li Mengxi just had enough time to accompany his younger brother, he respected every question he asked, and treated his younger brother well.

Every childish question is given positive feedback, rather than being indifferent or impatiently scolding, which destroys the precious enthusiasm of children to explore the unknown; Li Mengxi is just someone who can explain a problem but cannot explain it in the simplest way.

When he explained it in a clear way, he was willing to spend some energy and time to design some small experiments to guide his younger brother to find answers in his own exploration. And this exploration process involves playing with water, filling water with a bamboo tube, and holding a bamboo tube to fill water.

A broken piece of wood, using a stick to poke out the twine balls from the broken piece of wood, this is just playing, it is just a simple game.

This is all what Li Mengxi did.

If Li Mengxi cracked all the core technical principles of papermaking and successfully created activated carbon, even if he only reversely restored it based on the knowledge of later generations, if he could reversely deduce the principles through reverse restoration, then he is enough to be called
