Siheyuan: Returning from studying abroad, with extraordinary understanding

In a small world.

Various medicinal herbs floated in front of Lin Changqing. As Lin Changqing's mind moved, the surface of the herbs began to be covered by spiritual springs.

The medicinal materials are slowly crushed and slowly combined with the spiritual spring water, turning into soybean-sized droplets.

These droplets are the essence of medicinal materials that have been baptized by the spiritual spring.

Depending on the different medicinal materials, Lin Changqing extracts different medicinal essences.

With the help of the small world, it was not difficult for him to extract the essence of all medicinal herbs.

If it were in the outside world, Lin Changqing would not be completely sure of extracting the essence of the medicinal herbs.

This is because, in the outside world, he had no way of keeping the extracted essence of medicinal materials in a vacuum environment.

It can indeed be done with the help of certain machines, but that would be too troublesome.

This can be easily done in the small world, so there is no need to add trouble to yourself.

The droplets arranged in front of Lin Changqing were fused together one by one in a certain order and proportion.

Lin Changqing has a strong mental power and the help of the small world. He can clearly control what medicinal essence to add and how much to add each time.

As the essence of medicinal herbs was added, the liquid droplet in front of Lin Changqing, which served as the basis, gradually grew larger. After adding the essence of hundreds of medicinal herbs, the liquid droplet became the size of an apple and became a water ball.

Although this water ball will undergo certain chemical changes when adding various medicinal essences due to their different properties, the chemical changes are not drastic.

They were all slight chemical changes, at most changing color, so this water ball did not achieve the result that Lin Changqing wanted.

Lin Changqing knew that this was because of the lack of powerful energy that could cause them to undergo a qualitative change.

For example, nuclear fission and nuclear fusion both require powerful energy to drive the reaction.

The same is true of ancient alchemy.

Otherwise, there wouldn't be the saying of refining the elixir for 749 days or 981 days.

Of course, this statement is not accurate, because in ancient times, the conditions for high temperatures were not met.

In other words, in ancient times, it was basically impossible to reach a temperature of several thousand degrees when refining elixirs.

However, in Lin Changqing's little world, it's possible at any time.

Lin Changqing no longer hesitated. With a thought, the surface of the water ball was covered with a layer of flames. The next moment, the water ball began to boil.

Wisps of white smoke drifted out from above the water ball.

The water ball was undergoing a violent chemical reaction. Lin Changqing's mental power covered the entire water ball, feeling all the details of the reaction.

The first time he refined the elixir, he didn't think he could succeed. He felt it carefully to verify whether the results of his simulation were correct and what details he had not thought of.

In the small world, his mental perception is very sensitive and he can sense any details of the chemical reaction of the water ball.

This chemical reaction did bring a lot of surprises to Lin Changqing.

Real chemical reactions are indeed not comparable to those simulated. During the simulation process, there are indeed many things that he overlooked.

The real situation is more complex and detailed than the simulation.

This time he gained a lot. Even if he couldn't successfully refine the elixir he wanted, it wouldn't be much of a loss for him.

As the chemical reaction in the water ball continued, Lin Changqing sensed that some molecules were destroyed due to the high temperature.

Through his detailed perception, Lin Changqing realized that alchemy is a very complicated process.

In chemical reactions, the temperature of the flame needs to be constantly adjusted. Different chemical reactions require different temperatures.

In this way, the reactions of different parts of the water ball require different conditions. Fortunately, Lin Changqing was refining the elixir in the small world, otherwise, just adjusting the temperature of different chemical reactions would make him exhausted.

In the outside world, even with Lin Changqing's mental power of more than 5,000, it was not going perfectly.

It’s different in the small world. No matter what the environment is, all he needs is a thought.

Although the alchemy may not be successful this time, the elixir that is refined will also be a very powerful one.

You know, this pill contains the essence of hundreds of precious herbs.

At the same time, Lin Changqing also noticed that the high temperature of the flame would evaporate some of the essence of the medicinal materials, causing waste.

Fortunately, in the small world, Lin Changqing was able to retrieve them.

However, at the beginning, Lin Changqing had no experience, and some of the essence of the medicinal materials was carbonized due to the high temperature.

That's right. Lin Changqing thought that the ancients needed such high temperatures to make elixirs, which would only destroy the essence of these herbs.

Because this time he was making the elixir, he used herbs, which naturally carbonized when exposed to high temperatures.

After carbonization, the medicinal effect will naturally disappear, so there will naturally be no good results from using herbs to make elixirs.

Most of the herbs used will be carbonized, so the pills made from them will be charcoal.

This is not much different from eating ordinary charcoal.

Therefore, it is inevitable that it will be ineffective and will also harm the human body.

It was inevitable that the ancients used minerals to make elixirs.

But why did Lin Changqing still use high temperature to refine the so-called elixir?

The reason why he did this was because of the existence of the spiritual spring.

Through his experiments, he found that after the medicinal materials and spiritual spring water are combined, a stable structure will be formed, and even at high temperatures, the medicinal materials will not carbonize quickly.

Moreover, Lin Changqing always pays attention to the chemical reactions of the water balls and senses the changes in the molecular structures.

Except for some carbonization at the beginning, after Lin Changqing made adjustments, no medicinal materials were carbonized.

It is precisely because of this that Lin Changqing noticed that there were some differences between reality and the simulation results.

The simulation results are all under the most ideal conditions, but in reality, there are always various factors that influence the results, which may be different or even unsatisfactory.

However, Lin Changqing is not incapable of making the actual results consistent with the simulation results.

In the small world environment, he can do it.

In other words, the small world is the most ideal simulation environment.

The mistake was not due to Lin Changqing's operation, but because he had never seen such a situation before.

With experience, the results are different.

Half an hour later, after Lin Changqing's careful adjustment, the moisture in the water ball slowly evaporated, leaving the essence of the medicine, and the water ball gradually condensed into a thumb-sized white pill.

However, this white pill can only be considered a defective pill.

Although it had the effect that Lin Changqing wanted, it was still too weak for him.

If the efficacy of the elixir he wanted was 1, then the efficacy of the elixir he was refining now was only 0.1, a ten-fold difference.

Although it is possible to refine ten pills and use them as one, they are too small for Lin Changqing's current physique.
