"Bai Gong Dacai, this Artemisia annua water is really useful! There are already patients who are starting to go into remission. Zhang Zhongjing said excitedly.

Lao Zhang was the happiest to see that this Artemisia annua juice irrigation was really useful, because this not only meant that the losses of the military and civilians in Shouchun were reduced, but also that in the future, in addition to Shu Qisan, there would be another more efficient and easy-to-find prescription for malaria.

"Don't dare to be an old man...... It's just a good time for the meeting, just for the meeting, but pay attention to the hygiene of the recuperation area, clean up the stagnant water, and prevent mosquito breeding, and continue to keep an eye on it. Bai Tu seemed to be in little interest.

Malaria is mainly transmitted by mosquitoes, and the effect of isolation is not so great, and the main thing is to repel mosquitoes and maintain hygiene.

"Is Bai Gong worried about the curative effect of Artemisia annua water? Hey, it is already a blessing in misfortune to have the current effect, even if there is enough Shu lacquer, it will not be better than now. Zhang Zhongjing said with relief.

Sure enough, a handful of Artemisia annua two liters of water, minced to make juice and drank - such a crude extraction, the effect is limited.

Otherwise, it would not be the turn of malaria to continue to be arrogant for more than a thousand years......

Zhang Lao also knew that it was useless to cook Artemisia annua, and the times and technology limited the means of cold brew, and only manual "raw squeezing" was possible.

"I have a student who has a fast brain, maybe he will find a way." Bai Tu said.

He was still waiting for Pang Tong's reply, although he ...... Intellectually, Bai Tu has understood that Pang Tong should also be "desperate" about this.

After all, ether, gasoline or something, where can it be made now?

Otherwise, Yuan Shu would have been blown up by him a long time ago, what kind of malaria is not malaria......

It's just that he still has some perceptual fantasies, so Bai Tu is still looking forward to Pang Tong's reply.

Zhang Zhongjing did not persuade again, but looked at Bai Tu with satisfaction - if he is a doctor and a disciple of Zhang Lao, he must reverse Bai Tu's mentality, after all, a doctor is not omnipotent, and it is his duty to be dedicated to every patient, but if there is such a big reaction to every patient who cannot be treated, then he is not far from washing his hands in the golden basin.

Modern medicine can't save all patients, let alone in the late Eastern Han Dynasty? Do your best, just obey the destiny of heaven......

However, Bai Tu is a prince, so Zhang Zhongjing hopes that Bai Tu can be maintained, just like King Qi Xuan saw that his subordinates were going to slaughter cattle and sacrifice, and looked at the cow trembling, and felt distressed...... Let your subordinates change to a sheep to slaughter.

It looks hypocritical to people in modern times, and people at that time looked picky, after all, sheep were much cheaper than cattle at that time......

However, when Mencius heard about this, he gave a positive affirmation, believing that this was a manifestation of the "benevolence" of King Xuan of Qi.

Just like a gentleman who can eat meat, but is unwilling to kill chickens and sheep with his own hands, it seems to be hypocritical in principle, but it is precisely the existence of "benevolence" in his heart that can produce this "unwillingness", even if it seems stupid sometimes, it is better than nothing.

What's more, Shouchun is almost half of the city's people, and after really doing a math problem, he found that the proportion of injured people was lower than expected, so he smiled...... That's what is scary.

As a doctor, Zhang Zhongjing should be happy, but it is not Bai Tu's turn to be happy.

At this moment, Bai Tu's official seal shook, it was Pang Tonglai's reply, Bai Tu hurriedly confessed to Zhang Lao and began to check.

Seeing the schematic diagram that Pang Tong drew for himself, Bai Tu was stunned for a while - how does it look like a supercritical fluid extraction equipment?

Supercritical fluid extraction can be said to be the most efficient and purified cold brew method, but in the late Eastern Han Dynasty, it was more unreliable than ether and gasoline......

In principle, it is to select those special gases or liquids, which will behave as supercritical fluids in a special pressure environment, that is, there are some properties of gases and some properties of liquids, in this state, the substances to be extracted are dissolved, and then returned to normal, and the supercritical fluid becomes back to ordinary gases or liquids, leaving only extracts.

With low dissolved residue and high efficiency, it can be said that the fighter in modern cold brew technology is just ...... Death is expensive, death is expensive.

Generally, carbon dioxide can be selected for this fluid substance, but it is necessary to add hundreds of times the atmospheric pressure to make it show the state of supercritical fluid, and the whole equipment is expensive.

Although Bai Tu didn't understand it very well, he had only been exposed to it when he was writing papers before, but when he sent information to Pang Tong not long ago, he read it all, so he recognized this equipment at a glance, which is very similar to supercritical fluid extraction equipment!

This was not only expensive in the late Eastern Han Dynasty...... Where to add a few hundred atmospheres to the white chart?

However, continuing to look down, Bai Tu was stunned by Pang Tong's imagination......

The world of Chenghime is very different from the world before the white map crosses, but ...... For a long time, in civilian technology, Bai Tu has not found any difference, so this point has been ignored.

However, as a native, with a high IQ and an open-minded "local", Pang Tong found a new method from the super-outline textbook given to him by Bai Tu.

Although the textbook is beyond the curriculum, the basic principle Pang Tong has already understood, so he has found a substitute for supercritical fluids - internal breath.

A very mysterious thing, Lu Bu also told Bai Tu before, a very small number of exercises that lay the foundation for martial artists contain some laws of breathing, and a large part of the exercises attached to the battle armor will also have a corresponding part.

Although the warriors of the castle world mainly practice "kinetic skills", that is, exercise, rather than meditation, but through breathing, there is also a magical power that can be recharged with combat armor in normal times.

Generally, the consumption of gilded armor requires the user to have a certain amount of internal breath to be able to drive, and the white picture ...... It's stuck in this step.

If there is no part of the Tuna in the manual of the wood and stone battle armor, then it means that the user's qualifications are not good, and he must find someone else to consult and improve the exercises before it is possible to continue to improve.

It is said that the inner breath or something should be a conceptual product of the "idealistic" level, which cannot be seen or touched, and is neither a gas nor a liquid.

It's not that after the internal breath is turned into liquid, there is a new set of "blood vessels" in the body to flow the internal breath, but when it is used, it can not only charge the battle armor, but also affect reality, which conflicts with the principle that many white pictures are handed over to Pang Tong.

Therefore, Pang Tong already has some research and ideas in this regard, and he also has the best "experiment" - Zhou Tai.

Although Zhou Tai is still a step away from Jinyu, he is now the closest to the Jinyu battle armor under Bai Tu's command, and his body is different from ordinary people, and even his pure combat power is not inferior to Gao Shun wearing the Jinyu battle armor.

Zhou Tai's internal breath is already "liquid", of course...... Just an abstract liquid, a person drives the armor to the point where the inner breath is exhausted, and when he is normal, the weight will not change.

Pang Tong was very curious about this state, and had done some research and experiments before, and finally found that this abstract liquid could also be released when the warrior was concentrating, just like the "non-existent" internal breath, which could knock down trees and even blow up a pit in the ground when it was released.

In the end, Pang Tong came to the conclusion that the substance of internal breath, when it is in the body of the warrior, is between existence and non-existence, and when the warrior releases it, it has certain physical properties......

In the current situation of insufficient data, Pang Tong established a hypothesis, that is, the "inner breath" exists as the will of a warrior, and when this will is recognized by the external objects of heaven and earth, it will exhibit the same properties as the real matter in the outside world.

When the outside world does not recognize the will of the warrior, the "internal breath" does not exist - but this violates the conservation of matter, so Pang Tong changed his thinking, not "non-existence", but the superposition between "existence and non-existence".

By extension, Pang Tong made a hypothetical experiment.

If a wild goldfish caught by Gan Ning is put in a bucket of seawater, the barrel is covered with wooden planks, and a few catties of salt are put on the wooden board, at this time, a warlord who appears with internal breath hits the plank in the air, the plank is broken, and the big goldfish dies because the concentration of the sea water is too high, and it is replaced by a warlord who has no internal breath, and the plank cannot be broken through the air, and the big goldfish survives......

In other words, if you change to a warrior who does not know whether his will is recognized or not, the big goldfish is in a superposition of death and immortality, which is the famous hypothesis of "Pang Tong's wild big goldfish".

Bai Tu has no interest in Pang Tong's big goldfish, but ...... Pang Tong also explained one point in the letter, that is, "internal breath" can be used as a "supercritical fluid".

There is no need for hundreds of air pressures to constitute supercritical conditions, as long as the martial artist can control his internal liquefaction and external release, he can be used as a substitute for supercritical fluids, or...... Should this be considered an "internal fluid"?

It doesn't matter how you name it, the important thing is that Pang Tong has not only simulated it with a special trick, but has also been actually experimented in Wu County, and when Zhou Tai is the provider of internal fluid, he can use it to extract the juice in Artemisia annua with high efficiency!

Even Pang Tong felt that if he studied further, he might be able to control the nature of the internal breath through the martial artist himself, and separate the effective substances in it in a targeted manner, but ...... Time was short, and there was no time to study so deeply.

After Bai Tu understood it, he immediately began to organize the creation of extraction equipment in Shouchun, and then asked Tai Shici to try it......

The liquefaction of internal breath is the basis for extraction as a "internal fluid of internal breath", and in addition to Zhou Tai, there should be only a few Jinyu generals who can do this.

At the same time, Bai Tu also immediately sent someone to inform Lu Bu and Sun Ce, who were still in Runan.

Pang Tong has been successful in Wu County, which shows that this method is feasible, but ...... It is not so easy to manifest the liquefied internal breath only in the liquid state and recover it after extraction.

A day later, the equipment has been built by Bai Tu's concentrated manpower, which looks like a supercritical fluid extraction equipment, but in fact it is very "pocket-sized", Tai Shi Ci can support both ends of it with his left and right hands, one side is the import, and the other side is the exit - if the internal interest is not recycled, it will not be long before Tai Shi Ci will be exhausted.

Two days later...... Tai Shi Ci successfully extracted two liters of essence, but seven or eight pieces of equipment had been destroyed, but fortunately, Bai Tu had been organizing people to make it!

This thing is more dangerous than ether, although it is non-flammable, it is aggressive at every turn, and it blows the device away......

Tai Shici was also a little surprised, usually he still preferred a skill-based general, but his performance was not satisfactory.

As for the reason why Zhou Tai was successful, Bai Tu estimated that it was because Zhou Tai's physique was special, his strength had not reached the level of the Jinyu general, and he was weaker after the liquefaction of the internal breath, so judging from the success rate given by Pang Tong, it surpassed Tai Shici.

At this moment, Lu Bu and Sun Ce had also returned overnight.

This extract is indeed useful, but Tai Shici is alone, and the efficiency will definitely not be able to keep up, and now Bai Tu can only look forward to his father-in-law and second brother......
