Volume 2: The King's Way Chapter 186 Pang Tong's Wild Giant Goldfish
"Mr. Bai, this Artemisia annua water is really useful! Some patients have already started to feel better." Zhang Zhongjing said excitedly.
Old Zhang was very happy to see that squeezing the juice of Artemisia annua and drinking water was really effective , because it not only meant that the losses of the military and civilians in Shouchun would be reduced, but also meant that in the future, in addition to Shuqi Powder, there would be another more efficient prescription for malaria with easier-to-find materials.
"I don't deserve Mr. Zhang's praise... It just happened to be a coincidence, a coincidence. However, I still need to pay attention to the hygiene of the sanatorium area, clean up stagnant water, and prevent the breeding of mosquitoes. We need to continue to keep an eye on it." Bai Tu seemed uninterested.
Malaria is mainly transmitted by mosquitoes, so the effect of isolation is actually not that great. The main thing is to repel mosquitoes and maintain hygiene.
"Mr. Bai, are you worried about the efficacy of Artemisia annua water? Well, it is a blessing in disguise to have the current effect. Even if there is enough Shuqi powder, it will not be better than it is now." Zhang Zhongjing comforted him.
Sure enough, a handful of Artemisia annua and two liters of water were added, and the juice was minced and drunk - such a rough extraction had limited effect.
Otherwise, malaria would not have continued to flourish for more than a thousand years...
Mr. Zhang also knew that boiling Artemisia annua was useless. The times and technology limited the means of cold extraction, so only manual "raw extraction" was possible.
"I have a student who thinks quickly. Maybe he can find a solution," Bai Tu said.
He was still waiting for Pang Tong's reply, although... intellectually, Bai Tu already understood that Pang Tong should also be "desperate" about this.
After all, how can ether, gasoline and the like be produced nowadays?
Otherwise, Yuan Shu would have been blown to the sky by him long ago, and there would be no question of whether he had malaria or not...
But still holding on to some sentimental fantasies, Bai Tu was still looking forward to Pang Tong's reply.
Zhang Zhongjing did not try to persuade him anymore. Instead, he looked at Bai Tu with satisfaction - if he was a doctor or a disciple of Zhang, he would definitely change Bai Tu's mentality. After all, doctors are not omnipotent. It is their duty to treat every patient wholeheartedly. But if he has such a big reaction to every patient who cannot be cured, then he will not be far from retiring.
Modern medicine cannot save all patients, let alone in the late Eastern Han Dynasty? Just do your best and leave the rest to fate...
However, Bai Tu was a local lord, so Zhang Zhongjing hoped that Bai Tu could maintain his position, just like King Xuan of Qi saw his men slaughtering a cow for sacrifice, and saw the cow trembling, and felt distressed... and asked his men to slaughter a sheep instead.
It seems hypocritical to modern people, and it seems stingy to people at that time. After all, sheep were much cheaper than cattle at that time...
But after hearing about this, Mencius gave a positive affirmation, believing that this was a manifestation of King Xuan of Qi's "kindness".
Just like a gentleman can eat meat but is unwilling to kill chickens and sheep with his own hands. It seems hypocritical in theory, but the ability to produce this kind of "unwillingness" is precisely because there is "benevolence" in one's heart. Even if it seems stupid sometimes, it is better than having nothing.
What's more, Shouchun has nearly half of the city's population living there. If they really do the math and find out that the proportion of injured people is lower than expected, they will be happy... This 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 vibrated. It was the reply from Pang Tong. Bai Tu quickly apologized to Mr. Zhang and began to check.
When Bai Tu saw the schematic diagram Pang Tong drew for him, he was confused - why did it look like a supercritical fluid extraction device?
Supercritical fluid extraction can be said to be the most efficient and purest cold extraction method, but in the late Eastern Han Dynasty, it was less reliable than ether and gasoline...
In principle, it is to select those special gases or liquids, which will behave as supercritical fluids under special pressure conditions, that is, they have some properties of both gas and liquid. In this state, the substance to be extracted will be dissolved out, and then return to normal. The supercritical fluid will turn back into ordinary gas or liquid, leaving only the extract.
With low residual dissolved matter and high efficiency, it can be said to be the fighter among modern cold brewing technology, but... it is extremely expensive.
Generally, carbon dioxide can be chosen as this fluid material, but it needs to be pressurized several hundred times the atmospheric pressure to make it show the state of supercritical fluid, and the whole equipment is extremely expensive.
Although Bai Tu didn't understand it very well, having only come across it when he was ghostwriting papers, he took a look at the information when he sent it to Pang Tong not long ago, so he recognized the equipment at a glance. It was very similar to the supercritical fluid extraction equipment!
This was not only expensive in the late Eastern Han Dynasty... Where could one add hundreds of atmospheres of pressure to the white map?
However, as he continued to look down, Bai Tu was stunned by Pang Tong's idea...
The world of Cheng Ji is very different from the world before Bai Tu crossed over, but... for a long time, Bai Tu had not discovered any difference in civilian technology, so he had always ignored this point.
However, as a native "local" who was born and raised here and had a very high IQ and open-minded thinking, Pang Tong discovered a completely new method from the advanced teaching materials given to him by Bai Tu.
Although the textbook was beyond the syllabus, Pang Tong already understood the basic principles, so he found a substitute for supercritical fluid - internal breath.
A very mysterious thing, Lu Bu had told Bai Tu before that very few of the basic exercises for warriors include some breathing rules, and a large part of the exercises attached to the armor will also have corresponding parts.
Although the warriors in the world of Cheng Ji mainly practice "dynamic exercises", that is, exercise rather than meditation, a magical power will be generated through breathing, which can be used to charge armor at ordinary times.
Generally speaking, in order to consume gilded armor, the user must have a certain amount of internal energy to drive it, and Bai Tu... is stuck at this step.
If there is no section on breathing exercises in the instruction manual of the wooden and stone armor, it means that the user is not qualified and must seek advice from others and improve his techniques before he can make further progress.
In theory, internal breath should be a conceptual product at the "idealistic" level. It cannot be seen or touched, and is neither gas nor liquid.
It doesn't mean that after the internal energy is transformed into liquid, there will be a new set of "blood vessels" in the body to flow the internal energy. It's just that when using it , it can not only charge the armor, but also affect reality. This conflicts with many of the principles that Bai Tu gave to Pang Tong.
So Pang Tong had already done some research and ideas in this regard, and he also had a best "test subject" - Zhou Tai.
Although Zhou Tai is still a step away from the gold and jade armor, he is the one under Bai Tu who is closest to the gold and jade armor. Moreover, his body is different from that of ordinary people, and even his pure combat power is not inferior to Gao Shun who is wearing the gold and jade armor.
Zhou Tai's internal energy has become "liquid", of course... it is only liquid in an abstract sense. When a person drives the armor until his internal energy is exhausted, his weight will not change compared to his normal state.
Pang Tong was very curious about this state, and had done some research and experiments before. He eventually discovered that this abstract liquid could be released when a warrior concentrated, just like the "non-existent" internal breath, which could knock down trees or even blow a hole in the ground when released.
In the end, Pang Tong came to the conclusion that when the inner breath is in the warrior's body, it is between existence and non-existence, and when the warrior releases it, it has certain physical properties...
In the absence of sufficient information, Pang Tong established a hypothesis that "inner breath" exists as the will of the warrior. When this will is recognized by external objects in the world, it will exhibit the same properties as real matter in the outside world.
When the outside world does not recognize the warrior's will, the "internal breath" does not exist - but this violates the law of conservation of matter, so Pang Tong changed his thinking. It is not "non-existence", but a superposition state between "existence and non-existence".
To extend this further, Pang Tong conducted a hypothetical experiment.
If a wild goldfish caught by Gan Ning is placed in a bucket of seawater, and the bucket is covered with a wooden board with a few kilograms of salt on it, then a general with his inner energy revealed can strike the board from a distance, and the board will break, and the goldfish will die because of the high concentration of seawater. If a general with his inner energy is not revealed, he will not be able to strike through the board from a distance, and the goldfish will survive...
In other words, if it were a general who didn't know whether his will was recognized, the goldfish would be in a superposition state of death and immortality. This was the famous hypothesis later known as "Pang Tong's wild goldfish."
Bai Tu was not interested in Pang Tong's big goldfish, but... Pang Tong also explained one point in the letter, that is, "internal breath" can be used as "supercritical fluid".
There is no need for hundreds of air pressures to create supercritical conditions. As long as a warrior can control the liquefaction and release of , it can be used as a substitute for supercritical fluid, or... should this be considered "internal breath fluid"?
The name is not important. What is important is that Pang Tong not only simulated it with special tactics, but also actually experimented it in Wujun. As the provider of internal fluid, Zhou Tai can use the juice extracted from Artemisia annua with high efficiency!
Pang Tong even felt that if further research was conducted, it might be possible to control the nature of the internal energy through the warrior himself to specifically separate the effective substances therein, but... time was tight and there was no time to conduct such an in-depth study.
After Bai Tu understood, he immediately started to organize the construction of extraction equipment in Shouchun, and then asked Taishi Ci to try it...
The liquefaction of internal breath is the basis for the extraction of "internal breath fluid". Apart from Zhou Tai, there should be only a few generals who can achieve this step.
At the same time, Bai Tu immediately sent people to notify Lu Bu and Sun Ce who were still in Runan.
Pang Tong had already succeeded in Wujun, which showed that this method was feasible. However...it was not so easy to liquefy the internal energy, manifest it only in liquid state, and recover it after extraction.
One day later, Bai Tu had built the equipment with all his manpower. It looked like a supercritical fluid extraction device, but in fact it was very "pocket-sized". Taishi Ci could hold both ends of it with his left and right hands, one side was the inlet, and the other side was the outlet. If the internal energy was not recovered, Taishi Ci would be exhausted in a short while.
Two days later... Taishi Ci successfully extracted two liters of essence, but seven or eight devices were destroyed. Fortunately, Bai Tu has been organizing people to produce it!
This thing is more dangerous than ether. Although it is non-flammable, it can easily become aggressive and blow up equipment...
Taishi Ci was also a little embarrassed. Usually he tended to be a skilled 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 had a special physique and his strength was not yet at the level of General Jin Yu. His internal energy was also weaker after being liquefied. Therefore, judging from the success rate given by Pang Tong, he even exceeded Taishi Ci.
At this time, Lu Bu and Sun Ce had also returned overnight.
This extract is indeed useful, but Taishi Ci alone cannot keep up with the efficiency. Now Bai Tu can only look forward to his adoptive father and second brother...
