Two, three, four... Soon, Li Ang had used eleven syringes to complete the first round of injections.
But he didn’t start the second round right away; instead, he waited for a little while, for the steam sterilization of the syringes to finish and for the reactions of the military horses after the injections.
Not a single one of the horses showed any signs of discomfort. In fact, once the panic from being pricked by the needle subsided, all the horses that had received the eye drops beca much less irritable, and the red veins in their eyes gradually receded. Effective. Li Ang gently nodded his head.
The tissue fluid from pig eyeballs contains over ten different amino acids, including lysine, glutamic acid, and C amino acid, which can enhance the regenerative process of the eyeball, strengthen the body’s ability to resist disease, reduce eye pressure, and relieve eye pain. So, in the Otherworld he rembered, extracts from pig, cow, and sheep eyes were used to produce Eye Amide Peptide Injection Liquid. This liquid was used to treat vitreous opacity, non-purulent keratitis, scleritis, iritis, and other eye conditions.
To produce a dication with similar effects, he first placed the collected pig eyeball fluid in an environnt of around 2 degrees Celsius—inside a pile of ice made from saltpetre—for five days of refrigeration. After five days, he then added an equal amount of physiological saline to dilute it, stirred thoroughly, and let it soak for an hour. Next, he heated and boiled the pig eyeball solution for an hour to coagulate the proteins inside, and then imdiately cooled it down using an ice-salt thod to remove the proteins. After obtaining a clearer solution, he filtered it several tis through a double layer of gauze to clean out the impurities. He boiled and heated the solution again, cooled it again using the ice-salt thod to remove the proteins, and filtered it again. After repeating these steps several tis, he obtained a transparent and clear pure liquid. Finally, he put the transparent clear liquid into a container and boiled it at 100 degrees Celsius for forty minutes to sterilize it, ultimately producing a pure pig eyeball fluid extract without any flocculent matter or impurities—the only effective eye drops in this era.
The whole process, in the eyes of Chai Cuiqiao, the only one in the know, was simply like alchemy. And at this mont, in the eyes of the crowd gathered at the entrance of the Pasture Supervisory Office, Li Ang’s image was not much different from that of an Alchemist.
"How can such a thick needle be injected into the orbits of the military horses without blinding them? There’s hardly any blood."
"How did he manage that?"
"Father, look, the eyes of those horses don’t seem so red anymore."
Listening to the crowd’s murmurs, Li Ang smiled slightly and silently recalled information from the mory Hall. Pig eyeball extracts had a significant therapeutic effect on acute conjunctivitis, keratitis, and traumatic corneal hemorrhage in large livestock. They were, on average, 80% effective against chronic keratitis, keratopathy, and periodic ophthalmia, with 20% of cases showing improvent, and the long-term therapeutic effect was stable.
Hmm... now that I think about it, I’m clearly a surgeon, so why was I reading veterinary articles...
Musing to himself, Li Ang’s mind involuntarily filled with even more information:
[Diagnosis and treatnt of bovine gastroenteritis]
[Treatnt and prevention of lamb clostridial dysentery]
[Diagnosis and integrated prevention and control of foot-and-mouth disease in livestock]
Well then.
Li Ang’s facial expression was quite interesting. Surely, I can’t be switching careers to beco a veterinarian, can I? Could I actually consider becoming prosperous through animal husbandry? Make my first pot of gold by raising poultry and livestock, knock on the doors of the Academic Palace with a fortune, and from then on embark on the path of Cultivation, becoming a transcendent Cultivator... No, this style clashes too much. It’s not like I’m filming "Wealth Building Guide."
Li Ang kept mocking inwardly, but on the surface, he remained serene, with the deanor of a master.
Once the syringes were sterilized, he began the second round of injections. It wasn’t until afternoon that he had treated all one hundred-plus military horses.
During this ti, people in the crowd ca and went. Every ti Li Ang plunged the syringe into the eye socket of a military horse, loud cheers would erupt from around—far more interesting than watching a pig being slaughtered. And Li Ang’s needlework was precise and swift, never making a mistake, and even looked sowhat cool and dashing, except for tis when he had to stand on a stool to inject the taller horses because he was not tall enough.
Xun Mujian watched the warhorses, whose eye conditions had obviously improved, and the sorrow from the past few days vanished. He looked rejuvenated and hurriedly had his n bring over the fifteen most high-grade and valuable noble horses from the stable.
Li Ang treated them all equally, efficiently completing the injections. It wasn’t until he began cleaning the syringes and packing up his wooden box that Xun Mujian, still seeming dazed, pointed at the horses and muttered, "Doctor Li, is that... is that it?"
"That’s it."
Li Ang waved his hand casually and said softly to Xun Mujian, "Pasture Supervisor, about the paynt we discussed earlier—one hundred strings of coins—I would like it in Yu Country banknotes. Please have Wang Yashi deliver it to my house later."
Xun Mujian nodded and said, "Yes, yes, certainly."
Seeing the other party agree, Li Ang turned to the onlooking crowd and announced, "Fellow townspeople and elders, I am Li Ang, the owner of Security Hall dical clinic on the west bank of Yizhou Bridge. Tomorrow, Security Hall will reopen for business, specializing in treating trauma and bone injuries. The consultation fee for all patients will be fixed at twenty wen, twenty wen only, for a limited ti of three days. Please lend your support! Security Hall dical clinic on the west bank of Yizhou Bridge!"
"Great!"
The enthusiastic crowd that had watched the novel performance shouted in agreent. At this point, if Li Ang brought out an iron plate, people might even throw flat money into it.
"Humph."
In a corner of the crowd, Yu Miaoshui’s face was gloomy as he flung his sleeve and strode away. His assistant Yu Liu hurriedly followed him. He wanted to console him but did not know what to say.
This kid is really sothing else, Yu Miaoshui muttered to himself, his expression dark, his paper fan creaking in his hands.
Yu Liu quietly suggested, "Sir, shall I find soone to publish an article in the Yizhou newspaper, saying that his thod of treating military horses’ eyes with dead pigs’ eyes is akin to Evil?"
"What Evil? The principle of treating with corresponding parts is in the ’Inner Canon of the Yellow Emperor, Plain Questions, Great Treatise on the Harmony of the Five Phases.’ Eating pig kidneys to nourish kidneys, eating fish eyes to improve vision, and bone soup to strengthen bones—these are all common dical principles. Moreover, he only treated horses, not humans. If the military horses are fine, then there’s no fault to find."
Yu Miaoshui replied darkly, "Furthermore, he has so many witnesses and even the endorsent of the Pasture Supervisory Office. If you claim he practices Evil, the Pasture Supervisory Office would be the first to disagree; they’d go to extres against you."
"So what do we do...?"
"Let’s wait until tomorrow."
Yu Miaoshui stopped walking and turned to look toward the alley from which Yizhou citizens were continually erging. He shook his folding fan with feigned nonchalance, creating a breeze, and said coldly, Running a dical clinic... isn’t as easy as it looks...
