Chapter 12 Veterinarian
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 became 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 remembered, 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 medication with similar effects, he first placed the collected pig eyeball fluid in an environment 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 immediately cooled it down using an ice-salt method to remove the proteins. After obtaining a clearer solution, he filtered it several times 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 method to remove the proteins, and filtered it again. After repeating these steps several times, 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 moment, 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 Memory 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 improvement, and the long-term therapeutic effect was stable.
