"Is this the effect of cement?"
Fiora immediately realized the immense utility of this material. Her eyes widened, filled with an expression of disbelief.
"It's incredible! Yesterday it was soft like mud, and after just one night, it's as hard as rock. With this magical stuff, as long as there are enough stones, building city walls and houses can be done as quickly as possible, right? This speed is simply like magic!"
Link smiled and nodded, his eyes full of longing.
"That's right, and this is just the beginning. Later, when we can smelt steel, if we insert rebar into the cement before it sets, it will be even stronger. Cement houses built with reinforced concrete, let alone decades, will not be at risk of collapsing for hundreds of years. By then, we will have indestructible buildings, and we will no longer have to worry about the onslaught of storms and wars."
Technology is the primary productive force; this is not just an empty phrase.
It is like a magical key that can open the door to prosperity and power, leading the world into a whole new era.
It was really great to have recruited Hanna!
Mentioning Hanna, Link immediately turned his gaze to the Soldier beside him and asked, "Where is Hanna? Why isn't she here yet?"
Indeed, it had been a while, and Link still hadn't seen Hanna.
By common sense, she should be more concerned about this matter than anyone else.
"Lord, Miss Hanna didn't return to the City Lord's Mansion last night at all. We brought her dinner and supper. She stayed up all night in the workshop and only finally collapsed onto the table and fell asleep in the early hours of the morning."
The Soldier said, pointing to the small room deeper inside the workshop, and reported to Link in a lowered voice.
Link gently pushed open the door, and sure enough, Hanna, who hadn't slept all night, was sleeping soundly on the table, her hair disheveled around her cheeks.
Link looked around the room, seeing various bottles and jars scattered about. The air was filled with a rich, mellow scent of alcohol. It seemed Hanna was in the midst of distillation.
Gazing at these peculiar devices cleverly constructed from bottles and jars, Link's mind instantly recalled the distillation equipment used in chemistry lab classes of the past. Those precise instruments and complex operating procedures bore a striking resemblance to these simple yet ingenious devices before him.
"Is this for making high-proof alcohol and ethanol?" Link murmured to himself.
At this moment, Hanna, hearing the commotion, slowly awoke. She groggily lifted her head, saw Link before her, and mumbled dazedly, "Ugh… Lord Link?"
Link frowned, his tone carrying a hint of reproach: "Didn't I tell you yesterday to go back and rest early? Why are you so disobedient?"
Hanna rubbed her eyes, trying to clear her head, and said excitedly, "I want to make the things you need as quickly as possible! Look at this, this is the high-proof alcohol I purified from ale last night. And this here is alcohol that has been distilled three times, with a purity of about 90%..."
"Alright, alright, this isn't the time to tell me all this. Go back to sleep quickly. If you wear yourself out, how will you continue to work?"
Link gently patted her head, and without waiting for her to finish, immediately turned and called Fiora in from outside the door, "Fiora, quickly take Hanna back to get some good rest. Don't let her overwork herself!"
"Yes, My Lord!" Fiora responded respectfully, then stepped forward and gently helped Hanna up.
Link looked at Hanna and said gently, "Hanna, when you wake up from your sleep, come and report to me when you are refreshed."
Hanna nodded slightly. Although still a bit reluctant, she knew she indeed needed rest, so she softly replied, "Alright, Lord Link."
...By the time Hanna woke up, it was already afternoon.
After waking, Hanna eagerly retrieved the high-proof alcohol and pure alcohol she had meticulously refined last night and hurried to find Link.
In Hanna's plan, the high-proof alcohol could be sold.
But what was truly crucial was the pure alcohol.
According to Hanna, the alcohol currently extracted had a purity hovering around 90%.
To further increase its purity, quicklime needed to be added during the distillation process.
Afterward, mixing the purified alcohol with distilled water in a 1:3 ratio would yield medical disinfectant alcohol.
The importance of this medical alcohol lay in its ability to coagulate proteins, thereby rendering them inactive, causing bacteria to have nowhere to hide and leading to their demise, ultimately achieving the miraculous effect of sterilization and disinfection.
In the field of medieval medicine, it was undoubtedly a "holy water for surgical wound disinfection."
And considering the previously drawn penicillin for injection, with both internal and external treatments, the threat of infection would be greatly reduced, making it an excellent medical combination!
Upon hearing this, Link immediately made a decisive choice.
The raw material for refining pure alcohol would be the cheapest ale.
By purchasing it in bulk directly from the merchant guild, the tedious steps of making distiller's yeast and brewing would be eliminated, saving time and cost.
