Global colonization began with Ming Dynasty pirates.

After Doctor Chen rechecked the pulse and confirmed that the unconsciousness was only temporary, the people in the room finally felt a little relieved.

Lin Hao left the room with a heavy expression.

From any perspective, I cannot accept this outcome.

Emotionally speaking, my father has always been very good to me since I was a child. Even when I gave up my studies and chose to pursue martial arts instead of literature, he would only sigh and ultimately respect my decision.

From childhood to adulthood, whatever he wanted, he would do everything he could to get it. If he wanted to study, he would spend a lot of money to hire the best teacher in the county. If he wanted to sail, he would immediately form a maritime merchant fleet. If he wanted to cultivate a team, he would immediately arrange for people to recruit homeless youths.

It can be said that even the most doting parents in later generations did not do as much as he did.

Moreover, with his father alive, he is the rightful heir of the Lin family and can confidently arrange all personnel matters. However, if his father were gone, anyone could become the heir while the old man is still alive, depending entirely on the old man's own mood.

Although the old man is supporting me now, who can guarantee that this situation won't change?

Without their father as a pillar of support, the family blueprint they envisioned would truly remain just a blueprint, with the risks increased far too much. After all, not everyone can remain clear-headed when faced with the choice between future benefits and immediate gains.

As long as there is such a possibility, Lin Hao must take precautions, and once this begins, the internal strife within the family will not stop.

"Sigh, it's so hard to get anything done." Lin Hao sighed, then said to a middle-aged man outside the room, "Uncle De, could you please prepare a lot of alcohol and some utensils for me?"

Lin Hao then explained the specific supplies to him one by one.

At this point, there was no other way but to try everything.

The first thing to do is to distill the liquor to obtain a high concentration of alcohol. Although an infection has already started, cleaning the wound with alcohol can at least kill the bacteria on the surface.

As for the pain caused by applying alcohol to the wound, Lin Hao was confident that his father's tough physique would be fine. He could always tie him up if necessary.

"Yes, young master, is there anything else?"

Uncle De was a middle-aged man in his early thirties. He was actually a cousin of the Lin family, and a cousin of Lin Hao's father. He couldn't make a living in his hometown, so he came to stay with Lin's grandfather.

"Prepare another 5 catties of garlic for me. Have someone peel and wash it for me, and make sure it's not crushed."

Uncle De acted quickly, and in no time, he and several people had prepared the supplies that Lin Hao had instructed. Then Lin Hao found an empty house and began to design the entire distillation process according to his memory.

If it's just conventional distillation, under these conditions, the concentration can only reach about 40%-60%. This is because traditional top-mounted distillation uses water cooling, which causes the water temperature to rise quickly but has limited cooling efficiency. Over time, the water vapor will also evaporate and condense, reducing the alcohol concentration.

To obtain high-concentration alcohol completely, the entire process must be redesigned and a more reasonable condensation facility must be built. However, Lin Hao's current time does not allow for redesigning and building the equipment, so he can only use the traditional method to obtain alcohol, which will certainly not be concentrated enough.

Low-concentration alcohol has a very poor sterilization effect and falls far short of the desired effect.

However, there are ways to cheat. The first is to only collect the first few tens of seconds to a minute after the wine begins to flow. At this time, the alcohol concentration is the highest.

As for the remaining wine, it can be redistilled after cooling, which will greatly reduce the presence of water vapor.

The second method is to add ice to the top pot, which greatly increases the cooling rate. This allows for the production of a large amount of high-concentration alcohol during the initial period when only alcohol evaporates.

As for ice water, that's simple; you can easily make large quantities of ice using saltpeter.

The third one is quite simple: repeated distillation to increase the concentration.

After the facilities were set up and the precautions were explained to the group, the alcohol distillation process finally began half an hour later.

As distillation continued, the smell of alcohol in the room grew stronger. After an hour, and after several distillations to obtain the first distillate, a small bowl of high-concentration alcohol was finally obtained.

Lin Hao couldn't precisely measure the alcohol concentration, but he guessed it was over 70%. That was enough; 70% alcohol concentration could achieve a good sterilization effect, and its penetration ability was also very good. Too high a concentration would cause the surface proteins of bacteria to coagulate rapidly, forming a protective film that would prevent the alcohol from penetrating deep enough to kill the bacteria.

"Keep making alcohol, don't stop, I need more."

After instructing on the production of the alcohol, another item Lin Hao needed was also delivered.

That is a large quantity of peeled and washed garlic.

In this era, penicillin is too complicated, and its production and purification are very troublesome. If you want to cure inflammation, the only remaining methods besides alcohol are allicin.

"Luckily, I read a lot of online novels in my past life, otherwise I really wouldn't be able to cope now."

If we're talking about the most convenient anti-inflammatory and antibacterial agent in ancient times, allicin has to be it. Allicin has inhibitory and bactericidal effects on various viruses, cocci, and bacilli, as well as fungal infections and some parasites.

However, compared to penicillin, a stable antibiotic, allicin is far less stable and decomposes when exposed to high temperatures, but its effects are still strong, and its production method is very convenient.

When fresh garlic is crushed, the alliinase in the garlic is activated by the impact, which then catalyzes the formation of allicin from the alliin in the garlic.

In other words, simply crushing garlic and letting it sit for a while yields the most powerful antibiotic of our time.

Allicin is slightly soluble in water but readily soluble in organic solvents such as alcohol. Simply soak minced garlic in alcohol and let it stand to obtain a usable allicin solvent.

Lin Hao personally placed the garlic into clean containers and carefully crushed it. After letting it stand for more than ten minutes, he poured in alcohol to extract it.

Both allicin and alcohol are strong irritants; you can imagine how uncomfortable it would feel to apply them together to a wound.

Whether the medicine would make his father better or not was another matter, but Lin Hao always felt that his relationship with his father was in danger of breaking down.

Fortunately, it was her own father; if it had been used on someone else, people would probably have suspected it was an act of revenge.

"Phew~ It's finally done."

Lin Hao prepared the last batch of allicin, which he divided into two types.

For external application, soak in high-concentration alcohol; for internal use, soak in regular spirits.

Alcohol plus allicin, taken internally and applied externally, is designed for a saturation attack. Lin Hao didn't believe that bacteria from this era could be stronger than those from later generations that had been screened out by countless antibiotics.

"Uncle De, take the things, we're going to apply medicine to Father."

"This...can this really work?" Uncle De was clearly unsure. He had previously thought Lin Hao was planning to make wine for business, but when he heard it was for saving lives, he was stunned. He had never heard of wine and garlic being able to save lives.

"Of course, Uncle De, you have to believe in science!"
