From Robinson Crusoe

Chapter 94 Albendazole
time flies.

Since the earthquake, Chen Zhou's life has become a series of tasks on the schedule, all of which are progressing steadily.

The prototype of the water mill was completed on June 6.

Chen Zhou prepared three styles for it.

The smallest one of them uses foot pedal to work, which is inefficient and can be used when processing less grain. However, because it does not use water power, it is obviously not appropriate to call this machine a water-based pestle. Perhaps it would be more appropriate to call it a "foot-pedaled pestle."

The medium-sized one is a standard water mill, which is placed in the river channel and uses water power to drive the impellers. It can process grain 24 hours a day without interruption, and the water power is relatively stable. It is the most practical of the three styles.

The largest and most complex one is the wind-driven crushing tool, which is still at the drawing board stage.

In Chen Zhou's conception, this largest wind-powered pestle, like the earthen rice huller, has an interface for connecting to windmill power.

Its pestle head will be made of cut hard stone, while the pestle rod, pestle frame and base will be made of ironwood boards to extend the service life of the entire tool.

In the future, after the windmill is built, this wind-powered pestle can not only be used to process rice, but also to grind barley and wheat, or process some lower hardness ores, coarse salt grains, etc.

Although wind power is not as stable as water power, it has one advantage: it will not be restricted by water.

Chen Zhou planned to build the windmill on the sunny hillside, where there was wind all year round and it was very close to the cave dwelling.

After the crops are harvested and dried on the platform, they can be husked and sieved out of the rice husks and then sent directly to the windmill for processing using stone mills or wind-powered pestles. The entire grain processing process can be completed in three days at most.

Of course, if he relies solely on his own strength and energy, it might take more than a decade to realize this beautiful vision.

A large and complex mill requires an astronomical amount of manpower and material resources.

In medieval Europe, a miller who owned a windmill would be looked up to even by noble lords.

This production tool, which takes ordinary workers, carpenters, stonemasons, bricklayers, blacksmiths and old architects several months to complete, becomes a small cash cow once it is built.

Compared with the cooperation of everyone, Chen Zhou, alone, even if he had a better design and a more convenient construction method, could not exceed the limits of human power.

And even if he built the windmill, the subsequent maintenance of its internal components for more than a decade would be enough to overwhelm him.

……

But at present, the windmill is still a very distant thing.

After the prototype was completed and its function was verified through practical tests, Chen Zhou devoted all his efforts to the manufacture of the pedal pestle.

……

While processing the pedal pestle parts, he often felt proud of his bold idea.

Without the help of the "space-time cutter", he would not be able to cut so many smooth wooden boards by his own ability. It would take him an unknown amount of time to make these complex machines.

Compared to an axe, a lighter, a hiking bag, a set of ear picks, toilet paper or bearings removed from an ergonomic chair, this cutting machine, which can only be used once every fifteen days, is the biggest help in the challenge.

However, the processing process is mixed with joy and sorrow. Sufficient wooden boards are a godsend, but the tools used to carve and saw the boards will suffer wear and tear.

Solid tools like chisels and hammers can still be used with a little care, but the teeth on a hand saw become duller and duller.

From boarding the ship to making a raft, and then landing on the island.

In total, this hand saw has cut through countless pieces of wood. In less than a year, it has completed work that a normal saw would probably take three years to complete.

Chen Zhou once used a grindstone to carefully polish the teeth of the saw, but this could only make it sharper but could not make up for the loss of metal in the saw body.

According to his estimation, if the saw continues to be used at this intensity, it will most likely be scrapped before December.

The carpenter's tools include three saws, two short saws and one long saw. This saw is the most handy and the only one that can saw trees with a diameter of more than one meter.

If it is damaged, many future tasks will be difficult to carry out.

……

To prepare for a rainy day, Chen Zhou came up with a bold idea:

He wanted to cut the armrests and metal tubes on the edge of the backrest of the titanium alloy ergonomic chair, then adjust the angle and cut out the teeth little by little for future use.

To prove his point, he even calculated how long it would take to cut a hand saw.

The result is disappointing. The pitch of a medium-toothed saw blade is about 1.2 mm, and a one-meter-long saw blade must have at least 72 teeth.

If you place the saw blade at the four corners of a square cut, you will end up with a failed tooth every time.

Under ideal circumstances and without mistakes, it would take 1080 days, or nearly three years, to cut a saw blade that is barely usable.

Moreover, this is a "super low-quality saw blade" that I don't know if it is good to use, and the tooth pitch may not meet the standards at all.

If something unexpected happens during the cutting process, such as a gust of wind or rain, which affects the placement of the metal strips on the beach, the manufacturing time will be extended.

All in all, his new bold idea was simply impractical.

In comparison, it seems more reliable to build a water-powered grinder by the river, sharpen a saw blade by yourself, or build a charcoal kiln and furnace to recycle scrap metal to make saw blades.

……

In any case, the day when the saw is actually worn out has not yet come. As long as the teeth can still cut through wood fibers, it will continue to work for Chen Zhou.

In a blink of an eye, it is June 6th, and the seventeenth mysterious reward has arrived as expected.

This time the reward is different from previous ones. The size has been severely reduced and it is completely different from recent rewards.

After sorting and moving the wooden planks and bricks, looking at the empty reward center, Chen Zhou almost thought that the rewards had been stolen.

Because this reward has no outer packaging, it is a completely exposed white plastic bottle with the color print facing downwards, and the back is covered by fine sand blown by the wind, so you won't notice it unless you look carefully.

But don’t be fooled by its small size, this reward is really not garbage like a mobile phone case or electronic wooden fish.

But it was one of the supplies Chen Zhou needed most - medicine.

This is a bottle of veterinary medicine called Albendazole Tablets, with a full bottle of 100 tablets.

According to the description on the bottle, this medicine is mainly used for broad-spectrum deworming and has significant effects on parasite eggs, nematodes, tapeworms, flukes and roundworms.

As can be seen from the dosage and usage, this medicine is for internal use and can be eaten by cattle, sheep, horses, pigs, dogs and poultry. Sheep should be fed 0.2 to 0.3 tablets per kilogram, and dogs should be fed 0.5 to 1 tablet per kilogram, once a week.

On an isolated island in the 17th century, it was inevitable to eat wild animals, such as wild geese, frogs or fish.

If you are careless during the cooking process and fail to stew the game, or accidentally eat fruit with parasite eggs, having a bottle of anthelmintic medicine like this can give you peace of mind.

Unfortunately, although this whole bottle of 100 tablets looks like a lot, it is actually not enough to eat.

At present, Lai Fu's weight is approaching 45 kilograms, which means that he needs to take at least 22 tablets at a time, and be fed once every week. A total of 44 tablets are needed for deworming, and half of this bottle of medicine is consumed.

Chen Zhou couldn't estimate his own weight. Comparing his current muscle dimensions with those before the challenge began, he felt that he was at least 160 pounds.

The veterinary drug instructions did not specify the dosage for humans. He conservatively estimated that he would have to take at least a similar dose as Lai Fu in order for the drug to be effective.

With this calculation, this bottle of medicine is only enough for the two of them to get rid of insects once. If Xiao Huihui, Grapes and the goat are added, it will still be far from enough.

"Damn it, he's so generous when he shouldn't be, and so stingy when he should be.

We gave away an ergonomic chair worth more than 100,000 yuan, but you only gave me this much insect repellent that costs only a few dozen yuan a bottle. Would it be a big loss if you just sent a box?"

Holding the medicine bottle, Chen Zhou gritted his teeth.

After reading the instructions and usage and dosage, he did not forget to check the shelf life.

Coincidentally, the production date of this bottle of medicine is exactly the same as that of the box of cans, both September 2025, 9, but the shelf life is much shorter than that of the cans, only two years.

Feeling that there was nothing wrong with his health recently, including no loss of appetite, sudden abdominal pain or diarrhea, and no parasites or worm eggs, Chen Zhou decided to keep the bottle of medicine and take it when he showed symptoms of suspected parasitic infection.

Lai Fu was also healthy. Within a few months, he ate everything with relish, was full of energy, and gained weight.

Chen Zhou often pays attention to its feces and has not found any parasites, so it does not need to take the medicine for the time being.

Without medicine, parasitic diseases are difficult to treat. Even though a small bottle of medicine is not as valuable as a caster of an ergonomic chair, it can be a life-saving thing when it comes to the critical moment.

In order to properly keep the small medicine bottle, Chen Zhou did not even dare to unscrew the lid or poke open the aluminum foil inside, for fear of affecting the shelf life of the medicine.
