When the bark of the magic tree was being sold, two deer carts were taken, and naturally two carts of sulfur and saltpeter were hauled back.
In other words, although Yaro used his army horse to drag away one cart, he still had a cart full of sulfur and saltpeter left in the hunter's courtyard outside Laner Village.
In addition to these ordinary materials, there is also a mutilated body hidden in a wooden house in the small courtyard.
That's right, it's the werewolf corpse obtained from the witcher.
According to Yaro's previous plan, he planned to dissect the corpse when he came back, and it would be best to make a microscope to carefully examine the werewolf's cell structure.
But things have changed now, and there is no time to dissect a werewolf in the near future.
In order to prevent the corpse from decaying, Yaro took some saltpeter from the wooden cart, put it into a wooden barrel, and prepared to use the saltpeter to make ice to cool down the wolf body.
Yaluo added water and saltpeter, and then soaked the entire humanoid wolf body in it.
During the whole process, there was no emotion in his heart, just like he was simply handling a domestic animal.
Pressing his furry thighs hard into the saltpeter water, Yaro inexplicably thought of the elk being hunted and those little amber elves.
"Werewolves are more human than elk and elves. Werewolves can even take on human appearance. Why don't you feel any emotion when you kill them?"
Maybe it has something to do with that experience in childhood and my innate aversion to werewolves?
Perhaps, it has something to do with the long-term teachings given by my grandfather in front of the blood-stained test bench?
Or maybe, when I was in the academy, I heard that too many instructors used students for experiments?
Yaro quickly thought of the answer.
"When I killed those human villains, I didn't have any mood swings at all!"
Punishing evil is Yang Shan.
If there is one less werewolf that preys on humans in the world, we will be safer.
Werewolves are naturally cannibalistic and have nothing to do with good or evil?
Yaro has always been a human being in his past and present lives!
Cannibalism is the greatest evil to Yaro!
"The so-called evil can also be understood as the threats that may arise to oneself in the world?"
"The so-called kindness can be understood as the potential hidden goodwill towards oneself in the world?"
Starting from yourself may be cold or ruthless, but it is the most sincere emotion.
In a previous life, a man accidentally entered a tiger park to escape a fare by jumping over a wall, and was bitten on the head by a tiger. However, the zoo immediately killed the man-eating tiger.
Are tigers pitiful?
Poor, but worthy of death!
Why did the tigers in the previous world become endangered animals?
When the country was founded, due to the long-term war, people reclaimed the mountains and forests in order to have food and clothing. As a result, the animals on the mountains were homeless. They went down the mountains to waste food and were hunted by people.
Due to lack of prey, tigers can only go down the mountain to eat people.
Due to the frequent incidents of evil tigers cannibalizing people, the people were panicked, so the country in the past life encouraged hunting of tigers.
In more than ten years, the tigers have become extinct.
For the development of science and technology, are the laboratory mice pitiful?
In order to fight the epidemic, are the primates 'rhesus monkeys' pitiful?
"Will those who pity the werewolf pity the dog?"
“Will those who pity dogs pity cows?”
“Poor pig that pities the cow?”
or……
“Do those who pity animals pity insects?”
“Will those who pity insects pity plants?”
"Will those who pity plants pity inorganic matter?"
In this world, ruthless water and fire can turn into life. Those ruthless flames that are extinguished, don't they eliminate the possibility of a life?
Guanzi said: "The warehouse is solid, and you know the etiquette."
Yaro will never be stingy with his kindness to those who are not a threat to him.
In an emergency—what animal in the world cannot be eaten?
Yaro moved a piece of bluestone from the courtyard and pressed it on the wolf's body with peace of mind.
thump!
Water splashed and wetted the corners of his sleeves.
The humanoid body... slowly sank.
With a flick of his sleeves, Yaro turned and left.
"Time to make a telescope."
Not only did the Mannheim Market not have telescopes for sale, they didn’t even have the raw materials for glass.
Fortunately, Yarrow made a lot of glass when he was doing optical experiments, and he was no stranger to the raw materials of glass.
The simplest raw material is quartz stone, and it is best to have pure milky white quartz stone.
This material is very common, not to mention that many places in Perrin Castle use this material. Even if you really can't find quartzite ore, you can pick out a lot of it by grabbing a handful of fine stones.
Yaro didn't need to do this. Since quartz stone was used in many places in Perrin Castle, it meant that there were quartz stone veins around. He had already collected a few pieces on the way back.
Simply using quartz stone as a raw material requires a high temperature of about 2,000 degrees.
Yarrow has fire lava stone, and the Fire Epee also has lava eyes that can store fire power. Two thousand degrees is not an unreachable high temperature, so there is no need to search for and make soda ash.
Take out the milky white quartz stone from the space ring, continuously heat and cool it, and then beat the palm-sized pieces of quartz stone into fine grains of sand.
A semi-enclosed kiln is made of clay, quartz sand is placed inside, and a flame is continuously released into the kiln.
The temperature inside the kiln gradually increased, and the black interior became brighter and brighter, and even made crisp cracking sounds.
Fortunately, the kiln wall is thick enough and can withstand it for a short period of time.
The kiln wall is a whole, and the internal temperature will continue to radiate out. However, the quartz sand can only withstand this high temperature completely, and then becomes brighter and softer, gradually softening and dissolving.
After all the quartz sand dissolved into a dazzling and viscous liquid, Yaro breathed a sigh of relief. He looked at the several pattern gaps on the heavy fire sword, and a trace of physical pain flashed across his face.
"It takes three molten stones to make glass. If I had known that it would take so many molten stones, I might as well have made some soda ash."
If soda ash can be found or produced, the required temperature can be lowered to about 1,500 degrees.
"Soda ash can also be used to perform saponification reactions, and can also be used in subsequent production of soap and glycerin."
However, the heat resistance, shock resistance, wear resistance, and even light transmittance of pure quartz glass are much better than ordinary glass, so it is really impossible to compare whether it is a loss compared to buying and selling.
After waiting for a while, the temperature in the kiln gradually dropped.
The bright glass solution gradually changed from liquid to viscous.
Yaro used his fire magic to release his magic hand. He first rubbed the glass solution, and after making sure it reached the desired consistency, he began to make the convex mirror of the telescope just like kneading plasticine.
Yarrow has many experiences of making ordinary glass. Except for the temperature required, the molding process of pure quartz glass is no different from that of ordinary glass.
As for the concavity and convexity of glass, it is not a difficult problem to calculate out of thin air, not to mention that there are many examples in the academy.
According to the accuracy of the academy's example, Yaro quickly produced the finished product.
