It seems that because there are no more goals in a short period of time, the pace of life of Boom and the five people is extremely slow. This is the fourth day that everyone came to Crystal Mechanical Castle. After lunch, Rikka took Perseus and Ha
Star goes out for a walk, and Boom also plans to go for a walk with Christine.
"Crystal Castle's name as the 'Wombat's Butt' is really apt. I guess even you, as a peak powerhouse, will find it difficult when it's on guard."
While looking at the various heavy siege weapons in the distance, Boom looked at Christine with a smile. When he thought about it, even if the Grand Mage took action himself, it would probably take a lot of effort to easily capture the Crystal Weapon Castle.
.
"If we are fighting in conjunction with the legion, the Crystal Weapon Fortress can indeed be said to be a tough nut to crack. But now I am just a traveler, and those heavy siege weapons, no matter how powerful they are, still need living people to control them."<
/p>
"It's just like you. Even though you are a unique space magician, you still have to be on tenterhooks all day long. On the one hand, you are forced to practice hard due to the strength of Rikka, and on the other hand, you have to deal with people you don't like." p>
Christine raised her eyebrows when she heard this, then smiled and replied softly. What she said was impeccable. It not only pointed out the fatal flaw of those heavy siege weapons, but also pointed out that they still need to be controlled by living people, and as long as they kill
If you kill the person who controls it, no matter how powerful the weapon is, it will be nothing more than a pile of scrap metal.
At the same time, Christine did not forget to retaliate to Boom, reminding him that even though he is a magician now, there is still a long way between him and the peak power. But these words are also true, so Boom
Apart from being depressed, I have no words to refute.
The two chatted about anecdotes while wandering around the Crystal Mechanism Castle. Although the Crystal Mechanism Castle is a place where heavy siege weapons are manufactured, shops selling clocks and watches can also be found everywhere. Boom curiously looked at the strange things he had never seen before.
Although technological products are amazing, I have no intention of buying them.
Christine kept smiling all the time, because in her eyes, although the technological products of the goblins were special, most of them were dispensable things. However, when she passed a shop, she stopped.
, there was a trace of surprise in his eyes, and then he walked in.
"Boss, what is this? Is it a decoration?" Christine gracefully raised her hand and pointed at the wooden frame in front of her. To be precise, it was a drop-shaped glass container placed on it.
I saw that there was some kind of transparent solution sealed inside, and some snowflake-like crystals were floating in the solution, seemingly never melting.
"You have really good taste. This thing is called 'Storm Bottle', and it is a technological product recently developed by the goblins. If you like it, you might as well buy one for your collection. The price is negotiable."
When the shop owner saw Christine's elegant temperament, he regarded her as a human noble. As for Boom, who was traveling with her, he could only be reduced to a servant.
Christine smiled and nodded slightly, but did not directly ask for the price, but waited for more introductions from the shop owner. The shop owner once again confirmed that Christine must be a human noble, otherwise she would not have such a temperament.<
/p>
"Storm Bottle", the latest technological product of the Goblins, is about the size of an adult's palm and shaped like a drop of water. If someone comes into contact with it for the first time, they will definitely regard it as some kind of unique decoration like Christine did. But if you listen to it,
After the shop owner’s introduction, he would probably show an incredulous expression like Boom.
"Storm Bottle" is a weather forecasting tool newly developed by the goblins, and it is also the world's first weather forecasting tool. The outside is made of sealed glass, and the inside is mixed with several special solutions. These special solutions will change depending on the outside temperature.
The crystallization of different forms shows up due to the changes, thereby predicting the weather changes in the future period.
As for the special solution in this drop-shaped glass sealed bottle, it is the finished product after decades of research by the goblins. It is a mixed solution of various substances. The known substances include distilled water, ethanol, potassium nitrate, ammonium chloride, and
Camphor. As for the last solution, it is a secret of the goblins, and there is absolutely no way that the world will know it.
But what is unbelievable is that the last solution was not made by a goblin researcher, but an unintentional move by an airship blade repair craftsman.
It was a routine airship array performance. The blade repairman had nothing to do, so he ate in the shadows and drank ale. However, although he had long been accustomed to the deafening sound of the airship blades,
There is a roaring sound, but I can’t stand the cold wind that rushes in from outside from time to time.
However, he was just a repairman who relied on his strength to make a living, so there was nothing he could do except curse a few words. After three rounds of wine and five tastes of food, I don’t know what he was thinking, but he actually started to perform "magic" in a serious way.
Experiment".
There is still half a bottle of healing potion, a cheap perfume that he plans to give to his girlfriend, a potion that is rumored to make you smart after one sip, and the remaining ale that he drank. The goblin craftsman put on a decent posture,
While randomly mixing everything together.
After struggling for more than half an hour, he stopped this "magic experiment" without any surprise, and then "enjoyed" the slightest bit of cold wind again.
However, just when he was about to pack away the debris that was enough to make him lose his job, his expression suddenly changed and he hurriedly brought the wine glass to his eyes. The solution in the wine glass became clear and transparent at some point, and as the airship
The rotation of the blades and the slow cold wind passing by caused pieces of snowflake-like crystals to grow in the solution at a speed visible to the naked eye.
The airship repairman was amazed when he saw this, but he didn't pay much attention to it. He didn't believe that he could really tinker with anything powerful, but he still expected that the solution in the glass of wine could be exchanged for a big meal of meat and fish.
Good luck.
However, three days later, ten thousand gold coins were placed in front of the repairman. The repairman said that as long as he kept his mouth shut and did not reveal the formula of the solution, he could leave with ten thousand gold coins.
The repairman nodded repeatedly when he heard this. This does not mean how honest he is, but that he is afraid of the other party's aristocratic status in Alchemy City, and he does not understand what is in his wine glass at all.
But he knew that he was really lucky this time. Ten thousand gold coins were a huge amount of wealth that he had never been able to earn in ten lifetimes before. As long as he didn't commit suicide, he could live a comfortable life.
, not a problem at all.
Time moved forward fifteen years again. After spending a lot of time and gold coins, the goblin noble finally analyzed the cup of solution thoroughly. And the result was naturally what Boom and Christine saw in front of them.
"Storm bottle".
As for the change in the wine glass, it has been cracked. It is mainly due to the solubility of camphor in the solution in ethanol changing with temperature. Potassium nitrate, ammonium chloride and water are used to control the high-speed growth of crystals.
Continuous nucleation.
When the temperature changes, camphor crystals precipitate, and the speed of temperature change will affect the growth size and structure of the crystals. Together, these factors will resemble the snowflake-shaped crystals in the wine glass.
After three years of observation and extreme testing, the method of using the "Storm Bottle" has become almost perfect. If the liquid is clear and clean, it means the weather will be fine; if the liquid is turbid and hazy, accompanied by sedimentation and flocculation.
If there are suspended sediments and turbid liquids at the same time, it means that bad weather is coming. If there are sediments suspended in the liquid on a sunny winter day, it means it is going to snow; if on days with high temperatures or snowy winters, there are large pieces of sediment in the solution, it means it will be cloudy;
If crystals appear at the bottom of the cup, it means that the weather will change suddenly; if there are spiral patterns at the top, it means that a hurricane is about to hit.
"One hundred gold coins, this is the lowest price. If you buy a cheaper 'Storm Bottle' elsewhere, I can return it tenfold."
The shop owner rubbed his hands and quoted the cost price. There was no other reason. Although the "Storm Bottle" was good, it was just a tool for predicting the weather. Except for those nobles who had money and couldn't spend it, it was not a good thing.
What cost-effective product?
Christine glanced at Boom, who smiled bitterly and threw a money bag to the shop owner, trying hard to play the role of "servant". It was night, everyone sat around the dining table, looking at the "Storm Bottle" while
