The mirror problem was finally solved by Soraya.
Referring to the mercury taken from the laboratory, she painted a dazzling coating directly behind the glass, similar to the effect of a mercury mirror, and also avoided the risk of mercury vapor poisoning.
Compared with mirrors pasted with silver flakes, the overall smeared mirror surface is more reflective. Roland simply freed up a batch of crystal glassware and made a small mirror for each witch that is easy to carry. This kind of small gift that could clearly see his appearance made all the witches extremely happy, and even the usually peaceful Scroll showed a smile, which made him have to sigh, although the witch is infertile, she is still a woman in essence.
It is a pity that this convenient daily necessities cannot be sold to the public at a low price for the time being. The price of crystal glass as the substrate is high, and the laboratory needs to consume a lot of glass to make colorless and transparent containers. Camere Strell knew how to make colorless glass, but the lab was so heavy that it couldn't have enough manpower—most of the apprentices were busy purifying two acids and soaking cotton wool, while the chief alchemist brought two or three A disciple devoted himself to overcoming the threshold of mercury fulminate. Until the industrial acid production method is researched, they will not think about making other things for the time being.
In addition to the mirrors, the way of moving the object distance has also changed from moving the stage with fingers to controlling the movement of the barrel with a knob. Roland only needs to mention a few things, and Anna can understand it. Under the black fire processing, the new fixed bracket was quickly processed, and the two sets of lens tubes with the highest magnification were selected, and the first complete optical microscopes were obtained.
Taking advantage of the sunny afternoon, Roland called all the members of the Witch League to the backyard of the castle, and the first natural biology class officially started.
…
When Lily walked into the backyard, she found that the plants were a little more lush.
The grapes on the wooden rack had turned a vivid purple-red, and she remembered that it had been less than a week since the last ripening. From time to time, lightning flew up, picking a bunch of ripe grapes and throwing them to everyone. And the big stupid bird who had just joined Border Town simply stood directly on the shelf, picked up the grapes one by one, raised his head and swallowed it.
Under the shade of greenery in the middle of the backyard, His Royal Highness the Prince was chatting with Anna, looking like a close couple, but Lily knew that they were definitely not talking about love. If you approached and listened carefully, you would definitely hear a bunch of inexplicable terms and inexplicable debates... For example, what does a small ball look like, a cat that is dead and alive, matter turns into a wave, etc. Maybe the nightingale is far away from the two of them. Keeping a distance of more than five meters is also for this reason - listening to it for a long time will definitely make people drowsy!
Wendy always stayed with Scroll, smiling and gentle at all times. Sometimes she even felt that the other party looked at her as if she were looking at a child. Lily sighed helplessly, glanced at Wendy's chest, and then looked down at her own, there was indeed a world of difference.
When can it become like that, it is not a child.
After all the witches arrived, His Royal Highness Roland placed two gray-black metal utensils on the table, which should be the microscope he claimed to be able to see the subtle world. Lily thought, maybe objects will become different when enlarged, but everything in the world is made of small balls? She could not believe this, how could a round sphere form a solid rock
His Highness asked the guards to bring a bucket of water, took out a few drops and put them under the microscope—contrary to what Lily expected, the bucket of water was neither turbid nor dirty, it was crystal clear under the light, and it seemed to have nothing. Could it be... Can you really see flowing balls under a microscope
"Something is moving in the water!" To her surprise, the sisters' exclamations came one after another, "Ah, it ran away!"
"More than one, there seem to be many more."
"My God, is this a bug? They all look alike!"
"This looks like a transparent crab..."
Lily's heart was suddenly hung up, is it not a small ball or a bug? Your Highness is indeed lying! But... it's weird to have bugs, I just saw that there's nothing in the water! When it was her turn, the little girl couldn't care less about pretending she didn't care, she couldn't wait to narrow her eyes and put her head close to the microscope.
Then she saw an incredible scene.
I saw that within the narrow aperture, many strange-shaped objects were swimming freely, some were square, with soft hair growing around their bodies, some looked like a hybrid of beetles and crabs, and some looked like grains of wheat with feet. No matter how strange the shape, most of them are transparent, as if they have no shell or skin, and can clearly see the inside of the body - of course, these worms are almost empty in their stomachs.
"Your Highness, are these really bugs?" Scroll asked.
"What you see should be some protists or single-celled algae. It is not appropriate to say that they are bugs. They should be classified as microorganisms." Wang explained.
"microorganism?"
"Yeah, they are also a kind of life, but they are much smaller. In addition to the two you see, there are even smaller bacteria and viruses. The magnification of the current microscope is not enough to observe these two. There are microorganisms, and they are also the cause of food and various diseases." The more His Royal Highness explained, the more interested he became, "These tiny beings are everywhere and in great numbers, but fortunately most of them are not resistant to high temperature, so why should the water be boiled? After drinking, the fish should be cooked and eaten, and the bath water should not be reused for this reason.”
Although it's hard to imagine that there are smaller creatures than this, Lily couldn't help but get goosebumps when she thought about how she swallowed a lot of bugs when she drank water.
And His Highness said that these inconspicuous little things are the culprits of food
If bread and meat porridge can be kept fresh, then water... should be.
Thinking of this, she couldn't help but release her magic power, covering the water droplets under the microscope.
An unexpected change has occurred.
I saw some of the "bugs" tremble, and then quickly changed their appearance. Their skins were no longer transparent, like wearing purple armor, and tentacles grew around their bodies, and began to devour the insects that remained unchanged. No... not devouring, Lily saw, they were assimilating each other at an alarming rate. The tentacles are like sharp rapiers, and after piercing the body of other microorganisms, they can turn the other party into their own appearance.
I don't know if it was an illusion, but she felt that these mutant swarms were still changing those invisible lifeforms, and soon, little purple spots appeared in the water. After a few breaths, more and more light spots gradually joined together, as if a lavender carpet had been spread over the field of vision. The tentacles are arranged one by one on the stalls, neatly like an army. As if sensing their own attention, their tentacles all lifted upwards, as if saluting.
For the first time, she saw the true face of her own abilities.
