The mirror problem was eventually solved by Sorrowa.

Referring to the mercury she had taken from the laboratory, she painted a clear coating behind the glass, similar to the effect of mercury mirrors, and avoided the risk of mercury vapor poisoning.

Compared with pasting the mirror with the silver film, the overall smeared mirror is better, Roland simply frees up a batch of crystal glassware, and makes a small mirror for each witch to carry.This kind of small gift that can clearly see their appearance makes the witches happy, and even the usual peace of mind book has a smile, so that he has to feel that although the witch can not bear children, the essence is still a woman.

Unfortunately, this convenient daily necessities can not be sold to the public at a low price for the time being, the price of crystal glass as a substrate is high, and the laboratory also needs to consume a lot of glass to make colorless transparent containers.Kemo Steyer knew how to make colorless glass, but the lab was so heavy that it was empty—most of the apprentices were busy purging the two acids and soaking the tampon, while the chief alchemist took two or three of his disciples to attack the mercury mark.Until the industrial acid method was studied, they did not want to make anything else for the time being.

In addition to the mirror, the distance of the movement of the distance is also changed from the finger dialing stage into a knob control tube body movement, these changes Roland only need to mention two sentences, Anna can understand the heart.Under the black fire processing, the new fixed bracket was quickly processed, and two of the most magnification mirror cylinders were selected, and the first fully body optical microscopes were selected.

In the afternoon, when the sun was shining, Roland summoned all the members of the Witch Alliance to the backyard of the castle, and the first natural biology class officially began.

...

When Lily walked into the backyard, she found that the plants here were more luxuriant.

The grapes on the wooden frame had turned bright purple, and she remembered less than a week since the last ripening.The lightning flew from time to time and plucked a string of ripe grapes and threw it all over.And the big stupid bird that was newly added to the border town, simply stood directly on the shelf, plowed the grapes in one mouth, and swallowed it in the stomach.

In the shade of the middle of the backyard, His Royal Highness the Prince was chatting with Anna, looking like an intimate couple, but Lily knew they were definitely not talking.If you come closer to listening, you will definitely hear a bunch of inexplicable nouns and mindless debates...such as what the small ball looks like, dead and alive cats, matter becomes wave and so on, probably the nightingale from two people to maintain a distance of more than five meters is also the reason - listening for a long time will definitely make people sleepy ah!

Wendy was always with the book, always with a smile and a gentle look.Sometimes she even felt that the other person looked at herself as if they were looking at a child.Lily sighed helplessly, glanced at Wendy's chest, and looked down at herself, there was indeed a world of difference.

When can you become that, it is not a child.

When all the witches arrived, His Highness Roland put two gray-black metal utensils on the table, which should be the microscope he claimed to see the subtle world.Lilly thought that perhaps the object will become different when enlarged, but everything in the world is made of small balls.It was hard for her to believe that a round sphere could form a solid rock?

His Highness asked the bodyguard to bring a bucket of water and remove a few drops below the microscope—as unlike Lily had expected, the bucket was neither turbid nor dirty, and it seemed to be nothing in the light.Can you really see the flowing ball under the microscope?

“Something’s moving in the water!”To her surprise, the sisters exclaimed for a while, “Ah, it ran away!”

"More than one, it seems like a lot."

“Oh my God, is this a bug?”They are not the same!”

“It looks like a transparent crab.”

Lily's heart was suddenly hung, not the little ball was a bug?Your Highness is lying!But... it is strange to have bugs, just looking at the water clearly nothing!When it was her turn, the little girl could no longer pretend to be unconcerned, and could not wait to narrow her eyes and close her head to the microscope.

Then she saw an incredible scene.

In the small aperture, many strange objects are swimming freely, some square, with soft hair around, some like a mixture of beetles and crabs, and some similar to the wheat grains with long feet.No matter how strange the shape, they are mostly transparent, as if there is no shell or skin, to see the inside of the body clearly - of course, these worms are almost empty in their stomachs.

“Are these really insects?”The book asks.

“What you’re seeing are some protozoa or single-celled algae, and it’s not appropriate to say that bugs are, they should be classified as micro-organisms.”The prince explained.

“The micro-organisms?”

“Yes, they are also independent beings, but they are much smaller, and in addition to the two you see, there are smaller bacteria and viruses.Magnifications in the current microscope are not sufficient to observe these two micro-organisms, which are also the cause of food spoilage and disease.”The more Hen Roland explained, "The more interesting these small lives are everywhere, the number is numerous, and most of them are not resistant to high temperatures, so why the water should be boiled and eaten, and the bath water should not be reused, this is why it is for this reason."

Although it was hard to imagine that there was a smaller creature than this, Lily could not help but get a goosebump from a lot of worms when she drank water.

And your Highness says that these inconspicuous little things are the culprit of food corruption.

If bread and porridge can be kept fresh, then water... should be too.

Thinking of this, she couldn’t help but release the magic and cover the droplets under the microscope.

Unexpected changes have taken place.

I saw some of the "worms" trembled, and then quickly changed their appearance, and their skins were no longer transparent, like purple armor, and they grew a tentacle around them, and began to devour the insects that had not changed around them.Not . . . not devoured, Lily saw, and they were assimilating each other at an alarming rate.The tentacles are like sharp thin swords, and when they enter other microorganisms, they can turn each other into their own appearance.

Not knowing if it was an illusion, she felt that these mutant swarms were still changing those invisible beings, and soon a little purple light appeared in the water.After counting, more and more light spots gradually become one, as if they were covered with a lavender carpet in the field of view.The tentacles were arranged on the ground, neatly as an army.As if they felt their own attention, their tentacles were all raised up, as if they were paying tribute.

For the first time, she saw the true face of her abilities.(Unfinished.
