Chapter 157 Even stealing money is not so fast! (seeking subscription)

   "Professor Lynn, what is this? A mirror?" Lydia propped her feet on a chair, leaned on the laboratory table, stared at the smooth and flawless round mirror in front of her, and asked in amazement.

There are also mirrors in the Land of Wizards, but they are all polished and smooth bronze mirrors. I heard that some master wizards will bless magic on them, but Lydia is sure that even the best bronze mirrors in the Land of Wizards cannot compare. One ten-thousandth of it!

   "Yes, I call it a glass mirror." Lynn smiled and nodded.

  Darren and other halflings also gathered around, looking at the clear image reflected in the mirror in amazement.

   "Perfect, it's so perfect... It's even clearer than the reflection on the lake." Darren couldn't help but admired, he had never seen such a beautiful mirror, it was like a work of art.

After obtaining Lynn's permission, the halflings stretched out their hands cautiously, held the round mirror in their hands, and gently touched the transparent mirror surface, as if they would tear the precious round mirror with force. The mirror is broken.

Lin En looked at the expressions of Darren and the others as if they saw a rare treasure, and it was a little funny. Originally, he thought that since the wizards had a preliminary understanding of the laws of the operation of the stars, glass, a necessary technology for observing astronomy, should have been Just click it out.

   After asking Harov, I found out that the wizards of the school of prophecy developed all kinds of long-sighted magic in order to observe the starry sky, and even upgraded the alchemy eyepiece several times, but they insisted on not researching this aspect.

   No way, magic is so easy to use that Lynn has become accustomed to using magic to solve problems. For example, making glass this time normally requires the use of a furnace, but he solved it all with a single fire magic.

  Lydia fidgeted left and right, staring happily at her own reflection in the mirror. No girl could refuse such a smooth and flawless glass mirror that could clearly reflect her face.

   "Professor, is it made of this special sand?" Lydia reluctantly handed the round mirror to the next halfling, looked at the basket of raw materials on the table, and asked curiously.

   "How is it possible, this must be the effect of magic!" Darren said with great confidence.

  How could such an exquisite glass mirror be made simply with some sand and stones.

   So it must be magic!

  Lydia ignored Darren and looked directly at Lynn, waiting for his answer.

"Yes, the main component of glass is silicon dioxide, which is found in the sand. The production process does not require any magic, as long as it is melted at high temperature and then shaped into the shape you want..." Lynn clicked Nodding, she affirmed Lydia's guess, and then briefly explained the production process of the glass mirror.

  Now that the glass mirror has been produced, Lynn is naturally not satisfied with just using it for an experiment. This novel product will inevitably set off a new trend in the wizarding land.

As for the follow-up mass production, it is impossible for him to be personally responsible, and there are not many people who are trustworthy. These halflings have at least been tested. A large amount of magic gold coins were sent to him, and nothing like filling his pockets happened.

   As for the leaked airship drawings? It was Dallak who obtained Ralph's body from Sheriff Leia, and searched the memory with psionic spells to obtain part of the information.

  He can't blame a dead man for failing to keep the secret in his head, can he?

Of course, Lynn also retains some slightly more complicated techniques, such as the production method of mercury and tin foil. He plans to teach several wizard apprentices separately, and separate the entire production process, so as to avoid the greatest degree of formula confusion. Give way.

  After Lynn explained the method of making the glass mirror, all the half-body people were a little surprised. Except for the high-temperature furnace needed to melt the quartz sand, there is almost no technical difficulty.

  The cost is also extremely low, probably only a few silver coins are needed.

   But if it is for sale, Darren believes that even if the price is 20 magic gold coins, there will be people rushing to buy it!

   With a profit of thousands of times, even if it is a money grab, it is not so fast!

  …

  Two days later, at noon, thousands of wizards were gathering in the hall of the magic seminar, discussing the next topic with great anticipation.

  They have all received the news that Lynn will be here today to reveal the last secret of the planet under their feet.

   "What method do you think Your Excellency Lynn will use this time to weigh the planet under our feet?" Raphael looked at August beside him, and said in a deep voice.

  He thought about it for two full days, pulled out a lot of hair, and didn't have any clues, it seemed like it was impossible to do.

   "Probably use the division method, just like when measuring the circumference." August's face was filled with a confident and easy-going smile.

"Now that we know the volume of the planet, we only need to select a few areas as samples, weigh them, find out how many cubic meters of soil weighs one ton, take an average, and then calculate the volume according to the volume ratio. Roughly estimate the weight of the planet under your feet!"

"Of course, these are just my humble opinions. The geology of different regions is different, and there are special situations such as mines and oceans, which need to be classified and discussed." August said very modestly, but he still revealed his own estimate. value. "The weight I calculated is about 30 trillion tons! The error should not exceed 20%!"

  Raphael and the others lamented that Augest is worthy of being a star in the magic world, and his brain is really easy to use, and he can think of such a method.

  They have all heard that after Lynn returned to Greenriel, he immediately had two piles of sand and stones brought over. Now that they think about it, they should be estimating their weight.

  Rohr also looked at August with admiration. He felt that his teacher had already glimpsed the truth. This is probably the only way!

  A few people were talking, and there was a burst of laughter from the side.

   "Mr. Koror, do you have any different opinions? Or have you found a better method of weighing?" Roll looked dissatisfiedly at the wizard next to him.

   "Sorry, I don't know what the weighing method is." Koror shook his head. He only knew that Lynn needed the sand and stones not for weighing, but to make some kind of experimental equipment.

   Then without waiting for everyone to ask questions, Koror pointed to the curtains that were suddenly drawn around, and said with a smile. "But I guess it must have something to do with the darkness!"
