If I had known that the so-called "good idea" of Xian Ge Yayi was to let me once again bring a mountain of quartzite jade to sharpen his lenses, I would never have had the idea of using binoculars to help him improve his eyesight in the first place.

The short-sighted Elven Ranger seems to be confident in his speculation. He almost took out the last piece of his body and searched for a large number of alchemical raw materials and ingredients for refining glass. I always thought that it was not necessary for him to spend so much money to test a hypothesis, and that such a third of the material would be sufficient, but Xian Ge Yayi replied helplessly with a dejected face:

"If you can spend it all, you can spend it all, anyway, if you stay, sooner or later you will be exploited by Concubine Yin."

I really can't think of enough arguments to refute him.

After buying everything we needed, we headed to Edgewell's lab and began the tedious work again.

The so-called "breakdown" and "boring" are just for me. You know, in order to make a "telescope", I used to study repeatedly in this small and dilapidated laboratory, and almost the entire mountain was smoothed by myself, and the hardships and tedium of this time could only be understood by the omnipresent and omniscient supreme god Darimos. Now that I am facing this magic crucible that is like a large coffin again, it is difficult for me not to give birth to a strong psychological shadow, only to feel that the road ahead is endless, and I want to die of despair, and I just want to fill myself and melt it down with the raw materials for refining glass.

But the heartless elven ranger did not understand my distress at this time, and his first visit to the alchemist's house made him curious about everything around him. He ran to Mr. Edgwell, and put almost his whole face on my teacher's nose, and then he got a vague look of his face, and then immediately spat on his face in astonishment:

"Poof...... Einstein? He's the one who teaches alchemy?! ”

It was evident that my teacher had mistaken my teacher for another strange old man with a clear face, unkempt hair, and a nervous eye, and I have to admit that if an old man had all of these traits, the difference between them was not very great.

Lying on the table, he watched with great interest as Edgwell did his explosive experiments, unaware that danger had come, and was still asking all sorts of strange questions at him:

"Hey, Jeff, what's in there?" He grabbed a small bottle on the table filled with small black granular objects, pinched one out and played with it, and asked me a question.

"Rat droppings." As soon as I turned around, I saw this overly curious elven ranger pinching my teacher's biocatalyst and licking it on his tongue.

"Ahh............h What is this for? ”

"It's a small rotary rotor solids grinder, which grinds large pieces of hard objects into powder, which we usually call grinding discs." I didn't stop working on my hands, and I just glanced back.

"And what is this?" String Ge Yayi grabbed the gadget on the table again and said.

I was annoyed by his frequent and boring questions, but patiently explained to him: "Mr. Edgwell calls this thing a molecular polymer of calcium carbonate and silica, but in general we usually call it 'stone'......" I shook my head helplessly, and said to him angrily, "...... Although your eyesight is not very good, you should always recognize this kind of thing, right? "I really can't figure out where his curiosity came from.

Hearing my impatient words, the strings finally fell silent. He wandered around the laboratory, occasionally looking at a tool with great interest, as if he could find something special in it that I couldn't see. However, his silence did not last long, and after a while, he finally couldn't help but ask:

"Jeff, I promise that's the last question. I really can't figure out why your teacher's face looks so dark? ”

"It's because ...... Ah, be careful! ”

"Boom!" Before I could finish my sentence, a habitual explosion occurred on Mr. Edgewell's test table. A cloud of fire mixed with billowing smoke erupted, enveloping the strings that were coming up to observe carefully.

When the smoke cleared, Mr. Edgwell looked left and right happily, and then with his signature honest smile, he said to himself or to my elven ranger friend, "Don't worry, it's just a small accident." ”

“…… Now you know why his face is always so dark, right? ”

Xian Ge Yayi's face was full of oil, he took a deep breath, spewed out a black smoke in embarrassment, and nodded blankly.

This little accident didn't slow me down. For me, who had a nervous breakdown in front of a magic furnace in order to build a telescope, and was about to reach the seventh level of alchemy, the production and purification of glass was almost a tedious but simple manual labor, and there was no great technical difficulty. It didn't take long for the ore and other materials that String Ge Yayi had bought to become small pieces of "pure glass".

The real headache is the grinding of the lenses. What is needed is two concave lenses that are thin in the middle and thick on all sides. Unlike looking at the drawings to build a telescope, I didn't know exactly what I was going to do to polish the lenses to be successful, and all the judging criteria were based on the very subjective personal judgment of my elf friends. Whenever I polish a finished lens, he squints the other eye before taking it to one eye and looks out through the lens. His blank eyes were like a pool of stagnant water, unable to gather the slightest bit of agile brilliance. Then he would shake his head in disappointment and tell me to thinner the lens a little more – until it was broken and scrapped in my constant processing.

I don't know if it is the improvement of the alchemy level that has allowed me to grow my mastery of matter, or the operation of grinding lenses for a long time has made me more comfortable with this work, in short, fortunately, I found that the success rate of grinding lenses has improved significantly, and I will no longer clumsily smash the whole piece of glass on the grinding machine and directly cut it into slag, but can adjust the grinding angle lightly, and find a delicate feel in the slight touch. Let the glass piece in his hand produce subtle changes at all.

It was a magical feeling, and although the glass had not changed much, only slightly thinner in the subtleties, and no one would have seen the change even if it had been brought to me, the sensation of my fingers was becoming more and more precise, and even the finest changes in the lenses could not hide its more sensitive sense of touch.

The lenses I tried to make were getting thicker and thicker, even a few points thicker than my shield, and it seemed that they were still a little too thin. I don't know exactly how thick a concave lens he needs, but I think it would be a bit of a haphazard if he used it as just a tool to improve his eyesight—if he could have made the lens bigger and completely covered his little face, I think the glass mask might have been better protective than a sturdy steel helmet.

When I was polishing telescope lenses before, I noticed some wonderful phenomena: looking through a convex lens makes the object look bigger, while looking through a concave lens makes the object smaller. But now it seems that this little principle has no effect on these thickened lenses in my hands. Through these lenses, which are as thick as a wall, I can only see a dizzying chaotic world, with large blurred patches of color circulating with the movement of light and shadow, stirring into a terrible world of twisted and turbidity, which makes people's heads ache. I think it's a great tool for masochism, and if you put it on your eyes, you might faint and die by yourself even if you don't do anything, and now I'm told that relying on it can "improve your eyesight"?! All I can say is that the world is so big that it's possible to meet any kind of strange person.

After hundreds of failed trials, I honestly have completely lost faith in our attempt, and the reason why I continue is because my ranger friend seems to be very fascinated and interested in this matter, and I don't want to spoil his interest; Second, I found that my alchemy skills were slowly growing as I continued to polish my lenses—it wasn't me who spent money, I thought it was all free—and I felt sorry for taking advantage of the strings, but I couldn't help but feel sorry for such a good thing that didn't cost money.

(Depressed, why did everyone guess that I was going to make glasses??? ）
