I am the cook, but I am Li Er's son-in-law

The young man with the mole took a deep breath, boldly took a step forward, but quickly took half a step back.

It's no big deal to talk to Mr. Zhengyang, they all know Mr. Zhengyang is an excellent talker.

But... questioning Lord Zhengyang and talking to Lord Zhengyang are two completely different things, especially to question Lord Zhengyang based on one's own identity and knowledge.

Is it for my own dog's life, or for my own face.

I thought about it.

He felt... If he lost face, it would be better not to lose his life.

Anyway, it is impossible for Mr. Zhengyang to really take his own life.

The young man with the mole took several deep breaths before he bravely stepped forward, respectfully bowed to Yin Xuan who had just come out of the kitchen, and greeted: "Mr. Zhengyang, how are you?"

Yin Xuan didn't even open his eyes, he was rolling with one hand, and waved with the other: "If there's anything, just say it."

The young man with the mole spoke with a trembling voice: "The student wants to know why the student's article was not published in the magazine."

Yin Xuan didn't speak, just waved his hand.

Liu Jingxian understood what Yin Xuan meant, and was about to come over and persuade this person to leave.

It is impossible for Yin Xuan to answer. In each issue of the magazine, there are at least hundreds of unselected articles. There is only one reason for not being published, and that is insufficient level.

If it cannot be published in time due to layout problems, Yin Xuan will also send someone to notify - of course, this situation has not yet occurred.

Every time, a few little girls are needed to fill the page and support the scene.

If someone came over every time to ask why he was rejected, then Yin Xuan's restaurant wouldn't need to be opened, and a pot of tea and a stool would be given to them every day to clear up their doubts.

This problem cannot be used to.

Besides... The things they figured out by themselves must be more stable than the knowledge they got through their own guidance.

Yin Xuan is not afraid of slowness, but of weak foundation.

Seeing Liu Jing coming over first, the young man with the mole became more panicked and his voice trembled even more: "Mr. Zhengyang, the article written by the student is from the speech magnifying glass, and he also handed in a real object. The student pays for the article... ..."

Before he finished speaking, Yin Xuan opened his eyes and waved his hands, a little surprised: "You actually wrote that article?"

Liu Jingxian stopped walking.

The young man with a mole nodded and replied, "It's written by a student."

Seeing that Yin Xuan's reaction to this article was somewhat unusual, his courage gradually grew: "Students think...this thing is of great benefit whether it is for military or civilian use, why..."

Yin Xuan waved his hand again and interrupted him: "The magnifying glass is indeed a good thing."

"But did you make this thing?"

The young man with the mole was taken aback for a moment, opened his mouth, but couldn't speak.He did not make this thing, but by chance, he met a miniature carver. Among the utensils he used, he said that the most important thing was a piece of natural crystal.

Wearing this piece of natural crystal in front of his eyes, he could instantly turn something the size of a walnut into an apple-like shape. With the help of this strange thing, he became a very skilled miniature carver in Chang'an City.

The young man with a mole had the cheek to beg for this thing and studied it for a while.

Accidentally, he discovered that the glass cup he bought seemed to have the same effect, which made him open his mind and figured out something like a magnifying glass.

Overjoyed, he wrote that academic paper and uttered wild words, saying that his article would definitely be published in a magazine.

Of course, it turned out... not so pretty.

"The magnifying glass has been used for a long time." Yin Xuan shook his head, "I took out the glass. Do you think I don't know about the magnifying glass..."

"Will I hand over such a good thing to the military account?"

The young man with the mole became even more silent.

I was full of joy and thought that the good thing I had figured out, but it turned out to have been invented long ago?It's like a whimsical idea I had when I was a child, thinking that I would win a Nobel Prize if I figured it out, but it turned out that... this is already an obsolete technology.

"It's a good thing that you can figure out this phenomenon." Yin Xuan continued to comment, his voice amplified a lot, "I also know your purpose."

"What I said before is still valid."

"But I hope that you all don't be so impetuous. What I want you to take out is not just one thing, but... After you take out this thing, you can still know why."

After speaking, Yin Xuan paused for a moment, took a breath, took a sip of tea, and then said to the young man with the mole in front of him: "Now I will give you a chance."

"If you can tell why the convex surface of the glass can magnify the object in front of you, then you can enter my research institute."

Why……

The eyes of the young man with the mole were a little confused, but he didn't know why.

"Is it... because of the characteristics of things like glass?" But the opportunity to enter the research institute to make a fortune was right in front of him, and he couldn't give up easily. After thinking about it for a while, he tentatively opened his mouth and gave an answer.

Yin Xuan sighed.

The answer couldn't be wrong, but it wasn't the answer he wanted to hear.

What he wants to hear more is "phenomena produced by the refraction of light", and what he wants to hear is the most basic knowledge of optics in junior high school textbooks.

Optics is a branch of physics with little presence.

But it's really, really important.

It involves various industries, such as printing, medicine, and even mobile phones and tablets, all of which are inseparable from optics.

Seeing Yin Xuan sighing, and the young man with moles turning ashen, he knew that his answer was wrong, and his last struggle failed.

Without Yin Xuan waving his hand, he retreated by himself, and sat blankly in his position, like a piece of clay sculpture.

He is lost.

Yin Xuan's mood was very calm, he was mentally prepared for this, and continued to roll and roll with his eyes closed, recuperating.

The eavesdropping scholars became excited, they could tell that Yin Xuan still attached great importance to the magnifying glass.

This...doesn't point out the next research direction for them?
If you can figure out why a magnifying glass can magnify objects, it must be an academic paper that can be published in a journal.

Who would let go of such a good opportunity.

Except for those who are very confident in their research projects, everyone else has secretly made up their minds to change their research direction and find out what is going on with this magnifying glass.

All of a sudden... I looked like Li Shimin who was so eager when he saw Gun Gun.

There is a lot of business in Linlang Pavilion. They used to order special glass mirrors. If they are a little handy, they just polished them by themselves.
