well!

Whenever this happens, Martin regrets it.

I learned programming myself to prepare for becoming a special creature like a programmer.

In this world without computers, the knowledge he mastered has no use at all.

Otherwise, I will definitely take other courses.

Even those elective courses will be as serious as possible.

At the moment, I had to explore it slowly.

After making up his mind, Martin immediately took out the lens from the lens barrel, took out paper and pen to draw the imaging principle of the lens drawing.

Looking at the figures he drew, Martin frowned and thought for a while, and then made some necessary improvements.

For example, adding a concave lens in front of the first lens can improve the chromatic aberration problem, and the distance between the lenses must also be adjusted...

During supper, at the dining table, Martin met the heroic third prince.

This time he did not wear armor, but was wearing elegantly crafted, low-key and luxurious casual clothes.

The blue-gold pupils are very conspicuous, and the cold face is still very pressured.

This look of dignity naturally reminded Martin of what he looked like when he first saw him.

Because of the existence of His Highness the Third Prince, the dining table was much quieter than before. The two children Clin and Rocky were eating with their heads in silence, and the atmosphere was slightly depressing.

After a sumptuous dinner, Martin tactfully said goodbye to His Highness the Third Prince and the Earl.

It was not until he left the Earl's Manor in a carriage sent by the Earl that Martin breathed a sigh of relief.

Of course he could feel that the third prince was observing himself intentionally or unintentionally while having a meal.

Martin was a little confused.

Why is the existence of a noble person like the Third Prince interested in a small person like himself?

In addition, as far as he knows, the third prince should be here to investigate the rebellion of the Immortal Cult.

However, it has been more than half a month since the matter has passed, so why is he still staying here and not leaving?

However, this obviously had nothing to do with him, so Martin simply stopped expending his brain cells.

There are more important things waiting for him at present.

Shaking his head, Martin got out of the carriage and went straight back to his residence.

At night, he began to calm down and sort out his optical knowledge.

This is something that promised Mr. Karan. You must not be lazy, and you must organize it as carefully as possible.

However, the light field should start from that angle, which made Martin, an expert with the two swords, a little difficult.

Light is essentially an electromagnetic wave.

Light in the conventional sense refers to the part of electromagnetic waves that can be perceived by the human eye.

The relevant principle is almost the refraction and reflection laws of light.

Martin shook his head subconsciously.

He felt that Mr. Karan was definitely not satisfied with these superficial things.

I believe that the most core question for this gentleman to be uneasy is what is light?

This is very difficult to answer.

Because this is definitely a question that can easily lead to more problems, even experts in this field will spend a lot of time explaining.

If you study it downward, you will also involve physical knowledge at the micro level.

When Martin thought of this, he couldn't help but feel a little overwhelmed.

Speaking of which, although there were basic courses such as university physics in college, it was not taken seriously at that time and I never studied this in depth!

Besides, even the things I told in college may not be comprehensive.

After thinking about it, Martin could only write down everything he knew.

As for how much you can understand, it depends on Mr. Karan's understanding.

...

On Saturday, 27th, the weather is clear.

After finishing today's class, Martin, who was slightly tired, enjoyed a sumptuous dinner at the Earl's Mansion and returned home with satisfaction.

As soon as I got off the carriage, I saw a familiar figure waiting at my door.

Doriani carrying a rattan basket.

The moon was squatting on her shoulders, very well-behaved, and still looked at Martin with those very human eyes as usual.

Unfortunately, except for thinking that this guy is a little smart, Martin has not found anything unusual about it so far.

As usual, Doriani came to deliver food.

This time there are some shrimp flavored cookies.

I have to say that with the advice and encouragement of Martin, the foodie, Doriari's cooking skills have made great progress.

Not to mention the taste of these shrimp-flavored biscuits, the appearance alone has greatly improved.

In addition, she also brought the latest news.

Just as Martin was busy teaching three students at the Earl's Mansion, a case similar to Dorothy appeared again.

Two days ago, while she was divining a dead man, she saw a symbol with a golden flame again.

The mark of the fire of Modes!

However, the deceased could not see any other abnormalities on the surface, as if he had died from a sudden disease.

If it weren't for the previous incident that aroused the alertness of Shijiang's team, this incident would have been ignored as an ordinary death.

Shi Jiang had already notified the garrison, expanded the scope of abnormal cases, collected all the deceased in the past half month, and conducted relevant tests.

The temple, which received the news, attached great importance to this. After knowing that it was related to the Fire of Modes, began to pay attention to the soul of the deceased and sent special envoys with expertise in this area to identify the bodies one by one.

After strict inspection, more than ten related victims were found among the deceased.

Martin speculated that the souls of these people should have been taken away by some special extraordinary means before their death.

Martin doesn't know their names and abilities in the soul field.

But in the nightmare, he once saw the priestess take action.

Eat the biscuits in his hand, Martin said a few words of praise as usual, and the round-faced boy who had met in a nightmare appeared in his mind.

"Are you found that these dead have anything in common?"

Martin asked looking at Doriani.

"There are businessmen, poor people, and middle-class families. There is no connection at this time. Sometimes there is only one dead person in the family, and sometimes the whole family is killed...so it is suspected that it may be because of the soul."

Doriani also frowned helplessly.

soul?

What is the special thing about the victim's soul?

However, this is just a speculation, and I'm afraid there will be no answer for a while.

After seeing Doriani off, Martin drew his messy thoughts in his mind and continued to write optical textbooks.

November is coming soon and the weather is getting colder.

According to experience, Martin speculates that the current temperature should be in the early ten degrees.

However, it is said that for a long time to come, the temperature in Faralinburg will be like this, and will stabilize at this temperature for a long time and rarely continue to cool.

Because of its approach to the sea, Faralin rarely snows due to its influence from the ocean.

There are only rainy season and dry season here.

After being here for more than a month, Martin has not observed any changes in the angle of sunrise and sunset.

According to the physics knowledge on Earth, Martin guessed that this was probably because the rotation axis of this planet is nearly perpendicular to the plane of rotation...

The next morning, Martin did not go to the Earl's house to attend classes.

Because I got the news yesterday, a grand banquet was held at the manor today.

The Count also invited Martin to attend.

However, as soon as Martin found out that all the aristocrats involved were all involved, and even prominent figures in the temple, he immediately lost interest.

He is a little-known little person like him, and he has no status. Even if he has an endorsement from the earl, he can only act as a background role.

He didn't have such awareness.

Instead of wasting time in vain, it is better to use your precious time and energy to do other meaningful things.
To be continued...
