Wizard of science

Looking at the corpses of many little squirrels, Li He narrowed his eyes.

"All died? How did the two little squirrels survive before? Could it be that the previous judgment was not correct. The high-temperature treatment of biological inactivation in the initial stage and the pH balance in the final stage did not reduce biological toxicity? Where did the problem arise? What? Why didn't you take it into consideration?" Li He frowned and thought.

He couldn't help but sigh softly in his heart.

Although he was a little reluctant, he had to admit that due to the lack of systematic understanding of mysterious knowledge, when conducting experiments using scientific methods, he could not quickly find the breakthrough direction, and he could not quickly locate problems when they occurred.

Because of the lack of mysterious knowledge theory, in many studies, he could not directly make breakthroughs from theory. Instead, he relied on exhaustive methods to obtain results from the application field, and then worked backward to clarify the theory.

As a result, the workload is large and the difficulty is relatively high.

And if you want to solve it, you must learn a lot of mysterious knowledge.

And there are not many ways for him to learn mysterious knowledge now, only...

"call--"

Li He breathed out gently, walked towards the iron shelf in the corner, took down the "Book of Destiny" from it, walked towards the vibrator, and prepared to read.

But in front of the concussion machine, he shook his head and did not put the "Book of Destiny" on it.

Because he felt his physical condition and found that it was not ideal.

Although the body is tired, it can still hold up. But mentally, after a series of thoughts and experiments, I was very tired.

Reading "The Book of Destiny" is exactly a test of spiritual strength.

Normally, I am very energetic and reluctant, but in this state, I will definitely gain very little, so it is better not to read.

Li He frowned deeply, his thoughts slightly divergent.

Speaking of which, although the "Book of Destiny" can provide a lot of knowledge, because it has never been able to find the correct way to open it, it can only be forcibly cracked by relying on the vibration machine. The total amount of knowledge gained in a period of time is not much.

After all, the "Book of Destiny" only displays the text for a short period of time and will disappear soon. You can't remember much by just relying on your own brain.

Maybe we can let Weier, Faile and Alex come together to help with reading and memory? Li He had this idea in his mind and immediately rejected it.

The memories of the two little girls, Wei'er and Feier, were only average, and Alex couldn't even remember the past, so calling them over to help wouldn't be of much use at all. Moreover, relying on brain memory is bound to be unstable and may make mistakes. This is obviously not a solution to the problem.

The best way is to use props.

It is best to use a prop that can quickly record the text content in the book, and then slowly read, organize, and study it.

This prop cannot be too big and the production cost cannot be too high. Its main function is to quickly record text, and the text must be clear and error-free.

If possible, it is best to form an image directly, so that some unknown words and imperceptible details can be directly recorded.

"Speaking of it..." Li He raised his eyebrows and whispered, "Speaking of it... what I really need is a camera."

Yes, what he needs is actually a camera that can quickly take pictures and record the contents of the "Book of Destiny", and then organize, read and analyze it afterwards.

In this way, during the time when the "Book of Destiny" is activated, a large amount of mysterious knowledge can be quickly recorded, and it can also be guaranteed that there will be no errors.

In theory, making a camera is not very difficult.

Li Hyuk started to think.

Advanced cameras such as digital cameras are not considered for the time being and are not necessary. All you need is a simple camera that can achieve the most basic functions.

He is not a practitioner in the camera manufacturing industry and does not know the specific manufacturing details. However, he understands the principle of the camera and it is actually very simple.

It's just light imaging.

As we all know, light travels in straight lines. Let light enter the inside of the camera to form an image, and then find a way to record the image, which is the camera.

The main body of the camera is the camera obscura, which is where the light enters, and the key is the photosensitive material, which is what records the image.

The rest, such as lenses, apertures and a series of accessories, are all details.

If you want to make a camera, for now, the key is to make photosensitive materials, which is a bit troublesome.

After all, photosensitive materials need to react to light, form images clearly, and then be fixed without changing.

This involves several chemical reactions…

"first of all……"

Li He thought about it, put away the "Book of Destiny", walked to the middle test table, sat down, took out a piece of papyrus and started writing.

"After that……"

"Then..."

"Swish, swish, swish..." After a while, Li He filled up several pieces of paper, which contained specific principles of chemical reactions and the materials needed to realize these chemical reactions.

After finishing writing, Li He read it over, revised a few small details, exhaled lightly, and nodded with satisfaction at the papyrus full of words: "It's almost done... Next, we just need to find a way to solve the material... Then …”

…

In the blink of an eye, a few days later.

night.

The small town of Dognag.

Deep in the brightly lit Earl Dogg's mansion, the thin Earl Dogg sat on the black walnut wood chair as before, but compared to before, he had a bit more cold aura.

There was a creak of the door, and a servant walked in cautiously.

Earl Dogger raised his head and looked at the servant with his bloodshot and cloudy eyes.

The servant couldn't help but tremble.

Earl Dogger ignored him and said hoarsely and coldly: "Say."

"Yes, Lord Earl. According to the people who came back, currently... currently..."

"What's going on?!"

"Currently, we have searched the entire territory, but... we still haven't found the Marquise Isa and her entourage.

In addition... there is no trace of Lord Mons or the soldiers around him. It seems that they all encountered an accident together and disappeared..."

The servant's voice became lower and lower, and his head lowered as well. He knew very well that Earl Dogger was in an extremely bad mood, and was afraid of irritating him in any way.

After hearing what the servant said, Earl Dog couldn't help but grab the armrests of the wooden chair and snorted coldly: "An accident has happened? With so many of them, what accident can happen to them?"

"Maybe...met a wizard?" the servant whispered, glanced at Earl Dog, and then quickly lowered his head again.

"Wizard?" Earl Dogg opened his eyes slightly, "What wizard? This is the Kingdom of Fornalanza, not a place where wizards live. What kind of wizard can be here?! Don't blame everything on the wizard!"

"Lord Earl, it is true that there are no wizards in our kingdom. But... what if they are from outside? A few days ago, a wizard came to our territory. Maybe there are other wizards..."

Before the servant finished speaking, Earl Dog's eyes suddenly became sharp. He quickly stood up from the wooden chair with his rickety body, stared at the servant, and asked: "Who told you that there is a wizard in our territory?!"

"this……"
