Chapter 42 Type I Wet Plate Camera

Fleur agreed to the deal, Li Hyuk was not polite, stepped closer, took out a syringe, and quickly drew a tube full of blood.

After the extraction was completed, the blood was collected, and Fleur began to eat.But she didn't eat all the steak, but distributed it to the others, and ate it together.

Regarding this, Li He didn't say anything.

Soon, the group finished eating, and then it was time to take the anesthetic.

Li He stretched out his hand, and three small test tubes of medicine appeared in his palm.

A group of people stepped forward one by one, took the medicine, and swallowed it.

Not long after, a group of people fell to the ground one after another.

Li Hyuk glanced at the lying down people, then retracted his gaze, opened the window of the room, and looked out to the street.

It can be seen that the streets of the town after nightfall are not lively, only scattered people are walking around, either drunk traders, hunters, farmers, or pedestrians in a hurry.

The only thing that was special was a person walking from the end of the street, wearing a tuxedo, with a bit of extravagance, making the rest of the people unconsciously stay away, for fear of contradicting this noble lord, it was the devil Alenx.

At this time, the devil Alenx carried a heavy box in each hand and walked towards the hotel.Seeing Li Hyuk looking out the window, he accelerated his steps, entered the hotel after a while, and entered the room.

"Boom!"

Putting the two heavy boxes on the floor, Alenkes looked up at Li He: "Master, everything is done."

"Have you collected all the remaining materials on the list?"

"Yes, I collected them all."

"Very well, it seems that tonight is going to be busy. Then don't waste time, let's go, take the materials, bring the six on the ground, and enter the castle with me."

"Yes."

For a moment, the air in the room fluctuated, and everyone disappeared.

……

Li He entered the Blackstone Castle without any delay, and went straight to the No. [-] laboratory of the main castle to get busy.

Part of the busy content is processing the materials collected by Alenkes, and the other part is preparing for the next "big event".

hours later.

In the No. [-] laboratory of the main castle, in a small room on the first floor that was cleaned up not long ago, Li He closed all the doors and windows, and turned on the only light source—a lamp covered with a crimson glass shade.

The crimson light instantly filled the entire room, and everything in the room seemed to be covered with a layer of red tulle.

Li Hyuk looked around, walked towards a shelf in the corner, took off the glass plate on which the photosensitive material had been applied, and put it into the silver nitrate water bath next to it.

The silver nitrate solution submerged the glass plate. Li He silently counted the time. After about 5 minutes, he took out the glass plate soaked in the silver nitrate solution and put it into a device similar to a metal iron box. Li He temporarily named it Type I wet plate camera.

After putting the glass plate into the camera, Li Hyuk took out the "Book of Destiny" from another iron stand and put it on the adjacent vibrating machine.

"Om-"

The vibrator oscillated rapidly, and words began to appear in the "Book of Destiny", and it stabilized after a while.

Li He seized the time, unfolded the "Book of Destiny", placed it on a wooden table, adjusted the lighting, picked up the camera that had just been put down, and started shooting.

"Clap!"

An auxiliary switch on the camera clicked, and the exposure was completed. Li He quickly took out the glass plate, put in a new glass plate, turned the "Book of Destiny" to a new page, and started another shooting.

"Clap!"

Another shot.

"Clap!"

Shoot again.

"pat pat pat pat..."

Continuous shooting.

After a while, all the content on the "Book of Destiny" disappeared, and Li Hyuk stopped filming.

But they didn't stop busy, collecting all the used glass plates at the fastest speed, putting them into the developing pool next to them, and immersing them in the developing solution.

The photosensitive material smeared on the glass plate begins to appear images under the action of the developer after being stimulated by exposure.

Under the crimson light, Li Hyuk opened his eyes wide and carefully observed the extent to which the development was affected. Once the expected effect was achieved, he quickly took it out, put it into the cleaning pool next to it, and washed away the excess developer with flowing water to prevent excessive development from affecting the final product. film effect.

After completing this step, Li Hyuk still didn't stop, and immediately put the glass plate into the fixing pool to fix the image and prevent future changes.

After fixing, take out the glass plate, put it into the second cleaning tank, and wash off the excess fixing solution with flowing water.

This cleaning took a long time and ended after more than ten minutes. Then put the glass plates on the alcohol lamp one by one and dry them carefully.

Finally, the paint is applied and the perfect image is finally obtained.

Li Hyuk let out a long breath, looked at the final product, and nodded with satisfaction.

……

Afterwards, Li Hyuk left the "photography darkroom" and returned to the main research room, put the wet-plate photographed film on the test table, and began to seriously transcribe the content.

It has to be said that technology is the primary productive force.

Only this time, the content captured by the Type I wet-plate camera is more than ten times the content that the brain has worked hard to memorize before.

"Swish..."

Holding a quill pen, Li Hyuk quickly wrote on the papyrus paper.

While transcribing, organizing and analyzing.

"Spell burning waterfall? Well, it looks very powerful, but I can't use it for the time being, let's use it as a reserve of knowledge... rustle..."

"Giant-eyed flower? It can cure negative energy erosion and permanently increase the vitality of the human body... This is good, but it needs to be watered with blood every day to grow. It seems that the breeding conditions are a bit harsh. I don't know if human blood is necessary... Rustle... "

"Crow to death? Can perceive the death event that is about to happen. Once it appears, it means unknown... If you can predict the future, what is the principle? This is a chance, you can study whether it is true... rustle..."

"..."

Li Hyuk copied and analyzed the contents of the "photo" one by one.

Suddenly, his eyes focused on a long paragraph of text in "Photo".

"Mixed race improvement test record (continued)?!"

"There is a follow-up to the experiment recorded before? Can the random knowledge this time be continuous with the previous knowledge?"

"It seems that as long as there is enough content recorded each time, it can be guaranteed that the knowledge is no longer fragmented, but can be pieced together to form a complete book and a relatively complete knowledge framework."

"Then let's see what information the so-called improved experiment (continued) has given me this time."

Li He whispered, carefully copied and read.

As the transcription and reading progressed, Li He's expression became solemn, his brows were sometimes furrowed and sometimes stretched.

After a long while, after transcribing and reading, Li He looked at the content on the papyrus, muttered to himself with flickering eyes: "It's really a bold experiment, crazy, bold, and creative."

"And it's very informative, not bad!"

"not bad!"
