Chapter 42 Type I Wet Plate Camera

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

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

Li He didn't say anything about this.

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

Li He stretched out his hand, and three small test tube potions appeared in his palm.

The group of people stepped forward one by one, took the potion, and drank it.

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

Li He glanced at the people lying down, then looked back, opened the window of the room, and looked out at the street.

It can be seen that the streets of the small town are not lively after dark, with only scattered people walking around, either drunken traders, hunters, farmers, or pedestrians in a hurry and having urgent matters.

The only special thing was a man walking towards the end of the street. He was wearing a tuxedo and was quite aristocratic, causing the others to stay away unconsciously for fear of contradicting this noble man. He was none other than the devil Alex.

At this time, Devil Alex held a heavy box in each hand and walked towards the hotel. Seeing Li Hyuk looking out the window, he sped up and entered the hotel a moment later and entered the room.

"Bang bang!"

Putting the two heavy boxes on the floor, Alex 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 good, it seems we are going to be busy tonight. So let's not waste any time. Let's go. Take the materials and the six people 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 into the No. 1 laboratory of the main castle to get busy.

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

A few hours later.

In the No. 1 laboratory of the main castle, in a small room on the first floor that had been cleared out recently, Li He closed all the doors and windows and turned on the only light source - a lamp covered with a crimson glass shade.

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

Li He looked around, stepped towards a shelf in the corner, took off the glass plate that had been coated with photosensitive material, 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 five 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 He took out the "Book of Destiny" from another iron stand and placed it on the adjacent vibrator.

"Buzz——"

The vibrator vibrated rapidly, and words began to appear in the "Book of Destiny", which stabilized after a moment.

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

"Crack!"

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

"Crack!"

Another shot.

"Crack!"

Another shot.

"Pap tap tap tap tap tap..."

Continuous shooting.

After a moment, all the contents in "Book of Destiny" disappeared, and Li Hyuk stopped filming.

But he didn't stop busy. He collected the used glass plates as quickly as possible, put them into the developing tank next to them, and immersed them in the developing solution.

The photosensitive material applied on the glass plate begins to appear as an image under the action of the developer after being stimulated by exposure.

Under the crimson light, Li He opened his eyes wide and carefully observed the degree of impact on development. Once the desired effect was achieved, he quickly took it out and put it into the cleaning pool nearby. Use flowing water to wash away the excess developer to prevent excessive development and affect the final result. film effect.

After completing this step, Li He did not stop, and immediately put the glass plate into the fixing tank to fix the image and prevent future changes.

After the fixing is completed, take out the glass plate, put it into the second cleaning tank, and wash away the excess fixer with running water.

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

Finally apply the paint and finally get the perfect image.

Li He took a long breath, looked at the final product, and nodded with satisfaction.

…

Afterwards, Li Hyuk left the "photography darkroom", returned to the main research room, put the wet plate photography films on the test table, and began to carefully copy the contents.

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

The content captured this time with the Type I wet plate camera was more than ten times more than what the brain had worked so hard to memorize before.

"Shashasha..."

Li He held a quill and wrote quickly on the papyrus.

While transcribing, organizing and analyzing.

"The spell Scorching Flame Waterfall? Hmm, it looks very powerful, but it can't be used for the time being. Let's just keep it as a reserve of knowledge...shashasha..."

"Giant Eye 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 it must require human blood... Shashasha... "

"Death to the crow? It can sense the death event that is about to happen. Once it appears, it means unknown... If you can predict the future, what is the principle? If you have a chance, you can study whether it is true... rustle..."

"..."

Li He copied and analyzed the contents of the "photos" one by one.

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

"Records of Hybrid Breed Improvement Experiments (Continued)?!"

"There is actually a follow-up to the previously recorded experiments? Can the random knowledge this time be connected with the previous knowledge?"

"It seems that as long as enough content is recorded each time, it can be ensured that knowledge is no longer fragmented, but can be pieced together bit by bit into complete books and a relatively complete knowledge framework."

"Then let's see what information the so-called improvement test (continued) provided us this time."

Li Hyuk whispered, carefully transcribing and reading.

As the copying and reading progressed, Li He's expression became solemn, and his brows sometimes wrinkled and sometimes relaxed.

After a long while, he finished transcribing and reading. Li He looked at the contents on the papyrus and murmured to himself with twinkling eyes: "It's really a bold experiment, crazy, bold, and creative."

“And it’s of great reference value, not bad!”

"very nice!"
