The dragon skin and dragon tendon compensated by the Black Dragon King belongs to a transformed female dragon. The transformed dragon can change thousands of times, but cannot change its gender. Luo Ying still cannot change Xiao Jiji back. The only change is that he can finally change his appearance freely and no longer fix it into a face.

Luo Heng was angry and had eaten two hot pot meals before he could calm down, but he decided: "Mobak, Longsad, within the next ten years, I will cook the Dragon Island and remove the bones and fry the Black Dragon King."

"Yes, your majesty, your will is the direction we are moving forward." Mobak and Longsard and other undead lichs responded in unison.

Buckbruske probably never thought that he was hated by Luo Qin because he gave a corpse of a female transformed dragon. If he had known this, he would have given a male.

After dealing with this matter, Luo Qing then remembered another thing: "Hey, where are those human envoys?"

Mobak floated a few steps forward and said, "Your Majesty, because of the Black Dragon King's emergency, the reception dinner that was originally planned to be held after the exercise was cancelled, but the human envoys did not have the heart to enjoy the food. They said goodbye and left one after the exercise, and they couldn't even hold on."

"Oh? Haha, it seems that the exercise was effective, and it was scared away?" Luo Qing asked.

"Yes, I was scared away. When I left, several of them were still weak in their feet and stood up straight. After all, such a violent explosion... No, after all, His Majesty's posture is so majestic, it is normal for everyone to be scared to their legs." Mobak said in an admiring tone.

Although Mobak changed his words in time, Luo Ying still heard it. It was obvious that he was scared by the explosion. However, such an explosion could not kill the King of Steel Bone, and it also shocked them.

"Also, Kearns has printed the entire exercise process, hoping to get your permission to collect and publish them and display them publicly," Mobak said again.

Luo Qing blinked in confusion: "Rubbing? Show? What's it?"

Mobak quickly presented something like a picture album, one by one, one by one, one by one, but the details were not as rich as images on the paper.

"How did this be done? So real?" Luo Heng was surprised. In addition to the lack of details, the image was as vivid as a photo. Could it be that Carnes was also a time traveler with a two-megapixel black and white camera on his hand?

Of course, Mobak couldn't answer, and soon called Karns over.

"Your Majesty, this is a space printing machine, which can rub the patterns shot from here onto paper." Kahns hugged a square box with such a wide shoulder and introduced it to Luo Xu.

"Like this, put the rubbing material on the bottom, carry it at the object you want to rubbing, and pause for a few seconds to rubbing it down." At this point, Karns suddenly said to Luo Xu with emotion:

"Thanks to the paper invented by Your Majesty, when I used sheepskin rubbing, I had to fix it for a few minutes each time. The objects being rubbed cannot move during this period, otherwise it would be blurred. When rubbing people, the rubbing object would often fall asleep bored."

Isn’t this the silver-salt glass negative rubbing machine when the rubbing machine was first invented? It was actually rubbed directly onto paper.

Luo Qin swept his mind and found that the structure was quite simple. It was a small hole imaging device, and the light passed through the crystal ball in the middle and then projected onto the paper at the bottom.

The core of its technology is mainly on this crystal ball, with magic runes engraved with light-typed runes, which allow the light that penetrates the past to oscillate at high frequency, thus having the ability to etch on paper.

In principle, it is a combination of a small hole imaging device and a laser etching device, and the concept is very clever.

"Did you invent this machine?" Luo Qing asked.

Karns shook his head: "It was the senior sister invented it."

"Crotina!" Luo Ying shouted.

A small hole opened in front of Luo Qin, then squeezed hard to the size of a washbasin, revealing Crotina's face: "What do you want me to do?" This severely dead home girl was unwilling to go out even if she called her Majesty. She opened a space crack and showed her face.

However, the larger the space crack opens, the more energy it consumes. After revealing its face, the crack retracts back to the size of the original small hole, but the sound can still be transmitted.

"Have you applied for a patent for this thing?" Luo Qing asked.

"What is the patent? Is it delicious?" Crotina responded.

After explaining and letting her understand the meaning of the patent, Luo Zhao said: "The patent is not delicious, but only with a patent can you earn money to buy delicious food. You now owe Melissa's reincarnation fee of 100 Soul Crystals, my living expenses of fifty Soul Crystals, and Teddy's intestinal lump removal surgery fee. If you don't make money, you will soon have no money to buy things and eat."

"I apply, my majesty, I apply immediately." With no money to buy something, Crotina immediately became anxious. The sound coming from here was vague, and it sounded like something was stuffed in her mouth.

"It's great, but your printing machine still needs to be improved. First, the volume needs to be reduced, and second, the printing time needs to be shortened. I will ask the paper mill to make you a batch of negative paper with a single side with a photosensitive coating to make the etching of light faster."

There are many things in this world that are particularly sensitive to light systems, such as undead creatures. If you look carefully, you can find the photosensitive material. When applied to the paper, you can speed up the etching speed.

Crotina's embarrassing voice came from the hole: "Your Majesty, this thing was invented with a flash of inspiration. Improvement is not my specialty. Otherwise, I will authorize you the patent and you can find someone to improve it."

"Okay, the authorization fee will be settled at that time." Luo Ying did not force it and summoned Ryanhart, Carter, and the Great Sages over.

The great sage is knowledgeable and naturally knows what is particularly sensitive to light, with a large quantity and low cost, such as fluorescent moss, a kind of moss growing in caves and underground light-free environments. Its juice is particularly sensitive to light and will be inactivated after irradiation. At the same time, it presents different light changes according to the intensity of the irradiation.

This also brings another benefit, the images taken have certain color changes.

Ryanhardt redesigned the main body of the camera. He expanded the hole according to Luo Ying's suggestion and accurately refracted the light into the crystal ball through different combinations of crystal lenses.

This will achieve the effect of increasing the amount of light inflow and accelerating the etching speed. At the same time, it can also focus and make the printed objects clearer.

After some improvement, a printing machine similar to the size of a SLR in his previous life was completed.
