The dragon skin dragon tendon compensated by the Black Dragon King belongs to a deformed female dragon, the deformed dragon can change thousands of times, but it can't change the gender, Luo Qiu still can't change the little chirp back, the only change is that he can finally change his appearance freely, and he is no longer fixed into a face.

Luo Qiu was angry and ate two hot pots before he was angry, but he still decided: "Mobuck, Longsad, in the next ten years, I will hit Dragon Island and fry the bones of that black dragon king." ”

"Yes, Your Majesty, your will is where we are headed. Undead lichs such as Mobuck and Lonzard responded in unison.

Bakhbrusk probably couldn't have imagined that he was hated by Luo Qiu because he gave the corpse of a female transformer dragon, and he knew that he would give it to a male.

After dealing with this matter, Luo Qiu remembered another thing: "Hey, what about those human envoys?"

Mobuck Piao took a few steps forward and said: "Your Majesty, due to the unexpected situation of the Black Dragon King, the reception dinner that was originally planned to be held after the exercise was cancelled, but the human envoys didn't have the heart to enjoy the food, and as soon as the exercise was over, they left one after another, and they couldn't hold it back. ”

"Oh, hehe, it seems that the exercise is working well, and it scared you away?" Luo Qiu asked.

"Yes, scared away, when I left, several of them were still limp and couldn't stand up straight, after all, such a violent explosion...... , No, no, after all, His Majesty's posture is so mighty, it is normal for everyone to be scared and weak. Mobuck said in a tone of adoration.

Although Mobuck changed his words in time, Luo Qiu still heard it, and dared to be frightened by the explosion. However, such an explosion could not kill the King of Steel Bones, and it also shocked them.

"Also, Kearns has rubbed the entire exercise and hopes to get your permission to publish and display them publicly. Mobuck added.

Luo Qiu blinked suspiciously: "What kind of rubbing?"

Mobuck quickly presented what resembled a picture album, a black-and-white photograph that was not as detailed on paper.

"How did this happen? So real?" Luo Qiu was surprised, except that the details were not rich enough, this image was as vivid as a photograph, could it be that Kearns was also a time-traveler, with a two-megapixel black and white camera in his hand?

Of course, Mobuck couldn't answer, and soon summoned Kearns.

"Your Majesty, this is a spatial rubbing machine, which can rub the patterns that shoot in from here onto paper. Kearns held a shoulder-wide square box and introduced it to Luo Qiu.

"Like this, put the rubbing material at the bottom, carry it at the object you want to rub, pause for a few seconds and then rub it down. Speaking of this, Kearns suddenly said to Luo Qiu with great emotion:

"Thanks to the paper invented by His Majesty, when I used to use sheepskin rubbing, I had to fix it for a few minutes each time, and the object to be rubbed could not be moved during this time, otherwise it would be blurred, and when I was 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?

Luo Qiu's mind swept over and found that the structure was also quite simple, 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, which is engraved with magical runes of the light system, so that the light that penetrates through the past vibrates at high frequency, so that it has 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 ingenious.

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

Kearns shook his head: "It was invented by Senior Sister." ”

"Crotina!" Luo Qiu cried.

A small hole opened in front of Luo Qiu, and then squeezed it hard to the size of a basin, revealing Crotina's face inside: "What are you looking for me?" This heavily dead house girl is not even willing to go out even when His Majesty is called, and opening a spatial crack will show her face.

However, the larger the spatial rift opened, the more energy was lost, and after revealing his face, the rift retracted back to the size of the original small hole, but the sound could still be transmitted.

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

"What is a patent, is it delicious?" said Krotina.

After explaining and letting her understand the meaning of the patent, Luo Qiu said: "The patent is not delicious, but with the patent you can earn money to buy good food, you now owe Melissa a hundred soul crystals for reincarnation, I owe fifty soul crystals for living expenses, and Teddy's fifty soul crystals for intestinal lumpectomy surgery, if you don't make money, you will soon have no money to buy food to eat." ”

"I apply, I apply, Your Majesty, I apply right away. As soon as she had no money to buy something to eat, Clotina immediately became anxious, and her voice was indistinct, sounding like she had something in her mouth.

"Very good, but your rubbing machine still needs to be improved, first, the volume should be reduced, and second, the rubbing time should be shortened. I'll ask the paper mill to make you a batch of negative paper with a photosensitive coating on one side to make the light etching faster. ”

There are many things in this world that are particularly sensitive to light, such as undead creatures, and if you look for them carefully, you can find light-sensitive materials, which can be applied to paper at that time, which can speed up the etching.

Crotina's embarrassed voice came from the small hole: "Your Majesty, this thing was invented by me in a flash of inspiration, and improvement is not my specialty, or I will grant you the patent, and you can find someone to improve it." ”

"Okay, the licensing fee will be set at that time. Luo Qiu didn't force it, and summoned Reinhardt and Carter, as well as the Great Sage.

The Great Sage is very knowledgeable, and naturally knows what is particularly sensitive to light, and the quantity is large and low, such as fluorescent moss, a moss that grows in caves and underground lightless environments, its sap is particularly sensitive to light, and it will be inactivated after irradiation, and at the same time, depending on the intensity of the irradiation, it will show different light changes.

This also brings another benefit, the resulting image has a certain color variation.

Reinhardt redesigned the main body of the camera, following Luo Qiu's suggestion, enlarging the holes and refracting light into the crystal ball through a combination of different crystal lenses.

In this way, it can increase the amount of light entering and accelerate the etching speed, and at the same time, it can also zoom and focus, so that the rubbed object is clearer.

After some improvements, a rubbing machine similar to the size of a DSLR in the previous life was completed.

Two months later, a huge army of immortals stepped out of the north gate of Motie City, wearing a sunscreen cloak, walking in neat steps, holding pieces of wooden planks printed with patterns, all the way to the north.
