Alien Knights

　　 At nine o'clock in the morning, the sunlight outside the window has filled the room. Todd lies on the bed with his eyes open, and the scene from last night is still playing back in his mind.

　　 The contact was only ten seconds, there were no words, no greetings, but Black Sheep made him feel like an old friend he hadn’t seen for a long time.

　　 When the girl returned to the stage and accepted the cheers of the audience, Todd chose to leave, not waiting outside the tent, nor looking back at the gorgeousness in the dark. Perhaps this has something to do with the character of his previous life. When he encounters good and happy things, he always has to leave a light leeway. Too much contact will only destroy the beauty of his first acquaintance. Don't allow yourself to indulge. It has always been so restrained.

　　 shook his head, smiled self-deprecatingly, sentimentality is not a good thing. The monk sat up from the bed, put on his clothes, brought a notepad, gave up the idea of ​​reading in the morning, and walked directly to the underground laboratory below the cemetery.

"Let me see, the sorting of materials in the laboratory is basically over. The next step is to make equipment for biochemical experiments. First of all, what we need to do is..." While flipping through the notes filled with text in his hand, he opened it with the key on his waist. Closed the door of the laboratory.

　　 A small sound of stone impact came from the inside of the room. Todd, who raised his head, looked forward, and a figure he had never expected appeared in his sight.

Wearing a light white round cake-like headdress, long black hair is combed to the back of the head, tied into two braids and hanging down along the cheeks. The loose-fitting blouse with the front open-breast naturally adheres to the body that is not fully developed. The sheep was sitting on the marble experiment table, two cowhide lacquer boots swinging back and forth.

　　 Todd opened his round eyes and stammered: "You... why are you... not... you are not..."

The black sheep looked at the table with interest, filled with all kinds of equipment and weird vials, picked up a dark vial sealed with metal glass material and wax, and slowly read the label in jerky Latin. On the text.

　　 "Strong...sulfur..."

　　 "No! Don't move that!"

　　 hurriedly threw the objects in his hand at the door, Todd dashed to the girl, just about to reach out and grab the vial.

　　 With a flick of the girl's finger, a small stone hit the wall at the other end. Her figure disappeared and instantly appeared where the stone fell.

　　 Knowing that this method of chasing her was useless, Todd opened his hands and said in a nearly pleading tone: "Miss Black Sheep, please give me the bottle in your hand."

　　 The girl was stunned when she heard the appellation in the other person’s mouth, then she rubbed the mouth of the bottle with her finger and asked, "What is this?"

　　 Seeing the monk hesitate and keep his mouth closed, the black sheep smiled mischievously and scraped the sealing wax layer by layer with his fingers, blinked, and was about to twist the bottle cap.

"Concentrated sulfuric acid!" Seeing the other party's movements, Todd's brain tensed, and hurriedly said: "A highly corrosive strong mineral acid, which can cause burns to the skin, and the resulting mist can cause blindness. In short, it is a kind of Something very dangerous. Now, please give it to me..."

　　 got the bottle, just when Todd thought he could breathe a sigh of relief, he saw the black sheep open the cap of the black powder bottle, immediately covered his forehead with a headache, and sighed heavily.

　　————————

　　 An hour later, after confirming that the other party was led by Huggins and not malicious, Todd taught the girl what to touch and what to not move, and then followed him to turn on the kerosene lamp, ready to start today's experimental life.

　　 A pair of dark eyes dangling around him, watching him weighing powder, mixing reagents, diluting air, and heating and filtering. Todd shrank his head a little uncomfortably, and said, "Could you please not stare at me like this while I'm doing experiments?"

　　 The girl holding her chin did not evade, but asked him: "Are you an alchemist?"

　　 After thinking about the rationality of this title, Todd nodded first, then shook his head.

　　 "I don't look like it, I have seen those alchemists, what they do is boring and dull, you look much more interesting here."

　　 The monk raised his eyebrows, and said in his heart that it was natural.

　　 The girl started chatting with him for a while.

　　 Todd, who was concentrating on the experiment, slowly let go of his guard, and unconsciously began to introduce what he was doing.

　　 "In this room, although there are so many equipments, if you want to actually perform the experiments I want, you still need a lot of cutting-edge equipment and precision instruments. The equipment I am making now is a microscope."

　　 "Microscope?"

Gradually found the feeling of teaching students in the laboratory class in the previous life. Todd separated his left and right hands to a distance of about 25 cm. It can distinguish between two objects 0.1 to 0.2 mm apart, which is probably slightly thicker than the hair. In other words, when the two objects are less than this distance apart, the human eye will treat them as one object."

　　 "Really? I will try." The girl really pulled out a hair and put it in front of her. UU reading www.uukanshu.com tried to tell the difference.

　　 "With a microscope, I can magnify things 100 or even 1000 times, so that I can see many things that I couldn't see before."

　　 The black sheep heard the other party's words, his eyes lit up, happily grabbed the edge of the table with his hands, and shouted: "What are you waiting for?! Do it now!"

　　 Todd put down his hands and shook his head helplessly: "How easy is the manufacture of microscopes, the most troublesome thing is the manufacture of lenses. The manufacture of lenses requires the production of optical glass first."

　　 The girl was confused again: "I have heard of glass. I heard that it is a treasure secretly made by craftsmen in the southern part of the mainland, but what is a lens?"

　　 After hearing this, the monk apprentice didn't know how to answer. Lens involves the principle of optics, which is not a theory that can be explained in one sentence; and optical glass is not something that can be made by setting a pot on the seaside and burning sand in a movie or novel; those craftsmen in the South create He has also seen the glass, the production process is really too bad, completely unable to meet the requirements of optical glass.

　　 While briefly explaining the production process to the girl, while watching the light flashing in her eyes, Todd finally realized why the black sheep gave him a familiar feeling.

　　 The girl's exploration of the world and the curiosity of things in the eyes of the girl reminded him of himself.

　　 When the sunlight refracted by the roof crack turned golden again.

The black sheep took a translucent crystal in the pot, pointed it at the sun in his hand, and looked at the colorful light scattered from it. While carefully putting it in his carry-on package, he stretched out to Todd. hand.

　　 "Mr. Todd, it was really a pleasant afternoon. I almost forgot the purpose of this trip. On behalf of the downtown circus, I extend an invitation to you, and I hope you will come back tonight."
