Alien Knights

At nine o'clock in the morning, the sunlight outside the window had filled the whole room. Todd lay on the bed with his eyes open, still replaying the scene of last night in his mind.

The contact was only ten seconds long, without a single word or greeting, but Black Sheep felt like an old friend he hadn't seen for a long time.

When the girl returned to the stage and accepted the cheers from the audience, Todd chose to leave without waiting outside the tent, nor did he look back at the gorgeousness in the dark. Perhaps this has something to do with his personality in his previous life. When he encounters good and happy things, he always leaves a little room for lightness. Too much contact will only destroy the beauty of the first acquaintance.

Shaking his head, he smiled self-deprecatingly, being sentimental is not a good thing.

Todd sat up from the bed, got dressed, took a notepad, gave up the idea of ​​morning reading, and walked directly to the underground laboratory under the cemetery.

"Let me see, the materials in the laboratory are basically finished, and the next step is to make the equipment for biochemical experiments. First, the thing to do is..." While flipping through the notes in his hand, he opened the door of the laboratory with the key on his waist.

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

Wearing a light white round cake-style headdress, long black hair combed behind the head, tied into two braids and hanging down the cheeks, the open-front loose top naturally fits the immature body, and the black sheep lightly powdered sits on the marble laboratory table, and the two leather lacquer boots are swinging back and forth.

Todd opened his round eyes and stammered, "You...how are you...not...you are not..."

The black sheep looked at the table with great interest, which was full of all kinds of equipment and weird vials, picked up a bottle of metal glass, dark vial sealed with wax, and slowly read the words on the label in jerky Latin.

"Strong... sulfur..."

"No! Don't touch that!"

Hastily throwing the object in his hand at the door, Todd rushed to the girl in a stride, just about to reach out and snatch 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 at the place where the stone fell.

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

Hearing the address in the other party's mouth, the girl was stunned for a while, then rubbed the mouth of the bottle with her finger, and asked, "What is this?"

Seeing Todd's hesitant face and keeping his mouth shut, Black Sheep smiled mischievously and scraped off the sealing wax layer by layer with his fingers, blinked his eyes, and made a gesture to unscrew the bottle cap.

"Concentrated sulfuric acid!" Seeing the opponent's actions, Todd's brain tightened, and he hurriedly said: "A highly corrosive strong mineral acid that can cause burns to the skin, and the mist formed can cause blindness. In short, it is a very dangerous thing. Now, please give it to me..."

After getting 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 without malice, Todd taught the girl what to touch and what not to move, followed him to turn on the kerosene lamp, and was ready to start today's experimental life.

A pair of dark eyes dangled around him, watching him weigh powder, mix reagents, dilute gas guide, heat and filter. Todd shrank his head a little uncomfortable, and said, "Can you please stop staring at me like this while I'm doing the experiment?"

The girl holding her chin didn't have the slightest evasion consciousness, but asked him instead: "Are you an alchemist?"

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

"I don't think so. I've seen those alchemists. What they do is boring and dull. Yours looks much more interesting here."

Todd shrugged with a wry smile.

The girl started chatting with him one after another.

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

"In this room right now, although there are so many equipments, a lot of cutting-edge equipment and precision instruments are needed to actually carry out the experiments I want. The equipment I am making now is the microscope."

"microscope?"

Gradually rediscovering the feeling of teaching students in the laboratory class in his previous life, Todd separated his left and right hands to a distance of about 25 cm, and said to the black sheep: "Generally, at such a long distance, the human eye can only distinguish two objects that are 0.1 to 0.2 mm apart, which is about a little thicker than a hair. That is to say, when the distance between two objects is less than this distance, the human eye will regard them as one object."

"Really? I'll try." The girl really pulled out a hair, put it in front of her, and tried to distinguish it.

"And with a microscope, I can magnify things 100 or 1,000 times, so I can see a lot of things that I wouldn't otherwise see."

Heiyang's eyes lit up when he heard the other party's words. He happily grabbed the edge of the table with both hands and shouted loudly: "Then what are you waiting for?! Do it now!"

Todd put down his hands and shook his head helplessly: "How can it be so easy? The most troublesome thing in the manufacture of microscopes is the manufacture of lenses. And the manufacture of lenses requires the production of optical glass first."

The girl was confused again: "I've heard of glass. I heard that it is a treasure secretly crafted by craftsmen in the south of the mainland, but what is a lens?"

After hearing this, Todd didn't know how to answer.

The lens involves the principle of optics, which is not a theory that can be explained clearly in a few words; and optical glass is not something that can be made by setting a pot by the sea and burning sand in movies and novels; he has also seen the glass made by southern craftsmen, and the production technology is too poor to meet the requirements of optical glass.

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

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

When the sunlight refracted by the cracks in the roof turns golden again.

Hei Yang took a piece of translucent crystal in the cauldron, pointed it at the sun, looked intoxicated at the colorful light scattered on it, carefully put it into the package, and stretched out his hand to Todd.

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