Alien Knights

　　 Karin's arrival left Todd at a loss.

　　 First, he really didn’t know how to arrange the girl’s shelter and food; second, he also vaguely felt that the other party's running away, perhaps related to the conversation yesterday, he should more or less bear some responsibility.

　　 The girl didn't pay much attention to his thoughts. After walking around in the monastery, she planned to use a mass room next to the underground hall as a temporary residence.

　　 After seeing it, Todd immediately expressed his opposition. Let’s not talk about whether it is appropriate to let a young girl live under the tomb. The dark, dampness and occlusion of the room give him enough reason to find another place for her.

After 　　, the monk apprentice plans to let Karin live in the village at the foot of the mountain, so that the distance is not too far and not conspicuous. But the other party asked him to live near the laboratory, which made him extremely big.

　　 Finally, Todd thought of a helpless solution.

　　 He tried his best to find a few sets of monk robes and asked Karin to disguise as a monk so that she could move freely. Then I planned to secretly vacate a room in the attic of the monastery library that was used to store the scriptures as the girl's bedroom. Ignoring the way Hudgens laughed after he learned of this idea, Todd, with the help of a few people, finally helped her move home in the middle of the night.

　　 In the following days, the monk's underground experiment will no longer work alone. He has a female assistant who is pleasing to the eye but mischievous and difficult.

Whether in the past or the present, Todd felt that the teaching interaction between teachers and students was so laborious for the first time. It is undoubtedly an arduous and long journey for a person whose life is lagging behind thousands of years to understand cross-age technology. .

　　 "You mean, our world is made of small particles?"

　　 "Kalin, the word I use is numerator."

　　 "Well, divide... sub, what a weird word."

　　 Todd fiddled with the flask in his hand and said without turning his head back: "In addition to molecules, there are atoms. Molecules can make up matter; atoms can make up molecules or matter directly."

　　 The girl scooped up the powder in the jar with a spoon, and asked: "Will we be able to see the molecules and atoms when we complete the microscope?"

　　 Todd laughed: "No, no, we made an optical microscope. To see molecules and atoms, you must use an electron microscope."

　　 "Then why don't we make an electron microscope directly?"

"Um...no...it's not a problem that we don't want to make, but...we can't make it. First of all, we have to solve the problem of electricity... Alas, Karin, forget the molecules and atoms I said, maybe we should look closer. After making this microscope, I can first show you some small animals that are invisible to the naked eye, such as cells or whipworms."

　　 The girl was obviously dissatisfied with this perfunctory statement, her mouth closed, annoyed, and she hit the powder in the bowl with a grinding stick.

　　 Seeing her performance, Todd could only sigh heavily.

　　 has been busy for eleven days, trying hundreds of times of raw material purification, material ratio, mixed firing, and decontamination and impurity removal. After countless failures. Todd finally confirmed the best optical glass manufacturing process.

　　 The first step is the most basic glass raw material ratio, adding soda ash, limestone, quartz and other materials according to the ratio.

　　 In the second step, boron oxide is added to increase heat resistance and chemical stability, so that the melting temperature of the glass is lowered, and it can resist sodium vapor corrosion.

　　 In the third step, a small amount of silver chloride is added to increase the optical sensitivity of the boronized glass.

　　 In the fourth step, a very small amount of copper oxide is added as a sensitizer to adjust the optical reaction speed of the glass.

　　 The fifth step is sintering, heating the prepared raw materials at a high temperature to form a uniform, bubble-free molten glass.

　　 The sixth step is forming, pour the glass solution into the pre-prepared mold and wait for it to solidify and shape.

　　 The seventh step is annealing, the gradually solidified glass is slowly cooled to room temperature.

　　 The last step is also the most difficult step.

　　 polish the lens. Use natural emery to carefully polish the surface of the lens to ensure the light-gathering ability and imaging accuracy of the lens. Since there is no professional optometry equipment and light sensing equipment, Todd can only use the most primitive direct light measurement method to manually polish the lens. Due to the problem of low proficiency and low matching, it took him five days to grind out a product that could barely be used.

　　 The eyepiece is only 5 times and 10 times, and the objective lens is only 10 times and 40 times. This figure is still manually measured, and there are still great errors.

　　 Condenser was too late to make a mirror, so I had to replace it with copper.

　　 There is no lathe (actually because he doesn't understand mechanics) and can't make mechanical knobs, so he uses the card slot to adjust the height.

The 　　 observation deck is a simple wooden shelf.

　　 After Todd made this simple and ugly microscope by himself, his first thought was not to cheer, but to redo it. It took a lot of work before he suppressed this impulse in his heart.

　　 Not only did Karin have no dissatisfaction with this device that took a lot of hard work to manufacture, on the contrary, when she put her hair on the observation platform, the girl suddenly felt that it was the greatest invention in the world.

　　 Todd made a microscope, naturally, it was not as simple as observing hair.

He took a hand blood sample from Huggins and a leg tissue sample from Edgar. After adjusting the magnification to 400 times, he was finally able to see the true origin of the two people’s heterogeneous abilities-bacteria . Originally, he planned to try to discuss with Karin to extract her body fluid for testing, but when the other party heard the disgusting expression of the word sampling, UU reading www.uukānshu.com made him immediately dismiss this idea.

　　 Put the samples of Huggins and Edgar into the glass slide, and then adjust the eyepiece, objective lens and viewing distance. Due to the limitation of the magnification effect, the bacteria under the microscope are only the size of a needle tip, and the specific morphology and structure cannot be observed at all, so it is impossible to carry out intracellular inspection and alienation test of bacteria.

　　 temporarily gave up studying the bacteria in the two of them, and then Todd put his gaze on himself-Sutherland's relic.

　　 After testing the blood to be nothing unusual, Todd, unwilling to give up, finally found two distinct bacteria in his lacrimal gland secretion and tooth nerves.

　　 The bacteria in the lacrimal gland move more actively, divide more steadily, iterate faster, and have a larger number. They mainly exist in the position of the retina and lens. He concluded that this may be the source of the ability to see through objects.

The globular bacteria in the nerves are very strange. They are very few in number. They can only be seen occasionally under the microscope. They are resistant to high temperatures and thermophilic. They will not damage the cell structure even if exposed to acid and alkali for a long time. . In addition to appearing to be unable to regenerate and divide, this bacterial body is very similar to the archaea (Domain-Archaea) of the previous life.

　　 There should be nothing wrong. The globular bacteria in the nervous system is the true face of Sutherland's relic.

　　 But there are new problems again.

　　 1. The bacteria on the eyeballs gave me the ability to "see through", so what is the role of Sutherland Archaea?

　　 2. If Sutherland archaea were infected by themselves in the cellar, when did the "perspective" bacteria in the eyeball enter the body?

　　 What people did not expect was that these two mysteries were completely solved in the next experimental accident.
