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 from home may be related to yesterday's conversation, and he should bear some responsibility.
The girl didn't pay much attention to his thoughts. She walked around the monastery and decided to use a mass room next to the underground hall as a temporary residence.
After Todd saw it, he immediately expressed his objection. Let's not talk about whether it is appropriate to let a young girl live under the tomb. The dark, damp, closed and stuffy room alone gave him enough reasons to do it for her.
Find another place to live.
After that, Todd planned to let Karin live in a village at the foot of the mountain, so that it was not far away and not conspicuous. However, the other party asked to live near the laboratory, which made him extremely troubled.
Finally, Todd came up with a helpless solution.
He tried every means to find several sets of monk's robes, and asked Karin to disguise herself as a monk so that she could move freely. Then he planned to secretly use a room in the attic of the monastery library, which was used to store scriptures, as a girl's dormitory. He ignored it.
Huggins laughed heartily when he learned about the idea. Todd, with the help of several people, finally helped her move her house late one night without any danger.
In the days that followed, Todd no longer worked alone in his underground experiments. He was joined by a female assistant who, although pleasing to the eye, was naughty and difficult to deal with.
Whether it was in his previous life or in this life, it was the first time that Todd felt that the teaching interaction between teachers and students was so difficult. For a person whose life is lagging behind for thousands of years, it is undoubtedly an arduous and long journey to understand the cross-generational technology.
.
"You mean, our world is made up of tiny particles?"
"Karin, the word I use is molecule."
"Okay, divide..., such a strange word."
Todd fiddled with the flask on hand and said without looking back: "In addition to molecules, there are also atoms. Molecules can constitute matter; atoms can constitute molecules, or they can directly constitute matter."
The girl scooped up the powder in the jar with a measuring spoon and asked, "When we build the microscope, will we be able to see molecules and atoms?"
Todd laughed: "No, we can't. We are making an optical microscope. If you want to see molecules and atoms, you must use an electron microscope."
"Then why don't we just make an electron microscope?"
"Um... no... it's not that we don't want to make it, but... we can't make it, so we have to solve the problem of electricity first... Sigh, Karin, forget about the molecules and atoms I mentioned. Maybe we should look at
Get closer. After building this microscope, I can first let you see some small animals that are invisible to the naked eye, such as cells or whipworms."
The girl was obviously dissatisfied with this perfunctory statement. She pursed her lips and hit the powder in the bowl with a grinding stick in annoyance.
Seeing her performance, Todd could only sigh heavily.
After eleven busy days and hundreds of attempts at raw material purification, material proportioning, mixing and firing, and decontamination and impurity removal, Todd finally confirmed the best optical glass production process.
.
The first step is the most basic glass raw material ratio, adding soda ash, limestone, quartz and other materials according to the proportion.
In the second step, boron oxide is added to increase heat resistance and chemical stability, lower the melting temperature of the glass, and resist sodium vapor corrosion.
The third step is to add a small amount of silver chloride to increase the optical sensitivity of boride glass.
The fourth step is to add a very small amount of copper oxide as a sensitizer to adjust the optical reaction speed of the glass.
The fifth step is melting, where the prepared raw materials are heated to high temperatures to form a uniform, bubble-free glass liquid.
The sixth step is forming. Pour the glass solution into the prepared mold and wait for it to solidify and form.
The seventh step is annealing, which slowly cools the gradually solidified glass to normal temperature.
The last step is also the most difficult step.
Polish the lens. Carefully polish the surface of the lens with natural emery to ensure the light-gathering ability and imaging accuracy of the lens. Since there is no professional optometry instrument and light-sensing equipment, Todd can only use the most primitive direct light measurement method to polish the lens by hand.
.Due to the problem of low proficiency and matching, it took him five days to polish a barely usable product.
The eyepiece is only 5x and 10x, and the objective lens is only 10x and 40x. These numbers are still measured manually, and there is still a huge error.
Because there was no time to make a mirror for the condenser, it had to be replaced with copper.
He couldn't make a mechanical knob without a lathe (actually because he didn't understand mechanics), so he used a slot to adjust the height.
The observation platform is a simple wooden frame.
When Todd made this extremely simple and ugly microscope, his first thought was not to cheer for joy, but to remake it. It took him a lot of effort to suppress this feeling in his heart.
impulse.
Not only was Karin not dissatisfied at all with this device that took a lot of effort to create, on the contrary, when she put her hair on the observation platform, the girl suddenly felt that this was the greatest invention in the world.
Todd built the microscope not simply to observe hair.
After taking a hand blood sample from Huggins and a leg biopsy sample from Edgar, and then adjusting the magnification to 400 times, he was finally able to see the true origin of the two's alien abilities——
Bacteria. Originally, he planned to discuss with Karin to extract her body fluids for testing, but the disgusted look on her face when she heard the word sampling made him immediately give up the idea.
Put Huggins and Edgar's samples 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 pinhead, and the specific shape and structure cannot be observed at all.
In this way, intracellular inspection and dissimilation testing of bacteria cannot be carried out at all.
Temporarily giving up on studying the bacteria in the two people's bodies, Todd then turned his attention to himself - the Sutherland relic.
After testing his blood and finding nothing unusual, Todd finally found two completely different bacteria in his tear gland secretions and tooth nerves.
The bacteria in the lacrimal gland are more active, divide more stably, iterate faster, and are larger in number. They mainly exist in the retina and lens. He deduced that this may be the source of the ability to see through objects.
The spherical bacteria in the nerves are very strange. They are very few in number. Only a few can be seen occasionally under the microscope. They are high temperature resistant and thermophilic. They will not damage the cell structure even if they are exposed to acid and alkali environments for a long time.
.In addition to appearing unable to regenerate and divide, this bacterial body is very similar to the Archaea (Domain-Archaea) in its previous life.
There should be nothing wrong, the spherical bacteria in the nervous system are the true identity of Sutherland's relics.
But a new problem came again.
1. The bacteria in the eyeballs give them the power of "see-through". So what is the role of Sutherland archaea?
Second, if the Sutherland archaea was infected by itself in the cellar, then when did the "see-through" bacteria in the eyeballs enter the body?
What people didn't expect was that these two mysteries were completely solved in the next experimental accident.
