The discovery of the "Tesla" parasite gave Todd a new breakthrough in microbiology and gave him new ideas in laboratory equipment.

The existing optical microscope in the laboratory is the second microscope he made (the first one was given to Tristan), with a maximum magnification of 400 times, coupled with the "Eagle Eye" power, the magnification can reach 2500 times .

This magnification microscope can observe bacteria and chromosomes (you need to stain with gentian violet solution or acetate magenta solution), but if you want to observe viruses and other smaller substances, optical microscopes are powerless, and electron microscopes must be used. Render the image.

Because the overall size of the virus is generally 30-80 nanometers, if you just want to see it, you can see it by magnifying it 10,000 times. But if the viruses are clustered together, they need to continue to magnify to 50,000 to 100,000 times in order to effectively observe a single virus. If you want to clearly identify the shape of the virus, you need to continue to enlarge it by 100,000 to 150,000 times.

The discovery of the "Tesla" parasite gave Todd the basic materials for making electron microscopes.

For example, "Transmission Electron Gun Microscope" and "Scanning Tunneling Microscope". Due to the difficulty of manufacturing, the materials science and engineering technology of Muxi Town has not reached the corresponding level. Todd had to manufacture the equipment, positioning it at the most advanced level. On the simplest "Magnetic Force Electron Microscope".

The magnetic force electron microscope is the first product of the electron microscope. It was invented by Hans Bush in 1926 in the previous life. If the principle is described in popular language. First build a shell made of soft magnetic material with an inner annular gap, and then build an electromagnetic coil inside. When the coil is energized, electrons will move along the axis of the coil, and magnetic induction will be slowly generated. As the current increases, the magnetic induction intensity is strengthened, and the pattern that the electromagnetic lens focuses and imaged will become clearer and clearer. The sample under the sight glass will be magnified and appear in the eyepiece.

The main principle is this. As for other accessories and theories, such as vacuum pumps, diffusion pumps and vacuum valves, suction pipes, material slicers, and the wave-particle duality of light, Lorentz force, electromagnetic induction, and the theory of osmic acid dyeing, here I won't repeat them one by one.

Now let’s talk about the materials of the electron microscope. The most critical electromagnetic coil can be replaced by the "Tesla" parasite, but the construction of the soft magnetic material shell and the electromagnetic lens requires all the scholars, craftsmen and alien species in Muxi Town to be mobilized. finished.

After Todd examined Cosette’s body and asked her to discharge an appropriate amount of electricity according to the condition of her body every day, a technical conference was held in the headquarters of the Knight Order specifically for the manufacture of magnetic force electron microscopes. Participants included monks Joe and You. Lisis, Lynn, Elder Aiden, and Rachel.

After nearly two hours of explanation, the participants whispered and gave Todd an answer that made him fall apart.

"My lord, we don't understand what you are saying..."

When Todd cheered up, he asked everyone what he didn't understand.

The people in the audience looked at each other and gave him another answer that made him desperate.

"Since you talked about electricity and magnetism, we couldn't understand..."

Todd slapped his right hand heavily on his face, looking unlovable. It was only then that he remembered that the concept of electric current should be the American scientist Franklin in 1732; the summary and induction of electromagnetic phenomena should be Maxwell in the second half of the 19th century.

Now I want to use only two hours to let these people in the Middle Ages learn and understand electromagnetic theory, which is tantamount to idiotic dreams.

"Master Chief, I heard someone mention the electricity and magnetism you talked about." Ulysses' speech made Todd, who was in the bottom of his heart, saw a glimmer of light.

"Hurry up, who is it?"

"Abu Ben Sabah Kendi."

When he walked into the conference room of the headquarters of the Knight Order and saw the electromagnetic model and calculation formula painted on the wooden board, Kendy's eyes looked like a leopard that had found its prey at night.

The excited Abbasid scholar pointed to the wooden board, and a large string of Arabic came out of his mouth.

Todd frowned, and talked with him in lingua franca on electromagnetic principles. The more he talked, the more frightened he became.

Kendy said that his friends had put forward similar theories, but they were not so complete and rigorous. These southerners once rubbed fur products and metal glass together to produce electric sparks that can ignite paper scraps. They even gave the crackling flash an Arabic name-"raad", which means lightning.

Todd looked at Kendy eloquently, and finally remembered that in the Middle Ages in the previous life, the Arabs seemed to be the first ethnic group to understand the nature of lightning. They recognized other sources of electricity before other ethnic groups. At the end of the 14th century and the beginning of the 15th century, they even wrote a book on the analysis of electrical and magnetic energy, which was unfortunately lost in the subsequent wars.

Todd and Kendy talked for almost an entire hour. What made the former overjoyed was that although there were some mistakes in the other's understanding of electrical and magnetic energy, they were more about bold assumptions and reasoning close to the truth.

Todd eventually established a "Magnetic Force Electron Microscope" manufacturing team, Kendy served as the team leader, Ulysses, Lynn and students joined as researchers, the monks were responsible for the search and provision of books, and Ritchell was responsible for the manufacturing process. With the support of the middle power, the old Aiden is responsible for the manufacturing engineering.

Handwritten a document, asking the manager of the Holy Library, Queen Mary, to fully support the work of the manufacturing team. Todd finally signed his name and stamped the seal of the Knights. To leave a room of people caught up in discussions and disputes, the commander of the Knights has another important task to do.

The logistics cargo ship of Beidao Seafood arrived at the west coast of Twilight.

These large cargo ships carrying the flags of the Talon Tribe and the Black Skull Tribe have attracted the attention of the defense forces of Muxi Town. UU Reading www.uukanshu.com Alfonso led the Muxi Town security team to the beach for the first time, and apart from anything else, he encircled the North Island pirates who were responsible for the delivery.

After half an hour of confrontation, Todd's arrived in time, finally letting the two sides at ease relax.

On the one hand, he asked Alfonso to take the alien soldiers to the warehouse behind the experimental building to fetch the dormouse with the "freezing" ability; on the other hand, Todd talked with Morgan, who was in charge of the delivery, and the claw warriors. stand up.

This time the seafood was loaded with five large ships, totaling 129 tons. In addition to the goods, in order to keep the goods fresh, the North Islanders also accumulated a lot of ice in the cargo hold, but now there is not much left that has melted. If the "bacterial cold storage" is not installed, once the seafood deteriorates**, all efforts will be in vain.

Todd first confessed to Morgan's intention to purchase food in Musi Town, then commanded the soldiers in Musi Town to place dormouse cages in the cabin, and finally told the North Islanders how to use the "cold storage" and precautions.

After working for a long time, watching the five North Island cargo ships set sail again and heading south, Todd took a deep breath. I secretly said in my heart, whether the trade route of North Island-Muxi Town-Southern Empire can be opened up depends on the result of this fleet. (https://)
