Alien Knights

The discovery of the "Tesla" parasite gave Todd a new breakthrough in microbiology, and also gave him a new idea for 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, and combined with the ability of "Eagle Eye", the magnification can reach 2500 times.

A microscope with this magnification can observe bacteria and chromosomes (staining with gentian violet solution or acetic acid carmine solution is required), but in order to observe smaller substances such as viruses, optical microscopes are powerless, and electron microscopes must be used to present images.

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

The discovery of the "Tesla" parasite just gave Todd the basic material for making an electron microscope.

Such as "transmission electron gun microscope" and "scanning tunneling microscope", due to the difficulty of manufacturing, the material science and engineering technology in Muxi Town has not yet reached the corresponding level, Todd had to manufacture the equipment, and positioned it on the most elementary and simplest "magnetic force electron microscope".

The magnetic force electron microscope is the most primitive product of the electron microscope, which was invented by Hans Bush in 1926 in his previous life. The principle is described in plain language. First build a shell made of soft magnetic material (pure iron or low carbon steel) with an inner annular gap, and then build an electromagnetic coil inside. When the coil is energized, the electrons will move along the axis of the coil, and the magnetic induction will be slowly generated. As the current increases, the magnetic induction intensity is strengthened, and the focus imaging pattern of the electromagnetic lens will become clearer and clearer. The sample under the sight glass is magnified and displayed in the eyepiece.

This is the main principle. 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 osmium acid dyeing theory, I will not repeat them here.

Now let’s talk about the materials of the electron microscope. The most critical electromagnetic coil can be replaced by “Tesla” parasites, but the construction of the soft magnetic material shell and the electromagnetic lens needs to mobilize all the scholars, craftsmen and aliens in Muxi Town to complete it together.

After Todd checked Cosette's body and instructed her to perform an appropriate amount of discharge every day according to the internal condition, Todd held a technical meeting at the headquarters of the Knights for the manufacture of the magnetic electron microscope. The participants included Brother Joe, Ulysses, Lynn, old Aiden and Rachel.

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

"Master Chief, we don't understand what you said..."

When Todd got up his spirits, he asked everyone if he couldn't understand.

The people in the audience looked at each other in blank dismay, and gave him another answer that made him despair.

"Since you mentioned electricity and magnetism, we don't understand..."

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

It is tantamount to nonsense to let these medieval people learn and understand electromagnetic theory in just two hours now.

"My lord, the electricity and magnetism you mentioned, I once heard someone mention it." Ulysses' speech made Todd, whose mood sank to the bottom, see a glimmer of light.

"Tell me, who is it?"

"Abu ibn Sabah Kendi."

Walking into the meeting room of the Knights' Headquarters and seeing the electromagnetic model and calculation formulas drawn on the wooden board, Kendy's eyes looked like a leopard that found its prey at night.

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

Todd frowned, and chatted with him in common language about the principle of electromagnetism, and the more we talked, the more frightened we became.

Kendy said that his friend had put forward a similar theory, but it was not as complete and rigorous. These southerners once rubbed fur products and metal glass together, creating electric sparks that could ignite confetti. They even gave the crackling flash an Arabic name - "raad", which means lightning.

Todd looked at Kendi who was eloquent, and finally remembered that in the Middle Ages in the previous life, the Arabs seemed to be the first group to understand the essence of lightning, and they recognized other sources of electricity before other groups. At the end of the 14th century and the beginning of the 15th century, they even wrote works on the analysis of electric energy and magnetic energy, but unfortunately they were lost in the later wars.

Todd and Kendi chatted for almost an entire hour, and the former was overjoyed that although the other party's understanding of electric energy and magnetic energy had some mistakes, it was more of bold assumptions and reasoning close to the truth.

Todd finally set up a "Magnetic Electron Microscope" manufacturing team, with Kendy as the team leader, Ulysses, Lynn and the students joined as researchers, monks were responsible for finding and providing books, Rachel was responsible for the support of abilities during the manufacturing process, and old Aiden was in charge of manufacturing engineering.

A document was written by hand, requesting 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. Leaving a room full of discussions and arguments, the Grand Master of the Knights has another pressing job to do.

The logistics cargo ship of Beidao Seafood arrived at Muxi Coast.

These large cargo ships carrying the banners of the Talon and Blackhead tribes attracted the attention of Muxi Town's defense forces. Alfonso rushed to the beach immediately with the Muxi Town guards, and surrounded the Beidao pirates who were in charge of delivering the goods without saying a word.

After half an hour of confrontation, Todd arrived in time, and finally let the two sides who were tense at each other relax.

On the one hand, let Alfonso take the alien soldiers to the warehouse behind the small experimental building to fetch the dormouse with the "freezing" ability; on the other hand, Todd chatted with Morgan and the Claw Warriors who were in charge of delivering the goods.

A total of five large ships were loaded with seafood this time, totaling 129 tons. In addition to the goods, in order to keep them fresh, the North Islanders also piled up 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 explained to Morgan the intention of Muxi Town to purchase food, then directed the soldiers of Muxi Town to place the dormouse cage in the cabin, and finally told the North Islanders how to use the "cold storage" and precautions.

After working for a long time, Todd took a deep breath as he watched the five North Island cargo ships set sail again and head south. He thought to himself, whether the North Island-Muxi Town-Southern Empire trade route can be opened up depends on the results brought by this fleet.
