After graduating from public school, Lyle and his sister left the city of London in a horse-drawn carriage and returned to their home estate in the suburbs.

There is no doubt that this is a spacious and luxurious estate. But whether it is a self-made grandfather or a father who is more than a good manor, they all clearly understand that the same nobles also have high and low titles, and the small nobles should avoid the taboo and not overshadow the limelight of the big nobles, and there is no idea of throwing money into death to build a super manor, which can only be said to be 'ordinary luxury'.

The father controlled the family ship and sailed on the right course, but the mother who came from a down-and-out family was a loser, spending a lot of money on hiring maids, holding tea parties, and shopping...... Of course, the way the European aristocracy cultivated their daughters determined that it was not uncommon for the emergence of losers, and the mother was also just an 'ordinary loser'.

Fortunately, the 'ordinary loser' just spends money lavishly, not really throws money into the sea, some of the loser's behavior can get back a little bit of money in an emergency, some of the loser's behavior can open up contacts for the family, and some of the loser's behavior has a practical use.

"Sure enough, you are better~ The maids in the public school always feel stupid~" The maids in Lyle's house are a typical case of 'practical use', and under the high cost of investment, their appearance, service quality, and loyalty are far beyond the average.

Having lived in an aristocratic family environment since he was a child, don't expect Lyle to get out of the mud without staining, he is also a young man who lives a decadent aristocratic life, and even his meager living ability is obtained in boarding life...... cough, that meager living ability is still cleared with graduation and home, and it has become a waste scum that needs the help of a maid to get up and dress in the morning.

Lyle, who is overly dependent on maids, has a group of beautiful, capable, and loyal maids by his side, and his mother's money is not spent in vain.

"Young Master," asked one of the maids, who was setting up the guest room according to Lyle's instructions, holding a box with the lid open, "where are these glasses going to be placed?" ”

"Put it in the corner of the room first." Lyle hurriedly said, "These are 'lenses', but I specially made them for people, and they must not be broken." ”

"Understood." The maid answered, and immediately closed the lid of the box, and placed the box smoothly and neatly according to Lyle's request.

Another maid asked curiously, "Young Master, what are these 'lenses' for?" ”

Don't wonder why she asks her master questions that have nothing to do with work, the relationship between a mixed maid and a talkative nobleman is a delicate relationship between 'master and servant', 'family', and 'friend', not a cold and ruthless money-hire relationship, let alone a persecuted master-servant relationship similar to that of the emperor and the eunuch in the East.

This maid is not an ordinary grassroots maid, but Lyle is probably the most cordial and friendly nobleman to maids in Europe, and he has long been accustomed to such conversations and exchanges on weekdays.

"That's a tool for doing optical experiments, and it's also the basis for my future research, so it's a little complicated to explain~" Lyle replied with a smile.

"Experiments in light and optics? Belch...... That's still it. The maid was sensible and retreated.

There was a knock at the door behind me.

Lyle turned around and saw that it was the head maid who was supposed to be in the garden with her mother.

"Young master, the messenger arrived just now, and the master will probably come back in a week." Naturally, the letter was addressed to Lyle's mother, and the head maid had only come to take charge of relaying it.

"Tsk, there's no need to rush back......" Lyle flattened his mouth, this time his father's business trip was shorter than expected, "There's no way, the experiment is going to be intensified—can you arrange for me to be three maids as full-time assistants?" Also a horse-drawn carriage that may need to be used frequently. ”

Two of the maids are responsible for helping with the experiments, Lyle is very capable of doing experiments, but the literal 'hands-on ability' is very scummy, and he may accidentally knock over an alcohol lamp, and the last maid is responsible for going to the city to complete chores such as purchasing specific experimental props and finding craftsmen.

"Of course there is no problem." If you can't even complete the trivial task of vacating three maids and a carriage, the head maid can also abdicate and make way for Xian.

“……！” The maids who were busy in the guest room involuntarily stopped what they were doing and turned their heads to look at the head maid.

In European aristocratic circles, it was common for maids and masters to have abnormal intimacy, and despite the monogamy in Europe, aristocratic men often had mistresses and illegitimate children. And Lyle's kind attitude and handsome appearance towards the maids have actually made many female maids in the family willing to become 'mistresses' despised by the world.

The married maid chief knew the attitude of the young maids, and added firmly: "Young master, I will arrange three maids for you to be the most serious later." ”

As Lyle and Ami expected, his father, who had returned from work, did not approve of Lyle's efforts to devote his energy to the natural sciences and enter the process of convincing people with reason-

"Microscope?" The father raised an eyebrow.

"Please don't let my imagination be constrained by the image of a toy or a work of art, just because no one has put any effort into polishing high-magnification lenses, and when the magnification reaches hundreds or even thousands of times, it will be something completely different." Ordinary craftsmen will not try to make high-magnification lenses, although there is not a cliff-like technical obstacle, but the difficulty is quite high, but if there is a large amount of money to let them polish high-magnification lenses full-time, it is another matter.

"I think I can make a microscope with a magnification of 1,000 times." The father was puzzled, "But zooming in so much, what exactly do you want to see, Lyle, dust?" ”

"No, I want to see something smaller than dust." Lyle laughed, "The current medical theory has not really explained the cause of human disease, including the treatment, it is all empirical summary treatment...... I don't think that people get sick for no reason, the existence of infectious diseases is the best evidence, then I can only think that [the culprit that makes us sick is something invisible], this invisible thing may be transparent, or it may just be because we are too small. ”

“！” My father's body shuddered, and he thought of something terrible.

The Black Death, the disease that broke out centuries ago and continues to plague Europe to this day, is something that every European fears.

"I don't expect to make money selling microscopes, and the same goes for patents, and there are too few people who are involved in medicine." Lyle shook his fingers, "However, if I can see the 'culprit of the disease', I can find a way to eliminate this culprit, and the pharmaceutical industry will also undergo a big change...... Father, please give me a chance to verify. ”

Lyle doesn't think that the argument of 'saving the common people' can convince his father, so he can only use the pharmaceutical industry to make money.

“………… I'll give you two years," eventually, Lyle's father relented, "but! Don't even think about going to the epidemic area to find the source of the disease, contact the patient, and bring the patient home for treatment! ”
