Xie Minghuan's stay did not bring any changes to the people in the inn. This master of the rivers and lakes seems to be not well-known, or the people here are relatively lonely and unheard, in short, everyone only regards him as a man in the rivers and lakes who is so downtrod that he needs to sell horses, and he is not regarded as a master at all.

Time flies, in a blink of an eye, Wu Xie and Tao Tu have lived in Qingniu Town for half a month.

In the past half a month, they have traveled all over Qingniu Town and the nearby mountains and forests, getting acquainted with the more special characters in this town, and also getting to know other immortal seekers.

In addition to the eight people who live in the inn, there are also some people who directly rent or buy the houses of the residents in the town, as for the Wei Teng Wei Gongzi who once said with disdain that he didn't want to be disturbed by idle people, although he still lives on the third floor of the inn, but his family's craftsman has been renovating a yard that he bought not long ago, and he will probably move out soon.

The immortal seekers in the town came from all directions, and the farthest was Gu Yuan, who came from the Great Qin Kingdom in the northwest of Kyushu, and this young man who was only twenty-five years old had been trekking on the road to seeking immortals for ten years. He was in a similar situation to Wu Jie, he made up his mind to seek immortals after meeting an immortal by chance. However, he is not as lucky as Wu Jie, and he has not gained anything so far.

Among the immortal seekers, there are many children of rich families, in addition to Wei Teng and Tao Tu, there is also Liu Ming from Zhancheng, the capital of the Great Yue Kingdom. The Liu family has been in business for generations, and he is a famous wealthy businessman in Yue, and his real family wealth is very rich, but this Liu Gongzi is very kind, and he does not have Wei Teng's arrogance at all, and he is very easy to get along with.

Liu Ming naturally didn't go out alone to seek immortals, he had three retinues by his side. One is a scholar who has served him since he was a child, one is a guide who is familiar with the customs and customs of various places, and the other is a martial arts master.

That martial arts master is very good at kung fu, and on the second day of Xie Minghuan's stay, the two of them once did not agree with each other, and they fought indistinguishably. However, Wu Xie noticed that Xie Minghuan did not use the Broken Cloud Sword, the treasure of the Nine Swords Gate, at that time, and thought that with the arrogance of this master, he probably disdained to win with the divine sword in a single battle that was only tentative.

This battle was extremely fierce, and it also made those who originally looked down on Xie Minghuan's down-and-out martial artist change their color, and in the next few days, more than one person ran to deliberately befriend him, but they were all deflated - Xie Minghuan let the masters of the rivers and lakes not do it, and asked the immortals with an iron heart, how could he waste time to make friends with these characters that he didn't look down on?

There are also some people with eccentric personalities among the immortal seekers, for example, there is a Yi Gongzi who has lived in Qingniu Town for more than a year, who goes up the mountain every day to chop firewood, and lives a poor life with a little money earned from labor - but he often buys pen, ink, paper, and inkstone, and the ones he buys are still high-end goods, and he can see that his net worth is quite rich, but he doesn't know why he wants to live a hard life.

In addition to these immortal seekers, there are also quite a few residents in the town that are worth mentioning.

The first thing worth noting is, of course, the innkeeper who named his son "Li Xiaoyao", Li Mingtong. This uncle, who is nearly forty years old, has a kind round face, a slightly chubby figure and a blessed appearance, and shows a wide range of knowledge in ordinary conversations, and can be said to be the first person in the town to be well-informed.

Including Wu Jie, almost every immortal seeker had asked this uncle whose name was quite similar to a certain snack about the traces of the immortals, and they had also received a lot of news that seemed to be quite reliable.

It's just that I don't know what Lu Dao is for, almost all the news provided by this well-informed uncle is "there have been immortals in such and such a mountain", and the immortal seekers are running around because they heard his news, and they don't know how much Lu Dao has suffered.

It's the end of the first month, the coldest time of the year. Even most of the poisonous insects on the side of Dayue are still dormant, otherwise I am afraid that someone would have been bitten or even poisoned to death.

But the strange thing is that no one retaliated against him for this, on the contrary, everyone is still tirelessly going to the deep mountains and old forests to suffer according to the very suspicious information he provided.

“…… Yesterday, after Boss Li drank, he said that there was a demon beast iron-billed eagle on the side of the eagle's beak cliff more than ten years ago, and it was later beheaded by the immortals. While sorting out his luggage, Tao Tu explained to Wu, "Brother Liu and I plan to go over and have a look, even if we can't find the immortals, maybe we can see some traces of the original." Wu Daxia, are you going? ”

Wu Xie smiled and refused, left the inn alone, and came to the pharmacy.

Compared with Li Mingtong, the pharmacy owner Jiang An is simple but much more high-profile. This name reminds Wu Xie of the old gentleman of the final boss in a zombie movie he had watched before crossing is nearly sixty years old, but he looks just a handsome middle-aged man in his thirties.

Because of this, many immortal seekers insisted that he was a master of cultivation, and constantly pestered him for guidance and disciples, which made him tireless.

But Doctor Jiang is worthy of being a human spirit who has lived for sixty years, and it is much more difficult to ask for something valuable from his mouth than Li Mingtong!

Everyone who tries to talk to him will find that they obviously want to ask something, but after a few words, the topic is unconsciously brought to aspects that have nothing to do with seeking immortals, sometimes it is about maintaining the body, sometimes it is about the Nanban customs, and sometimes it is about the anecdotes of the apricot forest......

If this person's words are really powerful, he can't say the other party, he will simply leave the old face and muttered a golden knife barbarian - the old man was born in the extreme south, the small clan of the golden knife barbarian, the degree of isolation from the world is incredible, except for the clansmen in the deep mountains, people who can understand his mother tongue are afraid that they can count it with one hand.

Wu Xie was the only exception, because he never asked the general about seeking immortals, he only talked to the other party about medical skills.

Both sides are doctors, Jiang Ansheng has many years of experience in medicine, and Wu Jiesheng has several levels of knowledge of earth medicine ahead of this world, and what they are good at complements each other, and every time they discuss, they feel that they have gained a lot.

Through the discussion, Wu Xie learned a lot of tricks unique to the barbarians in the south of the Yue Kingdom, including some exclusive secret recipes with extraordinary medicinal effects, which are hard to change.

But what Jiang Shore obtained is even more precious - no matter how precious these secret recipes are, they are still circulated among various tribes after all, as long as they spend enough money and time, they can always be found, but the knowledge in Wu Jie's heart is a real exclusive product, unless there are other traversers in this world, no one will be able to understand.

These days, the only consolation that the general who has been harassed by the immortal seekers is that he can learn the knowledge that makes his heart suddenly open and opens the door to advanced medical skills for himself.

So as soon as he saw Wu Xie coming to the door, he immediately left behind a few immortal seekers who were still entangled, and entered the living room behind the pharmacy with Wu Jie.

"Little friend, the 'germ theory' you said is really an eye-opener for me!" He said excitedly, "I thought about it all night yesterday, and combined with a lot of experience in the past, the more I think about it, the more I think what you said makes sense!" ”

Wu Xie was not surprised at all by this, since the basic physical and chemical phenomena in this world are still consistent with the earth, then science in a general sense is naturally the same in this world.

Perhaps there are differences between the two worlds in some deeper and more critical places, but at least things such as "bacterial infection" should not be wrong.

What's more, during the disaster relief in Nanping County, practices such as "isolation", "disinfection", and "sterilization" have been proven to be effective. Since those practices worked, the germ theory should certainly be valid.

However, the expression on his face was indifferent, but he secretly muttered in his heart.

This general ...... How is it so easy to accept new theories? Shouldn't an old man of this age be a little stubborn?

"Little friend, but I also have a question." Jiang Kishi said, "Your theory is indeed very complete and can be verified with my medical experience, but theory alone is not enough, right?" According to your theory, there are some tiny insects in the world that are invisible to the naked eye, you call them, and they are the main culprits that cause many diseases, especially diarrhea and ulceration, so can you find a way to find them? ”

"What's so hard about that!" Wu Xie smiled slightly, asked him for the four treasures of the study, and drew a slightly rudimentary microscope on the paper.

There are three keys to microscopy, the first is the lens, the second is the bottom light, and the third is the lens tube. Once these three keys are solved, all that remains is the details such as focusing. In Wu Jie's view, although the scientific and technological level of this world is backward, at least it will not lose to the earthlings of the Ming Dynasty in terms of craftsmanship, and the earliest microscope seems to have been invented during the Ming Dynasty, so this world should be able to do it.

A simple optical microscope is not such a complicated instrument, Wu Xie drew while recalling, but he drew it in a quarter of an hour.

"Look at you, old man, this thing can magnify the appearance of subtle things twice, so that things that are not visible to the naked eye can be seen...... However, this thing is easier said than done, and if you are not a master who is proficient in this way, I am afraid that you will not be able to do it. ”

Shogishi took the drawings and looked at them carefully for a while, and asked questions such as "what can be enlarged for the sake of the skull". Wu Xie didn't hide his secrets, and explained the principle of the lens to him.

"It's a pity that the climate here is hot, and it doesn't freeze even in winter. Otherwise, I can use ice to grind a lens and demonstrate it live......" After he said the most, he sighed helplessly when he saw that Jiang Jian still didn't seem to understand.

This old gentleman is indeed an open-minded and studious person, but unfortunately he lacks sufficient knowledge after all.

"It doesn't matter if I don't understand, naturally someone understands." Shogishi put away the drawings with a smile and said, "What I learned today is really an eye-opener for me!" At the moment, I was so anxious that I just wanted to find someone to make this microscope...... Don't leave it at this today, don't blame you. ”

Of course Wu Xie didn't care, he could completely understand Jiang An's mood.

After a little explanation, Jiang An left the town and went to Wu'an County to find a craftsman to make a microscope, while Wu Xie left the pharmacy and came to the blacksmith shop.
