Jie Minghuan's stay did not bring any changes to the people in the inn. This master of martial arts seems to be unfamous, or the people here are ignorant. In short, everyone only regards him as a man who is so down-and-out that he needs to sell his horse, and does not regard him as a master at all.

Time flies, and in a blink of an eye, Wu Jie and Taotu have lived in Qingniu Town for half a month.

In the past half a month, they visited Qingniu Town and the nearby mountains and forests, became familiar with the more special people in this town, and also met other immortal seekers.

It is indeed a bit supernatural in Qingniu Town, so there are not many people here to seek immortality. In addition to the eight people living in the inn, some people rented or bought houses of residents in the town. As for the young master Wei Teng and Wei who had disdained to say that he didn't want the idle people to disturb him, although he still lives on the third floor of the inn, his craftsmen have already decorated a yard he bought not long ago and will probably move out soon.

The immortal seekers in the town come from all directions, the farthest from Gu Yuan, the Great Qin Kingdom in the northwest of Jiuzhou. This young man, who was only 25 years old, has been trekking on the road to seek immortality for ten years. His situation is similar to Wu Jie. He was determined to seek immortality after meeting an immortal by chance. However, he is not as lucky as Wu Jie, and has not gained anything yet.

Among the seekers of immortality, there are many rich children. In addition to Wei Teng and Taotu, there is also Liu Ming from Yuancheng, the capital of the Great Yue Kingdom. The Liu family has been doing business for generations and is a famous wealthy businessman in Yue Kingdom. He is truly rich. However, this young master Liu is very friendly and does not have the arrogance of Wei Teng and is easy to get along with.

Of course, Liu Ming did not go out alone to seek immortality. He had three followers around him. One was a book boy who served him since childhood, the other was a guide who was familiar with the customs and customs of various places, and the other was a martial arts master.

The martial arts master was very skilled. The day after Jie Minghuan moved in, the two of them had a disagreement, and it was hard to tell the difference. However, Wu Jie noticed that Jie Minghuan did not use the Duanyun Sword Sword, which was the treasure of the Nine Sword Sect. I think with the arrogance of this master, he probably disdained to use the magic sword to win in a single battle that was only tentative.

The battle was extremely fierce, which made the people who looked down on Jie Minghuan, a down-and-out martial artist, change their qualities. In the next few days, more than one person went to make friends with him deliberately, but they were all defeated. Jie Minghuan let the masters of the world not do anything, and he was determined to seek immortals and asked, how could he waste time making friends with these people he looked down upon?

Among the seekers of immortality, there are also some people with strange personalities. For example, there is a young master Yi who has lived in Qingniu Town for more than a year. He goes up the mountain to chop wood every day and lives a poor life with the little money earned from his labor. But he often buys pens, ink, paper and inkstones, and the ones he buys are high-end goods. It can be seen that his wealth is quite rich, but he doesn't know why he has to live a hard life.

In addition to these seekers of immortality, there are also many residents in the town who are worth mentioning.

The first thing worth noting is of course the inn owner named Li Xiaoyao, who named his son "Li Xiaoyao". This uncle, who is nearly forty, has a kind round face and a slightly fat figure, has a broad view and experience. He is the first person in the town to be well-informed.

Including Wu Jie, almost every seeker of immortality asked this uncle who had a similar name to a certain snack and had also obtained a lot of information that seemed to be quite reliable.

But for some reason, the information provided by this uncle with extensive knowledge was almost all of the "Immortals once appeared in a certain mountain". The seekers of immortals ran around because they heard his news, and they didn't know how much hardship they suffered.

It is the end of the first lunar month, and the coldest time of the year. Even the poisonous insects in the Great Yue Kingdom are mostly dormant, otherwise someone would have been bitten or even poisoned to death.

But strangely, no one revenges for him. On the contrary, everyone was still tirelessly following the suspicious news he provided to go to the deep mountains and forests to suffer.

"... Yesterday, Boss Li said he was drunk and said that there was a monster Iron-billed eagle on the Eagle Beak Cliff more than ten years ago, and it was later killed by the immortal." While tidying up his luggage, Tao Tu explained to Wu, "Brother Liu and I plan to go over and take a look. Even if we can't find the immortal, we may see some traces of the original. Mr. Wu, are you going?"

Wu Jie smiled and declined, left the inn alone and came to the pharmacy.

Compared with Li Honton, the pharmacy owner Jiang An seemed simple but much more high-profile. This name reminded Wu Jie that in a zombie film he had watched before traveling through time, the old man in BOS was nearly 60 years old, but he looked just a handsome middle-aged man in his thirties. He really had the ability to maintain his health and keep his face in a good way!

Because of this, many seekers of immortals insist that he is a master who is successful in practicing Taoism, and constantly pesters him for advice and recruits disciples, which makes him untidy.

But Dr. Jiang is worthy of being a human being who has lived for 60 years. It is much more difficult to ask something valuable from him than Li Hounting!

Everyone who tries to cliché him will find that he clearly wants to ask something, but after a few words, the topic is unconsciously brought to an aspect that has nothing to do with seeking immortality. Sometimes it is about body care, sometimes it is about the style of the Southern Manchus, and sometimes it is about the interesting stories of Xinglin...

If this man's words were really powerful, he would not be able to tell the other party, so he would simply leave his old face and rumor the words of the Golden Knife Man - the old man who was born in the south was incredible. Except for the tribe members in the deep mountains, those who could understand his native language would probably be able to count with one hand.

Wu Jie was the only exception because he never asked the doctor about seeking immortality, he only talked to the other party about medical skills.

Both sides are doctors. Jiang Yansheng has many years of experience in medical practice. Wu Jiesheng has the knowledge of earth medicine that is several levels ahead of this world. The things they are good at complement each other. Every time they discuss, they feel that they are quite rewarding.

Through discussion, Wu Jie learned many unique tips of the barbarians in the southern part of Yue, including some exclusive secret recipes with extraordinary medicinal effects, which are hard to exchange for.

But the gains from the shore are even more precious - no matter how precious these secret recipes are, they are still circulated among various tribes. As long as you spend enough money and time, you can always find them. However, the knowledge in Wu Jie's heart is truly exclusive. Unless there are other time travelers in this world, no one can understand it.

These days, the only thing that the doctor, who was harassed by the seekers of immortality, felt so much that he was comforted by the doctor was to learn the knowledge that made him suddenly enlightened and opened the door to advanced medical skills for himself.

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

"My friend, the 'bacteria theory' you mentioned really opened my eyes!" He said excitedly, "I thought about it carefully all night yesterday. Combined with many past experiences, the more I thought about it, the more I felt that what you said made sense!"

Wu Jie was not surprised at all. Since the basic physical and chemical phenomena in this world are still consistent with the earth, science in the general sense is naturally consistent in this world.

Perhaps the two worlds are different in some more in-depth and critical places, but at least things such as "bacterial infection" should not be wrong.

What's more, when Nanping County was disaster relief, "isolation", "disinfection", "sterilization" and other methods have been proven to be effective. Since those methods are effective, the bacteria theory should of course be valid.

However, his face was calm, but he muttered in his heart.

How could this doctor... accept new theories so easily? Shouldn't an elderly person of this age be a little stubborn?

"My friend, but I also have a question." Jiang An said again, "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 invisible to the naked eye in this world - you call bacteria, they are the culprits that bring many patients, especially diarrhea and ulceration. So can you find a way to find them?"

"What's the difficulty?" Wu Jie smiled slightly, asked him for the four treasures of the study, and drew a slightly prototype microscope on the paper.

There are roughly three keys in microscope technology: the first is the lens, the second is the base light, and the third is the lens barrel. After solving these three keys, the rest are details such as focus. In Wu Jie's view, although the technological level of this world is behind, at least in terms of technology, it will not lose to the Earthlings on the Ming Dynasty. The earliest microscope seems to be invented in the Ming Dynasty, so this world should be able to do it.

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

"Look at the old man, this thing can enlarge the appearance of a subtle thing twice, so that things that cannot be seen clearly by the naked eye can be seen... However, this thing is easier said than done. If it is not a master who is proficient in this art, I am afraid it will not be done."

After taking the drawings, he looked carefully for a while, and asked questions such as "why can it be enlarged". Wu Jie did not hide his own personal information and explained the principle of the lens to him.

"It's a pity that the climate here is hot, and it won't freeze even in winter. Otherwise, I could use ice to grind a lens for a live demonstration..." At the end of his speech, he sighed helplessly when he saw that Jiang An still understood.

This old man is indeed a humble and studious person, but unfortunately, he lacks enough knowledge after all.

"It doesn't matter if I don't understand, naturally someone understands it." Jiang An smiled and put away the drawings and said, "What I learned today is really an eye-opener! At this moment, I was anxious and just wanted to find someone to make this microscope... Let's leave this today, please don't blame me."

Of course Wu Jie wouldn't care, he could fully understand Jiang Yan's mood.

After giving a brief explanation to the An, he left the town and went to Wu'an County to find craftsmen to make microscopes, while Wu Jie left the pharmacy and came to the blacksmith shop.
