The physiological structure of the human body in this world is more than 99% similar to that of human beings on earth, and the medical system is also very similar, but some elements and drug extracts are different from those of the earth.

Qin Lun himself studied a complete set of clinical medicine in Handan Prison, and at the beginning of entering the world, he compared several basic medical books obtained by Tong Guò Stan Xiaolou, and he was definitely a qualified doctor in terms of medical theory.

From his first exposure to the epidemic virus on the hunchbacked servant Frank to the operation of Morrison in the town square, Qin Lun collected some epidemic viruses. Since Stan's small building had burned down, Qin Lun didn't have a suitable test vessel, but that didn't prevent him from conducting some simple experiments.

Through these experiments, Qin Lun confirmed two speculations. The first guess is that this epidemic virus is a living microorganism with extremely phagocytosis, and it can be said that it is a cancer cell that has strengthened hundreds of times more power for humans in this world.

The second guess is that although it is difficult for this epidemic virus to coexist with other biological cells, it is not completely impossible to neutralize. Qin Luntong guò had the "World Tree Flower Dew" at hand, and came to a conclusion that if the nature of the "World Tree Flower Dew" is "life", the attribute of the epidemic virus is "death".

This is also the reason why the "World Tree Flower Dew" is able to repel the epidemic virus, life and death are incompatible opposing attributes. However, Qin Lun discovered by accident that these two attributes could reach a state of equilibrium under certain circumstances.

It was a few days after Qin Lun had cured Morrison, and at that time, Albert Castle had not yet come to invite him, and the small town of Odia was full of plague patients. Among these epidemic patients, Qin Lun found that one of them, a lactating young woman who had just given birth, had not died after a week of illness.

After examining the young woman, Qin Lun found that the reason why she did not die was very simple, the young woman's milk contained a high degree of life essence, which offset the "death" attribute of the epidemic virus and delayed the onset of the disease.

This unexpected discovery made Qin Lun's eyes light up. He uses breast milk as a base and blending agent, adding a small amount of diluted "World Tree Flower Dew" to the epidemic virus. Through several trials, he obtained a "nutrient solution" with a shelf life of only about three or four days. This nutrient solution can delay the onset of the epidemic and prolong the life of the patient by about a week.

Qin Lun spent two drops of "World Tree Flower Dew" for this experiment, and it seemed that he was willing to give up his roots. You must know that he saved Frank and Morrison, and only used two drops of "World Tree Dew".

In fact, Qin Lun just wanted to get this weakened version of the "nutrient solution". He had already vaguely guessed that the epidemic was related to the Albert family, and the show was to get the invitation of the Albert family, and he wanted to go to Albert Castle, not to save people, but to explore and complete the mission of the other world.

The nutrient solution can only prolong the patient's life, not completely cure it, so that he can stay in the castle for more time.

When Qin Lun saw Miller, he realized that he had made a mistake and made the breast milk nutrient solution the best medicine for the little guy. The disease in Miller's body and the immune system were balanced, however, due to years of coma and bedridden, his physical condition was extremely unoptimistic.

The nutrient solution is not a cure for diseases, but it is a super nutrient added to the "World Tree Flower Dew", which is extremely beneficial for improving the health of Miller. Qin Lun's only concern was whether the nutrient solution in a balanced state would have the opposite effect if it touched a millet in a balanced state. You know, the nutrient solution also contains epidemic viruses.

Fortunately, Qin Lun's gambling was successful! Miller's body was nourished by the nutrient solution, and the diluted World Tree Lotion was mediated by breast milk, and there was no more violent conflict with the epidemic virus in the little one's body.

Qin Lun's mind was full of thoughts, and he gave an ambiguous answer to the old baron's question.

"For the time being, I still need to observe for a few days, if my medicine really has an effect on Young Master Miller's health, then when his body functions recover, it may be possible that he will wake up!" Qin Lun picked up the teacup again and said slowly, "However, this elixir is very precious, and the blending process is very complicated, and some of the ingredients need to be purchased from Odia Town......

"Bonie, ask Jason to fetch all the medicines in the castle and let Dr. Stan see if there are any suitable ingredients!" The old baron and his family looked at each other, and a smile appeared in their eyes. The medicine Qin Lun said was precious and complicated to blend, so in their opinion, they were naturally asking for compensation.

But it's also a matter of course! If this young doctor was able to solve the epidemic that even the imperial physician could not do to save Odia and Miller, how could the Albert family be stingy with a little money.

"I've heard that Dr. Stan doesn't have a formal license to practice medicine. For a skilled doctor like you, this is simply an insult. When this incident is successfully resolved, the Albert family is willing to vouch for you! The old baron solemnly promised.

Qin Lun smiled and said nothing, he didn't need any medical license, as long as he could continue to stay in Albert Castle, he had already achieved his goal.

A moment later, the old butler Jason brought a basket of medicines and reagents. Qin Lun flipped through these reagent bottles casually, he knew that these things were useless to him, breast milk was not medicine, and the "World Tree Flower Dew" was not a thing of this world. However, he has run out of anesthetics and antibiotics, and it is not bad to add some here.

Suddenly, Qin Lun's hand stiffened, looking at a small reagent bottle, his pupils shrank. The reagent bottle is engraved with the letters "J・R", and if you look closely, there are also reagent bottles with letters such as "H.C" and "Y.P." on them.

Looking at these reagent bottles marked with capital letters, Qin Lun's eyes flickered. Perhaps the Albert family thought that the letters were the names of the drugs, but he understood that the letters that looked like the names of the drugs were not the names of the drugs.

Because, in his medicine box, there are also several unique reagent bottles marked with capital letters, such as: the breast milk nutrient solution. These drugs are not labeled with their names, and only the doctor who owns them knows what they are. These drugs are all special drugs prepared by doctors and private individuals in this era.

Qin Lun's reagent bottle of nutrient solution was marked with "S・T", which was not the name of the drug, and the surname Stan was capitalized. The doctors of the Stan family identify these drugs not by their names, but by the color of the bottles.

The medicines in this basket are not what the castle has stockpiled, and the personal medicines of some doctors, the doctors who died in Albert's castle!

Touching these cold reagent bottles, the pores on the back of Qin Lun's hand stood upright, and he picked up a few bottles of ordinary anesthetics and antibiotics, and he waved his hand to the old butler and took away the medicine basket.

"I don't have what I want here, I'll have my entourage Frank go to a few nearby towns to buy them!" Qin Lun got up from his chair and walked towards the door, "In the next few days, I will stay and observe Young Master Miller's physical condition, and I will disturb you!" ”

"You're welcome, Dr. Stan! It is an honor for the Albert family to be treated by Miller! The old baron stood up with his two sons and daughters and thanked Qin Lun, while the old housekeeper next to him immediately handed Qin Lun a silk cloth bag.

"Whew!" Qin Lun threw the silk sac in his hand, the corners of his mouth turned up slightly, and walked side by side with Frank in the courtyard of the castle. The silk sac was full of gold coins, which the Albert family paid him for the purchase of materials, and of course for his milky medicine.

"Frank, what's going on with what I've asked you to inquire about?" Qin Lun glanced around and asked softly.

"Master Wellington, that matter is not a secret to the servants of the castle, I already know the general direction, but I still need to see it on the spot!" Frank scratched his head and said angrily.

"Hmmm! Remember, in addition to the things I asked you to buy in town, wait for me in the early hours of the fourth day across the stone bridge from the castle, and hide it so that no one else can see it! Qin Lun threw the entire bag of gold coins to Frank and instructed softly.

"Less...... Master, don't have so much! Frank's hand shook and he almost threw the money bag away.

"It's all for you, and you'll be the steward of the Stan family from now on!" Qin Lun grinned, what was the use of the gold coins in this world, he always wanted to return to the shattered starry sky. It's better to leave it all to Frank and just fulfill the previous promise. Let this loyal servant have a source of livelihood after he leaves, which should be Frank's salary during this time.

Frank was silent, but solemnly put away his purse, walked out of the castle without looking back, and disappeared at the end of the mountain road.

……

"Dr. Stan, it's so early for a walk!"

"yes, Jason, get used to it!" Qin Lun jogged across the stone bridge and waved his hand to the old housekeeper and tailor in the courtyard with a smile.

In the past few days, Qin Lun's life in the castle has been uneventful, observing Miller's health for a while every day and chatting with several members of the Albert family.

It's just that every evening after that, the young doctor stays in his room all night, and tells the old butler Jason not to let anyone disturb him, that's when he mixes potions. In the early morning, the young doctor would run out of the castle and walk outside for half an hour before returning.

After two or three days, the whole castle knew about his habit. However, there is nothing to be curious about, as the evening is quieter and allows the doctor to concentrate on the medicine, and the morning run is the most normal.

In the middle of the night of the third day after the hunchbacked servant left, an hour or so before the morning to be exact, a figure opened the small gate in the city gate, ran out of the castle, and disappeared into the darkness along the stone bridge......
