Tuberculosis was the conclusion that Zhou Changfeng had come up with after a long morning, and he needed a disease that could be cured, but the course of treatment was relatively long, and it was not suitable to show his head and work normally during this time.

After pondering for a while, it seems that only tuberculosis is the most suitable right now?

Tuberculosis is arguably one of the oldest infectious diseases in history, and archaeological discoveries have been found in humans since the Neolithic Age, 10,000 years ago.

This is a chronic respiratory infectious disease caused by Mycobacterium tuberculosis invading the human lungs and seriously endangering health. However, for a long time, tuberculosis was not particularly prevalent.

It wasn't until the beginning of the eighteenth century that the nightmare of tuberculosis officially broke out, and Western literature of that period often contained descriptions of "pale, emaciated, and violent coughing ......".

What makes people laugh and cry is that many European aristocrats at that time were "proud" of being infected with tuberculosis, because this would make them pale, which was in line with the strange aesthetics of the time.

Around the same time, this evil disease was also rampant in China. The ancients originally classified it as tuberculosis, but in the later Ming Dynasty, some doctors officially named it tuberculosis.

For a long time, tuberculosis was an incurable and terminal disease, and people could only be treated conservatively by exercising and resting in a place with clean air.

At that time, tuberculosis sanatoriums were almost everywhere, but they only maintained the survival of some tuberculosis patients for about ten years.

Although in 7882, the German physician Robert Koch successfully isolated the tuberculosis bacillus and found out the culprit, but people have not been able to find a drug that can deal with this stubborn bacterium for decades.

The French were the first to come up with a vaccine, the famous BCG, but this only provides prevention for children and will become ineffective as they get older.

Zhou Changfeng remembers that in his original plane, it was only after the end of the war that the Americans discovered streptomycin, and people had effective drugs for tuberculosis.

However, what is interesting now is that in the twenty-sixth year of Zhichang, there was a county king in the Later Ming Dynasty who was also infected with tuberculosis, and the county king was very unwilling, so he desperately searched for all kinds of strange things to eat. Superstitious in the principle of fighting poison with poison, he tried many things, such as scorpion venom, snake venom, and bee venom, and then began to experiment with all kinds of chemical poisons.

Of course, it didn't work, but tossed himself half to death.

Eventually, one day, he had the whimsical idea that only a poison that "could poison livestock, but not the human body" could cure tuberculosis.

So he began to experiment with dogs, frantically searching, and the hard work paid off, and the attendants of the county king's mansion really found a medicine that could quickly poison the dog, but it was basically harmless to the human body, and the overjoyed county king really took effect after taking it.

The medicine they found by mistake at that time was actually isoniazid, the first-line drug for the treatment of tuberculosis in later generations.

In fact, isoniazid was synthesized as early as 7912, and was originally synthesized by two graduate students at Charles University in Germany, intending to use it as an antidepressant.

However, because of some liver and kidney toxicity, it has not been promoted, and unfortunately people have not found that it has a miraculous effect in the treatment of tuberculosis.

In ancient times, Shennong tasted a hundred herbs, and now there is Zhu Wangye who tried a thousand poisons, and interesting things are interesting things, but this completely reversed the situation of "ten tuberculosis and nine deaths", and tuberculosis is no longer a terminal disease.

However, because the king of the county had tried too many poisons before, although he was cured of tuberculosis, he did not live long, and he died a few years ago.

“…… So, doctor, I need your help. ”

After listening to Zhou Changfeng's statement and explanation, the doctor took off his glasses and nodded seriously, "God bless you, sir." ”

He got up and left, went to the next office, and talked to the other doctors.

After a while, he came back with an X-ray film.

"This is a chest x-ray for a patient with moderate tuberculosis, which usually takes 10 to 14 months of treatment and recuperation, and you know, it's a very stubborn disease," the doctor said. A year should be enough time for you. ”

After getting the fake medical certificate, Zhou Changfeng did not stay for long, and returned directly to the hotel where he stayed.

Now it was Chen Guangyun and Adara's turn to be surprised.

"Huh? Tuberculosis? It shouldn't be, you look so good, and you don't cough, why did you get that thing? ”

Chen Guangyun, who looked suspicious, picked up the film, walked to the balcony and looked at the sun, and was immediately startled by those conspicuous nodules.

"Sir, then you can't stay here for long, you have to find a place to recuperate and take medicine." Adara worried.

Despite the availability of a cure, the fear of tuberculosis has not completely dissipated.

Zhou Changfeng behaved calmly, and he said while packing his bags: "Chen Guangyun, you go back to Barcelona directly, I have to go... Paris. ”

"Paris? What? Chen Guangyun felt inexplicable.

If the condition is serious, then why not just return to China?

If it's not serious, then go to Barcelona to recuperate for a few months before continuing the mission.

"The doctor said that my situation is a bit special, that medical conditions in Spain are limited, and that it is better to go to England or France."

"Then why don't you go back to Daming? Yingtian's hospital can treat this as well. ”

"How troublesome it is to return to China, the flights are gone now, and I have to go to Paris to have an international flight to Yingtian, in that case, I might as well be in Paris for the first half of the year, and it is convenient to come back when there is nothing to do."

"Uh... Also. ”

The current situation is very suitable for Zhou Changfeng to carry out his ideas, because the entire Iberian Peninsula is in chaos, and the army is in chaos.

The more chaotic it is, the easier it is to hide people's eyes.

For the time being, it is difficult to get in touch with the headquarters of the Ming military expedition, and can only go to the post and telecommunications bureau to send telegrams, and the limitations of communication means in this era are still very great.

Chen Guangyun didn't know that everyone had been fooled, so he was quite worried about Zhou Changfeng's condition, so he didn't think much about it, and asked him to go to Paris for treatment as soon as possible, while he returned to Barcelona.

"When you get there, remember to say hello to the Ming Legation."

"Of course." Zhou Changfeng agreed very simply.

Because they seemed to be in a hurry, they did not stop at Qinqiong for long, and after waiting for the Ming military expedition's left-behind personnel in Barcelona to reply to the telegram, the three of them immediately set off again.

When they arrived in Tarancon, Adara parted ways with the two, and Chen Guangyun and Zhou Changfeng took the train to their respective destinations.

The train clattered and finally stopped at Manresa. After that, Zhou Changfeng hired a car and finally arrived in Pucciceda, a small town on the border between Spain and France.

The border has been blocked, and the border checkpoints are filled with heavily armed French soldiers, and everyone who crosses the border is subject to strict checks.

However, with the help of the medical certificate and Daming's passport, the border prosecutor who looked very amiable did not embarrass Zhou Changfeng, and knocked down the stamp of permission to cross the border with a click.

Standing on French soil, Zhou Changfeng glanced back in the direction of Spain and took a deep breath.
