When Catherine was in the inner suite, she hurried out of her boudoir after changing into a light and decent shirt and trousers.

Many of the maids in the mansion quietly looked at the strange ones, and when Byron looked back, they immediately dodged.

Through the real-time monitoring of the [Golden Law], he heard their thoughts and what they had just said clearly:

"You see, the battle between His Excellency the Governor and the Count's Mademoiselle is a bit fierce."

"It's three hours, it's so powerful, is this the strength of a second-order powerhouse?"

“”

Byron had only just come ashore, and the two of them had been together for several hours.

The house was about to be demolished by them just now, and even Catherine had already changed her clothes, which inevitably made people think about it.

It's also to blame Catherine for placing all the well-educated valets on her hand who have even embarked on the path of transcendence to key positions up and down the territory.

Although the background of these local maids recruited temporarily is clean, the overall quality is quite average, and they are not worthy of the cultivation of a big noble family at all.

It is completely incomparable to the well-trained elite maids of the Old World.

Not to mention that there is no such thing at all, even if you see the dining room, living room, garden, and even the grape trellis with your own eyes, you can keep your eyes squinted and keep your mouth shut.

Don't think much about it, there will soon be a lace message on Tayman Island that starts with "Hey, have you heard" and "Pass it on".

Of course, it is much better for them to pass on this than to pass on the two or three things about the governor and the squid/octopus.

At least when the rumors spread, the pirates of the privateer fleet, and even the Newman family in the royal colony, would be happy to see it.

The main problem is that there is a lack of talent in the territory, and there is also a shortage of people.

But there will be soon, there will be undead acolytes, gods, nature spirits, and natives. ’

Neither of them paid attention to what the maid thought, and walked out of the simple wooden earl's mansion side by side.

After opening the access to the third-order Eagle Spirit Warrior Geronimo, the other party had already followed the guidance to the top of their heads.

"Mr. Byron, 100,000 is urgent, please hurry up and help."

The eagle swooped down from the sky with a whirlwind, and both its movements and shouts were visibly eager.

Jerónimo himself wasn't the only one who came.

On his broad back, three others jumped down in advance.

One is the highest-ranking great shaman in Chichen Itza, Iokotel, after the king and princess of Chichen Itza all died in the city of Azq.

In his hand, he still clutched the cane studded with the number eight crystal skull.

It was from him that Byron obtained the status of the superior nobles of the city-state, and agreed on the details of the joint army.

The other was a middle-aged female shaman she had never seen before, holding a black humanoid pottery in her arms.

In the urn was a teenager who looked to be only a teenager, with only half of his head exposed, and his eyes were closed, as if he had fallen into a deep sleep.

Seeing such a battle, Byron's heart suddenly moved:

"Here's your chance."

He has never been a merciful man, and he knows very well that the business of rushing is never easy to do.

Even if it's saving lives.

No matter how good your medical skills are, you can see the problem before the patient becomes ill, and if you take the initiative to come over, people may still suspect that you have ulterior motives.

After leaving the shores of Lake Texcoco, it took three days for the expeditionary force to cross the rainforest and another three days to return to the Taiman Islands.

For nearly a week, there was no response from the city of Chichen Itza.

It is conceivable that if it weren't for the sudden unexpected situation.

It is not so easy for them to send the eighth crystal skeleton [Quetzalcoatl] Kukulkan to the Taiman Islands, and fully cooperate with them unconditionally.

Just as he thought, Jerónimo, who had turned back into human form, hurriedly stepped forward to introduce Byron:

"Sir, this is the great shaman Sivatl of Uxmal, the city-state next door to Chichen Itza, and this time they were miserable by those Castilians."

Through his narration, Byron quickly figured out the cause and effect of the incident.

After the collapse of the Taya Empire, it was divided into more than 100 city-states, large and small, that were plagued by civil strife.

Each city-state has its own interests, and each wants to take the lead in recreating the empire's former glory.

If the Azk Empire had not been in the north before, they themselves might have been killed in a river of blood.

In the indigenous civilization, death is not the end, and the guardian spirit needs to be offered at all times.

It wasn't just the Azk Empire itself that started the Blood Sacrifice and the War of Glory.

The only city of Chichen Itza, which is dedicated to the Quetzalcoatl god Kukulkan, is one of the few city-states that does not offer blood sacrifices to the gods.

Today, Uxmal and Tayapan are the three major city-states of the Taya Empire, along with Chichen Itza (chapter 132).

The other two had similar experiences to Chichen Itza.

In exchange for peace, the beautiful princess and the king of their own family were lured to the royal city of Azk to attend the wedding of the previous emperor.

In the end, all of them became sacrifices with the royal city of Tenochtitlan as the core, condensing the "collective subconscious sea" of the Taíno people to create the [Golden Codex].

And the two of them are even more unlucky than Chichen Itza City.

Acting as a spearhead in the organization of the anti-Azik coalition.

A large number of warriors were sent to storm the city of Azq, along with the Kingdom of Castile, the agents of war, whom they had not paid much attention to at first.

This is a good thing, in the end, it was not only the princess and the king who accompanied them, but even a considerable part of the elite troops were almost buried by the [Funeral Beak Epidemic Doctor].

"Because the grotesque that spread the plague divided the infected areas according to distance, and the time of onset varied.

Most of the warriors who were too close to the plague aura had already fallen in the Azk King's City, but there were also a handful of people standing far away who did not have any symptoms.

One of the high-ranking warriors, who served as the royal guard, thought he was fine, but he suddenly fell ill shortly after returning to Uxmal City.

It also allowed the plague to spread among the people before the [Funeral Beak Plague Doctor] reached the city-state.

This is Prince Miktka, and the last heir to the royal family of the city-state after the death of the king and princess, so you see"

Byron took the words of the old man Geronimo in his heart:

Therefore, the tragic experience of the same kind became the last straw that overwhelmed the psychological defense line of the high-level of Chichen Itza City, and also dispelled their last layer of luck.

The psychological bottom line has dropped again and again, and the price you are willing to pay is far greater than before the disaster fell on your head.

As long as my medical expenses are not excessive, they should be able to accept them.

Bringing this lone seedling of Uxmal City over, in addition to the relationship of allies, may not be without the idea of a priori goods.

Still, it's exactly what I want.

Once there is a successful demonstration, my plan to use my strength to eat the last home and eat the next home can be officially launched. ’

Immediately, he opened the [Children of the Storm] and added a layer of spiritual protective clothing to himself, and nodded to them:

"We're all friends who fight side by side, so I'm naturally going to do my best.

Thankfully, you came early, and if I had come a few days late, I wouldn't have been able to save him.

Come with me. ”

Saying that, he took the lead and led a few confused people into the cattle pen on the island.

There are dozens of cows that Catherine bought in advance, all grazing leisurely.

The girl stepped forward and pushed aside the female workers who were milking, and said to Byron with her hands behind her back:

"As you say, I personally visited the cattle markets of Jamestown and the other surrounding colonies.

Each of the 'sick cows' found was completely in line with the symptoms described by Ling, but the degree was different. ”

For other things, she may instinctively think about the economy, and try to save every copper plate by all means.

But as a hopeless brother-in-law, even if he can no longer understand Byron's intentions, all the requirements for him will definitely be completed without discount.

Even the premium bidding will take all the "sick cows" that you see.

Byron opened the [Echoes of History] and looked at all the cows, and found that all the ** parts of these cows had local ulcers, or acne.

It's exactly what I remember.

Nodding with great satisfaction:

"It's done well, although some of them have healed on their own, but most of them are still in the stage of blisters and pustules, which is just convenient for extracting cowpox."

"Cowpox?"

Hearing this word that was so unfamiliar that it had never even appeared in this world, several people, including Catherine, couldn't help but be stunned.

"Aren't we going to treat smallpox in people? What does it have to do with cows? ”

Byron knows very well that at a time when phlebotomy is still prevalent, concepts such as interpersonal infectious diseases, vaccines, and the immune system are no less than Zenith-level knowledge.

For the follow-up plan, I can only explain to them the principle of my treatment in a concise way:

"We all know that if a person has had smallpox, he will not get it a second time after he has recovered.

That's because his body already produces a special substance that fights viruses, which I call antibodies.

In fact, if we take pus from a person with mild smallpox and infect ourselves, we can also gain immunity.

However, the risk of this method of human pox infection is extremely high.

Luckily, I stumbled upon the discovery that people infected with cowpox, or smallpox in cattle, can also get the same immunity.

The most important thing is that the symptoms are mild and not fatal"

A few people could hear him clearly.

"I see, it's a common use of poison to fight poison in black witchcraft."

The vaccinia virus is very weak in human pathogenicity and generally only multiplies at the site of inoculation.

However, because it has strong cross-immunity with smallpox virus, immunity to smallpox virus will also appear in the human body after vaccinia vaccination.

Only then can poison be fought with poison.

But after listening to his explanation, they have studied all kinds of black witchcraft, and the two shamans with the strongest receptive ability not only did not feel relaxed, but frowned even tighter.

In particular, the female great shaman Sivatel couldn't help frowning and asked:

"But Mikteka has been infected with the plague, and if this method of fighting poison with poison is adopted, by the time your cowpox takes effect, he will probably already be sick and dead."

Byron lifted the non-existent eyes on the bridge of his nose and smiled calmly at her:

That's a good question.

If you want to ask why you can treat patients with cowpox to smallpox, you have to mention the time difference between the onset of the two.

Because cowpox can attack faster than smallpox.

The body will have enough antibodies 10-14 days after vaccination, and the incubation period for smallpox is 12-14 days.

Therefore, vaccinia vaccination is given on the second day after accidental contact with the patient, and smallpox can be prevented.

Most of the patients do not get sick after 3-7 days, but they can reduce symptoms after 8-10 days, and they will be completely ineffective if they are vaccinated after 10 days.

Now it has only been 6 days since the birth of the [Bird's Beak Epidemic Doctor], and His Royal Highness the Prince is indirectly infected, so the time is completely in time. ”

"yes, that's great!"

Several of the top leaders of the indigenous city-states suddenly turned their worries to joy.

Now, the theory is complete, only the practice is needed.

If the treatment is successful, it will not be a problem for Byron to be crowned the "father of immunology" by virtue of this merit alone.

"No, there are no ifs.

Just like the invention of the 'Tudor Mixed Sailboat', a major contribution that directly changed history, you don't need to wait for the legend to ferment, and you can directly get the title effect.

There is no vaccine inventor in this world, and now I am the veritable father of immunology!

Plagiarism? Can this healer's benevolent thing be called stealing? ”
