Yang Hanyi is good at gynecology, and doesn't know much about smallpox, or even this "human smallpox technique".

Zhu Youxiao didn't get to the point. He talked about antibodies and immunity, which made Yang Hanyi confused and seemed to understand but not quite.

Instead, Tao Yan hit the nail on the head: those who recovered from smallpox were indeed immune for life. This was quite unique and easier for people to understand.

Yang Hanyi understood a little, but was still not completely reassured.

"After meeting Fu Jiasheng, I'll make my own plans." Zhu Youxiao didn't completely trust the "smallpox test" and always wanted to inquire thoroughly before making a final decision. He politely expressed his caution and changed the subject, asking, "By the way, I sent someone to give Mr. Yang the microscope. You can use it frequently. It will definitely benefit medical theory."

Uncovering the microscopic world can explain many causes of disease and will naturally be of great help in improving treatment methods.

Without theory, it will be difficult for medicine to develop and medical skills to improve. Empirical treatment methods will ultimately have great limitations.

For example, why drinking raw water can easily cause illness, and why good hygiene habits such as frequent hand washing can prevent diseases.

Only when you see the microorganisms that are invisible to the naked eye will you understand the reasons, instead of relying on guesses based on the five elements.

"I am deeply shocked," Yang Hanyi said, bowing. "I never imagined such a microorganism could exist. Perhaps the cause of illness is these invisible little creatures. I will study this diligently, hoping to improve my medical skills."

Zhu Youxiao nodded and said, "I am very pleased that Mr. Yang has such a keen interest in learning and progress. The clinic is a bit stingy, so let's turn it into a women's medical school. I will first allocate 100,000 yuan and find one or two more large mansions in the capital."

"Your Majesty, I thank you for your great grace." Yang Hanyi stood up and bowed to express his gratitude.

There was nothing else to do, so Yang Hanyi took the opportunity to leave. Tao Yan picked up the cat basket and followed her master.

This girl is very smart and her comprehension seems to be higher than that of her master. If she concentrates on medicine, she will achieve great things in the future.

Zhu Youxiao looked at the girl's small back carrying the basket and shook his head slightly, thinking that giving the girl a carrying basket would save more effort.

If medicine could be improved, it would not only benefit the general public, but also provide more protection for himself and his family. Especially for the little ones, growing up healthily and enjoying life happily was perhaps what Zhu Youxiao looked forward to most.

The premise of all this is that the world is peaceful and there is no war. As for famine, Zhu Youxiao cannot control the will of heaven, but he is trying every means to reduce its impact.

Ultimately, the Liaodong Jiannu were Zhu Youxiao's biggest concern, even though most people did not consider the Jurchens, whose population was less than one million, to be the biggest threat.

But everyone could see the emperor's concern and urgency about the Liaodong war. This was obvious from the money and materials invested and the degree and frequency of his personal inquiries.

Yang Hanyi came suddenly, and although it took up some time, it did not affect Zhu Youxiao's planned summons.

First, martial arts professors Sun Yuanhua, Mao Yuanyi, Lu Jishan and others were summoned to the emperor to report to him on the assignment of martial arts students, and to distribute booklets such as "Records of Practical Combat for Musketeers" and "Examples of Practical Combat for Artillery" to various military towns.

If the Ming army wants to become stronger and stronger, it is crucial to strengthen communication, speed up the transmission of information, and conduct research and analysis.

The emperor undoubtedly attached great importance to this aspect and required each unit to submit detailed reports on every battle. Whether it was a great victory or a defeat, a battle report had to be written truthfully, and he would even send a special person to report back.

The result was that the Ming troops in other military towns were able to gain experience or learn lessons without actual combat, and were better able to grasp the enemy's combat patterns and new tactics.

For example, the battle between the three alliances in southern Liaoning and the two flags fully demonstrated the importance of infantry battle formations using bayonets to resist the impact of enemy cavalry, occupy favorable terrain, and maintain a strict battle formation.

For example, the encirclement and annihilation of Amin's troops proved the huge damage that flintlock rifles in linear formations could cause to the enemy, as well as the advantages of cavalry wall-like charges.

Every success has its flaws and shortcomings. The Ministry of Martial Arts and the Ministry of War would carefully analyze and study each battle and submit a report to the emperor.

Zhu Youxiao would then provide further confirmation or guidance based on his own experience in military theory. Finally, a booklet-like record of battle cases was compiled and distributed to various military garrisons for study.

This set of procedures of post-war summary, reporting, analysis and research, drawing conclusions, and then distributing them to various military towns for study enabled the Ming army to continuously improve its combat effectiveness.

Weapons and equipment more suitable for battlefield use will also be manufactured or deployed at a rapid pace, such as hand-thrown bombs, vehicle-mounted falconets that can quickly replace sub-guns and fire shotgun shells, and Ming fortresses that can long-rangely bombard enemy commanders...

In the report of the martial arts professor, Zhu Youxiao learned about the production and manufacturing of weapons and equipment, the training and deployment of artillery officers, and the distribution of guiding teaching materials to various military towns, all of which were satisfactory.

Zhu Youxiao was pleased that the huge sums of money were not wasted. If spending money could accumulate victory, he would not be stingy, even if it meant turning the magnificent palace into a shabby place.

If the skin is gone, where will the hair be attached? If the country is destroyed, will the imperial palace be left to the Jiannu? If the Ming Dynasty is about to disappear, what use will those princes and nobles have for it?

Zhu Youxiao's determination meant that he was already halfway to achieving victory in pacifying the Liao and exterminating the slavery. Considering what Li Zicheng had plundered in the capital, would Zhu Youxiao still be polite when the time came to risk his life?

Of course, now that the hope of success is within reach, Zhu Youxiao can be patient for a while. But the days of the powerful and wealthy vassal states will definitely not be easy. Even if the Liao Dynasty is pacified, what about the famine?

Zhu Youxiao was very satisfied with the report on martial arts. After comforting them, he let them leave.

The Liaodong War has reached this point. There is no need to climb the technology tree in military industry and develop more powerful weapons and equipment.

The Ming army's current equipment level was among the best in the world. Flintlock rifles plus bayonets, field artillery plus wall-mounted cavalry, put it ahead of any other country's army.

Therefore, if weapons and equipment are used well, food and wages are supplied adequately, and military morale is boosted sufficiently, victory in the war is only a matter of time.

Sun Yuanhua and others had just taken their leave when the generals of the Beijing camp, who had been waiting for a long time, were summoned to meet them.

Among them are not only the flying cavalry generals who will rush to Liaodong in the autumn, but also the generals who will lead the teaching teams to various military towns to train troops.

Similarly, the training of the Beijing Camp Flying Cavalry has also drawn on the combat experience of the naturalized cavalry, and adjustments are being made to the formation and charge speed.

Furthermore, to compensate for the shortcomings of actual combat, the Flying Cavalry also conducted confrontational drills. Casualties were inevitable in the process, but the generals considered it well worth it.
