China has a vast territory and a variety of landforms, which leads to huge differences in the living environment. Some places are like spring in all seasons, some places are warm and humid, and some places are cold and freezing, dry and rainy. All of these are difficult to compare!

A person travels thousands of miles apart because he is not adapted to the new living environment and is very likely to get sick. In the mild case, he may feel nausea, vomiting, and diarrhea; in the severe case, he may not subside, and he may even die. This is what people often say is not adapting to the local environment.

Fortunately, the Chinese ancestors were very smart and came up with many solutions. For example, Zhuge Liang during the Three Kingdoms period invented a drug "March Sol" that was effective in treating the local environment and the local environment!

The Shu army fought south and north, but the soldiers rarely got sick, which was due to this drug.

Medical Saint Li Shizhen obtained the secret recipe of "March Jun San". After careful research, it improved it to make the medicinal properties more mild and easier to configure, and it was recorded in "Binhu Pulse Science"!

Although Xue Yu did not learn medical skills, he memorized the prescriptions in "Binhu Pulse Science".

"Please give me a pen, ink, paper and inkstone!"

"Come here, prepare pen, ink, paper and inkstone for Xiaoyou Xue!"

"Brother Yan, help!"

"Good!"

Xue Yu wrote oral, Li Yan wrote the original version of the recipe for "March Slave".

In addition, there is a formula of "snow cream" that can prevent frostbite. The weather in Liaodong is cold, and frostbite has always been a big problem.

One of the reasons for the defeat of the Ming army in the Battle of Sarhu was that the troops and horses drawn from all over the country were not adapted to the cold weather in the Northeast, and their hands were covered with bloody holes, and they could not even wield swords and guns. How could they fight with the Jurchen cavalry?

The Jurchens have lived in the white mountains and black waters for generations. Not only are they extremely resistant to cold, but they also have various ways to keep warm!

A formula of "Wuji Paste" is specially used to treat athlete's foot. When the army travels for a long distance, soldiers are prone to athlete's foot, which is painful and itchy, and itchy, which will affect the battle!

…………

Xue Yu memorized more than a dozen secret recipes, all involved from top to bottom, from inside to outside. As long as these drugs are configured well, they can basically solve the problem of not adapting to the local environment.

The next one is the weapon issue.

Xue Yu has browsed many military websites and read countless military novels. He dare not say that he is a military strategist (theoretical), and he is also a military fan of the ashes!

I do know a lot of ways to restrain cavalry, some of which are very domineering and cruel!

But, considering the current situation, we can only choose a few simple, practical, and quick-made weapons.

It was still Xue Yu's oral description, and Li Yan was responsible for the description, and he drew several weapons graphics in succession:

White rod hook sickle spear - the total length is 12 feet, choose solid ash as the rod, and install triangular steel spear head, one side is equipped with a curved hook with a blade, and the other side is equipped with a hard iron ring, which weighs seven or eight kilograms!

As early as the Qin and Han dynasties, some people came up with a way to make the infantry be arranged neatly, wear heavy armor, and hold long spears to fight the cavalry charge, and the effect was good!

Compared with traditional spear tips, this pyramid has a stronger penetration power, and it will be a blood hole when pierced. It is extremely difficult to suture it. The injured person will soon lose too much blood and die!

The sharp hook on one side is specially used for hooking horse legs. As soon as the war horse falls, the cavalry loses its power. The ability to fight in close combat is not as good as that of infantry!

The iron ring on the other side is used for hitting and is specifically targeted at the thick cotton armor of the Jurchens!

Wet the picked cotton, pat it repeatedly to make a very thin cotton piece, then tie multiple cotton pieces into a very thick cotton cloth, place iron armor between the two layers of cotton cloth, and fix it with copper nails inside and outside, and a pair of cotton armor is made!

Cotton armor is easy to make, low-priced, and has excellent warmth and defensive effects. It is very suitable for use in the cold Liaodong area, so it has become the standard armor for the Eight Banners soldiers!

But, cotton armor can withstand swords, bows, arrows, and even firearms, but it is powerless to do anything against dull weapons!

He swung the white spear and smashed it hard on the cotton armor with the heavy iron ring on it. He would not see any blood, but it could break the bones and tendons of the Eight Banners soldiers and break all the internal organs!

...

Kaltrops - there are four spikes extending, about a few inches long. No matter how you throw them out, one of the feet is always facing upwards!

This kind of thing is not very useful to people, because people can walk on the ground and kick the caltrop away, but the war horses don’t have the ability to do this. As long as they are stabbed, they will not be able to gallop!

As long as you are scattered in front of the military formation, you can effectively stop the cavalry from charging!

The three-foot-long iron pipe is equipped with a rotating handle and a spiral pointed tip below. Two soldiers cooperate, one is responsible for supporting, and the other is shaking the rotating handle. A few strokes are used to make a small trapped horse hole!

As long as the horse's hooves step in, they will immediately twist them into twists. The knight on the horse's back will not fall and break his bones and tendons, and will also vomit blood and lose his combat effectiveness!

...

Xue Yu and Li Yan cooperated with each other and quickly drew seven or eight kinds of weapons graphics, and clearly marked the size, so that the craftsmen could easily create it after seeing it.

"Xue Xiaoyou is so smart. With these weapons, it's enough for the Jurchens to drink a pot!"

"The weapon designed by my friend is really not ordinary vicious and vicious. I get goosebumps when I see it!"

"My friend Xue, are you a doctor who treats diseases and saves people, or have you been a butcher before?"

...

Qin Liangyu and the generals and officers were all people who had been on the battlefield for a long time. Naturally, they knew the value of these weapons and all showed ecstasy. They had to look at each picture carefully more than ten times, for fear of missing something!

When dealing with Xue Yu, he first praised him loudly, then whispered, and finally stopped talking, his eyes full of fear and fear!

I thought it was a little genius doctor, but I didn’t expect that this ability to kill people was much more skillful than the ability to save people. It would be no exaggeration to say that I was born specifically for killing.

"Forgive me, Mr. Qin. I have only this skill. I can't help you!"

After solving two problems in a row, Xue Yu's face was no longer happy, because there was nothing he could do about the third problem!

When eight thousand soldiers went on an expedition, military supplies were not a small amount, at least tens of thousands of stones of grain, tens of thousands of taels of silver, and various other materials.

In a short period of time, even if Xue Yu is extremely wise, he can't do it.

Without enough food, the soldiers are hungry, so how can they fight to fight the enemy bravely?

Without enough money, you cannot buy a large amount of medicinal materials and make weapons. The previous two problems are not really solved!

"I am not only skilled in medical skills, but also superior in strategy. I have solved two problems in the army in succession. I am already very grateful!

I can assert that if my friend joins the army, he will definitely have a bright future in the future, and it will be no problem to become a third- and fourth-rank official!"

Of course, Qin Liangyu knew that if he had no money and food, he could not fundamentally solve the problem.

However, she was overjoyed to get the prescription and weapon graphics. These things may be able to save the lives of thousands or tens of thousands of soldiers on the battlefield, and even reverse the situation in Liaodong!

Qin Liangyu admired Xue Yu's talents very much, so he made a hint in his words, inviting Xue Yu to join the army, hoping to cultivate himself as his right-hand man and protect the descendants of the Ma family in the future!

"Haha, thank you for your appreciation by Shin-Ship, but I was studying hard for the sages and wanted to pass the imperial examinations and entered the officialdom. I did not have the heart to hold my strength and hold my own sharpness, so I did not dare to obey my orders!"

It was a good way to join Qin Liangyu's command and make achievements on the battlefield, but Xue Yu thought a little, was still very tactful and firmly refused.

Of course, it is an excuse to enter the officialdom. Xue Yu never had the intention to be a civil servant because the future is a chaotic world!

In troubled times, it is a world where military generals can make achievements and achieve success, so being a soldier is the king!

Is the real reason for rejection? Xue Yu doesn’t want to surrender!

Xue Yu thought that if he joined this army, he would definitely be highly valued by Qin Liangyu, and he would be promoted step by step with his contribution. In 10 or 20 years, he could become an official position such as a general and a deputy general.

After that, there is no room for improvement!

Because this army is a soldier formed by the Qin and Ma families, only the direct descendants of the Qin and Ma families can command this army!

No matter how powerful an outsider like Xue Yu is, no matter how great his contributions are, he can only act as a military advisor or deputy general, and be a wedding dress for others, and will never be the commander of this army!

A man, a real man, would rather be a chicken head than a phoenix tail!

Xue Yu is humble on the surface, but is actually quite arrogant at heart. He will never surrender to others. If you want to be, you will be the boss!

When I was a wanderer, I was the boss!

No matter what I do in the future, I will still be the boss!

As for the army, after reaching the northwest, I will form a Xue family army with strong combat power, strict discipline, and obedience to my orders.

"Since that's the case, I wish my friend a title as soon as possible!"

"Thank you, Mr. Qin!"

Xue Yu was unwilling to join the army, and Qin Liangyu couldn't force it. Congratulations were a matter of exposing the matter, but she vaguely felt that the reason for Xue Yu's rejection was not that simple!

"Xue Xiaoyou is extremely wise and doesn't know what opinions do you have about the battle situation in Liaodong? I hope you can give me some advice!"

"Okay, I'll talk about the situation in Liaodong again. Please give me a sword!"

If you invent a few weapons, at most you are the talent of craftsmen. You can guide the country and forcefully wield the world. That is the talent of the commander!
