The advent of light machine guns, coupled with 50 to 60 mm grenadiers or mortars, developed the infantry squad tactics with light machine guns as the core, and then could extend the infantry tactics of Germany in World War II and the three-three system tactics of the Volunteer Army.

Of course, it's too early to talk about infantry squad tactics, and before the light machine gun is not equipped to the squad, it is better to honestly play machine gun defensive warfare. As for the attack, it can only rely on a wide range of roundabouts, anyway, don't expect to break through the enemy's defense line head-on.

After another military meeting based on the Russo-Japanese War, Zhao Dongyun, who was going back to the study, saw Li Wan in front.

When Li Wan saw Zhao Dongyun, a smile immediately appeared on her face: "I've seen Lord Zhao!" ”

Zhao Dongyun nodded and smiled: "Miss Li came back from Tianjin?" ”

Li Wan also smiled: "I just came back today, I bought some books when I was in Tianjin, and you said that you bought a few of them, so I bought them and sent them to you!" ”

"Oh!" Zhao Dongyun didn't ask for any books, but said as he continued to walk forward: "That's thank you, you still remember!" ”

Li Wan kept up with Zhao Dongyun's pace in small steps, walking side by side with Zhao Dongyun, her height was slightly shorter than Zhao Dongyun, her red lips only reached Zhao Dongyun's shoulders, one was wearing a plain white pleated skirt with pink edges, and the other was wearing a brown and yellow officer's regular uniform.

The two walked slowly, followed by Li San and Li Wan's maidservant girl are already very knowledgeable and backward several figures, although Zhao Dongyun and Li Wan have always been friends, but Li Wan has nothing to do to come to Zhao Dongyun, and Zhao Dongyun has always been kind and kind, sometimes the two will stay in Zhao Dongyun's study for a long time, if there is no personal relationship here, it is not believed that Li San is killed.

So at this time, Li San consciously didn't act as a light bulb, he and Li Wan's maid followed far behind, and said to Li Wan's maid while thinking nonsense: "Xiaohe, when did you say that your young lady fell in love with my family?" ”

The little girl named Xiaohe rolled her long eyelashes: "What are you talking nonsense, when did my young lady like Lord Zhao!" ”

Li San disagreed: "Isn't this obvious!" ”

Xiaohe wanted to defend something, but she opened her mouth but didn't say anything, this little girl was too young to tell a lie, and with her little head, she already knew that her young lady liked that Lord Zhao, so she didn't defend it anymore and just snorted coldly!

The south courtyard of the Li family is not small, this place was originally a part of the Li manor, and when it was built, it was not used as the main residential courtyard, but as a partial courtyard, so there are not many buildings in the courtyard, on the contrary, there are more garden landscapes, and it can be regarded as a place for the daily play of the Li manor in the past.

Since it was sent out by the Li family and his son to serve as Zhao Dongyun's headquarters residence last year, although some forbidden posts have been added to the periphery, the internal changes are not large, that is, a large number of headquarters office personnel have been stationed in the front yard hall, and the place where Zhao Dongyun lives has still maintained its original appearance.

There are many evergreen flowers and trees behind this south courtyard, and during the rockery and flowing water, the people walking in it do not feel too much of the bleak autumn now.

"I don't know German writing either, but I heard from the owner of the bookstore that it's all about military affairs, so I bought it first regardless of whether it was right or not." Li Wan said softly.

Zhao Dongyun said: "Thank you Miss Li, I haven't had a new book here for more than a month!" ”

In order to give himself a more intuitive understanding of the contemporary era, Zhao Dongyun is very interested in some contemporary military, political, and economic-related books, especially military books, and has been collecting various books through various channels in the past few years, such as diplomats and students who have been sent to Germany to buy artillery and machine guns by Beiyang, and Zhao Dongyun will ask them to buy books from Germany and France and bring them back to China when he has the opportunity.

Then, Zhao Dongyun actually didn't say that he was going to study the theoretical content of these Western books, he generally read it with an attitude of understanding and borrowing, and finally used it to improve some of his military theories.

Li Wan is also a person who likes to read, although she reads some literary works, but when she goes to the bookstore to see other military, political, and economic books, she will also help Zhao Dongyun buy them.

"Thank you, I'm just dropping by!" Li Wan pulled the ends of her hair on her forehead with her left hand as she spoke, and then continued: "Anyway, I'm going to see my aunt's, and I also want to buy books myself!" ”

In a small place in Jinzhou, it is estimated that there are some Four Books and Five Classics, but it is difficult to find books in foreign languages, and you have to go to Shanghai or Tianjin, where there are more foreigners or simply say that there are more concessions to find them.

"It's said that the courtesies are often exchanged, since you brought me a book, I'm afraid there is nothing good to give back to you, some time ago, I had someone make some freshly squeezed juice, and it's good to add a few pieces of summer ice, let you taste it!" Zhao Dongyun said casually, this juice is not a novelty, but ordinary people don't think of getting it.

Although Zhao Dongyun does not reject some of the living habits of this era on weekdays, he has the soul of the 21st century, although a few years have passed, it is still difficult for him to adapt to the contemporary lifestyle, not to mention anything else, just the fact that there is no electric light at night and can only use kerosene lamps and candles makes him deeply disgusted.

Therefore, intentionally or unintentionally, he will try to copy some of the living habits of later generations, so he never lives in those antique courtyards, even the furniture used in life is more rejecting the traditional style, but chooses Western-style furniture and small western-style buildings that are closer to the modern style.

If you want him to live in a traditional courtyard, go out and sit in a sedan chair, wear a horse coat and keep long braids, shake a folding fan and go to the green building to sing about the country's broken mountains and rivers, etc., that is something that he can't do if he is killed.

This juice is just one of them, in the summer, get a freshly squeezed juice and add a few ice cubes taken out of the cave, it is very cool and quench your thirst, a few days ago I remembered it and ordered my subordinates to prepare some.

After a short time, the two sat down in a gazebo, and the topic of their mouths had already shifted from books and juice to Zhao Dongyun's career in Germany in the past few years.

"Germany is so far away, and you're alone, won't you be unaccustomed to it?" When Li Wan said, "At that time, I am afraid that you had just turned twenty years old!" ”

Zhao Dongyun said: "At that time, although there were not many students in my country in Germany, there were also a few students from the Tongwen Museum, Cheng Huangyun and Yongku, and they could occasionally meet each other, but most of the time they were still alone in Berlin, but it was good to be alone, so that they could calm down and learn something, otherwise they would not learn anything if they were wasted in two or three years." ”

When Zhao Dongyun stayed in Germany, there was no trend of studying in Germany in China, and in the years before Gengzi, there were only Zhao Dongyun and a few sporadic scholars studying abroad in the Tongwen Museum, and there were many after Xin Chou, but Zhao Dongyun had already returned to China at that time. Therefore, his study in Germany back then is different from those international students who are studying in Japan and Germany now, and now these international students are more or less taken care of by classmates due to their large number, but Zhao Dongyun will be a real loner, not to mention that there are classmates in the Berlin Military Academy, and there are not even a few Chinese students in the whole of Germany.

Although it was not the first time Li Wan had heard Zhao Dongyun say this, there was a hint of yearning in her eyes: "I also want to study abroad, but my family won't let me!" ”

Li Wan doesn't want to go to Berlin, she wants to go to Paris!

Paris in this era is much more famous than London and Berlin, and it is the world's fashion, literature and even financial center, and young people from countless countries want to study and play in Paris.

Zhao Dongyun also knew that Li Wan said that she wanted to study abroad was just an excuse, and it was almost the same to go to play! Although Li Wan has a much broader vision than ordinary contemporary women, she has only read a few more foreign books, compared with other contemporary women from big families, the gap is probably that Li Wan reads romance novels in foreign languages, and other boudoir women read traditional romance novels such as The Legend of the West Chamber, which is not much different in essence.

So studying and increasing her life experience are not what she wants, she just yearns for the romantic Paris depicted in many books.

In this era, it is not so easy to study abroad, not to mention those who are one out of ten thousand, in addition to having a foundation of modern knowledge, they also have to require their families to have rich financial support, and if they go to Germany, Britain and other western countries to study, the minimum standard is three or four hundred pounds, which is still the minimum standard of living for students, and it is guaranteed that you will not starve to death after paying the tuition. And those who are accustomed to being young masters and young ladies in their families go out to study at their own expense, and a thousand pounds a year is not enough to spend.

Studying abroad is usually three to four thousand pounds, which is two to three thousand pounds old, which is converted into 20,000 to 30,000 taels of silver.

These tens of thousands of silver are naturally nothing to a wealthy family, but it is almost unbearable for an ordinary businessman and landlord family.

Even if it is a local tyrant family like the Li family, let him supply his descendants to study at his own expense, it is estimated that he will grit his teeth and take out these tens of thousands of taels of silver, but a woman like Li Wan who is destined to marry is not to expect the Li family to come up with tens of thousands of taels of silver for her to study abroad.

At the end of the Qing Dynasty, students from Britain, the United States, France, Germany and other countries were either official students who had high hopes, or they were self-financed students with a lot of money, so if you saw any self-funded students studying abroad in the late Qing Dynasty and the Republic of China who were still shouting that they were proletarian revolutionaries after returning to China, you can spit on his face, and your rich second generation is called a Mao proletariat!

Zhao Dongyun is also understandable about Li Wan's thoughts, if he wants to go out for a walk more, see more people, and listen to more things, it is better than staying in the boudoir every day to mourn the flowers and grass.

So casually said, "You should go, whether it's Paris or London, it's very different from ours!" ”

"Really?" Li Wan seemed to be already imagining something different.
