"Hehe~"

Zhang Han chuckled lightly and moved a chess piece on the map. Knowing that the overall situation had been decided, Zhang Han breathed a long sigh of relief and relaxed.

Spring is the season of revival of all things, the grass is slightly green, the trees are sprouting, the ice in the pond has long been dissolved, the breeze brings the smell of earth, and the early spring sun shines on the body warmly, which makes people feel comfortable.

The manservant's affairs were busy from autumn to spring, and he had a rough appearance, and Zhang Han was caught by Cen Hui to play chess as soon as he had some time. However, this is also good, since the new birth, there is not much leisure time to enjoy, and Zhang Han feels precious. Sitting under the tree by the pond and enjoying the sunshine, Zhang Hanqi is very casual.

However, Zhang Han, who does what he wants, rarely has the upper hand today.

Cen Hui lowered his head and studied for a long time, but he had to admit that he was powerless to return to the sky, and he lost this game of chess. If you lose, you lose, but the problem is that you lost too badly, and you were killed and wiped out. Seeing Zhang Han's smiling appearance, Cen Han snorted, very dissatisfied - he was too disrespectful of his teacher.

"Han'er, being a teacher is a criticism of your usual command style.

In the beginning, you kept your Chinese defense watertight, and as a result, you were defeated; Later, it was a little better. You gradually have a big picture and know that you have to think about it comprehensively, which is very gratifying for you.

However, you still continued your previous command style, but you only expanded the scope of the defense, and you fought a war of attrition in eight out of ten battles......"

Zhang Han is cautious by nature and likes to plan later. He uses soldiers solidly and steadily, and likes to use regular soldiers, but he is not as exaggerated as Cen Hui said. He likes to defend first and then wait for an opportunity to attack, and he has clever strategies, but he rarely relies on strange soldiers.

In other words, he made a surprise attack to contain it, and it is good if he succeeds, but it will not affect the overall situation if he fails. On the other hand, in order to achieve this goal, the odd soldier will be subject to various restrictions, and even if it succeeds, it is generally not enough to determine the victory or defeat.

Zhang Han is good at training and defending. Generally speaking, Zhang Han has a broad vision, but he is still a little immature, his personality is a little too cautious, his planning ability is medium, the winner wins, the loser loses, and that's it. Cen Hui fought against him, and nine times out of ten, he would be able to take advantage, but if he killed a thousand enemies and lost eight hundred, his own losses would not be small, and he was somewhat depressed.

"Consumption is good consumption, it is difficult to take advantage, but it is not much to lose. But how did your fighting style change today?

……”

Today, Zhang Han's ease, playing chess as he likes, and repeatedly making surprise moves, it was mainly strange soldiers, which made Cen Hui very uncomfortable for a while, and then he defeated Cen Hui.

"Ahem, being a teacher doesn't mean that it's not good if your style changes. But ......"

Zhang Han smiled and listened to Cen Hui's complaints. Cen Hui is a good teacher, he is knowledgeable, rigorous, and has a deep study of scriptures, history, law and military affairs, but sometimes he is a little wordy, Zhang Han has long been used to it.

Wargame was proposed by Zhang Han when learning temple arithmetic, and Cen Hui perfected it.

The original meaning of the temple calculation is that in ancient times, a certain ceremony was held in the ancestral temple to discuss and decide on the battle strategy, and it can also refer to the pre-war decision-making, or the battle strategy. The ancients often discussed the designated battle strategy in the temple before going to war.

Sun Tzu divided the temple into five aspects (five things: Tao, heaven, earth, general, and law) and seven situations (seven calculations: "Who is the Lord?"). Who will be capable? Who has heaven and earth? What is the law? Which of the soldiers is stronger? Soldiers' training? What is the reward and punishment? ”）。

This kind of analysis was very advanced at the time, and it was sufficient when doing strategic analysis. However, this is only a very rough analysis, and it depends entirely on the character of the analytical talent. If the analyst is smart, objective, and has sufficient intelligence, the analysis is accurate. Otherwise, it's hard to say.

Moreover, there is no clear criterion for it, and it is difficult to judge accurately. For example, the right time and place. The location can be judged, and there will be no mistakes basically, and there will be a lot of accidents in the sky. In addition, the most important "Tao", that is, the people's heart, it is estimated that no ruler will admit that he is "Taoless".

Therefore, the temple is easier said than done. When Zhang Hanxue was dizzy, he couldn't help but think of the war game. Wargames quantify everything, and relatively speaking, there is a lot less error.

Zhang Han doesn't know much about wargames, but he still knows maps, dice, chess pieces, and other big things.

"The positive six sides, with a total of six sides, represent the six directions in battle: front, back, left front, left rear, right front, right rear. It can basically represent various situations during the war.

……

The use of dice is because in combat, there are many accidental situations, for example, in an attack, an infantry attack, the attack power can determine the range, but in specific operations, the effect of the attack may be the lower limit of this range, or the upper limit. How do you know for sure?

I can't say for sure. At this point, it's determined with dice.

And the weather. In combat, the weather has a great influence, and what kind of weather a combat unit encounters can sometimes determine the outcome of a battle.

However, what kind of weather it encountered is also unknown, and it is also impossible to determine.

At this time, it can also be determined with dice.

And the unexpected ......"

Zhang Han shook his head when he said proudly.

"Stop, wait a minute," the attack is okay, use dice to determine the weather, Cen Hui has an opinion, "How can the weather be determined with dice?" ”

Zhang Hanzheng said that he was happy, but he really didn't think about how to be sure, he thought for a while before he spoke.

"Well, the weather, it's easy to do. Let's say the battle takes place in the fall, and the location is Bian County.

The weather in spring, summer, autumn and winter in Bian County is roughly clear to us.

Autumn rains a lot, with occasional torrential rains, generally speaking, seven out of twelve days are still sunny, three days are light to moderate rain, and the remaining two days are heavy rain. Every four heavy rains, there will be a torrential rain.

In this way, we can compile a table with a total of 48 items, numbered 1~48. Of these, 28 were filled in sunny days – which can also be subdivided, 12 were filled in with light to moderate rain, 7 were filled in with heavy rain, and 1 was filled in with heavy rain.

Next, you can take an eight-sided dice and a six-sided die, and calculate the value [Note 1] according to a fixed formula, and check the number, where the weather is the weather encountered on the day. ”

Cen Hui nodded thoughtfully, in this way, all kinds of situations encountered can be determined in this way.

"The same is true for emergencies.

Here's an example. If the troops are on the march, there will be occasional losses. However, there will be no big losses, and it is not an emergency. However, when the troops were hit by heavy rains for several days in a row, the possibility of an emergency was greatly increased. This is possible, you can also make a table and use the dice to determine it.

If you are in a mountainous area, you may experience flash floods, sparse trees, and mudslides. If you are on the riverside, you will encounter a flood; There are no such things on the plains, but wetlands can become swamps.

Etcetera.

……”

Zhang Han's words were like opening a window in Cen Hui's heart and seeing a novel world. According to Zhang Han, a war can happen on paper, which is really "on paper". Cen felt a wave of vertigo, and he instinctively sensed the significance of this—if he could get the job done, there was no doubt that he would go down in history and be on a par with the sages.

So, Cen Hui put aside all affairs, spent two months concentrating, and initially established a set of rules. Subsequently, Zhang Han and Cen Hui began to "talk on paper". As the number of games increases, some inconsistencies are discovered and then modified.

By the end of the fourth year of Jianning, the rules of wargame had formed a manuscript of more than 200,000 words and 57 volumes. Wargames are also officially divided into two types: the first is the kind that the two of them are playing, and the actions of each other are clear at a glance, and two people can; The second is more practical and practical, but requires at least three people (with an additional referee) to proceed. If the number of people continues to increase, it is completely possible to simulate a battle realistically. However, it requires a large number of personnel and often requires a long time to prepare. Zhang Han and Cen Hui are the most common ones, or the simple version.

After packing up the chess pieces, Zhang Han was ready to play another game with Cen Hui, but Cen Hui was not in much of the mood to play chess. He came to Zhang Han today, not just to play chess.

[Note 1]: Let the value of the eight-sided dice be A, and the value of the six-sided dice be B, and the fixed formula is (A-1)*6+B.

[Be kind, read a book and smash the ticket]
