In the era of cold weapons, swords, swords, halberds, these, supplemented by bows and crossbows, etc., mainly relied on the city for defense, and mainly relied on charging for offense.

But in fact, most wars are still the last word, who has more people wins, who has better weapons who wins, only when these factors are similar, it is the turn of other factors, after all, the cluster effect is obvious, there are several times more people, but the increase in combat effectiveness is definitely more than several times, you can win 10,000 more than 20,000 with less, but it is almost impossible to defeat 100,000 people.

But in this case, it will be very troublesome for Duan Ye, it is obvious that he only has one county in Dunhuang now, and with the manpower and material resources of one county in Dunhuang, it is a very difficult thing to seize Liangzhou, even if he takes Liangzhou, he wants to seize the world with the territory of just one state, under normal circumstances, it is almost impossible to do.

In fact, throughout the ages, if you want to dominate the world, in addition to having opportunities and a certain social background, you need enough talents and a strong army, in fact, geographical factors are also very important, not all places can be used as a base area, the danger of mountains and rivers, the solidity of rivers, and the strength of passes are all very important.

Although the old saying has long been said: "Danger can be feared, but not feared!" "What determines everything, in the final analysis, is still the people's hearts and minds, or whether they stand on the tide of history, but history is zigzag and spirals forward, and there will always be many accidental moments, such as a horseshoe may cause a horse's horse to stumble, and a horse's stumbling hooves are likely to throw off the knight on the horse and cause death, if it is a coincidence, the knight is likely to be a king, and the death of the king is very likely to cause the rise and fall of a country.

But from the beginning, in fact, everything is still the same horseshoe, but the horsehoe is not done, it is not necessarily a conspiracy, let alone any historical inevitability, but it is likely that the blacksmith is in a bad mood for a while.

From Duan Ye's point of view, choosing Liangzhou is actually no choice, if he is willing, he is actually more willing to choose other places, such as Jiangnan, for example, Hebei, many places are okay, but when he appeared, he was in Liangzhou, and everything was almost necessary.

In fact, very early on, those shrewd strategists in this mysterious country have long discovered that if the competition for the world is compared to playing Go, then the situation of the mountains and rivers of the whole country is tantamount to a chessboard like Go, and as we all know, when playing Go, the beginning is very important, and the truth of the golden horn and silver edge grass belly is also applicable in the competition for the world.

Then just like Luozi, on this non-standard Go board, Guanzhong, Hebei, Southeast and Sichuan are its four corners, Shanxi, Shandong, Hubei and Hanzhong are its four sides, and the Central Plains is its central hinterland.

Although the world is so big, the proportion of the area occupied by these places is not large, but the decisive role in the wars of the past dynasties is mainly the above nine regions, and the subordinates are generally under these places, and the princes who want to achieve their careers basically start from here, not elsewhere.

The reason why these places can play a decisive role is that practice and history have repeatedly proved that the importance of these places is almost certainly related to the unification and division of the world, to the rise and fall of one dynasty and one generation, or to the survival or death of the Central Plains regime in the war between the Central Plains regime and the nomadic peoples outside the Central Plains.

As the old saying goes, "the capital of mountains and rivers" is only in those places where there are both mountains and dangers that can be relied on, and there are rivers and waterways that can circulate are easy to form strategic places, and the reason is also very simple, there are mountains and rivers, which can block the enemy's attack, can be encircled into a hinterland suitable for development, and are easy to defend and difficult to attack, and are most suitable for being the national capital.

Of course, for the rulers, the strategic significance of mountains and rivers is the same, and the significance of mountains is to block, and the most important thing is that there are channels to pass; The significance of the river lies in its circulation, and it is important to have a stronghold to hold it.

If there are dangers in mountainous areas, it is easy to establish a base area in a chaotic situation, form a local order, and accumulate strength; There are rivers and waterways can circulate, it is convenient to send power to the outside, easy to expand outward, and it is also convenient to intervene in the overall situation, most of the above nine strategic places have these conditions, further, just like playing Go, the normal opening order, often also occupy the corner first, and then occupy the side, and finally compete for the middle of the belly, if most of the princes can successfully seize the world, looking back, it is generally from Guanzhong, Hebei, Jiangnan, and starting from Sichuan, but can only be divided by one side, it is difficult to compete for the world, the only hope, Gongsun Shu, who has a time and a person, is because of the defects of his own personality, which leads to missing opportunities and losing opportunities.

Of course, the person Duan Ye admired the most when he was a teenager was called Wu Qingyuan, he played Go, that is, he started directly from Tianyuan, and he could win many battles, so, in the final analysis, it still depends on who will play this chess, and in fact, there are really people in history who can start from Henan and seize the world, but there are not many such examples, because the difficulty is too great.

It's just that for Duan Ye, his location is very embarrassing, Liangzhou, where he is located, has a lot of mountains and mountains, but there are almost no big rivers, but there are many deserts, not to mention anything else, just from the perspective of feng shui, it is very unlucky.

In addition, although Liangzhou is very rich in this era, it is not the place that the princes of the Central Plains focus on, and it does not belong to the several important places mentioned above.

So Duan Ye actually knows very well that even if he relies on all kinds of luck to capture Liangzhou, it is impossible to go to the next level, and the best result can only be to learn from Dou Rong and sell himself and the soldiers and civilians of Liangzhou at a good price, but Duan Ye has spent so much effort to come from that distant era, but he doesn't want such a result.

If you want to be, you must be the biggest official, if you want to do it, you will do the biggest thing, Duan Ye not only wants Liangzhou, but also the world.

And to fight the world, the most important thing is the army, Duan Ye has already started his huge plan, he has the confidence and certainty to build his army into the most powerful army in the world within three years.

Now the key is how he builds the army and how he gets three years.
