Chang'an is not far from Songzhou, didn't you see that the Tibetan envoys arrived in Chang'an so quickly?

But this is not far and it is only a relative distance, in fact, in ancient times, there was nothing not far, and going out for dozens of miles was a long way.

Don't look at the arrival of the Tibetan envoy so quickly, but he only had a few retinues, and he rode horses, and it took more than ten days to get from Songzhou to Chang'an.

But in fact, there are more than 1,000 miles away from Chang'an to Songzhou, and ordinary infantry is an elite soldier who travels thirty or forty miles a day, and an elite soldier who travels fifty or sixty miles a day is the elite soldier, and this trip is at least twenty days up.

Don't feel slow, and don't take the later generations to walk more than 100 miles a day, it's not a concept at all, what is the road of the later generations, what is the road of the ancients, what kind of shoes are the shoes worn by the later generations, and what are the shoes worn in the ancient times.

Of course, don't compare ourselves with our revolutionary ancestors, it was a force that fought the world by willpower, and there is no comparison.

And even if you can walk more than 100 miles a day without anything, the next day will definitely not be as much as the first day, and it is almost predictable that the distance you can walk every day is shrinking.

Because people are not machines, I can't simply calculate that I can walk 120 miles a day at most, and 1,200 miles in 10 days.

Speaking back to ancient times, in fact, there is no big road or small road, leaving the city for dozens of miles, all the roads are basically not wide, and there are not a few people walking side by side, and the team of 10,000 people can drag five or six miles or even longer. These are talking about the road conditions, and the equipment they have to carry, like the government soldiers are all self-prepared weapons, food, equipment is almost more than a dozen catties, and the better ones have dozens of catties, anyway, it doesn't wait, it is hell to carry so many things to go fast.

And the most elite twelve guards are all uniformly rationed by the imperial court, and they don't need to carry their own food, but the infantry is at least twenty or thirty pounds of weapons and leather armor, and the cavalry will be heavier.

If it is like Niu Jinda, Wu Yuanqing and the elite of the 10,000 vanguard they bring, then they will carry more weight.

Not to mention the iron-making and steel-making methods provided by Wu Yuanqing, as well as the discovery of several large coal, that is, coal deposits in Hedong Road and Guanzhong, Datang's steel production has been increasing day by day in recent years.

The lives of ordinary people and the country's infrastructure are not involved for the time being, but the equipment of the entire army of Datang has been updated and upgraded.

Like the Xuanjia Army, the most powerful unit under the command of Emperor Li Shimin, that guy has thousands of people, but he has repeatedly performed miraculous feats, Li Shimin once used 1,000 Xuanjia elite soldiers to break Wang Shichong and beheaded more than 6,000 people. Pen @ fun @ pavilion wWw. ｂｉｑUｇE。 infoIn the battle of Tiger Prison Pass, which decided the ownership of the world, Dou Jiande led more than 100,000 elite main forces to support Wang Shichong, and Li Shimin only used 3500 Xuanjia elite soldiers to reinforce Tiger Prison Pass, and as a result, Dou Jiande broke more than 100,000 people, and Dou Jiande only led hundreds of horsemen to escape.

"Zizhi Tongjian" records the Xuanjia Army: "The Qin King Shimin selected more than 1,000 elite horsemen, all dressed in Xuanjia, divided into left and right teams, so that Qin Shubao, Cheng Zhijie, Wei Chi Jingde, and Zhai Changsun were divided into generals. In every battle, the people of the world were taken as the vanguard by the Xuanjia Shuai, taking the opportunity to attack, and everything was destroyed, and the enemy was afraid of it. Xingtai servants shot Qu Tutong, and Dou Liang of the Emperor praised the generals according to the camp tun, and suddenly met Wang Shichong, and the battle was unfavorable. Qin King Shimin Shuai Xuanjia rescued him, Shichong was defeated, and his cavalry general Ge Yanzhang was captured, and more than 6,000 people were captured, and Shichong escaped. ”

Although this text is very short, the combat effectiveness and role of the Xuanjia Army can be seen.

But the size of such a powerful Xuanjia army has always been around a few thousand, and most of the time it is only three thousand people.

It's not that Li Shimin doesn't want to have more troops like this under his command, but because he is limited by the lack of steel production, he can't arm more Xuanjia troops.

But with Wu Yuanqing's contribution to the steelmaking method, such a restriction no longer exists. Datang has enough steel production to redress the army.

Not to mention the expansion of the Xuanjia Army, it has also been replaced with the best armor weapons, and the horizontal knives used are all of the 100-steel level.

The equipment of the twelve guards and horses guarding Chang'an is inferior to that of the Xuanjia army, but the weight of the infantry is also about forty catties, and the cavalry is higher, which can reach seventy catties, because the armor of the cavalry is Mingguang armor made of stainless steel.

That is, the 10,000 horses and horses of the vanguard are all selected cavalry in the twelve guards, not mixed cavalry, otherwise it will take a month to go from Chang'an to Songzhou, but even after the cavalry load increases, the marching speed is slower than before the change of clothes, and it is almost twenty days to run down for more than a thousand miles.

When it was still thirty miles away from Songzhou, Niu Jinda asked the army to stop to rest and bury the pot to make rice.

"General, there are still thirty miles to Songzhou, why do you stop here." Niu Jinda's lieutenant asked a little puzzled. But his eyes kept looking in the direction of Songzhou, and it was full of longing for the city and the beds in the city.

Looking at the longing in the red and swollen eyes of this lieutenant, Wu Yuanqing couldn't help laughing.

"Why are the overseers laughing, do you know that my plan is not true?" After glaring at the lieutenant general, Niu Jinda turned his head to look at Wu Yuanqing and asked.

"Hey, I said Lao Niu, we also partnered a few years ago, is it necessary for you to always supervise the army and supervise the army for a short time?" Wu Yuanqing didn't answer the question, but instead took care of the question of the title.

Hearing Wu Yuanqing call him Lao Niu, Niu Jinda pursed his mouth, and felt that he had a toothache and said again.

Speaking of which, he is similar to Wu Yuanqing in terms of official position and title, Wu Yuanqing was still his boss when he led troops to Lingnan before, it stands to reason that there is no problem with the friendship of the same generation, and his age is not that he is much older than Wu Yuanqing, and he must be a generation higher.

But he and Cheng Biting Jin, Qin Qiong and these people are brothers in life and death, and they are commensurate with each other, while Wu Yuanqing Guan Cheng Biting Jin, Qin Qiong and others are all called uncles.

If he and Wu Yuanqing had a relationship with each other, wouldn't he be a generation lower than Cheng Biting Jin, Qin Qiong, and others, Niu Jinda, who was a generation shorter, was unwilling.

But Wu Yuanqing didn't know if he didn't think about it so much or if it was on purpose, he opened his mouth and closed his mouth to call Niu Jinda Lao Niu, and asked Niu Jinda not to be polite, just call him by his name.

Niu Jinda didn't want to say anything more to Wu Yuanqing about the issue of titles, so he brought the topic back to the previous question and asked, "Aren't the prison guards curious why I am here to let everyone rest?"

Cut, it's boring, Wu Yuanqing muttered a sentence Seeing Niu Jinda looked at himself fixedly and asked for an answer, so did the deputy general, so he had to explain casually: "Isn't this a very simple thing, I came all the way, and I saw that I was only a stone's throw away, but I didn't stop and didn't go in. Either you don't want to rescue Songzhou, or you don't want the Tibetans to find out about our arrival. So obviously, the second one must be the reason why you stopped, and as for why you don't want the Tibetans to find out that we are coming, I think it's also obvious, because you want to catch the Tibetans off guard, and you want to attack them at night."
