It was a very troublesome thing for a large army to go on a campaign, at least in ancient times, with the mobilization of grain and grass, the conscription of farmers, and the mobilization of government soldiers, etc.

It's just that these are the affairs of those ministers in the court, for Lu Hanyang, this kind of thing is very simple, you don't need to bring anything, just summon the red-crowned crane, and then sit on its back, fly to the north for an hour, and then just enjoy the mountains and rivers.

That's right, it's that simple, he doesn't have to worry about eating, drinking, or even walking. Flying for an hour is enough to cover the distance of a day's march of a large army. There is even an excess part, which can be regarded as a free gift.

After this red-crowned crane was caught by Lu Hanyang, a spirit initiation rune improved its sanity, and it also strengthened its muscles and bones, and now its flying speed is full of thirty percent.

Don't look at it much, but it used to be able to fly 150 miles in an hour, but now it can fly 200 miles. The march of a large army for a hundred miles a day is already very fast, and even the cavalry will not exceed three hundred miles a day.

However, when marching on the land, restricted by the geographical environment, it is impossible to run a straight-line distance of 300 miles in a day, and it needs to be roundabout and tactful, and the straight-line distance is much worse.

Therefore, it is enough for Lu Hanyang to travel for one hour every day, mainly not to be too far away from the army, after all, the marching route is not familiar. Otherwise, he would have been able to fly to the steppe in one day.

It is not a problem for the red-crowned crane to fly for ten hours a day, that is, two thousand miles, and the distance from Chang'an to Jiuyuan is only six or seven hundred kilometers in a straight line.

Of course, this is walking in a straight line, and it is still difficult for Lu Hanyang to distinguish the direction in the air. Because the geographical environment of this era is too different from that of a thousand years later, just like the last time I returned to Chang'an from the Indochina Peninsula, I ended up running a big circle in Tibet.

Anyway, Lu Hanyang was very leisurely along the way, the marching speed of the army was very slow, and it took a long time to get from Chang'an to the grassland, and it was basically a month after arriving at the place.

So Lu Hanyang walked all the way upstream, rushing for an hour every day, and the rest was to see how the people's lives were on the way.

Although he said that he was leisurely, he was not happy, just because the life of ordinary people in this era was too difficult. All the way north, not many people in the area passed through were able to have a full meal at this time.

Why? Because now is the time of green and yellow, the previous year's grain has been eaten, and this year's grain has not yet reached the harvest time, so it is basically digging wild vegetables and eating bran buns.

This made Lu Hanyang feel that Li Er's current approach was a little eager, and he originally thought that the imperial court had really eased up, but in fact, the people of the Tang Dynasty had not really been fed and clothed, so he wanted to go north to regain the lost land and coerce the grassland.

"It seems that my appearance has put pressure on this heavenly khan! Otherwise, I wouldn't have been in such a hurry to conquer the Quartet. Lu Hanyang thought to himself.

That's right, his appearance did make Li Er feel that his power was oppressed, but there was no way to alleviate it, because Lu Hanyang was too strong, so Li Er couldn't see any possibility of victory.

So Li Er wants to vent, what should I do? It is to distribute the divine power of this immortal to these surrounding foreign races. That's right, it is to let those aliens know that there is such an immortal behind Datang, and then Li Er uses them to calm the grievances in his heart.

This is the method that Li Er came up with, and it is also the reason why he invited Lu Hanyang to participate in the military operation of entering the Tang Dynasty. Let the aliens see that there are such immortals in Datang, and they dare not resist the rule of Datang at all.

In this way, Li Er's heart will be much more balanced, and when he can't resist, he will oppress those who are even lower than him. It's like in the modern world, when the president criticizes the manager, and the manager goes to the director for trouble.

Now Lu Hanyang is the domineering president of this Datang Times Group, although he doesn't care about things, but he treats me, the most powerful power (force), everyone dare not disobey.

And Li Er is the CEO of this Times Group, he does everything, but the most powerful power has nothing to do with him. So he needs more people to be bullied by this domineering president, and he is the one with the biggest head.

These surrounding alien states are the heads of the subsidiaries or departments below, and the CEO was beaten by the president, so none of you small leaders can escape the punishment of the CEO. That's it, vent your frustration on the people below. This is a very common way to reduce stress.

But now is the time for the group to recruit people, and the CEO pulls the president over to the town, so that all those who are unwilling will be suppressed, so that they willingly accept the president's rule.

In other words, Lu Hanyang was actually pulled by Li Er as a nuclear weapon this time, deterring the three tribes of the grassland so that they did not dare to make a big killing weapon.

"What do the people need? I need food, I need food, but now I don't have any of these, and the army is transporting millions of stone of rice, but this is military food, and it can't be given to these people! Lu Hanyang felt that he should do something.

The reason why a state is a state, not a family or a family, is because it is a country made up of countless families. A country without these millions of people would not be a country at all.

The people are the foundation of a country, no matter when it is, no matter what system. It doesn't matter if it's feudalism, capitalism, or even socialism.

Because although the people are weak and can be bullied, they are not as high as those scholars, nor are they as good as the nobles who have the merit of being a dragon. However, they are the most fundamental layer of the entire Tang Empire, and only when they grow food can they feed countless nobles.

Only when they manufacture all kinds of commodities can these families enjoy life, without the people, the entire Tang Empire is a castle in the air.

At this time, at the turn of the spring and summer of the second year of Zhenguan, when the people were living in hardship, the ruling class of the Tang Dynasty was preparing to use troops abroad. Countless people and government soldiers were dispatched, so that the foundation of the entire Tang Empire was shaken.

Originally, there was no such a big military operation this year, Li Er ate the Weishui Alliance the year before last, and wanted to be ashamed, but he couldn't do it because of the emptiness of the treasury, so he could only recuperate.

And now the Weishui Alliance has been burned by Lu Hanyang, and Datang has won. also allowed Li Er to keep his treasury, so that the entire Tang Dynasty had a little savings, and the taxes from all over the country were also handed over to the treasury in the first year of Zhenguan last year.

Therefore, Li Er had the capital to fight back against the grassland, plus the rice planted in Lingnan for one season, and more rice planted in the areas of Zhenla and Linyi, so that the grain and grass had no worries, so that there was this time of the northern expedition to the Turks.
