Xiao Hui is an excellent commander, after the victory in this battle, he felt a burst of hidden worry, what is it, he didn't expect it, but when the smoke was filled, the black smoke filled the entire desert, he also changed color, he finally thought of a possibility, but this is too poisonous.

Xiao Hui doesn't know, why did the other party dare to do this, isn't this a salary draw from the bottom of the kettle?

This is the territory of Western Xia, is it possible, this territory, Western Xia wants to give up.

In fact, Yuan Hao did this, but also blood in his heart, this is the only way to connect Western Xia and Liao, even if it is a desert, it is relatively barren, and the caravans that pass through here every year do not know how many.

When the oasis is destroyed by the wall, it will take a long time to recover, and in the future, not only will the cost of passing it rise a lot, but even some of the environment will deteriorate to the point where it is impassable.

This is a very terrible thing, for Yuan Hao, the loss of a long stream of water may last for more than a hundred years.

Yuan Hao had no choice, Western Xia itself was too weak, he couldn't compare with Liao Song, he could only retreat, let go of this desert, take another road, bypass, it was acceptable, but it was the cost of time and money.

What he saw was not the same as the real thing, but he had to be vigilant, so he took the risk of sending a large number of scouts.

Soon, the scouts sent by Xiao Hui searched the oases for 200 miles around and found that most of the oases had been destroyed.

One, two, three, from the initial disbelief, to the final numbness, especially after investigating everything, it was found that not only all the grasslands were burned, but even the water sources were polluted.

If he could, Yuan Hao would poison the water source, but there was not so much poison, he chose a black oil that came out of the ground and polluted these water sources.

Layers of black oil completely pollute the water, so dirty, even if someone dies of thirst, they will not drink it.

If Zhao Xin is here, he will definitely recognize what these black oils are, this is natural oil.

Oil, itself is a mineral, there is no invention of the problem, internal combustion engine and a variety of chemical energy machines, has become one of the symbols of modern civilization, airplanes, ships, automobiles, sea, land and air these three, which one can be separated from oil, it can be said unceremoniously, oil has become the blood of modern industry, any fluctuation of it, will make the industry have a huge shock.

Xiao Hui is not Zhao Xin, I don't know what this oil is, but the samples that the probes got back were given to the horses to drink, but the horses didn't drink at all, and they were forcibly poured down, and the next day, all of them died, and there was no one left.

Oil is a nightmare for living beings, and it is fatal to drink it directly.

In this case, Xiao Hui still doesn't know that this water can't be drunk at all, it is poison, thinking of at least 50 oases explored by Tanma, all of them are like this, Xiao Hui's face changed directly.

The most unlikely, the worst case, just like this, is still the most extreme state, all the trees are burned, even if they are left, it is not enough to support the consumption of the army.

The consumption of tens of thousands of troops is an astronomical amount, even if it is Xiao Hui's 9,000 cavalry, it can produce huge consumption.

still carried a lot of supplies, but he had to lay a good foundation for the follow-up 50,000, as well as the Liao Xingzong who drove the expedition, 100,000 people, 200,000 horses, and a lot of logistics forces, all of which together would be an astronomical amount.

Xiao Hui is a person who knows the soldiers, he deeply knows the importance of logistics, the 60,000 people he carries, and he also carries the most supplies, and even slows down the route of the march because of this, if it is not for the logistics supply belt is too much, how can he only bring 9000 cavalry out, it is because it is too slow, he was reprimanded by Liao Xingzong.

Even Xiao Hui, the privy envoy of the Northern Court, was reprimanded like this, because he walked too slowly, others would not be able to, Yelu Chongyuan took the initiative to retreat 300 miles after losing 4,000 horses, although he did not achieve the strategic goal, it was also regarded as a retraction into the territory of Liao, and there was no need to worry about the problem of supplies, the follow-up Liao Xingzong, with 20,000 Tielin troops and a large number of elite horses, what should they do.

Xiao Hui knew that they didn't even bring enough basic supplies, at most they only carried a few days' rations.

The Liao State still attacked with the original idea, they did not take into account the problem of logistics, and the idea of fighting was to eat the enemy, but Yuan Hao was desperate to clear the wilderness on his own land, and even when the losses were not hesitated, everything became meaningless.

A small amount of grain and grass, the combat effectiveness of the Liao State can not be brought into play, the Liao State is mainly cavalry, among the 100,000 troops, there are less than 40,000 foot soldiers, the rest are cavalry, the pastures owned by the Liao State are also very terrible, it is difficult to find a horse in the Northern Song Dynasty, but in the Liao State, the horse is a very common thing.

Therefore, the number of 100,000 military horses is very high, the Tielin Army, an average of one person and three horses, ordinary cavalry is also one person and two horses, 60,000 cavalry, with an average of 150,000 war horses, and 50,000 logistics horses, these horses, if they are taken to the Northern Song Dynasty, each of them can be used as good horses, and even the existence of horses.

100,000 people, the daily food and drink is an astronomical number, plus 200,000 horses, this is not a common grassland in Liao, this is a desert of more than 500 miles, what if there is no supply.

Any living organism needs to eat, and the creatures that don't need to eat are only a very small number of them, and they are not conventional eating methods, whether it is a human or a horse, they have to eat, and even the things that horses need to eat are much higher than humans.

The shadow shrouded in Xiao Hui's heart, the initial victory, even the capture and defeat of twenty or thirty thousand people, such a hearty victory, did not make Xiao Hui happy, he had to find a solution to this problem.

He is a pioneer and opened the way for Liao Xingzong, if it ends like this, he himself will not be able to forgive himself.

Xiao Hui ordered Jin Sucheng and the cities under the command of Beiyuan to work hard to prepare supplies, even if there was no food, at least, they had to concentrate a little grain and grass.

Liao does not produce grain, but there are a lot of pastures, spend a little effort, get hay, may affect the herdsmen's wintering, but it is not impossible to step up the time and continue to collect, the most important thing is that this battle is not allowed to fail.

In history, Xiao Hui also did this, and the consequence of this was that he saved more than half of the horses and all the soldiers, and his combat effectiveness weakened a lot, but 100,000 people were still complete, which was already the limit of what Xiao Hui could do.

But this effort made the Liao State fall into passivity, and the Liao army, which had lost most of its combat effectiveness, was obviously weak to the disadvantage in the battle with the Western Xia, coupled with Yuan Hao's strategy and kamikaze.

Under the favorable time and place, it was attacked by more than twice the power of Western Xia, and in the end, in this battle, the Liao State was defeated, and even Liao Xingzong was almost captured.

What Xiao Hui can do, this is already the limit, if there is no Zhou Wenxiu, everything will still develop in that direction, but now there is more Zhou Wenxiu.

It's not that a young general like Zhou Wenxiu is more powerful than a battlefield general like Xiao Hui, that's impossible, just by experience, Xiao Hui will completely blow up Zhou Wenxiu.

But behind Zhou Wenxiu, there is the entire Northern Song Dynasty as the backing, and after this plan is determined, all aspects of this plan are taken into account, and in the end, a complete plan is formed.

One person counts the short, and everyone counts the long, in order to calculate Yuan Hao's possible response plan, as well as a solution, the Privy Council of the Northern Song Dynasty has gone through countless deductions.

The literary world of the Northern Song Dynasty was at its peak, and it had developed to a considerable height in terms of military skills and strategies, not to mention, the collective study of the Privy Council, and even the characteristics of Yuan Hao, as well as the usual practices, were taken into account.

If Yuan Hao can really clean up all the walls and fields, the Northern Song Dynasty has no other way than to fight hard and reserve a large number of materials, this is no chance at all.

In the huge desert, how many oases are there, there are really a lot, the meager manpower of Western Xia, it is impossible to destroy all the oases, they just need to find out, the least damage, in fact, the desert is so huge, there are many oases, not every one of them is mastered by Western Xia, and not every one of them is destroyed.

According to the characteristics, Yuan Hao's ideas, coupled with the manpower of Western Xia, basically determined a most likely method of implementation, Yuan Hao, as a matter of destroying the way that the Liao State came over, and the most important ones can be, among them, there is at least a range of 150 miles, there is no oasis, even if the road is changed, it will not solve the problem.

If the Liao State has no preparations, 100,000 people, in the desert, the terrible natural environment, under the premise of sufficient conditions, even 100,000 people will not be able to resist the power of nature.

That was an extreme situation, and even considering the help of the right time and place, it was impossible for the Liao army to starve to death, and the reason was that it was immediately.

The horse is a huge weight, the average adult military horse, almost more than a thousand catties, once it is impossible to do anything, lack of drinking water and food, kill the horse for water, cut the horse to eat meat, these can solve the imminent dietary problem, but the future will be more difficult.

This is probably also the fundamental reason why Liao Xingzong disagreed, he didn't realize at all that killing horses would have to bear the premise of weakened combat effectiveness, once the combat effectiveness of the Liao army was weakened and the morale was unstable, under the attack of the Western Xia army, would they still be spared?
