The sudden change in the weather is not humanly controllable, at least not now.
The sudden arrival of the army disrupted the rhythm of the Han army and the Sassanid army, and because of this heavy rain, the Sassanid side did not know that the Han army had moved.
The fight between the scouts was extremely fierce, and in bad weather, there were Sassanid scouts who wanted to brave the rain to go back, and the speed would definitely be more than three or four times slower than usual.
In this era, no one would be willing to rush in the rain, and the army would not march in the rain except for the urgent needs of 100,000.
The rain showed no sign of abating from the moment it began to fall, and the sky was constantly thundering with lightning, and occasionally when lightning fell, a lone tree was struck, and in an instant a strong light flashed, and then thick smoke rose up, and the wood became charred and burned.
The thunderstorms on the plateau are really very dangerous, the height of the clouds themselves is about 200 meters or even lower than the ground, and the clouds that rub against each other have lightning, and when they split downward, they will hit something higher, and if there is a metal attraction, it will inevitably be split again and again.
Li Jun received a report that 16 people had been struck by lightning, 14 of them were engineers who were setting up camp, and the remaining two were soldiers who had nothing to do and raised their spears.
This is not the first time Li Jun has encountered such a thing, when they are fighting in the grassland, if there is a thunderstorm, there will always be an accident of people being struck by lightning, the higher the altitude, the more dangerous the people under the thunderstorm, the correct way is to find a cave to hide, or no one can guarantee where it is absolutely safe.
"When is this rain going to fall" Li Junshen frowned: "Don't be the next ten days, half a month or more" The Han army is an outsider, not so familiar with the local climate, there are some locals who have asked for surrender, but because they are not their own people, the information is not 100% credible.
Li Jun also understands that even if what the locals say is true, those locals are just because they have lived here for a long time and use their past experience to make judgments.
"Luckily, it's on high ground."
Gai Nie said happily: "Otherwise, with such a heavy rain, there will be flooding soon." ” For them, if there is any benefit to this rain, the only advantage is that they don't have to worry about the water source being difficult to replenish.
Water sources in this area are not easy to find, and there is no water that can provide tens of thousands of people to splurge on them.
The nearest river to the camp was ten miles away, and even if it was only that distance, it would not seem easy to replenish the water every time.
Naturally, there is water in the army, which is basically some water source packed in strict wooden barrels, but the barrels cannot be loaded with water for too long, otherwise the water will soon change its taste.
If conditions permit, no one will quote the water source that has changed its taste, and only if it is absolutely necessary, will not care.
The rain was very heavy for the first three days, and it gradually became lighter on the fourth day, and the scouts braved the rain to reconnoiter the surrounding area, reporting that some low-lying places had become ponds, and the river ten miles away had risen to the point where the water level had flooded the perimeter, making the river, which was only about ten meters wide, nearly thirty meters wide.
By the seventh day, the sky was no longer cloudy, but the clouds had not all dispersed, but the sun was finally visible.
"Seventy miles to our west, there was a Persian army of about 60,000 men."
The news that Gai Nie said was just sent back: "I don't rule out that there will be more later, it's just" The scouts were delayed for so long, entirely because of the weather, and then there were heavy rains for many days, not only did the land become soft and muddy, but the appearance of some places also changed completely, such as streams in places where there were no streams, and in some places it simply became lakes with large areas but shallow water levels.
The change of terrain makes the people who originally figured out the route have to re-explore again, and the intelligence spy will naturally be less efficient, mainly because the time for detection to be sent back is extended.
This situation was not only for the Han army, but also for the Sassanid army on the other side.
"It's not time to march right now."
Gai Nie smiled and made a big circle in front of the sand table: "The land is soft and muddy, and it affects not only our army. ” After the rain, the ground will definitely change, just one or two people walking is naturally not a big problem, as a large number of troops, as a large number of people, a road will be repeatedly trampled on, the road will become muddy is an inevitable thing.
As an army with a large number of wagons, once the roads become muddy, the chance of the wheels getting caught becomes infinite, and if you really want to force the march, you can walk five or six miles a day.
Due to a series of weather influences, it was actually more favorable for the Han Empire's Western Expeditionary Corps.
The Western Expeditionary Corps originally did not plan to start a big battle with Sassanid at this time, and while resting, they were also waiting for the follow-up troops, and the other was that the partial division led by Dou'a needed time to completely solve the Western Gaoche.
The Sassanids, who were unable to fight, were the hosts and the side that was about to be invaded, and they absolutely did not want to see the Han army coming from afar enough time to recuperate, adapt to the local climate and find more information, and then win allies nearby.
The most important thing for the Sassanians to do now was, of course, to organize their men to build a defensive line, and at the same time to interfere with the Han army, which was not firmly established.
Under this premise, if Habibullah hadn't thought that the forces at hand were seriously insufficient, he would have wanted to take the initiative a long time ago.
The Yulin Army, who were ordered to fight but were trapped in place, were depressed and disappointed when they were suddenly trapped.
"Long history."
Li Jun asked: "If the cavalry attacks, can it?"
Of course, Gagnie didn't want to stay where he was, waiting for the moisture on the ground to dissipate on its own, but he said, "It's useless to have less of it. ” Li Jun's idea was to dispatch at least 3,000 cavalry, and then let them divide them into a brigade of 1,000 people and march apart.
"Five thousand."
Li Jun looked at Gai Nie and asked, "How?"
Gai Nie thought about it for a while, and thought that five thousand was indeed a very appropriate number, and it could pose a big enough threat to the enemy army without having to carry exaggerated quantities of supplies.
"I'll lead the team myself."
Li Jun is actually just trying to get Gai Nie's opinion, and Gai Nie will take action if he disagrees, it's just the number of troops dispatched.
He saluted to Gai Nie: "The headquarters, I will entrust it to the long history" A series of military orders were issued, a large number of light cavalry were assembled, and when they learned that they were going to go on the battle, everyone looked relieved.
They originally set out on the expedition with great momentum, but they were forced to stop in place after marching for more than 30 miles, and it can be said that they were defeated halfway.
After hiding in the tent for so many days, they were actually already stuffy, and when they heard that they were ordered to go on the expedition, they didn't have the excitement when they left the main camp, and some just felt that they didn't have to be stuffy in the tent all the time.
Soldiers need to organize their equipment and some tools that may be used, and horses need to be fed fodder and carry out the necessary suit checks.
From Li Jun's order to the preparation of five thousand knights half an hour later, the speed was actually quite fast.
Four thousand light cavalry and one thousand cavalry archers are the strength of Li Jun's order, they are standard one man and three horses, in addition to the main and auxiliary war horses, they are a pack horse carrying supplies.

The troops were divided into three groups, with 1,000 knights on the left and right flanks, and 3,000 knights and more than 500 auxiliaries in the middle army.
When they came out of the camp, the horses' hooves were trampled constantly, and by the time four or five hundred rode over, the earth on the ground had been trampled into mud.
The particularly rammed walkways of the barracks are all like this, and you can imagine what the camp should look like.
Li Jun ordered: "Line up in a vertical line and push forward horizontally" The soldiers shouted: "For the country's wings, like the prosperity of the forest" There are only two armies in the Han Empire that have their own special battle numbers, the Yulin Army is the sentence "For the country's wings, such as the prosperity of the forest", and the other Tiger Ben Army is "out of the car Peng Peng, the flag is fierce".
If these two armies were on the same battlefield and were ordered to attack together, they would shout in unison, "The Son of Heaven has ordered me to fight in all directions", which is a unique benefit and a kind of pride for them with a special name.
A knight with a war horse under his crotch, plus a secondary horse and a pack horse, occupies a space of about two meters.
Each knight is more than three meters apart from each other, and even if there are five hundred knights in each vertical line, the total length of the formation is more than two thousand five hundred meters.
Some of the soldiers who were not counted were enviously watching the robes arranging the formation, and with their vision, the many soldiers lined up from left to right to the end of the sky.
The troops began to move at the sound of a strong trumpet, and the land was trampled by the hooves of the horses, and each of them stepped down and moved forward, and the ground could always sink into a hoof pit of about ten centimeters.
Anyone who understands cavalry actually understands that once the ground is soft, don't drive the horse to move with all its might, otherwise the chance of the horse losing its front hooves is infinite.
If it weren't for that rain, or if the conditions on the ground permitted, seventy miles would have been only about two hours for a cavalry capable of marching at a normal pace.
But now, Li Jun calculated the speed, and seventy miles would have to walk for a day and night As the lieutenant general of the Yulin Army, Li Jun was anxious to fight, and Habibulla on the other side was even more anxious than Li Jun.
Habibullah didn't even think about the impact of the terrain, and when the rain stopped, he immediately ordered the uprooting of most of the camp, leaving only a few sick soldiers to be housed.
A sudden rain added nearly 4,000 sick people to the Sassanid side, and more than 100 people died in a high fever.
On the side of the Han army, although they set up camp early and urgently made ginger soup, there were still more than 300 people who suffered from the cold.
What is better than the Persians is that they have handled it properly and have mature Chinese medicine methods, and no one has died of wind and cold for the time being.
Before the fighting, Habibullah had 5,000 men on hand, and 1,000 fewer were left in the camp to be cared for.
When the Sassanid army was opened, the marching speed of the infantry was not fast, but it became slower due to the influence of the terrain, and it was too much to walk five or six miles a day.
Two troops marching at turtle speed, they discovered each other's presence two days later.
Li Jun naturally could not have marched day and night, but walked for a day plus seven hours, and lost more than 40 people due to various accidents along the way, but the loss of horses reached 537.
In terms of scouts, it was the Yulin Army that first discovered the Sassanid army.
On the Sassanid side, Habibullah learned of the existence of the Feathered Forest Army about four hours late.
They will meet so quickly, thanks to the two days of bright sun, although the sun does not dry the ground thickly, at least it will not become muddy when stepping on it.
Waiting for Habibullah to get the news that there was a Han army ahead, a dark shadow appeared on the horizon in less than an hour.
"Stop" Habibullah was actually startled when he saw that the black shadow on the horizon was so long, and confirmed to the scout: "How many Han troops are there?"
The scout was not so sure and said: "Look at the length, it should be twenty or thirty thousand" In fact, he didn't dare to get too close to the Han army, even if it was far away, a team of thirteen people got rid of the pursuit of the Han army scouts, and only four people were left in the camp.
This group of Yulin troops is elongated in the marching formation, and the thickness cannot be seen under the line of sight at the same height, and then the dust and smoke trampled under one person and three horses will be thicker.
When Habibullah heard that there were twenty or thirty thousand, his face stiffened, and then he shouted: "Organize a blocking formation" This Sassanid army, they lost 5,000 combat strength because of a rain, and there were no 2,000 or 3,000 people on the march, not all of them died, but they suddenly fell ill and couldn't stand it or disappeared, and they lost about 8,000 combat strength before they opened with the Han army.
However, as a Persian, Habibullah has long been accustomed to losing some combat power before the start of the fight, and this situation of the Persians is really old history, and there is really nothing to make a fuss about.
The Persians had a history of sending 300,000 troops, and they had not yet started a war with the enemy, waiting for the commander to have a few soldiers, and were horrified to find that there were less than 200,000 left.
The Sassanid infantry were ordered to get busy nervously, and they had some horses with them, but they had lost most of them on the march, and they were hurrying to bring up the rest of the horses.
The soldiers with long weapons stood shoulder to shoulder under the shouts and whips of the officers, and then released the long weapons in their hands diagonally.
Li Jun had already seen the Sassanid army on the opposite side, and because of the telescope, he could see it very clearly.
"About 50,000" Li Jun looked down at the ground, especially observing the place where the horse's hooves had trampled behind him, and shouted to the herald next to him: "Order the left and right flanks to charge" The art of war in Zhuxia is cloudy, and the brave wins when they meet on a narrow road.
It was not an accident that they encountered the enemy now, and the battlefield was not a narrow road, but Li Jun found that the other party was a little confused:
