The Song army swaggered and sent sword and shield men, and then under the escort of the cavalry, they went all the way north along the battlefield, and hacked to death all the wounded soldiers who fell to the ground along the way, and the cavalry of Daxingfu hesitated a few times, and did not have the courage to attack and turned around and retreated into the city.

The corpses of 30,000 people and horses were scattered in an open field two miles long, and the autumn wind blew with a strong bloody breath, and the flesh that had lost its vitality gradually became cold and stiff, fixing the last picture of life in this autumn windy day.

And just an hour ago, they had dreamed of winning a permanent piece of land from Kublai Khan, where their people would thrive in the daily hunger and cold.

The guards sent by Kublai Khan were carefully recorded not far away, and recorded all the details of what happened on the battlefield today, and all the tactical cooperation of the Song army that they observed.

Zhehu looked very carefully in the city, until after the Song army had cleaned up the battlefield and gathered the few available supplies, someone pushed a cart and pulled firewood, dragged the corpses into a pile with a large hook, and stacked them together with the firewood.

The burning of corpses on the battlefield is Zhao Tianyou's strong request, no matter what the victory or defeat of the enemy or the enemy, as long as the conditions are met, the corpses will be burned immediately, and it is not allowed to delay for a day. Some people privately said that Zhao Tianyou had a benevolent heart and was unwilling to abandon the corpses of the soldiers in the wilderness, even if they were all local soldiers, they would be cremated, but Zhao Tianyou never explained the real reason for this matter.

There is a little respect for the lives that have been lost, and the reason why he really emphasizes the need to dispose of corpses in a timely manner is for the physical and mental health of his own soldiers. Not to mention people's superstitious sayings, there is some evil corpse poison in the corpse, large-scale corpse decay will affect the air clean, pollute the water source and cause plague, the most important of which is the breeding and infection of bacteria.

In the absence of the invention of anti-inflammatory drugs to equip the army, the infection caused by drinking water and food is too serious, once the source of the disease is generated, because the means of isolation and treatment cannot keep up, there are often precedents of thousands of people falling ill at the same time overnight, so Zhao Tianyou attaches great importance to the cleaning of corpses on the battlefield.

The sun gradually turned to the west and set, and a fire ignited on the bloodstained earth, and dozens of piles of burning corpses burst into the sky, and the slanting sun hanging in the west seemed a little dim. The two warring sides tacitly understood that there was no next move, and they were both watching the burning fires from afar, of course, the thoughts in their hearts were different, some were excited, some were sad, and some were worried about their fate tomorrow, whether they would also become corpses burning into ashes in the fire.

Kublai Khan and his subordinates deliberated in the main hall overnight, and analyzed all the methods used by the Song army today to find ways to deal with it, but it was difficult to have a better way to confront the Song army.

The Yuan Dynasty's workshops for producing gunpowder and casting cannons never stopped, and they also sought to hire many Han craftsmen, but there was no breakthrough. The performance of gunpowder always stays in the initial stage, and it will be used to make a firecracker, but it cannot reach the power of application on the battlefield, and the casting of cannons is even more problematic, and it is impossible to get something that can be compared with the cannon of the Song army.

The gap between this is not something that can be figured out by the head, the technology of coke melting iron and steelmaking is not a secret, when the average blacksmith builds a hundred steel-making weapons, it has been widely used, but in the deeper technology, the Yuan Dynasty did not master it at all.

However, there is a detail of the Song army's troops, which has been repeatedly discussed by them, that is, how much influence the rain and snow have on the Song army's artillery firing, and whether it can reach the point where the cannon cannot be fired. Because in the analysis of several battles to the end, it is still artillery that plays a decisive role, if the weather affects and reduces the power of the Song army's artillery, then the cavalry of the Yuan army can easily defeat the Song army.

For this reason, Kublai Khan ordered Guo Shoujing to preside over the experiment, although it could not be made into practical gunpowder, but the general characteristics are similar, that is, in the barrel of the cannon, there is dew condensed at low temperature every day, and the barrel must be heated and damp with charcoal fire every day.

After Guo Shoujing's experiment, there were results, rain and low-temperature fog and other reasons, will affect the performance of gunpowder, too much water in the barrel will also affect the launch, resulting in a squib or explosion. However, Guo Shoujing also knew that the Song army had taken corresponding precautions against these natural conditions such as weather or rain and snow, and the Yuan army could not overestimate the impact of the weather on the Song army's combat capability, otherwise it would suffer a big loss.

But he didn't tell Kublai Khan directly, what Kublai Khan needed was a hope to defeat the Song army, even if it was a small chance, even if it was to pay more price, he would gamble. Besides, the severed heads outside Bazhou City, Guo Shoujing still knows it vividly, don't say something wrong at an inappropriate time, this is a skill to protect your life.

However, God quickly gave Kublai Khan a chance, and that evening it was so foggy that he could barely see his fingers, and his clothes would be wet with a thick fog when he stood in the field for a while. The morning fog is sunny and the evening fog is cloudy, the evening fog is not collected, and the drizzle is drenched, not only will it not be sunny tomorrow, but there is a ninety percent chance of light rain.

The cavalry of the 200,000 Yuan Army began to prepare for war in the middle of the night, assembled from three military camps near the capital of Yuan, and slowly walked towards the direction of Daxingfu in the night.

Kublai Khan wanted to personally go into battle to supervise the battle, but Guo Shoujing insisted on stopping several ministers, and did not agree to Kublai Khan on the front line no matter what, showing all kinds of concern and protection intentions, and Kublai Khan's heart was warmly moved.

Zhehu now rests and sleeps in a fixed place, for fear that the shells of the Song army will kill him at night, and often hides in the cellar where the people in the city store grain, and today he received an order from Yuan Dadu to make him excited.

The effect of rain and dampness on gunpowder is obvious, if it can be connected to the rain for a few days, without the order of Yuan Dadu, he himself dares to lead the army out of the city to kill the enemy, today's weather is really an excellent opportunity to defeat the Song army.

Zhehu jumped out of the cellar and gave orders to his subordinates in a loud voice.

"Order the whole army to assemble at the north city gate at midnight and prepare to go out of the city to kill the enemy!"

The Daxing Mansion immediately took action, and the Yuan army, which had been depressed, finally waited for the opportunity to send troops, and rumors that the fog and rain would cause the Song army's cannons to fail had begun to circulate privately among the soldiers.

Ten steps away from the fog, you can't see people's faces clearly, just like when Li Heng took advantage of the fog to attack Guangzhou, you don't need to guess Zhao Tianyou knows that in such weather, if Kublai Khan didn't come to gamble, he really wouldn't be worthy of being his opponent.
