When the Perak army entered Hengyuan Village, the soldiers of the new annexed army in the village had already fled, and the forage was burned to the ground, but fortunately, the distance between the grain and the baggage dumping place was far away, and it was not affected by the fire. This time, in order to attack Wanjiazhai, the Mongolian army prepared a month's logistical baggage. Now most of these materials have been taken over by the Thunderbolt army, except for the burned forage, which not only includes weapons such as swords, spears, bows and shields, siege equipment, but also daily necessities such as sackcloth, straw sandals, cooking utensils, and more than 100 wheelbarrows for transportation. This wheelbarrow is called "chicken car" in Shu, and it is said to be the prototype of the "wooden ox flowing horse" invented by Zhuge Liang, the prime minister of Shu during the Three Kingdoms. Of course, the most important thing in the seizures was grain and silver money, and it was roughly estimated that there were 100,000 catties of grain, about 3,000 taels of silver, and a large amount of iron money.

Although it was late when he entered the village, in order to prevent the Mongols from counterattacking, Cao Ergou still ordered the spoils to be carried to the mountains overnight. He estimated that the Mongolian army of 100 people would definitely not give up after escaping, and would definitely return with men and horses. The ruined Hengyuan village of this city is not even complete now, and it is not a place that can be defended for a long time. Cao Ergou believed that in the case of a small number of people, the Thunderbolt army would definitely cause heavy casualties to the Mongolian army, but he would also suffer great losses. For the Thunderbolts, who are still very weak, they really can't take that risk. As long as the Thunderbolt army retreated to the mountains and defended the danger, the Mongol iron cavalry, which had lost its mobility, was helpless in the face of strong defensive fortresses and sharp firearms, and could not take advantage of half of the advantage.

After the 3rd, 4th, 5th, and 6th companies of more than 400 people were busy all night, most of the loot was transported to the mountain road before dawn for temporary storage, and only silver coins and other valuables arrived at Wanjiabao. Although the Perak soldiers drank pine needle water every day, there was no night blindness, and there were a large number of torches to illuminate, but it was too dangerous to transport grain and other bulk materials when the road was narrow in the dark, so soon after entering the mountainous area, Cao Ergou ordered the personnel to rest in place, and the materials were temporarily piled up on the mountain road and transported to Wanjiabao after dawn. In order to prevent a sneak attack, he asked the three companies with the strongest combat effectiveness to set up a tight defensive formation in the mountain pass.

The silver that arrived at Wanjiabao overnight really surprised Ouyang Xuan. It is not surprising that a large number of weapons and food were seized in Hengyuan Village, after all, this is a logistics base for the new annex army to attack the mountains, but what is the use of carrying silver taels that have nothing to do with the march to fight? Could it be that the new annex army wants to use these heavy silver taels to smash the Thunderbolt army? Just when Ouyang Xuan was puzzled, Yu Zhu, who was standing on the side, said the reason. When Cao Ergou led people to pursue the Mongol army and attack Hengyuan Village, Yu Zhu brought two companies of the garrison battalion to assist in guarding Wanjiabao according to Ouyang Xuan's order.

"Brother Xuan, this money is not useless, but it is very useful, if it didn't have these silver money, these traitors would have run out long ago." The Thunderbolts despised the new annexes who had surrendered to the Mongols, calling them traitors. Seeing that Ouyang Xuan was still puzzled, Yu Zhu explained the reason in detail. Since ancient times, the combat effectiveness of the armed forces has had a great relationship with the military system. The reason why the Sui and Tang dynasties were strong was because of the implementation of the government soldier system, the government allocated tax-free land to the government soldiers, the government soldiers cultivated and trained in their spare time, and in wartime, they brought their own swords, armor, weapons, horses, and grain to go to war. However, since the Tang Dynasty, land annexation has been serious, and the Juntian system has been destroyed, and the government military system can no longer be maintained. Therefore, from the period of the Five Dynasties and Ten Kingdoms, the conscription system was popular. However, everyone knows that the combat effectiveness of the army engaged in the conscription system is not good, and there are two solutions given by the two Song Dynasty. One is to hope that a brave man will be born under a heavy reward - an ordinary soldier in the forbidden army of the two Song Dynasty can earn an annual salary of 100 yuan (not considering the situation of being deducted by the commander), which is equivalent to 75,000 yuan according to the price of grain, which is simply an unprecedented high salary. The high salary of raising the army directly led to the military expenditure of the two Song Dynasty Dynasty accounting for more than 70 percent of the fiscal revenue, and it became the most unsolvable of the "three redundancy" problems. However, due to the corruption of the government and the abolition of military discipline, the phenomenon of eating empty quotas and drinking the blood of soldiers in the Song army reached the level of madness. Even the most elite Song army border army, the actual number of troops can only reach seventy percent of the establishment, and the actual number of most Song troops has three achievements. In areas where there has been no war for a long time and is not very important, the soldiers who can breathe can account for one or two percent of the number on the roster, and the generals who lead the troops can be regarded as conscientious. And the troops that only exist in the military registers of the Privy Council and do not even find a ghost shadow in the local area are not without .......

Compared with the shortage of soldiers due to empty salaries, why the Song army fought was a more fatal question. At the time of the Jingkang Change, the general of the Western Army led the army to aid Taiyuan, but was surrounded by the Jin general Wanyan Zonghan (i.e., Sticky Han). Although the situation was critical, the Song army was not without the strength to fight, so the battle situation was very anxious. But suddenly, the Song army collapsed inexplicably. Why? Because of the urgency of the military situation, the money was not enough when the army was dispatched...... According to the unspoken rules of the time, no matter what the soldiers of the Song army did, they had to get "piecework wages" - they had to pay for pulling out the camp, they had to pay for marching to a certain mile, they had to pay for engaging with the enemy, there was a price for winning and losing, and even how much money should be paid for each round of crossbow arrows fired was clearly marked. At that time, the Song army was surrounded, and they all relied on firing the divine arm bow to block the Jin army's offensive, but when they shot and shot, they shot the waist bag of the seed master. As a result, the soldiers who had not been able to get the predetermined reward for a long time were too lazy to work for others, and simply dispersed in a hurry, and had to die miserably among the teachers who became the commander of the light pole.

These new annexed troops who had not long surrendered to the Mongols, except for Xiong Ben's subordinates, were just bandits dressed as officers and soldiers, whether it was Dayi County or Qingcheng County, they still inherited the old customs of the Song army, and also brought a large amount of silver with the army. Of course, it is impossible to make these soldiers who lick the blood on the knife edge desperately by handing out some money. Indulging in the looting of people and property after winning is the main means of motivating these outlaws.

Yu Zhu's words made Ouyang Xuan thoughtful, on the one hand, he was lamenting that the official army of the Southern Song Dynasty was really hopeless, and on the other hand, he also thought of the military system of the Thunderbolt Army. The current government discrimination and persecution and the looting and massacre of the Mongols have united the Perak Army due to the pressure of survival, but when the existential crisis is solved, how to ensure the combat effectiveness of the Perak Army? It seems that in addition to strengthening ideological and political education so that every soldier can understand why he is fighting, it is also necessary to establish a complete and motivating military system.
