"I have a way", Ouyang Xuan walked up to Li Shuang, took out the climbing rope in his backpack and said.

"Hurry up, tie the trees on both sides of the river with ropes, and grab the ropes to cross over", Li Shuang ordered loudly.

The people hurried across the river. At this time, Li Shuang led ten soldiers to defend in the direction of the cavalry, 5 people half-squatted in front to support the wooden shield, and 5 people set up spears diagonally behind to block the official road. The Mongols came quickly, and when Ouyang Xuan grabbed the rope and crossed with everyone to the opposite bank, the neighing of horses was faintly heard in the distance. At this time, the officers and troops who were lining up for defense had not yet crossed the river, and the rest of the soldiers except Li Shuang were all afraid, and the team began to stir.

Li Shuang shouted loudly and ordered the remaining soldiers to cross the river one by one, while going to untie the ropes on the trees. The soldiers who had crossed the river were lined up with wooden shields, behind the shields were soldiers with bows, and soldiers with spears stood far beyond the range of their bows and arrows. Ouyang Xuan took a closer look at this team of 50 people, the main weapons were wooden shields and spears more than three meters long, less than half of the personnel had long knives, and there were only more than ten bows. At this moment, Yu Zhu was leading the archers to draw the strings, facing the other side of the river.

When Li Shuang jumped into the water with the rope, the sound of horses' hooves was already ringing rapidly behind him, and a sharp sound sounded in the air. The arrows were shot one after another, and the horses were blessed at high speed, with great strength, and the wooden shields of the officers and soldiers on the other side of the river rattled, and the arrows were submerged in the wooden shields, and the arrow feathers were still trembling. Yu Zhu led the archers to counterattack as well, but they were quickly suppressed by the fierce rain of arrows, and could only occasionally fire cold shots from the gaps in the wooden shields. At this time, including Li Shuang and two soldiers, they were still swimming along the rope in the river. Among the three men in the river, the first soldier had just climbed the embankment when he was shot in the back by a Mongolian ranger who was still a hundred meters away, and then rolled into the river.

Seeing this, Yu Zhu hurriedly led the archers to stand behind the wooden shield and risk shooting at the Mongol rangers, which made the Mongol rangers slightly frustrated, and they dismounted to find a place to hide. The soldiers hiding behind the shield pulled the rope together and pulled Li Shuang up to the river bank with all their strength. Li Shuang hid behind the shield array with a roll, Rao was so that he still had a feather arrow diagonally inserted in his back, fortunately protected by leather armor, the skin and flesh were extremely shallow and did not hurt the muscles and bones, but an archer standing next to Yu Zhu was not so lucky, he was hit by an arrow in his forehead, and he swallowed his breath immediately with a muffled snort. Seeing this, Yu Zhu sighed, this archer was his deputy, that is, the support of his own team, and a good brother who had followed him for many years.

Everyone slowly retreated under the cover of the shield array. At this time, the soldier who had been washed away was already in the gentle place of the water a hundred meters downstream, standing in the thigh-deep mud, and slowly moved towards the shore.

After retreating beyond the range of bows and arrows, the soldiers turned around and galloped one after another without waiting for Li Shuang's order, and at this time, the Mongolian rangers were blocked by the river and restrained their horses in front of the broken bridge. Ouyang Xuan hurriedly looked back during his run and found that the Mongolian cavalry was no more than 10 people, and there were no less than 20 horses. Seeing the Song soldiers go away, a moment later the Mongol rangers also turned their horses and headed towards the upper reaches of the river.

When Ouyang Xuan and the others ran to Yongkang County out of breath, it was already twilight, and the gate of Yongkang County was closed at this moment. Just as Yu Zhu and Li Shuang went to call for the door loudly, there was a rapid sound of horses' hooves in the distance, which made everyone who was about to take a breath anxious, and also made the faces of the city head soldiers change greatly, and they refused to open the city gate. Li Shuang held up the document under the city, and tried his best to declare to the city gate guards that he had come to Yongkang County on the order of the Chongqing Mansion Pan Commander, and also shouted the name of Xie Jinyong, the commander of Yongkang County, and the rest of the people also begged for help, but the Yongcheng guards were still unmoved and refused to open the city gate. In the midst of the noise, several soldiers surrounded an officer and walked up to the city, and it was Cao Zhengyong, the lieutenant of Yongkang County. According to the official system of the Southern Song Dynasty, the inspector and the county lieutenant were both officials in charge of public security, but the inspector was responsible for rural affairs, and the county lieutenant was responsible for public security in the city. Li Shuang and Cao Zhengyong originally knew each other, and at this moment, Li Shuang was like a drowning man meeting a life-saving straw, and shouted loudly: "Lord Cao, the Tartar soldiers are chasing very quickly, open the door quickly", "I am waiting to come on the order of Lord Pan, open the door quickly." Cao Zhengyong first looked at the official road in the distance, and then looked around the anxious people in the city, twisted the beard under his chin, and said unhurriedly: "Lord Li, according to the military system of the Great Song Dynasty, you can't open the city gate under the circumstances, please take care of yourself", after saying that, he arched his hand towards Li Shuang, and then walked down the city tower in the midst of the pleading and angry scolding of the soldiers outside the city. To say that the reason used by Cao Zheng is also in line with the official regulations of the Southern Song Dynasty, that is, under the situation of unknown enemy situation, the city gate cannot be opened rashly. It's just that now although the sky is dark, and there are cavalry attacking, Cao Zhengyong can obviously hear from the sound of horses' hooves to ride more than 20 horses, Yongkang City has at least hundreds of soldiers, with the city wall absolutely has the power of a battle, even if the city gate is opened, Mongolian rangers may not dare to rush into the city. In addition to not being willing to take risks for no reason, the more important reason is the long-term illness of the Southern Song Dynasty bureaucracy - internal discord and mutual attacks, as long as the officials of different factions do not stab themselves in the back and fall into the well, it is okay, as for sacrificing their lives to save you? Don't even think about it. Due to the fact that the war destroyed the ruling order of the Southern Song Dynasty in western Sichuan, although this Yongkang County was nominally under the jurisdiction of Chongqing Prefecture, Yongkang County Ling Xie Jinyong was actually a close confidant of Yao Shi'an, the defender of Genting City, and never took the Pan control of Chongqing Mansion in his eyes.

Seeing that the sound of the Mongols' horses' hooves was getting closer and closer, Li Shuang gritted his teeth and stomped his feet, so he had to lead his men along the moat to the mountains behind the left of Yongkang City. On the right side of Yongkang City is the wide Weijiang River, and everyone is running to the mountain forest on the left, which is only more than 200 meters away from the city gate.

The Mongol rangers came very quickly, from appearing in front of the defenders of Yongkang Village to shooting their bows and arrows in a short time, they shouted and shouted while borrowing horsepower to shoot arrows at the defenders in the city, and the Song army in the city also responded with a few sparse arrows. Seeing that the city gate was closed and there was no chance to take advantage of it, the Mongolian rangers turned to the Song army fleeing along the side of the mountain to chase after them, but fortunately, when the Mongolian army drew their bows and shot, Ouyang Xuan and others had already drilled into the mountains and woods along the path, the forest was deep and dense, and the feather arrows were blocked by the trees and were not shot. Everyone continued to bow and climb the mountainside, and only more than ten meters forward encountered an unclimbable cliff blocking the way, so they had to continue to turn to the left mountain forest. At this time, the Mongol rangers had reached the bottom of the mountain, but did not go up the mountain, they pursued at the foot of the mountain in the parallel direction where the Song army walked, and followed on their horses and fired arrows into the mountain. Although the grass was deep and dense, and the weather was late, the Mongolian army only fired arrows indiscriminately at the sound of the sound, but two soldiers were still shot, and they were immediately carried forward. Fortunately, after a short time, the Mongolian rangers stopped pursuing when they saw that it was too dark, but Li Shuang still did not dare to stop, and only stopped in a sparsely grassy hillside clearing until the sky was completely dark.
