Li Chenghao's 10,000 cavalry went south and arrived at Bole City at dusk. Bole City was originally a supply point for the Xixia army, but now all the food and grass were plundered by the Song army. The army city was empty and there was nothing. This made Li Chenghao very worried. They sent troops urgently and did not carry food and grass. They all rely on Jingzhou and Shunzhou along the way to get supplies. As a result, when they arrived south of Lingzhou, all the sources of supply disappeared. They had not much food and grass in Shunzhou, and they had to return early tomorrow morning at the latest.

"General, we have caught a spy!"

Several soldiers pushed a middle-aged man tied up in front of Li Chenghao. The man knelt down and kowtowed, "God of your life, General, I am not a spy, I am just a runaway slave."

Li Chenghao used his sword to lift his clothes open, and there was indeed a slave brand above his chest. Li Chenghao said coldly: "Are you a Song Slave?"

"The villain is exactly!"

"Then why don't you go south with the others?"

"The villain's wife and children are in Xingqing Mansion. There are no relatives in the Song Dynasty. The villain does not want to go south and wants to return to Xingqing Mansion, so he escaped halfway and begs the general for his life!"

Li Chenghao nodded and said, "You don't have to be afraid. I won't hurt you, but I need to know the details of going south, where did the Baitongshan warehouse, supplies and Song Nu go?"

"They went south and were transported south by sheepskin rafts, and more than 100,000 Song Nu also followed."

"When did it happen?" Li Chenghao asked.

"I started going south two days ago, but I walked slowly. The villain was the last group of Song slaves and escaped from the team at noon today."

Li Chenghao was overjoyed. He only passed here at noon today. He walked for a few dozen miles in half a day. The Grand Canyon of Baimachuan is more than 100 miles long and the cavalry could catch up. He hurriedly asked, "How many Song troops will follow?"

"About a few thousand people!"

"Are they all cavalry?"

The man shook his head, "There are no cavalry, only infantry!"

Li Chenghao was overjoyed and said to the man: "As long as your information is true, I will let you go to Xingqing Mansion later."

The man kowtowed repeatedly, "Thank you for your fulfillment, General!"

Li Chenghao turned around and ordered: "Tell me my order, and the army will speed up and be sure to catch up with the enemy before dawn!"

Ten thousand Iron Cavalry accelerated their speed and chased them along the shallow riverbed towards the canyon.

As night fell, the army arrived at Qinggang Canyon. Li Chenghao looked up at the military camp on the mountain for a moment. It was a dark area with no light and could not see anything clearly. It was not easy to go up the mountain to explore. At least it had to take a detour for more than 40 miles, and they had no time.

Li Chenghao could only bet that there was no army stationed above him. He thought for a while and said to a subordinate: "You lead a hundred brothers to come first. If there is no abnormality, ignite the torch!"

The subordinates received the order and led a hundred cavalry to run into the canyon. About a quarter of an hour later, the light of torches appeared seven or eight miles away, and the hundred cavalry had successfully walked through the Qinggang Gorge Military Village.

Li Chenghao was a little relieved and immediately ordered: "Tell me my order and the army will enter the canyon!"

Ten thousand iron cavalry were launched and rushed into the canyon

Gong Zuwen watched the Western Xia cavalry in the canyon on the mountain. The vast cavalry was as large as 10,000. On the low wall, nine hundred Song troops were ready. They were nothing more than rolling wood, stones and firearms against the Western Xia army. The turret oil was ineffective here. Iron fire thunder and sky-shaking thunder were enough to kill the enemy.

Half of the cavalry had passed, and Gong Zuwen had not ordered an attack yet, and the soldiers were all anxious. At this time, a general whispered to Gong Zuwen: "The cavalry went south at full speed, and I'm afraid they would be able to catch up with the Song people in one day. It would be better to let them retreat."

Gong Zuwen shook his head, "The enemy has no supplies along the way and will not go too far. If there is any blockage in front, the cavalry's front and rear routes will be blocked. Even if this army is not completely wiped out, at least most of the troops will be explained here."

Will there be a blockage ahead? Of course, there will be a blockage. Gong Zuwenling led a side general Yang Du to lead a thousand people to block the tail of Qinggang Gorge more than ten miles away. Unless the enemy does not need to fight horses, they will not be able to cross the fortifications built by the Song army at all.

Gong Zuwen was waiting patiently for the opportunity. At this time, most of the Western Xia army had passed, and the last two thousand people were entering the canyon. The time was finally ripe. Gong Zuwen gave the order, "Shoot!"

The five hundred Song army crossbowmen who had been waiting for a long time fired crossbow arrows at the foot of the mountain at the same time. At the same time, three hundred soldiers threw iron fire thunder into the canyon. The iron fire thunder's fuse was cut short to prevent the firearm from exploding into the water.

The sudden attack caused a chaos in the cavalry. Although the Iron Harrier Cavalry was a heavy armored cavalry and all the people were wearing armor, there were only 3,000 real Iron Harrier Cavalry in Xixia, which were real armored cavalry equipment and armor made of iron pieces.

This is also because Xixia is limited by national strength. It is impossible for 80,000 iron kites to use iron armor. Xixia does not have so many pig iron to make equipment. Except for the three thousand core cavalry that are iron armored equipment, the other 77,000 cavalry all use leather armor. This leather armor can resist ordinary bows and arrows at fifty steps, but it will definitely not withstand the Song army's divine arm crossbow. Even if a shield is used, it will shoot through it together with the shield.

Five hundred divine arm crossbows shot, and more than two hundred soldiers were shot in arrows and screamed and fell from the horse. The sudden change surprised the last two thousand cavalrymen. They instinctively tied the reins and did not dare to move forward rashly. At this moment, three hundred iron fire thunders fell from the air.

Iron Fire Thunder has never been able to become the mainstream of the Song army. Its main weight is too large. An iron fire thunder weighs ten kilograms, which is not much different from the thunder of forty or fifty kilograms. However, its power is much smaller than that of the thunder of the thunder. People would rather use the thunder of the thunder. On the contrary, the mutant brother of the Iron Fire Thunder shines in the defense battle of defending the city.

Today, Gong Zuwen used iron fire thunder. Three hundred iron fire thunders were thrown from the air. Except for dozens of them fell into the water and became dumb thunders, the remaining more than 260 iron fire thunders exploded violently before entering the water.

The shock wave of the iron fire thunder was not big, and it was all due to the splashing iron sheets and iron nails that injured people and horses. For a moment, people in the canyon were overturned, screaming and neighing. The war horses were frightened and turned around and ran wildly. Many soldiers could not control the war horses and fell from the horses. They were ruthlessly trampled by the war horses behind. The casualties of the cavalry were extremely heavy.

This time, the Song army carried the Iron Fire Thunder specially designed for cavalry. Each Iron Fire Thunder was filled with two hundred tiny thorns. While the Iron Fire Thunder exploded, the thorns also covered the canyon riverbed at the same time, which almost cut off the cavalry's retreat.
