The 100,000 Han troops who disappeared, Huyan Leopard really had a headache, and released all the Tanma camps, and now there is no news coming back. There are no anomalies in the passes along the Great Wall. This made Huyan Leopard even more incredible, the 100,000 army disappeared in this shallow mountain, it was indeed incredible, if Ouyang Xuan did this, Huyan Leopard did not doubt it at all. Because he could always see Ouyang Xuan go out with five thousand personal soldiers, and when he came back, he had an aura thousands of miles away. But if the Han army can do it, Huyan Leopard will not believe it.

Half a month later, the captain of the Tanma School reported that more than a dozen Tanma had not returned so far, and the direction of the exploration was the Luanshui River Valley outside the Great Wall. Huyan Leopard hurriedly found a map to carefully study and judge the Luanshui River Valley, the Luanshui Pass of the Great Wall is located on the Luanshui River Valley, the Luanshui passes through the pass, the Great Wall along the shallow mountainous area from Juyong Pass bypassing the north side of Yuyang, crossing the Luanshui to the east. When he didn't know why, Huyan Leopard ordered people to find local people who were familiar with the Luanshui River Valley and asked them to describe the situation in Luanshui in detail.

Originally, Luanshui went through several diversions to form today's river valley, and Luanshui Pass is located in the deepest part of Luanshui, and people can swim through the pass with a bamboo tube to breathe enough. After listening to the description, Huyan Leopard also suddenly became enlightened. Immediately ordered Luanshui Pass to quickly arrange mines, and the muzzles of the guns were all aimed at the rear side of the trail, and the situation around Luanshui was closely monitored. But when I think of 100,000 people having to swim through the water, I don't understand how to think about it. Two days later, news came from Luanshui Pass, the mines had been arranged, but the muzzle of the cannon had not been adjusted, and several soldiers were sent along the river to check, and there was no sign of anyone swimming through the pass within 100 miles on the north side of the Great Wall, and there was no trace of anyone within 10 miles on the south side.

This made Huyan Leopard even more confused, so he had to order strict precautions everywhere. Find a messenger (signal soldier) and "quickly report the situation here to Li Shangshu and ask for reinforcements from the mountain army."

The summer heat and the heat in his heart made Huyan Leopard's whole body soaked with sweat, and the sweat fell to the ground dripping. Listening to the sound of sweat falling to the ground, Huyan Leopard suddenly thought of the thirty-mile-long cave with a dark river flowing in the valley of Zuoxianwang's camp during the conquest of the Xiongnu, and thought of the tragic scene, which couldn't help but make Huyan Leopard turn from hot sweat to cold sweat.

Hurry up and ask people to find herders, hunters, guides, and merchants who are familiar with the mountains. Two days later, five hunters who were most familiar with the mountainous area were found. Huyan Leopard was not polite, and directly stated the purpose of inviting them, whether there was a cave or a secret passage connecting the inside and outside of the Great Wall. Several hunters thought for a long time, and the others shook their heads, only an elderly hunter got up and bowed his hand and said: "General Hui, the grass people once smelled from the mouth of the elders that the original Luanshui once flowed into a cave twenty-five miles northwest of the current Luanshui Pass, and the sound of the water was huge after entering the cave, like a dragon's groan, and they all called this cave the Longyin Cave. There is a waterfall in the southwest of Luanshui Pass 30 miles away, fall into the water more than 10 zhang, after years without stopping, all call this hole a mountain water cave. The cave is full of fog and water all the year round, and wild beasts live in groups, and no one dares to enter the cave to check. It's just that after Emperor Gao moved ten years, the mountain stone and the road of Luanshui into the cave were intercepted from a hundred miles away, and Luanshui was diverted several times to form today's Luanshui. Longyin Cave lost its sound because of the lack of water, and the locals once said that it was Long Bin's ascension to heaven, which was related to the matter of King Yan, and at that time he beheaded a hundred people because of this. Three years later, the waterfall also disappeared, the entrance of the cave was dry as usual, and the small people also lived with the cave for a few days. It's just that the cave is too deep, and I didn't dare to explore it deeply. I wonder if this remark of the grass people can help the general? ”。

"Oh? There is also this matter, does the old man know the location of Longyin Cave? ”。“ Back to the general, the grass people went there when they were children, and now they vaguely remember it." A young hunter got up and said: "General Hui, the grass people know where this cave is, and they have also explored this hole, from the entrance of the Longyin Cave into the hole for two miles, it is a vertical hole, straight down more than 30 zhang, the grass people have climbed the rope to go down to the bottom to explore, it is a pool, the water is waist-deep. The bottom of the cave is very broad, the cave wall has traces of artificial carving, the hole is more than 50 zhang high, after going to the water, it is enough to accommodate tens of thousands of people to hide. Due to the fact that there are too many branch caves and insufficient torches, the grass people have not explored deeply, and they do not know whether they can lead to the mountain caves. The grass people can lead the way for the army".

"Okay, good, come here, reward the two of you with a thousand gold coins each. I also ask the little brother to take his army to explore the horses." "The Emperor Taishang once taught us that it is our duty to serve the country. The general rewarded us with unbearable work and a gesture. If you say kindness, I am afraid that the emperor will be hurt." The old man also got up and said: "What the little brother said is very true, we can have a rich life today, it is all given by the emperor and the army, if you receive the reward, it will be very tormenting to us."

"Where the words come from, the two of them have made a speech. It can make our army lose tens of thousands of people, and there is no reason not to reward it. Even if the emperor is here, it is also a heavy reward. Come and reward". Outside the door, two deacons and soldiers each held a plate in their hands and brought it to the two of them. "This is a reward for all the soldiers, and you must accept it." "Alas, it's not about killing us." The old man muttered while shirking. In the end, the two of them only took a gold coin as a souvenir when they took Tanma out of the camp, and the others were sent back to the Chinese army's tent by Tanma. Seeing that the generals and colonels in the tent were all enthusiastic, they vowed to kill the enemy and defend the current prosperous era. "Ben Jiang now knows that what the Emperor Tai has done over the years is so magnificent and so deeply rooted in the hearts of the people. Let me wait how not to fight to the death to be loyal, thinking that my father and fellow villagers", Huyan Leopard said in a somewhat hoarse voice.

Two days later, Tanma reported: There were more than 50,000 Han troops disguised as Huaxia Army stationed within a few miles outside Longyin Cave, and the released Tanma disguised itself drove away the villagers within ten miles, so that its whereabouts are still unknown. After listening to the report of the Tanma, Huyan Leopard's hanging heart finally fell to the ground. Drawing 50,000 from the 100,000 reserves, led by the deputy general, they surrounded the cave in a dotted shape thirty miles away, and closely monitored the movements of the Han army. After giving the order, Huyan Leopard wiped the sweat from his forehead, returned to the room, and slept well.

Three days later, the horse returned that the number of troops outside the cave had increased to more than 70,000, and soldiers were coming out of the cave day and night. Now that he knows the location of the 100,000 Han troops who disappeared, Huyan Leopard has no worries. The herald ordered to surround the troops, and once the disguised Han army made any abnormal moves, they would immediately attack with all their might. He Chan took 100,000 Qiang mountain troops to come by train as promised, Huyan Leopard reported the situation of the Han army outside the cave and He Toad, after two discussions, finally He Toad led the mountain army to replace the central army to continue to monitor and besiege the Han army, and annihilated in one fell swoop after all of them came out of the cave.

Huyan Leopard, who put down his burden, drank tea and explored the sky with the generals and colonels on the tower of Juyong Pass, and joked with the soldiers on duty around him from time to time, so he was leisurely and comfortable, and he saw that the Han army outside Juyong Pass was also inexplicable.

The Han army outside the gate is still free from battle, but Lu Duan in the camp is like a pins and needles. Before leaving, I found several people and officials who had lived in Shanggu and Yuyang to understand the detailed geomorphological characteristics of the local area, and also modeled one on Ouyang Xuan's sand table, and pondered it repeatedly for several days. There was no way to conquer Shanggu and other places, until one night a man who claimed to be from Yunmeng Mountain handed over a letter and left in a hurry, in which he mentioned a secret cave old waterway, connecting the inside and outside of Luanshui Pass, which could be cured by surprise, and provided a detailed map and plan in the cave.

The army led to Guangyang, according to the plan, divided the troops into two roads, and according to the map, found the cave. After cleaning up more than a dozen Chinese army scouts, the whole army entered the cave in batches. In the cave, there is a complete old armor of the Chinese army, change the armor according to the plan, and station the soldiers at the waterhole in the cave, and drink water day and night out of the hole. It took more than ten days to get the water in the pond exhausted, and the first soldiers climbed the rock in the vertical hole and chiseled out steps for the follow-up soldiers to climb, which took several days to complete. At present, 80,000 soldiers have been assembled in Guanbei, and all of them will be assembled in two days. It's just that now they are attacking from all sides, and they have suffered crushing defeats in all three places, only here they are still standing still, Liu Che has given a death order, and he will attack immediately, and if he does not win, he will move the three clans. Liu Che's order had to be carried out, but the sneak attack army was not yet in place how to attack. That terrible cannon was enough to put the 200,000 army in danger of annihilation. Lu Duan, who is sitting on pins and needles, is now not attacking, nor is he not attacking. Looking at the map repeatedly, he ordered the whole army to divide into two routes, one to attack Juyong Pass in Shanggu, and the other to feint Gubei Pass on the north side of Yuyang, in an effort to delay for two days.

Two days later, the sneak attack army in the north of the Great Wall sent a letter back, which had been assembled and was changing clothes, preparing to attack Juyong Pass. Lu Duan was extremely excited, and immediately ordered to take the lead in attacking from Gubei Pass. In the second half of the year, he attacked from both sides of Juyong Pass and won Shanggu in one fell swoop. It's just that the idea is beautiful, and the reality is skinny. Before the Han army, which had finished changing its equipment at the entrance of the cave, was covered by artillery fire from three sides. After several rounds of artillery fire covered, He Toad took the lead in leading the mountain cavalry army to attack the Han army from three sides.

Lu Duan, who was in front of Juyong Pass, almost dropped his jaw after hearing the sound of artillery fire behind the pass, knowing that this time it was a complete failure. The Han soldiers were scattered and launched an attack on Juyong Pass, the failure was doomed, the powerful crossbow arrows on the city were inclined down like raindrops, which were also mixed with the terrifying giant crossbow arrows, a powerful giant crossbow that was several times more powerful than the three-bed bow crossbow, made of alloy provided by the Duliba people, using a combination of levers and pulleys to wind the winding, two people can complete the winding. Each time three metal crossbow arrows with unique shapes, the shaft can be filled with explosives 1 charge, pull the fuse, when winding, as long as the hair rope is clamped on the rear crossbow string, the fuse can be pulled when fired. The power of the explosion is equivalent to ten grenades. In order to prevent the crossbow arrow from being pulled and losing power, the front and rear three-string device is specially set, the last string pull range is short, the two front string pull range is long, and the whole crossbow arrow is running in a fixed arrow groove, which ensures the stability of the range and the stability of the crossbow arrow in the air. This alloy production method is only known to Ouyang Xuan and some of his own soldiers, as well as Duliba people.

Twenty pairs of crossbow arrows of such power were lined up on the Great Wall of Juyongguan, which made the Han army besieging the city miserable, and before they reached the city, they were killed and wounded countless times. From beginning to end, he did not break through the line of attack with a bow and arrow at a hundred paces. Plus artillery fire on the batteries and regular 60 artillery bombardment. In front of Juyong Pass and Gubei Pass, it instantly became the surface of the moon. Corpses were strewn all over the field, and rivers of blood flowed like rivers. Looking at such a tragic scene, Lu Duan was really speechless, and led his own soldiers to launch the final charge, and the final outcome was that a giant crossbow arrow passed through his body and exploded to pieces.

There was little suspense in the battle at the entrance of the cave, and the Qiang cavalry and foot soldiers alternately covered the charge, which soon broke the will of the Han army and surrendered one after another. He Chan ordered the cavalry to escort the surrendered Han army back to Shanggu for resettlement, and he took 50,000 foot soldiers out of the cave in batches. The battalion launched an attack on the fleeing Han army, and won a lot of losses, with tens of thousands of casualties. Just after noon, the battlefield was quiet again. The Qiang soldiers who attacked from the rear escorted the prisoners of war back to the pass, and they kept picking up the lightly wounded on the way, and could only give them a happy break for the seriously wounded. Of Lu Duan's army of 300,000, less than 2,000 eventually fled back to Guangyang.

As soon as the battle here ended, Ouyang Hong of Xia Gu received a battle report and won all four battles. The leading generals of the Han army were all killed except for Wang Li, and the soldiers of the Huaxia Army in the fourth battle lost 5,000 people and wounded 10,000. Ouyang Hong issued a will for the bereavement and reward of the fallen soldiers, and also issued a will for the pacification of the wounded soldiers. At the same time, the Han court sent negotiators, and the two sides began several months of arduous negotiations in Yanmen, and finally reached an agreement. The Huaxia Kingdom returned to the border line before the last Sino-Han War, and the Han court compensated for the losses caused by the two invasions of Huaxia, doubling the amount of tribute each year.

Liu Che was extremely depressed after receiving the news of the failure of the attack of the Ideas, and he could never have imagined that the war, which had been carefully prepared for several years, would still end in failure. Now that the source of troops has been lost, let alone Seiko, even the ability to protect itself is not enough. It had to make concessions and recognize the Han court as a vassal state of China. Now all hopes are pinned on the cronies sent to study in Huaxia, hoping that they will come back and wait to give Hanting something new. The Confucian scholars in the DPRK and China did not care about the failure of this counterattack, but accepted it calmly, and even put forward many unbelievable conditions to ensure that Confucianism could enter China. Again, the ideal is very full, the reality is very skinny, Huaxia has begun to build the Great Wall in the south, and all Confucian classics and Confucian scholars are refused to enter Huaxia. The Confucian scholars were very dissatisfied with Huaxia's attitude, and once again encouraged Liu Che to make military preparations, continue to train soldiers, and prepare for another war. Ouyang Xuan, who lived a reclusive life in the Dawan Valley, learned about the battle situation, and repaired the book to the prince and Li Mu, preparing for the next counterattack against the Han court. With the appearance of a mysterious figure, Liu Che once again kicked off the prelude to preparing for war.
