For several days, the two sides continued to fight fiercely, and Nanyi's offensive became more and more fierce. With the will of steel and unyielding spirit, the Lingnan Bian Army defeated dozens of attacks by the enemy.

The two sides invested so much, the frequency of siege was frequent, and the intensity was very rare in the history of Nan Zhao. In this high-intensity tug-of-war, nearly half of Nanyi had suffered casualties, and the Lingnan border army was also seriously injured.

But war is so cruel, with a lowly and powerful man. In the eyes of the commander, the soldiers are just a set of numbers, as humble as ants.

At dusk that day, the setting sun fell on the earth, and the lush hills had already been dyed dark red. Under the gate of Zhennan Pass, the accumulated corpses had reached half the height of the wall, and the smell of blood filled the sky, like hell. The slight breeze howled, as if to awaken the dead soul.

Next to a fire above the wall in the northern section, Qingyan was roasting a hard steamed bun. As his butt moved, the blood stains on his body fell down in pieces.

"It starts from the first day of the siege. Today is the fourth day."

"Yes, I've been with it for four days." Dong Yan lay beside Qingyan, answering weakly.

"Did Nanyi put life and death aside in this way in the offensives of previous years?" Qingyan flipped the steamed buns on the branches.

Dong Qi still said in the same tone, "It's strange that although the monkeys in Nanyi were very cruel in previous years, they have never been so fierce and fearless. As long as there are more than a thousand casualties, they will call the gold and withdraw their troops. However, in the past few days, there are only five thousand casualties and no gold and repair them. Even after the repair, they will pounce again."

"If something goes wrong, there will be a demon. Nanyi is absolutely unusual. Use your brain to think about it carefully and think about what is missing."

"Brother, don't make things difficult for me. I'm not as good as you and Zhao Jing in my mind. You should think about these things."

Qingyan sighed and handed the baked steamed bun to the person beside him who was leaning against the battlements. This person was the one who had accompanied Qingyan before. In the past few days, he was the only one left in ten people.

"Brother Ma Yue, you haven't eaten for a long time, you can take this one first."

Ma Yue was not pretentious, and he took the steamed bun and started to chew it. During this period, he accidentally pulled the wound on his thigh and grinned in pain.

Qingyan Xiaoxiao didn't speak, then looked at the fire and fell into deep thought.

Nanyi tried his best to solve the problem, but there were only two goals. One was to attack in real life, and simply wanted to force the pass by the advantage of numbers and exchange life for life without remembering casualties. The second was to attack feint, which used the maximum attention of the Lingnan Army to conceal the purpose behind it.

The first point has made the Lingnan border army a little unbearable. If it is the second point, what exactly does the enemy want to hide?

Qingyan's brain rotated rapidly, carefully passing Bai Yi's experience and Su Ju's teachings.

"No matter what you conceal, it is aimed at capturing Zhennan Pass..."

Dong Feng kicked Qingyan and asked, "What are you muttering?"

"Mr. Su said that there are many ways to attack the city, but there are only two aspects: light and dark, light and dark..."

Looking at the fire in front of him, Qingyan placed himself at Du Ming's perspective and deduced various methods.

"Dong Yan!"

"Ah, ah??" Dong Xian suddenly heard Qingyan's roar and rolled on the ground several times in fear.

"Go and get the map of the ten miles of Zhangzhen Nanguan. It must be extremely detailed, go quickly!"

Although Dong Qi didn't understand what was going on, he believed in his good brother unconditionally. Seeing that his face was extremely serious, he ran away.

After half a cup of tea, Dong Yan rushed back panting. In addition to bringing back the map, he also brought Dong Polu.

Qingyan did not pretentiously, led the two into the wardrobe, and then ordered Ma Yue, "Brother Ma Yue, no one is allowed to appear within two meters of the wardrobe, remember! Remember!"

Putting the map on the wooden table, Qingyan picked up the oil lamp and observed it carefully. Seeing that the Dong family did not disturb him, he even controlled his breathing very lightly.

After carefully observing the incense stick for half a long time, Qingyan stood up and exhaled a breath of turbidity.

"Brother, what did you find?"

Qingyan said in a deep voice: "Prince, Brother Dong, the frequency and intensity of the enemy's siege in the past few days are absolutely unusual. The casualties are so tragic that they have not been repaired for a few days, and the offensive is more and more fierce every time, so I suspect there is something strange here."

"If you find something, just say it bluntly, even guessing it is okay." Dong Polu's face was as usual.

"I think the enemy's offensive is just a concealment of the plot behind it." Qingyan pointed to the map, "Prince, please see, Zhennan Pass is built along the mountain, winding east and west. Except for occupying most of the houses, the relatively empty area only has the markets in Xixiaochang and Guanbei."

"Because the north and south are rugged and difficult to move around, the enemy wants to send people down the mountain, and it is too small to achieve the effect. If it is feasible, Nanyi has been used many years ago. And if it doesn't work on the ground, it is a possibility."

"Are you talking about authenticity?" Dong Polu shook his head slowly, "Your idea is feasible, but you don't know that the stones underground in Lingnan are extremely hard, and it's not a matter of a day or a night to dig authenticity..."

Dong Polu's words came to an abrupt end, and his pupils shrank sharply and looked at Qingyan.

"It seems that the prince had thought that since the sky-blocking force could transport so much food to Lingnan, it can be seen that its ability was. If this force had dug the tunnel not far from the city wall a long time ago, and then dig it into the hinterland of Guanzhong with the cover of the siege, it would make sense."

"Yes, when siege, killing the sky, no one could hear the sound of a chisel. If it was as you expected, the Nanyi monkey's crazy behavior these days was to remove the firewood from the cauldron!"

Qingyan pointed at a place with his hand, "The space of the house is too small and easy to be discovered. The long journey of the market in Guanbei will greatly reduce the progress, so there is only one exit at that tunnel."

"Kansai Schoolyard!"

"The school ground has now been temporarily changed to an injured camp. There are not only a large number of wounded people inside, but almost all the female members of the border army are also in the injured camp. If the enemy army is like a magic weapon and slaughtered the injured camp, this will be a very heavy blow to the morale of the border army. If it is serious, it will lose its fighting spirit and lead to a mountain of defeat."

"No need to say anything more. I would rather believe that it is not true. Qingyan, you just want to say how many people are needed."

"Two thousand people! They must be the elite among the elites in the border army. Each person is equipped with a hard bow, a strong crossbow, and fifty arrows..."

-------------------------(I'm a dividing line)

Nanyi Daying is built on a huge hill with a high terrain. It has four trenches and trenches and arrow towers, which are easy to defend but difficult to attack.

Behind the hills, that is, the west end of the camp, there is a rock that is not eye-catching, but there have been 5,000 elite troops in Nanyi before the rocks.

"Brothers, everyone standing here is my Nanyi warriors. I believe everyone is well-known in the army. Today I will gather you here for nothing, but give you a great contribution." Du Ming stood beside the rocks and shouted loudly.

"You! You are about to become the vanguard of breaking through Zhennan Pass and the first person to attack Nanzhao's land." After Du Ming said that, he waved his hand immediately.

The personal soldiers beside him understood and quickly moved the rocks away one by one, revealing a huge black hole about one foot.

"This is the entrance to your victory. I hope you will live up to the king's trust, return triumphantly and set off!"

With a command, generals at all levels led 5,000 soldiers into the entrance of the cave. Not long after, five thousand people disappeared at the entrance of the cave.

Du Ming turned around and ordered again, "Surprise the city at the hour of Hai!"

-------------------------(I'm a dividing line)

The sky is covered with clouds tonight, and the bright moonlight and stars cannot be seen, but the countless torches raised outside the pass are as bright as day.

Dong Polu stood directly above the city gate with his hands behind his back, staring coldly.

"The three armies are ordered to prepare to defend the enemy, and all the equipment to defend the city will not be saved. If I let the king know the last drop of tincture oil or which piece of marble appears, I will whip it from top to bottom twenty!"

As if responding to Dong Polu's words, the enemy launched an offensive at this time. Depending on the situation, the enemy's troops were unreserved this time and all their troops were placed a hundred feet outside the pass.

Night battle has many difficulties for both offense and defense, but both are very brave and soon entered hand-to-hand combat.

Dong Polu walked around the wall with a large halberd in his hand, trying his best to maintain the front line. On the back of the wall, the soldiers on the steps were waiting quietly. Although they were crowded, they were still neat. The armor was as dark as ink, and they appeared and disappeared in the dark night. The guns and swords were like forests, and they were unwavering to be determined to die. Whenever the wall was issued, a team of soldiers would supplement them.

When the two sides fought fiercely at the Guan Wall, the wounded camp two miles east of the Guan Wall was surprisingly quiet.

Several crows were standing on a straw shed, and suddenly flew away by the strange noises under them. They saw a pile of tall grass in the shed moving, and then slowly walked out of it. This person was very cautious and squatted on the ground and carefully observed the surroundings. Seeing that there were no sentries around, he patted the straw behind him.

One, ten, hundreds. Groups of Nanyi soldiers gathered outside this hidden straw shed.

When the number of people reached more than 3,000, these people suddenly felt countless sounds of breaking through the air coming from all around.

"There is an ambush! Be careful!" A general shouted loudly, but the rain of arrows around seemed endless, and every breath would fall down a hundred people.

The general knew that the plan was exposed, but thousands of people returned along the tunnel in a short time was like a fool. Then Gangya clenched and shouted: "It's time for the conferred marquis to be the general! Brothers, kill me!"

These elite Nanyi soldiers thought that tonight was a great opportunity to make achievements, but unexpectedly, they were such a desperate result, so they could only rush out with the general.

Before they could break out, the general vaguely discovered the army on the south side of the Lingnan Army. At this time, they were forming a long snake formation. Two soldiers squatted forward and stood backward, shooting waves of arrows towards their side.

"The enemy's number is only more than one thousand. Brothers, follow me to kill him!" The general blocked the two eagle feather arrows and ordered again.

After rushing out dozens of steps, the generals from the Lingnan border threw the longbow forward, raised the powerful crossbow from behind, and aimed at him.

The Nanyi general's steps slowly lowered and he looked at the other party's crossbow formation calmly.

"well....."

A sigh became the last voice of the general in the world.

Countless crossbow arrows tilted with anger, and the soldiers in Nanyi suddenly accelerated their fall, as if the rice harvested in autumn was ruthlessly harvested.

The last enemy army at the moment fell down, and Qingyan ordered in a deep voice: "Put the forage at the tunnel exit and burn it, fan it hard, remember that as long as the thick smoke, the more the better!"

Qingyan didn't know how many enemy troops were fleeing in the tunnel, but he thought that the number of people would definitely not be small. The key to this ambush was to annihilate the enemy's vitality. Even though he felt a little unbearable, Qingyan still issued an order without hesitation.
