Cao Ren?

Do you really dare to come?

Shen Chen sneered twice in his heart, but he didn't know that he had already prepared too many things for today.

Looking at Cao Ren's figure below, Shen Chen sneered: "Who am I, it turned out to be Cao Ren, a one-eared thief, the blood debt of hundreds of relatives gathered in Zhangyang, I have to settle it with you today." ”

One-eared thief?

Cao Ren's eyes turned red in an instant, and he pointed to Qiong Lang in the distance and said, "Kill him." ”

"General, there is no entrance to that arrow tower."

A low-level officer who had followed Cao Yong before hurriedly stepped forward and said, "I have nowhere to start." ”

"No entrance?"

Cao Ren was stunned and said, "How is it possible? ”

Above, Shen Chen continued to hold the loudspeaker and said, "Cao Ren, do you want to find the entrance, tell you that the entrance is underground, and you have the ability to dig in." ”

"General, there are signs of loosening on the ground over there, and it has been buried by some dry grass branches."

Just as a soldier discovered the hidden entrance.

Cao Ren is not stupid, he knows that since the other party dares to tell him that the entrance is underground, he has nothing to fear, but at this moment, he is already riding a tiger, coming in the name of revenge, and losing his brother Cao Yong, he is afraid that he will lose face when he goes back.

Therefore, he could only bite the bullet and say: "Order the army to search for other entrances first, and then let the dead soldiers go in and have a look." ”

"Yui."

The officers then picked out the death squads.

Ancient bows, crossbows, arrows and armor were very important strategic reserve resources, and the stock of arrows in Huangmen Pavilion was not much, and it was impossible to rely on bows and arrows to eliminate Cao Ren's army.

So from the very beginning, Shen Chen didn't simply rely on Qiong Cage to deal with Cao Renjun, and the real killer weapon was still underground.

Cao Ren still had more than 4,000 horses left, and in addition to the 500 people who responded from outside the valley, about 3,000 people came in and conducted a carpet search of the valley.

Soon, they eventually found four entrances, in four directions, one in the south, east, and west.

The quartermaster prepared torches for them, and for the army to travel, a fire sickle and a certain amount of fish paste grease were necessary, but not in very many quantities, and were filled with water bladders, that is, pig bladders, which could be used for ignition and lighting at critical moments.

There were a large number of branches around the entrance to cover the entrance, and there were planks at the entrance, which were cut down by the soldiers, chopped into sticks, sprinkled with a little grease, and lit with a fire sickle to turn into torches.

The members of the death squad took torches and peeked in at the entrance, and the inside was black, like a giant beast's open jaw, as if it was about to devour them.

Many soldiers swallowed a mouthful of saliva, everyone knew that entering was a life of nine deaths, but Cao's military law was harsh, and most of them were Qingzhou Yellow Turbans that Cao Cao surrendered back then, and their families were controlled by Cao Cao and treated as Tuntian military households.

If you resist the order, not only will you suffer, but your family will also be punished. Therefore, even knowing that the road ahead was very dangerous, the members of the death squad could only bite the bullet and start to go down.

Soon everyone rushed in, and the first group was pure death, and there were not many people who entered, only more than thirty people, and they gathered half a foot in front and back, each with torches in their hands to explore the road ahead.

After entering, the imaginary ambush did not seem to be, only a very long road, like an underground corridor, flanked by solid rammed earth walls, and the group walked almost forty or fifty zhang away, and the road ahead was still not in sight.

"Strange, what is this hole for?"

As a soldier walked, he was surprised to notice a small hole in the wall on the right.

"It's not good, get out of here!"

The thirty-odd men were led by three chiefs and a captain, and the captain was so well-informed that he hurriedly beckoned the soldiers to retreat.

It turned out that this person had been a soldier in a secret army under Cao Cao, and had followed a Faqiu Zhonglang to dig a mausoleum in Pishan, and had seen such holes in the walls in the underground palace.

Of the more than 300 people who went down to the field that time, only about 80 escaped with gold, silver, and jewelry.

And the general of Faqiu Zhonglang also died in it, and there was no leader, and since then, the team has been disbanded, and the soldier has been transferred to other posts, and now he is under Cao Ren as the captain.

Seeing this kind of corridor wall again now suddenly reminded him of that bad experience at the beginning, and hurriedly beckoned everyone to retreat.

But it was too late.

Shen Chen had actually read the Mojia Trick and the Book of Luban, which were not lost in the Han Dynasty, including Zhuge Liang's construction of wooden oxen and flowing horses, which were also made with reference to these books.

In addition, he was a design dog before he crossed, and he had seen a lot of tunnel design and architectural design before, so he had some experience in designing underground passages.

The tunnel hole is indeed a kind of mechanism, but it is not the kind of crossbow bolt mechanism recorded in the mechanism technique, but a spear mechanism.

Almost after the Cao soldiers noticed that something was wrong, an iron fence suddenly moved horizontally from the wall behind them, blocking their retreat.

This fence gate is a design that actually appeared in the tunnel warfare in history, and since there is no welder equipment, the door is spliced together from fired iron rods that are still in the hot and red stage.

On weekdays, it hides in the cracks of the walls and is covered with rammed earth. As soon as the need arises, people push the fence gates behind the walls, blocking the front and back roads.

As soon as the road was blocked, a large number of spears immediately appeared in the hole.

Immediately, the screams were endless.

Sharp spears stabbed into the body, and the sound of popping into the flesh continued, and soon the blood flowed profusely, and the passage was full of corpses, and the blood seeped out along the drainage channels of the rammed earth.

After about two or three minutes, as the soldiers of the Yellow Gate Pavilion on both sides of the wall continued to poke back and forth with spears, the voices in the passage became weaker and weaker, and all the Cao soldiers died in the trap.

There was a second group of troops in the rear, and seeing the iron fence gate blocking them from the front team, and then being slaughtered by spears, they were terrified for a while, and fled out in a panic, only hating their parents for giving birth to two less legs.

"Will ..... Checkmate. ”

The officer who escaped from it ran to Cao Ren's side in a row, and said in horror: "There is a mechanism below. ”

Cao Ren said impatiently: "There must be an organ, what is the organ, can you see it clearly?" ”

The officer's palpitations did not fade, and his face turned pale and said: "There are holes in the wall, once you step into the mechanism, an iron door will stick out of the wall and lock it, and a spear will stick out of the hole. ”

Iron gates block the road, holes pierce spears?

Cao Ren pondered for a moment and asked, "Have you written down the location of the iron gate?" ”

"Got it."

"Then this mechanism is easy to crack, dig a pit at the location of the iron gate, and then embed a long boulder into the pit, when the iron gate is pushed out, just leave two people to push it back, and the rest of the people use shields to block the wall, or stab it with spears, or cut off the shaft of the spear with knives, understand?"

"Understood."

"Go ahead."

"Yui."

The officer received the order and immediately began to do what Cao Ren had arranged.

I have to say that although Cao Ren was provoked by Shen Chen, he still retained his sanity, and he was very smart and good at thinking, so he quickly thought of a solution.

Since the iron door was pushed out of the wall, they could also push it back, and the hole protruded with a spear, and they could also use the spear to stab it.

And the spear is only made of iron, and the shaft of the spear is wood, so they can defend themselves with a shield, and when the spear comes out, they can cut off the shaft with a knife, which can also damage the enemy's weapon.

Cao Ren didn't believe that just with his strength as a Huangmen Pavilion township, he could still have a large number of weapons and equipment?

In fact, Cao Ren was right.

In the final analysis, even if Shen Chen tried to find a way to strengthen the Yellow Gate Pavilion, their size was destined to not have too many weapons and equipment.

More than 10,000 arrows, all of which were obtained by racking their brains and trying to get them by all means. Some were made by themselves, some were collected from the Yellow Turban Army, and some were secretly bought through Zhou Lin and other big businessmen.

You must know that it is a capital crime to be discovered, whether it is Liu Zhang or Liu Biao, it is strictly forbidden for this kind of strategic materials to flow out, such as wooden poles and feathers used for arrows, which are included in the contraband.

Therefore, whether it is arrows or armor, there are very few Huangmen Pavilions, not because there is no iron to make arrows, but because there is a lack of wooden poles and feathers specially used for making arrows.

However, normal knives and spears were well stocked, because the Han Dynasty did not prohibit the common people from owning weapons, so it was very common for the common people to wear swords, and in peacetime, they only needed to spend 600 pieces of five baht to buy a wrought iron sword.

After Cao Ren gave the order, the officer quickly followed his instructions and sent a new team of men and horses down the cave, and these soldiers blocked the position of the iron gate with stones and shields to block the hole with shields.

The soldiers of the Yellow Gate Pavilion repeated their old tricks and continued to stab with spears. As a result, he was either blocked by a shield, or the wooden pole was cut off by Cao Jun's soldiers, and he was even stabbed back, injuring several brothers.

Seeing that the situation was not good, Deng Zhao, who was in charge of the command, immediately issued an order: "Withdraw, go to the second pass." ”

So the soldiers of the Yellow Gate Pavilion retreated one after another.

The soldiers of the Cao army finally passed this level, and after everyone rushed in, they found that the front was still an iron gate, but no one pushed it behind, and at this moment they moved away with a push and pull inside.

In front of them were two passages to the left and right, which led to the left and right walls of the corridor from which they came.

At that time, the soldiers of the Yellow Gate Pavilion were behind these two passages and stabbed them with spears.

The soldiers of the Cao army who came in sent men and horses to the left and right, and after occupying the passage, because they did not know what danger lay ahead, they hesitated and sent someone to report the matter to Cao Renyu.

Knowing that the entrance had been occupied, Cao Ren once again gave the order to let the soldiers enter from the four passage entrances at the same time, blocking all the entrances, and then sending a large team of men and horses to follow behind the dead soldiers and slowly explore forward.

The strength of the dead soldiers in front of him was replenished, and with men and horses behind him, his confidence increased greatly, and he moved forward from the left and right passages again.

And then......

Then the tunnel collapsed.

It turned out that the tunnels leading in from the left and right passages were hollowed out, and wooden planks were laid before, and then earth was sprinkled on the wooden boards.

When Deng Zhao's Huangmen Pavilion soldiers walked through the planks, at first they planned to wait for the pursuers behind them to come, so they immediately removed the planks and let them fall into the trap in the pit.

As a result, he didn't expect the other party to chase after him, so Deng Zhao followed Shen Chen's plan, if the enemy didn't chase him, he would use a saw to cut off most of the plank, leaving only a small half.

The dead soldiers of Cao Jun did not pursue at the first time, and the passage was very long, and the sound of sawing planks was not heard. When the reinforcements arrived, they had already stepped on the planks and rushed forward one by one, waiting for the planks to bear the weight and broke with a bang, and everyone fell into the pit.

The pit was covered with sharp stake barbs, and in an instant, more than a dozen Cao soldiers died in each side of the passage. And in addition to one of the passages dedicated to the old walking of Huangmenting Township, the same is true of the other two passages.

After a while, Cao Ren got the news that the second level was a trap. He asked the soldiers to carry the ladder that was originally intended to attack Huyang City, built the ladder, and finally passed the pit and cave.

However, the tunnels are twisting and turning, and there are still several levels. Behind it were crossbow bolts, boulders rolling, and even poisonous smoke coming out.

Almost except for zongzi, all ancient tomb robbery techniques are used. made the few low-level officers who had participated in the work of General Cao Caofa Qiu Zhonglang and Captain Touching Jin have a sense of déjà vu.

And after paying nearly seven or eight hundred lives, and the pit was full of corpses, the Cao soldiers finally despaired, because the name of the last mechanism was called the Broken Dragon Gate.

On weekdays, these thousands of pounds of boulders are locked with winch chains, and once they are attacked, they are lowered to block the enemy.

The only place where there is no broken dragon gate is an entrance to the west.

This entrance is the one with the least number of mechanisms, because this is the entrance of the Yellow Gate Pavilion on weekdays, so there are no pits, no crossbow and arrow mechanisms, and no broken dragon stones.

No matter how stupid Cao Ren is, he understands that three of the four entrances are fake, and only the one on the west side is real.

Moreover, Shen Chen's location is in the Qionglong on Gaoling Mountain in the west.

Therefore, Cao Ren was ruthless and gave the order to die, allowing the soldiers to kill through the western entrance.

However, although this entrance does not have a broken dragon gate, it has poisonous smoke.

This poisonous smoke was configured by Shen Chen with poison and gunpowder, because he was not a chemical engineering professional, although he used to read the knowledge on the Internet, he knew that the gunpowder formula was one nitrate, two sulfur and three charcoal.

But he didn't know the specific formula ratio, and the gunpowder that came out was a lot of impurities, and the combustion would produce a lot of smoke, more than fireworks.

So he simply mixed a certain amount of arsenic inside, pasted it with mud on the outside, and after igniting it and throwing it out, the mud cracked to produce a large amount of toxic smoke, and the smoke was filled, which would cause huge damage in a small space.

Of course, Shen Chen didn't know that the thing he invented was called a poison smoke ball in the Song Dynasty, but it was more comprehensive, there was more poison in it, and the power produced was also greater.

Fortunately, he used it in the tunnel, threw it out here, immediately sealed the tunnel, and the violent wolf smoke extended out along the passage.

The soldiers of the Cao army choked to death, and the poisoned ones were poisoned, and soon hundreds of casualties were caused.

"General, the poisonous smoke down there is too violent, and the casualties are too great."

The withdrawn officer's face turned pale, and he also smelled a little smoke, and now he only felt dizzy and shaky, and he held on so that he did not faint.

"Damn."

Cao Ren was so angry that he hadn't killed a single enemy so far, but he had lost more than 1,000 people and horses, plus the soldiers and horses that Cao Yong had lost before, and the 5,000 people he brought this time had lost nearly one-third.

"General, withdraw."

Chun Yu admonished: "Since the enemy dares to place poisonous smoke, it means that they have another exit outside the valley, and if they can find the exit, they may be able to trap them." ”

"Shen Chen's fang is really hateful!"

Cao Ren also knew that it was unrealistic to attack, so he could only say with hatred: "Go!" ”

At the sound of the order, the soldiers were relieved and fled to the exit one after another.

At this moment, Shen Chen's face on the cage had become solemn, and he only hated himself now for not having any fish paste and grease.

If anything, pouring a lot of grease from the cage into the mountain road and lighting the fire will inevitably make Cao Ren's army trapped inside and unable to get out.

As soon as the Ganning army arrived, it was to catch turtles in the urn.

Unfortunately, in ancient times, fish paste and grease were not only as important strategic materials as arrows and armor, but also a necessity for people's lives.

The source of fish paste oil is very scarce, and it can only be obtained by refining oil from breeding livestock or hunting game.

It is already scarce, and the price is extremely expensive in the market, even if Huangmen Pavilion is slightly rich, it can only barely ensure that the people can use it, and it is impossible to hoard it at all.

So he could only watch Cao Ren retreat.

However, it was impossible to retreat with his whole body, Shen Chen shouted: "Give me arrows and shoot them!" ”

"Kill!"

Hundreds of archers on the surrounding cage bent their bows and arrows again.

This time, I plan to shoot all at once, almost without reservation.

"Woohoo!"

The arrows began to rain down like money, and soon the arrows were consumed at an astonishing rate.

When some of the soldiers had no arrows to use, they immediately picked up the guys, burrowed into the hole through the passage under the cage, and then followed the labyrinthine tunnel to the exit.

There was actually more than one exit from the tunnel, but at this moment, at the exit near the Shahe River in the north, the floor was opened, and countless Yellow Gate Pavilion soldiers rushed out.

At the beginning of this year, there were only 1,200 soldiers in Huangmenting, and later Gan Ning added 300 people to them as the main force.

These 300 people were born as thieves and were very brave.

There were a total of 1,500 people, about 300 people were archers on the Qiong cage in all directions, and there were more than 1,000 people hiding in the tunnels below, fighting Cao Jun in various tunnels.

After using the tunnels to kill a large number of Cao Jun's living forces, they had to face the fact that Cao Jun was planning to retreat.

If there is no fish paste and grease to seal the road, it can only be filled with human lives.

Therefore, Deng Zhao and Shen Zhen led more than 1,000 soldiers respectively, drilled out from the north and south exits, and rushed towards Cao's army.

Outside the valley, there were still hundreds of Cao Ren's left-behind troops, and when they saw the enemy rushing over at this moment, they immediately formed a formation and prepared to fight without hesitation.

Deng Zhao charged ahead, the tragic situation of the Huangmenting Township Gathering was vivid, and the hatred made him full of fighting spirit, and he broke into the crowd like a jackal, fought hard, and hacked a Cao soldier to death.

Just killed the opponent, and the left and right sides of the ring slashed with swords.

Seeing that Deng Zhao was about to die on the spot, several clansmen around him immediately rushed over to help him block and cover his fight.

In the final analysis, only fierce generals like Lu Bu, Guan Yu, Zhang Fei, and Zhao Yun can charge the battle alone, and ordinary low-level soldiers and officers need to cooperate more.

This kind of cooperation is especially important when there are fewer people and more people.

Fortunately, this time they were more people and fewer people, coupled with close cooperation, each time they attacked one or two Cao soldiers in groups of three or five, killing the five hundred Cao troops who stayed outside the valley and retreated.

The Cao army in the valley is still breaking through, and the stones, arrows, and trees on it are constantly smashing into the mountain road, and the Cao army is trapped in the cage, and it is impossible to jump from the top of the mountain, so he can only choose to brave the rain of arrows from the narrow mountain road to rush out.

Shen Chen stood on top of the cage, his eyes fixed on Cao Ren's position. Due to the full firepower of the Qiong cage, Cao Ren did not dare to risk death to move forward, and could only keep letting the soldiers consume their reserves, so he was still behind at the moment.

The valley is not big, but it is not small. The location of Qionglong is above the surrounding hills, and even if it is blessed by a high tower, it will not be able to shoot that far, so it is still very safe near the center of the valley.

The sound of fighting outside came, and Shen Chen shouted, "One-eared thief, your death is near!" ”

"Shen Chen, one day I want your life!"

Cao Ren roared angrily.

"There's no other time, you're going to die today!"

Shen Chen disturbed his state of mind.

Cao Ren gritted his teeth, his face was bruised, he admitted that he underestimated Shen Chen, but he didn't expect him to build such a terrible trap.

However, he felt that even Shen Chen's people wanted to stop him? The fool is dreaming, and when he escapes, he must let the eldest brother send tens of thousands of elites over to level the entire valley.

"Look, General, Wolf Smoke!"

Zhai Yuan beside him suddenly pointed to Qiong Cage in the distance and said.

Cao Ren hurriedly looked up, and at some point, wolf smoke had risen from the cage.

"Oops, it's a trap."

He immediately came to his senses, it turned out that Gan Ning was not not coming to save Huangmen Ting, but was waiting for a signal from their side.

At that moment, he immediately shouted with red eyes: "Kill, kill, quickly!" ”

"The general has an order, rush out!"

The soldiers immediately went to give the order, so that Chun Yudao, who was in front of the command to open the way, broke out of the encirclement as soon as possible.

However, although the mountain road is not narrow, more than ten meters wide on the left and right, it is already densely covered with corpses, rolling stones, sassal wood, and even lime falling from the sky at this moment.

There are too many obstacles, and the mountain road that is less than 100 meters short has become a Shura field, and countless things in the cage above are smashed down.

The entire Huangmen Pavilion young men went out to fight, but the old and weak women and children were still there, these old men, old women, women and children went into battle, and even Shen Chen's mother, Deng Shi, remembered the hatred of her neighbor Shen Min's family, and threw stones down.

Soon the rolling stone and wooden bows and arrows were used up, and even the ceramic jars, porcelain bowls, porcelain plates, furniture and woodware, as long as they could be thrown down, the power of the clan completely exploded at this time, just for revenge.

"General, they've gone crazy and throw everything down. The ground was littered with ceramic shards, as well as tribulus terrestris and iron nails. ”

Chun Yudao was smashed to the point that his head was bleeding, and he came back from covering his wounds and cried and reported to Cao Ren with a sad face.

There were nails in the Western Han Dynasty, but generally only the coffins of nobles after their death would be nailed, while ordinary people used mortise and tenon structures.

Mainly because the output of iron is too low, the cost of iron nails is high, so it will not be mass-produced, until the Song, Ming and Qing dynasties, iron smelting technology has been greatly improved, and it is widely used.

However, the iron-smelting technology of Huangmenting is an epoch-making technology, and the amount of iron produced is very large, so a large number of iron nails were manufactured for this time.

A large number of nails were thrown into the mountain tunnels, along with porcelain shards and thistles, causing great damage to the Cao soldiers.

Although the soldiers of the Han Dynasty wore a variety of shoes, there were round-toed cloth shoes, wing-tip shoes, duck tongue shoes, straw sandals and so on.

But in the final analysis, they are all single-soled flat shoes, and many of them don't even have soles, they are ordinary straw sandals, and when you step on nails, you can directly pierce the instep.

In this case, the soldiers simply could not rush out.

"Hold your shield above your head and step on the corpse." Cao Ren's face was so dark that he had a bad premonition.

Soon the soldiers did as Cao Ren had ordered, and after paying thousands of casualties, they finally rushed out.

Cao Ren was the last to leave, and at this time, the reserves of the Huangmen Pavilion had been exhausted, so he could only watch him go down the mountain, and when he turned back, he sneered and shouted, "Shen Chen, I won't let you go." ”

However, Shen Chen didn't feel much sad, but shouted with a loudspeaker: "One-eared thief, look outside, do you think you can escape today?" ”

Cao Ren went down the mountain, and there was still a fight outside the valley, at this moment more than 3,000 people came in, only about 2,000 people went out, and outside there were 1,500 people fighting with 500 people, and it was almost over, and the remnants of the army were less than 200 people.

Seeing this scene, Cao Ren was still calm, he was confident that he was fighting head-on, and he could easily defeat his opponent with more than 2,000 horses.

But in the next second, his face froze.

Dust and smoke were billowing in the distance, and Gan Ning's army finally arrived at this time.
