Li Su knew that Guan Yu would have to attack Bishui Pass sooner or later, as for whether he would come in person and when he came, he was not sure, but one thing in his opinion Guan Yu would not come immediately, because it was about to be the New Year, and it was not conducive to fighting in such a deep winter, especially it was difficult to attack the city and seize the land, not to mention that Guan Yu was entangled in Luoyang affairs and could not immediately withdraw to fight Bishui Pass, according to this analysis, Bishui Pass should be safe at present, and the war should happen at the beginning of spring, which was expected by Li Su, but Li Su was still wrong, Guan Yu launched an offensive on Bishui Pass a year ago, and personally took command, and the army came to the city at once, all of which made Li Su unbelievable, Guan Yu launched an attack on Bishui Pass with lightning speed, not only Li Su was stunned, but even the general Zhang He was shocked

Li Su saw Guan Yu's army surrounding Bishui Pass layer by layer on Bishui Pass, and his heart was suddenly bottomless, Guan Yu's army This neat and uniform team greatly surprised him, although he knew that the Xiliang soldiers were brave and the Guan Yu army was extremely strong, but he couldn't believe his eyes when he saw today's Guan Yu army, these iron horses were never seen before, much stronger than the equipment of the previous army, and the weapons in his hands were also much more advanced, so many war horses and such strong equipment, it seems that this is Guan Yu's later development, It's a new powerhouse, not to mention that it's hard to resist the enemy just by looking at this formation! Li Su didn't expect that Guan Yu's army had been improved again in a short period of time, and then he saw that Guan Yu was still energetic and majestic, and the two generals around him were also heroes, very brave, Zhang He said that Li Su said: "It is said that Guan Yunchang is invincible in the world, and it is really extraordinary to see it today!" ”

Li Su persuaded Zhang He: "Guan Yu is powerful, and it is really difficult to compete with him." We might as well stick to it, and send a detailed message to the Lord in an urgent situation, so that the Lord can send troops to save him! Otherwise, the water pass will be in danger! ”

Zhang He nodded after hearing this: "Immediately send someone to ask the lord for help, I will deal with it here, I want to see if he Guan Yu has three heads and six arms!" ”

Li Su hurriedly persuaded: "The general is brave, but Guan Yu is a brave person, and it is better to stick to it if you can't take advantage of him at all." Wait for the Lord to send troops to rescue! Once there is a loss, it is difficult to protect the water! ”

After hearing this, Zhang He pondered slightly: "What you said is not unreasonable! Guan Yu is cavalry to come, if it competes with it, it will definitely be at a disadvantage, it is better to have a deep ditch barrier to block its edge, Guan Yu's army is good for a quick battle, if it is a decisive battle with it, it is tantamount to hitting a stone with an egg, and killing themselves, we must wear down their will, and fight a protracted battle with them, so that their cavalry is difficult to play a role, so the cold winter is prolonged. It's freezing and I'm going to see how they live! It won't be long before it will recede! Even if we don't retreat, we will have a better chance of attacking the city! ”

After Zhang He finished speaking, Li Su was surprised to hear it, and praised it again and again! Now Zhang He is his hope! This young man who is much younger than himself is very strategic, and he is even more outstanding in military affairs, don't look at him as only 24 years old, but he is not even as good as him, who is 10 years older, Zhang He is his backer, and it is Li Su's only hope, Li Su tries his best to assist him in doing things. is waiting for this day one day, Zhang He can be the only one for him. Because Guan Yu is too powerful, the two of them are discussing in the city, and someone in the city has already shouted: "The guards of Bishui Pass listen, Prime Minister Guan Cheng's troops are coming to the city, and if you know it, you can quickly show the city to disarm and surrender to avoid death, otherwise Prime Minister Guan Cheng will command the army to raze Bishui Pass to the ground." Walk on your powder, which is more important and understand! ”

After hearing this, Zhang He replied: "It is said that Guan Yunchang is invincible in the world, I, Zhang He, want to see and know, if there is a kind, let the horse come!" It's not so easy to hand it over! ”

Guan Yu was furious when he heard this: "Could it be Zhang He and Zhang Junyi?" Young Qingqing actually said wildly, it seems that you don't know how powerful your grandfather Guan is! There's a kind of downtown to fight me! ”

After hearing this, Zhang He sneered in the city: "The eldest husband does not fight for the length of the moment. Don't be brave enough to be a horseman, Guan Yu, you are powerful, even if you attack the city! I'm not going down to fight you! ”

Guan Yu was about to answer, but saw three arrows flying from the city and shooting straight towards Guan Yu, Guan Yu's eyes were quick to see the Qinglong Yanyue knife lifted, but he heard "Bang Bang Bang" three times The three arrows were stopped by Guan Yu's horizontal knife, Guan Yu looked for the arrow and looked at the archer It was Li Suye! Guan Yu was furious when he saw it: "Vertical Zi'an dares to do this!" ”

Li Su was shocked when he saw that the three arrows were actually stopped by Guan Yu, Li Su was shocked at the moment when he failed to assassinate Guan Yu, and Li Su was shocked into a cold sweat when he saw Guan Yu's persecution: "Yun Chang, you and I have been thicker for many years, why do you force me?" I didn't help you a lot today! Why drive people into a corner? ”

"Li Su, you are no longer my brother, you are a fool of profit, and you are even more shameless and the grass on the wall falls with the wind, and you have come to beg me now that you have lost power? Why bother in the first place when you know today? What did you think when you betrayed me and defected to Yuan Shao? Don't you feel shameless that a person like you still has the face to live in the world? ”

Li Su was counted down by Guan Yu in the city! Losing face in front of the army, Li Su's seven orifices were smoking, and he scolded tremblingly: "Guan Yu, you kid is a wolf, I can see that you want to kill the old man in the past!" lest I leave you with a trick in the world, but I will speak of you in front of the armies today! Dong Zhuo is not thin on you, but you killed him, I have been thick with you for many years, but you want to fight each other with a knife, such a ruthless and unrighteous person actually wants to bite back, I try to ask who is shameless? Who climbed on someone else's shoulders and stepped on someone else's top? This time, in turn, you have to unload the mill and kill the donkey? ”

After Li Su finished speaking, Guan Yu retorted: ""|Li Suxiu wants to stir up nonsense, your set is just a fallacy and heresy, Dong Zhuo bullied the king, killed the monarch and destroyed the lord, ruined the people, brutal and unkind, full of evil, everyone will be punished, killing him is the will of heaven and calming the hearts of the people is the desire of the people, what kind of morality is it against killing him? This gang of chaotic ministers and thieves will never be at peace except for the country! I'm just conforming to the will of the people for the way of heaven In addition to this thief, and here I want to criticize you, didn't you say that you also participated in the beginning? What kind of person are you? Praise people in the sky and trample on the ground, now everyone finally sees his true face! He Li Su is such a person! ”

"You 、、、、 you 、、、" Li Su's beard straightened when he heard Guan Yu's words in the city, and he kept pointing at Guan Yu with his finger, and commanded the archers in the city to release the arrows. The hoplites were all armed forces, all of them were armored and even their horses were armoured, and they quickly gathered together, forming a copper wall and iron wall, and the bows and arrows on the city were immediately stopped, and they fell to the ground with a crackling sound

Guan Yu's heavily armed troops blocked the attack from the city. At the same time, Guan Yu's siege special forces are ready under the cover of heavy cavalry, and now this siege special forces not only have experience in attacking the city and grabbing the land, but also have undergone special training, and the quality of the personnel is extremely high, not only that, this force has also achieved preliminary science and technology, the last time Cao Cao attacked the Tiger Prison Pass launched a new siege weapon, what weapon? That is the train, this kind of train is also a way to attack the city first used by Cao Cao's army when attacking the Tiger Prison Pass before, and this kind of train is a special tool for burning the city gates. The cart was equipped with a stove, filled with grease, boiled with a charcoal fire, piled up dry wood around the cart, pushed the cart under the city gate, set fire and left. For example, if the enemy in the city pours water to extinguish the fire, the flame is higher because the oil is lighter than the water. It is easier to burn down the city gates. Of course, this train was mainly designed for the suspension bridge outside the city gate, and this method was first put into use during Cao Cao's attack on Tiger Prison Pass. After the sergeants of the Tiger Prison guarding the city obtained, the sergeants guarding the city witnessed the attack of this train, Zhang Fei obtained the basic principle of the construction of this car through investigation, and then reported the news to Guan Yu, Guan Yu then began to build this kind of car after the principle was scrutinized, which was also the first time he put this kind of car into use.

Guan Yu's train shape is relatively large. However, the speed and efficiency of the attack should not be underestimated, in order to prevent the people pushing the cart from being attacked, a large iron partition was set up at the back of the cart to block the enemy's attack and the attack from the burning flames of the cart, so as to build a safety line for the people pushing the cart. Zhang He, who was above the Bishui Pass, saw that the defense under the city was so strong that it would only be a waste of bows and arrows to continue shooting, so he ordered the archers to stop shooting and prepare to observe Guan Yu's next move, Li Su ordered the sergeants to continue to mobilize materials and defensive equipment to the city to deal with Guan Yu's next offensive, but saw that Guan Yu's army heavy cavalry was divided on both sides, and the entire copper wall suddenly cracked a hole, which became bigger and bigger, and a whole road was opened, accompanied by the dispersion of the army. But I saw a train roaring from behind, and the whole car was sprayed with tongues of fire, emitting thick black smoke, and the speed of the train was very fast, and it was like a big fireball rolling towards the suspension bridge of the city gate of Bishui Pass.

Zhang He saw clearly in the city that this was clearly coming to my suspension bridge, and it was not so easy to burn down the suspension bridge in one fell swoop, but this train was really good, the shape was so big, the fire was so fierce, Li Su couldn't help but sneer when he saw the train of Guan Yu's army coming: "Guan Yu knows that this cold day will send us a fire to keep warm, I really miss us!" Ha ha! After saying that, he instructed the sergeants to quickly prepare cold water and prepare to extinguish the fireball in one fell swoop when the fireball was approaching, Zhang He couldn't stop staring at the "fireball", he saw that the fire was so fierce and billowing black smoke, the fire was so fierce in such a cold sky, it must have been filled with oil, Zhang He observed carefully, and waited until the train approached Zhang He finally confirmed his guess, Li Su saw that the train was approaching and hurriedly ordered the sergeants to pour water on the train, ready to extinguish the train, Zhang He saw this and hurriedly stopped: "Don't be in a hurry to do it first!" The fire is so big, there must be oil in it! ”

Li Su said disdainfully: "What if he has oil, what can he do if he has oil, the dripping water freezes on such a cold day, and the water that falls down immediately becomes ice, what can he do if he has oil?" ”

Just said that he hurriedly ordered the soldiers in the city to pour water, the train rushed to the drawbridge with thick smoke, and several buckets of water fell down on the city at once, and went straight to the train to pour it, but saw that the train was hit by the water, and the fire rushed out of the "boom", and it was more violent, Zhang He saw this and hurriedly stopped it, the train must not be attacked with water, and quickly prepared sandbags to suppress the fire of the train, and the soldiers in the city were about to throw sandbags to drive up, but at this moment, they saw dozens of large stones thrown in the air at once, which were twice as big as people's heads, A large stone that fell from the sky suddenly fell on the soldiers in the city, and these soldiers were either killed or wounded, and soon fell down one piece, and the city was suddenly in chaos, and the stone bounced from the air. It is already very heavy and external force, so it is extremely difficult to resist, and there are dozens of them at once, the attack is extremely fierce, the defenders of the city only have the ability to parry and have no power to fight back, such an offensive can not even resist the shield, as long as the hope of survival is very slim. Survival is a human instinct, and in the face of such a fierce offensive, it is normal for soldiers to escape

It turned out that Guan Yu's army sent a train to attack the city gate suspension bridge at the same time, the "thunderbolt" in the distance was gradually ready to drive, when the train approached the city gate, the thunderbolt car launched a fierce attack together, at this time the thunderbolt car has been transformed by Guan Yu The lethality is amazing, the so-called "thunderbolt" throwing car is to set up a shaft horizontally on a wooden frame, and the middle of the shaft wears a long wooden pole with toughness as a throwing rod. One end of the rod is tied with a leather bag connected by ropes, and the other end is tied with dozens to hundreds of ropes, and they are pulled hard together at the command to use the principle of levers and centrifugal force to throw the boulder out. Of course, it is not necessarily the stones that are thrown, this is the most basic principle, Guan Yu's improved thunderbolt is made of iron throughout, of course, the frame is cast iron, and Guan Yu's improved thunderbolt is equipped with wheels at the lower end. Maneuvering is possible, and the improved Thunderbolt no longer has to be pulled by a rope at one end. Instead, a huge stone is tied to the end of the gun, an iron hook is installed on the gun carriage, and the gun shaft is hooked. The tip of the cannon was pressed down, and at the same time, a stone bullet weighing 100 pounds was thrown suddenly. This kind of sports car saves manpower, is easy to use, has great power, and the force of the lever has also been multiplied. The combat effectiveness of such a tool will be greatly improved, and the attack power is amazing, because this kind of force is huge, and the number of stones that can be thrown at one time is not only large but also very large, Guan Yu launched five chariots this time, and the attack power of these five chariots is equivalent to dozens of vehicles in the past.

Five chariots took turns to shell the stones at Bishui Pass, round after round, the sky of Bishui Pass was like a hail of stones, but the size of these "hailstones" was too big to parry, even the main generals Zhang He and Li Su had to retreat when they saw such an offensive, it was so strong, if you don't dodge, it would be a dead end, smart people don't need to be strong in front of this situation, no one can make it! Guan Yu also came prepared this time, prepared enough stones, the stones in the cold winter season are particularly hard, and the walls of Bishui Pass are full of loopholes, in fact, Guan Yu doesn't want to attack Bishui Pass in this way, after all, this will be his own in the future, he doesn't want to bother to repair and invest again, he originally wanted to win at the lowest cost, but now it seems impossible.

Storming Bishui Pass is definitely not Guan Yu's best strategy for this expedition, originally he thought that Zhang He would go out of the city to fight with him, as long as Zhang He went out of the city, he would be defeated, without Guan Yu going out, Ma Chao and Pang De would be able to clean him up, and Guan Yu was also ready to use the Eight Gates Golden Lock Array to lock Zhang He's return route and trap him alive, forcing him to be captured, but he didn't expect Zhang He's kid to be cunning enough, seeing that Guan Yu was so powerful that he was sticking to the city and preparing to deal with Guan Yu, but "the magic is one foot high and one foot high", Guan Yu has always been a last resort, He can almost think of what others think, and he can think of what others can't think of, with advanced thinking, it can also be said that he can be counted in front of others, such a strategy allows him to defeat his opponent again and again, Zhang He is cunning but is naturally not an opponent compared to the resourceful Guan Yu, Guan Yu not only made sufficient preparations in material but also made two preparations in strategy, Guan Yu also speculated how to attack Bishui Pass if Zhang He did not go out of the city to face the battle

In fact, Guan Yu has one of the most perfect strategies to attack Bishui Pass, what kind of strategy? That is, to surround the Bishui Pass and cut off the connection between the Bishui Pass and the outside world, cut off the supply of the Bishui Pass, and then create a kind of closed door and fight the dog, so that the Bishui Pass has become a lonely city, and then besiege but not attack, and wait for the time when the supply in the pass is not enough to attack, so that it will be a sure victory, and it can minimize casualties, and the Bishui Pass will also be protected from destruction, this is the best way to attack, but it is almost impossible to implement such a plan within 20 days, and it will take several months to do this. But time is obviously too late, this plan can only be zeroed, in order to capture the Bishui Pass in a short period of time, it is necessary to fight a tough battle, to deal a heavy blow to the Bishui Pass, forcing the Guanshang to surrender and surrender to the enemy, withdraw from the pass or destroy on the spot! Of course, the cost of doing so can be imagined, not only will there be casualties, but damage to the city is inevitable! (To be continued......)
