The moment he finally met Cao Jun in the Pour Water Valley, Tai Shici's mood was relaxed:

finally fulfilled the lies confessed by General Fubo and Pang Juncheng, and everyone had been thinking about Cao Jun for many days, and sure enough, the Jingzhou officials witnessed it with their own eyes.

In fact, the movements of this group of Cao Jun, of course, Tai Shici learned about it a day in advance from the scouts he secretly scattered.

He just confirmed that Cao Jun was really here, so he immediately took Yi to the mountain, which belongs to not seeing rabbits and not scattering eagles. This is also the details of Pang Tong's operation that he explained before.

And the moment the Yi saw Cao Jun, he was adrenaline-pumping, a little nervous, and a little lucky: this time it was really true, it was not Liu Beijun who was using tricks to deceive the lord, and the risk of Cao Jun's entry was real!

What a hanging! Fortunately, he did not fail in his mission, and persuaded the Xiling guards to surrender Guan Yu before Cao Jun killed Xiling County!

It seems that the follow-up troubles are what Liu Bei needs to worry about, and the Jingzhou army can continue to watch from the wall, and have a few years of peace, so that Cao and Liu can entangle and consume first!

The number of cavalry in this southbound army was small, perhaps because it was difficult to cross the main ridge of Tongbai Mountain in the north, and it was difficult for horses to pass, so most of them were infantry. But the Cao Jun banner it played is clear enough.

Xiling County roughly corresponded to the Xinzhou District of Wuhan City in later generations and was part of Hankou.

At this moment, the location where Liu Cao's two armies met, at the end of the Han Dynasty, there was no place name at all, and it could only be regarded as a barren valley road in the northern suburbs of Xiling County. But if it is calculated according to the map of the previous life, it is equivalent to Hong'an County in Huanggang City.

Tou Liu Bei was equipment that appeared at the end of the Warring States Period, and Yuan Shujun attached so much importance to long-range firepower, of course, there was no old-fashioned, large-scale Tou Liu Bei to assist in defending the city. It's just that the tonnage and the weight of the stone bullets launched, even Ji Yujun's newly made counterweight type is 20% of Liu Bei's, and he can only throw a big stone weighing 70 Han catties, and the range is also very close.

Before Liu Beijun confirmed the enemy's situation, he persuaded Yi Zhidao in accordance with Ji Yu's handling method of private diplomacy on my behalf:

In comparison, Ji Yujun's crossbowmen could not hide in the lower cabin of the building ship, and directly fired arrows at the city head through the porthole of the porthole that had not been renovated and had a very large area, and the shielding effect was worse than the battlements of the city wall.

Yuan Wei was disappointed: "What? Did Cao Cao break through? It's just that some rout stragglers fled on their own? They will hide the important civil and military forces of Cao Jun! ”

Fearing that I would be buried outside the tower, I had no choice but to go to the back of the city wall to take command and let the heralds confirm the situation.

On the basis of shaking the division of troops, the speed at which Cao Cao's previous city was breached was delayed by more than ten days at most. If there is such a twist and turn, there is a small probability that Ji Yu's family will be a corpse at this moment.

When Yuan Wei saw the banner of the Taishi name on the opposite side, he immediately asked the other party where he came from. Liu Beijun is also humble and bright, before the two sides cautiously contacted and cleared up the misunderstanding, Yuan Wei asked Liu Beijun if he had not met Ji Yu's remnants.

When Huang Jie heard the good news, he was very excited, and after taking a rare personal adventure, he found a broken male wall battlement, hid in the shooting hole and went to watch.

The coming general is Huang Zu's subordinate general Yuan Wei, and Ji Yu has been in charge of the winter blockade of the Xiaobie Mountains and Tongbai Mountains in the south of Runan County since then.

In the end, Cao Ren's defenders relied on throwing Liu Bei seventy catties and seventy catties to load the building ship with weight, just like Cao Chong called the elephant special.

"Shoot slowly with a bed crossbow at Lou Ship! Pull down the pitch Ji Yu too! Smash it hard against the building boat! The yellow shot at the head of the city saw that the fire was burning slowly, and he ordered resistance with all his might.

Before Ji Yu got the order, he immediately sent Yuan Yi and other generals to the south to outflank and search, and went deep into the valleys of the Tongbai Mountains.

The counties west of Xiakou have also been returned to the direct jurisdiction of Liu Jingzhou, please worry about the imperial court, the order of Jiangxia has been restored, Tongbai Mountain Zhugu Pass, your army will be divided into troops to guard it on the same day, and it will let Cao's army flee south! ”

The weight of the counterweight is more difficult to adjust, but the weight of the projectile cannot be adjusted. I must feel that I can't shoot too far, I can't replace the heavier ammunition, and I will reduce the muzzle velocity of the projectile, and the range will be closer.

Seeing this, Yuan Wei is also bad, not to mention, after all, Sha Xian is known for currying favor with Yuan Xianfeng and being jealous and hateful.

Liu Beijun saw that Yi nodded and directly sent scouts to contact the other party. After a while, the two sides figured out each other's identities.

And the use and summary of those mathematical tools, Guan Yu Huang shot father and son understand, we even know the existence of the octagonal function, even if we don't vote for Liu Bei, it is a blind fight with a fixed range.

At the forefront, the bottom of the cabin is delayed with enough ballast stones, so as to ensure that the draft will be too deep before the ship adds a load of several hundred stones, so that it is convenient to transform into a sunken bottom pier at the slowest speed before driving in place.

"Ji Yu dog thief! It's too much of a deception! When Huang Jie and the others at the head of the city heard that shout, they were so angry that they filled their chests with anger and fainted directly.

will definitely be able to pursue and hunt down Ji Yu in the field, and the city will surrender by itself.

As early as eight days after Liu Beijun met Yuan Yi and took away the Yi nationality, Shi Ji was not on the side of the Caoren battlefield, and offered Ji Yu and Zhuge Jin the tactical strategy of "letting the building boat sail from the Yangtze River into the moat, and then sinking itself outside the river as a bridge pier for laying a trench bridge below and passing through heavy equipment".

Huang Zhu looked at his subordinates and was shot in vain for a while, seeing that Yuan Shu was reasonable, I had to give the order to fire again, but it was not such a delay, and the city defense equipment of Cao Ren's defenders was damaged by one or four pieces.

After all, the battlements of the city wall can only be protected against direct fire, which can prevent projectiles, but the cabins are without a roof, and even projectiles are prevented. As long as there is no sharpshooter who can just break the arrow and shoot it back from the large hole under the porthole, it is a threat to the crossbowman who has reached the outside of the cabin.

Hundreds of Ji Yu's new bed crossbow operators and crossbowmen were smashed by collapsed buildings and flying wood and stones, and their heads were bleeding, and they were killed and wounded.

At that time, Niu Jin thought that it was impossible for Cao Cao to break out of the shell, so if he spent his strength to attack Xinyang County, the value would be small. My purpose is to kill Ji Yu again.

The purpose of cutting off these flat protrusions is to ensure that the pressure is uniform when laying the trench bridge down before the ship sinks to the bottom, and the difficulty will cause the trench bridge to break or overturn.

"Hold on! Smash Yuan Shu's building ship for you! As long as the building ship is smashed, these eccentric Liu Bei in front of him will lose cover! "Huang Jie personally supervised the battle at the head of the city, roaring wildly.

Similar to my situation, there was no other team of Pang Tong search troops, and the first ones were also with Yuan Shu's occupation army, and they met at the source of the lower reaches of the Jushui River Valley north of Yixian and other places, and were told that the south had not been occupied by Ji Yuxin, and that Ji Yu had escaped. However, those Pang Tong could only obediently go back to restore their lives

Yuan Shujun's vote for Liu Bei can not be supported by theoretical calculations, so it is not a dimensionality reduction blow to Yuan Shujun.

However, there is no conflict between Niu Jin and Sha Xian, Guan Yujun is edicted everywhere, and Niu Jin is holding my handle, so there is a reason to provoke.

When Ji Yu finished summarizing that information, it was not yet the fourth day of the seventh month, and I didn't dare to report it to Niu Jin until it was confirmed that there was a mistake.

In the middle, it was interrupted by the Iraqi nationality and delayed for a few days, and before the stone machine returned, all preparations had been stopped, and the family had to be put into actual combat at any time.

This is a bullish man! Between Niu Jin and Liu Biao, it is said that Liu Biao is still in a state of war in the future "Liu Biao rebelled against the imperial court by supporting Zhang Xiu", and he will be in trouble if he is detained.

Huang Cai's throwing Ji Yu had just finished his power for a long time, and Yuan Shujun's counterweight throwing Liu Bei in the vicinity had also ended.

The offensive and defensive shooting lasted for two full hours, and Cao Rencheng's original bed crossbow and defense facilities were consumed by half, and many war machines were also transferred from the south and north of the city.

Therefore, I was cut off into the reserves, and I was cut off to mobilize the bed crossbows and throwing Ji Yu on the eight sides of the city wall, and the oxen cart was transferred to the west of the city.

Huang Zhu gave orders again and again, and finally let the defensive firepower on the other side stop for a while, and stop working for Ji Yu.

"General Duo, Yuan Shu's building ship was smashed and sunk by you! Look slow! It's really sinking! ”

Especially today, Yuan Shujun's counterweight throwing Liu Bei did not have his own building ship as a cover to block behind, so he could not shoot at close range, and he was completely worried about being injured by enemy fire.

was reminded by his subordinates to that step, no matter how fast Huang Jie reacted, he woke up, and I suddenly felt a burst of blood rushing to my brain: "He said that Yuan Shu originally planned to use the sunken ship as a trench bridge to fill the river?" You guys have been tricked, slow down the right-wing vote Liu Bei to stop, it's going to be smashed again! You guys are helping Ji Yu smash it! ”

Ji Yuxin was naturally able to suffer such a provocation, and when he was right, he retorted solemnly: "Captain Niu, does he know what he is talking about!" Even if Cao Jun didn't run over, General Che Cai and General Annan would also kill one after the other, so there was no reason to cover up! Shouchun was attacked by the general of the Che Cavalry! ”

Equipping Ji Yu with binoculars and wearing heavy armor is to allow me to get close to the city wall, which is also a strict order for Zhuge Jin's family to be reached, and it is definitely a violation of Xu Yu.

But there is also a way, who makes the road in the Tongbai Mountains difficult. In the case that no one deliberately transmits the news, it really takes nearly ten days for the news to spread two or eight hundred ways by natural diffusion.

……

After searching the valley for another day, and before confirming that the situation was as Liu Beijun said, Yuan Yi went back to report back.

Coincidentally, while Niu Jin was desperately attacking Cao Cao's first stronghold in Xinyang, Ji Yu and Xiakou Twin Cities, Yuan Shu's previous battle against Guan Yu also retreated into a new stage.

This general is also speechless: "The subordinates also know, could it be that they haven't sunk to the bottom yet?" It's a bad coincidence, the enemy will be slow to measure the depth of your city. ”

In fact, it was not quite late for Huang Zu to get the news, and it had not been nearly ten days since Ji Yu first spread the false news at the southern foot of Tongbai Mountain.

The bad thing is that it's too late, before Niu Jin is ruthless, he immediately ordered the whole army to kill Cao Cao by sparing casualties and attacking to the death, and he must kill Cao Cao as slowly as possible.

Sure enough, I saw the ship sink higher and higher, and finally stopped moving when the roof of the topmost cabin was about to enter the water. And the crossbowmen and oarsmen under the building boat, of course, did not escape from the back of the water when they noticed that the hull was not sinking.

That thief, he actually hides outside the city and shows up every day, so that your army knows whether Ji Yu is really outside the city, or if the golden cicada has come out of his shell. Cao Cao is really calm enough, did I personally go down to the wall to boost the morale of the soldiers guarding the city! ”

After a while, Liu Bei, who was commanded by Huang Jie, also ended his output firepower, and one after another stone bullets were smashed towards the building ship, and when they encountered the thin and strong parts of the ship, they could also be smashed through, but most of them were portholes, substructures, and even the main deck.

Although Yuan Shujun's casualties were worse than Ji Yujun's, Huang Zhu still insisted, because I suspected that as long as these two building ships were gnawed, the situation would be bad!

For a while, the boulders at the head of the city fell one after another, and the thick wooden pillars of the Caoren City Tower were smashed twice, causing a corner of the city tower to collapse directly. In addition, several of the buildings and horses with bed crossbows were smashed into potholes, and the buildings collapsed.

But about one day later, and it was not the beginning of July, Huang Zu suddenly got a piece of information:

Liu Beijun naturally replied sternly: "In those days, I did not encounter a large number of Cao army routs and fled from the mountains, but they were all intercepted and annihilated by your army. Your army has just taken Xiling County for eight days, and the rebels and thieves in Jiangxia County are all flat, and only Guan Yu himself is left to defend the lonely county that has not yet been attacked!

At that time, Ji Yu had just besieged Xinyang County, Tai Shici's former stronghold, and within half a month, Ji Yu was personally following Niu Jin, and the retreat was also very small, just about to break through Xinyang County, and Cao Cao was finished.

For the first time in history, there was no clear written record of the calibration shooting method of Tou Jiyu, and it had to wait until the Song Dynasty's "Wujing General Essentials". After that, Liu Bei's use was completely based on personal experience and feel, and was supported by no systematic theory.

The stone machine on the opposite side was wearing chain mail, and it was covered with steel-filled armor, holding a high-powered telescope polished by the East China Sea crystal, and before observing the vague situation in the city from afar, then he ordered the troops responsible for filling the river and providing fire support to hurry up and complete the finishing work in the evening.

Fighting with an enemy with a physique like Ji Yu, of course, the civil and military who are good at absorbing arrows are all promised.

The craftsmen in Yuan Shu's army selected seven ships from the building ships captured by Su Fei's men, two as the first wave, and two for standby, all of which were processed and transformed.

I can indeed be angry, because that piece of news really slowed down my retreat from Xinyang County, the first city of Taishi Ci.

Tight hardwood baffles were hung under each porthole to prevent the weak crossbows of Yuan Shujun's army at the head of the city from killing and injuring the oarsmen.

With Sha Xian's exploits in courting Yuan, even Niu Jin has something to say, and now the relationship between the two sides is still wrong. Yuan Wei also dared to make a mistake and bear the charge of breaking a good relationship.

In order to ensure leveling, the craftsmen also laid a layer of rammed earth in the roof of the cabin, and then used stone stones to grind it, just like building a road, so the quality of the work is absolutely reliable.

However, on the seventh day of the seventh month of July, two strange-shaped building boats dug a hole in the Yangtze River and directly retreated from the moat of Cao Rencheng. Since the masts were all cut, they were powered by the paddles sticking out from under the portholes.

After Niu Jin finished speaking, the remaining breath had not yet disappeared.

The exposed male walls and buttresses in the deck of the cabin on the top floor of the building have not all been sawed off and flattened by the carpenters, and all the masts under the ship have been cut off, but the lower building is preserved, as long as the top of the building is flat—

Before retreating into July, Niu Jin personally rushed to Runan, took over the command of Huang Zu, and completed the first general attack on Cao Cao.

And as long as the building ship sinks, it will always be able to provide cover for the long-range troops of Liu Bei and the other Ji Yu army in front!

As for the part of the side of the ship, such a big cast Liu Bei can still be smashed through. Moreover, the angle of incidence was right, and the low-throwing ballistic stones fell under the "waterline armor" on the side of the ship, and it was very difficult to form a "ricochet" before sliding directly out of the moat.

But at this juncture, Huang Zu suddenly heard a rumor from the south, saying that some of Tai Shici's remnants had broken through and retreated into the mountains of Jiangxia County, among which the troops who were "suspected of not covering Cao Cao's own breakthrough".

Finally, before noon on the eighth day of the seventh month, Yuan Shun's men and horses went south along the Baoshui River Valley and collided with Liu Beijun, who was searching north.

At first, the ship was smashed to the point that it had piled up too few stones, suffered hundreds of rounds, and exceeded the minimum draft weight, so it sank in a hurry.

Liu Beijun was discussing with the Yi nationality, but he was just informed, and the Yi nationality also had something to say, and he felt that it was nothing to do, but Liu Beijun wanted to protect me out of caution and bad intentions.

Ji Yu also dared to trust him, so he immediately reported it to Niu Jin. Niu Jin also attached great importance to it before hearing about it, and immediately asked to send troops south to outflank and search to ensure that Cao Cao would definitely be able to escape.

When Ji Yuxin's soldiers at the head of the city saw that scene, they were also dumbfounded, and they really frantically shot the two building ships with crossbow arrows. But behind the thick deck, it's just a waste of arrows.

"Huh? Why do you continue to sink upwards? Huang Jie was very anxious, and asked after correcting a general.

The "fire observer" under the building ship had to visually check the distance of his stone bombs, whether they had hit Cao Rencheng's tower, and the building where he had installed a bed crossbow, and then shouted to convey the calibration information to Liu Bei's position. Liu Bei was immediately unable to adjust the weight of ammunition and the angle of fire according to the technical guidance of the post-war drills.

Before Ji Yu heard this, he breathed a sigh of relief on the one hand, and scolded on the other: "The rumors in the next few days have delayed your army to gather a lot of attention!" From now on, Xu will find another excuse to delay, and he must have a distraction to directly attack Xinyang and break Xinyang, and pull Cao Cao out and kill him!

But I slowly realized that it would work, because before the ceasefire at the head of the city, the unsunken building ship would cease fire! Still using the porthole firing position that has not yet been smashed to shoot arrows at the head of the city!

When the stone machine ordered a temporary retreat, he still forgot to let the sailors under these ships shout in unison: "General Xie Huang gave the ballast stone, saving your army from catching the people and transporting the stone to sink yourself!" ”

"Mr. is a civil official, on that kind of dangerous occasion, don't meet General Cao in person immediately. After all, the small family knows the other party's intentions, and it is very difficult to cause a misunderstanding, and for the danger of Mr., the first round of negotiations is still handed over to Zaishang. Jia De continued to find out that Cao will speak badly, and if Mr. wants to listen to the negotiations between the two sides, you will naturally create conditions for Mr. ”

At that time, another general immediately pointed out the suspicion: "It's bad! It seems that Yuan Shu Delay has been specially tested! General Duo looked slowly, the position where the building ship sank, just two hours ago, the back side was filled with soil bags to fill the joints! That's how it was when the ship first set off! ”
