Because Cao Ren divided his troops to Zhang Liao, Zhang Liao restrained Guan Yu, so now there are some obstacles in communication between Guan Yu's camp and Zhang Xi's Fancheng.

Although there will be no disconnection, the transmission of information to each other will be affected to some extent.

But with such important information, Guan Yu believes that Ma Liang, a person sitting in Xiangyang, should not be mistaken, right?!

Since Ma Liang can send Wang Ji's military newspaper to himself, it shouldn't be difficult to send a copy to Fancheng. Why did that kid actually persuade himself to come back to help after learning that Gangneung was fine?!

Guan Yu didn't understand much, but Guan Yu believed in Zhang Xi's judgment.

Although Guan Yu is arrogant, Guan Yu's arrogance is just unhappy with those who have no real ability but are a vegetarian meal, Guan Yu still respects and trusts those who really have ability.

Zhang Xi, this kid, although Guan Yu really didn't look down on some of his behaviors at first, but after getting along with each other over the years, Guan Yu still recognizes Zhang Xi's ability.

Although this kid is a little timid, his judgment is rarely wrong.

Since he felt that Jiangling was still in danger, Guan Yu couldn't leave it alone.

After thinking for a while, Guan Yu decided to let Ma Liang transfer another 10,000 defenders from Xiangyang, regardless of whether the reorganization was over, and let Liao Hua lead him to rescue Jiangling.

As for the front line, this cannot be withdrawn.

Although Zhang Xi said that he relied on Fancheng's troops and was sure to block Cao Ren's 60,000 attacks for two months, Guan Yu did not dare to let Zhang Xi take risks.

Since ancient times, defending a city has been to cooperate with the inside and outside. If you stick to the city, even if you are a good general, there will be times when you lose it.

Guan Yu couldn't let Zhang Xi take this risk alone.

One more. Guan Yu is old.

Really, although Guan Yu doesn't want to admit it, he is already in his fifties this year and will be sixty soon.

In this era, a person of Guan Yu's age is already considered to be a long life.

But in the current world, there is still no meaning of peace, and the overall situation is still Cao Cao's strength, and the Sun and Liu families are weak.

The ideal of the eldest brother Kuang Fu Han Dynasty seems to be impossible to achieve quickly in a short period of time.

Therefore, Guan Yu can't let Zhang Xi take risks, after all, the Mesozoic generals represented by Zhang Xi are the hope for the future.

Therefore, Guan Yu not only couldn't let Zhang Xi defend Fancheng alone, but he also decided to launch a surprise attack on the camp where his old friend Zhang Liao was located.

The purpose is to attract as many Cao Jun as possible to his side and help Zhang Xi in Fancheng reduce the pressure.

The next day, Guan Yu personally led a large army and launched an attack on Zhang Liao's camp.

Ke ZHANG Liao. After all, Zhang Liao is the famous general of the White Wolf Mountain Formation, Xiaoyaojin 800 and 100,000, even if he leaves Sun 100,000's buff blessing, his combat command ability will not be weakened in any way.

Guan Yu attacked, Zhang Liao defended, and the fight between the two sides went back and forth, and Guan Yu couldn't take advantage of it for a while.

The command ability of the two sides is almost the same, although Guan Yu's side relies on the sharpness of the ordnance and occupies a slight advantage, but Guan Yu is all infantry, and Zhang Liao, he has 5,000 cavalry.

As soon as the critical moment came, Zhang Liao dispatched cavalry to raid, and the little advantage that Guan Yu had finally accumulated would be pulled back by Zhang Liao in an instant.

Guan Yu has tried his best, but in his army, because he has to cooperate with the naval army in the early stage, there are more crossbowmen, and there are too few soldiers with long weapons, only the five thousand mandarin duck soldiers, and not all the mandarin duck soldiers have long spears, and the proportion of long spears is only two-fifths.

In other words, even if Guan Yu unified all these spearmen and soldiers, it would only be two thousand pikemen.

With two thousand pikemen to five thousand cavalry. I can't beat it.

Not to mention defeat, to block the assault of 5,000 cavalry, without 10,000 pikemen, really don't even think about it.

Now Guan Yu really doesn't have so many pikemen.

As for the Pak Daobing. It's not that Guan Yu didn't think about it, it's really the three thousand Pu Dao soldiers, firstly, the number is not enough, and secondly, the Pu Dao plus the long pole is only two meters long, and it is impossible to cooperate with the pikemen above four meters at all, even if it is barely mixed, it is impossible to stop the cavalry, it is better to put it for the time being, and then release it to kill the enemy at a critical moment.

Therefore, Guan Yu could only use ordinary methods to launch an attack on Zhang Liao's military array.

But all this, Zhang Xi, who is upstairs in Fancheng City, is more incomprehensible to see.

It's not the second master, are you making a mistake?!

We're supposed to be on the defensive, right?!

According to common sense, shouldn't the second master use the mandarin duck soldiers and the car formation to form a defensive formation to lure Cao's people to attack, why did the second master attack himself? !

Did the second master make a mistake?!

The person who should really be anxious now shouldn't be us, it should be Cao Ren.

Why hasn't Cao Ren started attacking the city yet, and the second master's side has begun to take the initiative to attack?!

Zhang Xi didn't understand, but Zhang Xi was very fast, and he didn't have much time to watch the second master attack Zhang Liao. Cao Ren finally made siege equipment and began to attack.

Cao Ren's siege this time took almost a month to prepare.

Cao Ren is also a generation of famous generals in the end, and he has the qualities that a famous general should have.

Although he had been irrational after being ridiculed by Zhang Xi before, after calming down, Cao Ren still showed the greatest calmness and patience, formulated a strategy for this siege, and even spent extra time preparing for this.

Therefore, when Cao Ren was triumphant and pushed his killer weapon under Fancheng, Zhang Xi on Fancheng was a little dumbfounded when he looked at it.

"This is, catapult?!" Zhang Xi's face was a little solemn, looking at the more than twenty catapults in front of the Cao army's array, and muttered to himself.

Zhang Wei, who was standing beside Zhang Xi, also had a bad face, and hurriedly asked Zhang Xi for his life, saying, "County guard, please allow the villain to lead three thousand troops out of the city and burn these catapults." ”

Zhang Wei had never seen the power of Cao Jun's catapult, but he knew the power of his catapult very well.

If we compare the power of our own catapult, no matter how strong the wall of Fancheng is, it will not be able to withstand the continuous bombardment of the catapult, and sooner or later the city wall will be collapsed.

Therefore, it is inevitable to go out of the city and burn the catapult.

But Zhang Xi waved his hand and thought for a while before saying, "Let's take a look first." ”

Zhang Xi knew that Cao Jun had used a catapult, the kind of thunderbolt that Liu Ye supervised and manufactured. But the power of that thunderbolt, Zhang Xi is not clear, and if he rushes out of the city, he may fall into Cao Ren's calculations.

And Cao Ren has something to say, of course Cao Ren can't wait to break Zhang Xi's body into ten thousand pieces.

If Cao Ren can't defeat Zhang Xi in Fancheng and be ashamed, then the name of "Slipping Side" will accompany him for a lifetime.

People in these years are all face-saving, and with such a name, Cao Ren must have hated Zhang Xi to death.

However, Cao Ren also knows that Zhang Xi is not easy to deal with.

Although there has never been a chance to fight Zhang Xi directly, it is not the first time that the two of them have fought indirectly.

Whether it was Cao Ren's sneak attack on Xinye when he led his troops, or the battle under Nanjun City, Cao Ren still knew a little bit about Zhang Xi's combat style.

You expect this person to be able to go out of the city to fight in the field with a hot brain, which is basically impossible.

Therefore, in the end, this Fancheng will inevitably fall to the point of a tragic siege battle.

Since you want to attack the city, you must be fully prepared, and you can't easily launch an attack, Cao Ren has not attacked for a month, but he is preparing all kinds of siege equipment, especially this thunderbolt.

I had already learned from Man Pet that Zhang Xi had attacked Fancheng with a catapult, and the Man Pet had no defense, so Cao Ren decided to return the favor to the other in his way.

Catapults, it's not just your Liu Beijun family, learn about the thunderbolt in Hebei back then? !

In order to build these thunderbolts, Cao Ren also sent people to Xudu, invited the craftsmen who made the thunderbolts, and spent a full month to build these batch of 20 thunderbolts.

Now, the offensive and defensive situation has changed, and it is his turn to attack Zhang Xi, who can abandon the city with a catapult, can't he concoct the same method?!

The current Cao Ren is very confident.

Not long after, Cao Renjun's offensive began.

Sure enough, the first one to take the field was the Thunderbolt.

Twenty thunderbolt carts loaded with stones, and under the traction of manpower, they began to pour stones in the direction of the walls of Fancheng.

Zhang Xi breathed a sigh of relief after seeing the thunderbolt wielding.

Cao Jun's thunderbolt is still the kind of traditional catapult pulled by manpower after all.

Although I don't know what structural principle Liu Ye used, which caused the range of the thunderbolt to reach a terrifying 200 steps, but the power is still pulled by manpower, so there are two problems that cannot be avoided - insufficient accuracy and unstable range.

Three of the stones thrown by the first batch of Cao Jun did hit the city wall, but the remaining stones were scattered within twenty to sixty steps in front of the city wall. This range and accuracy are simply too unreliable.

If you want to smash the city wall with such a catapult, you really have to look at the character and fight the probability.

However, you can't just leave it alone, after all, there is always a probability, and it doesn't work if it is smashed for a long time, so you have to find a way to solve these thunderbolts.

Judging from the conventional way of disposal, to destroy the siege equipment, that is, to send people out of the city to kill the guards and burn them.

But. Zhang Xi believed that a general of Cao Ren's level would not give himself this opportunity easily.

Cao Ren would definitely send a large army to protect these thunderbolts, and might even find a way to surround the soldiers sent by Zhang Xi to fight in the city, killing and wounding as much as possible and weakening the garrison of Fancheng.

This is equivalent to going to the field with Cao Ren to decide the victory.

Cao Ren definitely hoped that Zhang Xi would do this, after all, Cao Ren had a lot of soldiers, and the difference in the combat power of the soldiers on both sides was really not too big.

But Zhang Xi definitely can't let Cao Ren get his wish. Guan Junhou and Zhang Xi combined are less than 30,000 people, and they are crazy to fight with you for 60,000 people.

Therefore, Zhang Xi put the choice of going out of the city and burning the thunderbolt as an alternative, thinking about whether there was a better way.

There is indeed a way.

Cao Ren has a thunderbolt, and Zhang Xi also has a heavy catapult.

Zhang Xi didn't want to use this method so early, and planned to use it at a critical time to block Cao Ren's siege.

But who knew that Cao Ren would use the thunderbolt as soon as he came up, and there was no way to do it.

Zhang Xi ordered to find a way to push his heavy catapult onto the city wall.

But there's a problem

The height of the wall of Fancheng is 8.15 meters, the distance of the thunderbolt is about 120 meters, and the range of the catapult on the flat ground is only about 90 meters.

Ask, if you move your own catapult to the city wall, can you smash the enemy thunderbolt?!

Zhang Xi felt that he couldn't calculate this arithmetic problem, but it didn't matter, we could use the exhaustive method and try it one by one.
