"Bang!" In Jiangxia City, in Cao Cao's tent, Prime Minister Cao Cheng opened his tiger eyes, his tiger beard trembled slightly, and he scolded: "Grandma, Lao Tzu didn't beat him, he Sun Zhongmou started Lao Tzu!" It's fat! ”

"Prime Minister, Sun Zhongmou doesn't know how thick the sky is, and he must learn a good lesson!" Yu Ban shouted first. Last time, this guy was ordered to attack and intercept Zhuge Dad's envoy boat, but he was almost sunk into the river by Zhou Yu to feed the fish, which cost face. Although Cao Cao did not blame, he has always been ashamed. During this time, my mood was quite low, and I always wanted to find a chance to be ashamed.

"Prime Minister! Our army has been besieging the city for several months, and the soldiers are already exhausted, and at this time, it may not be good for me to go south for a decisive battle with the Jiangdong Army! I think it's better to send troops to relieve the siege of Hefei first! As for Sun Quan, he is just a grasshopper after the autumn, and he can't jump for a few days! After Xun Shangshu transports the grain and grass in the rear, it will not be too late for us to take revenge! Cheng Yu is an old man who seeks the country, and he knows that Cao Jun is very tired at this time. From the southern expedition in August of the thirteenth year of Jian'an to the conquest of Jiangxia County at the end of October, Cao's army has been fighting continuously for more than three months. The food and grass are scarce, the soldiers are tired, if you go south at this time and fight a decisive battle with the Jiangdong Army, which is in full swing, the outcome is unpredictable!

"Yes!" Cao Cao nodded. No one knows Cao Jun's situation at this time better than him, the commander. The soldiers were tired, the food and grass were insufficient, and the resistance within Jingzhou was ready to move. A few days ago, Le Jin, the guard general stationed in Xiangyang, also sent someone to report, saying that the bandits in the Xiangfan area have a tendency to become bigger, and I am afraid that it is related to the secret support of the Jingzhou clan. Once Cao Cao's army marched south, the bandits in Jingxiang took the opportunity to cause trouble, and the consequences were unimaginable! "Then according to Zhongde's opinion, who should be sent to rescue Hefei?"

"If it is not General Zhang Liao, it is not enough to take on this position!"

Hearing that Cheng Yu recommended Zhang Liao, Yu Ban's nose was almost crooked, and he was suddenly full of cows! What an opportunity to make meritorious contributions!

Outside the city of Hefei, Jiangdong Terracotta Battalion.

Zhuge father and son have been quite leisurely recently, and these two goods are used to arranging jobs for others, and then doing nothing themselves. As the saying goes, "civil officials move their mouths, and military generals break their legs." "That is to say, these two goods are like this. When Cheng Pu and Sun Yu came to the Lusu camp angrily to ask when they would attack Hefei. The three guys flickered and carried out the task of the two generals.

In the past few days, Cheng Pu's interest has been particularly high. Young Master Zhuge gave the blueprints of the thunderbolt cannon invented by Cao Cao that he saw in later generations to the craftsmen in the army, and the craftsmen in Jiangdong were really effective. Working day and night, it only took three days to make more than a dozen thunderbolts. In fact, although the so-called "thunderbolt" has a great reputation, it is not worth anything if it is broken and crumpled. In fact, it is an ancient stone thrower made using the principle of levers. Naturally, it is not much today, but it was a remarkable invention at the time.

With the help of the lever principle, the soldiers could throw boulders several feet high onto the city walls with very little effort, and even throw them over the walls into the city. The weight of the boulder combined with the high velocity inertia formed during the ejection was a disaster for an ancient city that was not yet mature and the walls were not very strong. If the angle of the projectile is right and the weight of the boulder is sufficient, a single stone projectile can even smash a large hole in the thick wall.

Since there is a thunderbolt, Cheng Pu is very happy. I don't go into battle shirtless, and I let the soldiers go around to collect and transport boulders every day, and throw them on the city wall of Hefei if there is nothing to do. If Liu Fu hadn't built the city wall of Hefei strong enough when he built the city, it is estimated that more than half of it would have collapsed.

At the head of Hefei City, Cao Hong looked at the official road in the direction of Jiangxia from afar, and his heart was very anxious. The messenger had sent Lu a few days ago, but the Prime Minister's reinforcements had just been delayed! Cao Hong, who is in a hurry, is about to get constipated!

Turning his face, Liu Fu stood next to him. Liu Fu also looked preoccupied. The heart said that if the prime minister's reinforcements don't come again, they will have to be stoned to death by the thunderbolt cannons of the Jiangdong Army if they don't get tired to death!

"Brother Yuan Ying! What are the casualties of our soldiers? Cao Hong covered his left arm where it had been injured last time. It's not all yet, I can't rest these days, and there is a tendency to deteriorate.

"The casualties are quite large, 800 killed, 1,000 seriously wounded, and the rest half are wounded!" Liu Fu's face was gloomy.

"Smack!" Cao Hong slapped the city wall in front of him, "Damn Jiangdong dog thief, don't let grandpa slow down, if grandpa slows down, he will have to skin this group of dogs alive!" ”

"The messenger has been on his way for seven or eight days, and I guess the day is long overdue! Why is there no news yet? Liu Fu muttered to himself.

"Hey, who said it wasn't!" Cao Hong looked into the distance, looking at his eyes and wanting to wear it!

"That's right! General! You said that although the production principle of this thunderbolt is not too complicated, if you don't understand the doorway, it will be very difficult to imitate it! Where did the Jiangdong military get the production method of this thunderbolt? "In the past few days, I have been smashed by the thunderbolt of the Jiangdong Army, and it is difficult to sleep. I really don't understand how the Jiangdong Army got the production method of the Thunderbolt cannon.

"Could it be that there are ghosts in the army?" Cao Hongyuan's eyes widened, and his eyeballs were about to pop out.

"I don't rule it out! At the beginning, the prime minister and Yuan Shao had been confronted for so long, and there were many Crouching Tigers, Hidden Dragons in the Yuan army, but even so, the production method of this thunderbolt cannon was not leaked. Where did these Jiangdong people get them? Liu Fu thought about it left and right, but he couldn't do it. Of course, Liu Fu could not have imagined that more than a thousand years later, there was something called "Baidu" that could search for complete thunderbolt drawings. And this drawing was just memorized by the young master Zhuge who had a heart.

"Hey~ Since Guo Fengxiao died, the eyes and ears in our army have become more and more rice buckets! It's completely lost from the style when it swept the Central Plains! The so-called "thinking about good generals in war, thinking about loyal ministers in national difficulties", at this time, even Cao Hong began to miss the founder of Cao Jun's spy agency, Guo Jia and Guo Fengxiao, who were known as "ghost talents".

"Yes! Guo Fengxiao is resourceful and strategic. It is a genius who comes once in 500 years, but God is jealous of the talent, and his ambition died young before he was paid! It's a pity! "Heroes cherish heroes, and Liu Fu also deeply regrets Guo Jia's death.

Here, Cao Hong's two goods on the city wall are sad and sentimental, and they don't care.

Let's say that the two guys Zhuge father and son are full of food and have nothing to do in the camp, which is really idle and painful. So he took out the military maps of Jingzhou and Yangzhou for a while.

Father Zhuge pointed to this and dotted that on the map, and looked at Young Master Zhuge who was also looking at the map on the side with a frown, and asked, "Zhan'er, who do you say our Prime Minister Cao Cheng will send if he sends troops to rescue Hefei?" ”

"Do you need to ask? Zhang Liaobei! Young Master Zhuge didn't raise his head and continued to study the map.

"Oh? Cao Cao has countless generals, why are you so sure of using Zhang Liao? Father Zhuge asked again.

Young Master Zhuge raised his head and said with a smile: "Dad, you test me again!" Hey, you're so bored! Hey, well! Then I'll analyze it! Young Master Zhuge hung up the map, pointed to the location of Hefei on the map and said: "Hefei is the gateway to the Central Plains, once Hefei is lost, the gateway of Xudu will be opened, and the Central Plains will be shaken!" The already restless pro-Han and anti-Cao forces are taking advantage of the trend, and Cao Cao's rear will fall into chaos. Therefore, our Prime Minister Cao Cheng will never put the safety of Hefei in disregard, and will definitely send a general to the rescue. However, Jiangxia is thousands of miles away from Hefei, and the infantry will definitely not be able to rush to help, so Cao Cao must use cavalry. It is true that Cao Cao's subordinates have countless generals, but if you want to talk about large-scale cavalry battles, then no one can compete with General Zhang Liao. This guy was a famous general in Dong Zhuo's army back then, when it comes to cavalry, which army can compete with the Xiliang cavalry in the world? So! Jiangxia is thousands of miles away, if you rush to help, you must use Zhang Liao! ”

"Yes! Hahaha! Stinky boy, you're about to find out all about this war! In a few years, Daddy won't be able to catch up with you! "Father Zhuge is quite pleased with Young Master Zhuge 's performance.
