Chen Xunbing sent a letter to Guguan to attack Luoyang, but he did not expect that the defenders of Luoyang had withdrawn a day earlier, and were now confronting Cao Cao in Guandu. Pen? Interesting? Pavilion wWw. ｂiquge。 It turned out that three days ago, Yuan Shao was forced to transfer troops and horses under the pressure of the Guandu front and temporarily gave up Luoyang.

Now, in Guandu, Cao Cao's 400,000 coalition troops are facing off against Yuan Shao, of which Cao Cao's soldiers and horses account for 290,000, Liu Bei 80,000, and Sun Ce 30,000. And Chen Xun also personally selected 30,000 elites to go to Guandu to help Cao Cao after taking Luoyang, not that Chen Xun didn't want to send more troops and horses to help, but the foundation in his hands was not yet stable, and he needed a lot of military support, he didn't want to repeat the mistakes of Luoyang back then.

Looking at Chen Xun who came, Cao Cao personally went out of the city to greet him, looking at the soldiers and horses brought by Chen Xun, Cao Cao's eyes were a cattle, and then he catered to Chen Xun and entered the camp.

Cao Cao's big tent can be regarded as a full hall at this time, Cao Cao's position is in the first place, and in the first seat next to Cao Cao, an elder with a white face and big ears is looking at Chen Xun with a smile, looking very charitable, this person is Liu Bei, the assassin of Xuzhou. At the bottom of Liu Bei, the heroic Sun Ce nodded to Chen Xun, and a handsome and elegant man standing behind Sun Ce also arched his hand at Chen Xun.

That man is Tai Shici who rescued Xuzhou back then, and it can be regarded as Chen Xun's old acquaintance, Chen Xun did not have enough qualifications to recruit this fierce general who is both civil and military, and now when he finally has the qualifications, the fierce general ran away with others, which can be said to make him sigh.

Chen Xun followed Cao Cao's gaze and sat down in the first position on the right side, and then asked with a smile, "Gong Cao, how is the battle situation now?"

Cao Cao sighed and said: "Yuan Shao's army built a city in front of our army, and then launched an attack every day, which made our army miserable. ”

Chen Xun frowned and said, "Can Yuan Jun go out of the city to fight?" ”

"No, I didn't."

Hearing this, Chen Xun's brows furrowed into a Sichuan character, and then he said slowly: "This matter will be handed over to me, and I will definitely come up with a way to break Yuan in three days." ”

Chen Xun had just come to Guandu, and if he wanted to gain a firm foothold, he had to make great contributions, and Yuan Shao's condescending tactics of deep ditches and high bases made Chen Xun think of a siege machine: "Catapult." ”

The current catapult should not be able to shoot above Yuan Shao's city pass, but the principle of the catapult Chen Xun is still very clear.

The catapult is a large manpower long-range weapon that uses the principle of lever to throw stone projectiles, as long as the height of the city wall built by Yuan Shao can be observed, and the catapult can be recreated with the principle of lever to reach the standard range.

At the front line of Cao's army camp in Guandu, it was already early in the morning, but Yuan Shaojun's offensive on the city pass was unabated, and the soldiers of Cao's army used each other's shields to resist the arrows shot by Yuan Shaojun, looking very tired.

"Ergouzi, you eat first, I'm in the way here." An old soldier took a wheat cake from his bosom and handed it to the little soldier beside him. It turned out that the soldier called Ergouzi was the son of this veteran, because he had to fight, so Cao Cao drew out a lot of young adults to go to the battlefield, and this soldier named Ergouzi was one of them.

Ergouzi took the wheat cake from the veteran's hand, with a happy and sluggish smile.

The second dog opened his mouth and wanted to take a bite on this round wheat cake, but found that there seemed to be something more on his face. The veteran fell on Ergouzi's body, and that bit of thing was really the blood of that veteran, that is, Ergouzi's father.

"Daddy!" The second dog let out a roar, then raised the long shield in his hand and rushed under the gate, and the result was obvious, the second dog was shot into a sieve.

"Shoot the arrows." Above the city pass, another loud sound sounded, only to see the sky of rockets shot down from the city pass, although the soldiers of the Cao army also hurriedly raised their shields, but also suffered heavy casualties.

Looking at the dead Cao Jun soldiers, Chen Xun, who was in the distance, secretly analyzed the range of Yuan Jun. Chen Xun also saw the matter of the second dog, but it did not cause a little fluctuation in his heart, fighting a war will kill people, and being a soldier is fate.

Chen Xun returned to his camp, and then called Sima Yi, who had been staying by his side, the so-called one-person plan is short, with such a good mind as Sima Yi, how can he let it go.

After briefly explaining the principle of leverage, Sima Yi looked at Chen Xun, there was something else in his eyes, and Sima Yi immediately knelt down on the ground and said, "The lord is really a god and a man." ”

Years of experience have made Chen Xun's face extremely thick, and he said lightly: "Zhongda, do you have any new ideas?" ”

After understanding the principle of leverage, Sima Yi's small universe also began to explode, and the various ideas he proposed made Chen Xun stunned, and then, after a sleepless night, the improved version of the trebuchet was launched, Chen Xun handed over the drawings to Cao Cao, and Cao Cao also began the production of trebuchets. Chen Xun knew that as long as this improved trebuchet came out, Cao Cao would inevitably go to plagiarize, so it was better to give the design to Cao Cao directly, so that Cao Cao could owe himself a big favor.

Two days later, Yuan Shao's soldiers were still showing off their might above the city pass, and Cao's soldiers were still passively beaten in the same place, but when the trebuchets were pulled up, a great change occurred.

The garrison of Yuan Shaojun above the city pass sneered when he saw the trebuchet that was pulled up, because he knew that it was impossible for the trebuchet to be able to throw stones into the city, although these trebuchets were larger than the average, but the guard did not think that he could add much range. When the trebuchets were fired together, the guard was blinded, and so were his Yuan soldiers, because the stones were thrown too far, and almost all of them could be thrown at the city pass.

In the face of the fierce attack of the trebuchet, Yuan Shaojun also complained bitterly, and finally could only retreat ten miles with a large army.

After Yuan Shao's army withdrew, Cao Cao's eyes looking at Chen Xun were obviously a little wrong, but he was still very kind and respectful on his face, and Liu Bei and Sun Ce's eyes were also different.

When Yuan Shao's Chengguan army returned to the base camp, Yuan Shao's face was also very unsightly, and at this moment, a majestic general stood up and said: "The last general Yan Liang is willing to be the vanguard." ”

Looking at Yan Liang, who was asking for battle, Yuan Shao's eyes showed a hint of joy, and said: "Since General Yan Liang wants to go to war and make meritorious contributions, then I will wait for the general's good news." ”
