It's just that at the moment, it is easy for him to capture Kei Pass and prepare to destroy Yue, if he returns to Hangu Pass, won't the overall strategy be broken. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

If you don't come back to help, and you are afraid that the war at Hangu Pass will be tight, and Lan Yu will not be able to stop Cao Cao's troops.

Just when he was in a dilemma, Li Si on the side smiled faintly: "King Zhou, don't worry, there is a plan to kill two birds with one stone, which will not delay the plan to destroy Yue, but also alleviate the danger of Hangu Pass." ”

...

Hanya Kansai.

50,000 Zhao troops, stationed outside the city, the banner covered the sky, and the momentum was huge.

In front of Hangu Pass, tens of thousands of Zhao troops were shouting and fighting, looking at the empty stone bullets shot at Hangu Pass, roaring excitedly.

Nearly 500 trebuchets have been towering in front of the pass, and are carrying out an endless onslaught on Hangu Pass.

These 500 trebuchets are not ordinary trebuchets, but Liu Ye dedicated them to Cao Cao, and the improved trebuchets, called the Thunderbolt, are comparable to the Zhou army's heavenly thunder cannons in terms of power and range.

Looking at the dusty Hangu Pass, Cao Cao squinted his eyes and sneered, and said: "Zhang Yuan, your heavenly thunder cannon crisscrosses the Central Plains and breaks through how many cities, and today this king will also let you taste the taste of my thunderbolt." ”

"Report," the rebuke rushed to the point, and arched his hand: "King Yu, the partial division of General Xia Wen Miaocai has gone down the Chenghe River to the east and landed in Chengyin City, and the enemy general Lan Yu was forced to divide 5,000 troops to block, and the number of defenders of Hangu Pass has been sharply reduced. ”

"Okay, it's worthy of being a genius in my family." Cao Cao was overjoyed, raised his whip and pointed at Guancheng, "Bombard for half a day, and then the whole army will attack together, within three days, we must break through Hangu Pass for this king and take Luoyang." ”

Cao Cao was high-spirited, and tens of thousands of Zhao troops were also high-spirited, and their fighting spirit was even stronger.

"I heard that Yuan Shang and 50,000 Hun soldiers and horses have almost chased Zhang Yuan out of Hanoi County, if my big Zhao captures Luoyang again, then Zhang Yuan and Lianghe will be in an emergency, and it will be a matter of time before they collapse on all sides." Liu Ye smiled faintly.

Cao Cao smiled and praised: "If it weren't for Ziyang's dedication to this thunderbolt, this king would not be able to successfully capture Hangu Pass. ”

"Ye is just doing his best, don't dare to take credit." Liu Ye was busy and said humbly.

Cao Cao laughed, and his spirit was high.

"Although the Hun iron cavalry is strong, Yuan Shang and Yu Fuluo's ability to use troops is far from Zhang Yuan's opponent, and I think that we should not be too optimistic." Guo Jia remained a little calm.

The voice fell, and another horse rushed over, and exclaimed: "King Zhao, Zhang Yuan used a fire ox to defeat the 50,000 iron horsemen of the Huns in Xiuwu, Yuan Shang was defeated and fled from Jiguan, and Yu Fuluo has been killed by him. ”

A thunderbolt crashed down on the heads of Zhao Guojun's ministers.

The spirit on Cao Cao's face was shattered in an instant, and Liu Ye and other ministers were all stunned.

Even if it was Guo Jia, surprise immediately appeared on his pale face.

Just when Cao Cao's ministers were not frightened, another horse rushed to the palace and shouted: "King Yu, Yuan Shang abandoned the Kei Pass, Zhang Yuan's army took the Kei Pass without blood, and went all the way west into the east of the river, and captured Puban City by surprise. ”

"What," Cao Cao's body shook violently, he couldn't sit still anymore, and grabbed the information to look at it urgently.

The sphere of influence of Guanzhong and Yuan Shang is bounded by Chenghe, Guanzhong in the west, and Yuan Shang's sphere of influence in the east.

This section of the river flows from north to south, the water potential is turbulent, the mountains on both sides of the bank are undulating, the birds are difficult to cross, only the first line of Pubancheng to which Hedong County belongs, the water potential is slower, the terrain is more flat, and it can barely be crossed.

The east of the Chenghe River is Pubancheng, which belongs to Hedong County, and the west of the Chenghe River is the Pubanjin Ferry, which belongs to Fengyi County in Guanzhong.

A county in Hedong originally belonged to the territory of the Southern Xiongnu, Cao Cao had been married for many years, and the Huns were used as the Hedong barrier, so Cao Cao's troops were mostly stationed in the first line of Tongguan Hangu Pass, and the first line of Puban was not his key defensive area.

Cao Cao never expected that Zhang Yuan would be able to destroy the main force of the Xiongnu with a fire bull array, scare away Yuan Shang, and capture the empty Hedong County all the way, and take Puban City by surprise, directly threatening his Guanzhong lair, how could he not be shocked.

"The 50,000 iron horsemen of the Huns were destroyed like this, I heard that the Fire Ox Array has been lost for a long time, how could Zhang Yuan be." Cao Cao looked at the information in his hand with a look of disbelief.

Guo Jia hurriedly said: "King Zhao, the matter has come to this, looking at Zhang Yuan's intentions, it is clear that he has changed his strategy, under the pretext of destroying Yue, but he wants to take the opportunity to kill my Da Zhao after Pu Ban enters the middle side of my pass, without further ado, please send reinforcements back to Pubanjin to defend it, and do not let Zhang Yuan cross the river." ”

Liu Ye was also busy saying: "What Feng Xiao said is very true, now that the cold winter has arrived, in a few days, the river will be frozen, and at that time Zhang Yuan's soldiers and horses can directly cross the river by stepping on the ice without boats. ”

Cao Cao's body shook again and again, and finally came to his senses, such as ordering Ma Chao and Yang Ding to ride forward with 10,000 steps, and go to Pubanjin to deploy defenses in the starry night.

When reinforcements were sent, Cao Cao breathed a sigh of relief, and Jiao Cheng's face gradually regained his calmness and coldness.

His gaze shot to Hangu Pass again, and a sneer rose at the corner of his mouth, "Zhang Yuan, do you think that if you take Puban City, you can force me to give up attacking Hangu Pass, hmph, this God-given opportunity for the five countries to unite to destroy Zhou, how can this king give up easily, this time, I Cao Cao will not recapture the Central Plains that belongs to me, I will not give up,"

When Cao Cao's reinforcements hurried to Pubanjin, Zhang Yuanzheng led the main army and attacked along Fenshui in the direction of Yueyang.

The capture of Pubanjin was nothing more than 10,000 partial troops led by Xiao Maha, under the banner of his King of Zhou, pretending to attack Guanzhong, the purpose was nothing more than to force Cao Cao to divide his troops and return to the defense, so as to reduce the pressure on the Lanyu line of Hangu Pass.

Zhang Yuan did not have enough rafts to let his 90,000-strong army cross the river and attack Guanzhong, so he could only wait until the river was frozen and crossed the river on ice.

And by that time, Cao Cao must have built a strong fortification at Pubanjin on the other bank, and even if the army can cross the river smoothly, it may not be able to attack Guanzhong.

Moreover, in case Li was in a hurry and led the army to retreat, Zhang Yuan would have to fight Cao Cao, a strong man, head-on.

Cao Cao is not as easy to bully as Yuan Shang.

Zhang Yuan's strategy has not changed, and he still wants to kill his nephew first.

On the side of Yuan Shang, in order to prevent the Zhou army from moving north, at the suggestion of Sima Yi, he cut down trees everywhere and destroyed earth and rocks to fill the mountain roads in Vietnam, delaying the northward movement of the Zhou army.

In order to guard against Zhang Yuan's heavenly thunder cannon, Yuan Shang ordered that the passes along the border should be strengthened with mountain stones to increase their solidity.

In order to resist Zhang Yuan, Yuan Shang can be said to have used all his slackness, no matter how Ruzhong wants to block Zhang Yuan's troops in the south of Yueyang.
