On the second day of October, Officer Cao crossed the camp.

Compared with when he had just encountered Dong Cheng's rebellion at the beginning of the year, Cao Cao looked much older in just over eight months.

Theoretically, in the past eight months, he has only grown from 45 to 46 years old.

And because he has been lustful for a long time, is in a happy mood, and has a very comfortable pressure discharge, Cao Cao, who was originally forty-five years old, looks like he is forty at most, which is very young.

But Cao Cao, who is now forty-six, has white spots in his hair and wrinkles on his face, and looks at least in his fifties.

Eight months of high-intensity stress resistance, anxiety and recession are far beyond what ordinary people can bear, even if they have steel nerves, the axe and chisel of the years will be reflected in the flesh.

In recent days, Yuan Shao's new offensive has once again made Cao Cao's nerves extremely tense, and he urgently needs to find a new way to break the move.

With the end of another day of fighting, a group of strategists and several generals in charge of patrol came to the Chinese army's big tent to report today's results and casualties, and by the way, asked for follow-up battle plans.

After Cao Cao listened, he nodded for a while and shook his head for a while, and finally just commanded helplessly:

"Originally, I actually learned to use Ge Gongcha, and there are improved wells that can supplement crossbowmen with protective ladders on the battlefield to launch a tough battle, and they are becoming more and more decent. After half a year of bloody battles, the original brother has made a lot of progress, is this the third or fourth time to surprise Lone?

The soldiers were instructed to continue to work day and night, raising the rammed earth camp wall - building the wall was not the main purpose, it was only incidental, the main thing was to find a place to go for the excavated soil.

Lone wants to continue to widen the long trench used to cut the exit of the Hebei Army's tunnel, and there is no need to increase the depth. When the enemy army is attacking, it is impossible to directly lay a trench bridge and drive through the ditch! So that Ge bus can't be pushed to the rammed earth camp wall! ”

Cao Cao's order was also a helpless move. Because in the past half month, as Yuan Shaojun has upgraded his offensive methods, he must break the move at any cost.

If Guandu's side was the kind of siege warfare that was surrounded, Cao Cao would have been in danger when Yuan Shaojun pulled out Ge's carriage and climbed the rammed earth wall to fight Cao's army hand-to-hand for the first time.

But fortunately, the situation here is not a siege battle, but an offensive and defensive battle at the camp pass, and Cao Cao has a way to reinforce the friendly army.

So even if Yuan's army went to the wall, the two sides would just change the battlefield and engage in fair hand-to-hand combat.

Sergeant Cao kept fighting and still withstood it for several days. It's just that the rate of blood loss from casualties every day is very fast, and it becomes a meat grinder.

If it continues like this, it won't take a month for Cao Jun to be completely defeated by Yuan Shao.

At this moment, Cao Ren and Xiahou Yuan, who were in charge of guarding the camp, couldn't help but remind Cao Cao after listening to Cao Cao's solution: "Ming Gong! We can't afford to consume the lives of soldiers like this anymore!

Since our army built a thunderbolt car to confront Yuan Junjing's chariot, although Yuan Junjing's chariot did not dare to force too close to shoot at the pass, it relied on its high and steep retreat to more than 200 steps away from the camp wall, and still could watch the movement of our army.

Now that they have been holding each other for a long time, the enemy's fortifications outside the gate have become stronger and stronger, and the rattan shields and array houses have been erected within 100 steps in front of the formation. Our soldiers go out of the camp to dig wide trenches, they will definitely be discovered by the enemy, and then throw them with bows and crossbows, and the soldiers who dig wide trenches will inevitably suffer casualties! Our troops are already stretched, digging a ditch and killing people, I'm afraid that our morale will soon be exhausted! ”

Cao Cao was distraught when he heard this, he didn't know about these difficulties, but he knew the priorities even more. In the face of Xiahou Yuan and Cao Ren's persuasion, he still tried his best to disagree:

"I don't know this truth! But the trench digger can carry a rattan shield on his back and chop the door panel, and bow down, and under the trench, the enemy will inevitably not be able to directly aim and shoot. By throwing arrows that fall down, casualties won't be fast!

But if the Yuan thief's Ge bus leaned against the camp wall again, and hundreds or thousands of people poured up to fight hand-to-hand, I am afraid that most of the casualties of our army would not take half a month! ”

Cao Ren: "But if you defend the camp wall, the good thing is that both sides have casualties, and our army takes a defensive position, and the casualties can be smaller than Yuan Shao." The soldiers who went out of the customs to dig wide trenches and traps were consumed by Yuan Shao's projectiles in vain, and even though the losses were slower, it was too demoralizing to be beaten in vain if they couldn't fight back. ”

Cao Cao: "Then find other ways to boost morale as much as possible!" The key now is not that morale can't hold up, but to save the lives of more soldiers and delay for change! I also doubted for a while that our army would be able to hold on, but Wen Ruo sent a letter from Xu Du yesterday and encouraged me to say:

Yuan Shao's martial arts factions are very numerous, and the internal struggle is fierce, as long as he can't overcome it for a long time, he will inevitably pass the buck internally, and take the credit, this may be our only chance! It is impossible to win a war of attrition, what we want is to delay it for a longer time and wait for a turnaround! ”

Hearing Cao Cao say this, and also relayed Xun Yu's opinion in the letter, the generals did not object anymore, and they also realized that the battle situation was indeed the case.

If you drag it out until the end, you may not be able to live, but it will definitely be dead. In that case, why bother to seek death.

And Cao Cao also understood at this moment: the tactics are ever-changing, the technical means are also ever-changing, and it is impossible to predict what moves the two sides will make in the future.

There is only the relationship of interests, the relationship between friend and foe, and the internal contradictions between the two sides, and these things are consistent. There are many factions and intrigues within Yuan Shao, which Cao Cao knows.

Even if Zhuge Jin sits in Cao Cao's position today, he has to admit that interests are eternal, and the contradictions arising from conflicts of interest are also eternal. What advice Xu You will offer to Yuan Shao, and whether Yuan Shao will use it, these may be changed because of the butterfly effect brought by Zhuge Jin, a traverser.

But there is one thing that Zhuge Jin, who is thousands of miles away, also knows, that is, the infighting between the trial and Xu Youhui, the Hebei faction under Yuan Shao and the infighting between the foreign faction, which is eternal.

No matter how many new technologies and tactics emerge, this contradiction is irreconcilable.

……

Cao Cao issued the latest delaying tactical instructions, and Cao Ren and Xiahou Yuan continued to carry them out, and in the next day or two, the casualty rate of Cao's army really decreased, but at the cost of Yuan Shaojun's casualties falling even more.

Because the trench was widened, the Ge bus could not get up and could not start hand-to-hand combat, so he simply retracted behind the fortifications of the vine shield array and threw cold arrows. Yuan Shaojun's arrows and material consumption rate increased greatly, but he didn't need to kill any soldiers, but he could shoot more than 100 Cao soldiers who were digging at the bottom of the ditch every day.

This is still the case that Cao Bing generally carried the door panel on his back, so Cao Cao quickly realized that this work should not be done by the soldiers, or even by the auxiliaries.

It should be in Chenliu County and Chen County to catch the people and the people on the spot to do it, anyway, it is to dig the soil, and everyone will do it. Being shot to death by Yuan Shao hundreds of people in vain every day, Cao Cao can afford this loss, and his collapse time can be delayed from more than half a month to two months - of course, the premise is that there is enough food, which is another shortcoming.

Two days after switching to the new tactics, Cao Cao finally ushered in the first turnaround.

On this day, Xun Yu of Xudu sent fast horses and escorted several envoys and craftsmen from the rear. Xun Yu specially endorsed these people, saying that these people were sent by Zhou Yu of Wu County.

Their suggestions are very important, Xun Yu has been urgently verified in Xudu, please Cao Cao pay attention to it and meet immediately.

Of course, Cao Cao absolutely trusted Xun Yu, so he immediately met with the envoy - of course, before the meeting, he still had to search his body thoroughly, and let them talk about things twenty steps away, and Cao Cao would stand by Xu Chu anytime and anywhere.

After Zhou Yu's envoy met with him, he immediately showed Cao Cao a bunch of drawings, as well as some application notes written by Zhou Yu.

Cao Cao saw Chen Deng's tactics in the defense of Guangling, the tactics of dealing with Ge Gongche, and some other applications and feature descriptions and appearance drawings of new equipment during the confrontation between Sun and Liu.

"These things are all the experience gained by Sun Ce's fierce battle with Guan Yu and Zhuge Jin in April and May, and the loss of 20,000 or 30,000 soldiers and horses? Zhou Yu summed it up in July, why did he send it now? And why didn't Zhou Yu pay so much attention to it, Pyle and other unknown people sent it! Cao Cao was very unwilling, and hurriedly asked the messenger.

He thought it would be nice if it had been delivered a month or two earlier! He can definitely kill thousands of elite soldiers! If injuries are also counted, it is the saving of more than 10,000 living forces! Yuan Shao's consumption of ground meat these days is too terrifying!

Zhou Yu's envoy was a little decadent but replied forcibly and calmly: "Governor Zhou has already sent several groups of people to send them, and the first few groups may have been intercepted and killed by Guan Yu. How can such a life-or-death thing be done by a person whose life is precious? ”

Cao Cao was slightly moved at this time, and his brain made up for the dangers along the way.

Facts have proved that taking advantage of Sun Ce's remote location and blocking news is effective. But only if the message is "time-sensitive".

If it is an unbreakable truth, eternal and effective, and without timeliness, then the blockade can only be delayed, not sealed.

No matter how strong Zhuge Jin is, he will only kill all the envoys sent by Zhou Yu a month or two ago, and there will definitely be a time when it will leak through in the end.

Cao Cao realized that the merit of the person who came was not small, so he asked Corporal Lixian: "Dare to ask the name?" What is the official position? ”

Zhou Yu's envoy replied: "The last general, Zhou Shan, is only a tun commander in the army, but Sun is a rebel general who is from a personal guard. ”

Cao Cao immediately ordered: "Lonely, you will be named the military Sima to show the merits of nine deaths and a lifetime." If you only look at your merits, it may not be worthy of such a reward, but for the sake of the group of envoys who died in front of you, they can no longer be promoted, and you can only receive it on your behalf. However, in the future, if they are found to be alive in Wuhui, Lone will reward them with a lot of money. ”

After Cao Cao finished speaking, he threw a few drawings to the several strategists who accompanied the army, and asked them to find skilled officials and craftsmen in the army who were good at craftsmanship, and quickly verify and build, and read Xun Yu's verification results by the way, so as not to make detours.

The construction potential in wartime is always endless, and under the pressure of the life and death crisis, Cao Jun has advanced all the work at a rapid pace, and has also concentrated the bed crossbows in the army and the rear, and imitated Chen Deng's tactical equipment and deployment of Zhou Yuge's bus overnight.

Cao Jun's equipment and technical content were not as good as Liu Beijun's, but Cao Cao was also forced by the actual situation to draw inferences a little, and thought of some ways to make up for it - for example, he noticed that outside the wall of his Guandu Dazhai Pass, there was already a long trench to defend Yuan Shao's tunnel tactics, and it has been digging wide recently.

So Cao Cao had an idea and asked the soldiers to give up further widening and instead let Yuan's army refill the position of the cart when it attacked.

However, Cao Cao leveled the soil near the trench and deliberately built a gentle slope that could not be seen.

In this way, the Ge bus will be more laborious to push uphill, and the body will be slightly tilted back, and the center of gravity will be more unstable.

In short, in order to survive, Cao Cao racked his brains for all the tricks he could think of.

And compared with the same period in history, Cao Jun has a greater advantage, that is, Jia Xu, the old yin ratio, was also forced by Cao Cao to die because of Cao Cao's propaganda operations during the Dong Cheng Rebellion-

Jia Xu in history only persuaded Zhang Xiu to surrender to Cao Cao, and then he realized that his merits were enough to save his life, and then he began to mess up, at least he didn't help Cao Cao with specific tactics and strategies during the Battle of Guandu.

But now Jia Xu has become "the culprit of the second attempt to kill Emperor Han Xian's second attempt to punish the thief and pro-government", Jia Xu knows that as long as Cao Cao does not cover him, he will be cut in half by the car in the hands of any other person, so he has to go all out and die.

There is one more Jia Xu who did his best than the same period in history, and Cao Cao is enough to make up for the losses of Cao Chun, Wang Bi, Hou Cheng, and Liu Yan.

With the concerted efforts of all the people and their best ability, the means of resisting Yuan Shao's new technological offensive finally gradually took shape.
