It is impossible for Zhao Yu to return to Guandu in a short period of time, and it is impossible for Lu Ren to be in the camp every day without doing anything but waiting. Besides, Zhao Yu's volunteering to find out the news was an accident by chance, and it was not in Lu Ren's plan at all, and Lu Ren had prepared other excuses for this in order to stay on the Guandu battlefield to see if there was a chance to take revenge.

According to historical data, Cao Cao was "a joint battle, unfavorable" at the time of the Battle of Guandu. When the public soldiers were less than 10,000, the wounded were twelve or thirteen", "the public and Shao refused to fight each other for months, although they were killed in battle, but the people were short of food, and the soldiers were tired. The public said that the transporter said, 'But the fifteenth day is for you to break the Shao, and you will not work again'. Later generations generally believed that Cao Cao was mainly out of grain and grass at this time, but some scholars pointed out that in addition to the problem of grain and grass at this time, there were also very important problems plaguing Cao Cao, that is, the soldiers under his command were too tired and had reached the verge of collapse, and it was very difficult to replenish the source of soldiers.

Whether Cao Cao's grain and grass are really difficult to support, I'm afraid it's really hard to say. And Lu Ren once calculated a half-confused and half-clear account after a few years of confusion, that is, if Cao Cao was based on the original situation, would it be really so difficult in terms of grain and grass when he fought the battle of Guandu.

The reason why it is said to be half confused and half understood, the reason why it is understood is that Lu Ren has been mixed for several years and has practical experience in all aspects, while the confusion is that some things are not clear, and can only be random speculation. For example, during the period from Cao Cao's coercion of Emperor Liu Xie's relocation of the capital to Xuchang to the battle of Guandu, he was almost constantly fighting, and the amount of grain and grass consumed was incalculable. Moreover, Cao Cao has suffered several defeats, and the military supplies are not lost at all, so how can this account be calculated?

Anyway, Lu Ren later calculated the approximate result. When Cao Cao attacked Wuchao, there should still be a certain amount of grain and grass reserves in Xuchang's warehouse, not like the historical materials say, "only this month's grain", otherwise Cao Cao's fields in the past few years will not be in vain? The sentence "It's more than a million years old" doesn't seem to be fake, right?

Of course, Lu Ren's calculation of this is not meaningless, when he is full, he has nothing to do. Lu Ren has always been very worried that due to the appearance of his own outlier figure, Cao Cao will have enough food and grass during the Battle of Guandu, and as a result, Cao Cao will not have to take a bold gamble like the original process. And after calculating such an account, I have a certain bottom in my heart. Lu Ren focused his attention on the two things of "the twelfth and thirteenth of the wounded" and "the fatigue of the soldiers". In other words, Cao Cao will be bold, not just because there is not enough food and grass. But the combination of various factors made Cao Cao have to take a bold shot.

In terms of food and grass, Lu Ren has actually helped Cao Cao solve it, but as for the "Twelve and Thirteen Wounded" and "Fatigue of the Soldiers", Lu Ren cannot solve them. But now Lu Ren can just take advantage of these two questions. Give yourself an excuse to stay in Guandu.

"The 12th and 3rd of the wounded" is a problem in terms of the source of soldiers. Of course, later generations have pointed out that this is too exaggerated, and it is singing praises for Cao Cao, but Cao Cao's strength is tight, but it is a sure thing. Lu Ren didn't know how to sprinkle beans into a soldier, and there was no way to make the military service population in Cao Cao's subordinate territory increase greatly within a few years, after all, there were so many people at that time, even children needed a corresponding amount of time to grow up.

But one thing Lu Ren can do is to make a "field hospital" to treat Cao Cao's wounded soldiers here. Generally. This thing seems to be a drop in the bucket, but Lu Ren has been mixed up for a few years. It is clear that the people who really died on the battlefield in the war at that time were often not very many, but more died from those wounds and infections. So to get a field hospital, Cao Cao's existing combat effectiveness can be maintained more or less, at least not so badly. Besides, I have done it when I fought Lu Bu in Xuzhou before, and now I have some relevant experience when I do it again, and I can prepare in advance, and I will not be as busy as when I was in Xuzhou.

As for "soldier fatigue", this Lu Ren really can't solve it. However, to appease the morale of the army and stabilize the morale, Lu Renzhi believes that he can do something. After all, Lu Ren has done a lot of this kind of thing, and he has the corresponding experience. Besides, Lu Ren is now the "immortal master" in the mouth of the Qingzhou army, and it is not an exaggeration to say that he is the sect leader in half of the faith. And because the spiritual power generated by faith is often very terrifying, Lu Ren has read some information in this area and knows how powerful this spiritual power is. And now at this time, Lu Ren doesn't mind playing a trick on himself to give these soldiers some spiritual "energy".

And with these two things, Lu Ren believes that as long as he makes a little bit of results, Cao Cao will not drive himself back to Xuchang. As long as you can stay on the battlefield in Guandu, you can make corrections to the battle situation in time. For example, if Xu You didn't come to Cao Cao, then he would have to remind Cao Cao of the information about the black nest. And what he did to the food and grass, the wounded, and the morale may itself affect Cao Cao's mentality, so that Cao Cao will no longer be bold, so it is more necessary for him to stay in Guandu and correct Cao Cao's mentality in time.

Therefore, after Zhao Yu set off and Lu Ren didn't let himself worry for the time being, Lu Ren began to prepare the things he had prepared before, such as setting up the "field hospital" as soon as possible, don't just eat dry food in the camp every day and wait.

This so-called "field hospital", Lu Ren still took a little effort. In fact, not long after Wan'er's death, before Lu Ren was transferred to Xuzhou, Lu Ren had already started preparations, and as for the excuse, it was also very easy to find, and then through his relationship with Emperor Liu Xie and Hua Tuo, please ask Emperor Liu Xie to casually issue an edict and send Hua Tuo to train a group of surgical personnel. In terms of personnel, it is easy to find, young and strong men are not easy to deploy, but the job of a nurse is originally suitable for women and women, and with the conditions at hand in Lu Ren, it is not too simple to recruit a group of women and women as nurses. And Emperor Liu Xie directly waved his hand and transferred two hundred palace maids to Lu Ren.

Speaking of which, at that time, Lu Ren originally wanted to personally go into battle to teach some modern health knowledge to the personnel, but he was unexpectedly transferred to Xuzhou, and the personnel training had to be handed over to Hua Tuo, but many related health knowledge and things such as training methods, Lu Ren still handed over to Hua Tuo in writing, and asked Hua Tuo to do those things. Hua Tuo did not disappoint Lu Ren, and by the time Lu Ren came back from Xuzhou and inspected, these personnel were all presentable. Although it cannot be compared with the field hospitals of later generations, it should be said that it was excellent at the time. Besides, Hua Tuo's surgical ability is an ornament?

The last time he came to Guandu, Lu Ren didn't bring them because he had to make the final adjustments to these personnel, and he officially brought them over when he came back to Guandu. And now if you get a "field hospital", it is not an exaggeration to say that it has an immediate effect. Again, in that era, being injured on the battlefield is actually far more troublesome than dying in battle, and the actual effect of Lu Ren's "field hospital" is actually not very good, and the medical capacity is very limited, but after alleviating the pain of the soldiers to a certain extent, the impact of psychological factors is obvious.

You must know that for many Cao Ying's soldiers, Lu Ren's name as an "immortal master" can be calmed down, and there is another thing that Lu Ren himself finds funny but not difficult to understand, that is, these old men who have fought in the dark can ...... with beautiful women when they are recuperating from their injuries and resting Let's say that they are all beauties, anyway, at this time you can chat with women, or even just watch the women's postures writhe, which is also very helpful for relieving tension.

And when Lu Ren saw this situation in his busy time, he couldn't help but sigh secretly in his heart: No wonder in the hearts of men in later generations, nurse sister paper always has a place on the list that he wants to push down the most. This kind of mentality is not necessarily evil intentions, most of them still have an element of admiration for these "angels"?

Cao Cao originally wanted to reprimand Lu Ren by bringing a bunch of women and women, but first, he saw that the effect of this "field hospital" was good, and the wounded were the source of soldiers after treatment, which slightly relieved the urgent need; Second, Cao Cao didn't expect that this thing could stabilize the morale of the army, and there were still some women in the military camp at that time, so Cao Cao simply turned a blind eye in the end, and just told Lu Ren to manage discipline.

Back to Lu Ren, after Lu Ren's daily busyness, he usually sat there and stared stupidly in a certain direction. Later, I don't know which brave guy actually begged Lu Ren if he could play music...... It was only at this time that Lu Ren suddenly realized that he hadn't played music for a long time, and music had a soothing effect on many occasions.

As a result, every time night falls, the sound of Lu Ren's calm flute music will be heard in the "field hospital", and the soldiers and soldiers of Cao, who have been busy all day, will find a temporary peace in this flute music. The big effect may not be, but at least it will allow these soldiers to sleep a little more peacefully at night...... Lu Ren himself jokingly called this a "spiritual cigarette". Don't underestimate cigarettes, in later wars, soldiers often smoke when they have time. They are often not really addicted to smoking, but in the drift of smoke, they will find an indescribable and unexplained psychological comfort......

――――――――――――――――――――

In a blink of an eye, more than half a month has passed, and Lu Ren has nothing to do, so he looks into the distance at the camp gate, hoping that the figure of Zhao Yu, the little girl, can appear in sight. And Cao Cao didn't know when he also came to Lu Ren's side and looked into the distance with Lu Ren.

Cao Cao's eyesight is better than Lu Ren's, and when he chatted with Lu Ren without a word, he suddenly seemed to see something, and took out a telescope from his waist pocket with his backhand to look into the distance, and after a while, Cao Cao laughed and said, "Finally back!" If Miss Zhao doesn't come back, I think Yihao and you will all go crazy. ”

Lu Ren was stunned and said, "Ming Gong, you haven't seen Xiaoyu!" ”

Cao Cao said with a smile: "Lonely doesn't know Miss Zhao, but the Jedi she stepped on is a lonely love horse, how can she not know?" ”

"Oh......"

Lu Ren slapped his head, and said in his heart that I was confused. At that moment, he also looked into the distance again, only to see a black dot gradually approaching, and after a while, he had rushed to the front of the walled gate, it was Zhao Yu and Jedi who were covered in dust!
