What is Oil?

According to modern society, oil is the blood of industry. Pen? Interesting? Pavilion wWw. ｂiquge。 infoAnd in the modern world, what country is without oil...... Then hehe.

Lu Renke has been leading Yizhou to the road of industrial development, and Yizhou has been officially established in the twelfth year of Jian'an and included in the territory of the Han Dynasty, and it has been eleven years now, plus the development period of the years before the establishment of the state, it has been nearly 20 years now.

Twenty years, not too much, not too little, at least under Lu Ren's painstaking management, now Yizhou has a very good industrial base at that time. If oil is obtained on this basis, the industrial development at hand of Lu Ren can enter a new stage.

Of course, those things can't be completed in three days or two days, and even if Lu Ren and Shirley have ready-made information, many related things still need time to be sorted out. Not to mention anything else, just the refinery is going to be built, which is enough for Lu Ren and Shirley to be busy for a while.

Time passed day by day in such a busy situation, and soon came to the beginning of the twenty-fourth year of Jian'an, and the battle between Liu Bei and Lao Cao finally started at this time.

If it is according to the original history, Liu Bei should have launched the battle for Hanzhong in the middle of the twenty-third year of Jian'an. However, due to a series of changes brought about by Lu Ren, an outlier figure, Liu Bei's launch of the Hanzhong battle was delayed for about half a year.

Here is also a brief introduction to the current situation. First of all, on Lao Cao's side, Lu Ren made a lot of trouble for Lao Cao, so Lao Cao had to spend a lot of time and effort on the "pruning" of the "flowers and plants" in his backyard, and this was also earned by Liu Bei Some time to make the preparation work more sufficient. Therefore, although Liu Bei's attack time was delayed by about half a year compared to the original history, it basically had no negative impact on Liu Bei's side.

Then there is the Jingzhou side. The biggest variable here is that Zhou Yu is not dead, and he has been eyeing the southern region of Jingzhou held by Liu Bei in the area of Chaisang and Baqiu, and Liu Bei also had to leave a group of elite soldiers to guard against Zhou Yu in Jingzhou, among which Zhuge Liang, who can deal with Zhou Yu, has always stayed in Jingzhou.

When Liu Bei entered Chengdu, he originally wanted to transfer Zhuge Liang to Shuzhong to preside over the internal affairs of Shuzhong, but after thinking about it again, he still didn't dare to do so. There's no way, Zhou Yu is not such an easy master to deal with. In addition, Zhuge Liang and Lu Su were the most staunch "coalition factions" among the Sun and Liu families, and leaving Zhuge Liang in Jingzhou to keep in touch with Lu Su would also help to maintain the alliance between the Sun and Liu families.

And Lu Ren also played a little trick here in Jingzhou. Lu Ren has a Guiyang City at the southern end of Jingzhou, on the surface, Lu Ren said to Sun and Liu's family that there are no other troops in Guiyang except for the necessary security and security forces, and whoever of you two wants this Guiyang City can just come and take it, but where do Sun Quan and Liu Bei dare to reach out to Lu Ren's Guiyang City? If this provokes Lu Ren, and then joins forces with another family, the trick of the one who does it will have to get out of Jingzhou, not to mention that the Sun and Liu families still have an already increasingly close trade relationship with Lu Ren.

Ruthlessly cut off trade relations with Lu Ren? Yes! But if you don't buy it, the other one will buy it correctly, and the strength will gradually widen the gap because of this. When some of the gaps get bigger and bigger, then it's a sure thing to suffer a big loss. And Liu Bei and Sun Quan are both smart people, where would this happen? So for Lu Ren, they also love and hate, they can only watch Lu Ren make a lot of money between the two of them, but they still have to greet Lu Ren with a smile. In a word, the plan of mutual checks and balances that Lu Ren formulated at the beginning can be said to be quite successful at this time.

It is precisely because of the success of mutual checks and balances that although Lu Ren did not leave any soldiers and horses in Guiyang, he has become the most peaceful place in Jingzhou. Lu Ren's hands and feet at this time were to send words between the markets, that is, if there was any war between Sun and Liu, the best place to take refuge would be Guiyang City.

In fact, there have been some frictions and small-scale battles between Sun and Liu on the Jingzhou issue over the years...... It can't be regarded as a war, it can only be regarded as some conflicts, but the result is that as soon as the people in these friction areas heard that there was going to be a war here, they immediately ran to Guiyang with their families, and the people who came back after that were called pitiful. The war between Sun and Liu is for the land, but if there is land, there must be a population, and now that the population is gone, what is the significance of this land? Could it be that they can still go to Lu Ren to ask for these populations? Not to mention that Lu Ren is too lazy to bird them, even the people who escaped are too lazy to bird them!

So the next result is that Liu Bei and Sun Quan have wisely chosen to remain calm and restrained, not when they can really kill the other party with one blow, no one will easily make a move or provoke some trouble, and the Jingzhou region has maintained a relatively strange peaceful situation.

However, this kind of peaceful situation, Liu Bei will never dare to take it lightly, the soldiers who should be left and the generals who should be left behind are honestly left in Jingzhou, and Zhuge Liang is the representative of the generals who should be stayed. At the same time, it is precisely because Liu Bei left troops and generals in Jingzhou that the preparations for sending troops to Hanzhong have also been affected accordingly, and the delay of half a year before taking action is actually fast.

But no matter what, the battle for Hanzhong finally started. Liu Bei can be said to be the best and launched wave after wave of onslaught on Yangping Pass. And Xia Houyuan and Zhang He left by Lao Cao are not fuel-efficient lamps, and according to Shouxiongguan, they took advantage of the location to beat back the onslaught on Liu Bei's side again and again...... Well, these are not very different from the original history.

However, at this time, the great influence of a few key figures also manifested itself. In the original history, it was Fa Zheng who came up with the idea and asked Huang Zhong to cut Xia Houyuan. The current situation is that Huang Zhong is here in Lu Ren, and Liu Bei is missing a fierce general. But it is also because of Lu Ren, although Liu Bei has one less old Huang Zhong, he has one more phoenix Pang Tong. And if Pang Tong is holding back his mind to play conspiracy, Fa Zheng will have to lean to the side.

In short, Xia Houyuan and Zhang He fell for Pang Tong's plan, and retreated very embarrassed after losing the pass, and Liu Bei was also very reluctant to take Hanzhong and Yangping Pass, but because Liu Bei suffered relatively large losses in the early stage, he had to temporarily stop to rest and replenish. Liu Bei knew very well that Lao Cao was about to come over with Cao Wei's main force, and if he didn't hurry up and do a good job of resting and supplementing, then if he ran into Lao Cao, he would only suffer defeat.

At this time, the time had reached the autumn of the twenty-fourth year of Jian'an, and Liu Bei and Lao Cao formed a situation of fighting against the soldiers in the Yangpingguan area. At this point, Liu Beizhi used the word "drag" against Lao Cao, as in the original history, with the intention of dragging until Lao Cao's military strength was exhausted, and then evacuating from Hanzhong in a gloomy manner.

Stop, stop, the current Lao Cao is of course very depressed, but when his own situation has not been rotten to a certain extent, Lao Cao does not want to withdraw from the army easily. And war is often like this, many times whether the tide of war can turn around depends on whether the coach can hold on a little more.

————————————————————

In the military tent, the depressed old Cao was reading a book to relieve the depression in his heart. In fact, by this time, Lao Cao already felt that most of Hanzhong could not get it back. It's not that Lao Cao doesn't have the strength to fight Liu Bei anymore, but Lao Cao is a little worried about the situation in his back garden, so now it's a standard tiger ride.

But Lao Cao is not really unprepared at all. In fact, since earlier, Lao Cao has already begun to empty the population here in Hanzhong, in other words, to prepare to throw Liu Bei an empty city with no population at the last moment. The result of this is that although Liu Bei occupies Hanzhong, he has to mobilize the population to Hanzhong from other places, which can delay the growth of Liu Bei's strength in some aspects.

It's just that the thought of losing Hanzhong makes Lao Cao's heart still very unhappy, so he is just reading books very indiscriminately at this time, and he is not really reading seriously. Just flipping through the room like this, someone suddenly reported that there was an urgent military report, and when Lao Cao called the messenger into the big tent, and saw the blood stains on the messenger's body, Lao Cao's heart immediately tightened, and he asked urgently: "What happened?" ”

The messenger's body was injured and tired, and he couldn't hold it anymore at this moment, but he still bent himself up and reported to Lao Cao Yu: "Qi Wei Gong! The border of Liangzhou is urgent! ”

"Liangzhou border!?"

Old Cao Teng jumped up at once, rushed to the messenger and grabbed the messenger's collar, and asked, "Why is the military situation urgent?" Explain it to the old man! ”

Finally, someone who understood persuaded Lao Cao, and then poured a few sips of water on the messenger and let the messenger slow down, and then the messenger told Lao Cao in detail.

At that time, there were the so-called "Thirty-six Kingdoms of the Western Regions" in the Western Regions. Of course, to put it bluntly, they are just tribes with permanent residences in central cities. In the period of the Two Han Dynasty, there were also the establishment of the Western Regions Protectorate to be responsible for the size of these small countries, but by the end of the Han Dynasty and the Three Kingdoms period, the Western Regions Protectorate of the Han Dynasty had long since ceased to exist, and the 36 countries of the Western Regions also had some chaotic changes, some of which were stronger, and some of which perished.

However, these are not important, the important thing is that in Lao Cao's period, especially after Ma Chao and Han Sui were dealt with in the early years, the situation in Liangzhou was basically relatively stable, and Lao Cao also left some suitable people to manage the border of Liangzhou. And Lao Cao's reinforcement of Hanzhong this time, the stable situation in Liangzhou is also a guarantee for Lao Cao, after all, Lao Cao came from Chang'an.

But! Now the news brought back by this messenger is that Liangzhou has been attacked on a large scale, and the army attacking Liangzhou, according to the messenger's report, is actually the coalition army of the 36 countries in the Western Regions!?

If this just happens, Lao Cao may not be too shocked, after all, the thirty-six countries of the Western Regions have always been not good birds, once they feel that their wings are stiff and their confidence is enough, they will think of going to the Central Plains of China to get a handful, and in the history of the Han Dynasty, this kind of thing has happened several times. Lao Cao left troops and generals in Liangzhou, wasn't it also to deal with this kind of thing? Then, in Lao Cao's expectation, the soldiers and generals he left in Liangzhou had the strength to beat back the enemy troops who wanted to make trouble.

But the messenger's next words really shocked Lao Cao, that is, the Western Regions Alliance Army had actually broken through several towns, and more importantly, when they attacked the towns, the Western Regions Alliance Army, which had always been dominated by nomadic cavalry, actually moved out artillery when attacking the towns!?

Do you say that the rammed earth walls and thick wooden gates of that era could withstand the bombardment of artillery? What's more, due to the restrictions of the geographical environment and other aspects of the towns in the Western Regions, the quality of the city walls and gates is not very good! Although it is okay to block the general cavalry and infantry, but when it encounters artillery bombardment, the outcome can be imagined. So it didn't take long for the towns on the border of Liangzhou to lose several of them, and then according to the news brought back by the messenger, it seemed that these Western Regions coalition forces had the intention of marching to Chang'an.

There was a loud bang, but Lao Cao almost broke the table in a fit of rage, and then everyone heard Lao Cao's roar in a rage: "Artillery? Lu's machine crossbow (Lu Ren and Shirley's improved individual crossbow, the world called it Lu's crossbow or Yihao crossbow out of naming habits at that time)!? How could the thirty-six countries of the Western Regions have these things? It's okay for Lu's crossbow to arrive, but the old man has never been able to buy this thing from Lu Ren for so many years! Lu Ren child! What do you think!? If you sell this kind of thing to Liu Bei or Sun Quan, the old man won't say anything about you, but how can you sell these things to the people of the Western Regions? Didn't you yourself say that our rivalry is just a family dispute, but you must never let outsiders harm our big man!? ”

The people on the side immediately looked at each other, and some people reacted quickly, and immediately stepped forward to persuade Lao Cao that now was not the time to complain. According to the current situation, it doesn't matter if Hanzhong is thrown away, but if something goes wrong in Chang'an, Lao Cao will be cut off from the back road, and he won't even be able to return to the Central Plains if he doesn't make a good scene, so I hope Lao Cao can make a decision immediately.

And what else can Lao Cao say at this time? It's all burning eyebrows, and you still want to knock hard with Liu Bei? What's even worse is that there is still a long way to go from Hanzhong to Chang'an. Therefore, Lao Cao immediately ordered the whole army to evacuate, and ordered Xia Houyuan (there was no incident on Dingjun Mountain, so Xia Houyuan did not die) to lead the elite cavalry to Chang'an one step ahead to help Zhong Xuan stabilize the position on the Chang'an side first, and Lao Cao himself would lead the main army to return to Chang'an day and night.

Lao Cao's withdrawal, of course, was in line with Liu Bei's intentions, and Liu Bei didn't think about pursuing Lao Cao or anything, but he also sent troops to harass Lao Cao's rearguard appropriately, and even came back with some prisoners of war or something for interrogation, so he immediately learned the reason for Lao Cao's withdrawal. And this reason is also a bit unexpected on Liu Bei's side, and at the same time, he is also sensitive to the fact that the Western Regions Alliance Army will have such a movement, it should not be so simple......
