Eighteen years of Jian'an, August 18.

The summer heat has already swept through the Emperor, and the lush hills and woods on both sides have not brought half of the coolness to such weather.

The atmosphere of slaughter caused the birds and beasts in the surrounding mountains and forests to flee in all directions, and in the valley road, which was still spacious and flat, the two armies met in the scorching sun at noon, which was nothing more than ordinary.

There was no superfluous nonsense, and at the same time when they discovered the other party, Cao Hong and Liu Feng decisively gave the order to attack at the same time.

This is the first real collision between the army and the army since the Cao army entered Hanzhong, the fierce fighting broke the tranquility in the valley, and the bloody surprise attack attracted the covetousness of the mountain beasts, but such a fierce fighting scene is a fierce big worm, and they dare not rush in to eat like this.

Liu Feng's choice to take the initiative naturally has his reason, the summer in Shu is different from the Central Plains, in the sultry environment, it is difficult for outsiders to come in for the first time without being affected, and the Shu army has long been accustomed to this climate, and there will be no discomfort, this is the time of day.

And this belongs to the hilly area, the Shu army is best at mountain warfare, fighting in the field, even more advantageous than defending the city, Xixian is just a small city, not much stronger than the original Chuyang, it is better to give full play to the strengths of the Shu army, this is the geographical advantage.

As for the people, the local battle is already possessed, so the time and place are all on their side, and the difference in strength is not big, at this time, there is no problem for Liu Feng to choose to take the initiative.

And the fact is just as Liu Feng expected, after a short stalemate, most of the Cao army is not accustomed to the shortcomings of the climate in Shuzhong will be exposed, the humidity is much greater than the outside climate, the march on weekdays is not very obvious, at the moment into a fierce battle, but after a while, there will be breathing difficulties, no matter how powerful the elite, ten percent of the strength can only play six or seven percent, put on the battlefield, this can be directly converted into casualty ratio.

After tens of thousands of people fought fiercely in this valley for an hour, the disadvantages of the Cao army gradually became prominent, and the soldiers on the battlefield may not feel it, but as the main generals who control the overall situation, Cao Hong and Liu Feng can clearly perceive this change.

Cao Hong is a fierce general under Cao Cao, experienced in a hundred battles, at this moment to see that the momentum is not right, but he did not dare to immediately order Mingjin, the two sides are fighting fiercely, if you rush to Mingjin, it is likely that the defeat will directly change into a rout.

You can't even retreat, you can only keep shrinking the formation to stabilize your position.

Although Liu Feng had the upper hand, he was facing the elite of the Cao army after all, and Cao Hong was obviously not the kind of mediocre general who immediately panicked when he saw that the situation was not good, and this advantage failed to completely transform into a victory after all.

The sky is full of arrows and rain densely, like locusts in the slaughter period, there are people dying in battle at all times, such a fierce confrontation lasted until the evening, Cao Jun finally could not support it, began to rout, the loss of soldiers and horses has been more than three percent, to hold on to now, it is already Cao Hong's way of governing the army, for ordinary troops, I am afraid that when there is a disadvantage, it has already begun to rout.

Liu Feng judged the situation and saw that Cao's army had already shown signs of rout, so he did not give up, but waved his troops to press it, and pursued it until the sky was completely dark, and then Liu Feng collected his troops and returned to the city.

Cao Hong faced this situation, he could only be helpless, and after determining Liu Feng's retreat, he led the remnants of the army to retreat for twenty miles, and then ordered someone to collect the rout.

In this battle, Cao Hong was a little aggrieved, not lost to Liu Feng, but lost to this damn climate, the soldiers were not accustomed to the soil and water, and the troops had no advantage, and they could hold on until now, to be honest, it was already good.

However, the other party's generals fought really well, and after settling down, Cao Hong asked left and right: "Do you know who the guard of Naxi County is?" ”

"Look at the banner, when it is Liu Feng, it is the righteous son of the big-eared thief when he was in Jingzhou, after the Battle of Chibi, he once swept the land of the four counties of Jingnan with Liu Yi with 2,000 soldiers and horses." Cao Jun's intelligence collection of Liu Bei is still very detailed, including Liu Yi, the lord of Mocheng who took refuge with Liu Bei before the Battle of Chibi, and in Cao Jun's intelligence, he is also a core figure belonging to Liu Bei's group.

"Liu Feng?" Cao Hong was a little depressed when he heard this, although there was a reason for today's defeat, but he was a dignified general, who had dominated the world for decades, and now he was defeated in the hands of a junior, which made him feel angry.

Xixian has been prepared, only with their own hands of soldiers and horses, and defeated for a while, more than half, although not angry that they were defeated in the hands of a junior, but look at Liu Feng's arrangement, it is difficult to win more with less, Cao Hong can only find a place to rest for one night, early the next morning, count the soldiers, and bring 5,000 soldiers and horses when they came, but now there are only more than 2,000 people left, not to mention the siege, if Liu Feng leads the troops to fight again, Cao Hong has no confidence to fight against the other party.

And Xixian seems to have been prepared, this fast attack strategy is completely destroyed so far, but Cao Hong is not reconciled, Xixian can not be attacked, but since he is here, why not detour to the Fangling checkpoint and hit Fangling directly, even if he can't break through Fangling, he can also attack the enemy's grain road and help Cao Ren break through that checkpoint, at that time, after converging Cao Ren's army, it is not difficult to break Fangling again.

This kind of thought can't be stopped together, Cao Hong's personality is somewhat similar to Wei Yan, and he is also the kind who dares to take risks, after thinking about it in his heart for a while, he did not lead the soldiers and horses back the same way, but went straight to Fangling.

Obviously, Cao Hong didn't know how harsh Liu Yi was on intelligence requirements, within the scope of this battlefield, Liu Yi could be said to be all over the eyeliner, don't say that Fang Ling is now at war with Cao Jun, that is, Shangyong's side, within a radius of thirty miles, as long as there is a trace of Cao Jun, Shangyong will immediately enter a state of combat readiness, just like Liu Yi said before, do not seek merit, but seek no fault, the enemy wants to win him, can only come through the frontal battlefield, nothing else.

Cao Hong has not yet approached Fangling, and Liu Yi has already gotten the news.

"Sir, how could Cao Hong be here?" Meng Da looked at Liu Yi in amazement, not understanding why Cao Ren came here.

"It is estimated that Xixian County was frustrated, and I temporarily thought of taking Xixian County to bypass the rear of our army and surprise attack Fangling." Liu Yi thought about it and said, this result is not difficult to guess, as for the cutting off of the grain road, Fangling is less than ten miles away, and Cao Hong has no cavalry, and the idea of really fighting this is to suffer the enemy on the back and look for death.

"The last general will meet him!" Meng Da said with a smile, in the past two days, he has gradually seen the weakness of the Cao army, he is not suitable for water and soil, he is not good at fighting for a long time, and he is fighting in this place of Hanzhong, and the advantage occupied by the Shu army is too great.

"Don't worry, let's invite you into the urn." Liu Yi shook his head and said with a smile, after all, it takes too many troops to fight out of the city, even if Cao Hong is destroyed, the troops on Fangling's side will be insufficient.

"Please enter the urn?" Meng Da looked at Liu Yi blankly, what do you say? I haven't heard of it.

"Do as I say, transfer all the people I used before, take advantage of that Cao Hong is not here, make some things, and in addition, carry down the two broken crossbows on the city wall first." Liu Yi shook his head and smiled, he just felt that this word was appropriate, as for the origin of this sentence...... The ghost knows, so it's better to think it's your own original.

"Whoa!" Meng Da nodded, and didn't ask any more, although the broken army crossbow is powerful, but there are only two here, and the deterrent effect is far less than the shock of ten crossbow machines launched at the same time in Yangping Pass.

With the continuous improvement of Liu Yi these days, the scale of the entire Guancheng has also been built, the two city walls in front and back are separated by a mile, but the back is the valley mouth, and the city wall is sixty zhang, and now it has not completely dried up, Liu Yi will not want to be scary again, right?

Meng Da looked at Liu Yi and guessed in his heart what kind of invitation Liu Yi used to invite you into the urn?

Liu Yi didn't say much, as the current supreme leader of Hanzhong, some necessary mysteries are still needed.

Liu Yi wrote another letter to Fang Lingling, asking him to cooperate with him.

And a group of craftsmen are working day and night under the command of Liu Yi.

Cao Hong led the remnants of the army, spent three days to renovate, boost morale, but also from the countryside along the way, plundered some food to replenish, in order to avoid leaking the news, Cao Hong is to slaughter the three villages where he passed, so along the way, Liu Bei's soldiers and horses did not seem to find this infiltrated soldiers.

Three days later, Cao Hong took these soldiers who had regained their morale to the vicinity of Fangling and sent people to inquire about the news of Fangling.

"General, the four gates of the house are closed, only when transporting grain and grass, will half of the city gate be opened to send things to the pass in front, and the humble duty wants to blend in, but he was almost shot by the defenders, there is no official road to guide him, and no one is allowed to enter and leave the city gate before our army retreats." The soldier in charge of inquiring about the news came back and bowed to Cao Hong.

"Transporting grain and grass?" Cao Hong's eyes lit up, and he looked at the general and said, "Send someone to secretly investigate, how and when will the grain and grass be transported?" ”

Asking this, naturally I don't want to cut off the other party's grain road, between this level and the city, not even ten miles, I really go to intercept the grain, people can see it standing on the city wall, Cao Hong wants to try to see if he can pretend to be the Shu army, come to fish in troubled waters, first take down this damn level, as long as this level is taken, Cao Jun's tens of thousands of troops are put in, just a house mausoleum, how can it be stopped?

"Whoa!" The general agreed, took the order to leave, and secretly investigated how the Shu army transported supplies.

In this way, it lasted for another two days, and the scout found out the intelligence and came to report: "General, I have caught a Shu army and asked, the grain and grass will be delivered once every three days, and the gate will be opened directly at that time." ”

"Good!" Cao Hong was overjoyed when he heard this: "You will lead people to turn into the grain transport team tomorrow, and after entering the city, you can occupy the city gate, and I will lead the army to attack it and take this damn Guancheng!" ”

"Whoa!" When the general heard this, he also thought that this method was good, so he nodded and took the order......
