Cao Hong was obviously frightened by the paper tiger in front of him, and he came to investigate every day as usual, but rarely did it.

Liu Yi didn't know if his prayers had an effect, or if he was really the legendary protagonist, Cao Hong in the next three days, just continued to expand the camp, and there was no intention of attacking, just because this section of the road was not spacious, and there was not enough space for Cao Hong to build a military camp, so Cao Hong's military camp was long, standing on the mountain and looking at it, it was like a long snake, and it stretched until it couldn't be seen.

"Sir, it's been three days, this city wall ......" Meng Da stood beside Liu Yi and looked at the Cao army camp in the distance, this was already a daily routine, and he was now more curious about how this city wall could really become as strong as Liu Yi said? After all, when this city wall was just built, you could poke a hole with a finger, and once the three days passed, if it was mud, it wouldn't break when you touched it, right?

"Try it and you'll find out." Liu Yi pointed to the city wall and motioned for Meng Da to try.

As for how to try, it is natural to try it in the form of an attack.

Meng Da nodded, took a ring head knife from the hand of a soldier, in order to avoid Liu Yi's face not looking good, Meng Da did not use too much strength, took a deep breath, and slashed at the female wall with a knife.

"Ding~"

With a crisp sound, the knife was bounced back, and Meng Da looked at the city wall that was only a little bit split, although he didn't use too much force, but with such a knife, the normal city wall should at least have a gap or something.

Handing the ring head knife back to the soldiers, Meng Da squatted down, carefully touched the female wall, and pushed it again, he could intuitively feel that the city wall was completely different from three days ago, turned his head to look at Liu Yi and said in surprise: "Sir, God!" ”

Cement, even among the generals under Liu Bei, don't really know much, not intentionally concealing it, but ...... What general would have no trouble studying what the structure of the walls looked like, the subtle differences between dirt and dirt?

"Then complete this level!" Liu Yi glanced back at the military camp in the rear, except for this city wall, there is actually no difference between the two sides of the city wall, in other words, this looks like a place of Xiongguan, in fact, it is a wall, at that time Liu Yi was not sure whether Cao Jun would be reckless to the end, in order to avoid Cao Jun from finding the difference in the city after breaking through the city at that time, and restricting them by this turn, so Liu Yi only built a city wall, so that it was convenient to attack when he wanted to counterattack in the future.

Now that the defense is solid, there is nothing to fear.

"The general is an expert in defending the city, so I won't interfere much." Liu Yi ordered someone to remove the wooden planks and build the framework of the entire Guancheng, and on the other hand, he ordered someone to go to Fangling, and asked the Fangling County Commander to send someone to send the cement that he had ordered to transport here, this thing, that is a strategic material.

In the next few days, Cao Ren's army arrived one after another, and began to carry out some tentative attacks, clearing the antlers and traps set outside the city wall before, and the two sides would shoot at each other from time to time, although the level was not completely built, but a single city wall also had a certain range attribute, plus it was already condescending, such a confrontation, the defenders would naturally not suffer, but on the fifth day, those antlers and traps outside the city were basically cleared, and then, the siege battle was about to begin.

Liu Yi was still directing the craftsmen he hired to carry out the construction in full swing, the cement in the rear kept coming over, and the frame of the checkpoint was filled in little by little, and he really didn't ask a word about military affairs.

Meng Da came down from the city wall, looked at the city in front of him, which already had a bit of a city appearance, and couldn't help but feel a little emotional.

According to the level, here, Liu Yi is undoubtedly the biggest one, the prestige in the army and even the prestige of the entire Hanzhong, Liu Yi not to mention mastering the hundreds of soldiers in a checkpoint, that is, if he wants to take over the soldiers and horses of the three counties of Shangyong, Fangling, and Xixian, it is more than enough.

But in addition to Liu Yi's extraordinary strength when he asked to organize defense immediately and set up checkpoints at the beginning, after everything was done, he was not greedy for power at all, and handed things over to the insiders to do, which is a very simple truth, but throughout the ages, how many people in power have been able to really do this?

"Sir, what a strange person!" Finding Liu Yi, Meng Da said with heartfelt emotion to Liu Yi.

"Huh?" Liu Yi turned around and looked at Meng Da suspiciously: "What did Zidu say?" ”

Meng Da shook his head and said, "Sir, the main force of the Cao army has arrived, I don't know how to deal with it next?" ”

"How to deal with it, how to deal with it, there are so many tricks to defend the city, and the general still needs me to teach you?" Liu Yi looked at Meng Da with a smile and said: "We have sufficient troops, if we are tight here, we can transfer troops from Fangling at any time, if you feel tired, you only need to light the wolf smoke, and the county lieutenant of Fangling will immediately send troops to help." ”

"The last general said, does the gentleman have a plan to retreat from the enemy?" Meng Da said with a wry smile, if you defend the city, judging from the current situation, as long as you hold here, it will not be easy for the Cao army to attack it, but since this step has been achieved, Meng Da naturally wants to go further, if you can retreat from the Cao army, then this credit is not small.

"Not for the time being, consume first." Liu Yi shook his head, this Cao army has tens of thousands of people, plus the defenders of Fangling, it is only one-tenth of the people, and now it is not bad to use this level to block the other party's road, do you still want to retreat from the enemy? Really when Cao Ren and Cao Hong are rookies, let you bully them? Why don't you go to heaven?

When Meng Da heard this, he was not surprised, the strategy of retreating from the enemy was naturally not so easy to think, he asked this, just to confirm Liu Yi's attitude, and sure enough, he had no intention of interfering, which made Meng Da breathe a sigh of relief.

He is a capable person, and the ability is not bad, generally capable people, do not want to have a boss who does not understand anything and commands himself, now it seems that he is very lucky, meet a person who is not very in charge, but can take care of the logistics in an orderly manner, and at the critical moment has his own insistence on the superior, with this kind of person to do things, it is very comfortable.

"Cao's army has not yet fully arrived, and the last general originally wanted to take advantage of the fact that the opponent's army has not been integrated to attack his camp." Meng Da explained with a smile.

When Liu Yi heard this, he looked up at Meng Da, a little surprised, is this really Meng Da? Didn't Wei Yan pretend?

"Defend the city, do whatever you want, but without my order, you must not go out of the city to meet the battle!" Frowning, Liu Yi said directly in a commanding tone, and didn't bother to explain anything.

"Whoa! Then the general went to inspect the camp. Hearing this, Meng Da bowed to Liu Yi, without the slightest grievance of being rejected for his suggestion, and after greeting Liu Yi with a smile, he turned around and left.

Liu Yi glanced at Meng Da's back, shook his head, and continued to command the people to step up the erection of this city.

After a long while, Liu Yi suddenly turned his head and looked in the direction of the city wall, he could be considered to have reacted, this Meng Da is here to set his own words.

Just ask, isn't it over?

After thinking about this, Liu Yi shook his head with some amusement, sure enough, this life is full of pits, God knows which pit in front of you will be dug for you.

The city is almost built, and the next thing is to wait for the cement to cool, even if the city is built, at the same time, the main force led by Cao Ren finally converged with Cao Hong, Cao Hong wanted to discuss with Cao Ren how to break the pass, but just after meeting, he was scolded by Cao Ren for splitting his head and covering his face.

"Zilian, you are also a person who knows the soldiers, why are you so camped this time, do you want to ask the soldiers of my three armies to be buried with you?" Just met, before Cao Hong could speak, Cao Ren had already directly interrupted him.

"Zixiao, what do you mean?" When Cao Hong heard this, he was immediately a little unhappy, they are all members of the Cao family, is it necessary to be so fierce?

"What do you mean?" Cao Ren pointed to the military camp and said: "This military camp is fully thirty miles long, and the end cannot be corresponding, and it is difficult to issue military orders quickly. ”

This......

When Cao Hong heard this, he was a little dumbfounded, he hadn't considered these before, but now he was pointed out by Cao Ren, and suddenly realized, but no, it is really unreasonable to arrange troops like this, and then said with a wry smile: "But this mountain road is so narrow, how do you tell me to set up a village?" ”

Cao Ren shook his head and said: "Retreat ten miles first, don't let the enemy general see the reality of our army, since the road here is not passable, then I will try to break through this pass here, and you will take a group of men and horses to capture Naxi County first." ”

The original plan was to occupy the two cities of Fangling and Xixian first, and then attack Shangyong with coercion, at least it was no problem to take Shangyong.

Now although the road to attack Fangling is blocked in front of this checkpoint, but Xixian County does not have this kind of checkpoint, as long as Xixian County is taken, and then based on Xixian County, troops are sent to Fangling, you can directly bypass this checkpoint and directly capture Fangling.

It's just that in that case, it will take a lot of time, whether there will be reinforcements on the Shangyong side, there are too many variables, but it is better than the long snake formation set up by Cao Hong's thirty-mile military camp, right? If the army is set up in a long snake formation, it can still be connected end to end and take care of each other, but if the military camp is placed in such a way, the long snake will become a dead snake.

Cao Hong has no resentment at the moment, who is right? I could only promise to Cao Ren, went to order a group of men and horses, withdrew from the camp, and led the army to withdraw from the camp on the same day, and led the army straight to Xixian.

"Withdrawn?" Standing on the city wall, Meng Da paid attention to Cao Jun's movements, frowning slightly, if he retreated, it wouldn't look like it?

A flash of inspiration flashed in his mind, his face changed, and he hurriedly turned around and went down to the city to find Liu Yi, who was leading people to make some military supplies.

"What's the matter with Zidu?" Liu Yi had already looked at Meng Da and asked.

"Sir, quick, Xixian is in trouble!" Meng Da took a breath before he said: "The Cao army sent a group of men and horses to the north, I'm afraid it is going to attack Xixian." ”

"Oh, got it, let's keep defending the city!"
