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

Liu Yi didn't know if his prayers had worked, or if he was really the legendary protagonist. In the next three days, Cao Hong just continued to expand his camp and did not mean to attack. It was 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 and stood on the mountain and looked like a long snake, stretching to an invisible place.

"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 a routine matter every day. He was more curious now that this city wall could really become as strong as Liu Yi said. After all, when the city wall was just built, he could poke a hole even if he stretched out his finger. After these three days, if it was mud, it wouldn't be broken with one touch, right?

"You will know it after a try." Liu Yi pointed to the city wall and signaled Meng Da to try it.

As for how to try, it is naturally a test in an attack manner.

Meng Da nodded and took a ring-headed knife from a soldier. In order to prevent Liu Yi from looking bad on his face, Meng Da did not use much strength to take a deep breath and slashed it on the female wall with a casual knife.

"Ding~"

With a crisp sound, the knife bounced back. Meng Da stared at the city wall that had only been split a little bit. Although he didn't use much effort, if he continued like this, the normal city wall should at least have a gap or something.

After handing the ring-headed knife back to the soldiers, Meng Da squatted down, touched the female wall carefully, and pushed it hard again. He could intuitively feel that the city wall was completely different from three days ago. He turned his head to look at Liu Yi and said in surprise: "Sir, you're so amazing!"

Even among Liu Bei's generals, I don't really know much about cement. It's not that I intentionally conceal it, but... Which general would have nothing to do to study the structure of the city wall and the subtle differences between soil?

"Then let's complete this level!" Liu Yi looked back at the military camp behind. Apart from this city wall, there was actually no difference between the two sides of the city wall. In other words, this looked like a place that was a heroic pass, but it was actually a wall. At that time, Liu Yi was not sure whether Cao's army would go to the end. In order to avoid Cao's army breaking the city and discovering the difference in the city after the Cao army then, he used this in turn to restrict them, so Liu Yi only built one city wall to facilitate the attack when he had to counterattack in the future.

Now that the defense is strong, there is nothing to be afraid of.

"The general is an expert in defending the city, so I won't interfere much." Liu Yi ordered people to remove the wooden boards and build the entire Guancheng framework, and ordered people to go to Fangling and asked Fangling County Magistrate to send someone to deliver the cement that he had ordered to transport here before. This thing is 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 up outside the city wall. Both sides would shoot each other from time to time. Although the level was not completely built, a city wall alone also had a certain range attribute. In addition, it was already condescending, the defenders would naturally not suffer any losses in such shooting. However, on the fifth day, the antlers and traps outside the city were basically cleared, and the siege battle was about to begin.

Liu Yi was still directing the craftsmen he hired to carry out construction in a hurry. The cement behind him kept transporting over, and the frame of the level was filled little by little, but he really never asked about military affairs.

Meng Da came down from the city wall and looked at Guancheng, which had already looked a little emotional in front of him.

By level, Liu Yi is undoubtedly the biggest one here. His reputation in the army and his reputation in the entire Hanzhong. Not to mention the hundreds of soldiers in a level, Liu Yi is more than enough to take over the troops of Shangyong, Fangling and Xixian counties.

But in addition to the extraordinary strength that Liu Yi showed when he asked to organize defense immediately and establish the level, he did not greedy for power after everything was done and handed over the things to experts. This is a very simple truth. But throughout history, how many people in power have truly achieved this?

"Sir, I am such a strange man!" Meng Da sighed sincerely at Liu Yi.

"Ah?" Liu Yi turned around and looked at Meng Da in confusion: "What did Zidu say?"

Meng Da shook his head and said, "Sir, the main force of Cao's army has arrived. I wonder how to deal with it next?"

"How to deal with it, how to deal with it. There are only a few tricks to defend the city. The general still needs me to teach me?" Liu Yi looked at Meng Da with a funny look and said, "We have sufficient troops. If we are in a tight position, we can send troops from Fangling at any time. If we feel it is difficult, just light a wolf smoke. Fangling County Captain will immediately send troops to help."

"The last general is saying, sir, do you have a plan to retreat to the enemy?" Meng Da said with a wry smile. Judging from the current situation, it is not easy for Cao's army to attack as long as they defend here. However, since they have achieved this, Meng Da naturally wants to go further. If he can retreat to Cao's army, then this contribution will be great.

"Not yet, let's waste it first." Liu Yi shook his head. The Cao army has tens of thousands, plus Fang Ling's defenders, but only one-tenth of them. It's good to use this level to block the opponent's path. Do you still want to retreat? Do you really think that Cao Ren and Cao Hong are rookies and let you bully them? Why don't you go to heaven?

Meng Da was not surprised when he heard this. Naturally, the strategy of repelling the enemy was not so easy to think about. He asked this just to confirm Liu Yi's attitude. As expected, there was no intention to intervene, which made Meng Da breathe a little.

He is a capable person, and he is not bad at all. Generally, a capable person does not want to have a boss who doesn't know anything but commands his own command. Now it seems that he is very lucky to meet a superior who is not very responsible but can manage the logistics in an orderly manner, and has his own persistent superior at critical moments. It is very comfortable to do things with such a person.

"Cao's army has not been fully arrived yet. I wanted to see him attack his camp while the opponent's army had not been integrated." 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? Not Wei Yan pretended to be?

"Defend the city, do whatever you want, but without my order, you must not leave the city to fight without authorization!" Frowning, Liu Yi said directly in an orderly tone, too lazy to explain anything.

"Here! Then I'll go to inspect the camp." Meng Da bowed to Liu Yi after hearing this, without any suggestion of being rejected. After greeting Liu Yi with a smile, hello and left.

Liu Yi glanced at the dark-skinned back, shook his head, and continued to direct the civilians to step up the city.

After a while, Liu Yi suddenly turned his head and looked towards the direction of the city wall. He realized that Meng Da was here to make up his own words.

Just ask?

After understanding this, Liu Yi shook his head with some amusement. Sure enough, there are pits everywhere in this life. God knows which one will dig the pit in front for you.

The city of Guan was almost built, and the next step was to wait for the cement to cool down. Even if the city was built, the main force led by Cao Ren finally met with Cao Hong. Cao Hong originally wanted to discuss with Cao Ren how to break the pass, but as soon as he met, he was scolded by Cao Ren.

"Zi Lian, you are also a soldier. Why are you building a camp like this? Are you going to ask me soldiers of the three armies to be buried with you?" As soon as we met, Cao Hong had not spoken, Cao Ren had already interrupted him directly.

"What does this mean by filial piety?" Cao Hong was immediately dissatisfied when he heard this. They were all from the Cao family. Is it necessary to be so fierce?

"What's the point?" Cao Ren pointed to the military camp and said, "This military camp has been deployed for thirty miles, and the head and tail cannot be matched. It is difficult to issue military orders quickly. If the enemy takes this opportunity to set off a fire, your thirty miles joint camp will probably be burned in an instant!"

this……

Cao Hong was a little stunned when he heard this. He had not considered these things before. Now that Cao Ren pointed it out, he suddenly realized that it was not. It was really unreasonable to arrange troops in such a formation. He then smiled bitterly: "But this mountain road is so narrow. How do you ask me to set up a village?"

Cao Ren shook his head and said, "Retreat ten miles first, don't let the enemy generals see the reality of our army. Since the road here is not open, I will try to break through this pass here. You will take a group of troops to seize Naxi County first."

The original plan was to occupy Fangling and Xixian first, and then defeat Shangyong with a threat, at least it would be fine to take Shangyong down.

Although the level in front of the road to attack Fangling is blocked, Xi County does not have such a level. As long as you take Xi County and send troops to Fangling based on Xi County, you can directly bypass this level and directly attack Fangling.

But that happens, it takes a lot of time. Will Shangyong reinforcements be supported? There are too many variables, but it is better than the long snake formation formed by Cao Hong's thirty-mile military camp? If the army set up a long snake formation, it can still connect to each other from the head to tail and take care of each other, but if the military camp is arranged like this, the long snake will become a dead snake.

Cao Hong was no longer resentful at this moment. Who could tell me the right thing? He could only agree to Cao Ren, and went to order a group of troops and left the camp. On the same day, he led his army out of the camp and headed straight to Xi County.

"Retreat the troops?" Standing on the city wall, Meng Da paid attention to Cao's movements and frowned slightly. If he retreated, it wouldn't look like it?

A flash of inspiration flashed in my mind, my face changed, and I quickly turned around and went downstairs to find Liu Yi who was taking people to make some military supplies.

"What's wrong with Zidu?" Liu Yi looked at Meng Da and asked.

"Sir, hurry up, Xi County is in trouble!" Meng Da took a breath and said, "Cao's army divided a group of troops and headed north, and I'm afraid it would be necessary to attack Xi County."

"Oh, I got it, keep defending the city!"
