With Cao Zhen's order issued, the Wei army camp suddenly fell into a busy situation.

He led the soldiers to prepare dry firewood, and arranged fire and flammable materials in the various camps.

Shi Bao led his soldiers and horses to make rockets.

Cao Zhen and Chen Tai traveled to and from various mountains and forests, looking for suitable places to hide soldiers.

Three days flew by.

On the evening of the third day, Ma Chao led his troops to Lund City.

"The last general has seen Your Majesty!"

"Hurry up, please!" Liu Chan helped Ma Chao up, and when he saw Ma Chao, Ma Dai, and Lin Yuan, the three generals had a smile on their faces, and they were not discouraged, they were overjoyed in their hearts, and said with a smile: "Aiqing rushed here to join me, could it be that he has already succeeded?" ”

Ma Chao arched his hand and said: "The last general was ordered to make a detour to the rear of the Wei army, and destroyed nearly 150,000 stones of grain and grass for the Wei army. It is estimated that the grain and grass of the Wei army in Longshan will be eaten in two days, and Chang'an, at least within ten days, will not be able to transport the grain and grass. ”

"Huh?" Listening to Ma Chao's words, Liu Chan frowned and said, "No, if the Wei army should have eaten all the grain and grass in these two days, it should retreat." Why is there no sign of retreat now? Let's go back first, Aiqing, you can talk to me about the situation and details of this trip. ”

When everyone returned to the city, Ma Chao explained the trip to Liu Chan in detail.

"After the general received His Majesty's order, he first went to Gaoping, destroyed a batch of grain and grass that the Wei army transported to the front line, and after succeeding, he hid his traces and rushed to Linjing, waited for three days, and finally waited for a batch of 100,000 stone of grain and grass to be transported to Longshan, and successfully burned it.

At this time, Xiahou Rong led the army to Linjing, he spent four days in Linjing to raise more than 30,000 stone grain and grass, and rushed to support Hu Zun to transport grain and grass to Longshan, the last general took the strategy of exhausting the army, and it took four days to make the Wei army exhausted......"

After Ma Chao finished speaking, Liu Chan muttered: "When you destroyed the Wei army's 100,000 stone grain and grass, you captured the Wei general, according to what he said, the grain and grass of the Wei army in Longshan is only enough to eat for less than half a month, and it should be twelve days to the specifics." ”

Ma Chao nodded and said: "Yes, and this still refers to the grain and grass of 20,000 people, because the Linjing guard didn't know Meixian at that time, and Huating sent 20,000 reinforcements over."

Xiahou Rong and Hu Zun successively brought 13,000 soldiers and horses out, and Longshan had 27,000 guards, so the consumption of grain and grass was faster, less than 27,000 people for 12 days. ”

Liu Chan continued: "After this, it took Xiahou Rong four days to raise grain and grass in Linjing, and it took you another four days to deal with Xiahou Rong, and it took another three days to arrive here, a total of eleven days.

The surplus grain of the Wei army was only enough for the 20,000 troops for 123 days, and if they were frugal, the 27,000 soldiers and horses should only be able to last for about 134 days. In this way, the defenders of Longshan will run out of food within two days at most, but why don't they retreat?

It takes five days to gather troops and horses, and then withdraw to Linjing, and the Wei army only has two or three days of food and grass left, but does not retreat, isn't it self-defeating? Could it be that they have some conspiracy waiting for us? ”

Cao Zhen decided to fight against the water and use fire to deal with the Han army, but he didn't expect Liu Chan to deduce something strange from the grain and grass.

You only have two days of food left, and it takes five days to go to Linjing, but you don't retreat, except for self-defeat, only a conspiracy can be explained. This is the deadliest time difference.

As for how much food and grass the Wei army has, and how many more days it can last, Liu Chan feels that it is impossible, because on this day, it is still more than that, if the Wei army continues to reduce the food of the soldiers, then the army will be in chaos. But now the Wei army is not in chaos, which shows that Liu Chan's calculation is right.

Guan Yu said with a smile: "Your Majesty doesn't have to worry too much, since Meng Qi has burned nearly 150,000 stones of grain and grass for the Wei army, the defenders of Longshan have fallen into a situation where there is no food available, no matter what conspiracy he has, it is a dead end." ”

Zhuge Liang shook his head and said, "Yun Chang can't be careless, the more times like this, the more careful you must be." ”

Liu Chan looked at Zhuge Liang: "What does Da Sima think Wei Jun is fighting in mind?" ”

Zhuge Liang said: "The Wei army ran out of food but did not retreat, it is obvious that they are planning to break the kettle and fight against the water. It's just that his specific strategy, Weichen doesn't know yet, so he can only act at the opportunity, but our army should be extremely careful. ”

"Hmm!" Liu Chan nodded and said, "At this time, we should be more careful and pass on the order." In the past few days, the various camps have given me a spirit, and we must take strict precautions and not relax in the slightest. ”

The generals gave their hands to the order: "No! ”

On the other side, Cao Zhen was very depressed at the moment.

After Ma Chao defeated Xiahou Rong a few days ago, he did not kill his soldiers, but left some grain and grass for them to go back, and after three days, these soldiers returned to Longshan.

More than 13,000 people did not die and returned, if it was usual, Cao Cao should be very happy, because this 13,000 people are not a small number.

But now Cao Zhen can't be happy.

Because when Ma Chao left, he didn't give these people much grain and grass, and when they were on the road, the grain and grass were eaten by them, and these people came back hungry, and when they returned to Longshan, they were all hungry.

But here in Longshan, there is no surplus grain and grass now.

These people are coming back at this juncture, and it's very troublesome.

Chen Tai said with a sad face: "More than 10,000 soldiers are shouting hungry now, but our army can't come up with excess grain and grass now, how can this be good." ”

Cao Zhen sighed and said to the generals: "Let them eat grass roots and bark, I can't get a pound of grain now." Xiahou Rong, these soldiers are under your control for the time being, and tomorrow you will pretend to withdraw your troops and take them into action. ”

"No!" Xiahou Rong gave up his hand.

Cao Zhen looked at the generals and said: "Now that we are ready, according to the scout's report, Ma Chao has joined Liu Chan, and we can start the operation early tomorrow morning."

Tonight, Chen Tai and I, Shi Bao and I led 10,000 soldiers and horses to ambush in the mountains and forests. Tomorrow evening, when the southeast wind is at its strongest, let's go down the mountain and set fires.

Xiahou Rong, take the move, but when the two of you saw the fire, they immediately led their troops to kill back. ”

Longshan is a mountainous area, and at night, the southeast wind is the most violent, and if the Wei army succeeds in setting fire, its fire is enough to sweep the entire Longshan.

"No!" The generals will take the command.

That night, Cao Zhen and other generals led their soldiers and horses to hide in the mountains and forests.

As soon as it was dawn the next day, Xiahou Rong organized the retreat of his soldiers and horses.

Due to the arrangement in advance, by the third pole of the day, all the soldiers and horses withdrew from Longshan, and under the leadership of Xiahou Rong and Zhaozhao, they went to the east.

On Liu Chan's side, at noon, he also received the news of the retreat of the Wei army.

"Your Majesty, General Zhao Yun has sent news that the Wei army has all retreated, and he sent me to ask for instructions on whether to lead the troops to pursue or settle in the Wei army camp."

"Your Majesty, there is news from General Lin Xiao that the Wei army has retreated, and the camp is empty, so I have been sent to ask for instructions on whether to lead the troops to pursue."

"Your Majesty, there is news from General Wei Yan that the Wei army has retreated, is it ......?"

"Your Majesty's ......"

The generals who were on the front line all sent people one after another to inform Liu Chan that the Wei army had retreated.

Zhang Fei smiled when he heard this: "It seems that we misestimated, the Wei army has a lot of grain and grass, so we retreated today, and there is no conspiracy." Your Majesty, what are you waiting for now? Quickly send troops to pursue, hit Chang'an in one go, and destroy the fake emperor of the pseudo-Wei! ”

Liu Chan glanced at Zhuge Liang, only to see that Zhuge Liang also looked towards him, with a little thought in his eyes, Liu Chan asked, "I don't know what advice Da Sima has?" ”

Zhuge Liang said: "Now that the Wei army has retreated, there is no need to be busy pursuing, the Wei army has lost Longshan, and our army is victorious." The first to occupy the Wei army camp is making plans, but in order to avoid the Wei army from cheating, go to the Wei army camp to check first. ”

Liu Chan shook his head when he heard this, got up and said, "I'm going to go for a trip." ”

Guan Yu arched his hand and said: "Your Majesty doesn't have to go in person, the last general will go for Your Majesty." ”

Liu Chan shook his head and said, "I always feel that something is not quite right, so let's go in person, and the generals will go with me." ”

"No!"

After a short time, everyone was ready, rode fast horses, and in just an hour, they rushed to a camp of the Wei army.

This area was in charge of Zhao Yun, but without Liu Chan's order, the Han army did not settle in the Wei army camp, and Zhao Yun came with Liu Chan.

Zhao Yun looked at the camp in front of him and said to Liu Chan: "This is the camp that General Ling attacked at the beginning, General Ling died in battle not far from outside this camp, and this camp is the largest one in this area. ”

"Hey!" Liu Chan sighed and said, "Let's go in and have a look!" ”

Everyone entered the camp, and Liu Chan looked around the camp.

The Wei army in the camp had retreated, and tents, wood, and thrown everywhere were disorganized.

"Looking at this situation, the Wei army is ready to retreat." Guan Yu stroked his beard and said: "Your Majesty, you see, this arrow tower and the like have been destroyed, and the Wei army doesn't want to leave it to us." In this way, it seems that the Wei army has indeed run out of food and retreated, and we have misestimated the amount of grain and grass they have. ”

"It always felt like something wasn't quite right." Liu Chan shook his head, looked at Zhuge Liang, and Fa Zheng and the others asked, "What do you think?" ”

Fa Zheng smacked his lips and said, "There seems to be a lot of wooden tents left behind." Since the food and grass were sufficient for the retreat, and the preparations were sufficient, the tent should be able to be taken away, so that not so much was left on the ground, and it was destroyed. Since there is a ruined time, why not organize it and take it away?

And the number of arrow towers in this camp is not right, the scale of this camp is not large, how can there be so many arrow towers, there are a bit abnormal. And when leaving, why did you destroy the arrow tower and get wood everywhere? Even if we don't destroy the arrow tower, it won't help us to stay, so why bother. ”

Hearing this, Liu Chan squatted down and carefully observed the horizontal and vertical wood on the ground. These timbers were all facilities in the Wei military camp, such as the arrow tower, such as the trident for erecting the brazier.
