When Liu Yi built the two capitals, it was not just as simple as building two capitals, Luoyang and Hedong, Hanoi is only separated by a water, in winter, the river is frozen, Hedong, Hanoi soldiers and horses can directly cross the river on the ice, in order to avoid unnecessary wars, Liu Yi based on Mengjin, built several passes, in order to consolidate the defense line in the north of Luoyang, and at the same time, the revolving gate pass, Xuanyuan Pass was also strengthened.

Now, with the mobilization of troops and horses on the Han side, the Wei Dynasty also began to garrison troops in Hedong and Hanoi, and when Liu Yi arrived in Luoyang, the Wei Dynasty had already built a defensive line in Hedong and Hanoi.

"Looks like I still can't hide it." At the Mengjin ferry, Liu Yi looked at the enemy building built on the opposite bank and handed the telescope to Deng Aidao beside him.

"The dispatch of hundreds of thousands of troops, it is impossible to say that the Wei Dynasty is unaware." Wei Yan smiled bitterly.

"Cao Rui just died, but the speed of the Wei Dynasty's soldiers and horses dispatch has not been affected in the slightest." Liu Yi sighed and said, "It seems that it is impossible to make an off-board move." ”

"The puppet emperor of the Wei Dynasty is only an eighteen-year-old child, what is his ability, it must be the minister of the court and the central government in power." Wei Yan looked at Liu Yi and asked, "Can you use this to stir up internal contradictions in the Wei Dynasty?" ”

"Who is in charge within Cao Wei is actually indistinguishable to us." Liu Yi shook his head and said: "It doesn't help to use this to provoke, even if Cao Fang is not sensible, the supporters around him also understand the importance of this battle, and I am now more concerned about who the two auxiliary ministers are to fight against us." ”

Cao Shuang and Sima Yi, if Liu Yi is allowed to choose, he will definitely choose Cao Shuang, but it is impossible for Cao Wei to follow Liu Yi's wishes.

"There's no news yet." Wei Yan shook his head, he didn't even know who his opponent was until now.

"Let's try to attack first." Liu Yi thought about it and said, his original plan was to fight the war in Hanoi, as long as there is a foothold in Hanoi, this battle will start, and the initiative will be in his own hands, but he didn't expect Cao Wei's reaction to be faster than Liu Yi imagined, even if the Han side did not delay, but Cao Wei's side has already made arrangements.

In this way, the battle will be difficult to fight.

"Whoa!" Wei Yan nodded, looked at the enemy tower built on the opposite bank, and thought about how to attack.

"Ma Qiu!" Liu Yi looked behind him, nodded to a general, and said, "You take a team of men and horses to patrol up along the river to avoid the opponent's water attack." ”

Ma Qiu is the son of Ma Chao, inherited Ma Chao's title, and is similar to Ma Chao in appearance, but he is a little less domineering than Ma Chao and a little more elegant, and he can be regarded as a talent in the second generation of the Han Dynasty.

"Governor, there's no need, right?" Wei Yan looked at Liu Yi and said with a smile: "Then Cao Wei can still cut off this big river?" ”

"Who says you can't?" Liu Yi said with a smile: "If I am the commander of the Wei army, I know that the Han is going to attack, and I will use the winter to dig ice and build a dam in advance, so that even if the river thaws, the water level in Luoyang will not drop significantly, and when the gate is opened to release the water, it will be a shock!" ”

"How much trouble is this?" Wei Yan was a little stunned when he heard it.

"Sometimes a stupid solution is more effective than a clever one, and you have to put yourself in their shoes." Liu Yi smiled, then looked at Ma Qiu and said: "Remember, if there is no abnormality, fine, but if there is an abnormality, remember to startle the snake, come back and report it to me, I am free to care." ”

"Whoa!" Ma Qiu bowed down to receive the order, and led a team of men and horses to turn around and leave.

This section of the Yellow River is hundreds of miles, and Liu Yi can't take care of every place, so he can only investigate it now.

"The soldiers and horses are in the north of the mountain, don't move lightly, at present, we are now figuring out who controls the soldiers and horses in Hedong and Hanoi, be fast!" After arranging for Ma Qiu to inspect the Yellow River, Liu Yi said to Wei Yan.

"Whoa!" Wei Yan agreed and took the order.

This time Liu Yi sent troops to Luoyang, 150,000 soldiers and horses gathered in the north of Beibi Mountain, the entire north of the river bank as far as the eye can see, are endless military camps, a large number of soldiers to and fro to inspect or train, the original barren land, but now shrouded by the atmosphere of war.

On the opposite shore, there are also enemy towers and arrow towers, and after the Han and Wei families were calm for several years, the war was about to break out again.

Early the next morning, Wei Yan led a fleet of ships to look for provocations, relying on the advantage of the range of the strong crossbow to shoot arrows at the enemy tower of the Wei army from afar.

But then then by the other party's catapult to force back, the most terrible on the river bank is the catapult, that a stone bomb accidentally fell on the boat is a hole, now just to the end of the month, although this river is thawed, but it is cold and biting, if the boat really capsizes, even if a boatload of people is rescued, there are definitely not many who can survive.

After being tried several times like this, Wei Yan could only collect his troops and return to the camp to report to Liu Yi.

"The catapults of the Wei army seem to be a lot more powerful, and they seem to be everywhere, no matter where our fleet goes, there are at least a dozen catapults attacking us." Wei Yan looked at Liu Yi and said with a wry smile.

"The defense is so strong?" Liu Yi was stunned, and then thought of something: "When was the defense line in Hedong and Hanoi built?" ”

"This ......" Wei Yan thought about it for a while: "The last general has been in Chang'an for the past few years, and I don't know much about this, but I heard from Tanzhi that as early as the third year of Xingyuan, the Wei army began to build fortifications in this area, and there were also passes everywhere. ”

Liu Yi has been active in the Western Regions all these years, and he doesn't know much about the military here, and although there are many disputes between the Wei Dynasty and the Han Dynasty, most of them have conflicts in the areas of Yunzhou and Nanyang.

"In other words, Cao Wei, the defense line in this area, has been in business for eight years?" Liu Yi looked at Wei Yan.

"When it is." Wei Yan nodded.

Liu Yi took Wei Yan and came to the river again, looked at the river carefully, and then took a telescope to look at the Wei army's defense line on the opposite bank.

"Withdraw!" Liu Yi's face changed slightly, and he immediately said: "Inform Deng Ai and Jiang Wei to organize the soldiers and horses to retreat to the Beibi Mountain Heights." ”

"Why is that?" Wei Yan was puzzled.

"Obey the order, remember, don't pay attention to the camp, only move the grain and grass to the mountain, and you will continue to patrol the river with a group of men and horses, there must be no mistake!" Liu Yi said with a serious face.

"Whoa!" Seeing Liu Yi's serious face, Wei Yan hurriedly agreed and went to pass the order.

Liu Yi returned to the tent, carefully studied the sand table again, and after making some measurements with a measuring rope, he quickly came out of the camp and came to the river with measuring instruments to measure the water level.

Grass!

After Liu Yi stood up, he looked at Wei Ying on the other bank, and wanted to compare his middle finger, now he can be sure that this must be Sima Yi's old silver coin in the layout, the water level of the Yellow River has dropped by at least one foot compared to when Liu Yi built Luoyang, although he doesn't know where the other party is storing water, but it is estimated that the water will be released quickly.

But what really chilled Liu Yi was that the other party had predicted this battle as early as eight years ago, and began to prepare at that time, once this water was sent down, if there was no preparation here, the north of Beibi Mountain would become a Ze country, if he didn't notice it, I am afraid that the 150,000 army would be directly served by the other party!

Luckily, I have enough mechanics!

But since you have seen through it, why not make a plan? It's just that no one knows when the other party is going to do it, which is a problem, so we can only use this method.

In the next few days, Liu Yi secretly transferred his soldiers and horses to Beibi Mountain, and at the same time left a group of men and horses in the camp.

"What's the most normal thing to look like?" Liu Yi thought about this problem, while secretly transferring the army to the high ground, the military camp did not let the other party see the flaws, but hundreds of thousands of troops, how can they not be seen flaws, only rely on the men and horses in the camp, with the straw man, the other party may not notice it in a short time, but after a long time, the problem will be discovered.

Liu Yi wrote and drew on the paper, and found that if he only relied on 5,000 men and horses, he would not be able to make a scene of 150,000 troops anyway, after all, people are not stupid, a large number of straw men stand there motionless, even if there is no telescope, you can find out that something is wrong, right?

If it is oneself, if the other party inserts more flags in the army or the number of flags is not equal, you can detect it at a glance.

It's not how powerful it is, but the feeling of leading the troops for many years, the flag and the number of people are not equal, for characters like them who are used to seeing thousands of troops, there will be an uncomfortable feeling in their hearts, which is a kind of obsessive-compulsive disorder, once this feeling appears, there must be a problem.

Liu Yi didn't know if Sima Yi would feel this way, but it was about whether he could attack the Yellow River, and he couldn't pin his hopes on Sima Yi's carelessness or incompetence.

If these straw men could move......

Liu Yi looked at the straw men tied up by the soldiers, his heart suddenly moved, and he hooked his finger at Wei Yan in the distance: "Wen Chang, come here!" ”

"Governor, what do you command?" Wei Yan ran over and asked.

"Go and prepare some fine logs, the humble kind, and then prepare wheels for these straw men." Liu Yi thought for a while and waved his hand and said: "You don't have to worry about these things, just prepare things, and send another 2,000 people over, I will be useful, in addition, transfer 10,000 soldiers and horses from the mountain, enter the camp during the day, and leave the camp at night, repeatedly, making the illusion that soldiers and horses are constantly coming in." ”

"Whoa!" Wei Yan was a little puzzled, but he still nodded in agreement and bowed to leave.

Liu Yi returned to the tent and took out a scroll of drawing boards, this big camp was designed by him, it is not a big problem to add some pedestrian tracks to it, and then color the straw man or directly get a piece of paper armor out, the effect will be more realistic, as for whether he can deceive Sima Yi, the old silver coin, Liu Yi is not too sure, but whether it is a war, it is to deceive each other, since Sima Yi has prepared a killing move and has been seen through by himself, it is a pity not to take advantage of it, it depends on who can deceive whom.
