The battle of Guandu, this time compared with the previous one, it was very different.

In this battle of Guandu, the soldiers and horses on both sides have already crossed the banks of the Yellow River, so ferries such as Yanjin are no longer important.

Moreover, the armies of both sides were drawn from the battlefield of Yuzhou and retreated to Guandu.

Cao Cao did not need to attack these ferries, and if Liu Wei was defeated, even if he retreated and abandoned Yuzhou, it would be enough to go west to Luoyang.

Crossing the Yellow River north to Jizhou is simply not needed.

Besides, not to mention that there is no need to cross the Yellow River this time, even if it is necessary, with the length of the Yellow River, it is almost possible to cross the river by boat.

Such a long front is obviously a thing that will outweigh the losses.

None of this time is needed, so there's no need to think about it.

Guandu is located in the upper reaches of the chasm, bordering the Bianshui, which is the barrier to the northeast of Xuchang.

The barrier in the northeast of Xuchang, in addition to the chasm as the moat, is also backed by the mountains of Xuchang, and also near Luoyang.

Liu Wei also knew that this was why Cao Cao chose to move the capital to Xuchang in history.

The purpose is that because of Xuchang's position, which is close to Luoyang, it can be accepted by those Hanchens to a certain extent, and there is a buffer.

And the barrier in the north can prevent Yuan Shao from attacking, after all, Yuan Shao's power was huge at that time.

"Feng Xiao, I understand what you said, but why did you suddenly study this?"

Liu Wei looked at Guo Jia and saw that all the mountains and rivers in his map this time were in the north of Xuchang, close to Guandu.

"Your Majesty, gunpowder is very powerful, but if you want to exert its greatest power, you need to use the power of the valley."

Liu Wei was a little familiar with it when he heard it, and soon he thought that when Zhuge Liang was on the Northern Expedition, he almost burned Sima Yi to death in the upper valley.

However, the sky is endless, Sima Yi survived in the end, and Zhuge Liang fell short.

I have to say that these smart people think about problems really strangely similar.

If you use gunpowder yourself, if you can really lure Sima Yi into the mountains and forests, or the valley is indeed better to deal with.

Moreover, he can use gunpowder to blow up the mountain rocks, and once Sima Yi enters the valley, he can directly seal the valley.

In this way, he Sima Yi will become a turtle in the urn, as long as he is trapped in the valley, what does it matter if it rains or not.

"In that case, is there a suitable place for Feng Xiao?"

Liu Wei asked after understanding Guo Jia's thoughts.

"Ziyun Mountain and Shoushan Mountain." Guo Jia looked at these two openings and said, but he also frowned, as if there was something difficult to choose.

"Could it be that there is something wrong with it?" After Liu Wei saw it, he naturally looked at Guo Jia and asked.

If there is anything, then it is natural to say it and solve it together.

"This Ziyun Mountain and Shoushan are both famous mountains in Xiangcheng, and Xiangcheng is also a county in Yuzhou."

This Ziyun Mountain and the first mountain are both big mountains, and this Ziyun Mountain is famous for the purple clouds that often come out of the top of the mountain.

This mountain is located in the south of Xiangcheng, that is, almost in the north of Xuchang, but it is more westerly.

This mountain is famous because of the remnants of the Funiu Mountains, and it can be said that this is the Funiu Mountain System.

After Liu Wei understood, he still didn't understand, but what was the difference between the two?

"This Ziyun Mountain is closer to Guandu than this mountain, but this Ziyun Mountain has never had a suitable valley." Guo Jia saw Liu Wei looking at him, he immediately understood, and then replied.

As soon as Guo Jia said this, Liu Wei naturally understood.

Since Ziyun Mountain is near, then the reverse means that this mountain is relatively far away.

If this is the case, then naturally it needs to be considered, and looking at Guo Jia's worries, I am afraid that this mountain has a suitable valley that he likes.

"If there is no suitable one, then why don't you just use another method and take a city as bait?"

Liu Wei also knew Guo Jia's hesitation, so he looked at Guo Jia and said.

With the power of this gunpowder, it is very difficult to blow up a city, and the quality of the ancient city is very good.

Otherwise, how can we withstand the ravages of this war?

At least he hadn't heard of a city that had fallen because of the siege.

Since Guo Jia is embarrassed, then he can only think of other ways.

If you choose the nearby Ziyun Mountain, then there is no suitable valley calculation Sima Yi chose this mountain.

Then this is a very difficult thing to lure Sima Yi's army over.

In the current situation, there is no room for error, otherwise it will be a complete failure.

It's a contest between wise men, and sometimes it doesn't take much else.

Because they know each other, how to find out each other's most critical lifeline.

So there's no need for them to waste time like headless flies.

"Your Majesty is talking about Yangge City?" After Guo Jia listened to Liu Bian's words, he didn't seem surprised at all, and he also looked at Liu Bian and asked.

What does this mean, obviously this shows that this Guo Jia has not considered this, and for this he even considered the city.

"Not bad." Liu Wei nodded, indeed, the first thing he thought of was indeed this city.

Because this city is a small city, but it cannot be said that it is not a big town.

"It's still Shoushan." Guo Jia finally said with a solemn face.

"If you want Sima Yi to lead the army into the Shoushan, then you must have a fatal enough temptation, otherwise, it is impossible for Sima Yi to enter the inner valley of the Shoushan."

Liu Wei looked at Guo Jia and persuaded him, he felt that Guo Jia should still think about making a decision.

You must know that in history, Zhuge Liang spent a lot of thought in order to lure Sima Yi into the valley.

Although it is said that Sima Yi was much older at that time than now, he has become more calm and experienced in many things.

But this does not mean that the current Sima Yi is a brainless person.

Even if Sima Yi is still young now, so he sometimes takes risks, but that must be tempting enough.

Without enough temptation, why should he Sima Yi take risks?

"I use myself as bait, I think Sima Yi will be interested, right?"

Of course, Guo Jia also knew what Liu Wei said, so he also understood that what Liu Wei said was reasonable.

Even if you don't have a big enough interest to achieve a certain effect, you won't easily do something risky.

This person is originally interested in seeking advantages and avoiding disadvantages, and only if there is enough temptation, once success can bring earth-shaking changes, can he move people's hearts.

"In this way, don't you want to be in danger, once this gunpowder explodes, it will be difficult to control this power at all."

Liu Wei looked at Guo Jia and said, he himself is not sure of this at all, who can control the power of gunpowder.

In my previous life, except for being on TV, except for setting off firecrackers, I had never tried this dose of big guys.

"I know, it's just that if there is not enough temptation, how can Sima Yi take the bait." Guo Jia looked at Liu Wei and nodded.

Of course, he knew that there was no way to control the power of this gunpowder.

If it was so easy to control, Liu Wei would not have looked so far away when he experimented.

It's just that there are some things that have to be done on his own, so he won't back down.

"What if I don't agree?" Liu Wei looked at Guo Jia and said coldly, he didn't want Guo Jia to take risks.

"Your Majesty, Feng Xiao has never asked Your Majesty, and this time I ask Your Majesty to fulfill it, but Feng Xiao can promise Your Majesty, and I will definitely come back alive."

Guo Jia looked at Liu Wei and said, his face was solemn, but he still had that faint smile when he said the second half of the sentence.

"You..." Liu Wei wanted to say something, but he couldn't open his mouth.

If you stop Guo Jia by yourself, will Guo Jia agree?

Obviously, Guo Jia will not agree, and he is ready to fly, what can he do.

Even if he ordered a retreat and gave up Yuzhou, Guo Jia's character, although it seems to be eclectic, he will not obey orders.

At least in this matter, he won't listen.

"Everything will be done as you say, but you have to remember what you say." Liu Wei sighed, closed his eyes and said.
