After Zhao Feng heard this, he calculated a little in his heart.

Jing County is not too far from Mi County, and at this rate, it is estimated that it will take about two days to reach Mi County.

Then he told Xu Shu about Xinzheng's situation completely, and then asked: "Yuan Zhi thinks, how should Xinzheng guard it now?" ”

Xu Shu pondered for a long time, and waved at Zhao Feng: "Return to the general." ”

"From Yishu's point of view, although the Xinzheng city wall has collapsed, if Cao Jun is really short of boulders, even if he only needs to attack the city twice, he can completely smash the Xinzheng city wall, then there are still about five days of preparation time."

"According to this time, there are two strategies for the general's reference."

Zhao Feng was happy in his heart, there is a plan, it is better than nothing, not to mention that there are two strategies: "Come and listen!" ”

Xu Shu waved at Zhao Feng: "Huh! ”

"First, in three days at most, the catapult can be transported to Xinzheng."

"Among them, large catapults and medium-sized catapults can be placed inside the city and thrown stones outside the city."

"We don't need to smash Cao Jun's catapult, as long as we can throw a short distance outside the city, we can effectively kill Cao Jun."

"As for the boulders needed for stone throwing, there is no shortage in Xinzheng anyway!"

"The second is that the general can let Xinzheng guard the soldiers, escort the wounded soldiers out of the city, and transport a large number of stones out of the city."

"As long as the general builds a dam to cut off the flow of water in the upper reaches of the river, and destroys the dam at a critical time, the water will flow down, and the Cao army can also be effectively killed."

"It's just that it's already late autumn, and the amount of water is too small, and the new Zheng Shou General is also needed to inadvertently put some stones into the water to hide people's eyes."

"Otherwise, it's too easy to be detected by the other party!"

"In addition, this move needs to be very well controlled for the time to destroy the embankment, otherwise the previous efforts will be wasted, or it will not be able to kill Cao Jun too much."

After Zhao Feng heard this, he calculated a little in his heart, and it felt feasible.

Then Zhao Feng wanted to implement the two strategies at the same time, but after thinking about it, he felt that it was unlikely that they would be implemented at the same time.

Because of both strategies, a large number of boulders are required.

With the stock of boulders, although they can be carried out at the same time, most of the boulders are outside the city.

If Zhao Feng sent people outside the city to transport stones into the city, he would obviously not be able to hide Cao Cao's ears and eyes.

In the current situation, there are only a few possibilities that require the use of a large number of boulders.

As long as they are ruled out one by one, Cao Cao naturally knows what Zhao Feng is going to do here.

After calculating in his heart, Zhao Feng directly gave up the idea of cutting off the water.

As Xu Shu said, now that it is late autumn, the strategy of using flooding requires the cooperation of several aspects.

If you make a mistake in one link, you will lose all your efforts.

Of course, the main thing is the problem of water storage.

If it was spring, this strategy might be better than using catapults to defend the city.

After all, in terms of time, it is relatively tight.

It's just a strategy to transport catapults to Xinzheng, and the risk is relatively large.

In case Zhao Feng transported the catapults to Xinzheng, and Xinzheng happened to be lost.

Doesn't that mean giving all these catapults to Cao Cao?

Zhao Feng sighed secretly, it would be good if these catapults could be transported a few days earlier.

It's a pity that there is no what if!

Then, Zhao Feng said his thoughts and scruples, and then asked, "Yuan Zhi thinks, how should we deal with it?" ”

Xu Shu smiled and said: "Return to the general, this matter is easy to do!" ”

"Just let General Zhao Zilong lead the cavalry of the headquarters to the left of Xinzheng, and send a cavalry army to the right of Xinzheng."

"With 30,000 cavalry on the side, Cao Cao will definitely be worried that the general is ready to do anything in order to destroy the catapult!"

"In this way, Cao Cao will inevitably be around the catapult, do a good job of fortifications against cavalry raids, and deploy with a large army."

"Otherwise, once the catapults are all destroyed, even if Xinzheng is crumbling, it will still consume a lot of Cao Jun!"

After Zhao Feng heard this, he groaned.

In this way, it feels feasible to delay time.

In addition, Zhao Feng felt that Xu Shu had another intention, that is, when it was really a critical time, these 30,000 cavalry should destroy Cao Jun's catapults.

Even if the 30,000 cavalry were buried because of this, it would be beneficial to the subsequent war.

At the very least, the Cao army, which did not have catapults, had at least one to two casualties on both sides when attacking the city.

In this way, it is completely necessary to drag down the pace of Cao's attack.

Of course, if you want to calculate the gains and losses strictly, 30,000 cavalry can at least compare to 120,000 infantry troops!

After all, cavalry is not only difficult to train, but also difficult to become an army, and the yield rate of war horses is not high.

In comparison, 120,000 infantry can be recruited in two years, and if you ignore the population structure, you can recruit them in one time.

In terms of cavalry, horse farms are needed to produce war horses, and war horses need to be introduced from all aspects.

For strategic materials such as war horses, it is commendable to be able to purchase 10,000 horses from the Xiongnu a year.

After all, in order to prevent the Huns from training adult war horses and leaving any secret hands, Zhao Feng bought foals and trained them by himself.

It can be seen that under normal circumstances, it takes four or five years to train 30,000 cavalry.

Zhao Feng pondered for a long time before he spoke: "At present, it seems that it can only be like this. ”

Then he waved his hand: "Yuan Zhiche Ma is tired, and a banquet will be set up later for Yuan Zhifeng to wash the dust." ”

"Let's go down and get some rest."

Xu Shu waved at Zhao Feng: "Huh! ”

After speaking, he withdrew from the Chinese army's big tent.

After Xu Shu left, Zhao Feng looked at Xiong Da: "Send someone to order Zhao Yun and ask him to lead the cavalry and camp near the north gate of Xinzheng first." ”

"As soon as Cao's army is ready to attack the city, let him lead his troops to appear on the right side of Xinzheng."

"In addition, Wei Yan was ordered to temporarily lead 15,000 cavalry and garrison outside the northern gate of Xinzheng."

"As soon as Cao's army is ready to attack the city, let him lead his troops to appear on the left side of Xinzheng."

Xiong Da bowed his hand to Zhao Feng: "Huh! ”

After speaking, he turned around and withdrew from the Chinese army's big tent.

In the blink of an eye, two days passed.

In the past two days, Cao's army did not attack Xinzheng, and Tai Shici estimated that it should have prepared a boulder.

Judging by the past situation, it should be in these two days, Cao Jun will lead his troops to storm Xinzheng.

Fortunately, although the time is pressing, it is still under control.

this day.

Xu Shu walked into the big tent of the Chinese army and waved at Zhao Feng: "General Qiqi!" ”

"The students of the Mo family, carrying all kinds of catapults, have arrived outside the barracks."

"Does the general let the Mo family students enter the barracks and then observe the catapults, or let the Mo family students directly escort the stone throwers to Xinzheng for defense?"

Zhao Feng said with a smile: "Time is pressing, let's go out of the camp together and take a look!" ”

After speaking, he stood up and walked out of the Chinese army's tent with Xiong Da and Xu Shu.
