Zhang Yi did not think of flooding Jinyang City, in the army, in accordance with the practice of fighting in various countries, he brought five or six sailors, and this sailor was to be used when preparing to flood the city when fighting on the battlefield. Because, at this time, all the cities in the world are built next to the river, otherwise where would they get water to drink?

Since castles are built next to water, water workers may come in handy in battle. Take it with you in the army, be prepared.

Zhang Yi knew that this was the most basic common sense, and when he set off for the battlefield, he didn't need to command himself, and the logistics captain in the natural army would think of it. Moreover, the troops on their own side also need to get water to drink, and they will also rely on the supply of water sappers.

However, Zhang Yi thought of the fighting habits of the Linhu people, these people are used to coming and going freely, let them take off their battle robes and go to the upper reaches of Fenshui to build a dam, how can they do this? Without the help of the Lin Hu people, and the 20,000 Qin and Wei allied troops led by Zhang Yi and Gongsun Yan, they would not have been able to build a barrage and raise the water level of Fenshui in a short time.

This is a big fortification, Zhang Yi hesitated, he did not immediately order to prepare to besiege the city with Fenshui, and thought: "I'm waiting and seeing, when it's really a last resort, I can also try this method." At that time, if the Linhu people do not agree and still lure them with their goods, they have always coveted the goods of the Central Plains, which should make sense. ”

Zhang Yi felt that it was not yet a helpless moment to divert water to irrigate the city, so it was not worth spending a lot of money to lure the Linhu people to participate in the dam building. Moreover, the Linhu tribe sent their wolf cavalry army, all of whom were high-eyed and full of spirit, and they were not easy characters to deal with.

Zhang Yi's troops in the south of the city, led by Mantuo, numbered more than 20,000 people, and were pure Lin Hu wolf cavalry. The reason why he arranged it this way was also because the south could become another direction to break through.

If the crown prince of Zhao went west or north, he would leave Handan farther and farther away, and instead enter the territory of the Linhu people, and they might fall into a situation of being passively beaten, which would be very disadvantageous.

However, if you break through from the south, you will still return to the original road, and take the road from Huotai Mountain to Handan, although it is a little farther away, but it is also in the direction of Handan.

Zhang Yi took a lot of hesitation when he chose Gongsun Yan or Mantuo to guard the south of Jinyang City. It's a dilemma.

The advantage of choosing Gongsun Yan is that he is a native of the Central Plains, and the battle will be in accordance with the usual tactics of the Central Plains princes, and when arranging troops, he will take into account the quiet slip of the enemy in Jinyang City to break through the siege, and strengthen the sentry and alert troops.

However, the disadvantage is that the Wei army led by Gongsun Yan is only 10,000 people, and it is difficult to stop the enemy in Jinyang City, which is several times larger, from breaking through suddenly. Therefore, it is obviously extremely risky to arrange for Gongsun to defend the south side.

And if Pai Mantuo leads the Lin Hu Wolf Cavalry to defend the south of Jinyang, there is no need to worry about the troops, and the Wolf Cavalry itself is also very strong in combat. However, the biggest drawback lies in the combat habits of the Linhu people, who attack strong and defend weakly, and are accustomed to attacking, but they will neglect to take precautions.

After neglecting to take precautions, the enemy in Jinyang City had an opportunity to take advantage of, and if they chose to slip away quietly from the south, the Lin Jackal cavalry would probably not have time to react. However, Zhang Yi immediately thought: "The cavalry units of the Linhu people have always been known for their lightning-fast pursuits, even if they are half a beat slower, as long as the enemy does not flee far, they can catch up. ”

After careful consideration, Zhang Yi chose Mantuo to lead 20,000 wolf cavalry troops to garrison the south of Jinyang, and he repeatedly told Mantuo to be extra careful of the prince of Zhao in the city sneaking away, and instructed him: "Be sure to arrange more sentry posts and keep an eye on the movement at the south gate of Jinyang City." ”

Mantuo agreed, and he replied to Zhang Yi through the translator: "Zhang Cheng, Prime Minister of Qin, you are too worried, with the courage and strength of our Lin Jackal cavalry, forgive him and the prince of Zhao State will not dare to challenge our military might." If they dare to come out of the south gate, I will tell them to come and go, not only will there be no armor, but even no bones will remain. ”

The translator conveyed Mantuo's words to Zhang Yi, Zhang Yi looked at the high-spirited Mantuo, his brows couldn't help frowning, he regretted his decision to let Mantuo garrison the south of Jinyang City. scolded in his heart: "These arrogant guys really think that they are invincible in the world!" ”

At this time, Zhang Yi still did not know that the combined column army led by Qu Xin and Zhou Shao was divided into two routes, and one of the troops was being led by Qu Xin to Jiyi City, which was dozens of miles away. did not estimate this situation, Zhang Yi made a fatal mistake in the deployment of troops: he sent Mantuo to the south of Jinyang City.

At this time, Mantuo was in a very arrogant and complacent state of mind, which reached its peak when Zhang Yi was ready to ask the Lin Hu people for more troops with bribes.

Mantuo inevitably looked down on the princes of the Central Plains: "You useless things deserve to be plundered by us, and the grain you grow and the splendid embroidery you weave should be in our pocket." Who told you to be so unhelpful? Even if you capture the prince of Zhao Kingdom, you have to completely rely on the wolf cavalry of our Lin Hu people! ”

Mantuo thought to himself: "Look at you, the so-called prime minister of the Qin State, Zhang Yi, and the so-called Gongsun Yan, the general of the Wei State, you are so careful and worried to death." It's because you can't do it. With the little strength of the prince of Zhao, they have reached this wilderness, and they must not be the meat of the Lin Jackal cavalry, and let our sharp blades slash and slaughter. ”

That night, Mantuo did not send patrol sentries according to Zhang Yi's instructions, but the habit of the Lin Jackal cavalry, after a big battle, they always had to drink wildly, **** shouted arrogantly, in order to relieve the depression in the chest and relieve the fatigue of the battlefield.

Mantuo sent out more than twenty knights to stand guard, and these people were divided into four groups and took turns to keep watch. Helplessly late at night, this sentry can't help but ****, and joins the ranks of indulgence, where is the heart and strength to sentry?

Zhou Shao, who went out of the city from the south gate, was originally extremely cautious, for fear of alarming the Linhu cavalry stationed in the south of the city, but he sent the guards who went to scout and came back one after another to report: "I didn't find the sentinels of the Linhu people." ”

Zhou Shao was puzzled in his heart, pondered for a while, figured out the reason, and couldn't help but be overjoyed in his heart, he found a rare gap that protruded from the siege.

Zhou Shao walked less than three miles in the direction of Jiyi City, and he was completely relieved, and he was sure that the Lin Wolf Cavalry was not the kind of army that paid attention to deployment and control.
