Ma Chao's main formation was only three miles away from the Wei army's defense line, very close, standing on the bank of the Lishui River, and on the side was a dam that was still being built, heightened, and consolidated.

With the current water storage capacity of the dam body, it can meet the normal transportation of equipment.

It is still being reinforced, not because of the fear that the flood will wash away the dam, but because it is afraid that the dam will not be durable and will not be able to store too much floodwater.

The dam spread to the shore, like a low wall used by the Han army for defense.

The only way to do this is to accumulate a large amount of flood water and wait for the flood water to burst through the dam and sweep it down...... As for the water gate built by the Wankou defense line, I am afraid that it will not be able to discharge the flood, and it will be washed away by the flood, and a huge gap will be washed out.

You can't expect to win by floods, but the rainy season can come at any time, so be prepared.

When the autumn rain broke out, it was impossible to attack the fortifications, just as the flood broke through the Wei army fortifications, as long as it broke through a gap, it could tear and chisel through the Wei army's defense line.

"The Wei army is waiting for the autumn rain."

Tian Xin and Ma Chao made tea in front of the battle and told their opinions: "After the heavy rain, it is not conducive to the advance and interspersing of our army. At that time, one of Cao Zhen and Cao Zhang in his pass will lead the army to the Central Plains to help in the war, and the other will take the Wuguan Road to invade Nanyang. ”

It was all something that was analyzed before the war, and now it is only judged according to the performance of the Wei army: "The fact that the surrounding area around Wankou is not disturbed by the northwest and southeast winds in autumn and winter is a bad thing for our army." ”

Ma Chao bowed slightly, squinted his eyes and looked at the Wankou defense line in the distance, and his tone was regretful. said a nonsense in Tian Xin's eyes: "It's a pity that there is no wind." ”

Funiu Mountain blocked the northwest wind, and the southeast wind could not blow.

In the Wankou passage in the southwest and northeast, neither the Han army nor the Wei army could occupy the upper hand.

The upwind outlet is very important, and whoever holds the upwind outlet will naturally have many conveniences when fighting.

Not to mention anything else, your own bow and crossbow can have an extra range of 20 steps, and the crossbowman's line of sight is not disturbed by dust and poisonous smoke, is this a big advantage?

There is also Tian Xin's lime tactics, and I don't know if Wei Junzhang has mastered it, if his side is upwind, he will use a trebuchet to shoot lime bombs when attacking the city.

Exposure is exposed, who will keep the hole cards in the decisive battle?

At a speed unexpected by the Wei army, he tore through the defense line, interspersed, and broke through, dividing Zhang Liao's headquarters, and even blocking Zhang Liao himself in Yexian.

If the Wei army is one step behind, it will fall behind step by step, and the initiative is in the hands of the Han army, as long as you don't make mistakes, you can lead the Wei army by the nose.

Unfortunately, the autumn rain is coming, and the Han army has a tendency to be passive.

As for the reason...... Tian Xin glanced at Ma Chao a few more times, but Ma Chao didn't seem to notice it and didn't respond.

There was no wind near the battlefield, and many tactics were no longer ready to be used, and they did not have to guard against fire attacks launched by the Wei army taking advantage of the wind.

Ma Chao was thoughtful, and looked at the Wei army's defense line from time to time, as if he could see through it.

Tian Xin saw that he looked like he was not here, and he didn't care, anyway, he wouldn't be able to eat the lamb slaughtered by Zhao Gongchao himself in the future.

didn't care, Tian Xin drank tea by himself, thought about his flaws, and looked at the surrounding layout.

In addition to the necessary vigilance troops, the remaining troops and manpower were either put into transportation, or dams were reinforced, or trenches were excavated, and fences were filled in to prepare for the subsequent siege.

This is just an old plan to move step by step, and it is not a novel tactic, and it is better to be safe.

The defenders of the Wei army's defense line are indeed in full array.

The defenders in the west had a certain belief in Zhang Liao, and it could be said that they were full of spirit and in good condition; Eastern Defenders...... It can almost be regarded as Zhang Liao's targeted consumption of troops.

After this bloody battle, the eastern defenders will either die or gain the trust of the Wei army...... Either surrender to the Han army.

However, since they have all been deployed to the eastern region, it means that the family members and the rear have corresponding countermeasures, and the Wei army in the eastern defense area may have been warned, and they know what the consequences of surrendering the Han army will bring to their families.

The Wei army cannot be expected to surrender, nor can it be delayed until the autumn rains flood...... The autumn rains were flooding, the mud was everywhere, and the army was so strangled that it was almost impossible to move.

The year before last, the Wu army suffered the loss of autumn rain under Jiangling City, giving Guan Yu the opportunity to withdraw calmly.

So it is necessary to open the situation before the autumn rain, without his own assistance, what kind of way will Ma Chao use to open the situation?

I can't figure it out, Tian Xin saw that Ma Chao always looked alienated from himself, as if he had come here to steal the limelight from him.

The more he thought about it, the more bored he became, and after a cursory cup of tea and a meal, Tian Xin returned to the west side of the main formation.

Boarding the green umbrella Gairong car of the formation, Tian Xin asked Li Fu, who was supervising the formation: "What is the move of the Wei army?" ”

"There is no significant change."

Li Fu pointed to the low hills full of dense forests in the northwest direction: "During the period, there were Wei army flags haunting, and they should be suspicious soldiers." ”

Tian Xinshun and Li Fu pointed out to take a look, but he didn't care, he wished that Zhang Liao would lead his troops out to fight with him.

The Eighth Army of Beifu took turns to rest, and today it is to come out and stand here to deter the Wei army and protect Ma Chao's flanks, so that Ma Chao can build the front-line camp with high efficiency.

If the camp on the bank of the Lishui River is repaired, then the follow-up materials will be transported from the Lishui, and the other camps will expand and spread to the west, and they can also form a thirty or fifty-mile joint camp, which is connected by Yongdao, so they are naturally not afraid of the Wei army's counterattack and harassment.

Pang Lin, Yang Yi, Meng Da, and Xu Zuo took turns to rest and came to Tian Xinrong's car to inquire about the battle situation.

Meng Da didn't treat Ma Chao very well, frowning and unhappy: "The left army opened the way, at least five days later than expected. Now that autumn is coming, the weather is not good for our army. ”

Xu Zuo smiled and sarcastically: "You can't complain about the left army, the left army just wants to seek stability." Our army calmly camped here, all thanks to Zhao Gong's effective planning. ”

Ma Chao's advance speed was a little slow, and many things that should have been done by the auxiliary army and the conscription Ding Zhuang were completed by the left army itself.

The original plan was for Ma Chao to take the lead and move forward quickly along Lishui; Tian Xin advanced along the Jingyu Chi Road, defending the flanks for Ma Chao, as if the crab's claws stood in front of Zhang Liao.

I don't know what Ma Chao is worried about, every time he advances twenty miles, he will take the trouble to build fortifications, as if Zhang Liao will gather the main force to set up an ambush and attack with heavy fists to defeat him.

The more he built the fortifications, the slower he progressed, and he came and went at least five days later than expected.

In the face of the autumn rain, five days is not a long time, but it is not a short time.

If you want to save the five days of delay, you have to fight with more lives.

It was precisely because Ma Chao's style suddenly became stable that Guan Yu had to urge Tian Xin, who should have been a latecomer, to speed up his march, cross the scout blockade line, and arrive at the forward battlefield almost in equal order with Ma Chao.

Now the Beifu soldiers are standing still, Ma Chao urgently builds a camp, and at dusk, the Beifu soldiers have to retreat fifteen miles before and after dark, and return to the camp...... For an armoured, heavily armed army, fifteen miles away.

Meng Da didn't want to see Ma Chao, Xu Zuo also didn't like Ma Chao a little, Pang Lin was the prison after all, and asked a few times: "Xiahou, how does Zhao Gong reply?" ”

"I'm at odds with him."

Tian Xin didn't hide it: "Zhao Gong is a person who wants to save face, and he wants me to open my mouth to help in the war." Since he was afraid of being close to each other, I simply kept silent. ”

"Haha! He is not satisfied, and he still wants to emulate Song Gong to be the minister of the Han Dynasty? ”

Meng Da's laughter was rough and short, and his tone mocked: "Xiahou, what should our army do?" ”

Xu Zuo and Yang Yi also laughed, and Pang Lin persuaded: "This state affair, why did Xiahou abolish the public because of private affairs?" ”

"Pang Gong's words are inappropriate."

Tian Xin squinted and looked around: "Since Your Majesty has arranged for me and Zhao Gong to be each other's faces, then Zhao Gong should not be secretly suspicious. ”

"He cares about the long-term, why shouldn't I?"

"Let's talk about business, isn't it official that our army has been running for hundreds of miles to shield the enemy army in the northwest? At this point, it is impossible for our troops to stay in place and continue to defend the flanks of the left army. ”

Meng Da and Xu Zuo smiled, seeing that Tian Xin didn't look like a joke, they looked at each other and kept them in their hearts.

Pang Lin was also helpless in his eyes, Ma Chao didn't dare to continue to get close to Tian Xin, for fear of getting into trouble, did he force Tian Xin to give advice to Ma Chao?

Or let the Beifu soldiers risk being attacked by fire and night attacks, and stay in the wilderness in a state of exhaustion?

Pang Lin smiled bitterly and was dumbfounded, and Tian Xin said: "This time is different from the past, but our army can still run rampant in the Central Plains!" Zhao Gong has his own measurements, and our army should also have our army's tactics. ”
