Dianman walked away wearing a pair of two-inch nail-toothed clogs, and his feet were much sharper in the mud.

Back in the area where the military officials were settled, it was gloomy and bleak.

As military officials, they have dry military tents in the rain to shelter from the rain; The ordinary troops migrated to the area of Fangcheng in the rain.

After these military officials investigated their subordinates, places of origin, resumes, and some information about the rear of the Wei State, they moved to the rear for resettlement.

Tian Xin's engagement, Zhou Bai saw that Dianman returned to the small tent for his exclusive use without saying a word, and said to the military officials guarding here: "Keep an eye on him, loose on the outside and tight on the inside." If he escapes, he will be behind him and find out the tunnel. ”

"And if this man flees?"

"The king indulges in the forbidden like a pigeon in a cage, and is he afraid of getting rid of a pawn?"

Zhou Bai's tone was casual, and before leaving, he instructed: "Searching the tunnels of the thief army is related to the safety of our army's grain storage in the future, so you must not be careless." ”

Several military officials agreed one after another, and Zhou Bai put on his coat and led a group of captured military officials to interrogate.

Now that the fighting has not long stopped, the vast majority of the Wei army officers are in a state of ignorance and are easy to interrogate.

In this way, the continuous selection of people for review can constantly exert pressure to oppress the middle and high-ranking military officials who are hidden among the military officials, forcing them to reveal their deeds or take the initiative to admit them.

On the other side, Guan Yu fell into a state of anxiety again, and Tian Xin suspected that the Wei army was digging tunnels, which was not groundless speculation.

Le Qi is such an obvious general, and his personal army team disappeared from the sight of the enemy and us, either hiding in the hidden soldier cave, or taking the tunnel to break through.

Not to mention Zhang Liao, if he changes himself to manage the Wankou defense line, he will also dig tunnels to prepare for future defenses, counterattacks, and attacks.

If there are really such one or two tunnels, it is tantamount to exposing the heart, allowing the Wei army's short inch of iron to resist the heart, and after the Wei army is ready, it can launch a fatal blow from the inside.

But it has already begun to rain, and the traces of Leqi's escape will be covered.

Now only by defeating Zhang Liao and capturing Zhang Liao's close staff and military officials can we obtain authentic information; There is also Zhang Liao's protector Wu Zhou, who broke Kunyang City, and could also interrogate and learn about the hidden military information related to the tunnel.

Even if such a large-scale project takes more than a year, there are signs to be found.

Guan Yu was also holding a meeting here, and Xiahou Lan, who was good at civil engineering, spoke: "The thief army will dig out a large amount of soil and stone when digging tunnels, and Zhang Liao will conceal and cover up the construction of the tunnels. Previously, I was puzzled by Zhang Liao's purpose of building the earthen building, but now it seems that it should be a chaotic move. ”

Xia Houlan's expression was serious: "The last general thinks that the siege of Kunyang should be released and the thief army should be allowed to evacuate." ”

The Wei army has an authenticity, and the Kunyang defenders have been in contact with the various departments of the Wei army, and it is not a lone army that does not know how to cooperate with the news, but an army with the enthusiasm to cooperate.

However, due to the rain, Zhang Fei's troops were tired of marching, and more than half of the right army was left behind, so it took time to rest and recuperate, and it also took time to set up siege positions.

Therefore, in terms of time, the siege of Kunyang is a virtual reality, and Zhang Fei does not have his own strong camp, nor does he have fortifications to isolate Kunyang.

In this state, Zhang Fei is dangerous.

Guan Yu thought about it carefully, if he easily indulged the retreat of the Kunyang defenders in a negotiated way, it would definitely make Zhang Fei unhappy.

After thinking about it again and again, Guan Yu had a lot of concerns: "This move will damage the spirit of our army, if you send someone to negotiate with the Kunyang defenders, the defenders will despise our army, be arrogant, and will give birth to a heart of perseverance, which is not conducive to attacking." ”

I was reluctant to let the nearly 10,000 young and strong soldiers of the Wei army in Kunyang City, and I was reluctant to let Sun Deng, a big fish, escape.

grabbed Sun Deng and grabbed Sun Quan's throat.

As Tian Xin's strategy arranged, grasping Sun Deng can split Jiangdong and Wu.

Guan Yu saw that Xiahou Lan still had something to say, so he turned his head sideways to look at Yu Translation: "What does the right army think?" ”

Xia Houlan is a general who was born as a military officer, and he is dignified on weekdays, and he will definitely be responsible and insist on whatever he says.

Guan Yu didn't want to quarrel with him, the older the general, the more stubborn he became, he cherished time and opportunities, and he didn't want to take the initiative to back down.

What can the Right Army think?

Zhang Fei ran so far to participate in the battle, so it was naturally impossible to easily give up the Wei-Wu coalition army in Kunyang City; The Wei army broke the rules and shot Yu Zhong to a serious injury, Yu Fu naturally supported Zhang Fei, and he couldn't wait to follow Zhang Fei to rush into battle and vent his anger for his son.

Xiahou Lan saw that Yu turned to fight for the right army, and the words choked in his throat were swallowed into his stomach with difficulty, and his face was not very good-looking.

If the tunnel problem is not solved, there will always be hidden dangers in all departments of the Han army.

But Zhang Fei and Yu Chuan have the confidence to investigate the area where they are stationed; Guan Yu also has it, and it is estimated that Ma Chao also has it, so Xiahou Lan has nothing to say about it.

Nowadays, there is a mature tunnel excavation technology, and when the Guanzhong area was built in the Guanzhong area during the Wudi period, the water flow would be washed out and soaked in the loess embankment.

Multi-point excavation shafts are adopted, and culverts are excavated horizontally under the shafts, and water is diverted through the loess layer by culverts for irrigation.

With the westward expedition of the Han army, this technology is also widely used in Liangzhou and the Western Regions, and the karez of the chariot division is the application of this kind of technology.

As long as the camps and strongholds of Zhangliao's armies are determined, and the information is transferred, and the clues to the tunnels can be found according to the map.

It takes time and waits for the weather to clear.

To attack Zhangliao or Kunyang, you need to wait for the rain to stop before you can do it.

And now the safest thing is to gather the army to increase vigilance, prevent the Wei army from attacking, and divide the battlefield, otherwise the Wei army will destroy the scattered and trapped Han troops one by one with more strikes and fewer blows, and then trigger a decisive battle against the disadvantage of the Han army.

Before the end of the rainy season, before the arrival of Liu Bei's army group, before the Wei army tunnels were destroyed, this kind of thing was likely to happen.

As time goes on, the greater the probability that the Wei army generals will attack and invade.

The tunnel really exists, this is Tian Xin's prediction caused by Le Qi's disappearance, and it is also Xia Houlan's intuition, everyone who knows Wei Jun should know this.

The Wei army was good at civil engineering work, and each army and battalion would have been equipped with a professional engineering team with as few as forty or fifty people and as many as 100 people.

The Han army also has a professional engineer corps, while the Wei army is more professional, with high-tech positions such as Captain Touching Jin and General Faqiu Zhonglang.

Unfortunately, when Zhang Liao followed Lu Bu, Lu Bu at that time was responsible for helping Dong Zhuo dig up the tombs of the nobles of the Northern Mountains.

For civil engineering, Zhang Liao is not only no stranger, but also very handy.

Digging a grave is actually the same thing as digging a tunnel, and it is in the same vein in terms of equipment and technology.

Xiahou Lan saw that he couldn't convince Guan Yu, and he was even more powerless to persuade Zhang Fei and Yu to retreat...... Zhang Fei and Yu Tuo are two people with similar temperaments, and they typically don't listen to persuasion.

You can still reason with Guan Yu, but you can't reason with Zhang Fei and Yu Tuo.

With apprehension, Xiahou Lan came to the Beifu military camp outside the city after the meeting.

The rain soaked his rough silk cloak painted to prevent rain, and Xiahou Lan roasted the fire in Tian Xin's military tent: "Junhou, now the Duke of Song and the Duke of Wei are beyond words to persuade, if they persuade again, I am afraid of angering the second duke." ”

Tian Xin just laughed when he heard it, Guan Yu's personality was already somewhat restrained, and now he was mixed with Zhang Fei and began to follow Zhang Fei to make trouble.

It is said that Zhang Fei is thick and fine, and he is a person who is discerning...... But it also shows that Zhang Fei's style is usually rough, and he will not awaken his insight ability until he is headwind.

He has already offended Ma Chao and Ma Liang, and it is difficult to persuade Guan Yu through Ma Liang.

I can't persuade Guan Yu now, Guan Yu is a person who wants to save face, and he is already guilty because he was ambushed and almost died in battle, you can persuade Guan Yu that this battle can't be fought like this, you have to fight like that...... How could Guan Yu listen? I know you're right, but I'll still take chances and give it a chance.

Zhang Fei feels guilty, and may admit his mistake with you seriously, but in fact, he apologizes in one sentence; But Guan Yu won't, at most, he will twist and pinch the clouds, the breeze is light, it is not painful or itchy, he will not discuss this matter in depth, and he will hold on to the end.

has already seen through Guan Yu and Zhang Fei, Tian Xin is very helpless at this moment, and his mind is more ridiculous.

Character determines fate, if you follow Xiahou Lan now, you can persuade Guan Yu again...... In the old man's opinion, this is a question of his prestige as a commander, which is very fatal.

How many people insist on going their own way in order to prove the sentence 'I can do it', and end up losing and going bankrupt?

Contrary to Tian Xin's expectations, Xiahou Lan's tone changed: "For today's plan, I also ask the prince to move the town to the east to cover the army of Xiahou Shang, Cao Ren, and Cao Xiu for the Duke of Song." The prince and the Duke of Zhao guarded the flanks of the army, and the Duke of Song and the Duke of Wei besieged Kunyang, even if they lost, they would not damage the fundamentals. ”

The Beifu soldiers moved to the northeast, and Zhang Fei and Guan Yu had to face only one remnant army Zhang Liao, nearly 10,000 besieged Wei troops in Kunyang, and Cao Hong in the northwest.

Cao Hong is easy to deal with, Cao Ren is a famous general of the Iron Wall, then Cao Hong is a famous general of the Iron Guard...... The field ability is mediocre, lacks commanding power, and is far less acute than Cao Xiu, Xiahou Shang, Cao Zhang, and Cao Zhen.
