After handing over the task of defense to the Silver Pegasus Knights who rushed over, Ning Yuan and the mermaid warriors occupied the magpie's nest, burrowed into the barracks of the demon warriors, and fell asleep.

Last night, it was a rapid march and a head-on attack on the demon camp that had already been noticed, and everyone was tired enough, so as soon as they fell, a loud snoring sounded in the barracks.

While Ning Yuan and a group of mermaid soldiers who attacked the military camp at night fell into a deep sleep, two engineer battalions of Shenying Jin appeared on the banks of the Weishui River near Meixian and Yangling respectively.

The rat soldiers first dug several cylindrical pits more than 30 meters deep in the selected places, threw iron balls tied with thick iron chains into the pits, and then pushed hundreds of catties of boulders into the pits.

After filling it with boulders, the dwarf soldiers immediately poured the cement they had prepared into it.

After waiting for several hours, a group of silver Pegasus knights dragged a long iron cable to the other side of the Wei River, and then the sappers of the engineer battalion did the same and laid huge concrete piles on a high ground on the south bank of the Wei River.

Ten thick iron cables are at the same height to form the bridge deck of the chain bridge, and four thick iron cables are located above the iron cables on both sides, forming the railing of the chain bridge.

When all 14 of the 14 thick iron cables that make up the chain bridge were secured, a strong team of swan soldiers began to pave the deck with planks made of cold ironwood.

When the gaps between the cables were filled with planks, the sappers began to pretend to be anti-swaying chains on both sides of the bridge to prevent the bridge from shaking, and the bridge was completed.

During the rainy season, the Wei River swells so fast that no land race can cross the river except for the flying race and the mermaid race.

When Ning Yuan designed this rainy season offensive, he had already considered the problem of how to cross the river in the rainy season, and the fast, strong and durable chain bridge developed by Zu Dahai and the dwarven craftsmen was the confidence that he dared to launch an offensive in the rainy season.

Due to the heavy iron balls and boulders used as the foundation, the chain bridge can be used immediately after it is built, without having to wait for the cement slurry to dry.

It took only one day for the sappers of the Condor Army to successfully build a chain bridge in each of Meixian and Yangling, which won valuable time for a large number of Condor troops to cross the river.

As a large number of Condor soldiers crossed the river overnight with torches held high, the military camps on the opposite bank of Meixian and Yangling successfully passed the most dangerous period.

After capturing the demon military camp on the other side of Meixian and Yangling, Ning Yuan's greatest concern was that the demon clan would recapture these two strongholds while the main force of the Condor Army had not yet crossed the river.

It turned out that Ning Yuan's worries were unnecessary, and a day was simply not enough time for the nearby demon army to react.

Because the Condor Army did a very good job of secrecy when it attacked Meixian, the demon army in the west of Meixian did not know that Meixian had been lost.

So far, only the demon army stationed in Zhou Zhi has known the news that the Condor Army has called, and the fast horses they sent are now on their way to Chang'an.

But in fact, there is no need for the fast horses sent by Zhou Zhi now, because the corpses of those demon warriors who were thrown into the Wei River have already floated down the river to everywhere.

The corpses of more than 100,000 demon warriors floated all over the river, and it is believed that as long as they are not blind, they can all be seen.

Before the fast horse sent by Zhou Zhi arrived in Chang'an, the raging waters of the Wei River had already taken the lead in bringing the corpse of the demon warrior there.

When Daniels, who was stationed in Chang'an, heard a large number of demon warrior corpses rushing down from upstream, he immediately rushed over.

Seeing that the bodies of the demon warriors who had been salvaged were so swollen that they could not be recognized, Daniels suddenly clenched his fists.

Although the appearance of the corpse is no longer recognizable, the time of death can be roughly inferred.

When Daniels learned that the demon warriors had been dead for no more than a week, he immediately had a very bad premonition.

"Immediately send someone to inform Ma Feng Biao, who is guarding Hanzhong, and ask him to immediately increase his troops at the checkpoints of several main passages.

Tell him that if the enemy is allowed to enter Hanzhong through those checkpoints, Lao Tzu will cut off his head and use it as a night pot. ”

After thinking of a possibility, Daniels immediately sent people to Hanzhong urgently.

......

After a part of the army crossed Weishui, Ning Yuan immediately sent a group of cavalry to rush to Hanzhong through the Bao Slope Road, and at the same time, the vanguard of the Fox Wolf Guerrilla Regiment also followed closely into the Bao Slope Road.

Immediately afterward, Ning Yuan began to build fortifications on the opposite bank of Meixian and Yangling, preparing for the counterattack of the demon army that would come at any time.

As more and more grain, grass and troops came to the south bank of the Wei River through the chain bridge, Ning Yuan's confidence became more and more sufficient, and he was even ready to launch a counterattack directly after repelling the enemy's attack.

However, the counterattack of the demon army had not yet arrived, and the cavalry regiment that entered the Baochuan Road was the first to send back the news.

"Lord Qiqi, after two days of travel, a checkpoint suddenly appeared on a narrow valley road in front of us.

There are many demon armies stationed at the checkpoint and on the nearby mountains, and the whereabouts of our army have been discovered by the enemy, so please ask the lord for further instructions. ”

After seeing Ning Yuan, the signal soldier directly brought him a very bad news.

"If we let the Fox Wolf Guerrilla Regiments launch a direct assault, what chance do we have of capturing that level?" After listening to the messenger's report, Ning Yuan immediately asked.

"Back to the lord, both sides of that level are full of cliffs, and the walls of the level are also more than twenty meters high, as long as five thousand demon troops are stationed in the level, then it is basically impregnable." The Messenger replied very honestly.

After listening to the messenger's answer, Ning Yuan didn't speak, he came directly to the front of the map, carefully watching the terrain between Guanzhong and Hanzhong.

When he saw the Qinling Mountains standing majestically between the two places, he immediately shook his head helplessly, and said, "Let the cavalry regiment and the fox wolf guerrilla regiment withdraw first, and after they retreat, send heavy troops to guard the entrance of the Baochuan Road for me." ”

The difficulty of Shu Road is difficult to go to the blue sky.

This is a verse from the Tang Dynasty poet Li Baishu's martyrdom.

Although Li Bai's poem describes the Golden Bull Road, it can also be applied to several other passages.

What is called a husband is a key to ten thousand people, Shu Dao here is the most perfect presentation.

As long as the enemy builds a checkpoint in a difficult terrain, the attacker may not be able to pass even if it pays a heavy price.

If the enemy defending the level is not a demon army, then Ning Yuan can also send the Silver Pegasus Legion to attack.

But when the defenders in the level are demon warriors, even the Silver Pegasus Legion is useless.

The Silver Pegasus Knights have always had no opponents with their ability to ignore ranged attacks, but the Demon Clan is their natural nemesis.

Because once they encounter the demon army, they will immediately lose the ability to fly and become ordinary cavalry on the ground.

Ning Yuan had also moved the idea of letting the Silver Pegasus Legion directly cross the mountains and enter Hanzhong just now, but as soon as he thought of the possible risks involved, he immediately gave up this idea.

The Demon Clan can be destroyed at any time, but the Silver Pegasus Knights can't afford to suffer too much loss.

As a strategic weapon in siege warfare, the Silver Pegasus Knights had an irreplaceable and important position in Ning Yuan's mind, and he would rather slow down the pace of eliminating the Demon Clan than see any damage to the Silver Pegasus Knights.

Therefore, after the ground army was blocked, Ning Yuan decisively gave up the idea of raiding Hanzhong through the Bao Chuan Road.

After sending the messenger away, Ning Yuan stared at the map in front of him and fell into deep thought.

After being unable to raid Hanzhong through the Bao Chuan Road and cut off the retreat of the demon army, one of the most important problems now facing Ning Yuan was how to prevent the demon army entrenched in Chang'an from retreating to Hanzhong.

If similar checkpoints were built on several other passages such as Chencang Road, Meridian Road, and Fu Luo Road, then when the enemy retreated to Hanzhong, it would be really difficult to do it next.

Unless Ning Yuan was willing to dispatch the Seraphic Legion, it would be difficult to attack Hanzhong.

......

After the day's game time was over, Ning Yuan immediately contacted Yan Qing, the second-in-command of the Tenglong Legion.

"Yan Qing, you go to the Legion Channel and ask to see if any brothers have ever been in the Hanzhong region.

If so, you ask them, have all the passages from Guanzhong to Hanzhong been built with checkpoints? ”

After contacting Yan Qing, Ning Yuan immediately expressed his intentions.

"Okay, boss, you go first, there will be news later, I'll call you." After Yan Qing understood what Ning Yuan meant, she immediately took action.

After about two hours, Ning Yuan's mobile phone rang suddenly, and after seeing that the caller's name was Yan Qing, Ning Yuan pressed the answer button for the first time.

"How? Any definite news? After the phone was connected, Ning Yuan asked eagerly.

"There's news, but this news should be bad news for you, boss.

According to several brothers who had been in the Hanzhong area, when Hanzhong was still in the hands of the player forces, in order to prevent the Yanyulou entrenched in the Chang'an area from attacking Hanzhong, the player forces in Hanzhong formed a Hanzhong Alliance.

Not only did they build easy-to-defend and hard-to-attack checkpoints on the passages leading to Hanzhong in several passes, but they also built at least three checkpoints on each pass.

In other words, if we want to attack Hanzhong, we must break through three levels in a row, otherwise we will not want to enter Hanzhong.

The brothers also said that not only was the passage between Hanzhong and Guanzhong built, but also the passage from Hanzhong to the Sichuan Basin was covered with a large number of checkpoints.

Most of those levels are built in places that are easy to defend and difficult to attack, and as long as a few thousand people are placed in the level, you can block the attack of tens of thousands of troops. ”

Yan Qing told Ning Yuan what she had heard.

After listening to Yan Qing's explanation, Ning Yuan didn't speak for a long time, and his face was very solemn.

"What's wrong? Boss, are you okay? Seeing that there was no movement on the other side of the phone, Yan Qing asked with concern.

"Nothing? Thinking about things and thinking about it.

Okay, thank you, brother, I'll call you again if there's something, I'll hang up first. Ning Yuan replied.

"Okay, goodbye, boss." Yan Qing heard that Ning Yuan didn't want to talk anymore, so she said goodbye directly.

After hanging up the phone, Ning Yuan lay directly on the sofa, looking at the ceiling, thinking hard about how to solve it.

What can be done to prevent the enemy from escaping back to Hanzhong?

Directly sending troops to break through to the Chang'an area, and then guarding the entrances to those passages, is the fastest way to achieve results.

However, the enemy is not stupid, and they will definitely send heavy troops to defend those entrances, so this solution will not work at all.

After thinking hard for a long time, Ning Yuan didn't come up with any good way, and in the end he only thought of a strategy to lure the enemy, that is, the Condor Army to defend, lure the demon army to take the initiative to attack, and then take the opportunity to severely damage the demon army that came to attack in one fell swoop.

Although this method cannot completely wipe out the demon army entrenched on the south bank of the Wei River, it can weaken the living force of the demon clan to the greatest extent.

As for how the Condor Army should attack Hanzhong after the remnants of the demon army withdrew to Hanzhong, it can only be seen step by step.

......

While Ning Yuan was pondering how to destroy the demon army, the players of the Northern Expedition Alliance were also in urgent negotiations.

After the Northern Expedition players who had defected to the demon army were abandoned by Daniels, it was difficult for them to get first-hand information from the front.

Just as they were about to ask some players to go to the Demon Clan at random and then go to the Guanzhong region to inquire about the news, a large number of corpses of demon warriors suddenly appeared in the Yellow River Valley in Luoyang.

After discovering that the raging waters of the Yellow River were filled with the corpses of demonic warriors, some of the top brass of the Northern Expedition Alliance immediately thought of a worst-case scenario.

These corpses all floated into the Yellow River from the Wei River, and there were only the corpses of demon warriors in it, and there were no corpses of other races, so many people instinctively thought that the demon army had been defeated.

After discovering that the demon army had been defeated, a group of players led by Ye Ziqing thought that it was time to immediately put in the tiger army of the Linhai Empire and let the tigers attack from behind the Condor army.

The leader of the warlord players represented by Li Yufeng believes that it is not yet the time, because a large number of checkpoints have been built on several passages leading from Guanzhong to Qinling, and even if the demon clan is defeated, it will still not be defeated to the end.

80,000 Terran hoplite legions, 40,000 dwarven hoplite legions, 10,000 hoplite cavalry legions, 40,000 terran light cavalry legions, 40,000 elven ranger legions, 10,000 dwarven cavalry legions, 90,000 barbarian legions, 60,000 Condor Guards, 10,000 orc hoplite legions, 100,000 werewolf guerrilla legions, 90,000 elven windrunner legions, and more than 500 dwarven ice bear knights, a total of 570,000 people.

Behind the Elephant Warriors are heavily armed Bear Warriors, Minotaur Warriors, Boar Warriors, and Tiger Warriors, and unlike the Elephant Warriors, these large men are armed directly to the teeth, and each one is like a small moving bunker, which will feel very difficult to gnaw just by looking at it.

Behind the orc hoplites is the 60,000 Condor Guards led by Shen Wanli, flanked by the Terran Heavy Infantry Legion, and behind the Terran Heavy Infantry Legion are the Dwarf Heavy Infantry Legion and the Barbarian Legion.

Behind the Condor were five hundred dwarven ice bear cavalry and the Terran heavy cavalry legion, the werewolf guerrilla legion and the elven windrunner legion followed behind them, and on the two wings were the Condor Leader's cavalry legions.
