August 3, Shaguan.

At this moment, it was the third night of the Iron Elephant siege, and Shangguan Invincible stood on top of the towering watchtower, looking at the sparks below, his brows furrowed.

After three consecutive days of siege, the Iron Elephant Dynasty has left 100,000 lives, plus the disabled, the total casualties must be 150,000!

Dasheng, on the other hand, lost less than 20,000 casualties, and less than 30,000 wounded.

Shangguan Invincible had always been a little puzzled before, what kind of calculation the other party was playing.

Even if you want to fill it with human life, if you go on like this, you can't fill it at all!

Until today, when the sun was setting in the west, I happened to hear a few formation mages talking about the slow repair of formations;

He struck a fierce spirit and remembered a word - "Ming Xiu Plank Road, Dark Chen Cang"!

At dusk on the first day of Shaguan, all formations were launched, although tens of thousands of enemy troops were successfully destroyed;

But the price is that the metacrystals are exhausted, and many formation nodes are destroyed by the enemy!

However, it takes a lot of time to repair and replenish the Yuan Crystal, so that within a few days, the protection of the sand pass will be greatly reduced.

However, the most important thing is the failure of an auxiliary formation - the early warning formation!

The early warning formation can not only roughly perceive the strength, direction, and number of the enemy, but also issue a warning when someone sets foot in some key places.

Previously, due to the existence of an early warning formation, it was able to warn the depth of more than ten zhang underground in Shaguan, but everyone subconsciously ignored this point.

But now that all formations have failed, and the early warning formations are no exception, will the enemy dig tunnels and kill in?

Shangguan Wushu was deeply worried about this, but he couldn't think of how to verify the conjecture.

Fortunately, Su Rongrong thought of a clever trick, she proposed to select some key parts to dig small deep holes below;

Then fill the deep cave with water, and observe the fluctuations of the water to determine whether the other party is carrying out a plot to dig a tunnel.

Because distant vibrations can travel far away in a similar plane, it is completely feasible to do so.

After that, Shangguan Invincible asked Su Rongrong and others to mobilize a group of soldiers to take charge of this matter, but unfortunately there was still no news until now.

After another two or three quarters of an hour, suddenly there was an excited shout from behind.

Shangguan Invincible looked back, but it was Lu Qing who was a little disgraced.

"My lord! The enemy is indeed digging deep into the tunnel!"

Shangguan Invincible's eyes suddenly lit up, and he asked eagerly:

"Are you sure?"

"Go back, sir, sure! Miss Su asked me to dig hundreds of deep holes in different directions;

Most of the water in these deep caves is fluctuating violently or slightly, so you can't go wrong!

In addition, according to the strength of the fluctuation, Miss Su believes that the enemy army should dig in three ways at the same time!

Moreover, it seems that two of these three roads have already exceeded the position we are at this time, and they are already close to the second wall!"

Shangguan Invincible couldn't help but clench his fists fiercely.

"Well!

Seeing the enemy's actions like this, I'm afraid that they want to take down three walls at the same time!

In this way, you can tell Ah Rong and ask her to find a way to determine the approximate exit location of the enemy tunnel!

Ben Ya is going to look for General Zhenxi!"

"No!"

Shangguan Invincible was walking towards the first wall, and he kept thinking about it.

He couldn't figure out the meaning of the other party's arrangement.

Since the other party has already sent a surprise soldier to Baisong Mountain, why do they have to dig tunnels so hard?

You must know that the price of the other party's painstaking efforts to make the Shaguan formation ineffective is the slaughter of fifty or sixty thousand troops!

After thinking about it for a long time, he still couldn't think of a reason, so Shangguan Invincible had to shake his head helplessly and ignore it for the time being.

The first wall, the united front platform.

Dongfang Li frowned and looked at the sand table in front of him, the battle situation in front of him actually gave him the illusion that he was in a fog.

Although after three days of fighting, it can be said that his side has the upper hand.

But because of this, he felt a little uneasy.

The Iron Elephant Dynasty's Xiang Yuanbo and Lan Yangxu are not easy people, would they be stupid enough to waste troops in such vain?

Could it be that there is some conspiracy?

But what is the conspiracy?

Dongfang Li raised his eyes and looked at the strategists and long history of as many as seven or eight people around him, and his eyes couldn't help but flash a look of dissatisfaction.

These guys are really useless, and they can't even bring up a decent question or strategy.

When he caught a glimpse of a person in the corner of his eye, Dongfang Li's heart suddenly moved.

"Wang He, what do you think about the current battle situation?"

Wang He was stunned for a moment, although Jin Yiwei successfully helped him step into the sight of General Zhenxi and was promoted to serve on his side.

But after all, he was only a small lieutenant, and he was not qualified to speak in such an occasion.

Now General Zhenxi actually asked him in person, which immediately surprised him.

"Your Excellency, I think this battle is too easy!

The enemy must have a conspiracy in it!"

Changshi Geng Xingwen suddenly sneered when he heard this.

"Nonsense! Everyone can see that something is wrong, and the general doesn't want to listen to your nonsense!"

Dongfang Li frowned slightly, and glanced at Geng Xingwen unhappily.

Geng Xingwen's back suddenly cooled, and he coughed dryly, but he lowered his head and didn't dare to speak again.

Wang He's face was a little unnatural, but after thinking for a while, he still said what he thought in his heart.

"General, I think that the enemy army is likely to dig a tunnel and infiltrate it!"

Tunnel?

The surrounding generals were stunned for a moment, and no one said anything to refute while looking at each other.

Because it was only then that they remembered one of the consequences of the complete failure of the formation......

Dongfang couldn't help but narrow his eyes, and when he was about to ask carefully, a figure suddenly walked in.

"He is right! The enemy is indeed making this calculation!

And it's digging three secret passages at the same time!"

Dongfang Li's face changed slightly, and before the other party stepped in, he had already known through his divine sense that he was Shangguan Invincible.

But he didn't expect to hear such an astonishing news.

"Shangguan Baihu, how did you know?"

Shangguan Invincible smiled and said:

"Didn't the general forget that Ben Ya had seconded some soldiers earlier?

As for the specific process, the situation is urgent, so I won't talk about it for now.

The most important thing now is to arrange the preparations for the closure of the wall immediately!

Since the enemy has dug the tunnel into the pass, the time for the general attack is not far away, and the most likely is after the early morning!

At this point in time, not only are our soldiers the most scarce, but when the enemy army comes out of the tunnel, it can also create chaos to the greatest extent!

In addition, General Zhenxi should immediately arrange the garrison of the second and third barriers, and dispatch elites to block the three tunnel exits!

If you could, you'd better drown them in the tunnels!"

Dongfang Li's expression suddenly turned grim.

"What Shangguan Baihu said is very true!

"In!"

"Immediately order all the Shaguan troops to enter a state of readiness!

"In addition, order the guerrilla general Kuai Yufeng to guard the second wall! Staff General Su Zhengqing to guard the third wall!

At the same time, he ordered Feng Hai to lead his elite to listen to the dispatch of Shangguan Baihu and destroy the enemy who infiltrated!"

"No!"

After everyone was ordered to retreat one after another, Dongfang Li looked at Shangguan invincible in a complicated way.

"Shangguan Baihu Zhiluo is so extraordinary, why not join the army?"

Shangguan Invincible shook his head with a light smile and said:

"General Zhenxi's reputation is overblown, and it's all the credit of his subordinates. As for the marching army, this is not the ambition of the next one. ”

Dongfang raised his eyebrows noncommittally and muttered, "It's a pity!"

......

On August 4th, it was ugly in the early morning (02:00).

Outside the Shaguan, the former camp of the Iron Elephant Dynasty.

"Marshal, almost. ”

Lan Yangxu glanced at the missing moment, and then hugged Xiang Yuanbo with his fist.

Xiang Yuanbo nodded, and then shouted at the generals and messengers in the account:

Except for the 50,000 troops left by the Chinese army to defend the base camp, the rest of the troops will attack the city with all their strength in a quarter of an hour according to the plan!"

"No!"

......

In the dead silence of the starless moon, countless black shadows like locusts quietly swarmed from the west to the black shadows like giant beasts.

However, before these black shadows could touch the foot of the wall, countless torches suddenly rose from the top of the wall!

This heaven and earth were reflected in an instant!

Then, in the earth-shattering shouts of killing, dense rockets and arrows shot down;

At the same time, there were also fire bombs that were frantically smashed by trebuchets and machine guns into the farther crowd.

However, after more than 100 breaths, it has turned into a human purgatory under the wall!

The flaming soldiers screamed and crawled wildly, knocking down the robes that they couldn't hide.

The tall siege equipment was even more focused on, and one after another was burned in the surging flames and thick smoke.

Lan Yangxu looked at this tragic scene in a daze, and his mouth couldn't help but feel a little dry.

But soon he came back to his senses and shouted at Xiang Yuanbo:

"Marshal, give the order to retreat!

The enemy army is like this, obviously it has been prepared for a long time!

There may be a master in Guanzhong, I'm afraid the tunnel has been exposed!

If you don't withdraw, it's too late!"

Xiang Yuanbo pushed Lan Yangxu away violently, his eyes glowing with rich blood red.

"No! It's not so easy to withdraw if you want to withdraw at this time! What's more, how can my tens of thousands of troops die miserably in vain?!

Therefore, we must not withdraw! We must go up with all our might!

Otherwise, there will be no chance to win this sand pass!

What's more, the tunnels are extremely secret, and the enemy may not be able to find out!"

Lan Yangxu's face suddenly changed greatly.

"Marshal, no! It's not too late for a gentleman to take revenge for ten years!

You can't be impulsive!"

"Impulsive?!Hmph! Ben Shuai has never suffered such a big loss!

If you don't take this sand pass today, Ben Shuai will not give up!"

Xiang Yuanbo's eyes were full of anger and hatred, but he refused to pay attention to Lan Yangxu at all.

"Someone! Order the whole army to kill Ben Shuai!

Those who dare to take half a step back, the team can be immediately killed!

The personal guards are assembled, and the commander will personally kill the head of the city and destroy the Dongfang Li!"

"No!"

"Marshal, don't be impulsive!"

Lan Yangxu hurriedly chased the general out, but he still couldn't dissuade Xiang Yuanbo from turning back.

"Alas, you're confused!"

Lan Yangxu hated that iron could not become steel, and stomped his feet fiercely, but he had no idea for a while.
