A breeze blew from the southeast, and the fire, which was already a little weak, suddenly turned a lot redder and crackled.

"Hmm~ah......"

Not far away, on the watchtower more than ten meters high, the soldiers on duty at night were also at their most sleepy, stretching tiredly, and their eyes could not be opened.

Looking at the model army in the southeast direction, there was nothing abnormal, there was silence all around, and he secretly looked around under him.

Seeing that the patrol had already passed, he slowly lowered the brim of his hat, leaned against the root of the wooden fence behind him, and snuckly took a nap.

As far as the eye can see, the whole world seems to have entered a peaceful state of harmony.

It's just that if someone looks closely, they will find that-

In the wilderness within a few miles on both sides of the model army's battle array, there were several muddy figures that almost merged with the ground under their feet, some of them seemed to be wearing straw hats, just like a group of dryland loaches, quietly approaching the camp of the Han army with the white flag.

But at this time, the night is dark, the moonlight is faint, and the positions chosen by these figures are extremely tricky, unless they are staring at a certain area for a few minutes in a row, it is difficult to find anything unusual.

The model army is in front, behind a high earthen wall.

Chunni looked at a few figures, and they were gradually approaching more than a hundred steps before Shi Tingzhu's department, and Fang Xin had already mentioned it in her throat, as if she no longer belonged to herself.

Rao has already made a lot of preparations, and Chunni also has strong confidence in these model soldiers, but at this time, this scene is really ...... It's really a little too exciting, how can she face it calmly?

Seeing that Chunni almost bit her delicate red lips, Xu Changqing couldn't help but smile, gently stroked her little waist, and said softly: "Don't panic, you have to trust the children." ”

"Forehead ......"

Chunni came back to her senses, swallowed her saliva dryly, and pretended to be indifferent with her small chest: "I didn't panic." I'm just looking at the tartars. ”

Xu Changqing couldn't help but shake his head and laugh, and he didn't bother to poke the girl's careful thoughts, and his mind immediately converged to the front.

Even though he had great confidence in the sons and daughters of the model army, especially these sapper soldiers, Xu Changqing was actually a little apprehensive in his heart.

Camouflage and creeping forward can be said to be a compulsory course for model soldiers, especially sappers, who are more strict in this regard, and according to the nutritional conditions of this era, the error tolerance rate is still very high to a large extent.

After all, even this kind of small-scale surprise attack in later generations is also a frequent success, and the success rate is extremely high.

But there are always exceptions.

Xu Changqing was really afraid that there would be any 'mutants' under Shi Tingzhu's command, and there was an existence with super eyesight talent.

If this first step is discovered, even if it will not affect the overall situation tonight, it will definitely take a little more twists and turns.

Fortunately, the eight detachments soon arrived under the first defensive earthen wall of the Qing army, without attracting the slightest notice from the Qing army.

"Whew."

While Chunni breathed a sigh of relief, Xu Changqing also breathed a sigh of relief in her heart, but she couldn't hold back and didn't let this girl see it.

Seeing that the first step was successful, the sappers had already begun to arrange, Xu Changqing waved his hand and beckoned Wang Xi who was not far away, "Inform the hot air balloon troops, get ready to start!" ”

"Yes."

Wang Xi had been waiting for a long time, and a clever queen was busy quickly going to give orders.

Not long after, from the rear of the model army's battle array, a large number of flickering 'fireflies' soon rose.

These 'fireflies' are scattered in groups of three or five, but if you look closely, they seem to be quite orderly.

Soon, they were flying forward with the southeast wind tonight.

After passing the position of the model army, more than a dozen colorful hot air balloons gradually showed their prototypes, just like the elves of the dark night, speeding up and sweeping directly at the position of the White Flag Department.

Xu Changqing thought that this group of Han soldiers would definitely discover the actions of the hot air balloon troops as soon as possible and immediately start the next plan.

But what made Xu Changqing speechless was......

Ten seconds, twenty seconds, one minute......

A full minute and a half later, there was a non-napping and sharp-eyed minion in the battle formation of the White Banner Department, and when he discovered the abnormality here, he exclaimed in a voice like a broken gong:

"Enemy attack, enemy attack! The hot air balloon with the model army is coming......"

Although these minions of the Han Army with the white flag have been relatively supported by the stability of the model army these days, they are old and strong after all, and they reacted after a while.

Suddenly, the entire camp was called for alarms, and chickens and dogs jumped.

"Whoosh, whoosh, whoosh......"

However, not long after they reacted, more than a dozen light hot air balloons with extremely fast speed came to their formation and dropped unknown objects one after another.

"Boom!"

"Pop ......"

A moment later, these objects exploded in small bursts in the air, splashing in clusters of fierce fire, and sometimes carrying with them many black shards of pottery that were originally used to hold model military crisp fish.

It's the unknown grease of the model army.

It's just that the grease contained in the clay pot, in order to ensure its combustion, a part of gunpowder is specially added, just to be foolproof.

In the blink of an eye, there were many tyrannical fires in the outpost position of the White Banner Department of the Han Army, and many startled minions were crying and screaming, and they couldn't find the north for a while.

"Dog offal, what's going on?!"

At this time, Shi Tingzhu of the Chinese army also rushed out in a hurry, because he was too anxious to wear clothes, revealing a large dense black mass on his chest. Hair.

"Master, it's not good, the model army has a hot air balloon to steal the camp! Look at the back, there are still a lot of fires in the back, they seem to be coming for real! ”

There were guards and servants who hurriedly reported to Shi Tingzhu.

Shi Tingzhu looked at it for a moment and saw clearly that there were at least hundreds of fires behind him, and he was taken aback, but he couldn't stop sneering: "Hmph, Xu Changqing, this dog is a miscellaneous dog who wants to yin Laozi, how can it be so easy?" Pass on my military order, everyone will hide according to the predetermined plan, and only defend the frontline positions! Lao Tzu let him bang, let him blow up, see if he can withstand Lao Tzu? ”

As Shi Tingzhu's order was issued, many herald servants rushed forward, and the chaos in the battle formation of the White Flag Department was slightly better.

The main reason is that the buildings inside them are all 'underground nests', and a lot of living water has been introduced, and the air defense and fire prevention capabilities are not weak.

But what they didn't notice was that at this time, before their outpost battle formation, the engineer sons and daughters of the Model Army had already begun their work.

Their working principle is not complicated, using the cover of the hot air balloon above, they went down to the trenches of the Qing army, dug out several blasting holes, and stuffed the explosives bag into it.

The outermost ditch of the White Flag was not brought in by living water, and it was only when the second earthen wall inside was obtained.

This way, as long as the angle is correct, a little digging below can ensure that the earthen wall falls directly into the trench, thus saving a lot of effort to push the earth.

At this time, the outpost minions of the White Flag were all suppressed by the hot air balloon, and no one noticed this at all.

And at this time, the main force of the model army's hot air balloon also arrived, like a dark cloud covering the sky, and soon the entire Zhengbai Flag outpost position was enveloped.

"Boom!"

"Boom!"

In the blink of an eye, many terrifying crackling sounds sounded in their positions, and the white flag minions didn't dare to raise their heads.

But if you listen carefully, you will find that the offensive of the model army seems to be fierce, but in fact, the real density is not high, but it is a bit sparse, like a poor family reluctant to let go.

"Hmph."

When Shi Tingzhu saw this, his heart couldn't help but be more steady, and he sneered: "I know that Xu Changqing's dog is not much of a flowering bullet, now look at it, it is really so!" Lao Tzu wants to see how you can endure Lao Tzu today! ”

Just when Shi Tingzhu was full of ambition and was ready to use this opportunity to make a name for himself and let out a bad breath in his heart.

Before their outpost, the sappers had already sent out

to prepare the right signals.

How could Xu Changqing hesitate? With a wave of his big hand, the rousing swan sound of 'woo woo' immediately resounded in the night sky.

At that time, at least seven or eight thousand vigorous model soldiers quickly rushed out of the battle formation and approached the Zhengbai Banner position, but the many explosive packages in the Zhengbai Banner outpost did not detonate in a hurry.

"Hey!"

"Who are you scaring about, you dogs dare to come into Lao Tzu's battle array, see how Lao Tzu cleans you up!"

Seeing that the Model Army had dispatched so many main forces so rashly, Shi Tingzhu's sneer couldn't help but be even worse, and he licked his lips bloodthirsty.

In just seven or eight minutes, the main force of the Model Army was already approaching the outpost of the White Flag, and the hot air balloon had completely enveloped their entire position.

This also made Ma Guangyuan and Zu Zerun, who were not far away, look straight necks.

OK.

It's fine.

The first target of the Model Army is not them, otherwise who would be reasonable?

Fortunately, the grain and grass in Shi Tingzhu's department are in the cellar, and they have also put in a lot of strength and done enough fortifications, not too afraid of the bombing of the model army, Ma Guangyuan and Zu Zerun also want to take a good look at how the model army wants to play tonight.

"Boom!"

"Boom!"

Just when the situation in the battle array was a little stagnant, and the advance fortifications of the Model Army obviously did not have too many auxiliaries to fill in the earth, the sound of a terrifying explosion suddenly came from the outpost of the White Flag, and it was as if the ground was shaking like a mountain, and the screams of continuous heart palpitations were aroused.

This enhanced version of the explosive pack, which is specially designed to blow up buildings and city walls, is obviously not comparable to ordinary flowering bombs.

Immediately, as accurate as the computer had calculated, eight units of model military engineer squads, eight earthen walls, collapsed in a large area in the trench.

Rao is not too flat to blow it up like this, and there are still a lot of drops, but compared to a trench several meters deep, this height is already a lot of effort, just fill a few sandbags can be like flat ground.

"Birdmen cover, pikemen, prepare to rush!"

"Brothers, keep up, don't be left behind!"

With the erection of the eight fulcrums, how could the sons and daughters of the model army hesitate, and instantly rushed to the battle formation of the white flag like a wolf, followed by the sound of 'bang bang bang' birds.

Pity these minions with white flags haven't reacted much, what is going on, they are already suppressed in the dirt nest and can't get out.

Anyone who dared to come out and escape was killed by the model army at the first time.

However, after the model army took control of the situation in the outpost battle array, it did not continue to move forward, nor did it rashly clear the minions in the nest, but quickly adjusted on the spot, not knowing what they were doing.

Shi Tingzhu had been suppressed by the hot air balloon in the sky at this time, so he didn't dare to raise his head, so he could only take off his helmet and let his handsome flag be erected outside the earthen nest on the other side of the Chinese army, which caused the model army hot air balloon to bomb continuously, and then he secretly climbed to the lookout from the other side to check the situation.

As soon as they saw that the Model Army had actually rushed into their outpost, they stopped again, not knowing what they were busy with.

Shi Tingzhu was clever when he landed, and he already realized that something was wrong.

But at this time, he definitely can't run yet, you must know that 'losing the land' is a felony of stealing the family and exterminating the clan, plus so many hot air balloons, running out will undoubtedly become a live target for the model army.

His eyes rolled, and he hurriedly beckoned to the guards and servants around him: "Quickly find a place to send signal flares and ask for help from the Lord!" ”

"Wow!"

Seeing that this guard slave was busy with his work, Shi Tingzhu already had a case in his heart, and if he held on for a while, it almost meant that even if he didn't run away directly, he had to retreat to the back of the formation.

If there is really any big fluctuation, he will run away as soon as possible, and the master will not blame him.

But as soon as he climbed to the lookout at the back, trying to see the situation and think about what to do, he was dumbfounded.

I saw that the passages behind their camp were all wrapped in raging flames.
