A breeze blows through the southeast, and the already weak fire suddenly turns red again, making crackling sounds. Watermark advertising test. Watermark advertising test.

"Yeah~ah..."

Not far away, on the watchtower that was more than ten meters high, the soldiers on the night side were at their most sleepy moments. They stretched their waists tiredly, and could no longer open their eyes.

He looked at the model army in the southeast direction and there was nothing unusual. It was quiet everywhere, and he secretly looked around him.

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

Looking around, the whole world seems to have entered a state of peace and tranquility.

But if someone looks carefully, he will find-

In the wilderness several miles on both sides of the model army battle formation, there were several mud figures that were almost integrated with the land under their feet. Some seemed to be wearing straw hats, just like a group of dry land loaches, quietly approaching the camp of the Han army's Zhengbai Banner.

But at this time, the night was shining and the moonlight was faint. The positions chosen by these figures were extremely tricky. Unless they stared at a certain area for several minutes, it would be difficult to find something strange.

The model army fronted the front, behind the high earth wall.

Chunni looked at a few figures, which were gradually approaching more than a hundred steps before Shi Tingzhumen's troops, and her heart had already been raised to her throat, as if it was no longer her own.

Even though she had already made a lot of preparations, Chunni also had strong confidence in these model Junerlang, but at this moment, this scene was really...it was really too exciting. How could she face it calmly?

Seeing Chunni almost bit her tender red lips, Xu Changqing couldn't help but smile, gently stroked her slim waist, and said softly: "Don't panic, trust the men."

"Forehead……"

Chunni came to her senses and swallowed her saliva with her small breasts. She pretended to be indifferent: "I'm not panic. I'm just observing the Tartars."

Xu Changqing couldn't help but shake his head and laugh, too lazy to expose the girl's little thoughts, and his mind immediately gathered in front of him.

Even though he was extremely confident in the men of the Model Army, especially these men of the engineers, Xu Changqing was actually a little nervous.

Disguise and crawl forward can be said to be a compulsory course for model Junerlang, especially engineers, which are more strict in this regard. According to the nutritional conditions of this era, the tolerance rate is largely high.

After all, even a small-scale surprise attack like later generations was a frequent success and a very high success rate.

But there are always exceptions in everything.

Xu Changqing was really afraid that there would be some "mutants" under Shi Tingzhu's command, and there was a strong presence of vision and talent.

If this first step is discovered, even if it will not affect the overall situation tonight, it will be certain that it will take more trouble and casualties.

Fortunately, the Bajie Team quickly arrived under the first defensive earth wall of the Qing army, and did not attract the slightest awareness of the Qing army.

"call."

While Chunni breathed a sigh of relief, Xu Changqing also breathed a sigh of relief, but she forced herself to prevent this girl from seeing it.

Seeing that the first step was successful, the engineers and men had already started to make arrangements. Xu Changqing waved his hand to wave Wang Xi not far away, "I inform the hot air balloon troops and prepare to start!"

"yes."

Wang Xi had been waiting for a long time, and after a clever heart, he was busy quickly to send the order.

Soon, a large number of flashing "fireflies" quickly rose from the rear of the model army's battle formation.

These "fireflies" are grouped in three or five, which are quite scattered, but when you look closely, they seem to be quite organized.

Soon, they flew forward quickly along the southeast wind tonight.

After passing by the central 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 to sprint straight to the position of the Zhengbai Banner.

Xu Changqing thought that these Han army's Zhengbai Banners would definitely discover the operation of the hot air balloon troops as soon as possible and immediately start the next plan.

But what makes Xu Changqing speechless is...

Ten seconds, twenty seconds, one minute...

After a full minute and a half, the servant who had no nap in the battle formation of the Zhengbai Banner and whose eyes were sharp-eyed noticed the abnormality here, immediately exclaimed in a broken voice:

"Enemy attack, enemy attack! The hot air balloons from the model army are coming..."

Although these Han army's slaves from the Zhengbai Banner were quite generous by the Model Army's stability over the years, they were old-fashioned strong soldiers after all, and they reacted after a moment.

Suddenly, there was a sirens in the entire camp, and the whole camp was filled with chaos.

"Swoosh, swosh..."

However, not long after they had reacted, these dozen extremely fast light hot air balloons came to their formation and threw down unknown objects.

"boom!"

"Baola..."

After a while, these objects exploded one after another in the air, and even splashed with fierce flames, sometimes bringing out many black pieces of pottery that were originally model military crisp fish.

It is the unknown oils and fats in the model army battle formation.

However, in order to ensure the combustion power of these greases in the clay pots, some gunpowder was added to ensure that they were foolproof.

In the blink of an eye, many violent flames appeared on the outpost of the Han army's Zhengbai Banner, which shocked many servants cried and screamed, and they could not find the north for a while.

"What's going on?"

At this time, Shi Tingzhu of the Central Army rushed out anxiously, because he was too anxious and was not wearing any clothes in a straightforward manner, revealing a large cluster of black hair on his chest.

"Master, no, the model army has hot air balloons to steal the camp! Look at the back, there are many fires behind, and they seem to be coming to the real world!"

A personal guard slave hurriedly reported to Shi Tingzhu.

Shi Tingzhu saw for a while and saw at least hundreds of firelights behind him. He was shocked, but he couldn't stop sneering: "Hmph, Xu Changqing, this mischievous dog, I'm not that easy? I passed our military order, and everyone hid according to the scheduled plan, and only defended the front line position! I asked him to bomb and let him explode, and see how capable he was?"

As Shi Tingzhu's order was issued, many servants rushed forward, and the chaos in the battle formation of the Zhengbai Banner was slightly better.

The main reason is that the buildings inside them are all "ground nests" and a lot of live water has been introduced, and both air defense and fire protection capabilities are not weak.

But what they did not notice was that before their outpost battle formation, the engineers of the Model Army had already started their work.

Their working principle is not complicated. They use the cover of the hot air balloon above to go down to the trench of the Qing army, dig out several blasting holes, and stuff the explosive pack into it.

The trench on the outermost side of Zhengbai Banner was not brought in by living water, and it was only when it was obtained the second earth wall inside.

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

At this time, the Zhengbaiqi and other outpost slaves were suppressed by hot air balloons, and no one noticed this at all.

At this time, the main force of the model army's hot air balloon has arrived, like a dark cloud covering the sky and the sun, which soon covered the entire Zhengbai Banner outpost.

"boom!"

"Boom!"

In the blink of an eye, many terrifying bursts sounded in their positions, and the white flag servants dared not look up.

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

"snort."

When Shi Tingzhu saw this, he felt even more at ease and sneered: "I knew that Xu Changqing had fewer flowers. Now, it's true! I want to see how you are capable today!"

Just when Shi Tingzhu Zhi was proud and ready to take advantage of this opportunity to make a name for himself and exclaim his anger.

Before their outpost, the engineers had already issued

Come and prepare the signal.

How could Xu Changqing hesitate? With a wave of his hand, the passionate swan sound of "wow and whimper" immediately rang through the night sky.

At once, at least seven or eight thousand agile model Junerlang quickly rushed out of the battle formation and approached the Zhengbai Banner position, but the many explosive packs of the Zhengbai Banner outpost position were not in a hurry to detonate.

"Hey!"

"Who are you scaring me? You guys dare to come into my battle formation. Let's see how I deal with you!"

Seeing that the model army had actually sent so many main forces rashly, Shi Tingzhu's sneer couldn't help but lick his lips bloodthirsty.

In just seven or eight minutes, the main force of the Model Army had already approached the Zhengbai Banner outpost position, and the hot air balloon had completely wrapped their entire position.

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

fine.

It's okay.

The first target of the Model Army is not them, otherwise who else can I ask for reason?

Fortunately, the food and grass of Shitingzhumen were all in the cellar, and they also put in full force and made sufficient fortifications. They were not too afraid of the bombing of the Model Army. Ma Guangyuan and Zu Zerun also wanted to have a good look at what the Model Army wanted to play tonight.

"Boom!"

"Boom!"

Just as the situation of the battle formation was a little stagnant and the model army's propulsion fortifications obviously did not have too many auxiliary soldiers to fill the soil, a terrifying explosion suddenly came from the outpost of Zhengbai Banner. It was as if the earth was shaking, and it was shocked by continuous palpitations.

This enhanced explosive package designed specifically for bombing buildings and city walls is obviously not comparable to ordinary flowering bullets.

Immediately, just as accurate as a computer calculation, the eight-legged model military engineer squad collapsed in the trench on a large scale.

Even if it is blown up like this, it is not too flat, and there is still a lot of gaps. However, compared to the trench several meters deep, this height saves a lot of effort. Just filling a few sandbags can be like flat ground.

"Bird gun soldiers cover, spear soldiers, prepare to advance!"

"Brothers, follow closely, don't fall behind!"
