Brest.

Jian Xiao reached Brest at a speed far beyond Zhu Sanfeng's expectations, but he did not manage to break through Brest, but was stationed in the mountains and forests south of Brest.

"General Qian! The news of the king's envoy has not yet arrived! ”

"Got it, let's find out." Jane replied with a smile without raising her head.

"Yes!"

……

With the herald leaving, Jane Xiao's tent was quiet again, but it didn't last long.

For two days, two whole days, the scouts roamed non-stop on the border between Brest and Masovia, trying to get news of the troops led by Wang Jinghong.

The non-stop spying means that the number of messages sent back is also quite large.

In the past two days, Jian Xiao has not slept a bit, because the scout's report is once an hour, which is set by Jian Xiao.

Whether you get the news or not, you have to report it once an hour, because the scout is not just the news from Wang Jinghong's side.

There is also news of Grodno, the first line of defense in the west of Vilno, the capital of the Grand Duchy of Lithuania.

"Report!"

Unlike usual, the herald who reported the news last time had just left, and this Jane Xiao's voice sounded again after listening to it for two days.

"Enter!"

"General Qian! The Mu family in Suez sent a batch of supplies! It is said that it is personally arranged by His Royal Highness the Prince of the World, and you need to receive it personally! ”

"Huh?" Jane looked up with a smile in surprise, then tugged around the table for a while to find a simplified version of the calendar that had been pressed to the bottom.

"Five days ahead of the next supply?"

Jian Xiao was puzzled, but she still stood up and walked out of the tent.

Outside the gate of the camp, Mu Ang had already dismounted, and when Jian Xiao saw him, he was tiptoeing towards the camp.

When he saw Jane's smile, a smile appeared on Mu Ang's face.

"General Jane."

"Commander Mu knows the same thing."

When the two met, they first said hello to each other, and then stood still, Mu Ang took out a letter from his arms, and handed it to Jian Xiao after confirming that the fire paint on it was intact.

"This is a batch of supplies from Xiangzhou Mansion, I originally planned to send them to His Royal Highness the Prince, but when I stopped and waited in Venice, I received an order from His Royal Highness the Prince, saying that it would be divided into two parts, and one of them would be sent to you."

"This is a letter from His Royal Highness the Prince, saying that you must see it in person before you can receive this batch of supplies."

Hearing this, Jian Xiao took the secret letter from Mu Ang's hand, and took the time to glance at the batch of materials when he opened the envelope.

They were all covered with tarpaulins, and nothing could be seen.

Without getting any information from the appearance of the materials, Jian Xiao looked down at the secret letter in his hand.

In fact, there is not much content in the secret letter, just four lines, Jian Xiao quickly read it, and then took out his seal from his waist and stamped it on the letter paper in Mu Ang's hand.

This is to be sent to Junbao, because the current Junbao is equivalent to the last retreat of the Ming army in Europe, and it is a relatively safe existence.

For example, the materials transported by Mu Ang this time had to be stamped by both parties, and then sent to Junbao for backup and storage.

"There's General Lao Jian." Seeing that the seal had been stamped, Mu Ang carefully confirmed it before putting it away, bowing to Jian Xiao and arching his hand.

"I still have a task in the future, so I won't stay long, please forgive General Qian."

"Commander Mu knows the same way, be careful all the way." Jian Xiao didn't have any questions, and she didn't leave Mu Ang, but just bowed slightly to see Mu Ang off.

It wasn't until she watched Mu Ang's logistics force disappear from sight that Jian Xiao threw the letter in her hand into the brazier with the envelope.

"Someone! Send these supplies to the back! ”

"Remember! Be sure to store it separately, away from crowds and tents, and not with gunpowder white phosphores! ”

"Yes!"

……

After watching the soldiers properly store the supplies, Jian Xiao breathed a sigh of relief.

There is no other reason, what Mu Ang sent this time was actually a batch of weapons.

Not swords and spears, not artillery guns, not the white phosphorous eggs that are most used in European theaters today, but a new weapon.

Fire oil bombs.

This name made Jian Xiao feel very unfamiliar, he was sure that the Ming army had never used this weapon before, and he had never even heard of it, but in that handwritten letter, Zhu Zhan Yan told Jian Xiao about the use of this weapon, its characteristics, and storage.

Like the White Phosphor, this fire bomb is also a type of fire attack, and when exploded, it will also burst into flames, and will also attach to any living creature or object until it burns out.

Does that sound familiar?

That's right, the oil bomb is just a random name given by Zhu Zhanyan, just to fit this era, and in later generations, the name of this thing is napalm egg (also for anti-river crabs).

In fact, he hadn't taken out this fire oil bomb before, not because Zhu Zhanyan didn't know how to do it, let alone because Zhu Zhanyan was kind.

The white phosphorous egg is actually much more cruel than this thing, and the burn is not weaker than that of a fire oil bomb, and it is also poisonous.

The reason why it has not been taken out until now is mainly because of the word coagulation in this napalm egg.

If there is no viscous agent, the oil bomb produces a gelatinous accelerant, then it is the same as pouring gasoline on the fire, and there is no adhesion.

It's not that Zhu Zhanyan can't make this thing of viscous, but it can't be made on a large scale due to the limited conditions before, and this thing is not as easy to mass produce as white phosphor eggs in comparison.

In order to build a steam engine, Zhu Zhanyan asked Qian Yong and others to go to South America to take risks to retrieve the seeds of rubber trees, and later made natural rubber to make sealing rings, and let people go whaling to obtain whale oil as an industrial lubricant.

It can be regarded as intentionally planting flowers and flowers, and unintentionally planting willows and willows.

At first, when Zhu Zhanyan wanted to engage in napalm eggs, he chose to give up because of the problem of viscous, and later forgot about it when he was engaged in rubber trees and whale oil, and later because the white phosphorus storage in Xiangzhou Mansion was consumed too much, which made Zhu Zhanyan think of this thing again.

Napalm eggs are actually not difficult to do, but the hard thing to do is nitric acid, because this thing is needed in the viscous agent of napalm eggs.

The three acids and two alkalis, which are the basis of the chemical edifice, are not so simple to produce in large quantities in this era, but it is still possible to produce them in small quantities.

The easiest way is to calcine saltpeter, and then add water and oxygen to produce nitric acid in small amounts.

But the nitric acid produced in this way was not enough for Zhu Zhanyan to use, so he thought of another way.

He learned how Eagle Sauce used to make a foot basin, adding a small amount of sugar and a small amount of calcium powder to the viscous agent and gasoline to complete the advanced version of the oil bomb.

White sugar is actually a strategic material, which can increase the burning energy of the oil bomb, and the calcium powder is to prevent the enemy from entering the water to extinguish the fire when encountering the oil bomb, because the calcium powder can react with the water and instantly burn through your brain.

In this way, Zhu Zhan Yan was able to produce a large number of fire oil bombs under the premise that the viscous agent could not be produced in large quantities.

However, this is only a stopgap measure, in terms of the difficulty of making, it is still easier to make white phosphorous eggs, and the current fire oil bomb is just to reduce the consumption of white phosphorous eggs.

However, this is enough to make Jian Xiao feel at ease.

"Someone."

After pondering for a long time, Jian Xiao finally gave the order after overcoming the hesitation caused by the lack of firepower.

"Tomorrow morning, make dinner at the right time, set off at the end of the day, and the goal is ......"

"Black Rus Territory!"

……

As night fell, Brest fell silent, and the fire flickered above the city, as it had been since the arrival of the Ming army.

The continuous high-intensity patrols and nervous emotions kept the soldiers in Brest in a state of high tension, so much so that they are now a little mentally exhausted.

At about 11 o'clock in the middle of the night, a large number of Ming troops came out of the mountains and forests, and all artillery and other weapons were transported out of the mountains and forests on the premise of keeping enough quiet.

Why is it 11 o'clock in the middle of the night?

In fact, in the European campaign, there has always been a problem of time difference, Jian Xiao and others do not understand this problem, and they still calculate it according to the time of the Ming Dynasty.

As for the question of why they have been able to keep the time of Daming, the reason is that Daming commonly used timekeeping tools.

In addition to the sundial, a timekeeping tool commonly used in the Ming Dynasty is called leaky carving, also called leaky pot, the principle is that there are two copper kettles up and down, and small holes are opened in the copper kettle above to ensure that the water inside drips evenly, so as to determine the time.

Now in Brest, there is a time difference of about six hours with Shuntianfu, that is, three hours, which means that Jian Xiaoyin's decision to make rice at the time of cooking and leaving at the time of Mao should also be pushed forward by three hours, and it will be pushed forward to the time when the meal is made and the time is ugly.

It's a serious night attack.

It was the most sleepy time for mankind, and the soldiers of Brest had been highly nervous after receiving the news of the Ming army's presence here, and their vigilance was even worse after midnight.

Woo~~~

The low sound of the horn suddenly sounded, which suddenly woke the soldiers at the head of Brest City, and the sleepiness disappeared without a trace in an instant.

However, when the horn sounds, it means that the offensive has begun, and it is only at this time that you are awake...... It's too late.

Sneer......

A series of sharp and piercing sounds sounded, and a swarm of bee rockets pierced the night sky and flew in the direction of Brest, and the light of the fire dragged behind instantly lit up the sky.

"Ready!"

At the moment when a large swarm of rockets was used to light up the sky, Jian Xiao immediately gave an order, allowing the soldiers operating the artillery to take this opportunity to adjust the direction and height of the artillery.

"Put!"

As a swarm of rockets fell into the city of Brest, the soldiers operating the artillery had a goal, and Jian Xiao immediately gave a second order.

Bang! Bang! Bang!

A series of artillery shots rang out, and a slightly inconspicuous white smoke in the dark night flew towards Brest with a sparkling light of indecipherable fire.

One...... Two...... Three...... Four......

Jane stared at the direction of Brest with a smile, silently counting in her heart, and even his heart was sweating at this time.

It's not that he doesn't believe Zhu Zhanyan, but directly trying out a new weapon on the battlefield will make people feel more or less uneasy.

But fortunately, Zhu Zhanyan has never been a "Mr. Almost".

Without any warning, without any sound, and even without feeling anything, Brest, about three hundred paces away, suddenly erupted into a burst of intense firelight, illuminating almost half of Brest.

The light of the fire did not disappear in the wind, but grew stronger and stronger as time passed, and even illuminated the face of Jane Xiao, who was three hundred paces away.

Looking at the distant firelight, Jane Xiao's eyes were shining, but they were not tears, but the reflection of the extremely watery eyeballs under the only light in the dark night.

"A swarm of rockets retreated, and the artillery was ready for the second round!"

After seeing how effective the new weapon was, Jian Xiao immediately removed the swarm of rockets that had been prepared for the second round, and directly asked the artillery to prepare to fire again.

With the white phosphor egg and this oil bomb, Jian Xiao seemed to have seen the kings of various European countries trembling.
