Separated from Liu Lang, Xu Changqing came to the south gate area of Ningyuan, turned a few alleys, and came to an inconspicuous dilapidated house.

This house looks dilapidated from the outside, there is no popularity, and there is a lot of wild grass, but as soon as you enter, you find that there is a lot of space inside, and there is a cave.

At this time, several large firewood-like things had been piled up in the corner of the courtyard, all of which were tightly wrapped in tarpaulin.

In the middle of the courtyard, a simple but very precise 'workshop' is erected with cloth and wooden frames!

Inside, several old craftsmen were taking more than a dozen apprentices with quick hands and feet, carefully making something, and they didn't notice it when Xu Changqing came over.

Waiting for Xu Changqing to cough lightly, everyone reacted, and they fell to their knees one after another, "General, you are here." ”

There were two people at the head, one was a white-haired old man in his fifties, named Zhang Jiu, who was an expert in gunpowder, and the other was younger, probably in his thirties and less than forty, not tall but very strong, and an experienced carpenter named Li Zhu.

They have been in Ningyuan City for more than ten days, which is the most critical link in Xu Changqing's layout!

"Hehe, they are all their own brothers, no need to be polite, Ninth Master, Lao Li, how is the situation?" Xu Changqing looked at the two with a smile.

Zhang Jiuye hurriedly said respectfully: "General, we have prepared more than 1,000 catties of gunpowder these days, but there is no place to experiment, and we can't accurately determine the effect......

As he spoke, he was a little ashamed and lowered his head.

After all, Xu Changqing gave them such a high salary, and each of them was given a settling-in allowance of five taels of silver, but they didn't produce any good results at this time.

Xu Changqing smiled: "It's okay." The main thing is to provide such an idea first. Later today, we'll be able to get out of town, and when we get back to Shark Island, you'll have a chance to experiment!" ”

Seeing that Xu Changqing's expression didn't seem to be fake, Zhang Jiuye was a little relieved and relaxed.

Xu Changqing looked at Li Zhu again.

Li Zhu was much more energetic than Zhang Jiuye, and said respectfully: "General, the carpentry is much smoother, these days we have received more than fifty good beef tendons through the relationship between Li Changyou and Li Ye, all of which have been pickled by me in secret methods for five or six days, as long as there is a day or two of drying time, you can directly make trebuchets at any time!" ”

Xu Changqing's spirits were also perked, and he nodded with a smile: "Very good!" The big war is coming, you are all hard, I won't say much if you have anything extra, you must work hard as soon as possible when you return to the island, and strive to complete the task as soon as possible, and when the time comes, I will not hesitate to reward! ”

"General Xie!"

…

After chatting with these craftsmen in this house for almost an hour, they were all calmed down, and their blood was boiling, and Xu Changqing was leaving.

They've already started to pack up their things, and they're going to get out of town soon.

At this time, he had to wait for the news from Liu Lang's side, Xu Changqing was actually a little worried and even apprehensive in his heart, so he didn't go to the city, but found a tavern at the south gate, ordered some braised meat, a plate of peanuts, and slowly drank a little wine and waited patiently.

As the old saying goes, "If you want to do a good job, you must first sharpen your tools!" ”

However, even if you have a plan, a plan, a plan, and a capital for many things, you can't do it right away, and there are many other factors.

It's called reality!

But Xu Changqing is by no means a person who sits idly by, even if he has to take a big risk, Xu Changqing started planning early.

The fierceness and ferocity of the soldiers of the Eight Banners of Manchuria do not need to be repeated.

To put it bluntly, fighting the front, Xu Changqing, a rookie who has been in the army for just a few months, is simply not the opponent of those battle-hardened Manchurian soldiers!

But this battle had to be fought!

Even, if there is a slight chance, you must win!

This requires good planning and brains.

Xu Changqing, who has 500 years of experience ahead of the world and already knows this era very well, of course understands very well that if you want to confront the Manchu soldiers head-on, the Ming army must have leading powerful firearms, powerful artillery, and powerful firearms!

However, reality cannot give Xu Changqing so much time, and he doesn't have so many resources!

Xu Changqing can only find other ideas!

Among them, the simplest, lowest-cost, most feasible, and easy-to-use is undoubtedly the most proficient 'grenade' in our military back then. Bounce it!

Even, even if it is the era of Xu Changqing's rebirth, grenades. Ammunition is still an important equipment and training subject for our infantry!

Xu Changqing definitely does not have the advanced technology of our army in later generations at this time, nor does he have the support of those time-tested science and technology trees, but Xu Changqing also has his advantages!

That's ------- bamboo!

Use a bamboo tube to make a simple but enhanced version of the flowering bullet!

It can be used to project, or you can use a trebuchet to cast and extend the range!

At this time, on Shark Island, Xu Changqing had already ordered Yang Hong to concoct and dry tens of thousands of sturdy bamboo tubes.

The bamboos on this side of the Green Snake Forest, including Shark Island, and many bamboos in the surrounding area, were almost cut down by Xu Changqing's sons.

After that, the capable and strong woman who was responsible for assembling these flowering bullets, Xu Changqing had already been ready for a long time!

In addition, Xu Changqing also prepared a large number of fresh bamboos, which could build at least fifty simple and strengthened catapults.

Others, including rain-proof and moisture-proof tarpaulin, oiled paper, as well as flints, fire folds, and many materials for making fuses, and other items, Xu Changqing has stocked up on a large number of them at a high price!

You can do it at any time!

However, although the idea is good, the concrete implementation must be tested by experiments!

Catapults and the like are not big problems, Li Zhu is an old carpenter, even if it is just made into a simple large slingshot shape, as long as it is easy to use!

However, the bamboo tube flowering bomb must be tested.

The main reason is that Xu Changqing is not proficient enough in gunpowder and does not know the ratio, and the gunpowder at this time cannot be compared with later generations.

However, Xu Changqing has a certain standard in his heart.

It is not required that these bamboo tube flowering bombs can produce much lethality, but the power must be fierce, and the Qing army must be chaotic!

Of course, under this premise, it would be great if it could increase its lethality!

But after the weapon is made, you still have to train people~.

Therefore, for Xu Changqing now, it is definitely a tight time and a heavy task!

…

The time soon came to the evening, and news came from Liu Lang's side, and the matter was done!

However, those 10,000 enemies were lost this morning, and they were soaked in water, and they were afraid that they would be ignited and burned down after a long time of storage, and the effect might not be so good...

"I'm @#¥%!"

As soon as Xu Changqing heard this, he really had the urge to kill!

Burn. There is no doubt about the effect of bullets on the modern battlefield, let alone the late Ming Dynasty at this time?

This is the best weapon to open the battlefield and divide the battlefield!

As long as it is used properly, it can build a wall of fire in a short period of time, and even the soldiers of the Eight Banners of the Manchu Dynasty will never want to rush over.

But at this time, these bastards, bastards who have more than enough success and more than failure, actually lost this kind of treasure?

Why did the hell soak in the water?

If Xu Changqing was the chief general of the Ming army at this time, he would definitely cut these bastards alive and stuff the grass!

But the matter has already happened, and anger can't solve the problem, Xu Changqing immediately asked Liu Lang to send someone over, and when he returns to the Green Snake Forest, let the craftsmen see if it can still be used.

If they can't be used, Xu Changqing will also have to disassemble them and build them again, and there must be some powerful weapons that can cut off the battlefield!

…

Soon, before the city gate was closed, Liu Lang arrived with these '10,000 enemies'.

Seeing that Xu Changqing's face was not very good, this guy didn't dare to ask Xu Changqing for credit again, he was a little gray.

Xu Changqing also came back to his senses at this time, and immediately gave Liu Lang more than 100 taels of silver, encouraged him well, and calmed his emotions, this is the way to go out of the city.

Back on the side of the Green Snake Forest, it was already completely dark.

Li Zhu and Niu Tendon have been sent to Shark Island by warship, and they will rush to make catapults overnight, including those who draw maps at night, and they will step up the mapping work to collect a lot of information.

Xu Changqing's side also quickly let people start to pack up gunpowder and 10,000 enemies.

Soon, after a few experiments, Xu Changqing was a little speechless that the effect of the 10,000 enemies who had been blistered was actually quite good, not to mention that the fire was too big, it was definitely a small fire with burning power.

Six or seven out of ten are very useful.

If the timing and environment of the action are well chosen, it is definitely promising!

The main thing is that the inside is very well sealed, and it is wrapped in several layers of oiled paper, just to be waterproof and moisture-proof, after all, it is produced in Beijing.

Of course, the main reason is that the time to soak in water is still short, and if you soak it for another day, it will be difficult to say.

But the power of gunpowder is hardly satisfying!

Even if it is Zhang Jiuye, they carefully selected the best batches.

Even if Xu Changqing doesn't understand, he can understand that there are many impurities in it, and the raw materials in all aspects must be cutting corners, or even fake!

This kind of fraud against the heavy weapons of the militarism, Xu Changqing really wants to kill people, and he definitely doesn't want to kill one!

If these gunpowders can't be used, then~, his Xu Changqing's plan will collapse across the board......

In this battle of Songjin, there is almost no room for manoeuvre......

After all, although Xu Changqing's command was a lot young and strong at this time, the one who could really fight on the battlefield was the earliest more than 200 soldiers.

This person, in the face of this kind of showdown between the two countries, is he a bird feather?

It's like a stone sinking into the sea, and it won't work at all......

Zhang Jiuye was also extremely annoyed, kneeling on the ground and kowtowing to Xu Changqing, saying that he had failed Xu Changqing's expectations.

Xu Changqing was so angry that he trembled!

Knowing this, he directly bought materials from the customs to make gunpowder himself, and that level of fraud was actually deceived even by a veteran like Zhang Jiuye!

With this ability, why can't they put this mind to the right path?????

It's a pity that there is no room for regret now.

I could only cheer up and let Zhang Jiuye and them try the batch of gunpowder that Li Hongyun and they had just brought over.

It doesn't matter if you try it!

Xu Changqing and Zhang Jiuye and the others suddenly seemed to be resurrected with full blood!

The gunpowder brought by Li Hongyun is much better than the more than 1,000 catties of gunpowder purchased at a high price through various channels in Ningyuan City!

According to Zhang Jiuye, although this can't let the carefully concocted bamboo tube blow up completely, it is probably no problem to blow it up.

After all, Zhang Jiuye is an expert in gunpowder, and he has been immersed in this way for decades, and he soon found the reason.

With a bitter face, he explained to Xu Changqing: "General, this, the gunpowder in these customs should come out of the people's workshop. There is competition in the private workshop, such as those fireworks and firecrackers, if you don't do it well, you will definitely not be able to do it. The gunpowder we brought from Ningyuan should be ...... It's all military quartermasters. What the craftsmen of the army make, here is ......"

With Zhang Jiuye's explanation, Xu Changqing also understood, and he really didn't know what it was like for a while.

Even if the bureaucratic system of the Ming Dynasty was a little careful, how could it have the mess it is now!

Really!

Zhang Jiuye went to inspect the seven or eight thousand catties of gunpowder sent by Hong Chengchou, which was completely a pile of rotten goods, not only with many impurities, but also with moisture, and basically unusable.

But the 10,000 catties of gunpowder on Li Hongyun's side are basically good products, at least more than 9,000 catties are easy to use.

This time, the gunpowder reserve that Xu Changqing had planned before was instantly discounted......

Fortunately, there is always better than nothing, according to the approximate amount of six or seven catties of gunpowder in a bamboo tube, it is enough for Xu Changqing to make more than 10,000 bamboo tube-type flowering bombs!

This amount should be almost enough.
