Saying that, on Chen Gui's side, not long after continuing to march, he found the pioneer battalion that really escorted Wu Sangui's family. Pen % fun % Pavilion www.biquge.info

After some inquiry, it was revealed that one woman had indeed escaped from the family, and that ten brothers were missing, and they were looking for them nearby.

Fortunately, when Li Hongfei took off the other party's clothes, he had ordered someone to hide the body, otherwise letting the pioneer battalion find it would definitely arouse the vigilance of the intruding army.

"No need to look for it, earlier I met a group of people from the pioneer battalion, escorting a woman away, and it seems that the woman has been ruined, it is really undisciplined and shameless!" Chen Gui pretended to be angry and said.

Due to the heavy fog and Chen Yuanyuan's factors, Chen Gui didn't bother to pay attention to the number of people in Li Hongfei and his entourage, but he felt that the number of people was not large, which just coincided with the number of missing pioneer battalions.

Until this time, he did not suspect the identity of Li Hongfei and others, but deliberately provoked, saying that Li Hongfei and others ate alone.

It can only be said that people with dirty hearts look at problems equally dirty, if Chen Gui can react at this time and turn back to pursue Li Hongfei and others, maybe it is really possible to catch up.

But not only did he not find anything wrong, but he also indirectly helped Li Hongfei and his party, so that the soldiers of the pioneer battalion ended the search operation, and when the pioneer battalion returned to Liu Zongmin's account and found out about the scheme, Li Hongfei and his party had already fled.

And Li Hongfei and the others, after getting rid of Chen Gui, quickly turned north and headed towards Shuntianfu, which had not yet been occupied by Li Zicheng's army, and the speed of everyone along the way also accelerated a lot, and it didn't take long to come to the Shuntianfu Weapons Bureau.

The guards of the Ordnance Bureau all fled early, and among the yamen, overturned tables, chairs, benches, and metal utensils of little value in the house were all gone, as if they had been looted by bandits.

"I've searched all over the place, these guys are so unreasonable, not to mention firearms, even the kitchen knives in the kitchen have been looted." Wang Guoxing searched and came back to report.

This is the case in the era of war, the defeated army is scattered, without the restraint of the generals, the low morale of killing needs to be vented, most of these people will form a wind of robbery, and the Ordnance Bureau has a lot of weapons stored, which is naturally the preferred target of these routs.

And if these routs who fled after the robbery still had weapons in their hands and were not absorbed by the regular army, it would not be long before they became a tributary and endangered local law and order.

This is also the main reason why no matter which dynasty, after the war is pacified, the people in power will always take out a large part of the army and spend years or even decades to go to various places to suppress bandits.

"There are still a lot of raw materials for making gunpowder in the warehouse, and they are all polished, but there is no recipe, and there is no gunpowder master, so we can't make gunpowder." A brocade guard brought not too bad news.

The so-called raw materials are nothing more than saltpeter, sulfur, charcoal and other carbon-containing substances, which are rough-processed and made into real gunpowder only in a certain proportion when the workers need them.

But now there is no formula, and there is no pharmaceutical master, even if the raw materials are found, it will be in vain.

"I know the recipe, so Wang Guoxing asked you to prepare eighty catties of saltpeter, ten catties of sulfur, and fifteen catties of charcoal for me, and mix them evenly." Li Hongfei said the recipe for black powder.

Speaking of this gunpowder formula, it was an allusion that impressed him when he was still in high school chemistry, so he remembered it vividly.

When I was studying, when I talked about the formula of black powder, I often mentioned an allusion, that is, "one sulfur, two nitrate and three charcoal", and Li Hongfei found that the chemical formula obtained according to such a ratio did not meet the basic conditions for explosion at all.

To put it simply, the final result of the black powder configured in such a ratio can only burn, but cannot produce a violent explosion.

So with this kind of doubt, Li Hongfei checked the Internet, and finally got an answer that impressed him.

It turns out that the popular allusion is "one sulfur, two sulfur and three charcoal", not the so-called "one sulfur, two sulfur and three charcoal", and the ancients said that "one nitrate" refers to one catty of nitrate, and "two sulfur and three charcoal" is 2 taels of sulfur and 3 taels of charcoal.

In addition, the conversion formula of 1 catty and 16 taels in ancient times means that the formula ratio of ancient black powder is, 16 nitrate, 2 sulfur and 3 carbon, which is very close to the modern formula.

Although Li Hongfei forgot the best ratio of black powder, it is absolutely no problem to mix the ratio of black powder according to 80:10:15.

Arrange someone to mix gunpowder here, Li Hongfei himself was not idle, he searched carefully in the Ordnance Bureau, and sure enough, he found a lot of waterproof oil paper and hemp rope.

Gunpowder is an extremely difficult material to store, and the ancients also understood this truth, so waterproof and moisture-resistant oiled paper has become an indispensable utensil for the Ordnance Bureau, and these things are similar to the raw materials of gunpowder, and they have little effect on the rout, so they have not been robbed.

Li Hongfei happened to use waterproof oilpaper to make explosives bags.

"Will this work? A few pieces of tissue paper can blow open the city gates? Do I need to fill in some rocks or something? Wang Guoxing asked.

In order to increase the lethality of gunpowder after the explosion, the ancients often filled it with a large number of gravel, tribulus terrestris and other utensils, but now Li Hongfei is only filled with pure gunpowder, so Wang Guoxing is still not at ease.

"What we need is the impact of the explosion, not the lethality of the fragments, forget it, you don't understand it after telling you, hurry up and help me pack it, remember, it must be tied tightly, even if it is put into water, not a drop of water can penetrate into the gunpowder." Li Hongfei said.

More than 100 catties of explosives bag, his little arms and legs are quite difficult to tie, and now that he has ready-made labor, Li Hongfei will not miss it.

As for the sealing performance of the explosives package, even if you explain it to the other party, the other party can't hear it clearly.

The first time he made an explosives bag, Li Hongfei was also quite realistic, and he wrapped five layers, so he was relieved, of course, he didn't do it himself.

Looking at the bag of explosives, which was the size of a grain bag and weighed more than 100 catties, Li Hongfei muttered in a low voice: "Sample, so much gunpowder, I don't believe that the city gate can't be blown up." ”

The group tossed for a lot of time, and it was early in the morning when they arrived at Ding'anmen.

Originally, after marching for most of the night, they should have a good rest, at least they had to eat some food to replenish their strength, but time waited for no one, they marched secretly all the way, and after turning north, most of the surrounding houses were looted by the rout, not to mention horses, and even a wheelbarrow could not be found.

The longer the time is delayed, the more Li Hongfei and the others who have not yet walked out of Andingmen, it will be the turtle in the urn.
