"Liu Yuanwai, how powerful is this artillery?"

Xiao Ming's voice reached Liu Chuang's ears through the smoke of gunpowder burning, which made him desperate. Pen ~ fun ~ pavilion www.biquge.info

Can King Qi, who has such a murderous weapon, still be defeated? The thought flashed through his mind and was soon shattered again.

In front of the city gate, Liu Wei's hoarse voice begging for mercy was suddenly heard, and the fear of death passing by made him almost crazy.

"I think Liu Wei will be more willing to tell the source of the gunpowder now, but if you still want to die a dignified death, I will give you this chance." Xiao Ming's voice was unwavering, and it seemed that the victory was in hand.

Liu Chuang chuckled in a low voice, he was defeated, and the moment the cannon exploded, fear permeated his whole body.

"The recipe for this gunpowder was handed down by my Liu family's ancestors." Liu Chuang said decadently, "I hope that King Qi can give me a whole corpse." ”

Superstition prevailed among the people of Dayu, and the common people all believed in the theory of reincarnation, and many believed that only a complete body could be reincarnated again, so it was a vicious curse to die without a corpse here.

The pit in the half-meter range of the city wall made Liu Chuang understand that if this cannon didn't break an arm and a leg, I was afraid that the whole person would be beaten into minced meat.

"I'm asking where saltpeter comes from." Xiao Ming asked, this is what he really cares about now.

Regardless of whether the King of Shu is in the way or not, the problem Xiao Ming is facing now is the shortage of gunpowder materials, which will cause him to not have enough gunpowder to deal with the barbarians.

"Hehe, if Your Highness wants to, just dig in the dung pit." Liu Chuang laughed.

Frowning, Xiao Ming was disappointed after all, he thought that Liu Chuang and the others held the location of the saltpeter mine, but he didn't expect that the saltpeter was obtained through this method.

He waved his hand and said to Niu Ben: "Kill them all, leave them all corpses." ”

Niu Ben nodded and gestured to Lu Fei and Luo Xin.

The two understood, the knife flashed, and Liu Chuang fell in a pool of blood.

The surrounding soldiers looked indifferent, a thousand of such a wealthy family died, and ten thousand were not a pity.

The artillery was test-fired, and at the same time the siege of Wubao was relieved, and it was time to collect troops and return to the city.

Now Xiao Ming has to find a way to solve the problem of nitrate, and now it is impossible to find the saltpeter mine immediately, but Liu Chuang's words made him make up his mind to find nitrate from the manure pit.

Asked Chen Fu to personally escort the cement to Cangzhou City, Xiao Ming said to Niu Ben: "Old general, although the wealthy clan of Liuzhou has been wiped out now, there are still many remnants of the rebellion, I hope that the old general will go to encircle and suppress, so as not to cause trouble in Liuzhou." ”

"Your Highness, this matter can be handed over to the last general, and it is our duty to raise troops for a thousand days and use them for a while." Niu Ben clenched his fists and said.

Xiao Ming nodded, Zhan Xingchang was supposed to be responsible for this matter, but the barbarians went south to break his plan, and now Zhan Xingchang is mainly responsible for the repair of Cangzhou City.

After the troops returned to the city, more than ten days passed in order to encircle and suppress Liu Chuang and his gang, but at least the artillery test firing was successfully completed, and then the equipment department could make every effort to produce artillery.

And he had to continue to solve the problem of saltpeter, which was one of them, and he needed a lot of bulk gunpowder to make gunpowder canisters.

Originally, he still had a glimmer of hope, thinking that Liu Chuang knew the location of the saltpeter mine, but now that hope is shattered.

However, he is not without gains, at least Liu Chuang proved that it is feasible to make nitrate from nitrate and then make gunpowder, and this nitrate pit is underground, but the amount is very small.

But now that the mosquito is small, it is still meat, and when he returned to the palace, he immediately asked Lu Tong to come over.

"There's saltpeter in the pit?" Lu Tong blinked, looking incredulous.

For Xiao Ming, there are still many ways to extract soil nitrate from the science and technology library, and the principle is very clear.

Generally speaking, the soil near pigsties, toilets, etc., in rural areas, often contains a large amount of organic matter.

After these organic matter decays, it is then reacted to by nitrifying bacteria to form nitric acid.

Nitric acid further reacts with arsenic, calcium, and magnesium in the soil to form potassium nitrate and its calcium, magnesium, and nitrate, which is fire nitrate.

In general, the fluffy white mold that precipitates on the earthen walls of pigsty and toilets contains high levels of potassium nitrate, sometimes as high as 75%.

explained the formation principle of saltpeter to Lu Tong, and at this time, Lu Tong understood and nodded slowly.

"It's a little more troublesome, but that's the way it can be now? Let's get over this first. Xiao Ming said.

If he could use saltpeter mines, no one would go to the toilet to find saltpeter, and he was forced to do nothing.

In addition to directly looking for saltpeter on the surface of the thatched pit and the soil wall of the pigsty, Xiao Ming also asked Lu Tong to dig the old soil under the toilet and cook the grass and wood ashes, so that the saltpeter crystals could also be extracted.

"Your Highness, this is no problem, when you say this, I remember that there is such a thing on my family's thatched pit, but a little, too little, how many thatched pits do you have to find." Lu Tong asked.

Xiao Ming already had an idea in his heart, and now he could only mobilize the vast number of people.

asked Lu Tong to go back to prepare the utensils, Xiao Ming asked Fan Zeng to come to the palace, and he personally wrote a draft and published it in the newspaper.

The content of this draft is to mobilize the people to find fire and salt from the thatched pit and hand it over to the local government, and anyone who provides fire and fire will be paid a penny per catty.

The next day, the news spread immediately along with the newspapers, and reporters from all the states went out at the same time, down to the counties and villages to convey the contents of the newspapers to the people.

"The white hair growing in this pit can still be sold for money?"

In Zhujia Village, Zhu Wuliu asked the person who had just finished reading the newspaper in surprise.

His elder brother Zhu Sansi has gone to Qingzhou City and successfully entered the Qingzhou Army, and now there are still eldest brother Zhu Yier, Zhu Xiaomei and him in the family.

Now that the grain will be harvested soon, the family is full of hope, but before the grain is harvested, his family is still very poor, but presumably it has been much better before.

Moreover, after Zhu Sansi entered the Qingzhou Army, the local government sent a stone of grain and a piece of cloth to his family.

These things make many people in the village envious, and no one would have thought that this soldier would also send food to eat, but they were all directly arrested to be soldiers in the past.

Because of this, many hesitant people in the village went to join the army, because every time the government sent something home, it was a glorious thing and a matter of light on their faces.

In addition to his second brother, his eldest brother is now on the dock for the merchant ships to unload and load goods.

In the past six months, the number of merchant ships coming and going to Qingzhou Wharf has increased sharply, and there are many people who need to carry goods, and the wages have naturally risen again and again.

Zhujia Village is not far from the wharf, and the strong men in the slack time basically go to the wharf.

Compared with the eldest brother and the second brother, Zhu Wuliu has been helping to watch the family's fields at home, but he also wants to be able to earn some silver.

Therefore, he was immediately moved.
