Iron Dynasty

Mr. Liu, how powerful is this cannon?

Xiao Ming's voice reached Liu Chuang's ears through the smoke of the burning gunpowder, which made him despair for a while.

Can King Qi with such a murderous weapon still be defeated? This idea flashed in his mind and was soon broken again.

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

I think Liu Wei would be more willing to reveal the source of the gunpowder now, but if you still want to die with dignity, I will give you this chance. Xiao Ming's voice seemed to have no waves.

Liu Chuang laughed twice, he was defeated, and the moment the artillery exploded, fear filled his body.

The formula for this gunpowder was passed down by my Liu family's ancestors. Liu Chuang said decadently, I hope King Qi can give me a whole body.

Superstition prevails among the people of Dayu. All the people believe in the theory of reincarnation. Many people believe that only a complete body can be reincarnated again. Therefore, death without a whole body is a vicious curse here.

The half-meter-wide pothole on the city wall made Liu Chuang understand that if he didn't break an arm and a leg, he would probably be beaten into minced meat.

What I'm asking is where does the saltpeter come from. Xiao Ming asked, this is what he really cares about now.

Whether or not the King of Shu is a stumbling block, the problem Xiao Ming faces now is the shortage of gunpowder materials, which will cause him to not have enough gunpowder to deal with the barbarians.

Hey, if Your Highness wants to, just dig in the cesspool. Liu Chuang laughed.

Frowning his brows, Xiao Ming was disappointed after all. He thought that Liu Chuang and others had the location of the saltpeter mine, but he did not expect that the saltpeter was obtained through this method.

He waved his hand and said to Niu Ben, Kill them all and leave them with a whole body.

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

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

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

The artillery was tested, and the siege of Wubao was relieved. It was time to withdraw troops and return to the city.

Now Xiao Ming must find a way to solve the problem of nitrate. It is impossible to find the saltpeter mine immediately, but Liu Chuang's words made him determined to find nitrate from the cesspool.

Let Chen Fu personally escort the cement to Cangzhou City, Xiao Ming said to Niu Ben: Old General, although the six states have been wiped out, there are still many remnants in chaos. I hope the old general will go to encircle and suppress the six states, so as not to disturb the six states.

His Royal Highness, this matter can be handed over to the last general. It is my duty to raise troops for a thousand days and use them for a while. Niu Ben said with his fists folded.

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

After the soldiers returned to the city, more than ten days passed in order to encircle and suppress Liu Chuang's group, but at least the artillery test was successfully completed, and then the equipment department could fully produce artillery.

And he has to continue to solve the problem of the saltpeter, the artillery is one of them, and he also needs a lot of bulk gunpowder to make the gunpowder can.

Originally, he still held a glimmer of hope, thinking that Liu Chuang knew the location of the saltpeter mine, but now his hope has been dashed.

However, he was not without gains. At least Liu Chuang proved one point. It is feasible to make nitrate and then make gunpowder, and there is a pit underground, but the amount is very small.

But now mosquitoes are meat no matter how small they are. When he returned to the palace, he immediately called Lu Tong over.

Is there saltpeter in the pit? Lu Tong blinked in disbelief.

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

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

After these organic substances are corrupted, nitric acid is generated by the action of nitrifying bacteria.

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

In general, the fluffy white mold that precipitated on the dirt walls of pigsties and toilets had high potassium nitrate levels, sometimes as high as 75%.

He told Lu Tong about the formation principle of saltpeter. At this time, if Lu Tong understood something, he nodded slowly.

This method is a little more troublesome, but that's the only way to do it now? Let's get over this difficulty first. Xiao Ming said.

If the saltpeter mine could be used, no one would go to the toilet to find saltpeter, and he was forced to do so.

In addition to directly looking for the pits and saltpeter on the surface of the pigsty's soil wall, Xiao Ming also asked Lu Tong to dig the old soil and plant ash under the toilet to cook, so that the saltpeter crystals can also be extracted.

His Royal Highness, this is not a problem. After you say that, I remember that there is such a thing on my kennel, but it's too little. How many kennels need to be found. Lu Tong asked.

Xiao Ming already had an idea in his mind, and now he can only mobilize the majority of the people.

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

The content of this manuscript is to mobilize the people to find fire nitrate from the pit and hand it over to the local government. Anyone who provides fire nitrate will be paid one penny per catty.

The next day, the news spread with the newspaper immediately, and reporters from various states dispatched at the same time, went down to the county, and the village conveyed the content of the newspaper to the people.

Can the white hair growing in this hut 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 had already gone to Qingzhou City and successfully entered the Qingzhou Army. Now there are only elder brothers Zhu Yier and Zhu Xiaomei and him at home.

Now that the food can be harvested soon, the family is full of hope, but before the food is harvested, his family is still very poor, but it must have been much better in the past.

And after Zhu Sansi entered the Qingzhou Army, the local government office sent a stone of food and a piece of cloth to the family.

These things made many people in the village envious. No one would have thought that this soldier's government office would also send food to eat. In the past, he was directly arrested and served as a soldier.

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

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

In the past six months, the number of merchant ships going to and from Qingzhou Wharf has increased sharply, and many people are required to carry goods. Naturally, the wages have risen again and again.

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

Compared with the eldest and second brothers, Zhu Wuliu has been helping to look after the fields at home, but he also wants to earn some money.

Therefore, he was immediately moved.
