The warm wind floats, blowing the golden wheat waves in the fields.

Zhujia Village, close to the wheat field, was in full swing at this time, and every household was busy looking for fire salt in their own cesspools.

Zhu Wuliu ran the fastest. At this time, he had a handful of white powder on his hand. He searched carefully the pit at home. Zhu Wuliu carefully wrapped the white powder and immediately went to Qingzhou City.

"Zhu Wuliu, go and have a look first. If it can be sold for money, we will go."

"Yes, you run fast, we'll wait for you to come back."

“…”

Many people in the village are digging, and many people are watching. The suffering people are not yet fully trusting the government office.

Although the farming order and the production team gave them some benefits, the deep-rooted impression of the government office in their hearts was difficult to change for a while.

They were afraid that they would just send their things in vain.

Zhu Wuliu's steps did not stop. His brother Zhu Sansi was in the army. He believed in the current Qingzhou Prefecture and the current King of Qi more than others.

Holding the white powder tightly, Zhu Wuliu arrived in Qingzhou City and went directly to the government office.

At this time, at the entrance of the government office, a boy of similar grade seemed to be waiting for something. Zhu Wuliu hesitated and stepped forward and asked, "Is it possible to buy fire salt here?"

This young man was Lu Tong's subordinate. In order to distinguish between fire and salt, Lu Tong sent Fuyu people to various prefecture government offices to be responsible for the acquisition.

"That's right." The boy said in surprise.

So far, no one has come here to pay saltpeter, and this teenager is the first one.

Zhu Wuliu breathed a light sigh, handed over Huoji, and said, "I have found so many."

There was a pounding point in front of the boy. He weighed the things Zhu Wuliu brought and said, "There are five taels in total, because you are the first one. Your Highness said that the saltpeter brought by the first hundred people was purchased at 20 cents per kilogram to encourage it. This is ten cents, get it."

When ten copper coins were reached, Zhu Wuliuxi smiled.

At this time, the boy said to Zhu Wuliu: "By the way, there is another way to get more saltpeter do you want to learn?"

"Think!" Zhu Wuliu agreed without hesitation. The temperature of the copper coins in his hand made him believe in the Qingzhou government office.

The boy nodded and told Zhu Wuliu how to dig out the pit and mix old-fashioned wood ash to make hot salt.

Zhu Wuliu nodded and immediately returned to the village.

Seeing Zhu Wuliu come back at this time, many villagers surrounded him and asked, "Wuliu, how are you?"

Zhu Wuliu lit up the copper coins in his hand, "I just said that our highness will not deceive the people. The people in the government said that the first one hundred people will be purchased by 20 cents per kilogram."

As soon as these words were said, the people around Zhu Wuliu immediately ran away. When they got home, they picked up the saltpeter at home and ran towards Qingzhou City.

In an instant, hundreds of people seemed to be chased by dogs.

Zhu Wuliu smiled, pinched the copper coins in his hand, thinking about how to use the money he earned himself?

At this time, the news that fire salt can really pay back money was spread out, and ten spread out slowly, and more people joined the search and production fire salt.

After half a month's shortage of chemical laboratory materials in Qingzhou Chenggongfang District, the first batch of saltpeter was shipped. Although these saltpeters had a strong urine smell, they were generally better than none.

"Your Highness, you are so amazing. You solved the problem of saltpeter in this way. Hehe, the King of Shu still wants to control your highness. Now it seems that he has no place to sell saltpeter in the future."

Lu Tong fainted from a bag of saltpeter sent by him, but he was still dancing happily.

Xiao Ming smiled bitterly. If he could use normal saltpeter, who would go to the cesspool to find it?

And this is never a long-term solution. After all, the formation of saltpeter also takes time. This folk method of obtaining saltpeter cannot replace saltpeter ore after all.

This time he disclosed the method of earth and salt, one for the purpose of helping the emperor, and the other for disgusting the King of Shu.

When the people of the entire Great Chongqing country knew how to get saltpeter, he saw where to sell saltpeter in Shu.

"Now that this saltpeter is sufficient, so as much gunpowder should be prepared as much as possible." Xiao Ming ordered.

Regarding King Shu, he has not returned from his letter to Chang'an, and I don't know how Xiao Wenxuan will deal with this matter.

But no matter what, he temporarily passed this level.

With enough gunpowder, he will think about how to throw gunpowder jars.

Xiao Ming has his own idea about this gunpowder jar, and his weapons will never be single on the battlefield.

This cannon is used to deal with catapults and enemies that are far more harmful, but this gunpowder tank is different. It is to kill the barbarian army gathered under the city to climb cloud ladders.

The power of this pottery pot lies in the fact that it can contain a large amount of gunpowder. If this gunpowder explodes and is just a shock wave, it can cause the barbarians to turn over. This is different from the linear killing of artillery, but is a range killing.

In view of the fragile shortcomings of the clay pot, Xiao Ming planned to wrap a thick layer of straw outside the clay pot and tie it up layer by layer.

As long as small trenchers are set up on the city wall at that time, the long-range artillery can be fully realized, within 200 meters of the trencher, and the short-range coverage of soldiers thrown by the barbarians can enjoy the feast of gunpowder at any location.

While thinking about this crazy defensive tactic, Xiao Ming went to the Equipment Department. Chen Qi is very busy now, but there is no way. This matter has to be left to him...

At the same time, a group of unpopular people arrived in Chang'an City.

These people were barbarian envoys from the Golden Horde. Their arrival broke the calm atmosphere of Chang'an City. From first-rank officials to the people, everyone was spy on the purpose of these barbarian envoys coming.

This will also mean that the Great Chongqing Kingdom and the Golden Horde will be in war or harmony in the future.

"Three messengers, please go to the inn to have a rest. Tomorrow, Your Majesty will summon three messengers from afar."

The envoy responsible for entertaining the barbarians was Zhao Xing, the Minister of the Honglu Temple. The Honglu Temple was responsible for handling foreign envoy affairs in the Dayu Kingdom.

"Tomorrow! Today we will meet your emperor, which has delayed our major affairs, be careful of the dog's head!"

The barbarian envoy who came this time was tall, with hair draped behind him, with braided braids hanging on both sides, with golden rings on his ears flashing with a cold light, dark face and a cold expression.

With him were two guards wearing leather armor and felt hats, and one of them was the one who spoke rudely at this time.

Zhao Xing was shouted and couldn't help but feel a little scared.

This barbarian tribe is powerful, and the officials from all over Chang'an are arrogant, and Zhao Xing is of course one of them.

When he saw this barbarian envoy, his legs trembled and his mind was panicked, fearing that the barbarians would be lively.

"Sir, Lord," Zhao Xing smiled flatteringly, "The subordinates are also conveying the emperor's will. I am really powerless. Please forgive me, three adults. I will arrange wine and good food for the three adults immediately, can I?"
