Early the next morning, after a day of publicity specially arranged by Xiao Yao and Li An, the entire Xunyang County already knew that Lin Taishou was corrupt and perverted the law, and was punished by God, and a large amount of gold, silver and jewelry were found at home.

And Li An relied on the prestige advantage of the local snake and the sponsorship of Xiao Moke, a high-ranking official of the imperial court, to temporarily take over his position.

Li An immediately ordered to take out the confiscated Lin Taishou's embezzlement and use it to requisition the horses of the whole city at a high price, and set up a cavalry to prevent the Julong Gang from robbing the law field.

Soon, Li An handed over the more than 50 horses and 50 carefully selected cavalry collected in the city to Xiao Moke for training, after all, it was related to the safety of Xunyang County, so Xiao Moke also readily agreed to train this temporary cavalry on his behalf.

Li An handed over 300 soldiers to Zhou Chao, and Zhou Chao immediately divided the soldiers into three teams: one team was responsible for collecting charcoal, because of the support of the people of the entire Xunyang County, every household took out all the charcoal left over from their own winter, and soon bought hundreds of catties of charcoal.

One team was responsible for selling the sulfur of the entire county, and even had to go to nearby towns to buy it, and finally collected more than 200 catties of sulfur!

And Zhou Chao himself personally led a team of people to refine the last material according to the soil method taught by Xiao Yao - nitrate! Because Xunyang County is not a saltpeter production area, the situation is urgent, and you can't buy much saltpeter if you have money, so you can only rely on your own production.

Xiao Yao's soil method is called: Drain nitrate! The raw material is the old wall soil such as toilets and cowsheds, because the organic matter such as feces is decomposed to form ammonia, and ammonia is generated into nitric acid under the influence of nitrifying bacteria, and nitric acid reacts with carbonate in the soil to form nitrate, so the main components of these old wall soil are calcium carbonate and calcium nitrate.

Zhou Chao mixed the old wall soil dug up by the soldiers with grass ash, poured it into a large vat and soaked it in water, so that the calcium nitrate in the wall soil and the potassium carbonate in the grass ash reacted to produce a potassium nitrate solution.

Then put the filtered and clarified solution into the cauldron to heat and evaporate, this step is the most critical: when the solution has crystal precipitation, the solution should be poured into another basin to cool, because the temperature has a great influence on the solubility of potassium nitrate, and the temperature is slowly cooled to precipitate relatively pure potassium nitrate.

Through repeated cooking and cooling and careful drying, Zhou Chao finally rushed to produce less than 100 catties of pure potassium nitrate.

When Xiao Yao mixed the purified and dried potassium nitrate, sulfur, and charcoal into black powder in proportion, two days had passed, and tomorrow would be the decisive day!

"This pile of black powder is Shiro, what you call black powder? Is that the black powder in your powerful musket? Ang Lee was surprised.

Because he had seen the power of the musket, at first he thought that there was something rare in it, but he found that it was just a pile of inconspicuous things, and of course he did not know that it was made of nitrate, toner, and sulfur powder.

"This is black powder, don't underestimate them, they are extremely powerful when they explode, and they will definitely blow up those water thieves when the time comes! Brother Li, what about the bamboo tube I asked you to prepare? Xiao Yao was very confident, because he had already tested this batch of black powder and was of high quality.

"It's ready, according to your requirements, the bamboo tube with a large bowl mouth, sawn into a section, has a small hole, each can hold more than three catties of water!." Li An immediately asked people to bring hundreds of bamboo tubes.

"Okay, immediately order to go up, mix these black powder into the gravel, wrap it in paper, put it into these bamboo tubes, plug in the fuse, and then plug the mouth of the tube! I'll show you what a grenade bomb is! Xiao Yao couldn't wait to try this bamboo grenade bomb.

Li An took Xiao Yao and others to the outside of the city, and saw that Xiao Moke's father and son were training the formation of the cavalry: after two days of training, the temporarily formed cavalry began to look a little, and the momentum of the array was murderous.

"Lord Xiao, how are the cavalry trained? Tomorrow's cavalry assault will be very important. Xiao Yao asked.

"Haha, Shiro rest assured, although the original fifty people were eliminated by me and only these thirty people remained, it is no problem to use this cavalry to deal with those hundreds of water thieves, but the premise is that Shiro wants to let the water thieves mess up without a fight!" Xiao Moke already knew Xiao Yao's battle plan, but he was very curious about what means Xiao Yao used to make hundreds of strong water thieves mess around, so that this team of temporary cavalry could rush forward.

"Haha, we're here to show you my secret weapon, let's go, let's find a remote place!" After speaking, Xiao Yao led the group to a wasteland.

"Lord Xiao, tomorrow we will tie up a group of water thieves under the city wall, lure the river dragon to come to rescue people, and when they rush to the city, we will throw these things down on it! Senior brother, let everyone see! Xiao Yao asked Gao Yuan to take out the bamboo grenade bullet.

I saw Gao Yuan holding the handle tied to the bamboo tube, lit the fuse, sounded sizzlingly, and then vigorously threw it at the haystack more than 30 meters away!

Rumble! The haystack was blown to pieces!

Everyone was so frightened by this loud noise that they jumped up, their eyes were stunned, it was so powerful, a fist-sized bamboo tube had become so powerful!

"When the time comes, we'll throw hundreds of these things into the water thieves and explode with a bang, do you think they'll be scared and run around with their heads in their hands?" Xiao Yao looked at Xiao Moke proudly.

"What is this, it's louder than thunder, don't talk about water thieves, we're all shocked just now when we're so far away!" Xiao Moke asked in surprise.

"This is the secret weapon I made, the little one can be held in the hand, louder than thunder and powerful, so it is called a grenade bullet! When the time comes, first use this thing to blow up the water thieves everywhere, and then capture the thief first capture the king, take advantage of the chaos to shoot the tyrannosaurus, and then the cavalry in the ambush in the city gate suddenly impacts, and they will be ordered to flee in the wilderness, and Brother Li, who was ambushed around in advance, will lead people to rush up, and he will definitely be able to wipe them out! Xiao Yao said confidently.

"I see, this thing is the same as the inside of your pistol! No wonder the pistol could make such a loud noise at that time! Play with that pistol for me again! Xiao Wuhua, who suddenly realized, ran to Xiao Yao's side excitedly, and reached out to touch the pistol on Xiao Yao's waist.

Xiao Yao took the opportunity to grab Xiao Wuhua's jade hand and teased: "Wuhua, although I know I'm handsome, you don't have to be so enthusiastic about me?" Everybody is watching. ”

"You, you, let me go!" Xiao Wuhua, who was carried away by the excitement for a while, reacted, and saw that everyone was snickering, even Xiao Moke's face was a little embarrassed, and he hurriedly blushed and wanted to break away from Xiao Yao's salty pig hand.
