The spring breeze in February is like scissors, cutting off heavy winter clothes, cutting out tender green shoots, and also cutting out a wide canal......

Since the formal construction on February 2, in seven days before and after, the river channel 15 miles long and 10 zhang wide has been repaired, and the speed is so fast that it is like a trick.

People who are so lively run to the outside of the city every day, looking at the construction site, whenever they see the novelty, they can't help but dance and marvel, surprised and admired, more lively than watching the temple fair.

On the third day, after the water was diverted to wash the river, a huge rock was exposed, and the three teams worked together, and the hemp rope was broken several times, and then the wooden frame was also damaged, and two strong men fell and were injured, and they couldn't pull it out.

Finally encountered a hard bone, the people who have repaired the river in the past know in their hearts, encountering thousands of pounds of big stones, unless they are smashed a little bit, a little bit cleaned, there is no other way, not to mention ten days and half a month. In addition to the immortals, no one has the ability to lift 10,000 catties, not to mention that there is an extremely sticky mud sucking, and it is more difficult to get it out than to ascend to the sky. Some ill-intentioned guys are waiting to see the excitement.

Ye Sheng was very calm when he got the news, and after taking someone to check it, he immediately asked everyone to give up temporarily and clean up other places.

About a quarter of an hour later, dozens of people came with bamboo baskets on their backs, shovels and pickaxes, climbed onto the stones, knocked and beat, and left again and again for a long time.

Just when everyone didn't know why, all the people near the big stone withdrew, and after a while, a muffled thunder was heard, and the earth trembled. Thick white smoke rose from the river, and large chunks of silt were blown a hundred paces away. Far away, everyone who looks at the excitement feels their ears buzzing.

After a long time the smoke and dust dissipated, there was still no trace of the big stones, only the gravel was left everywhere, and the workers swarmed up, and after a while, they cleaned up and continued to rush to the next target.

Gunpowder!

Actually with gunpowder!

It's crazy to see the excitement, the construction guy has not never seen it, the most extravagant thing is to burn it with a large fire first, and then suddenly pour cold water, using the principle of thermal expansion and cold contraction, to break the stones. Exploded with gunpowder, it is simply unheard of and unseen. After being shocked, everyone inquired curiously, and when they heard that this construction method was proposed by Ye Sheng, they were happy again.

Our first name is Xie Yuan, it is really amazing to be able to come up with such a wonderful method, and everyone is honored. Someone even brought their own bear children and let them watch it, so that they could be smoked and become smart in the future.

Not only them, but even Zhou Jun was shocked.

Ye Sheng once handed her the purchase list, and when Zhou Jun saw that there were 20,000 catties of gunpowder on it, this Zhou Jun was immediately angry, and he really couldn't think of any other use for gunpowder except for being used in the army. Could it be that you want to take my money, buy gunpowder, and give it to the army?

My Zhou Jun's eyes couldn't tolerate sand, he was furious and found Ye Sheng. It turned out that Ye Sheng was leading a group of people to dig the soil of the toilet!

The foul smell made him almost vomit, Ye Sheng smiled and accompanied him to the front.

Ye Sheng laughed and said, "Zhou Jun, my stinky body can be exchanged for a lot of silver." ”

"Hmph, there are a lot of nonsense!" Zhou Jun didn't believe it at all.

"How do you understand, if you want to produce gunpowder, you need three things, sulfur, saltpeter, charcoal, and there is saltpeter in the soil of the toilet stable, add plant ash, put it in the cauldron to heat, dissolve, filter, and the crystals that precipitate are pure saltpeter, which can be used for **."

Ye Sheng said a string of nouns, Zhou Jun couldn't understand any of them, and asked blankly: "What are you making gunpowder for, is it possible to gather a crowd to rebel?" ”

Poof, a sip of tea squirts far away, imagination is so rich!

Ye Sheng's face turned red with choking, who let the family pay, he had no choice but to tell the plate, "Zhou Jun, if you want to build quickly, it is necessary to blast with gunpowder." But it was no joke that the privately built gunpowder workshop was poked out, so I decided to borrow chickens to lay eggs. ”

Although Zhou Jun didn't know what it meant to borrow chickens to lay eggs, he knew that Ye Sheng was using gunpowder to repair the canal, and most of the anger in his heart disappeared, and he asked curiously, "What do you want to do?" ”

"There was originally an ordnance workshop in Taicang, which was supplied to Baoshanwei, which could produce hundreds of catties of gunpowder a year. As for me, if I place an order of 20,000 catties to the workshop, the ordnance workshop will definitely not be able to produce it. Then he asked the imperial court for permission to expand the scale, and took advantage of the situation to hang our workshop under the imperial court's ordnance workshop, and started at full power to produce gunpowder, and the wealth rolled in. ”

"Wait." Zhou Jun hurriedly waved his hand, a little unable to keep up with Ye Sheng's train of thought, and said suspiciously: "Isn't the canal able to be completed in half a year, producing so much gunpowder and making firecrackers?" ”

And that's the only use she can come up with.

"Mr. Zhou, the Western Xia is making such a big fuss, the imperial court will definitely have to transfer troops over on a large scale, how much military supplies will be consumed? The gunpowder workshop is a big business, not only to make money, but also to build up with the army. Although he is noble and martial, when it comes to fighting, he has to speak with his fists. ”

After listening to Ye Sheng's idea, Zhou Jun thought for a long time and muttered: "It sounds like selling dog meat on the head of a sheep, not like borrowing chickens to lay eggs?" ”

Just thinking about this, Ye Sheng almost fainted.

"Mr. Zhou, do or not do a word?"

"Do it, why don't you do it, in the future, all your Ye Sheng's business will be counted as Mr. Ben's share!" Zhou Jun said happily.

Since the gunpowder was brought out, the construction of the canal has been rapid, and in mid-February, everyone came
