Xiao Chenxuan was very tearful, how does it feel like digging a muddy pond to build a pond, the water storage capacity is extremely poor, although the craftsmen of the palace have repeatedly treated the pond with glutinous rice, but the result is still unsatisfactory.

And at this moment, Wang Fugui, the housekeeper of the Ji Palace, walked in, followed by Zhang Laosan, the village leader of the General Village, and after the two greeted Xiao Chenxuan, Zhang Laosan immediately opened up.

"Lord Wang, the spring ploughing has ended, I don't know what you said, build the road of this general village to the imperial city, I don't know when it can be repaired?"

"Build roads, yes, build roads, this king has planned." Xiao Chenxuan remembered that the villagers of the General Village, who could not enter the world restaurant and the winery, repaired the road in the General Village to the Imperial City after the spring ploughing, and remembered that he shouted to the old man Zhang Laosan at that time, if you want to get rich, you must build the road first.

But if it is a cement road, it is conceivable that the first cement road in the world can be spread throughout China?

Cement, Xiao Chenxuan at this time suddenly reacted, no wonder to repair a pool, the craftsmen tinkered for so long, and it was so unsatisfactory, it turned out that it was not that glutinous rice was bad, but that there was no cement at all in this era, Xiao Chenxuan immediately made a decision in his heart, the research and manufacturing of cement was imminent, fortunately, he also knew the approximate production process, and after thinking for a while, he replied to Zhang Cunzheng.

"Zhang Cunzheng, you go and organize people to start building the road, this king is not very demanding, you can pass through three carriages at the same time when you come back."

"Three carriages, this, but..."Zhang Laosan's face was full of embarrassment, a group of old, weak, sick and disabled, how could they do such a huge project?

"Huh? If you have any difficulties, tell this king directly, and this king will solve them for you as much as possible. ”

"Lord Wang, that's the case, if you want to dig out three carriage lanes, you have to widen a large area on the basis of the original road, and this widening will encounter a large number of rocks, but the young and middle-aged people in the general village either enter the prince's escort corps, or go to the prince's winery, our remaining group of old, weak, sick and disabled, it is difficult to knock down those rocks!"

Xiao Chenxuan was just sudden, if he couldn't beat it, then blow it up, wouldn't it be over? But how to blow it up? Doesn't gunpowder be needed to explode the cannon?

Gunpowder? Black gunpowder, Xiao Chenxuan then remembered that among the four major names, gunpowder was invented very early, and it had already begun to be used in the military in the Tang Dynasty.

At this time, isn't the era name of Tianshun Kingdom similar to that of the Sui Dynasty? Gunpowder should have appeared, but people at most used it as a salute for the New Year, and the real black powder, if it does not appear by itself, I am afraid that it will take hundreds of years of history!

Didn't he let Zhu Laosan's three sons tinker with this firecracker? Why don't you put this black powder on the agenda, so that it can be used both militarily and civilly?

Xiao Chenxuan turned his head and looked at the old man Zhang Laosan up and down, but he didn't expect that this old man was still his own lucky star, every time he encountered a problem, he would appear, and he also provided himself with new ideas.

Looking at Xiao Chenxuan looking himself up and down, Zhang Laosan, the old man, was also stunned, what did the prince look at himself, he was a bad old man, less than a hundred catties of meat! It's not worth a lot of money if you sell it! It's weird! Then he stammered and asked.

"Lord Wang, I, I, I don't have anything on me."

"Haha, Zhang Cunzheng, you are really the king's lucky star, every time the king encounters a problem, your appearance has provided the king with new ideas, haha, not good, the king began to like you as an old man, this way you can rest assured to organize people to repair, the problem of mountains and rocks, this king will solve it for you, Lao Wang, when Zhang Cunzheng goes back, remember to bring a pig's leg to the village!"

After Xiao Chenxuan finished speaking, he directly took out a hundred taels of silver from his arms. directly rewarded Zhang Cunzheng, and Zhang Cunzheng, who took the silver, was even more confused, what problem did his appearance solve for the prince? The prince is so good to himself, and he is still very uncomfortable!

As soon as Zhang Laosan left, Xiao Chenxuan immediately asked Steward Wang to notify Zhu Laosan's three sons and all the stonemasons in the palace to come to his study.

Zhu Laosan's three sons, who received the notice, were very excited, holding the guns that the three brothers had studied for many days, and ran to Xiao Chenxuan's study non-stop, as soon as they arrived at the door of the study, they saw that the prince was discussing something with a group of stonemasons in the palace, so they had to silently withdraw from Xiao Chenxuan's study, and the three of them stood stupidly, waiting for the summons of their prince.

After a while, the craftsmen in Xiao Chenxuan's study left one after another, and the three of them looked back and forth in Xiao Chenxuan's study, looking at the appearance of the three of them, Xiao Chenxuan was also amused, and immediately shouted with a smile.

"Come in, this king has been waiting for you for a long time."

"The prince is well." The three of them bowed their heads and greeted respectfully, very shy.

"How? The stuff you're studying. ”

Stuff, the three of my brothers researched, how can it be said to be a thing? The three were very unconvinced, but they did not refute either.

At this time, I saw the second child Zhu Jianghong carefully take out a package from his back, open the package, take out a fifty or sixty centimeter thing, and slowly pull away the wrapped strip of cloth, and a silver-white fire gun immediately appeared in front of Xiao Chenxuan's eyes.

Xiao Chenxuan rubbed his eyes back and forth, pinched his waist, and a pain came, and then he was sure that he was not dreaming, and immediately shouted.

"Talent, talent, you three brothers are really talents, like, too similar." Xiao Chenxuan was shocked, although he had never seen a gun in the real sense, but, as a senior construction mechanic, he had seen any shotgun and musket, and he once dismantled a shotgun and then assembled it back.

After receiving the praise of the prince, the three of them raised their heads and chests and became more confident.

Xiao Chenxuan picked up the gun and made an aiming posture, but the boss Zhu Lei snatched the gun from Xiao Chenxuan's hand.

"Lord Wang, be careful, this gun is filled with the stupid hat of the second child." Zhu Lei, the boss who took the gun, was afraid for a while, worried that the gun would injure the prince by mistake, and his family would be exterminated by the nine clans, and the second Zhu Jianghong lowered his head, like a child who was afraid of being beaten if he did something wrong.

"Gun lead, what is gun lead?" Xiao Chenxuan was very puzzled, it was the first time he had heard the new term gun.

"Lord, this gun is the name given by the three of my brothers, there is no gun lead, this fire gun" "It's not as good as a burning stick, with this gun will have a certain lethality." The boss Zhu Lei was very proud and immediately explained to Xiao Chenxuan.

"Huh? Lethality, how far can a gun be hit, and what can it kill? Xiao Chenxuan asked.

"Ahh How far to hit? I haven't tried this before, but it can kill a chicken, and the three of us brothers bought a lot of chickens in a row to test the lethality of this gun. ”

"Yes! Yes, can you show this gun to the king? ”

The second child immediately took out a small cloth bag from his pocket, and then took out a paper lump in the cloth bag, and after opening it, the original smell of gunpowder immediately rushed to the whole room.

"Gunpowder." Xiao Chenxuan's eyes widened, the gunpowder he had just thought of, he didn't expect these three guys to actually make the original gunpowder, although the power was 108,000 miles different from the black powder, it was feasible to make a salute or something.

"Lord Wang, do you also know about this thing?" The second child, Zhu Jianghong, immediately asked.

"I know, I know, since you can make this gunpowder, wait for this king to take you to study something more powerful, the kind that kills a cow with one shot."

"What? Kill a cow with one shot. The three brothers immediately opened their eyes wide and looked at Xiao Chenxuan in unison
