The head of the firm took over with a bright eye and praised Surdak very humbly.
"You are a generous knight!"
……
For several days, Surdak went to the foot of the village to set up a marching tent.
Then it was followed by driving everyone away, and even he blessed himself with a blessing.
The most important thing here in Walvillage is charcoal and sulfur. Prepare carbon powder and sulfur powder. At last, Surdak will prepare black powder outside the marching tent. It seems that he is alone. He is still carrying the magic note with him. Celia Cooper accompanied Surdak to introduce him to the basic knowledge of various glassware magic drugs.
Suldak poured some charcoal into the cup and filled it with sulfur while stirring. Until the last step, a certain proportion of nitrate powder was filled.
Suldak has done this modulation process for dozens of times.
The fact is that even if we know a little about the formula of black powder, it is not as simple as we thought. The powder is debugged and it is more like a group of fireworks that can explode with a strong flame. Even if parchment is tightly tied into a cylinder and the ends are blocked with yellow mud, this large firecracker still has no power.
"Are you sure you want to match it like this?" Celia Cooper saw Surdak repeating the previous practice and couldn’t help but vomit a way to him in the page.
Surdak wiped her apron and said to Celia Cooper seriously
"I don’t know what’s wrong, but I know it should be almost successful. This thing is not magic. This thing is more like Heicks science and technology. If it is really classified from academics, it should be physical chemistry."
He is still full of affection for Celia Cooper.
On what knowledge to ask Surdak, I can always hear some suggestions from Celia Cooper.
Celia Cooper had a strange look in her eyes, and she whispered behind the black fence on the page with one hand, "I find that I can’t understand you more and more."
Surdak stopped what he was doing and said to Celia Cooper, "What’s the matter? I can make black powder because … I got the formula for making black powder! I just don’t know that a small detail didn’t bring this thing into full play. "
Celia Cooper curled her lips and said to Surdak, "I don’t mean this troll pharmacist. I’ve seen many of them. I’m not interested in potions. I mean, what do you do? You build such a large reservoir in Woer Village without giving the land to knights. It’s not as simple as building a house and investing so much. What do you want?"
Surdak bowed his head again and said, "I am fulfilling my promise …" while stirring gunpowder in his hand.
By the time Rita delivered dinner to Surdak in the evening, Surdak had discovered a small drawback and made some improvements.
There was a gorgeous fireworks display on Surdakrita outside the tent.
Rita couldn’t speak for a moment, but she kept regretting, "It’s a pity that Natasha and Little Peter don’t …"
……
Boom’
A loud noise blocked the limestone in front of the river and was blown apart.
A group of kobolds have built artificial canals and embankments, looking at the river with a frightened face. The huge limestone is not blown apart, but the grave is bulging and full of cracks.
It was also Suldak who tested the amount of black powder after dozens of experiments.
At the end of the explosion, a group of kobolds and slaves walked gingerly along the river bed. They swung their picks to dig loose stones. Two kobolds joined forces to lift these rocks to the shore dam with a wooden stick. Several masons were building a low flood control dam with these stones, and the cracks in the stone walls were filled with volcanic ash mud.
With gunpowder road, the two biggest obstacles in this river were finally leveled by explosives.
Hundreds of kobold slaves rushed to the riverbank at the same time. This land is like a silent drum. After nearly a month of captivity, these kobold slaves can eat two full meals every day. Although the labor intensity here in the artificial canal construction site is a bit high, it has not affected the recovery of these kobold slaves. They all become very strong.
A lot of gravel came back from the bottom of the river, and the kobolds and slaves didn’t need to rest and clean up this section of the river.
They are just afraid of the loud noise, but they are almost familiar with it these days …
