Zhou Nan nodded solemnly, for the Jin people who are now gaining momentum, if you want to say that the frontal hard fight, one is that the sacrifice is too great, and the other is that even if he wins Yanjing, with the strength and strength of Yanjing, to fight against the Jin army, it seems a little weak. Fighting hard head-on is definitely not what Zhou Nan wants to do.

For the Jin Army, which is at the peak of cold weapons, only hot weapons are used against them, even if they are hot weapons in the initial stage.

Now Lao Zheng Tou is completely convinced of Zhou Nan, Zhou Nan always makes a decision and then acts, and every move will show its effect in the things that follow, just like the 100,000 catties of sulfur this time. So when Zhou Nan talked about using bombs to deal with the Jin army, Lao Zheng Tou completely believed it, not to mention the previous few times he had the record of repelling the official army.

After the two finished drinking, they rested separately. Zhou Nan got up early, packed up the futon, and rummaged through the clothes. Gao Yun heard the movement, hurriedly came over to take a look, and asked, "Isn't Da Lang going to live in the village for a few days?" Why travel far? ”

Zhou Nan said while looking for clothes: "When I came back yesterday, I already told Guo Xingzu and others that I would move to live in Nanshan Village, and wait for the bomb to come out." By the way, remember to bring food every day, otherwise you will faint from hunger. ”

Gao Yun hurriedly sent Zhou Nan away and said, "The meal has been prepared, you can come back every night to live, why bother moving in like this?" ”

Zhou Nan said: "This matter is not trivial, it must be guarded, the slightest negligence will hurt people or even kill them." ”

Gao Yun heard what Zhou Nan said so seriously, she didn't dare to say more, prepared the bedding, let Zhou Nan eat, and said: "The slave family goes over to deliver food every day, and the change of clothes will be brought to Da Lang." ”

Zhou Nan hurriedly ate a few bites, and then took the futon to Nanzhai.

Guo Xingzu, Cai Xianzhong, and Zhu Xian, the three craftsmen, and more than 20 selected workers are already waiting. Lao Zheng Tou was indeed at a distance of thirty zhang from the sulfur warehouse, surrounded a fence one zhang high, and there was a only entrance and exit on the fence, which was the gate. In the open space not far from the gate, a row of wooden houses sitting north to south was built, the inside of the houses was spacious and bright, and there was a window on the north wall of the house, which was no worse than the stone houses of the village on the north side. At this time, Guo Xingzu and the others had already looked for rooms to live in, one for the three workers, one for Guo Xingzu, and there were two empty rooms, so Zhou Nan picked one and lived in.

Zhou Nan saw that everything was cleaned up, so he asked Guo Xingzu to take more than 20 workers into the sulfur warehouse, let Guo Xingzu operate it himself, and let these workers watch from the side. According to the formula given by Zhou Nan to Guo Xingzu, take out a little bit of sulfur and saltpeter in the warehouse and start grinding powder. The saltpeter with low purity will continue to be purified, and the specific operation will be taught by Guo Xingzu to these workers.

As for the charcoal, it was handed over to Cai Xianzhong and Zhu Xian. The sulfur warehouse was in the southwest corner of the village, and Zhou Nan led the two to the northeast corner of the village, which was a hillside, and Zhou Nan said to the two: "You two should burn charcoal first, and then arrange someone to burn charcoal later; You two will need to do your job. ”

Cai Xianzhong asked: "I don't know whether Dazhai is mainly made or cast?" I can do both. ”

Zhou Nandao: "You need to make iron pipes - but not yet, now it is to be cast, I will go back and draw a picture to show you." You can now burn paper charcoal and build your stove at the same time. ”

Cai Xianzhong and Zhu Xian have long wanted to use their own craftsmanship to contribute to the cottage, and now they heard Zhou Nan say that they would give them a pattern and ask them to cast, so they agreed and immediately began to build a kiln to burn charcoal. Of course, the blacksmith knows how to burn charcoal, which is related to the heat during smelting, so it is a bit of a waste to have these two blacksmiths burn charcoal.

The meal was indeed delivered by Gao Yun, but it was the first time it was delivered, and it was blocked by the cavalry under Zhou Nan. From today on, Zhou Nan will let his cavalry be on duty on the wall of Nanzhai, and no one is allowed to enter or leave. So although they knew that Gao Yun and the others were here to deliver food, the soldiers on duty still ran to report to Zhou Nan.

Zhou Nan personally went to the door of the house and asked the soldiers on the wall to bring the food in, and the female companion who followed Gao Yun was still huffing and said: "Wait for the meal to be delivered tomorrow night, see if you still say that you don't know our female village master." ”

Zhou Nan hurriedly smiled and apologized, it must be that these soldiers he brought back didn't know how powerful they were, and provoked these female "mountain kings", the female companion naturally didn't dare to accept Zhou Nan's courtesy, and ran back to Gao Yun with a smile. Zhou Nan turned back to the soldier on duty and said, "Look carefully, these sisters must be polite when they come over in the future, otherwise, be careful of starving you." Although Zhou Nan was joking, these soldiers were serious and replied in unison: "Yes!" ”

Zhou Nan waved his hand to let Li Feixing, the head of the capital guarding the wall, be selected from the recruits in Zhuozhou, who was calm and capable, and said: "You don't know many people, remember in the future, her," Zhou Nan pointed at Gao Yun with his hand and said, "It's the big village master here, and her words are my words." ”

Li Feixing said in a deep voice: "The villain has written it down!" Zhou Nan said again: "Tell the capitals that in the future, they will send someone to the back mountain to bring the food back, and don't send it to the owners of the village." ”

Li Feixing responded again, and Gao Yun saw that Zhou Nan was considerate of them, smiled slightly, and went back with a few female companions.

Zhou Nan went back and forth between Cai Xianzhong and Guo Xingzu's workshops to see if there were any problems that needed to be solved. In the second half of the morning, Guo Xingzu reported to Zhou Nan that 50 catties of sulfur had been ground and 30 catties of pure saltpeter had been ground, which was enough to prepare gunpowder. Zhou Nan asked Guo Xingzu to give these workers

Guo Xingzu was worried that Zhou Nan was in a hurry to use it, so these were made by himself, and after reporting to Zhou Nan, Guo Xingzu began to divide these workers into six groups according to Zhou Nan's requirements, one group burned paper charcoal, three groups were sulfur, saltpeter, and charcoal grinding powder, and one group was dispensing, and one group was charging. Two to three people per group.

Except for the group that burned paper and charcoal to find Cai Xianzhong, the remaining five groups, Guo Xingzu began to command everyone to build their own workshops first. Each workshop is located both away from the sulphur reservoir and separated from the others. Fortunately, the area enclosed near the sulphur reservoir is large enough to build their own workshops.

While Guo Xingzu was teaching these workers how to operate one by one, Zhou Nan went to Cai Xianzhong with the drawings he had drawn and an arrow.

Zhou Nan's paper is painted with a spindle-shaped oblong object, one end is large, the other end is small, the big end is also on the top of an arrow-like conical spike, and the small end has a finger-thick hole behind the tail.

Cai Xianzhong took the pattern and understood it at a glance, but he didn't know what the arrow Zhou Nan was holding was for.
