After Qi Ye demonstrated the power of mosquito coils, he looked at the owners of several incense shops who were quite familiar with him with a smug expression. Those people looked at the stiff mosquitoes on the ground, and carefully savored the smoke of mosquito coils that had dispersed. One of them asked puzzledly, "Brother Qi, how much realgar is mixed in this incense of yours!" How much arsenic is adulterated? ”

In an instant, Qi Ye's expression changed from smug to embarrassed. The power of this mosquito coil was so great that Qi Ye had to be shaken by this inquiry.

The other incense makers looked at Qi Ye's embarrassed expression, and their expressions became solemn. The Great Song Dynasty already has mosquito coils, during the Dragon Boat Festival, collect and store duckweed, dry in the shade, add realgar, make paper to wrap incense, burn it, can get rid of mosquitoes. Realgar is an arsenic sulfide ore and a widely used pesticide in ancient times. Incense makers who are proficient in dispensing will also mix a trace amount of arsenic in this incense, which can play a very effective role in expelling mosquitoes.

Thinking of Zhao Jiaren's appearance standing in the smoke, Qi Ye also had some courage to refute. If he really relied on adding these poisonous things, Zhao Jiaren didn't need to risk himself. Thinking of this, Qi Ye took out a bag of powder, "You and the others are all connoisseurs, I see that you brought a guy who makes incense." You have tested these powders yourself, and then you have made them into incense, whether they are useful or not, you naturally know. ”

An expert is an expert, and he is not in a hurry to do it after getting the powder. Some people have a sensitive nose, so they sniff the powder. Some of them have a keen eye, so they come to the front of their eyes to take a closer look. Some believed in Qi Ye more, so they pinched a small pinch and put it in their mouths to taste. After several people judged it, they all thought that this thing was a natural plant and had not been specially processed.

Looking at the group of serious working experts, Qi Ye made tea for himself and tasted it slowly. When he was just now, he was almost blindfolded by these people, but fortunately, Qi Ye was firm enough. At this time, Qi Ye had the upper hand, and said calmly while eating and drinking: "Don't dry these medicinal powders." If the fire is big, I am afraid that it will lose its effect. You just care. ”

Zhao Jiaren explained not to use the traditional heating method. He was worried that the lipids in pyrethrum would be hydrolyzed by mixing them with water and then heating them. Qi Ye didn't know why, so he still told the incense master what he needed to pay attention to. The masters didn't ask after hearing this, they are experts after all, and many spices can't be processed with high fire. Otherwise, the aroma will escape.

Compared to that, mixing medicinal powder to make incense is just a drizzle. After working for a while, everyone made a preliminary incense piece with saltpeter powder. After drying in the shade for a while, there was a higher level of modulation of dry and wet properly, and I found another room to try. The smoke passed, and the mosquitoes stiffened.

Seeing that some people have already finished it, others can't care so much, so they will also take out their own products and try them. The effect is good and bad, and the insecticidal power is not very different.

Qi Ye looked at the guys with uncertain expressions proudly, and thought about the conversation with Zhao Jiaren in his heart.

"Brother Qi, if you come to sell this powder, I don't think you will tell others where you got it, right?"

"That's up to you to give me."

"How much do you want?"

“…… Twenty-eight accounts. What does Brother Zhao think? ”

Zhao Jiaren is a promising official, and as a clan relative of the Zhao family, Qi Ye really doesn't want to offend. Only dared to ask for two percent, even if it was only two percent, it would make Qi Ye earn enough. Zhao Jiaren said that next year will try to get tens of thousands of catties. With tens of thousands of catties of this powder, the mosquito coils made can probably be sold all over Guangdong Road, Zhejiang Road, Fujian Road, and Lianghuai. It can even be sold to Mongolia. Even if a pound of powder is only sold for two guan, 10,000 jin is 20,000 guan, and Qi Ye can earn 4,000 guan without much effort. The Song Dynasty had a saying about the wealthy, and the family was rich.

Zhao Jiaren did not participate in such a thing, he originally wanted to produce and sell it himself, but after recommending it for a few days, he suddenly realized. There is nothing wrong with this thing as a personal gift, but as a commonly circulated commodity, it will face market skepticism. Rather than monopolizing their own inefficient interests, it is better to borrow the mature channels that the incense shop already has to make money in a short and fast way.

After determining this, Zhao Jiaren handed over all the intermediaries to Qi Ye, and he went to Zhou Qing's blacksmith shop by himself.

Zhou Qing saw the owner coming, and introduced the situation with some trepidation, "The shop hasn't made any money recently. ”

"As soon as it opened, where you could make money." Zhao Jiaren comforted Zhou Qing happily. After speaking, he asked, "Can you do what I told you?" ”

Zhou Qing didn't answer, he took Zhao Jiaren to the back and took out a small cannon from a wooden box. The length of this gun is more than 60 centimeters, the barrel is thin in the front and thick in the back, the caliber in the front is about 10 centimeters, and the diameter of the pipe in the back is about 20 centimeters. Zhao Jiaren looked at the thing cast by Zhou Qing with satisfaction, this thing was similar to the pound cannon in Zhao Jiaren's memory. A catty cannon refers to a cannonball projectile weighing one catty, with cannon lugs, with an iron brazing gun mount, mounted on both sides of the ship's side for shooting. It can fire both solid and scattered bullets. It was very popular during the Age of Discovery. Pirates of the Caribbean movies have been shot of this artillery several times.

"If this thing explodes, can you figure out the problem?" Zhao Jiaren asked casually.

After asking, he didn't hear an answer, Zhao Jiaren looked at it carefully for a while, and then he felt that something was not right. looked up at Zhou Qing, but saw him with a hurt expression. It can be seen that Zhao Jiaren's words made Zhou Qing full of negative emotions. Seeing Zhao Jiaren looking over, Zhou Qing said in a whisper: "Zhao Guanren, do you have to use the things I cast?" ”

Zhao Jiaren didn't know how to respond. Artillery explosions are not uncommon in the history of artillery, and Zhao Jiaren did not mean to accuse Zhou Qing at all. But it was impossible to be stunned and not speak, Zhao Jiaren smiled: "I love all kinds of attempts, in case this thing is broken, I don't know if Zhou Qing can see the reason." ”

"Hmm...... Since the things are handed over to Zhao Guanren, you can use them. Zhou Qing's tone was depressed, as if what was handed over to Zhao Jiaren was not a tool, but a child that Zhou Qing cherished. This attitude made Zhao Jiaren endure more than once.

Laughing and laughing, Zhao Jiaren couldn't help but think about it in his heart. He originally hoped that Zhou Qing would be able to make a prototype that would facilitate mass production in the future. Now looking at Zhou Qing's posture, Zhao Jiaren also has a reason in his heart. Once the news of this weapon leaks, the result is probably very bad. Zhao Jiaren and Zhou Qing have an advantage in that aspect, but Zhao Jiaren does not have the power to let Zhou Qing have to keep secrets. If Zhou Qing ran away with the diagram of the cannon casting, Zhao Jiaren could only stare dryly. Whether or not to let Zhou Qing know too much, Zhao Jiaren was undecided at this time.

A few days later, Zhao Jiaren went to visit Qi Ye. Qi Ye smiled and took the deposit receipt of 180 yuan and handed it to Zhao Jiaren. Zhao Jiaren didn't answer, he said: "Eighty Guan help me buy sulfur and saltpeter." Another hundred, and see if there are any craftsmen who can fix my boat completely. ”

The wrecked ship stranded in Fuqing County could already be repaired and sailed, but Zhao Jiaren knew very well that if it could not carry out a comprehensive overhaul, the ship would not be able to withstand too much wind and waves at sea.

"I'm afraid that one hundred runs won't work, but I have to go one hundred and eighty." Qi Ye replied.

Zhao Jiaren likes Qi Ye the most, no matter how much he helps, Qi Ye will not let himself lose money. A person who does not allow himself to lose money generally does not let the other party lose money. After receiving the 100 yuan of banknotes handed over by Zhao Jiaren, Qi Ye earnestly told Zhao Jiaren, "Next year, those medicinal powders should be sent as soon as possible." Brother Zhao, don't forget. ”
