A year later, someone asked the Marquis of Tongyu, "How did you feel when you first saw Cai Anzhen?" The Marquis replied, "Beautiful, very beautiful." But he then added, "However, if you talk to Cai Anzhen for half an hour, you will forget the beauty of jì Yi, and even forget the beauty of jì yina." ”

Yes, when Xiahou Huan first saw Cai Ji, he only felt that the other party was a bright and moving girl. The no-makeup face that doesn't apply powder is neither pretentious nor aggressive. It is difficult to associate it with the majestic Longkou Commercial Port just now. However, the group of armored cavalry behind the girl, as well as the respectful attitude of Duan Rong, Zhen Yao and others, clearly showed that what happened in Donglai was from the hands of the delicate woman in front of her.

Let's say that Xiahou Huan sighed secretly in his heart. Cai Ji himself had already turned over and dismounted, and greeted a group of people and others, saying that Anzhen was late, so that the monarchs had waited for a long time. ”

"I've seen Cai Fujun." After Zhen Yao, Wang Han and the others hugged their fists and bowed, they then got up and laughed at Cai Jilang, "We have just arrived in Huang County. Bo Ming had only led us to see the Longkou Commercial Port before. ”

"Oh? Bo Ming has taken Zhujun to the commercial port? Cai Ji heard that Zhen Yao and others had visited Longkou Commercial Port, so he turned around and asked, I don't know what you think?"

After Zhen Yao and Wang Han glanced at each other, they praised in unison that it is indeed the largest port in the north! ”

If Zhen Yao and Wang Han were to collapse the Longkou Commercial Port as the first port in the world, Cai Ji would also discount them to think that they were flattering. However, since these two said that Longkou Commercial Port is the largest port in the north, then she accepted this evaluation with peace of mind. After all, Cai Ji still has this confidence. Now that he has been affirmed by his partners, Cai Ji asked while the iron was hot, "Then I don't know when you will ship the goods?" It must be known that the merchant ships of Donglai have been waiting here for a long time. ”

"Don't worry. Taiyue and I each brought a batch of goods to Huangxian this time, just to take the ship of Fujun to Dongwu to sell goods. Zhen Yao nodded in response.

"Oh? Taiyue brought a horse? Very good! The government happened to purchase a batch of war horses to equip the cavalry. As soon as Cai Ji heard about Arima sales, he immediately came to his senses. In order to expand the heavy cavalry, it is necessary to create armor and long knives, but the horses that are equipped with the heavy cavalry also need to be carefully selected.

Fortunately, Wang Han had regarded Cai Ji as a buddy at the moment, but he saw that he simply agreed, "Okay!" The fifty good horses brought by Wang this time were selected by the king. ”

"Brother Taiyue is really generous! Then you're welcome. Cai Ji stroked his palms and smiled. But at this moment, she suddenly glanced at a young man in a gorgeous costume hiding behind Zhen Yao. Zhen Yao and Wang Han have known each other for a long time, but Xiahou Huan is undoubtedly a new face to her. So Cai Ji couldn't help but ask Zhen Yao and the others curiously, "Who is this Lang Jun?" ”

"This is the Marquis of Tongyu, Xiahou Langjun." Zhen Yao turned around and introduced to Cai Ji.

And Xiahou Huan respectfully said to Cai Ji, "Xiahou Huan has seen Cai Fujun. ”

The Taishou of the two Han Dynasty was in charge of the military administration of one side and had always been the highest local governor. However, the power of the Taishou was too large and would inevitably affect the authority of the imperial court, so in order to strengthen the imperial power, the Western Han Dynasty began to set up the post of assassin to supervise local officials for the emperor. By the time of Emperor Ling of the Eastern Han Dynasty, Emperor Liu Yan changed some of the senior assassins to "pastoral" on the grounds of "eventful in all directions". As a result, the state pastor became the chief of the state military and government and the superior of the taishou, and the two-level system of state and county was also formed. However, after a few years of scuffle, most of the princes who are now really firmly seated in the state are from too guarded backgrounds, rather than assassins. It can be seen that in these troubled times, having soldiers and food is the last word. Therefore, even if Xiahou Huan has a knighthood on his head, he has to give three points to Cai Ji who is the Taishou at this time.

However, although Xiahou Huan's attitude was humble, Cai Ji couldn't help but be arrogant. What's more, the name of the Marquis of Tongyu appeared in the "Chronicles of the Three Kingdoms: Book of Wei". Thinking that it might be related to Cao Cao, Cai Ji politely returned the salute, "It turned out to be the little marquis." Disrespectful and disrespectful. ”

"Cai Fujun is polite. It is an honor to be able to see the style of Longkou Commercial Port today. Xiahou Huan said, raised his head with a bit of a businessman's sly smile and said, "Don't hide it from Cai Fujun, there is a batch of goods in your hands that you want to borrow precious treasures to get rid of." ”

Although Cai Ji didn't know that Xiahou Huan was doing business, as the so-called multiple roads, it was not a good thing to be able to catch the line of Tonghou Huan. Therefore, even if she is the head of the chin and the little marquis can appreciate the light, it is the honor of Longkou Port. ”

However, just when Cai Ji and Xiahou Huan were polite, a Duanfu servant suddenly ran from inside the city gate. At first, Duan Rong just happily watched Cai Ji talk about business with Zhen Yao and the others, but when the little guy muttered a few words in his ear, Duan Rong's face instantly turned pale. He first waved his hand to let the little guy wait beside him, then hesitated for a while, and finally gritted his teeth and came to Cai Ji's side and whispered Daofujun, Zhongmiao Courtyard has exploded. ”

As soon as Cai Ji heard that something had happened to Duan Zhi, the smile on his face quickly froze. Duan Zhi has been making gunpowder for her all these days, and Duan Rong has also known about it. It's just that the ancients had no idea about the power of gunpowder after all. Therefore, when he heard that the little maid came to report that there was a loud noise in the house, Duan Rong naturally panicked and hurriedly asked Cai Ji for help.

Although Zhen Yao and the others are not very old, they are all old rivers and lakes that have traveled from south to north. Seeing that Duan Rong and Cai Ji's faces became unnatural, they knew that something must have happened. As for what happened, they wouldn't be stupid enough to ask. No, Zhen Yaodang was tired even if he gave up his hand to Cai Jiyi smoothly and Dao Fujun all the way. It's better to go back to the house to rest first, we still need to pay some money, so we won't disturb the king. ”

"The government will take its leave." Knowing that the other party was looking for Cai Ji under the steps, he waved his long sleeves and said. Then she turned back to Duan Rong and instructed, "Bo Ming, you will be entertained by you." ”

Although Duan Rong was also worried about the situation in the Duan Mansion, he saw Cai Ji looking calm. I thought that my concentration could be worse than a girl, so I nodded my head and said. ”

Seeing that Duan Rong also calmed down, Cai Ji's heart was wide and he rushed to the accident site with the guards. But as soon as she entered the gate of Duan Mansion, she asked about the smell of gunsmoke, which was much stronger than the last time Duan Zhi fried the oven. Could it be that there was really a vicious explosion accident in Duanfu? Thinking of this, Cai Ji couldn't help but speed up the pace of his feet.

And as she walked, she didn't forget to ask the little guy who led the way, are there any casualties in the house? ”

"I don't know. As soon as the backyard exploded, the little one ran to find Da Langjun. The little guy replied with a smile.

"What about the old one?" Cai Ji frowned and asked.

"The master and the mistress went to the country." The little guy replied.

Cai Ji thought to himself that it was fortunate that Duan Kui Na Lao'er had gone to the countryside, otherwise such a big incident today would not have made him angry to death. But after all, Cai Ji still hoped in her heart that this was just a false alarm, because she had not seen any injured person carried out until now, although the further she went, the stronger the smell of sulfur became. Fortunately, Cai Ji had also been to Duan Zhi's workshop many times, so after a while, she came to Duan Zhi's courtyard with ease.

But he never thought that as soon as Cai Ji collapsed into the courtyard, the first thing that caught his eye was not a miserable scene of flesh and blood, nor did he show signs of explosion and burning. To be precise, there was nothing unusual in the courtyard except for a puff of blue-gray smoke. Seeing this, Cai Ji couldn't help but turn around and ask the little guy, "Where is the fryer?" ”

The little guy was so frightened by Cai Ji that he fell to his knees in the tunnel and spared his life. Small...... The little ones did hear a loud bang. Then there was a strange smoke rushing out of the courtyard. The little ones were so frightened that they went to Da Langjun. ”

Cai Ji also felt that it made sense when he heard the little guy's explanation, after all, in the era when fireworks were not popular, it was really scary enough to suddenly make such a loud noise. Could it be that Duan Zhi has a new variety? Just when Cai Ji was wondering, the sound of two men talking suddenly came from inside the workshop.

"Nakamiao, I didn't say it. According to this method, nitrate salt can be obtained by refining nitrate. ”

"Wonderful, wonderful, the nitrate refined according to Brother Zhengjie's method is really powerful."

Cai Ji listened carefully, one of them was naturally Duan Zhi, and the voice of the other person was also quite familiar. So she immediately raised her hand and sent the little maid away, and walked into the workshop. I saw that on the stove in the workshop, a cauldron was being set up at this moment, and Duan Zhi, who was dressed in a Taoist robe, was stirring it with a wooden stick while asking the young man next to him for advice. And that man was Lin Fei, a scholar and wealthy businessman who came to Donglai with Zhen Yao and others that day to discuss business.

Xu is Cai Ji's movement into the house alarmed the two who were experimenting, but they turned their heads at the same time. And after Lin Fei saw that the person who came was Cai Ji, he asked him with an innocent face, "Cai Fujun is here?" ”

Cai Ji thought to himself, I didn't scare the two of you. However, as soon as she thought of the conversation between the two just now, she pretended that nothing had happened, and stepped forward to respond that the house had heard that Zhong Miao had a new medicine, so she came to take a look. ”

"Brother Cai Xian came just in time. I am refining nitrate according to the method taught by Brother Zhengjie. Duan Zhi beckoned to Cai Ji like a child.

"Oh? Nitrate refining? Cai Ji looked into the pot, but there were only a few white crystals left in it except for a pot of muddy water.

"yes. Brother Zhengjie's nitrate salt is mixed with sulfur and ignited, and it is very powerful. Therefore, I begged him to teach me the method of refining nitrate. Unexpectedly, Brother Zhengjie taught him without saying a word. Brother Cai Xian, you see, we first crush the saltpeter, heat the water together with the ashes of the plants and trees according to eight to one, stir, filter, get nitrate, and then use a large pot to slowly boil this nitrate, and finally you can get nitrate. Duan Zhi triumphantly repeated the method that Lin Fei had taught him to Cai Ji again.

Cai Ji didn't know that the nitrate in Duan Zhi's mouth was actually potassium carbonate in later generations. But from the steps mentioned by Duan Zhi, it can be seen that he is purifying saltpeter. Lin Fei knows how to purify saltpeter? Why did he come to teach Duan Zhi this craft? Cai Ji knew that Lin Fei was not a person with a simple personality like Duan Zhi. After all, how can someone who can mix with Zhen Yao and other giant businessmen be a fuel-efficient lamp. What's more, until today, Lin Fei has not clearly expressed the purpose of coming out of Donglai like Zhen Yao and Wang Han. This feeling of being confused made Cai Ji very uncomfortable. So she immediately glanced at Lin Fei and said meaningfully, "I never thought that Lin Langjun still knew the way of alchemy. ”

"It's just an ancestral craft." Lin Fei bowed his head humbly.

Cai Ji saw that Lin Fei was still playing tricks, so he further tested him, "It turns out that Lin Langjun is a family scholar. Speaking of which, there are some alchemy issues in this mansion that I want to ask for advice, I wonder if Lin Langjun is free? ”

Lin Fei seemed to be waiting for Cai Ji's words, so after he asked Duan Zhi a few precautions, he raised his hand like a master and invited Cai Ji to say that this place is very hot, why don't you go to the study to talk? ”

"Good." Cai Ji nodded kindly, and then came to Duan Zhi's study with Lin Fei.

After the two of them sat down as the guest of honor, Cai Ji looked at Lin Fei, who was not alive at all, and asked, "It seems that Lin Langjun and Zhong Miao are quite familiar with each other. ”

"Zhong Miao likes tricks, so I have exchanged letters with me for a while." After Lin Fei lightly skipped his relationship with Duan Zhi, he followed up and asked Cai Ji rhetorically, "Fu Jun just said that he had something to ask Lin?" I don't know what's going on? ”

"Just ask about the nitrate just now. Nakamiao said that you mixed nitrate with sulfur and ignited it with great power. I wonder what happened? Why would the little guy in the house be scared to blow up the furnace in the courtyard. ”

"Lin used to just mix nitrate and sulfur one-to-one and ignite it. The sound is loud, but not powerful. In fact, there are many ways to mix nitrate, sulfur and carbon. It depends on whether it is flammable, explosive, toxic or tobacco. Lin Fei, who was talking eloquently, suddenly paused here, followed by Cai Ji and asked, "If I didn't guess that the recipe that Fujun gave to Zhong Miao seemed to want to explode." ”

Faced with the other party's questioning, Cai Ji nodded bluntly. The palace wanted to blow open the gates or walls with gunpowder. ”

"If so. Then Lin said bluntly, according to Fujun's prescription, even if he got a dozen catties of medicine, he couldn't blow up the city wall. Lin Fei struck unceremoniously.

"How so?" Although Cai Ji is very confident in black powder, the other party is also a professional in this era after all. It's always okay to hear what the professionals have to say.

Seeing Cai Ji's humble attitude, Lin Fei explained, "The prince doesn't know, any city in this world has weaknesses, and only by finding the weaknesses can the city be destroyed." Of course, if it is the gunpowder of the king, then it can get twice the result with half the effort. ”

Looking for a weakness in the city walls? Lin Fei's remarks reminded Cai Ji of a certain American drama he watched in his previous life. That is, the key stress points of the wall are calculated, and then the holes are drilled at the key positions, so that the load-bearing strength of the wall is reduced. Will an Eastern Han Dynasty understand Hooke's Law? This is obviously somewhat unreliable. However, Cai Ji has a school of thought in Chinese history that is particularly studied in siege.

Thinking of this, Cai Ji changed the conversation and said, "I heard from this mansion that Lin Langjun's family seems to have helped Dong Zhuo dig the grave. ”

"Tomb robbing is Lin's family education." Lin Fei nodded without scruples.

"But this house doesn't look like it." Cai Ji shook his head and said.

"What does that Fujun think Lin has learned?" Lin Fei asked noncommittally.

But seeing Cai Ji suddenly raise his head and look at the other party, he said word by word, if the mansion didn't guess, Lin Langjun's family study should be Moxue. ”
