"There's no need. This person is no threat to me! Zhang Qian shook his head with a smile, looking at the two junior brothers with eyes full of gratitude. Besides, you may not be able to kill him. He found you just when you arrived. ”

"We have in the front yard and we have reserved staff. "Guo frowned, and didn't understand why Zhang Qian had to show mercy to a character who was difficult to distinguish between friend and foe and who could leak secrets at any time....... If his father had stood in the same position as the senior brother, as early as the night of the shelling of the altar, the surname Luo would have been stuffed into a sack and sunk to the bottom of the Wei River, and this person would not have been left until now.

"Second Senior Brother, what Senior Brother said is that there is no need!" Ren Cong has been dating Zhang Qian for a long time, and he is far more sensitive to the changes in his body than Guo Nu, so he gently pulled the latter's stumbling armor and interrupted in a low voice.

"Not necessary?" Guo Nu turned his head, looked at Ren Cong with a puzzled face, and repeated in a low voice. Immediately, there was a burning light in his eyes.

The elder brother is soft-hearted, and there are even some indiscriminate people. This is clear to both him and Ren Cong. However, if tonight's events had been done before, the senior brother would have said, "Don't kill him", not "It's not necessary." Although these two sentences can achieve the same effect. But the speaker's mentality is completely different.

The former, just out of a good nature. The latter, on the other hand, reveals the ability to control the danger within a limited range.

"Let the brethren go back and rest, for you have had a hard time tonight. You two, settle down late brethren, change your clothes, and go to the study to find me, I have something for you! Just as he was surprised and delighted, Zhang Qian's words came into his ears again, and he still sounded full of confidence and calmness.

"Yes, big brother." Guo Nu and Ren Cong agreed, and hurriedly took the family members down to settle down. After a quarter of an hour of busyness, they each changed into their daily clothes and came to Zhang Qian's study. And their senior brother had been waiting in the study for a long time, looking at a concave sketch full of dense numbers, and the look of remembrance on his face was clearly visible.

"Big brother!" Ren Cong stood beside Zhang Qian and looked at the concave sketch for a long time, but he didn't understand what was written on it, and called out uneasily.

Guo Nu was sure that the senior brother was going to teach the new master tonight, and his face was red with excitement, and his eyes were as bright as candles. "Senior brother, I checked just now to make sure there is no fourth person around......"

Before he could finish speaking, the door was gently pushed open outside. Zijuan held the tea and snacks on a lacquer plate and walked in cautiously. "Shaolangjun, let's have some supper. It's all made by the handicap. ”

At this time, Guo Nu was immediately blinded. I want to drive the purple cuckoo away, but I am worried that I will be blown by the pillow in the future. If he didn't hurry, there would be a risk of leaking the secrets of the master's sect, and the cowhide he had just bragged about was really a little ugly.

Fortunately, Zijuan just came over to deliver tea and snacks, and after putting it down, he saluted Zhang Qianqian again, and slowly retreated. And Zhang Qian, who didn't seem to care much about the leakage, took a few sips of tea first, and then picked up the blank paper with the sketch and handed it to Ren Cong, "This one is for you." ”

"Thank you, big brother!" Ren Cong's nervous voice changed, he took the sketch with both hands and bowed to thank him.

"This one is for you, exactly the same." Zhang Qian smiled, picked up the second piece of white paper with a concave sketch drawn on the desk, and handed it to Guo Nu, "You two put it away first, and then find time to memorize it." This is one of the three mastery of the master, the advanced content of physics, about the composition of matter in the world. The division calls it the periodic table. ”

"Thank you, brother!" In an instant, Guo Nu's face was full of ecstasy, and his body trembled slightly because of excitement.

Senior Brother once said that Qin Mo has three great studies, philosophy, mathematics and physics. Philosophy can make people smart, mathematics can calculate everything in the world, and physics, learn the depths, and you can move mountains and seas and change the world with a wave of your hand!

Originally, he and Ren Cong thought it might be an exaggeration. However, on the day of the eclipse, he witnessed the senior brother send a huge altar and the monks in the altar to the western heaven with three bronze bells, at least a hundred paces away, and he and Ren Cong no longer dared to have the slightest doubt about the power of the master's peerless learning!

Three packets of black medicinal powder, three clay pots filled with medicinal powder, the two brothers helped rub the medicine twist, and the fire was also lit by their own hands. They had no reason to suspect that the situation was false. And it was precisely because of the participation in the entire shelling process from beginning to end that after the altar was shattered, the impact on the two of them was even stronger, so strong that the two of them dreamed for several days in a row, dreaming that they were carrying a fire-breathing bronze bell and killing all sides. As the bell pointed out, whether it is a god or a ghost, they are all gone!

And now, the senior brother is actually ready to teach the knowledge that changes the world and the world, let me ask, how can Guo Nu and Ren Cong not be excited? It's a pity that this feeling of excitement only lasted less than ten breaths before disappearing. In its place, there is a deep sense of frustration.

They could hear every word of what the senior brother said. However, only the first few words, the two of them could barely understand it, and the next one, it was like hearing the heavenly book!

"The world is material, and the material is not only the five kinds of "gold, wood, water, fire, and earth", but also can be subdivided, and the division has discovered 92 elements so far, all of which are written on the table in the hands of the two of you, and more can be found in the future. At present, these 92 species are classified by the division into seven main families, seven secondary families, the eighth family and zero ......" (Note: there are currently 119 species, and 92 is the number that can be found in nature.) ）

Leaving some time for the two juniors to be confused, Zhang Qian picked up the tea and poured it down. In just ten minutes of class, it was more tiring than the two intrigues with Luo Huaizu just now.

Although in another time and space, he studied at a normal university and specialized in psychology and teaching skills, but he found that he was really not suitable to be a teacher.

When I was in junior high school, the teacher talked about the periodic table, and it didn't take long for the whole class to hear it clearly. And himself, who had prepared the class in advance, actually stared at Guo Nu and Ren Cong, who were not stupid, with big eyes.

However, thinking about it, the amount of information that middle students were exposed to at the beginning of the 21st century in another time and space, Zhang Qian's eyes were full of sympathy when he looked at Guo Nu and Ren Cong.

In another time and space, I will carry a junior high school student in Huaxia Country at random, I am afraid that they are all accompanied by TV and the Internet, and they should master the knowledge that they should not master, and they rush into their minds like a tide from morning to night every day. In the eighth century, when the literacy rate was less than 10 percent, and most of the Confucian classics were read, people's understanding of the world almost stopped in the Western Han Dynasty.

However, Zhang Qian's sympathy is sympathy, but he is not anxious for Ren Cong and Guo Nu at all. Compared with junior high school students in another time and space, the amount of information they are exposed to is small, which is the shortcoming of the two. However, due to the fact that they have studied Confucian classics since childhood, they have all relied on rote memorization, and their memories have been trained to have the potential to be scholars. What they can't understand for a while, don't delay them to memorize it, and after memorizing it, it's not too late to learn and understand it in the "trial class"!

And for the trial class, Zhang Qian has long been prepared. Although the fine-mouthed glass bottles and curved neck retorts customized from the Liuli Wang's family cannot be made colorless and transparent, and the bottle is too thick, the paper strips used to demonstrate the lack of oxygen and the presence of oxygen can still meet the requirements. (Note: Ancient Chinese glass bottles have unearthed cultural relics, which were invented very early.) It's just that because of the price and quality issues, there is no popular opening. ）

As for the materials that are heated to produce oxygen, it is easier to find. Recently, Sun Anzu, who often came to treat Zhang Qian's wounds and drank wine for nothing, is Sun Simiao's descendant. There are not too many dansha, lead pills, and three elixirs hidden in this old family. In order to figure out the difference between these medicines, Zhang Qian also secretly did several heating tests, and finally found that the cheapest lead pill had the best effect, so he finally decided to choose it as the main material to demonstrate the existence of oxygen. (Note: Dansha is mercury sulfide, but when Taoist priests refine Dan, they can't distinguish between mercury sulfide and mercury oxide, so it's basically a mixture of two substances.) Lead pill is a mixture of lead peroxide and lead oxide, and the three elixir is mercury oxide mixed with other impurities. ）

Facts have also proved that whether it is in the 21st century in another time and space, or in the 8th century in this time and space, experimental courses are far more popular than theory courses. When Zhang Qian ordered Ren Cong and Guo Nu to put away the periodic table and copy the texts he had prepared and take them back to memorize, their mouths twitched into buns. And when Zhang Qian took out a small alcohol lamp, a glass bottle and a curved neck retort from the bookcase, the eyes of the two suddenly began to burn again.

The trial process was simple and the results were easy to accept. Especially when Zhang Qian corresponded oxygen with the yang, nitrogen and other gases that Taoists claim daily, and the yin energy that Taoists declare every day, Guo Nu and Ren Cong danced excitedly.

This time, the two of them understood without much effort. And, I vaguely felt the joy of revealing the secret of the composition of the world.

"Everything is in the study, and you two can come in at any time if you want to do it yourself. Just be careful not to cause a fire! "I am grateful to the two junior brothers for coming to the rescue in time tonight, and at the same time, I also remembered the request made by the two of them a few days ago to give their respective families guidance on how to make money. Immediately, a small iron pot, a funnel and a large bowl were taken out.

"The next thing I'm going to teach you to do is called coarse salt purification. After learning this trick, you will find that the expensive green salt on the market is easy to make. While speaking, Zhang Qian instructed the two to do it, and melted the black, dirty, and sand-mixed coarse salt of the official sale into the water. Then he instructed the two to use arrowroot cloth to repeatedly filter out the impurities in the salt water, until the salt water was almost as clear as cold water, and then put it into the iron pot.

。 When Guo Nu and Ren Cong lit the alcohol stove with their own hands, they watched as the salt water in the iron pot was steamed dry, and finally turned into a pile of pure white powder. The two of them were so excited that their fists clenched, and the green tendons on their foreheads jumped wildly

In Datang, green salt with excellent quality has always been sold as a luxury product. Even the Ren family and the Guo family only dare to use it to brush the teeth of the owner of the family, and will not use this thing to stir-fry. But today, the two of them have personally turned the coarse salt sold by the government into a luxury item whose quality is far better than that of green salt! (Note: Green salt, the crystalline salt of Qinghai first-generation salt minerals.) Because the content is pure and the taste is good, the price has always been high. ）

The salt officials of Datang sell it, and private individuals are not allowed to touch it. But both the Guo family and the Ren family have enough ability to buy coarse salt in large quantities. After refining coarse salt and selling it as a luxury product, not only can it bypass the monopoly ban on salt and iron, but the profit it can obtain will also be a frightening figure.

"You can teach this to your families. As for how the elders in the family make money, don't mix with the two of you. Zhang Qian saw Guo Nu and Ren Cong's expressions, and he didn't feel much surprised, smiled, and reminded in a low voice.

"Really?" Guo Nu and Ren Cong couldn't believe their ears. The questioning words blurted out.

When I saw Zhang Qian, he nodded lightly, and there was no regret on his face. The two of them released their clenched fists, and the whole person crouched beside the alcohol stove as if they had collapsed.

"If you remember it, if you don't remember it, just do it again yourself!" Zhang Qian gave a thoughtful admonition, turned his head, and began to wash his hands and tidy up the stall, ready to rest. "If you don't understand, you can ask me at any time!"

This means of making money is actually much simpler than toilet water. However, he had not had the courage to show it before. There is no other reason, there is not enough strength, but to get involved in the salt trade, which is equivalent to looking for death.

And now, his flower water business has gradually stabilized, and with his status, it is not so easy for others to snatch the Six Gods Trading House away. Salt purification, which requires too much political resources to make money, is very chicken for him.

Therefore, Zhang Qian didn't do it himself, but through the two junior brothers, he transferred this idea to the Guo family and the Ren family, which was the most suitable.

First of all, the Guo family and the Ren family, or the Guo family and the Ren family, have enough strength and political resources to resist and resolve the risks brought about by the purchase and sale of coarse salt purification.

Secondly, in the conflict with Buddhism some time ago, although the Guo family and the Ren family did not openly stand on his side, they did not hinder Guo Nu and Ren Cong from bringing the family to help, and this kindness is worth reciprocating.

Finally, on the basis of the current happy cooperation between the two parties, Zhang Qian is willing to let the two families have one more shortcut to make money, and then bring the relationship between them closer. In this way, when Zhang Qian himself encounters trouble in the future, the motivation of these two families to help will be more sufficient.

"Filter again, although Senior Brother also let us filter it three times just now, the color of the water is clearer than this time!"

"I filtered it three times just now, and I'm afraid it's going to add to it."

"Ding! While! ”

……

The sound of whispering and metal crashing sounded under Zhang Qian's feet. But Guo Nu and Ren Cong didn't dare to take it lightly, and before he left, they began to repeat the entire crude salt purification test process.

"Hmm!" Zhang Qian smiled and nodded easily.

As a teacher, he is not afraid of the slow response of the students, so he will be lazy and good-looking, and he will take it as if he does not know it. As for the motivation for Ren Cong and Guo Nu to be so serious and studious, he didn't care.

Both junior disciples were born in the family of merchants, and it was a strange thing that they could not see the interests hidden behind the coarse salt purification test. As for the distribution of interests between the Ren and Guo families, just like when they invested in the wind oil essence industry, Guo Nu and Ren Cong have a tacit understanding to deal with it, and they don't need Zhang Qian, who is a senior brother, to intervene.

However, this relaxed and comfortable feeling did not even last until the end of the second test, when it was disturbed by the sudden sound of footsteps in the yard.

'Who?' Guo Nu jumped up like a lion that had lost its food; Come, three steps and two steps to the door. Ren Cong, on the other hand, tacitly walked to the window and pulled the sword out of the scabbard.

The brothers and sisters share the benefits, and they can be polite. If a third person wants to snoop, they will resolutely deliver a fatal blow. Even when this person entered the inner courtyard, he did not alarm the geese in the courtyard.

"Guo Shaolangjun, it's me! Optional! The answer quickly spread into the room, making Ren Cong immediately breathe a sigh of relief.

However, the next sentence that followed raised his heart to his throat, "Is Ren Shaolangjun also in my family's owner's study?" His family sent someone to send an urgent letter, and the glaze workshop of the Liuli King in Xinfeng County caught fire, burning several guys to death, and the Liuli King himself was arrested in Xinfeng County! ”

"What?" As soon as the words fell, not only Ren Cong was in a hurry, but Guo Nu's eyes were also on fire, and he stepped forward and grabbed Ren Quan's arm, "What did you say?" How many things will be in time? Why did the Yamen of Xinfeng County arrest Wang Fugui? ”

"The glass king's glass workshop has exploded, just tonight. Why did the Xinfeng County Ya arrest King Liuli, it should be that a lot of guys died in the workshop, and I am afraid that he will not be able to explain to the bitter master after he runs away! Ren Quan gasped and responded quickly, his face was full of sweat.

It's no wonder that he panicked, as Zhang Qian's big housekeeper, he knows the production process of the six gods in Zhuangzi well. It is also a liquid that exudes a fragrance, and the Liushen Flower Dew can be sold more than ten times more expensive than the wind oil essence, and it is also flocking to it. The beautiful glass bottle plays a big role in it. At a glance with the naked eye, you can know that the contents of the bottle are very high-end, and they are by no means comparable to the wind and oil essence in the porcelain bottle.

And because the demand is not high, the glass bottles used by the Liushen Workshop to divide the flower dew have been exclusively supplied by the Liuli King. There are also strict rules about the style and size of the bottle. And now, the workshop of the Liuli King was burned to the ground, and the Liuli King himself was also arrested and imprisoned by the government.

"Don't panic first, our workshop hasn't been rebuilt yet, and it will be a matter of the next year if we want to put it into production." In the courtyard, the only one who still maintained his composure was Zhang Qian, the last one to come out of the study. stepped forward and gently patted Ren Quan's shoulder, smiling and comforting. "It's not difficult to make glass bottles, I really can't find anyone to provide them, and we can make them by opening our own workshop."

"Owner, do you know how to make glass?" Ren Quan was surprised and delighted, and the anxious look on his face disappeared in an instant. "That's good, that's good. Immediately, the roads and canals in the Zhuangzi were repaired, and a glazed workshop was opened, which was just enough for the villagers to have something to do. ”

"Senior brother, King Liuli is my friend. I have to go to Xinfeng to see what the hell is going on. Ren Cong's face did not show the slightest relaxed expression, and he saluted Zhang and made a solemn request.

Seeing that he could temporarily put aside even the benefits of coarse salt purification, Zhang Qian immediately understood the weight of Wang Fugui's friend in Ren Cong's heart. smiled and nodded slightly, "It's so late, you rush over now, and you won't see the Xinfeng County Order." It's better to find a way to send someone to the Xinfeng County prison to dredge it up, so as not to make King Liuli suffer inside. As for the bereavement guy and other aftermath issues, you will rush to Wang's house early tomorrow morning and come down for him first. Since he is one of the shareholders of our Liushen Commercial Bank, if he encounters trouble, the commercial bank can't ignore it! ”

"Yes! Big brother! Ren Cong's heart was in turmoil, but he knew that Zhang Qian's arrangement was more reasonable, thought about it, and nodded vigorously.

"Dredging the matter of the yamen, I'll send someone, I'm more familiar than you!" Seeing his unruly appearance, Guo Nu didn't care about continuing to toss the coarse salt for purification, thought about it, and whispered next to him.

After that, without waiting for Ren Cong to respond, he quickly turned his head to Zhang Qian, "Senior brother, King Liuli is a talent, even if he doesn't survive this time, the business will collapse." It's worth spending some effort to pull him along. ”

"Okay! You two will discuss it! Regarding the specific operations in the business field, Zhang Qian thought that he was not as good as Guo Nu and Ren Cong, and nodded with a decisive smile, "If the Liuli King hasn't done anything bad, his reputation is still passable." When needed, I will also play my signboard, Xinfeng County Ya, maybe it will give me some face! ”

"Thank you, brother." When Ren Cong heard this, he finally had a smile on his face, and he couldn't wait to give Zhang Qian a salute.

"I know Senior Brother Xie, my second senior brother deserves to work for you, right?" Guo Nu immediately became jealous, pushed Ren Cong, and protested in a low voice.

"Thank you, Second Senior Brother." Ren Cong couldn't cry or laugh, so he had to thank him again. When I straightened my waist again, the anxiety in my heart was dispelled a lot.

The brothers did what they said they would do, and immediately went their separate ways. Originally, I thought that it was just a simple workshop fire, as long as Wang Fugui, nicknamed the King of Liuli, was willing to pay to compensate the families of the guys and get this person out of prison, it shouldn't be too much trouble. In the end, Guo Nu was helpless, and simply moved out of his father Guo Juxian to come forward to vouch, only to reluctantly let Xinfeng County Ling Wang Zude relax, but forced the Wang family to leave 3,000 hanging bail, so as not to abscond Wang Fugui from committing crimes.

And Wang Fugui himself, although he did not suffer any major crimes in prison, was also tossed to the bone. After getting into the carriage specially prepared for him by Ren Cong, he immediately "poofed" and collapsed in the carriage. Under the call of his wife and children, this person finally relieved his breath for a long time, and then ordered someone to stop the car, and chased him in front of Ren Cong and Guo Nu, who were escorting him home on horseback, and knelt on his knees: "Second brother, Xiao Wu, I dare not say thank you, in the next life, Wang will be a cow and a horse, and I must repay you!" ”

"What do you say, Fat Wang! Who is with whom of our brothers, do you still need to be so polite? "Ren Cong and Guo Nu have not been officials for long, and they have not gotten rid of the smell of gentlemen. Seeing that Wang Fugui actually made such a big gift, he hurriedly jumped off the horse with a smile and supported him.

"I'm not going home, second brother, Xiao Wu, please send me to Jingzhao Mansion, I want to sue Xinfeng County Order! The workshop was not burned down at all, he arrested me just to shield the arsonist and give him a chance to escape! Wang Fugui refused to get up, gritted his teeth, and tears fell like rain, "I don't want the workshop, and the rest of the family wealth is enough for my wife and children to live." I'm fighting with my life to get justice for myself and my guys! ”
