As Chen Qi grew up, in order to train him, his mother handed over all the projects he made himself to manage, so Chen Qi became busier every day.

"Is there anything else that needs to be dealt with quickly," Chen Qi asked, "I promised my mother to go home today." ”

"Yes, there is also a question about the sale of 'Burning Knives'," Xiao Xiang'er replied, "Someone from the Luoyang family said that last year, the northern barbarians suffered a white plague, and many cattle and sheep died, and the sales of soju were greatly affected, so they wanted us to make a profit. Also, now the Red Turban thieves in the Central Plains are in trouble, and the transportation is very unsafe, so let's sell them the recipe for winemaking, and they are making wine in the north, which is close to the distance and reduces costs. ”

The name of distilled liquor "Burning Knife" is Chen Qi's bad taste, anyway, they are all sold to the northern barbarians, they are all big and coarse, and the simpler and more straightforward the name, the better.

"Hehe," Chen Qi sneered, "Some people are just not greedy enough, fighting rice and increasing hatred, do these people really treat me as a child? It is common for barbarians to suffer from snow disasters, but they are not willing to wait for death, there is no need to guess, I also know that the north must have been invaded by barbarians this spring, these barbarians have robbed so much gold and silver treasures, will they have no money to buy wine?"

"What a red turban thief, the red scarf thief is already a grasshopper after the autumn can't reach a few days, besides, our goods are transported by sea, through the big river to Luoyang, the red turban army along the coast has already been cleaned up, they just look at me as a child, want to cheat the formula. Chen Qi said angrily, "This is the third time, since the soju has been on sale, they always find excuses to ask for recipes, and they are not ashamed to be rejected so many times, but they are like flies, endlessly." ”

Although Lingnan is located in a remote area, there are official reports from time to time, and there are not many merchants in Jiangnan and the Central Plains, so the news is not closed.

Although the Red Turban Army Uprising was caught off guard at the beginning of the Great Liang Dynasty, many cities were captured, and the Red Turban Army was very arrogant in the first year of the uprising, but soon, the imperial court dispatched the northern border army into the Central Plains, and they fought against the barbarians all the year round, and their combat effectiveness was very strong.

Most of the millions of Red Turban Army were a rabble, vulnerable in front of the powerful Northern Army, and were quickly defeated. However, the leader of the Red Turban Army was very strategic and knew that he could not go head-to-head with the imperial court, so the large army was disbanded, the city was abandoned, and he began to enter remote villages and mountainous areas to continue fighting.

Quite the strategic style of Taizu's rural encirclement of the city in the previous life, but he did not have the luck of Taizu, the natural disasters in the Central Plains and Jiangnan passed quickly, and the Liang court was not completely decayed, and the grain from Guanzhong, the north and Shuzhong was mobilized into the Central Plains and Jiangnan for relief, and the society quickly settled down, so the Red Turban Army could only survive for more than three years.

More than a month ago, there were rumors that the leader of the Red Turban Army had died of illness, and it was estimated that the day of defeat of the Red Turban Army was not far away.

"Little Master, how do I reply to them?" asked Xiao Xiang'er.

"Don't worry about them, this is Lingnan, they can't make any waves," Chen Qi said, "By the way, there should be many merchants in the Central Plains who are interested in our soju, right?"

"More than a dozen large merchants in the Central Plains are very interested," Xiao Xiang'er replied.

"Okay, you ask Xiao Jia to come forward to contact a few companies, negotiate the price, and supply them too, eggs can't be put in the same basket," Chen Qi ordered.

After Chen Xiaojia became literate, he was found to have a very good talent in arithmetic, and it was too condescending to be a small follower, Chen Qi let him out, and now he is a shopkeeper of Chen's firm, and the big shopkeeper of the firm is his mother's person, she is not worried about her son, so she sends someone to take charge.

"Yes, young master. ”

"No," Chen Qi suddenly thought of something, "Those people won't be so stupid, you send someone to tell the steward of the wine workshop to pay more attention to the secrecy of the workshop, and prevent them from jumping off the wall in a hurry." ”

"Understood, little master," Xiao Xiang'er said with some hesitation, "they still want to ......"

"Don't ramble, what else do they want?" Chen Qi frowned, he was very tired of those people's insatiable greed, and he regretted that he took the initiative to contact his family in the first place, otherwise those people thought that Lingnan was a wild place, and there would be no such at all.

"They want to... I want the formula of the fairy earth," Xiao Xiang'er was a little scared, she knew that the little young master was angry.

"What?!" Chen Qi was furious, and slapped the small table in front of him, with a click, the small table split in half, "No, how did they know about the fairy soil, and they knew that it was produced by our family?

"Little young master, what are you talking about," Xiao Xiang'er was a little speechless, "Now the immortal soil and young master, your name is well-known in Lingnan, and most of the big families use our family's immortal soil, just inquire a little carefully." ”

"Uh," Chen Qi touched his forehead, "Okay, I'm confused, what is the yield of immortal soil? If there is any leftover, sell it to them, it's impossible to get the formula." ”

"Since you found new raw materials, the yield of fairy soil has increased significantly, and now nearly half of the land in Lingnan uses your fairy soil, and all of them have a bumper harvest, and the people of Lingnan are grateful to you and the master, saying that you are the star of Wenqu came into the world, and you will definitely be the champion in the future. Xiao Xiang'er's words were full of respect and adoration.

"Hehe," Chen Qi smiled faintly. He remembered the faces of those people.

When the next year, the news of the Chen family's grain harvest spread out, causing a sensation, but most people were skeptical, hesitant to wait and see, some big families suspected that the county guard Chen Shou deliberately created auspiciousness, hoping to return to the court with this, many people had done this kind of thing before, coaxing the emperor to be happy. Everyone just secretly sighed that Chen Shou had fallen, and he was no longer the outspoken scholar who was the original doctor, and in order to be promoted, he learned to flatter.

But in the second half of the year, the Chen family once again spread the news of a bumper harvest, some people couldn't sit still, and secretly sent people to the Chen family to investigate, and found that it was the truth.

But Chen Shou denied it, there is no fairy land at all, it is all rumors, everyone has no way but to go, but he is saying strange things behind his back, what the Chen family is too lonely, and he has been blessed by the gods, but he is unwilling to benefit the villagers and the elders;

Chen Shou can't help it, because the raw materials are insufficient, the output of soil compound fertilizer is very small, and the Chen family is not enough to use it.

Among the three kinds of raw materials, there is no shortage of manure, but although fish offal and plant ash are not valuable, they are very troublesome to collect, and the quantity is limited, it is difficult to obtain a large amount, and the most important thing is that if the Chen family collects it with great fanfare in the province, others are not stupid, and it is likely to guess the formula, so there must be a large number of stable and hidden sources of raw materials in order to expand production.

Chen Qi was very anxious about this, and tried to search and recall the memories of his previous life, remembering that compound fertilizers were synthesized by chemical reactions using ores containing nitrogen, phosphorus and potassium, but unfortunately he was not very good at chemistry, and he had never seen phosphate rock or potassium ore at all.

No, Chen Qi suddenly remembered that he happened to see in a popular science book that potassium ions mostly coexist with sodium ions in their natural state, forming potash ore, which is commonly known as bitter salt ore. So he sent people to inquire about the merchants from other places, but some people heard that there was a bitter salt mine somewhere.

Fortunately, a merchant from Shu said that there are several bitter salt mines in his hometown, but bitter salt is slightly poisonous, and eating too much is not good for the body, only those poor people eat it, and some unscrupulous salt merchants will sell bitter salt as salt, but the price is not high.

Overjoyed, Chen Qi immediately sent people to Shuzhong to bring back the samples of the bitter salt mines, and then used a few pots of flowers and trees for experiments, most of the flowers and trees withered, and only one pot grew more vigorously, which was obviously the potash ore he was looking for.

Although Shuzhong is very far away from Lingnan, but down the river, and then transfer to the sea, the transportation is still very convenient, so the Chen family bought the potash mine, the problem of potassium is solved, but the phosphate rock is not easy to find.

The only clue is that Chen Qi vaguely remembered that the phosphorus ions were pale green or pale cyan under the flame reaction, and he didn't know if it was right or not, so he had no choice but to send people all over the world to burn stones and bring them back with a similar light. Grandfather Chen Shou also issued a heavy reward in the name of the government.

However, after searching for more than half a year, I found a lot of stones that emitted pale green or pale cyan under the flame reaction, and after experimental verification, none of them were phosphate rock.

One day, Chen Qi, who was in a depressed mood, went to the street to play, and when he was tired, he casually entered a restaurant to eat, when the conversation between two foreign merchants next to him caught his attention.
