Take a merchant ship to fish? It seems like a waste, but anyway, when the fish is sold for seventy yuan, the people who hear the news can't sit still. Pen ~ Fun ~ Pavilion www.biquge.info This ship can earn 30 yuan a day, nearly 10,000 yuan a year, and this ship will basically return to its original cost, and there is still such a good business in the world.

Of course, there is no such good business in the world, if there are too many people fishing, the price of this fish will definitely plummet, and it will be difficult to earn 30 yuan when the time comes, but it will be difficult, today these fish are mainly bought by large restaurants, and ordinary people often can't afford to consume. Tomorrow the fish may not be sold out.

But Zhao Zheng is not these fish, but two other species, seaweed and kelp. These two ships were prepared for the South China Sea trade later.

Seafood farming did not rise until modern times, and the Song Dynasty did not have this awareness and technology at all, but now the arrival of Zhao Zheng has made it up for them.

Seaweed seedlings can be successfully raised as long as about half a month, and then can be harvested once in about ten days, low cost, large yield, about 1,000 catties per mu, of course, with the current technology may not be possible, but seven or eight hundred catties are always there, ten days can be harvested once, mainly in winter and spring harvest.

The kelp is a little more complicated, the main harvest is in the summer, but the yield per mu is much higher than that of laver, calculated by tons, the later generations are generally in seven or eight tons, with the current technology is a little less than five tons, how to have, five tons is five thousand kilograms, that is, 10,000 catties. How many people will be scared at this time!

Sun He looked at the seaweed soup that Zhao Zheng had boiled, and he was also a little puzzled, can this thing be eaten?

In the shack, the prisoners also opened their eyes wide, but no one dared to ask, even if it was poison, they could only drink it.

Zhao Zheng served a bowl first, and drank it straight with the soup. Sun He saw that the little fairy chief drank it, so he also drank it.

When everyone saw that the two officials had drunk, they still didn't believe it, so they began to line up.

When those people ate the nori in their mouths, their eyes suddenly widened.

"It smells of salt!" Someone in the crowd suddenly burst into applause, startling Zhao Zheng. Then Zhao Zheng unreasonably saw that everyone looked happy and climaxed.

"Panyu is barren, so there may not be salt for three meals." Wang Dutou said with relief.

"Isn't Panyu by the sea? I have seen many of these salt pans. Zhao Zheng was a little puzzled.

Sun He looked at Zhao Zheng with some doubts, and did he need to ask such an obvious answer: "Salt is a patent of the government, and we don't dare to dry salt privately, so we bring salt to these prisoners." ”

Zhao Zheng was stunned, it seemed that the plan had changed, and he had to take some risks.

Seaweed is a spore reproduction, the most difficult to take seeds and seedlings, and there are requirements for water temperature, sea water salinity, etc., and many of the techniques in it are very troublesome to explain, Zhao Zheng did not fully understand, and some things cannot be completely determined with the current technology, so I also count on God to appreciate the meal.

Zhao Zheng chose a shallow beach where seaweed was grown, but he couldn't come to the site every day to check it, so he needed a helper, a helper who could read.

"Who wants to follow me, to be literate?"

There were many literate prisoners in exile, but only one person raised his hand that day, and the crowd obviously had a strong distrust of Zhao Zheng.

"Boy, you're in luck." Zhao Zheng said to the kid who raised his hand.

"What's your name?"

"You Xiong...... Word restoration. ”

In fact, in less than two years, You Xiong also felt that he raised his hand that day as if it was the will of heaven in the dark, he didn't trust Zhao Zheng originally, what can a child do? But no one raised their hands that day, which made him feel a little pitiful for the child, after all, since he came, he could eat a few full meals and live in a clean house.

So he decided to help him, so he raised his hand.

"You Xiong, 23 years old, from Quanzhou, Fujian, raised people in Jiading in the 17th year, and was sentenced to exile because his wife and others were beaten to death because of their anger." Zhao Zheng looked through the information that Wang Dutou gave him, and read it out softly.

"Dare to ask the little fairy chief, what is this spores?"

"Dare to ask Xiao Xianchang, what is the reason for using silver nitrate to test salinity?"

Within three days, You Xiong was impressed by Zhao Zheng, in his opinion, Zhao Zheng's breadth of knowledge is staggering, astronomy and geography, and the subset of history is all-encompassing.

And he's just a child, isn't there really someone who was born to know?

――

Zaoyang Baiyuan Taoist Temple, Huang Daochang took Zhao Zheng's letter and read it to Da Lang and Erlang, the brothers were sometimes sad and sometimes happy, Zhao Zheng said in the letter that he would not be able to come back at the end of this year. In this way, no one in the Taoist temple dared to secretly take them out to play, although Zhao Zheng was younger than them, he knew a lot of things, and he spoke funny, the most important thing was that he was not afraid of the master, and the master did not punish him much.

The master was a little eccentric, and when he thought of this, the two brothers pouted in their hearts, and they were petty in their hearts, thinking that they would not serve the rice to the master for a while.

Zhao Zheng also said in the letter that he would come back at the beginning of spring next year, and he would bring them a lot of fun toys at that time, and this time he sent it along with the letter, as well as the latest issue of Dragon Ball.

Huang Daochang looked at the two apprentices' happy and sad expressions and felt funny, he put away the latest dragon balls, stipulating how many words they had to know before giving them, and the two brothers heard a howl and ran out.

Da Lang no longer looks like a little master, and Erlang has no gloom in the past, showing a childish temperament, Huang Daochang is very happy, and all this happened after Zhao Zheng came.

For the eccentricity of his apprentices, Huang Daochang is naturally clear, but Zhao Zheng is kind-hearted, although he has great wisdom, he will not compromise the means, so Huang Daochang is also resigned.

Huang Daochang took out Zhao Zheng's letter to himself again, read it again and again, laughed and scolded the stupid child, and then thought about how to reply to Zhao Zheng.

Everything is fine in Baiyun Taoist Temple, a month after Zhao Zheng left, Zaoyang has ushered in the first snow, but the road widening from the foot of the mountain to Baiyun Taoist Temple has not stopped, it is close to completion, Huang Daochang knows that the life of the village at the foot of the mountain is a little difficult, so he has increased his salary again, and from time to time he adds some meat to his daily meals.

The wall of the Taoist temple has also been repaired, and it has been fully circled on the original basis, and it is also being renovated, and the incense money that comes in is not like it, especially the king of Zaoyang, who donated a thousand taels of silver to the merit box at one time last time, which made the zodiac chief very worried, afraid that the king had another plan, and the money could not be returned, and he dared to use it, but fortunately it was sealed.

Recently, there have been more and more gentlemen from Liangshang who have come to the Taoist temple, but fortunately, with Li De, all the thieves were taken down and sent to the official mansion, and Shi Zhijun also sent nearly fifty people to be stationed around the Taoist temple.

However, Shi Zhijun's methods frightened Huang Daochang, and the thieves caught were all dealt with by military law, and the law was corrected on the spot. In the face of all kinds of worries, Huang Daochang also wrote a letter to Zhao Zheng.

The New Year is approaching, how is San Lang doing lately?

――

The snow is falling in Zaoyang, but the sun is shining here in Panyu, and you can only wear a single coat.

Zhao Guangle talked with him in Zhao Zheng's mansion, and after two months of communication, Zhao Guangle naturally knew that the child in front of him was extraordinary, and even Shi Xianggong respected him very much, of course, he had something extraordinary.

Today Zhao Zheng invited him to come to the house as a guest, and he especially wanted to thank him for being busy with his land deed, which is a coal mine in the northeast of Guangzhou City, and it is a terra nullius.

"I wonder what the little fairy chief wants to do in that barren mountain? In the past few days, I have also heard some rumors, and I learned that the little fairy chief has invited a lot of craftsmen, if it is to open up a dojo, I will go to a few good places for the little fairy to choose, and I don't have to go anywhere to a barren place. Zhao Guangle didn't know what kind of wind Zhao Zheng smoked, so he deliberately spent fifty yuan to buy the barren mountain from the government.

Zhao Zheng looked at Zhao Guangle with a puzzled expression, knowing that it was impossible to hide the coal mine, and felt that this matter should be open and honest: "Don't hide it from Zhao Zhixian, that place is a coal mountain, I need to use this material to refine tools." "Coal was already very popular in the Southern Song Dynasty and was used for heating.

Saying that, Zhao Zheng asked You Xiong to send a beautifully packaged small box over: "This thing was obtained by accident when I was refining the weapon, and it was rescued from the county honor." ”

Zhao Zheng opened the small box, and inside was a bead the size of a copper coin. That thing was glass, which he and the two blacksmiths had made, but in view of the limitations of technology, the glass was a little muddy, and the surface was not very smooth, but it was rare and expensive, and it was a real treasure in this era.

Soda ash is needed to make glass, although it can be directly refined with table salt, but the cost is too large, the corrosion of the utensils is also serious, and the soda ash is not pure. Zhao Zheng has always wanted to use the famous Hou's alkali method in later generations, but he has no choice but to use the raw materials of Hou's alkali method to produce salt and combined ammonia. This combined ammonia requires a large amount of coal production. In Zaoyang, Zhao Zheng does not have these conditions, and can only refine on a small scale, and the finished product is only a few beads.

Zhao Guangle saw the beads in the box, his eyes were as big as the beads, but he quickly calmed down, although he had just entered the officialdom, he still had this bit of qi cultivation.

"Such a valuable thing, Zhao is ashamed." In Zhao Guangle's opinion, the beads are smooth and transparent, and they are hundreds of times on the market.

Zhao Zheng couldn't help but want to laugh when he saw Zhao Guangle's expression, and this smile had a meaningful taste in Zhao Guangle's eyes.

"Zhao Xianzun just take it away, send it to friends, and don't shirk it." Having said that, Zhao Guangle could only accept it, and the coal mine was just a trivial matter, and there was no risk.

"Dare to ask the little fairy chief, what is the name of this thing?"

"Uh, glass beads. Calling glass beads is also acceptable. ”

"Zhao Xianzun, please come with me, the official family asked me to be in charge of the Tuntian, this Tuntian now has a land."

Zhao Guangle was a little surprised: "The little fairy is polite, just call me a word." Dare to ask where is this field? Zhao has been here for almost two months, but he hasn't heard of the little fairy ......"

(During the new book, Xiaoqing asked for a few recommendations here, and I hope that all the officials will not be stingy.) ）
