Di Renjie said with a smile: "Cen Zhongcheng's steps are quite fast. ”

Li Zhi sat down again and looked at the Qujiang River under construction in the distance, "It is true that this Qujiang Pond is being built too slowly. ”

Not long after Cen Wenwen left, Zhang Cambodia came, he walked in front of him, picked up the wine bowl and took a big sip, "Your Majesty asked Ma Zhou to go to Longyou to check the acres of land." ”

Di Renjie snorted coldly: "Most of the hands of those people in Longyoumen are dirty. ”

Zhang Cambodia sighed, "It seems that many people's heads are about to fall to the ground." ”

Li Zhi drank the wine casually and sighed in discouragement.

In Lishan, there were Taoist priests from afar, they came from all over the Central Plains, and these Taoist priests handed over the scrolls in their hands to Yuan Tiangang.

This is the climate change in various parts of the Central Plains from the end of last year to the beginning of spring.

Yuan Tiangang asked: "Can the county marquis really see this year's warmth and coldness from these books?" ”

Zhang Yang looked at the records on the scroll, the one in front of him was the change in the climate of Lingnan, and after reading one volume, he picked up another volume, "Last year, it was warm in the south, but in winter, it was sometimes warm and sometimes cold. ”

"My method is different from Yuan Daochang's speculation method of looking at the sun, moon and stars, I believe in what I can see."

Yuan Tiangang stroked his beard and said: "These things are just a gesture, Lao Dao is very willing to let the people in the Daomen do things for Lishan, when you give the Daomen benefits, we can also feel at ease." ”

Zhang Yang changed his sitting posture, raised his eyes and saw that it was Cen Wenwen riding a horse, and turned over and dismounted in front of him.

When he saw him standing aside, he did not speak.

Zhang Yang continued: "There are not many typhoons blowing towards Lingnan this year, but each one is a strong wind, and even swept the entire Jiangnan East Province, with five strong winds. ”

Yuan Tiangang asked, "What does this mean?" ”

"The climate of the Tang Dynasty is warm, and in the years I have been in Taifu Siqing, I have found that not only the Central Plains, but also the places outside the Guan, including Liaodong and the Tianshan Mountains, have an abnormally warm and cold climate."

"In the southwest, there were two dry summers last year, and the autumn was warmer."

"Typhoons can tell the story of the ocean, because there are many strong winds and they stay inland for a long time, which means that the sea is warm and has enough strength to accumulate typhoons, and last year's autumn was unusually warm, but in winter it was a big cold."

Yuan Tiangang couldn't understand these words anymore, and he asked, "So it's going to be warm this year?" ”

Zhang Yang shook his head and said: "The climate of the world is a whole, every time there is an abnormality, you can see the clues, climate changes should be viewed from multiple angles, I think this year will be a trend of cold and warming." ”

"To prepare for the flooding in Hebei and Jiangnan this summer, Guanzhong should pay attention to the cold wave in the north this year."

Yuan Tiangang bowed his head and said, "Can you know what the weather will be like in the next few days?" ”

"I can't."

"Can't?"

"To predict the climate situation in the next few days, we need to make larger, more detailed observations, which is not possible at the moment," Zhang explained. ”

"I can only prevent possible disasters through the changes in the climate in various parts of the Central Plains, and the agriculture of the Central Plains is weak, no! It should be said that agriculture in the Central Plains is very weak at present. ”

Yuan Tiangang sighed: "In Lao Dao's opinion, you just want to collect these changes, as for whether it is useful or not, you have to look at the after-effects, it will always be useful." ”

"If future generations can find the reasons for the changes from these clues in the future, it is also worthwhile, and the old way will let people continue to observe climate change in various places."

Zhang Yang put these files into the bamboo basket and looked at Cen Wenwen on the side, "What's the matter with Brother Wenwen?" ”

Cen Wenwen said with a straight face: "The letter written by the county marquis, doesn't the county marquis himself know?" ”

"Huh." Zhang Yang patted his head and suddenly came to his senses, "Alas, I almost forgot, there have been too many things recently." ”

Knowing that the two had something important to discuss, Yuan Tiangang felt bored and left.

"Your Majesty said that the county marquis should not make an offer."

"Then Your Majesty thinks the price is appropriate?"

Cen Wenwen was a little impatient when asked like this, "County Marquis, there are many ways to trade between the DPRK and Lishan, and you don't have to talk about money. ”

Zhang Yang beckoned: "Xiaohui! Xiao Wu! ”

The two girls walked briskly, "What does the master command?" ”

The land of Guanzhong has just come out of the cold winter, the sun is warm and pleasant, and I don't want to move after a long time.

Zhang Yang lay on the bamboo chair and said lightly: "Chaozhong and Lishan want to trade paper mills, but Your Majesty is unwilling to come up with 100,000 yuan, let Brother Wen talk, and the two of you will talk to him." ”

"Okay."

Glancing at Xiao Wu and Xiao Hui, Cen Wenwen wanted to speak and stopped, "This ......"

"They are now the backbone of Lishan's production, and even I have to listen to their arrangements for some things, according to the structure of our Lishan, they are the executive CEOs of Lishan."

"What?"

Seeing Zhang Yang's lazy appearance, the two sixteen or seventeen-year-old girls in front of him were able to decide so many major events in Lishan?

Cen Wenwen hesitated for a moment, but still talked to the two girls about the reason.

Xiaohui replied: "According to what Cen Zhongcheng said, there is really no need to talk about money in the transaction between the DPRK and Lishan, and this sentence is actually true. ”

Cen Wenwen stroked his beard and nodded, saying in his heart that they were much more enlightened than Zhang Yang.

Xiao Wu said again: "But Lishan can't lose money, and the DPRK needs to come up with an equal price." ”

"Well, I don't know what the conditions are in Lishan?"

Xiao Hui pondered for a moment and said in a low voice: "I want to give Lishan a privilege to the court." ”

"But it doesn't hurt to say it."

Xiao Hui and Xiao Wu glanced at each other, "There are a lot of goods in Lishan that need to be transported from the southwest and Jiangnan, but the passes in all parts of the Central Plains have to be checked, which has caused a lot of trouble to Lishan. ”

Xiao Wu also added: "Lishan plans to build a seaport near Jiangnan and Dengzhou, and hopes that the DPRK and China will give Lishan permission so that Lishan can transport goods by sea." ”

"By sea? Lishan is going to sea? Where to go? ”

Xiaohui hugged the account book and said: "It's just to transport goods, and when Nanzhao opens up the passes of Jiaozhi, the goods of Nanzhao can also be transported to the Central Plains by sea, so that there is no need to take the Southwest Shu Road." ”

Cen Wenwen glanced at Zhang Yang, and then at the two girls in front of him, their eyes were very good, and they saw the impact of the sea route on the situation in the southwest at a glance, and he couldn't help asking: "Can Nanzhao really open up all parts of Jiaozhi?" ”

Xiao Wu smiled: "This doesn't have to worry about Cen Zhongcheng. ”

"Since Lisan wants to open up a sea route, if you can go to the southwest, you will definitely be able to go to Wajima and Silla."

"Can Cen Zhongcheng give convenience?"

Cen Wenwen then talks to the two girls about the trade of papermaking and sea privileges.

Zhang Yang put the hat over his face, shielded him from the sun, and listened to the negotiation.

The negotiations went smoothly, and Xiao Wu and Xiao Hui made no concessions on the interests of Lishan.

When Cen Wenwen walked over, Zhang Yang looked sideways, and this person's face was not very good, "Brother Wenwen has talked about it?" ”

Cen Wenwen waved his hands and said: "Let's go to Chaozhong, Lishan and other Zhongshu provinces for approval." ”

"Thank you very much."

You don't have to pay a penny to buy Lishan's papermaking skills, you just need to give Lishan some privileges.

Things went far smoother than expected, and Cen Wenwen turned over and left in a hurry.

Zhang Yang glanced at it again, "This person is really in a hurry to come and go." ”

Xiaohui stepped forward and said with a happy smile: "Our family business in Lishan is getting bigger and bigger, and now we have to open up a sea route." ”

Xiao Wu said again: "Well, the family business will get bigger and bigger." ”

The next day, His Majesty gave Lishan a very happy approval, not only allowing Lishan to open up a sea route, but also allowing Lishan to call on soldiers and horses from all over the country to escort Lishan when necessary, so as to escort Lishan's transportation.

Business is inseparable from transportation, and the problem of transportation has always been haunting Zhang Yang and Li Yue's hearts.

Transportation is a big problem, the land topography of the Central Plains is complex, the mountains and rivers in the north and south are undulating, and not all places are like the Qinchuan Plain with 800 miles of Guanzhong.

The couple discussed for a long time, and under Zhang Yang's persuasion, Li Yue dismissed the need to build a railway through Nanzhao and Guanzhong.

Because it is necessary to cross the Shu land and pass through the 100,000 mountains in the southwest, this is an impossible task.

Li Yue said in a low voice: "So you still have to borrow the sea route." ”

Zhang Yang's eyes also looked at the map, and nodded: "We have a steam engine, which can be placed on a sea ship in the future, which is a big help for us to take advantage of the sea transportation, of course, we must also take into account safety, and the sea ship must be equipped with firearms." ”

"Will the DPRK and China allow it?"

"This is Nanzhao's firearms, and it has nothing to do with the DPRK and China."

"That's right, the husband is the king of Nanzhao, what Nanzhao's ship looks like, that's Nanzhao's business."

Li Yue said this, still worried in his heart.

The husband's approach is very bold, if the court and the central government know about it, there will inevitably be conflicts, this is all a matter of the future, and arrangements can be made as soon as possible.

These days, Zhang Yang always locks himself in the workshop.

Xiao Qingqing watched as his father put a rough piece of iron on the fixture, fixed it on the lathe, and then used a piece of copper to put it on another fixture.

Daddy stepped on the pedal, and the lathe began to work, and the copper of the cylinder began to turn, and the copper touched the iron sheet, and some of the copper wire was scraped off.

Daddy immediately stopped the lathe, applied some tung oil to the copper, and continued to cut.

And so it goes.

After a long time, after taking off the blade, Zhang Yang sighed: "The power is not enough, and the speed is not enough." ”

"Did Daddy fail again?"

Zhang Yang nodded and said, "Hmm." ”

"What is Daddy doing?"

"Make screws." Zhang Yang took off his leather gloves and said helplessly: "The development of industrial technology is really inseparable from power. ”

Xiao Qingqing laughed and said: "My mother always said that my father pursued too much, and there were too many things he wanted to do well. ”

"Well, I'll think about it again."

If the lathe can't make screws, it doesn't need to exist.

Zhang Yang sat down and drank tea, his eyes fixed on the lathe.

Xiao Qingqing moved a small bench and sat next to his father, supporting his chin with both hands, looking at the lathe.

Thinking about how to upgrade the lathe can give it more power.

Looking at her daughter thoughtfully, she was curious: "What are you thinking?" ”

Xiao Qingqing's eyes moved from the lathe to the wall, "My daughter has read the scroll sent by Uncle Wen, the city wall of Chang'an City is very thick and solid, and my daughter is thinking about how to blow up the wall that is more than ten feet thick." ”

Zhang Yang drank the tea and frowned.

Xiao Qingqing said again: "My daughter heard Aunt Lizhi say that mechanically speaking, you need to find the focus point of the city wall, but the masonry of the city wall of Chang'an City is buried in the ground, and you can't find the focus point at all, even if you use artillery, you need to blow it up many times." ”

At the beginning, this girl and Li Yuan fired a cannon at Chang'an City, but it was just a few bricks and stones on the city wall.

Where is Chang'an City so easy to bomb.

Xiao Qingqing looked sideways and asked, "Daddy, is there any way?" ”

Zhang Yang said in a deep voice: "The method must be in the future, and it is not too difficult." ”

"Daddy, say it quickly."

"It's just that this method is taught to you, and your mother is going to lose her temper again."

"My daughter doesn't tell my mother."

The mother always strictly manages the children, and the father has to comfort the children.

Zhang Yang spread out a piece of paper and began to draw.

Xiao Qingqing simply climbed onto the table and watched his father draw a wall.

"The city wall is made of bricks and stones, but the masonry of the city is very large, but the masonry and masonry support each other, and if the masonry below is not strong, the top will naturally collapse."

Xiao Qingqing listened carefully.

Zhang Yang drew a few circles between the cracks of the masonry and stone, and said in a low voice: "Look at these cracks, if you bury gunpowder in these cracks, in order to improve fault tolerance, you can bury more gunpowder in these cracks, or even cover the entire wall." ”

"My daughter understands, you can first make holes in these cracks, stuff gunpowder in the wall, and detonate them together, and the walls of Chang'an City will definitely collapse."

Zhang Yang found that his daughter was very talented in blasting, and she could understand it at all.

Xiao Qingqing's expression was full of longing, and he said: "Daddy also wants his daughter to blow up Chang'an City?" ”

"Chang'an City will become more and more crowded, gathering so many people, and these populations cannot become productive forces, they will only increase the burden on Guanzhong, and only by tearing down this wall can these populations be released."

Xiao Qingqing smiled and said, "My daughter understands." ”

Zhang Yang drank tea and advised: "I have lost all the gunpowder at home, and I can only play around Chinese New Year's Eve every year." ”

"Daddy, don't worry, my daughter will study and read well."

"Well, when you learn well, you can better bomb Chang'an City."

There were many steps to be taken in the deal between the DPRK and Lishan, and Li Tai personally arranged for the equipment of the original paper mill to be removed, and also handed over the secret recipe of the pulp to Yan Liben's brother Yan Lide.

The original paper mill was vacant and could make more arrangements, and Li Tai planned to move all the lathes in, and the iron foundry and workshop should be separated.

As for how the DPRK wants to use papermaking and how much paper it wants to make, it has nothing to do with Lishan.

Zhang Yang saw the account book brought by Cen Wenwen, the emperor has money in his hands, and he has always been lavish in spending money, and a Tian Khan who is not good at management is not a business opportunity for Lishan.

"Brother Wen, the DPRK and China spent 30,000 guan last year, where did the 30,000 guan go?"

Cen Wenwen was surprised: "Are there so many?" ”

Zhang Yang handed him the account book, "Look at it, Your Majesty spent five thousand yuan just to buy ordnance for the Twelve Guard Mansions, how did you spend this money?" ”

Cen Wenwen was entangled: "Yes, how is this money spent?" ”
