Xu Qilin didn't hide it, nodded, and said, "Does the king have any suggestions?" ”

Wang Xun smiled bitterly and said, "Xia Guan thinks that if he wants to reduce the cost of Cao Yun, he must open mountains and pave roads, dig stones and rivers, and this financial and manpower consumption is probably very huge." ”

Xu Qilin patted the materials on the table lightly and asked, "Is it all written on this?" ”

Wang Xun shook his head and said, "Xia Guan has not written, if Xu Cheng wants to see it, Xia Guan will be able to submit it tomorrow." ”

"Let's show it to someone tomorrow!" Xu Qilin smiled and said, "Wang is familiar with Cao Zheng, and he has to consult often!" Well, you go down and write the suggestion. ”

"Yes, the next official will retire." Wang Xun finished his salute and turned to leave.

Xu Qilin looked at Wang Xun's back, thought thoughtfully for a while, and then opened the file and read it carefully.

According to the current Cao Zheng, the rent and Yong adjustment imported into Guanzhong are mainly Jianghuai. Because the south of the Yangtze River is a large place and the climate is suitable, the population is similar to that of the Central Plains, and there is no conquest, and the materials are relatively rich.

In February every year, the Cao Yun ship enters Doumen from Yangzhou and starts the Cao Yun journey. In April, the boat crosses the Huai into Bian, often because of the shallow water, and does not reach the mouth of the river until June and July; At this time, the river rises, and it is necessary to wait until the water falls in the first month before going up to the river into Luo......

Cao Yun is very bitter, looking at this timeline, Xu Qilin couldn't help but sigh. For more than half a year, or even a year, it takes to be able to go back and forth, and those boats and sailors are really hard, no wonder the book says that the Cao Yun has increased the burden on the people?

Moreover, the time dragged on for such a long time, and the delay on the road had to eat and drink, which was also quite expensive!

Xu Qilin sighed with emotion, and calculated that the time to stay on the road and wait for the water to rise and fall was longer than the time to sail.

What the hell is this? It's not the highway congestion of the holidays in the future, as for this? Nobody thinks it's a problem, is it?

After thinking for a while, Xu Qilin looked down again and found the problem again. It turned out that Jiangnan boatmen were not familiar with water conditions, and when sailing on rivers such as the Yellow River and the Bianhe River, they often had to hire river division sailors.

Isn't this a duplicate expense? Xu Qilin frowned again.

This material is good, but it is not detailed enough, and if you can list the detailed cost of each section of the boat, you can more intuitively see where it needs to be improved.

Of course, Xu Qilin can now see from this that in order to avoid Sanmenxia Zhushan, the cost of transporting grain from Luoyang to Shaanzhou by land for 300 miles is a big one.

If the ship forcibly passes through the pillar, the probability of ship destruction and death is too high, and the loss is huge.

Xu Qilin found a map, carefully marked several key points on the road, and wrote down the problems he found and his thoughts on the paper.

In fact, even if you don't know what water conditions are, don't know how to sail, and don't go on field investigations, through the information compiled by Wang Xun, as a person with later thinking, like Xu Qilin, you can also see many problems.

First of all, there are many disadvantages of the direct transport method, Jiangnan Cao boat all the way to Luoyang, first in February in Yangzhou to gather, the rainy season is normal, you can set off directly, the rainy season is late, Cao boat sometimes needs to be in Yangzhou for a month or two.

Then crossing the Huai into the Bian, to see the depth of the water, to reach the mouth of the river to see the water rise and fall, into the Yellow River often need to hire another river workers......

In this way, the delay time on the road sometimes reached five or six months, which is equivalent to the time of normal grain transportation to Luoyang.

If the coiling and delayed time can be eliminated, it will save the crew of the boat several months of food and drink, which is a lot of money.

Xu Qilin gradually decomposed the entire Cao Yun process and formed several links, which made the reform of Cao Yun more clear.

Even if it does not involve a revolution in engineering technology, but only improves the procedure to minimize the cost of each link, it also means the success of the Caoyun reform.

Numbers, there must be more specific figures, in order to carry out fine cost accounting, in order to reduce costs to the bones.

Xu Qilin put down the pen and paper, breathed a sigh of relief, and became more confident in reforming Caoyun.

However, even if the calculations are accurate and the data is detailed, they may not be able to win the trust of others.

Thinking that the Cao Yun will start in February next year, Xu Qilin feels the urgency of time and the arduousness of the task.

Although theoretically there is no need to spend a lot of money on construction and digging rocks, in order to achieve segmented transportation, the transshipment warehouse must be built, and it is not one or two simple, and it is not possible to build a small one.

Do you want to invest all the profits of the big profit bank? As soon as Xu Qilin had this thought, he felt that it was inappropriate.

Perhaps, there is a better way, similar to the pre-sale of houses, is it possible to get the money first and then work?

Xu Qilin had a vague idea, but before he could calm down and think about it carefully, someone knocked on the door and entered.

Li Chunfeng seemed to be full of joy and a little excited, holding the freshly printed "Elementary Mathematics" with the scent of ink.

"Xu Cheng-" Li Chunfeng waved the book in his hand to Xu Qilin, and said with a smile, "It's finally printed, and the digital symbol system you mentioned is basically complete!" These days, I have also mastered and familiarized myself with the use of number symbols, and it is very convenient and fast to use them for calculations, and the process is clear at a glance. ”

Xu Qilin was also happy in his heart, it was really easy to cheat this free labor, and he saved himself a lot of energy and time.

"Dr. Li is very grateful for his hard work!" Xu Qilin thanked him and said sincerely, "Dr. Li thinks that this number symbol is easy to use, and he should make more efforts to promote it." ”

"That's nature." Li Chunfeng agreed without thinking about it, and said, "It is an unshirkable responsibility to promote mathematical research and development." ”

Then Xu thanked him first. Well, there is another thing to give to Dr. Lee, which is accurate, fast, and dexterous in calculation. Xu Qilin arched his hand, asked Li Chunfeng to sit down, and poured tea and water for him with his own hands.

Li Chunfeng picked up the teacup and put it down, and asked a little eagerly, "Where is this thing, bring it to me quickly." ”

Xu Qilin smiled, got up and went to open the cabinet next to him, but saw a bunch of abacus inside, all of which were wooden and painted. One of them is made of sandalwood, and the shape is also small and exquisite, which looks very high-grade and distinctive.

Handing the copper abacus and a book of formulas to Li Chunfeng, Xu Qilin explained, "This is an abacus, with formulas, addition, subtraction, multiplication and division can be abacus, after mastering it, it can be called god speed." ”

Li Chunfeng picked up the abacus and fiddled with it a few times, and when he went to the regulation of the fourth, he immediately understood the meaning of the expression, and said, "Well, it's similar to a calculation, what is the function, wait until you go back and try again." ”

As he spoke, he pointed to the cabinet and guessed, "The abacus there is Xu Cheng going to send to the students of the Arithmetic Hall to teach abacus?" ”

Xu Qilin nodded and said, "In a while, there will also be abacus with formulas for sale on the market." But I think it will take a long time to popularize it. ”

"As long as it is convenient to use and the reputation spreads, why worry about no one using it?" Li Chunfeng didn't care too much about this, and put away the mantra book and abacus.

When he was about to get up to say goodbye, he suddenly remembered something again, and said, "Xu Cheng wants to inquire about something, and that Pan Daoxin is the grandson of Pan Shizheng, the master of Maoshan Sect, and Liu Zhenghe is the son of the famous Liu Daohe......"

The Maoshan sect is a Taoist sect formed with Maoshan as the ancestral court. It inherits the Shangqing faction and is another name for the Shangqing faction with Maoshan as the development center. Its actual creator is Tao Hongjing.

And Pan Shizheng should be regarded as the third generation of the grandmaster of the Maoshan Sect, and his teacher is Wang Yuanzhi, who is known as the "King Master".

It is said that Wang Yuanzhi was a miraculous prophet, and he made accurate predictions of various political changes at that time. Including Li Yuan will win the world, Li Er will be the Prince of Peace and so on.

After Li Er ascended the throne, he built a Taiping Temple for Wang Yuanzhi in Maoshan Mountain. When Gaozong and Wu Zetian were in the past, they both added honorary titles to him.

And Pan Shizheng was ordered by his teacher to come to Zhongyue Songshan Temple, to vigorously develop the Maoshan Sect in the north, open up the position of the Maoshan Sect, and resolutely compete with Buddhism.

But when Pan Shizheng was really famous in the world, he had to wait until Li Zhi succeeded to the throne and was awarded the title of "Heavenly Master".

"Liu Aidao, his son Liu Zhenghe, and Pan Daoxin, came to Chang'an to observe the 'Three Teachings and Balances'." Li Chunfeng finally explained, looked at Xu Qilin and said, "His Royal Highness the Crown Prince will gather all the officials and ministers in the near future, and the three scholars will discuss the Tao in the Hongwen Palace, Xu Cheng also knows about this important matter, right?" ”

I know a fart. Xu Qilin smiled, obviously knowing very little about what the argument was, and he was not very interested.

Li Chunfeng looked at Xu Qilin's appearance and knew that he didn't know anything about it, so he couldn't help but smile and said, "It's a matter of tongue, and I don't care much about it." ”

The controversy between the three religions of Confucianism, Buddhism and Taoism is mainly the dispute between Buddhism and Taoism, since Cao Zhi wrote "Arguments on Taoism" in the Three Kingdoms era, refuting the Taoist theory of immortality and immortality, etc., and unveiling the beginning of the balance of the three religions.

The dispute between Taoism and Buddhism has gone through the Southern Dynasties, Xiao Qi, Northern Dynasties, Sui and Tang Dynasties, Song Dynasties, Southern Song Dynasty, Ming Dynasty, Qing Dynasty, and Republic of China, which can be said to have a long history.

Since the seventh year of Tang Gaozu Wude, every major festival or emperor's birthday, the imperial court will hold the "Three Teachings Discussion and Balance", and the three schools of Taoism, Confucianism and Buddhism must send representatives to debate the scriptures and meanings of their own families with others.

To put it bluntly, the doctrinal and liturgical arguments of the three are usually in conflict over the faith of the emperor and the larger number of believers.

Therefore, the so-called "discussion of the Tao" is nothing more than a power struggle between groups and organizations, and if you win, you will have vested interests, and if you lose, you will hand over power. However, compared with the thousand-year-old dispute between Christianity and Christianity, the dispute between Confucianism, Buddhism and Taoism is relatively mild.

Although Xu Qilin was not interested in this, he just asked casually, "In Dr. Li's opinion, who is the leader of the three religions?" ”

Li Chunfeng pondered for a moment and said, "Taoist Cai Huang, preaching is good, and he is the only one who is beautiful; Master Huijing of Jiguo Temple has exquisite Buddhism and is also involved in Taoism. It's hard to speculate. ”

Not only must you be familiar with your own scriptures, but you must also be familiar with the teachings of other schools, so that you can attack their weaknesses and make it difficult to make mistakes.

Hehe, it's none of my business! It's just that Li Chengqian seems to be quite normal now, at least on the surface, he has not been completely exposed and has become notorious. Otherwise, His Majesty Li Er would not have let him preside over the three sects.

Li Chunfeng took the abacus and left, and Xu Qilin also left the three teachings behind. There are still a lot of things on his side, who cares if he is a monk and a Taoist priest?

……………

Jiucheng Palace.

The two sisters, Jinyang and Xincheng, were whispering, but it was about the title of Xiao Zhao after he came.

Xincheng didn't expect that the son-in-law was a little older, but he was more thoughtful.

"Oh, in front of Sister Xiao Zhao, you can't call Uncle Xiao, you can only call Xu Xiaolang." Xincheng listened to his sister's explanation, and pulled the hair hanging down his ears in some confusion.

The son nodded vigorously and patiently explained, "Do you think, Xu Xiaolang and Xiao Zhao are brother and sister, if Xu Xiaolang is called uncle, then Xiao Zhao will have to change his name?" ”

"What do you call it?" Xincheng obviously still can't figure out how to arrange this generation, and looks at Sister A stupidly.

The son shook his head and said, "Then you have to call her sister-in-law, why don't you understand?" ”

Xincheng blinked her eyes wide, thinking that it was nothing to call her sister-in-law, didn't she and Sister Ah also have several sisters-in-law who were not very old?

Their sister-in-law is naturally Li Yuan's daughter, not only daughters, but also sons, Li Yuan left Li Er with more than 30 brothers and sisters!

is to abdicate and become the queen of the throne, Li Yuan is not idle, he is always concentrating on cultivating in the harem and working hard to create villains.

It is estimated that the old man also wants to block His Majesty Li Er, didn't you kill my two sons and several grandchildren, I'll make a bunch of them, see what you do?

When Li Er ascended the throne as emperor, some of his younger brothers and sisters were still young, and he suddenly became the eldest brother. The ancients said: "The eldest brother is like a father", for the sake of face, he also pretended to be a brother and a brother, brother and sister are affectionate.

Xincheng thought about his sister-in-law and uncle, who were about the same age as him, and felt that it was not a big deal to call Xiaozhao sister-in-law.

The son rolled his eyes, didn't bother to analyze and explain, and ordered very strongly, "Don't scream, don't scream, when you mention it, it's Xu Xiaolang, do you remember?" ”

Oh, Xincheng saw that Sister Ah seemed to be a little angry, so she hurriedly responded, and her little head nodded happily, "Xu Xiaolang, Xu Xiaolang, I remember." ”

The son was a little relieved, and his tone softened, and he said, "There is also the godsister Ah Ke brought by Xiao Zhao, although she is a folk girl and a blind person, she is also our guest, so you must treat others well." ”

"Can't you see?" Xincheng thought about it, frowned slightly and said, "That's really pitiful, it's not good to eat food." ”

Just know how to eat! The son resisted the urge to roll his eyes and said, "Yes, so let's treat her well." ”

Xincheng nodded his little head, grinned and said, "Xu Xiaolang, Sister Xiaozhao, Sister Ake, that's right, right?" ”

The son nodded, thinking that this girl couldn't remember if she talked too much, maybe it would make a mess even more!

"Let's go, let's go to the palace gate and wait for Xiao Zhao together." The son got up and said, "Uncle must have asked her to bring a lot of good things, I'm really anxious to see it!" ”
