Three Kingdoms, at the beginning of the game, recognize the thief as the father, hit the spectacle,

He is a rough man, although he can read and write, but compared to those specialized literati, Wei Xian must belong to the ranks of the rough man, and he doesn't have so many twists and turns in his heart.

The character of a rough man has always been straightforward. Now that he felt the difficulty of building this large library, he did not say anything big, but honestly expressed his thoughts to Zhang Yan.

Fortunately, Zhang Yan had already expected the difficulty of this thing, so not only did he not feel unhappy, but he felt more relieved about Wei Xian's character.

"Well, it doesn't matter. I also know that this big library is more complicated. You can take your time. As long as the quality is guaranteed, it doesn't matter if it takes more time and manpower."

"This library was built for Lujiang County, so it has the financial support of the entire Lujiang River. It's not like I used to pay for it alone. You don't have to worry too much about costs and the like."

"As for other things, if you can't finish it, you can put it back. The construction of the spectacle is the top priority at present. This is related to our talent pool in Lujiang. If it is done one day earlier, I can also make the entire Lujiang ten The entire city is controlled through this administrative system."

After exhorting Wei Xian, Zhang Yan didn't say too much, he believed that the other party would naturally be able to handle this matter well.

And then, after all these things were arranged, Zhang Yan also felt a slight exhaustion flooding his heart.

"Hmm... I'm afraid it's been an hour?"

Glancing at the sun outside the window, Zhang Yan realized that it was approaching noon, and he also had a feeling that he had returned to the past and was immersed in those historical strategy games.

Just arranging some simple things, as if pressing a few buttons in the game, time passed by Zhang Yan unconsciously.

But fortunately, as long as things are arranged properly, a job like today's may only happen once in ten days and a half months.Most of the time, he can still enjoy his degenerate life as a privileged class.

"Okay...then, only Yuanzhou and Deheng are left?"

Heaving a sigh of relief, under Ma Jun's expectant gaze, Zhang Yan put his gaze on the two of them for the first time.

"As I said before, Zhang Ju, you first use the calculation scriptures I gave you as a basis. I hope you can organize and summarize the existing calculations of the entire Dahan, and initially form a complete system, which is convenient We will continue to pass on this knowledge in the future.”

"Of course, this process will definitely not happen overnight, and it will not take a while to understand all the ten books of the Sutra."

"Before you complete this task, I will provide you with a salary according to the lowest level of county officials, that is, ordinary county magistrates and county lieutenants. At the same time, I will provide you with a quiet environment and good living security. I hope you He was able to concentrate and concentrate on his studies.”

First, arrange Zhang Ju's affairs. Since the other party is different from Ma Jun, he is a standard theoretical scholar. Therefore, rather than restricting the other party through some kind of requirements, Zhang Yan hopes that the other party can do it under a large scale set by himself. develop freely.

As for what kind of state the Shusuan of the Eastern Han Dynasty will develop in the end, to be honest, he doesn't care.

As a ruler, what Zhang Yan can do is only to create a soil for the development of theoretical science.

Opposite him, Zhang Ju was obviously very satisfied with this semi-indulgent attitude, so he bowed to Zhang Yanyi and echoed him aloud.

"Thanks to the lord's great love, Ju must go all out."

As a son of a family with a certain historical origin, although Zhang Ju said that his family has been in decline now, and he is no longer as brilliant as his ancestor Zhang Heng was in the past, but compared with actively becoming an official, by improving his power to go To rejuvenate the Zhang family, he hopes that he can make achievements in knowledge, especially the calculations that his ancestor Zhang Heng was very good at, so as to glorify the family.

Now that Zhang Yan can give him a comfortable environment for him to concentrate on his studies, Zhang Ju naturally has nothing to say in his heart.

On the other side, Zhang Yan also nodded at the moment. The reason why he started to give instructions to Zhang Ju among the two is because in his conception, Zhang Ju will only complete the induction and summary of some theoretical knowledge first. .

After the popularization of mathematics knowledge, Zhang Yan will put these scholars who are proficient in mathematics into various experimental groups, and use mathematics as a weapon to promote the improvement and innovation of some of his creations.

For these things, Zhang Yan naturally didn't need to give too many instructions.

After all, science and knowledge will not deceive people, let alone change according to the personal wishes of those in power.

In a few words, Zhang Ju's affairs were arranged properly, and Zhang Yan smiled slightly, focusing on his last major event of the day.

"Deheng, have you learned all the things I gave you a few days ago?"

Chapter 32 Let's Go Clean the Dung

"Don't worry, my lord. I have studied the classics hard these few days, until I forgot to eat every day and did not distinguish between day and night. Finally, I have gained something."

"Now, although I can't say that I am instructing the method provided by the lord, but in just less than a month, I have made a lot of progress in the previous process of investigating things through this scientific comparison and recording method. results."

"My lord, you can come up with a question. I have been waiting for this day for a long time!"

Excitedly, he said to Zhang Yan that Ma Jun had been looking forward to this moment a long time ago. He had seen Zhang Yan order various things before, but he did not mention his own arrangements. Can't sit on the mat.

Now that Zhang Yan finally started to ask about his progress, he naturally showed a confident look.

For the things that Zhang Yan gave him at the beginning, Ma Jun has indeed put in a lot of effort during this period, even if he didn't forget to eat and sleep as he said, but this effort can be seen by everyone.

It is precisely because of this that although it will take some time for him to be truly proficient in this brand-new experimental method, if he applies it according to the script, Ma Jun has already found some ways.

Sitting not far from Zhang Yan now, Ma Jun seemed a little impatient.

……

"Hehe, have you been waiting for a long time?"

"Indeed, not only you, I have been waiting for this day for a long time."

On the other side, Zhang Yan also said to Ma Jun with a smile.

As a young man born in later generations, in Zhang Yan's mind, there are actually many things that he wants to achieve in this era.

Perhaps due to the historical factors of the repeated invasions of the land of China more than 1000 years later, these things are all more or less related to "firepower" and "shock".

From the simplest artillery, to steam paddle ships, to some more complex land combat machinery...

To be honest, Zhang Yan doesn't know what step he can take himself, and whether he can use his influence to make Huaxia not only achieve "benevolence and grandeur, and obedient people will be helpless in every difficulty" in the next few thousand years, At the same time, it is really like the records in the "Pingwo Zhao" promulgated by Ming Shenzong Zhu Yijun, so that "righteousness and martial arts will be promoted, and those who jump the beam will be killed even if they are strong."

It's just that some things are like this, and it's not that you don't have to do it because you can't do it.

On the other hand, it is precisely because the research and development of artillery and other weapons is full of ups and downs. When Zhang Yan really brought this kind of war king onto the stage of history more than 1000 years ago, he was able to enjoy the convenience brought by that kind of cross-era military force.

At that time, let alone conquer Loulan in the west to rebuild the Protectorate of the Western Regions, even if it is to attack the Xiongnu for three thousand miles in the north, and turn to Fusang in the east, turning the now barren Fusang country into China's "since ancient times", Zhang Yan It also has sufficient confidence.

Of course, food has to be eaten bite by bite, and the road has to be taken step by step. The research and development of weapons has never been something that can be accomplished overnight.

Only now, Zhang Yan finally took the first step in this endless journey.

"As I said at the beginning, Deheng, as long as you pass this test, I will allocate a budget of 600 million or more to the research and development of a new type of long-range weapon."

"As for this weapon, at present I only have the most basic idea, some specific things, and you need to explore bit by bit during the experiment."

"How? If you feel that you have a certain degree of confidence, then I will announce the content of the trial for you."

Smiling, he said to Ma Jun that Zhang Yan had been thinking about the content of this time for a long time before finally deciding on a suitable direction.

Opposite him, Ma Jun nodded vigorously when he heard the words, and his expression became very firm.

"My lord, please come up with a question."

He didn't advertise how confident he was, but just this sentence made Zhang Yan feel the determination of the other party, and at the same time, he felt a sense of relief in his heart.

"Back then... when I was in junior high school, I first came into contact with this thing. Did I learn it for a week or two?"

"Ma Jun was able to quickly understand and accept this new thing in the relatively ignorant Qin, Han, Wei and Jin periods. It didn't even take me any more time than I did at the time. I think it took a lot of thought."

Secretly admired the other party's savvy and diligence in his heart, although Zhang Yan's heart was a little complicated at the moment, he still took a blank piece of paper and started writing on it like this.

After a while, two big characters flying like dragons and phoenixes appeared on the paper.

"Here, let's take a look."

With an uncontrollable smile on Zhang Yan's face at the moment, he just handed the blank paper to Ma Jun beside him.

As for the other party, after looking at the two big characters excitedly, the whole person froze for an instant, and his face also turned gray and pale.

……

"Tao...Tao dung?"

"My lord, this is—"

Looking at the two large characters in astonishment, Ma Jun looked left and right, and after repeatedly confirming that he had read correctly several times, he looked in Zhang Yan's direction with some confusion.

At the same time, Zhang Ju and others, who were more familiar with Ma Jun, also secretly raised their ears, as if they wanted to hear why Zhang Yan made such a treacherous decision.

"My lord, although there is no distinction between high and low in this matter, it is always necessary to find out some principles and laws from the development and changes of things."

"This yellow and white thing is inherently filthy. My lord, you made this decision. Could it be that you want to test my heart?"

"My lord! There is no need for this!"

A flustered look gradually appeared on his face. Ma Jun thought that Zhang Yan would test him on some natural phenomena, or strange skills such as metal and iron, but he didn't want the other party to directly pick up the two characters of dung. Let him take his breath away for a moment.

No matter how cautious he was, he would never have thought that Zhang Yan would put him together with that kind of thing.

"Hehe, what's the matter, look down on the dung-cleaning workers?"

"Deheng, your situation is small. You know, this excrement is of great significance to the people's livelihood."

Smiling and mentioning Ma Jun, Zhang Yan saw that he hadn't reacted yet, so he took the initiative to explain to the other party.

"Deheng, you are also from the Ma family, a big family in Fufeng area. Although you are no longer as rich as you used to be, at least your family still has a hundred acres of fertile land."

"Let me ask you a question, where do you usually use the waste like cattle manure in your house, and how do you deal with it?"

In this way, he guided the other party to think little by little, and soon, Zhang Yan found that the other party's expression gradually became serious, obviously thinking of something.

Chapter 33 Did you forget something?

"My lord, my Ma's family does have a few cattle, and the feces and urine of cattle and sheep are usually piled up by my father on a plain far away from the courtyard, and they are retting together with the soil on the plain. made dung."

"In this way, during the winter of that year, we can pull the manure into the fallow field, and in this way nourish the soil and prevent the soil from becoming barren or even desertified."

"My lord wants to test my content, could it be related to these things?"

Looking at his lord with some uncertainty, Ma Jun no longer repulsed him as before, but after mentioning this matter, he subconsciously used the method Zhang Yan gave him to think about the principle of fertilizing the field with dung.

On the opposite side of him, Zhang Yan nodded in satisfaction when he heard the words, and he no longer kept it up, and just gave orders to Ma Jun.

"It's really a child who can be taught. Although what you said, Deheng, is not entirely correct, it is not far behind."

"The content of this test for you is related to the dung that can be seen everywhere in the farmland."

After signaling to Ma Jun, Zhang Yan already had such an expression at the moment.

From what Ma Jun just said, it can be seen that in the Eastern Han Dynasty 2000 years ago, many powerful landlords in the Guanzhong area had already mastered the relatively primitive method of increasing food production, such as manure composting, rather than relying solely on primitive The slash-and-burn farming, fallow to fertilize the fields.

On the contrary, it is those self-cultivated farmers with little background, or those tenant farmers who work for landlords and powerfuls. Because the nobles and powerfuls have locked up the means of production, that is, knowledge, they have not yet had a suitable channel to understand the production and use of organic fertilizers.

But it doesn't matter too much. Now that there is already a rudimentary form of retting dung, it would not be too difficult to make a similar nitrate soil.

"Deheng, although what I gave you this time is a test, in a sense, it is an indispensable part of the process of inventing the weapon I mentioned."

"As for the content of this test, it is divided into three stages, interlocking with each other, and the difficulty gradually increases."

Zhang Yan took a deep breath, and then slowly described the goal and direction he had set in Ma Jun's scribbling record.
