I am the empress, you still tell me to run away?

Li Zhongnong nodded quickly and wrote down all these things. He asked again: "Uncle Le Xian, you said that these fairy grains consume a lot of land, and need to be rotated and interplanted to increase the fertility of the land. Is it only soybeans? I don't know what else?" Are there any other crops?"

Lin Xuan smiled: "This is mine. There are indeed other crops. For example, safflower and alfalfa can be planted in the field to increase the fertility of the land. They can also be used as vegetables or as horses. food."

In the following time, Lin Xuan briefly explained these one by one.

As for the specifics, Dr. Li Zhongnong and others have to practice on their own.

After all, because of different climates, different water and soil, the growth and planting of many crops still need to be adjusted.

The question was pretty much the same, Lin Xuan felt a little thirsty, and was going to pick some melons to quench his thirst.

But thinking of the mechanized tools for planting in modern times, Lin Xuan said again: "Dr. Li, in the final analysis, this way of increasing the land's food products requires more tools besides seed selection!"

Li Zhongnong was stunned, staring at the rake in Lin Xuan's hand: "The one in Le Xianbo's hand is such a tool?"

Lin Xuan was taken aback, and asked back, "This is a nail rake, don't you have one?"

Chapter 68 Hiss, how big is this big fish?! 5K

Seeing Li Zhongnong, a doctor of agriculture, seriously studying the appearance of rakes and hoes, Lin Xuan realized that things were not simple.

Recalling that most of the blacksmiths sold in Tiandu West City were bronze swords and various bronze utensils, Lin Xuan quickly realized that iron utensils in this world had not yet been officially promoted.

It's just that the Dagan copper technology is so advanced that Lin Xuan didn't notice it.

After all, in the game, there are various blueprints produced, so that players can promote the development of technology in the entire world.

Now that there are no players, all technology trees need to gradually develop according to the normal historical trajectory.

To put it simply, in today's Daqian, there is ironmaking technology, but it is not advanced, resulting in very little iron production, and naturally there is no way to promote ironware.

Lin Xuan thought for a while and said, "These are all iron objects. Iron refining is more convenient than bronze refining. The rake I have in my hand is made of iron, which is more convenient than bronze."

"Actually, the rake and hoe are very small tools..."

Before he finished speaking, he saw the excited Dr. Nong holding the rake and looking at it for a while, and then picked up the hoe and looked at it for a while. Soon he found the shovel, sickle and other things that the farmers needed. basic tools.

"Le Xianbo, these, are these iron objects?"

Li Zhongnong asked excitedly.

"Yes, it's all iron."

"Hoes, weeds, and fields."

"Shovel, specially used for digging ditches, for digging soil."

"Sickles are available for harvesting. They are especially useful for rice and weeds."

Lin Xuan introduced one by one that these were all sent by the system when he checked in, and they were purely for him to farm.

To be honest, I really don’t know whose system would be so boring, so giving him these tools, is it a game of survival in the wild?

However, considering that the system has been rare and generous recently, and it is still somewhat useful, I won't talk about it all.

Li Zhongnong quickly asked: "Is it easier to smelt iron than bronze?"

Lin Xuan said: "Well, it's easy to master the technology."

Li Zhongnong asked again: "Is the cost of this ironware high?"

Lin Xuan said: "It's not high, because it is easier to collect iron ore and has more branches. In fact, the current Leisi is made of iron, and it can be improved and made into a plow, which can speed up the repair of the land."

By the way, today's sign-in reward seems to be a blueprint with the words "Quyuanli" written on it.

Quyuanli was an improvement on the previous plow in the Sui and Tang dynasties. In addition to the handrail of the plowshare, it also added plow walls, plow arrows, and plow ratings.

The Quyuan plow is composed of eleven parts made of wood and metal, which can control and adjust the depth of plowing. It is 2.3 feet long and is so huge that it takes two oxen to pull it.

Compared with the Quyuan plow in the Tang Dynasty and the Zhiyuan plow in the Western Han Dynasty, the added plow rating can meet the different needs of deep plowing and shallow plowing.

The improved mold wall has a round shape, which can push the raised soil aside to reduce the resistance of advancement, and can turn over the soil block to cut off the growth of weeds.

There are many advantages.

Just considering that there are relatively few cattle in Dagan, some straight-shaft plows that can be pulled and pulled by one cow are still needed.

In addition, some tread plows are probably needed, and the ground can be plowed only by trampling with human feet.

After all, in this era, the landlords are basically the ones who can raise cattle.

However, in the final analysis, Lin Xuan knew that Dagan's iron-making technology was so poor that it was very difficult to promote Quyuanli in a short period of time, let alone Zhiyuanli and stepping plow.

As for the Dr. Li Zhongnong beside him, his eyes were already red.

"Le Xianbo, you know how to forge copper...Is it iron?"

This question was asked, if it was changed to before crossing, Lin Xuan was afraid that someone would knock on the door with a gun to read the water meter, and take him away by the way.

"will not."

Lin Xuan shook his head.

Iron-making technology, he has it here, and it is also sent by the system to sign in.

However, no matter how much this agricultural doctor Li Zhongnong loves agriculture, Lin Xuan still intends to say less about some key things.

First, it is a good thing to spread knowledge and make friends with other people, but he is not a boy who spreads money. When others ask him, he directly gives the technology to him.

Especially things like iron-making technology, if it gets to the ears of some aristocratic families, the killer will probably step over the threshold again.

After all, in terms of the benefits brought about by the development of the technology of the times, no one can compare with them.

At that time, as long as you have the ironmaking technology and occupy a few more mines, you will have a steady stream of silver and wealth.

Who would not be greedy for such a huge benefit?

Therefore, some of the ironware displayed here by Lin Xuan can be said to be the property left over from the previous dynasty, and there are some excuses.

If you know how to smelt iron and copper, the killers will definitely come and threaten to hand over the technology.

Besides, what if I talk to this Dr. Li Zhongnong and kill him?

After all, Li Zhongnong's real identity was Taifu Temple's Grand Sinong Zhongli, and he quickly understood how impolite his question was, and more importantly, they were not familiar enough to say everything.

This kind of matter still needs to be discussed with His Majesty.

Ironware!

Benefit the country and the people!

Thinking of this, Li Zhongnong's heart became hot again.

You must know that they use wood, stone, and a small amount of bronze to farm, which is not only time-consuming and labor-intensive, but also yields very little, and the people often cannot fill their stomachs, which is quite miserable.

As long as ironware can be promoted, there will be more possibilities in the future of Daqian!

"Le Xianbo, I have been taught today, please accept the next obeisance!"

Having figured it out, Li Zhongnong bowed his head to express his gratitude to Lin Xuan.

Lin Xuan quickly supported the other party, smiled and said: "No need to do this, come on, sit down and rest for a while, and taste this melon."

……

Taifu Temple chief minister Nong Zhongli, also Dr. Li Zhongnong, rushed to the palace as soon as he bid farewell, and reported to Empress Ji Handan about the iron farm tools in Lin Xuan's house.

Empress Ji Handan nodded, indicating that she understood.

"Smelting iron?!"

Unlike Da Si Nong Zhongli, who saw agricultural uses, Empress Ji Handan saw all kinds of weapons made of iron.

"I didn't expect that the last time I went to Lin Xuan's backyard vegetable field, I saw it suddenly."

Empress Ji Han smiled, and went to Lin Xuan's small courtyard after finishing the work here.

After all, according to the advice provided by the queen mother, some things should not be done too obviously, and they need to be relaxed, so as not to exhaust the resources.

In addition, so far, Lin Xuan has brought too many changes. The court needs time to digest, and the aristocratic family also needs time to digest.

If too many changes are brought about at one time, it will easily make the aristocratic families feel scared.

In this way, they will definitely do everything to kill Lin Xuan.

Even if the changes brought about by Lin Xuan seem to bring them unimaginable benefits.

Because at this time, the fear of the unknown will completely blind these people's minds, and they will no longer care about their interests.

Faced with such a situation, Empress Ji Handan was not sure whether she could protect Lin Xuan with confidence.

However, considering that this is related to the cultivation of fairy food, I will ask Lin Xuan in a few days.

……

The next day, Da Si Nong Zhongli approached Geng Yuandao, Shangshu of the Ministry of Industry.

"Master Geng, may I ask if you know how to make iron?"

"Smelting iron?"

Geng Yuandao was questioned.

He found a bamboo slip from the bookshelf next to it, opened it and said: "At present, most of the iron produced by the Ministry of Industry is sponge iron, which needs to be repeatedly forged into iron blocks before it can be smelted and used. Bronze is good."

Zhong Li asked again: "Sir, is there no way to quickly toughen cast iron?"

This matter is very important to him.

What Lin Xuan said yesterday was absolutely not without evidence.

Considering Lin Xuan's attainments in medicine and agriculture, it may not be impossible to have more attainments in other fields.

Therefore, it is absolutely feasible for Lin Xuan to mention the convenience of iron smelting compared to copper casting.

But for professional matters, you have to ask professional people.

Therefore, Zhongli did not go back to Taifu Temple after his downfall, but came directly to the Ministry of Industry and asked Geng Yuandao, Minister of the Ministry of Industry, who would have thought that Geng Yuandao would say that copper making is better than iron smelting!

This is completely different from what Lin Xuan said.

Seeing Zhongli's puzzled expression, Geng Yuandao smiled: "Master Zhong, this way please!"

Zhong Li followed quickly, and the two came to the sample warehouse of the Ministry of Industry. This is a convenient warehouse for finding information and observing the use of samples.

Geng Yuandao pointed to the shelf in front and said, "This is the iron made by the Ministry of Industry, Mr. Zhong, take a look."

Although I don't know why Zhongli came to ask about iron making.

However, considering that Zhongli's entire Taifu Temple is in charge of matters related to immortal food, there is a high probability that he wants to find the farm equipment requested by the Ministry of Industry.

Bronze farm tools were sent to Taifu Temple last time, so maybe they are not enough, and now you want to use iron?

Zhong Li picked up the iron block on the shelf, looked at it carefully for a while, and shook his head.

Compared with the hoes, rakes, shovels, and sickles used by Lin Xuan, these iron blocks are too far behind, and they can only be used to make agricultural tools, which still consumes a lot of energy.

"Master Geng, is there no better iron?"

Zhong Li put back the iron block, somewhat disappointed.

"No, it's just these irons. The effort to refine them is no less than that of copper. This is already the best iron I have refined so far!"

Geng Yuandao said.

Recently, there have been reports of iron ore in various places in Dagan, all of which were discovered during the exploration of copper mines.

There are also many people who have tried refining, but the iron on the shelf in front of them is the best iron, and it is somewhat wasteful to use such iron to make utensils.

Considering that there are so many iron mines, the Ministry of Industry has been worrying about making effective use of these mines.

I just didn't expect Zhongli to come over and ask.

After thinking about it, he felt that something was wrong, and asked directly: "Master Zhong, have you ever seen better iron?"

Geng Yuandao didn't care about self-slapping.

If there is a better iron, he is willing to be beaten in the face.

Zhong Li nodded: "Indeed."

Geng Yuandao's eyes lit up, and he grabbed Zhongli's hand: "Go, take me to have a look!"

Zhong Li was stunned, and Geng Yuandao almost stretched the hand holding the hoe all the year round: "Geng Daren, wait a minute! It's fine to see you, but you need to consult His Majesty's opinion on this matter?"

Geng Yuandao was a little puzzled: "Could it be that this iron has something to do with His Majesty?"
