In April of the second year of Jian'an, the crops in some fields in the south had begun to mature slowly.

This year is another good year, seeing that the branches of the crops are full of heavy fruits, and the whole Guanzhong is covered with a layer of festive colors.

Wen Zhao led some of his subordinates, as well as teachers and students who specialized in agriculture from the Miscellaneous Branch, to inspect the harvest in the fields.

Squatting down, Wen Zhao gently stroked the golden corn with his hand, and finally a happy smile appeared on his face.

He turned his head and said to the people behind him, "This year's grain harvest will be abundant, and no one will go hungry again." ”

Everyone was also overjoyed, and they flattered Chen Xu one after another, and Chen Xu was also a little happy when he heard those words of praise. It's not that he likes other flattery, but that he's really proud of what he does.

If there is no Chen Xu, I am afraid that many homeless people will not be able to obtain land, let alone be able to live in stability in this troubled world.

Although Chen Xu has not been in charge of Guanzhong for a few years, he has implemented a series of policies that benefit the country and the people, so that the people of Guanzhong can live and work in peace and contentment, and the people under his rule praise him.

The spring sun shone on his body, Wen Zhao felt warm, and the spring breeze was blowing, like a lover's gentle touch.

On the banks of the small river, the willow branches hanging in the air are also swaying in the wind. The emerald green of the branches has brought a different kind of vitality to this spring.

The wildflowers on both sides of the road, although still a little green, have also begun to compete for beauty, bees buzz through the flowers, and butterflies do not skimp on their own dancing, dancing in the air against the wind.

Wen Zhao looked at everything in front of him, closed his eyes and opened his arms, embracing the whole spring.

"How nice it would be if this world could be so peaceful forever!"

After reveling in his intoxication for a long time, he came back to his senses, looked at the people behind him with an apologetic face, and said to several old people: "On the eve of this year's harvest, I will issue an edict to let all farmers in the territory select high-yielding and full seeds in the fields. ”

"Once you have collected enough seeds, you can use them to sow them and choose the best of the best. I believe that after several generations of optimization, grain production will certainly increase. ”

Chen Xu does not understand biological science, nor does he know how to improve grain production, so he can only optimize grain varieties through this stupid method.

The genes of the seeds are basically the same, but there will be some differences between their individuals, some advantages and some disadvantages.

Chen Xu just wants to remove those inferior seeds. Then let the high-quality seeds continue to be selected and optimized to get better quality seeds.

"After grain is planted, it needs to be pollinated to grow and bear fruit. If these high-quality seeds are mixed with other fertile fields, it will inevitably affect the quality of the fruits produced by these seeds. ”

"Yes, my experimental base will be specially opened up in a location far away from other farmland, so as to avoid the degradation of these excellent seeds."

One of the old farmers asked, "Pollination, what is pollination?" ”

Wen Zhao was stunned for a moment, and then said with some hesitation: "Well, that is, the combination of male plants and female plants can bear fruit." The process by which they combine is pollination. ”

Chen Xu didn't know much about this knowledge himself, so he took it for granted and began to fool everyone. Anyway, no one else in this era knows about this except him.

When everyone heard this, they all had suspicious looks on their faces.

There is no doubt that both humans and animals can give birth to offspring through mating. However, this is the first time that plants should be like this, and everyone has heard of it.

One of them asked, "So how are the crops pollinated?" ”

Wen Zhao didn't know much about this, but when he asked, he could only start to fool with his impression: "After the grain blooms, some are male flowers and some are female flowers." When they grow pollen, they attract butterflies and bees. ”

"These little animals are crawling here and flying there, and their feet are covered in pollen. As long as the pollen of the male flower falls on the female flower, the grain can be harvested later. ”

"Of course, the ability of small animals to pollinate is limited after all, and most of the male and female flowers are very close to each other, and as long as the wind blows in the field, it is easy to pollinate by the wind."

"The process of pollination is equivalent to mating between plants."

After saying this, Chen Xu was already sweating profusely. In fact, he didn't know much about these things, and many of them were just casual nonsense, and even he didn't know how many mistakes he put in them.

If they had to dig deeper, I'm afraid he wouldn't have been able to answer.

Therefore, in order not to let everyone continue to ask, he hurriedly said: "We don't need to go into the details, as long as we can isolate the place where the good seeds are planted from other grain fields." ”

When he said this, the instructors of the agricultural branch of the miscellaneous branches, although they did not know much about it, still recorded the contents.

Perhaps when their notes are discovered thousands of years later, scientists will exclaim, "Oh my God, thousands of years ago, the ancients actually started studying biological science!" ”

Chen Xu didn't know if what he said was full of loopholes, he just wanted to inspire everyone so that they could cultivate better seeds.

After he returned from the expedition, he found that the traditional branch of Taixue was thriving, and the military branch was also impressive, only the miscellaneous branch was like a pool of stagnant water.

Wen Zhao was anxious in his eyes, and he always wanted to make the Miscellaneous Branches come alive.

Later, he gathered a group of blacksmiths and taught them to use coal and blast furnaces to make harder steel. Of course, he did not know the details of blast furnace steelmaking.

It's just that sometimes just one idea can change a lot.

After unremitting experiments, the use of coal for blast furnace steelmaking, and now there are finally some results. The quality of the weapons they have created is far greater than ever.

Of course, due to the lack of development of ancient technology, the grasp of the carbon content of steel is not accurate. Therefore, every time the steel is baked, their quality is also quite different.

Blast furnace steelmaking is actually pyrometallurgy, which uses the principle of coke to reduce metals, so that steel contains a large amount of carbon. Steel is an alloy and iron is an elemental substance.

In terms of performance, iron has low strength and hardness, but good plasticity and toughness. However, the role of steel is ever-changing due to the difference in carbon content.

Of course, if good steel is used to craft weapons, this skill is beyond the ages.

Chen Xu is planning that when the blast furnace steelmaking skills can be more mature, he will carry out a subversive replacement of the weapons of the soldiers in the territory.

And those tutors and students who have achieved something in this area have also been given knighthoods because of the breakthrough in blast furnace steelmaking. Chen Xu's move could not help but make many ministers of the DPRK and China oppose it.

However, Wen Zhao relied on his powerful power and insisted on his own opinions. Not only that, but he is also planning to give these people official positions.

The title and the reward of money make miscellaneous studies no longer cheap, and it marks that they can also become masters through their own efforts.

Many tutors and students in the branch were blushing because of this, and their enthusiasm was also mobilized.

During this period, Zhao Feng designed the Quyuan plow, in addition to the traditional plow handrail, but also more plough walls, plow arrows, plow evaluation, etc. The appearance of the Quyuan plough made it more convenient to cultivate the land, and Zhao Feng was also named the plough marquis.

Due to the emergence of Wen Zhao, the Quyuan plough appeared more than 300 years in advance, and the efficiency of the people in cultivating the fields became higher.

In addition, the medical branch of the Miscellaneous Branch School also came because of Hua Tuo's admiration, so that medicine began to flourish. For Hua Tuo, a miracle doctor, Chen Xu can be said to be overjoyed in the past.

In history, Hua Tuo hung the pot all his life to help the world, but he was unwilling to go out.

However, Chen Xu made it possible for those who studied medicine to become students, but it improved the status of medical workers, and if it was operated well, it could not make Chinese medicine have a revolutionary development.

Hua Tuo is reluctant to be an official, but he is willing to dedicate his life to medicine. Looking at the princes of the world, there is no one who attaches great importance to the development of medicine like Chen Xu.

It is precisely because of this that Hua Tuo came to Guanzhong and entered Taixue to teach.

After Wen Zhao led the troops back, he promoted Hua Tuo to become the vice president of the Miscellaneous Branch, and asked the military medical workers to take turns to go to Taixue to teach Hua Tuo medical skills.

In addition, he also recruited many children and taught them medical skills by Hua Tuo.

Nowadays, all the affairs of Guanzhong are on the right track, and it seems to be a little thriving. Chen Xu's position among the people is also extremely solid.

After some time, it was finally time to harvest the grain, and the people were very happy though they were busy every day.

At the court meeting on this day, someone suddenly said to Chen Xu: "Your Majesty is now eighteen years old, just at the age of pro-government, should the general give Your Majesty some rights, so that Your Majesty can slowly adapt to handling various government affairs?" ”

Someone took the lead, and the ministers of the DPRK and China naturally responded one after another, and they hoped that Wen Zhao could hand over the power in his hands, so that the Son of Heaven could govern himself.

On the main seat, Liu Xie also looked at Chen Xu with blazing eyes, hoping that he could agree.

In the past few years, Wen Zhao has treated Liu Xie well, and the Son of Heaven also has a good impression of Chen Xu, the general of the dynasty. However, as the Son of Heaven grows older, if Chen Xu always controls the military and political power, the contradictions between the two will be intensified sooner or later.

Caught off guard, Chen Xu was slightly confused by everyone. Fortunately, it didn't take long for someone to come out and relieve him.

I saw Li Ru come forward and said sharply: "Now that the princes are together, and the world is in turmoil, except for the generals, who can stabilize the Quartet?" ”

"The general is loyal to the Son of Heaven and works hard every day for His Majesty's country. Nowadays, all aspects of the territory are thriving, which is the best proof. ”

"Your Majesty, though he is over eighteen years old, has not experienced much wind and rain. It is foolish to think that the matter of His Majesty's pro-government can be postponed for a few more years. ”

With Li Ru taking the lead, the officials belonging to Chen Xu in the DPRK and China naturally made generous statements one after another.
