Chapter 5 Gon Xue

The river is getting more and more rapid, and the small river cuts the rocky mountains out of deep V-shaped canyons. It's hard to imagine that a canyon with a drop of several hundred meters was washed away by this weak and not even fixed shape of water.

"Time has the power to be quiet." The eldest grandson muttered to himself.

The plank road has been washed over the years, and some of the planks have begun to decay, and along the way, workers have removed the rotten planks and replaced them with new pine planks. Most of the plank roads are without guardrails, with cliffs on one side and an abyss on the other. Workers don't even use ropes to toss and turn on the cliff face, and if they are not careful, they will fall.

This section of the plank road is also known as the Shimen plank road, because people have carved a tunnel of several meters in the stone. Later generations of the eldest grandson came here, but by then it had become a scenic area, and the real stone gate was submerged under the reservoir, and people re-excavated a section for people to visit.

Walking here, the slope is basically finished. Even if he didn't experience those things, Changsun Tang felt that he had a new idea, traveled thousands of miles, read thousands of books, and the words of the ancients still made sense.

There are many allusions about the Bao Chuan Road, most of which happened before the Three Kingdoms. The famous Bao Xi who smiled at the world was the Bao Guo people in the Spring and Autumn Period, and the location of the Bao Country was at the entrance of the Bao Slope; The plank road of the Ming plank road and the darkness of Chen Cang also refers to this plank road. Bao Guo and Bao Xi are both things in the pile of old papers, and most of the plank roads in the Ming Dynasty are also passed down among literati and ink writers. However, Cao Cao's expedition to Hanzhong left the famous word "Gunxue" here.

At this moment, the eldest grandson was staring at the two Han Li's two Han Li, who were carved on the boulder. Legend has it that Cao Cao marched here, saw the white waves rolling like snow, and wrote these two words. Left and right said that this is a single word, "Gong" is missing three points of water, Cao Cao pointed to the Baohe River and laughed and said that there is no water here. So he ordered someone to engrave two words on the stone.

At that time, the details were not examinable, but the eldest grandson had different ideas when he came here, which was a loss that Cao Cao did not have a language teacher, and he did not need to take the college entrance examination, otherwise he would not be able to write these two words.

Out of the Bao Valley, a fertile field suddenly appeared in front of the three of them, without any warning, and the plain of the Hanshui Valley appeared. In later generations, the Hanshui Valley at this time should be a rapeseed and seedling field that is about to be harvested. At this time, rice had not yet been popularized on a large scale in this area. In the fields of wheat that are about to ripen, the wheat has already bent down. The eldest grandson of the previous life was born in the countryside, and he had seen the wheat fields of the later generations, but he frowned when he looked at the wheat fields here, and the uneven wheat in the wheat fields indicated that the yield per mu of this field was about 200 catties, and the gap between the yield per mu of the later generations was too big.

"Uncle, how is this year's harvest?" The eldest grandson asked the old man who was resting on the side of the road. The old man, like most ordinary peasants, had a bronzed face, the wrinkles on his face were carved by the carving knives of the years, and a thin shirt was covered with patches, and in some places the patches continued to be patched. The old man worked barefoot in the field, and a pair of neatly arranged straw sandals lay on the ridge not far away.

"It's okay, I haven't had such a good time in some years." It seems that the old man is also a talkative person.

"When I was young, it was probably two or three years of great business, and the wind and rain were good every year, although there was less land, but the harvest was still good. Last year, there was a drought and some poor harvests, but this year is not bad, and I estimate that I can collect about five stones from this land. Seeing that the harvest was about to be harvested, the old man went down to the field to take a look. Changsun Tang estimated that this land is about two and a half acres, that is to say, in a good year, Datang is supporting the country with a yield of 200 catties per mu. In the past, I didn't feel anything when I was studying, but now when this jagged wheat stands in front of me, I realize the difficulty of farmers and the reason why ancient dynasties attached importance to agriculture.

Legend has it that Cao Cao ordered that the farmland should not be destroyed during an expedition, and the offender was beheaded, but his horse was frightened by the birds and destroyed the farmland, so Cao Cao cut off a few strands of hair to show that he was leading by example. If this story does not allude to politics, it can reflect the importance that ancient rulers attached to agriculture.

"And what will be planted after this harvest?" Changsun Tang doesn't know if the planting method of more than one season has begun to be promoted in Hanzhong.

"Seedling!"

"Seedlings? Rice? Is there water here? ”

"I don't know what kind of rice it is, but if you look at the location of the field, there is a canal not far from there, and last winter the government just organized us to build a dam in the Bao River to bring water over, and the seedlings have already been put on the seedlings, so we will plow the field and plant the seedlings when the wheat is harvested. It's still been a good two years, I don't have to fight, and my two sons are also helping at home, so there is hope for this day. The old man seemed to be showing off, even if the war in the late Sui and Han dynasties was not much, there were still not many people who could eat enough food to eat, and even in the last years of the Great Cause and the early years of Wude, the whole family went to the Qinling Mountains to hide for a while.

After chatting for a while, the old man took his leave and went home, put on his straw sandals, and carried a basket full of wild vegetables to go home for breakfast. The eldest grandson looked up at the noon sun, but he also knew that most families still had two meals a day, breakfast at about ten o'clock, and lunch at three or four o'clock in the afternoon.

At this time, agricultural production is basically on the right track, and there will not be much progress if there are no particularly big changes, and there are only two aspects of this big change at present. One is the problem of seeds, when the eldest grandson came to this world, except for buying some coarse chili noodles to prepare fried oil chili peppers because he likes to eat chili peppers, there are no other seeds, but the high-yield corn and potatoes and sweet potatoes are far away in the Americas, maybe the current navigation technology can be reached on the basis of not considering the cost and price, but that requires time and a lot of resources, which happen to be not available to themselves; The second is chemical fertilizer, which can contribute more than 40% to output, but this needs the support of the chemical industry.

In ancient times, everything was not as simple as we imagined, just like this time from Chang'an to Hanzhong, I walked intermittently for nearly two months, even if I was at full speed at least about a week, and in the future, three hours was enough to take the high-speed. The development of agriculture is a truth, not that the ancients were not smart enough, nor were they lazy, but that they were limited by the times. Changsun Tang intends to change all this, but it took two or three hundred years from the great discovery of navigation to the industrial revolution in the West, and even if a traveler knows the direction of the future, it is impossible to complete all this without fifty years.

When he first crossed over, Changsun Tang felt that he could build a steam engine train in ten years, but after six years, he had roughly understood that this was simply a matter of paper talk. Why? He read an article about crossing before he crossed, and the protagonist repelled several enemy attacks with magnesium light bullets, which is okay, the question is where did your magnesium come from? You must know that Napoleon's cutlery for others with silver was made of aluminum himself, and magnesium is more difficult to refine than aluminum. It's all a big systems project.

If the eldest grandson wants to develop, the Ministry of Agriculture may want to make a gesture like Cao Cao.

All this is like the boiling water of the Bao River, which can cut through the abyss but takes time, and the strength of the individual is too small and insignificant compared to this.
