In history, Xu Guangqi discovered sweet potatoes and vigorously promoted them until 1624, at this time he didn't know what sweet potatoes were, and he was very puzzled when he saw Guo Zhiyuan staring at him, and couldn't help touching his face and asked: "Childe, but I have a foreign body on my face?" Why are you staring at me like that? ……”

Guo Zhiyuan laughed, with Xu Guangqi, the pioneer of promoting sweet potato planting, he is worried that sweet potatoes can not be successfully promoted and planted in Gutian, as long as sweet potatoes are successfully promoted and planted, the problem of food shortage will be basically solved, and it is best to get corn and potatoes as well, so that Gutian's grain crops will be rich enough.

Thinking of this, Guo Zhiyuan waved his hand excitedly and said: "Sir, I have already thought of a way to solve the problem of food shortage, but I will have to work hard when the time comes!" ……”

Xu Guangqi was a little inexplicable, how could Guo Zhiyuan find a way to solve the food shortage so quickly? This is a big problem that has plagued the entire Ming Dynasty for many years, and he hurriedly chased after him to ask, but Guo Zhiyuan refused to say, only that he would naturally know when the time came.

When he returned to the county office, Guo Zhiyuan immediately called Zhang Cheng and asked him to go to the vicinity of Changle, Fujian Province to inquire about the news of sweet potatoes, and drew the general appearance of sweet potatoes and sweet potato leaves, and asked him to find them according to the map.

The Spring Festival passed quickly, the Lantern Festival passed in the blink of an eye, Guo Zhiyuan's road repair plan was about to be put on the agenda, in fact, Sun Chuan seemed more anxious than him, and he took the opportunity to give him New Year's greetings to urge him several times, so after the Lantern Festival, Guo Zhiyuan gathered the Justices of the Peace to discuss the matter of raising funds to repair the road, as soon as he heard that the road was going to be repaired, Chen Huaili jumped up and shouted: "Don't look for the old man for this kind of thing, the old man is not interested in ......", after speaking, he directly brushed his sleeves and left.

Although the other justices of the peace did not leave, they were obviously not very optimistic about Guo Zhiyuan's road construction plan, and in the end, only three justices of the peace (including Sun Chuan) expressed their willingness to participate in Guo Zhiyuan's road construction plan, and Guo Zhiyuan did not seem too disappointed in this regard, because he knew that these left justices of the peace would definitely regret it in the future.

Road construction, quality must be the first, like those YY through the main characters in the novel are a pat on the head to make cement, and even some even asphalt concrete pavement have come out, Guo Zhiyuan is not so capable, so he decided to use "Sanhe soil" plus gravel to pave the road, "Sanhe soil" is to use hydrated lime, clay, fine sand three materials according to a certain ratio to mix and then tamp and roll forming, although its strength is worse than cement concrete, but the strength is also very high, and has a certain water resistance.

The technology of "Sanhe soil" has been in ancient China for a long time, but it is mainly used to repair houses and city wall buildings, and there are also glutinous rice juices added to Sanhe soil, and the houses built are even stronger than cement concrete, but they are rarely used to build roads, mainly because of the complex process and high cost.

So at first, Sun Chuan and the other two justices of the peace did not agree to use Sanhe soil to build the road, and finally Guo Zhiyuan persuaded them that since the future will be charged, the quality of the road must be excellent, otherwise those passing merchants must have complaints, and if the quality is not too hard, it is always necessary to repair, and the maintenance cost will only be higher, fortunately, there are many stones in Gutian Mountain, lime and gravel can be taken from local materials, and water resources are also abundant, the main stream of the Minjiang River will pass through Gutian, and the river sand mining is also easy. So in general, the cost of building roads is still much lower than that of modern times.

Then it is to recruit people's husbands, the fundamental purpose of Guo Zhiyuan's road construction is to solve the employment problem of the landless people, and at this time it is the agricultural slack season, naturally it is a hundred responses, and the recruits gather, plus the people of the neighboring counties have heard that the bandits in Gutian are now cleared, but the bandits in the county where they are located are becoming more and more intense, and many people simply fled to Gutian, at this time the household registration management of the Ming Dynasty has been very chaotic, many of them are black households, Guo Zhiyuan is also a person who does not refuse, Let Xu Guangqi lead people to re-register these displaced people, and in just one month, the population of Gutian County has increased by several thousand, and a steady stream of displaced people have rushed to Gutian to settle down.

In order to rush the progress, Guo Zhiyuan requisitioned a total of more than 3,000 people, divided into ten sections of simultaneous construction, plus Zhao Shizhen's workshop, the county school expansion, a total of nearly 5,000 people, Gutian County set off a wave of construction, everywhere is a hot scene!

Guo Zhiyuan was so busy every day that his feet were not on the ground, constantly inspecting various construction sites, solving various problems, and running down his feet all over the day, but Guo Zhiyuan did not feel bitter at all, watching Gutian County change every day under the boom of large-scale construction, his heart was full of a sense of achievement.

However, this sense of accomplishment did not last long, because Xu Guangqi told him that he had no money again! This road repair is really too expensive, not to mention anything else, just 5,000 people a day to eat, drink and lasa The money and food spent is not a small amount, during this time, Guo Zhiyuan spent money like flowing water, and the silver he seized when he copied the leopard's nest has been almost spent, but fortunately, Leng Xianning heard that he needed money to build the road, so he made a special trip to send him 10,000 taels of silver tickets, saying that it was the profit dividend of Miaoyifang that was advanced in advance, so it could barely be maintained.

But this is not the way to go on after all, Sun Chuan has come to the door several times to complain, saying that he should not use Sanhe soil to pave the road, resulting in a significant increase in the road construction budget, and even he, a rich man, feels unbearable. Therefore, Guo Zhiyuan must find a new way to make money in order to ensure that his road construction plan will not be abandoned halfway.

What is the way to make money quickly and with high profits? Guo Zhiyuan grabbed his hair with a headache again, as a traverser, he naturally has no shortage of ideas to make money, but things that are too ahead of this era are not easy to make, but even if they can be made, he doesn't dare to take them out easily, this is like a child, you give him an Apple X mobile phone and let him take it to the street, it will definitely not be long before the phone will be robbed, and he will have to be beaten up, Guo Zhiyuan's current power is still very weak, and he is no different from a child in front of those big people, At this time, creating too many things that do not belong to this era is not a good thing for him, but it will become a way to take trouble!

The more Guo Zhiyuan thought about it, the more upset he became, whenever he encountered this kind of annoyance that he couldn't think of a solution to break his head before the crossing, he couldn't help but smoke a cigarette to relieve the anxiety in his heart, at this time he couldn't help but put his hand into his pocket and made a cigarette action, which naturally took out an empty one, but it made him have an idea in his mind!
