Cao Zhi originally did not plan to let Yang Xiu teach these refugees how to read. This was really a little overkill. Therefore, Cao Zhi's idea was to let Yang Xiu gather scholars.
On the other hand, when these scholars came here and heard about the mission Cao Zhi had given them, they did not have any objections. With their knowledge, they could teach these commoners how to read and write. At the same time, Cao Zhi also sent a message that they would teach these refugees to ask Yang Xiu if they didn't know anything. If they taught well, Cao Zhi would even give them official positions. This time, their enthusiasm for teaching was immediately inspired.
Among these scholars, most of them were from poor families, merchants, or young masters of small aristocratic families. They did not have the opportunity to come into contact with a great scholar like Yang Xiu at all. Now that they had the opportunity to receive Yang Xiu's guidance, each and every one of them squeezed their heads out to come over. After all, the opportunity to receive education from the burly man was really too rare!
Especially when Cao Zhi said that if they taught well, they could become officials. They really went crazy.
Oh my god, this was a good opportunity to reach the heavens in one step. Could it be that a pie fell from the sky and landed on his face?
As a result, all of their enthusiasm was aroused. Each of them taught the refugees with all their heart and soul. When they were angry, they would even take out small whips to whip them. However, they soon realized that it was not easy to make whips, and they were easy to break. Therefore, they also developed the ferule.
Seeing that they were able to invent the ferule on their own and listening to the incessant screams of the refugees every day, Cao Zhi couldn't help but think back to his youth and felt a burst of amusement and gratification.
What Cao Zhi had set up now was the most basic subject-Pinyin. Although this thing was very novel, it was indeed very useful and not difficult to learn. Moreover, this novel teaching concept and train of thought shocked Yang Xiu. It was as if he had discovered a new continent. Yang Xiu studied Pinyin day and night. In the end, Yang Xiu only used less than two weeks to completely master it. Adding on the torture of teaching others, it also took less than a month. All the scholars were already familiar with the novel teaching method of Pinyin.
Seeing their progress, Cao Zhi couldn't help but feel surprised. After the real assessment, he realized that they had really mastered it completely. Cao Zhi couldn't help but sweat. Thinking about how he had used three years to learn it, he couldn't bring himself to say it.
In addition to the implementation of Pinyin, Cao Zhi also did something that made Yang Xiu and the other scholars feel refreshed, and that was the promotion of paper.
As everyone knew, the paper was made by Cai Lun of the Eastern Han Dynasty. Cai Lun was from Guiyang and had once been in charge of the imperial utensils. In his spare time, he used tree bark, hemp, rags, and fishing nets. After a series of processes such as kneading, pounding, copying, and drying, he created paper, which was later named "Cai Hou Paper". After this paper was made, it was presented to Emperor Han He in the 17th year of Yongyuan. However, although this paper was made, it was not widely promoted because of the rough texture of the initial paper and the extremely complicated process needed to be carried out to make it delicate. Therefore, it was only circulated among some high-ranking officials and nobles. Most people still used bamboo slips and silk as their main writing materials.
Cao Zhi clearly remembered that this situation lasted until the Jin Dynasty, when the technology of paper making was spread to the Yangtze River basin. It relied on the rich raw materials for paper making to produce better paper, and then it was widely promoted. The popularity of copying books and collecting books in the Jin Dynasty was due to the popularity of paper.
In fact, it was precisely because Cai Lun's paper was optimized and popularized in the Jin Dynasty that culture flourished and developed rapidly. Culture could no longer be monopolized, which indirectly led to the emergence and implementation of the imperial examination system in the Sui Dynasty. However, these were all things to talk about later, so he temporarily skipped them.
Although Cao Zhi knew about the era when paper was popular and the simple manufacturing process, he had no idea how paper was actually made.
However, at this moment, Cao Zhi remembered his golden finger, the all-purpose notebook. He tried to search on it, and sure enough, the specific manufacturing process of the paper appeared. Even the time and materials were clearly marked. It was a complete strategy for making paper!
Cao Zhi was overjoyed. With this paper-making guide, the quality and speed of the paper he made would be greatly improved. Thus, he immediately decided to call Ding Yi, who was assisting Yang Xiu in building the Great Wei Academy, over and let him be in charge of making paper.
Of course, just making paper was not enough. Thinking of this, Cao Zhi slapped his forehead and used his notebook to find out the specific operation of movable type printing. Then, he made a printing guide and handed it to Ding Yi to be responsible for printing books. It was used by the Great Wei Academy.
When Ding Yi received Cao Zhi's order, he did not understand it at first. However, after he personally implemented it and realized the practicality of these two strategies, his eyes lit up. He, who was already extremely intelligent, instantly realized the importance of Cao Zhi's actions, so he gladly accepted the order and went.
Apart from that, after Cao Zhi finished all this, he gradually began to realize his cheat. He then took out potatoes and sweet potatoes from his backpack.
If Cao Zhi's memory was correct, potatoes and sweet potatoes would only be introduced to China a thousand years later. The people of the Great Han Dynasty had never seen these two crops before.
This allowed Cao Zhi to see a broader business opportunity.
There was no doubt that potatoes and sweet potatoes were crops that could be produced on a large scale and could fill hunger. They were the same as wheat and rice. The key was that not only did they taste good, but the conditions and methods required to grow them were not very difficult. They did not need to be of a high standard at all.
If these two crops could be planted, not only could they solve the problem of food and clothing for the Cao army, but they could also widely trade with the outside world and obtain extremely huge economic benefits!
Cao Zhi looked at the potatoes and sweet potatoes in his hands as if he was holding a pearl. These things that didn't seem to be worth much in his hands were treasures that contained huge wealth in this era!
Each potato and sweet potato represented countless granaries and copper coins!
Cao Zhi was extremely excited. He personally dug the soil and planted these potatoes and sweet potatoes. He would go to the fields every day to pull weeds, apply fertilizer, and observe their growth.
Cao Zhi's actions caused the villagers who did not understand the situation to tear up. They all rushed to tell him,""Young Master Zhi is a man of his word, personally farming the fields and experiencing the lives of us poor farmers. He is truly a good young master that is once in a blue moon!”
