After exchanging pleasantries, the group walked into the academy through the side door on the side of the gate. It's not that I don't want to enter through the main entrance, but it's not the time to open yet, and according to ancient customs, the main entrance can't be opened at this time.

As for the tourists and scholars who were attracted by the movement here, they all looked envious and curious when they looked at the wide open side door. It's a pity, not to mention that there is the eldest grandson Wuji, even if there is none, no one dares to mess around.

After the group entered the academy, they immediately found that the environment and scenery inside were obviously a little better than the outside. Not only are there many fewer traces of the locust plague, but it is not an exaggeration to describe it as a song of birds and flowers, and beautiful mountains and rivers.

But the more this is the case, the more regretful it is in the eyes of the eldest grandson Wuji. Such a good place is more than enough for the Guozijian to use. As a result, the person in front of him is just used to teach the way of things, and it is already very face-saving just to regret it.

Since they had already passed the academy's inspection trip for today, after the group entered the academy, they quickly got into a few open tour buses that came in through the back door, and spun around at a speed that was not much faster than jogging.

Along the way, even with the experience of the eldest grandson Wuji, he couldn't help but be infected by the beautiful and pleasant environment and scenery around him. At the moment, he stroked the long beard under his forehead and said with emotion: "This academy is really a good place." ”

"No matter how good the place is, it must be used properly to make sense, otherwise, it will become a place for people to play and play just like the outside." The group of literati who knew the Dao Datang Dynasty coveted Li Anran of their academy, and said with a smile intentionally.

"Huh...... Reality. I really felt that this academy was too violent to teach those martial arts. But I am sure that with a big mind of real people for the country and the people, there must be a reason to do so. The eldest grandson Wuji, who had retired from his original high position, said with a smile.

Regarding this problem, Li Anran really hasn't explained anything well. Before, when the academy was not built, the eldest grandson Wuji and they didn't pay much attention to it, but not long after it was built, they were attracted by the commercial street and commercial taxes. After the commercial street and commercial tax were concerned, it was the drought and the locust plague, which were two big things, and they couldn't be taken care of at all.

Looking at this historical celebrity who stepped down from his position as a high-ranking official. Obviously, he should have been instructed by Li Shimin to take charge of the affairs of the academy. Li Anran, who originally didn't plan to hide anything. Naturally, I won't miss this good opportunity to help myself.

"Eldest Sun Shangshu, I believe that the purpose of my construction of this academy is clear to you and the sage. As for why such a good academy is used to teach the art of Gewu, it is actually very simple, because the art of Gewu is the foundation of the development of every civilization. Li Anran, who was sitting on the seat next to the other party. Point to the scenery and buildings on both sides of the road. Said with a light smile.

"Oh? I would like to hear about it. "Speaking of which. The eldest grandson Wuji hesitated for a moment, and then said: "Zhenren, since a certain person has asked for the dismissal of the servant shooting Shangshu. In the future, please don't call a certain Shangshu anymore, call a certain auxiliary machine. ”

To say that although this eldest grandson Wuji is a word auxiliary, this title is not something that anyone can shout. Not to mention a young junior like Li Anran, even among the few close friends among his generation, only have that qualification. Of course, as the king of a country, Li Shimin, and those predecessors in the literary world are naturally no problem.

But considering that although the person in front of him looks very young, and he is indeed very immature in terms of some means of acting and daily speech, after all, he is a real person in the upper realm, and he can't live it with common sense at all. Therefore, in the eyes of the eldest grandson Wuji, although it is still inappropriate to call himself an auxiliary machine, it can also be said.

"Auxiliary, huh?" Li Anran, who was very shocked by the reading of these three words together, reluctantly kept quiet and said: "It's okay, then I'll call it an auxiliary machine." ”

"As for what I said before, this art of learning is the foundation of the development of civilization, it is actually very simple. Take the waterwheel and well of my villa as an example, do you think these two items are beneficial to people's livelihood? ”

"Water wheels? Water well? Just stunned for a moment, the eldest grandson Wuji, who roughly understood the meaning of these words, nodded and said: "How beneficial are these two things to people's livelihood, there are great benefits!" Real people can selflessly promote, which is really a blessing for the people of the world. ”

"I dare not say that I am blessed or not, I also have my purpose in doing this." Li Anran, who waved his hand, said: "This waterwheel has actually appeared as early as the Three Kingdoms period, and I just improved it." ”

But this improvement alone made it possible to continue mills, weaving mills, and other workshops using waterwheels that were originally only used to transport water and irrigate. This improvement has also doubled the productivity of these workshops. ”

"As for wells, too, it is much easier to drill wells without the equipment used to drill wells. Just a simple pressure equipment and a well wheel can make the otherwise painstaking process of water intake simple and efficient. ”

"And the curved plow, just a simple change to the old plough can make the efficiency of ploughing exponentially. I believe that with this new plough and the well water wheel, if it weren't for the locust plague, I believe that the auxiliary Zhuangzi would also have a bumper harvest this year, right? ”

In the face of what someone said, Eldest Sun Wuji didn't need to think about it, he could clearly know that there was no falsehood in Lu Dao's words. Not to mention the waterwheel workshop in Xiaoyao Villa, just from the imitation results in his own Zhuangzi, he can prove the facts pointed out in the other party's words one by one.

"Actually, it can be seen that this waterwheel is not my original creation, and it has been recorded as early as the Wei Dynasty during the Three Kingdoms period. But it didn't spread until I came along, so what does that mean? ”

"What does that mean?" Eldest Sun Wuji asked.

"The emergence of a new technique, whether it can be accepted and promoted, needs to meet three conditions." Li Anran, who raised three fingers, said with a smile.

"I want to hear about it." Knowing that this is very important, the eldest grandson Wuji is right.

"First, whether the technique is good or not is the key. Take this waterwheel as an example, the waterwheel that appeared during the Wei Dynasty is also called a rollover, which is very different from the waterwheel I took out, although it can also play a role in taking water, but the effect is not good. ”

"Second, if a good technique wants to play its role, it has to adapt to different regions and needs. Take my waterwheel as an example, it can be used at all, and it can be made into large, small, vertical, horizontal, tall, short, and so on. ”

"Thirdly, and most crucially, a good technique must be taught by someone who is willing to teach it. But as the old saying goes, the apprentices of the church starve to death the master, and in order to prevent themselves from starving to death, those who are masters will always keep a hand just in case. ”

"It's not wrong to say that this is actually a practice, after all, it is inevitable that there will be good and bad when you are a student, and as the saying goes, the law is not passed on lightly, if you really want to spread it so easily, a bad one is easy to cause a lot of trouble."

"But often many masters blindly scruple about this and that, which directly leads to the gradual loss of some originally good skills. This is also the reason why the waterwheel appeared as early as the Wei Dynasty, but it was still impossible to promote it in the Tang Dynasty. ”

And this conservatism, in addition to not being able to benefit more people, also hinders the further development of technology. As I said before, the waterwheels of the Wei Dynasty were much, much worse than those used in Zhuangzi in terms of carrying water for irrigation. ”

"Not to mention the watermills we use, in addition to these two basic functions, they can also be used in mills, weavers and even blacksmiths. Just as the most primitive writing has developed to this day, it has become more extensive and profound. ”

"When the sage asked me if secular people could learn to make ritual objects such as electric cars, I didn't answer at the time. Now I can give you a clear promise that you can not only do it, but you can do it better! (To be continued......)
