After exchanging pleasantries, the group of people walked into the academy along the side door of the main gate. It’s not that they didn’t want to enter through the main entrance, but it’s just that it’s not the opening time yet. According to ancient customs, the main entrance cannot be opened randomly at this time.

.

As for the tourists and scholars who were attracted by the movement here, they all looked at the wide open side door with envy and curiosity. It's a pity that, let alone Changsun Wuji, he was there.

No one dares to mess around.

After the group entered the academy, they immediately discovered that the environment and scenery inside were obviously better than outside. Not only were there fewer traces of the locust plague, but the description of birds singing, flowers fragrant, and mountains clear and clear water was no exaggeration.

But the more this happened, the more regretful he felt in Changsun Wuji's eyes. Such a good place was more than enough for the Imperial College. But in the end, the person in front of him was only used to teach the way of studying things. It was just a pity.

It’s very honorable.

Since they had already passed through the academy for today's inspection trip, after the group entered the academy, they quickly boarded several open tour buses that came in from the back door, and started walking in a way that was not much faster than jogging.

The speed picked up.

Along the way, even with Changsun Wuji's experience, he couldn't help but be affected by the beautiful and pleasant environment and scenery around him. Then he stroked his long beard under his forehead and said with emotion: "This academy is really a good place.

"

"No matter how good a place is, it has to be used properly to be meaningful. Otherwise, it will become a place for people to play and have fun just like the outside." Li Anran, who knew that the literati of the Tang Dynasty coveted his academy, deliberately

Said with a smile.

"Haha... Zhenren. I do feel that this academy is used to teach those skills of studying objects. But I am convinced that with Zhenren's broad mind for the country and the people, there must be a reason to do this." From the original

Changsun Wuji, who had retired from the high position, said with a smile.

Regarding this issue, Li Anran really never gave a good explanation. Before the academy was built, Changsun Wuji and the others didn't pay much attention to it. However, not long after it was completed, it was blocked by the commercial street and commercial tax.

It attracted attention. After paying attention to the commercial street and commercial taxes, drought and locust plague were two huge things that couldn't be taken care of at all.

Looking at this historical figure who resigned from a high-ranking official position, it was obvious that he must have been ordered by Li Shimin to take charge of the affairs of the academy. Li Anran, who had no intention of hiding anything, naturally would not miss this kind of help coming to his door.

Chance.

"Changsun Shangshu, I believe that you and the sage are clear about the purpose of building this academy. As for why such a good academy is used to teach the art of studying objects, it is actually very simple, because the art of studying objects is the foundation of the development of every civilization." Sitting there.

Li Anran, who was sitting next to the other party, pointed at the scenery and buildings on both sides of the road and said with a slight smile.

"Oh? I'd like to hear the details." At this point, Changsun Wuji hesitated for a moment, and then said: "Master, since someone has resigned from the post of minister of servants, you should not call someone a minister or call someone a person in the future.

One auxiliary sound."

Although Changsun Wuji is nicknamed Fuji, not everyone can pronounce this title. Not to mention young juniors like Li Anran, there are only a few close friends among his generation.

Only good friends have that qualification. Of course, as the king of a country, Li Shimin and those literary seniors will naturally have no problem.

However, considering that although the person in front of him looks very young, and is indeed very immature in terms of some of his methods of doing things and his daily speech, after all, he has the identity of a real person in the upper realm and cannot be judged by common sense.

Therefore, in the eyes of Changsun Wuji, although it is still inappropriate to call himself auxiliary machine, it is still reasonable.

"Auxiliary machine?" Li Anran, who found the pronunciation of these three words together very shocking, managed to remain calm and said to her, "Okay, then I'll call you auxiliary machine.

"

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

"Waterwheel? Well?" Changsun Wuji, who was just stunned for a moment, roughly understood the meaning of these words, nodded and said: "These two things are of great benefit to people's livelihood, they are of great benefit! If a real person can selflessly promote them, they will really benefit the world.

The blessings of the people.”

"I dare not say whether I am blessed or not. I have my own purpose in doing this." Li Anran waved his hand and said: "This waterwheel has actually appeared as early as the Three Kingdoms period. Is it really necessary?

Speaking of which, I just improved it."

"But just this improvement allowed us to use the waterwheels that were originally used to transport water and irrigate to continue to develop mills, weaving mills and other workshops. And this improvement has also improved the production efficiency of these workshops.

Improved exponentially.”

"As for water wells, it is much easier to dig wells without the equipment. Just a simple pressure device and a well reel can make the originally laborious process of fetching water simple and efficient."

"There is also the Nagqu shaft plow. Just by making appropriate changes to the old plow, the efficiency of plowing can be doubled. I believe that with the use of this new plow and the water well water truck, if it were not for the locust plague, I believe that the auxiliary

Is it true that Zhuangzi will have a bumper harvest this year?"

Faced with what someone said, Changsun Wuji didn't need to think too much to know clearly that there was no falsehood in it. Not to mention the waterwheel workshop in Xiaoyao Villa, just from his own

The results of the imitation in Jiazhuangzi can one by one confirm the facts pointed out in the other party's words.

"Actually, we can tell that this waterwheel is not my original invention. It has been recorded as early as the Wei Dynasty during the Three Kingdoms period. But this thing was not popularized until I appeared. What does this mean?

?”

"What does it mean?" Changsun Wuji asked.

"When a new technology appears, whether it can be accepted and promoted, it needs to meet three conditions." Li Anran raised three fingers and said with a smile.

"I would like to hear the details." Changsun Wuji said seriously, knowing that these words were very important.

"First, good technology is the key. Take this waterwheel as an example. The waterwheel that appeared during the Wei Dynasty was also called a rollover. It is very different from the waterwheel I took out, although it can also play a role in collecting water.

, but the effect is not very good.”

"Second, if a good technology wants to play its role, it must adapt to different regions and needs. Take my waterwheel as an example. It can be made into large or small ones wherever it can be used.

Vertical, horizontal, tall, short, etc.”

"Third, and the most critical point, a good technique must be taught by someone. But as the old saying goes, the disciples will starve to death. In order to prevent themselves from starving to death, those masters will always

I’ll keep one handy just in case.”

"It is not wrong to say that this approach is actually not wrong. After all, students are inevitably mixed, and as the saying goes, the law is not taught lightly. If it is spread so easily, a bad one can easily cause many problems.

Big trouble."

"But often many masters are worried about this or that, which directly leads to the gradual loss of some originally good skills. This is why waterwheels appeared as early as the Wei Dynasty, but why they still couldn't be promoted in the Tang Dynasty.

It’s because of the opening.”

"And this kind of conservatism, in addition to being unable to benefit more people, also hinders the further development of technology. As I said before, the waterwheels of the Wei Dynasty were better than you and me in terms of transporting water for irrigation.

It’s much worse than what I used above.”

"Not to mention the waterwheel we use, in addition to these two basic functions, it can also be used in mills, weaving mills and even blacksmith workshops. Just like the most primitive writing, it has become more extensive and profound today.

Same thing."

"The sage once asked me whether secular people could learn to make magic weapons such as electric cars. I didn't answer at the time. Now I can give you a clear promise. Not only can it be done, but it can also be done.
