After a greeting, the group walked into the academy along the side door on one side of the gate. It was not that they didn’t want to enter through the main door, but now it is not the time to open the museum. According to ancient customs, the main door cannot be opened randomly at this time.

As for those tourists and scholars who were attracted by the movements here, they looked envious and curious at the wide open side door. It’s a pity that no one dared to do anything randomly, even if there was no one.

After the group entered the academy, they immediately found that the environment and scenery here were obviously better than outside. Not only were there fewer traces of locust plagues, but it was not an exaggeration to describe it as birds singing and flowers singing and beautiful mountains and rivers.

But the more this happens, the more regretful it is in Changsun Wuji's eyes. Such a good place is more than enough to be used by the Imperial College. As a result, the person in front of him is just used to teach the way of studying things, and just regret is considered very considerate.

Since I had already passed the academy's inspection tour in advance, after the group entered the academy, they soon got on several open tour buses coming in through the back door and started wandering at a speed that was not much faster than jogging.

Along the way, even with Changsun Wuji's experience, he could not help but be infected by the beautiful and pleasant environment and scenery around him. He stroked the long beard under his forehead and sighed: "This academy is such a good place."

"No matter how good the place is, it must be used properly to make sense. Otherwise, it would have become a place for people to play and play like outside." Li Anran, who knew that the literati of the Tang Dynasty was jealous of his academy, said with a intentional smile.

"Haha... the real person. I do think that this academy is too wasteful to teach the art of studying things. But I am sure that the big mind of using the real person as the country and the people will definitely make sense to do this." Changsun Wuji, who retreated from his original high position, said with a smile.

Li Anran has never explained anything about this issue. Before the academy was built, Changsun Wuji and others didn't care much about it, but not long after it was completed, they were attracted by the commercial street and commercial tax. After the commercial street and commercial tax were paid attention to, they were two huge things, drought and locust plague, and they couldn't take care of it at all.

Seeing that this historical celebrity who had retired from his position as a senior official, it was obviously because of Li Shimin's instructions to be responsible for the academy. Li Anran, who had not originally planned to hide anything, naturally would not miss this good opportunity to come to his door to help him.

"Shangshu Changsun, I believe you and the saints know the purpose of building this academy. As for why such a good academy is used to teach the art of investigating things, it is actually very simple, because the art of investigating things is the basis for the development of every civilization." Li Anran, sitting in the seat next to the other party, pointed to the scenery and buildings on both sides of the road, and said with a faint smile.

"Oh? I'd like to hear it carefully." At this point, Changsun Wuji hesitated for a moment, and then said, "True, since someone has already asked for the position of Minister of Pushe, please do not call someone the Minister of Shangshu in the future, and call him a certain sound auxiliary machine."

Although Changsun Wuji's name is Fuji, not everyone can call this title. Not to mention young juniors like Li Anran, even the few friends among his peers have the qualifications. Of course, Li Shimin, the king of a country, and those literary predecessors are naturally fine.

But considering that although the person in front of me looks very young and is indeed very immature from some of his actions and daily conversations, he cannot be judged by common sense with the identity of a real person in the upper realm. Therefore, in Changsun Wuji's eyes, it is still inappropriate to call him an auxiliary machine, but it is reasonable.

"Auxiliary machine?" Li Anran, who felt shocking in pronunciation of these three words, barely kept silent and said to him: "Okay, then I'll call him a loud voice."

"As for the technique of investigating things that I mentioned before is the basis of civilization development, it is actually very simple. Take the water truck and water well in my villa as an example, do you think these two items are beneficial to people's livelihood?"

"Water wheel? Water well?" Changsun Wuji, who was stunned for a moment, probably understood the meaning of this sentence, nodded and said, "How is these two things beneficial to people's livelihood? It is a blessing for the people of the world to promote it selflessly."

"I dare not say that I am lucky or not. I have my purpose in doing this." Li Anran, who waved his hand, said: "This water truck actually appeared as early as the Three Kingdoms period. If I really want to say it, I just improved it."

"But just this little improvement can use the water trucks that were originally used to transport water and irrigate to continue to produce mills, weaving workshops and other workshops. This little improvement has also greatly improved the production efficiency of these workshops."

"As for water wells, it is also easier to drill wells without the use of well-driving equipment. Just a simple pressure device and a well wheel can make the originally hard water withdrawal process simple and efficient."

"There is also the Quro Roof Plow. Just simply making appropriate changes to the old plow can greatly improve the efficiency of plowing fields. I believe that if this new plow and water wells and water trucks are adopted, if it were not for the locust plague, I believe that the auxiliary machine's Zhuangzi will have a great harvest this year, right?"

Faced with what someone said, Changsun Wuji didn't need to think too much, so he could clearly know that there was no falsehood in this sentence. Not to mention the waterwheel workshop in Xiaoyao Villa, just from the imitation results in his own village, he could verify the facts pointed out in the other party's words one by one.

"In fact, the auxiliary machine shows that this water truck is not my original creation. It has been recorded in the Wei Dynasty during the Three Kingdoms period. But this thing was not promoted until I appeared. What does this mean?"

"What does it mean?" Changsun Wuji asked.

"Whether a new technology emerges, it needs to meet three conditions to be accepted and promoted." Li Anran, who raised three fingers, smiled.

"I hope to hear it carefully." Changsun Wuji, who knew this was very important, said seriously.

"First, whether the technology is good or not is the key. Take this water truck for example. The water truck that appeared in the Wei Dynasty was also called a rollover, which is very different from the water truck I took out. Although it can also play a role in getting water, the effect is not good."

"Secondly, a good technology must adapt to different regions and needs if it wants to play its role. Take my waterwheel as an example, the location that can be used can be made into large, small, vertical, horizontal, tall, short, etc.."

"The third and most critical point is that a good technique must be taught by someone. But the old saying goes, teach your disciples to starve the master to death. In order to prevent them from starving to death, those who are masters will always keep a move just in case."

"It is actually not a mistake to say that this approach is actually. After all, it is inevitable that students are of varying quality. As the saying goes, if the law is not passed on easily, it is really easy to spread it so easily. If a bad one is easily caused by a lot of trouble."

"But many masters often care about this and that, which will directly lead to the loss of some originally good technologies. This is why water trucks appeared in the Wei Dynasty, but why they still couldn't promote them in the Tang Dynasty."

"This conservatism, in addition to not only failing to benefit more people, also hinders the further development of technology. As I said before, the water trucks in the Wei Dynasty were much worse than those used in the villages in transporting water and irrigation."

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