In the smooth carriage, Li Su and Yuan Tiangang sat opposite each other, and on the low table in the middle, there was a teapot and two teacups, and the tea in the cup floated out a misty water vapor, which dissipated in the air in the blink of an eye.

"Daoist Yuan, why are you in such a hurry to come to me?" Li Su sipped the tea and asked very casually. Originally, because of Yang Jun's affairs, he doesn't usually go out at all these days except for visiting some important elders, of course, this is also the reason why his group of fox friends are not there, Cheng Huailiang, Li Yong and others are all in the military academy, and they can't come out at all, while Yan Bei and Li Jingheng and others stay in Taiwan to reclaim the plantation, and they don't know when they will come back?

"Hehe, Your Highness, don't worry, you'll know when you get to the Dao Academy." Yuan Tiangang stroked the three strands of long beard on his chest with his hand, and said with the appearance of a master outside the world.

"Haha, I didn't expect Old Immortal Yuan to also learn to sell Guanzi!" Li Yu laughed and said, but since Yuan Tiangang was unwilling to say, he didn't ask anymore, and instead asked about other things, "Daoist Yuan, how far has your Daoist Academy developed now, have you researched some products that can be industrially produced?" ”

As soon as he heard Li Su ask about the development of the Taoist Academy, Yuan Tiangang immediately raised his eyebrows, and even said with some radiance: "Your Highness doesn't know, since the opening of our Taoist Academy in February this year, we have recruited 5,000 formal students, and as for the teachers who teach, I have also invited nearly 200 Taoist friends who are profound in Taoism to take on the role, and the teaching materials are also being improved, and the entire academy is on the right track!" ”

Li Su was also overjoyed when he heard this, and said happily: "Daoist Yuan is really worthy of being the first person in Daomen, he can gather so many teachers and students in a short period of time, and after a few years, as soon as these students graduate, they will definitely be able to bring the traditional Taoism of the Central Plains to a higher level!" ”

Although Yuan Tiangang usually looks detached from the world, he still has an obsession with carrying forward Taoism in his heart, so he is so interested in Taoism. Now when I heard Li Su's congratulations, I was naturally very happy, but I still said a few words modestly.

"That's right. Daochang Yuan, I wonder how many of these teachers and students you recruited are responsible for studying chemistry? Although Li Su is concerned about the development of Taoism, what he is most concerned about is the chemical industry developed by the Taoist Academy.

"Hehe, although Your Highness can rest assured, I have naturally not forgotten the matter of chemistry, but the establishment of the Dao Academy is still short. So there is no clear division of labor yet. Therefore, in the teaching of the Taoist Academy, in addition to learning various Taoist classics, the other is the chemical foundation provided by Your Highness, as well as the chemical experience summarized by our Taoist people. After one year of teaching, the college will allow these students to choose their main direction of study according to their interests. So you're asking this question a little early!" Yuan Tiangang replied with a smile.

Li Su also felt justified when he heard it, interest is the best teacher, the Taoist College recruited 5,000 students in the first year, I believe that there must be many people who are interested in chemistry, and then they will use some small means to make more and more people devote themselves to the study of chemistry.

When Li Yu imagined the development of the chemical industry in the future. But I heard Yuan Tiangang say again at this time: "Your Highness." Speaking of chemistry, it is not yet taught separately. However, there have been a lot of students who are particularly interested in chemistry to form a small group, this group is conducting research in chemistry alone, and there are some results, Poor Dao invited His Highness this time, one of the reasons is to ask His Highness to see if their results are valuable? ”

"Oh? How could there be such a thing? Li Su was also very surprised when he heard this, but he didn't expect that this had just started teaching, and there was already a chemistry interest group.

"Hehe, in fact, this is not surprising, didn't His Highness already let us study the abrasion resistance of the gum last time? At that time, I invited a lot of Taoist friends who were very accomplished in alchemy and medicine, and they are now all teaching in the academy, and these people are very obsessed with the chemistry foundation sent by His Royal Highness, and they often discuss their experiences with each other. Yuan Tiangang explained with a smile.

"I see!" Li Su also nodded slightly after hearing this, not only did he fund them to build the Taoist Academy, but also sorted out some of the chemical foundations he knew, and sent them all to the Taoist Academy, although these foundations are nothing at all, but it is the basis of modern chemistry in later generations, especially the substitution of chemical element symbols and molecular formulas, although Li Su can't remember all the chemical element symbols and molecular formulas, but anyway, it's just a symbol, and he can create another one, for example, oxygen was originally O, but in Datang, Li Su can write a random symbol instead of o, anyway, he just knows that it is oxygen.

While the two were talking, the carriage kept moving rapidly, and soon arrived in front of the gate of the Taoist Academy. The Taoist Academy was built directly south of Chang'an City. In fact, in order to show the difference between their Taoist academies, Yuan Tiangang also asked Li Shimin for instructions, and after the other party's consent, he actually built the Taoist Academy on the extension of the central axis of Chang'an City, that is to say, the Taoist Academy and Li Chunfeng's Chang'an Observatory are in a straight line.

However, the Taoist Academy is not so close to the observatory as far as Chang'an, after going out of the Mingde Gate, it has been going south for ten miles, before it will reach a hill that is not high, although the mountain is not high or big, but the scenery is very beautiful, so it was selected by Yuan Tiangang, the Taoist Academy was built on this hill, and in order to facilitate traffic, a very wide mountaineering ladder was also built, and there is a cement road under the mountain to connect with the cement road of Chang'an, and the traffic is also very convenient.

When Li Su arrived at the hill where the Dao Academy was located, he immediately frowned, because the Dao Academy was built on the top of the mountain, and if you want to go to the Dao Academy, you must pass through the very wide mountaineering ladder in front of you.

However, Yuan Tiangang did not pay attention to Li Su's demeanor, but pointed to the hill with some pride: "Your Highness, please see, this mountain was originally nameless, in order to build a Taoist college a year ago, we bought this nameless hill, and named it Daoshan, the mountain gate in front of it was donated by King Huo, the whole body is carved with good white marble, it can stand for thousands of years, and after passing through the mountain gate, it is the mountaineering ladder of Daoshan, with a total of 999 steps, these are donated by the believers of Chang'an!" Yuan Tiangang said excitedly.

When Li Su heard that there were more than 900 steps, he immediately rolled his eyes angrily, this mountain was not high, and they also built more than 900 steps, each step was less than ten centimeters high, which was a big waste. As for King Huo in Yuan Tiangang's mouth, Li Su also knew that it was the fourteenth brother of his father Li Shimin, named Li Yuanliang, who had a good reputation, and had a good relationship with Wei Zheng, and even married Wei Zheng's daughter as the princess.

Although the Taoist Academy is not a Taoist temple, but there are also a group of Taoist priests gathered in it, so the rules of the Taoist temple are not bad here, such as if you want to go up the mountain, you must pass through the mountain gate, and then walk up step by step, so as to show the sincerity of the Taoist seeker, the Taoist Academy is no exception, although Li Su does not believe in Buddhism, but Taoism is the state religion established by their old Li family after all, so the necessary attitude still has to be done, so in desperation, I had to follow Yuan Tiangang step by step to climb to the top of the mountain.

After arriving at the top of the mountain, Li Su was tired and really beat his waist, compared to Li Su's embarrassed appearance, Yuan Tiangang, who was full of white hair, looked very relaxed, only a little sweat on his forehead. Li Su couldn't help but feel a little guilty when he saw this, could it be that these cultivators have a relatively long life, and it is estimated that they have all been trained by climbing mountains.

For example, after climbing to the top of the mountain, the first thing Li Su saw was the Sanqing Palace dedicated to Sanqing, and after entering the Sanqing Palace to worship Sanqing, he could only enter the real Taoist Academy.

Compared with the military academy that Li Su personally supervised the construction, the building of the Taoist Academy is even more unique, and it can even be said that this is actually a super large Taoist temple, but it is mainly used for teaching. As soon as he entered the Taoist Academy, he immediately heard a clear recitation sound coming from the high-rise building next to him, and the only thing Li Yu could hear was a Tao Te Ching, and the others didn't know what the Taoist priest in the building was reading?

"Your Highness, this is the closest to the Sanqing Palace, so it is a place to learn the Tao, and through here, you will reach the back mountain, where the buildings are completely different from here, but imitate the military academy, built rows of small buildings, where you really learn chemistry, called the School of Chemistry, and the students are usually divided into two groups to study." Yuan Tiangang listened to the recitation next to him, stroked his beard and introduced with a smile.

"Oh, I didn't expect that Yuan Daochang not only has amazing physiognomy, but also has such superb management skills, which really makes Li Su admire!" Li Su also said with a smile. This academy has just been established, and it can be planned so well-organized, which is indeed not something that ordinary people can do.

Yuan Tiangang was also quite satisfied with the Taoist Academy he founded, but he was still humble on the surface, and then led Li Su, dressed in layers of courtyards, and walked towards the School of Chemistry in the back mountain. Of course, he was not idle along the way, while walking, Yuan Tiangang introduced the various architectural functions of the Taoist College to Li Su, but because the establishment time is too short, some buildings are still under intense construction, and it is estimated that by the end of this year, all the Taoist colleges will be fully completed.

After passing through the living area in the middle, Li Su and the others finally came to the School of Chemistry, but in front of the gate of the School of Chemistry, Li Su saw an unexpected person standing there, which made him very surprised, and he couldn't understand why he was here for a while?
