Li Er's will is the will of God, so his words have always been canonized as holy decrees, that is: the will of saints.

Under his order, the construction teams sent by the entire Chang'an and Luoyang from the Ministry of Industry began to rush work day and night.

Xu Yang has never been to Luoyang, but it does not affect his understanding of Luoyang, if Chang'an is the political center of the Tang Dynasty, then Luoyang is the economic and cultural center of the Tang Dynasty.

Because from the concentration of overseas commodities in Luoyang storage, trading, unloading, transportation, etc., it can be seen that its role is no different from that of Shanghai in later generations.

The history of the Western Han Dynasty and the Eastern Han Dynasty tells us that the capital of Chang'an is to guard the border with the capital, and the capital of Luoyang is to use the capital town of the Central Plains.

Historical experience tells us that the capital of Chang'an is an offensive and expansive national policy. Dingdu Luoyang is a comfortable and wealthy strategy.

Obviously, Li Er's current soft and hard power, he will never become a master of success, his goal was to destroy the Turks, conquer the Uighurs, and make achievements for all generations, so that future generations can worship, and now his goal is to conquer the earth on the globe that Xu Yang once gave him.

Although Chang'an is prosperous, Xu Yang has also thought carefully, and finally came to a conclusion, that is, Chang'an is not suitable as a broader place for business, what is more needed here is the elegance and bearing of a great country, extraordinary system, and novel technology, these are what Chang'an needs, as for commercial prosperity, it is just the icing on the cake, the lion and the tiger to add wings.

Fundamentally speaking, system and science and technology is the soul of Chang'an, but also the foundation of Datang's life, as a modern person in the 21st century, Xu Yang knows the importance of science and technology, you don't see Lao Mei Heng as the world's police, pointing out the country, see who fights whom, in the final analysis, or because it has a strong cultural and technological strength, a missile can accurately lock on and hit the target, you are still holding millet plus rifles, not a level at all, how to fight this battle?

To be honest, after Xu Yang catalyzed Nanshan Academy many times in a row, the gentlemen and R&D personnel of the academy have no innovative concept anymore, and they are looking forward to new drawings and materials for their own research all day long. Unsound technology will make R&D personnel and scientific and technological workers lose their enthusiasm and inspiration for R&D.

Therefore, since the drawings of the steam train, Xu Yang has never printed any industrial drawings, and informed the R&D department of the academy that from now on, no drawings will be distributed in the research and development of a qiē research and development, and the improvement process is all based on independent research and development.

As soon as this news came out, the craftsmen of the R&D Department of the academy were surprised, and there were also surprises, just like a person walking on a road, originally the whole road was full of lights, and it was clear where to go, but now, all the lights on the road were removed and replaced with a torch in their hands, this gap was difficult to accept for a while.

In the first week, the academy was full of mistakes, endless ideas were mixed, all kinds of plans and designs appeared in one go, and at the weekly general meeting, Xu Yang was shocked to hear many interesting ideas, how similar these ideas were to the mistakes in human history.

Among them, there is a person in the academy who is very interesting, and Xu Yang is impressed by this person, this person's name is Xu Zhiqian, and Xu Yang has the same surname, five hundred years ago, it was a family, and it is also a Youzhou people's family, when he was a chemical gunpowder real yàn room personnel moved to Chang'an to settle down, he used to be a Taoist priest, alchemy had several explosion accidents, and he felt that this thing was related to Changsheng, and since then he has studied carefully, but after studying for more than half a year, there was no result, and he was about to give up, so he was recruited by Xu Yang into the Liu family, Became an underground worker: research and development of safe gunpowder.

Since then, Xu Zhiqian has known that the explosion in this world was actually caused by the ignition caused by the mixing of sulfur, charcoal, and saltpeter, and the power of the explosion will change differently as the mixing ratio changes.

This research result made him ecstatic, and since then he has stayed in the real yàn room all day long, studying these miraculous phenomena, and the enhanced version of the powerful gunpowder used in Youzhou to blow up the mountain was researched by him, and Xu Yang also rewarded him with fifty taels of silver.

However, since a few days ago, the technology of gunpowder has become mature, and the existing gunpowder is both convenient and cheap, so Xu Yang terminated the research plan of gunpowder, leaving only a person in the real room to develop military explosives.

Xu Zhiqian was arranged to the aircraft room, when he first came to work in this room, Xu Zhiqian was 10,000 unhappy, his beloved was gunpowder, and he didn't have the slightest affection for the department that didn't know what the name meant, and asked to be transferred many times, but Xu Yang didn't allow it, and still let him study the aircraft here.

Xu Zhiqian didn't know what to do in order to do what Xu Yang described, 'let people fly to the sky'.

Just relying on his hobbies and fantasies, Xu Zhiqian had no choice but to come up with his own plan at today's Guangkai Speech Conference, that is, to tie a lot of gunpowder to a seat, use the thrust of gunpowder to fly into the sky, and then unfurl a kite and go down with the wind.

Unexpectedly, at the conference, Xu Yang heard his own construction, and was actually stunned there for a long time, what Xu Zhiqian didn't know was that in the original history, hundreds of years later, in the Ming Dynasty, there was a person named Wanhu who had the same idea as him

"The idea of the aircraft room is very good." Xu Yang was stunned for a while before nodding with a smile and said: "But this idea is still a little wrong, first of all, the stability of gunpowder cannot be controlled, what if there is an explosion?" Then came the landing after the heavens, have you ever tried how big a kite you have to use to carry the weight of a person? ”

The construction of the railway track in Luoyang officially began, and the ironworks of the eldest grandson's family now supply all iron products to the railway, but even so, the steel required for the erection of the railroad is still insufficient.

Li Er ordered people to seize the time to mobilize steel from major iron mines across the country, smelt all of them, and make railroad rails.

The main reason is that a major event has happened in the R&D department of the mountain behind Nanshan Academy: researchers from the aviation department have to test how big a kite can fly a person R1152
