"Dear Emperor of the Tang Dynasty, on behalf of the Gaoshan clan, Tubo, came to visit the country of the Tang Dynasty, it is an honor to meet you in person." Mo Dada, speaking stiff Chinese, stood in the magnificent Liangyi Hall and said to Li Er, who was sitting on the golden throne.

Li Er looked at these strange people with red mud on his face curiously, and a kind smile appeared on the corner of his mouth.

"Excuse me, I heard Guigu Xu Yang say a long time ago that there are people on the high mountain, and the face is red mud. Wearing a coat, taking the sky as the quilt and the earth as the seat, the people of the Central Plains will go to your high mountain land, it will be more and more difficult to walk, and it is very easy to get tired, I heard it at the beginning, I checked the classics, and I couldn't find out when this Tubo appeared, these years, there are no Tubo people to visit the Central Plains, and now, I finally see it, I am very pleased. ”

Li Er said a lot of words, but it is estimated that Mo Da half understood, but he saw that he was embarrassed and didn't know how to reply.

"Your Majesty doesn't know, I'm a Tibetan person, and I have had mutual visits with the Central Plains people for a long time, not as Your Majesty said, there is no intersection." I saw a man in a Tibetan costume standing behind Mo Dada, speaking fluent Chinese, striding forward from behind Mo Da and performing a standard Han salute.

Li Er was very interested in this young man who took the initiative to come forward, and Li Er had always had a good impression of a person who could speak Chinese so proficiently.

"Oh? Who are you? Li Er stopped both sides from trying to go up and capture this boy who didn't know the height of the sky, and asked him with a smile.

"His Majesty Lu Dongzan is a minister who sent an envoy to the Tang State this time, that is, the position of the Zhongshu Shilang of the Tang Rite Department." Lu Dongzan faced the vast and coercive hall, without the slightest fear, and still looked confident.

Li Er looked at Lu Dongzan again in surprise and asked, "Since you said that you have had a lot of contacts with the Tang people, why have I never heard of you, and I haven't seen you in ancient books?" ”

"Qi Yu Majesty, the Tang people we met are all Tang people in the mountains and wilderness on the border of our Tang Dynasty, they all seem to be from the same place, oh, by the way, they call themselves Mojia"

"Tut-tut, the old man has been studying the technique of the mechanism for many years, but I didn't expect weights and measures to be so subtle, it's really ashamed."

An old man in a gray robe, in an ordinary workshop, saw that each of the technicians was holding the same scale, so he wanted to come over to take a look, and soon knew how to use this thing, and then sighed.

Xu Yang is a little embarrassed, every time these things are taken out in the future, they will make these ancients make a fuss, no way, who let them have the constraints of their own times, and it is normal for their thinking to not keep up, so Xu Yang will not criticize them for being short-sighted or something.

The mechanic on the side rolled his eyes and looked at the gray-robed old man, and said in a disdainful tone: "These are the most basic tools in the factory, have you ever seen a vernier caliper?" Have you ever seen a protractor? I haven't seen any of these, and I'm embarrassed to say that I have been researching for many years? Then he nodded and said to Xu Yang: "Lord Jun, the factory is now making improvements to the locomotive, according to your instructions, this time the 2.0 version of the train has corrected many errors and deficiencies of the previous generation, and it is estimated that the new generation of locomotives will be able to make zuò at the beginning of the year." ”

Xu Yang didn't notice the embarrassment of the gray-robed old man, and said solemnly: "Erhuzi, don't think that you know a lot, if you learn a little bit of the art of the ghost valley, you will become unpopular, this Mr. Chen has been immersed in the Yin organ for a long time, and it is estimated that he is older than your father's age, and he is a guest from afar, so he must not be rude." ”

When he said this, the young man named Erhuzi suddenly made a 180-degree turn in his attitude towards the gray-robed old gentleman, and complimented: "Oh, look at my mouth, it's really underwhelming, I thought you were a newly hired quality inspector from the factory, but I didn't expect it to be a friend of the county lord, it's really rude, Xiaosheng is so offended, and please ask the old gentleman Haihan." ”

Chen Tianyun was a little inexplicable, he was very curious about what kind of identity the quality inspector was, and at the same time felt an inexplicable expectation for his next life, nodded and said that he didn't care, Chen Yuntian followed Xu Yang to continue browsing the core secret area of the Tang Empire.

Dozens of staggered caves, hundreds of working rooms, each time he passed by, Xu Yang patiently explained, whether it was the old man in the gray robe or Guiguzi, they all appreciated the style of teaching Datang science and technology, it can be said that Xu Yang's move not only showed Datang's strong research and development capabilities, but also showed his strength to the Mo family.

As the saying goes, 'The reason why they become friends is because they have an equal status.' ”

The Mo family, as an organization that has lasted for thousands of years, although it has now fallen into decay, but the emaciated camel is bigger than the horse, listening to Chen Tianyun slightly revealed, the Mo family today still has more than 500 dead soldiers, 3,000 inner disciples, and more than 30,000 outer disciples, most of which are out to practice, living in the world, once the organization is called, they will rush immediately.

In the face of such a large organization, Xu Yang was very nervous at first, but later, after hearing about their intentions, Xu Yang felt that life was really 'the mountains and rivers are exhausted, and there is no way out, and the willows and flowers are bright and another village'.

It turned out that these people had come to find the long-lost method of making zuò from the 'Suzaku Mechanism'.

Legend has it that the ancestor of the Mo family, Mo Zhai, is a generation of organ masters, he created the art of the machine, started more than thousands of ways to card together, only did a lot of organs that benefit the country and the people, and later the public lost to help the Chu State attack the Song State, Mo Zhai only relied on his own strength, using more than 30 ways to defend the city, the public loss class was turned away, and finally persuaded the King of Chu to keep the Song State.

Later, Mo Zhai returned to the Song Kingdom, and felt that the Chu State had rebelled, so he escaped into the mountains, painstakingly studied, and finally created four supreme organs, named Qinglong, White Tiger, Vermilion Bird, and Xuanwu Four Organs, but because the four organs were too murderous, and contrary to the Mo family's always upheld love and non-attack, therefore, the first generation of giants Mo Zhai sent a message that these four organs must not be activated until the moment of life and death.

In the past, when Xu Yang read the description in the history books, he felt that it was really powerful, what supreme mechanism, in a powerful organ can be as powerful as the musket of later generations? Can it be worth 100,000 iron horses? I'm afraid these are just YY of the ancients.

But when Chen Tianyun sent the white tiger mechanism to Xujiazhuang, Xu Yang realized that he really underestimated the wisdom of the ancients.

That white tiger mechanism, said to be a white tiger, but in fact is twelve huge repeating crossbows, in different directions, the crossbows are engraved with tiger head signs, a crossbow arrow has half a catty and more than 30 centimeters, Xu Yang has no doubt that this thing is going to be set up from the city tower, how much the soldiers besieging the city need to pay, and a crossbow arrow is more than enough to skewer four or five people.

How ruthless does this old guy Mo Zhai have to be, and can he still be killed if he is shot by something? Erecting this thing on a city tower is even more deterrent than setting up a machine gun, after all, just by seeing this huge crossbow arrow, you can imagine the terrifying scene of being shot through, and the most terrifying thing is that this thing is not just one, but twelve, and the deterrent level can be increased by dozens of percentage points at once.

After sending the white tiger over, the nineteenth generation of the Mo family had a secret meeting with Xu Yang, and the meeting was nothing more than about the Vermilion Bird Organ, in the final analysis, it was caused by Xu Yangdang's nonsense after the success of the first flight in the academy.

The academy's flyer test jump was successful, and it was widely published in the newspaper, and the original words of Xu Yang, the focus of the news, were naturally written in the "Datang News":

"Our Guigu has already had a flying mechanism, I heard that the Mo family in history invented the Vermilion Bird Mechanism very early, and the things in our Guigu are more advanced than it, but now is not the time to take it out, compared to directly using the flying machine of Guigu, this county lord hopes that Nanshan Academy can independently develop the world's first aircraft "R1152".
