Arrived at Tiandu Mansion in less than an hour, Tao Ziyuan and Chen Yan can be said to have returned with a full load, and when they got off the boat, Tao Ziyuan knew that the boat was not rented by Chen Yan, but bought by him. The boatmen on the ship are also from the Zhuangzi.

It was already early afternoon when he arrived at the ferry port of Tiandu Mansion, and Tao Ziyuan didn't expect that he would also meet foreign envoys and Li Xiangqing here after strolling around the mountain villa after eating.

Not at the ferry port of Tiandu Province, but at the gate of the armory factory not far from the villa.

Since they met it, it was inevitable to go over and say hello, and Chen Yan was also very interested in what they were studying.

Walking over, the two sides greeted each other, and they just asked each other something about why the other party was here, and then the two were invited into the armory factory together, as if the envoy wanted to introduce something to Li Xiangqing.

Tao Ziyuan listened to the side, as if the envoy had talked to the emperor about building a ship with iron, and took out a set of drawings, and the emperor asked Li Xiangqing to follow him to Tiandu Mansion to try it.

As for why it is not in Yandu, naturally there are important things that cannot be seen by the envoys.

"A ship made of iron? It's too unbelievable, won't it sink when it reaches the water?" Chen Yan asked, and Tao Ziyuan on the side also looked over, and Li Xiangqing also had the same question.

After all, a sword that falls into the river will not float on the surface of the river, let alone a ship made of iron to make such a behemoth.

But since His Majesty asked the envoy to give it a try, that is, he also has some interests, and it is good to succeed, but it does not hurt if it is not successful.

————

The envoy's surname was Li, and his name was very long, and the emperor couldn't remember it, so he gave him a Chinese name called Li Ao, and the envoy himself was very satisfied.

As for the beauty in the palace, she was named a lady one night later, living in Jingyang Palace, and she was also given the name given by the emperor, surnamed Bai and named Yurao.

However, this name, Tao Ziyuan, felt that it couldn't match that lady.

Having said that, Li Ao is not from Li Qing, his speech and demeanor are decent, but he is not the same concept as the elegance advocated by Li Qing, it can be seen from his words that this person is an open learning mentality for all things in Li Qing, but he is neither humble nor arrogant.

He likes to embrace these new things for him, but not all.

He didn't deal with Chen Yan and Li Xiangqing very easily, and it can be said that his thinking was different from Li Qingguo's people.

Later, Tao Zikite came into contact with a word, called aristocracy.

Li Ao is a noble son, equivalent to Li Qing's imperial relatives, but in their country, men will not take concubines, and exchanges will not be secretive, and they have made a detour.

So Li and Chen didn't mean to embarrass him, but nothing embarrassing happened.

But the things that the two of them want to explore have been almost explored, and the rest is what Li Ao himself doesn't want to say and won't say.

Shallow and hidden, it was practiced by two people very well, which Tao Ziyuan was ashamed of.

However, people are self-aware, Tao Zi Kite promotes his strengths and avoids his weaknesses, and focuses on listening.

Finally saw the official of the armory factory, and the official found a few blacksmiths and allocated them to Li Ao, Li Ao finally opened the drawings after seeing the blacksmith, Tao Ziyuan was fortunate to have a look, but she looked at the things on it a little dizzy.

The dimensions are different from Li Qing's, and she doesn't understand the things called "numbers" very well, but in general, she can still feel that the accuracy of this drawing is much more accurate than Li Qing's drawing.

"If you only need a model, you can double the size of this drawing, and I need you to make a ruler for the numbers on it, as a standard. ”

Li Ao talked to the blacksmith next to him about the things that needed to be paid attention to on the drawings, and Tao Ziyuan looked at it and felt very strange and interesting.

"That'...... How long does it take to build a ship? As you said, buoyancy is related to density. But how do you measure the density, how do you calculate the buoyancy, how do you know if the ship will not sink?"

Tao Ziyuan raised her doubts, of course, looking at the expressions of Li Xiangqing and Chen Yan, she knew that what she asked was also curious about the two of them, after all, the two of them were going back to deal with each other, and it was easy to explain these things if they understood it.

As for ignorance, leave it to yourself.

Li Ao looked at Tao Ziyuan with surprise in his eyes, as if he had seen a person who finally knew the goods, the feeling that Maxima had met Bole,

"This ...... It requires very complex calculations, and if you want to understand, Madame, I can lend you a book with some of the most basic knowledge. ”

Tao Ziyuan blinked and glanced at Chen Yan next to him, who smiled, as if to say, what do you want to ask, just ask.

"But can I understand your words?"

Tao Ziyuan asked.

The biggest problem is the lack of literacy, for example, she doesn't understand this number, let alone their own language.

Looking at the eyes of Chen Yan and Li Xiangqing together, Li Ao smiled and said,

"Madame, please rest assured, I will translate the book into the language of your country, if Madame does not understand anything, you can ask at any time, Madame Bai in the palace is also quite insightful. ”

"In that case, thank you very much, Master Li. Tao Ziyuan smiled and saluted, and then stayed quietly and watched Li Ao instruct the blacksmith to use the standard ruler.

Chen Yan and Li Xiangqing were also watching from the side, the specifications of the ruler are not very complicated, but they can't come out today, but what matters is the information revealed by Li Ao's words and deeds.

"Captain Chen, do you see it? This is not a simple character. Li Xiangqing and Chen Yan whispered on the side, and Tao Ziyuan was fortunate to hear a little bit.

Chen Yan didn't move, but he answered,

"Well, it doesn't leak, it looks cool, but it's thoughtful. Our set didn't work for him. ”

Li Xiangqing curled the corners of his lips and said, "Yes, Your Majesty also wants you and me to see what kind of background this person is." What is the purpose of their coming to Liqing? ”

"Your Majesty?" Chen Yan was puzzled, and Tao Ziyuan didn't understand either, but he understood in an instant, the emperor knew that the two of them would come to Tiandu Mansion today, so he asked Li Xiangqing to bring his envoys here.

After figuring out this joint, Chen Yan continued,

"What are you going to do?"

Li Xiangqing smiled, "Naturally, we just wait and see." His Majesty meant that what he was making was really interesting, and it didn't hurt for him to give it a try. ”

Chen Yan glanced at Li Xiangqing next to him and didn't say anything, but Tao Ziyuan understood that an invisible tacit understanding had been reached between the two people.

Tao Ziyuan felt that things seemed to have become interesting, because of the intervention of this foreign envoy, Chen Yan and Li Xiangqing actually joined forces invisibly.

The sound of striking iron continued, sparks flew in the furnace, and the molten iron that popped out of the furnace splashed on the ground and made a sizzling sound.

Behind the sparkle was the focused appearance of a tall, exotic man.
