The people from Chang'an made Zhang De concerned, in addition to the maid wearing white silk, the apprentices and grandchildren of the old man Wang Xiaotong were also very important.

Since "Wang Taishi" established his status in the rivers and lakes, many things could not be done originally, but now they can be done. For example, Wang Xuedi first compiled the "Chen's Star Map", and the three codexes of Gan, Shi, and Wu, with a total of more than 1,000 stars. And because of the use of telescopes, after several years of observation in many places, this number has doubled, and by the fifteenth year of Zhenguan, there are a total of 3,000 stars in the "New Zhenguan Star Map".

There are more than 50 of the 28 constellations alone.

In addition, because of the increase of instruments, the improvement of technical means, and the actual needs of the imperial court, until the fifteenth year of Zhenguan, there were 39 new astronomical observation points in the country, including Dunhuang.

These observations first re-establish the meridian, and then reject the claim that "the shadow of the sun is an inch, and the difference is a thousand miles".

Secondly, Wang Xue's disciples and new school members set off a discussion of "retro Tianwen".

Although the scholars who mainly discussed it were younger and most of them were concentrated in Chang'an, the progress of mathematics has made more students start to discuss the concept of "the earth is like a chicken".

However, mathematical proofs and astronomical observations cannot be intuitively understood by the general public. Therefore, the scholars of Chang'an thought of a good way.

This method is to send a ship or a fleet all the way to the east, and if one day, this fleet returns to the home country from the west, doesn't it prove that "the earth is like a chicken"?

Then the question arises: which one is stronger in boat management technology!

"mentally retarded ......"

Lao Zhang was holding an impression globe in his hand, which was a prop when teaching his children, but on the side, a group of scholars from Chang'an didn't even look at it.

In short, I didn't want to prove it sooner, and I didn't want to prove it later, but I heard that a certain country in Fuso had discovered a large gold mine that was easy to mine, and I immediately wanted to prove it.

And he also went to Wuhan and asked Jianghan Observation Envoy Zhang: For the sake of academics, even a few boats come out, Zhang Observation you have no opinion, right?

If it weren't for his dirty thoughts, he would have almost been deceived by these Chang'an people.

Back then, I also found Mr. Wang Xiaotong in order to put on a vest, and now I think about it, what kind of beans are really planted and what melons are produced.

Dealing with these intellectuals, it is better to go back and play with the white silk maid, at least it will bring happiness.

"Ah Lang, what's wrong again?"

"Broken in love."

Lao Zhang rolled his eyes, not bothering to pay attention to the white silk maid.

"By the way, Ah Lang, was Ah Lang also smashed by Sister Wu with walnuts?"

"What do you ask about?"

"You were smashed by Hu Tao yesterday and blurted out?"

The maid with the bun face looks a lot rounder now, and her slender figure is stronger than that of a certain Turkic princess, if it weren't for squatting on the ground and grabbing pistachios with Zhang Wei, Lao Zhang would probably be more happy.

"Well...... It's a long story. ”

Zhang De hugged his hands, and the reclining chair seemed to be paralyzed, and he said with some lack of interest: "Back then, I decided on a family affair, and after I told her, I was smashed. ”

"Sister Wu's life is much better now, when she was still in Lizhou in the old year, if it weren't for Ah Lang, she would really have to suffer a lot. Her two brothers, I don't know if they were played to death by Sister Wu......"

"Hey! You little lady, don't talk about playing dead at every turn! ”

"Alang, you taught me."

The bun's face flickered with a pair of big eyes, as if it was very strange.

"Yes, my bad."

The whole person spread back, and Lao Zhang really felt that he was wrong.

Not only was I smashed by Hu Tao, but Lao Tzu was also stupid by Hu Tao.

Speaking of which, Wushun is still the gentle......

Lao Zhang couldn't help but think in his heart, compared with the spirit of Wu Erniang, compared with the "simple" mind of the bun face, it is still better than the Wu lady.

"Ah Lang is thinking about Sister Wu?"

You're a roundworm of Lao Tzu!

He glared at the bun-faced maid sharply, but saw her cover her mouth and sneer.

"Anu, you're bad at learning in Chang'an."

"Really? I often play with Princess Changle. I have painted more than 200 bottles in the Dongguan kiln, and when it comes to painting, Ah Lang is not as good as me. How can I say that I have learned badly? ”

“……”

Originally, Lao Zhang wanted to refute it, but it was a very shallow behavior to think about competing with a maid. As the saying goes, we must use our own strengths and attack the weaknesses of others to win all battles.

Bai Jie, who was embroidering a tiger on the side, saw Zhang De and Anu arguing, and also snickered gently, and now she is also a matter of heart. The Bai clan is now known as the "Imperial Merchant", of course, it is actually a pirate's business, but if there is no support from Zhang De, it cannot be valued by Emperor Li.

At this time, even if the Bai family is separated from Zhang De's help, with the blessing of Li Dong's halo, and following Li Simo's example of being a mad dog biting people, they can still prosper.

As long as Datang Empire Co., Ltd. does not go bankrupt, it is certain that the days will be prosperous.

As for Bai Sanniang herself, she can probably say goodbye to the Bai family in Luoyang, and then honestly follow Zhang De and "teach her husband and son" in Wuhan. Although a husband is not a husband, and a son may not be a son, for Bai Jie, the days in Wuhan are about the fastest in her life.

Out of Luoyang, out of the Bai family, from the inside out, even the soul, is extremely happy and full of freedom. Even if he occasionally has some petty temperament, Zhang De never pays attention to it, and he will not treat his sister-in-law like his father and brother, like an emperor dealing with his courtiers.

She can even let people open a silk scarf shop in Hanyang or Jiangxia, and Zhang De will not scold her with "businessman Jia cheap business" or "violating women's morals".

This kind of experience is not that outsiders think she looks like a "little woman", sitting on the side twisting needles and threading flowers silently, as if she is a puppet.

"It's just that Anu is here, so that Ah Lang is so relaxed."

Bai Jie lowered her head, still embroidering a tiger, but as soon as the words came out, it made Anu, who was eating pistachios with Zhang Wei, blush.

Suddenly, she stood up, her face flushed, and then she covered her bun face and left the room as if she were running away. Zhang Wei, who was snatching pistachios, was stunned for a while, and then cried out with a wow.

So Anu, who rushed out, rushed back again, hugged Zhang Chu, and fled while coaxing......

“……”

Lao Zhang was speechless for a while, and he didn't know what to say, and after a while, he said, "I never thought that it would be the same as before, and it was still like this." ”

"Ah Lang really spoils her."

Bai San Niangzi smiled calmly, obviously seeing through the subtlety between Lao Zhang and the white silk maid.

"Ahem."

Zhang De covered up embarrassedly, and couldn't help but recall the first encounter, "It's all the same...... There are as many heroes as dogs. ”
