Ma Daochang's residence was renovated by Yang Bo, and the partition walls of the front and rear rooms were torn down and replaced by a transparent mahogany multi-treasure grid, which received guests in front and was more spacious, and in the back was Yang Bo's office.

When Su Luoer came in, Leshui was practicing calligraphy inside, Pingsu Yang Bo was not there, Leshui taught Yiming to recognize words, and Yiming taught Leshui arithmetic, the two helped each other learn from each other, and the effect was not bad.

Yang Bo's sign language is also a common dozen, Yiming has basically learned it, Leshui has seen a lot, and it will be a little, and the two of them can do some simple communication, and it is not a big deal.

"Sister Luo'er." When Le Shui saw that it was Su Luoer, he immediately dropped his pen and greeted him, and the two looked very affectionate.

When Su Luoer saw Leshui, compared with the outside just now, she was completely like two people, and her gestures were gentle and quiet, just like everyone's girlfriends.

Su Luoer sat down on the embroidery collapse, took Leshui's small waist lightly, touched Leshui's little head dotingly, asked for warmth, spoke, and put her hands on Leshui's double bun.

Yang Bo smiled: "It's good-looking, but Leshui's outfit doesn't match this." ”

Su Luoer gave Yang Bo a roll of her eyes, and said coquettishly: "You are also big-hearted, Leshui is such a little beauty in the stone temple, and I don't know how to take care of it, when we worshiped the moon god yesterday, we said that today I will take Leshui to buy some suitable dresses." ”

Yang Bo also felt that Leshui had grown taller recently, and there was a little bit of a bulge on his chest, Leshui at this age was like a flower bone on a plum branch, and the double bun was very suitable for her.

Le Shui combed his hair in a bun, a little excited, a little nervous and shy, at a loss for a while, his eyes looked at the door, but he saw Xiang'er and Shen Yiming coming back, and the black dots shook their heads and tails and followed behind.

Leshui hurriedly jumped up, caught up, grabbed Xiang'er's hand, and said happily: "Xiang'er, I worshipped the moon god last night, you worship..."

Xiang'er didn't finish speaking, so she made a silent action, and when she saw that Su Luo'er was also there, she gave a perfunctory blessing, her face was lukewarm, and she pulled Leshui and walked out, along the way, the two of them muttered quietly.

Unmarried women worship the moon god, most of them ask for marriage, hoping to give Xu a good family in the future and marry a wishful husband, how can this kind of thing be talked about in front of everyone? Xiang'er strictly abides by the rules, of course, she can't let Leshui make mistakes.

Yang Bo and Shen Yiming communicated in sign language, and after gesturing for a while, Shen Yiming also nodded happily and left.

Su Luo'er couldn't help but ask curiously: "Young Master Yang, what did you say to Yiming, he was so happy?" ”

"I asked him to practice calligraphy, and when I was done, I played with glass beads with him, which was a little game." Yang Bo said with a smile.

Su Luoer said in her heart, you also play the game of playing glass beads? Yang Bo, she really can't understand it.

The fact is not as Su Luoer thought, Yang Bo is using games to improve Shen Yiming's ability to communicate with people, playing glass beads requires complex geometric knowledge, although the game is simple, but rich in connotation.

Su Luoer's trip was to ask for a brief score, especially after Yang Bo sang a song "When is the Bright Moon" last night, which aroused endless curiosity in her heart, but her curiosity was not only in music theory, but Yang Bo was even more interested in her.

The simple score uses Arabic numerals instead of musical notes, Yang Bo first wrote down 1234567 line of number symbols, but he didn't expect Su Luoer to recognize Arabic numerals, and after talking, he knew that Su Luoer knew Xu Erjue, the grandson of Xu Guangqi, which was no wonder.

Yang Bo knew that Arabic numerals were introduced to China very early, but their popularization was very late, mainly because China has the artifact of abacus, which is already very convenient and is not needed.

In terms of music theory, Zhu Zaiyu, the down-and-out prince of the Ming Dynasty, is the first person to use mathematical methods to obtain twelve equal law data, nearly a hundred years ahead of the West, the music theory of ancient notation and simple notation is the same, Yang Bo explained the notation methods and rules of the simple notation, Su Luoer also understood in seconds, but Yang Bo spent a lot of effort to understand the notation of the ancient notation.

Su Luoer used a simple score to record "When Will the Bright Moon Exist".

The two of them were babbling and singing with a simple score, and Shen Yiming, who was practicing calligraphy on the side, felt interesting, and poked his head over from time to time to glance at it.

Su Luo'er got up and wanted to take a pen and paper to record what she had gained today, and before sitting down, she also gave Yang Bofu a playful salute and said softly: "Nu'er has benefited a lot today, thank you for your advice." ”

Yang Bo said modestly: "Then Sister Su will come to the stone temple more often, we have in-depth exchanges, and both sides will benefit, hehe." ”

When Su Luo'er heard this, she thought about it for a while, her pretty face turned red, she bit her lips, leaned over, and whispered, "How deep does Childe want to go?" ”

A deep ditch came into Yang Bo's eyes, pink, white, fragrant, and fragrant, making people reverie.

Yang Bo suddenly looked embarrassed, picked up a pile of Shen Yiming's words, and flipped through them casually, wanting to cover them up.

"Huh.." Yang Bo saw a piece of paper full of numbers, and carefully identified it, it seemed to be the score of that song, could it be that Shen Yiming also learned the simple score? I couldn't help but ask in surprise, "Yiming, have you learned the simple notation?" ”

At this time, Su Luo'er had already sat down upright, quiet as a virgin, and when she heard Yang Bo ask, she couldn't help but look over.

Shen Yiming shook his head and gestured with his hand, Yang Bo then understood, Shen Yiming just remembered the correspondence between the notes and the numbers, just now Yang Bo and Su Luoer tried to sing with a simple score, Shen Yiming wrote it down on a whim.

This at least shows that Shen Yiming is very sensitive to symbols.

Shen Yiming used to learn arithmetic and used words, Yang Bo immediately used number symbols to come up with a few questions, and Shen Yiming could quickly make them.

Yang Bo wrote a series of alphabet symbols, and Yiming will soon be able to write, like a sponge absorbing water, and the speed is so fast that people smack their tongue.

Yang Bo remembered that there was an incomplete periodic table in Ma Daochang's laboratory secrets, and he thought that in the future, Yiming could learn to identify chemical substances, and Ma Daochang recorded them with chemical symbols, and learning to recognize letter symbols meant that he could understand Ma Daochang's secrets.

Xu Wenjue Shanshan was late, and when she came, Su Luoer took Leshui Street to buy dresses.

Yang Bo got the report and hurried out of the temple gate to greet him.

Xu Wenjue was accompanied by Qin Shao, holding a small gold-painted fan in his hand, fanning it with a whirring voice, sweating profusely, as soon as he saw Yang Bo, he complained, "Yang Bo, why do you live in such a place?" My feet are about to break. ”

Qin Shao echoed with a smile: "The road over Erdaogou is really difficult to walk, there are no sedan chairs and no horses here, and it is bitter." ”

This little grandfather Xu is a sensual dog and horse owner, at a young age, he has a bunch of fat meat, usually either riding a horse or sitting in a sedan chair, coming from Shenjiabao is indeed a challenge.

"Wenjue, the road is being built over there, this road is being repaired to the east to the gate of the Shen Mansion, and to the west through the gap in the West Mountain, to Meizhen." Yang Bo pointed to the gap in Xishan and said with a smile: "I have a horse farm in Meizhen, Brother Wenjue will definitely let you have a horse to ride next time, haha." ”

Fat Dun'er looked around and said, "It's time to build a road, it's too remote here." ”

"This road runs through the swamp in front, and the swamp will become a treasure of feng shui, and if you invest in silver now, you may benefit several times in the future." Yang Bo said seemingly casually.

Xu Wenjue stretched his neck and looked, the swamp was full of withered reeds, and he couldn't see the end at a glance, so he threw silver into it?

"Tell me, how much silver shall I give you?" Xu Wenjue said tentatively, his tone a little dark.

"Not for me, I don't want your silver." Yang Bo said seriously, "South of this road, there are about 7,000 acres, you need to pull sand and gravel from the West Mountain to fill it, and it will be yours to fill it up, and you can build a house on it in the future, residences and shops, I have a request, that is, to plan it in advance, otherwise it will be chaotic." ”

"Childe, as far as I know, there are only so many people in Shenjiabao, who will live in the house after building a house?" Qin Shao asked.

"Brother Qin, investing in silver and shares, but paying attention to being one step ahead, I don't say much, I have proved with my actions that there are still 2,000 acres on the north side of the road, all of which belong to me, and I have begun to let people fill in." Yang Bo said lightly.

Xu Wenjue looked at Yang Bo, his eyes were like looking at a fool, Yang Bo knew that this kind of thing was not in a hurry, and he didn't force it.

The three of them came to the office room, and Yang Bo asked people to bring a model and put it on the ground, looking heavy.

"What is this?" Xu Wenjue and Qin Shao asked in unison.

"It's a model of a bridge, it's made with something called cement poured into a mold, and you can touch it, feel it, it's like a stone."

Yang Bo made dozens of catties of cement in the laboratory, all of which were used to make this model.

Yang Bo personally surveyed that to open up the road in Xishan, it was necessary to cross several small river ditches along the way, and several bridges needed to be built, otherwise it would be necessary to detour a long way, and the cost would be too high to bear.

Xu Wenjue said in his heart, Yang Bo wouldn't be carving a bridge out of stone to fool him, right?

In a moment's interest, he walked around the model, knocking east and west, to make sure that the model was not made of stone.

"Little grandfather, it's better to smash it with a hammer and you'll know it when you try." Qin Shao came up with an idea on the side.

Yang Bo asked people to find a hammer, Xu Wenjue really smashed it, where the hammer fell, sparks burst out, but there was only a white trace left on the bridge, which was really as hard as a stone.

Xu Wenjue was shocked, he was sure that it was not carved in stone, so this bridge was really made of cement, so cement is like a match, it is indeed a new creation that has never been seen before?

Xu Wenjue's eyes were shining, and he said urgently: "Yang Bo, how much silver do you have to invest to make this cement?" ”

"Five hundred thousand taels." Yang Bo said in a deep voice.

Qin Shao and Xu Wenjue were both shocked, Xu Wenjue looked at Yang Bo with wide eyes, Yang Bo looked very serious, not like he was joking at all.

This is really beyond Xu Wenjue's expectations, he originally only wanted to use his private money to invest in the match factory, at best, it was only 120,000 yuan, with the meaning of playing tickets, Yang Bo's mouth is 500,000 taels, one into 50,000 taels, and he doesn't have so much silver.

Xu Wenjue was a little frustrated, shook his head and said, "I don't have that much silver, I have it at home, but I can't be the master." ”

"It doesn't matter, there are many rich people in the Ming Dynasty, in this way, you can build a bridge, I will give 400,000 taels of 200,000 taels, if Wenjue can help me bring 200,000 taels of silver, I will give you a cent, worth 50,000 taels, how about it?" Yang Bo said with a smile.
