Su Baiyi politely rejected Yu Mutong's kindness, it was too early for him to think about having a child. In this precarious Ming Dynasty, it is unknown how long he can live under the eyes of civil officials, and it is indeed better not to have a child and stay now!

Wait, when you have the power to protect yourself and there is no danger around you, it's not too late to think about having children!

After all, he is only twenty-one years old this year, and it is still early to the legal age of marriage, so it is not too late to really want children after the age of thirty.

In a sense, Yu Mutong's inability to have children just fills his physiological needs and desire not to have children without guilt, it seems a little unkind to think so, but that's the case!

In the morning, the family had a good meal together, Chunyan also bought a whole sheep from outside, called Wu Degui and Sun San to kill the sheep together, and each family shared some meat to nourish it.

Su Baiyi saw that several people were busy slaughtering sheep and thin skins, and suddenly had an idea: "Leave the sheepskins, I am useful!" But he didn't say anything. After Sun San and Wu Desheng each brought some mutton home, Su Baiyi came out of the room obscenely, holding a knife in his hand to cut off the sheep's eye circles three times and dividing them by two.

This scene happened to be seen by Yu Mutong, and asked strangely: "Xianggong, why did you cut this thing?" ”

Su Baiyi smiled mysteriously: "This is a good thing!" Hold the two sheep's eye circles in his hand and send them to Yu Mutong's side: "Soak it in cold water for a day and a night, and then put it in rice paper to dry, it is wonderful!" ”

"Okay!" Yu Mutong put the things away, and asked with some doubts: "Xianggong, what is the purpose of this?" ”

Su Baiyi put her mouth close to her ear, and muttered for a while, causing Yu Mutong's face to blush, and she snorted at Su Baiyi, and whispered: "Xianggong will bully others, you are necrotic!" ”

"How can I bully you?" Su Baiyi said: "It's not for your sake, but when you have the ability, don't beg me to ask me!" ”

Spring is shining and the sun is quiet!

After lunch, I slept comfortably, and in the afternoon, I pulled the two girls and Yu Mutong together to sit in the courtyard playing poker, three lively beauties were on the side, Su Baiyi had a kind of Lao Tzu running to the emperor at that moment, what was he doing crookedly, with three such beauties to accompany him, he would not regret being lonely in this life.

I couldn't help but think of the green night when there was no news for half a year, and my heart swelled with melancholy, and I no longer had the heart to play cards, so I put the cards in my hand on the table and said: "You three play the landlord, I'm tired, I'm tired, go to sleep first!" He lay on the wicker chair next to him, squinting at the afternoon sun.

The three of them naturally had no interest in continuing to play cards, Yu Mutong was afraid that he would catch a cold, so he brought a quilt from the house and covered him, and this confusion was another afternoon.

Spring is sleepy!

The next morning, there was a steady stream of visitors.

There are famous families in Guide Mansion, local dignitaries, close friends, elders, and students! The etiquette in ancient times was the greatest, and even if Su Baiyi was helpless, he had to meet him one by one, laughing twice and saying a few words that were not salty, not light, and not nutritious, and everyone's friendship seemed to be deeper.

This kind of meaningless communication is not completely useless, at least I received a lot of gifts, Su Baiyi shook his head after seeing it, I am afraid that there is no place to put it at home.

It wasn't until the afternoon that Su Baiyi had time to take the students to the planned place of the academy to take a look.

After going back and forth to Beijing for nearly three months, the changes in the academy are still quite big!

First of all, with the fall of the Mu family, the land acquisition and demolition work of the entire academy has been completed perfectly, and the outer wall of the academy has not yet been completed, but Hou Fangyu and Chu Lun have fenced the outer contour of the entire Yu Courtyard, and all the trees in it have been cut down, and the entire site can be seen through at a glance, and there is no possibility that someone will come over to steal the teacher to learn.

The area of the college is very large, one kilometer long and wide, and there are 1,500 acres of land, except for a small area in the southwest where glass workshops, soap workshops, textile factories and workers' dormitories are built, the rest of the place is mostly idle and full of moon flowers.

However, there are also changes, in the middle planning area, the location that was originally turned into a school by Su Baiyi has been built four low houses to serve as temporary classrooms.

"Master, according to your idea, I planted these seasonal flowers!" Bao Erhei walked beside him to ask for credit, and Su Baiyi just nodded and smiled slightly.

More than 1,000 acres of moon flowers, it is indeed Su Baiyi let him plant, now in the spring in full bloom, the moon season has also drawn out new buds, although it is not very strong from a distance, but this tender new note is like the prototype of the industrial system he carefully cared for, began to slowly show in front of the world.

"Sir, the production of glass, soap and cloth is now regular!" The black-faced Fu Lin said: "I discussed it with Chaozong, many of our students were idle, so we built a few temporary schools, and there were many new students, and the disciples began to teach mathematics, elementary physics, chemistry, biological research, and primary medicine!" ”

Su Baiyi nodded, and praised Fu Lin and Hou Fangyu's approach.

Relying on his own teaching, he can not cultivate a few talents in his life, only in this way through the disciples themselves to study, he provides teaching materials, and then the students who have learned the knowledge serve the teacher, on behalf of the teacher, so that the science can be developed step by step, in order to truly pass on the knowledge to the hands of students all over the world.

"Well done!" Su Baiyi said: "Thanks to a few of you, but in the process of studying, if there are any questions that you don't understand, you must be diligent and askable, and the most important point is to brainstorm, discuss with your brothers and sisters, and verify through experiments." Whatever you think, you must have something! ”

"Yes, disciple understood!"

Hou Fangyu, Fu Lin, Chu Lun and others all surrendered their hands!

Continuing to walk forward, behind the school is a more low house, the shape is relatively simple, and a ditch has been dug around, the ditch is full of water, and only a suspension bridge can be passed, if it is not because it is too small, Su Baiyi suspects that this thing is a small city.

"What is this repair?"

"Back to Mr.'s words!" Fu Lin said: "The business in our courtyard is getting bigger and bigger, and there is nowhere to bloom when we earn more silver, so the students boldly majored in a silver treasury, specializing in silver and copper coins!" ”

This is indeed a problem!

Banknotes are not popular in the Ming Dynasty, and there is no way to deposit money in the bank, and it is also a trouble to have more silver!

"Huh!" Su Baiyi said with a smile: "Actually, you don't need to do it like a war, you just need to build a warehouse that no one else can enter, and thieves can't enter." "It's a big deal to use reinforced concrete to pour, and bricks can't prevent thieves:" Let's talk about this later, you did a good job, how about the ore and coal. ”

After Su Baiyi went to Beijing to persuade the emperor, he sent a message to Yuyuan to ask Fu Lin to buy coal around Guide Mansion.

"Father-in-law Cao has sent several ships of iron ore and bought some coal, but there are not many supplies." Fu Lin frowned.

Cao Huachun went to Nanjing Taiping Mansion to mine iron ore, this kind of thing to do in the name of the country, as long as there is money and the local government to cooperate, the rest of the thing is to get some labor to mine, it is very simple.

At the beginning, Cao Huachun was willing to take out 500,000 taels of silver to invest in the railway, but Su Baiyi didn't really ask for his silver, but asked him to use the 500,000 taels to open iron ore, so it is not surprising that Cao Huachun transported a batch of iron ore over.

As for coal, although the people of the Ming Dynasty also used coal, the popularity rate was very low!

Moreover, there are no open-pit coal mines in the Central Plains, and the coal used by Guide is basically transported from Ruzhou (Pingdingshan Coal Mine) in Henan, and it is really impossible to get too much for a while.

Due to the long distance and inconvenient transportation, the price of coal is very high, and when it comes to Guide, one tael of silver and five stones of coal is only slightly cheaper than grain.

In terms of tons, about one ton of coal costs four taels of silver.

This price is no longer high, but outrageously high.

"How did the coal from Ruzhou come here?"

Su Baiyi turned his head and asked Fu Lin!

Coal is a problem that must be considered, this is the most important energy source for the development of industrial society, if the price of coal remains high, then the cost of industry is not too high.

"Mule and horse carts!" Fu Lin frowned and said: "The students also went to inquire, loaded the coal and stone from Ruzhou into a cart, ten cents per car, and then mules and horses traveled from Ruzhou to Xinzheng and Kaifeng, and finally when we returned to Defu, the journey was about more than a thousand miles, and a cart of coal and stone could be sold for six or seven taels of silver." ”

That is, a large cart is almost two tons.

Su Baiyi pondered for a while: "It's only more than a hundred miles from Ruzhou to Luoyang, and then you can directly come to Guide Mansion by shipping it by a big ship from Luoyang, why not?" ”

"That won't work!" Fu Lin arched his hand and said respectfully to Su Baiyi: "Mr. doesn't know, the people who can afford coal and stone in our Guide Mansion are those big families, and they can only use a few cars every year, and the overall price of loading a big ship has been reduced, but renting a big ship costs more than a dozen taels of silver each time, and it has to be transferred once, and the coal and stone transported over can't be sold, so ......"

"Oh, I see!" Su Baiyi nodded.

To put it simply, because the demand is relatively small, it is even more difficult to row with a large boat.

But he's different, he uses a lot!

"Is Guan Jin here?" Su Baiyi looked up at the hulala students behind him.

"The students are here!" Guan Jin squeezed to the front from the crowd behind and saluted Su Baiyi.

Guan Jin was a student who was responsible for the land acquisition and demolition on the ground of the entire Yuyuan, and he had a specialty that no one else could match, that is, he could speak well, and he could also be said to be good at communicating. This kind of guy is probably not good for you to put him in the room for research, but it is definitely okay to put him outside to do practical things.

"You take a few people to Ruzhou, it's best to get in touch with the local Haoqiang, let's buy coal and stone, how much you want, let them send it to Luoyang for loading, you must press the price to one tael of silver and twenty stones."

In terms of long-term planning, it is best for the imperial court to take up the Pingdingshan coal mine, and then send people to mine it. But not in the near future, one does not have so many people, and the other does not have so much energy, so I can only adopt this way of cooperating with local heroes.
