My Daming New Empire

Yuan Qiguan laughed and said, "That's what you can't ask for. As long as Deputy Ma is in charge, we will do as we please."

Fan Qiguan also said with a smile: "As long as we don't think we are bad customers."

"Don't dare, don't dare."

After finding a carriage, he returned to Jiashan Street inside Anximen in a short while. Ma Zhicai took a special look at his own shop, but found that the door was closed. He felt a chill in his heart, not knowing what happened at home.

Urging the groom to stop the carriage, Ma Zhicai didn't care to be polite with the two guards, and ran towards the house in the alley.

The gate of the courtyard at home was open, but there was a burst of crying from inside.Ma San, the gatekeeper, was 60 years old this year. When he saw Ma Zhicai, he exclaimed in surprise, "Master, you... are back...."

Before he finished speaking, Ma Zhicai rushed in with the silver in his arms, only to hear Ma San yelling at the back: "The master is back! Heaven has eyes!"

Before Ma Zhicai ran from the front yard to the backyard, a group of nephews greeted him, followed by a large group of female family members. Seeing that the person in front of him was indeed Ma Zhicai, everyone was stunned, and then knelt down one by one. Going down, those who called father called father, those who called uncle called uncle, and laughed with tears.

Ma Zhicai asked in surprise: "What happened, why are you like this?"

Before the words were finished, only his wife's legs softened, she sat on the ground, and burst into tears.The daughters quickly went to pull her up again, and they all wept with joy.

Seeing the chaos of the scene, Ma Zhicai looked at his eldest son. "Jiner, what happened?"

Ma Jin's eyes were still red, but at this moment his face showed joy. "Not long ago, the inner supervisor sent over the money we used to be filial to, but they didn't give us an explanation. We thought something bad happened to our father..."

Ma Zhicai's heart was sour, and he almost cried.In the past ten months, from the first time he saw the globe, he thought he would not survive.

People actually live on a big sphere, and Ming Dynasty doesn't represent the whole world, except Daming, the world is still so big.

This is definitely not news that ordinary people can know. If people know that they just live on a ball, and the ball is still spinning, I don’t know how many people will go crazy.

He didn't know how the emperor and the others knew the news, but the emperor is the son of heaven, so he must have been told by heaven.

He is an ordinary craftsman, but now he knows the news.Although there is still a glimmer of fantasy, he has already accepted his fate.

But they didn't expect the grandson to show up today and let them go home.He hasn't thought about this reversal, but since the grandson came forward, it must be the grandson who pardoned their lives.

"I'm fine. I met His Highness Grandson today, and His Highness still praised me very much. It's just that the things my father did for my grandson are relatively secret, so I can't contact you. Caier, help your mother to rest first. , These 100 taels of silver were rewarded by His Highness, put them away. Come in, make tea..."

After a while, the yard calmed down.Several younger nephews also kept staring at the two Jinyiwei who were welcomed into the room by Ma Zhicai, wondering how a family like theirs could get so close to Jinyiwei.

Ma Zhicai knew very well that although his life was not in danger now, but the emperor's decree had not come down, their matter had not yet been fully determined, so during this period of time, he could not leave Jin Yiwei's sight.

After placing the two brocade guards in the guest room, he called his nephews in, besides his three sons, Ma Dao, Ma Qian, and Ma Di from the third brother's family who came all the way from Suzhou.

Looking at this group of nephews, he felt a lot of emotion in his heart, the officialdom was unpredictable, and this time he was almost separated from yin and yang.

However, if one person's death can be exchanged for a prosperous family, it is always worth it.

I just don't know what the result will be this time, if it can really be reused by the grandson, this time it will be the end of all hardships.

He beckoned to his 15-year-old nephew Madi, who is his favorite, smart and more spiritual than his brothers.It's a pity that their family couldn't take the imperial examination, which delayed him.

"Dier, why did you come to the capital this time?"

Chapter 72 improvements

At the age of fifteen, Ma Di was still half a child. Hearing his uncle's question, his eyes turned red. "I don't know if my uncle is alive or dead, so how can my nephew study with peace of mind."

The Ma family was able to grow to such a large size and opened a shop in the capital, relying on this Ma Zhicai who became an official because of his skills.

Since he was a child, he has admired this uncle and father, and he also has the idea of ​​following in his uncle's footsteps.

All scholars, farmers, businessmen, and businessmen in the Ming Dynasty could take part in the imperial examinations. Only the families of prostitutes, you, scribes, and soldiers could not take part in the imperial examinations.

The Ma family has no restrictions on studying and becoming an official, but Suzhou used to be Zhang Shicheng's base camp, and the Ma family was forced to experience rebellion.

Although the new dynasty was established and there was no excessive investigation, the Ma family was sentenced to three generations without imperial examinations, and Ma Di's generation is only the third generation.

If you want to become an official, you still can only take the road of becoming an official by relying on technology.

Since he was a child, Ma Di was clever and good at thinking, and he was more favored by his family than his somewhat dull elder brother.

His grandfather Songjiang Yu Xiaozhi was a famous master of mathematics in the Yuan Dynasty.Because there is no male in the family, he moved directly from Songjiang to Suzhou for him, just to teach him to become a talent.

Ma Di learned "Yang Hui's Algorithm" from Yu Xiaozhi since he was a child, "Enlightenment of Computing" compiled by Zhu Shijie, a mathematician of the Yuan Dynasty, and "Euclidean Geometry" passed down from the West from Yu Xiaozhi, and showed extremely high math talent.

When he was only 11 years old, he calculated that the inner intersection of a triangle is 180° through calculation, and independently proved it with a formula.

This made Yu Xiaozhi feel very relieved, and even because of this, extreme joy turned into sorrow, and he died.

After that, Ma Zhicai returned to his hometown to pick up this nephew to the capital, and personally taught him abacus calculation and family crafts, hoping that he would become the horse of the Ma family.

Before the Spring Festival, he sent the descendants of the Ma family back to Suzhou for the New Year. After the Spring Festival, he was called into the palace. Later, he brought a letter to let him study in his hometown at ease, but he did not expect that he would come to the capital again.

After hearing Ma Di's words, Ma Zhicai couldn't help sighing, and couldn't bear to blame him. "Since you're here, you can study in peace for two days. After two days, I'll take the exam on you."

Ma Di proudly puffed up his chest and said, "My nephew is not afraid of the school exam." He suddenly remembered something, and ran out without saying a word.

"This child is not calm at all..." He was concerned about his wife who was not in good health, so he taught the other nephews a few words, and then let them break up.

At this time, Ma Di ran in again, holding a telescope in his hand and said: "Uncle, look, this is the telescope I made, can the Lord of the Ministry of Industry like it?"

Telescopes still belong to ordnance among the people, and no one is allowed to hide them privately.However, Ma Zhicai not only works for the Ministry of Industry, Ma's family is also a supplier of the Ministry of Industry, supplying lenses for telescopes.

His second brother now takes over the ancestral jade workshop, and Ma Di's father, the third, Ma Zhide, has learned crystal polishing since he was a child.

Later, he opened a colored glaze kiln to make colored glaze and supply it to the Ministry of Industry.So it is not uncommon in his home that there is no telescope in other homes.

Ma Zhicai took the telescope handed over by his nephew. It looked the same as an ordinary telescope from the outside, and he didn't take it seriously, but when he put it in front of his eyes, he could see the difference.

First of all, this telescope has a larger multiple and can see farther, and secondly, it also solves the problem of blurred vision of the telescope.

The earliest telescope in the Ming Dynasty was invented by His Royal Highness Taisun. It is said that he took a convex lens as a tribute, and when he was roasting ants in the sun, he accidentally stacked two lenses together and found that it could bring the distant scenery closer. The craftsmen of the ministry installed two convex lenses on a hollow straight tube to make the first telescope.

However, the view seen by such a telescope is upside down and the mirror image is blurred.

Later, after various experiments, including adding a convex lens and a concave lens between the two lenses, the problem of mirror inversion was finally solved.

However, such telescopes depend on the transparency of the lenses.Three-layer filtering and multi-layer filtering make most of the telescopes produced unqualified. If you want to get a telescope, you need to be carefully selected by the polisher and try one by one.

This telescope has a clear view, and the zooming factor is greater than what Ma Zhicai knew.As a technical expert, Ma Zhicai immediately forgot that his wife was still waiting for him, and went outside the house with a telescope, looking towards the Qingliangshan Pagoda in the northwest.

After a long time, he put down the binoculars and asked, "Dier, have you ever calculated multiples?"

Ma Di nodded and said: "My nephew has calculated that according to the ratio of light refraction, this telescope can reach a multiple of forty times."

Ma Zhicai gasped, his hands trembling uncontrollably.Nowadays, most of the telescopes used in the military are only six or seven times, and a few can reach eight to ten times.

In order to encourage them to build a telescope that can see farther, Taisun personally promised that if they build a telescope that is dozens of times larger, they will be rewarded heavily.Not only are there financial rewards, but they can even be directly promoted to the rank of noble.
