Thirty-two-year-old Tang Dong was walking home, humming the tune of "The Romance of the West Chamber".
Tang Dong is now a new employee in the glass workshop, earning three taels a month.
He originally worked in the soap workshop and was recruited into the soap workshop when the soap workshop was expanding in December of the year before last. Unexpectedly, after working for more than a year, the manager Li Yousheng said that he was honest and recommended him to work in the glass workshop.
In early March, nine thieves appeared in the glass workshop, stealing Master Cheng's skills. Master Cheng killed the nine thieves, and hired nine more people from soap workshops and textile factories to work in the glass workshop, earning three to two months a month.
Tang Dong is one of these nine lucky people. What he does in the glass workshop is to add a powder to the glass liquid. This is very simple, just pour the powder in from outside the kiln while the glass liquid is still hot. Tang Dong even
He didn't know what the powder was, and of course he didn't want to know.
Apart from the fact that the working environment is a bit hot, there are no disadvantages to this job. However, compared with the monthly salary of 30 taels, it is not a problem at all. The 30 liang monthly salary is enough for Tang Dong and his family to live a good life.
As soon as Tang Dong reached the entrance of the alley, three children who were playing in the alley rushed up and shouted: "Daddy is back!"
"Daddy!"
Tang Dong's family used to be poor and he got married late. Now his eldest daughter is only seven years old. At this time, the eldest daughter is holding Tang Dong's legs, and the two younger sons are spinning around Tang Dong, calling daddy constantly, which makes Tang Dong's face full of joy.
.It is a day when all the girls here are well fed and can play happily, which makes people feel comfortable.
Tang Dong took out a few pieces of No. 1 Candy from his arms and handed them to his eldest daughter, smiling: "Here are the candies for you!"
The eldest daughter clapped her hands happily before taking the number one candy. The two younger brothers saw that their sister had candy in her hand, and immediately stopped and looked at her eagerly. The sister thought for a while, one, two, three, four
Di counted the candies and said happily: "Three pieces for each person!"
She took three pieces to her younger brother, and another three pieces to her second brother. Then she happily grabbed the candies and was not in a hurry to eat them. She seemed to be enjoying the happiness of having candies in her hands.
When Tang Dong saw his daughter's well-behaved appearance, he felt happy and picked her up. He walked into the house with his daughter in his arms and saw the boss of the Jie family who shared a house with him, learning calligraphy there.
A brush without ink, copied repeatedly on the copybook given by the private school teacher.
Tang Dong stood aside and looked at it. He didn't understand what the character was, so he smiled and said, "Boss Xie, what character did you write?"
Boss Xie said: "What I wrote is the word 'righteousness'! Can't you understand it?"
Tang Dong touched his face and said, "Why do you want to learn this?"
Boss Xie said: "Have you not noticed? Half of the managers promoted by the boss are literate. Once they are literate, it will be very different in front of the boss!"
Tang Dong spat: "You still want to be a supervisor? Don't you want to look in the mirror?"
Boss Jie laughed, ignored Tang Dong, lowered his head and continued to practice calligraphy.
Tang Dong put his daughter down and said to Boss Xie: "Boss Xie, I made up my mind when I was working today. I want to take a loan to buy a house. I'm afraid I won't be able to share a house with you in the future!"
Boss Xie spat: "Look, look how proud you are. You have only been working in the glass workshop for a few days, but you no longer like the rented house and want to buy a house! Isn't it a big deal for three or two months?" Boss Xie raised his head.
, said disdainfully: "Remember the year before last when you first came to this house! How shabby your coat was? I don't even believe you if you say you're not a beggar!"
Boss Jie glanced at Tang Dong's eldest daughter again and said: "At that time, your three children were sallow, skinny, and skinny! It seemed like they would be broken at the slightest touch. In just over a year, they have grown into fat little ones one by one.
Girl!"
"What did your women call you back then? They called you Tang Dayan! Now I know how to call you 'the head of the family'! This guy has changed so fast!"
Tang Dong smiled and said: "It's all thanks to the good job given by my boss!"
Mr. Jie laughed and said, "You said that your woman knows that you want to buy a house. Is she happy to have her own house or is she worried that she doesn't have enough money?"
The two were talking, and Tang Dong's wife, who was spinning upstairs, heard it. She ran out and shouted in surprise: "Master, are you going to buy a house? We are going to have our own small villa?"
Tang Dong glanced at the boss and smiled.
After making reading glasses, Li Zhi started making telescopes again.
Telescopes are essential items for marching and fighting. They can see things miles away and seize opportunities. Of course, they are products that need to be manufactured first. Li Zhi had learned about Kepler telescopes before traveling. The structure of this telescope is very simple, with only two
The combination of a convex lens and two total reflection prisms can magnify distant objects dozens of times.
This simple telescope is enough for Li Zhi's current needs.
On April 3, Li Zhi hired jade polishing craftsmen and asked them to grind an 80 mm diameter convex lens objective lens and a 30 mm diameter convex lens eyepiece according to Li Zhi's drawings, and also grind two total reflection prisms. Lens grinding
After that, Li Zhi measured the focal lengths of the two lenses, and asked a coppersmith to make a copper tube with a larger front and smaller back, with a fold in the middle. He installed the objective lens, prism and eyepiece according to Li Zhi's drawings.
.
After it was done, Li Zhi raised the telescope to the city wall and took a look. He found that the telescope was completed and he could see the small scenery in the distance.
Li Zhi estimated that although the Kepler telescope has a simple structure, its magnification is at least twenty-five times.
At this time, the Western telescope had just been invented and was expensive. Very few people used telescopes in the Ming Dynasty. The telescope did not have a unified Chinese name. Li Zhi simply called it a telescope.
With the telescope, the scout's job will be easier. In the future, the scout will stand at a high place and use the telescope to scan, and can monitor the movement within more than ten miles. The need to rush to the enemy's vicinity and fight with the enemy's scouts will be relatively reduced. In fact, the need to rush to the enemy's vicinity and fight with the enemy's scouts is relatively reduced.
Li Zhi's soldiers are not very capable in fighting, and their close combat ability is much worse than that of the Tatar scouts. Even the scouts of the bandits are better in combat than Li Zhi's scouts. Once a fight breaks out, Li Zhi's scouts are often unable to
Get close to enemy troops.
Having a telescope can alleviate this problem to a great extent.
Not only that, the artillery can also benefit from this telescope. With the telescope, the artillery shooting correction work will be much more accurate. In the future, the correction soldiers can stand at a high place and clearly see the impact point of the artillery shells several miles away.
Of course, with this telescope, the general can better observe the battlefield situation, which is of great benefit.
The market for reading glasses has not yet opened up, and sales are very low. Li Zhi asked the jade craftsmen who were grinding lenses to stop making reading glasses and make telescopes together, and make more for the scouts and artillerymen.
This telescope has high military value, so Li Zhi decided not to sell it to outsiders, but only to equip his own troops. If friendly forces need it, he can send a few as gifts if circumstances permit.
When Li Xing heard that his brother had made a telescope that could see far away, he immediately rushed over from the military camp and snatched one away. After getting the telescope, Li Xing climbed to the top floor of the Beicheng Tower and looked around at the outer city of Fanjiazhuang City.
Very excited.
