On the eighth day after the rain in the valley, at night.

Dark clouds covered the night sky, and the seaside tidal flats were pitch black.

With a hint of coolness, the light rain was falling in a gentle manner, causing ripples on the tide.

There is not even a shadow of seabirds on the muddy tidal flats, and the villagers will not go out on this wet and cold rainy night.

Wang Youzhen waited for several days in a row, and finally waited for such a good weather.

In the past few months, Wang Youzhen has walked from the village to the salt pan over and over again, often walking over with his eyes closed, for today.

How to walk, how many steps to take, how many turns, where to stop.

It's all in the know.

The sea breeze howled.

The cold rain blew on Wang Youzhen's body, and the muddy ground sank deep into the soles of his shoes, making it difficult for him to walk.

Go straight, turn, flip ......

After two incense sticks, Wang Youzhen came to the vicinity of the salt field with difficulty, reached out and touched the rain on his face, and scanned it seriously.

It was pitch black, and no one could see what he was going to do next.

After Wang Youzhen cautiously confirmed it again and again, with his amazing memory, he walked step by step from the muddy tidal flat ground to the salt trough.

Stretched out his right hand and touched the iron grinding disc that should be in front of him, and sure enough, he touched it.

Wang Youzhen felt the coldness from the palm of his right hand, put the sealed clay pot in his left hand on the iron grinding plate, and forcefully removed the lacquer.

Holding the dilute sulfuric acid clay pot in both hands, it was slowly poured on top of the iron grinding plate.

The dilute sulfuric acid and iron immediately underwent a neutralization reaction, and the heavy iron grinding disc continued to corrode, and hydrogen gas was produced at the same time.

After a bag of cigarettes, the iron grinding disc weighing a thousand catties appeared with small holes, just enough to reach into a hand.

completed the feat that even if Xiang Yu was reborn and Li Cunxiao was alive, it would be impossible to accomplish.

Take a hundred taels of silver from under the thousand-pound iron millstone.

Wang Youzhen's tired face couldn't help but smile, and he said something in his heart.

It's all about the power of science.

opened the hole, took out a total of six pounds of silver, took it out one by one, held it in his arms and began to return the same way.

Fortunately, Wang Youzhen practiced martial arts with his grandfather who retired from the border army since he was a child, and he didn't feel too tired, and he arrived home in less than two sticks of incense.

Walked to the village of dilapidated mud houses, came to the door of the house, pushed open the tattered wood door and walked in.

Wang Youzhen put the silver into a clean clay pot and buried it in the corner of the backyard.

By the time all this was dealt with, it was already dark.

Wang Youzhen wiped a handful of sweat and rain from his face, hurried back to his small earthen house, and wiped his body as fast as he could.

There are no antibiotics in Daming, and minor illnesses such as colds and fevers are the most life-threatening diseases in Daming.

Many officials who are not short of medicine will die on the bed because of a cold disease, and the poor people who can't even eat enough can only wait to die.

Wang Youzhen wiped his body clean, lay on the bed and fell asleep.

Sleep until noon.

The light rain outside also stopped, and Wang Youzhen got up to drink a bowl of coarse porridge mixed with japonica rice bran amid the shouts of his mother.

Japonica rice is much more unpalatable than white rice, and the bran is the husk and crumbs of wheat that have been milled, and the throat tingles when swallowed.

Needless to say, the taste is not much better than pig food.

But there is no way, white rice is too expensive, and it has risen to one or two or three coins of silver and one stone.

Japonica rice costs only one tael of silver and one stone, and bran is sold for only five dollars of silver and one stone.

Wang Youzhen drank the japonica rice bran porridge in the coarse porcelain bowl without saying a word, and he was not at all dissatisfied, and his family could at least be full.

Many salt dredders can't afford to eat even a penny of silver and a stone of chaff at home, and they only eat one meal a day.

Wang Youzhen put down the dishes and chopsticks in his hand, said "Mother, I went out", and walked to the ancestral hall of the Wang family.

Walking on the muddy dirt road in the village, Wang Youzhen began to think about the next big money plan.

Any industrial machinery in the early industrial revolution could earn a lot of money in Daming.

But because those new machines are too profitable, with Wang Youzhen's current status, there is only one way to die if he is discovered.

About the next step after the first pot of gold.

Wang Youzhen thought about it for many days, and finally selected an industrial machinery that was easy to conceal, and developed steadily step by step.

"Kill!" "Kill!" "Kill!"

Not far from the ancestral hall of the Wang family, Wang Youzhen's thoughts were broken by a childish shouting of killing.

Several half-grown teenagers were practicing the battle formation sword skills of the northern border army, and these five teenagers were very conspicuous.

However, at the age of sixteen or seventeen, they are all tall, and Wang Youzhen has an average height of 1.85 meters after visual inspection.

It's a pity that due to the long-term lack of food, the five tall teenagers don't have much meat on their bodies, otherwise they will all turn into tigers and bears, and become humanoid bears.

These five teenagers are Wang Youzhen's cousins, and they are also the only places where he is more relieved after coming to Daming.

At least don't worry about being bullied by others, if anyone dares to bully him, the eldest son and eldest grandson, the five teenagers rushed over as soon as possible.

The five teenagers saw Wang Youzhen, who was also tall, coming over, put down the wooden knife in his hand, and shouted together, "Big brother." ”

Wang Youzhen nodded and asked, "Four bears, is grandpa in the ancestral hall?" ”

Wang Sixiong, who ranked fourth according to age, replied: "Grandpa is in the backyard of the ancestral hall. ”

Wang Youzhen waved his hand, motioned for several cousins to continue practicing, and walked to the backyard of the ancestral hall alone.

The ancestral hall of the royal family is just a simple earthen house, in which more than a dozen ancestral tablets are placed.

The so-called backyard is nothing more than a yard surrounded by a fence.

Wang Youzhen's grandfather, Mr. Wang, is working as a carpenter in the fence to make a living, making rakes, zigyuan plows and other farm tools for Yanding in the same village.

After retiring from the border pass, Mr. Wang has been using this exquisite carpenter skill to support his three sons and ten grandchildren over the years.

Wang Youzhen bypassed the ancestral hall earthen house to the backyard, and saw that his grandfather, who only had one right arm left, was planing the quyuan plow, and his eyes couldn't help but be a little sour.

A few months ago, Wang Youzhen was swept into the deep sea by a big wave, and he was almost out of breath after being rescued.

The mother lay on the side of the wooden bed, crying to death.

My father and two cousins ran thirty or forty miles overnight and invited a Lang Zhong.

The grandfather, who was squatting at the door without saying a word, knelt on the ground and kowtowed heavily.

Before this, he had killed the Eight Banners Tartar at the border, and his right arm was cut off and he didn't cry out in pain.

I have never bowed my head in my life, and I have never begged anyone.
