Without the carriage, Song Che could only finish work early and return to Suzhou City on foot.
After returning to the city, Song Che disassembled the spear into its parts, went to the most famous blacksmith shop in the city, and customized twenty of them at a price of ten taels each.
"No matter which method you use, the workmanship must be fine. If it does not meet my requirements during acceptance, I will not settle the balance."
"Don't worry, uncle. I, Blacksmith Wang, have been making iron for more than 20 years and have never let a customer down. I guarantee that within half a month, the twenty pieces of ironware you ordered will be made exactly the same."
"If so, there will be many rewards!"
…
The next day, Song Che bought a new carriage and went to the tavern to buy twenty small wine gourds.
In the morning, he successfully detonated the first fire gourd, which was several times more powerful than the previous explosives. He also imitated the style of a grenade and installed a pull-ring device at the mouth of the gourd. Just pull down the buckle, and the flint can rub to generate sparks. , thereby igniting the fuse, so that the throwing time can be controlled, improving safety and accuracy.
Draw the gourd in the same way and use fourteen kilograms of dynamite to make nineteen fire gourds.
Gunpowder is extremely susceptible to moisture, so Song Che packed the gunpowder into a jar and sealed it tightly like pickles.
In the afternoon, we started making generators——
First make four small coils with copper wire, wind each coil 500 turns, then fix the coils on the wooden board at the four corners in turn, connect the copper wires end to end, then dig a round hole in the center of the wooden board and insert a round rod as a bearing , two magnets are fixed at the beginning and end of the bearing.
Although the principle is simple, the production details are extremely complicated. It took Song Che two full days to complete the prototype.
Connect the two copper wires to the mobile phone charging head, plug the data cable into the mobile phone appliance, and then rotate the generator bearing like a "hand tractor".
Shake the coil and use the magnet to cut the magnetic lines. As your hand speed gets faster and faster, the phone suddenly buzzes, indicating that it is charging.
It worked.
Once Song Che stops shaking, the phone will power off.
In just a short while, he was already exhausted and sweating profusely.
It is not difficult to make a simple generator, but how to obtain lasting power is the biggest problem.
Even modern power generation uses natural energy sources such as wind energy, water power, tides, and fire power. Among them, hydropower generation is the most common - using the potential energy of flowing water to impact the spiral device, thereby converting it into kinetic energy to drive the coil to rotate.
There happened to be a trickling stream in front of me.
On the third day, Song Che made a simple water windmill with wood chips and installed the water windmill on the generator bearings. Then he found a relatively turbulent water area in the valley and placed the generator on the creek.
The water flow hits the water windmill, causing the coil to rotate rapidly, and the generator starts to operate.
After Song Che charged his mobile phone, he sat by the stream all afternoon. When he picked it up and looked at the battery, he found that it was less than one-fifth full.
The voltage output in this way is enough to charge a mobile phone, but it is definitely not enough for a charging stick.
According to the principle, even if four 500-turn electric coils cannot produce the rated voltage, it will not be much different. The biggest problem should be the rotation speed of the electric coils.
The faster it rotates, the faster the magnetic induction lines are cut, and the higher the voltage it emits. Unfortunately, the bearings are made of wood, and the iron rotor craftsmanship is so advanced that it cannot be reproduced in ancient times.
For the current plan, one is to find ways to improve the lubrication of the bearings, and the other is to find more powerful hydraulic potential energy.
But no matter what, the generator is finally done.
While it was still dark for a while, Song Che collected some resin in the valley. Resin is a good insulator. After drying, it can be used as a wire covering or a socket.
"Huh..." Song Che shook off the sweat and looked up at the sky. The setting sun had already set over the mountains.
It has been six days since I moved into the thatched cottage. I leave early and come back late every day. I have not been involved in business. I have even neglected my beloved wife at home. It is time to end this seclusion and return to normal life.
Song Che loaded all the finished products and materials onto the carriage, locked the gate of the thatched cottage, and returned to Suzhou City at sunset.
…
After returning home, Song Che learned from the craftsmanship of the carriage wheel and passed the log stick with hot oil to make it smoother and tougher. Then he applied a layer of lubricating grease to the bearing mouth. Now, with just a gentle flick, the coil It can rotate about ten times.
The Shen family is a large family, with three landscape ponds. Song Che asked his servants to dig a small ditch to introduce the pond water into the channel from top to bottom, and then stuck the generators on both sides of the channel. In this way, the water flow continued to flow. The voltage emitted by the windmill is significantly higher.
With the battery capacity of Song Che's mobile phone, it can be fully charged in a matter of hours with normal voltage. Using this homemade generator will not be much slower. I think even if it does not reach the rated voltage, it is not far behind.
After the generator was completed, Song Che charged the electric baton late at night. When he got up the next morning, he checked and found that the battery was fully charged.
"Husband, are you going to become an alcoholic? Why do you always have a wine gourd hanging around your waist?"
"This is filled with beast whip wine. I will take a sip when I am thirsty."
"Then... give me a taste too!"
"Hey, don't try this lightly. This wine is very strong and will explode as soon as you drink it!"
Having money in your pocket, an electric baton in your sleeve, a musket in your arms, and a gourd in your waist is called a sense of security!
…
In the days that followed, the people of Daliang were immersed in fear.
The Hu tribe in the northwest conquered Xiliang. Every time they captured a city, they massacred another city. All the men were killed and the women were treated as livestock. It was a cruel and cruel situation.
Xiliang was the elite of the northwest army, but it was defeated and retreated. Dongliang and Beiliang could not be the gateway. Yongzhou was in danger, and Chang'an was also in danger.
Dijon in the north is pushed flat all the way to the outside of Humen Pass. Wherever you go, not a blade of grass grows. The Jingzhou Army fought a bloody battle with the enemy and suffered heavy casualties.
Humen Pass, Qingmuguan, and Shanhaiguan are the three major fortresses in the north. If one of them is broken, the north will be in danger. If the Sixteen Prefectures fall into the hands of Dijon again, the terrain of the Central Plains will be flat and there will be no mountains and rivers to deny them. With Dijon's heavy cavalry, If you drive straight in, you will not be able to protect the eastern capital!
In official history, the Northern Song Dynasty was exterminated in this way, which triggered the most unspeakable "Jingkang Shame".
It is not difficult to find that Daliang and Song Dynasty are almost mirror images of each other. What happens in the parallel world may be slightly different, but the general trend is definitely the same.
The Liang Dynasty will definitely be very difficult in the past few years.
"In my opinion, either the whole people will join forces and fight with them, or they will have to surrender and pay tribute to protect themselves, unable to defeat them again and again, but unwilling to accompany them! It's all the common people like us who are suffering!"
Every day at dinner, my father-in-law only needs two glasses of wine before he slaps the table, blows his beard, glares, and talks about important national affairs.
Who wants to be a slave to the subjugation of the country?
"Are you burned by the flames of war? Or do you have enough to eat or clothes to wear? Oh... you are so worried about the country and the people. Suppose the army is exhausted and they arrest you and send you to the army, will you go?" My mother-in-law has always held different opinions. She always thinks that everything is good if the family is good, the man is good, and the children are good.
"A woman's opinion!" My father-in-law retorted: "I am already old, why should I go to the battlefield? I am going to the battlefield, who will donate money to them? Who will pay high taxes for them? The most irritating thing That is, I have donated so much money, but it has not achieved any results at all. In my opinion, it is probably because the corrupt officials in the government have enriched their own pockets!"
As he spoke, he looked at Song Che again: "Xianxiang, do you think I am right?"
"Ah, ah?" Song Che spit out the chicken bones and nodded repeatedly: "Yes, yes, yes..."
The mother-in-law immediately retorted: "What are you right about? You men are all drunk and hot-headed. After a battle, how many houses will be hung with white silk and how many women will be widowed?"
Song Che nodded: "Mother is right..."
"Hmph!" My father-in-law slapped the table: "If men don't have the blood to defend their families and countries, how can you women have a peaceful life? You are just widows, but we will lose our lives!"
"Oh, don't say 'you'. A bandit robbed a boat and I was so scared that I couldn't get out of bed for three days. If I go to the battlefield, the first person to raise my hands and surrender will be people like you!"
"you you you you……"
"Mom and Dad, we are full, please take your time..."
Seeing that the situation was not good, Shen Wenjun tugged on Song Che's sleeve.
Song Che whispered: "I haven't finished the bowl yet..."
Shen Wenjun whispered: "Eat again. There is no fighting at the border. Our family is going to fight first. Which side will you stand on when we see it?"
"Uh... I'm full too. Mom and dad, take it easy."
The two of them joined hands, rubbed oil on their soles, and slipped out of the dining room.
