"Uncle, I know an old man who specializes in treating lack of middle qi, and I will introduce it to you later?"

"Go, go, go...... Lao Tzu is majestic! ”

"Uncle, I have done what you ordered yesterday - twelve or thirteen miles away from the northern suburbs of the city, there is a 'Xiangming Mountain', there was a layman who had lived in seclusion in the valley before, and after he left, a few grass houses were deserted, where there are far away from the world, there are mountains and rivers, which is exactly what you want."

"There are no bandits in this Xiangming Mountain, right?"

"That can't be, we have to pass by the foot of the mountain when we go to the countryside, and we will be safe."

"Very good, and lead the way."

Song Che loaded copper wires, fireworks, and all materials and tools into the carriage, and after lunch, he went to the northern suburbs of the city with his field mates.

Ten miles of spring breeze into Xiangshan.

Jiangnan is really a good place to go, and even the name of the mountain has achieved such a poetic feeling.

The scenery of Xiangming Mountain is beautiful, along the way often accompanied by birds and flowers, the mountain road is not bumpy, less than half an hour, Song Che found a valley dwelling.

Withered vines and old trees, small bridges and flowing water, three thatched huts and small courtyards, the style is clean and elegant.

It has been abandoned for a long time, and the grass house is inevitably dilapidated, so Song Che cleaned it up simply, and he didn't spend the night here anyway, and he was about to settle down.

Once you've landed, it's time to get to work.

The first is to assemble firearms.

The precision of the parts polished by skilled craftsmen is naturally not to be said, and it is not difficult to put together the general barrel, handle, and magazine.

Modern firearms trigger the primer of the cartridge case through the striker, ignite the gunpowder in the shell, and generate high temperature and high pressure to push the warhead to do work and shoot. Except for pulling the trigger, the rest of the process can be done automatically, so it is called an "automatic pistol".

However, the ancient black powder had very low activity and could not be excited by collision, so it could only be ignited manually, so there was no automatic one, and the bullet and gunpowder had to be separated.

Stuff the bullet into the front of the magazine, fill the gunpowder into the back of the magazine, and place a flint at the tail of the gun;

If there is no spring, a rubber band is used instead, the rubber band is hooked to the striker, the trigger is connected through the inside of the handle, and the striker is manually pulled down, and the trigger is tightened at the same time, so that the pistol is equivalent to being loaded.

When firing, the trigger is pulled, the rubber band is relaxed, the striker quickly rebounds, and the impact of the flint produces a spark, igniting the black powder in the magazine, and the gunpowder releases energy and pushes the bullet out of the barrel.

The traditional process of fire guns is certainly not able to achieve automatic bursts, but there are six bullet slots in the revolver's magazine, and as long as the hand speed is fast enough, it can also shoot in bursts.

After the manufacturing idea is clear, the next biggest problem is gunpowder - the filled gunpowder has no cartridge case, if the amount is not well controlled, the light will blow up the bore, and the heavy will blow up the hand.

The power of ancient black powder still has to be carefully studied.

Song Che dismantled a roll of fireworks alone, extracted about a pound of black powder, sealed and loaded it in two jars, and then dipped it in powder with fine linen, and kneaded it into a lead to place the mouth of the can, so that a simple homemade bomb was completed.

Let's see how powerful it is.

Song Che found an open space by the stream, buried the jar in the rubble, stretched the lead to one foot, lit the lead with a lighter, and quickly retreated, hiding behind a dead tree to watch what happened.

The lead of the "Zizi ......" wrapped in the powder of the medicine accelerated the burning.

Ten breaths later, the lead burned out—

"Boom!"

With a loud bang, the jar exploded instantly, and the rubble flew everywhere, several of which were embedded deep in the trunk of the dead tree.

The sound of explosions echoed through the valley, startling a flock of birds and billowing smoke into the sky.

Song Che buckled the gravel on the trunk, pursed his lips and nodded, the power was considerable, and he walked to the explosion point again, and a half-foot shallow pit had been blown out of the ground.

Half a catty of black gunpowder has such power in a porcelain jar, if it is changed to a harder container, and then mixed with some iron nail slag, the killing range can be expanded by at least three times - within a radius of three zhang, even if you don't die, you will definitely be seriously injured.

In fact, the bomb is very rough, as long as you pour gunpowder into it, the power will not be much worse, but the bullet is completely different, the most excitation gunpowder is only the amount of fingernails, with the current power of this black powder, even if the warhead can be pushed out, it will definitely not be far away.

The power of gunpowder often depends on the content of "fire nitrate" in the ingredients, and these black powders are all taken from civilian products such as fireworks and firecrackers, which are controlled by the government, and the fire nitrate content is definitely not high.

If the proportion of fire and nitrate can be increased, the power will inevitably be even higher.

Fire nitrate is everywhere in life - for example, the "hoarfrost" on the stone house wall and the white powder around the manure pit are all raw materials for fire and salt.

In addition to extracting saltpeter from ore, the ancients would even "boil" to extract nitrate, don't look at the dirty manure, it contains a lot of energy, the most representative of which is "saltpeter" and "biogas".

Today, the guns are assembled first, and when you go home, you will collect more saltpeter, and after improving the power of gunpowder, it is not too late to practice shooting.

The valley is quiet, just in time for the sunshine, the breeze is not dry, there is a clear spring flowing, birds singing and flowers, Song Che moved the table, set it up in the shallow stream, and then took off his shoes and socks, while soaking his feet, while operating.

I don't know how long later, suddenly there was a numbness under his feet, as if something was scratching the soles of his feet, he looked down, and was so frightened that he almost lost his soul!

In the stream, a severed arm was impartial and stuck at his feet!

"Hold the grass!"

Song Che had 10,000 grass and mud horses galloping in his heart, so he hurriedly gathered his feet and went ashore, holding the table and retreating.

How could this person who is not in front of the village and behind the store suddenly have a broken arm?

Looking at the upper reaches of the stream, a pale red turbidity stream winds like a ribbon.

It's blood!

Looking at the severed arm again, it was not swollen and soaked, it was obviously cut off just now.

"Bang ......"

The crisp sound of the sword intersecting is particularly pleasant in the valley.

It looks like someone is fighting, and it sounds like there's more than one person.

"What a obscurity!" Song Che scolded secretly, put on his shoes and socks and planned to leave this place of right and wrong, but unexpectedly, a strange and familiar accent came into his ears:

"Wow, wow, a sack, goga, goa!"

Song Che reacted for a moment, what is this special...... Isn't it Japanese?

This is Suzhou, how can there be Japanese?

When I thought about it, in ancient Japan, it was called Toei and Fuso, and the Japanese were called Wa people, Wako, and Liuko......

It's definitely not easy!

Listen to the sound of swords, getting closer and closer.

Song Che hid the table in the grass, and he hid behind a dead tree to observe secretly.
