Da Wei Chun

Chapter 70
Li Chengzhi has always felt that he is a military rookie, at most the level of playing "Total War" and "Qi Chopping".

So since he knew there might be a war, he sharpened his gun for a few days.

In the space of iron making, he grabbed Li Song and taught him the military book for a few days.

There is "Liu Tao", there is "Grandson", there is "Grandson of Qi" (Sun Bin's Art of War), there is "Sima Law", there is "Wei Liaozi"...

Although he only got a rough idea, not even the fur, but his attitude made Li Song and the others very happy.

Jingzhou Li started his career with military exploits, and as his heir, and later the patriarch, his ability to eat must not be lost.

So Li Chengzhi can at least recognize what kind of formation Li Bo is practicing now: the goose formation in "Sun Bin Ten Formations".

This formation is the main attack, regardless of whether the formation is in a positive goose shape or a reverse goose shape.

At this time, Li Bo placed the anti-geese formation. It should have been changed to the name of the Crane Wing Formation when it was in the Song Dynasty.

This formation is not only the main attack, but also an encircling formation: the central army is restrained, its wings protrude forward, and when the formation is dispatched, it is like a crane flapping its wings and pounces on it. It is the wings, the main circle!
What Li Chengzhi wondered was, what was Li Bo's intention to practice this formation at this time?
You only have [-] soldiers, and others have at least [-]. What's the use of you practicing an encircling formation like this?

The war is imminent, and most of them are newbies. Shouldn't they practice some practical and effective things?
For example, how to defend, how to counter encirclement, how to defend and counterattack, or how to break through when surrounded.

Even if it doesn't help, you should also practice what kind of formation you should take to deal with enemies of different arms.

Of course, it is also possible that Li Song used this formation as the basis to teach soldiers how to change formations, but Li Chengzhi always felt that it was not so simple.

Compared with Li Song, Li Bo is much more aggressive. From the fact that he persuaded Li Chengzhi to take the initiative more than once, it can be seen that Li Bo is very gambling.

Li Song also mentioned: Li Bo is good at using the magic weapon!
Therefore, Li Chengzhi was a little worried. Li Bo's practice method might be plotting, one day he would be surrounded by rebels.

Thinking about it, it feels like a joke, let alone surrounded by [-], you can't contain a thousand enemies as well...

After all, no one knows a lot, plus there is no evidence, Li Chengzhi can't talk much, and Li Song will be back in six or seven days at most, and Li Bo can't play any tricks around, so let him toss first.

After watching for a while, he instructed Li Bo to let Ding Zu practice as much basic knowledge as possible, such as how to argue the flag and how to listen to the drum, and then Li Chengzhi returned to the mountain.

In addition to staring at making armor and pouring gold for Buddha statues, he has more important things: dispensing gunpowder.

For a professional like him, it is actually not that difficult to formulate this thing.

And he also got his hands on it.

When I was in my teens, the village was building a new canal, but I couldn’t afford large-scale machinery. When I encountered a sand and gravel layer, I could only blow it up with homemade gunpowder or blow it loose, and then dig it with iron.

At that time, every household sold potassium acid and ammonium acid fertilizer, so it should not be too easy to make this thing.

Potassium pinate also needs sulphur and precise formulation, and ammonium nitrate needs neither.

Take the sawdust and stir, put it in the pot and fry it.

At that time, Li Chengzhi was the one in charge of frying ammonium nitrate...

This thing is much more powerful than the gunpowder made of fire nitrate, but it has high stability. There is no high-explosive material to stimulate, you can't light it, so adults are very relieved.

For example: because ammonium nitrate is easy to get wet and agglomerate, when farmers buy it back, most of them are in one piece, which must be smashed before fertilizing in the field.

But this thing is not generally hard after it is hardened. It has to be smashed with a sledgehammer, and when it is smashed, sparks will pop up.

To switch to potassium nitrate, it's already on fire...

Detonators are not easy to make, and nitrocellulose is even more dangerous. With the guts, nitroglycerin can be produced.

Li Chengzhi didn't want to end up with a half-body disability or die young before he could enjoy life well, so he honestly chose to manufacture and sell potassium...

The method is also very simple: on the walls of pig and sheep pens, stables, and toilets, there will be bulging white soda, also called soil salt.

Then soak the plant ash in water, filter out the ash, then soak this thing in, filter it again, and finally wait for condensation to crystallize.

The salt comes out first, and then the fire salt.

Therefore, while Li Chengzhi produced dozens of catties of fire nitrate, he also produced dozens of catties of fine salt.

The kind of Bai Ruxue, there is no such thing in this era, and it will definitely shock Quan Dawei when you take it out...

To put it bluntly, it is all extracted from urine, and Li Chengzhi will not eat it if he kills him.

However, at this time, green salt can also be used as currency, just like silk and corn, and the price is not low.

Therefore, Li Chengzhi did not fall.

The proportion of gunpowder is easy to remember, and it is not difficult to granulate. I am afraid of getting wet, and I am afraid that static electricity will be generated by dangling it around. In addition, there are materials at hand. Li Chengzhi also rolled a layer of graphite on the gunpowder particles...

In fact, it is also possible to roll wax, but Li Chengzhi was afraid that the first time he gave birth by hand, he would not be able to control the thickness and affect the burning of gunpowder.

However, the fuse and the grenade seal are all wrapped in wax, so they are not afraid of rain.

For the mine shell, Li Chengzhi naturally used a cast iron can. Compared with the clay pot, the advantage is that it is not afraid of falling, but the disadvantage is that it is heavier.

As for whether it could explode, Li Chengzhi was not worried at all.

In the Ming and Chinese dynasties, the formula of gunpowder was not so precise, and the preparation method was many times rougher than his, and they all used pig iron shells...

Besides, it's all made, don't you know to try it?

Therefore, on the third day after Li Chengzhi inspected the barracks, the entire Kongtong Mountain heard a thunder.

Many villagers and village women who were making wooden armor, cutting arrow shafts, and sewing armor linings knelt down in fright.

Thunder in winter, or the bright sun?
Never heard of it.

In the hearts of these villagers, the phenomena that cannot be explained by reason can only be attributed to the gods and miracles...

Hearing the sound, as if it came from Nanfeng, Li Bo's complexion changed greatly, and he immediately mounted a horse and hurried up the mountain.

He thought it was a fryer...

In the past, when iron or pottery was smelted in Zhuangzi, there would occasionally be one or two incidents, and there were times when people were hurt.

But Li Bo had never seen such a big movement.

It doesn't matter if all the blacksmiths and potters are dead, even if those retainers and his two sons are dead, at most he is secretly crying a few times at night when no one is there.

But if Lang Jun had an accident...

There was no more blood on Li Bo's face, and he used all his strength to swing the whip.

In the front yard of the main hall, Li Zhang and Li Liang were watching a few copper craftsmen bake the gold paint on the Buddha statue with a blast furnace. When they heard the explosion, the copper craftsmen lost the iron bars in their hands in fright, and the iron Buddha fell down immediately. Smash the blast furnace.

They just thought it was an immortal who gave divine punishment...

Li Zhang's face was a little pale, and he muttered, not knowing what he was talking about, but Li Liang was not so scared.

"It's a little far away. It doesn't look like a fryer in the backyard, but rather like the back mountain?" Li Liang wondered, "What's the back mountain?"

"Apart from a cliff, what else can there be?" Li Zhang muttered, "But when I saw Lang Jun in the morning, it seemed that I was carrying something to the back mountain..."

Speaking of this, Li Zhang's eyes suddenly burst, his whole body trembled, and then he roared wildly, "It's Lord Lang, the one who struck the thunder is Lord Lang..."

Before he finished speaking, he ran away.

Where is the fairy and the thunder?

Li Liang didn't believe in ghosts and gods when he was a child, but he couldn't guess what happened, whether it was Li Chengzhi, so his face turned pale.

He scolded "idiot", and just wanted to catch up, but suddenly remembered that there were more than a dozen coppersmiths beside him.

Whenever one of these people runs away in chaos, the Li family will be sacked and wiped out...

Li Liang's eyes turned cold, and he pulled out his waist knife with a jerk. He pointed at Li Bo's two sons, Li Zhao, and Li Ming shouted, "Copy guy, watch carefully!"

As he spoke, he pointed at the group of coppersmiths again, "The one who dared to move, grandpa chopped you down..."
