In the darkness, someone began to load the shell weighing more than ten catties into the barrel.

Because of the spiral rifling, this shell is rear-loaded.

The shell must fit perfectly into the breech, otherwise it will be considered scrapped.

The barrel of the gun was twelve times the caliber of caliber, and the maximum angle of fire was about 20 degrees, and the propellant had been changed to thundermercury, which was loaded at the rear end of the shell and fired by a firing pin.

The artillery shell is actually the most primitive howitzer two hundred years later, and this thing now has a term called flowering shell.

Of course...... The flowering shell of black powder and the flowering shell after the appearance of yellow powder are completely different things, and this shell is not only mixed with yellow powder, but also mixed with a large number of steel balls.

This shell alone...... At the moment, in the Crafting Bureau, only seventeen craftsmen can make it.

Industrial production does not exist, the principle of Zhang Jing understands, but the level of manufacturing, can only be improved step by step, in order to create this thing, it is necessary to train skilled craftsmen, no matter how precise things are, in the end they can only be made by their hands, this is as if there will always be ingenious handicrafts in ancient times, such as horses stepping on Feiyan, when the Han Dynasty, there can be this wonderful thing, but in fact...... It's made little by little by craftsmen.

Seventeen craftsmen, the limit of one person is to make eight or so shells a day, and the daily output is hundred, and out of a hundred, at least more than forty are scrapped products, so that the final output of cannonballs can be maintained at about fifty, and now...... Zhang Jingyi brought all the output in the past few months, and planned to be ruthless.

After everything is ready.

Artillery positions everywhere were not in a hurry to open fire immediately.

Instead, an artillery observer first held up the binoculars, and then gestured to the people next to him.

The man began to blow the whistle.

The whistle blew.

Followed by...... Somewhere......

Jerked...... The barrel of one of the guns spewed flames.

Bang......

In the dark sky, a flash of lightning flashed.

The roaring sound of cannon almost broke everyone's eardrums.

The earth also lifted up dust.

In the celestial dome, the trajectory of the cannonball crossed a perfect arc.

Then...... The artillery observer had already raised his binoculars, motionless and observing the tail flame of the shells, and occasionally, holding a charcoal pen in his hand, began to record on a wooden board.

The cannonball finally ...... fell not far from the military formation, and immediately followed ...... Boom...... A ball of flame exploded.

This loud noise suddenly broke the dawn.

The walls of the army seemed to tremble.

It was originally a dark military town, and countless lights were lit up at once.

But...... This first shot did not hit the military town.

The shell observer ignored the noise, held the binoculars, kept observing, and then ...... He took out the map, marked the general directions, and then, after a simple calculation, began to make one gesture after another: "Correct the shooting table...... The muzzle of the left artillery array was raised by an inch......"

He gave one order after another: "The position of the No. 3 artillery group remains in its original position. ”

…………

One command after another.

Observers continued to measure.

This is a set of artillery firing calculations that were finally converted based on test data again and again.

After all, the accuracy of artillery has improved a lot, and it is already possible to roughly calculate the point of landing.

Every shell is worth a lot of money, and because of this, I have extremely high requirements for accuracy.

Many of the artillery training teams were transferred from other training teams, and many of them had a certain talent for mathematics.

In the past, everyone thought that this war and soldier still had to learn arithmetic and writing, but in the eyes of many people, it was like a military academy deliberately pretending.

At least in this era, Mo is an ordinary soldier, that is, a low-level military attaché, and the demand for culture is not high, only senior generals need to read some military books.

On the contrary, military schools do not learn much about the so-called art of war, but have high requirements for basic education.

Now, many students are discovering the role of basic education.

The various artillery positions began to respond, and they whistled.

Followed by...... The instructor of the artillery training team gave the order: "Open fire." ”

A sharper, tighter whistle sounded.

All of a sudden, the tension became there.

The other teaching teams have begun to tacitly stuff tampons into their ears.

…………

And here in the city tower, a roar has already awakened everyone, but fortunately, soon, everyone calmed down again, obviously, the other party missed.

Tan Maoxun was awakened, and he hurriedly took a team of military attaches and personal soldiers to the city tower, and he said angrily: "What happened? ”

"Go back to the general, put artillery under the city...... It seems that it is ready to attack. ”

Tan Maoxun sneered: "Could it be...... They still want to attack at night? Is this crazy? Let our artillery be ready, and when they are killed in the city, we will give these dogs a little bit of power, and let the guards also be ready, and once they fail to attack the city, we will take advantage of the situation to hunt down! ”

"Yes."

Tan Maoxun thinks there shouldn't be any big problems.

After all, the other party's firecracker is said to be very powerful, and there is a kind of artillery that is not bad, but the range is too short, and it will not have any effect at all against a city wall like himself, and on the city wall, there are also a lot of artillery, although these cannons were cast in the Jiajing period, the power is not trivial, plus there are many people in the city, these people really eat the bear's heart and leopard gall, and they are capable of attacking the city.

He was about to leave.

Then...... But I saw a group of scholars arguing with a few guards: "Bold, I have come to help in the war, who dare to stop me." ”

Tan Maoxun looked at them, smiled bitterly, and hurriedly ordered people to let them come over.

But it was Wang Shimin and the others who came in a hurry, they didn't sleep, this ghost place has poor drinks, women are ugly, even the residence, it is also very bad, at this time they heard the movement, so they came together.

Wang Shimin said: "General Tan, how is it?" ”

Tan Maoxun said: "I don't know the plans of the thief army at the moment, maybe it's just harassment, or ......."

"General Tan, it's time to send troops, thieves are rampant, deliberately provocative, it's time to give them a little bit of power, our army is ten times the thief army, how can there be a reason that the turtle can't shrink, the big husband is alive, he should make immortal merits, if the general is still so cautious, it is better to let the students and others, lead a team of elite soldiers, and behead the thief chieftains under the city......"

A group of scholars were enthusiastic and applauded, and some even clapped their hands and said: "Brother Wang's courage is admirable, not bad, not bad, we are the teacher of benevolence, and the thief chief is tyrannical, as long as we fall from the sky, the thief will definitely lose his heart, these are all powerful people, not enough to ......"

The word of fear has not yet been spoken.

Suddenly......

Distance......

Or is it far away......

Something strange happened.

Something like lightning flashed away miles away.

Followed by...... Thundered...... Thundered......

The earth shakes and the mountains shake.

On top of the walls...... He seemed to be starting to tremble, too.

A lot of dust began to fall from the tower.

The deafening sound of cannons, in this quiet night, was heard here very clearly, like thunder rolling in the sky.

Followed by......

They could clearly see that under the night sky, countless cannonballs, like meteors, flashing tail flames, were coming in the direction of here.

As soon as they heard this terrible movement and looked at the meteors in the sky, everyone was shocked at first.

Subsequently, the scholar who admired Wang Shimin was already holding his head, and took the lead in lying on the ground, trembling in two ways, and shouting: "Mom, ......"

The one who spoke wailed in horror.

And that Wang Shimin was also frightened, he turned around in a panic to escape, but found that he was in the aisle of the city wall, which was narrow.

"What...... What's up...... That...... What is that? Wang Shimin pointed to the sky and shouted.

The sound of the cannonball, which was whistling and crackling through the air, became clearer and clearer.

Tan Maoxun couldn't imagine what was happening in front of him.

In his imagination, if this is artillery, then it is impossible, the other side can't see the shadow, at least a few miles away.

What artillery in the world can shoot so far?

But...... This strange thing happened right in front of my eyes.

He hurriedly said: "Don't panic, don't panic......"

Tan Maoxun pressed the handle of the knife on his waist.

After all, he is still a military attaché, and he still has a little bit of courage, and he knows very well that if he panics at this time, then it will be all over.

He reassured the crowd: "We are here with an impregnable wall, and we cannot die......"

His words...... It seems that there is still some effect, at least ...... Let the pro-soldiers and scholars who were already in a panic ...... It seems to make sense.

As a result, although many people shrank up, there was no much confusion.

Immediately after, countless cannonballs swept over his head.

Followed by......

Bang......

Bigger bang ...... Exploded in the middle of the formation.

The fire was full of light, and the dazzling light almost pierced the eyes of blind people.

The huge roar made people realize that the power of this artillery was far beyond everyone's imagination.

Not only that, but when the light gradually fades, it can still be seen...... At the location of the dropped bomb, dozens of people were blown away in an instant, and after the shell exploded, a crater emitting black smoke was revealed, surrounded by stumps and broken arms.

Even the people who were dozens of feet away were unfortunately shot by shrapnel, and they let out a scream like killing a pig.

But......

It's just an appetizer!

All...... Just the beginning.

One by one, grenades fell all over the formation...... Suddenly, there was fire everywhere, the whistling of the cannonballs, and the flames that filled the sky.

A cannonball, directly blowing up the Midtown Tower.

The wooden castle tower collapsed in an instant, burning off the small half, and under the castle tower, only the remnants of the corpse were left with thousands of holes.

Tan Maoxun: "......"

He watched in disbelief, as if his eardrums had been punctured, and he couldn't hear anything clearly, just buzzing.

A nameless fear also rose.
