In the darkness, someone began to load the shell weighing more than ten pounds into the cannon chamber.

Because of the spiral rifle, this shell is a rear-mounted one.

The shell must be closely matched with the barrel. Otherwise, it will be considered scrapped.

The cannon's body tube is twelve times the caliber, with a maximum firing angle of about twenty degrees. The launching medicine has been changed to thunder mercury, loaded at the back end of the shell and fired with a striker.

The shell is actually the most primitive howitzer two hundred years later. This thing now has a term called the flowering bullet.

Of course... the flowering bullet of black gunpowder and the flowering bullet after the appearance of yellow gunpowder are completely different. This shell is mixed with yellow gunpowder, but also with a large number of steel balls.

This shell alone...at the moment, only seventeen craftsmen can make it.

Industrial production does not exist. Zhang Jing understood the principle, but the manufacturing level can only be improved step by step. In order to create this thing, it is necessary to cultivate skilled craftsmen. Even the most precise thing can only be made with hands in the end. It is like in ancient times, which always appeared ingenious handicrafts, such as horses stepping on flying swallows. During the Han Dynasty, there were such magnificent things, but in fact... it was created bit by bit by bit by bit by craftsmen.

The limit of seventeen craftsmen is to build eight shells every day, and the daily output is 100. Of the hundred, at least more than 40 are scrap products. Therefore, the output of shells can be maintained at around fifty. Now... Zhang Jingyi brought all the output in the past few months, intending to make a ruthless one.

After everything is ready.

There was no rush to fire immediately in artillery positions everywhere.

Instead, an artillery observer first picked up the telescope and then made a gesture to the people around him.

The man began to blew the whistle.

A whistle sounded.

Then...somewhere...

Storm…A cannon barrel spewed out flames.

Boom...

In the dark sky, a lightning flashed away.

The rumbling sound of cannons almost broke everyone's eardrums.

The earth also raised dust.

In the sky, the trajectory of the shells drew a perfect arc.

Then... the artillery observer had already picked up the telescope and observed the tail flame of the shell motionlessly. Occasionally, he took the charcoal pen in his hand and began to record on a wooden board.

The shell finally fell into a place not far from the military formation, and then... a roar... a ball of flame exploded.

This huge noise broke the dawn.

The city walls of the military formation seemed to be trembling.

It was originally a dark military town, and countless lights suddenly lit up.

However... this first shot did not hit Junzhen.

The shell observer ignored the noise, held the telescope and kept observing, and then... took out the map and marked the approximate position. After a simple calculation, he began to make gestures after gesture: "Revise the firing table... The gun mouth on the left side of the cannon array is raised by an inch..."

He issued one order after another: "The No. 3 gun group position remains in its original posture."

…………

One command after another.

The observer continues to calculate.

This is a set of artillery firing calculation methods based on the experimental data over and over again.

After all, the accuracy of the artillery has been greatly improved, and the drop point can be roughly calculated.

Every shell is valuable, and because of this, I have extremely high requirements for accuracy. If it fails to hit the bomb, it will be a loss of blood.

Many artillery teaching teams are transferred from other teaching teams, and many of them have certain talents in mathematics.

In the past, everyone believed that when they were in war, they had to learn arithmetic and writing. In the eyes of many people, it was like a military academy deliberately pretending to behave.

At least in this era, not to mention ordinary soldiers or military officers at the bottom, they have little demand for culture. Only senior generals need to read some military books.

On the contrary, the military academies do not learn too much so-called military tactics, but instead have high requirements for basic education.

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

The various artillery groups began to respond and they whistled.

Immediately afterwards... the instructor of the artillery teaching team issued an order: "Fire."

A sharper and tighter whistle sounded.

For a moment, the place became nervous.

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

…………

And here at the city tower, a roar woke everyone up. Fortunately, everyone calmed down soon. Obviously, the other party missed the shot.

Tan Maoxun was awakened and hurriedly led a team of military officers and personal soldiers to the city tower. He said angrily: "What happened?"

"Go back to the general, fire artillery under the city... It seems that you are about to prepare for an attack."

Tan Maoxun sneered: "Does they still want to attack at night? Is this crazy? Let our artillery be prepared. When they kill to the city, they will give these dogs a little more powerful and let the guards prepare. Once their siege fails, we will take advantage of the situation to chase and kill!"

"yes."

Tan Maoxun thinks there should be no major problems.

After all, the opponent's muskets were very powerful, and there was also a kind of cannon, which was also good, but the range was too short and it would not have any effect on a city wall like himself. There were also many cannons on the city wall. Although these cannons were cast during the Jiajing period, their power was quite impressive. In addition, there were many people in the city, and these people were really brave enough to attack the city.

He is about to leave.

At this time... a group of scholars had a dispute with several guards: "Bold, I'll come to help the war, who dares to stop me?"

When Tan Maoxun saw them, he smiled bitterly and hurriedly ordered someone to let them come over.

However, Wang Shimin and others came in a hurry. They didn't sleep. The wine in this ghost place was poor and the women were ugly. Even the residence was very bad. When they heard the movement, they came over together.

Wang Shimin said: "General Tan, how about it?"

Tan Maoxun said: "I don't know what the thief army is planning now. Maybe it's just harassment, or..."

"General Tan, it's time for the troops to be sent. The thieves are rampant and they are deliberately provoking them. It's time to give them some strength. Our army is ten times more powerful than the thief army. How can we not be able to hide? A real man should make great achievements in life. If the general is still so cautious, it's better to let students and others lead a team of elite soldiers and kill the thief chiefs under the city..."

A group of scholars were filled with blood and cheered, and some people clapped their hands and said, "Brother Wang is brave, admirable, good, good, we are a benevolent army, and the thief chief is tyrannical. As long as we fall from the sky, the thief will be scared. These are all harsh people, and they are not worthy of..."

The word "Fear" has not been expressed yet.

Sudden……

far away……

Or very far away...

Something strange happened.

Things like lightning flashed and disappeared several miles away.

Immediately afterwards... rumble... rumble...

The earth shakes.

The city wall also seemed to start to tremble.

A lot of dust on the city tower began to swell.

The deafening sound of cannons was heard here in this quiet night, as if the sky was rolling.

Then...

They could clearly see countless shells under the night sky, like meteors, flashing with tail flames, heading towards this direction.

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

Then, the scholar who admired Wang Shimin was already holding his head and lying on the ground first, fighting with two fights, shouting: "Oh my God..."

The speaker wailed in horror.

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

"What...what...what is that?" Wang Shimin pointed at the sky and shouted.

The sound of the shell was a whistling sound, and the sound of breaking through the air was becoming clearer and clearer.

Tan Maoxun could not imagine what was happening in front of him.

In his imagination, if this was a cannon, it would be impossible that the other party would not see any shadow, at least a few miles away.

What artillery cannons in this world can shoot so far?

But... this strange thing happened in front of me.

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

Tan Maoxun pressed the hilt of the knife around his waist.

After all, he was still a military officer and was a little more courageous. He knew very well that if he was panicked at this time, then it would be all over.

He comforted everyone and said, "We are a wall of iron here, we can't die..."
