While more than 10,000 elite cavalry troops charged over, Cao Dingjiao's artillery battalion had already set up a position, quietly waiting for the impact of the tide on that line.

Cao Dingjiao's stature was relatively tall, much taller than most of the officers and men of the artillery battalion, and in order to observe the battlefield situation more conveniently, a mound more than one zhang high was temporarily piled up at the rear of the artillery battalion.

Cao Dingjiao was wearing an armor and a cyan cloak tied behind him, hunting and rolling in the cold wind of late autumn.

Ahead.

The sergeants of the artillery battalion, wearing brand-new red mandarin duck jackets, are putting the finishing touches on the Type 05 field gun, adjusting the firing angle against the gun table.

Further on.

Although thousands of Qin soldiers wore shabby mandarin duck battle jackets, they faced more than 10,000 elite cavalry troops galloping on horses with an unimaginable iron will.

No one showed timidity.

Death is like home.

Cao Dingjiao held a Western clairvoyant mirror, looked ahead with a calm face, and saw that the distance between the first-line cavalry tide was getting closer and closer, and there was a smile on the face of the national character.

Only by knowing each other and knowing oneself can one not be defeated.

Today, a discerning person can see that the thieves have enough of 200,000 troops to crush the Tongguan guards, and the thieves are unstoppable.

The kings of the thieves think so, the squires of Shaanxi think so, the Donglin Party thinks so, and even Chongzhen and the military leaders think so.

Cao Dingjiao read the thief's mansion newspaper more than a dozen times on the way over, and he knew him very well.

But he is more confidant.

It's easy to say that a sentence of step cannon synergy is involved, but there are many conditions involved in making it really happen.

First of all, a batch of standardized artillery is needed, which involves accurate measuring tools such as micrometers and vernier calipers, as well as a large number of skilled workers, as well as mechanical grinders.

Mechanical grinders, in turn, require prerequisites such as steam shops, steam engines, high-carbon steel, etc.

It is the completion of industrialization step by step that there is no standardized artillery until today, and one less link will make standardization a utopia.

After completing so many complex industrialization processes, there was a standardized artillery, and the next step was to need a group of artillery who were proficient in the cannon table.

The training of artillery also involves the ability of the chief general to manage the army, whether he has the financial resources to spend a lot of money for a long time to train artillery, solve the worries of artillerymen, and so on.

The birth of a famous general and the formation of a new set of tactics are not something that can be accomplished by one or two people, but the result of a class effort.

Cao Dingjiao is relying on Zhu Shun's industrialization dividends over the years, so that he can build a coordinated tactic of infantry and artillery step by step.

Could it be that the hard work of the industrial faction over the years is not enough to erase the gap between the two sides?

Can be smoothed.

Cao Dingjiao slowly put down the clairvoyant mirror in his hand, and only stared at the black tide rushing over the horizon with his eyes.

"1.5 miles away!"

"Wind speed level 4!"

"The temperature is low!"

The shouts of the general flag generals kept coming from their ears, and one after another orders shouted out from the mouth of the general flag commander, who had cultivated tactical literacy, and commanded the small flags of each Type 05 field gun.

According to the general flag, the small flags conveyed the instructions of the generals to the ears of every artilleryman, and the artillerymen kept making the final adjustments to the Type 05 field guns.

After being fed with a large sum of silver, the artillerymen have long been familiar with all this, and skillfully complete the parts they are responsible for, checking the gun table, adjusting the firing angle, putting in the gun gauge, and so on.

It's like gears moving delicately, completing their individual parts, which eventually set a huge machine in motion.

One mile.

Nine hundred meters.

Eight hundred meters.

Seven hundred meters.

Just when the tide of the first-line cavalry rushed to a distance of only seven hundred meters from the Qin soldiers.

Daming produced a scene that was enough to freeze history.

On a mound.

A blue-robed general.

A flat land.

Say a very ordinary command.

"Open fire."
