Shi Tianze was surprised and then realized that Marshal Yang Miaozhen had really kind to him at the beginning, and it could be said that he was very merciful.

If he had used such a cannon lineup when attacking Hejian Mansion, how could Shi Tianze have his life?

Li Muyuan, who was standing beside him, saw Shi Tianze's eyes falling down, and his beards were trembling with shock. He also raised his eyebrows at his teacher with a smile.

It seems that this artillery volley is more convincing than any words. Now Shi Tianze has no other thoughts except for serving the commander wholeheartedly!... While the cannons fired in the city, Bolu outside Gubeikou City was also surprised.

Of course he knew that the range of Tongzhou military artillery was much further than his Mongolian military iron artillery.

However, this time Bolu boldly arranged the artillery position a mile away from the city, but he had already thought about it.

The first thing is that his artillery can only shoot so far - this is the main reason.

Secondly, its iron cannons will not be destroyed by enemy cannons, not to mention that he has built those stone walls to block the opponent's burning bullets.

Finally, another reason is that Bolu felt that there would not be too many Tongzhou military artillery in Gubeikou City.

Because at this time, Gubeikou was rushed by the Tongzhou army and occupied it quickly, and it did not take too long.

The Tongzhou military artillery also has a common feature with the Mongolian military artillery, which is that it is extremely heavy and inconvenient to transport.

You should know that most of the journey from Huanzhou to here is Mongolian grassland.

Bolu can use countless strong horses to pull large carts and drag cannons forward.

But behind Gubeikou is the Yanshan Mountains, and it is not that easy for the Tongzhou army to transport artillery.

So Bolu was determined to have a very small number of Tongzhou cannons in Gubeikou, but when the other party fired, Bolu was immediately startled! How could this be the sound of cannons that more than a dozen or twenty cannons make?

Looking at the smoke and fires rising from the city, the number of artillery opposite was at least 200! Before Bolu could be surprised, the shells opposite fell on his artillery position... dozens of feet away in front! I'll go! The artillery of the Tongzhou Army was so close?

At this time, Bolu seemed to fall off his horse suddenly, but found that he was not only safe, but also picked up an ingot of gold.

He suddenly went from panic to ecstasy! The artillery shells fired by the Tongzhou army were far from reaching the position of his artillery.

Instead, he bounced jingling in front of his position, leaving a large area.

Of course, Bolu didn't believe that the shooting distance of Tongzhou artillery was only so far.

Because he had seen with his own eyes how the enemy's artillery fired at his army five miles away in Laotieshan.

So, Bolu can only explain the current situation with one answer, that is, there is a problem with the level of the gunners of the Tongzhou Army... Alas?

No! Just as Bolu was ecstatic to think of this, he suddenly discovered that a burst of smoke suddenly rose from the places where the Tongzhou army shells fell! After the large area of ​​shells fell in front of the Mongolian army's positions, the smoke began to rise in an instant.

The fog was as thick as milk. It was as thick as cow's milk. It was spread everywhere at the beginning. In an instant, it formed a smoke wall between the Gubeikou city wall and the Mongolian army's artillery position. Because the Tongzhou army was originally fired with smoke bombs, the first round of artillery bombings of Shen Mo's artillery was not to kill the enemy, but to block the sight of the Mongolian army's artillery aiming!... Shen Mo ordered the time to fire the artillery very accurately, just as all the enemy artillery had been pushed into the compartment made of stone walls, but there was no time to aim.

However, this made the Mongolian artillery operators only know the approximate location of the city wall, but could not train the artillery to the point where they aimed at the city head.

In Gubeikou City, Shen Mo turned around and smiled at Shi Tianze, and then ordered his artillery troops: "Follow the calibrated shooting, fifteen blooming bullets... fifteen shots of fire!"

Under Shen Mo's order, the Tongzhou artillery wheel on the Gubeikou city wall opened its arms and began to pour shells towards the enemy! Now, Shen Mo's artillery tactics have finally been completely presented to all the generals of the enemy and us.

...Outside the city, the smoke on the Bolu artillery position not only obscured the Mongolian army's sight, but also tightened the sight of the artillery at Gubeikou.

But the Tongzhou army artillery soldiers didn't care about this at all, because when the Mongolian army built the stone wall last night, it was equivalent to setting a goal for them.

Each of these Tongzhou military artillery groups received a list of shooting numbers of their own artillery.

This is the position of the enemy artillery that the artillery staff calibrated after careful surveying and mapping.

At this time, Shen Mo's painstaking efforts to cultivate technical artillery since the beginning of his artillery unit were established, and finally developed the results! Compared with the artillery of the Tongzhou Army, how could those Mongols know what a trigonometric function is?

So when the Mongolian army outside the city was dizzy and could not find the target at all.

However, the Tongzhou army artillery on the city was pressing the shooting table and shooting at the bottom in an orderly manner.

This artillery is called "blind shot" among the people, and is usually used when bombarding enemy troops at night and under cover (such as mountains).

Of course, this shooting method requires a lot of preparation in advance.

First of all, the enemy artillery positions on their own side are fixed, which means that the height of the city wall at their Gubeikou must be measured.

Secondly, the enemy's target is also fixed. In this regard, Bolu built a large stone wall very considerately and set the target for them.

At this time, the artillery staff can divide the enemy target into countless small pieces on the map, and each artillery group is responsible for one of them.

These artillery operators can easily accurately shoot the artillery shells into the area they are responsible for by adjusting the pitch and directional aircraft according to the position on the various tables.

After that, the Tongzhou military artillery on the city immediately entered the free shooting. This time it was no longer a volley but a force shooting. The sound of artillery fire from more than 200 artillery pieces was almost continuous! The shells, like heavy rain, flew out of the cannon chamber, and flew across the sky like a meteor, plunged into the thick fog.

Through the thick fog, you can clearly see the general position of the artillery position opposite, and the stars are constantly emitting fire.

Every flash of fire there represents a flowering bullet raging on the enemy's artillery positions.

The sound of the Mongolian army came from afar, and the clanging sounds made by shrapnel hitting the iron cannon.
