The First Family of Tang Dynasty - Chapter 3002 The emperor of the Tang Dynasty did not want to accept my Goguryeo vote at all...

Goguryeo used nearly 100,000 soldiers and nearly 300,000 civilians to build the fortresses on the east bank of Yalushui, day and night.

In the eyes of this Goguryeo messenger who had experienced the Great Tang attack on the Liaodong city, it was simply a helpless struggle in despair.

Here, in this open area next to the Great Tang Emperor's Camp. There are more than one hundred artillery pieces like ferocious beasts.

Sixty of them look very sturdy and stocky, and the chassis also appears to be low. These were originally cast by copying the artillery of the Datang Navy battleship.

It is also the cannon that was first used in the expedition to Liaodong. It is heavy and must be moved to a carriage before it can move quickly.

There are also ten artillery pieces, and the barrels that are so thick that the eyelids jump, are pointing diagonally to the sky at this moment.

Those ten are the flying thunder cannons that the Tang Empire relies on most to conquer the Goguryeo army.

It's just that the nitrifying explosives that Cheng Sanlang used are no longer used by the Flying Thunder Cannons.

Cheng Saburo also brought some of that stuff himself, and he had already played it all, and the rest were all buried in the ground of Chengjiazhuang in Luoyang.

That's a good treasure that Cheng Saburo made by himself, how could it be lost all of a sudden.

Facing Cheng Sanlang with his hands spread out, Li Shimin could only pinch his nose and let the Flying Thunder Cannon use the shells of the black artillery.

Although the power is not as powerful as the nitrification explosive shells, the power far exceeds that of other artillery shells, which is also quite cool.

What's more, there are not one, nor two, but ten flying artillery shells. If you think about it, you can project hundreds of catties of black powder into the enemy camp or the enemy city. This power.

The remaining seventy or eighty guns next to them seem to be much slender. The gun mounts under the gun body and the two large wheels are more agile.

These are the Dengzhou Firearms Workshop, produced according to Cheng Sablang's design, specially used for land warfare.

The large wheels of these marine artillery are not much different from the wheels of the carriages commonly used in the Tang Dynasty, except that all the decorations have been removed.

As a result, together with the gun mount, the gun body and the tractor, the weight of the entire gun reached 2,300 catties.

The pulling artillery is two horses, pulling a car, which is also loaded with the ammunition and propellant needed by the artillery.

As a result, the mobility of the Datang Artillery was greatly improved in an instant. It can fully meet the requirement put forward by Cheng Saburo to make a shot and run away.

Far more than those short and dwarfed, they can only be moved to carriages, and the navy artillery transported by carriages is too much stronger.

But the problem is that the caliber of the navy's artillery is awesome, and its power is far higher than those of these land guns.

These land artillery have only two calibers, one is a three-inch gun, and the other is a four-inch gun.

The solid shells of the three-inch cannon weigh five jin, three 22, and four cents, while the four-inch cannon's shells weigh ten jin, ninety-eight, four cents, and six cents.

Datang made artillery with iron fans at the beginning. After all, Cheng Sanlang, a great inventor, was there, and it was too boring to make clay fans.

When the blacksmiths of the Han and Tang trading firms in the Tang Dynasty were engaged in large-scale castings in the early years, they found that the clay model castings can only be used once and then scrapped.

And after the clay fan is done, it has to wait for it to dry slowly, otherwise, bubbles will appear on the surface of the casting, or even inside.

After Cheng Sanlang heard the news, he immediately gave a work instruction, gave up the clay fan that he started, and used the clay fan to make a standard iron fan.

Then use this standard iron mold as the original version, and after making more iron molds, use iron molds to cast parts.

In this way, with the same scale of iron fan, the size of the castings made will naturally be almost negligible.

The most important thing is that iron fan, no matter how many times you use it, as long as you are careful, it will not be damaged, and it is very convenient to use.

In addition, after carefully applying the graphite layer in the iron fan, there is no need to worry about the casting and the iron fan being glued together.

And if you use a clay model, hehe... Every time you cast a cannon, you have to make a clay model, and after the clay model is made, you have to wait for it to dry out. If it is rainy, you can't do anything except beat the child.

In short, an iron fan, regardless of whether it is going to rain or the mother wants to get married, without delay, can cast four to five artillery barrels in one day.

Ten iron fans can produce 40 to 50 gun barrels per day, and the caliber, weight, and size of the gun barrels of these guns are almost exactly the same.

It can be considered that the standard parts were made unintentionally, and the artillery production of Datang also adopted this method.

This is also the reason why the Dengzhou Navy of the Tang Dynasty was able to transform so many gunboats at a speed that surpassed Britain and the United States.

"Is this the request given by the Emperor of the Tang Dynasty?"

In just over half a year, Yuan Gaisuwen, whose beard and hair were already covered with silver threads, lowered his head and looked at his subordinates who were obedient to the ground.

This is his study, the envoy Zhu Wen, who was quietly assigned to the Tang army camp by him.

After all, now Koguryo has been losing in a row, and all the places west of Yalushui have fallen behind the Tang Dynasty.

Duck green water and natural danger, which had been relied upon before, could not make waves at all under the indiscriminate bombardment of the Tang gunships.

When the Tang army established a firm foothold on the east bank of Yalushui, Yuangaisuwen already understood that Goguryeo had no hope of victory.

Originally, it was hoped that those cities west of Yalushui would use a deadly defense to kill the strength and morale of the Tang Dynasty.

Just like in the past, when dealing with the former Sui Dynasty, as long as it survives the winter, then Datang will definitely become another Central Plains Empire that failed to attack Goguryeo.

It's a pity that Tang's artillery, such a terrifying weapon that suddenly appeared, is simply invincible.

As long as it starts breathing gunpowder smoke and flames, whether it is the armored warriors of Goguryeo or the solid city walls, it will collapse and collapse under its repeated bombardment.

That's it, Yuan Gaisuwen felt that he could defend the fortresses east of Yalushui for a year and a half.

After only holding on for more than two months, UU reading www.uukanshu.com was pushed flat by Tang Jun, and he was flatly pushed out.

And the warriors of Goguryeo have no fighting spirit and can't even touch the enemy, how can they fight?

And the scene in Baifenkou City also made Yuangaisuwen feel more and more sad.

"Yes, the emperor of the Tang Dynasty, he has no intention of accepting the surrender of my Goguryeo. Now, I have no retreat in Goguryeo."

The messenger stood up and said towards Yuangaishu, whose eyes were dull. "Da Mo Li Zhi, let's go..."

"Go? Hehe..."
