Italian architects were a fairly advanced group of people in this era, with the exception of China. In the future, the Safavid Empire (in Persia) and other countries would hire Italians to help them repair their walls.

Now, however, the Chinese are coming.

"Boom wall! See, that's it! There's the key point, and if you blow him up, the whole wall will be unstable! Small artillery suppressed the head of the city, and big artillery blew up his corner! ”

There are quite a few artillery specialties in the army. Because there is no professional military academy, it has no choice but to carry out irregular model classes for veterans and teaching for technical arms such as army artillery and naval artillery. Veterans teach experience, teach mathematics, especially parabola, architecture, etc., and never lose it.

The veterans soon discovered the weakness of the castle built by the Venetians. Every wall has its weaknesses and strengths. If you focus on the wall, it may have some effect in the early stage, but it will be very difficult to completely smash it. The veterans all went back to find Qiaojin.

Looking at this sturdy fortress, Li Anshi suddenly asked his second son Li Zhidian: "Is this the first time that the dynasty has attacked a sturdy stone castle?" ”

There is a strict distinction between castles, fortresses, and cities. Unlike the ancient Chinese mixed ones, Western Europe has a strict distinction between them. Cities are places where merchants, petty citizens, and workers exist. They have nothing to do with the countryside in the countryside. The castle was a fiefdom of the aristocracy, combining military and agriculture as an economy of its own. Fortresses, like the Karaim fortresses, were completely insulated from the economy and were simply intended to control strategically important places.

Like Qin Cang's bombardment of the stone walls of Kyiv, it is just hitting a city. The city's resistance depended heavily on manpower, otherwise the massive walls would have been a basket. Castles are different. The castle is small, and all kinds of defense equipment are gathered, which is the first time in the dynasty.

"Write it down, write it down! I want to leave Li Anshi's name on Wenyuan Pavilion! Li Anshi said excitedly!

The eldest son said unrelentingly: "Dad, there must be you on the Lingyan Pavilion." What do you think Wenyuan Pavilion ......"

"Fuck your uncle! Unfilial son! It's just for daddy, right? Li Anshi was furious and continued to kick his eldest son's ass. The eldest is always against him, and the second is very literate.

.......

"Are our castles ready?" Livar, the governor of Poros, asked in shock.

"Ready." The attendant hastened to comfort his master.

Livar wasn't convinced yet. He hurried out of the house and went to patrol the city.

There is no problem with the moat, it is very dirty, and the river is full of feces and urine, and all kinds of garbage; The Venetians had taken refuge in the atrium; Upstairs, a fighting bucket has been built (a wooden house sticking out of the wall, which is equivalent to another layer of protection, playing riding and chopping, especially when attacking Zenda, you must know what the structure is); Ballistas and crossbows were also placed at the head of the city; On the watchtower sat two "black crows" (at that time, the sentries were called black crows. And the sentry's salary is only one-fifth, which is considered to be mixed food).

Walking to the top of the city, Livar tried it himself, and the battlements were strong, and the quiver barrels were full of arrows. The drawbridge was pulled up, and the gates were lowered. The gate is made of fine iron, and it is generally impossible to open it.

Leather and lead plates have also been placed on the watchtowers and floors.

"So where am I worried?" Livar touched his chest, not knowing what he was worried about.

Suddenly, the attendant flattered and said, "Perhaps...... We should plug the toilets. ”

Lavatory! To the restroom!

Livar suddenly thought of the toilet as if he had come to his senses.

The castle is all about protection. For the sake of simplicity, the toilets are deliberately opened at the wall and can be pulled into the moat at any time. This is also the reason why urinal toilets are so popular. Damn, who can stand running from one end of the castle to the other end of the castle to go to the toilet at night?

And there is a case called classic. In 1204, the Château de Carile-sur-Seine was breached by drilling through a hole in the latrine. Obviously, modern people can't understand how they got through the toilet holes that were several meters long. But that feeling of being covered in and urine is unbearable for ordinary people.

"That's right! Plug the toilet! Something to pull on the city walls! "Livar hurry up!" It's a loophole, you can find it in time, and that's good! You'll be rewarded with a silver coin! ”

The toilet was blocked in a panic with dirt bags. And then what?

Another squire has an idea.

"Will anyone be able to climb up to the place where the tower is built at the head of the city? Why don't we hang iron nail strings on the fulcrum used by the scaffolding to prevent them from climbing. ”

Scaffolding was a necessity for the construction of city walls. The tower was built higher and higher, and the scaffolding set up a fulcrum on the tower to pull things up. In fact, it is a crane-like organization. At this time, a row of wooden poles sticking out of the wall will be left at the height of the wall. So this has also become the support point for the construction of the building bucket.

However, at this time, the siege tower is still being built, and the ladder is actually very few or even useless.

"Yes! Just go! Look, a silver coin! ”

The attendants froze. it's too hard, right? ......

Besides, who is stupid to hang iron nail strings on those woods! If you accidentally fall down, it's a corpse! It's all wrapped, so you have to lie on it!

Livar was still flustered, and it wasn't until he stood on the tower, looking into the distance, that he understood why he was panicking.

The large black hole with the size of the cannon made Levar finally recall the tragic situation of the bombardment of the port just now!

"End...... It's over......" Livar didn't breathe evenly, and passed out directly.

They weren't prepared for a melee siege at all.......

The artillery positions on this side have already begun.

Because the preparations in the city were in a hurry, there were no trebuchets or other equipment to make counterattacks, so the large and small artillery simply approached and bombed!

The Spartan company was out of business. They crouched outside the artillery positions, alert for a counterattack in the city. And the artillerymen started a new tutorial with great interest.

"Do you know how to use a ruler?"

"Look at it from this angle!"

......

The attendants stood on the city wall and watched as the enemy's artillery shot more and more accurately! The more you bombard the city, the more it shakes!

The castle tower under his feet is already unstable! Every time it goes down, it can have an accident!

Two days later, with one scream after another, the two city walls directly opposite ...... It...... Collapsed........

The cheering soldiers of the wing carried the big shield in a row of ten people, and fifty people quickly surrounded it in a row! They must prove to Andrew Lee and the Privy Council that they are the best mountain and siege infantry in the country!

Otherwise, it would be too humiliating to be subsumed under the border army!
