So Urban was authorized by the new Sultan, and he spent the autumn supervising the construction of the unprecedented cannon. Pen | fun | pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

Unlike the dying Byzantium, the thriving Ottoman Empire provided the genius gunsmith with all the materials he needed, and it took several months to finally complete it.

When the mold is shattered, what appears in front of everyone is a "terrifying and extraordinary monster" - the Urban Cannon.

At 5.18 meters long, it weighed 17 tons, with a barrel 20 centimeters thick to withstand the tremendous impact of the cannon, and a caliber of 76.2 centimeters, enough to accommodate an adult, and a granite shell weighing 680 kilograms, making it the most powerful firearm of its time.

This big killer was successfully transported outside Constantinople, and the foundry in Urban began mass production of the cannon, and a few months later, all the Orban cannons were in place, and for the first time in history, the artillery coordinated salvo was officially opened!

At that time, the battlefield of Constantinople was probably the most intuitive and shocking place in the history of warfare, and when the salvo began, the earth was turned upside down, the earth shook, and countless granite shells larger than people suddenly appeared in the sky over Constantinople.

The Europeans at that time had never been taught such a situation.

The stone bullet emitted a deadly scream, smashing the huge stone wall of Constantinople into pieces in an instant, falling apart, and the defenders were so frightened and overwhelmed that they couldn't react for a while, and they scurried for cover.

Some of the heavy shells even pierced through the city walls for a mile or so, destroying residential buildings and buildings of all kinds, and a strong tremor could be felt within a two-mile radius, even of warships anchored in the harbor.

It was more of an apocalyptic sign than a war, and helpless citizens could only gather in churches, hoping in vain for God's deliverance.

After the collapse of the walls of Constantinople, which the Byzantines regarded as their pride, the soldiers were eager to have Urban torn to pieces, but in any way could not change the fact that Constantinople had fallen.

After that, Europeans realized that traditional fortress technology was outdated, siege tactics were changed, and a new page in the world's military history was gradually opened.

It can be said that if he gets Urban, Zheng Fei will get the best cannon casting technology in this era, and the journey will be much smoother.

......

In a blink of an eye, a few days passed.

On this morning, the air was exceptionally fresh, and the fleet was driving along the coastline, and the evergreen sclerophyll forest on the shore was faintly visible, adding a rare touch of green to the blue picture of the voyage.

The wind was light, the speed of the march was slow, and the sailors sat on the deck, and the boring voyage of the days made them less interested, and sang a slightly sad song:

Our home is at sea

We wander and don't know where we're going next

We follow in the footsteps of the captain and set sail, and he can take us to make a fortune

The bad news is that payday is still far away

......

Zheng Fei understands that a boring life is easy to make sailors pessimistic, if it was in the past, he could let this group of guys play hot air balloons or something, but now it can't, because ......

He sat under the big longitudinal sail in the wind, fiddling with the sextant of the navigation artifact in front of him, which had been improved countless times by the engineers, and was already relatively accurate.

According to the current latitude and longitude, the position of the fleet is near Crete on the eastern side of the Mediterranean, north to Athens, Greece, and then northeast to Constantinople...... Well, it's time to call it Istanbul.

To get to Romania by sea, you have to enter the Black Sea, and there is only one strait between the Black Sea and the Mediterranean, and that is the Turkish Strait, known as the "throat of the world".

Istanbul, the capital of the Ottoman Empire, was built right next to the Turkish Strait, and if you want to go over, you will definitely appear in the sight of the "West Asian barbarians", and the garrison force is immeasurable.

You must know that in this era, the military power of the Ottoman Empire can be called the first in the world, and even overshadowed the Ming Empire, which was gradually declining.

Of course, the Ottomans did not know this, and they were under the impression that the Ming Empire was still the legendary Celestial Empire, with a strong army and a rich economy.

If they knew the real situation, they might have pointed the spearhead of attack to the east, and the land described in "The Travels of Marco Polo" and countless predecessors is really tempting.

Therefore, in the face of such a powerful opponent, it must not be high-profile, even if it is a character like Zheng Fei, it must be restrained and avoid head-on conflicts.

He put away the sextant and looked around, and there were more than a dozen guns on the side of each ship, and the black hole pointed at the sea, beware of possible pirates.

After thinking for a long time, his brow gradually frowned.

"Santiago, come here!" he shouted.

Santiago was teasing Vivien with a goblet and flirtatious, and when he heard his call, he pouted and pinched Vivian's ass, and quickly ran over, Vivien chuckled and stroked her hair, and went back to the house.

"What's the matter, man, it's not going to be a nut smash, right?"

Zheng Fei snatched his goblet and took a sip, his face solemn and sad.

"Go and inform all the ships, unload all the guns, pack them with the shells, and hide them in the most secluded part of the cabin. ”

Santiago scratched his head and snatched the glass back, pouring the last few drops of wine into his mouth and smacking.

"But what if we run into pirates?"

"Rest assured, such a large caravan pirate would not dare to rob it. ”

Santiago had never liked to ask and think too much, and he found it tiring.

After chatting with Zheng Fei for a few words, he did what he was told and informed each ship in turn.

Not only artillery, but also the epoch-making rifled guns and hot air balloons were also stored and hidden under the bed and other places to avoid being discovered by the war-hungry Ottomans.

By the end of the two hours, the deck had been cleaned, not even a drop of gunpowder remained, and to the fishermen nearby, it seemed to the fishermen that it was a normal caravan, but a little larger.

"Oh, Cyril, you see, it's a rich man's fleet again. ”

"Look in this direction, you're going to the Fallen Capital, right?"

Since the fall of Constantinople, it has been known as the capital of the fall by people within a radius of several hundred miles.

"Alas, I don't know what kind of business they do, I hope luck will be better, so that it won't be like the caravan last time, and there will be no shells left by the barbarians. ”

At this point, the fleet was fully in the Ottoman-controlled seas, and in a day at most, it would be possible to reach the Turkish Straits.

Zheng Fei climbed the watchtower and looked at the sea in the distance with the help of a telescope.

A fleet caught his eye, it was an Ottoman patrol. (To be continued.) )
