Constantinople, formerly known as Byzantium, is located at the eastern tip of the Balkan Peninsula, near the Bosphorus, the gateway to the Black Sea, and is a strategic position of great importance when Europe and Asia are at the heart of the traffic. As the capital of the Eastern Roman Empire (Byzantine Empire), it became the political, economic, and cultural center of the eastern Mediterranean. Constantine I, a soldier by military force, was proclaimed emperor in Britain in 306 and decided to build a new capital in the eastern part of the empire to defend the borders of the Danube and Euphrates, which were threatened by the Goths and Persians. In the eastern part of the Roman Empire, previous emperors had already established several imperial capitals, such as Emperor Diocletian, who had his palace in Nicomedia (present-day Izmit, Turkey) on the Asian side of the Bosphorus. In order to choose a site for the new capital, Constantine I visited Troy, Jerusalem, Saldica (Sofia), Thessalonica (Thessaloniki), and Nicomedia, but finally chose Byzantium, which was not well known at the time, as the site of the new capital.

Byzantium is located on the western shore of the Bosphorus, a narrow strait that separates Southeast Europe from Asia. The city itself sits on a small hill bordered by the Sea of Marmara to the south, the Golden Horn to the north, the entrance to the Hellespont (Dardanelles) to the east, and the Thracian plain to the west. The entire city is like a fortress made in heaven, easy to defend and difficult to attack. Not only that, Byzantium was also the intersection of the Egnumdia Avenue, an important military avenue of the Roman Empire, and the military highway in Asia Minor, which was the only way to Asia and the only way from the Black Sea to the Aegean Sea.

In addition, the Golden Horn Bay in the north of the city is a natural harbour with a total length of about 10 kilometers, a main channel of about 460 meters wide, and a number of branch waterways for boats to berth. Since ancient times, it has been a place where merchant ships from all over the world gathered, bringing wealth to the local population, hence the name "Golden Horn" (in Greek mythology, the ram's horn is a symbol of harvest and wealth). In the future, Xindu can rely on the terrain of facing mountains and water on both sides to defend against attacks from all sides, and can also take advantage of convenient water and land transportation to develop business. In 324, Constantine issued an order to build a new capital and appointed important ministers to begin preparations for the construction works. In order to complete the construction of the new capital in the shortest possible time, he also ordered the construction of a vocational school to train a large number of various architectural talents. Constantine also personally surveyed and demarcated the city's boundaries. After five years of meticulous construction, the ancient Byzantine city was gone, and a new capital city of magnificence and magnificence appeared on the shores of the Bosphorus. On Monday, May 11, 330, Emperor Constantine declared his capital in his new capital and gave it the official name "Nova Roma".

Under this natural and man-made impregnable defense, even with the strong military strength of Britain, it will be difficult to capture it for a while.

"Collect the troops. Seeing that this is not known to be the first time that the attack is still fruitless, Lia sighed helplessly, the non-stop attack for several days has made Britain's losses very serious, even surpassing the losses caused by the head-on collision with Eastern Rome, but it has no effect, which really makes Lia helpless.

In fact, Liya didn't think of other methods, after the first strong attack failed, Liya also tried a very classical tactic, digging a tunnel. But after a few days, for some reason, all the tunnels were discovered by the Eastern Romans, and all the people in the tunnels were buried alive in the tunnels.

As time passed, there was no way for Leah to start a strong attack, groups of imperial soldiers raised the ladder to charge, but they were repulsed again and again, Leah had to sigh that Eastern Rome was worthy of being the previous Europa overlord, even if it was forced into a desperate situation, it was still impressive.

Seeing that several days have passed, but there is still no progress, how can this keep Leah from being in a hurry?

"Don't worry, king, now that the whole of Europe is under our control, even the lonely city of Constantinople will not be able to make any waves, as long as it remains like this until the food in the city is exhausted, it will naturally not be breached. Seeing that Leah's face was not very good-looking, Lancelot opened his mouth to comfort her.

"It's true, but it's a little eager. Leah was stunned for a moment, then whispered.

Looking up at the sky, I haven't been back for a long time, I wonder if they miss me?

Thinking of this, the corners of Liya's mouth unconsciously showed a hint of a smile.

"It's not impossible to end it sooner, it's just that" Lia looked at the sword of victory of the oath wrapped in the wind in her hand, and sighed helplessly, not to mention whether the magic can support it, it is already something that only heroic spirits can do, can she bear the 'crystallization of human prayers for miracles' with her own human body?

Looking back at Constantinople in the distance, Leah's mind flew somewhere, it was rare to be so leisurely on the battlefield.

Leah, who was wandering in the world, was suddenly awakened by a burst of nerve tingling, which was a danger alarm transmitted by intuition, and then heard the exclamations of Kai and Lancelot and others, and had no time to think about anything, the danger from intuition made Leah subconsciously turn on the absolute defense of 'Avalon'.

In an instant, Lia's surroundings were surrounded by a fairyland-like world, and the black shadow that was speeding at a speed that was impossible to see with the naked eye was completely blocked out.

"Didn't that man say that King Arthur could definitely be killed when she was defenseless, and why would it be useless?" asked Justinian the Great on the city wall with a deep disappointment on his face, and asked the people around him in a loud voice.

"Your Majesty, I don't know, you have personally tested the power of that weapon, and it can be said that it is more powerful than all known things, and I don't know why this happened. The official on the side said with sincere fear.

"But even though she is more powerful than all that is known, and is still of no use even to the unsuspecting King Arthur, is she really so powerful?" said Justinian, reluctantly.

"This feeling" Liya came back to her senses and looked blankly at the city wall in the distance, and something that suddenly appeared at some point, others may be unfamiliar, but for Liya it is a look that will never be forgotten.

Because, that is the 'sinner' who took Gwynaville away from her forever.

"Is that so? I see, did it all start here? is it all because of this?" Leah closed her eyes and murmured softly, she remembered Gwyna Veril's bright smile at all times and places, and the sadness hidden behind it, and her heart ached as if it had been stabbed by a sharp stab.

I don't understand why the Eastern Romans would give France such a powerful weapon, but it's all unimportant, isn't it?

What mercy, what mercy, it's too hypocritical, she's a king, isn't she used to killing? The only trace of hesitation in her heart vanished.

For, the girl who loved her when she was dying, the girl who closed her eyes in her arms with regret.

"Hope?" said Lia, standing in the distance of Constantinople, her armor fluttering violently in the wind, muttering softly. Then he closed his eyes and resounded in his mind with Gwynaville's appearance and voice echoing again, and a smile appeared on the corner of his mouth, "Your hope, I feel it, very powerful, Gwynaville." ”

When I opened my eyes again, there was no other superfluous emotion in my eyes, just full of determination and confidence.

"What is she going to do, King?" asked Gawain as he saw Leah walking in the direction of Constantinople, looking at Lancelot in bewilderment.

"I don't know, but because I won't. Lancelot also said uncertainly.

Alone, when she came to a short distance from Constantinople, Leah stopped, looked up at Constantinople, and there was not the slightest emotion in her eyes, but she drew a gorgeous and simple golden sword from the void behind her, and raised it high above her head, as if preparing something.

"How is it possible, even a king can't use a human body to urge such a holy sword, right?" exclaimed Lancelot in horror.

And then the facts broke the knight's cognition,

‘EX’

The true name of the Noble Phantasm was called out loudly, and the golden sword seemed to respond, the blade emitting a dazzling golden light. EX, the ancient Celtic word for broken steel, but here, it will be to cut off everything in the world.

‘calibur‘

The real name was completely liberated, and the golden brilliance of the sword body became bigger and bigger, gradually enveloping Liya's whole person in a golden light.

Liya clenched the holy sword in her hand, it was the strongest holy sword that gathered the light of the stars, and it was at the peak of all the holy swords.

'---- Oath Sword of Victory----

As the literal meaning is, it is a light, a torrent of light, a sword of light, not a man-made weapon, but a god-made weapon forged by the planet, and people crystallize inside the planet with the idea of 'want to be like this', and are refined into the 'strongest fantasy (Last. Fantansy)‘.

This sacred sword converts the owner's magic into 'light', which is then contracted and accelerated to increase its momentum, making it possible to perform god-level magic. It is the "ultimate slash" that cuts off all the objects through which the "fault" formed by the light passes. Its sheer magic imbues the parts beyond the tip with heat, and as a result, it resembles a wave of light that sweeps across the ground. It can be said to be a directional energy weapon.

So, this torrent of light struck Constantinople with the aura of destruction that wiped out all things.

No one doubts the outcome, and under the impact of this miraculous flood of light, everyone is convinced that nothing will survive, and everything is already doomed.
