Fifteen years have passed, and the situation on the mainland can be described as a sea of vicissitudes in the past 15 years. In 440 AD, the Huns again turned their attention to the Byzantine Empire and repeatedly infested the merchant markets on the north bank of the Danube. Attila accused the Byzantines of not fulfilling their treaty, and claimed that the bishop of Magus had desecrated the royal tombs of the Huns on the north bank of the Danube, threatening to attack Byzantium again. Attila led the Huns across the Danube, destroying the Illyria region (present-day western Balkans) and Thrace, including the provincial capital Femirakon. The Huns attacked as far as Magus, and while the Huns were negotiating with the Byzantines to surrender the bishop, the bishop fled and abandoned the city.

Theodosius II, after the capture of Carthage by the leader of the Vandals, Geseric, and the invasion of Armenia by the Sassanid Emperor Istegad II, decided to remove the fortifications along the Danube and redeploy his forces against Gaiseric and the powerful Sassanid Empire. This made it easier for Attila to attack the Balkans.

In 441 AD, the Huns captured the cities of Magus, Femirakon, Singidunum (present-day Belgrade), and Selman, until the following year, when Theodosius II brought back his troops from North Africa and issued new gold coins to pay for his military expenses, temporarily halting Attila's offensive. After this, he believed that he had enough strength to fight Attila and refused the Huns' request.

After his request was denied, Attila launched a major offensive along the Danube in 443 AD, capturing the military town of Latiara and besieging Nice (a city in present-day Serbia). In these two battles, the Huns used heavy equipment such as battering rams and siege engines for the first time. The Huns then swept across the Balkans again, capturing the major cities of Shırdika (present-day Sofia, Bulgaria), Philippopolis (present-day Plovdiv, Bulgaria), and Lyulebul (present-day city in Turkey), and finally to Constantinople, the capital of Byzantium.

Although the Huns wiped out the Roman defenders outside the city, they lacked siege equipment and could only besiege Constantinople in the face of the huge walls.

After a long siege, Theodosius II surrendered and ordered the royal envoy Anatorius to negotiate a peace treaty with Attila. Eventually, Theodosius II reached an agreement with Attila for a more severe treaty: Byzantium agreed to pay 6,000 Roman pounds (about 1,963 kilograms of gold) as punishment for breaking the treaty, and the annual tribute was tripled to 2,100 Roman pounds (about 687 kilograms of gold), and the ransom paid by each captured Roman was increased to 12 gold coins. These terms, while placing a heavier burden on the Byzantine Empire, temporarily satisfied the Huns' desire to retreat inland once again.

Around 445 AD, shortly after the Huns had withdrawn inland, Breda was killed by Attila. After killing Bleda, Attila became the sole ruler of the Huns and once again pointed the finger at the Byzantine Empire.

A series of man-made and natural disasters befell Constantinople after Attila led the Huns to withdraw: the great riots in the arena, the severe plague and famine of 445-447 AD, and the great earthquake that almost destroyed the great walls of Constantinople. In 447 A.D., Attila, who had consolidated himself as the sole leader of the Huns, waited for an opportunity to invade the province of Mercia. On the banks of the River Witt, a Gothic cavalry commander led a Roman army to resist, but was defeated by Attila. However, the losses of the Roman army were still modest, so Attila bypassed some of the major military towns and crossed the Balkans to the mouth of Thermopylae (present-day Greece). But when the Huns reached Constantinople again, they were helpless in the face of the rapidly rebuilt walls. Attila then put forward the conditions for the restoration of "peace": "the Byzantines must continue to fulfill their duty of tribute, and remove all the fortifications within the five-day ride south of the Danube". Since then, the negotiations have continued intermittently for about three years.

In 450 AD, Attila began to focus his attention on Western Europe and offered an alliance with the Western Roman Empire against the powerful Visigothic kingdom of Toulouse. Prior to this, Attila maintained a good relationship with the Western Roman Empire, especially with Aetius, who had become Grand Duke at the time, who had been exchanged as a hostage to the Huns as a child and had a close friendship with Attila. At that time, the successive victories of the Hun army over the Basques and Goths earned Attila the title of "Generalissimo" in Western Europe. King Gaiseric, the king of Vandal, in the shadow of his fear of the Visigoths, also helped to increase Attila's influence in Western Europe.

But in the Western Roman Empire, the then emperor Valentinian III and his sister Honoria took opposite views on Attila's proposals. In order to avoid a marriage contract with a court official, Honoria proposed to Attila in the spring of that year. After considering it, Attila accepted her offer, but offered to give half of the empire as a dowry. When Valentinian III learned of this, he asserted that he rejected the proposal and replied to Attila on the grounds that "the marriage proposal was not legal", and sent a message to the regent Empress Gara. At the suggestion of Plasitia, Honoria was exiled. However, Attila was not convinced, and sent an emissary to Ravenna to demand further explanations, preparing to attack the Western Roman Empire if a satisfactory answer could not be obtained.

In the same year, Emperor Theodosius II, who had ruled for 42 years, was killed by a fallen horse, and Marcian stopped paying tribute to the Huns, because after years of being ravaged by the Huns and other barbarians, there was little left of the Balkans, the economic lifeblood of the empire. At the same time, the Frankish kingdom ruled under Attila's rule, after the death of the king, his two sons clashed over the throne, and the eldest and second sons appealed to Attila and Aetius for help, respectively.

Attila's envoy to Ravenna did not receive a satisfactory answer, and coupled with the Franks' pleas for help, the situation on the continent at this time was treacherous, and war was imminent.

Upper Britannia, Lontinium (present-day London)

Since marrying the imported daughter-in-law of Germania, King Uther has been beaten a lot, although the Celtic is fierce in battle, but the huntress of the primeval forest of Germania is flexible and has a variety of tricks, anyway, he can't beat others. However, the two of them have been fighting for more than ten years, but they have been doing well.

Artoria was fostered in the original home of Aktor. But the handsome knight of fifteen years ago is now a pot-bellied lord. And the handsome young man of Spreus at the beginning was also won by an enthusiastic Celtic girl and started a family.

On this day, Artoria was practicing two-handed swordsmanship under the tutelage of Splius' wife, Kelia. The young Artoria had sun-dazzling blonde hair, a voice clearer and more melodious than a bard, and emerald blue eyes, and a clean and neat face that could easily enchant women. (It was originally a woman, and the realistic effect refers to the small fresh meat)

"Young master, why don't you practice the Roman one-handed sword like Spulius?" Kylia asked as she corrected Artoria's posture.

"Defense, not what I want!"

"Whew!" Every time the sword is swung with the sound of the wind.

"And ...... Why are you so good-looking~~~~~~"

"Poof~~~" Artoria's sword was crooked to Grandma's house in an instant.

"Oh, don't be so old~~~~ If this sword goes down, your whole body will be handed over to someone else~~~" Kelia pulled Artoria's body back.

"Drive!" A scout cavalry sped through the street not far away.

"Looking at the way he looks, it doesn't seem to be good news." Artoria put away her greatsword.

"Don't be Jute again......" Kelia frowned.

"And the situation on the continent is not very good right now, Prius...... I don't think I'm going back to Rome......" Kelia muttered quietly.

"Kylea, you are also concerned about the situation on the mainland?" Artoria looked at the female warrior in front of her, who was less than thirty in size, and felt a little strange.

"Of course, that guy from Sprius didn't brag to me about his family history, what ...... the squire of the nobles of the Eastern Empire" Kelia's complaint seemed to be full of showing off.

"Uh.................." Artoria was a little embarrassed, because the nobleman was herself, and Merlin had already told her about her background. But this kind of thing is always difficult to say, so she still carries the identity of the prince of King Uther, even if it is exposed in the future, it can only be said that it is the nobles of the Eastern Empire, and the pot of the ministers~~~~ There is no way.

At this time, Merlin was considered to have made a fortune, and he was resourceful and served as the dog-headed military advisor of King Uther, the oracle of the goddess Andist, and the mysterious druid priest.

"Dangdang~~~~" There was a knock on the door of Merlin's office.

"Come in." Letting go of what he was holding, Merlin turned his head to look at the door. 、

"Your letter, my lord." Entering the door was a Roman, apparently, a letter from the Eastern Empire.

"Thank you." Merlin rewarded the messenger with five dinars, and the messenger thanked him.

Seeing the messenger depart, Merlin unfolded the letter.

"My dear Milding, I am glad to hear that you have taken up a position of authority under Uther. This year marks the fifteenth year of Artoria's birth, and Sebatia and I are thinking about her every moment. But it backfired, and maybe I won't ever see my first child in my life. And now that the Eastern Empire is under the coercion of Attila's troops, Constantinople is also shocked three times a day. Letters from the Western Empire and the provinces asking for help also drifted on my desk like snowflakes, and His Majesty Marcian could no longer bear to read them. I thought about what you mentioned before, although Artoria now lives in Britain as a man, she should also have the ability to protect herself in these troubled times. If you and she are willing to respond to the call of the Western Empire and raise troops to support Aetius, then the Eastern Empire will provide you with support, which is a great bridge for the relationship between the Eastern and Western Empires, and also gives Artoria a chance to experience, I hope that my first child can at least die on the battlefield instead of being killed in the farm by the rebels. Forgive my nonsense, Mildin, I already hate myself for being powerless. I really miss the days when the two of us shot the Huns on the banks of the Danube. - Antemius (V)"

"I don't know how many copies you sent, but in the end this is only one copy, my young master." Looking at the code at the end of the letter, Merlin sighed. Each letter represents the life of a loyal warrior, but Antemius is still in contact with Merlin, which shows that he is genuinely concerned about his daughter.

"Let's talk to her." Merlin disguised himself and sneaked to Aktor's house. Saying that it is the Actor family, it is actually a pretense, Artoria has its own independent mansion, and Prius and Kelia often come here to visit and teach her martial arts, and Merlin himself often comes here to teach Artoria various cultural knowledge.

"Huh~~~It's all here~~~" Merlin pushed the door and found that the three of them were all in the yard.

"Master Merlin." Realizing her humble status, Kylia bowed anyway, though Split only nodded.

"Artoria, Spreus come along, this time it's a big deal." Merlin beckoned the two into the back room, but Kelia didn't follow up.

In the room, the three of them sat around a table.

"The lord has a letter from Constantinople." Merlin handed the letter from his bosom to Artoria, who read it quickly.

"Young master, you ......" Merlin looked at Artoria, waiting for her answer.

"Since this is the case, then I will respond to the call of the Western Empire and raise troops to serve the king." Artoria placed the letter on the candle and burned it.

"Young master, the opponent may be Attila, the invincible whip of God, the generalissimo and the god of war that the barbarians avoid. And the war on the continent is not comparable to the village brawls of Uther and them. Merlin nodded.

"My father made it clear in his letter, and I don't want to be hacked to death on the farm by the rebels." Artoria is young and vigorous, and to be honest, he has never seen much of the world, and he is a little newborn calf who is not afraid of tigers.

"I will follow you to the death, young master." Hearing that he was going to war, Spreus, the captain of the personal guard, naturally wanted to express his position.

"Since that's the case, then I'll go and prepare, and I'll communicate with the master again during this period." With that, Merlin stood up.

"Spreus, you and Kylia must train the young master strictly during this time. Also, I'll get a horse, and you'll teach her how to ride. "Merlin didn't say it explicitly, he could ride a horse, and if he lost a battle, he could at least run.

"I understand." Splitus naturally understood what Merlin meant, over the years, he has not helped Uther in the village brawls, what led people to pull the frame, was picked up by Uther with the young main guard to repair others, Uther was beaten and asked him to take the guards to help find a field, he naturally did a lot of these things, when it comes to combat experience, it is naturally a veteran.
