After taking Merlin's sister and brother-in-law to Hogwarts for a meal, Alan returned to the Black Lagoon.

Alan brought with him the heavily armed Death Knights, who were destined to be better equipped in the future, and who now only used normal weapons and armor to satisfy Alan's personal fetishes. Together, they made their way into the lake, to the cavern that surrounded the depths of the Black Lagoon at Hogwarts.

The natural textures on the walls of the massive cavern painted with demonic blood looked exactly like the last time Eren had seen it, and it had not been eroded by the years of magic.

Walking inside, the zombies in Muggle armor were no longer in a hurry to build the mage tower, except for the signs of being overlooked by negative energy due to the long-term activity of the undead here, there was silence here, and the Ravenclaw mage tower had disappeared from this cave.

Eren took the Death Knights to a tributary cave at random, ordered them to enter, and the magic tumbled, and the dirt splattered everywhere, forming a neat small mound of dirt next to it, and a huge pit appeared in this cave.

At Eren's command, the Death Knights lined up neatly in the pit, and then the dirt was sprinkled on them again, and the Death Knights who obeyed Eren's orders did not blink an eye, and just let the dirt bury them.

Above the dirt, Eren used his staff to meticulously imprint the ancient magic script on the ground, outlining the dirt where the Death Knights were buried, emitting a faint reddish-black glow. Eren had set up formations on the dirt that could absorb negative energy, so that he could ensure that the Death Knights had enough energy to sustain their bodies and not decay over the long years of waiting.

After doing all this, the wizard tried to sense the location of the Blood Oath, and found that Rowena Ravenclaw had completely obscured his position, and Alan estimated that the other party had not yet become a real false god, and had not yet mastered the method of keeping her face youthful, so she didn't want to see her at all this time.

Shrugging helplessly, Alan left the information that he had asked the other party to help take care of the Death Knight in the cave, and then stepped into the shadows and teleported back to Hogwarts Bonnie's office.

For Merlin, coming to Hogwarts certainly brought him a very new feeling, but when he saw Alan again in the vice-principal's office, he was very reluctant, he was now sent to the school of witchcraft and wizardry, which meant that he was about to be separated from his mentor, which made him a little sad and sad that he had already developed some dependence on his mentor, and he had experienced too many separations recently.

Even if Alan could not probe Merlin's thoughts, the reluctance written on Merlin's face made him understand what he was thinking and thinking at once. Alan used his hand to find the time turner hanging around his neck, and a small part of the pink sand in the last small gourd did not fall into the gourd below, which means that Eren can stay in this plane for a while.

"I'll find a hotel in Hogsmeade for a little while, and I'll find some materials to finish the oak wand I'm going to give you, and if you wish, I'll come here after Bonnie and your sister and brother-in-law teach you and your sister and brother-in-law how to read and write every day, and since I've become your mentor, I'll always have to teach you something myself." Seeing that he couldn't go back anytime anyway, Alan came up with the idea of really teaching his apprentice for a while, and he took responsibility.

"Mentor, I'll be on time!" Merlin was overjoyed when he heard that his mentor would stay for a while, and that he would teach himself to learn magic for a while.

The rest of the time was a rare peace after this transition, and Alan taught Merlin in his inn room in Hogsmeade every day, telling Merlin about some of his experiences and matters that need to be paid attention to in magic, hoping that Merlin would avoid some detours in the process of studying magic, and that he would be able to expand his horizons and increase his knowledge, so that he would not go down the wrong path of pure white or pure black wizards......

For little Merlin, the daily heavy schoolwork has made him very tired without attending classes at all, but he still insists on walking to Hogsmeade every day and learning from his mentor seriously, although Merlin has actually just memorized the alphabet now, let alone understand the esoteric theory of magic spells, but Alan still half-crammed his apprentice to memorize the oral knowledge as much as possible, and used a lot of practical demonstrations to make Merlin have a basic concept in his mind- The fact that he could not read and write and the demonic bloodline of the bottomless abyss made it difficult for Merlin to learn some of Eren's strong and inductive knowledge of being too organized, but it also made him appear to be very talented in his practical demonstrations and operations - especially in Transfiguration and prophecy, which surprised Allen as well.

In this way, little by little, bit by bit, drop by drop, Allen only developed a collecting habit like a philatelic by nature, and now he still has the appearance of a mentor and an apprentice. It's just that the time to get together is always short, and there is not much pink quicksand left in the hourglass of the time turner, and the time of separation is coming.

On this day, when Merlin left Hogsmeade and returned to Hogwarts, Alan let his shadow raven carry some parchment and fly out of the window, and then he checked out of the inn, and then went directly to Bonnie's headmaster's room, and after a while of greetings, Alan explained the purpose of his trip: "Bonnie, you can also paint a portrait of yourself and Merlin, and put it in the room where you hide something in the Room of Requirement, and I will add it to Helga's painting later." ”

"Is the time?" Bonnie looked at Alan's face as if it had not been soaked in any time, and remembered the reason her mentor told her, she realized that the other party was about to leave this era, which was reasonable, and Bonnie was not surprised, but to her surprise, Allen's final request made her understand, compared to her original inference, Alan was obviously more emotional than he looked, " I would, but I'd better put it behind the picture of the silver bowl full of fruit in front of the kitchen, and I'll put it on the back of the frame. ”

"Hufflepuffs always knew how to hide – how to protect themselves. Alan nodded and realized that he had just taken it for granted, the room where things were hidden in the Room of Requirement in his time had been the result of thousands of years of continuous efforts by students and professors to achieve that scale, and now for Hogwarts, which was founded less than a hundred years ago, it was obvious that what was put in at this time was not so easy to avoid being discovered by others.

Finally, he gave Bonnie a final hug as a goodbye to herself, and after letting go, Alan shook his hand at her again, and stepped straight into the shadows to the place where he and Ravenclaw had camped in the Black Lagoon.

This time, Alan didn't need anyone to see him off, he didn't alarm the others, but asked the Shadow Raven to leave a farewell letter to Merlin, who was still returning to Hogwarts, with some goodbye words and some advice, as well as some of his own magical experiences and records.

Then, as the last pink crystal sand in the transparent gourd slid down, Allen's figure disappeared from England in 1066 without a trace.

By this time, near London, the remnants of the Anglo-Saxon English nobility had previously put up several small resistances, all of which had ended in failure, and the surviving British lords began to fight among themselves. The aristocracy, led by Earl Edwin and Morka, the last male descendants of the Wessex dynasty, was elected as the new King of England before Edgar II, who had not yet had time to be crowned, went out of the city to show obedience to William, and in any case, Harold, the Anglo-Saxon King of England, who had recently defeated the last Viking invasion, was killed, and William was crowned the third King of England that year at Westminster Abbey on Christmas.

William succeeded in conquering England and was crowned king with an iron fist, and he distributed the land that had belonged to Harold and the Anglo-Saxon nobility in the south of England to the nobles who had contributed to the battle, strengthening the royal power and reducing the power of the nobility to a limited extent, trampling under the feet all the Anglo-Saxon lords who sought to become independent and self-governing.

At this time, like his Viking ancestors, the new King of England, William I, made a turn that could be called magnificent. He didn't care to sit on the throne of London and didn't bring the crown of England back to France, less than half a month later, a rebellion broke out on French soil, and he returned to Normandy by ship with his army, and the most interesting thing is that William set foot on the island of England once in his life, and then he, as the nominal king of England, never came to England again.

In 1085 and 1086, the bastard king sent a survey of the actual situation and economic power of the land of the nobility and yeoman farmers throughout England, and issued a survey of land taxes known as the Last Judgment, according to which Merlin's hometown, Crawhurst, was already a white land that had never been rebuilt.

A year later, in 1087, Merlin, who had already graduated from Hogwarts Slytherin, finally escaped the defenses of William's captive wizards in July of that year in France to complete his revenge by stabbing William with the dagger called the Pink Bunny that Alan had given him, and using the power of the curse to make the wound appear as "the bastard son of the leatherman's daughter died from the dagger Pink Bunny" Two months later, William I, who had not been able to lift the curse and heal the wounds of the wizards around him, died at the abbey of Saint-Gwens in Rouen, with his third son, Wilhelm II, by his side, and the Normans were so ashamed of this manner of death that the Normans had to announce that their king had died in a horse accident.

As soon as William died, he was transported back and buried in the Abbey of Saint-Etienne in Caen, Normandy. He grew fat in his later years, and when people tried to stuff him into the coffin during his burial, his body was swollen by the power of Merlin's curse, filling the entire church with a foul smell - if the future Hogwarts former Slytherin Quidditch captain Marcus Flint were here, he would have recognized the resemblance of this smell to the super-powerful dung egg.

In the end, when William arrived at the cemetery and was about to be buried in the grave, the accident happened again, and Mordred, the balding former pot head knight and now the Baron of Normandy, suddenly jumped out like crazy and claimed that the land of the cemetery belonged to him, and punched down the priest Randolph who came to pacify him? Frémontbard, and then demanded justice in the presence of the Brittany and French nobles who had come to the funeral, as well as the native Norman nobles, and the body of his father, William I, was buried after Wilhelm II had paid sixty shillings in anger.

As the son of William I, Wilhelm II, known as the red-faced William, was not only a combative soldier, but also a ruthless ruler who ruled places loved only by a few; In the Anglo-Saxon chronology, he was "hated by all the people." And as a gay king who never married and never had an illegitimate child, he was even more annoyed that Mordred had beaten his favorite Randolph Flemontbard, which led to the destruction of his own family, Baron Mordred, who was controlled by Merlin's Imperius Charm.

After completing his revenge, Merlin, who had no target for hatred, finally put the target back on magic, but because he had learned through investigation that Vice Headmaster Bonnie had known his mentor before the establishment of Hogwarts, and the one-sided information that he had heard from Eren before, Merlin mistakenly thought that his mentor Alan was from the past.

This eventually led Merlin, who did not have a time turner, to venture directly into the use of the Hour Reversal Charm to try to follow in the footsteps of his mentor after founding the Sir Merlin, which was committed to promoting the legal protection of Muggles like his sister Judith and brother-in-law Toffei, and defending their rights and interests. Over the course of a long time, the Order of Merlin, which he founded, had transformed from an organization focused on Muggle rights to an award society that usually recognized great magical achievements.

Merlin, who was trapped in that era and did not dare to move, eventually became King Arthur's best friend and mentor to Arthur Pendragon, and often used prophecy and other magic spells such as Allen's sea control technique to separate the waters of the Black Lake during the Goblet of Fire tournament to help King Arthur and help him establish the Knights of the Round Table. Eventually, Merlin guided Arthur to obtain the Sword of Kings and rule England at the time.

As the wizarding world progressed under Hogwarts and the subsequent schools of witchcraft and wizardry, and wizarding society developed in the 12th century, when Hogwarts graduate Merlin and Arthurian Merlin were finally confirmed to be the same person by wizards, Alan Harris's secret apprentice gained the prestige he deserved in the wizarding and Muggle worlds.
