Eric Lanster looked at the gloomy castle in front of him and became a little alert to Professor Sean, and even regretted coming to visit.

He has lived in a sinister environment since he was a child, isolated and helpless, so he is cautious by nature. In contrast, the other people seem a little careless, especially Slater, who suddenly showed an excited look when he saw the castle in front of him.

"Cool! What a spectacular castle."

The word cool is a fashionable word that has only become popular recently. Young people often use it to express their inner excitement, but Emily doesn't think so. She can see more castles and other things.

Several people walked through the open space outside the castle and walked into the gate of the wall. In the wall was an open square. In ancient times, knights could prepare weapons and horses here as a preparation area for rushing outwards.

The castle was desolate and very quiet. When the group walked over, they found that the castle was not as dilapidated as it looked. The schoolyard of the castle was cleaned up and there was no weed. When they walked into the castle, the decoration inside was also very home-friendly, not as dark as it looked, clean and tidy.

"Professor Sean, do you live alone?" Melisson Sheila suddenly asked in the lobby on the first floor of the castle.

"Yes, I like being alone."

"Wouldn't that be very lonely?"

“For writing, sometimes loneliness is also a necessary condition.”

"How do you maintain such a big castle alone?" Eric asked out the doubts in his heart.

"Haha, I won't have much impact on the hygiene of the castle, so I don't need much maintenance."

This made several people believe it. In their opinion, if a thing is not touched, it will naturally not break and naturally there will be no need to maintain it.

Only Emily vaguely felt something was wrong, the castle or something seemed to require a lot of people to take care of.

But she didn't ask.

The group walked through the dark corridor, stepped on the spiraling stairs, and followed the tower to the second floor.

Sean, who was walking in front, introduced from time to time, "This is a banquet hall, we can eat here at night. I usually eat alone. The banquet hall is a bit too big for me, but with you, it should be different."

"This is my study. I have transported all the books in my apartment. It can be used to pass the time and also be a good way to maintain my reading habits."

“That staircase leads to the watchtower on the top floor, which is the highest point of the castle and is very suitable for viewing when the weather is clear.”

"Oh by the way, be careful of the stairs, this castle needs repair in many places."

Sean said and kicked a slightly loose stone brick.

"Professor Sean, you said you were bringing us here to show some 'ancient secrets' and 'mysterious treasures'." Sam reminded.

Sean smiled, "I almost forgot if you don't say it, come on, right here."

He brought a few students to another hall, which was originally a warehouse, but has now been transformed into a showroom for use.

It was filled with the spoils he brought back from Nord, and lit the torches, and the flames illuminated the showroom.

Gold utensils, gold withered sculptures, luxurious jewelry, weapons, armor, and some souvenirs brought back by Sean from Nord are almost the same as a private museum.

Several students were immediately stunned by what was in front of them.

Sam Dante ran to a piece of armor, "Oh my God, this is the armor passed down from the era of Arturus. This style, this shape, and this noble family emblem, this is the armor of the North Knight!?"

Several classmates were a little surprised. Sam Dent is quite knowledgeable.

Sean nodded in praise, "Yes, this is the treasure I brought from the City of Gods. It is likely from the time of Arturis and it is preserved quite well."

Merryson asked differently: "You really discovered the City of Gods? But wasn't that fictionalized by you?"

"Haha, not quite, I did find a lost city on the islands of the North Sea, but perhaps not the residence of the gods, and I have a more credible speculation about this.

Perhaps it was left behind by human civilization in ancient times. According to my observation and research, the world's climate will change over the long history. Perhaps tens of thousands of years ago, there were not as cold as it is now, and there were still humans living there. Perhaps it was the ruins of the city of that era.

The ancient Nords regarded it as a miracle, as a treasure land for the preservation of their spoils, and later gradually became forgotten. I was lucky enough to find it and brought out some treasures."

These words made several people fascinated.

But Eric turned his eyes to a bolt-moving rifle: "Is this gun the weapon you use?"

"Yes, this is a bolt-action rifle, the latest weapon developed by the Sword Castle Arsenal. The Kingdom Army has not had time to equip it yet. This was given to me by Captain Edward. As a gift to me to help him escape the pursuit of monsters, it is a very powerful weapon, but I can't use it now."

Emily walked to the bear fur coat, and Sean made a wooden model and put it on it, which looked very eye-catching.

"Is this bear skin worn?"

"Yes, the ice fields in the north of Nord are extremely cold. Only by wearing such clothes can you keep from being frozen to death."

Sean introduced his collection to several people with a lot of knowledge, and finally opened another box filled with ancient gold coins.

"These are all part of the treasure, the gold coins of ancient Brighton." Sean said, taking out five and throwing them to the five, "Take it, just treat it as a souvenir."

"How can you be so embarrassed..." Eric said uneasy.

Scott bounced excitedly and caught it, "Thank you, Professor, this thing is so cool."

The five people visited for a while and felt that this trip was not in vain, but Emily was still thinking about Sean's original promise.

"By the way, cousin, what about the 'taboo knowledge' you mentioned? What is that?"

"Cousin? Do you know each other?" Only then did the few people react.

"Yes, I am Emily's cousin. As for the knowledge of taboos - come with me." Sean took a few people out of the showroom and came to the study. He took out his new book manuscript.

"Look, this is my new book, and I haven't finished writing it yet."

"That's great!" Sam Denter looked through excitedly, but Emily was a little surprised. "This is the knowledge of taboos you mentioned? But I thought..."

"Why? You don't think I will show them magic, right? Hahaha, what do you think, magic does not exist in this world, but don't underestimate this manuscript. Many of the contents in it are very sensitive cutting-edge technology. Although it is just an idea in the novel, it can be realized in theory. Once created, it will become an invention that changes the world. It may be used in war and bring destruction and death, so it can also be called taboo knowledge, right?"

Several people were speechless about Sean's far-fetched explanation, especially Emily, who didn't know what expectations she came with, and was very disappointed with what Sean said.
