“…… Why did it suddenly fail? Xia Di touched his chin, "If they have an immune constitution or a magic defense prop, they won't be able to hit it in the first place." Could it be...... Anti-overlay? ”

Thinking of the reaction of one of the guards just now, Xia Di had such suspicions.

The so-called anti-coverage phenomenon refers to the situation in which an object that has already been hit by a certain kind of magic is attacked again by a magic with a similar effect, and an immune response is generated.

Through observation, the two guards just heard their last question, and then they became wrong, that is...... The caster should have cast a spell on them, such as silence or brainwashing, so that he could not say the answer.

Generally speaking, even if it is the same type of magic, if you want to produce the anti-coverage phenomenon, there are conditions, that is, the first spell to be cast must be higher than the level of the spell cast later, and your own hypnotic magic is high-level magic, then the magic in them is at least the quasi-forbidden spell level.

What kind of magic can achieve this effect?

Xia Di hugged his shoulders and had a flash of inspiration: Could it be that it was controlled by sanity?

Mental manipulation is also hypnotic magic, belonging to the forbidden spell level, which can manipulate people's consciousness on a large scale, or tamper with people's memories, judging from the reaction of the squinting guard, it should be the latter, he probably has more information, so he was forced to modify all the memories about the renovation, otherwise his hypnotic magic would not be invalid.

Having said that, there are only a handful of people who can use forbidden spell-level magic even in the court, and according to Xia Di's judgment, the only people who can use this kind of magic on a large scale are probably only Merlin or a few chiefs of the palace mage group [Goddess of the Lake].

But...... Why would they do that? Is it to hide something?

Xia Di felt that he couldn't guess the answer, so he had to continue to investigate.

"What's next?"

Xia Di glanced out the window.

Suddenly stunned,

Under the bright moonlight, a crooked building came into Xia Di's eyes.

It is a two-story building that towers in the corner of the royal palace, the ground floor is thin, the upper floor is thick, obviously there are only two floors, but the cover is extremely irregular, it is simply the work of an abstract designer.

“…… Is it simply an illegal building? Xia Di squinted his eyes and looked at the building curiously for a while, until he saw the door number at the door of the building, and then he suddenly realized, "I wiped it, I thought it was, it turned out to be the Wang Family Library." ”

"Speaking of which, there's only place in this palace that I haven't visited."

The Royal Library is said to have been built by order of King Yusher.

The designer is unknown, but I have heard that it was built by a combination of dwarven craftsmen.

The library contains the originals of all the books published in Britain, as well as precious social science and alchemical books handed down from generation to generation by court mages and scholars, as well as royal history.

The library was theoretically only accessible to members of the royal family and officials who had applied for permission to enter, but since the death of King Uther, the library has changed its policy and allowed some professors from magical schools to come in and collect research materials.

That's right.

You may have the information you need.

Xia Di suddenly thought.

He remembered that the palace had set up a record officer for all the big and small things in the country, and the record content included people's livelihood, politics, and also the affairs of the palace, although the relevant memories of the people in the city may have been deliberately erased, but the text is not necessarily, even if there is no record of the information about the renovation of the palace two months ago, you can also reverse the reversal to find out the description of the building in the palace in the previous years, if there is information about the renovation in recent years, this means that unless it has experienced external destruction, Otherwise, there would be no need to renovate the palace at all.

"Let's look into this first...... After everything is done, let's talk about it. ”

After Xia Di finished thinking about it, he immediately rushed to the Wang Family Library.

Relying on the black fog and stealth, he dodged the hordes of patrolling guards along the way and made it to the door of the library without danger.

The so-called moon dark killing night, the wind is high and the day is set on fire.

Xia Di looked at the "illegal building" in front of him, and the urge to set it on fire rose in his heart, which was probably the mood of the urban management demolition brigade.

But he had come to steal the book tonight, so he resisted the thought of death, jumped and fell to the ledge.

Then he reached out and pressed his hand against the window, activated the [Detection] magic, and scouted the inside of the building.

"Huh." Xia Di raised his eyebrows in surprise.

…… No magic traps were found, not even defensive magic.

He thought that this library would at least be equipped with magic alarms and other troublesome things, and he had prepared a corresponding plan, but he didn't expect that there was nothing, could it be that there were no important books in it?

Xia Di visited the palace during the game, but he didn't come to this library alone, so he didn't know what was going on.

Forget it, since it's okay, let's go in.

"No, just in case, let's be prepared."

Xia Di jumped off the windowsill, did a little tricking, and after making sure that he was safe again, he jumped again, quickly broke the lock of the window with melting magic, and entered the library through the window.

At the moment, the library was empty, and there was an air of silence.

A faint smell of ink fills the air.

Xia Di closed the window and began to look for books from the second floor.

"Architecture, Literature, Society......"

I have to admit that the number of books in this library is not ordinary, although there are only two floors on the outside, but the internal space is very large, Xia Di scanned the rows of bookshelves three or four meters high, and estimated that there are at least more than 100,000 books in them, in addition to some real books in reality, there are also a small number of magic books and martial arts books, Xia Di read a few books with the mentality of trying, but found that it was not a skill book at all, but just a data book with rap words, a bit similar to the magic spell encyclopedia or the basic routine of weapons, etc, which is not useful at all.

Xia Di thought to himself, probably the important books were all moved into the basement by Merlin and hidden.

Thinking of this, Xia Di simply gave up the speculative psychology of looking for "martial arts cheats" and concentrated on finding records about Camelot City.

"Historical facts...... Ah, there it is. ”

It took nearly half an hour for Xia Di to finally find the information he wanted.

What he found was a book called "Chronicle of the City of Camelot", dated about a year ago, the author was a clerk in the court, and he also had some impressions of her name, Xia Di.

Bedwell, one of the Knights of the Round Table who resides in the royal palace.

"So she ever worked as a clerk......

Xia Di said in surprise.

He didn't know much about Bedwell, the Knight of the Round Table, so he didn't know much about it, except to wonder why a military attache would work as a civilian.

Xia Di immediately opened the book and read it carefully.

There is a lot of text in the book, but it is all a running account.

It took Xia Di a lot of effort to find the information he was looking for.

"Sure enough......" Xia Di closed the book, his face gloomy.

As he had suspected, the palace had undergone a major renovation five years earlier, led by King Uther of Britain, and since then the royal capital has not experienced natural disasters such as wars or earthquakes that would have damaged buildings, in other words, the palace's disrepair is a hoax.

Based on the information gathered along the way, Xia Di can already say with great certainty: "This palace is the palace where I killed King Arthur and caused the fire." ”
