The Great Annihilation was a turning point in all the history of this world, and it was also the beginning of today's so-called "Deep Sea Age".

According to what Nina said, Duncan finally roughly understood what kind of earth-shattering changes had happened in this world, and also realized that the world was not as weird and dangerous as it is now-

According to historical records, the world before the Great Annihilation was a prosperous and safe paradise.

At that time, the ocean was not an "infinite sea", when the limited sea did not occupy more than 95% of the world's surface as it is today, and at that time human beings still lived on vast and safe land, and even in the ocean, there were no dangerous visions such as the spirit world, the secluded world, and the subspace.

The "Age of Order" recorded in the history books felt more like Duncan's familiar world - although modern people look back with wonder and wonder at the ancient times when there were no "anomalies", for Duncan, the way the world looks today is completely wrong.

The history books do not provide a detailed explanation of the key event of the Great Annihilation, and despite the efforts of the archaeological community, there has always been great disagreement between the various city-states and peoples about ancient history, and no one knows exactly how the so-called Great Annihilation happened, nor what the ontology of the catastrophe really was - the great chaos and fog that shrouded the upheaval, and after the fog, it was already the current era of the deep sea.

Somehow the sea has flooded more than ninety percent of the land, the survivors of the remaining civilizations have built city-states and fleets on the remaining islands and small pieces of land, and the vast seas and sea fog have brought strange things called "anomalies" and "anomalies" that still threaten the survival of civilization today.

Unbeknownst to Nina, a ghost captain from a foreign land was learning from her words, she only thought that it was her uncle's lesson to the test - it had been a long time since her uncle had been in such a good mood, and she only felt very happy, and even felt that this moment was extraordinarily precious, because she was worried that Uncle Duncan would return to the way he was before...... And based on past experience, this is almost inevitable.

As soon as the liquor loses its effect, or the painkillers are consumed, the uncle becomes extraordinarily irritable, irritable, and hysterical.

So before Uncle Duncan got sick again, she wanted to show him all the progress she was making — maybe it would last him a day or two longer.

“…… Mr. Morris was very interested in the history of the Cretan Kingdom, and he was an expert in this area, and he told us that although the Old Kingdom of Crete only lasted for a hundred years, it was the first civilization to rise from the ruins against anomalies and anomalies after the advent of the Deep Sea Age, and the experience they developed over the centuries continues to guide most people in the world to this day - the most important of which is their classification of 'anomalies' and 'anomalies'......"

"Is there a way to classify 'anomalies' and 'anomalies'? Have you learned this? Duncan raised his eyebrows, and his words were still not forgetting to guide.

He had been very concerned since he had listened to it earlier, and only then did he become more and more convinced that in the eyes of ordinary people in this world, there should be a strict distinction between those things that do not make sense, some things are called "anomalous", and even numbered, but some things are ...... It seems to be called a "vision" separately, rather than a general classification of "anomalies" as he had in his previous impressions.

He'd never heard the details of this from the goathead on the Lost Nation before, and now what Nina had learned in school could finally make up for his lack of common sense.

Nina nodded, recalling what she had heard in class as she said, "Old Mr. Morris taught us the easiest way to divide anomalies and anomalies is scale.

"Generally speaking, anomalies are small in size and tend to be confined to one object, one animal, or even one 'person';

"Most anomalies can be moved by humans and have a limited range of effects, many of which affect only one target at a time, and most of them can be safely sealed or quarantined if they are mastered in a specific way—some of the more innocuous anomalies can even be 'exploited' by specific methods like tools.

"The scale of the vision is much larger than the anomaly, with the smallest vision being the size of a house, and the larger one covering the entire city-state, or even larger than that...... It's unimaginably big.

"A significant number of anomalies are immobile, either fixed in one place or operating on their own volition, and their ability to influence far exceeds that of anomalies. Normally, visions can affect an infinite number of targets within their own range of effect, so much so that they can almost be equated with 'natural phenomena', hence the name 'vision'.

"Unlike anomalies, almost all 'visions' cannot be sealed or controlled, they exist in the world like natural phenomena, operating without outside interference, and naturally affecting all eligible targets within range, and since most visions are dangerous, the only thing people can do is to stay away from these dangerous visions, or avoid becoming the target of the vision in a specific way......

"Fortunately, the most dangerous visions don't usually move, and the pioneers helped us detect them so we could safely keep our distance from them......"

Nina said very seriously, and then as if she suddenly remembered something, she quickly added: "Ah yes, the old gentleman also specifically mentioned to us, saying that these judgment methods and characteristics are only 'usually valid' - anomalies and anomalies are irrational things, so no matter how people sum up their experiences, there will always be anomalies or anomalies that do not meet the definition suddenly appear, and even sometimes anomalies and anomalies will be exchanged, and there are also cases where anomalies are interfered with and eliminated by manpower."

"For example, in 1830 in the city-state calendar, the city-state of Lensar had an anomaly called 'Mycelium' that went out of control, and the local church guardians banished the out-of-control anomaly to a nearby island at great cost, and that island was identified as a vision in 1835, which became the fungus island later—but in 1844, the great Saint Paladin took the fungal island into his urn at the cost of his life, so the vision 'fungus island' was removed from the list in the same year, and it became a 'fungus island' again. Anomaly', known as 'Paladine's Mushroom Bottle', is now sealed in the underground reliquary of the cathedral of the city-state of Renza......"

Duncan listened intently to what Nina had to say, his mind racing, and at the same time hiding the ups and downs of his heart with a calm expression.

In this short breakfast, he had gathered more information than he had spent so many days on the Lost Land combined!

Establishing communication with the land and setting up an outpost in the surface city-state is the right way to go—civilization is the collection of most of the world's information!

He subconsciously looked at the girl who was still talking in front of him, and felt quite a feeling in his heart.

A civilization that has developed normally to the industrial stage will definitely try to condense the basic knowledge of the functioning of society into its own education system, and it may be difficult for a child living in this system to realize what a treasure trove of textbooks they are exposed to on a daily basis:

It is the knowledge accumulated by countless people over countless years, and it has been integrated into the most suitable structure for learning and absorption through years of combing, and those books are constructed in the world's most exquisite "nutrient compression package", in order to make a blank sheet of paper can quickly become a part of social operation within the minimum cost of time and energy.

Even Nina, who is usually a lover of learning, can't realize this - only Duncan, a "foreigner", can realize how valuable and easy this knowledge is.

Nina didn't notice what Duncan was thinking, she just remembered what her venerable history teacher had said in class—

“…… Therefore, Mr. Morris said to us at the end of the last class, he said that people have summed up countless laws in the process of dealing with 'anomalies' and 'anomalies', but only one law is truly and forever valid, that is, 'no matter how many laws we have summarized, there will always be anomalies or anomalies that do not conform to the laws in the world'.

"This law, also known as the 'eternal zero' by scholars, is by default at the top of all books and papers in the field, and has led to the famous 'law of perpetual inaccuracy of anomalies and anomalies', which has not ......been broken to this day."
