According to the information that Rhodes learned in his previous life, long before the arrival of the first players to enter the water elemental plane, the legendary mage of Bracada had already explored the "Hydra Trench".

The earliest record of the creatures in the "Hydra Trench" may date back to the golden age of Bracada.

However, as the years passed, in order to avoid the paper being too old, the mistakes made when handing it over to the mage's apprentice for copying, coupled with the series of destruction caused by the barbarian creatures caused by Tanan's war against Bracada, by the time Rhodes wanted to collect this information in his previous life, he was no longer able to find out about the "Hydra Trench" from Bracada's existing records.

Even in the face of such a situation, in the game of his previous life, Rhodes did not give up the search for this information.

Eventually, at great cost, Rhodes obtained from the Thieves' Guild a book originally written by a legendary mage, but by now, it is no longer known how many mage apprentices had copied it, which recorded the information that Rhodes needed.

In the face of the war that took place in Bracada, the thieves belonging to the Thieves' Guild were always able to maximize their interests at the first time.

When the war came and all the mages retreated, the members of the Thieves' Guild made the opposite choice, not fleeing the danger zone at the first time, but focusing on the precious things that originally belonged to the mages.

In this case, these thieves rescued these books containing precious information, naturally not because they were afraid that the books that recorded such important knowledge would disappear into the flames of war, but in order to wait until the war was over, and earn a large amount of gold from the mages who needed this knowledge.

Due to the existence of the Magic Guild, the Thieves Guild does not dare to openly disobey the orders of the mages and sell any level of magic, but the knowledge recorded by these legendary mages does not belong to this list.

Through the information recorded in the book, Rhodes learned that the Legendary Mage had explored the surrounding environment as early as when he ascended the land for the lower creatures of the Main Plane to inhabit, and that the concept of the forbidden land was first proposed by the Legendary Mage.

For the nearest forbidden place, the depths of the hydra trench, the legendary mage naturally launched an exploration.

From the information recorded in the book, Rhodes learned that the hydra trench at that time had not yet received its name, and the creatures that existed in it were not a huge number of multi-headed sea snakes, but only one kind of creature.

Through some of the details revealed in the book, whether it was about the spell casting method of its recorder, or some of his views on the water elemental plane, it made Rhodes clearly realize that the mage who had recorded this information had already reached the rank of a legendary mage, and even different from the legendary mage who had just been promoted, but had reached the middle of the seventh order.

It is such a legendary mage who still feels extreme heart palpitations when facing the creatures that exist beneath the trench.

In addition to the legendary mages who specialize in water-based magic, legendary mages who specialize in other systems will also be greatly limited when they are engaged in underwater battles, and it will be difficult for them to show their strength.

Under the influence of the rules of the plane, even if these legendary mages are reluctant, they can only use the magic related to the water system to fight, and cannot maximize their own strength.

According to the records in the book, this legendary mage who is good at earth magic, and came to the water elemental plane with other legendary mages for the rise of the land, and he is mainly responsible for the stability of the land plate after the rise.

As for the things recorded in this book, they are actually more like what the legendary mage himself has seen.

Even after countless years have passed, this book is no longer the original, but has been copied by many mage apprentices, and even the one that Rod got his hands on was also copied within the Thieves Guild before it was taken out and sold, but Rod was still able to get a lot of profound insights from the book.

According to the record of that legendary mage, even if his strength had already reached the seventh order and he had become the legendary mage that other mages aspired to, when he came to the elemental plane, he would still be shocked by the things that existed in it, and thus felt his own insignificance.

It is mentioned in the book that even if the many legendary mages in Bracada are gathered, all they can do with their combined efforts is to raise such a land in the water elemental plane.

Perhaps in the eyes of other mages, this was already a remarkable achievement, something that ordinary mages could not do anyway, but in the eyes of this legendary mage, compared to the boundless ocean that existed in the entire water elemental plane, this was nothing at all.

From the information recorded in the book, Rod could clearly feel the legendary mage's sigh for his own strength.

Perhaps when this legendary mage wrote this book, he did not deliberately express such an emotion, but only recorded some of his own opinions, but after being copied by many mages, what was recorded in the book was no longer the most primitive words, but the product of the interpretation of these mages.

Whether or not the mage who copied the legendary mage's thoughts over-interpreted, even Rhodes, who read the book, had no way of knowing this. Countless years later, even the legendary mage who recorded this book may be long gone, and Rhodes naturally has no way to obtain evidence.

However, from some of the information recorded in the book, Rhodes can also learn a lot of extremely important information.

From the information recorded in the book, Rhodes learned that according to the analysis of this legendary mage, the creature that existed in the depths of the trench was likely to have reached the peak of the seventh order, so that it could bring extreme heart palpitations to this legendary mage, and even make him have the idea of fleeing quickly.

Just in the closest forbidden place to the land where the legendary mage ascended, there are such legendary creatures, and it is conceivable how many powerful creatures there will be in the entire water elemental plane.

Because of this, all mages who have read the things recorded in the book can deeply feel the inferiority of their own strength from this information, so that when transcribing them, they can bring this idea into the original information in the book.
