"Will the contaminated and modified organisms leave the sea where they live? For example, after being polluted and modified by dragon blood, will a creature collected from elsewhere wander around and return to its original habitat? Tang Bai looked at Nott and asked again.

This question is something that Tang Bai must ask clearly.

The sea is so big, almost endless.

It is true that dumping dragon blood into the sea water and allowing the creatures in the sea water contaminated by the dragon's blood to evolve and mutate naturally is the easiest and most worry-free method, but the range of mutated creatures in the ocean is too wide, and many species will even migrate at a certain time.

Once some of the marine creatures after being polluted still have this kind of migratory characteristics, it will undoubtedly cause immeasurable damage to Tang Bai's carefully prepared defensive circle.

It was the mutated creatures that automatically left the sea area and swam elsewhere, which was a loss for Tang Bai. So Tang Bai couldn't help but ask Noether for an understanding of this.

"Under normal circumstances, sea creatures that have been contaminated by dragon's blood will not easily leave too far. Even if you leave for some reason, after a while, you will come back. But this situation cannot be said to be absolutely without exceptions. Some people who happen to pass through the sea contaminated with dragon blood, or have been specially collected from other places and received dragon blood pollution, may return to the sea where they originally lived after being freed. ”

Nott's face flew with a hint of hesitation, and he replied in a low voice.

"Is there any other way to keep all the creatures that have evolved and mutated after being contaminated by dragon blood in the enclosed sea?" Tang Bai was a little unwilling. If he can't solve this problem, then there will undoubtedly be a lot fewer creatures for him to choose from.

This is something Tang Bai is reluctant to do.

The more sea creatures to choose from, the stronger the defensive circle arranged by Tang Bai became. The Fountain of Youthfulness is also safer. If the Fountain of Immortality really had an effect on precious and strange magical plants such as the Clover of Life and Death Grass, its safety would not be compromised until Tang Bai found a better replacement.

Tang Bai didn't want the scene of the destruction of the Fountain of Youth, which he remembered, to be repeated in the future. Therefore, he can only protect and avoid it as much as possible before it happens.

"It's not impossible." Naute was stunned for a moment, and without Tang Bai asking again, he directly explained the solution, "You only need to place a few dragon scales from Norway in the sea area you need to protect." As long as there is still the breath of Norway in that sea, then the sea creatures that have been polluted and mutated by the blood of Norway will not easily leave there. They will remain like the most loyal soldiers guarding their high kings, in the waters where the Norwegian dragon scales are. ”

Nott glanced at Tang Bai as he spoke, "But this method also has flaws. ”

"What flaw?" When Tang Bai said this, he couldn't help but feel a little helpless in his heart. There are two sides to everything, there are more good than bad sides, or more bad than good sides. Nott's repeated words undoubtedly prove this from the side.

"The dragon scales with the breath of Norway can be confined to a sea area by the creatures that have been polluted and mutated by the blood of Norway, and can even expel some powerful sea legends. But if you encounter a legendary creature of the sea that is not afraid of the Norwegian dragon, then the Norwegian dragon scales are likely to have the opposite effect. Noether spread his hands.

"Backlash?" Mellen Watts blinked.

"In the concept of survival of living beings, the same region can only have one overlord! This is true even for humans who are highly intelligent beings. Once you encounter a legendary creature that is not afraid of the Norwegian dragon, then the creature that has been transformed by the blood of Norway and has a Norwegian breath will be brutally killed by the other party without mercy. ”

Notte said, looking at Tang Bai's expressionless face, he suddenly smiled again, and then comforted: "But this is only the worst, the possibility of happening." The sea is mysterious, but it is not unknown to wizards. ”

"In other words, the possibility you are talking about, to a large extent, will only be one possibility?" Hearing this, Tang Bai glanced at Nott, and whispered in a thoughtful voice.

"Yes. For the most part, it's just a near-impossible possibility. I don't know what kind of method you used to transform Norway into a hybrid dragon close to a pure-blooded ancient dragon, but in my opinion, in terms of bloodline and potential, Norway deserves to become the most powerful magical creature when it reaches adulthood. ”

"Maybe in ancient times, there were many species whose strength could be compared to half-blood dragons, or even pure-blooded ancient dragons, but now, whether it is land or sea, I don't dare to say that there are absolutely no magical creatures that can be comparable to Norway, but if you want to encounter it, it will take considerable luck."

"Therefore, this flaw is no longer enough to be regarded as a flaw in this era when the magical creature world and the wizarding world have almost shrunk and declined. That said, unless you're really lucky enough to get home and come across a magical creature as powerful as Norway's, you'll be able to sit back and relax with this method. ”

Knott said with a final conclusion.

Tang Bai was silent, his head spinning quickly and recalling. There is undoubtedly a lot of unrevealed secrets in the Caribbean world. But according to the information that has been revealed, the only strange creatures that can be regarded as powerful are Davy Jones's pets and mermaids.

Tang Bai hadn't personally verified their strength with these two creatures, but based on the information in his memory, if he was cautious, these creatures shouldn't pose any threat to Norway. From this point of view, it seems that the peace of mind that Noether said is not an untenable statement.

But this is definitely not a reason for Tang Bai to put his mind at ease.

There are still many people and unknowns in that world that make Tang Bai feel a little jealous for the time being.

"I have a suggestion, Don! If the island you care about is big enough, you can create a massive Dragon's Blood Stain on the island. The creatures of the island do not leave the island easily, and the hunting and danger are more powerful. Although there are many restrictions on the number and variety of creatures, it is a good defense. ”

For Tang Bai's silence, Nott was a little mistaken, thinking that he was having a headache on how to use the dragon's blood stain to arrange the layout of defenses, and he couldn't help but smile and suggest.
