Merlin eventually took the book of demons out anyway.

It's not because I heard Ursula say that she is a mermaid, so she is hungry for other people's bodies, but for another reason.

emmmm, well, in fact, Merlin is still quite curious about mermaids or something, but it's really only curious, after all, the mermaids in this world are really a bit too ferocious.

Unlike the innocent and kind mermaid that Merlin saw in fairy tale books in his previous life, the mermaid in this world is a veritable nightmare in the sea.

First of all, it must be stated that the sea of this world has never belonged to human beings.

In the ancient dark ages, the whole world belonged to those transcendent races, and then the Lord of the Flame rose and slowly led mankind to occupy the vast continent, but it also stopped at the continent, and for the more vast ocean beyond the continent, human beings can only be helpless.

The sea, especially the deep sea, has long been controlled by the power of the abyss, and the water is fireless, no matter how strong the Lord of the Flame is, it is impossible for him to burn the entire sea dry, even if he really has the ability to burn, it is impossible to burn, after all, this is basically equivalent to destroying the world.

Therefore, the situation in the sea is still no different from that of the Dark Ages, and God knows how many sea monsters or otherworldly races are hidden in the deep sea.

During the day, the monsters may be a little more afraid of the light of the Lord of the Flame, and the human fishermen can still fish in the offshore waters, but at night, all the fishing boats must return to port, because the sea at night is nocturnal.

The ceiling of combat power in the sea has always been the sea dragons of those dragon clans, but the number of dragons is only a little bit, and the dragons are notoriously lazy, they will be rampant and domineering, and it is not a problem to make a small territory, but the founding of the country is serious and rules the entire ocean, which they are really not good at.

As a result, the throne in the sea naturally fell into the hands of the merfolk of the silver species.

The mermaid is a typical mother-style clan, and the female mermaid is the classic shape of the human body and fish tail, all of them are gorgeous, worthy of the title of mermaid, and at the same time strong.

The mermaids have beautiful singing voices, can tempt passing ships with their charming songs, and at the same time, they can also operate ocean currents, have the ability to set off storms at sea, and have the ability to communicate and dominate the sea monsters, etc., in short, they are the top strength of the standard silver race.

But the male mermaid is a little miserable, it is the shape of the fish-headed human body, the appearance is ugly, and at the same time, all abilities are basically a weakened version of the female mermaid, and the degree of wisdom is not high, so it only has the strength of the bronze level.

It is also because the gap between the two is so great that the academic community is reluctant to admit that the two are actually the same race. So, in order to distinguish between them, only the beautiful female mermaids are still called mermaids, while the ugly male mermaids are contemptuously called fish people.

It's just that all the beauty that has been said is actually the appearance and strength of the mermaid, as for the character.....

This is really unacceptable, compared to the species of the abyss camp, so it is not uncommon for the mermaid's recipe to contain humans, and there is even a legend that the mermaid in estrus will use a singer to tempt human sailors to have sex with them, and then kill the sailors and eat them as nutrients after pregnancy, I don't know if it's true or not.

Therefore, this terrible race with the habits of praying mantis, Merlin really does not dare to be greedy, and he can't afford it.

The reason why he ended up bringing this demon book with him was simply because Ursula had told him an unspoken rule about the Forbidden Book Library, where if a forbidden book was chosen as a target, no other banned books would attack that target until the forbidden book was abandoned.

This time I didn't find the inheritance left by the brave father, so Merlin will inevitably have to run to this forbidden book library often, although he is not very afraid of the temptation of those forbidden books, but more is better than less, since there is this unspoken rule, then Merlin will save a lot of trouble next time.

So, Merlin thought about it again and again, and finally made a deal with the Demon Book.

Even in order to win Merlin's trust, Ursula swore allegiance to the Abyssal Consciousness that he would henceforth be loyal to him.

This made Merlin really shocked, after all, this kind of oath is different from the kind of contract signed between demons and humans that can be torn up casually, especially the designated object of this oath is still him, the demon king, with the degree of care that the abyss mother is now for him, even if the demon god of the seven deadly sins dares to break the contract, he will not die and will shed his skin.

"So, I have an extra demon god-level subordinate in the abyss, isn't this too fast, will there be a suspicion of being condemned?"

After leaving the forbidden library through the ritual of tossing a coin again, Merlin looked down at the Demon Book in his hand, which had retracted into the appearance of an ordinary book, and sighed in his heart.

However, he didn't feel happy because of this, or because he had more god-level subordinates, after all, he didn't have the ability to summon Ursula's body from the abyss now, and a demon god-level great demon came to lick him at all costs, what was the reason behind this?

It can't be because he is so handsome, so he fell in love with him at first sight, right?

As soon as such a speculation came to his mind, Merlin immediately shook his head and rejected this unrealistic speculation.

Although he is indeed quite handsome, but this handsomeness is still in the category of human beings, but in the abyss, there must be a lot of magic in the app value higher than him, such as succubus or something, what kind of handsome guy has never seen a dignified demon god, how can there be such a ridiculous thing as love at first sight.

"So, is there any secret that my identity as a demon king doesn't know about, and it's not completely fake?"

Merlin thought with a frown.

As he thought, he entered the state of the shadow body and walked stealthily all the way to the school gate.

Unbeknownst to Merlin, the silent bickering between the Serpent and Ursula continued.

"Wow, you shameless dead fish, you have done such kneeling and licking, haven't your lover fetishes been good after so many years?"

The snake looked disgusted.

"What is a lover's fetish, I'm a mermaid, half human and half fish, so is there anything wrong with aesthetics biased towards humans? This is normal, okay, who made those fish people ugly, I was disgusted when I saw the fish head, and I couldn't accept it physiologically, you don't have a lover fetish, so why don't you find a snake man with a snake head to marry. ”

In the Book of Demons, Ursula retorts unconvinced.

Snake: "......."

She thought about the appearance of the snake-headed snakemen for a moment, and then shook her head vigorously.

Well, she also accepts that she can't.
