The mermaid wasn't too sure if Yale's words were trustful, but she knew that there are people who act for such motives and believed that her own brother would have acted in the same way if he found Yale protecting his little sister and needing help.

She thought that those who were kind with foreigners had a second intention or were stupid because she couldn't believe that someone would help others without any reason.

Of course, due to Yale speaking about his little sister, the mermaid ended putting Yale in the group of stupid people that would help others due to reasons like resembling someone else.

Yale didn't know what that small mermaid was thinking of him, but he didn't care as long as he managed to establish a good relationship with those two. After all, his main reasons for diving was obtaining information about the Sea Race, and although he didn't know if those two were of the Sea Race, they might know valuable information.

Thus, he would rather be considered a fool and obtain some trust than being considered a crafty person.

"I am sorry for being rude. If you can help my big brother, I will be really thankful to you."

After determining that Yale was only a fool, the mermaid decided to stop being so wary of him, she didn't trust him completely, but she also saw that Yale despite being stupid was also very powerful, so she really hoped that her brother could be saved.

Yale manipulated the water to execute Water Healing though Water Control, that was another advantage of Water Control, it could be used to execute other water-based skills without additional cost.

The mermaid and her brother were shocked as the wounds quickly healed, even the tail was quickly regenerating, which was even more impressive as the damage was far too serious and they thought that even if the life could be saved, the tail would remain in a damaged state.

In fact, although those siblings thought that the speed was too quick, Yale felt that it was too slow compared to Time Healing, but he didn't want to waste Origin Points in Time Healing when he could just use Water Healing without an additional cost.

"Thank you very much!"

The merman was extremely happy when he felt that his body had been completely restored in such a short span of time. Even the mermaid who was still wary of Yale had a new impression of him after seeing the power of his healing skills.

"Who are you? Why someone like you is here?"

The questions the mermaid asked at that moment weren't normal because they were infused with illusions making that anyone who hard it to be mesmerized and reply honestly. Usually, using the real voice was needed, but there were some mermaids with talent that could do the same with Spiritual Sense making that it was impossible blocking it just by stopping to hear.

The merman was about to say something when he noticed that his sister was too rude to their savior, but he wasn't able to say anything before Yale spoke.

"Little girl, I know that you are curious about me and you don't have bad intentions, but I need to tell you that illusions are useless against me."

Neither of them expected that Yale wouldn't be affected by the mermaid's voice; they knew that Yale was stronger than them, after all, the mermaid was just at the Apprentice Rank, and the merman was only at the Practitioner Rank.

However, the merman knew how skilled his sister was with illusions; even a Grandmaster Rank expert had been a bit affected time ago. That kind of effect was abnormal, even with the inherent strength of the Innate Mesmerizing Voice, affecting someone two ranks ahead was already very good. Sadly, that type of illusion didn't work very well with monsters that only moved by instinct.

They were unable to sense Yale's true level, but since he looked pretty young, they didn't think that he would be at the Sage Rank.

"Why the two of you look so shocked? Not even a Law God would be able to use an illusion against me, much less you two. It isn't that your illusion skill is bad, but I am probably the worst target in the world to cast an illusion skill."

Yale wasn't angry at all; he was feeling funny the faces of those siblings. Yale had read in books about the mesmerizing voices of mermaids and how could control the men, but until that moment, he didn't know if that was just a story or was real at least partially.

He verified that mermaids could use illusions even with Spiritual Sense, which was even scarier than just the normal voice, and he was the target of an illusion made by a mermaid, making him feel like one of the characters of the books he read when he was a child.

Of course, the mesmerizing voice couldn't affect him, no matter how powerful a mermaid's innate mesmerizing voice was.

"Not even a Law God..."

Both siblings repeated at the same time in shock; they had heard of Law Gods in legends despite have never seen any Law God personally, and those figures were literally like gods for them. Thus, hearing someone ensure that not even Law God would be able to make him fell into an illusion was a great shock.

"Are you a Law God?"

The merman put all his strength is asking that to Yale, he couldn't believe that such a legendary figure had appeared before them and saved their lives.

"I am not a Law God. It is just that I have innate immunity to all kind of illusions making that not even a Law God could force me to fall into an illusion."

Yale didn't plan to explain all the story about his reincarnation nor how he had killed Law Gods before because he couldn't do the same at that moment and didn't want to put too many expectations on himself.

"So, it is something innate like the power of infusing illusions in our voice from our race. You truly are the worst possible target to cast illusion skills."

The merman laughed after saying that, he felt relieved that the other party wasn't truly a Law God because he wouldn't know how to act in front of someone that powerful.

The mermen and the mermaids had that innate power in their voices, and the illusions provoked by their voices were far more dangerous than those used in the Kurk Clan to slightly manipulate the clan members. After all, infusing illusions on the voice was extremely difficult and the mermen and mermaids could do it only because they had born with that capability.

The same applied to Yale's Illusion Immunity, that wasn't something that could be easily obtained through training, and even obtaining a bit of immunity would at most work with illusions cast by someone weaker, but a complete immunity like Yale's was something he had from the start because the system was in his soul.

"I have read in books about a race in the ocean that has that capability of infusing illusions, but I never expected it to be true."

Yale laughed after saying that. Fortunately, he didn't need to fear the water surrounding him because laughing like that the water would have entered his body.

"Oh, so there is some information about us. I have also read about humans, but there wasn't any information about any Illusion Immunity, usually in the stories the humans were always easily affected by our mighty illusions."

The mermaid's interest was caught at that moment since Yale started to speak about books because she loved reading those stories although that made others look at her with disdain as they considered that she was wasting her time.

"I doubt that there are some other humans with this capability. I am sure that anyone else will easily fall into your illusions."

Yale was pretty sure that of all the people in his storage Space, only Aiwai, Sebe and Swordmad would be able to resist the illusion of that girl.

"Well, maybe Lar and Ange as reincarnated experts would be able to also resist it."

Although he thought about that, he didn't speak.

At that moment, the mermaid seemed happy because she always dreamed about cheating some humans with her mesmerizing voice like in the books she had read. Of course, she didn't have any bad intention like in most of those books where humans had bad fates after being mesmerized; she only wanted to have the experience of cheating them with her voice and made them act like fools for a while.

"So, it is like that. No wonder you are the only human that dared to come to this place, the others are far too scared of our illusions."

The mermaid was in a very good mood at that moment, and she completely forgot about the fact that Yale was a foreigner. After all, she was only was eleven years old; she was just a kid.

The merman was a bit older than her, but he was only fifteen, and he had a quite a simple personality, so Yale obtained his trust from the moment he saved his little sister.

In that short span of time, Yale hadn't obtained any critical information but had managed to obtain the trust of those two, which was the first step in his plan of obtaining information.
