The reason why Oscar didn't make a move on Xiao Wu but instead spoke these words to her was because during this time, he had figured out some things and had a new plan.
The simplest point is that soul beasts are now in a state of irreconcilable conflict with humans, but Oscar knew that in ten thousand years, the soul beast race would increasingly decline, because Soul Masters must hunt and kill soul beasts to obtain soul rings in order to advance their strength.
And now, Oscar was no longer limited to living a carefree life; he had greater ambitions and more worthy goals to strive for, so... he planned to use Xiao Wu to do some things.
Although he was also using Xiao Wu's identity, this also protected her. At least... he would do his best to prevent the things that happened in the original story from happening, because Xiao Wu would become an important part of his plan.
As for Gai Yue's ninth soul ring, Oscar had hesitated for a long time, and finally decided to give up on Xiao Wu, because he wanted his teacher to have more possibilities for improvement.
Although Xiao Wu could provide Gai Yue with a hundred-thousand-year soul ring and a hundred-thousand-year soul bone, which was completely sufficient in terms of quality, with Gai Yue and Dugu Bo's current strength, it was not impossible to hunt for a hundred-thousand-year soul beast more suitable for Gai Yue's ninth soul ring.
It would just take more time, but in terms of the final benefits, it was completely worth it.
That's why Oscar had this conversation with Xiao Wu.
Of course, it wasn't just because of Xiao Wu, but also because of Tang San. Tang San's feelings for Xiao Wu don't need to be mentioned; Xiao Sanzi was the kind of ruthless person who would give his life to protect Xiao Wu from harm. If Oscar could indirectly control Xiao Wu's weakness, then he would have more room to maneuver with Tang San.
Just take this time for example, although Tang San went to find Yu Xiaogang, and even though Oscar had made things very clear, Xiao Sanzi had six years of master-disciple relationship with Yu Xiaogang. He might break ties with Yu Xiaogang, but Tang San might also leave Shrek Academy because of this.
If at this time Xiao Wu chose to stay at Shrek Academy and also spoke up for Oscar, then Tang San would most likely lean more toward Oscar's side.
Although Oscar didn't have any dislike or liking for Tang San, if he could keep the protagonist of good fortune from the original story by his side, then in the future, Oscar could reduce some burden when doing many things.
After all, although Tang San didn't have the Ice Fire Yin Yang Spring this time, who could guarantee that other "cheats" wouldn't appear?
After all, with Oscar's current goals, letting Tang San leave his sight so early might cause him obstacles in the future.
Therefore, only by keeping him by his side could Oscar have more room to utilize him. After all, Oscar was not a saint; keeping Tang San by his side was also for better utilization of all his resources.
Otherwise, why would Oscar spend this time doing meaningless things?
Looking at Xiao Wu with moist eyes, Oscar said with an incomparably calm tone: "I don't need you to give me anything to thank me, and I won't use your identity to threaten you to do anything."
"But you must understand that in this world, no one is truly a good person, not even me. The reason I don't have other thoughts about you is because you haven't done anything outrageous so far."
"If in the future I find out that you have done something harmful to humans, I will personally take action to kill you."
"You, understand?"
Hearing these words, even though Oscar's tone showed no fluctuation, Xiao Wu understood that Oscar was just admonishing her that since she had become human, she should think for humans.
Xiao Wu nodded very solemnly: "I understand, Senior. I will remember your teachings today."
Oscar nodded: "It's good that you understand."
Then Xiao Wu asked somewhat cautiously: "Senior, besides you, does anyone else know my identity?"
Oscar glanced at Xiao Wu: "Who else do you think would know?"
Hearing this, Xiao Wu breathed a sigh of relief in her heart, and then said to Oscar with a pleading tone: "Senior, can I ask you for a favor? I promise, this matter absolutely won't put you in a difficult position."
Hearing this, a barely noticeable smile suddenly appeared on Oscar's face: "Don't tell Tang San about your identity?"
Seeing that Oscar had guessed what she wanted to say, Xiao Wu nodded her head vigorously as if pounding garlic: "Yes, Senior. Xiao San and normal humans are the same, their attitude towards soul beasts is a bit... so I'm afraid that if he knows my identity now, he might..."
Just as Xiao Wu was speaking, Oscar interrupted her: "Rest assured, he probably doesn't know your identity now, and I won't be so bored. Since I've decided to protect you, I must try to avoid extra trouble because of your identity."
Hearing this, Xiao Wu was instantly delighted in her heart, and also felt some warmth because Oscar said a sentence: "Decided to protect her..."
She didn't know why Oscar thought this way, nor did she know why he said this, but the calmness in Oscar's eyes could not be faked.
So when Oscar said these words, Xiao Wu bowed to Oscar again: "Thank you."
Oscar said: "Do you want to know how I saw through your identity?"
Hearing this, Xiao Wu suddenly raised her head. Although she didn't speak now, her desire for knowledge had reached its peak.
Oscar said: "Actually, if it were normal, it would at least require the strength of a Title Douluo or above to see through your identity, but I am different because my spiritual power is extraordinary."
Hearing this, although Xiao Wu was very surprised, if the person in question was Oscar, then it was easy to understand.
In Xiao Wu's eyes now, Oscar was simply a true genius prodigy, far from what Grandmaster could compare to.
Xiao Wu even felt that it would be better for Third Brother to follow Oscar for cultivation rather than study under Grandmaster! After all, Yu Xiaogang had taught Tang San for six years and occasionally brought her along, but she felt that Yu Xiaogang had taught Tang San for so long, which was even less effective than Oscar teaching for one month!
But at this moment, Xiao Wu naturally wasn't thinking about these things, because Oscar's next words made her even more surprised.
"And what really exposed you secondly was actually the sachet you carried on you. Although I had already guessed the origin of this sachet, the most important thing was what was inside it." Oscar said lightly.
Hearing this, Xiao Wu surprisedly took down the sachet from her waist, opened it, and looked at a green grass inside.
Xiao Wu knew this grass was very special because as long as it was watered daily, it could ensure it wouldn't wither, but she never expected that her exposure would be related to this grass?
Oscar continued: "This grass is called Breath-Concealing Grass. Its function is to help you conceal your soul beast aura. With it, even a Title Douluo cannot see through your identity. But what's special is that you must always wear it on your body, otherwise it cannot take effect."
"And when you were doing the swamp training before, you took off this sachet containing the Breath-Concealing Grass, which is how I discovered your true identity. Therefore, in the future, no matter what happens, you must never be separated from this sachet."
"Of course, you don't need to worry about it getting dirty, because the Breath-Concealing Grass itself has the effect of purifying filth and won't be contaminated by ordinary dirt."
Hearing this, Xiao Wu understood the function of the Breath-Concealing Grass and how to use it to protect her identity, but what made her most satisfied and believe was that the Breath-Concealing Grass was given to her by Tang San.
But judging from Tang San's performance, he really didn't know her true identity, but why would he give her this?
Oscar explained: "The one who really gave you the Breath-Concealing Grass was not Tang San, but his father. And I happen to know some secrets about his father, but I won't say more about it now because it involves many things."
"In short, you must remember one thing in the future: you must always carry your sachet, and it's best not to stay too far from me, otherwise I cannot guarantee your safety."
Hearing this, Xiao Wu was moved in her heart. But because of Oscar's admonition, even though she really wanted to ask about Tang San's father and why Tang San's father would give her the Breath-Concealing Grass, she couldn't bring herself to ask.
She didn't want to put Oscar in a difficult position, because he had just given her the greatest help.
