I am the son of the Dragon God in Douluo Continent.

Xu Xingyu looked at Ma Xiaotao, whose yin and yang were already out of balance, with a sense of helplessness. He really didn't expect that Ma Xiaotao would try to switch yin and yang without telling her teacher and him, the healer.

It's easy to say that creating a yin-yang vortex inside the body is simple, but in practice it's not that easy.

The safest approach would have been to use external force to help the Yin Fire within Ma Xiaotao's body grow to the point where it could rival the Yang Fire within her body.

Then, after the two sides are completely balanced, a yin-yang vortex is created to perform yin-yang transformation.

However, Ma Xiaotao did not do that. She first constructed a yin-yang vortex inside her body, and then used the vortex to transform her excess yang fire into yin fire.

Although it's just a matter of reversing Xu Xingyu's order, the actual difficulty is greater than the original order.

Because the Yin-Yang vortex also has its limits; it cannot convert too much Yang fire into Yin fire at once, otherwise the vortex would easily break.

Ma Xiaotao's current situation is that she has indeed successfully converted some of the yang fire into yin fire.

However, this also caused the previously silent Yin Fire and Evil Fire to erupt within Ma Xiaotao's body, attempting to devour the remaining Yang Fire as well.

However, the Yang fire within Ma Xiaotao's body was not to be trifled with. Upon sensing the movements of the Yin fire and the evil fire, it actively clashed with both, triggering the Phoenix bloodline within Ma Xiaotao's body to resist the two fires.

Resolving this situation of three fires vying for supremacy is not so easy.

The only method Xu Xingyu could think of was to use the chaotic energy in her own body to harmonize Ma Xiaotao's Yin and Yang fires.

Since Xu Xingyu's Origin Star Celestial Body Technique has not reached the Great Completion stage, he currently only has a pseudo-chaotic core (the specific content of the Origin Star Celestial Body Technique can be found in the prequel).

Therefore, the amount of chaotic energy in the body is also limited and cannot be squandered at will.

Fortunately, balancing the Yin and Yang fires doesn't require too much chaotic energy, so this is still within Xu Xingyu's tolerance range.

The biggest problem is how to prevent the evil fire from causing trouble when he is balancing the two fires.

Just then, Jiang Nannan suddenly asked, "Is there anything I can help you with?"

Upon hearing this, Xu Xingyu immediately turned to Jiang Nannan, and Jiang Nannan continued, "After all, Sister Xiaotao is my friend, so if there's anything I can do for you, please let me know."

Seeing Jiang Nannan's earnest gaze, Xu Xingyu could only nod in agreement.

It was at this moment that Xu Xingyu thought of how to deal with Ma Xiaotao's problem!

That is to have Jiang Nannan use the power of her Taiyin Jade Body to fuel the Yin Fire in Ma Xiaotao's body, while Xu Xingyu will use the power of chaos to separate the evil fire from the Yin and Yang fire.

This will prevent the evil spirits from causing trouble and making things worse.

Once Ma Xiaotao's Yin and Yang Fires are completely balanced, Xu Xingyu will use extreme ice to suppress the evil fire and then quickly help Ma Xiaotao establish a Yin-Yang vortex.

That will make everything perfectly fine!

The only problem is that before Ma Xiaotao can completely transform the evil fire into pure fire element, she needs to have Xu Xingyu help suppress her evil fire every now and then.

Actually, this is no different from the agreement between the two of them, except that the original first plan has been changed to the second plan.

There's no time to lose; now that the course of action has been decided, we must act quickly. Only in this way can we resolve the immediate problem as soon as possible.

After explaining to Jiang Nannan what she needed to do and the precautions, the two began to help this senior student, who was always troubled by evil fire, balance her flames.

The overall process went very smoothly. While Jiang Nannan was stimulating Ma Xiaotao's Yin Fire, the Evil Fire did try to cause trouble quite a bit, but in the end, Xu Xingyu used the power of chaos to block it back.

After an unknown amount of time, Ma Xiaotao's complexion improved significantly, and the two flames within her body were completely balanced.

Seeing this, Xu Xingyu began the next step, and a small, milky-white flame appeared in her hand.

This is the Chaos Flame created by Xu Xingyu by fusing her own Chaos Power and her Ultimate Flame. It is also the highest-level form of flame in this Douluo Continent story.

Guided by Xu Xingyu, the small flame entered Ma Xiaotao's body and began to entangle with the Yin and Yang energies within her.

Soon, upon sensing the majesty of the Chaos Fire, even the Yin and Yang Fires, which disliked each other, gradually calmed down and began to rotate in a peculiar way.

The Yin-Yang vortex has completely formed inside Ma Xiaotao's body!

At this moment, Ma Xiaotao also fully regained her senses. Seeing Xu Xingyu and Jiang Nannan, who were already panting, she quickly bent down and said:

"I'm so sorry to have interrupted your date!"

After all, Ma Xiaotao isn't blind. Judging from Xu Xingyu and Jiang Nannan's outfits, the two must have wanted to enjoy the scenery of Poseidon Lake during their date.

However, he barged into their date because of a problem he encountered during his cultivation. Anyone would be unhappy about that!

If they were strangers, that would be fine; I could use my status as a senior in the inner court to shut them up, and at most, I could offer some compensation afterward.

But who are these two people in front of me?

One was her very close friend, and the other was her attending physician.

If she really dares to do that, then there's no point in having friends or getting treatment!

Seeing Ma Xiaotao's apologetic face, Jiang Nannan quickly helped her up, saying, "Sister Xiaotao, don't be like this. We're friends, isn't it only natural to help a friend in need?"

Seeing that Jiang Nannan had forgiven her, Ma Xiaotao breathed a slight sigh of relief, and then secretly looked at Xu Xingyu.

After all, her relationship with Xu Xingyu was only that of someone she had known for a short time. It was certainly much stronger than that of strangers, but they hadn't reached the level of being friends yet.

Xu Xingyu looked at Ma Xiaotao with a stern face, giving the impression that it was impossible to tell what he was thinking.

Ma Xiaotao felt immense pressure under Xu Xingyu's silent application, fearing that the other party might say they didn't want to suppress her lustful desires.

Just as Ma Xiaotao was about to say something to ease the tension, Xu Xingyu finally spoke:

"Starting today, you must come to me once a week to suppress your evil fire. You are not allowed to refuse. In your current condition, even if I suppress your evil fire, it will still erupt every week."

This answer stunned Ma Xiaotao. In her mind, Xu Xingyu would probably curse her out, perhaps because the date was interrupted, or perhaps because she hadn't fulfilled her promise to him to create the Yin-Yang Vortex, or perhaps both.

Seeing Ma Xiaotao's astonished expression, Xu Xingyu seemed to know what she was thinking and said, "The reason I didn't say anything is because you're the kind of person who, once you've made up your mind, will see it through to the end, no matter how much I try to persuade you, you'll still do it."

"Therefore, you've wasted your time. I might as well have modified the treatment plan I gave you according to your ideas. Just next time, please tell me your plans in advance and don't bother me when I'm on a date. After all, I'm your doctor, not your babysitter."

Hearing Xu Xingyu's words, Ma Xiaotao also got angry. It felt like Xu Xingyu was indirectly insulting her as a stubborn and brainless woman.

However, since Ma Xiaotao was in the wrong, she suppressed her anger and decided to listen to Xu Xingyu.

After all, the method to cure her evil fire was carried out by Xu Xingyu, so his words carried the most weight.

At most, she would complain about Xu Xingyu in her heart, but even her parents had never said such things to her!
