When Liu Du withdrew his consciousness from the whirlpool, Liu Du was surprised to discover that a thin thread that was intertwined with black and white slowly formed, and afterwards, it continuously grew, growing very quickly. In an instant, the yin and yang filaments that was intertwined with black and white appeared in front of Liu Du.

This was exactly the same as the yin and yang filaments that the Little Golden Dragon had swallowed before, which had been spat out by the Yin Yang Pearl. Only, this was a yin and yang filaments that Liu Du had cultivated himself, and not with the help of the Little Golden Dragon.

At this time, Liu Du really wanted to know what stage his strength would reach after transforming into a yin and yang filaments!

But within Liu Du's line of sight, although the yin and yang filaments was born very quickly, it was like a drop in the bucket, relative to Liu Du's entire Dantian and meridians.

Liu Du sat there as he continuously circulated his inner strength into the whirlpool, and the whirlpool continued to give birth to an endless stream of yin and yang filaments!

In this short period of time, the amount of yin and yang filaments formed by the whirlpool in Liu Du's dantian exceeded the amount of yin and yang filaments that could transform into a large mouthful of inner strength absorbed by the Little Golden Dragon today.

Looking at the endless waves of yin and yang filaments being produced, Liu Du suddenly felt proud and elated. Damn, I finally don't need to ask for Little Golden Dragon anymore, just thinking about how I have been swept away by the Little Golden Dragon's tail multiple times before, Liu Du's heart filled with endless grief!

He was a dignified young master Liu, a future top expert, yet he was teased by a small dragon a few times. This was indeed a small stain on Liu Du's heart.

So when Liu Du saw that he was already able to produce yin and yang filaments on his own, he was greatly relieved. After that, Liu Du took a look at the Little Golden Dragon that was still writhing in the small cauldron, and said to himself: One day, I will ride you under my body, little fellow!

When the sunlight gradually rose, Liu Du was still sitting on the stone without moving. At this time, Liu Du was still circulating his inner strength continuously, and then, he turned into a black and white intertwined yin and yang filaments.

And at this time, Aunt Chen, who had just woken up, saw Liu Du, who had been sitting on a rock in the rear garden for an entire night. However, even after she had observed for around ten minutes, Liu Du still did not move an inch.

Furthermore, Aunt Chen clearly saw a droplet of dew that flickered with seven colored light, falling down from the grass vine above Liu Du's head. However, it suddenly shattered two inches above Liu Du's head, and under the shine of the morning sun, it actually formed a light rainbow in an instant, and disappeared from Aunt Chen's line of sight!

Aunt Chen looked at this mysterious and powerful man in a daze from the balcony, her eyes didn't stop moving for a long time. Knowing that the sunlight had passed through the gaps between the leaves and landed on his face, Aunt Chen suddenly realized that he had been silently staring at Liu Du for a long time!

One by one, the young ladies gradually got up. The morning sun was so bright and beautiful, and when the girls walked out of the villa to the back garden to breathe in the fresh air, they discovered Liu Du sitting cross-legged on the ground.

At this time, Liu Du was still quietly sitting on top of the stone, but he was as quiet as a rock, and it was as if he had stood there for thousands of years!

Even after the ladies had come to see Liu Du one by one, Liu Du remained unchanged. Furthermore, Li Xiaoyu seemed to have not left the garden after her conversation with her last night, and had instead been sitting cross-legged on this rock the entire time.

At this time, none of them were using ancient martial arts to cultivate, and none of them knew what kind of situation Liu Du was in right now. However, they could still slowly lift up Liu Du's stomach and see him still breathing non-stop.

As a result, no one dared to disturb Liu Du easily, as they were worried that it would affect Liu Du who was cultivating.

When everyone was full, they discovered that Liu Du still had not shown any signs of waking up, but the sunlight was already getting stronger and stronger, a portion of the sunlight shone onto Liu Du's body through the grass vines and leaves, and everyone seemed to see the light strangely refraction two inches in front of him.

Although Li Xiaoyu did not cultivate, she knew that Liu Du was definitely cultivating some kind of ancient martial arts, and had even reached a strange realm. Thus, from the very beginning, when they first saw it, they had constantly warned everyone to not let anyone disturb Liu Du, and at the same time, prevent other things from disturbing Liu Du!

However, Liu Du did not wake up even though everyone was swaying in front of him. He was like a sleeping lion, whose chest was undulating nonstop, and was unable to open his mouth.

At that time, Li Xiaoyu would still be not far from where Liu Du was sitting as he sat cross-legged. His two big eyes were blinking non-stop, and no one knew what she was thinking about!

At this time, Liu Du was still unceasingly circulating his inner strength, the continuously regenerating inner strength was like a moth pouncing into a flame, and soon after, a black and white intertwined yin and yang filaments appeared.

Time continued to pass, and yet Liu Du did not wake up for the entire day. Just like before, he sank into silence, and sat cross-legged atop the stone!

"brother Du, what's wrong with him? Why hasn't he woken up? "

At this moment, Wen Xin was looking worriedly at Liu Du. After all, with Wen Xin's classical and gentle personality, it determined that she would have a very important impression of her first man, and adding Liu Du's serious and hard work in treating her mother's body, the effect was extremely obvious. Wen Xin had long said that if someone was able to save his mother, even if she promised him, she would not regret it.

However, when the Li Xiaoyu at this time heard Wen Xin actually change her address to brother Du, his eyes slightly lit up, and then looked at Liu Du who was still silent, and softly replied: "I know he is cultivating, but I don't know why he is still sitting cross-legged on top of the stone. It had been over ten hours and he was still sitting there steadily. It looked like there shouldn't be any problems! Right now, we have no other choice but to wait for him to wake up alone! "

When his mother had the hope of recovering, Wen Xin had decided to give up on all of her previous grudges. As long as his mother was well, Wen Xin would seriously become her woman, and even if it was a request from Liu Du, he would do it herself.

At this time, Liu Du's figure had already slowly become branded in her heart, and even if it was at this moment when she saw Liu Du's naughty smile, it would still make Wen Xin happy, but Liu Du still did not wake up.

The sky gradually darkened, but Liu Du once again felt the feeling of darkness during the day!

What he felt before was yin and yang, but now it was yang and yin, a complete transformation. It was the most real change in nature, without any hint of adultery. This was the power of nature!

At this moment, Liu Du felt that the Yin-Yang Formula had another kind of comprehension, a different kind of circulation method!

However, this time, it was true that the whirlpool was the same as before, but the whirlpool was gradually shrinking. When the whirlpool was shrinking again, Liu Du discovered that it had completely become a spinning white pearl, but his surroundings were completely black, as though a black whirlpool was wrapping around a white bead.

After seeing this astonishing scene, Liu Du earnestly observed the whirlpool that had formed in the morning. However, he realized that the whirlpool he had seen was only the light emitted by the black bead as it spun.

Soon after, Liu Du once again discovered that the yin and yang filaments he saw before was not really a yin and yang filaments. It was just a white thread produced by the black bead, but it emitted a black light. The continuously spinning white line and the black light it emitted gave Liu Du the feeling of a black and white yin and yang filaments.

It was only now that Liu Du finally felt the perfection of the doctor's Yin-Yang Formula. Of the two continuously rotating pearls, one emitted a white glow while the other white emitted a black glow.

The white pearl gave birth to black silk which emitted white light, while the black pearl gave birth to white silk which emitted black light.

Yin gave birth to yang. Yang gave birth to yin. It was a completely magical picture.

Of course, this picture wasn't complete yet. When the two balls were the size of vortexes, they seemed to attract each other's attention. The two pearls rotated non-stop, and at this moment, the two nearby spinning pearls both lost their strange glow.

Following the rotation of the two pearls, the opposite black and white color that the two pearls gave birth to coiled together for the first time.

Liu Du suddenly felt as if his strength had greatly increased, and even his own flesh and blood seemed to have solidified!

At this moment, Liu Du discovered that this was the true yin and yang filaments. After each black and white intertwined yin and yang filaments was born, Liu Du instantly felt that his vitality had increased. At the same time, his various spirit senses, senses, senses, hearing, and taste were all increasing.

Moreover, these newly formed yin and yang filaments also contained an extremely strong vitality. Knowing that at this time, Liu Du finally felt that it was too early to be happy in the morning, and it caused the real two o'clock yin and yang filaments to appear, Liu Du could already view them very calmly!

From the intersection of the two continuously spinning beads, Liu Du felt that the speed at which the yin and yang filaments appeared had become faster!

The meridians in Liu Du's body were still revolving nonstop, causing the inner strength to enter the two black and white revolving round beads inside his Dantian continuously, and then the black and white yin and yang filaments started to wrap around it and come out!

At this moment, Liu Du finally saw the true yin and yang filaments in front of him!

However, Liu Du realized that the speed at which the yin and yang filaments was producing was truly fast, to the point that the Little Golden Dragon that was playing non-stop inside the little cauldron was now opening its mouth wide and staring with its eyes wide open, staring stupidly at the black and white spinning bead formed by the two swirls outside the little cauldron, and the black and white yin and yang filaments that was born.

And the yin and yang filaments that was naturally produced in Liu Du's body actually had a much richer life force than the yin and yang filaments that was refined by the Little Golden Dragon!

Liu Du was currently very happy. This should be the real Yin-Yang Formula of the doctor, right?
