Moreover, deep down, she had already accepted Chen Tingxue as her teacher's wife.

After all, Chen Tingxue, as the sect leader of the Wuji Sect, was of noble status and had outstanding strength, yet she was still willing to leave a place for Fang Han by her side, which already made her very satisfied.

Soon, Fang Han and Chen Tingxue took off together on their swords.

The sword gleamed with a lively light, tracing dazzling paths in the night.

The two of them were like two dazzling shooting stars, speeding across the vast sky.

At this moment, everything on the ground became incredibly small in their eyes, as if they were just ants under their feet, retreating at an extremely fast speed.

Before long, they arrived at the Yin-Yang Cave in Yin-Yang Mountain.

Standing at the entrance of the cave, looking up, one can see that inside the main cave of Yin Yang Cave, there are small cave dwellings scattered in a well-organized manner.

Upon entering the cave, one finds that the interior is fully equipped, with tables, chairs, and beds arranged neatly, and all the necessary items for cultivation, such as meditation cushions, are readily available.

Chen Tingxue couldn't help but exclaim from the bottom of her heart, "This is truly an excellent place for cultivation!"

It turns out that the Yin and Yang energies of Yin-Yang Mountain are chaotic and disordered, like a tangled mess. If an ordinary person were to cultivate here, they would definitely be disturbed by this chaotic energy. At best, they would suffer a qi deviation; at worst, they would lose their lives.

However, a special formation was cleverly arranged inside the cave.

This formation neatly organized the originally chaotic Yin and Yang energies, separating the pure from the impure.

In this way, this place became a blessed land for cultivation.

Outside the Yin-Yang Cave, apart from extraordinary individuals like Fang Han who possess the art of harmonious playing of the zither and lute, almost no one can cultivate in this chaotic atmosphere.

This is also why, although Yin-Yang Mountain is so rich in spiritual energy that it's almost tangible, apart from the remnants of the Hehuan Sect who secretly cultivated here, not many people are willing to come here to cultivate.

If Ouyang Yan and the others had not accidentally discovered the Yin-Yang Cave and the Yin-Yang Tree inside, they would not have chosen this place as their nest.

After all, the spiritual energy in this cave is far more concentrated than imagined, like a natural spirit-gathering array that continuously gathers the spiritual energy from the surrounding world.

The density of this spiritual energy is even higher than that of the spiritual energy in Chen Tingxue's cave in the Wuji Sect. It is truly a cultivation holy land that every cultivator dreams of.

"Taking advantage of this inky night, I will go outside to complete this breakthrough."

Fang Han led Chen Tingxue through the Yin-Yang Cave, his gaze sweeping over the various facilities inside. Then, he turned slightly to the side and whispered to Chen Tingxue beside him.

This Yin-Yang Cave is indeed a rare blessed land for cultivation, filled with spiritual energy. However, Fang Han knew in his heart that with the powerful energy he needed to release for this breakthrough, the commotion would be enormous.

If that immense power gets out of control, it could very well destroy the Yin-Yang Cave beyond recognition.

Therefore, to be on the safe side, he had no choice but to attempt a breakthrough outside the cave.

Upon hearing this, Chen Tingxue nodded slightly and followed Fang Han without hesitation, ready to protect him.

Soon, Fang Han arrived at a huge rock on a mountaintop outside the cave.

He quickly formed hand seals, and mysterious runes flew from his fingertips, instantly setting up an array to seal off the surrounding area.

Although Yin-Yang Mountain is located in a remote and desolate place, and few people usually come here, Fang Han knows that this breakthrough is no small matter. If it is not concealed, it may still attract unnecessary trouble.

After setting up the formation, Fang Han sat cross-legged, his eyes slightly closed, his expression calm and solemn, like a Buddha in meditation.

Immediately afterwards, he began to circulate the mysterious and powerful Creation Scripture.

In an instant, the true energy within his body surged like molten mercury, rapidly flowing through his meridians and emitting a series of low rumbling sounds.

At the same time, the spiritual energy from the outside world seemed to be summoned by some mysterious force, surging towards him like a tide, enveloping his entire body in a dazzling spiritual light.

As spiritual energy continued to flow in, Fang Han's aura began to surge at an astonishing rate.

Its aura was like a long-dormant dragon suddenly awakening, spreading wildly in all directions with a world-destroying majesty.

Around the cave in Yin-Yang Mountain, spiritual energy swirled wildly, forming a huge vortex. The vortex was shaped like a mysterious yin-yang symbol, with black and white energies intermingling yet clearly defined, emanating a chilling aura.

Chen Tingxue stood not far away, her eyes fixed on Fang Han. Seeing this scene, she couldn't help but feel a strong shock deep in her heart.

She knew that the Wuji Technique she cultivated was once regarded as the supreme technique. However, facing Fang Han, who was able to absorb a large amount of Yin and Yang energy between heaven and earth, she realized that the technique Fang Han cultivated far surpassed her Wuji Technique.

Fang Han's aura continued to rise, seemingly without end.

Chen Tingxue felt that Fang Han's aura was as imposing as a mountain and as vast as the sea, like a towering mountain that could suppress the world, majestic and unshakable.

She sighed inwardly, "No wonder Xiang Wantang, the number one expert of the Dragon Origin Sword Sect, once admitted that he was no match for Mr. Fang. Mr. Fang's aura is truly terrifying."

At this moment, Chen Tingxue felt even more strongly that befriending someone like Fang Han was absolutely the right thing to do.

In her view, the two of them could be both teacher and friend, learning from each other and exchanging ideas, and Fang Han would be a strong support she could rely on.

It should be noted that although she was the sect leader of the Wuji Sect, she was not the number one expert in the sect, and there were many people who coveted the position of sect leader and wanted to take her place.

However, Chen Tingxue knew in her heart that as long as her cultivation could advance by leaps and bounds and break through to the peak of the Yuan Dan realm in a short period of time, reaching the level of her master, Elder Baihe, those unscrupulous competitors would have no choice but to obediently submit to her.

Now, with Fang Han's careful guidance, she felt as if she had found a guiding light in the darkness.

She could sense that it wouldn't be long before she would have a breakthrough opportunity.
