Yin and Yang meet, water and fire complement each other, this is the ultimate way of heaven and earth.

No matter whether it is humans, demons, gods, Buddhas, or even evil spirits and monsters, there is a distinction between yin and yang, and between truth and falsehood.

Gao Xian and Xiao Lingqin practiced dual cultivation, and Gao Xian learned all kinds of exquisite secret techniques of dual cultivation of Yin and Yang, which also enabled his Yin and Yang enlightenment to be advanced three levels.

This time, practicing dual cultivation with Yin Jiuli was less interesting, but more mysterious changes of the fusion of yin and yang.

Yin Jiuli had been cultivating the Yin-Yang sword for three hundred years, and in terms of purity, it was much better than Gao Xian. Gao Xian's advantage was his strong spiritual consciousness and profound sword intent. Although he had only just started to learn the Yin-Yang sword, he was able to fully cooperate with Yin Jiuli.

The Yin-Yang Sword and the Pole-Yang Sword are two sword techniques derived from the Tai Chi Sword Sutra. The difference between them is that one is directed inward and the other outward.

Both sword techniques expound the ultimate truth of Yin and Yang. When combined, the inside and the outside are extremely harmonious, subtly imbuing themselves with the idea of ​​reversing Yin and Yang and recreating Tai Chi.

Gao Xian and Yin Jiuli both sensed the wonders of the innate Tai Chi through the fusion of body and spirit through dual cultivation...

Unfortunately, their cultivation was not enough to comprehend the wonders of the innate Tai Chi, and they could only barely maintain this state. Through the fusion of body and spirit, Gao Xian and Yin Jiuli both gained the profound sword intent from each other, and also completed a real combing of their own swordsmanship from the inside out.

After several days, the Yin-Yang sword intent on Gao Xian's Taiyuan Shenxiang was completely dissolved. He also learned the changes of Yin and Yang in the two poles, and compared it with his own Yin and Yang, he gained a lot.

His consciousness sank into the Taishi Temple, and when he opened the Fengyue Treasure Mirror, he could see that the Polar Yin-Yang Sword had reached the level of mastery.

Under normal circumstances, it would take him at least seventy to eighty years to practice step by step to reach the level of proficiency.

The dual cultivation effect is so good, it is because the two swordsmanships are naturally compatible. Yin Jiuli has accumulated sword energy and sword intent for three hundred years, and it is pure enough. He also cooperates well.

What surprised Gao Xian was that his Yin-Yang Enlightenment Sutra had actually improved significantly, and was about to reach the master level.

Through this dual cultivation, Gao Xian discovered that the two secret methods actually had a lot in common. It can only be said that the heaven and earth have the same origin and all methods have the same root.

When you reach a certain level, you will find that all things and phenomena have something in common.

This discovery also made Gao Xian a little excited. Since the Bipolar Yin-Yang Sword can improve the Yin-Yang Enlightenment Sutra, can it work the other way around? This still needs to be verified through experiments. If the two can really be connected, it can save him countless troubles.

In fact, Yin Jiuli gained more from this dual cultivation. Her Yin and Yang always lacked the innate Yang energy, and even though she had magical pills to make up for it, it was still a level short.

Through dual cultivation with Gao Xian, she was able to truly achieve a balance between the yin and yang of the two elements, which in turn elevated her swordsmanship to a higher level, and her cultivation base reached the peak of the tenth level of the Nascent Soul.

At this point, Yin Jiuli was already able to touch the realm of transformation. She had a clear understanding that if she continued to practice dual cultivation like this, within thirty years, she should be able to complete the tempering of her own sword will and sword energy and reach the perfect state.

Thinking of this, Yin Jiuli opened his eyes and looked at Gao Xian who was standing opposite him. Gao Xian was wearing a white shirt with most of his chest exposed.

His skin was smooth as jade yet extremely firm and full of endless power.

Gao Xian sensed Yin Jiuli's gaze, he opened his eyes and smiled at Yin Jiuli. However, Yin Jiuli blushed slightly, showing a bit of embarrassment.

The slight change in expression made Yin Jiuli look more charming.

Yin Jiuli is not the kind of stunning beauty that you will never forget at first sight, but she has an extraordinarily graceful demeanor that is very pleasing to the eye.

Gao Xian gently put his arm around Yin Jiuli's shoulders and said softly, "Jiuli, I really hope we can stay together forever..."

Yin Jiuli's body trembled slightly. She knew in her heart that she would never leave Taiji Sword Palace. Gao Xian was also unlikely to join Taiji Sword Palace.

No matter how close she and Gao Xian were, they couldn't be together. She held Gao Xian's hand tightly and whispered, "I am lucky to have Senior Brother's gentle love. How dare I ask for more."

“It’s my luck…”

Gao Xian said casually: "With your talent, you will definitely reach the pinnacle of swordsmanship in the future. Don't forget me when the time comes!"

Yin Jiuli looked directly at Gao Xian with his bright eyes and said seriously, "I will never forget this in my lifetime."

Gao Xian was a little uncomfortable with Yin Jiuli's seriousness. He pulled Yin Jiuli over and said with a smile, "Jiuli, there are still some things I don't understand about swordsmanship. Let's study it further..."

Yin Jiuli's face turned even redder, and she said softly: "Please give me some advice, Senior Brother..."

There were not many monsters on Broken Sword Island. Gao Xian and Yin Jiuli tasted the sweetness of dual cultivation and from then on they stayed on Broken Sword Island all day long to practice dual cultivation.

In addition to the tender love between men and women, the most important thing about dual cultivation is that it allows two people to practice swordsmanship through the balance of yin and yang and purify the sword energy and sword intent.

The spiritual energy in the ancient sword abyss is rich, and it is also permeated with the sword abyss sword intent. The spiritual energy here is a bit sharp. For sword cultivators, this sharp energy is more suitable for cultivating sword qi.

However, absorbing sharp spiritual energy for a long time will cause harm to the cultivator's soul and body. Gao Xian and Yin Jiuli practiced together, one inside and one outside, the Yin-Yang sword qi against the innate Tai Chi, which can polish the sword qi and sword intention of the body and soul, and purify the sharp spiritual energy outside.

Gao Xian and Yin Jiuli could completely resolve the disadvantages and enjoy the benefits of practicing in the Ancient Sword Abyss. In this way, both of them could make rapid progress in swordsmanship.

After several months, the improvement of the Yin-Yang Sword became slower and slower, and there was still a huge gap between it and the expert level. On the other hand, the Yin-Yang Enlightenment Sutra was only a few hundred million human spiritual lights away from the master level, but the improvement speed also became very slow.

Obviously, his and Yin Jiuli's dual cultivation had reached a bottleneck. In the short term, there would not be any major breakthroughs.

Please...collect 6...9...books...!

On this day, Gao Xian decided to upgrade the Yin-Yang Enlightenment Sutra first. Over the past ten years, he has accumulated 18 billion human spiritual lights.

He won the Jiuzhou Dharma Assembly and became famous throughout the Jiuzhou. In addition to the promotion of Jubaolou, his annual income increased significantly.

Gao Xian originally wanted to leave the Human Spirit Light to the Five Qi Wheel, after all, this body-refining secret technique could most directly improve his cultivation. However, the Five Qi Wheel was of little help in sword practice.

The most important thing right now is to practice the Bipolar Yin-Yang Sword, or at least to integrate the Wuji Tianxiang Sword Sutra to lay a solid foundation for condensing the Taiyuan Shenxiang soul.

On this day, while Yin Jiuli went out to test the sword, Gao Xian opened the Fengyue Treasure Mirror and invested 500 million human spiritual lights, directly elevating the Yin-Yang Enlightenment Sutra to the master level.

In an instant, many of the essences of the Yin-Yang Enlightenment Sutra emerged in Gao Xian's sea of ​​consciousness. In a trance, he had an extremely deep understanding of this dual cultivation method, and then understood the way of the fusion of Yin and Yang...

It took a long time before Gao Xian regained consciousness. His eyes, as bright as stars, were shining with divine light. The improvement in his understanding of the Yin-Yang Sutra gave him a higher level of knowledge about the way of Yin and Yang.

This understanding allowed him to comprehend the Bipolar Yin-Yang Sword from a higher level, and some obstacles and difficulties in swordsmanship were thus resolved.

When he opened Fengyue Baojian, he saw that his proficiency in the Liangji Yin-Yang Sword had greatly improved, and he was not far from the expert level.

Gao Xian was somewhat surprised. There was indeed a connection between the Yin-Yang Enlightenment Sutra and the Polar Yin-Yang Sword. Although the connection was not very close, it was very useful.

The key is that Yin Yang Wu Zhen Jing is not a simple dual cultivation method, but a way to understand Yin Yang, reality and illusion through dual cultivation. Improving Yin Yang Wu Zhen Jing cannot directly improve cultivation, but it can improve his vision and knowledge, and improve his realm level.

With the improvement of Yin Yang Wuzhen Sutra, he not only made progress in the Bipolar Yin Yang Sword, but also made considerable progress in the Positive and Negative Five Elements Hunyuan Sutra.

Although this accumulation of knowledge cannot directly improve his cultivation, it is very important to him. It is even more important than directly improving his cultivation.

Because this improvement allows him to recognize the origin of heaven and earth and understand some of the rules of the operation of spiritual energy.

Just for this reason, it would be worthwhile to add some points to the Yin Yang Enlightenment Sutra.

Gao Xian looked at the 17 billion human spiritual lights remaining on the Fengyue Treasure Mirror and made up his mind to add all of them to the Yin-Yang Enlightenment Sutra, directly elevating this secret method to the master level.

Gao Xian's sea of ​​consciousness shook violently, and the vast and complex essence of the Yin-Yang Enlightenment Sutra gushed out like a volcano, drowning his consciousness completely... (End of this chapter)
