Jumping up, jumping several feet high, Luo Xu jumped on his feet and stepped on the bamboo branches and bamboo leaves to fly, the speed was much faster than walking through the bamboo forest, and the field of vision was broader, which was conducive to him looking for waterfalls.

The cave of the fox demon Ziqing was hidden in the depths of the bamboo sea, and Luo Xu flew for a while before he heard the sound of water, and flew away following the sound of the water, and sure enough, he saw a waterfall.

"This is it!"

Luo Xu quickly rushed towards the waterfall, passing through the turbulent water, and behind him was another world.

The cave behind the waterfall was completely different from what he had imagined, not a barren and chaotic cave, but a beautiful new world of birds and flowers.

This cave is extremely open, with dense flowers and plants, white birds, stone benches, stone tables, and even a swing made of flowers and vines.

"Ziqing, are you there? I'm here. ”

Luo Xu stood outside the door and shouted, although he and Ziqing have become Taoist couples, this cave is not owned by him, and it is not easy for him to break in.

A white light flashed, and then a snow-white figure appeared in front of Luo Xu.

"Luo Xu, you can be counted as here, the people who are waiting are kind and anxious. After all, Ziqing is a fox demon, so she naturally has a charm, and she snorted angrily at Luo Xu.

Luo Xu smiled: "I'm not here." How about it, hurry up and cultivate the Rejuvenation Technique, right?"

Ziqing nodded and asked, "Have you studied the mental method?"

Luo Xu said: "I have already studied it, but I don't know one thing, why does this rejuvenation recipe need to be cultivated by both men and women?"

Zi Qing didn't answer and asked, "Luo Xu, do you know how heaven and earth were formed?"

Luo Xu shook his head, this question is not easy to answer.

Zi Qing continued: "The formation of heaven and earth is due to the convergence and fusion of yin and yang. The sky is yang, the earth is yin, the sun is yang, the moon is yin, fire is yang, water is yin, men are yang, and women are yin.

The solitary yin does not grow, and the solitary yang does not grow. If the sun shines on the earth forever, how long can all things live? Yin and yang seem to be a pair of contradictions, but in fact they are the avenue of heaven, and they are rooted in each other, and only when yin and yang are harmonized can all things survive and develop in harmony.

Rejuvenation is based on the yin and yang mutual roots and create a zào exercises, I practice alone, although I can achieve a small success, but after all, it is inevitable to fall into the 'lonely yin and no birth' dilemma, you need to help each other with your yin and yang, in order to be able to practice the rejuvenation of the perfect state. ”

The theory of yin and yang, Luo Xu had already heard of it, and after listening to Ziqing's explanation, he knew why the rejuvenation technique needed to be cultivated by both men and women. Yin and yang are combined, and all things are rejuvenated, which is the true meaning of rejuvenation throughout.

"Are you ready?" Ziqing asked with a smile.

Luo Xu nodded.

Zi Qing took a step forward, grabbed his hands, and the two of them jumped and landed on the green vine in the middle of the flower.

The two of them pressed their palms against each other, and Ziqing's voice echoed in Luo Xu's divine sense.

"Keep your mind one, and not be moved by external objects, from now on, there should be only me in your world. I'll take you to feel yin and yang......"

Luo Xu closed his eyes, and under Ziqing's guidance, he sensed the yin and yang qi in his body. Perhaps because he had cultivated the Nine Heavens Divine Fire Technique, the yang energy in his body was much stronger than that of ordinary people.

Zi Qing detected this powerful yang energy, and her heart was ecstatic. The stronger the other party's yang energy, after blending with her yin energy, more yin energy can be generated, and what it brings to her is the improvement of cultivation.

Under Ziqing's guidance, Luo Xu input the yang qi in his body into Ziqing's body, and at the same time, Ziqing also imported the yin qi in his body into Luo Xu's meridians.

The two yin and yang are blended, and their roots are mutual, but they are not conserved, sometimes the yin is strong, sometimes the yang is strong, and it is precisely because of this imbalance that the yin and yang are mutually rooted and mutually reinforcing. When the yin is strong, the yang energy will quickly catch up and surpass, and once the yang energy has the upper hand, the yin energy will immediately become stronger, catching up with and surpassing the yang energy.

It is this balance in the imbalance that causes the yin and yang qi of both of them to continue to grow. The same is true of all things in the world, prosperity and decline, or not, it is all a process, rise and fall, death and prosperity, there is always a reincarnation.

The biggest surprise is the demon fox Ziqing, she used to practice this rejuvenation technique alone, although she has achieved a little success, but after all, what she learned is only the skin. As soon as she practiced with Luo Xu today, she felt as if she had entered a new world, and under the mutual rise of yin and yang, her Taoism was constantly improving.

I don't know how long it took for the two to call it a day. Open your eyes and smile at each other. After this double cultivation, both of them felt the improvement of their cultivation.

Luo Xu carried the rejuvenation formula, and a white light the size of a bean grain appeared from his fingertips, and he flicked the white light onto a flower bud, and the flower bud instantly bloomed into a flower.

It was getting late, and soon after Ziqing went out, she brought some fruit back.

"You usually eat these?" Luo Xu asked with a smile.

"Hmm. Taste one, it's sweet. Ziqing said with a smile.

Luo Xu was not happy without meat, thinking that there was something delicious about the wild fruit, so he took the fruit handed over by Ziqing and took a bite, the honey in the flesh exploded in his mouth, and immediately made him put away the idea just now, and ate many in a row.

"Luo Xu, the yang energy in your body is very strong and domineering, I think this has something to do with your cultivation, right?"

When cultivating during the day, Zi Qing felt it.

Luo Xu nodded, Zi Qing was his Taoist companion, and he didn't hide it, "I can't hide it, the exercises I practice require constant absorption of the fire element, so the yang energy is relatively strong." ”

Ziqing said: "You are fortunate to have met me, otherwise one day, you will encounter a bottleneck that is difficult to break through." ”

"Why do you say that?" Luo Xu asked curiously.

Ziqing said: "It's still the same sentence, the lonely yin is not born, and the solitary yang is not long." As your cultivation improves, you will definitely need to absorb more and more fire elements, and the yang energy in your body will be too strong, crowding out the yin energy, and only the yang energy will remain, and then you will absorb the fire element, which will not only be difficult, but also likely to lead you to go mad and burn yourself to death. ”

Luo Xu was shocked into a cold sweat when he heard this, what Ziqing said was not alarmist. He learned from Ling'er that he was as strong as the Ziji True Person, and he had not been able to cultivate the Nine Heavens Divine Fire Technique to the extreme, and he could not withstand the heavenly thunder and earth fire when he crossed the tribulation. Ziji Zhenren's failure to cultivate the Nine Heavens Divine Fire Technique to perfection was probably due to the misunderstanding of simply absorbing the fire element.

"Thanks for the reminder. ”

Ziqing handed him a bottle of rain dew, "Drink some water, this is not ordinary water, it is all the essence of heaven and earth." ”

Luo Xu took a sip and felt the difference of this water, but unfortunately he hadn't tasted it yet, and a bottle of rain and dew had already been drunk.
