"Say!" Wang Yuyan couldn't tell whether she was happy or disappointed.

"When your master cultivates the Jade Maiden Heart Sutra at the top, you are required to practice without clothes, and this double cultivation method can also be so fast, as long as the hands of men and women are in contact and they are not wearing clothes, they can do it. Li Fei said.

"Ah, I thought!" Wang Yuyan stopped talking, afraid of leaking her mouth.

Li Fei laughed, he remembered the sneaky laughter and some words of some girls who had peeked at Dongying's romance movies on Earth.

Wang Yuyan must have studied the double cultivation method often.

"Come on, try it, there is a curtain in front of us, let's strip naked and practice! First of all, let's say okay, don't peek at me, I'm a natural god, I can't look at it, I will die when I see it!" Li Fei Zhengse said.

He was deliberately funny, otherwise Wang Yuyan would be shy, and he wanted to lower her shyness.

"Okay, we have to practice as soon as possible and defeat Senior Sister, anyway, if she breaks this starry sky array, she won't be able to open this coffin quickly, we have time. Wang Yuyan said.

Li Feixin, there are many organs here that are very complicated, and Lin Chaoying will still have something to protect his disciples.

The Jade Maiden Heart Sutra double cultivation is similar to single cultivation, the difference is that after running the true element in her own body, she has to transport her own true essence to the other party's body to run, and the other party has to cooperate at the moment, so that each other goes back and forth, and the true yuan that each goes out returns to their respective bodies.

In this way, the true element has obtained the comprehensive evolution of yin and yang, and it can exert several times to dozens of times the power of the previous true element alone.

Li Fei has memorized those meridian operation charts, and can roughly judge the location of the other party's meridians.

The two of them began.

A curtain was in the middle of them, and they each undressed himself, then his hand stretched out and began to exercise.

At the moment of the great enemy, Li Fei didn't have the heart to figure out how beautiful Wang Yuyan's body was, but just concentrated on meditating on those meridian diagrams and operation methods.

Over there, Wang Yuyan was actually twisted in her heart, but when she thought of the moment of life and death, that shyness was overcome, she undressed, stretched out her palm, and began to teach Li Fei to run Zhenyuan.

Zhenyuan first started from Wang Yuyan, then she ran to various special meridians, and then walked into Li Fei's palm, and Li Fei began to run Wang Yuyan's true yuan in his own meridians.

As soon as the true element of pure yin entered his body, Li Fei felt a burst of coolness, all the dryness of his previous cultivation was neutralized, his true yuan was purer, and with her, it was running in his own meridians, and many meridian acupuncture points were shining brightly.

This is a sign that the function point is opened, and after it is opened, all kinds of power use abilities, and even immortal paths, can be greatly improved.

Eighteen special meridians and one hundred and eight special acupuncture points gradually opened, and Li Fei felt that the biggest obstacle to his general's level improvement had been cleared.

He was overjoyed.

For Wang Yuyan, her pure yin true yuan entered Li Fei's body, and she also received the blessing of Li Fei's pure yang body, and there was a qualitative change all of a sudden, and the peaceful effect of yin and yang was reflected, and that power suddenly became more than several times stronger, she was overjoyed, it turned out to be like this.

Entering Li Fei's dantian, this true yuan gained more pure yang power, boomed, and swelled up all of a sudden.

It's like a small river suddenly becoming a big river.

Li Fei worked hard to control and let these true elements help him even more.

Then, Wang Yuyan's true yuan went back, and his true yuan also passed.

Then Li Fei felt that his true yuan was walking in Wang Yuyan's body, and the original Duyang obtained the purification of the pure yin body, and suddenly became more pure and powerful, and obtained the energy of the acupuncture points that Wang Yuyan had opened up, and the true yuan entered her dantian, and this true yuan was purified by the pure yin body of the pure yin body to become more pure, and it also became bigger and bigger.

This principle is the same as Wang Yuyan's true yuan in his body.

Their true essence has begun to become like a great river, and if they continue to cultivate, they will become the sea just around the corner.

If that's the case, their inner body is the sea of true elements.

In that case, whether it is martial arts or becoming an immortal, it will have great results.

What's more, Li Fei still has the colorful stone in his body, and the light emitted by the stone illuminates Wang Yuyan's true yuan, and also illuminates Wang Yuyan's jade body, Wang Yuyan feels that she is more thorough about the way of heaven and earth, martial arts, and immortals, and her energy is more powerful.

......

They continued to operate according to the secret method.

They followed the Jade Maiden's Heart Sutra double cultivation secret method, step by step, the first layer, the second layer, the third layer, and the fourth layer, and they all passed these realms smoothly.

"Master said, it's dangerous to be above the fifth floor, don't we continue?" Wang Yuyan spoke.

"Go on, the person outside is almost recovering!" Li Fei looked outside the coffin, and a thick white mist emitted from Shao Si's head, and it was estimated that when the white mist dissipated, she was about to recover.

"Okay!" Wang Yuyan also knew this.

They continue to run.

It's just that suddenly, they run to a critical node.

That was an obstacle for Wang Yuyan, a key obstacle to her realm ascension, and Zhenyuan had never been able to get through there.

Maybe it's because the strength of this combination of yin and yang is not enough, and the power is not grand enough, and it can't break through there.

Wang Yuyan kept being hit by luck, but it never worked.

At this time, if they don't rush over, the true yuan will fill Wang Yuyan's body, and then pour it like Li Fei's body, these true yuan will run around their whole body, and they will go crazy, paralyzed or directly die with broken meridians.

The situation was critical, Li Fei felt Wang Yuyan's pain, and he also felt very painful.

What went wrong?

Could it be that the strength of the yin and yang combined with this palm is not enough?

But can there be anything else?

Legend has it that men and women are intercourse, and they can't take advantage of others' danger, so it's really not good to do this at this time.

The blue tendons on Li Fei's face came out, and the true yuan overflowed in Wang Yuyan's body, and it will also overflow his body, and after it overflows, the two meridians of their two will burst.

Li Fei couldn't care about it, he hurriedly asked the system.

"You are smart yourself, and this double cultivation has to be done by a man and a woman, so you can have it. The system said directly.

"If you don't intersect, is there a way?" asked Li Fei.

"Hmph, I don't know, there's a second way, but I'm not responsible if I can't get by!" the system said.

Li Fei was stunned for a moment, what is the way, he knows that the system will not say it anymore, it has to enlighten itself.

Li Fei seemed to understand, he pulled the curtain over, wow, Wang Yuyan's beautiful body was in front of him.

But he didn't have time to appreciate it.

Wang Yuyan was already very uncomfortable, and when she saw him suddenly open the curtain, she was even more anxious, but Wang Yuyan was very smart, she knew that Li Fei was trying to find a way, otherwise she would be in a hurry, and her meridians would burst and die immediately.

And she already has a strong impression of Li Fei, and she will accept what Li Fei really treats her.

It's just that her beautiful eyes are still panicked.

Li Fei didn't care about it so much, his hand was still in Wang Yuyan's hand, and his mouth suddenly kissed it.

He kissed her tightly on the mouth, like a sucker, and then pressed his tongue against Wang Yuyan's tongue.

Wang Yuyan's eyes widened, not knowing what he was going to do, she was ashamed and anxious.
