Facts have proved that Lu Fei's worries are completely unnecessary.

Lingyu is worthy of being the best material to assist cultivation in the legend, and after less than an hour, Lu Fei sensitively noticed that the aura emanating from Xiaoxiao's body suddenly climbed to the top.

Card rub!

Faintly, as if something was broken, the initial barrier that had plagued Xiaoxiao for a long time was shattered. Xiaoxiao has completely entered the middle stage of foundation building.

However, this is far from the end, Xiaoxiao at this time still has her eyes closed, she is trying to control the speed of spiritual power flowing into the meridians, and she does not dare to let them enter too fast, otherwise, even if she has the blood of the nine-tailed demon fox, she will definitely not be able to bear it.

It's just that in this way, most of the spiritual energy gushing out of the spirit jade will inevitably escape into the air, and Xiaoxiao can only absorb a very small part of it.

"It's such a waste!" Xiaoxiao suddenly stopped cultivating, looked at the spirit jade in her hand with a regretful expression, and then looked at Lu Fei, who was staring at her closely, her heart moved, and a bright smile suddenly bloomed at the corner of her mouth: "Feifei, let's double cultivate together!"

"Double cultivation?!"

In an instant, Lu Fei only felt a stream of blood boiling in his body, as if even his soul was floating.

What a "sexually exciting" thing this is, Lu Fei instantly thought of some pictures that were inappropriate for children, and thinking about it, he shamefully set up a small tent below.

"Phew!" Xiaoxiao secretly took a sip, her pretty face turned red, and she glanced at Lu Fei and said: "Dead Feifei, where do you want to go!" When I say double cultivation, I mean the two of us cultivating together! One yin and one yang, one man and one woman cultivating at the same time, can have the effect of promoting each other and accelerating cultivation!"

"Ahh......h......h

"Hee-hee-" Seeing Lu Fei like a frosted eggplant, Xiaoxiao couldn't help laughing, and after a while, he said: "Okay, don't grind, hurry up, I'm going to start!"

Saying that, Xiaoxiao took the initiative to put his slender jade hand into Lu Fei's hand, and his ten fingers were tightly clasped, and he firmly held the spiritual jade in the middle: "Your cultivation is higher than mine, and you will be the dominant one for a while, once the spiritual jade is activated, you will do your best to refine those spiritual qi, turn them into your own true qi, and pour them into the cyclone in your lower abdomen." ”

"Hmm!"

Lu Fei nodded, and then followed Xiaoxiao's appearance just now, and tried to slowly inject a wisp of true qi into the spirit jade.

Buzz –

With the injection of true qi, the spirit jade instantly lit up, and immediately after, Lu Fei felt a huge and pure power surging down his arm like a stormy wave.

Where did Lu Fei dare to slack off, he quickly abandoned his distracting thoughts, carefully guided this torrent, and slowly flowed into his body.

The powerful spiritual power condensed by the spirit jade over 10,000 years continued to pour into Lu Fei's body, flowing rapidly in the meridians, and finally merging into the cyclone, and after Lu Fei's tempering, it was slowly transformed into true qi that could be used by itself.

With the continuous inflow of spiritual power, the cloud-like true qi in the cyclone continued to grow, and the true qi flowing in the eight veins of the Qi Jing was also constantly increasing.

Soon, Lu Fei felt a slight feeling of swelling pain in his cyclone, as if it was filled. At this moment, Xiao Xiao suddenly grabbed his other hand, and suddenly, countless true qi surged towards Xiao Xiao's body as if they had found an outlet all of a sudden.

Faintly, the bodies of the two seemed to form a cycle, and the true qi that had been refined by Lu Fei flowed in Lu Fei's body for a circle, and then quickly merged into Xiaoxiao's body, and then ran in Xiaoxiao's body for a week, and then fed back to Lu Fei again, and so on.

And in the whole process of circulation, the true qi in the two people's bodies not only did not have the slightest loss, but showed a trend of getting stronger and stronger.

This is the benefit of double cultivation, all things negative yin and embrace yang, it is difficult to live alone yang, lonely yin is not long, only yin and yang are in line with the way of heaven.

For practitioners, the best way to combine yin and yang is undoubtedly to practice both men and women, which is the main reason why many practitioners are happy to practice both sexually.

Time passed like this, minute by minute, I don't know how long it lasted, Lu Fei felt that the true qi in his body had faintly reached a bottleneck, and an invisible barrier blocked him, making it difficult for him to strengthen his true qi.

The same situation happened to Xiaoxiao, who had just broken through the mid-stage realm of foundation building, and originally didn't expect to break through the late stage of foundation building again in a short period of time. What I didn't expect was that double cultivation had such a miraculous effect, and in just a few hours, she once again touched the barrier of the late stage of foundation building!

In the past, it was unimaginable that even if she was provided with more spirit jade, it would be impossible to jump two levels directly in such a short period of time?

Lu Fei was secretly anxious in his heart, he knew very well in his heart that he was afraid that he had touched the barrier of the Jindan period at this moment, and once he broke through this barrier, he would also officially enter the Jindan realm.

This was originally a good thing, a great good thing, and I don't know how many cultivators in ancient and modern times have been waiting for this moment after cultivating all their lives.

However, Lu Fei couldn't be happy, if other cultivators knew about it, they would definitely scold Lu Fei for being hypocritical.

Damn, I'm not happy that we have broken through in cultivation, what do you think of those of us who have practiced all our lives and have not been able to get to the Jindan period?

Lu Fei is really not hypocritical, he is just worried about one thing, the catastrophe!

The thrill of the last catastrophe, Lu Feishang still remembers it vividly, it can really be described as a life of nine deaths.

Lu Fei thought to himself, just building the foundation had already attracted such a terrifying thunder tribulation, once he entered the Jindan realm, how terrifying should the thunder tribulation be?

Of course, doesn't it mean that Lu Fei is afraid of the Thunder Tribulation, and once he cultivates, he will go against the sky, once he has the fear of the Thunder Tribulation in his heart, then how can he still practice? He is just worried that the environment he is in now is not suitable for the Tribulation, and once he crosses the Tribulation here, then he will not destroy the entire radius of dozens of miles?

The True Qi in his body obviously didn't leave much time for Lu Fei to think about it, and just when Lu Fei was worried about what to do, a strong True Qi suddenly merged into the cyclone and slammed into the barrier.

Click!

As if the glass was shattered, the barrier of the Jindan period could not resist the strong true qi of Lu Fei and Xiaoxiao after their double cultivation, and the barrier knocked out a few cracks on the spot.

Boom –

The powerful and incomparable True Qi suddenly found a breakthrough, and suddenly crashed into the barrier again, the Jindan Stage barrier collapsed in an instant, and Lu Fei suddenly opened his eyes: "Oops!"

Lu Fei almost reflexively shook off Xiaoxiao's hands and hurriedly rushed out of the door. There was a snap, and the wooden door was directly knocked out of a humanoid hole by him.

However, to Lu Fei's great surprise, the sky was clear, and there didn't seem to be any change, and there were no clouds drifting, as if nothing had happened.

"What's wrong with you?"

Xiaoxiao, who had just broken through the late stage of foundation building, hurriedly chased after him and looked at Lu Fei with a worried expression.

"This ...... How could it be? There was no thunderstorm?" Lu Fei looked at the sky with a look of surprise on his face, and muttered in a low voice.

"Thunder Tribulation?" Xiao Xiao was stunned for a moment, then covered her stomach and laughed: "Haha-Feifei, you are too narcissistic, right, the fake Dan realm wants to attract the Thunder Tribulation?

"Fake Dan?" Lu Fei glanced at Xiaoxiao in surprise and asked, "Am I not in the Jindan realm now?"

"Of course not!" Xiaoxiao nodded, and then pointed to Lu Fei's lower abdomen: "Look at your cyclone, isn't it okay to be there?" There will be no cyclone in the real Jindan period, their cyclone has evolved into a natal Jindan!"

"Besides, do you think it's so simple, and many people spend their lives in poverty, and they may not be able to succeed?"

"......Huh" Lu Fei listened to it, but instead breathed a sigh of relief and patted his chest: "That's good, that's good, scared me to death, I thought I had broken through the Jindan realm, and I was about to cross the catastrophe again!"

"Cut!" Xiaoxiao rolled her eyes speechlessly: "It's like you really survived the thunderstorm......
