In the dark room, Xing Tian didn't mention how boring and lonely he was, in order to alleviate this feeling, he could only force himself to meditate or study the formation to pass the time.

Here, Xing Tian had no concept of time at all, and he didn't know how long it had been outside.

"Shhh

On this day, Xingtian is evolving the formation, here he is a god, anything can appear just by thinking about it. But suddenly, this sealed space actually felt cold, which was a bit incredible.

"Hey! it's getting colder!" Xing Tian didn't say that it was okay, but when he said that the coldness was even stronger, it made him a little puzzled.

Subconsciously, Xingtian changed into autumn pants! But the autumn pants, an artifact for keeping out the cold, were useless.

"Hey, it's too cold!" I don't know why the temperature is getting lower and lower, and I can't help but shiver when I'm frozen.

"This is really an evil sect, you must know that I am a spirit, a spirit! How can I feel the cold!" Xingtian couldn't stand the cold, and hurriedly put on a warm autumn pants and autumn clothes, but there was still no hair.

"Hmm!" the cold is pouring in, jumping in the day doesn't work, exercise doesn't work, playing tai chi doesn't work. Since it didn't work, he could only sit cross-legged and freeze!

But as soon as the whole person calmed down, he immediately noticed that something was wrong. Because his soul was injured, every once in a while, he would feel fatigue and then need to rest.

But this time he hadn't felt fatigue for a while, and if he had been calculated according to the previous time rules, he should have rested at least twice, but the reality was not once.

It's amazing! Xingtian came to be interested, what was the cold, so that he could be so energetic and sober.

So, Xingtian, who was idle and painful, began to study this shadowless cold.

Gradually, he found that he was really not sleepy, and he was getting more and more energetic, and the little dark room he stayed in seemed to have a glimmer of light, as if it was disappearing little by little.

......

The picture shifts to the hut of Qiankun Tu, where Shang Yang and Xing Tian are closely combined into one, and Shang Yang is the leader of this double cultivation.

At this time, the power of the earth yin accumulated in Shang Yang's body was merging and intersecting through the fusion of the two people's bodies, constantly drilling into Xingtian's body.

The power of the extreme yang, which had been nurturing for a long time, also drilled out of the dantian and into Xingtian's body. A large amount of earthly yin power caused a thin layer of ice crystals to emerge on Xingtian's body.

The power of the earth yin is not only affected by the body, but also by the soul of Xingtian, which is why the little black house is getting colder and colder.

The best state of double cultivation is that the woman integrates all the yin energy into the male body, and then the man sends his extreme yang power into the female body, and then the yin and yang of the two sides merge with each other, and the mana of each other merges with each other to form a larger cycle, so that the absorption of aura is not one plus one equals two, but one plus one is greater than two.

However, Yin Qi is different from the power of extreme Yang, it is distributed all over the female body, and each time it needs to last for a long time. And the male outburst only needs to send the power of the extreme yang into the female body at the last moment.

As a result, each double practice lasts for a long time, with the shortest being three or four days at the shortest and more than half a month.

Double cultivation is not possible at any time, but requires both parties to accumulate each other, accumulating the power of yin and yang, so as to have the greatest harvest.

If you don't usually accumulate it, it is at most a mutual spiritual fusion, accompanied by the creation of the next generation.

This is Shang Yang's first double cultivation, and it is also the time when her earthly yin power is at its strongest. Just sending the power of the earth yin to the body of Xingtian lasted for half a month.

During this period, the power of extreme yang from Shang Yang's body had been refined by Xingtian's dantian, which strengthened his martial arts golden pill.

The mana and internal forces of the two have been linked, and at this time, a large cycle has been formed, which is constantly circulating along the bodies of the two.

Although Xingtian is in the middle stage of the innate realm, the internal qi stored in the dantian is not small. Coupled with the magic of the martial arts ceremony, Shang Yang is the one who has gained the most.

"Boom, boom!

On the third day of the two of them's double cultivation, Shang Yang, who cultivated as the highest, was the first to embark on a breakthrough journey, and she had been stuck in the middle of the antenna, and successfully broke the shackles and reached the late stage of the Heavenly Immortals.

However, this breakthrough is not over yet, with the blessing of Xingtian's profound internal qi and a large amount of spiritual energy, Shang Yang's cultivation has broken through one after another.

On the fifth day, she broke through the peak of the Heavenly Immortals, and her physical body had grown fully under the dual tempering of spiritual energy and internal qi.

On the tenth day, Shang Yang broke through again, and this time she crossed the steps of Heavenly Immortals and Xuan Immortals, and advanced to the early stage of Xuan Immortals.

And this time, not long after Shang Yang's breakthrough, Xingtian also broke through, and his breakthrough was very low-key, only reaching the late stage of the innate realm.

On the fifteenth day, all the power of the earth yin in Shang Yang's body poured into Xingtian's body. And Xingtian also returned all the extreme yang power he contained at that moment.

Shang Yang in cultivation only felt a heat explode in his lower abdomen. Then, the aura loophole began to rotate, and the aura converged in a more violent posture, constantly being pulled into the body by the suction on the two of them.

Double cultivation has reached its peak, this is the last point that can make a breakthrough in the process of double cultivation, and it is also the stage where the whole process of double cultivation breaks through the rage.

A large amount of aura and yin and yang blended, and the power formed exploded in the bodies of the two.

The two of them both broke through at this moment, and Shang Yang, who was originally at the critical point again, did not break through a small realm this time, but directly rushed to the late stage of Xuan Xian, and was only one step away from the peak of Xuan Xian.

As for Xingtian, the power of the extreme yang from Shang Yang's body and the qi of the earth yin were perfectly fused, and he actually formed a rotating yin and yang fish in his dantian, and his cultivation rose all the way from the late stage of the innate realm!

The peak of the late stage of the Innate Realm!

The pinnacle of the Innate Realm!

The early stage of the Martial Spirit Realm!

At the peak of the early stage of the Martial Soul Realm!Finally, the cultivation stayed in the middle of the Martial Soul Realm.

After the crazy breakthrough, the two did not wake up for the first time, but with the help of double cultivation, it took three days to stabilize the breakthrough cultivation.

Shang Yang was the first to wake up, opened her eyes, she felt the strangeness of her lower body, and then saw the embarrassing movements, her face was about to burn.

The double cultivation has ended, and as for the healing effect, she doesn't need to worry about it. If Xingtian's soul was not repaired, his cultivation would not be able to improve, and it would only be a matter of time before Xingtian woke up.

Just when Shang Yang frowned, he was about to get off Xingtian's body.

But just as soon as she moved, she felt her waist being hugged. When I looked up, I don't know when Xingtian had come to his senses.

"Ahh

Looking at that smiling face, Shang Yang was shy and wanted to dodge, but he couldn't get out of it at all when he was hugged by Xingtian's strong arms.

"What are you running, what are you running! After the double cultivation, shouldn't we get down to business? Xing Tian smiled evilly and blinked, his big hand swept over Shang Yang's pride, and at the same time straightened his waist.

"Hmm!" Xingtian's sneak attack made Shang Yang ashamed, and just as he wanted to open his mouth to refuse, Xingtian's big mouth was blocked.

"Haha! Since it's in my hands, don't even think about running!" After speaking, Xing Tian turned over with a wicked smile, and the two sides changed positions and started another struggle.

"Hmph, you don't want to ask, when did my merchant sheep escape, isn't it just three hundred rounds of battle? Who is afraid of whom!"
