Lin Bai continued to read the contents of the "Yin-Yang Longevity Scripture".
For example, some movements required the female cultivator to put her hands on the ground, lower her body, and circulate spiritual energy to accumulate the spiritual energy in her pubic bone, while maintaining a delicate balance of releasing and not releasing the spiritual energy.
Lin Bai thought for a moment and suddenly realized. "This was the so called doggy style!"
There were also some movements where the female cultivator lay on her side while the male cultivator circulated his spiritual energy and concentrated it at one point. When they had sex, the spiritual energy smoothly entered the female cultivator's body and then returned.
"Oh, this should be the spoon position." The more Lin Bai looked at it, the more curious he became. There are indeed various techniques in dual cultivation.
This way, the spiritual energy would increase a lot, and the cultivation of the cultivators would increase greatly.
There was another movement where the female cultivator sit on the male cultivator, and together they circulate their spiritual energy. Once their body temperature rose to a certain degree, they let the spiritual energy pause at the point of union.
Lin Bai looked at it for a moment and felt that this "Yin-Yang Longevity Scripture" was profound and truly extraordinary.
However, he could only see the contents of the first level now. He could not see the subsequent contents. He might have to improve his cultivation a little more before he could see them.
He planned to let Lin Yueling, rest and cultivate for some time before attempting dual cultivation with her.
During this period, although the little junior sister had not mentioned the problem of her cultivation, Lin Bai could also feel that her cultivation speed was much slower than before.
Pregnancy was highly physically demanding, especially for cultivators.
Every time she gave birth, it would take a long time for her body to recover, which greatly affected her cultivation. And the little junior sister had given birth to three children for him.
If the "Yin-Yang Longevity Scripture" could help the little junior sister improve her cultivation, it would also solve the issue of slow progress due to childbirth.
Lin Bai was eagerly anticipating the potential effects of this dual cultivation technique.
Zhao Fei'er stayed here for two days before leaving. Nothing happened between Lin Bai and her. However, before leaving, she urged Lin Bai to focus on cultivation and prepare for the upcoming inner sect assessment.
She felt that with Lin Bai's talent, passing the inner sect assessment should not be a problem.
"Don't let the little junior sister overexert herself. Giving birth affects cultivation! You should also make progress quickly. Although your cultivation speed is fast, in the path of cultivation, if you don't advance, you will regress," Zhao Fei'er advised Lin Bai before leaving.
Before leaving, Zhao Fei'er even kissed Lin Bai.
As usual, Lin Bai sent their third child to the Lin Family in the secular world. This time, he even hired more people to look after and protect their three children.
When this child with spiritual roots grew up, she could directly come to the Human Immortal Sect to cultivate. At that time, she could live with them.
After another two months, Li Yueling had completely recovered. The bodies of cultivators were different from those of mortals. They recovered very quickly after giving birth. Li Yueling looked just the same as before pregnancy.
Despite having given birth to multiple children at a young age, Lin Yueling still appeared cute, giving off a neighbor girl vibe. Her interests had shifted from reading peculiar books to studying Lin Bai.
She studied Lin Bai's habits, his physique, and everything about him.
That night, Lin Bai was prepared to try the "Yin-Yang Longevity Scripture" with Li Yueling.
"Little junior sister, I have a Dual Cultivation Technique. Do you want to cultivate together?" Lin Bai held Li Yueling and asked.
"You know dual cultivation techniques? I've been wanting to try it for a while, but I heard there might be significant side effects, and it's not very refined. It's prone to cause problems, so I never brought it up," the little junior sister expressed her regret. She had secretly looked into some dual cultivation techniques within the sect.
One had to know that she was an inner sect disciple. It was very easy for her to see some cultivation techniques.
"This cultivation method is called 'Yin Yang Longevity Scripture'. I got it by accident, so it doesn't have any side effects." Lin Bai said.
"Oh? Have you tried?" Little Junior Sister asked curiously.
"No, but that's what it says." Lin Bai said.
The system would not lie to him.
"Then try it!" The little junior sister's eyes were shining. She had always been curious about stimulating things. If it weren't for the perceived significant side effects, she would have already persuaded Lin Bai to try it.
Therefore, Lin Bai approached the little junior sister's ear and slowly told her some of the details of the cultivation in the "Yin-Yang Longevity Scripture".
Li Yueling's face turned red, and her ears turned red.
"Ah...In that case...It's a little thrilling." She whispered.
"But you like thrills, don't you?" Lin Bai said.
"Hmph." The little junior sister's eyes seemed a bit hazy.
Lin Bai was familiar with that gaze. It was the look the little junior sister had when turned on.
"Then let's do the first position first!" Lin Bai said and then waited quietly.
The little junior sister assumed the first posture as described in the "Yin-Yang Longevity Scripture".
This seductive scene immediately sparked Lin Bai's interest.
As spiritual energy flowed continuously at the junction of their bodies, Lin Bai felt that his cultivation was increasing.
This cultivation speed was much faster than the previous meditation cultivation.
On the other hand, the little junior sister, who was initially immersed in the sensation of their connection, blushed deeply. But when the spiritual energy entered her body, she couldn't help but shudder.
Before she could adjust, hot spiritual energy entered her body. This burning feeling was caused by the spiritual energy becoming incredibly active after being augmented by the Yin-Yang Longevity Scripture.
The little junior sister let out a gasp, her lower body arching upward.
She felt that the spiritual energy was flowing through her entire body, and she felt extremely comfortable. Her entire body was floating as if she was lying on a cloud. Moreover, her cultivation was also increasing.
If she continued to improve at this speed, her cultivation speed would be much faster than before. She no longer needed to worry about slowing down due to pregnancy.
She was not afraid of anything else, but she was afraid that Lin Bai's cultivation speed would be too fast. "What if he abandons me in the future?" She thought.
Now, she did not have to worry about that.
She turned around and looked at Lin Bai, who focused on his movements. Her eyes showed a mixture of confusion and admiration.
Previously, she had only seen Lin Bai as a handsome but insignificant outer sect disciple. Yet, in such a short period, Lin Bai's cultivation level had caught up to hers.
Lin Bai's current talent in cultivation was probably even better than hers.
What surprised her the most was the "Yin-Yang Longevity Scripture" that Lin Bai taught her this time.
Before practicing it, she thought it might offer some limited help, but not much. After all, Lin Bai was just an outer sect disciple who rarely ventured outside.
At first, she only agreed to try it with Lin Bai because she didn't want to dampen Lin Bai's spirits.
But she hadn't expected the results to be so remarkable. Moreover, judging from Lin Bai's appearance, it was evident that he had also made significant progress in his cultivation level.
Where did this marvelous cultivation technique come from?
