As the information echoed in his mind, Lin Bai suddenly felt a mysterious energy flooding his body once again, creating an inexplicable sensation.
At the same time, he felt his body becoming extremely relaxed, and the spiritual energy within his body became active. This mysterious power was actually the overall improvement of his aptitude after the increase in lifespan.
Lin Bai felt that his cultivation was increasing at a perceivable speed, and the aura on his body had become a little strange. The fluctuations produced when one's lifespan increased were very special.
Lin Bai's appearance became a little younger. Every time his lifespan increased, it would bring about these strange changes.
At this moment, Li Yueling and Zhao Fei'er's gazes focused on the baby. They had not noticed the change in Lin Bai.
Lin Bai's cultivation level continued to increase.
Most cultivators, except for those who were especially talented in cultivation, would progress very slowly.
The most representative example was the old man working in the spirit field. His vitality was almost depleted, and he was still at the first level of Qi Refinement Stage.
For those with slightly better talent, if they wanted to improve their cultivation, their improvement would be calculated on a yearly basis.
However, Lin Bai's current cultivation increased in seconds.
Many people who want to progress from the fifth level of Qi Refinement may take several years or even more than a decade to make any advancement.
For example, Zhao Fei'er. When Lin Bai met her, she was at the sixth level. Now, she was still at the sixth level. It was too difficult for her to improve.
It was because of this bottleneck that Zhao Feier took on numerous missions to earn resources and used spirit stones to purchase pills that might help improve her cultivation.
It could be said that ever since Zhao Fei'er met Lin Bai, she had been continuously doing missions. The rest of her time was in seclusion cultivating.
As Lin Bai's cultivation increased, the vigor of his body also increased. He finally attracted the attention of Zhao Fei'er and Li Yueling.
"Lin Bai, what's wrong?" Li Yueling looked at Lin Bai.
Li Yueling had just given birth, and her body was still a bit weak. However, when she realized that something was wrong with Lin Bai, she was a little anxious.
Zhao Fei'er also looked at Lin Bai, but after sensing for a while, she said to the little junior sister, "Don't worry, he seems to have broken through."
At the same time, Zhao Fei'er was shocked. She felt that Lin Bai was too monstrous. She thought, "What kind of talent was this? Had a new baby, and then your cultivation will soar?"
In the past, there were also some rumors, such as some cultivators entering a state of enlightenment, and then after the enlightenment, their cultivation suddenly increased greatly.
"Could it be that Lin Bai had an enlightenment because of the new baby?" Zhao Fei'er felt that this matter was extremely ridiculous. In the end, she felt that it might be a coincidence. Perhaps Lin Bai had cultivated to a certain extent, and then with the birth of a child with spiritual roots, he was excited and entered a certain state, which made his cultivation level increase.
Soon after, Zhao Fei'er felt a twinge of sadness in her heart. She had been tirelessly taking on missions and cultivating day and night just to improve her cultivation level by a little bit.
However, despite her efforts, her cultivation level had only improved by a small margin.
But now, Lin Bai's overwhelming aura indicated that his progress was more than just a slight improvement. He might have even directly entered the next level of the Qi Refinement Stage.
But she found it hard to believe. When she first met Lin Bai, he was at the fifth level of Qi Refinement. How could he progress so quickly to the next level?
It took her almost six years to go from the fifth level of Qi Refinement to the sixth level of Qi Refinement. Her aptitude was average and many spent about the same amount of time as her.
Just then, Lin Bai's aura suddenly surged again.
"6th level of the Qi Refinement Stage!" Lin Bai felt that his cultivation was still increasing.
Entering the sixth level of Qi Refinement, Lin Bai felt that the energy in his body had become much stronger than before, and his physical strength had also increased significantly.
The spiritual energy in his body was still very active.
At this moment, Li Yueling also discovered that Lin Bai's cultivation had increased to the sixth level of the Qi Refinement stage. She felt very happy.
Her talent was very excellent, and she did not know the hardship to improve as Zhao Fei'er did. Her cultivation might have already soared higher if it weren't for the children she had borne for Lin Bai.
Zhao Feier, on the other hand, couldn't remain calm. She watched as Lin Bai progressed from the fifth to the sixth level of Qi Refinement, and his cultivation speed was too astonishing.
Lin Bai's cultivation level continued to improve slightly, but finally stopped advancing. The strange fluctuations in his body also disappeared.
He smiled and held the baby. He did not know what the luck of the Lin Family would do, but he felt that it was very important.
However, he believed that the improvement in the Lin family's luck would have a profound impact in the future. With the increase in descendants, his family would definitely flourish.
This was the first child to have spiritual roots, but she would not be the last. From now on, his family could be considered a cultivation family.
Lin Bai named this child Lin Yuxian, hoping that she would be successful in cultivation in the future.
Then, he started to check the cultivation technique that he had obtained from the system.
The "Yin-Yang Longevity Scripture" was a dual cultivation technique. It required the participation of both men and women. There was no limit to the number of people practicing it, with a minimum requirement of two individuals.
Information about the "Yin-Yang Longevity Scripture" kept flashing through Lin Bai's mind. When cultivating the Yin-Yang Longevity Scripture, men and women needed to engage in Yin-Yang intercourse.
In fact, there were some dual cultivation techniques in the sect as well, but they were rarely used. Only couples might try them. However, most dual cultivation techniques tended to only benefit one party and were not considered orthodox. Sometimes, it gave people the feeling of using yin to supplement yang or using yang to supplement yin.
Moreover, many dual cultivation techniques had flaws. While they improved cultivation levels, they actually caused certain damage to the body, which could affect either the female cultivator or the male cultivator.
However, the "Yin-Yang Longevity Scripture" came from the system, so it did not have such problems. It had no harmful effects on the practitioners and could help both parties improve their cultivation level.
With the "Yin-Yang Longevity Scripture", there was no need for traditional meditation cultivation. Dual cultivation with this technique was sufficient.
Lin Bai continued to read the "Yin-Yang Longevity Scripture" in his mind. This book was divided into nine levels, and he had to start from the first level. With practice, the cultivation level would gradually increase.
Currently, he could only access the content of the first level.
The content of this level focused on the exchange of energy and the harmonization when male and female cultivators engaged in intimate moments, benefiting each other's cultivation.
Many aspects of the content left Lin Bai greatly astonished. Even without dual cultivation, the information within could unravel many of his cultivation doubts.
There were also many scenes in the "Yin-Yang Longevity Scripture", and the movements were very strange.
