These liquids condensed with innate qi will gradually solidify, and after an hour, they will completely turn into solid, and although they can be reversed into a gaseous state with secret techniques, according to the secret arts, he must build a wall-like barrier before it completely solidifies, so as to separate the sea of qi. Because the dantian space is shaped like a sphere, a total of five barriers with the central axis as the common starting point are needed to complete the fifth division of the sea of qi.

Therefore, the problem in front of He Lingfeng was that within an hour, he had to condense enough liquid innate qi and turn it into a strong enough barrier. Later, after a total of five barriers were built in this way, the five small dantian spaces separated by this must also be kept the same size.

It was a matter of cultivation in the future, and He Lingfeng knew that this matter could not be tricked, and every step must be completed in strict accordance with the records of the secret arts. Otherwise, once the separation barrier is damaged during cultivation in the future, causing the spiritual qi of the five elements to be absorbed to clash with each other, or the size of the separated space is different, resulting in the imbalance of the five elements when the five qi are finally fused, then he will reap the consequences, at least the spiritual root will be destroyed, and at the worst the body will explode and die.

Thinking of this, He Lingfeng felt that it was urgent to use secret techniques to separate the sea of qi, and it was better to work slowly and carefully. Therefore, he decided that this is the end of the day, and he wants to rest well and wait until he has enough energy to move on to the next step.

He Lingfeng walked out of the secret room space of Tianyi Zhenren and went back to the house to rest. Xu was tired, he slept very soundly that night, and when he woke up the next day, he suddenly felt refreshed, and he devoted himself to cultivation again.

He Lingfeng entered the secret room space of Tianyi Zhenren and came to that small world to continue to cultivate the secret arts. On this day, he planned to try to build a barrier separating the dantian first, and then move on to the next step.

He Lingfeng guided the innate qi in his body from the meridians to flow to the dantian, and then immersed his mind in the dantian, carefully compressing the condensed innate qi with secret techniques, and finally condensed the droplets at the bottom of the dantian. It took him more than half an hour, and the method he had mastered the previous day could be able to condense a small cloud of syrup-like innate qi the size of a walnut.

Next, he had to control his mind to slowly pull this viscous liquid into sheets of uniform thickness, starting from the central axis, so that it would connect with the inner wall of the dantian to form a barrier to separate the sea of qi.

At first, he could only slightly lift a part of the viscous liquid with his mind, and he couldn't fix it like building a wall, often just forming a sheet and standing up at the bottom of the dantian space, and the next moment it was staggering back and forth, paralyzed into mud. After tossing the tea kung fu to keep it in the shape of the wall, after that, it took him more than a stick of incense to build all the condensed liquid into a wall-like sheet, and keep it undeformed until it completely solidified, but the barrier was still quite far from the top of the inner wall of the dantian, almost only about half of the complete barrier. Obviously, the liquid innate qi he condensed was completely insufficient.

It seems that it is necessary to speed up the efficiency of the convergence and condensation of innate qi. So, with the belief that practice makes perfect, he began to repeat the previous day's cultivation again. After spending most of the day on this item, he was finally able to condense enough viscous liquid to build a complete barrier in half an hour. But he couldn't build the barrier fast enough, and he could only build half of it for an hour before the viscous liquid solidified.

He shook his head, smiled bitterly, and thought to himself, I don't look like a cultivator who doesn't eat fireworks in the world, I don't have any fairy ethereal feeling, but like a plasterer who builds walls in the mortal world, or a craftsman who burns pottery and porcelain is pulling embryos.

However, he was just having fun and laughing at himself. After He Lingfeng rested for a while, he began to practice building barriers again, in order to speed up.

On this day, he practiced until the time had passed, so that he could ensure that he could not only condense enough liquid innate qi in one hour, but also complete the construction of a complete barrier.

He took a long breath and went back to rest in the secret room.

On the third day, He Lingfeng didn't take long to build all the five barriers, but when he used the detection method described in the secret technique to determine the size of the five parts of the dantian space, he found that the gap between them was too large.

However, it is not easy to separate the five parts of the dantian space to the same size, if it is outside the body, there are weights and measures that can be used as a reference to assist in separation. But in the dantian, there is no other way but to use a cumbersome method called the 'filling method' mentioned in the secret arts.

The specific content is to first condense the innate qi droplets to completely fill the dantian space, and write down the total number of condensed droplets, that is, the number of A, and then build a barrier to record the number of droplets required, that is, the number of B. Then, subtract five times the number B from the number A to obtain the number C, and one-fifth of the number C, that is, the number D, is the standard volume of each dantian space after separation. At this point, as long as the second barrier is constructed to connect with the first, the first sea of gas separation is separated, and the droplets are poured into it, and adjusted according to the number, until the number of droplets just enough to hold the number of droplets is considered to complete the construction of a sub-space. This step is repeated until all five spaces have been constructed.

"Unexpectedly, the predecessor who founded this method was still a proficient person in mathematics and physics. He Lingfeng grinned when he first saw this method, and was troubled by its cumbersomeness, but after thinking about it, if there was no such method, wouldn't it be all about luck to try repeatedly, and it would not be until the Year of the Monkey and the Horse Moon that a fifth-equal dantian space could be formed? Maybe there would be no hope in this life.

So, in the next few days, He Lingfeng used this stupid method and the only way to try to divide the dantian qi sea into five equal parts, and finally completed the complete separation of the qi sea around noon on the ninth day when he began to cultivate the secret technique.

"It's really tiring for me, if it weren't for the "Five Elements True Scripture" but a fragment, I would have to throw away this secret technique...... Alas, I didn't expect that this Five Elements Spirit Root was so troublesome to cultivate, this is the preparation stage ahead, and there are still five Five Elements Single Attribute Exercises waiting for me to comprehend and cultivate......" He Lingfeng finished cultivating the secret technique, and after returning to his residence, he directly spread it on the bed with large characters on his back and began to chatter.

Thinking that there were still five exercises to be cultivated in the future, He Lingfeng's head suddenly became big, and he simply postponed it to the next day to deal with it.

"It's better to go and play with Feng Ling'er", He Lingfeng lay down for a while, but such a thought came to his mind. It's been a long time since I've seen this little girl, and he misses Feng Ling'er a lot.

So, he made up his mind immediately, and he didn't drag the mud and water, a carp stiffened, got up from the bed decisively, and went to the mirror to tidy up his appearance, and then ran to find Feng Ling'er with anticipation.

After he found Feng Ling'er, the two talked and laughed for a while. After that, Feng Ling'er took him to his brother Feng Wuchen, and the three of them drank vegetarian wine and fresh vegetables under the shade of the trees in the courtyard, talked and laughed, and were so happy. He Lingfeng's fatigue from cultivating for days also dissipated a lot, and at the same time, he felt that his relationship with Feng Wuchen's brother and sister was getting closer and closer.

But in the midst of talking and laughing, He Lingfeng was surprised to learn that this delicious fresh vegetable dish was cooked by Feng Wuchen himself. He couldn't associate that usually chic and arrogant image with the smoke and fire in the kitchen. Moreover, when he saw Feng Wuchen's brothers and sisters entering the kitchen together, he thought that Feng Ling'er was in charge, and Feng Wuchen was just doing it.

At this moment, he looked at Feng Ling'er with a puzzled expression, and asked with a clueless smile, "I thought you did it, it seems that you don't know how to cook?"

Feng Ling'er blushed, snorted slightly angrily, and said, "What's wrong with not being able to cook?" If you want to take care of it, girls have to cook and embroider, husband and children, I'm not a mortal person...... "As she spoke, her voice became quieter. Then she changed her direction and said, "My brother likes to do what he likes, and even when he eats, he often does it himself to satisfy his tastes." I like to do what I like, but I'm not very particular about the minutiae of my meals......"
