Although there is no mutual erosion and assimilation between the two aura, the two auras run in the same meridians at the same time, and the running speed of the two auras is much slower, and the body also feels very uncomfortable under the mutual squeezing.

If it continues like this, not only will it not be able to give full play to the advantages brought by dual cultivation, but it will drag down the operation and use of the aura because of the two auras.

It seems a bit counterproductive.

Looking at Chen Ling's frowning brows, Old Man Ge seemed to understand his feelings at this time.

"Do you feel that the two auras are running in the body, so that the auras squeeze each other can't exert the speed that they should have, and it also makes the body very uncomfortable?" Old man Ge said: "I was in the same situation as you at the beginning, and this is also something that can't be helped. ”

"How did you overcome it?" Chen Ling finally opened his eyes and asked.

"There is nothing you can do but strengthen the exercise, let the body get used to the effects of the superposition of the two aura, and it will be much better over time, no matter what, the benefits of the two auras running each other are always much more than the disadvantages. ”

Chen Ling nodded, a smile on his face.

Re-learning the previous cultivation method, the operation of the two auras together is equivalent to doubling the power stored in the body, even if it is a little difficult to use it now, but it is completely possible to continue fighting with another aura after one aura is exhausted, this kind of unparalleled advantage cannot be offset by any disadvantage, not to mention that it is not too much of a disadvantage, at most it is not as satisfactory as he imagined.

"There's another question I'll ask you, so I'll answer you first. Old Man Ge said: "The filtered polluting elements will be fused to form the aura that forms the filter, and you don't have to worry about your body being affected when you reabsorb these aura." Because the aura in the Spirit Diamond we absorb has these elements, and they will not affect the body after they are fused into the aura. Rest assured. ”

"I see. Is there anything else I need to pay attention to?" asked Chen Ling.

"The rest is nothing worth noting, the most fundamental problem of re-cultivation is that you need to exude vitality and break and then stand up, once you complete this other thing, it is really not worth mentioning for those of us who came over at that time. Old man Ge stood up from the ground and said, "You are not well yet, rest here first, and tell me when you want to leave." Don't forget what I told you. ”

"Don't worry, I don't promise others easily, but if I do, I will definitely not break my promise. ”

"I believe in you. I really went to collect medicine, and you have eaten up all the good medicine these days. ”

Chen Ling smiled and closed his eyes.

He was not in a hurry to leave Old Man Ge's place, firstly, his current body had not fully recovered, and secondly, he had encountered some problems in re-cultivation, he just needed such a place of pure cultivation to think about these problems, if it could be solved, it would be the best.

Who is Chen Ling?

Eight thousand years ago, at the top of the Nine Realms, he was a genius boy. Even they all praised him as a genius of the Nine Realms Mountain before he had a bad relationship with the gods, and for a genius like her, he couldn't tolerate a lack of his cultivation skills.

Old Man Ge let him re-learn the old cultivation exercises, but Old Man Ge had two problems in this set of exercises, which were not big or small, but they were unbearable for him.

One is that the Heaven and Earth Spiritual Qi needs the polluting elements in the filter before it enters the Qi Sea, which obviously slows down the absorption of the Spiritual Qi.

The second is the problem just now, the two auras run in the body at the same time, occupying the same running line with each other, and the original one-way road has become the current two-way road. Crowding is inevitable.

Although Chen Ling's previous idea was correct, he could use a single aura to fight. One is used and the other is used, but this choice cuts off the possibility of the two auras being cast together.

For a genius, any possibility must be mastered.

One more possibility is one more way to fight, and one more way to fight is one more chance to win by surprise.

Chen Ling is by no means a person who is willing to compromise.

First of all, the first question, the filtration speed of the two barriers is obviously limited and slow, so what about adding another barrier?

Chen Ling used his mind to operate the aura in his body. Trying to increase the third barrier and speed up the filtration of the aura, but after actually doing it, Chen Ling understood why Old Man Ge asked him to set up two barriers instead of three, four, or even more barriers.

Adding one barrier may seem simple, but adding one barrier requires a lot more ideas to maintain the stability of the three barriers, and the idea of using it for other things is weaker. For example, the absorption rate of aura has slowed down, and the absorption of aura has also decreased.

It's clear that this is a trade-off process.

Presumably, Old Man Ge himself also went through a long period of experiments before finally determining that the two barriers were the most secure filtration speeds.

Chen Ling did not give up doing his own experiments.

There are some differences in the use of the same cultivation method on different people, otherwise why do some people practice faster and some people practice slower?

If he Chen Ling wants to improve his cultivation techniques, he will definitely find a way to improve them.

First of all, it is very certain that adding a filtering barrier can indeed speed up the speed of the aura entering the qi sea a lot, and the speed at which the aura influxes into the qi sea under the three barriers is close to the time when he didn't need to filter, but it has not yet reached the original level.

Chen Ling added another barrier, and the four barriers filtered the heaven and earth aura surging over at the same time, and after passing through layer by layer, the aura was clean and thorough, and it entered the sea of qi without hindrance.

Under the four barriers, the aura did not stop at all, and the speed was the same as the fastest speed he could reach before.

Then this problem is solved, and the four-layer aura filter is the best choice, which can allow the aura to filter out the polluting elements and enter the qi sea as quickly as possible.

Solving the problem also brings a new problem, that is, the problem of the consumption of ideas.

It is more difficult to solve this problem, and the best way is obviously to let yourself have stronger ideas, and Chen Ling will naturally do this in the long run, but there is a short-term solution in the short term.

Chen Ling focused his attention on the four spiritual energy filters.

The effect of the four-layer filter is the best, but where is the minimum of the best? This is what Chen Ling needs to spend time pondering.

The thickness, width, density, and distance of the four filters can all affect the filtration effect when the aura passes through, and the thinner the thickness, the smaller the width, the lower the density, and the closer the distance to ensure the best effect, the less the consumption of the mind will undoubtedly be.

Chen Ling began repeated experiments to ensure the best filtration effect while minimizing his mind consumption as much as possible. (To be continued......)
