Changkong Zhenren nodded when he heard this, this Li Pan and Guan Shengwei have a lot of prestige in the Longbridge Kingdom, especially in the army, and they have a bit of cultivation talent, and the Longbridge Kingdom under him has reported to him several times, hoping that he can include these two people in his door. It's just that later, the rebellion of the regeneration people broke out, the domestic situation in Longqiao was tense, and he himself was even more busy, and now when he heard Chen Gong say this, he knew some of the reasons, and immediately broke off the idea of accepting the two of them into the Evergreen Gate, this person who was favored by the envoy of the Yanlong Empire was not something he could accept casually.

"The envoy here, please, Longqiao City is the capital of Longbridge Country, and the people's dragon qi is gathered in one, but there is also great benefit to cultivating here. "Changkong real person said politely.

Chen Gong did not deliberately correct the title that Changkong Zhenren added to himself, since he wanted to make a play, that is, he wanted to make a ten, nodded casually, and together with Changkong Zhenren, he came to a verdant mountain peak next to the palace in Longqiao City, which is called Changqing Peak, which is the temporary residence of Changkong Zhenren when he came to Longqiao City.

As soon as Chen Gong entered the Evergreen Peak, he immediately felt that in addition to the rich aura here, as the real person of the sky said, there was a majestic and orthodox aura, bathed in it, the purity of the aura seemed to have improved a lot unconsciously, and it was the popular dragon aura here.

At this time, Chen Gong took a cursory look at the terrain where Changqing Peak was located, but it was closer to the center than where the palace was located, Chen Gong was proficient in the way of arranging formations, and he had the Nine Yuan Infant Phantom Evolution Heaven and Earth, and he was naturally clear about the doorway here, it seemed that there was no shortage of formation masters among the ancestors of Changqing Sect, although this popular dragon qi could not directly improve his cultivation, but mixed with the aura, it could accelerate the absorption, speed up the speed of cultivation, and the benefits were naturally many, but it was not so simple to draw out this trace of popular dragon qi from the royal orthodoxy。

After entering the quiet room, Changkong Zhenren and the Supreme Master retreated very consciously, after all, Chen Gong had a word first, he was injured at this time, and everything would be said after he finished recuperating, as for Xiao Jianxing and Stanley, naturally Li Pan arranged it.

After Chen Gong entered the meditation room, the surging demon source fire in his body had burned to the end at this time, and the reason why he still chose to meditate was entirely because the demon source fire in his body was very useful, and he hoped to be able to study one or two before using it in the future.

Now Chen Gong is consciously using the true yuan power to maintain the burning of the demon source fire, this kind of thing is tantamount to poison for others, but it is a good medicine for him, after all, the demon source fire is burning the true yuan power at the same time, it will also remove all the impurities and all the attributes contained in it, leaving only extremely pure energy, this kind of energy Chen Gong really can't think of what it will be, he only thinks that it is more pure and powerful than the true yuan power of the cultivator, I am afraid that only the power used by the immortals, so he simply called this kind of calcined energy the immortal yuan force。

One hundred copies of the true yuan power, after the demon source fire forging, can retain a point of immortal yuan power, such a large number of contrasts, for the vast majority of cultivators, are more than worth the loss, after all, the operation of the meridians in the body, the cultivation of the yuan infant in the purple mansion, and the usual spell casting, all have to use a large amount of true yuan power, if the true yuan power in a cultivator's body shrinks by ninety percent at once, even if the rest is the immortal yuan power, the effect is a hundred times that of the true yuan force, it is also an extremely distressing thing, I am afraid that even the most basic exercises can not be done。

Fortunately, Chen Gong's True Yuan is strong, and he can rely on the Xingchen Jue to absorb the enemy's True Yuan to replenish it, otherwise no matter how pure and powerful this Immortal Yuan Power is, he will not be blessed.

Trying to absorb the spiritual energy around the quiet room into the body, the demon source fire that was "warmed" by the true yuan power supplied by Chen Gong actually burned brightly, and the fire was several times more fierce than just now, Chen Gong couldn't help but have some doubts in addition to the pain, the same amount of true yuan, why the true yuan transformed from these spiritual qi that he had just absorbed burned much more violently than the true yuan originally stored in his body, which was similar to the effect of forcibly absorbing the true yuan of Qiu Ling Zhenren on the battlefield before.

Could it be that the burning intensity of this Demon Source Fire is still related to the "freshness" of the True Yuan Force? This obviously doesn't make sense, after all, the True Yuan Power in Qiu Ling's real body definitely can't match any "freshness".

But why is the burning intensity of the Demon Source Fire caused by the two different? Chen Gong fell into deep thought for a while.

In Chen Gong's opinion, the intensity of combustion is obviously related to the purity of the fuel, that is to say, the true yuan power originally stored in his body, which is used as the fuel for the demon source fire, is obviously lower than the true yuan power in Qiu Ling's real body, and even lower than the true yuan power that has just been absorbed into the body now.

But this doesn't make sense, the true yuan power in his body, after the dual cultivation of the Xingchen Jue and the Chaos Jue, is definitely purer than the true yuan power of ordinary monks in terms of quality, on the contrary, the true yuan power obtained by Qiu Ling Zhenren's containment and demonic energy and various negative emotions, as well as the aura that is now contaminated with dragon qi and the popularity of the people, is really impure. Speaking of which, among the true yuan power of the latter two, there are more impurities than one's own true yuan power.

At this time, a flash of lightning suddenly crossed Chen Gong's mind, impurities! This is the key!

What makes the Demon Source Fire burn is not the True Yuan Power in one's own body, but the various impurities contained in the True Yuan Power, most of which are spiritual things, including demonic energy, negative emotions, orthodox aura, and people's wishes......

Therefore, the true yuan power obtained in different ways is not the same as the burning intensity of the demon source fire, which completely depends on the number of spiritual impurities and its attribute characteristics, speaking of which, it is not an exaggeration to say that the demon source fire is called the fire of purification, but it is a pity that the people who can withstand this kind of domineering purification process may not be able to find a few in the entire source world.

And the immortal yuan force should be an extremely pure and thorough energy, not only does it not have these spiritual impurities, but there will be no so-called five element attributes, energy is energy, suitable for any place where energy can be used, and will not be affected by the so-called attributes.

Thinking of this, Chen Gong's mind couldn't help but become a little hot, the biggest purpose of his trip this time was to find and solve the problem of his own true yuan power being huge and complex, and he was haunted by demonic thoughts when he broke through. If the Demon Source Fire purifies the True Yuan Power in his body and converts all of them into Immortal Yuan Power, I am afraid that the problem of spiritual power full of demonic thoughts can be solved.

It's just that now Chen Gong's whole body, there is still a place that has not yet received the forgery of the Demon Source Fire, and that is his Purple Mansion. The Purple Mansion is the key position where the cultivator Yuanying is located, once there is any damage here, the cultivator will go mad and become a demon, and the cultivation will be completely wasted, and the heavy will set the fire to the body and die, so even if Chen Gong has made some previous inferences, he does not dare to easily remove the blockade of the demon source fire and let it enter the Purple Mansion.

As a good habit of a scientific researcher, it is essential to think boldly and verify carefully. Now Chen Gong has some general understanding of the strangeness of the Demon Source Fire, and the opportunity to come into contact with it in the future will definitely not be less, now temporarily use the Immortal Yuan Power to wrap the remaining Demon Source Fire and use it as a fire, so that he can boldly absorb the enemy's True Yuan Power in the future, and then use the Demon Source Fire to purify it and transform it into a more powerful Immortal Yuan Power. It's just that now the Purple Mansion must take strict precautions, and it can't let the demon source fire invade, in case there is anything wrong with his own ideas, and he will be ruined by cultivating his body, it will be miserable.

Now the research on the Demon Source Fire has come to an end, but for this newly acquired Immortal Yuan Force, Chen Gong has a little more thoughts to try, after all, there are two kinds of energy that can be mobilized in his body, one is the True Yuan Force, and the other is the Immortal Yuan Force, the former is huge, the latter is huge, how to distribute these two energies, whether these two energies can coexist perfectly is a question worth studying.

Carefully using the Immortal Yuan Force to divide the Demon Source Fire into several parts, in the spirit of safety, Chen Gong first completely wrapped one of the Demon Source Fire with the Immortal Yuan Force, trying to seal it in his body, but the Demon Source Fire was in the Immortal Yuan Force, and it only burned for a short while, and then it quickly weakened and extinguished, leaving no time for Chen Gong to react at all.

After another attempt, the result was still the same, and the other separated Demon Source Flames also had a weakened momentum, and it was only after Chen Gong had to input a little True Yuan Power that the Demon Source Fire regained its vigor.

Chen Gong shook his head a little helplessly, could it be that this Demon Source Fire still has to be like a pet, and it can't be kept in captivity? Usually, he regularly feeds it a little True Yuan Force, and when he absorbs the opponent's True Yuan, he releases it, purifies it vigorously, and then uses Immortal Yuan Force to raise it in captivity again, which is of course extremely troublesome, but the benefits of it are extremely great, Immortal Yuan Power is such a pure energy, how many cultivators can't dream of it, but he has made a lot of mistakes.

Although Chen Gong had not tried it yet to use the Immortal Yuan Force to cast spells, but in a short period of time, the strength of his meridians seemed to have increased a little under the nourishment of the Immortal Yuan Force, even if it was only a little bit that was difficult to detect, but as long as he remembered how strong his body was already transformed by the power of time and space, it was already very satisfying for Chen Gong to be able to improve so little.

After Chen Gong completed the captivity work of the Demon Source Fire Seed, he tried to introduce the Immortal Yuan Force into his Purple Mansion, but the Immortal Yuan Force was like oil poured into the water, and the True Yuan Force in the Purple Mansion went its own way, and there was no intention of entering the Yuan Infant to be absorbed by it, it seemed that it was because Chen Gong's Purple Mansion Yuan Infant was not pure enough to be integrated with it.

It seems that he still has to wait until the characteristics of the Demon Source Fire are thoroughly studied, and then fully purify his Purple Mansion Yuan Infant before he can truly transform the True Yuan Power in his body into Immortal Yuan Power.

After roughly dealing with the problem of Demon Source Fire and Immortal Yuan Force, Chen Gong ended this retreat and walked out of the ashram.

There were already disciples of the Evergreen Sect waiting outside the quiet room, and when they saw Chen Gong coming out, they received them carefully while asking people to inform the Changkong Zhenren and the Supreme Master.

In this Changqing Peak Hall, Chen Gong saw Changkong Zhenren, the actual ruler of the Changqiao Kingdom, and the Supreme Master of Shantai Temple, and there were many elders and protectors of Changqing Gate and Shantai Temple, and even Li Pan and Guan Shengwei were invited to attend, thinking that this was mostly because of Chen Gong.

Originally, the hall was full of gloomy clouds, but as soon as Chen Gong appeared, everyone looked like they had found the backbone of the main body, and the real person of the sky and the supreme mage came out of the hall to greet each other, and the rest of the people also stood up to greet each other.

Chen Gong saw the situation in the hall, how the atmosphere that was supposed to be relaxed and festive after the great victory became a little heavy, so he opened his mouth and asked, "Two fellow Daoists, during my retreat, did something major happen?"
