The Immortal Yuan Power in Chen Gong's body had been accumulated after passively receiving the Demon Source Fire several times, and since he didn't know the characteristics of the Demon Source Fire, he didn't dare to risk introducing it into the Purple Mansion. You must know that in Chen Gong's Purple Mansion, there is a huge Yuan Infant with a combination of nine infants, and behind it there are nine phantoms that are absolutely not available to other cultivators, constantly evolving the changes between heaven and earth.

This kind of purple mansion that is different from ordinary people, how could Chen Gong easily put the demon source fire that he didn't know about easily, once there was any accident, such as directly purifying his nine yuan babies into one, and losing this huge true yuan power to accommodate the source, even if he really had the true yuan power that could be circulated, with the intensity of the aura of the source realm, it would definitely not be able to meet the supply requirements of his immortal yuan power, and when the time came, the true yuan power that Chen Gong absorbed every day, because of the capacity problem, could only purify a little bit of immortal yuan power, then he would never want to make a breakthrough in the realm in his life。

In the past, Chen Gong could solve the battle by relying on the strength of his body, and there were very few times when he could use the power of the Immortal Yuan, even if he was slashing the evil ground, it was only a few times when the body method was accelerated, so Chen Gong did not plan to lure the demon source fire into the Purple Mansion in a short period of time to take risks.

However, now that he has encountered the strong opponent of the black dragon, Chen Gong has to rely more on the powerful power of the Immortal Yuan Force in the weak period of his physical body, so that he can barely gain the upper hand, and after a battle, Chen Gong is very unhappy to find that his Immortal Yuan Power seems to be about to dry up.

If there is no problem with the physical body, relying solely on the power of the true yuan and the strength of the physical body, Chen Gong is also confident that he can continue to fight with the black dragon in front of him who has the strength of the early stage of the catastrophe after the demonization, after all, this kind of strength that is forcibly improved after the demonization will definitely not last, and directly devouring the demon source fire to extract the huge energy in it, the burden on the body must be extremely heavy, and the black dragon will also have a period of continuous weakness at that time, and then Chen Gong can take the opportunity to kill it.

The biggest problem now is that before the negative effects of the black dragon demonization appear, the immortal yuan power in Chen Gong's own body can't stand it in the first place.

With Chen Gong's current situation, if he is alone, he can naturally use the remaining little immortal yuan power to turn around and retreat, even if the black dragon is fast, it is impossible to catch up with Chen Gong who is rushing with immortal yuan power, but unfortunately outside the battle circle, there is Qingmei who has not left the battle, for this woman, Chen Gong still has a very special feeling, after all, the two have saved each other's lives, it is not an exaggeration to say that it is a friend of life and death, not to mention some memories left by the time when the two fled together, so to let Chen Gong retreat alone and put Qingmei in a mortal state, he will never be able to do it。

At this time, Chen Gong didn't dare to make a sound to let Qingmei retreat, once Heilong felt that there was some relationship between the two, he was afraid that it would be Qingmei who would suffer first.

Chen Gong was at this time when the fighting spirit was in full swing, the more critical the moment, the more calm he became, if he wanted to save Qingmei and his own life, the only way to do this was to gamble.

Chen Gong's gaze suddenly became a little sluggish, and his originally cold eyes looked a little dull, but the movements in his hands did not pause at all, which seemed to be somewhat similar to the killing and coldness in the black dragon's eyes.

Indeed, Chen Gong had already handed over the battle in the outside world to a long-term battle instinct and keen spiritual sense to deal with at this time, and the sword momentum in his hand had changed even more, and he actually used the weak water sword technique that had not been used for a long time, which was still the sword technique used to fight the enemy at the beginning of Chen Gong's cultivation, known as the first defensive sword technique in the Kunlun faction.

It's just that this kind of extremely defensive swordsmanship completely sacrifices its aggressiveness, unless it is a grappling with people or a last resort, under normal circumstances, this kind of martial art that can be said to be beaten swordsmanship will not be used, which is also the reason why Chen Gong almost gave up practicing the weak water swordsmanship after using it for a period of time.

It's just that in recent years, with the improvement of Chen Gong's cultivation realm, especially after the nine infants in the Purple Mansion were united and the virtual shadow evolved into heaven and earth, many exercises that were not too valued before have been translated by Chen Gong, and there are always some special places that can give him a little inspiration. In particular, this weak water swordsmanship specializes in defense, completely abandons attack, and it may not be appropriate to fully use this kind of swordsmanship, but one and a half of the moves, the ultimate performance of self-protection, still benefits Chen Gong a lot, after the realization of this move, Chen Gong is now naturally very familiar with the weak water swordsmanship.

Although the weak water sword technique was used, the slightest advantage that Chen Gong had just achieved was completely lost, and it was even more difficult for him to parry in battle due to his dual purpose, but the weak water sword technique was suitable for the current close combat, which was almost a complete defense mode without him, and he only needed to use those defensive sword moves one by one, so compared to the earth-shaking things that would happen in his body, this disadvantage was nothing.

Obviously, she was glamorous about the change in the situation, and her hands couldn't help but clench tightly, although she didn't like Chen Gongfang's cold and arrogant appearance towards her, but no matter what, the two sides also had a common enemy. Now the two of them are completely hand-to-hand combat, and the change between body shapes is extremely fast, she can only barely keep up with this speed, if she is allowed to make a move, first, she has no confidence in melee combat, and secondly, she really doesn't know who the spell will be smashed on.

At this time, Qingmei has already given birth to the idea of retreating, after all, staying here can't help, looking at the current situation, I'm afraid that the white-robed monk is about to lose, once the black dragon frees up his hand, the first one who won't let go is himself. However, looking at the somewhat familiar white figure, Qingmei couldn't move her step, just hoping that the somewhat familiar white-robed monk could turn the situation around.

Compared to the true yuan power flowing in the meridians, the astonishing amount of reserves in Chen Gong's Purple Mansion is the real capital that can surpass ordinary monks of the same level, as soon as the Demon Source Fire rushed into the Purple Mansion, the giant Yuan Infant who was originally sitting in the center of the Purple Mansion with his eyes closed was driven by the instinctive crisis induction, and suddenly opened his eyes, and then the surging True Yuan Force slammed into the rising Demon Source Fire, and the fierce True Yuan Force impacted, and even almost suppressed the Demon Source Fire directly.

Even if a fire can easily ignite the gasoline and keep it burning until it is completely burned out, if the amount of gasoline is so horrible that it is poured on the flame, so that it does not even have room to come into contact with the air, then this situation can be reversed. The massive amount of true Yuan Force in Chen Gongzi's Mansion was not those stragglers in the meridians, with the direct command of Yuan Ying, this instinctive pounce almost disrupted Chen Gong's plan.

Chen Gong hurriedly collected his mind and slowly withdrew his true yuan power, and the demon source fire continued to pour in, and finally set off a sea of demon source fire in this purple mansion.

Chen Gong, who was in the fierce battle with the demonized black dragon, showed a little pain on his calm face, but the movements in his hands did not stop at all, and every sword was secretly in line with the heavenly truth, and he could always make the most perfect defense, even if the black dragon continued to strengthen his attack, he was never able to break through this layer of defense that seemed to be likely to collapse at any time, and slowly, the black dragon's red killing eyes began to have a trace of anxiety.

Introducing the Demon Source Fire, which can be called the natural enemy of the True Yuan Force, into the Purple Mansion of his True Yuan Force, even with the firmness of Chen Gong's will, there is inevitably a trace of wavering at this time, and the feeling is really no different from taking the initiative to insert a sharp knife into the heart, as long as there is a slight carelessness, or a misjudgment, it will be a death and everything will be empty.

With a huge amount of True Yuan Power as "fuel", the growth of the Demon Source Fire showed a trend of geometric multiples, and it soon changed from a small opening in the Purple Mansion to a sea of True Yuan Power that spread throughout the Purple Mansion. As the most important and fragile Purple Mansion for cultivators, now it is being ravaged wildly by the Demon Source Fire, and the small face of the combined Yuan Ying has changed from the previous calm to a painful distortion, and after a flicker, due to the large amount of burning of the True Yuan Force, the Yuan Ying can not even maintain the state of the combined body, and it is divided into nine, and the small faces twitch one by one, and the pain is endless.

Qingmei and the demonized black dragon, who were watching the battle from a distance, looked at Chen Gong with a painful face, and their moods could be described as worlds apart. Qingmei is constantly entangled between leaving and staying, with her cultivation in the middle stage of the merger, she can already be regarded as a super existence on the Evil Horse Continent, even if she looks at the entire Source Realm, she will definitely be able to rank among the first-class masters, her Dao heart is extremely firm, and it stands to reason that she will not affect her judgment at all for such a trivial matter. However, when she saw Chen Gong's face full of pain, a trace of inexplicable heartache rose in her heart, according to the current battle situation, she must have left, but there was a voice in her heart that kept telling her that if she left today, she might have a lifetime of regret and regret, and it would even affect her future cultivation, so that she would never be able to go further.

The demonized black dragon for Chen Gong's pain at this time, the anxiety in his eyes finally lightened, the demon source fire is the essence condensed by a master who is at least the strength of the Mahayana period, even if it is only with a little power in it, it is not something he can bear for a long time, if he can't defeat Chen Gong as soon as possible, the longer the time drags on, the more serious the sequelae will be, and the more damage he will do afterwards, even to the point that he can't bear it, so he found that Chen Gong only defended and did not attack, and his expression became more and more painful, the scimitar attack in the black dragon's hand became more and more violent, and the true yuan force fused with the rolling demonic energy, with his huge strength, every blow had the power of opening mountains and dividing the sea, It's just that Chen Gong, who is struggling to support, seems to be about to be unable to resist every time, but every time he narrowly survives the attack of the black dragon, looking at that situation, people always feel that the next time, he will be split into two pieces by the black dragon's scimitar.

Qingmei's heart was beating when he saw it, the black dragon attack was extremely depressed, he even wanted to roar, if he wanted to die, he would die happily, if he didn't die, don't make such an appearance to tease you Uncle Black Dragon!

Chen Gong didn't want to be happy, but now in his Purple Mansion, the Demon Source Fire was raging, and there was a tendency to burn the world, but in the face of Chen Gong's Nine Yuan Infants, he looked a little helpless. You must know that when these primordial babies were born, almost all of them were spawned by the fire power of the sun's true fire, and Wan Xingwei of the Blue Wind Legion used the yin and yang gossip mirror to concentrate on the sun's true fire to attack Chen Gong.

Although the massive amount of True Yuan Power in the Purple Mansion had been burned by the Demon Source Fire, leaving behind a large amount of Immortal Yuan Power, which was enough to support Chen Gong to cope with the battle in front of him, but if the Yuan Infant was not purified, Chen Gong would now face an embarrassing situation where neither True Yuan Power nor Immortal Yuan Power could be recycled.
