At Fang Zheng's age, he cultivated to the realm of False Dan, and they were all core disciples in the Flame Valley, and they were all cultivating in the inner peak of the Flame Valley, where the fire spirit qi was ten times richer than the fire spirit qi here, and that was the cultivation place that Fang Zheng longed for.

There was no strong fire spirit qi absorption in the stone room, and Fang Zheng was not idle, and began to practice the demon pills in the bodies of those demonized demon beasts. There are thousands of low-level demon beast demon pills here, and it will take a month to devour the speed of Fang Zheng's domineering Dao Sect exercises. After a month of cultivation, a lot of fire spirit qi will be condensed in this stone room.

As Fang Zheng began to devour and absorb those demonized demon pills, what made Fang Zheng feel the difference was that as the pure demonic qi transformed by the demonized demon pill entered his body, a wisp of black flame in the dantian was rapidly growing.

"What's going on, how can the power of the fire spirit in the body change with the absorption of the energy of the demonizing demon pill? If you look at it at this speed, it won't be long before the power of the fire spirit in the body will turn into this black flame, so can you still retain your identity as a fire cultivator?" After absorbing hundreds of second-order demonized demon beast demon pills in a row, Fang Zheng found that the black flames in the dantian had grown a little stronger, and when Fang Zheng saw this, he couldn't help but stop his cultivation and began to frown.

In fact, what Fang Zheng didn't know was that the black flame of his dantian was not an ordinary flame, but the demonic qi in his body was pure to the extreme, and because he had cultivated the flame making technique, this was the condensed demonic flame. The power of this demon flame is several times higher than the power of the fire spirit in his body, which is comparable to the Dan fire in the body of a strong person in the Jindan stage, and even the Dan fire in the body of a strong person in the Jindan stage is not necessarily as powerful as the demon flame in Fangzheng's body. If all the Dan Flames in Fang Zheng's body were transformed into Demon Flames, it would be another Yizong killing weapon in Fang Zheng's hands.

"The abnormal changes in the power of the fire spirit in this dantian must be related to the domineering Dao Sect exercises. I am a demon cultivator, and I can't change this matter no matter what. Since it is fate, then what is there to worry about! This secret will be discovered sooner or later, and what can be done now is to conceal it day by day. For the abnormal changes in the power of the fire spirit in his body, Fang Zheng was also powerless, and could only sigh secretly. Maybe when his identity as soon as his demonic cultivation is revealed, then it will be time for him to leave the Valley of Flames!

As soon as he let go of his scruples, Fang Zheng had nothing to worry about! Those who devoured and absorbed the demonizing demon pill had no scruples, and the domineering Dao Sect exercises in his body were running at full strength.

Day after day, Fang Zheng entered the practice stone room and never appeared. The whole day was spent refining the Demon Beast Inner Dan. This demonized demon pill can only be absorbed by Fang Zheng unscrupulously. Thousands of demonized demon pills turned into ashes in Fang Zheng's hands. Fang Zheng devoured the pure demonic energy he had absorbed to reach a terrifying point. The wisp of black demonic flame in the dantian has grown several times stronger, it used to be just a strand of hair, but now it has become as thick as a toothpick.

During this period, Fang Zheng had entered the magic jar space once, and the demonic qi in the magic jar space was even more dense to the extreme, and there were even signs of liquidity! There was always a thick layer of black mist in the sky above his head. The black fog was so thick that it seemed to be dripping water. If you cultivate in such an environment, Founder will get twice the result with half the effort.

After a month of accumulation, the practice stone room where Fang Zheng was located had accumulated enough rich fire spirit qi. When Fang Zheng absorbed all the fire spirit qi in the stone chamber. What surprised Fang Zheng was that the black ** flame that was originally only as thick as a toothpick has grown several times stronger, and has become as thick as chopsticks! Feeling that the demon flame in the dantian has grown again, Fang Zheng suddenly had a trace of enlightenment, the magic flame in the dantian is related to the power of the absorbed fire spirit, if there is enough fire spirit power, Fang Zheng can completely transform the fire in the dantian into a black demon flame in a short period of time.

"Hurry!" Fang Zheng suddenly shouted, and a fiery red flame suddenly appeared in Fang Zheng's hand. The flames that suddenly appeared were not mixed with black demonic flames, but only pure fire spirit power.

Fang Zheng turned his hand and extinguished the fist-sized flame in his hand, and with a move of his hand, a ball of shocking temperature was exuded, and a red and black mutated flame suddenly appeared in Fang Zheng's hand. The temperature emitted by this black-red flame reached a terrifying height, and a scorching wave of fire rushed towards it, and its smell was several times that of the red flame just now.

"I see, if that's the case, then the black demon flame can keep him mutating. I don't have to worry about being discovered! I'm still a pure fire monk. Fang Zheng summoned two different flames with two different methods, and suddenly couldn't help but laugh heartily.

There has always been such a thought in Fang Zheng's heart, if he wants to summon the black mutant demon flame, he can only input the pure magic power, and to summon that ordinary flame, he only needs to directly urge the power of the fire spirit in his body! Far from this, this is just a guess by Fang Zheng, but he didn't expect Fang Zheng's attempt to succeed! This also made Fang Zheng greatly accelerate the determination of the demon flame in his body to continue to mutate.

If you want to speed up the speed of the demon flame in your body, you can only use a large amount of fire spirit power! But now the power of the fire spirit in the practice stone room where Fang Zheng is located can't satisfy Fang Zheng! You have to change places.

Fang Zheng bounced off the dust on his body, withdrew and walked outside the stone room, if he wanted to get a good practice stone room, especially an outer disciple like Fang Zheng, he had to challenge the core disciples inside the door! As long as he defeated the other party, he would be able to obtain the other party's practice stone room.

In the Valley of Flames, in order to motivate the cultivation of the disciples, the sect allows the disciples to challenge privately, as long as you have enough strength, even if you are an outer disciple, you can challenge the inner disciples. It is possible for the inner disciples who challenge the cultivation of the Jingdan stage.

With Fang Zheng's current cultivation in the Fake Dan Realm, there is still a certain chance of success if he wants to challenge the core disciples of the inner gate, and it is a little difficult to challenge the core disciples of the inner gate who have a cultivation cave! However, the practice stone rooms of some of the core disciples of the inner gate also have some cultivation caves that are comparable to those of the powerhouses of the Jindan period, and this is the purpose of Fang Zheng's trip. As long as you cultivate to the realm of Jindan, you can open up a cave of your own on the peak in the inner gate.

Out of the practice stone room, Fang Zheng went to the utility hall. In the Sundry Hall of the Valley of Flames, Fang Zheng spent ten lower-grade spirit stones to copy a jade slip. In this jade slip, the distribution map of all the practice stone rooms in the Flame Valley is marked, and in this distribution map, you can see which stone rooms have a strong fire spirit qi, and it is also marked with some simple information about the owner of the practice stone room. There are such jade slips in the Valley of Flames purely to encourage the disciples to work hard to cultivate. After all, this is a world of the jungle, fit for survival. In this jade slip, you can see a simple information about the opponent you are about to challenge, which will help you in the next challenge.

The No. 9084 practice stone room where Fang Zheng is located is also in the middle and upper class in Dizi Peak, which is very suitable for the cultivation of monks in the foundation building period. However, Fang Zheng now thought that it was a false pill realm, so he naturally felt that he was inadequate! However, the assessment task of this inner disciple was delayed, and if Fang Zheng wanted to obtain a good cultivation environment, he could only challenge the inner disciple in the Valley of Flames!

"The practice stone room from No. 1 to No. 100 is where the inner disciples of the pride of the heavens in the Valley of Flames live. His cultivation has reached the realm of False Dan. The practice stone room from this number to the hundredth is the best practice stone room in the Dizi Peak. Then the goal of my trip today is to choose from this!" Fang Zheng's divine thoughts invaded the jade slip in his hand, and after understanding the information in the jade slip's contents, Fang Zheng couldn't help but flash a look of determination. If you want to challenge, then you have to challenge the most powerful and get the best cultivation resources.

Dizifeng is the place where the disciples below the Jindan stage cultivate, if the cultivation reaches the Jindan realm and has made outstanding contributions to the sect, they can enter the Tianzi Peak to cultivate. If you can't enter the Tianzi Peak to cultivate, these Jindan Stage disciples can also open their own caves in the Dizi Peak. And although the practice stone room from No. 1 to No. 100 that Fang Zheng chose was not as good as the cultivation cave of the Jindan Period Sect people, it was also the best practice stone room in the entire Dizi Peak!

There are hundreds of thousands of inner disciples in the Valley of Flames, and the disciples who can or can get the top 100 practice stone rooms are all proud figures like the sons of heaven in this Valley of Flames, and among the hundreds of thousands of inner disciples, they can be said to be the top 100 under the cultivation of the Jindan period, and only in this way can they occupy such a good practice stone room.

In the later stage of foundation building, Fang Zheng was able to challenge Yang Lin in the realm of the false pill and be invincible. And now Fang Zheng is in the realm of the False Dan, and the monks who challenge the False Dan Realm among the disciples of the Inner Gate of the Valley of Flames, Fang Zheng has a seventy or eighty percent certainty. What makes Fang Zheng feel embarrassed now is that among the 100 people, Fang Zheng doesn't know who to pick.

"Hey, isn't this Nie Yan? Senior Brother Nie, where are you going?" Just when Fang Zheng was embarrassed to choose the opponent to challenge, Fang Zheng suddenly saw an acquaintance in the outer hall of the Valley of Flames, this Nie Yan had a lot of contradictions when he entered, and the two finally broke out into a big battle, and when he saw the acquaintance, he couldn't help but greet him.

"Fang Zheng, you are Senior Brother Fang Zheng, oh no, it's Senior Brother Sun, what a coincidence we have! As soon as he saw Fang Zheng, Nie Yan couldn't help but look puzzled, and then asked Fang Zheng.

Although this Nie Yan has a contradiction with Fang Zheng, he was defeated by Fang Zheng and upright, and the other party is so righteous that he has no jealousy. He is not a member of a big family, and he does not have a strong background, so he naturally does not want to offend Fangzheng. At this time, seeing that Fang Zheng took the initiative to greet him, he was also happy to turn his rivalry with the other party.
