When Fang Kun was trying all kinds of supernatural powers, he was also paying attention to the situation in the inner circle outside, but whenever there was a demon beast that was tortured by the earth core molten flame and only had one breath left, Fang Kun decisively put it into the inheritance ring.

In doing so, he also wanted to stay here for a while longer, after all, with the help of the Earth Core Molten Flame, he had already destroyed more than eighty demon beasts, and if he didn't take this kind of measure, it was estimated that he would soon be transferred to the Fifth Heaven!

Not only did he want to take this opportunity to hone himself, but more importantly, the terrifying energy in the bodies of these demon beasts really made him salivate!

You must know that even those demon beasts that are eroded by the melting flame of the earth core and only have one breath left, they are equivalent to a low-grade spirit vein, although Fang Kun doesn't know if those demon beasts can continue to be suppressed after the four heavens, he still wants to try it, if he succeeds, not only will his spiritual root undergo earth-shaking changes, but it will also save him a lot of resources!

Otherwise, if he wants to get so many spiritual veins on his own, he doesn't know that it will be the Year of the Monkey!

The most important thing is that not only does he need enough energy to advance, but the Earth Core Molten Flame also needs terrifying energy if he wants to advance, so he will definitely not give up this rare opportunity!

Time passed slowly, Fang Kun activated the formation again and again, and he himself was constantly honing, a kind of magical power, gradually mastered by him, the time of release, the heat of the hand, getting better and better, of course, under his continuous attempts, the power of all kinds of magical powers, also getting stronger and stronger, although it was still unable to break through the defense of the demon beasts, but it could already affect the attacks of those demon beasts, and even, it could already faintly shake the huge body of the demon beasts!

The next day, Fang Kun's inheritance ring had already received nearly three hundred demon beasts, and the Earth Core Molten Flame had finally advanced again!

On the fourth day, after Fang Kun was familiar with all kinds of supernatural powers, he was already thinking about how to improve it to make it more suitable for his own fighting style, and at this time, nearly a thousand demon beasts had been collected in his ring, and the earth core melt flame had also undergone its fourth transformation, and its power had increased greatly, and the speed of devouring demon beasts had greatly increased, and the terrifying demon beasts, under the ravages of the earth core melt flame, would fall in less than a minute.

Fang Kun could only reluctantly stop the battle, and instead began to pay full attention, because, if he was not careful, the demon beast trapped in the magic circle would die!

What's more, the space in the inheritance ring is no longer enough, and the demon beasts that were originally placed separately can only be stacked up, because he is worried that these demon beasts will devour each other and thus restore their strength, he can only place a ban in each demon beast's body!

After all, in this ring space, under Fang Kun's manipulation, except for the area where the spirit vein was located, the other areas had been completely separated by Fang Kun, without the slightest aura, those demon beasts wanted to recover, they could only devour each other, he naturally didn't want this to happen, so he could only trouble himself.

Although he still has the golden beads, he doesn't want to bring these terrifying demon beasts into the golden beads, after all, there are four Tang Ruxin living inside, if he is not forced to do so, he will not bring any possible danger into the golden beads!

On the eighth day, nearly three thousand demon beasts had been stored in the inheritance ring, which almost filled most of the space, and the Earth Core Molten Flame had finally advanced again!

Obviously, as the original level of the Earth Core Molten Flame increased, the energy required for promotion became more terrifying, so although his power became stronger and the speed of devouring became faster, it still took four days and devoured nearly two thousand demon beasts before he completed the fifth transformation!

Feeling that there were still a lot of monks fighting in the Four Heavens, Fang Kun had no intention of leaving, but continued to hunt, while looking forward to the sixth promotion of the Earth Core Molten Flame!

However, at the same time, some monks gradually paid attention to Fang Kun's situation here!

Finally, on the tenth day, someone rushed here, contacted Fang Kun through the magic circle, and wanted to form an alliance with Fang Kun, after all, this kind of array magic weapon is not available to all monks, at this time, most of the monks who continue to stay here are from ordinary backgrounds, although they will also use the magic circle in the process of fighting, but it is all temporarily arranged, and there is no existence of the formation master, even if they arrange a sixth-level magic circle, they will be quickly broken by the demon beast, far less stable and worry-free!

Therefore, it was normal for other monks to want to join forces with Fang Kun!

However, it was obviously impossible for Fang Kun to agree, although those people could feel the extraordinaryness of the magic circle, however, they couldn't detect the situation inside the magic circle, so Fang Kun was not worried that he would be exposed!

However, when some monks nearby saw Fang Kun keep releasing batches of demon beasts into the magic circle, but did not see him leave, they were still curious, but Fang Kun was very cautious, every time the magic circle was withdrawn and opened, it happened in an instant, and there were space magic weapons to hide themselves, and those monks could not enter it at all under the entanglement of countless demon beasts, so they could only give up.

But gradually, Fang Kun's reputation still spread, and almost everyone knew that among the Four Heavens, there was a monk who was constantly honing himself using the magic circle!

In the eyes of those cultivators, Fang Kun must be a genius disciple of a certain great sect, otherwise it would be impossible for him to still have such a heavy treasure as a seventh-level array plate, and since he was a disciple of a great sect, he had broken away from the team, and he insisted on being here with the array plate, he must have wanted to hone his body!

A few days later, the surrounding monks gradually disappeared, and some of them had already completed the slaughter of a hundred demon beasts and were transferred to the Fifth Heaven, and of course, some of them fell here.

From this, it can be seen how powerful the demon beasts in these four heavens are, not only Fang Kun is helpless, but it is even more difficult for other monks to slaughter, after all, not every monk has such a heavy treasure as alien fire, and more people can only form a team, relying on the strong strength of the team, with the help of the magic circle, besieging one demon beast after another to death!

What happened in the outside world, Fang Kun naturally didn't pay attention, at this time, he had already put all his thoughts on the collection of demon beasts, after the five promotions of the earth core molten flame, he was already infinitely close to the peak of the earth fire, the power was already incomparable, Fang Kun was almost slightly distracted, there would be demon beasts dying in the sea of fire, Fang Kun could only keep an eye on it at all times.

On the thirteenth day, nearly 10,000 demon beasts had been collected in the inheritance ring, occupying almost all the space, and moreover, it was still under the accumulation, otherwise it would be impossible to put down so many demon beasts!

However, Fang Kun still had no intention of stopping, because, although the Earth Core Molten Flame was devouring terrifying energy all the time, it still hadn't completed the sixth transformation!

Obviously, in order to make the Earth Core Molten Flame complete the sixth promotion, the energy required was so terrifying that Fang Kun couldn't even imagine it!

Of course, the most important thing is that among the nearly ten thousand demon beasts he collected in the ring, there were only less than four hundred demon beasts with heaven-level spiritual roots!

Obviously, although the number of demon beasts here is large, the proportion of demon beasts with Heavenly Spirit Roots is also limited, and it is impossible for him to do the first time before, out of the hundred demon beasts that are included in the magic circle at one time, twenty of them are all Heaven-level Spirit Roots!

And according to his previous experience, the spiritual roots below the heavenly level no longer have any meaning to him, and the heaven-level spiritual roots in the bodies of these demon beasts are equivalent to three times that of ordinary monks, so calculated, these more than 400 heavenly spiritual root demon beasts are equivalent to 1,200 monks with heaven-level spiritual roots, although this number is already very terrifying, but Fang Kun is still not too sure that he will break through his spiritual roots to the level of the best spiritual roots in one fell swoop!

Of course, this was not because Fang Kun was too greedy, it was also because he had to do it, after all, he needed to implant spiritual roots for Tang Ruxin and the four of them, according to his experience in his previous life, the better his own spiritual roots, the greater the possibility of successful implantation, of course, this was without considering the Heavenly Tribulation!

Since there are such demon beasts here, almost endless, he naturally doesn't want to miss it, otherwise out of this secret realm, if he wants to find enough Heavenly Spirit Root Cultivators to devour, it is definitely not something that can be done in a short time, besides, he may not be able to do it, after all, so far, the monks who have been devoured by him are basically his own enemies, and those who have no grievances with him, he really can't do it!

For example, the stunning woman with the Heavenly Spirit Root in the Inheritance Ring before, he never thought of devouring the other party's Spirit Root!

However, just when Fang Kun was immersed in frantically collecting demon beasts, on this day, a team gradually approached here, and the person who took the lead was none other than the Wudao of the Wuzhen Sect.

A group of thirteen people, all of them were distraction period monks, including the tall monk who had banned Fang Kun before, that is, the distraction period master who protected the young master of Nan Chen, according to the strength of these people, they could have entered the Fifth Heaven a long time ago, but in order to find Fang Kun and regain the inheritance ring, these people have been staying in the Fifth Heaven and have no intention of leaving at all, obviously, these people can't find the inheritance ring, and they will definitely not stop!
