Subduing a strong alien fire, this is a rather small opportunity for instrument repair. Eldest Sun Hao took the opportunity of subduing the Zixiao Burning Thunder Flame to complete the breakthrough of the heavenly moat between the Human Yuan Realm and the Earth Yuan Realm. And this time, Lin Feng subdued the Nine Heavens Purple Fire, which ranked tenth among the earth-level fires, and the benefits to Lin Feng were far greater than the situation of the original eldest grandson Hao.

The Earth Yuan Realm cultivator's perception of the main rules actually didn't start from scratch. For example, Lin Feng, in the stage of the Human Yuan Realm, he visualized the scene of chasing the moon several times, and in this process, Lin Feng's perception of the rules of yin will be improved.

When an ordinary monk thoroughly comprehends the rules of one of the five elements, he will almost be able to break through to the realm of the four heavens of the Earth Yuan Realm. However, the five rules of gold, wood, water, fire, and earth add up to form the rules of the five elements, and the rules of yin and yang add up to form the rules of the two instruments, but they are stronger than the rules of the five elements.

By the time Lin Feng had thoroughly comprehended the rules of Yin, Lin Feng would almost be able to break through to the Earth Yuan Realm Five Heavens Realm. When Lin Feng completes his comprehension of the rules of the sun, Lin Feng will be able to break through to the Earth Yuan Realm Seven Heavens Realm.

As long as he comprehended the half-formed rules of Yin, Lin Feng would almost be able to complete the cultivation of the Earth Yuan Realm's First Heaven Stage. In fact, before establishing a connection with the rules of yin, Lin Feng's several chances in the human yuan realm stage allowed Lin Feng to complete the comprehension of more than a tenth of the rules of the half-yin realm.

It's just that before Lin Feng and the rules of Yin were connected, Lin Feng's perception of the rules of Yin could not be expressed in the improvement of Lin Feng's combat effectiveness.

The rules of fire are also like this, and Lin Feng's perception of the rules of fire attributes is also not starting from scratch. In fact, according to Old Man Long, Lin Feng's current perception of the rules of fire may be deeper than his understanding of the rules of yin.

That's right, at the stage of Lin Feng's Human Yuan Realm, most of the chances were related to the rules of Yin. Only a few chances such as Lianhua Ice Hell and Fengluo Wutong are related to the rules of fire.

However, Lin Feng had subdued the strongest Strange Fire Ghost Ember Burning Fire of the Xuan Rank very early. The perception of the second main rule originally requires the treasure of the corresponding rule as a medium. Alien fire is one of the most precious forms of fire attribute rules.

In the years that Lin Feng had subdued the Ghost Light Ember Burning Fire and the Nether Ghost Fire, although Lin Feng had not taken the initiative to comprehend the fire attribute rules through these two different fires. But these two kinds of different fires that were not weak existed beside Lin Feng for a long time, and Lin Feng's perception of the rules of fire attributes slowly improved under such circumstances, without Lin Feng noticing.

In fact, every time he completed the subduing of a different fire that had not been subdued before, Lin Feng's perception of the fire attribute rules would be greatly improved. Under the instructions of Old Man Long, Lin Feng first established a connection with the rules of yin and the rules of fire. After Lin Feng became familiar with this connection, Old Man Long asked Lin Feng to completely expel the Ghost Ember Burning Fire from his body, which made Lin Feng begin to subdue the Nine Heavens Purple Fire.

The reason why there are so few high-level alien fires in the cultivation realm is not how difficult it is to subdue them, but that the alien fires themselves are indeed too scarce. The Nine Heavens Purple Fire of the tenth level of the earth level, if it is handed over to the monks of the Human Yuan Realm to subdue, it will of course be extremely difficult. However, Lin Feng had already reached the first heaven of the Earth Yuan Realm, and with a few simple formations, as well as some auxiliary pills that were not too high-end, Lin Feng still successfully completed the subjugation of the Nine Heavens Purple Fire.

The moment he completed the subduing of the Nine Heavens Purple Fire, Lin Feng suddenly felt that his connection with the rules of fire was a hundred times tighter. In just a moment, this feeling disappeared.

However, as soon as Lin Feng sensed it, he found that his perception of the rules of the fire attribute had improved greatly in the short moment before. Because of the realm barrier between the Earth Yuan Realm One Heaven and the Earth Yuan Realm Two Heavens, Lin Feng's perception of the rules of fire still did not reach the level of directly breaking through the Earth Yuan Realm Double Heaven after all. But as it stands. Give Lin Feng a period of time to stabilize the harvest of this time, it shouldn't take long for Lin Feng to break through to the Earth Yuan Realm Double Heaven Realm.

The cultivation of the First Heaven Stage of the Earth Yuan Realm was not easy, but it was really that the grade of the Nine Heavens Purple Fire was indeed too high compared to Lin Feng's current realm. If the earth-level different fire is also divided into nine levels, then the nine-sky purple fire, which ranks tenth among the earth-level different fires, can also be classified as the fifth grade of the ground level. A kind of super treasure of the fifth grade level of the earth level, the effect that can be achieved on a cultivator of the Earth Yuan Realm and a heavy heaven is of course amazing.

Normally, if those super geniuses cultivated step by step, it would take hundreds of years to complete the cultivation of the Earth Yuan Realm's First Heaven level.

If it weren't for Old Man Long's Nine Heavens Purple Fire, Lin Feng would have comprehended the rules of fire with the help of the two types of Xuan-level fires, the Ghost Ember Burning Fire and the Nether Ghost Fire. It would take more than a hundred years to break through to the Earth Yuan Realm Double Heaven.

This is also Lin Feng, the other Earth Yuan Realm First Heaven Cultivator whose main rule is the fire attribute rule, how can there be two different fires to help him comprehend the rules of fire?

What Lin Feng didn't know was that in fact, when Old Man Long was stripping off the mark that belonged to him in the Nine Heavens Purple Fire, Old Man Long had almost reached his limit. After guiding Lin Feng step by step to abandon the ghostly ember and burn the fire and replace it with the Nine Heavens Purple Fire, Old Man Long had reached the point where he ran out of oil and dried up. It's not that Lin Feng didn't pay attention to Old Man Long's face, it's just that Old Man Long didn't want Lin Feng to worry, so he didn't show any decline. However, this kind of behavior accelerated the loss of Old Man Long's soul. A few days passed, and Old Man Long suddenly lost his voice when he was talking to Lin Feng about some other knowledge.

After almost five hundred years of escaping from Zhongzhou with the Nine Heavens Purple Fire, Old Man Long finally sat down in the Sin Domain.

Lin Feng, as the only disciple of Old Man Long in the Sin Domain, participated in Old Man Long's funeral throughout the whole process. All kinds of trivial matters will be undertaken by the mountain gods, and in fact, Lin Feng doesn't have to be too busy.

When Old Man Long subdued the Mountain God Society, he first defeated several gang leaders of the Mountain God Society by force. Later, some good conditions were proposed, which made several gang leaders of the Mountain God Society decide to temporarily hang out under Old Man Long for a while.

The conditions that Old Man Long proposed at the beginning, he and his old man have met them all, and they have all been met exponentially. Liu Yi was able to break through to the Earth Yuan Realm Double Heaven Realm at such an early stage, and he couldn't do without the help of Old Man Long.

As for the other two sect masters of the Mountain God Society, their progress over the years has not been small. Even if it hasn't reached the point where it's about to break through, it's not too close.

In the years that Old Man Long has been in charge of the Mountain God Society, he rarely comes forward except when necessary. In fact, most of the decisions of the Mountain God Society are generally the same as before, and they are decided by the three of them. Old Man Long has brought them a lot of benefits, but he has not shared much power with them.

After a few years of hard work for Old Man Long to become the master of the Mountain God Society, several of them had already let down most of their vigilance against Old Man Long. And in the past few hundred years, Old Man Long has also helped them a lot on the way to cultivation. In their hearts, they actually regarded Old Man Long as a real big brother or senior brother.

Doing funerals and keeping filial piety, Lin Feng stayed in the crime domain for more than a month. After all the things that should be busy were done, Lin Feng and the others left the Sin Domain and flew in the direction of the Beast Emperor Domain.

Old Man Long's last one-hit kill against Hu Mingxu obviously frightened the Purple Flame Pavilion and his party. For a long time after that, those people from the Purple Flame Pavilion did not appear in the scope of the Sin Domain again. And in terms of the power of the Mountain God Society in the Sin Domain, even if Yu Hanfei was a super master of the Four Heavens of the Earth Yuan Realm, as long as he did not cultivate any strong earth-level stealth spells and could be in a stealth state for a long time, then it would be impossible for him to hide under the nose of the Mountain God Society without being discovered by the Mountain God Society.

The people of the Purple Flame Pavilion should have returned to the Burning Wasteland Domain, and Lin Feng and the others were not disturbed by others on their way to the Beast Emperor Domain.

Wu Ma's predecessors and several other high-level leaders in the Firmament Dragon Valley were of course very happy to see Lin Feng and his party. Of course, they weren't happy because of Lin Feng. But more than a hundred years later, they saw Xiao Hei's poor bloodline again.

When Lin Feng and the others were still burning the Wasteland Domain before, Wu Ma's predecessor actually wrote to Ji Sihan and a few of them, saying that if there was a chance, let Lin Feng return to the Beast Emperor Domain with Xiao Hei as soon as possible.

Lin Feng also knew at the time, but it wasn't until recently that Lin Feng found time.

And it was only now that Lin Feng knew why the Wuma seniors were in such a hurry to inform Lin Feng to take Xiao Hei back to the Beast Emperor Domain once.

The Firmament Valley found a poor spine.

For human monks, the Qiqi spine is also a relatively hard refining material. If you use the Qiqi backbone, you can make a fairly not weak attack magic weapon. It can be a collision type, and if the number of backbones is slightly larger, it can also be refined into a long whip magic weapon similar to the Nine Shadow Whip.

But for demon beasts, the backbone of a heaven-rank demon beast is an extraordinary treasure. Inside the spine, there is a high probability that there will be a remnant of the spinal cord of the demon beast. In the case of the Qiqi backbone, it is very likely that the Qiqi spine contains the blood marrow of the Qiqi. And even if it is not a top-level immortal beast-level Poor Qi Ancestral Beast, it is just an ordinary Heaven-level Qi Qi, and the Qi Qi blood marrow contained in its backbone is also an extremely precious supplement for demon beasts.

If the Qiqi bloodline has taken the Qiqi blood marrow, it has a fairly high probability of activating the bloodline.

This Qiqi backbone found in the Firmament Dragon Valley has been examined by several high-level officials in the Firmament Dragon Valley. Although this spine has not been completely broken, the possibility that it contains the Qi Qi blood marrow that can be taken is still quite large. Under such circumstances, the Firmament Dragon Valley urged Lin Feng and them to rush back as soon as possible.
