After all, the Ming emperor was invincible in the xuanhuang world by virtue of a ghost soul. With the improvement of Tang Ao's cultivation, the power of the soul of the underworld was gradually released from Tang Ao's hands. With Tang Ao's consciousness left, the Yin soldier again recovered to a state of bewilderment. I saw him stand up in a daze, and then continue to hunt around the soul.

Many of these weapons are the same as those of the ancient soldiers. But this time Tang Ao did not study one by one. The purpose of Tang Ao's escape into the underworld with his soul is to find the nether fire.

After closing his eyes and feeling for a moment, Tang Ao immediately noticed the location of the dark fire. In other places, even in the thirty-six realms of Zhenwu, only the demon and ghost world owns the nether world fire. Even if the other martial arts circles have the ghost fire, the number is very small. However, Tang Ao has the soul of the underworld and can freely enter and leave the underworld.

In the underworld, although the ghost fire is not as common as the soul, but the number is also a lot of terror. After walking for a distance, Tang Ao hands a move, immediately from the distant void to a flame. Just keep this flame flying over, Tang Ao put his hand on it, the dark fire stayed in place, and soon disappeared into the nether world.

The reason why you didn't collect the ghost fire was that it only reached the level of six spirit fire. What Tang Ao is looking for now is the nether fire of grade 9. If you want to use netherworld fire to evolve into immortality, ordinary people only know what they need. However, with Tang Ao's increasing understanding of the nether world fire, Tang Ao knows that the Youming fire is advanced to immortal flame, which requires a lot.

First of all, you must cultivate the spirit of fire. But there is a very important premise, that is, under the fusion of the life and soul of the underworld, the Youming fire of Jiupin Xianyan will become immortal.

There is only one soul in the world, and it has been awakened by Tang Ao. That is to say, if Tang Ao doesn't fall, others will never get immortality.

"Here When Tang Ao is looking around, Tang Ao suddenly sees a light. In Tang Ao not far away, there are three groups of flames floating quietly. After seeing the three flames, Tang Ao was full of joy. Because these three groups of flames are all the nether fire of Jiupin spirit fire level. Without any hesitation, Tang Ao made a resolution, and the three flames floated behind Tang Ao, closely following Tang Ao.

After harvesting three groups of fire, Tang Ao is in a good mood and continues to search in the underworld. The underworld is too vast, even if Tang Ao's current cultivation, can only turn around in the outside of the underworld. If you want to go deep into the underworld, you need Tang Ao's real body to come, or Tang Ao's cultivation is more powerful. After arriving at the huntian realm, he can travel freely in the underworld like the emperor of the underworld.

Along the way, Tang Ao saw a lot of dark fire, but Tang Ao was very helpless. However, Tang Ao didn't meet any of them. Maybe this is the outer world of the underworld. It's a great luck to be able to capture three clusters of the nether fire of Jiupin spirit fire level at a time. As a result, Tang Ao walked most of the circle and did not find the ghost fire that met his requirements.
