Eternal Immortal King

But because the people who deployed the formation were too meticulous at the beginning, not only did this formation have not failed, it still had the power it deserved. Tang Ao's spiritual power shook, and immediately rolled up a half-person-high boulder and smashed it towards the formation. Then Tang Ao saw that the boulder was not in the formation for an instant, and just as the boulder entered the formation, the boulder was instantly wrapped in a crimson flame and burned into nothingness.

"Ninth-Rank Spirit Fire!" Tang Ao's eyes jumped immediately when he saw the scarlet flame. Because Tang Ao's own Nether Fire is the existence of the Ninth-Rank Spirit Fire, Tang Ao still knows the Ninth-Rank Spirit Fire very well. Therefore, Tang Ao was sure that the flame that burned the boulder into nothingness just now was a ninth-grade spirit fire.

Tang Ao was secretly surprised. Tang Ao couldn't imagine that someone used such extravagance to leave a group of Ninth-Rank Spirit Fire here to arrange a formation. Although Tang Ao's Nether Fire is now a Ninth-Rank Spirit Fire, it is very difficult to advance Nether Fire into a Ninth-Rank Spirit Fire. Not to mention anything else, if Tang Ao were to leave Netherfire in a certain place to set up such a killing formation, Tang Ao would definitely not want to. But at this moment, it is clear that someone has done this.

If Tang Ao thought that there are good things in the depths of the Heiyan Volcano before it was only Tang Ao's guess, then now Tang Ao has determined that there must be some treasure here. Otherwise, who would spend such a high price, directly use a group of Ninth-Rank Spirit Fire to lay such a formation here, obviously trying to hide something.

It's just that Tang Ao has observed for a long time, and still didn't find anything special in the formation. After the formation, Tang Ao can only say that the person who arranged this formation really has two brushes. Because under the obstacle of this formation, even Tang Ao's celestial pupil could not see through what was behind the formation.

As for the observation with the soul mind, Tang Ao could only smile wryly, because Tang Ao discovered that as long as the soul mind penetrated into this formation, it would immediately be burned into nothingness. This shows how powerful this formation is. However, although this formation was powerful, Tang Ao wanted to crack this formation, but it was not impossible. It could even be said that Tang Ao had at least ten ways to break such a formation.

It's just that at the moment this group of Ninth-Rank Spirit Fire is connected to the entire formation. If the formation is broken by ordinary means, this group of Ninth-Rank Spirit Fire will immediately collapse after breaking the formation. Tang Ao still had ideas about this group of Ninth-Rank Spirit Fire. Even if Tang Ao couldn't use it, he could stay in the Seven Kill Sect, or use it for others.

There are countless strange flames in this world, but the truly powerful strange flames are something you can meet and never ask for. Tang Ao's Nether Fire grew to the 9th-Rank Spirit Fire, which cost Tang Ao a lot of effort, and there was a ready-made 9th-Rank Spirit Fire directly in front of him, and Tang Ao naturally couldn't let it go. After thinking for a long time, Tang Ao began to take out the refining furnace and began to refine the formation flag.

Tang Ao found it very interesting in his heart, because this break through the formation may have spanned an unknown number of tens of thousands of years. The two top formation mages on the Xuanhuang Continent had a battle across time and space. After careful observation, Tang Ao concluded that he could indeed break this formation, but if he wanted to take out the ninth-rank spirit fire in the formation completely, Tang Ao had only one chance.

As long as there is a slight difference, it is extremely likely to cause the spirit fire to run away or collapse. Once the spirit fire rages away, it will detonate the entire formation. This level of formation will explode. It is also a threat to a martial artist like Tang Ao at the eighth level of life and death. As for the collapse of the spirit fire, it is not what Tang Ao wants The result.
