Chapter 505: Toxic Purple Mist

So after Tang Ao's spirit power marked an ice worm, Tang Ao immediately opened a passage to the ice cave, and then leaned towards the ice cave. The ice cave is not very far from Tang Ao's location, so after walking for a while, Tang Ao came to the location of the ice cave. But Tang Ao did not rush into the ice cave, because Tang Ao had already seen a lot of ice worm corpses around the ice cave. Although the ice worm was small, the ice worm's corpse was rigid under this ice layer.
In addition to ice worms, there are some strange monster skeletons. These monsters have a common feature, that is, they are relatively petite. Although Tang Ao had never seen these monsters, he could detect one or two from the skeletons they left behind. In addition, the bones of these monster beasts appeared black and purple, and they were obviously poisoned and died.
In this way, the purple mist that reunited in the snow cave must be a very powerful strange poison. In addition to the strange poison in the snow cave that reunite and not disperse, there was also a formation on the ground of the snow cave that Tang Ao had never seen before. However, Tang Ao judged from the formation of the formation that this dead warrior was not the warrior who tried ten thousand years ago, but the one who entered the Underworld Trial with Tang Ao and others not long ago.
It's just that there were too many people who entered the Underworld Emperor's secret realm trial, so Tang Ao had no impression of this person. Tang Ao's heart moved, and the light green dots of the jade bone vitality soul in his body kept beating in Tang Ao's palm. The reunion of the purple mist Tang Ao felt a little bit powerful, so without knowing the bottom of the purple mist, Tang Ao decided to test it out with his jade bone vitality and soul.
Tang Ao condensed the jade bone vitality soul into a light green transparent butterfly, and then broke a hole in the ice cave, allowing the jade bone vitality soul to fly in. After Tang Ao broke through a gap in the defensive formation, the purple mist that was reunited and not dispersed was about to surge towards Tang Ao, but Tang Ao instantly sealed the gap with a mysterious air.
After Tang Ao sealed the broken gap, the jade bone vitality soul in the snow cave became the target of this purple mist. Zi Wu instantly flew towards the butterfly transformed into the Jade Bone Vitality Soul, and the Jade Bone Vitality Soul also flew past without showing weakness. The moment the two collided, Tang Ao's soul was burning.
The life soul of the warrior is closely connected with the warrior, and the life soul is damaged, and the warrior will also be injured. Under the collision of the jade bone vitality soul and this purple mist, the jade bone vitality soul is scattered by the purple mist. The Jade Bone Vitality Soul soon returned to its original state, but Tang Ao still clearly felt that the Jade Bone Vitality Soul was hit by this evil purple mist.
Seeing this, Tang Ao couldn't help but put away the jade bone vitality soul, then Tang Ao looked at this snow cave with some embarrassment. After Tang Ao walked around the snow cave carefully, he found that the formation this man had laid was not very clever. Although Tang Ao wasn't considered a first-rate formation master, the formation Tang Aobu produced was much stronger than this formation.
Moreover, Tang Ao also saw that this formation did not have a nested formation for gathering spiritual power, that is to say, this formation was maintained by the spiritual power of the spiritual stone. Once the spiritual power of the spiritual stone was exhausted, the formation The law will disappear, and the purple mist in the formation will also escape to the outside. Tang Ao had already experienced the power of this purple mist, and once the purple mist escaped outside, it would definitely be harmful.
Therefore, Tang Ao was considering whether to reinforce this formation, increase the service life of this formation, or completely eliminate the purple mist. At the same time, Tang Ao secretly thought in his heart that the middle-aged warrior sitting inside was not fatal, or even scarred, but the vitality of this person was gone.
At the same time, this person couldn't help but die, and everything in the snow cave after his death was also very strange. If it is said that this person is about to set up this formation in this snow cave and leave this purple mist, then this person should not be so calm. Just now, Tang Ao carefully observed the formation of this person. Although the quality of this formation was a bit inferior, the formation of this formation was extremely serious and rigorous. It is absolutely impossible that such a formation was laid out in a hurry before his death. .
