Xizhou of Qi State, Magic Dragon Mountain.

Pan Yan and Du An, the two of them, were suspended above a mountain col, not so much a mountain col, but a sinkhole in the middle of the mountain, where the residual forbidden power was permeated, and on the flat ground, a layer of dark yellow aura was emanated.

Not long ago, with the help of the Star Moon Pavilion Formation Master, they had cracked most of the prohibitions in the True Demon Pool Cave, and in various parts of the Demon Dragon Mountain Range, a chain reaction suddenly appeared, and many mountains collapsed, revealing many hidden prohibitions.

Pan Yan's divine sense sensed carefully, and slowly fell, and when his feet stepped on the ground, he suddenly felt his body sink, and the gravity increased several times.

This bit of power blessing is nothing for the bone transformation period body cultivation, but he said with a happy expression: "The gravity has increased, this should be one of the sources of Xuanhuang Qi, Duan, let's go down together." ”

Du An hesitated and said: "Senior Brother Pan, the stronger the Xuanhuang Qi, the greater the gravity, according to the judgment of the disciples of the Star Moon Pavilion, the gravity in the depths of the Demon Dragon Mountain is probably more than a thousand times, with my physical body ......"

Pan Yan stretched out his hand and gestured: "Your small body, as long as you lie on my back, it is within the range of the source force field, and the thousand-fold gravity is only a hundred thousand catties of power, and the source force field can easily resist it." ”

"Besides, without your Yuan Infant power, I wouldn't be able to destroy the high-level Earth Escape Talisman. ”

"The rock here is impregnated by the Xuanhuang Qi, and the toughness is no less than that of the Broken Dragon Stone, only the Earth Escape Technique can be passed, if the master is here, he can penetrate it, but I have this strength, I'm afraid I can't dig a hundred zhang. ”

Du An looked at Pan Yan's body, the distorted force field with a range of about two feet, hesitated, but still nodded, he knew that after the body cultivation entered the bone transformation stage, he could only cast some foundation building stage level spells, let alone advanced ones.

So, he flew to Pan Yan's thick back, the two-foot source force field just wrapped his body, and then a high-level spirit rune appeared in his hand, the power of the Yuan Infant surged, and the rich earth attribute aura wrapped the two of them, and the yellow mangs flashed slightly, disappearing in place.

Xuanhuang Qi is extremely rare in the world of cultivating immortals, and it requires special earth veins to be conceived, and for those who cultivate earth attribute exercises, Xuanhuang Qi is an extremely precious treasure.

However, they will only collect some on the periphery, it is difficult to go deep into it, the thicker this special aura, the stronger the attached gravity, and only a few legendary earth path supernatural powers can resist this gravity.

Pan Yan and Du An went down, not to collect Xuanhuang Qi, but to find the source of the strange toxins in the True Demon Pool Circle.

After this period of research, Duane found that this toxin was extremely valuable, if it was refined into his hundred poisonous powers, it could even increase the cultivation of poison skills, and it had a harmonizing and dissolving quality for other poisons.

The several holy poisons of the Poison Refining Pavilion, with the blessing of this toxin, are likely to refine a stronger toxin, but the refining method requires a lot of material tests.

Although the Holy Poison is powerful, its lethality is at the level of the early Yuan Infant stage, and it is already quite difficult to face the strong mana of the middle Yuan Infant stage, let alone a strong person at the level of a great cultivator.

Not long ago, several holy poisons were able to kill the primordial infancy of the three major demon dao families, and the main reason was that they cooperated with the Great Five Elements Force Field, which produced terrifying lethality.

If you can obtain a large amount of this special toxin, or know its source, it will not only greatly improve Duane's method of refining poison. In case a terrifying poison that can threaten the Great Cultivator is refined, and with the prohibition of the Great Five Elements Force Field, I am afraid that the strong people in the late Yuan Infant period will fall into it, and it will be more than lucky.

......

Layers of dark yellow rocks flashed around the two of them, and the Xuanhuang Qi belonged to an extreme earth attribute aura, and Pan Yan's physique was very sensitive to it, constantly adjusting the direction.

As the two of them deepened, the gravity attached to their bodies became stronger and stronger, and with the support of the same nature of the source force field, Duane did not feel the slightest discomfort.

"Hey, the color of the nearby rocks has changed a little, is the breath on it that kind of toxin?" Pan Yan couldn't help but ask as he watched the nearby rocks turn gray.

Duane's eyes flashed with excitement: "That's right, the rocks here are actually soaked in toxins, and it can be seen that the source of the toxins is the source of Xuanhuang Qi." ”

Pan Yan was just about to say something, but suddenly his expression was happy: "There seems to be a cave in front." ”

After speeding away for a moment, the eyes of the two lit up, and they fell into a grotto dozens of feet, and a heavier pressure surged.

The gravity here is almost twice as much as the outside, and it is more than a thousand times that of its own gravity, and ordinary bone treasure Dacheng cultivation can't support it here for too long.

"Hey, what kind of material is this large magic circle, it can actually resist the gravity field of Xuanhuang Qi. ”

"The toxins are so strong, and so on, they emanate from this circle. ”

The most striking thing in the grotto is a triangular circle, which looks very different from the normal circle.

The rune lines on it are strange, not like the means of immortal cultivators, and the materials that make up the magic circle are also unusual, the stone gray surface is arranged with subtle edges and corners, which looks like the scales of some kind of creature, and the aura revealed, Pan Yan has a sense of déjà vu.

Streams of pale gray poisonous miasma slowly emerged from the center of this triangular circle.

"Xiao Du, can you see anything, is this some kind of poison refining array, refining toxins with the help of Xuanhuang Qi?"

Du An's divine sense emanated, carefully observing the magic circle, and his expression gradually became strange: "Although I have never seen this kind of pattern and material, the aura emitted has nothing to do with poison refining, but it is ...... Like a teleportation circle. ”

Pan Yan was slightly stunned, and his physical divine sense also poked out, scanned it a few times, and felt a trace of vague spatial fluctuations.

"You mean, the toxin was teleported from somewhere else?"

Du An hesitated and said, "It should be like this, but I am not proficient in the way of formation, so it is best to let the disciples of the Star Moon Pavilion come and study it." ”

Pan Yan nodded, and looked around again: "In addition to the poisonous gas, there is also Xuanhuang Qi gathered here. ”

The ground outside the triangular circle is a kind of dark yellow rock, which has become a special earth attribute material under the accumulation of Xuanhuang Qi for a long time, but it contains toxins, even if ordinary immortal cultivators get it, I'm afraid it will be useless.

On the wall behind it, a layer of dark yellow aura was densely arranged, which seemed to be somewhat similar to that in the Demon Pool Cave.

"The Xuanhuang Qi is bred by a special leyline, the wall here has been transformed, it is likely to be related to the topography of the Demon Dragon Mountain, Senior Brother Pan, I think it is better to ask the pavilion master to come over in person." ”

Pan Yan muttered, "Wait until we finish exploring the rich points of the other Xuanhuang Qi, and then report to Master." ”

"Only the source force field of the master and his old man can bring more Xingyue Pavilion disciples here, let's go, let's continue to explore. ”

After speaking, Pan Yan took Du Yin behind him, and with the help of the power of the advanced earth escape technique, flew to the top of the rock above and disappeared.
