Looking at the traces on the ground that exuded a little bit of green, Lin Tian and all of them's eyes were uncertain, and countless thoughts passed through their hearts.

The poison contained in this is so fierce that even Yang Yuesong, a master of the second layer of the congenital layer, was already poisoned by just a light touch.

Moreover, transporting all the innate true qi in the body, he couldn't force that poisonous gas out of the body, and he also needed the help of Elder Zheng, a master of the late congenital stage.

Elder Zheng could only force the poison together, and if he wanted to go further, it was impossible, so he could only cut off the whole piece of flesh and skin.

Poisons that can harm innate masters are very rare, not to mention the poisons that even the masters of the late congenital stage can't suppress, and they are even rarer, all of which are extremely precious.

There must be no such poison in this cave, otherwise, it would be impossible for Xuantian Sect not to know, so it can only be left behind by the murderer who ransacked the spirit stone mine.

It seems that in the process of searching in the future, everyone should be more cautious, otherwise they will be invaded into the body by this poison, and their lives may be lost.

After all, even the toxicity of this little residue is already so ferocious, if they are really hit by the poison, this puddle of pus in front of them will be their end.

After carefully investigating the surroundings, they didn't find anything other than this trace, so Lin Tian and the others continued to go deeper into the cave.

In the following journey, Lin Tian found several miserable green traces one after another, and it seemed that the masters of the sect who guarded this vein had all been killed.

Moreover, judging from the other traces left at the scene, those masters did not have the slightest room for resistance, and they all turned into pus in an instant.

After perceiving this, Elder Zheng's face became even more ugly, with a gloomy expression, and a fierce chill emanated from his body.

And Lin Tian's minds were all raised, and if they could kill so many masters in an instant, they must be a master who has gone very far in the innate realm.

If they were to be alone, it would be a very dangerous thing, and they had to be less cautious and use all their energy to deal with the attack that might come at any time.

However, there was no danger along the way, except for the traces of the road, there was not a single figure, only endless darkness.

After a while, Lin Tian and the others finally came to the bottom of the cave, but the situation in front of them made Lin Tian and the others suddenly taken aback.

I saw that on the wall of the cave that was thirty or forty zhang wide and more than ten zhang long, there was a circular cave with a width of more than five zhang out of thin air, as if it had been specially carved, the light was straight and straight, and it was incomparably round.

Looking at the traces of the hole, there was no round hole in the first place, it should have been dug out by something in the last few days.

Suddenly, Elder Zheng suddenly stretched out his right hand, five fingers and one finger, and sent out a strong suction force from his palm, aiming at one direction and shooting away.

In the blink of an eye, a palm-sized jade plaque flew up from the ground in the distance, and with the slightest sound of breaking through the air, it flew towards Elder Zheng, and instantly appeared in Elder Zheng's hand.

After Lin Tian noticed these movements, he quickly looked towards Elder Zheng, and immediately, he saw the jade plaque he was holding tightly in his hand.

After seeing the jade plaque, Lin Tian and the others were shocked again, this kind of jade plaque had a piece in each of their hands, except for the pattern on it was a little different, it was no different in any other aspect.

Lin Tian and the others knew that this was the elder token of the Xuantian Sect, and those who could possess this kind of jade plate were all the inner sect elders in the Xuantian Sect, and their cultivation had reached at least the middle stage of the innate stage.

Now that this jade plaque has appeared here, come to think of it, the elder of the inner gate is already more than lucky, and the damage has fallen in this vein.

Elder Zheng's face was gloomy, he looked at the jade plate in his hand, and with a thought, he put it into his storage ring, and then focused his gaze on the round hole that suddenly appeared.

After a slight mutter, Elder Zheng led Lin Tian and them to quickly fly into the round hole, and disappeared into the cave in an instant.

Lin Tian and the others quickly passed through the cave, only to see that this cave was very straight, the same circle from beginning to end, without the slightest change.

Moreover, there is not a single gravel on the cave floor, and it is not known where the remaining stones have gone after the cave has been excavated.

The more he walked inside, the more intense the aura around him became, and some crystalline spirit stones gradually appeared on the surrounding cave walls, as if he had come to the center of this spiritual mine.

However, Elder Zheng's expression became heavier and heavier, and finally, it seemed to be covered with a thick layer of frost, and even the speed of his footsteps became faster and faster, with a series of phantoms, shooting towards the depths of the cave.

After a while, everyone finally came to the end of the round cave, which was a cave that was a hundred feet square, which should have been naturally formed, and countless spars grew on the stone walls, emitting a faint light.

However, those hedrons were covered with countless tiny cracks, as if they would shatter at any moment, and they looked like they were broken.

Seeing the scene in this cave, Elder Zheng couldn't hold back any longer, and let out a long howl from his mouth, which contained infinite anger, surging back and forth in the cave.

The whole cavern shook with this loud bang, and the boulders fell from the stone walls and slammed into the ground, and the crystals exploded with a thud.

Lin Tian and Wu Haolan also looked at each other, and a monstrous wave was set off in their hearts, and they couldn't calm down at all, and their expressions became extremely serious.

It's no wonder that Elder Zheng is so mad, because this cave is the core of this spirit mine, you must know that there is a mine core in the center of every spirit mine, which contains an extremely rich and pure aura, and has an extraordinary mystery.

As long as the ore core is not destroyed, then this ore core will swallow the aura of heaven and earth on its own, gather the infinite aura between heaven and earth, and generate countless spirit stones in the ore vein.

As long as the excavation does not exceed one limit, then a spirit mine will not be exhausted at all, and it can always provide a large amount of spirit stones for the sect.

But in front of him, it is obvious that someone has opened up the mine core, absorbed all the aura contained in it, and destroyed the mine core.

This means that this spiritual mine has been completely abolished, which is also a very big loss for the Xuantian Sect, which is enough to make the top of the sect feel painful.
