The terrifying rumors of fiery fire poison have been around for a long time, and all spiritual realm cultivators have heard of it and are in awe of it.

However, for mortal realm cultivators, the horror of the fiery fire poison would only be reflected in the extent to which it had accumulated in the cultivator's body, and those in the middle would hardly have any possibility of survival.

As for the degree of damage and harm to the minds of mortal realm cultivators, it is not fatal, and it only needs a period of recuperation and patience for mortal realm cultivators to eradicate it under the means of alchemists.

Of course, in this process, mortal realm cultivators must endure the severe pain of the cone caused by the Blazing Fire Poison for a long time, and as long as they keep themselves from being tempted to die by this severe pain, they can survive in the end.

As for the price of surviving, either the cultivation has declined and there is no further existence, or the mind is damaged, and it is impossible to break through to the spiritual realm in the rest of his life.

However, spiritual realm cultivators with spiritual consciousness are different, although it is not an exaggeration to say that spiritual consciousness is in the same vein as mortal realm perception, but the difference between the two is also extremely obvious.

No matter how powerful the perception of a mortal realm cultivator is, the point that can be improved will not change before he undergoes transformation, and its essence is still a formless and substantiated thing, how can the existence of this form be fatally injured by the fiery fire poison?

Spiritual consciousness is different, it is a special power transformed by the perception of mortal realm cultivators and the power of heaven and earth, which has been transformed from formless and insubstantial to qualitative things, and even for some spiritual realm practitioners who are proficient in this path, they can easily control their spiritual consciousness, and through the change and transformation of their minds, they can form various aggressive forms, and it is not an exaggeration to say that they are tangible and qualitative.

If you think about it, ordinary firewood in the mortal world can burn tangible and qualitative things, not to mention this terrifying fire poison that can be said to be born for the spiritual consciousness of spiritual realm cultivators.

Of course, the Blazing Fire Poison is so terrifying, naturally there will be no shortage of cultivators with ulterior motives, coveting its power, and eager to control its power.

It's just that its power is too terrifying, and it also causes that there are very few traces of fiery fire poison in the cultivation world, and only occasionally three or two rumors about it will circulate, and then it will end up without any trace of it.

Although there were many people in the cultivation world who imitated the environment in which it was born in order to cultivate the Blazing Flame Poison, and even conducted many experiments in the places where it once existed, without exception, these people ended up failing.

Even if three or two cultivators succeeded in cultivating fire poison by chance, it would only be a plausible new type of fire poison, not only far from the real Blazing Fire Poison in terms of power and effect, but also completely devoid of any similarities in form.

Taken together, this is all because the conditions under which the Blazing Flame Poison can be born are so confusing that no one can fully understand the complexity of it.

Not to mention that there are very few places that can meet these conditions, let alone cultivating when the practitioner has only heard and knows nothing, it is just looking for the right one among the countless possibilities, which is tantamount to looking for a needle in a haystack.

However, the development of the cultivation world is extremely long, and in such a long period of time, what these cultivators have done will not be without any gains, and after the accumulation of time, they will eventually summarize the birthplace of the Blazing Fire Poison into the most likely two.

One of them is that like other fire poisons, it needs a place with strong firepower, and after hundreds of thousands of years of accumulation, it may have a chance to be born.

The second type seems very absurd and bizarre, and in the eyes of many people, it is even more fictional, and there is no basis at all.

That is, after a long period of investigation, they realized that the appearance of the Blazing Fire Poison was actually related to a fiery elixir that had long disappeared in the cultivation world.

As for the specific effect of this fire-based elixir, the only description is very vague, and there is only a false name that has been handed down, so that its real existence has not been proved so far, so people will think that it is only a fictitious existence.

As a first-order alchemist, Yi Chen naturally would not make judgments, combined with what he saw and felt in front of him, he was actually more inclined to this place is the first situation.

So when he thought of this, Yi Chen's mood couldn't help but be heavy, and he realized that the danger of this trip was far beyond their estimates.

If it was really as he thought, the more they went deeper underground, the more poisonous the fiery fire poison that had accumulated under this crater would only become more and more intense, and the two of them would become more and more dangerous.

"What are you doing standing here, go ahead and find your way, or you'll all be like him."

"Hmm.... Save.... Help me."

A contemptuous voice came from behind him, interrupting Yi Chen's thoughts.

At the same time, as he came back to his senses, a small knife with a flickering cold light passed by his ear with a piercing sound of breaking through the air, and pierced into his brow in the stunned eyes of the cultivator who covered his head and howled, and he fell to the ground and died after only a few struggles in front of everyone's eyes.

After the person's body fell, the surrounding heat seemed to sense the presence of true qi and swarmed into the person's naked body.

In just a few breaths, the man's body quickly shriveled up into a centuries-old corpse under everyone's horrified expressions.

In the end, in the frightened eyes of everyone, a blazing red flame appeared from the position of the dry corpse dantian, enveloping the corpse in the blink of an eye, and by the time three breaths had passed, the dry corpse had been completely burned, and finally only a humanoid white powder silhouette was left on the ground, as well as a small cloud of gray-black iron pulp.

"This ..... What the hell is going on!?"

"Is it ..... It's the kind of fire poison that is legendary!?, no wonder..... No wonder .....".

All kinds of speculations suddenly spread from the panicked crowd, and many well-informed cultivators had already guessed a few truths, with obvious disbelief in the expressions on their faces.

"Hehe, it seems that you have guessed a little, if you don't want to die, go quickly, maybe you can still live from this damn air wall."

The speculation in their hearts frightened them, and the eyes of the people who looked at the invisible door gradually filled with blood, as if they had a desperate plan to fight, but after seeing Liu Hong, who was the last to step into the air wall, they could only secretly endure it and continue to move forward.

The heat in this wall of air was very strange because of the mixture of fiery fire poison, which could not only distort the cultivator's vision, but also isolate the cultivator's perception.

Although no one dared to release their perception to investigate, this was already guessed when they entered, after all, they could block their perception when they were outside, and they would only be more restricted in it.

This is not only that, it is also because of the existence of the fire poison, so Yi Chen did not feel the existence of a trace of heaven and earth aura from the space.

In other words, in the next time, they who opened the protective shield at all times wanted to replenish the true qi and true yuan in their bodies, and they could only recover by swallowing the pill.

After what happened suddenly, everyone knew that there was a danger they didn't know about, and in the case that the invisible door people were unwilling to inform, they could only be vigilant and move forward cautiously.

The speed at which they traveled was very slow, and the people of the Invisible Gate did not speed up much despite several urgings, so that for the next few hours, they only traveled nearly five hundred meters or so to the depths.

Although the distance was short, everyone's minds were tense to the extreme, especially the remaining rocks and a few shocking battle traces along the way, which made them desperately want to resist, but the presence of Liu Hong behind them made them have to interrupt this thought.

"It's ...... I can't imagine that they can already make enough preparations, and they can still let Han Qingye play such a role, which is worthy of being two major forces."

Since Liu Hong and the others entered, Yi Chen's mind had always been paying attention to the movements of the invisible door, one was to observe their actions, and the other was to see how they coped.

Seeing the pale cyan light permeating each of them, as well as the tiny phosphorescence that appeared on the surface of their skin, Yi Chen finally realized that this was actually another function of the cold clear liquid.

After three years of operation, the invisible door obviously already knew the mystery of this place, and was very aware of the dangers they were about to face, and it was likely that the purpose of exploring the way with them was only to eliminate some dangers that were difficult for them to judge.

With understanding, he will inevitably be prepared, before this, Yi Chen had always thought that the cold clear liquid only played an auxiliary role when collecting and taking the diyan liquid, but he didn't expect that the cold clear liquid could actually isolate the heat here, so as to exclude the blazing fire poison mixed with the hot gas from the body.

This was the first time he had seen this method, and if it weren't for the fact that he had personally refined the cold clear liquid, he was afraid that he would really use it as another method, which was really unexpected.

However, this is extremely important news for Yi Chen.

Not long ago, he had personally refined thirty copies of Hanqing Liquid, and although there was no trace of falsification in the medicinal materials in each of them, with his first-order alchemist attainments, and the fact that he had prepared before refining.

Therefore, if he wants to extract a few more copies of Hanqing liquid from the thirty parts without any surprises, there are not too many problems for him, the only thing that needs to be paid attention to is the amount of quantity, and the degree of influence on the medicinal effect of Hanqing liquid.

Thinking of this, Yi Chen couldn't help but sigh again about the correctness of using the cloak as a disguise, it was precisely because of this cloak that he would not let others notice his actions, which gave him the best cover for his next plans.

Carefully took out a small bottle of sealed green liquid from his arms, Yi Chen didn't think much about it, hid his movements, and quickly swallowed it, so that a big stone in his heart finally fell.
