The black gas was swirling, the flesh and blood on the young man's body were instantly peeled off, Gu Fan's eyes became cold, and a deep uneasiness appeared in his heart, this black qi was clearly absorbing flesh and blood.

And not let people above the battle master come in, maybe because for the time being, this black qi can only absorb the flesh and blood of the war division level, but why should it absorb flesh and blood, this reminds Gu Fan of the war spirit in the secret realm outside the sword gate, it is very likely that some kind of existence uses the black qi to devour the flesh and blood in order to achieve the purpose of rebirth.

Combined with what Beichen said, this is completely possible, after a long time of baptism, even if it is a character like Beichen, flesh and blood will die, and this existence has been suppressed by the Beidou Sect.

Immediately, there was a trace of jealousy in Gu Fan's eyes, if this was the case, this place would become extremely dangerous, but there was also a good thing, if this black qi only absorbed the flesh and blood of the Battle Master Realm for the time being, Yu Xin and the others would definitely have a chance to survive.

Immediately, Gu Fan glanced at the blue ring in his hand, rubbed it slightly, and said, "Whether you can find Yu Xin or not depends on you!"

The Blue Ring let out a tremble, and a faint light appeared, and Gu Fan followed this light and slowly approached the center of this ruin.

The sky is dark, due to the shroud of black gas, it is impossible to tell whether it is day or night outside at this moment, and a corpse can be seen everywhere on the road, it seems that it should be a person from the Beidou Sect, and the bones are wrapped with some black gas, which makes Gu Fan very concerned, in this kind of blocked ancient ruins, everything must be careful, it is like a battlefield that covers the sky, and if you take a wrong step, you may start some kind of prohibition.

But fortunately, unlike the battlefield that covers the sky, Gu Fan is armed with the seven-star sword, and it is smooth sailing in this ruins, once there is any prohibition in front of him, the seven-star sword will give the first warning, so that Gu Fan can avoid smoothly, and gradually, Gu Fan followed the guidance of the blue ring to a ruined hall.

"Here, it should be the Alchemy Hall of the Beidou Sect. Gu Fan looked at the hall in front of him, there was still a vague medicinal fragrance floating in it, obviously there was some kind of medicinal material in it, Yu Xin and a few people came in to hunt for treasures, and it was understandable to enter the Medicine Refining Hall, but Gu Fan wondered that the Seven Star Sword did not issue any warning, which indicated that there should be no kind of prohibition outside the Medicine Refining Hall.

But Gu Fan only took a step, and he felt a chill to the bone, this alchemy hall was definitely not as simple as it seemed.

"There is a medicinal fragrance, it seems that we have come to the right place!" There were several voices coming from behind Gu Fan, and he didn't need to look at it to know that the others had already followed, smelling this medicinal fragrance, everyone was excited, after all, how could an elixir that existed and immortal since the time of the Beidou Sect be mortal.

But soon, they saw Gu Fan standing in front of the alchemy hall with a solemn face, and their footsteps couldn't help but be stunned, could it be that there was something wrong?

For a while, everyone was discouraged, Gu Fan's eyes at the moment were condensed with golden light, staring at the alchemy hall in front of him, the induction of the seven-star sword was right, there was no prohibition around this alchemy hall, but there was a faint black gas under the earth, but Gu Fan could clearly feel the cold chill, and still did not move.

The rest of the people also used their own means, and the results of the investigation were the same, there was no danger outside this alchemy hall.

Immediately, a person gritted his teeth and walked over, the cultivation of the Seven Star Battle Master Realm was not bad, after confirming that there was no danger in the Medicine Refining Hall, how could it be that after being weaker than others, it was true to get the elixir.

Many people watched someone take the lead, all of them rushed up, and the scene became extremely chaotic for a while, but Gu Fan's face changed, and he involuntarily took a step back, and the rest of the people also looked at this group of people who rushed over like crazy people without saying a word, there are still people who have come in here besides them, if there is really no danger, this door has already been opened, how can it be their turn, and now it is the most correct choice to watch coldly.

Several people approached the gate without any obstacles, and their faces were full of joy, it seemed that they were scared of themselves, but anyway, they had already won the first place, and the anti-heaven elixir in it would definitely have a much greater chance than others.

But Gu Fan felt a chill at the moment, and the ground under his feet actually shook slightly, and when he found a situation, Gu Fan's figure immediately burst out, and the steps in the sky were all used, and the rest of the people who saw Gu Fan's movements also changed their faces, and naturally they also discovered this change, and immediately rose into the air.

Suddenly, a small voice came out, and everyone who approached the Alchemy Hall thought that the door had been opened, but only the nearest person's face turned pale, and he knew that he hadn't pushed the door at all, and this voice definitely didn't come from inside the Alchemy Hall, but from his feet.

Gu Fan, who was retreating, also heard a strange voice, and immediately his face sank, looking at the ground under his feet, there were actually slight cracks, "It's here!"

As soon as the words fell, a miserable scream sounded, and in the ground under his feet, a skeletal hand wrapped in black gas stretched out, and grabbed the leg of a six-star warrior, and suddenly the black qi was swirling, and the flesh and blood instantly peeled off as if it was rotten, revealing the white bones in it.

The screams attracted everyone's attention, and they all changed their faces and hurriedly retreated, naturally no one would be kind enough to save people in this kind place, and in an instant, the screaming man was swallowed up by the black gas, leaving only a skeleton unwilling to fall to the ground.

Everyone suddenly gasped, and there was a commotion in the crowd, but one by one the skeletal hands continued to stretch out from the ground, and the people who caught them were all swallowed by the black qi, and almost instantly, the people who were close to the alchemy hall were all wiped out, and not even a trace of flesh and blood was left.

"It's really a good way to use black gas to control skeletons, if you weren't careful, you would really be on the road. Gu Fan's face was gloomy and he muttered to himself.

This existence seemed to have expected that there would be people with the relics of the Beidou Sect coming in, so the prohibition of the Beidou Sect was removed outside the Medicine Refining Hall, so that the Seven Star Sword could not be sensed, and if the previous Gu Fan went further, I am afraid that he would end up with the same fate as these people.

Click, click, click... Voices continued to come out, and Gu Fan looked at everything that happened in front of him, and his face turned blue in an instant.
