The closer Qin Fen got to the entrance of that cave, the more he could feel an extremely violent force, not like man-made, but... Born of heaven and earth!

Throb!

This unusually violent force moved Qin Fen's heart and gave him an inexplicable throbbing.

He had slapped his face in the Medicine King Valley like this before, and no one showed up to stop him, and as soon as he came to this cave, there were many old immortals who were extremely not weak in cultivation.

It seems that he can't go to this 'strange' place.

"Whew!Whew!"

Suddenly, three more people appeared in front of him, gorgeously dressed, with white hair all over their heads, and their momentum was extraordinary, seeing that Xiu Wei was already a monk who had entered the Martial Dao Golden Pill with one foot.

"Who?"

Qin Fen suddenly stopped his rapid galloping footsteps and asked suspiciously.

"Dan Chengzi, the valley master of the Medicine King Valley, the old man advises you to leave quickly, otherwise the three of us will be here next, where can you be presumptuous?"

Dan Chengzi stood with his hands in his hands, his snow-white long beard fluttering in the wind, if it weren't for the almost invisible hole on his body that was burned, maybe Qin Fen would have really believed his nonsense.

"You've finally appeared, old man, but I don't seem to have much interest in you now, but the hole behind you... Very interested!"

Hearing this, Dan Chengzi's expression suddenly changed, and the qi and blood all over his body also surged at this moment, making him feel like a big sun.

"Since that's the case, there's nothing to say, then let's fight, arrogant boy, just let you taste the secret technique of fire control in my Medicine King Valley!"

After finishing speaking, a fiery dragon with blazing flames appeared around Dan Chengzi's body, wrapping around him.

"Fire Spirit, up!"

"Roar!"

Immediately, with a high temperature that seemed to be able to melt iron and stone, the fire dragon suddenly roared.

"Yohe, this year, there are still people who dare to play fire control in front of the master?"

Qin Fen immediately laughed, laughing very presumptuously.

In the past few months of penance in the cave, if it is said that it is cultivation, he may not have much growth, but when it comes to this fire control technique, he has already reached the peak realm under the teaching of the medicine world, not to mention the old man in front of him, even if King Dan comes here, he is not his opponent.

Immediately, Qin Fen pinched Xuan Ao's fire control seal and hit the fire dragon that was attacking him, thus branding the mark that belonged to him.

And the fire dragon in front of him was already a plaything in his hand, and the traces left by Dan Chengzi were suddenly wiped out.

"Nice fire spirit, but it's mine now. Qin Fen chuckled at the corner of his mouth, and with the continuous fire control marks on his hand, the fire dragon immediately became furious and restless.

"Go ahead, don't let me down!"

As soon as the words fell, the fire dragon suddenly turned around, thus sweeping the blazing temperature and attacking towards Dan Chengzi.

"Damn, damn it!"

Immediately, Dan Chengzi cursed secretly, but he soon had to react.

Medicine King Mudra!

The secret of the medicine king valley's fire control, in this move, there are endless legends that belong to it.

Dan Chengzi is worthy of being the current owner of the Medicine King Valley, and his one-handed fire control technique is really perfect, and he can actually block his fire control technique in the front, which is really interesting!

Qin Fen squinted his eyes slightly, and constantly made countless medicine god handprints in the air on his hand, this move is naturally extraordinary, if the medicine king handprint in the Medicine King Valley is the earth, then the medicine god handprint in Qin Fen's hand is the sky.

The word God of Medicine alone was enough to repel countless alchemists.

Qin Fen's hand speed was very fast, and the countless handprints he pinched out immediately defeated Dan Chengzi's Medicine King Handprint head-on, and he still had the strength to control the fire dragon, and the three people who blocked him in front of him in an instant turned into ashes!

"If you want to stop me, then you have to see if you have the ability to do it?"

He said with a look of disdain, and walked straight towards the hole.

Speaking of which, this hole was made by the fool in the first place, but what is the purpose of doing this?

What good is it for them to expose themselves in this way?

Along the way, Qin Fen was very careful and cautious, for fear that if there was a case, he would lay some traps and forbidden things for him, which would be very unfun.

All the way down, his downward speed is very slow, it can even be said to be turtle speed, that is not too much, only when he is completely sure that there is no danger going down, this will slowly move down a small step.

Along the way, Qin Fen also found many abnormal things, that is, the further down he went, the hotter the temperature became, and he had only descended a distance of hundreds of meters until now, and his clothes were all wet with sweat.

What the hell is going on down there?

After descending hundreds of meters, Qin Fen actually felt that the skin on his body had a burning sensation, you must know that his physical body was not a simple thing, but it was shaped by the Demon Ancestor himself, even if the surrounding environment exceeded the high temperature of thousands of degrees, he did not scream.

But at the moment... But for the first time, he felt a burning sensation that he had never felt before, could it be that the temperature below was already more than a few thousand degrees?

No wonder, those monks before had a little hole in their bodies, and they dared to wait for him in this stubble!

At the same time, he also understood that there must be something extraordinary underneath this, Qin Fen seemed to hear this call faintly, very softly.

However, the more this vision appeared, the more he could not make mistakes, and in the face of such high temperatures, if he could not resist with his physical body alone, he immediately sacrificed the true fire of Samadhi, and instead formed something like a protective shield to protect his body.

This is not the end of it, and then his divine consciousness is like an ocean, and it suddenly swept away, so that if there is any danger, he can also know it as soon as possible.

For this kind of unknown place, everything else is false, and only if you protect yourself, that is true.

This time, he was not as careful and subtle as before, and the speed at which he rushed down was naturally much faster, but to be honest, the hole was indeed very deep, and he descended for half an hour before reaching the bottom.

But Qin Fen, who saw the scene in front of him, was stunned immediately, the area in front of him was all dark red magma, exuding an extremely high temperature, if it weren't for the sound of magma bubbling from time to time, Qin Fen might still be in a shocked expression.

This is a world of magma, but is there only a few people?

Didn't those disciples say that there was an ancestor of the Martial Dao Jindan, and now where did that ancestor go?
