Just as Chen Feng's spiritual power was constantly searching in the Ancient Cave Mansion, he suddenly let out a light sigh, and his gaze was fixed on a relatively ordinary wall, because this wall was able to block his spiritual power.

You must know that Chen Feng is a top-level array master at the extremes of life and death, and his spiritual strength is much stronger than the soul power of ordinary powerhouses in the polar realm of life and death, and he was actually blocked by this wall, which made Chen Feng a little surprised.

"According to the exploration of my spiritual power, the material of this wall is essentially different from the walls of other places, and it can also block the effect of spiritual power, obviously this is deliberately designed by the owner of the cave, so in other words, there must be something different behind this wall. ”

Thinking of this, Chen Feng's eyes suddenly became bright, and his eyes stared at the wall in front of him.

After looking around and finding that no one around him noticed his abnormality here, Chen Feng approached the wall in front of him quite cautiously.

Knock knock!

Knocking lightly on the wall a few times, a crisp sound like the symphony of gold and iron sounded, which made Chen Feng nervous.

"Sure enough, this is an unusual sound, which is not something that ordinary walls can make. Chen Feng rubbed his chin and said lightly.

"I'm going to try to break through this wall and see what is hidden on the other side?"

As he spoke, Chen Feng didn't drag the mud and water at all, only to see his steps wrong, his waist and hips were united, the soles of his feet stepped forward violently, and his right fist, which was ready to attack, slammed into the wall like a blazing golden mang.

Rumble!

A low voice suddenly spread, and then Chen Feng was shocked to find that the wall under his fist actually didn't move at all, and even the same recoil force acted on his body.

Pedal Pedal Ped

Suddenly taking a few steps back, Chen Feng's brows furrowed slightly, and he said quite solemnly: "It's such a hard wall, my attack actually has no effect at all." ”

The loud rumbling sound on Chen Feng's side also attracted the attention of some martial artists not far away, and then these martial artists glanced at each other, and they all swept towards Chen Feng's side.

However, when they saw Chen Feng staring at a wall in a daze, a trace of disappointment suddenly appeared in the eyes of these martial artists, obviously they thought that someone had found a treasure, but they didn't expect to see the monotonous picture in front of them.

After cursing a few words of retardation, the warriors scattered again and began to search the other stone chambers to see if there were any treasures or anything like that.

Looking at the martial artists who scattered again, Chen Feng secretly breathed a sigh of relief, fortunately, this weird wall was hard enough, otherwise if he really broke the wall, I am afraid that these martial artists who heard the sound would come to fight like mad dogs.

"Alas, I can kill the late stage of the Enlightenment Realm with one punch just now, but I still can't pose any threat to this wall, it seems that I can only try it with the Black Mist Domain," said Chen Feng and slowly took out the palm-sized Black Mist Domain from the Qiankun bag, at this moment, the black qi on the Black Mist Realm was flooding, and the aura was extremely violent, it seemed that there was a desolate beast hidden in the Black Mist Realm ready to attack.

"It seems that the Black Mist Realm is about to cross the rhythm of the tribulation," Chen Feng said with a secret sigh.

In fact, after the Black Mist Realm devoured the Star-Devouring Realm, he realized that something was wrong, and now it seems that this Black Mist Realm should be about to cross the Tribulation Tribulation.

However, Chen Feng knew that this Black Mist Realm was still accumulating strength at the moment, and it would not be a catastrophe for a short time, so he took it out.

Immediately, Chen Feng's right hand slashed into the void above the black mist realm, and an inky black mist suddenly spread, and it became more and more viscous like a liquid.

The black viscous liquid soon stuck to the wall, only to hear a slight clanging sound, and then Chen Feng was surprised to find that the seemingly indestructible wall actually slowly melted under the black viscous liquid, and was finally corroded out of a hole the size of a human head.

"Let's take a look!"

Seeing that the wall had corroded a hole, Chen Feng couldn't wait to take a closer look, and soon he found that the space behind the wall was not large, at most it was as big as a person standing, and it was even darker inside.

However, with the assistance of spiritual power, Chen Feng naturally explored the situation inside.

"This is ......" Chen Feng sighed lightly, and then a strange look appeared on his face.

I saw Chen Feng's heart move, and under the traction of spiritual power, two black shadows suddenly flew out from the entrance of the cave, and as soon as he reached out to catch them, he caught these two black shadows.

"This can't be the map of the Ancient Cave Mansion!"

Picking up a piece of yellowed paper, Chen Feng spread out his hands and unfolded it, looking at the somewhat complex structure diagram on the paper, Chen Feng's eyes suddenly burst into essence.

Chen Feng took the map in his hand and looked at it, and he also saw the stone gate marked on the map, as well as the complicated palace route marked on the map, obviously this map must be the map of the cave mansion.

He even saw the overall structure of the Ancient Cave Mansion on the map, as well as some hidden traps.

"Then could this key be the key to a secret room in the cave?" Gently closing the map, Chen Feng picked up a key the size of a palm and muttered.

The surface of the key is covered with white markings, which looks like it is carved out of stone, and a faint fluctuation is revealed from the stone key from time to time, revealing its extraordinary.

Chen Feng naturally knew that the key in his hand was not ordinary, and it was likely to be of great use in the depths of the Ancient Cave Mansion, after all, the owner of the Cave Mansion would not hide a useless key in such an inconspicuous place for no reason!

"Since I have a map, then I can go to the location of the medicine garden in the cave house first, and now the top priority is to find the thousand weak flowers first, Si Ting's condition cannot be delayed. ”

After speaking, Chen Feng put away the key and the map, turned around and swept straight towards the depths of the passage, just now he had a cursory look at the content of the map, and had already determined where he was now.

In the introduction of the map, there are two medicine gardens in the cave, one medicine garden is in the deepest part of the cave, the area is thousands of miles wide, and there are countless medicinal materials in it.

The other medicine garden is just a test site, the area is not large, only about a hundred miles, but there are also a lot of medicinal materials in it, I think there should be a thousand weak flowers that Chen Feng needs in it.

And what Chen Feng plans to go to now is the experimental medicine garden, after all, judging from the map, that medicine garden is much closer to his current location, and the danger is much lower.

After all, the deeper you go into the cave, the more numerous and dangerous the traps inside become, and there may even be some powerful ancient beasts.
