The bastard patiently explained the role of the black yao stone, and after Murong Bai heard it, his heart suddenly burst into joy, and then his eyes flashed, and he decided to divide the black yao stone into two pieces and make a ring, one for the free city, and the other for himself.

Murong Bai looked intoxicated, as if he had entered a fantasy. 『』

"Boy, dig up, it's almost to the bottom!" the bastard reminded with a pout.

"Ahh

The bastard's words are really good, Murong Bai dug for a while, then dug through, leaned along the stone cave, and poked forward, hey, I saw a huge karst cave below.

This cave is red all over, and even the stalactites hanging upside down on the top of the cave are all red and clear, shining brightly, reflecting the whole cave.

Murong Bai grunted, jumped down from the stone cave, and looked around.

"Go to the left. The bastard spoke, and there was a hint of excitement in his words.

Murong Bai carried a black big knife and walked towards a huge cave on the left, and when he walked in, Murong Bai found that the cave that was enough to pass through two carriages was all red, and the stone walls on both sides seemed to be inlaid with countless huge red gems, which made people can't help but want to touch it.

But as soon as Murong Bai wanted to stretch out his hand to touch the stone wall, the bastard shouted: "Boy, you don't want to live anymore, the red stone on this stone wall is a fungus that has been petrified for hundreds of millions of years, although it has been petrified, but if you touch it, you will definitely be injured by the fungus poison in it, and even if you use the old man's cultivation back then, if you want to save you, you will have to spend a lot of trouble." ”

"I'm going, fortunately you reminded me, otherwise I wouldn't know what was going on, so I went to report to the underworld. After Murong Bai secretly stuck out his tongue, he didn't have any distractions, took a step, and walked directly towards the depths of the cave.

This red cave is not too long, Murong Bai walked out not long ago, but when he stepped out of the cave, Murong Bai was so shocked that he could stuff eggs in his mouth.

I saw that there was an underground river five or six zhang wide in front of me, and the water flowing was all gray-white, and on both sides of the gray-white river, there were unknown red plants.

Murong Bai was completely stunned by the scene in front of him, and he couldn't imagine that there was such a strange scenery in the depths of the earth.

"Bastard, why is this river gray-white?" asked Murong Bai.

"It's not water at all, it's slow-flowing limestone!" the bastard responded.

"I'm going to go, obviously there are still waves on the river, how can it be white limestone?" Murong Bai was puzzled.

"You take a stone and throw it in. The bastard pouted.

Murong Bai tried it, but when the stone thrown out fell on the white river and did not sink, Murong Bai was even more shocked and speechless.

"It's not a big deal, these limestones have been burned by the fire dragon veins... You can walk along this limestone river now, and you will find the location of the Earth Fire Dragon. The bastard began.

Murong Bai suppressed his surprise, carried the black big knife, and walked along the river bank, all the way through the thorns and thorns.

There was silence all around, only Murong Bai was alone, walking among the red grass and trees.

After walking for about an hour, Murong Bai turned around along the river bank, passing through several stone caves, and then gradually came to the end of this white limestone river.

I saw that not far ahead, there was a red mountain peak that was not high, and there was a three-zhang tall red stone gate at the bottom of the peak, and below the red stone gate was the end of the white limestone river.

"Why is there a stone gate here?" Murong Bai felt very strange.

"This must have been forged by the ancestors of the previous generation of Xiaoyao Villa, and I think that the inside is where the fire dragon vein is located!" the bastard's tone began to become eager.

Murong Bai glanced around, and after not finding anything abnormal, he picked up the black big knife in his hand and strode forward.

The red stone door had not been opened for a long time, so it took Murong Bai a lot of effort to open a crack in the door that only allowed one person to pass through guò.

Murong Bai squeezed over, and after walking through a long and narrow red cave passage, he saw a purple-red cave appear in front of him, and at the same time, a wave of heat rushed towards him.

Murong Bai hurriedly took out the red umbrella and held it in front of him, not to mention, after the red umbrella absorbed the heat wave, it suddenly shot out a red pillar of light, directly enveloping Murong Bai in it.

With the defense of the red umbrella, Murong Bai's mind calmed down a little, and he immediately stepped into the purple-red cave.

There was a huge purple altar in the center of the cave, and a thick red flame shot out from the altar, and this red flame rose directly, like an upside-down red waterfall, directly into a red cave at the top of the cave.

The altar was empty, except for countless streamers of fuchsia that shone forever.

"Tsk, it's not a loss to an alchemy family, this dragon formation is very ingenious. The bastard couldn't help but admire

"Bastard, don't be busy praising you yet, you have to think of a way, how can you absorb the earth fire!" Murong Bai urged.

"You take a look around the altar first, and the old man ponders carefully. The bastard was lost in thought.

Murong Bai did as he was told, took small steps, and circled around the altar, and Murong Bai carefully looked at the purple altar as he turned.

I saw that there were four red Vermilion Bird birds flying around the altar, and what made Murong Bai curious was that the blue eyes of each Vermilion Bird on the altar seemed to be alive.

After walking a few steps, Murong Bai suddenly found that no matter which direction he turned, the blue eyes of the Vermilion Bird were always staring at him.

"It's really weird!" Murong Bai muttered to himself.

"Boy, this dragon leading array is endless, if you want to absorb the earth fire without destroying the formation, it is almost impossible to do it, but you can open a hole under the altar, remember that the hole should not be too big, just be able to absorb the earth fire into the body. The bastard thought about it for a long time before he came up with such a solution.

"Okay!" Murong Bai was quite helpless, since he dived underground, he had been living like a gopher, and he had been burrowing, and it was not bad this time.

Murong Bai put the red umbrella on his head, held the knife in both hands, and stabbed directly at the ground under the altar, opening a hole the size of a bowl, and then continued to dig deeper.

When he dug about a zhang, Murong Bai raised his hand and sent out a beam of spiritual energy, and after retracting the black big knife at the bottom of the cave, a red flame with the thickness of the mouth of the bowl suddenly shot out
