Regarding the earth fire, Yang Dong still hasn't figured out what it is, he can only rely on his knowledge before crossing to speculate that it should be an underground volcano similar to the crossing lot, or natural gas, coal gas, biogas and other substances. Pen Fun Pavilion wWw. ｂiquge。 ｉｎfo

However, this thing doesn't seem to be exactly the same, it seems to have a sense of mystery, which is related to some mysterious energy, and in the end, Yang Dong can only say to himself that earth fire is a special substance in this other world.

The lava cave was relatively narrow at first, and only one person could slowly grope his way forward, but after a while, the lava cave gradually became open enough to accommodate Yang Dong and Xia Houjie walking side by side.

"Yang Dong, do you feel it, the temperature here seems to be a little higher now. ”

Xia Houjie asked.

Yang Dong nodded, he did feel a slight sweat in his body.

The gold mine cave is in the mountain body of the desert mountain, and some places are even hundreds of meters deep, which was originally dark and damp, and some are cold, but after entering this lava cave, it began to become stuffy.

In addition to the sweltering heat, the inside of the molten cavern was still pitch black, and there was no light in sight, so they could only rely on the miner's lamp in the hands of the two of them to illuminate it.

The two of them continued to walk slowly, and they didn't know how long they walked, the air in the lava cave began to become dry, and even slowly became hot, and both of them obviously felt the pressing feeling of the high temperature, and their bodies began to sweat.

"Boom, boom,,,"

The two of them suddenly stopped walking forward, and vaguely heard a roar in front of them, which continued to explode regularly, but listening to this sound, it seemed to be relatively distant, not like it was close in front of them.

"Master, haven't you ever been in an earthfire molten cave before, and it's the same as now?"

"No, the lava cave I entered before was not like this, it was generally tens of meters and hundreds of meters long, and there was this earth fire beast entrenched in it, there was a small hole in the lava cave, and the earth fire kept coming out, which was similar to the earth fire used by our refining weapon, and the earth fire beast was lying not far from the earth fire, and between breaths, the earth fire would enter the mouth of the earth fire beast. ”

"There are still monsters in this world that devour the earth fire, can't the earth fire burn the earth fire beast?"

"No, the Earth Fire Beast did not swallow the Earth Fire directly into its mouth, but before inhaling it into its mouth, it spit out a cloud of white mist, dissolved the Earth Fire in the white mist, and then swallowed it into its body, absorbing the energy of the Earth Fire for its own use. ”

"But now that we've come such a long way, it seems that there is no end to it, and we haven't encountered the Earth Fire Beast, what is the sound of the roar in the distance?

"No, I don't have much research on the Earthfire Molten Cave, just keep walking, and you'll know when you get to the end. ”

"Will you encounter a particularly perverted Earthfire monster that is beyond the ability of the two of us?"

"Alas, don't scare the master, I still have to rely on you to fight the ,,, of the fire beast"

When Yang Dong heard this, his legs were weak, and he almost didn't trip and fell to the ground.

What kind of master am I worshipping?

Xia Houjie seemed to guess Yang Dong's thoughts, and smiled.

"The master leads the door, and the cultivation depends on himself, as you said yourself, the master is not necessarily stronger than the disciple, besides, the master is old and weak,,,

"Okay, master, don't say it, I'll show you the way in front, and if there's any danger, you can run back immediately,,,"

"I'm not such a righteous master, in case you are going to encounter difficulties, I will still try my best to help you take care of the aftermath, by the way, are you married? You should have a child early, but the master has no daughter, or I will recruit you as a son-in-law,,,

Yang Dongjue, when did Xiahou Jie become a chatterbox!

Yang Dong didn't bother to pay attention to Xiahou Jie, because he couldn't chat with him properly, how could this Xiahoujie, who was originally a very honest person, become so slippery now?

Disrespectful for the old!

The two of them continued to walk forward, the temperature inside the molten cavern getting higher and higher, and the roar getting louder and clearer.

Yang Dong had already taken off his coat, leaving only a thin green shirt.

Suddenly, dozens of meters away in front of them, a bright light appeared, and both of them trembled in their hearts.

Yang Dong glanced back at Xiahou Jie.

Xia Houjie also reminded vigilantly, "Be careful." ”

The two of them walked cautiously, and when they gradually approached the light, they realized that it was an exit from the lava cave, but the exit of this cave was not leading outside the valley, but was still in the cave of the Great Desert Mountain.

The light was not natural light, but orange-red firelight.

"Boom, boom,,,"

The roar came and went, like the waves of the sea.

The temperature is getting higher and higher, and both of them are drenched in sweat all over their bodies, and even their breathing is a little short, and they feel that what they inhale into their bodies is not air, but fire, and what they exhale is also fire.

The two extinguished the lamp and quietly walked to the entrance of the cave.

And then

The two were stunned.

What was presented in front of the two of them was a very shocking picture, hundreds of meters below the vertical distance from the entrance of the cave, there was a huge magma earth fire lake, and the huge earth fire rose from the magma earth fire lake from time to time, and disappeared in the air at a height of tens of meters, and the rumbling sound they heard came out of the earth fire lake.

In the sky above the entire Earthfire Lake, there were red flames rushing towards the rock walls hundreds of meters high, like red smoke.

The red glow of the fire was emitted from the lake of earth fire.

This cave entrance was at least a few hundred meters away from the Earth Fire Lake, and near the cave entrance, Yang Dong felt extremely hot, he couldn't imagine how high the temperature was there near the edge of the Earth Fire Lake.

He only saw that the stone walls of dozens of meters near the Earth Fire Lake were all red, and the temperature was obviously extremely high.

What surprised Yang Dong even more was that at a distance of tens of meters from the edge of the Earth Fire Lake, there were hundreds, thousands of irregular holes, each of which was tens of meters high, and near the cave entrance, there was a huge monster dozens of meters long, with red skin all over its body, and the monster had a flat and often huge mouth, which was a bit similar to the crocodile mouth in the previous life.

Yang Dong swallowed his saliva, and turned his head to look at Xia Houjie beside him in shock.

Xia Houjie also looked shocked, and reached out and gently pulled Yang Dong.

The two quietly returned to the cave.

"Master, what's going on?"

Xia Houjie was extremely excited, and said tremblingly:

"Yang Dong, I ,,, we ,,, probably ,,, found the legendary ,,, Source of Earth Fire!"

"The source of the fire, what is that?"

Xia Houjie took a deep breath and pulled Yang Dong to walk more than ten meters away from the cave again, making sure that speaking here would not alarm the monsters around the Earth Fire Lake outside, and said.

"Yang Dong, it's dangerous here, we have to leave immediately. ”

"Well, why, you haven't told me what the source of earth fire is?"8
