Although the entrance of the cave is small, it is much larger after entering, and there is no problem with the two of them, the cave wall is a solid rock, and the color of the rock is very dark, and the smell of fire is slightly revealed, and the cave wall is smooth, as if it has been worn by someone.

A wave of heat came in, and the temperature inside was significantly higher than outside.

Lin Wan'er was a girl after all, she followed closely behind Lin Xiao, her expression was very nervous, and now that she was seriously injured, she was really a little scared.

The cave gradually widened, and there was no end in sight, but the rocks on the walls of the cave turned dark red and the temperature became higher and higher.

"Fire Rock!"

Lin Wan'er looked at the dark red rock on the stone wall and exclaimed, no wonder the temperature in this cave is high, it turns out that this is a igneous stone mine.

"Fire rocks?"

Lin Xiao was slightly stunned, although he had a lot of knowledge in his memory, most of it was obtained from the Lin family, and the things recorded in the Lin family's books were also relatively one-sided, so there were many things that Lin Xiao was not familiar with, for example, this fire stone was the first time he had heard of it.

"That's right, no wonder the temperature here is so high, this igneous rock was formed by the eruption of an underground volcano, and the temperature below it must be even higher. ”

Lin Wan'er has been in the Snow Heaven Sect for nearly ten years, and she has seen a lot of knowledge, and she can see it at a glance.

"Isn't that an extinct volcano erupting from the ground?"

Lin Xiao groaned, with the knowledge of his previous life, it was like this, but he didn't say it, because people probably couldn't understand it.

"Lin Xiao, I am practicing the Ice and Snow Technique of the Snow Heaven Sect, this place is not suitable for me to heal, I can't continue to move forward. ”

Lin Wan'er's face was slightly red, her breathing was a little short, and she felt a sense of suffocation, the Snow Heaven Sect cultivated special ice and snow exercises, and the most suitable place to cultivate was a cold environment.

"Oh, then you're here to heal, I'll go in and see. ”

Lin Xiao groaned, he found a relatively low temperature place for Lin Wan'er to heal, and he walked directly forward, because he felt that there seemed to be something in it.

The cave seems to have no end, and the further you go inside, the higher the temperature becomes. The color on the stone wall turned fiery red, as if it was about to burn, but Lin Xiao did not feel any discomfort, but felt very comfortable.

He felt that his body was constantly absorbing the heat, and a sense of vicissitudes arose.

"What's going on, how I feel like something is awakening inside me. ”

Lin Xiao was shocked, he had basically adapted to his body. It was the Divine Ding that was absorbing the heat wave, and the phantom of the Divine Ding was becoming more and more obvious, Lin Xiao exclaimed.

Dan Shending, this strange and familiar name, strange because he still doesn't know what this thing is for, familiar because this thing has appeared in his body since the day he remembers, and he can feel it every day.

Lin Xiao kept walking forward, and a fiery red heat wave erupted from the stone walls around him, as if he was about to burn his whole person.

Finally came to the end, Lin Xiao didn't know how long he had walked, and finally came to the end, a magma river flowed in front of him, and in the middle of the river there was a ten-square-meter rock pile, on which a dark red plant was growing, flowering and bearing fruit at a speed visible to the naked eye.

"Earth Flame Fruit!"

A name instantly appeared in Lin Xiao's memory, and he had an urge to rush forward.

The Earth Flame Fruit, which grows in the underground fire stones, is the best in the royal elixir, which can assist in cultivation, alchemy, and also contains a trace of the law of fire, it is the best elixir for the powerhouses of the Star Emperor Realm, and it bears fruit once in a thousand years, and it results three at a time, which has never appeared in the Xiwu Kingdom.

The information about the Earth Flame Fruit appeared again, but Lin Xiao found out this time, this information came from Dan Shending, as if Dan Shending was a soul, transmitting information to him.

"Grandma's, what the hell is this Dan Shending, how does it feel weird, I don't know how to take it out. ”

Lin Xiao groaned, this Dan Shending has been shrouded in his dantian and protected himself, but today Lin Xiao suddenly became a little scared, how can this thing be like a living thing, especially after seeing a good elixir, it seems that he can manipulate himself to take it over.

The rhizome of the Earth Flame Fruit is very thick, and there is a fiery red heat wave on it, and the Earth Flame Fruit also bears three pieces, which are green at first, and then grow and darken in color.

"Roar!"

A loud roar instantly sobered Lin Xiao up, the magma shook instantly, and a fiery red giant snake flew out of the magma, that's right, it flew out, Lin Xiao immediately retreated, the demon beast that can fly is at least the Star Spirit Realm, this is not something that he can deal with.

The snake's body was extremely large, its body was red, and an extremely powerful yuan force emanated. Lin Xiao saw the giant snake and knew why the stone wall that came in was so smooth, it was smoothed by this giant snake, this snake was able to survive in the magma, it can be seen that his skin is not ordinary thick.

"Flame Spirit Snake! Living in magma, an adult Flame Spirit Snake can cultivate to the peak of the Star Spirit Realm, and it is extremely ferocious. ”

The news about this snake appeared in Lin Xiao's mind again, and Lin Xiao kept retreating, but the flame spirit snake stared at him.

"Human, disturb my cultivation, die!"

The giant snake spits out words, but the words are very rough, some of them are not clear, and according to common sense, the demon beast must be in the Star King Realm to understand human speech, and this flame spirit snake can open his spiritual wisdom so early, which shows that his talent is not bad.

"Poof!"

The spirit snake roared angrily, and a ball of flame pounced directly over and enveloped Lin Xiao, and the flame just approached Lin Xiao, and was directly sucked into his body by him, and disappeared in an instant, Lin Xiao was still standing well.

"Human, you!"

The giant snake looked at Lin Xiao and was also a little shocked, Lin Xiao's cultivation could not be transformed into a star realm, and his own spiritual fire could completely burn him to ashes, and now Lin Xiao was the same as a nobody, the giant snake was a little confused, how did this human do it.

"Flame, I need flames, boy, if you want to live, let him keep spewing flames, or you will die. ”

A strange and old voice came into Lin Xiao's mind, making Lin Xiao also stunned and looked around.

"You, who are you?"

Lin Xiao asked in a low voice.

"Don't ask me who I am, this Flame Spirit Snake is a cultivator at the peak of the Star Spirit Realm, he is waiting for the Earth Flame Fruit to ripen, as long as he takes it, he can break through the cultivation, and I won't be able to save you at that time." ”

The old voice urged, Lin Xiao thought for a moment, and finally walked towards the Flame Spirit Snake.

"Why is the temperature of your flame so low, isn't there an even higher temperature? ”

Lin Xiao asked with a sneer.

"Boy, you've me off!

The spirit snake was furious, and clusters of flames erupted, and someone seemed to be cheering in Lin Xiao's body.
