"I am from the Earth and Fire Twin Spirit Root, I was once plotted by someone and poisoned, and after detoxification, the Fire Spirit Root shrank, and the realm also fell." Speaking of this, Xia Jianfeng was saddened.

"That's it! I really didn't see it, what kind of poison was so powerful that it made the fire spirit root shrink? ”

"A kind of cold poison, now I only practice the earth spirit root, the higher the cultivation, the more the fire spirit root shrinks, I want to re-cultivate the fire spirit root, I want to learn the refining weapon." Xia Jianfeng said with a serious expression.

Lei Xinyue listened to Xia Jianfeng's words, nodded, and was noncommittal.

As the passage went deeper, the fire crystals on the cave wall became more and more obvious, more and more, and the temperature inside was also higher, and the rolling heat wave was coming, Lei Xinyue could still withstand it, but Xia Jianfeng was sweating profusely, and his skin was red, Lei Xinyue hurriedly turned on the protection of the flying boat, and the temperature plummeted instantly, making both of them a lot more comfortable.

Lei Xinyue was even more curious, what was going on underground, so hot.

All the way deeper, there were no lizard guards for a long time, but there were more and more fire crystals on the cave walls, and in the end, the cave walls were full of fire crystals, and the fire aura was even more refined.

Xia Jianfeng saw that his saliva was about to flow out, Lei Xinyue held back the excitement in his heart, went deeper, and finally came to the end, where it seemed to be a vast fire crystal underground palace, all of which were fiery red spars, including the ground, there was a white jade platform in the center of the underground palace, and there was a cluster of blue and faint flames on it, only the size of a soybean, but it had the power of burning the sky, all the high temperature and scorching heat were because of this small flame, maybe the fire crystal veins here were produced because of this small flame.

Lei Xinyue's heart is hot, according to the situation here, this is undoubtedly a different fire from heaven and earth, it must be collected, grandpa and Lei Ming are both fire spirit roots, if they can collect it for their own use, even if it is a trace, they can also cross the seas.

Lei Xinyue approached slowly, although she had been in retreat for fifteen years, and she had made up a lot of knowledge, but how to collect different fires, she wouldn't, and there was no container that could collect different fires, Lei Xinyue took out the transmitter and played the magic trick, and the image of Qingyunzi jumped out.

"I've seen the master."

"What?" Qingyunzi was concise and to the point.

"The apprentice found a cluster of strange fire in the center of the earth, and I don't know how to collect it, please ask the master for guidance."

Qingyunzi's phantom turned around and said, "It's the innate fire, Nanming is away from the fire, but it's not very pure." As he spoke, he waved his hands, and a jade box flew out, and the blue and faint flames were collected into the jade box, and then the jade box gently fell into Lei Xinyue's hand.

Lei Xinyue said happily in her heart, "Thank you, Master." After a pause, he said, "Oh yes, Master, can this person's fire spirit root still be cultivated?" ”

Qing Yunzi glanced at Xia Jianfeng with contempt and said, "It's okay for him to eat your dragon fruit." ”

"Oh! Thank you, Master, for your advice. ”

Qingyunzi looked at Lei Xinyue a little playfully and said, "If you don't move quickly, I'm afraid you'll have to explain here." ”

Lei Xinyue was about to ask why, but Qingyunzi's figure disappeared.

"Oh no, as soon as this fire disappears, the temperature of the entire cave has dropped, and those lizards will definitely find the abnormality and come in to check." Xia Jianfeng immediately thought of the problem.

Lei Xinyue looked at the fire crystal of the entire underground palace, and was reluctant to leave immediately, gritted his teeth, enlarged the flying boat, and used the flying boat to hit the cave wall hard, and a large piece of fire crystal fell off as soon as it hit, Lei Xinyue controlled the flying boat, desperately rammed, rushed left and right, and collected the fire crystal while colliding, and did not forget to put away the jade platform, even Nanming could not be burned by the fire, it must be precious.

This flying machine was given by Qingfeng, it is considered a demigod weapon, and it was actually used by Lei Xinyue to hit the fire crystal, and I am afraid that there are few people who use the flying machine in this way. ╭╮

Xia Jianfeng was speechless for Lei Xinyue's simplicity.

At this time, the lizard outside felt the ground shake, and the scorching temperature of the past was gone, and the monitor lizard hurriedly climbed into the depths of the passage as fast as possible.

Lei Xinyue felt a strong aura approaching, hurriedly put away the fire crystal, shrunk the aircraft again and hid it, and then flew towards the exit quickly, the monitor lizard was anxious, and did not find that Lei Xinyue's flying machine passed by it.
