It was surprisingly cold under the crater, which greatly surprised the two of them. There are many karst caves below, all of which are left by the eruptions of the volcano, and some of them may lead to the underground O fire veins.

"What now?" asked the old demon Xu as he looked at the two large passages below.

"Let's go our separate ways, whether we find anything or not, and meet here in three days. Wei Wuxian said.

"Okay, that's it, I'll go over there and have a look. ”

Wei Wuxian's proposal was exactly what the old demon Xu wanted, and he also wanted to get the treasures here before Wei Wuxian.

The two of them acted separately, and after entering the passage on the right, Wei Wuxian released Yan Que Bao, this guy has an extremely strong ability to sense fire-type things.

The passage has been diagonally downward, and I don't know how many forks have been born during this period, if it weren't for Yanque Ah Bao to lead the way, Wei Wuxian would really have a black eye and didn't know where to start.

The further down he went, the more pressure grew, and there seemed to be a bright light in front of him when he was about to dive below a thousand zhang, which made Wei Wuxian excited, and continued to move forward, coming to a crystal cave.

The cave was large, and the ground and surroundings were full of crystals, mostly colorless crystals, but there were also other colored crystals mixed in, shining in the red light emitted by the Flame Sparrow Po.

Wei Wuxian's divine sense swept around, but he didn't find anything special, these crystals were just ordinary crystals. Looking at Flame Sparrow Po, this guy is now spinning around a huge crystal pillar that has fallen upside down.

"Is there something weird there?"

He walked over and used his eyes to examine carefully, but he still found nothing, it was just an ordinary crystal pillar.

Suddenly, Bao flew to another crystal pillar and pecked with his beak, as if to peck something out of it.

Wei Wuxian swept away with his divine eyes again, his divine eyes could now see the essence of things, and no illusion could hide in front of him.

But the result is still the same!

This made him a little confused, and the message that Flame Bird Po had passed on to him was that there was a guy hiding in the cave who was spying on them all the time.

Wei Wuxian felt a little creepy, with his cultivation and supernatural powers, he couldn't find the face of the voyeur, wouldn't it be very dangerous if the other party had evil intentions.

Flame Sparrow Po suddenly stopped his movements and flew to his shoulder.

"That's gone!"

Wei Wuxian was silent, no wonder Guo Shengshou came here several times and failed to get his hands on it, that thing was really extraordinary.

He was about to retreat when he heard the voice of the Spark Boy in his ears.

"Master, the little one knows where that thing came from!"

Wei Wuxian asked with joy in his heart, "What is that?"

"The little one doesn't want to say. ”

Wei Wuxian wondered, "Why?"

"The little one is afraid that the old man will forget the old love if he has a new love!"

Wei Wuxian was even more puzzled: "What new love and old love?"

"Master has Bai Ling'er, and now he doesn't care much about me, if there is another one, won't I even have a place to stand!" Xinghuo said aggrievedly.

Wei Wuxian said in his heart, where is this, but with a smile on his face, he said with relief: "How come, the master loves Xinghuo the most, Xinghuo is the first fire spirit that the master receives, no matter how many come, they are all your younger brothers." ”

The Spark Boy said cheerfully, "Really, sir. Then I can discipline them for the master in the future?"

Wei Wuxian nodded and said, "Of course, you are a senior brother!"

He finally understood this guy's intentions, but it was good to have someone in charge, so as not to panic with the twitter.

Bai Ling'er said: "Then I'm the second senior brother." ”

It will always remember how the Starfire Boy bullied it at the beginning, and it has nothing to do with Starfire, but it seems that it is not bad to have the opportunity to abuse the new junior brother.

Wei Wuxian was sure: "Of course. ”

Bai Ling'er said happily: "I also say what that guy is!"

The Spark Boy coughed on the side and reminded, "I'm a senior brother!"

Wei Wuxian thought that the feelings were clear to him, but he didn't understand.

"Starfire, what the hell is that?"

"Like us, it is also a kind of spiritual fire generated between heaven and earth, because it is born from the crystal of the purest underground abyss, it is called 'Phaseless Crystal Flame'!"

"Phaseless Crystal Flame!"

"Yes, it is formless, as long as it doesn't reveal its firepower, even the Great Luo Immortals can't peek through its hideouts. ”

"But how do you know it's it?"

"We all have a psychic connection between the spiritual fires, and although we know that it is here, we can't determine its exact location. ”

"So how do you catch it?" Wei Wuxian asked the question he was most interested in.

"In this world, there is nothing to restrain it, but those masters don't have it. ”

"Aren't you entertaining me, master!" Wei Wuxian's teeth itched a little.

"How dare the little one, but there is something on the master that can subdue it. The Spark Boy said hurriedly.

"Oh, what's that?"

"Did you forget the 'Qiankun Mirror'?"

Wei Wuxian's eyes lit up, why did he forget about it.

The Qiankun Mirror can reverse yin and yang, and although his cultivation cannot fully exert its power, it should be no problem to only target a fire spirit.

The next thing to do is to wait, as soon as the phaseless crystal flame appears, you can start to do it.

Yanque Bao couldn't stay idle, and got into the passage below, which led directly to the underground fire vein, it hadn't absorbed fire for a long time, and its body was a little weak.

Wei Wuxian simply sat cross-legged on the crystal and meditated pranayama, and two and a half days passed in the blink of an eye, but the Phaseless Crystal Flame still did not appear.

Only half a day was before the time agreed with the old demon Xu, Wei Wuxian got up from the ground, ate and drank enough, and the fat Yanque Ah Bao woke up from his sleep, shook his little head twice, yawned, and then flapped his wings and flew back to Wei Wuxian's shoulder.

Wei Wuxian walked around the cave, wondering if he should go out first when the Yanque Ah Bao on his shoulder suddenly screamed excitedly.

"Master, that guy is here!" reminded the Spark Boy at the same time.

Wei Wuxian was overjoyed in his heart, and when he was about to make a move, his face suddenly changed, and he stuffed Yanque Ah Bao into the spirit beast ring, and his body turned into a ray of light and hid in a passage on the side.

It didn't take long for a light to fly outside the cave, and as soon as the light faded, Guo Shengshou actually went and returned!

The guy looked around, and then laughed: "Little baby, I'm here again, look at what this is, this time you can't escape from my palm." ”

I saw an extra bead the size of a goose egg in his hand, and there was a faint red light flashing on it.

"Flame Beads!" the Spark Boy exclaimed in surprise.

Of course, its voice could only be heard by Wei Wuxian.

"What is a Fire Bead?" Wei Wuxian asked, stunned.
