In the space on the other side of the wall, cyan flame people held red flames and walked towards the center of the underground space. In each flame, a crimson thing loomed into the eye.

In the center of the underground space is a platform one meter above the ground, with an area of more than ten square meters, and there are grooves all over it. The cyan flame man walked over to the stone platform and lowered the flame in his hand into the groove of the platform.

The gap in the wall was too small for Li Fei to see what was inside the groove.

"What the hell are these guys doing?" Li Fei's heart was full of curiosity.

Before he figured out the situation, he was patient and continued to observe secretly.

For several hours, the Flame Man was busy putting the flame on the central stone platform, and did nothing else. Li Fei lay behind the crack in the wall and was about to fall asleep.

"It's boring."

Li Fei wanted to go offline, but in order to satisfy his curiosity, he still waited.

After another moment, an old man in a white robe walked into the underground space. The white-robed old man was holding a magic staff with a serious face, and the cyan flame people nearby saw him and hurriedly avoided him.

Li Fei hurriedly cheered up and carefully looked at the white-robed old man to see what he was going to do.

The white-robed old man paced back and forth in the underground space, arranging for the cyan flame man to do things. After finishing the order, he walked to the side of the central stone platform and looked at the stone platform in front of him with a solemn expression.

"Whether the Vulcan Banner can be repaired or not depends on today." The voice of the white-robed old man was not very loud, and Li Fei could just hear it.

What is the Vulcan Banner? Li Fei said secretly in his heart.

At this time, the white-robed old man raised his staff and pointed towards the stone platform in front of him, and the stone platform was suddenly full of glory. The many cyan flame people next to them walked to the stone platform, turned into a cyan flame, and merged into the stone platform.

Rumble!

There was a muffled sound at the bottom of the central stone platform, and the central stone platform began to rotate, and the stone walls around the underground space gradually disappeared.

The stone wall in front of Li Fei also began to disappear.

mmp！

Li Fei scolded in his heart, very anxious, if the stone wall disappeared, he would definitely be exposed.

The white-robed old man sat cross-legged on the ground, his staff on his knees, closed his eyes, and slowly floated his body above the central stone platform.

The fragments of the Vulcan Banner in the groove of the stone platform all floated up and swirled around his body, ready to repair the Vulcan Banner.

The surrounding stone walls all disappeared, and Li Fei was completely exposed in front of the white-robed old man.

However, the white-robed old man would not have thought that someone would come in here, he was now in a state of concentration, like an old monk in a state of concentration, so he didn't notice Li Fei in the corner.

"This old man didn't see me?!" Li Fei said in surprise.

At the same time, above the desert.

All the flames in the Heavenly Fire Pit converged towards this underground space, and the surging flame power poured into it crazily, turning the underground space into a sea of fire in an instant.

The Fire Serpent King saw that all the flame people near the Heavenly Fire Pit had disappeared, and the fire in the Heavenly Fire Pit had also disappeared, and the ambient temperature had plummeted.

Li Fei was in the midst of a sea of fire, and the flames scorched his body violently, causing him to keep bleeding.

-560

-560

-560

……

If Satsuki's moonlight skill hadn't helped him regain his health, he would have taken more than three thousand damage per second.

Li Fei's maximum blood volume of 280,000 can support more than eight minutes in the sea of fire. The biggest question now is whether to leave or not, the Escape Technique skill has cooled down, and he can leave here.

If he left like this, Li Fei was a little unwilling.

Wait!

Li Fei lay still in place, looking at the white-robed old man floating in the air in front of him.

The red sacrificial refining circle appeared under the white-robed old man, the power of the fire attribute was suffocating, and the surrounding flames were centered on the stone platform, forming a flame vortex.

The fragments of the Vulcan Banner swirled in the flame vortex, and a black iron rod more than a meter long rose from the small hole in the center of the stone platform. This black iron pole is the flagpole of the Vulcan Banner.

The fragments of the Vulcan Banner moved closer to the iron rod, and kept splicing together to form a flag.

Five minutes later, the Vulcan Banner gradually took shape in the sacrificial refining formation, and the remaining fragments were still moving towards the Vulcan Banner. The Vulcan Banner consists of a black flagpole and a rectangular flag with a flame pattern emitting a red glow.

Li Fei used the eye of science and technology to investigate the attributes of this equipment.

Name: Vulcan Banner

Attribute:???

The level of the Eye of Technology is too low to detect the attributes of this equipment, but it is certain that this equipment is definitely very good

The amount of blood in Li Fei's blood bar is getting less and less, and he will be burned to death if he doesn't leave.

Do you just leave it?

Li Fei didn't get any benefits, and he was unwilling. Just when Li Fei hesitated, the white-robed old man above the stone platform shook his body slightly for some reason.

With this sway, the sacrificial refining circle under his body was slightly affected, and a layer of shallow ripples was opened, and the nearby flame vortex also made a trace of waves.

Most of the fragments of the Vulcan Banner in the Flame Vortex were still close to the middle, but a small piece was thrown out.

This small fragment was only the size of a thumb, flew out of the flame vortex, flew straight towards Li Fei, and smashed into Li Fei's face.

"And this kind of operation?"

Li Fei took off the small rag on his face with his claws and put it in the palm of his hand. This triangular piece of red cloth is part of the Vulcan Banner.

"This wave is not a loss, open and slip."

Li Fei took the red rag and released the Escape Technique skill to escape from this underground space.

As long as it is refined, the Vulcan Banner will become perfect. The white-robed old man would never have thought that a piece of cloth in the Vulcan Banner would be picked up by Li Fei, and in this case, a corner of the Vulcan Banner would be missing.

Li Fei sneaked underground, flew to the surface of the desert, and soon came to the surface of the desert.

He turned his head to look at the Heavenly Fire Pit, where there were no flames left, and all the flames had been sucked into the underground space.

"What the hell is this Vulcan Banner?" Li Fei took the fragment of the Vulcan Banner and looked at it, but he couldn't understand it, and asked Yuwen Shengtian when he went back.

The fiery snake not far away saw Li Fei come out and crawled towards Li Fei.

"Little Tiger, what did you do? How did the fire in the heavenly fire pit go out? The Fire Serpent King asked Li Fei.

Just now Li Fei said that he was going to take a look in the Tianhuo pit, and in less than a day, the flames in the Tianhuo pit were extinguished. The Fire Serpent King guessed that this matter was likely to be related to Li Fei.

"I don't know." Li Fei said, "Also, don't call me Little Tiger, call me Brother Tiger or Boss." ”

"Brother Tiger, what's going on in the Heavenly Fire Pit?" A fiery snake asked Li Fei.

"I don't know."

Li Fei himself was still a little confused, and he couldn't explain it to the Fire Snake.

"I'll take you to Demon Yuan City now."

Li Fei took out the beast bag, put the fire snake and a dozen of its mini-bosses into it, put the beast bag around his neck, and went to join Xiao Yue and them.
