Tuanzi solemnly assured the director that he would ensure his own safety as she said.

After chattering at Feifei for a while, Tuanzi said: "Master, Tuanzi and Feifei will definitely be cautious, let's go down." ”

"Okay."

Xi Yan asked Tuanzi and Feifei to go down first, and after going down by herself, she dealt with the entrance of the cave before continuing to go deeper.

After entering the cave for a while, Xi Yan felt the heat rushing to her face. The deeper you go, the bigger the heat wave.

After walking for a quarter of an hour, the entrance to the cave was indeed much larger than Feifei said.

After careful inspection, Xi Yan felt that this cave was indeed different from before, there was no trace of excavation, and it was made naturally.

The lava armor must have sensed the difference in the ground before it made a hole to enter here.

Xi Yan is very grateful that she met the lava armor monster to have this opportunity.

"Master, it's hot here, there must be a fire." Dango's dark eyes twitched. After learning about the Flame Marrow from its master, it also understood why it was looking for the place where the Earth Fire was located.

Xi Yan said: "Well, that lava armor monster must have come to the earth fire." Be careful and search carefully after entering. ”

As soon as she entered the natural cave, Xi Yan's pace slowed down a lot. The heat wave is coming, and the temperature inside is too high.

And when venturing underground, you have to be careful. The lava armor monster was gone, and Xi Yan was very worried. Once discovered by the Lava Armor, you may lose both sides if you fight hard. And here, there must be more than one lava armor, and there are many unknown dangers waiting for you.

After about two quarters of an hour, it seemed that he had reached the end of the cave. In front of them, huge underground craters, blazing magma constantly surging, and heat waves came in waves.

Xi Yan's face was covered with sweat, it was too hot. Along the way, I was constantly washed away by the heat wave, and my body seemed to be steamed in a steamer.

Tuanzi and Feifei widened their eyes as they watched the hot magma gush up, and the fiery red slurry seemed to melt for a while. Just standing on the side, you can feel the meaning of ruin. No one can stop such ruin.

"Master, there is no way." Dango said carefully. The tumbling magma blocked the way forward, and the flame marrow that the master was looking for did not know where to look.

Looking at the situation in front of him, his rolling eyes are boundless, and it is difficult to cross the past as if he wants to climb into the sky. However, how can you be willing to give up like this.

Xi Yan said: "It's impossible to want to go over, let's search carefully to see if there is anything different here." Even if there are veins, they can't be under the magma, they must be around it. ”

One man and two pets searched along the edge of the pit.

Xi Yan looked at each one carefully, trying to find the difference.

Suddenly, I heard Tuanzi shouting: "Master, come and see here." ”

Xi Yan hurriedly rushed to the group, and saw that on the edge of the pit, on the rock wall, there was a fiery red spar, which was not ordinary at first glance.

With wide eyes and a careful look, the fiery red spar exuded a fiery aura, and Xi Yan couldn't wait to take the spar in her hand and study it immediately.

It's just that the hedron is embedded in the rock wall, and it can't be reached even if you lie on the edge of the pit.

Stretch out your arms and try a few times, but you still can't touch them. Xi Yan climbed up.

"Master, let Feifei try." Tuanzi mentions yì.

Flying to the hedron, Feifei pecked at the hedron with his sharp beak. After a while, he came to Xi Yan's side with a spar in his mouth.

Reaching out to take the spar, he immediately felt the surging firepower contained in it.

Such a small piece of hedron exudes an aura like magma. Xi Yan affirmed that this is a spar containing fire attributes, and it is also an ore.

She is no stranger to the ore Xi Yan. Before setting off, a lot of information about ores, beasts, plants, etc. has been collected. Going out on adventures, these are a must-have.

With full preparation, Xi Yan dared to go on the road.

Now that there are fire attribute ores, Xi Yan speculates that there should be other ores here.

Looking at the location of the fire red crystal, it can be seen that the formation is closely related to the magma here.

"Danzi, let's look carefully. The Flame Essence is also an ore, similar to this hedron, but different in color. This spar is fiery red, and the flame pith contains much more fire power than the spare, and its color is red and purple, tending to purple red. ”

With this piece of spar, Xi Yan and Tuanzi doubled their confidence.

Searching along the edge of the crater, I found a few more hedrons. The color is fiery red, and there are also lighter ones. But I never found a fuchsia one.

After looking for a long time, Xi Yan thought to herself, these spars are inlaid on the surface of the rock wall, which should have something to do with the continuous erosion of magma. The emergence of large veins is never so simple.

Only large veins contain a high chance of Flame Marrow. If there were large veins here, how could they be found in such a shallow place as the rock wall?

It has been studied that the formation of large veins is influenced by the leylines. And here, there is such a hot and vast magma that can form crystals on the rock wall, so there is a high possibility that veins will form deep underground.

Therefore, if you want to find the marrow of the flame, you must first find the location of the ore vein.

"Tuanzi, let Feifei look on the rock wall to find out if there are caves or anything like that." After thinking about it, Xi Yan immediately commanded. You can only go deeper if you find a cave or something like a cave on a rock wall.

Xi Yan and Tuanzi searched near the pit, while Feifei searched on the rock wall of the pothole.

At this moment, Xi Yan was very happy in her heart and let Feifei join them.

Having a pair of wings that can fly is so obvious at this moment.

After searching for a long time, just when Xi Yan was about to lose her patience, Feifei came with good news.

At the rock wall near the magma, there is a small gap. The gap is narrow, barely enough for one person to walk sideways.

When they first heard the news, Xi Yan and Tuanzi were pleasantly surprised. However, Feifei's next words made their joy dissipate suddenly.

This gap is located very close to the lava and is washed away by the lava every once in a while. And if you want to get in, you must not only avoid the lava washout, but also be able to endure the high temperature there.

The crevasse is close to the surface of the magma flow and the temperature is very high. Feifei tried several times, but he couldn't get close, let alone fly in. Just a little closer, you can feel the blazing breath coming, and there is a burning fire.

I finally got good news, but I couldn't get in.

However, everywhere I searched, there was no hole in the ground that I could go into. Only the gap that Feifei found seemed to be able to enter.

has come here, Xi Yan doesn't want to give up no matter what. You have to think of how to get in.

Xi Yan stood on the edge of the pit, looked at the tumbling magma below, and began to meditate.

Tuanzi knows the master's thoughts, and he is also at a loss.
