The fire cave was not far away, and after walking for less than a day, Chen Mo had already felt the heat in the air, and the ice and snow under his feet had disappeared without a trace, revealing a large area of dry and cracked loess.

Turning around a withered yellow pine forest, Chen Mo smelled a few traces of pungent sulfur in his nose, and after moving forward for hundreds of zhang, the scenery in front of him changed.

In the distance, there is a continuous mountain, not a single grass grows, the wasteland is dry, and the flames that are constantly spewing out to the sky behind it are burning thick clouds and scorching fire.

Chen Mo stared at this scene, knowing that he had finally arrived at the fire cave. He wiped the fine sweat from the tip of his nose, hurried slowly, and spent a meal before going up the mountain.

I saw that this extremely high mountain seemed to be smashed by something outside the sky, and the top of the mountain was concave into a huge basin, and the surrounding cliffs were not smooth, but there were many natural paths, hovering up and down the cliffs, like ripples, like the water surface stirred up by stones.

Deep in the basin are dense holes, from which blazing flames erupt from time to time, burning the surrounding rocks red. Even Chen Mo, who hadn't approached yet, had already noticed a burst of fire coming from the ground.

If a mortal came here, the smoke and the smell of sulfur in the air alone would not be able to stay long.

The sun is shining on the horizon, and it will soon be night, and everyone who comes here knows that the fire wave in the fire cave only breaks out at the same time, and after nightfall, the fire will be slightly weaker than during the day, which is a good opportunity to enter.

Chen Mo covered his mouth and nose with a strip of cloth, activated the spiritual power defense in his body, and observed the thousands of fire caves in situ, the fire caves were no longer as restless as when he first came, and even the blazing temperature outside seemed to be a little cooler.

He observed for a long time, and found that the rocks near the entrance of one of the fire caves were more red than the others, and presumably there should be a fire rough stone in it.

With his mind already decided, Chen Mo got up and straightened the bamboo basket directly behind him, and walked towards the fire cave.

The distance between the entrance of the cave was only a hundred zhang, and Chen Mo quickly came to the front. As soon as he wanted to enter the entrance of the cave, he found several figures walking out from everywhere, most of them were disciples who were also carrying bamboo baskets, and the closest to Chen Mo was a woman, dressed in white, not stained with any dust.

"It's her again?" Chen Mo was quite surprised, he didn't expect to meet him here again, and subconsciously took a few more looks.

The woman also saw Chen Mo, her eyes paused slightly, and then she moved away, without paying much attention, and entered a fire cave alone, and disappeared.

Retracting his gaze, Chen Mo no longer lingered, and also plunged into the fire cave, only to find that the space in this fire cave was extremely large.

Looking around, the ground is full of red stones, but these stones are still too light in color, until they are dark red and have flashing lights, they can be regarded as fire stones.

After taking two breaths, Chen Mo frowned slightly, and found that the air around him was extremely hot, and the hot air could not enter his lungs as soon as he breathed, which made people feel that his body was hot, as if there was a fire burning in his chest.

Chen Mo knew that this was a sign of fire poison, and in such an air, if he didn't use the frost spiritual liquid, he would definitely not be able to quarry stones in it.

He took out a vial from the cloth bag he was carrying, carefully poured a drop into his mouth, and hurriedly swallowed it, feeling a burst of coolness spreading from the inside out, and then breathing the hot air in the cave, it would be fine.

The frost spirit liquid could not be wasted, Chen Mo did not dare to delay, and immediately went deep into the cave and began to search for the fire primordial stone.

About two hours later, Chen Mo finally saw a dark red in the red stone deep inside the cave.

Immediately inspected, to determine that it was a fire stone, he quickly took out the gold pattern drill, "Ding Ding" took a lot of effort, and finally took off this piece of fire stone.

This piece of fire stone is the size of a skull, and it is very heavy to start, Chen Mo estimates that it will be about thirty catties, which is already able to reach the weight that Chen Mo set for himself this trip.

However, since he had made a discovery so early, Chen Mo did not come out of the cave, but took another drop of frost spiritual liquid, searched for two more hours, and was lucky enough to find a smaller fire stone again. He took it and put it in a bamboo basket. Although the bamboo basket was a little heavy, it was not a big deal, and it was carried out of the hole.

But she didn't want to see the woman again at this time, she actually came out of the fire cave, didn't look at Chen Mo, and walked straight into the distance, and from her expression, she couldn't tell whether she got what she wanted.

Chen Mo saw that the woman's hands were empty, and he felt a little strange in his heart, after all, no matter what he sought in this fire cave, there must be a container to load. I saw a beautiful cloth bag around her waist again, and I was even more puzzled, could this cloth bag be Nazi?

Nazi is a general term for storage artifacts, whether it is a pocket, bracelet, ring, belt, etc., as long as it can store things, it is counted as Nazi.

Nazi refining is extremely difficult, so although most of its grades are not high, its value is much higher than that of ordinary spiritual weapons.

Chen Mo was envious, if he had Nazi in his hand, he wouldn't have to carry the bamboo basket so hard. But even if there is, maybe he is not willing to use Nazi to hold the fire rough stone, after all, the Nazi space is limited, how much space should there be for the Nazi that can hold the fire rough stone?

Looking at the sky, it was almost dawn. Chen Mo didn't dare to delay at the entrance of the cave any longer, so he hurriedly went away, found a place to spend the night in the dry pine forest on the periphery of the fire cave, and also laid some small mechanisms around the village to prevent wild beasts.

After all, you have to stay in this fire cave for two or three days to fill the bamboo basket, and the mechanism can also prevent the hard-found fire rough stone from being "beaten by the autumn wind".

Lying on the paved broken branches, although Chen Mo felt a little tired, he was also a little happy, the first time he entered the fire cave, he could dig out dozens of catties of fire stones, which can be said to be very smooth, which at least proves that he can use the task of the fire cave as a stable source of spirit stones in the future.

Pulling the thin line in his hand, there was a sound of bamboo tubes colliding in the distance, the mechanism worked, Chen Mo was a little relieved, coupled with the exhaustion of running around, he soon fell asleep.

But I didn't think that in the middle of the night, a sudden change occurred.

Chen Mo was sneak attacked, originally the middle-aged cultivator's cultivation was much higher than Chen Mo, plus it was a sudden sneak attack, so Chen Mo didn't even have a chance to resist, so he was restrained by the other party.

The mechanism he laid down was useless in front of this person, and he didn't give any reminder at all, and when Chen Mo reacted completely, the other party had already tied him up, and without saying a word, he sealed the spiritual power in his body and snatched his cloth bag.

Chen Mo couldn't struggle, and could only watch the middle-aged cultivator flip around in his cloth bag.

After taking out the frost spirit liquid from his cloth bag, the cultivator's face appeared with joy, and he couldn't help but speak: "This frost spirit liquid has arrived, if I can pick it today when the Blue Flame Fruit of Heaven and Earth is ripe...... The two small levels of practicing qi three into four, six into seven, are not a problem!"
