Li Ming held a spar that emitted a yellow halo in his hand, which immediately made the players who had fallen into darkness see a ray of light, and also made the nearby cave clearer.

"What is this thing that still glows?" Wonderfully asked.

"It's just a spar for lighting, which can shine for a long time, and has no other use." Li Ming explained.

This spar was the last time he explored the underground palace, but Tianxinhong took out a piece from it and was directly asked to leave by Li Ming.

I didn't expect this spar, which can only be illuminated, to play a role here......

As the hedron emitted a bright yellow glow, the surrounding caves finally got some clarity.

Because the valley is already very dark, players have always thought that this mountain wall is pitch black, but under the light of crystal, the rock wall in the cave is actually gray-white rock.

And the strong smell of nitrate emanates from these rocks.

"What kind of cave is this, the stones look different." Shocking Cheng walked to the mountain wall, stretched out his hand and knocked on the rock wall, it felt very hard.

"It's not easy to set up here, you look at the ground." Fan Hua squatted down and bent down to pick up a scattered gray stone from the ground.

"No, this stone still has attributes, everyone look at it." Loneliness was beside Fan Hua, staring at the gray stone in his hand, and suddenly let out a coquettish cry.

Nitlite Fragments: Special materials for the system, rare auxiliary materials, which can be used in the auxiliary manufacture of firearms.

Warning, this material is very dangerous, do not come into contact with fire!

……

What the!

Everyone looked at the ground and picked up a piece of gravel, and there was a systematic introduction to the attributes, and the content of the introduction was even more incredible!

"Is this a special material, or a rare auxiliary material!" Jing Lan said excitedly.

"It's a good thing, and I don't know exactly what it's used for, but I dare say that this material will definitely be a treasure in the future!" Shocking City couldn't help but say in surprise.

"It's the first time I've heard of firearms-assisted manufacturing." Fan Hua said with a smile.

"Looking at the system warning, if you light the torch just now, I guess we will all be unlucky." Loneliness like smoke smiled.

"This material is very dangerous, do not come into contact with fire? What happens if I come into contact with a source of fire? Fan Hua asked puzzled.

"It's easy to find out, we can try it now." Li Ming also stretched out his hand curiously, took the fist-sized gray stone from Fan Hua's hand, turned around and walked towards the entrance of the cave.

A group of people followed him, curiously appearing at the entrance of the cave, and there were countless monsters densely packed outside.

Li Ming exhaled the package, took out a torch, rushed forward a few meters, and immediately chose to use the torch when the monster group had not yet besieged him, and the raging fire suddenly burned, but the cave where he had been far away was not in danger.

I saw him wave his hand, and the stone in his hand passed through the torch......

Rumble!

A huge ball of fire appeared in an instant, and the fragments of the fire saltstone suddenly burned violently, flying directly over the torches and falling into the group of monsters, a huge ball of fire exploded and dispersed, and a fire damage number burst out on the top of the heads of the surrounding monsters!

"I'm dizzy, so fierce!" Fan Hua was so frightened that he looked straight in his eyes, if he had lit the torch just now, the fire and nitrate rock in the entire cave would burn and explode, and the whole team of players would probably be incomplete!

"Oh my God, this is too scary...... " exclaimed Shock.

"What a powerful saltpeter!" Li Ming was also frightened by the situation in front of him, and hurriedly threw the torch back into the parcel space......

"Isn't it all this kind of stone in this cave?" Avril asked worriedly.

"I wish it was all saltpeter, it's a huge vein!" Shocking City laughed.

"Let's go, everyone should be careful and safe now, it's best to keep an eye on your weapons, as long as you accidentally rub out a little spark, we will all hang up!" Li Ming warned.

"Oh my God!" The teammates were so frightened that they quickly put away their weapons.

Li Ming held the crystal to illuminate the wide cave in front of him, and continued to walk all the way.

The teammates followed, nervously monitoring the surroundings, and found that the entire cave wall was almost entirely fire nitelite, which made them more careful, lest they walk and kick a rock to rub out sparks.

After walking through the cave dozens of meters long, the front became darker and darker, and even the crystal light could not illuminate the space too far away.

But at the forefront, the cave came to an end, and a huge cave was revealed, which looked particularly eerie.

Swish!

At this moment, on Li Ming's finger holding the crystal, a faint black light shone, which made him suddenly surprised.

The Obsidian Ring has reacted!

This shows that in the cave ahead, it has begun to approach the location of the demon cave, and this is really the setting of the demon cave!

Finally found one, but the reclusive priest warned that the demon cave was very dangerous, and the demon cave near the imperial city was stronger than that of Huangsha Town!

This is not to say that the strength of the Spider Queen is weak, it is just that the system adjusts the strength and weakness of the players according to the strengths and weaknesses of the players.

"What was that flash?" Lonely as smoke asked curiously.

"It's the ring that detects the magic cave that flashes, which means that there is indeed a demon cave here, from now on, everyone should be extra careful." Li Ming frowned and said.

"Ah, I've really found the Devil's Cave!" One by one, everyone became more nervous.

However, since entering the cave, they have not seen a single monster, which means that danger must be ahead!

Cautiously walking to the end of the cave, Li Ming finally understood a little bit of the terrain setting here through the illumination of the crystal light.

The five openings under the cliff were actually connected together, and whoever came in from them would come to this cave, for he had already seen that four or five forks had appeared nearby, all of which were connected to one side of the cave.

In the cave ahead, after the yellow light shone, the ground was already a pitch-black rock, no longer the appearance of saltpeter.

The teammates came to Li Ming's side together, and they had already noticed this situation, on the stone wall on the side of the cave, the color had darkened significantly, and they reached out and touched the stone wall, and then tried to check the system properties, and found that the stone wall here was already an ordinary rock.

"Alright, the danger is over, and we can use the torches." Fan Hua let out a sigh of relief.

"You'd better be careful and check it out." Avril said nervously.

"Attention, the danger of firepeter may be lifted, but we will encounter an attack by monsters at any time, everyone pay attention to the movement around us, and bring the kelp forward." Li Ming said.

"Okay." Caribbean kelp strode to the front of the group.

Li Ming handed the crystal to him to lead the way, and hid behind his back......

Because he knew very well in his heart that the closer he got to the Demon Cave, it meant that the monsters in the Demon Cave were getting closer and closer!

As the Caribbean Kelp entered the cave first, their teammates formed a defensive formation and followed, and soon they were far away from the fire cave and came to a pitch-black cave.

After entering the cave, the ground is full of uneven pits, and every step you take, you either step into the small pit or stand on the hill, and your body is also high and low.

When they entered the cave, it was only a dozen meters, and in the silent cave, there was already a faint whistling wind, and several looming black shadows appeared in the distance around them one after another......
