"I know," Yan Ci smiled, "I didn't say it must be quicksand, or maybe something else?" ”

After speaking, without waiting for Yan Zidong to speak, he took a breath and tensed his muscles, slammed a boulder next to him, and smashed it towards this small piece of stone wall.

"Bang!"

When it was smashed down for the first time, after a loud bang, the stalactites on the surface of this small piece of stone wall began to break and collapse, and Hulala broke a piece of rubble.

Yan Ci took another deep breath, went over and grabbed the boulder, and smashed it again.

This was followed by another smash.

"Bang-"

With the third smash, a sound like an air cannon sounded, Yan Ci reacted extremely quickly, and suddenly threw Yan Zidong aside.

"Whew-"

A large hole was smashed out under the stone wall over there, and there was a smoke of fire and a strong sulfur-like smell, which soon filled the stone cave here.

"Ahem!"

Yan Ci and Yan Zidong were choked by the smoke, and the two of them coughed while waving their hands and fanning the hot smoke in front of them.

"Ahem...... What's going on? ”

Yan Zidong's eyes were a little red from choking, and he looked at Yan Ci in surprise.

Yan Ci had already calmed down, and went around to avoid the smoke coming out of the sneer, and carefully looked at it along the edge of the stone wall, "It's the lava of the ground." ”

Yan Zidong was taken aback.

However, the terrain here is complex and changeable, and he doesn't know how deep this cave is, he thought that there might be a dark river in it, but he didn't expect that it would be lava.

"It's not surprising,"

Yan Ci pointed to the stone wall and said, "Look at this side, it is different from the bottom of the well over there, it is very similar to the characteristics of volcanic rock, and it is not abrupt to have lava." ”

"But it's useless,"

Yan Zidong didn't care about exploring any geology, looked at the situation in the cave, and was immediately disappointed, "It's useless, there's no way to go inside-"

What is the use of escaping from one hole to another?

There is no way to stop the pervasive tide of poisonous insects.

Yan Ci didn't panic, and when the fire and smoke inside were almost flushed and he could see more clearly, his gaze quickly swept inch by inch in the hole.

The place inside is not small, except for one place where the lava is slowly tumbling, and the speed is very gentle, not the terrible state of a volcanic eruption.

The deeper part of the cave, which is black, can be seen in the light of the lava, and it also looks like a steep stone wall, and there is no way out.

A short distance from the entrance of the cave was a pillar of rock in a delicate position, right on top of a rock that was almost overhanging......

Yan Ci's eyes flashed.

Just lure those poisonous insects into this hole, and then quickly break the rock pillar after the poisonous insects crawl in...... The entrance of this fire hole must collapse!

In this way, those poisonous insects will be blocked in this fire hole!

But there's a problem right now.

How do you bring those poisonous insects in?!

"Rustle—"

At this time, in this cave, countless poisonous insects were surging closer, and dense poisonous insects were surging over little by little, as if they wanted to drown everything here.

What to do?

"Forget it!"

Yan Zidong also saw it at this time, and threw aside the stone that he had been clutching in his hand.

The stone was stained with his blood, and it hit the black stone that the monster had thrown on the ground earlier, and a trace of black mist rose from the ground.

This trace of black mist is very rare, and it only arouses the excitement of some poisonous insects, if you don't pay attention, you really won't notice it in the surging insect tide.

But Yan Ci was so keen, his eyes suddenly jumped.
