"I also find it very strange." Ruotao was confused when he heard Gu Sangnu's question, and then thought about it again. Suddenly, she said, "Do you still remember? I just kicked this guy, and its body rolled near the entrance of the cave, and then the light shone..."

"Yes, then the magic stone monster disappeared!" As soon as she reminded her, Gu Sangnv's mind flashed and then said, "Can this guy's invisible ability be used in this cave?"

Ruotao smiled and said, "Hehe, don't say it, there is really a possibility. Otherwise, let's try it now?"

Gu Sang asked: "How to try?"

"Of course I took this guy into the cave and saw what was going to happen."

Ruotao said: "It will be beneficial for us to do this, otherwise we will encounter other magic stone monsters later. Who can guarantee that these guys have entered an invisible state? Wouldn't it be very troublesome to be attacked by them?"

"What I mean is that you must figure out how the magic stone monster is invisible." Gu Sang Nu nodded, and at the same time, Ruotao said: "Da Touwei, you carry this guy and let's go into the cave."

"Aowu!" Hearing this, Shanwei, four armed arms, agreed, grabbed the demon stone monster like a dead dog, and followed the two girls forward.

"Swish swish swish swish!" As soon as they entered the hole, they heard a harsh sound again. At the same time, a strange light appeared, which happened to fall on the surface of the magic stone monster in the hands of Si'an Shanwei.

"Look, this guy is going to disappear again!"

Ruotao saw the body of the magic stone monster gradually fading, and immediately shouted. Gusangnu had an idea and immediately used the wooden magic wand to create several spiritual roots and quickly knitted them, like an umbrella cover, blocking the magic stone monster's head. In an instant, the guy's body became "clear" again.

"Look, as long as you block that light, the magic stone monster will not disappear!" Hearing the words of Gu Sangnu, Ruotao's eyes lit up and she shouted in surprise: "It's true, you are quite smart, you actually discovered this."

"Actually, I was also thinking a lot, but I didn't expect that I was really confused." Gu Sangnu said: "What we have to do now is to find the source of light quickly. In this way, we can destroy the invisibility of all the magic stone monsters!"

"Okay." Hearing her words, Ruotao also began to pay attention to the surrounding environment. She also said, "Da Touwei, Ghost King, you bring the demon brothers to release some fire spirit. In this way, you can illuminate the nearby area and find the source of that weird light."

"Aoao." Hearing this, Shanwei, the Ghost King and the demons agreed in unison, and then immediately burst out with dazzling fire spirit. "Swish!" In an instant, there were already a lot of light around.

"Woooooooooooooooooo!" Suddenly, a demon who flew the highest in the sky made a cry. Ruotao and Gu Sangnu looked up and found that the other party discovered something strange in the cracks in the rocks on the top of the wall, so they immediately opened their mouths to warn.

Gusangniao said: "There seems to be something shining in the cracks of the rock. Could it be the source of light that makes the magic stone monster invisible?"

"It's possible." Ruotao nodded, then said loudly: "Hey, break down a piece of the shining stone and take it over for us to see."

"Bang!" Hearing this, the demon clenched his claws into a fist and hit the rock on the top of the wall. Suddenly, a piece of gravel fell with the wind, and was caught by Ruotao.

"Hey, there are a lot of flashing beads signed in this stone. Could this be..."

"Yes or no, let's try it, it's here."

As he said that, the ancient Sangniao took the stone piece with shiny beads and shook it in front of the magic stone monster that was about to die. "Huh Huh Huh!" In an instant, the other party's body shone again, and the shiny beads reflected each other, and the magic stone monster disappeared from the spot again.

But at this time, Ruotao and Gu Sangnu knew that this guy hadn't moved at all.

"Huh...b!" He threw the stone piece on the ground more than meter away, cutting off the light source between it and the magic stone monster, and the other party's invisibility state immediately became invalid.

"It's true that's not what I expected." Ruotao said: "It seems that the magic stone monsters will be invisible, and they are limited to this cave because of the shiny beads in the stone slab of the top of the wall. As long as there is no light from the beads, they cannot enter the invisible state at all."

"Well, we have all understood the details, but why is this guy invisible? To be honest, it's really a bit puzzling."

Hearing Gu Sang Nu's words, Ruotao thought for a while and then said, "It may also be related to the magic stone monster's residence here. Forget it, don't think too much. If you think too much, your head hurts. Let's do your own business quickly. It is important to find out the whereabouts of the beast's bones and fire."

"Yes, go into the cave. This time, there is no need to worry about the 'invisibility method' of the demon stone monster." Gu Sangnu smiled while walking forward: "Maybe we can use our tricks and play with these guys."

"Is that so? Tell me quickly, what are your good ideas." Then, Gu Sangnu leaned into Ruo Tao's ear and muttered for a while, and heard her nodding repeatedly: "Yeah, this method is good, so let's do it like this."

...

After a while, everyone had already arrived in the depths of the cave.

In fact, along the way, Gusangnu and Ruotao had discovered many demon stone monsters in an invisible state. Although these guys were hiding in the dark, no one rushed out to attack the two girls rashly. Maybe they were worried or someone issued an order not to act rashly.

"Hey, these magic stone monsters are unwilling to take the initiative to attack. It's so strange."

"That's right, I'm a little anxious when I waited." The two girls whispered, and then Ruotao whispered: "Otherwise, let's be a rush to alert the snakes and make them nervous and panic themselves. In this way, maybe there will be a guy who can't hold back and wants to do it."

"Yes, just do that." Gu Sang Nu nodded, thinking that this was a good idea. Then, Ruotao winked at a demon beside her and signaled that the other party could take action.

"Woooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooo

It was a while, and then the demon ghost suddenly roared, then rose into the air and flew towards the area in front of the left. "Huh--" The next moment, the demon ghost opened his mouth and squirted out a large amount of blazing and scorching power of original fire, burning a stone in front of him kept crackling.

In fact, there were two demon stone monsters that entered the invisible state on the side of the stone. They were very calm at first and thought that the demon had not discovered them, but who expected that the other party suddenly spit out flames to burn the rocks, and even they were tortured, and their bodies were trembling with scorching heat.
