Xue Linglong flew up, and the Rockchip on her chest illuminated the road of the cave in front of her, Rockchip was very bright and could irradiate tens of thousands of meters, and the deep hole was almost like a bottomless pit, and even Rockchip couldn't shine to the end.

Mu Shishi followed behind Yan Mufei, and the water under her feet became more and more, getting colder and colder, and even there was a feeling of ice ballast under her feet, and the surrounding stone walls were also stained with a layer of frost.

Mu Shishi stretched out her hand and touched the stone wall, and the frost instantly stuck to her fingers, and when she pulled it out, her fingers were a little red.

"It's strange, the frost on the stone wall can instantly freeze your hands, why is the water under your feet only a little ice ballast?" Mu Shishi rubbed her frozen red fingers, very puzzled in her heart.

"The temperature of the stone wall is not the same as the stone under the feet, some stones can emit heat, and some stones can emit cold. Yan Mufei turned around and said, his big hand wrapped around the frozen red hand: "Don't touch it, be careful of the cold entering the body, the more you face the back, the colder the stone wall is." ”

Mu Shishi nodded, the stone is cold and hot, she understands this truth, but she never thought that the natural stone cave would be so clearly divided between cold and hot, this cave is really natural?

Two hours have passed, and there is still no end to the cave, and the stone wall at this time is really just like Yan Mufei said, the deeper it is, the colder the stone wall is, not to mention touching the surrounding stone wall with your hands, even if you are close, you feel like your body is going to be frozen.

Xue Linglong flapped her wings, and the more she walked forward, the more excited she became, and even the five-colored snake in Mu Shishi's illusion ring crawled out by itself, spitting out the letter as if she was very happy.

"There's a corner up ahead. Mu Shishi found the bump in front of her, and her eyes lit up.

As they spoke, the two of them had come to the corner, and it was a stone door, and on the stone door was carved a strange tree, and on the dense tree hung seven fruits, each of which protruded from the stone door.

Yan Mufei looked at the perimeter of the stone gate: "This secret gate seems to be a battle. ”

The seven fruits on the top of the trees carved by the stone gate are positioned exactly to form the position of the Big Dipper.

Mu Shishi also looked at it carefully, could it be the Big Dipper Seven Star Formation? I had seen it in books before, the Big Dipper Seven Star Formation was composed of seven people, and the people who trained the soldiers practiced the formation were synthesized in groups, and according to the number of people, the number of people who were assigned to synthesize the synthesis.

The Big Dipper above this stone gate is like a piece of paper, and the formation on the paper is dead and cannot be moved.

"Will the organ be on these seven fruits?" Mu Shishi stared at the seven fruits, if it was a battle, then this battle was not easy to start.

Yan Mufei turned his eyes to look at the dense fruit tree on the stone gate, stretched out his hand to touch the top fruit, and before his fingers could touch it, he was resisted by an invisible invisible film.

At the same time, a wave of water appeared above the stone gate, and the wave slowly opened......

Seeing this, Mu Shishi stretched out her hand to feel it, her fingers touched it softly, and she was surprised in her heart, there was indeed an invisible invisible membrane that made it impossible for their hands to get close to the stone gate.

The two of them glanced at each other, this situation was the first time they had seen it, the invisible invisible film, like cotton, was very soft, for this softness, neither the fighting spirit nor the swordsman could help it.

"It's not just that the fruit of the stone gate has ghosts, but even the outside hides invisible protection, what kind of place is this?" Mu Shishi frowned.

Yan Mufei had the same doubts, he never knew that there would be such a wonderful protective layer hidden in this continent, the stone gate of the carver, he was sure that it was a formation.

"It's cold around, and only the stones here are hot. ”

Hearing this, Mu Shishi reached out and touched the stone, and sure enough, it was hot, what was hidden behind this stone door?

The invisible protective layer had no choice but to lean against the wall and stare at each other.

The five-colored snake crawled onto Mu Shishi's wrist, and the color changed to red at this time, red like red coral, transparent and translucent red.

Mu Shishi grabbed the five-colored snake and took a closer look, the red was more beautiful than the dark green.

The five-colored snake spit out the letter, turned its head to look at the stone gate, its tail wrapped around Mu Shishi's wrist, Xue Linglong flew around in the sky, and when she saw the five-colored snake's move, she fell down and stood on Mu Shishi's shoulder.

"You want to go in?" asked Xue Linglong on behalf of the five-colored snake.

"This invisible protective layer as soft as cotton, soft and hard does not eat ......" Before the words were finished, a glimmer of light flashed in Mu Shishi's eyes in a blink of an eye: "Do you have a way?"

Xue Linglong scratched her chest with her mouth, but her mouth raised: "I'm still ......"

"You're still underage, you know, you know, you don't have to keep talking about it, there's no way, no one will laugh at you. Mu Shishi hated her words to the extreme, and when she heard the words of the underage, she wanted to get angry!

"I didn't say I had a way, it was the five-colored snake that asked me to ask. Xue Linglong shook her head in displeasure, and then said angrily: "I'm still underage!"

Mu Shishi wanted to strangle her at this time, but instead, she saw the five-colored snake wrapped around her hand: "Do you have a way?"

The five-colored snake spat out the letter, nodded its head, wagged its tail, and stretched its head forward.

"What do you want to do?" Mu Shishi looked confused, she didn't understand snake language.

"She asked you to put her on the protective layer, which you don't understand, if it's really human beings who are verbal idiots. Xue Linglong shook her head, her eyes pruning at Mu Shishi, as if she was saying that you are a fool!

Mu Shishi suppressed the sullenness in her heart, didn't bother with her first, raised her hand and put the five-colored snake next to the soft protective layer.

When the five-colored snake touched the protective layer, it suddenly broke away from Mu Shishi's wrist, and her body sucked the protective layer steadily, so it seemed that the body of the five-colored snake seemed to be floating in the air.

Yan Mufei's eyes were fixed on the changes of the five-colored snake, and the belly of the five-colored snake floating in the air became more and more bulging, as if he was taking drugs in the Wutong Pavilion, and his stomach was bulging little by little.

He stretched out his hand to touch it, and the protective layer below suddenly disappeared, Yan Mufei's eyes lit up, knowing that the five-colored snake could absorb drugs, but he didn't know that he could also absorb the invisible protective layer.

In a few minutes, the body of the five-colored snake was swollen like a ball again, and when the five-colored snake fell to the ground, the invisible protection of Chengwu disappeared immediately.

Mu Shishi held the little snake on the ground in her hand, and admired it in her eyes, this snake can suck anything when it comes!

Without the protective layer, the seven fruits on the stone door were even more concave, Mu Shishi stretched out her hand, and water stains appeared on the stone door, she withdrew her hand, and the water stains flowed down the seven fruits.

"This stone gate is mysterious, and it takes a lot of effort to crack it. Yan Mufei frowned, he could only see that it was a battle, but he didn't know the origin of this formation, and the seven fruit words were mysterious at every moment.
