The tall and heavy stone gate slowly opened, making a dull sound, Wu Yuhan glanced at the Ning Xin sisters and brothers who were standing still, and without saying anything, he took the Wu family monk into the stone gate.

"Sister, why do I think Wu Yuhan seems to be very familiar with this stone gate!" They searched for a long time but didn't find the switch to open the stone door, and Wu Yuhan found it as soon as he came, which made Mu Ningyi feel very strange!

"She may have a talent for this, let's go, let's go in too!" Ning Xin said casually, looking up at the night sky that was still clearly visible, the ninth round of blood moon was only a small gap before it was complete!

"After entering, be careful, that Demon King may appear at any time!" The reason why Wu Yuhan opened the stone gate so happily was probably to buy time, on the one hand, it was estimated that after they entered the stone gate, if the Demon King suddenly appeared, they could also help block it by the way!

"Hmm!"

The two of them quickly walked into the stone door, and as soon as they entered, the stone door creaked and closed, and the speed of closing the door was much faster than when the door was opened!

After entering the stone gate, there was another stone cave that was even more open, constantly extending downward, with no end in sight, and Ning Xin and Ning Yi were now standing on a stone wall that was only a few meters long!

A huge red flame burned in the center of the cave, illuminating the upper part of the cave!

At the edge of the stone wall is a circle of stone stairs only one meter wide, which continue to wind downward, and a small cluster of red flames burns on each stone staircase!

At this time, Wu Yuhan and the Wu family monk had already descended several circles of stone stairs!

Ning Xin stared at the Wu family monk for a while, then looked at the burning red flame, and quickly took out a pill!

"Take the pill!"

Ning Yi took the pill, didn't say anything, and took it directly, before asking, "Sister, is there anything wrong here?"

"Looking at these red flames for a long time will make you lose your mind!" Ning Xin said that, she walked down the stone stairs, and Ning Yi immediately followed.

Hearing this, Ning Yi's eyes flashed, and he looked at Wu Yuhan and the others who were steadily moving forward under a few laps, and felt a little depressed in his heart, no wonder Wu Yuhan opened the stone door so easily, it turned out that he was waiting for them here!

It could be seen that they knew the effect of this flame, but they didn't tell them, their hearts could be punished!

Ning Xin looked at her younger brother with an ugly face, and instantly knew what he was thinking in his heart, "People are not obliged to tell us about potential dangers, if they really fall into a crisis, they can only blame themselves for not having enough experience and lack of strength!"

"I see!"

After that, the speed of Ning Xin's sister and brother was neither fast nor slow, and they kept a certain distance from the Wu family monks!

As time passed, the call in Ning Xin Ning Yi's heart became clearer and clearer, and the two of them knew that the fragment was nearby!

At the bottom of the stone stairs, the stone walls are full of stone caves that don't know where they lead, when the Ning Xin sisters and brothers came down, the Wujia monk was gone, and the two were not surprised by this!

Ning Xin closed her eyes and sensed it, and walked directly into one of the stone caves with Ning Yi!

The stone cave is a staggered vertical and horizontal passage, walking in it is like entering a labyrinth, if it is not for the induction of fragments, Ning Xin cannot guarantee that she can get out of the stone cave smoothly!

"Sister, look, there are marks in this passage!" Ning Yi said, pointing to an inconspicuous red mark on the top of the stone wall.

Ning Xin nodded, she also noticed that the passage they walked through seemed to have such markings, "These are probably the markers that guide the orcs to the location of the fragments!"

At the same time, the monk of the Wu family was following behind Wu Yuhan in a daze, quickly shuttling through the stone cave passage that was also marked with red markings!

Wu Yuhan looked a little anxious, the speed under his feet became faster and faster, and the fluctuations of the fierce qi in the stone cave began to gradually slow down, which indicated that the cultivation of the Demon Demon King had entered the end, and it was possible to end the cultivation at any time!

The Demon King who has been refined into the Heavenly Demon Beast Immortal Determination is definitely not something they can match, and they must leave the Demon Demon Cave before that fragment!

After a period of twists and turns, Ning Xin and the Wu family monk entered a huge cave almost at the same time!

For the first time, Ning Xin and Wu Yuhan's eyes met in the air, and the two of them were a little surprised but not surprised in their eyes!

The two of them immediately turned their eyes to the fire pool burning with red flames in the center of the cave, the stone basin containing the blue liquid suspended above the fire pool, and the purple fragment above the stone basin!

The cave was filled with a soft purple light, and there was not a trace of red light to be found!

Although the fragment was only the size of a fist, the purple light it emitted still overwhelmingly completely covered the red flames in the fire pool!

Ning Xin's eyes were firmly fixed on the blue liquid above the flames, and her expression changed a little!

As soon as she entered the cave, she found that the purple light inside was different from the previous fragments!

The purple light emitted by other fragments was obviously aggressive, and ordinary people couldn't get close to it at all, let alone absorb the energy inside!

And the purple light in this stone cave is not only not aggressive, but also very soft, no need to try, she also knows that this purple light can be absorbed at will, just look at the Wu family monks who looked excited on the side can determine this!

No wonder the strength of the orcs has grown so fast, and the Demon King probably let the orcs absorb the purple light!

The change of purple light is definitely the same as the blue liquid in the stone basin, but what is that blue liquid? It has such a strong effect on purple light!

"That's the dustless divine water, the purple light emitted by the fragments has been washed by the divine water, and people can absorb it freely!" Xiao Bai's voice suddenly sounded in Ning Xin's mind!

"This dustless divine water sounds quite advanced, but why is there one here?"

"It's mostly related to the red flames in the fire pool!"

"Red Flame, that's a very apt name!" The red flames in the fire pool and the red flames they encountered after entering the stone gate before were all immortalized by absorbing the ferocious qi!

"The ferocious aura contained in the red fire is too strong, if it spreads out, I am afraid that there will be no living beings in this demon cave! The dustless divine water can suppress the fierce qi, and there is a balance between yin and yang between heaven and earth, it is estimated that this is the reason why the dustless divine water appears here!"

Wu Yuhan looked at Mu Ningxin, who had an unknown expression, and Mu Ningyi, who had been looking at the fragments for a long time, and forcefully stopped the Wu family monks who wanted to rush up to fight for the fragments immediately.

You can't fight with Mu Ningxin's sister and brother, otherwise it will definitely alarm the Demon King, and when the time comes, no one will want to leave!

"Mu Daoyou, I don't know what your plans are?"

"What are Wu Daoyou's plans?" Ning Xin raised her eyebrows and looked at Wu Yuhan, and the Wu family monk with an eager face.

"I hope Mu Daoyou can give us this fragment!"

"Why?" Ning Xin looked at Wu Yuhan in surprise.

"Because your younger brother Mu Ningyi once took away the amethyst fragments of our Wu family!"
