Mu Zilei ran over to the light source, and the closer he got closer, the more cold he felt. But he was not the only one running towards the light source, more and more evil spirits were gliding and gathering along the way, but none of these evil spirits were interested in the humans around them, as if in their eyes, Mu Zilei was transparent.

He was caught between a multitude of cold-blooded creatures that radiated endless cold, and even his teeth shivered. But he had another strange feeling, these terrifying creatures that terrified the Atlas people, as if they were his close relatives, just like humans and orangutans.

Approaching the entrance of the cave, Mu Zilei had clearly heard the whirring sound of those evil spirits flying in mid-air, and there were screams one after another.

He made his way through the long cavern and fell into the bright light. The abrupt change in light made him unable to see for several seconds. When he got used to it, he saw himself in a huge cavern surrounded by thin ice. The cave was connected by three tunnels, and Duanmu'an and his group were at the entrance of another cave in front of the left, trapped in the frenzied siege of the evil spirits.

Duanmu An looked at Mu Zilei through the dense evil spirits with a look of disbelief. An evil spirit took advantage of his distraction and approached a few inches, and he had to retract his gaze.

The original team of more than 30 people is now less than half left. Everyone formed a circle and walked slowly and easily towards the center of the cave in front of them.

They seemed to have used some kind of mysterious group surname soul fusion technique, and the spiritual power aura on each person's body was closely connected together, and it was dazzling.

Powerful aura fluctuations continued to radiate out from the circle they formed, impacting the evil spirits that wanted to approach or attack, constantly rolling in mid-air, but some evil spirits also took the opportunity to absorb the spiritual power contained in the shock wave to reduce the buffer force and gradually approach.

Most of the fat people's faces turned pale, and every time the shock wave was launched, their aura was weakened by a point, obviously this spirit melting technique was quite consuming their energy, Mu Zilei found that although the aura fluctuations were circles, the power emitted from each place was not consistent. Especially with Duanmu'an as the center, the shock wave emitted by the five or six people who walked at the forefront was extremely strong, while the rest of the people were obviously inferior.

The demons seem to be smarter than they think, and they take advantage of the weakness of their prey's uneven strength and work together. Most of them kept turning and wrapping around, while the rest specially selected some weak points to launch a fierce attack, and their souls continued to condense into all kinds of weapons, including iron chains, broadswords, swords, and even stone-shaped, all of which were smashed in one place like a wild explosion.

The target chosen by the evil spirit often does not last long, and then it is unable to be held by the evil spirit's spirit, and is pulled out of the circular human wall, followed by a helpless scream and a creepy sucking sound. But the others finally didn't mess up, and every time someone was unfortunately pulled away by the evil spirit, the two people next to them would immediately gather together to fill in the gap.

Mu Zilei felt sincere pity for those victims and Duanmu An's predicament, but he really couldn't help it, and although he always thought that Duanmu An was the one who guarded the Fang Society, he couldn't tell whether they were enemies or friends, at the entrance of the formation, he had already died once for no reason, and he didn't want to die a second time.

He looked back at the center of the cavern, where a square, dull stone was placed. From the direction in which Duanmu'an and they were heading, the goal seemed to be exactly that.

A thought like an electric shock flashed, and Mu Zilei's heart was pounding. Could this be the legendary ashlar?

At this moment, a shadow appeared in another cave in front of the right, Mu Zilei thought it was just another fat man, but after the man walked out of the cave, he found that it was Lin Dumb, who had been missing.

Mu Zilei was vigilant, he hadn't forgotten his identity as a thief and pretending to be Lin Dumb and slaughtering Lin Shicun.

However, Lin looked quite weak, his face was pale, and his steps were swaying, as if he would fall to the ground next, blood was constantly flowing from his nose, he wiped it, but more blood gushed out.

His presence caught the attention of several evil spirits, who spun their guns and slid straight towards the new intruder.

Just as they were about to get in front of them, Lin Dumb suddenly took out a bottle of potion from his body and poured it into his mouth. After a convulsion, he fell to his knees in agony. He stared at the dull cube and struggled to get back to his feet, moving forward step by step. His steps were even more faltering, and this time even the corners of his mouth were bleeding. The evil spirit kept gliding around his thin body, but it didn't fly close to absorb his spiritual power.

At this time, Duanmu'an and his group, Lin Dumb and Mu Zilei happened to be in the three corners of the cave, and they all sensed the existence and intentions of the other party.

Duanmu'an's side was the first to change, he saw his companions die one by one, and the circle formed became smaller and smaller, he immediately whispered to the people on the left and right, and the two nodded, turned their heads to the other side, and passed their messages to the next person respectively.

In the blink of an eye, the original ten or so people's soul melting skills were cut off from the middle, Duanmu An took the five strongest people to form a new circle, and before the rest of them could react, they were rushed by the evil spirits in all directions, and in a few seconds, they were cut by the evil spirits one by one and drowned in a black shadow.

Those who were ruthlessly abandoned and sacrificed attracted the vast majority of evil spirits, and the sudden decrease in pressure made Duanmu An's speed greatly increase, and on the other side, Lin Dumb gritted his teeth and dragged his weak body forward with a stumbling forward.

However, the final victor was not them, but the strong Mu Zilei who ran all the way to the center of the cave unimpeded.

The stone in front of him was not as light as a feather, smooth as silk, and as bright as a diamond, as the chief said, but in fact it was a dull, rough and bulky stone. He looked around the ashlar and found a six-pointed star carved on the other side of the stone.

A clicking sound came from the ground, Mu Zilei let go of the soles of his feet, and there were several handfuls of strangely shaped metal scattered under his eyes, he squatted down and picked up one of them and looked at them carefully - the front end was a triangular shape, the middle was slender, and the tail end was a square, except for the deviation of the position of the triangle and the square, they were almost identical, and no more, no less, just six.

Could this be the legendary six keys that were needed to open the ashlar? Wasn't it always in the hands of the thieves? How could it appear here? Mu Zilei was puzzled.

"Give me the key!" Lin Dumb finally approached, stretched out his hand to snatch the key from Mu Zilei's hand, but he threw himself into the air, his body could no longer support it, and he stumbled and fell to the ground, panting for air.

"Zilei, you know what happened in the crystal secret. I'm a member of the Guardian Society, so give me the key. On the other side, Duanmu'an also came to the center of the cave despite all difficulties, and they were still in a circle, struggling to support themselves.

"When you were in the formation just now, but without saying a word, you asked someone to kill me," Mu Zilei was unmoved, "Killing people at will and dealing with friends indiscriminately is the style of your Shoufang Society?"

"At that time, the situation was critical, and we thought you were in league with Dumb Lin. ”

This explanation obviously did not make Mu Zilei relieved, he ignored Duanmu An, and studied this square stone by himself.

But there was not much time left for him, and more and more evil spirits poured in from the three tunnels, and the surrounding black pressure was overwhelming, completely sealing all the exits.

The circle formed by Duanmu'an has become the target of everyone, and it has already been surrounded by evil spirits inside and out for several layers, even if they can still resist it with the aura shock wave generated by the Spirit Melting Technique, it seems that the power is getting weaker and weaker.

For Mu Zilei, his biggest threat was the rapidly dropping temperature brought about by the continuous accumulation of evil spirits, he felt that the blood was about to freeze and condense, and the aura of Lin Dumb who fell to the ground was getting weaker and weaker, and the blood that flowed out had frozen into blood crystals in less than a while.

"Use those keys to open the ashlar, or we'll all die here. Duanmu'an's hurried voice came from the layers of evil spirits.

Mu Zilei absolutely agreed, but he didn't know where to start, this square stone didn't have a keyhole or a secret grid or anything like that.

"How?" he struggled to spat out his frozen lips, "there's no place on the stone for a key. ”

Duanmu'an was silent.

There were so many evil spirits in mid-air that they were crowded in front of them, Mu Zilei felt that there were evil spirits constantly brushing his face, and his limbs began to stiffen, and if he continued like this, he would freeze to death.

"Star ......" The weak voice came from the dying Lin Dumb who fell to the ground.

"What?"

"Stars...... Stone...... Head ......"

The words that once appeared in the crystal secret room flashed in Mu Zilei's mind-

When the stars return to the embrace of the stone, the ashlar turns, the door of light will open, and you will gain extraordinary power, but you will be cursed.

He hurriedly compared the six-pointed star pattern on the ashlar stone with the six keys, and found that the triangle on the key matched the size of the six corners on the six-pointed star map.

He trembled and overlapped the squares at the ends of the six keys, and a complete six-pointed star pattern appeared. Without hesitation, he pressed it on the six-pointed star of the ashlar ......;
