Everyone was in a false alarm, they had just entered this ruin, but they didn't expect to be disarmed by this crystal skull.

"Su Chen, are you still hot all over your body now?" Walker stared at Su Chen's body for a while, according to reason, Su Chen's body was so hot just now, but his clothes were intact, and there was no trace of curling up at all, which was a strange thing.

"I'm fine!" Su Chen took a look at his body and felt that there was nothing special, except for a little hallucination just now, it couldn't be better now.

"It's okay, only you can get the crystal skull among us, put it in that stone cave, and see if this door can be opened!" Walker gave the order, Lu Yi is not here, he is the absolute leadership core, of course, Lu Yi is here, and he can't change anything.

Su Chen came to the grotto that was not easy to find, looked at the outline of the grotto, and put the crystal skull in, in the process of putting the crystal skull in, Su Chen suddenly felt that it was sucked in by a suction force, the crystal skull slid in, and his body exploded back a few steps.

"Everyone be careful, I feel that this crystal skull is pulled into it by a force, it is very likely that there is something strange hidden behind the stone gate, prepare for battle!" Su Chen shouted.

The guns in everyone's hands were loaded and safed, Su Chen picked up the rifle he had placed on the ground before, Chiba Sakura stood in front of him, clenching the sword in his hand, their formation presented a classic defensive formation, melee in front, and long-range in the back.

Rumble......

The whole road began to shake, the dust on the stone wall kept falling, the ground trembled, and with a loud bang, everyone turned around, and a huge boulder gate fell behind them, completely sealing their original path.

"Sure enough, there is some mechanism! Will we burp!" Dio was nervous to death, his chain of gods did not allow him to carry out such a combat mission, and the only thing he could rely on now was the M4A1 rifle in his hand that had been modified by the equipment department.

"If you don't say a few words and kill a few more Strange Beasts, I don't think you will!" Yi Yi held the light sniper rifle in her hand, half-crouched to aim at the stone gate, and her calm quality like a professional sniper allowed her to maintain her best combat ability in any environment.

"If we hadn't died this time, we'd have been partners in life and death, wouldn't we?" Dior held M4's hand trembling slightly.

Yi glanced at Dio, "So what?"

"Shouldn't there be something, like a love trip to Italy, a game of castle stacking on the beach, a sea breeze on Walker's yacht, and relaxing?" Dior swallowed.

"If you were thinking about this right now, you'd probably go to the Yellow Springs to blow the wind!" Walker said coldly.

"Well, actually, I like your yacht!" Dior couldn't help but say bad things.

The stone door slowly opened in front of everyone, Dior's hand had already pressed the trigger a little, as long as it was thrown down, the muzzle of the gun would shoot flames, Chiba Sakura also clenched the sword, and the blade was cold, this was also the first time she came to the ruins to carry out a mission, and she had only heard her brother say how dangerous it was in the ruins before.

"Everyone, get ready!" Walker's "war zeal" has been unconsciously turned on, and as soon as a monster rushes out, the first thing to greet it is a gorgeous barrage of shooting.

The stone gate was slowly pulled up, and when it was halfway up, suddenly everyone felt the ground shaking violently under their feet.

"Is there an earthquake?" Dior's legs went limp, and an earthquake was not a good sign at this time.

"It's possible that the American continent where we are now is located in the Pacific Rim volcanic seismic belt, which is a place with frequent earthquakes, and the largest earthquake in human history has occurred here, the Chilean earthquake!" replied Xia Wanyu.

"There is also a possibility that there may be a dark layer on the ground beneath our feet, and the structure inside is changing, and these are things that often happen in the ruins!" Walker has a lot of experience in carrying out tasks, although he has never encountered it, but he has heard people in the family talk about it.

"Do you believe in Qimen Dunjia?" Su Chen suddenly asked.

"What do you mean?" Dior, as a European, apparently had not heard of it.

"This is a metaphysics in our country, and it is said that the last person who mastered such an ability was the strange Jiang Ziya. His "Qimen Dunjia" uses the operation of the nine stars and twenty-eight houses to reflect the transformation of the time and space fields and their relationships and laws with each other.

He uses gossip to embody the role of the space field. He once built a huge underground palace, and the underground palace uses such a moving structure to change its position at all times, and after entering, unless someone gives you a map and reminds you of the palace trajectory at all times, you don't want to come out alive!"

"Does this have anything to do with the place we're in now? Do you want to say that he built all the moving underground palaces in history?" Walker said.

"No, Qimen Dunjia is mainly used in the operation of celestial bodies and the laws of the operation of the universe, you think about what the Mayan civilization is best at!" Su Chen said here, and everyone suddenly shuddered.

"Astronomy!"

"That's right, it's astronomy, the Maya's achievements in astronomy are completely beyond the current level of human beings, so Qimen Dunjia is naturally not a noble thing in their eyes!" Su Chen licked his lips, he heard Walker talk about such a structure before he remembered that there was such a thing.

Rumble......

The stone door had been completely opened while everyone was talking, but it was not what everyone imagined, there were no monsters rushing out inside, but a dark passageway, and it was not known where it would lead.

"Hey, there's nothing scary! it's all about us!" Dior put down the gun in his hand, nervous for so long, and finally able to breathe a sigh of relief.

But before this breath could be released, suddenly there was a loud bang, accompanied by the screams of several people.

Rumble......

"Ahh

"Be careful!"

The ground where Su Chen, Chiba Sakura and Xia Wanyu were located collapsed, and Walker reacted quickly under the effect of the God's Chain and grabbed Xia Wanyou on the side, but Su Chen and Chiba Sakura fell.

"Suchen!" Yi yelled at the dark part of the dark part as he reached the massive collapse position, but there was no response.

"Bastard!" Walker pulled Xia Wanyu up and punched the stone wall on the side, and the hard stone wall actually cracked.

Before Dio came to his senses, the two of them were gone, and they were suddenly confused.

"What now?" Yi Yi frowned, they had already lost two of them before they had encountered any Strange Beasts and Inhumans, and it could be said that the losses in such a squad were heavy.

"Su Chen!Sakura, please reply if you receive it!" Walker shouted in the group's channel, their communication was now isolated from the outside world, but they were still able to communicate with each other in the ruins, but there was no sound from the other party.

Things got tricky, now there are only four people in the team, Lu Yi is not there, Chiba Sakura and Su Chen have fallen into a trap, life and death are uncertain, whether they want to continue to the ruins or choose to turn back.

"You can't give them up like this!" Xia Wanyou bit her pale lip, she almost fell down just now, she only felt that her body was suddenly weightless, and she couldn't exert her strength, and she didn't have time to react at all, it was just a moment's effort.

"We won't leave our partners behind, keep moving forward, even if we dig three feet into the ground, we have to find them!" Xia Wanyou chose to keep going, Walker naturally would not back down, the glory of the Andrew family has nurtured him since he was a child, and bravery and glory are buried deep in his heart.

"I'm with you!" echoed Yiyi.

"You've all said that, I don't have a choice!" Dior spread his hands, although he didn't seem to care, but in fact he was the most affectionate person in the whole team.

"Turn on the night vision! Keep going!" The remaining four people, under Walker's command, turned on the night vision function of the multi-function device, and could see as clearly as in the dark.

......

Tick... Tick...

In the dark and damp environment, the two men lay on a wet stone slab, and the cold water constantly washed their feet, gradually overflowing their calves and knees, and the surrounding was quiet and eerie except for the sound of running water and dripping.

The damp water dripped on Chiba Sakura's face, wetting her forehead, and the soles of Chiba Sakura's feet were numb and chilled from the cold water, and she woke up first, and she was now lying on a smooth stone slab, her feet soaked in water, and there was constantly flowing water from her knees.

"Ahh It's so cold..."Chiba Sakura picked up her thin body, and the air here made your lungs feel like it was going to freeze when you took a breath of air, which was almost like the cold snap in Siberia.

"Su Chen..."Chiba Sakura shouted weakly, she saw Su Chen lying on the ground like herself not far away, and slowly crawled over and shook his body.

"Wake up, wake up!" Chiba Sakura shook Su Chen's body, but Su Chen never knew whether he was lying dead or alive, Chiba Sakura touched his chest, fortunately his heart was still beating, he should just faint.

"Where is this?" Chiba Sakura only remembered that she suddenly lost weight on the soles of her feet, and the whole person fell, and then she fell and fainted, and then woke up to find herself lying in a dark and damp place.

"Walker!Walker!" Chiba Sakura tuned into the "Renaissance" mission team channel.

"Sakura, are you alright?" Fortunately, the other end quickly gave Chiba Sakura a reply, which made her feel a little more at ease, at least she still had a connection with the world, and it was much better than dragging an unconscious oil bottle alone miserably.

"It's okay! We're in an underground river now, it's so cold here!" Chiba Sakura's body was trembling slightly when she spoke, the temperature here seemed to be close to freezing, Chiba Sakura was still wearing summer clothes, although the physique of the Alien was much better than that of ordinary people, but she couldn't help the cold for a long time.

"We're going to you, do you have any iconic things there?" Walker said on the other end of the line.

"Here... There are a lot of stalactites here, eh! There seems to be a lot of glowing things in the distance!" Chiba Sakura walked forward, and when she walked to the glowing place, her mouth couldn't help but open wide.

"There's a lot here... It's like a pool made of crystal!" Chiba Sakura said incredulously as she looked at the shiny crystals inside.

"Crystal?" Walker wondered.

"It's the crystal pool!" Xia Wanyou on the side suddenly thought of something.
