Hearing Ian's inquiry, Alexander's face revealed a complex expression as he slowly took out an item from his bosom and carefully displayed it in front of the crowd.
It was a crystal clear diamond-shaped crystal with a smooth and translucent surface that reflected a soft luster. Strangely enough, despite looking extremely delicate, the crystal itself was devoid of any energy fluctuations and appeared flat.
Adrian stared at this diamond-shaped crystal with some puzzlement, looked it up and down, and frowned with dissatisfaction: ''Is this the thing that caused you guys to be besieged by mutant beasts? It looks too ordinary!"
Alexander shook his head with a bitter smile, "We thought so too, but the truth is, when we just removed this crystal, the mutant beasts immediately came from all directions, as if they sensed something important being taken away."
"System, do you know what this is?" Ian silently asked the system in his heart.
[The crystal is the key to leaving the relics, please ask the host to explore on his own for the specific method of use]. Ian was already not surprised by the system's staged mystery.
Ian thoughtfully took the diamond-shaped crystal and scrutinized it carefully, "It does look ordinary, but there might be some secret that we can't see."
Adrian bristled, "Let's hope so, or else we've wasted so much time and almost got all of us involved for nothing."
Alexander sighed slightly, "Regardless, this crystal must have an important value that we have yet to discover, otherwise those mutant beasts would never have gone so crazy."
Ian nodded solemnly and handed the diamond-shaped crystal back to Alexander, "Keep it safe for now, and when we get out, we'll study it more carefully, maybe we can really find some useful clues."
After briefly recuperating, the group quickly regained their strength and decided to continue towards the huge building at the center of the ruins.
As they gradually approached the central area, more survivors gradually gathered along the way, and the crowd formed groups to move forward. Along the way, members of the various forces were also communicating with each other, and there was a clear difference from the once hostile state, so it could be seen that the series of events from joining forces to guard the City of Ashes to exploring the ruins had made the three forces become more like a whole.
However, what made Ian feel a little worried was that they never saw any sign of William along the way.
Adrian noticed Ian's worries and comforted him in a low voice, "Don't worry too much, William's strength is so strong, nothing will happen, maybe he has already arrived at the center building ahead of time."
Ian gently nodded, but still couldn't completely let go of his worries about William in his heart. He knew deep down that the interior of this relic was full of unknown dangers, and even if he was as strong as William, he might not be able to deal with all the threats unharmed.
After some difficult trekking, the crowd finally arrived at the huge building in the center area. The building was majestic and towering into the clouds, the surface of the building was carved with complex runes and reliefs, exuding a thick and mysterious aura.
Alexander gazed at the building in front of him, his face solemn, "It seems that this is the core area of the relics, everyone be careful."
The crowd entered the building and quickly started exploring. What made them feel strange was that although the interior of the building was covered with ancient runes and strange statues, they did not encounter too many enemies.
The few mutant beasts that occasionally appeared were not very strong, and were quickly and easily resolved.
Adrian couldn't help but wonder, "It's a bit too quiet here, it's not as dangerous as the previous area, instead it's a bit spooky."
Ian frowned slightly, "Indeed, we must be vigilant, this abnormal quietness often means that greater threats are lurking in the shadows. For example, that powerful mutant beast."
Soon, they arrived at a huge stone door along the wide corridor. The stone door was about tens of meters high, carved with complex runes and patterns, and the surface was covered with a faint layer of energy fluctuations, clearly not an ordinary stone door.
Adrian reached out and gently touched the stone door, and immediately felt a strong resistance pushing his hand away.
"It seems that this door is not easy to open." Adrian frowned, "The runes on it are complicated, perhaps another mechanism that needs to be broken."
Alexander nodded, "This should be the most central area of the building, and it may hold the greatest secret of the ruins."
Ian scrutinized the runes on the stone door and pondered for a moment before saying, "I think we need to figure out the meaning of these runes first, perhaps we can find a way to open the stone door."
Adrian sighed, "Another brain job, this relic can be a real tosser."
Ian smiled slightly, "This time it's not something that can be solved by brute force, we have to work together."
The crowd gathered together and began to scrutinize the runes and patterns on the stone door, hoping to find the key clues to open this mysterious door.
However, just as they were fully concentrating on studying the runes, the runes on the surface of the stone door suddenly lit up with a faint glow and slowly began to change form, as if responding to the crowd's exploration.
All of them immediately raised their alertness and stood on guard, ready to face the unknown challenges behind the stone door. The stone door slowly opened, revealing the darkness behind it, and as the crowd prepared themselves and were about to enter the door, Ian, as if sensing something, shouted, "Watch out!"
A huge sword qi rushed out from the darkness, Adrian who was at the front quickly reacted, his shadow power instantly erupted, "Battle Technique - Shadow Stab!" Adrian directly launched the strongest strike. The two energies collided, Adrian was knocked back several meters by the resulting shockwave, after stabilizing his body Adrian was surprised, "So strong!"
The crowd stared at the darkness behind the stone door, a figure holding a huge sword slowly walked out, Ian's pupils instantly tightened when he saw the figure's face!
