The card had turned pitch-black, as if it had been dyed by thick ink. The pattern in the middle was indistinct, as if it had been deliberately erased by a pair of invisible hands.
However, Lin Bai felt that the shape was like an eye, and he had seen it somewhere before. He could not help but think of the huge beast eyes he had seen on the sculpture.
Initially, he did not feel anything when he held the card. It was light and weightless, as if it did not exist. However, it had become bone-chilling and much heavier now.
Lin Bai could not help but suspect that this plate might not belong to Qian Ran and the others. Moreover, it had some mysterious connection with this cave.
Just as Lin Bai was sizing up the card in his hand, the black fog that had been lurking in the dark moved. Lin Bai did not see that the sticky substance in the dark began to become active, just like the shadow monsters that had been nurtured previously.
However, at this moment, they began to fight to get into the sign. Lin Bai felt his hand sink. The sign that was originally only a little heavy now seemed to weigh a thousand pounds. It was so heavy that he almost dropped it on the ground.
“How could it be so heavy?”
Then, the pattern on the sign became clearer and clearer. It was as if the fog that had been shrouding the sign had finally been blown away. However, the pattern that was revealed was not what he had seen previously.
Scattered lines scattered in all directions. They looked messy, but in fact, there was a certain pattern. They were intertwined. Lin Bai looked at them for a moment, and no matter how he looked at them, they looked like a map.
This card had always been quiet and nothing unusual. Now that he was in this cave, it seemed like it had been awakened by something. Could it be that the content displayed on the sign was the map of this cave?
Lin Bai held the thought of giving it a try and walked forward according to the directions on the sign. As expected, there was an intersection. “It really is a map.”
There was an asterisk on the card. He didn’t know what it meant, but there were no other paths. It could be imagined how special this place was. Lin Bai couldn’t help but have a guess.
This was a forbidden area. There were either things that could not be seen by others, or there was some kind of being locked up. In addition to that powerful maze, there was also the shadow monster that could not be killed and could split up in the cave.
Lin Bai, who was deep in thought, did not realize that his eyes were covered with a faint layer of black gas. At the same time, there was a voice in his heart calling him over.
All the signs indicated that there was a special existence in this cave. Out of curiosity, Lin Bai could not help but walk towards the location of the asterisk.
After making this decision, the black smoke in Lin Bai’s eyes faded like a tide. All of this passed in an instant without Lin Bai even noticing.
Perhaps it was because of the map or something else, Lin Bai actually did not encounter any danger along the way. Even the shadow monster that was chasing him like a dog did not chase after him anymore.
However, he did not see that puddle of black sticky substance. It was like a maggot in the tarsal bone, following him like a shadow. It also seemed to be monitoring his every move.
As Lin Bai moved forward, the scene in front of him became more and more open. The narrow road seemed to have finally come to an end, revealing a weak light.
It was like a long night. Finally, a bright lamp appeared, dispelling the endless darkness and cold. It meant that the light had once again descended on the Earth. Lin Bai could not help but quicken his pace.
The increasingly intense light was somewhat dazzling. After all, he had been in a dim environment before, so he was not used to it. He could only raise his hand to block it. When he put down his hand, he could clearly see the scene in front of him.
What appeared in front of him was an incomparably huge door. The light was coming from inside. At the same time, he could faintly hear the sound of someone speaking from behind the door. It was as if someone was talking inside.
That voice was Fool Li’s voice! It was just that he could not hear clearly what he was saying.
Lin Bai was shocked. How did Fool Li suddenly run behind the door? And how did he open the door.
He tried to see more clearly through the crack, but all he could see was a brilliant white light. Other than that, he couldn’t see anything else.
The door looked old. Lin Bai couldn’t help but touch it. The feeling on his hand was extremely rough, as if it was made of an unknown bronze material and had been standing there for thousands of years.
There were complicated patterns drawn on it, as if it was some kind of array formation. However, he wasn’t sure. These patterns extended all the way inside, as if it covered the entire cave. At the same time, there were some small grooves, he did not know what they were used for.
Lin Bai tried to push the door, but it did not move at all. No spiritual power could be used on it. Little Green and Little Red also activated their spiritual power, but the result was still the same.
He took out his most powerful Ruoshui sword. The sword qi was wanton and cold. However, it couldn’t even make a white mark on it much less open it. Lin Bai sighed at the sturdiness of the door.
It seemed that it would be impossible to open it with violence.
Lin Bai looked around. There was a groove in the center of the gate. It seemed to lack a mechanism to activate it. He observed carefully and found that the position of the groove was somewhat compatible with the card in his hand.
Lin Bai put the card on it. It was actually perfectly compatible with the card. It was simply unbelievable.
“Rumble!”
A loud sound was heard. Along with the sound of the cave shaking, white spots of light appeared in the groove. Like fireflies, they appeared on the door. Then, the spots connected into a line, and countless threads converged, forming a mysterious pattern.
Countless gears spun, and the door was finally opened.
