"Young Master, what's going on?" Brother Biao looked at Lin Nantian and felt that Lin Nantian was strange at this moment, and couldn't help but ask.

Lin Nantian said strangely: "No, I always feel strange."

Brother Biao looked ahead and said, "This place is weird."

"But, this place is not the strange thing." Lin Nantian said. He felt that Brother Biao was very strange.

"Oh?" Brother Biao asked, "Where is that weird?"

Lin Nantian pointed at Brother Biao and said, "It's you who blamed me."

Brother Biao suddenly looked stunned, very strange. He looked at Lin Nantian and asked, "Young Master, are you okay?"

Lin Nantian shook his head and said, "If you are not surprised, why do you know there is room here?"

Brother Biao looked at the space and frowned and said, "This was also discovered by chance, so I pulled you in..."

Lin Nantian shook his head, always feeling something was wrong, and said, "But, how did you know that after entering this hole, the invisible person can't get in?"

Brother Biao pointed to the entrance of the cave and said, "The entrance of the cave is so big, the invisible person, when I chopped it off just now, I felt that the thing was very big."

"So that's it." Lin Nantian listened, and thought about the fact that the thing was really big when he grabbed him. It was just strange that why can't this thing be seen?

"Is this invisible thing an invisible person?" Lin Nantian murmured to himself.

"Dongdong..." Suddenly, Lin Nantian and Brother Biao heard the sound of metal knocking on the door.

Looking at the sound, Lin Nantian and Brother Biao were shocked and saw that there was a strange metal door in this space.

Looking at this space, Lin Nantian and Brother Biao were surprised at the same time.

They showed a terrified expression that was as if they had seen a strange monster.

At this time, the "dongdong" sound came to an abrupt end.

There was no sound at all without warning!

After a long time, Lin Nantian said, "Is this door too weird?"

Brother Biao nodded and said, "Yes."

Lin Nantian walked over, looked at it for a long time, and said, "What is this?"

Brother Biao asked in confusion at this time: "It seems like this is a metal door. The sound just now came from here. Who is there?"

Lin Nantian shook his head, but his eyes were a little weird and said, "Can there be someone invisible here? The person who was invisible was knocking on the metal just now?"

Brother Biao looked at Lin Nantian and laughed, saying, "How is it possible that the invisible person is on that secret passage, how could he run to this place?"

Indeed, in this small space, in addition to the hole that just came in, there was a secret passage outside, and there was also an invisible person in the space inside the metal door on the wall inside.

Unless the space inside the metal door here is connected to the secret passage just now, it cannot be said that the invisible person is knocking on the door.

Lin Nantian looked at it and couldn't help but say, "That's strange, who is knocking on the door?"

Brother Biao said at this time: "Young Master, could it be the Fourth Master and the others?"

When Lin Nantian heard this, he couldn't help but remember the scene when he and his friend suddenly disappeared, and then said, "It's impossible. They didn't even walk into this place, how could they be there?"

Brother Biao thought for a while and said, "Although that's the case, you can see that there are only wrinkled ground in that space and you can't see whose footprints it is. Maybe some of the footprints are theirs? They entered the door.

The channels are actually connected.”

When Lin Nantian heard this, he felt that it might be like this, otherwise he would really not be able to explain these things.

He couldn't help but say, "Hey, we just entered the tomb at that time, and we didn't notice much about whether their footprints were leading to other places on the ground. But after thinking about it, if there were no other footprints, it would make no sense.

, It seems that it is really possible that their footprints are also in the middle."

Brother Biao nodded and said, "That's all, otherwise the Fourth Master and the others can really disappear out of thin air?"

Lin Nantian thought for a while, smiled, and said, "Maybe, there is another possibility that he really disappeared out of thin air."

Brother Biao said blankly: "Why did you say it disappeared out of thin air?"

Lin Nantian said: "You also saw that there were only two roads in front of the space before, but their footprints seemed to have never walked. So it was obvious that they disappeared out of thin air in that space."

Brother Biao nodded quickly when he heard this and said, "You are talking about the young master. Your thinking is getting more and more agile now."

"Hehe, what agility is, it's not something you can think of with your ideas." Lin Nantian said with a smile.

"Shh." Brother Biao suddenly made a gesture of making some noises and said, "Listen, there is movement in this metal door again."

"What?" Lin Nantian pressed his ear against the metal door, but heard nothing.

Brother Biao pulled Lin Nantian away at this time and asked Lin Nantian to see it quickly.

"Huh?" Lin Nantianding looked at it and suddenly saw that the metal door actually vibrated slightly.

"Damn. Is there really someone in this sect?" Lin Nantian was surprised.

"Speak quietly, it seems that something is listening to us." Brother Biao said in a low voice.

"Dongdong." Suddenly, the iron metal door rang again, and the sound made was very strange.

"Damn, my ears are almost deaf." Lin Nantian couldn't stand the sound and hurriedly covered his ears with his hands.

"Yeah?" Brother Biao was stunned at this time.

"What's wrong?" Lin Nantian couldn't help asking, looking at his strange expression.

Brother Biao waved to Lin Nantian and said that his voice stopped, and then pointed to the metal door in front.

Lin Nantian took his hand away from his ear and heard Brother Biao say, "This is not a metal door."

Lin Nantian heard this and asked, "No, then what's this thing?"

Brother Biao said excitedly: "If that's right, this is a musical instrument. But I have never seen it before, it's so big."

Lin Nantian looked at the metal door in shock and shook his head and said, "Impossible, how could this look like a musical instrument?"

Brother Biao said, "Young Master, take a closer look. This door is not flat at all, it is obviously curved."

"It's true." Lin Nantian nodded and found that this was indeed not a door. It was a large metal embedded in the wall.

He turned his head, looked at Brother Biao, and said, "How come this is indeed a musical instrument?"

Brother Biao said little by little, "Don't you think?"

Lin Nantian smiled and said, "Who in the world today uses iron as musical instruments?" Lin Nantian couldn't help laughing as he thought, looking at the rust on it, and he had never heard of it in his image, iron too

Can be used as musical instruments.
