Chapter 769 Zhang Meng's Clever Tactics and the "Mysterious Key"

"I'm really too tired!" Zhang Meng sat on the ground, hugged his knees, and looked helpless. "Qin Feng, can you tell me how long it will take for us to end this nightmare?"

Ye Li was checking her equipment while teasing, "You still expect it to end? Every time you say you're tired, there's definitely something worse waiting for us next."

Chu Tian smiled and said, "That's right. Every time you complain about being tired, I feel like we're getting closer to trouble. Why don't you just stop talking this time, and maybe we'll be fine."

Zhang Meng rolled his eyes. "You can make fun of me all you want, but I'm really scared of this damn place. Every step I take, I feel like my life is hanging by a thread."

Qin Feng watched them joking and couldn't help laughing, but he knew that the road ahead might be even more difficult. He took a deep breath, stood up, and walked to the still flashing energy ball with a serious look.

"Everyone, don't relax yet. Although we have gotten rid of the illusion, the real trouble has not been solved yet." Qin Feng said calmly, "The mystery of this energy ball has not been solved yet."

Zhang Meng frowned, stood up, and dusted off his body: "What should we do? We can't just stare at it, right? How about... smash it again?"

Ye Li rolled her eyes: "You almost sent us away last time, and you still dare to smash it?"

Zhang Meng scratched his head and said with a silly smile: "How do you know if you don't try?"

"If you hit it again, you might not even have a chance to run away." Chu Tian said with a smile, "This thing is not that simple."

Qin Feng smiled helplessly: "I guess brute force alone is useless. This energy ball seems to have some connection with the symbol we saw before. There may be some mechanism hidden inside it."

"Mechanism? Are you talking about the password?" Ye Li frowned, her eyes sharpened, "If so, we have to find the key to unlock it."

Qin Feng nodded: "I think it should be some kind of 'key'. Maybe we need to find the real secret of this space."

Zhang Meng looked puzzled: "Key? Where should we find it?"

Qin Feng looked around, and his eyes fell on a wall that was faintly glowing. He walked over and took a closer look, and found that the wall was engraved with complex symbols and patterns, some of which seemed similar to the ones they had seen in the stone pillars before.

"These symbols... I have a hunch that they might be clues." Qin Feng gently touched the wall with his hand, carefully observing every detail.

Chu Tian came over and said, "Are you saying that the key we are looking for is on this wall?"

Qin Feng nodded: "Yes, look at the arrangement of these symbols, they seem to be guiding us to find something."

Ye Li also came over, her eyes solemn: "Perhaps there is some kind of guidance hidden in this space. As long as we follow the clues of these symbols, we should be able to find the real answer."

"Then what are we waiting for? Let's find it quickly!" Zhang Meng suddenly became energetic, "I must make a contribution this time!"

"Don't mess around!" Qin Feng grabbed him and said with a smile, "You said the same thing last time, and you almost got us all sent away."

"I have a plan this time!" Zhang Meng said mysteriously.

"What plan?" Ye Li and Chu Tian asked at the same time.

Zhang Meng proudly pulled out a small compass from his arms: "Hey, see? This is what I picked up in the cellar last time. This thing is very smart! I used it to find the direction just now, and I found that it moves with the changes of these symbols!"

Qin Feng was stunned for a moment, and suddenly understood something: "You mean, this compass can sense the changes in symbols?"

Zhang Meng nodded proudly: "That's right! I tried it, and the direction the compass points to seems to correspond to the arrangement of these symbols. So I guess, just follow it, it must be right!"

"You are so lucky." Chu Tian couldn't help laughing, "You can come across something like this."

Ye Li's eyes lit up: "If Zhang Meng's guess is correct, then this compass can indeed lead us to the right path."

Qin Feng thought deeply for a while, nodded and said: "Then let's give it a try."

They followed the compass in Zhang Meng's hand and gradually explored every corner of the hall. As they continued to move forward, the light of the energy ball seemed to become dimmer and dimmer, as if waiting for some critical moment to come.

Suddenly, Zhang Meng stopped and said, "Look here!"

He pointed to a certain spot on the wall, where a faint light appeared. Qin Feng walked forward and found that it was a very small gap, which seemed to be a hidden door.

"This... is the key to the answer to the mystery." Qin Feng said in a low voice.

"Great, we found the entrance!" Zhang Meng jumped up excitedly, "I knew my compass was useful!"

"Don't be too happy too soon." Ye Li reminded, "There may be something more dangerous behind the door."

Qin Feng gently pushed open the hidden door, and a chill hit him. Behind the door was a narrow passage, and the walls on both sides of the passage were also engraved with complex symbols, as if welcoming their arrival.

"Everyone be careful." Qin Feng said vigilantly, "The weirder this place is, the closer it may be to the real secret."

They walked cautiously along the passage. It was terribly quiet, as if something unexpected might happen at any time. After walking for about a few minutes, they finally saw an open space at the end of the passage.

This is an ancient room. In the center of the room stands a huge stone tablet, which is engraved with mysterious symbols. In front of the stone tablet, a strange metal key is suspended, flashing a faint golden light.

"That's the key!" Ye Li recognized it at a glance and said excitedly.

"It's right this time!" Zhang Meng walked forward proudly and reached out to grab the key.

"Wait!" Qin Feng stopped him, "Don't move! How can this thing be so simple!"

Ye Li carefully observed the stone tablet and found that the symbols on it seemed to be telling some kind of warning: "This stone tablet seems to be... a warning. If we take the key rashly, it may trigger some kind of mechanism."

"It's another trap..." Zhang Meng scratched his head, the smug look on his face gradually disappearing, "I won't dare to move this time."

Qin Feng smiled and said, "That's right. Let's first see how to crack the mechanism on this stone tablet."

After careful research, Qin Feng finally found a way to crack it: "So that's how it is. As long as you touch these symbols in order, you can unlock the mechanism."

Following Qin Feng's instructions, everyone touched the symbols on the stone tablet in turn. The stone tablet made a slight sound, and then the floating key slowly fell down, as if waiting for their touch.

"Okay, you can take it now." Qin Feng said with a smile.

Zhang Meng learned his lesson this time. He carefully picked up the key and said excitedly, "We finally found the key! What should we do with it next?"

Qin Feng looked at the key with deep eyes: "I think the answer should be in this energy ball. This key may be the key to unlock the real secret of the energy ball."

"What are we waiting for? Let's go back and try!" Chu Tian said anxiously.

They quickly returned to the energy ball with the key. Qin Feng gently inserted the key into the groove at the bottom of the energy ball. In an instant, the energy ball burst into a dazzling light, and the entire space began to vibrate.

"Everyone be careful!" Qin Feng shouted.

The light gradually dimmed, and the energy ball slowly cracked, revealing what was inside... another puzzle.

"What? This is just the beginning?" Zhang Meng was stunned as he looked at the newly appeared complex device.

Qin Feng sighed softly and said with a smile: "It seems that the real mystery has just begun."
