Douluo Continent: Dragon Shadow Rebirth

"I say... do you think we opened something that we shouldn't have opened?" Zhang Meng stared at the device in front of him that was flashing with complex lights. His eyes were full of suspicion and his tone was full of his usual "wise man demeanor".

Qin Feng covered his forehead and said helplessly: "Don't say that as if you didn't want to open it before. You kept shouting that you wanted to 'punch it'."

"Who knew this thing actually hides something even more troublesome!" Zhang Meng scratched his head while looking at the complex mechanism that seemed to come from the future. "It really feels like something that tests my IQ... Besides, this kind of thing is not very friendly to me."

"IQ test?" Chu Tian couldn't help laughing. "You know this thing is not friendly to you? I thought you and it were natural enemies."

Zhang Meng replied angrily: "Shut up! I'm the only one here who dares to pick up the 'mysterious key'."

"You make it sound like you are so noble holding a key." Ye Li shook her head helplessly, "Isn't this thing just a broken key? Now it seems that it is not a simple thing at all."

Qin Feng also stared at the complicated device, frowned and said: "Indeed, this is not just a simple unlocking, but it seems to have solved a more complicated puzzle. I'm afraid we need to crack its core mechanism."

Zhang Meng immediately took two steps back and raised his hands high: "I give up! This kind of high IQ challenge is for those of you with good brains. I will be responsible for applauding."

"Look at how cowardly you are." Chu Tian smiled and patted his shoulder, "You really are worthy of being the 'muscle man' of our team."

Qin Feng looked at the two bickering clowns and shook his head helplessly, but he quickly returned to the point: "This mechanism is very complicated. It seems to be composed of different parts, and each part affects each other. We have to figure out the functions of these parts first."

"It sounds a bit like a puzzle." Ye Li narrowed her eyes and carefully looked at the flashing symbols and geometric shapes on the mechanism.

"That's right." Qin Feng nodded, "Each part may represent the arrangement of a certain symbol. We must find the correct combination."

"Combination?" When Zhang Meng heard this, his eyes turned and a smile suddenly appeared on the corner of his mouth. His expression seemed to be full of some kind of confidence.

Ye Li keenly caught the change in his expression: "Wait, are you up to something?"

Zhang Meng looked very proud: "Hehe, it's not a bad idea, it's just that I suddenly had an idea and thought of a brilliant solution."

"Tell me about it?" Chu Tian came over with anticipation on his face.

Zhang Meng waved his hands generously, his tone extremely serious: "Since this is a puzzle, we can try to take it apart! Great force can make miracles happen!"

"puff--"

Ye Li almost choked on her own saliva: "Do you want the entire underground hall to collapse directly?"

"Yes, your strategy of using great force to create miracles almost got us teleported to some unknown place last time!" Chu Tian couldn't help but complain.

Qin Feng smiled and shook his head: "Don't use brute force this time. If this mechanism is destroyed, the consequences may be more serious than the previous illusion."

Zhang Meng shrugged his shoulders, showing a helpless expression: "Okay, I just said it casually. So how do you solve it?"

Qin Feng then studied the structure of the mechanism carefully. He found that each symbol on the mechanism corresponded to a button, and these buttons seemed to be able to rotate, and each rotation would trigger a different reaction.

"Interesting..." Qin Feng said to himself, "This mechanism seems to be testing our memory and logical thinking. The symbol represented by each button may be some kind of ancient language."

Ye Li also came over: "Look here, the order in which these symbols are arranged may be the key. Each row has a certain symmetry."

"Wow, this sounds so complicated!" Zhang Meng looked at the symbols in confusion. "So, we have to decode these symbols first?"

"That's right." Qin Feng replied, "We need to arrange these symbols in the correct order to crack the entire mechanism."

"What are we waiting for? Let's start!" Chu Tian said as he rubbed his hands together, as if preparing for the upcoming challenge.

Qin Feng nodded and began to rotate the button step by step according to the logic of the arrangement of the symbols. Every time the button was turned, the symbols on the mechanism would change slightly. With the correct arrangement of each set of symbols, the entire mechanism seemed to be gradually unlocked.

But soon, trouble followed - as Qin Feng progressed in unlocking the system, low humming sounds began to be heard in the air, and the entire underground hall seemed to be shaking slowly.

"Oh my! Why is it shaking again?" Zhang Meng looked around in horror. "Every time you mess with these things, there's a loud noise!"

Ye Li glanced at him unhappily: "Aren't you used to it yet? Every time you activate the mechanism, there will definitely be some side effects."

Qin Feng also frowned and looked around, clearly sensing the uneasy atmosphere: "We need to speed up the process. The vibration of the mechanism means that it has begun to protect itself."

"I can't let you down this time." Chu Tian clenched the weapon in his hand and looked around vigilantly, fearing any sudden danger.

However, just as Qin Feng was about to complete the last set of symbols, an unexpected situation occurred. The entire mechanism suddenly emitted a strong light, followed by a sharp buzzing sound, as if resisting their cracking.

"Oh no, it's not going to explode, is it?" Zhang Meng shouted.

"Get out of the way!" Ye Li shouted.

However, the light and buzzing did not cause an explosion, but spread rapidly, instantly enveloping the four of them in a white light. Then, they felt their feet lighten, as if the entire space began to distort...

"Where are we going this time? Is this another illusion?" Before Zhang Meng could finish his complaint, the scene in front of him had completely changed.

The white light gradually dissipated, and they appeared in a completely different space.

"Where is this?" Chu Tian rubbed his eyes and looked around.

They were standing in an empty hall, surrounded by towering stone pillars. The ground was engraved with the mysterious symbols they had seen on the energy balls and mechanisms before. At the end of the hall, a huge black crystal ball was suspended.

“This won’t be another new puzzle…” Zhang Meng said with a look of despair.

Qin Feng smiled bitterly and shook his head: "It is very likely."

"I knew that this kind of place would never let us leave quietly." Ye Li sighed helplessly.

"Well, now that we are here, we have to keep moving forward." Qin Feng said calmly, "It seems that this crystal ball may be the real core of our adventure."

"I don't care. I'll just follow you." Zhang Meng hung his head and gave up thinking completely.

They walked towards the black crystal ball suspended in the air. The surface of the crystal ball was flickering with strange light, as if it contained some powerful power.

"Everyone be careful." Qin Feng reminded in a low voice.

However, just as they approached the crystal ball, a deep voice suddenly came from all around, as if it came from some ancient existence: "You, are finally here..."

Zhang Meng instantly became alert: "Who? Who's talking?"

The voice in the air carried a mysterious power and continued, "Your arrival marks the beginning of the trial. Only the true brave can solve the final puzzle."

"Trial? Another trial?" Ye Li frowned. "We have passed so many trials. Do we need another one?"

"It seems that this is the final challenge." Qin Feng looked at the black crystal ball with a serious look, "This time, it may be our last chance to solve the whole puzzle."

"Then what are we waiting for?" Zhang Meng said with determination, "Now that we have come this far, let's fight it out!"

"That's right." Qin Feng nodded and said, "No matter how many challenges lie ahead, we have to face them."

As they approached the crystal ball step by step, the mysterious force in the air seemed to be calling them. The real puzzle was finally revealed before them, and their adventure was about to reach its climax.
