Now that he understands the mystery of this endless corridor, Lin Feng naturally has a corresponding way to crack it, I saw that after he took a short rest, he raised his steps again, but this time he was different from just now, just now he tried his best to hide his footsteps, lest he be discovered, and now after knowing that there was no one in this corridor, Lin Feng fell heavily to the ground with every step forward, and for a while, the entire corridor echoed continuously.

Looking at Lin Feng who was walking forward step by step, although Lin Li'er didn't understand the purpose of his strange move at this time, she still followed closely in line with the principle of unconditional trust in Lin Feng.

This time, Lin Feng's pace was slow, every time he landed, he would listen carefully for about two seconds, and then take another step forward, just like that, after a long journey again, Lin Li'er, who had been following silently, saw Lin Feng's figure suddenly stopped, and then he stood up straight, turned around, and made a silent gesture to Lin Li'er who was dazed.

didn't bother Lin Li'er anymore, Lin Feng slowly closed his eyes at this moment, raised his right foot high, and stomped down hard.

"Bang!"

A dull sound instantly echoed throughout the corridor, Lin Feng, who closed his eyes, listened carefully to the continuous echo, until the echo completely dissipated, Lin Feng opened his eyes, and then he quickly walked forward ten steps, stomped his foot again, and the deafening sound sounded again.

A huge echo rushed into her ears, and this time, Lin Li'er, who had been unknown, suddenly raised her head, her eyes were shining, and she looked at Lin Feng, and Lin Feng also smiled slightly after seeing Lin Li'er's expression, he knew that she had understood what she was doing.

So, Lin Feng walked back to Lin Li'er's side quickly, and said with a smile: "Building such a long corridor must be used to hide things, since it is to hide things, then there must be a room, the passages around this are solid walls, the room must be hollow walls, solid and hollow, there is still a little difference in echoes." ”

"Yes. ”

Lin Li'er nodded happily, every time Lin Feng achieved something, she would be happy from the bottom of her heart, even happier than her own achievements.

Looking at the bright smile on Lin Li'er's face, Lin Feng couldn't help but smile and touched her head, then turned around, looked at the walls on the left and right sides of where the two of them were standing, and said softly: "Okay, since we have found the right place, let's study how to get in."

"Hmm. ”

Lin Li'er nodded in response, and then the two separated, walked to the nearest wall to her, one left and one right, and studied it carefully.

After all, the scope of observation has been reduced to the minimum, and after a while, Lin Feng saw a small protrusion in the wall in front of him facing his right hand.

This small protrusion looked like a button, but it was too miniature to be the size of a fingernail, and it was exactly the same color as the wall, if it weren't for Lin Feng's careful observation, I am afraid that the two of them would never have seen it.

After studying for a while, Lin Feng didn't figure out what it was, so he raised his hand and wanted to touch it, but was stopped by Lin Li'er.

"What's wrong?"

Lin Feng asked suspiciously.

"We'd better not touch this weird button. ”

Lin Li'er swallowed her saliva, subconsciously looked up at the walls on both sides, and said with a scared expression.

"Hahaha, you were really bitten by a snake once, and you were afraid of the well rope for ten years. ”

Looking at Lin Li'er with a look of fear on her face, Lin Feng couldn't help laughing, but after laughing, Lin Feng's actions didn't continue, after all, he had already experienced this strange mechanism twice, who could say that this time it was not an organ that could kill people?

However, now that he finally discovered something, he couldn't just freeze, so Lin Feng's eyes rolled, he thought of a countermeasure, looked up and said to Lin Li'er: "Li'er, you go and stand where I stood just now, in that way, if something really happens, you can take me." ”

"Okay. ”

Lin Li'er looked at Lin Feng, although there was still a little worry in her eyes, but she finally nodded, stood up, and cautiously walked to the position where Lin Feng had just stood when he tested the echo.

Seeing Lin Li'er in place, Lin Feng also turned his head, and after a short exhale, he saw that his face was serious, his eyes were firmly fixed on the small button, and without too much hesitation, he directly raised his right hand and pressed it gently.

Pressing the button all the way down, Lin Feng withdrew his fingers, took two steps back, and looked at the wall in front of him, but nothing happened.

Seeing this scene, Lin Feng couldn't help but turn his head to look at Lin Li'er not far away with a puzzled face, and Lin Li'er could only reply to him with a confused expression, just as the two made eye contact, the next moment, the wall that had not moved just now suddenly began to tremble slightly without warning, making a dull sound.

Faced with such an abnormal situation, Lin Feng quickly ran backwards, until he ran in front of Lin Li'er, and then stared at the trembling wall with a look of great enemy.

Under the cautious gaze of the two, the wall trembled for a moment, and then began to slowly sink downward, the whole process did not last long, as the wall sank, the space behind the wall was revealed little by little.

It wasn't until the wall was completely sunk into the ground that Lin Feng tentatively took a step forward, and after finding that there was nothing unusual, he boldly came to the hole that had been exposed step by step, and looked inside, only to see that the space behind the wall was not large, and there was still nothing, Lin Feng couldn't help frowning when he saw this, this pretending to be a ghost for so long, why is there still nothing?

Just when Lin Feng was puzzled, Lin Li'er also came to his side, looked around at the empty small room, and after confirming that there was no obvious mechanism, she raised her feet and walked in.

Standing in the room, Lin Li'er glanced outside, and suddenly laughed, she nodded at Lin Feng and said, "I understand." ”

"Got what?"

Lin Feng asked suspiciously.

Regarding Lin Feng's question, Lin Li'er did not answer, but waved her hand at him, and said with a smile: "You will know when you come in." ”

"Well, listen to you. ”

Lin Feng shrugged his shoulders, did not hesitate any longer, walked directly into the room, and stood beside Lin Li'er, this time he did not ask again, but continued to look at her with questioning eyes.

"Look. ”

Lin Li'er triumphantly stretched out her finger and pointed forward.

Looking in the direction of Lin Li'er's finger, Lin Feng also suddenly realized, because he had already seen that next to the gate that was exposed because of the sinking of the wall, there was an LED screen printed, and the screen was lit up with a dark red light, displaying an Arabic numerals.

“-1”

"It turns out that this is an elevator. ”

Lin Feng looked up and looked around as he spoke, but in the end, he didn't check out anything suspicious, after all, judging from the fact that Fadro could build such a long circular corridor for defense, if he killed someone in the elevator, it would be a loss of identity for him.

However, although it was roughly determined that there was no danger in the elevator, Lin Feng did not dare to press the eye-catching arrow downward button under the LED screen, he didn't know where this elevator would lead, because the elevator he was in at this time was different from the elevator he usually took, except for the downward button in this elevator, there was nothing in this elevator that allowed him to choose the floor.

Looking at the hesitant Lin Feng, Lin Li'er said again: "Since we have arrived here, we can't go back anyway, we can only continue to walk." ”

Listening to Lin Li'er's words, Lin Feng couldn't help but turn his head to look at her in surprise, feeling Lin Feng's burning gaze, Lin Li'er couldn't help but lower her head and asked softly, "What's wrong?"

"Nothing. ”

Realizing his gaffe, Lin Feng smiled awkwardly, then turned his head away and said, "Li'er, you are different from before. ”

"Huh?

Lin Li'er raised her head, a flash of panic flashed in her eyes, she looked at Lin Feng, and hurriedly asked, "What's the difference?"

Looking at the slightly panicked look on Lin Li'er's face, Lin Feng couldn't help laughing, reached out and touched her cheek, and said in a long voice: "You are becoming more and more-"

"What's getting more and more?" asked Lin Li'er in an eager tone.

"It's getting more and more cute. ”

When the words fell, Lin Feng blew Lin Li'er's upturned nose at a lightning speed.

"Oops. ”

Lin Li'er, who felt that her nose was "attacked", instantly lowered her head, her face was blushing, a pair of pink little hands were twisted together, she stomped her feet slightly, and said softly: "Brother, you... You're so annoying. ”

"Hahaha. ”

Looking at Lin Li'er's shy appearance, Lin Feng laughed without any scruples, at this moment he was like an elder brother who watched his sister fall into the prank trap he set with his own hands, laughing unscrupulously and trembling all over.

In this way, the pleasant atmosphere lasted for a long time, until Lin Feng lost his strength to smile, and then gradually calmed down with the mood of the two people standing in the elevator.

"Whew. ”

Gently let out a sigh, although Lin Feng's mood was calm now, there was still a hint of obvious smile on the corner of his mouth, obviously, after this little episode, the mood he had been suppressing was also better.

Then, Lin Feng didn't stop at all, and walked directly to the only button, he turned his head to look at Lin Li'er behind him, and under her extremely determined gaze, he raised his right hand, stretched out his index finger, and gently pressed the button.

"Ding. ”

With a crisp and pleasant sound that came out of nowhere, the elevator began to slowly descend, although the elevator was very large, and the speed of descent was not slow, but Lin Feng and the two did not feel anything at all, not even a trace of shaking, as if the elevator was still stationary, I have to say, it is really good to have money.
