Seeing that Tian Fei disappeared into the gap in the blink of an eye, Lin Cheng hurriedly rushed to the gap and looked inside, but was once again obscured by the gray scene inside.

Seeing that he couldn't observe anything with his eyes, Lin Cheng could only give up observation, and instead pricked up his ears against the stone gate, ready to listen to whether there would be any movement inside.

After listening carefully, Lin Cheng really heard a few movements.

Under Lin Cheng's superhuman hearing, almost all of Tian Fei's jumping sounds behind the stone gate were collected by Lin Cheng, and because the space behind the stone gate seemed to be too empty, even if Tian Fei transformed into a very small mouse, jumping left and right, there were even bursts of echoes, which made Lin Cheng can't help but pinch a cold sweat in his heart.

However, since he didn't know how big the space behind the stone gate was, Lin Cheng finally couldn't hear any sound after listening carefully for about ten minutes, presumably Tian Fei had already gone deep into the cave at this time.

"How's it going, can you still hear it?"

Due to the limitations of their strength, Ling Sheng and Ling Meng could not use their hearing to grasp the situation inside like Lin Cheng, and at this time, seeing Lin Cheng retract his ears that were clinging to the stone door, he hurriedly asked.

Shaking his head, Lin Cheng, whose heartstrings had been tense for more than ten minutes, took out a cigarette and lit it, took a deep breath, and said, "If nothing else, Tian Fei should have gone deep into it, and even I can't hear any more sounds......

"This ......"

Hearing this, Ling Sheng's expression was full of worry, on the one hand, he was worried about what accident Tian Fei encountered, and on the other hand, he was worried about whether Tian Fei would be able to get back useful things.

Finding that his father's face was worried, Ling Meng could only comfort him: "Don't worry Dad, although Tian Fei's combat effectiveness is average, he is also a latent veteran, and this time he has transformed into a mouse, presumably the monster inside will not be as knowledgeable as him even if he sees him, so don't think too much." ”

"Rats?"

Hearing Ling Meng's words of comfort to Ling Sheng, Lin Cheng was a little noncommittal, he didn't know what the monster inside looked like, but since he was inside this strange rune stone door, these people or things would never be as simple as the two of them thought!

"Boom ——!!!"

Just thinking about his thoughts alone, Lin Cheng suddenly felt a shock on the ground, and then he heard an earth-shattering sound suddenly coming from behind the stone gate!

"What's going on?!"

Not only Lin Cheng, but Ling Sheng and the others were also shocked by this inexplicable vibration, and hurriedly grabbed the stone wall on the side to stand firm, and then saw Lin Cheng's brows suddenly wrinkled, and he quickly rushed to the stone gate as soon as he stepped on it!

"Roar——!!!

As soon as he rushed to the stone gate, before Lin Cheng could look inside, he heard a familiar beast roar that was even louder suddenly came from inside the stone gate!

"It's over!"

Hearing this beast roar, Lin Cheng's heart suddenly sank, combined with the earthquake at this time, he could think with his ass that Tian Fei was definitely discovered!

"Hair ...... What happened? Isn't it Tian Fei—"

At the same time that Lin Cheng rushed to the stone gate, Ling Meng and Ling Sheng also rushed over, at this time, seeing Lin Cheng's face was surprisingly ugly, Ling Meng's heart also sank, even she could guess what was going on.

"You two don't talk yet!"

With a wave of his hand, he interrupted Ling Sheng, who wanted to speak, Lin Cheng opened his eyes and looked into the gap, only to find that the inside of the stone gate at this time was no longer the gray scene he had seen before, and the gray mist that lingered in it had already been dispersed by the previous vibration, and what caught his eyes was not the endless ground he imagined, but a bottomless abyss with strange rocks!

"How can this be ......"

Finally saw the scene inside, Lin Cheng at this time was already stunned, according to the movement he heard before, he had already determined that it should be an incomparably wide ground hollow inside, but he didn't expect that there was no place to set foot in it at all, once he entered it, he would fall directly into that bottomless abyss!

And Ling Sheng also saw the scene inside clearly at this time, his expression at this time was even more unbearable than Lin Cheng, after all, the gap between what he imagined and what he saw was too big, which made him very suspicious that he had something wrong with his brain.

Lin Cheng, who frowned tightly, and had no idea what had happened inside, could only stare closely at the abyss inside, trying to see some clues from the endless darkness.

"You...... You say, could the violent shaking just now have something to do with this bottomless abyss? ”

While Lin Cheng and Ling Sheng were frowning and meditating, Ling Meng on the side suddenly spoke.

Hearing this, Lin Cheng's eyebrows suddenly raised, and after a few seconds of recollection, he slapped his thigh sharply and said, "Yes!" Maybe our previous guess was not wrong, and it is very likely that this abyss has only just been revealed, and it may have been covered by the ground we imagined until then? ”

"Huh?"

Hearing Lin Cheng's words, Ling Sheng also clapped his palms, "It's really possible!" But...... Why didn't the ground sink when Ling Meng opened this gap before, and it had to wait until Tian Fei went in before it suddenly sank? ”

"This can only be known when Tian Fei comes out!"

Waving his hand, after Ling Meng's reminder, Lin Cheng, who finally figured out the key points, finally breathed a sigh of relief, after all, doubting life This mood affects the fighting spirit too much, after solving this mystery, Lin Cheng can finally sort out Tian Fei's affairs again.

"But...... The ground has sunken, is that guy Tian Fei still alive? ”

Hearing Lin Cheng suddenly mention Tian Fei, Ling Sheng's mood that had just relaxed suddenly came up again, "This abyss can't even see the end of you and me, with Tian Fei's strength, how can he ......?"

"I said, you must have forgotten what Tian Fei's ability is, right?"

Without waiting for Ling Sheng to finish speaking, Lin Cheng directly waved his hand to interrupt him, "That guy is a shapeshifter!" He can turn into a mouse and dive into it, and naturally he can turn into a bird and fly out of this bottomless abyss! ”

"Oh...... Yeah! ”

Hearing Lin Cheng's reminder, Ling Sheng woke up like a dream, after the previous shock, at this time, he already felt more and more confused in his brain, and even forgot that Tian Fei was a person with transformation ability who could fly to the sky.

"Your dad is probably tired, you take him to the side to rest for a while, I'll watch here."

After noticing Ling Sheng's abnormality, Lin Cheng frowned slightly, but he didn't say anything, just waved his hand at Ling Meng, motioning for her to take Ling Sheng aside to slow down and speak.
