The sky was gray at this time and it began to drizzle. Fortunately, Meng Fei was wearing a windbreaker so he didn't get wet.

Looking up at the sky around him, he saw that it was all gray. It was obvious that it would not stop in a short time. Meng Fei thought for a moment and decided to continue on his way. The sooner he found Qing Linghua, the more hope Qiu Bo's mother would have.

Because of the rain, the already steep and difficult to climb Baigu Peak became even more slippery and muddy.

Meng Fei climbed towards the top of the mountain according to the planned route, taking one deep step and one shallow step, and his speed was much slower than before.

After walking for four hours, Meng Fei felt exhausted, so he found a big rock to sit on and took out a piece of chocolate from his backpack to replenish his strength.

As for water, Meng Fei didn't bring any with him when he came. As he had been working in the mountains with his grandfather since he was a child, he naturally knew how to find drinkable water outdoors.

After resting for a while, Meng Fei opened the satellite map to check his location.

The map showed that Meng Fei was at an altitude of 480 meters, very close to the 500-meter altitude warning line mentioned by the middle-aged man.

Meng Fei looked around, broke off a branch, shook it in his hand, and when he felt it was about right, he continued to move up the mountain.

After reaching an altitude of 500 meters, just as the middle-aged man said, ice holes of various sizes began to appear on the hillside. At first, it was okay, each only about half a meter deep, but as the altitude increased, the ice holes began to get deeper and deeper, and became more and more hidden, and were firmly covered by a layer of moss.

Meng Fei dared not let go of the long stick in his hand. He kept poking the road in front of him with the stick as he walked, for fear that he would accidentally fall into an ice hole.

This also slowed down Meng Fei's progress.

“Roar~~~”

Suddenly, a roar came from a distance. The sound was extremely sharp and harsh, but mixed with a sense of turbidity and heaviness, as if it was the sound effect amplified by a loudspeaker.

Meng Fei frowned slightly, he quickly pulled out the short blade from his waist, and held it tightly together with the stick in his hand, looking around vigilantly. However, after a moment of waiting, the biological radar carried by Meng Fei did not detect any creature approaching him.

He breathed a sigh of relief, but remained highly alert and continued cautiously toward the top of the mountain.

However, before he could take a few steps away, the roar just now sounded again! This time the sound was louder than before, and seemed to be closer.

Meng Fei's heart tightened and he stopped, listening attentively to the movements around him. The air was filled with a tense atmosphere and every slight sound made his heart beat faster.

He couldn't help but start to doubt his own judgment. Was there something wrong with the radar? Or was there something that could evade radar detection?

Meng Fei took a deep breath, calmed himself, and decided to speed up his pace to reach an altitude of 1,000 meters as soon as possible.

At the same time, he secretly prayed that he would not encounter any dangerous existence. As his pace quickened, Meng Fei's heartbeat became more and more intense, and the mysterious roar was always following him, constantly echoing in his ears...

“Roar~~~”

This time Meng Fei heard it very clearly.

The sound was near him!

And no more than five meters!

But Meng Fei's biological radar still did not respond!

Meng Fei's already frowned brows furrowed even more tightly, and he glanced around sharply, ready to deal with any danger that might come at any time.

But within a five-meter radius of Meng Fei, there was nothing else except a towering ancient tree. Meng Fei stared at the ancient tree, and the short blade in his hand unconsciously tightened a little.

Suddenly, the voice rang again, less than one meter away from Meng Fei's right foot.

Meng Fei was startled and subconsciously took a small step to the left.

Sudden!

Meng Fei felt his feet go soft, as if he stepped on a sponge. Meng Fei lost his balance instantly, followed by a strong sense of weightlessness, and the whole person began to fall.

Meng Fei was shocked and quickly reached out to grab any life-saving straw in front of him.

Finally, with Meng Fei's unremitting efforts, he grabbed a branch and stopped falling.

Meng Fei's heart was about to jump out of his chest at this time. He held on to the tree roots tightly with both hands. It took him a long time to calm down. Only then did Meng Fei have time to check the situation around him.

At this time, Meng Fei was in the middle of an ice hole. Below him was a bottomless ice hole, and above him was at least five meters from the ground. There was permafrost all around, with icicles and hoarfrost hanging on it.

Meng Fei took a deep breath and planned to take out the footrests from his backpack and climb out of the ice hole. He carefully loosened one hand, removed the strap on the right side of the backpack, and then switched to the left side.

However, just when everything was going smoothly as Meng Fei had expected, perhaps because Meng Fei's movements were too large, the tree root he was holding suddenly made a small cracking sound.

Meng Fei was shocked and immediately stopped all actions, not daring to move.

But things often go against one's wishes. The tree roots made breaking sounds again. Meng Fei looked up and saw that the surface of the tree roots was slowly breaking, just like a hemp rope burning in flames, breaking from the outside to the inside.

Meng Fei made a prompt decision and swung towards the wall of the cave. The short blade in his hand lit up and he stabbed it hard into the wall.

However, a short blade alone could not bear Meng Fei's weight.

The next second, Meng Fei fell towards the bottom of the cave again.

Meng Fei only felt that his body was constantly being hit, so he made a quick decision and curled himself up tightly into a ball to minimize the damage caused by the impact.

However, it was futile. Under the continuous strong impact, Meng Fei's eyes turned black and he fainted.

Fortunately, when he was about to reach the bottom of the cave, the originally vertical ice hole began to tilt. Meng Fei slid along the smooth ice surface for an unknown distance and finally stopped.

Meng Fei was in a terrible condition at the moment. He was covered in blood, as if he had just been fished out of a pool of blood. His face was horrible, covered with heart-wrenching bruises.

The most eye-catching thing is the terrible wound on his left hand. The wound cut deeply through the palm, as if it was going to tear the entire palm apart. Through the hideous wound, the metacarpal bones inside can be clearly seen.

Blood continued to flow out of the wound, dyeing the surrounding water red, but Meng Fei seemed unaware of it and still lay quietly on the ground, motionless.

At this moment, in the dark corner of the cave, a pair of green eyes suddenly lit up, shining with a cold light, and slowly approached Meng Fei.
