A piercing whistling sound rumbled through the cave, and the sound of the whirring wind clearly came into the ears, and the rumbling thunder could not stop roaring.

"Click!" a blinding light entered the cave through the cracks in the boulders that covered the entrance.

Immediately after, the sound of raindrops resounded throughout the valley.

Lightning and thunder thundered in the sky, and raging storms poured down towards this wide valley. As if the end of the world is coming, everything will be crushed by the divine power of the world.

At this moment, all the students and lecturers are gathered in a very large cliff cave, there is dry firewood and hardwood prepared in advance, and the vigorous flames are licking the dry branches and leaves below, drawing a clear line with the cold and cruel world outside.

The students were resting against the cave wall, but lightning flashed through the cave from time to time, revealing frightened faces. When faced with the merciless abuse of nature, the final choice is to give in.

The faces of the three lecturers also gradually became solemn, listening to the sound of the water flowing outside the cave becoming clearer and clearer, they knew that there might be a lot of trouble today.

Mu Yi leaned on a corner of the cave wall, and behind him was Shangguan Qingwan, who was also staring intently outside.

Tonight's rainstorm seems a bit unusual, and although the wind and rain in the mountains often come without warning, it is still very rare to see such a violent storm.

The deafening thunder still rolled, not only showing no signs of abating, but also intensifying.

Mu Yi could even feel the slightest tremor of the cave wall behind him, and with the sound of thunder, debris was even falling from the top of the cave wall, raising one after another, making a group of students with ugly faces look up from time to time, probably worried that this cliff cave would suddenly collapse and bury them in it.

The rain became heavier and heavier, and through the cracks, you could even see the torrential rain pouring down into the low valley below.

At this time, Mu Yi suddenly thought of the huge sinkhole he saw a few days ago, where the river water was pouring down and how similar it was to the torrential rain that was pouring in the sky now.

"Boom!", a roar sounded outside, and even the ground of the cliff cave here trembled, and then there was a "boom!", and the sound of entering the water immediately sounded.

Mu Yi guessed that it should be a cliff rock outside that had been exposed to the wind and sun for many years and could not withstand the impact of the fierce rainstorm, and finally fell off and slid into the rushing river below.

The torrential rain was still falling, and there was no sign of stopping, and the sound of rushing water outside was getting louder and clearer.

At this time, Mu Yi, who was listening to the sound outside, frowned slightly.

The three lecturers on one side also stood up one after another, slowly walked in front of the students, and came to the back of the boulder that blocked the entrance to the cave.

The pale students in the back looked at the strange movements of the three lecturers, and the heart that was already hanging was pounding at this time, as if it was about to jump out of the chest.

The whole cave was silent, except for the sound of crackling fires burning through the wood.

Closer, closer, Mu Yi's left hand waved back, and his right hand gradually pressed on the scabbard at his waist.

"Bang!" There was a loud bang, like a muffled thunder explosion outside the cave, Mu Yi's pupils shrank, his cold hair stood upside down, and then he stood up.

There was a very bad premonition in my heart, feeling that this kind of danger was coming at me, this deep sense of crisis was indescribable, faintly rising from the bottom of Mu Yi's heart, becoming clearer and clearer.

A huge sense of oppression came to my face, and there was another "bang!" sound.

At this time, even the students who were slow to react finally reacted, and they all stood up and stared at the boulder at the entrance of the cave in disbelief.

The storm outside the cave was still continuing, and among the three lecturers in the cave, the lecturer surnamed He and the lecturer surnamed Meng had already shown the weapons in their hands, but the indifferent man standing in the middle still did not move, standing behind his back with his hands behind his back, just looking out of the cave with a deep gaze.

"Boom!" There was another loud bang, and the ground in the cave trembled, and then everyone saw that the boulder at the entrance of the cave seemed to have lost its support, and fell straight down.

The howling wind carried cold raindrops into the cave and easily extinguished the burning firewood.

"Get out of the way!" shouted the indifferent lecturer in the middle as the boulder fell.

The sound of thunder resounded throughout the cave, and everyone couldn't stop buzzing. Although they were in shock, when they heard the shouts of the indifferent lecturer, they immediately hid behind the protruding stones in the cave.

Although the movement was not slow, some people were still one step late, and they were drenched by the wind and rain that poured into the hole, and they were embarrassed.

Dragging Shangguan Qingwan, Mu Yi also dodged and hid behind a boulder behind.

The wind howled down the cave, and the raindrops followed. Seeing the three figures standing steadily at the entrance of the cave, they were all soaked.

But the three figures remained immovable, their feet as if they were rooted in the ground, and even the storm raging outside the cave could not shake the steps of the three of them.

came, and the piercing scream once again overwhelmed the wind and entered Mu Yi's ears. My heart sank, and what I was worried about finally came.

"Click!" The lecturer surnamed Meng on the left swung his knife and knocked away the giant arrow that came straight to the door, and then there was a crackling sound at the entrance of the cave.

Mu Yi's eyes could only see the brilliance that kept flashing in the hands of the lecturer surnamed Meng and the lecturer surnamed He, but the indifferent lecturer in the middle did not raise his hand in the slightest during this process.

However, something that surprised Mu Yi happened at this time. I saw a huge arrow with the thickness of an arm pass through the knife net of the two lecturers next to him, and came straight towards the indifferent lecturer in the middle.

However, the strangeness happened, and when the giant arrow reached a distance of less than a foot from the eyes of the indifferent lecturer, it seemed to be grabbed by the tail of the arrow from behind, and it was just suspended in front of the indifferent lecturer's eyes, unable to move forward at all.

Such a strange scene happened under Mu Yi's nose, looking at the giant arrow that then fell straight to the ground like a kite with a broken string, Mu Yi's brain boomed.

Thinking of it before, Mu Yi had personally sensed the cultivation of the indifferent lecturer, and the result also surprised Mu Yi, a lecturer with no cultivation appeared in front of Mu Yi's eyes like that.

I had doubts at the time, but it has never been confirmed, and along the way, Mu Yi has not had the opportunity to contact this indifferent lecturer, so he has not been able to solve the doubts in his heart.

But just now, that magical and weird scene completely shocked Mu Yi.

How could such a perverse thing happen in the world, and it happened right under his nose, Mu Yi couldn't figure it out, let alone figure out what the truth was.

But no matter what, it really happened, and it happened under Mu Yi's own witness.

Staring intently at the indifferent lecturer, Mu Yi almost forgot about his current situation, and wanted to witness the miracle happen again.

did not disappoint Mu Yi, the raindrop-like arrows outside the cave kept flying towards the entrance of the cave, densely packed, large and small, like moths to a fire, without hesitation, straight to the three figures standing at the entrance of the cave.

Then, a scene that surprised Mu Yi even more happened again, when the locust-like arrows came to the entrance of the cave, they seemed to encounter an invisible barrier, and they stopped their swift figures, and then crackled downward and fell to the ground.

This time, Mu Yi noticed that the indifferent lecturer in the middle had moved a small step backwards, although it was not obvious, but he didn't really notice it.

What kind of magical thing is this, Mu Yi believes that with his own means, as long as he is prepared to block these arrows, there should be no big problem, but the premise is that he must use his own weapons to do it, if he is barehanded, Mu Yi believes that he will definitely be shot into a hornet's nest.

But the indifferent lecturer standing in the middle did just that, and without even lifting a finger, he blocked the arrows from the sky.

Although he didn't know how the indifferent lecturer did it, Mu Yi also had a faint guess in his heart.

Eventually, the endless arrows stopped coming.

Outside the cave, the storm was still ravaging the fragile valley.

Mu Yi knew that the real danger had just come, the rain of arrows just now was just an appetizer, and the real feast was still hidden in the darkness behind.

The purpose of the previous rounds of arrow rain was only to consume the physical strength of the three lecturers, although they knew this, they could not choose to be three lecturers.

If you don't stop the rain of arrows, let the arrows in the sky shoot into the cliff hole behind, I don't know how many students will die. Even though the trainees were lucky enough to dodge the arrows, the cliff caves behind them could not.

As long as the powerful crossbow hits the cliff hole behind, the broken stone will also cause great casualties, because this cliff hole is only so big that the space is limited, and even if you want to dodge, there is no room to move. Moreover, in the long run, this cliff cave will not be able to escape the fate of collapse and collapse, and no one will be able to control the situation at that time.

Therefore, the three lecturers had to block the arrows, although they knew that it was a trap, but they had no choice, and the three lecturers had to jump without hesitation with their eyes open.

Gloomy black clouds still gathered above the valley, rushing and tumbling without a moment's pause, covering the peaks on either side of the valley and shrouding the entire valley in its gloomy blackness.

The storm also continued, and Mu Yi sometimes sighed, whether the heavy rain in the sky could be exhausted, it had lasted for so long, but the torrential rain like a waterfall was still swaying to the fullest, pouring into the valley below.

And the water in the valley is getting faster and faster. Along the slopes on both sides of the valley, the flood water rushes over the lush vegetation that stands on the slopes, splitting their heads and covering their faces, carrying away large slabs of loose earth and gravel from the slopes, and finally merging into the equally raging water in the middle of the valley.

The sound of rushing water became louder and louder, and Mu Yi's heart became more and more nervous.

"Click!" A bright lightning bolt streaked across the valley, and a beating shadow appeared in Mu Yi's eyes.
