Water

"Where are they?" Not long after, the iron cave door was pushed open from the outside, and a group of dark-complexioned men armed with various firearms filed in.

A bald leader walked in from outside and questioned the bearded man beside him.

"Boss, they crawled into the back of the cave!" the bearded man said in a very awkward tone, pointing his gun toward the corner of the wall, which was usually used as a latrine.

The surrounding atmosphere became suffocating in an instant. These armed guards were like cold-blooded killing machines; with a single order from the bald man, they could reduce this entire place to ashes with their bullets.

"Be careful. The missiles are all gone. If they've been piled up in a corner, they could be very dangerous!" the bald man warned, then waved his hand, signaling his men to move forward.

They slowly approached the back of the cave, their weapons aimed at their surroundings, ready to send anyone to their maker at the slightest sign of movement.

At this moment, the three people behind the cave had already quietly made their way up the stairs to the top of the mountain.

"Fang Bie," Tony called his name with some awkwardness, "is your portal protected?"

Fang Bie gave him a very confident look. "Of course. I surrounded them with stone blocks. When I have the resources later, I'm going to surround them with obsidian!"

Tony still had the heart to joke with them at a time like this. "No need. When we get out, I'll build you a big box out of titanium alloy and put your door inside it!"

"It's a deal. I'll be waiting for your titanium alloy box!" Fang Bie replied with a smile, then used the square stone block in his hand to plug the one-meter-wide passage behind them.

Unless the people in the cave took out rocket launchers to bombard the area, they could never harm the three people now hidden within the layers of rock.

Fang Bie could even hear the gunfire below, along with a hoarse, angry roar. He asked Tony, feeling a bit puzzled.

"What's wrong with them?"

A mysterious smile appeared on Tony's oily face. "I left them a little gift when I left."

"BOOM!" A massive roar erupted from the cave below, accompanied by the hysterical screams of people who seemed to have been injured.

"The effect seems pretty good?" Fang Bie raised an eyebrow.

"Of course," Tony was much more relaxed now than he was in the original story. "This is my specialty!"

"But isn't this a bit cruel?" Fang Bie, after all, was not someone who had walked through an era of war, and he suddenly felt a moment of hesitation.

"When you see what they've done to prisoners and civilians, you won't have such thoughts," Yinsen shook his head. "You don't want to know."

"Then..." Fang Bie felt a bit ridiculous for his sudden childish thought and changed the subject. "Can we start?"

"Thud!" Yinsen pulled a wooden door out of his backpack, placed it slowly on the ground, and then set down another one.

The space Fang Bie had temporarily dug out was not large, and after he placed the four doors, it became extremely cramped.

Tony also pulled an iron pickaxe from his backpack and opened a two-square-meter hole in several places within the cave, and the cave they had just come from was also opened up with a hole at this time.

"Let's do it!" the two said almost simultaneously, and a set of iron armor was donned over their bodies as they spoke.

Fang Bie had also put on a suit of iron armor early on, took out a bucket of water, and slowly poured it over their heads.

Then he took out another bucket of water and repeated the process over their heads. At the center where the two infinite water sources converged, a new water block immediately formed and began to spread in all directions.

Fang Bie didn't actually create a perpetual infinite water source here; this was just a large 3x3 space. Because of the extreme height, the water would continuously flow and wash downward until it filled every area below.

He performed a few simple operations, letting the water wash over their heads and pour into the cave through the isolated space created by the wooden doors!

"Boss! There's a cave here!" The bearded man suddenly discovered the cave that had appeared on the wall. Too busy to check on his subordinates who were injured by the explosion, he rushed over to claim credit.

Upon hearing the news, the bald man didn't hesitate; he walked over with his gun. "What cave? Let me see..."

The group gathered around the cave entrance, wanting to investigate the principle behind this strangely appearing cave.

A cave that appeared so abruptly before them, with such smooth cuts, clearly wasn't something normal. They gripped their weapons even tighter.

Just then, a rumbling sound startled them; the massive vibration woke them from their gawking.

"Earthquake! Earthquake!" Someone in the crowd shouted. The group of thugs, who had been so confident, suddenly panicked and began to roar in confusion.

"Rumble!" The massive sound approached from afar, but the vibration didn't increase, which actually made them relax their guard.

Having walked through life and death on the battlefield, how could they lose their nerve so easily?

They felt more and more that the sound was coming from inside the cave, so they leaned in closer. The rumbling sound, like the surging waves of a great river, became an inescapable noise in their minds.

"Whoosh!" A stream of water rushed toward their faces, washing away the dust that looked like it hadn't been cleaned in months.

Some of the gunmen even had looks of joy on their faces. "Water! Water!" they muttered, their tongues thick.

But the bald man, who had also been splashed in the face, had a grave expression! This wasn't an oasis filled with water sources; it was a desert where water shouldn't exist at all!

The water flow didn't slow down after the initial splash; instead, under the pressure of the great height, it became violent and surging!

In different worlds and at different heights, what should have been cold, lovely little things had now turned into lethal demons.

This was an opening a full cubic meter in size. When a column of water poured out from it, the smiles on the faces of these excited thugs instantly froze!

Especially after one man was washed against the wall by the current and immediately lost his strength as his life force faded, the excitement on their faces was finally replaced by a different kind of fear!

The water, which had only been soaking their ankles, gradually changed from that savior-like color into a demon that could devour their lives!

"BOOM!" An even larger surge of water poured down, pushing their bodies backward along the cave walls!

Everyone started running, because behind them, several more caves appeared on the ceiling, and a waterfall-like torrent surged forth, looking as if it were about to drown them all!

"Run!" The bald man was the first to react. After shouting this, he didn't care about the reaction of his subordinates and fled for his life!
