After diving nearly 500 meters down to 1,800 meters, the water pressure became extremely high, and Lu Yuan felt that he was having some difficulty breathing.

The equipment behind me kept making creaking noises, and some parts even pressed against my body, causing some pain.

There's no other way; we have to keep enduring what we have to endure, otherwise all our efforts will be in vain.

Lu Yuan gritted his teeth and continued to dive down, the beam of his flashlight constantly searching for something. Suddenly, he sensed something underwater flashing a strange red light.

The red light flashed and disappeared in an instant, causing Lu Yuan's heart to leap wildly.

Then he quickly glanced towards the underwater area, and suddenly heard a ripple from the water. He then received Shi Quan's voice in his earpiece.

"Lu Yuan, watch out underwater! It looks like something's coming!"

Lu Yuan dared not be careless. He held the flashlight tightly and shone it downwards, but the light moved very slowly underwater. It took him several seconds to be able to see things about two hundred meters away.

The red light flashed and disappeared again, and this time it was absolutely certain that the thing was a monster, and a very large one at that.

Because when the two red lights were flashing at different locations, he sensed that the other party was definitely more than two thousand meters away from him.

Now Lu Yuan would have to dive to a depth of nearly four thousand meters to reach the other party's underground location, and the other party's eyes could actually transmit signals several thousand meters away.

This indicates that the other party is extremely large, and the red light in his eyes is definitely very bright.

Lu Yuan cautiously continued to descend, as the ripples in the water grew louder and louder.

He seemed to feel his body swaying uncontrollably to the left and right as he swung his feet.

"Damn it, I have to make some preparations!"

Because humans are born on land, they have a strong sense of security with solid ground and high mountains.

But there wasn't even a single water plant nearby. Lu Yuan felt like he was in an abyss, with nothing in any direction—front, back, left, right, up, or down—that could give him a sense of security.

At this moment, he was isolated and helpless, alone in water thousands of meters deep, facing unknown fears. One can imagine how much pressure he was under.

Just then, Xiaoshan's voice came through the earpiece.

"Honey, let's come back. I'm too scared to let you go down there. Let's think of another way, okay?"

Lu Yuan couldn't answer; he continued to stare ahead.

Suddenly, a red light flashed by again, but this time it was brighter than before, and it seemed to be very close to him.

Just then, Lu Yuan suddenly sensed that a piece of land seemed to appear in the light below.

Upon seeing this land, Lu Yuan felt a surge of excitement. Once he reached that place, he was confident he could eliminate his opponent once again.

However, as Lu Yuan continued to swim downwards, the red light got closer and closer to him.

Finally, Lu Yuan was able to feel the intense pressure emanating from that monster, which was even more threatening than the dragon.

Dragons, at least, don't harbor hostility without reason, while the giant beast in the distance, with its red eyes flashing, seemed ready to devour any opponent it spotted, indiscriminately.

Lu Yuan hurriedly took out his weapon from the workshop space, but he dared not fire it casually.

If the other party isn't there to attack me, the moment I pull the trigger, if they're agitated, they'll definitely cause me a lot of trouble.

He had no intention of fighting this fifth- or sixth-tier, or even higher-tier, mutated beast underwater.

The gun in his hand gave Lu Yuan a lot of sense of security, but that was all.

At that moment, the light flashed again, and Lu Yuan could sense that the monster was about two or three hundred meters away from him.

The opponent is definitely very large, perhaps even larger than a dragon.

Holding the flashlight, Lu Yuan shone it on the monster and quickly adjusted the flashlight to diffuse the beam so he could see a larger area.

However, when the flashlight beam reached the other side, Lu Yuan realized that the monster was less than a hundred meters away. The monster suddenly opened its mouth wide, and the surrounding water flowed like a pump, constantly sucking the water into its mouth.

Lu Yuan felt his body moving out of his control, rushing wildly toward the other person's mouth.

"Damn it! I was careless again!"

Lu Yuan swam downwards with all his might, but he felt that no matter how hard he tried, he could not move his legs. The moment the other creature opened its mouth, the nearby algae, various plankton, and some small fish were instantly sucked into its mouth.

Because Lu Yuan was quite far away, he did not reach the other side and still had some time to escape.

However, the other party's mouth really opened like a bottomless pit. In an instant, countless amounts of seawater nearby were sucked in, but it was still possible to feel that a whirlpool had appeared around us, sucking everything into it.

At that moment, Lu Yuan's heart sank. He was really worried that he might be sucked in by the other party and never be able to survive. If that happened, it would be terrible.

Fortunately, the other party shut its mouth at this time, and then its body swam to other places.

Lu Yuan then noticed that his flashlight had slipped from his hand the instant the other person opened their mouth, and the spot where the light had been was swimming towards the underwater area.
