I started by watching videos, and I chose 10,000 combat power.

Luo Fei stopped.

He floated in the water, gazing at the scene thirty meters away, his fingers twitching slightly involuntarily.

The woman was struggling in the water, kicking and thrashing her arms and legs like a fish caught in a net.

The instructor held her down, preventing her from surfacing or turning around, keeping her pressed to the bottom of the sea. Her mask was removed, her snorkel came off, and she choked on several mouthfuls of water, coughing violently, her body beginning to convulse.

The coach waited a few seconds, then helped her put the mask back on, cleared the water out of the mask, and put the breathing tube back into her mouth.

The woman was gasping for breath, bubbles gushing violently from her breathing tube, and she was curled up in a ball as if she were crying.

Luo Fei knew exactly what was going on.

He had seen similar videos on short video platforms—some diving instructors would deliberately create dangerous situations, such as turning off tourists' air tanks, removing tourists' masks, or holding tourists underwater to prevent them from surfacing.

They exploit tourists' fears to demand exorbitant tips, sell expensive "souvenirs," or lure them into signing up for even more expensive "advanced courses."

Tourists often dare not speak up because they are in the water and the instructors are professionals. Even if something happens, it is difficult to provide evidence to clarify the situation. Moreover, most people do not want to cause trouble, so they choose to pay money to avoid trouble and swallow their anger.

Luo Fei withdrew his gaze and continued swimming forward. He didn't bother with that other matter.

The woman is safe now; although she was frightened, her life is not in danger.

The coach didn't really want to kill her; he just wanted to scare her so she would be willing to pay.

He came to accompany his parents diving, not to become an underwater policeman.

He swam back to his parents, where Li Xiulan was filming a group of bright yellow fish. The fish gathered together, like a moving sunflower, swimming over her head. She tilted her head back, holding her phone high, like a little girl chasing after a celebrity.

Unbeknownst to Luo Fei, the yellow diving suit was watching him the moment he looked away.

The coach calmed the woman down and had her sit down to rest on a rock on the seabed. Then he floated to the surface, removed his snorkel, took out his cell phone from his waterproof bag, and dialed a number.

"Old Liu, which district are you in?"

His voice was low, with the excitement of a hunter spotting his prey.

The voice on the other end of the phone was somewhat muffled, but it was clearly a man's rough voice: "Sector Three, what's wrong?"

"Come to section seven. There's a group of people: two older people and three younger people. The older people look like beginners, and the three younger people are two men and one woman. The woman has a good figure, but the movements of these three young people don't seem like those of an instructor."

"They taught those two elderly people the most basic things, such as kicking and buoyancy control. Even a beginner who just got their Open Water certification wouldn't be taught these things so sloppily. They were just a few ordinary people who knew how to dive, probably with their families."

There was a two-second silence on the other end of the phone, then the gruff voice rang out again, tinged with a meaningful laugh: "A fat sheep?"

"Fat sheep, I've been observing them since this morning."

The man in the yellow diving suit said, "They look well-off. These kinds of family groups are the easiest targets. With an elderly person present, the younger ones won't dare to act rashly, and they don't have much experience underwater, so they don't know how to handle it. We'll do it the old way. Afterwards, they won't call the police; they'll obediently hand over the money."

The laughter on the other end of the phone grew even louder.

"Okay, I'll tell Lao Zhao, and the three of us will go together."

The person in the yellow diving suit hung up the phone, put their snorkel back on, and submerged in the water.

He swam back to the woman, patted her on the shoulder, gave her a thumbs-up, and pointed ahead, indicating that he should continue forward.

The woman was still in shock and breathing rapidly, but she dared not disobey and had no choice but to obediently swim forward with him.

Meanwhile, Luo Fei was accompanying his mother as they swam across a coral reef.

Li Xiulan's attention was completely drawn to a blue fish. She held up her phone and chased after it to take pictures, completely unaware that trouble was approaching.

Luo Weidong followed behind her, also holding up his phone, taking pictures of Li Xiulan chasing fish from behind.

As he patted himself, he started laughing, and bubbles gurgled out of his breathing tube.

Xiao Lin and A-Jie stood guard on either side of them.

Kobayashi had a diving knife tucked behind his waist; the black handle was hidden under the buoyancy control device and was almost invisible unless you looked closely.

Her eyes were scanning the surrounding sea, not looking at the fish, but keeping an eye on the people around her.

She was the first to notice the anomaly.

After disappearing from the edge of Zone 7, the yellow diving suit reappeared in the direction of Zone 4. And there were not just one person, but three people—three yellow diving suits, with red labels on their air tanks, making them particularly conspicuous in the water.

They scattered in different directions, but their swimming trajectories all pointed towards the location of Luo Fei and the others.

Kobayashi frowned behind the mask, his fingers unconsciously touching the hilt of the diving knife at his waist.

She kicked her flippers twice, moved closer to Luo Fei, and patted him on the shoulder.

Luo Fei turned his head.

Xiaolin pointed in those three directions, then pointed to his own eyes, and then to the three yellow figures.

Luo Fei looked in the direction she was pointing and saw three people in yellow diving suits approaching at a leisurely pace, seemingly diving normally.

He looked away, shook his head slightly at Xiaolin, and waved his hand.

Kobayashi removed his hand from the hilt of the knife, but his body remained alert.

Li Xiulan was completely unaware of this.

She was squatting next to a rock on the seabed, taking pictures of a sea hare with her phone.

The sea hare was very small, only the size of a thumb, with a pink body covered in white down, and two tentacles that stood upright like rabbit ears, swaying gently in the water.

She held her phone very close, almost touching the sea hare, and the image on the screen was shaky, making it impossible to get a clear picture.

Three yellow wetsuits approached.

The nearest one stopped a few meters away and held up a tablet that was in a waterproof bag.

The tablet displayed an image that read: "Professional diving instructors, one-on-one teaching, 500 yuan a day, guaranteed to teach you."

The person holding the tablet was wearing a black mask, obscuring their face, but the corners of their mouth below the breathing tube were slightly upturned.

The person in the yellow wetsuit on the left was also holding up a tablet that read: "Professional underwater photography, 250 yuan a day, professionally retouched photos, video included."

Luo Fei looked at the two tablets and let out a sneer.

Bubbles were rising in strings from the breathing tube at the corner of his mouth.

500 a day, guaranteed to teach you?

I'm afraid that once people accept this, a day will become an hour, five hundred will become five thousand, and the "church" will become a "church abolition."

He had seen this kind of tactic too many times online—first, they would offer a low price to lure people in, then once they were in the water, they would turn off the gas cylinders, remove their masks, create panic, and then demand a higher price, refusing to take them up unless they paid.

When you're underwater, your life is in someone else's hands. How could you refuse? He shook his head at the three men in yellow diving suits. The gesture wasn't big, but the meaning was clear—no need, please leave.

Then he turned around and swam towards his parents, no longer looking at them.

The three coaches exchanged glances. Though they couldn't see each other's eyes through the mirrors, they had worked together for a long time, and a nod or a gesture was enough to convey their meaning. The one closest to them put away his whiteboard and gestured to the other two—his index and middle fingers together, pointing in Luo Fei's direction, then he made a fist with his thumb pointing upwards. This was their internal code, meaning "Follow along, proceed according to plan."

The three of them kicked their flippers at the same time, following Luo Fei and his group at a leisurely pace, maintaining a distance of about fifteen meters, waiting for their opportunity.

Ah Jie also spotted them.

He swam to Luo Weidong's left, a little behind Xiaolin, and could clearly see the three yellow figures.

He removed his hands from the buoyancy control device, lowered his body slightly, and adjusted his posture to put himself in an angle where it would be easier to exert force.

His expression behind the mirror was unclear, but his eyes were fixed on the three shadows without blinking.

Xiao Lin swam to Li Xiulan's right, forming a protective stance with A-Jie on either side. The distance between them was just right, allowing them to see each other's gestures without being too cramped.

Luo Fei led his parents to continue swimming into the deeper water.

He didn't speed up, maintaining a pace that his parents could keep up with, as if the three people behind him didn't exist at all.

After chasing the sea hare, Li Xiulan started chasing a blue fish. The fish swam very fast, and she gave up after chasing it for a few meters, turning around and swimming towards Luo Fei.

He couldn't speak because he had a breathing tube in his mouth, but his eyes behind the mask curved into two crescent moons, and he smiled like a child.

Luo Weidong followed behind her, his flippers kicking steadily. His air tank was still more than half full, enough for another hour of diving.

The three coaches followed for about five minutes. Seeing that Luo Fei ignored them, neither speeding up nor turning around, they realized what was going on.

They've seen this kind of reaction many times—tourists with elderly people and children are afraid to cause trouble, don't want to have conflicts, and will avoid them if they can, and endure them if they can.

This type of person is the easiest to get.

They sped up, their fins kicking the water more frequently, and their speed doubled, quickly closing the distance to about five meters.

Luo Fei sensed it.

He didn't turn around.

He kicked his flippers, increasing his speed considerably, but he didn't shake them off—he was deliberately speeding up to see what these three were up to.

Li Xiulan sensed that her son was going faster and assumed he was going to see something interesting, so she excitedly followed. Her flippers kicked much harder than usual, and the bubbles she kicked up left a long white trail behind her.

Luo Weidong followed. He was in better physical condition than Li Xiulan and didn't feel tired, but he was a little puzzled—why was Xiao Fei swimming so fast all of a sudden?
