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

While eating, Luo Fei did something in his mind—he concentrated his thoughts and silently recited "mark".

He marked Li Xiulan first.

He felt nothing special throughout the process; there was no light, no sound, and no external change. Yet, he knew in his mind that the marking was complete.

Next, he marked Luo Weidong, which was equally easy and smooth.

After marking it, he continued eating as if nothing had happened, without the slightest change in his expression.

Li Xiulan had no idea what her son had just done to her. She was peeling an egg with her head down, and broken eggshells were scattered all over the table.

As she peeled the egg, she muttered, "These eggs are so hard to peel, they keep sticking to the shell."

Luo Weidong pushed his egg over and said, "Eat mine, mine is easy to peel."

Li Xiulan glanced at it and noticed that there was a crack in his eggshell, making it easy to peel. She took it and started peeling it, while pushing her own egg, which had a sticky shell, to him.

Luo Weidong didn't mind at all. He took it and picked at it for a long time. Although the egg was pitted and uneven, he still finished it.

After finishing breakfast, Luo Fei stood up and suggested to his parents, "Dad, Mom, the weather is so nice today, let's go scuba diving. I've already asked the captain to choose a spot; the water there is so clear we can see fish swimming around."

Li Xiulan paused slightly, put down the bowl of porridge in her hand, and showed a look of both anticipation and nervousness on her face, as if she were a child playing in the river for the first time, feeling both excited and worried that the water was too deep.

"Diving? I can't do that. What if I choke on water?"

Luo Fei smiled and said, "I have professional equipment, and I'll be with you, so nothing will happen."

Luo Weidong scoffed from the side, "You're worrying too much. Xiao Fei has already made all the arrangements. Just go."

Li Xiulan glared at him, but said nothing more. She stood up and followed Luo Fei to the stern of the boat.

On the deck at the stern, the diving equipment was already neatly arranged.

Several diving suits were neatly laid out on the deck. Three of them were purchased by Luo Fei, while the rest were provided by the ship. These diving suits were all black, thick in texture, and resembled shark skin.

The equipment, including masks, snorkels, fins, and buoyancy control devices, was neatly arranged on the ground.

The captain and his crew were squatting on the ground, carefully inspecting the equipment: turning on the gas cylinder valves to listen for any leaks; checking if the pressure gauge needle was in the green zone; sorting the flippers by size; spraying anti-fog agent on the masks and wiping them clean with a soft cloth.

Luo Fei stepped forward, squatted down, picked up a diving suit, and handed it to Li Xiulan.

"Mom, please wear this first. It's a wetsuit, it keeps you warm."

Li Xiulan took the diving suit, reached out and touched it. The fabric was smooth and cool, and the touch was like touching a live fish.

"How am I supposed to put this on? Which end do I have to pull it on from?"

Luo Fei smiled, stood up, and helped his mother unfold the wetsuit. The wetsuit had a zipper at the back; to put it on, you had to first put it on your legs, then your upper body, and finally zip it up.

After Li Xiulan put on that black diving suit, it was as if she had been put into a black bag, with only her face and two hands sticking out.

She looked down at herself, then turned to look at Luo Weidong.

Luo Weidong was still unclothed and was standing to the side watching with great interest, a slight smile on his lips.

Li Xiulan glared at him and said, "What are you laughing at? You have to wear it too."

Luo Weidong's smile froze instantly.

Ah Jie and the others quickly helped their father put on his diving suit.

Luo Weidong was taller than Li Xiulan, and the wetsuit clung tightly to his body, making his stomach even more prominent.

Li Xiulan glanced at him and finally couldn't help but laugh out loud.

Luo Weidong blushed slightly and muttered, "What are you laughing at?" But when he looked down at himself, he realized it was indeed a bit funny. He smiled slightly, but quickly suppressed it.

Luo Fei handed the face mirror to his mother and taught her how to wear it.

"The mask needs to be adjusted to the right tightness. If it's too tight, it will cause a headache; if it's too loose, water will get in. After putting it on, take a breath through your nose, and the mask will stick to your face and won't fall off."

Following her son's instructions, Li Xiulan placed the mask on her face, took a breath, and the mask indeed stuck firmly. She released her grip, but the mask remained pressed against her face without falling off.

She exclaimed in surprise, "Wow, it really won't fall off!"

Luo Weidong also tried it out. His face was bigger than Li Xiulan's, and the mirror was a bit tight. He frowned and adjusted it several times before finally finding a comfortable position.

Then comes the breathing tube.

Luo Fei taught his parents how to bite down on the mouthpiece and how to breathe through their mouths instead of their noses.

"When underwater, the mask will cover your nose, so you can't breathe through your nose, you can only breathe through your mouth. Bite down on the mouthpiece and slowly and evenly inhale and exhale, don't rush or breathe forcefully."

Li Xiulan bit down on the breathing tube and tried it out, panting heavily.

Luo Fei smiled and said, "Mom, slow down, you don't need to use so much force."

Li Xiulan slowed down and gradually found her rhythm.

Luo Weidong learned faster than her, biting down on the breathing tube and breathing evenly.

Seeing that his parents were almost dressed, Luo Fei turned to Captain Sun and said, "I'm going to the restroom first. You guys stay here with my parents and help them get familiar with the equipment."

Captain Sun nodded and didn't ask any further questions.

Luo Fei walked to the bow of the ship and marked the position on the ground.

Then he raised his head, glanced at the sky, and his body instantly rose into the air, flying silently into the sky.

Xiao Lin was checking the gas cylinder when he caught a glimpse of Luo Feifei standing up. He paused for a moment, but didn't look up, and continued turning the valve.

Luo Fei, hovering several thousand meters above the yacht, took a coin out of his pocket.

He marked the coin with his mind, and then he threw it far away with force.

The coin moved extremely fast, making a muffled sound in the air and leaving an almost invisible white trail.

But in less than half a second, Luo Fei sensed that the mark on the coin had disappeared.

It is likely that during high-speed flight, the friction between the coin and the air generated high temperatures, instantly liquefying and decomposing the small coin.

Luo Fei hovered in the air, staring at the now empty trajectory, and remained silent for a second.

He asked in his mind, "System, is there anything that can withstand this speed?"

The system responded quickly.

The "portable water purifier" in the host's storage ring is made of materials capable of withstanding air friction at the host's current maximum speed. This item was designed for use in extreme environments, and its material strength far exceeds that of any metal currently available on Earth.

Luo Fei took the water purifier out of the ring. It was about the size of a palm, with a simple design, and felt cool to the touch; it didn't seem to be made of metal or plastic.

He weighed it in his hand; it was very light, almost weightless. With a thought, he marked the water purifier.

He then took a deep breath, held the water purifier in his right palm, and then flung it out.

The water purifier streaked across the sky at an extremely high speed.

Luo Fei watched the silver dot of light disappear into the distant horizon, but the marker remained in his mind.

He waited for ten seconds, then made a thought.

Teleportation.

One second he was high in the air above the yacht, the next he was dozens of kilometers away, in front of the water purifier.

The water purifier was flying toward him at a speed of tens of Mach.

He reached out and caught it precisely. He felt a force in his palm, but his body remained motionless, as if he had caught a leaf falling from a tree.

He glanced down at the water purifier in his hand; it was intact.

It was damaged, and there wasn't even a single scratch on the surface.

He looked up and around.

This is an unfamiliar sea area. There are no ships, no land, only blue sky and blue sea, and a white trail that was cut by the water purifier and is slowly fading away.

The distant horizon curves slightly, revealing the arc of the blue planet.

He stood in this vast, empty space, as if standing on the edge of the world.

Then he had another thought.

Back on the ship, at the bow, was the spot he had just marked.

His feet made no sound when they touched the deck, as if he had never left.

The sea breeze was still blowing, the waves were still crashing, and the parents were still at the stern of the boat learning how to use the diving equipment.

Luo Fei put the water purifier back into his ring, turned around and walked back to the stern of the ship.

Li Xiulan was squatting on the ground, her feet were covered with flippers, and she couldn't stand up no matter what she did. Like an overturned turtle, she tried to push herself up with her hands and kick her legs, but she still couldn't get up.

Luo Weidong stood aside, wanting to help but unsure where to start, looking somewhat helpless, his expression a mix of frustration and amusement.

Luo Fei walked over, squatted down, supported his mother's arm with one hand, and gently pulled her up.

The flippers dangled on her feet, making her walk like a clumsy duck, making a clattering sound.

She found her appearance quite amusing and couldn't help but laugh out loud, bending over with laughter and almost falling again. Luo Fei quickly reached out to support her.

Xiao Lin brought over the buoyancy control device and gas cylinder, and helped Li Xiulan carry them on her back.

The gas cylinder was heavy, and Li Xiulan's shoulders slumped slightly under its weight, but she quickly adjusted, straightened up, and held onto the regulator at her waist with both hands.

Luo Weidong also carried the gas cylinder. He was stronger than Li Xiulan, so the weight of the gas cylinder was nothing to him. However, he was not good at adjusting his posture, and the gas cylinder was tilted to one side. Xiao Lin had to correct it several times before it was straightened.

Luo Fei also put on a diving suit and carried an air tank.

He didn't need these things in the first place.

But I wore it anyway so as not to worry my parents.

Just as they were about to go into the water, a sound came from afar.

From several directions, large and small yachts, speedboats, and jet skis are approaching from different directions.

The first one was a medium-sized yacht with a white hull. Several people were standing on the deck, and some of them were holding cameras and taking pictures in this direction.

Several smaller boats followed behind, some fast and some slow, like beads scattered on the sea, strung together by an invisible thread, converging in the same direction.

Captain Sun glanced at the boats and said to Luo Fei, "Mr. Luo, this 'Blue Tears' reef is a famous diving spot nearby, and it's usually popular with tourists. Those boats are probably here to dive too."

Luo Fei followed his gaze and saw that the ships were getting closer and closer. He could see the figures on the decks. There were men and women, old and young. Some people were waving, and some were shouting something, but the sound was carried away by the sea breeze and could not be heard clearly.

Luo Fei didn't pay any attention.

This sea isn't his private property; anyone can come and go as they please.

He looked away, turned around, and faced his parents.

Li Xiulan was looking down at her flippers and didn't notice the boats.

Luo Weidong looked at the yachts in the distance and muttered to himself, "There are quite a lot of people."

Luo Fei said, "Mom, Dad, are you ready? Let's go into the water."
