The giant grouper from last time was one and a half meters long and weighed over two hundred and twenty jin.

The green grouper he had encountered today was slightly smaller, but it was still around one and a half meters and definitely weighed over one hundred and fifty jin.

Chu Mingcheng looked at the speargun in his hand and didn't rush forward to attract the grouper's attention.

These large groupers were fierce. If you dared to get close, it would dare to bite you.

So Chu Mingcheng swam back to the surface, found Jiang Luoluo, and swapped out his speargun.

"Did you find a big fish?"

"Yeah, a big green grouper. I'm afraid the carbon fiber speargun won't have enough power, so I came back for the wooden one."

"Then get on the boat first, I'll take you over there! It'll be easier for me to help you pull the fish up later too."

"Alright."

Chu Mingcheng climbed onto the boat, and Jiang Luoluo drove him to the area where he had spotted the green grouper.

He re-entered the water and was just about to load the wooden speargun when he heard a splash behind him.

He turned his head to see that Jiang Luoluo had followed him in.

She shook the camera in her hand and smiled. "I have to record a spectacular scene like this."

"Then equalize your ears first, and don't dive too deep later." The green grouper was near the coral at a depth of thirty meters. Chu Mingcheng was not comfortable letting her follow him that deep.

So he let go of his speargun and first taught her the Frenzel maneuver for equalizing.

Jiang Luoluo, of course, wouldn't push herself. She practiced the Frenzel maneuver a bit. Although she wasn't very skilled, as long as she didn't dive too deep, she would be fine.

After she was ready, Chu Mingcheng loaded the speargun, then took her hand and started to swim down into the water.

When they reached a depth of ten meters, he turned to check on Jiang Luoluo's condition.

Seeing that she was fine, he continued to lead her down to fifteen meters.

The dive watch displayed the depth and breath-hold time. Chu Mingcheng let go of her hand, signaling for her to stay at this depth and not go any deeper.

Jiang Luoluo was very obedient. She could feel the pressure of the water from all directions.

Moreover, this depth was right on the edge of neutral buoyancy in the water column. With her weight belt, she could float steadily at this level.

If she went any deeper, she would be affected by negative buoyancy. Then her body would start to sink, and she would have to kick her legs to maintain buoyancy, which would consume her oxygen faster and force her to return to the surface sooner.

Feeling that Jiang Luoluo was fine, Chu Mingcheng raised his speargun and quickly swam to a position above the green grouper.

He didn't hesitate. After aiming, he pulled the trigger, and the spear shot out with a "whoosh!", burying itself almost completely into the grouper's body.

The green grouper thrashed wildly in pain. Chu Mingcheng let it struggle and didn't immediately reel it in.

He held the speargun, let out the line, and then headed for the surface.

He acted so decisively because he was worried Jiang Luoluo couldn't hold her breath but would insist on filming the whole process of him hunting the grouper, which could easily cause her to choke on water.

More than forty seconds had already passed. Her breath-hold time was unlikely to exceed a minute and a half.

So he let out the line as he swam over to her, took her hand, and began to slowly ascend to the surface.

He didn't swim fast, giving Jiang Luoluo a chance to adapt to the changing water pressure.

In reality, a depth of fifteen meters didn't require such caution, but this was his future wife; he couldn't be too careful.

Back on the surface, Jiang Luoluo spat out her snorkel and took a breath. "I almost ran out of air! Looks like I really need to practice holding my breath."

"Yeah, when we have time, we should go swimming. Long-distance swimming can improve your physical fitness and lung capacity. Oh, and you need to keep practicing the Frenzel maneuver; otherwise, you won't be able to dive into deep water."

As Chu Mingcheng offered his advice, a new idea sparked in his mind.

But for now, he needed to reel in the fish. He would discuss it with Chen Yang and the others after he was done.

The green grouper's vitality was astonishingly strong. Even though it was hit in a vital spot, it still struggled for a long time before Chu Mingcheng managed to pull it to the surface.

The grouper was estimated to weigh over one hundred and fifty jin. He and Jiang Luoluo couldn't get it onto the boat by themselves.

In the end, they had to call Chen Yang and Zhang Wei back. It took all four of them working together to finally haul the fish aboard.

"Another huge grouper! Are we in the wrong spot or something? How come we're only catching small fish?" Zhang Wei said, his face full of envy.

He reached out and slapped the fish's body, making a thudding sound.

"Our spot is probably shallower, but it's not bad. We've caught plenty of these valuable groupers," Chen Yang said, holding up his stringer with several valuable groupers on it. He was quite satisfied with his catch for the day.

"Looks like you guys had a good morning too!" Chu Mingcheng did a quick mental calculation and found that Chen Yang's catch for the morning was already worth five or six thousand yuan.

This was just the first morning. If they added the afternoon and evening, the two of them could probably make back at least a quarter of their costs, and if they were lucky, maybe even a third.

"Still can't compare to you. This one green grouper of yours is worth close to ten thousand!" Zhang Wei sighed.

Chen Yang was more philosophical about it. "We were never comparable in the first place. Don't be fooled by the fact that Ah Cheng's diving certification is the same as ours; his diving skills are on a completely different level. The deeper you go, the higher the chance of encountering big fish. We can only dive to about twenty meters right now. How many big fish can we possibly run into?"

"Ah Cheng is a monster!" Zhang Wei thought about how Chu Mingcheng could hold his breath for at least five minutes while actively swimming, and he was filled with envy.

His own dynamic breath-hold was just barely over two minutes; he had almost failed his certification test.

Chu Mingcheng just smiled at this, not getting cocky. After all, he was cheating with a system.

But since everyone was here, he brought up the idea he'd had earlier. "What do you guys think about us partnering up to open a swimming pool? Later, when our freediving certifications are higher, we can turn it into a freediving club."

Hearing this, everyone began to seriously consider Chu Mingcheng's proposal.

Jiang Luoluo thought that Chu Mingcheng was probably suggesting opening a swimming pool for the sake of her underwater dance videos.

Zhang Wei, for some reason, had a mischievous smile on his face, as if he had thought of something fun.

Only Chen Yang considered it most seriously. He pondered for a moment and said, "Opening a club is different from opening a swimming pool. The venue requirements are very different."

"To be honest, I'm not that interested in opening a swimming pool, but partnering on a club sounds pretty interesting."

Chu Mingcheng looked at Chen Yang. "You think opening a club is a good idea?"

Chen Yang nodded. "It's doable, but right now, I think only you could reach instructor level in a short time. Ah Wei and I still have a long way to go. Plus, we'd need to constantly bring in new partners to strengthen our team. It all sounds pretty complicated."

"There's no rush, we can take it slow. We have a boat anyway, and our main focus will be on sea fishing and spearfishing. The club can be a side business."

"After all, once our freediving skills reach a certain level, opening a club will be a natural next step."

The club was a spur-of-the-moment idea for Chu Mingcheng. He brought it up while they were resting, with no intention of starting it immediately.

He was just thinking that Jiang Luoluo would need a venue for her future underwater dance videos.

And if they were going to get a venue, they might as well open a club to avoid having the space sit empty most of the time, which would be a waste.

After resting for a while, Chu Mingcheng and the others split up again to hunt, not returning to the Sky until lunchtime.

The crew would tag and sort their catch, placing it in the refrigerated hold, so they didn't have to worry too much about it.

After showering and having lunch, they decided not to go spearfishing in the afternoon. Instead, they each went back to their rooms to rest, preparing for some deep-sea night fishing.

He took a short nap and woke up at only two in the afternoon.

The sun was at its strongest at this time, and Chu Mingcheng had no intention of going fishing.

Lying in bed for a while got boring, so he got up and went over to Jiang Luoluo's room.

No need to knock, he just used his key to open the door.

Jiang Luoluo hadn't felt particularly tired that morning. After a short nap, she was leaning against the headboard, preparing to research underwater dancing.

But before she could even open her laptop, her room door was opened.

She wasn't startled, though, because besides Chu Mingcheng, no one else could open this door.

"You're awake?"

"Yeah, I was a little bored, so I came over to see you."

"Then help me research underwater dancing. I have no idea where to start." Jiang Luoluo scooted over on the bed, motioning for him to come up.

Chu Mingcheng closed the door, naturally took off his shoes, and squeezed onto the bed.

The computer was already on. Jiang Luoluo leaned against his chest, opened Bilibili, and searched for underwater dance.

There wasn't a lot of material on the subject, but they could still find some good videos.

"Hey, there really are classical-style underwater dances!" Jiang Luoluo said in surprise.

She clicked on a video, and the very first one blew them away.

The dance itself wasn't particularly outstanding, but combined with the underwater cinematography and post-production editing that sped up some movements to match the beat of the music, the entire dance was elevated to a new level.

And you could do things in the water that were impossible on land, which was another advantage.

"Wait, how can she hold her breath for so long?" Jiang Luoluo asked curiously after watching the video.
