Yang Mumu swam inside along the rocks near the shore.

The weather is very good today. There are not many waves on the beach and not many waves on the seabed. The undercurrents are much calmer and there are many schools of fish swimming leisurely under the water.

This was perfect timing, location and people for Yang Mumu, and she swam down easily.

When you see the fish or shrimp you like, don't think too much. Just take out the fishing tools you drew earlier in the space and start fishing.

A small net caught a lot of fish, which made Yang Mumu very happy, as she had a guaranteed dinner tonight.

Yang Mumu dug a small pond in the space with an idea, brought in sea mud and sand, and when he saw the seaweed on the seabed, he touched some seaweed and brought it into the pond.

Yang Mumu even took a special walk around the pond to find some edible kelp and put it into the small pond. Finally, he introduced seawater into the pond, and a small pond for breeding marine life was quickly created.

Seeing the empty pool, she simply put some reefs into it to enrich the aquatic environment in the small pool.

Finally, I put all the fish caught in the net into the shed. When I encountered fish and shrimp, I cast a few more nets so I wouldn’t have to worry about having no place to raise them.

It was Yang Mumu’s first time swimming under the sea and he found it very novel. With the light on his head, he could see the seabed clearly. Everything he saw was curious and he would pick up a piece of it and put it into his space.

As she swam along, she saw mantis shrimps lying under the rocks, big crabs with beautiful patterns, large scallops with their mouths open to breathe, and oysters bigger than her palm. All these things made Yang Mumu's eyes widen, and she hurriedly took the tools to get them.

She was also very observant and was able to find the mantis shrimps and crabs hiding under the mud and sand. She caught them accurately with every pinch. The more she caught, the happier she was. With the oxygen tank on her back, she completely forgot the main purpose of coming down and just went down to the sea to buy fish for free.

After catching half a bucket of shrimps and crabs and an extra-large king crab, Yang Mumu stopped reluctantly, suddenly remembering that he came down to go under the Moon Reef.

Yang Mumu put her things away and looked at the unfamiliar seabed around her. She couldn't tell the direction, so she simply surfaced to see where she was.

You don't know until you look. Once you look, you realize you have gone too far, in the opposite direction. You don't know how far away you are from your destination, but you can't see the reef anyway.

Yang Mumu slapped his forehead and smiled in annoyance. Oh, it’s a mistake to buy seafood for free.

She had no choice but to pack up her equipment, go ashore and walk back along the coastline to the place where she went into the sea.

After arriving at the location, she put on her equipment and went into the sea again. This time, she swam towards the reef in the middle. When she saw crabs and small fish along the way, she only grabbed those near her body and would never be tempted by them and chase after them.

This time she didn't go astray and she quickly swam to the Moon Reef.

Yang Mumu patted the reef, swam around it to check, but couldn't figure out what it was, so he swam downstream along the reef.

Like a dragon coiling around a pillar, it swam around the reef from top to bottom, checking every inch of the reef bit by bit, and touching different places on the reef with its hands to confirm whether there were any mechanisms.

It looks like it’s not far from the coastline, but the water is very deep. It can be said to be the deepest place in this area. You can’t see the bottom at a glance in the dim seabed.

The entire reef remains roughly crescent-shaped underwater and has been severely corroded by sea water, with a bumpy surface.

There were some small scallops and conchs on the reef. These were seafoods that were right before her mouth. She picked them up one by one when she saw them. She steamed the small scallops and spread them with minced garlic, which was crunchy and delicious. The conchs were also delicious when stir-fried.

After swimming to the bottom of the sea, his hands touched the mud and sand, but Yang Mumu still didn't find anything special about the stone, nor did he find any good treasures, nor did he see anything eye-catching.

For a moment, she was confused.

Is there really the golden finger that Lu Qianyao mentioned?

The only creatures on the reef were those that she had just caught and originally belonged to the seabed.

Lu Qianyao was so sure and had dreamed about it many times. Logically, there should be something underneath. Yang Mumu didn't believe it and continued looking.

She circled the reef once, twice, and three times, and finally found some clues at the bottom of the reef near the mud on the seabed. The cracks and lines were a bit special and did not seem to be naturally formed.

She used her hands to dig away the layers of mud and sand under the reef. After digging about ten centimeters, she saw an unusually protruding shape on the main body of the reef buried in the mud. It was also a small crescent shape, very similar to the reef that was exposed above the water, except that this one was only a semicircle as small as an egg.

Yang Mumu touched the protruding crescent reef curiously and saw a tiny gap between the small reef and the main reef. She pressed it, but there was no response.

For some unknown reason, she grabbed the small crescent-shaped reef and pulled it out with a little force.

It actually moved when he pulled it out. Yang Mumu used some more strength to pull it out. There was a clattering sound, which was the sound of the iron chain colliding when it was dragged out.

The small crescent-shaped reef turned out to be a handle, connected to a thick iron chain.

When it was about 20 centimeters long, there was resistance.

Yang Mumu exerted force again and dragged it again. With a click, what came out from the back was no longer an iron chain, but a square hole on the big reef.

She looked in front of her with some surprise. What was she seeing now? It was a chained drawer embedded in the big reef that she pulled open.

When the stone drawer was opened, seawater poured into it. It really was a drawer. The space inside was actually waterproof. The water could be isolated when it was closed, and the water would pour in when it was opened.

Is the siphon principle used for drainage?

As soon as Yang Mumu let go of the chain, it retracted and the drawer closed by itself. He had to keep the chain pulled.

She pulled and released the stone drawer with interest, playing with it for a while, then she put the chain in her hand and kept pulling it, and poked her head over the stone drawer to take a look.

There was also a rectangular iron box inside, which was very heavy.

Now that we are here, we must learn about this place thoroughly before leaving. If there is something missed, it will be a good thing for Lu Qianyao.

Yang Mumu put it into the space and also went into the space.

Considering that she had been searching for the things in her hand for a long time, she decided to take a look at what was in the box before doing anything else.

This iron box is easy to open. You just need to squeeze the lock to open it.

Yang Mumu opened the lid of the iron box with great anticipation, and as soon as she opened it, she could see everything inside.

When she saw the familiar things inside, she stared in shock, her mouth wide open, and looked completely stunned and shocked.

I threw the lid into my hand, touched the things inside, and couldn't believe it.

"What? Why is this thing in here?"
