Chapter 78 Oyster wind chimes
Due to the previous sea urchins, many shellfish—especially the snails and oysters that were abundant nearby lost their food and died in the sea. Therefore, there are many shells left by snails and oysters in this sea area.

The first day's inspection work was not much arranged, and the only two girls in the team were taken care of by the boys as a matter of course, and seemed to be a little free. They went to the sea to catch a lot of empty oyster shells, and started making oyster shells after dinner. wind chimes.

The materials needed include thin and flat driftwood picked up from the sea, fishing line, iron wire, and of course oyster shells.According to the principles of balance and aesthetics, drill five holes in the driftwood with an awl.Similarly, carefully drill a hole in the top and bottom of the oyster shell. Because the oyster shell is thin and brittle, one will break if you accidentally use too much force. The two girls wasted a lot of oyster shells and made 20 holes. of.

Due to the sharp edge of the shell, it is easy to be scratched under the wind shaking after directly piercing the shell with a thread. Therefore, the iron wire is first wound into a loop and passed through the holes on the oyster and driftwood, and then connected with a fishing line.In this way, a beautiful oyster wind chime is completed.With the help of the boys, the wind chimes were hung under the eaves of the boat house.

"Ding, found the ownership of the one-star item, congratulations to the host."

The perennially dumb system actually spoke today.

[Oyster Wind Chimes: The oyster shells sleeping in this sea, with ancient thoughts, are made into wind chimes, which bring good luck, increase luck by 15%, and increase the cooling effect of wind by 20%. 】

In the evening, I had a good rest, and when it was dark, Professor Yang made intensive arrangements for the tidal flat observation activities at night.

Late is the time when sea fish are active, so observation at night is very necessary.

A high-power detection spotlight is mounted high, creating an aperture with a radius of about one meter on the sea surface.Li Chengxin, Xiao Jia and Professor Yang held fishing nets at the edge of the aperture, waiting for the arrival of phototactic fish.

Sure enough, not long after, several small fish swam over, one was transparent with a light blue shadow; there were other strange-looking juvenile fish of unknown origin.After waiting for a while, a medium-sized fish came chasing the small fish.

Seeing that the timing was about right, Professor Yang told Li Chengxin and Xiao Jia to spread out their fishing nets and start catching fish from the shore.The students who controlled the spotlights also followed them, controlling the scope of the spotlights in front of the fishing net, and there were students on both sides holding net bags to prevent the fish from slipping away from the side.There are also students holding underwater cameras to take images of sea fish swarming in front of the fishing nets, which are used as additional records, in case any fish run away, they can also be identified from the images.

Wait until all the fish in the fishing net are taken out and placed in the aquarium to remove all kinds of small fish, such as mackerel, squid and jellyfish in the fishing net.

"It's really a bit rare..." Professor Yang muttered, a little disappointed.After all, Li Chengxin's coastal management has just begun, and it seems that he has to continue to work hard.

All the fish were documented and the students released them into the ocean.

"Grow up well!" Girls are always sentimental and reluctant to let go of the fish they caught.

Early the next morning, when Li Chengxin woke up, he felt a burst of coolness. He guessed that this was probably the cooling effect provided by the wind chimes that were hung last night.

But if it were Professor Yang, he would definitely answer this question in a more scientific way.Evaporation of water absorbs heat, and the beach can absorb water. When the water in the beach evaporates, the heat is taken away, and the sand will continue to absorb water from the seawater, continue to evaporate and absorb heat, thereby reducing the surrounding temperature.

Of course, Li Chengxin knew that Professor Yang was right, but Professor Yang had only been here for the first day, and Li Chengxin, who had been here all year round, could feel the temperature change more clearly.While chatting with Professor Yang, several students who had gone to catch the sea in the early morning came back laughing and joking.

One of the students held a large salmon about half a meter long in his hand: "Professor! We have extra meals!"

Several other students also came up and chatted about the origin of the salmon. When they rushed to the sea, they found a salmon stranded in a puddle on the rocky beach.

Professor Yang thought about it for a while: "July is indeed the time for salmon to migrate, but there is no river suitable for salmon to migrate near this coast? It's so strange. This fish is probably stupid. Since it bumped into it, it must be eaten. It's gone!"

Li Chengxin turned his head and glanced thoughtfully at the oyster wind chimes under the eaves. The 15% luck bonus did not expect to be effective so soon.

The salmon was cleaned and ready to be eaten for lunch, but before the meal, the students had to build a model of Li Chengxin's experimental coast.

Before they came, Xiao Jia had already contacted Li Chengxin and got the size of the experimental coast.Students have custom-built a scaled-down version of a water feature box.

First, use special clay to make the basic terrain drawn yesterday, then place sand and a few representative large rocks on the terrain, and then pour in clean water.Soon, a coast familiar to Li Chengxin appeared in the water box.

Several boys used chopsticks to make models of bamboo fences, mussel floats, and artificial beach sandboxes.Finally, seeing that there were still materials left, I simply made a small model of the floating platform of the sea urchin breeding cage and placed it at the end of the water feature box.The girl with ingenuity made a simple model of a houseboat, which is not so simple to say the least. Li Chengxin noticed that the doors and windows of the houseboat model can be moved, and there is a small sampan that can be taken out under the houseboat .

These small models and some ready-made tree models are fixed in the water feature box, recreating the scene of this coast.In addition, several students made some small waterproof labels. One side of the label is a photo of the marine creature they found, and the other side is the name and introduction of the creature.Insert these tags on the model relative to where they found the creature.

"Looking at it this way, we've actually found quite a few creatures!" Li Chengxin exclaimed.

"It's not enough!" Professor Yang didn't take Li Chengxin's exclamation seriously.

At this time, a student who was secretly playing with his mobile phone seemed to find something interesting in the mobile phone, and quietly poked the classmate around him to let him look at his mobile phone screen.The classmate glanced at the screen of the mobile phone and laughed uncontrollably, which attracted everyone's attention, so the mobile phone was publicly shared by everyone.

After finally reaching Professor Yang's hands, Li Chengxin couldn't wait to lean over to have a look.On the screen of the mobile phone was displayed the layout plan of the coastal plan drawn by Li Chengxin himself a few months ago. The level of painting on it was so appalling that even Professor Yang laughed when he saw it.
