Fog Formula-Warning Book of Fog City Search Chief's Strange Talk

"Ocean snow?"

This is the first time Jian Shenxiu heard this term, he turned his eyes to Qihai Hegong who spoke suspiciously, waiting for his explanation.

"Ocean snow is an ecological phenomenon." The white-haired boy said hastily.

"Ecology believes that most of the energy sources of organisms on the earth come from the sun. The natural environment captures solar energy through the photosynthesis of plants, and these captured solar energy is passed along the food chain in the form of organic chemical energy to various species. life, and ultimately provide energy for the entire ecosystem. Therefore, green plants are the cornerstone of ecology, except for a few extreme cases, where there is life, there must be sunlight and green plants as energy sources.”

"Yeah." Jian Shenxiu nodded. This can be regarded as a basic biological theory. He is a science student, so he naturally understands it.

"However, unlike the land we live on, the water layer has a strong effect of isolating sunlight." Nanami Kazumi continued to explain patiently:

"On land, no matter how high a mountain is or how low a valley is, as long as the angle is right, there will always be sunlight. But in the ocean, it is different. Although the sun can reach a thousand meters below the water at its deepest, in fact the depth of the water At a water level of more than two hundred meters, the light is already very weak, and there are almost no green plants."

"So two hundred meters is a dividing line." Jian Shenxiu understood. "Below two hundred meters are deep-sea fish."

"Yes, this is a very important dividing line." Nanami Kazumiya nodded. "Because there are no green plants in the deep sea as food sources, and environmental factors such as water pressure, the deep sea ecology is significantly different from the diving ecology. For deep sea fish, although there are no green plants in the deep sea for them to obtain energy, they still have Marine snow serves as their food source. Ecologically, it is seen as the basis of deep-sea and benthic ecosystems."

"Details." Jian Shenxiu looked at him with interest.

"Marine snow, it's [snow], but it's not natural. It's protein detritus that settles from the upper ocean into the deep ocean."

Qihaihegong said seriously.

"Green plants can only grow in the upper light-transmitting sea area, but not all green plants in the ocean will be consumed by fish in the upper sea area. Green plant corpses that have not been eaten, food debris bitten off by upper-layer fish when they prey, The incompletely digested feces they excrete, these substances containing organic matter are suspended in the sea water, and gradually fall from the upper sea to the deep sea."

"This is a grand sedimentation. It may take weeks for a protein debris to sink from the sea surface to the bottom of the sea, but this kind of sedimentation continues in the ocean for 24 hours. They are suspended in the water layer like snowflakes. Floating like that, feeding the flourishing sea fish."

"That's why." Jian Shenxiu immediately understood what he meant, and his eyes lit up immediately.

"Although because of its high degree of variation, we cannot determine what water layer it lives in through its structure, but through its food, we can still determine the area where it lives."

"Yes." Nanami and Gong nodded affirmatively.

"No matter how it mutates, the food it eats must indicate the area it lives in. The creature that feeds mainly on marine snow must be a deep-sea fish. It must live in the water layer below two hundred meters!"

"The vicinity of Xuejianze is all offshore, and there are not many areas with a water depth of more than 200 meters... Immediately call out the charts around the east coast!"

Seeing that Shenxiu immediately turned his head to look at Markesias, his heartbeat accelerated suddenly, and he realized something instantly, and his voice immediately became louder.

This is quite important information. Qi Haihe Gong didn't know what this meant, but he knew it clearly after seeing Shenxiu. Because the place where the ship disappeared was on the side of Xuejian Zedong, and the road on the side of Xuejian Zedong was flat. Seeing that Shenxiu studied the sea chart today, and the far sea has been closed by fog, the only place on the east side where the water depth exceeds 200 meters is...

"yes."

Markesias also reacted, and immediately called up the sea chart on the east side from the tablet he carried with him.

The bluish fluorescent light suddenly lit up in the dark corridor, illuminating the faces of the four people. For a moment, everyone's eyes were focused on the tablet in the hooded boy's hand. The image on the screen clearly appeared in everyone's eyes, and Qihai and Gong immediately understood what Jian Shenxiu was excited about just now.

Because he also saw that in the middle of the flat continental shelf on the east side of Xuejian Ze, there was only one crack that seemed to cut the continental shelf open. On the entire east side, only here the water depth exceeds 200 meters.

"Xuejianze Hengduan Valley..."

Nanami Kazumiya finally remembered that there was still this place. He was so absorbed in his studies that he hardly heard anything about it on weekdays, so much so that he forgot that there was such a famous scenic spot in Xuejian Ze.

Before the eternal night falls, it is a well-known diving holy place.

"Is it the search and rescue team? I'm the search chief Jian Shenxiu."

Just when Qihai and Gong were still in Lengshen, Jian Shenxiu who was next to him had already started calling. He held the communicator with a stern voice, but from Qihaihegong's position, he could clearly see the joy on his face.

"Immediately change the scope of search and rescue, and change the main search and rescue area to around Hengduan Valley."

The chief inspector said decisively.

"At the same time increase the search depth and add the scope to underwater."

"Search and rescue underwater?" A man's surprised voice came from the communicator. "Mr. God, as far as I know, the lady didn't have a diving plan before she disappeared. Is this..."

"Do it now!"

However, Jian Shenxiu, who had caught the clue, didn't give him a chance to hesitate, and immediately made a final decision and hung up the phone. Then, without stopping, the communication was resumed immediately.

"Fanxing Technology? This is the search bureau. I want a batch of underwater detectors to explore the Hengduan Valley. How long will it take to prepare them? Three hours? Okay, I will send someone to pick them up in three hours."

"Is it the Diving Association? This is the Search Bureau. I need some divers who are familiar with the underwater terrain of Hengduan Valley..."

Seeing that Shenxiu was communicating with the other end of the communicator quickly, making phone calls one after another. He walked out while talking, and took his black coat from Marchesias.

"As you agree."

Finally, seeing that Shenxiu took time out during a phone call, and before he was about to walk out of the corridor, he patted Qihai and Gong on the shoulder, with hot eyes, Chen Ken said.

"See you on the coast at eight o'clock tomorrow morning,"

"..."

The white-haired boy looked at that gaze, and felt silent for a while. Seeing that Shenxiu had already arranged everything for the follow-up, he didn't refuse this posture at all.

"See Mr. God!"

However, just as Shenxiu was about to step out of the door, Qihai and Gong, who had been silent behind him, suddenly spoke up and stopped him.

"Um?"

See Shenxiu turn around.

"I want to remind you that the so-called [mutation core] we extracted is the [ocean snow] in the stomach of the evidence. That is, it is the ocean snow itself that feeds these deep-sea creatures that causes the evidence to mutate, and This marine snow is in the water layer...everywhere."

Nanami Kazumiya said seriously.

"..."

Seeing Shenxiu and hearing the words, his expression also changed.

"So, if everything works out as we infer."

The white-haired boy said in a low voice.

"Then the entire water layer may be very dangerous now."

"knew."

Seeing Shenxiu nodded, he went straight out.

"I will arrange for people to evacuate."
