The next day, which was the last day Zhang Zi'an stayed in the small town by the sea, he drove to Carl's aquarium as usual.

"Hi! Jeff! Good morning!"

Water quality test expert Paul is testing something, his eyes are close to the eyepiece of the microscope. When he heard the sound of the store door opening and closing automatically, he glanced at him casually and just glanced at him. The distance from his eyes may be less than 1 cm away from the eyepiece.

He always has endless work to do. He has to measure the specific gravity of water once a week, the levels of nitrate and phosphate once a week, and the levels of ammonia and nitrite every two weeks. If abnormalities are found, they must be adjusted in time to determine whether there is a problem with the aquarium ecological chain or a equipment failure, otherwise a fish will suffer a lot of losses.

There are so many aquariums in the aquarium, he has to check in batches and randomly, and especially to record the inspection dates of each aquarium in detail. The work is very heavy, and of course, the salary Carl gave him is probably quite considerable.

"Good morning, Paul!"

Zhang Zi'an put down the plastic storage box with great effort and glanced at the store, "Where is Carl? Are you not here?"

"It should be at the back, you go find him." Paul straightened his body and recorded the data he had just observed on the computer. At this time, he noticed that the plastic storage box that Zhang Zi'an was holding was very heavy, and it seemed to be filled with boxes of water. He kindly asked, "Do you want me to help you?"

"No need, I'll do it myself, thank you." Zhang Zi'an looked at Paul's typical thin body shape, and probably he would have to help him.

At this moment, Carl came out from behind with a plastic bucket.

"Jeff, are you going to go back to Berlin today?" he asked.

"Yes, I'll set out in a while. Thank you for your care these days." Zhang Zi'an threw the villa key to Carl.

Paul was surprised, "What? I'm leaving now?"

"Yes, otherwise I won't be able to catch up with the closing ceremony of the film festival." Zhang Zian smiled and said, "Thank you, Paul, I learned a lot from you."

"That's how..." Paul lowered his head regretfully.

After several days of getting along, he became good friends with Zhang Zi'an because he found that Zhang Zi'an was easy to learn and could chat with him. This was a sense of recognition he could not get from Carl or others, because others were more concerned about the win or loss of the local team's game and whether they could advance to the Bundesliga next season, and had no sense of complex water quality records and monitoring.

"It's okay, keep in touch online. I will come over to play when I have time in the future." Zhang Zian hugged him and said goodbye.

"Jeff, you must come and take a look with me if you have something!" Carl waved to Zhang Zi'an impatiently.

"Oh? What?"

His mysterious appearance aroused Zhang Zian's curiosity.

"You'll know when you come here and take a look, while it's still alive..." Karl took him to the backstage staff area of ​​the aquarium, where there was a separate aquarium.

"Look, I haven't seen this thing before?" Carl pointed to the aquarium.

Zhang Zian walked closer and observed carefully.

There was only a layer of bottom sand in the aquarium. A strange creature was lying weakly on the bottom sand, covered with a hard chitin shell, like a combination of cicada monkey and pixie shrimp, but its size was hundreds of times larger than the two.

The cicada monkey, which is the juvenile body of a cicada, is named because it can climb a tree and transform into a cicada. The process is like a monkey climbing a tree, so it is named.

The shell of this creature is lilac and about one foot long. It lies on the bottom sand and looks like it is dead. If it weren't for its two tentacles still moving slightly, Zhang Zian really thought it was dead.

Between its body and the bottom sand, several pairs of appendages can be vaguely seen, and each appendage has sharp claws.

"Is this... the king's worm?" Zhang Zian asked uncertainly.

"That's right!" Carl's eyebrows were filled with excitement and regret, and he sighed, "It's a pity that it's almost dead. We may be the last two people it has ever seen."

"Is this certain? After all, it is a deep-sea animal and is used to the huge pressure on the seabed. Not to mention coming to land, even in shallow seas, it will die due to loss of pressure. It is not easy to last until now." Zhang Zian knew the fate of death faced by this rare creature.

The king's worms usually live on the seabed hundreds of meters underwater. They are almost impossible to keep as pets for ordinary people and are difficult to catch.

They can be seen occasionally in the deep-sea aquarium in Fuso. The people of Fuso also have an unusual love for this creature. The figures, dolls, key chains and the like in the shape of a king are selling well, probably because they think this creature is cute.

"Yes," Carl nodded, "so I'm anxious to ask you to come and see it for a last look. The living king-like worm is rare to see. When it dies, I will ask someone to make it into a specimen and place it at the door of the store."

"Where did it come from?" Zhang Zi'an asked, "Did the fishermen catch it?"

Carl shook his head, "It's strange. Does this look amazing when my friend picked up while walking by the beach yesterday? This kind of creature living in the deep sea knows that he will die if he floats on the surface of the Shanghai area, but it violates their survival instinct, as if he is anxious to go somewhere. My friend also knows that the creature of the Dow deep water lice in Fusang is not valuable, but it's strange to appear on the German seashore. Later, he looked carefully and recognized it as the king's worm, so he called me to notify me and I drove it back."

Zhang Zi'an knew that this was probably a strange phenomenon caused by the appearance of the mermaid.

"By the way, I'll give you a gift."

He motioned Carl to go back to the outside room with him.

"What? Don't tell me it's a Berlin Bear Doll. I'm too old to be suitable for that kind of gift." Carl said half-jokingly, "I have a signature photo of Feimas."

Zhang Zian also smiled, uncovered the lid of the storage box, pointed to the creature in the water and said, "It's this."

Carl was stunned when he saw the giant sea scale worm, and could not believe his eyes.

"My God! This...is this a giant sea scale worm?" he said tremblingly, "You brought it with the storage box?"

"Because there is nothing else available." Zhang Zian was helpless, "You can't buy an aquarium to store this thing."

Carl is indeed a person who knows the goods. He knows all kinds of strange creatures and recognizes the identity of the giant sea scale worm at a glance, knowing that this is a newly discovered species by scientists.

He looked around the storage box like a treasure. If he hadn't known the danger of this creature, he really wanted to hold it in his hand.

In contrast, the rarity of the King's worm is far behind.

Paul heard the two of them talking and came from the water quality test bench. He was also shocked when he saw this strange-looking rare creature.

"Is this giant sea scale worm a gift for me?" Carl suddenly recalled, "You want to give it to me? You should know how rare this creature is, right? There is probably no aquarium in the world that has them!"

"Yes, to thank you and Reina for taking care of me, and you like such creatures very much, don't you?" Zhang Zi'an smiled, "We Chinese people pay attention to courtesy and exchanges. I cannot be taken care of by you for nothing, otherwise it will make people laugh."

He changed his tone and said half-jokingly: "Besides, why did I bring this guy back to China? I'm afraid I'll be stopped by the customs? I'll inevitably have to spend more time talking, and maybe there will be trouble."

"But...how did you get this giant sea scale worm?" Carl asked in surprise, "As far as I know, they live in Antarctica, right?"

"I don't know how it came to Germany thousands of miles away. It's a coincidence that I picked it up while walking by the beach yesterday." Zhang Zian shrugged, "It's probably similar to what your friend had experienced, but I'm lucky. The living waters of giant sea scale worms are not that deep, and they won't die when they get ashore."

Carl thanked repeatedly and immediately urged Paul to free up the best aquarium in the store, arrange cooling equipment, simulate the water quality of the Antarctic waters in the aquarium, and be sure to entertain the new guest with the best conditions.

He is very confident that using this giant sea scale worm as a sign will definitely attract more customers to come to watch.

According to his experience, rare pets do not necessarily have to be sold. In fact, it may be better to leave them in the store as display and can promote the sales of peripheral products.

To a certain extent, Zhang Zian also felt the same way, because some customers who came to his store came for the rare chocolate Abyssinian cat, but in the end they met other types of cats, or bought imported cat food and cat supplies...

Taking advantage of this opportunity, he explained his ideas and hoped that Carl could help him introduce a batch of high-quality German aquarium equipment.

Carl has always been a major customer of local aquarium equipment manufacturers. He can get the equipment at a discounted price. He agreed to ask Zhang Zian to rest assured and would arrange for mail to China immediately.

After explaining the matter, Zhang Zi'an bid farewell to them, started the car, and embarked on the way to Berlin.
