Zhang Zian then realized that they were right next to the aquarium market. As long as they bought an oxygen pump, the ruby octopus might be saved. "Let's do this. You can wait outside while we go inside to buy the oxygen pump and bring it to you," he said. Jiang Feifei had to stay around her stand and could not leave. She was grateful for his gesture. Zhang Zian and Snowy were about to tour around the aquarium market, anyway. It was a small favor they could do for her. They were almost done with the individual stands outside the market building. The remaining stands were quite similar and not worth visiting. After reaching an agreement with Jiang Feifei, the other two went straight into the building of the aquarium market. There were two entrances to the market building––building A and B. Building B was only for aquarium creatures, while building A was for other pets. Zhang Zian and Snowy walked straight into building B. As soon as they entered, the crowd outside the building became distant. There were not many customers in the aquarium market, as it was a work day. Most people were quiet, watching their favorite marine creatures in front of the tank with folded arms and talking to the store owners occasionally. The marine creatures were quiet, as well, unlike the meowing cats and barking dogs. Once one had seen the best, everything else became second best. Since Zhang Zian had been to Karl's aquarium, the market was not impressive at all. The atmosphere, equipment, expertise, and marine creatures were not as eye-catching. But it was fine. He didn't come here to learn, but to buy things like bottom sand, eco-bio-blocks, corals, etc. It was Snowy's first trip to this place and everything was a novelty to her. But she didn't forget her priority, which was to buy an oxygen pump and bring it to Jiang Feifei. They looked at the store plan of building B at the entrance and found out that the first floor was for marine creatures; the second floor for bottom sand, eco-bio-blocks, and other supplies; and the third floor was for different types of aquarium equipment. If Zhang Zian had come here by himself, he might have skipped the third floor, as he already had all the equipment that he needed.
