"Isn't this sealing gel?"
They both recognized what it was at once. Parker said, "This stuff is used for emergency repairs. For example, if there's a hole somewhere on the space station that might cause oxygen to leak out, you use this to seal it up. It's a pretty effective and inexpensive sealant."
The Black scientist nodded as well. "This is fairly cutting-edge technology. It came from China. Compared with other quick-drying sealants, its biggest advantage is its low cost. A bottle costs less than three dollars to make, so you wouldn't feel bad about spraying a few bottles."
"But why is it in this state? Isn't it supposed to be glue?" Natasha wiped her hand clean against the wall in distaste and said, "It feels like some kind of weird alien parasite... Wait, it isn't, is it?"
"Unfortunately, it is," the Black scientist said. "This is a derivative product of the Symbiote Gortal developed in China. No one knows how their scientists came up with using alien biological cells as sealant, but the results are indeed quite good."
"You mean someone sprayed a ring of this stuff around the doorframe on the inside?" After thinking for a moment, Parker said, "Why would he do that? Didn't he know that a door at the Energy Hub's level has one hundred percent airtightness once it's closed?"
"Do many people know that?"
Parker thought for a moment, then shook his head. "Come to think of it, not really. The power department has a lot of repair workers who deal with all kinds of electrical facilities every day, so they more or less understand the space station's systems. Many people in other departments hardly ever leave their offices, so it's normal for them not to know."
"If he didn't know, then he did
